Video Link

I decided to post this as a text topic since IMO the video description is really important to understanding this performance:

Aug. 29, 2019 | Colin Marshall -- Dan Tepfer has transformed the acoustic piano entirely with his new project, Natural Machines. Watch the keys and you'll see this Disklavier — a player piano — plucking notes on its own. But it's not a prerecorded script.

Here's how it works: Tepfer plays a note, and a computer program he authored reads those notes and tells the piano what to play in response. Tepfer can load different algorithms into the program that determine the pattern of playback, like one that returns the same note, only an octave higher. Another will play the inverted note based on the center of the piano keys. These rules create interesting restrictions that Tepfer says make room for thoughtful improvisation. In his words, he's not writing these songs, so much as writing the way they work. To better communicate what's happening between him and the piano, Tepfer converted these audio-impulse data into visualizations on the screen behind him, displaying in real time the notes he plays followed by the piano's feedback. We dive even deeper into this project in a recent Jazz Night in America video piece.

Perhaps the trickiest part here, unlike a human-to-human duo, is that the computer plays along with 100 percent accuracy based solely on Tepfer's moves. He compares it to dancing with a robot that never misses a beat. Tepfer has to play in kind to keep the train on the tracks, but if he falls out of step, so does the computer. On the other hand, Tepfer has unlocked a new frontier of music available to acoustic piano players: He's essentially given himself more limbs to play the piano at once, and at times we see more than 10 keys pressed at a time or a sequence of notes played at seemingly superhuman speeds. It's a central idea to what innovative technology enables for us — that which is impossible for us to achieve on our own.

edit: Nice related video from Jazz Night in America with Dan explaining some of how it works:

Some of you have read the Typesetting Markdown blog series (https://dave.autonoma.ca/blog/). The plan was to finish the last two parts with Annotated Text (basically markup for Markdown) and Figure Drawing (MetaPost); however, people have asked for a post on Markdown to EPUB, others have asked for high-quality PDF theme templates using ConTeXt, and some have requested rendering Markdown into HTML.

Within the realm of Markdown, digital documentation, typesetting with ConTeXt, R, externalized interpolated strings, and bash scripting, what would interest you for the next post in the series?

(Please flip through the blog series to see the topics that have been covered.)

Notes

Sorry this is posted so late! I would've posted it tomorrow, even, but I'm working all day so I won't have the chance. I'll make sure and bump this thread Sunday, so we can talk about our reading. I'll set an alarm for next time!

Previous topics will be listed in the wiki as soon as I update it.

For those who haven't seen my essay-length posts in the past, I occasionally like to delve into explaining different programming concepts, particularly with regards to making your code easier to manage. Sometimes this has to do with how you structure you code and projects, and at others it has to do with how you think about the problems you're solving. I've been in the mood to write up on yet another programming subject, but nothing in particular has stood out to me lately during the course of my work.

With that in mind, I figured I would take a different approach and see if anyone here had some specific requests for content they would like to see. Requests from all levels of experience are welcome!

(And for those who are itching to do a write-up on any of the requests that appear here, feel free to call dibs!)

Edit

For those who want to take a dive into my previous submissions, you can now find them in the new wiki entry created by @cfabbro or directly via the programming.code_quality_tips tag here.

So I'm just browsing the internet when I should be asleep, and naturally I'm on Reddit. I've read a couple of topics about Aaron Swartz. Comments that get heavily upvoted are things like "the prosecution didn't kill him. he did." ... why does nobody realize this is an incredibly callous thing to say? What the fuck is wrong with people? Why is this acceptable? You'd think more people would take his side or at least be sympathetic.

IMO one of the major issues with online debates, arguments and heated discussions is that they often tend to escalate rather steadily over time, and as each side gets more frustrated with the other they also tend to slowly get more personal as well. I am admittedly guilty of falling into this trap occasionally myself too, which has got me thinking about ways that Tildes (the site and the users here) can potentially help deescalate unproductive arguments and allow people to disengage more effectively from them. To this end I thought it might be a good idea to have a brainstorming session regarding that.

To start things off, here are most of the ideas I could find related to this issue that have previously been proposed and are already on Tildes Gitlab (click ▶ to read the full details):

Feel free to voice your support or criticism regarding the above suggestions, offer up ideas to potentially improve them, or even propose your own brand new ideas related to this issue in the comments here as well.

p.s. Once again, the point here is to open up the conversation and get ideas flowing freely, so let's please try to keep things positive, and keep any criticism purely constructive and friendly so as not to discourage people from participating.

Hi everyone! I'm @acdw, I'm taking over this thread from @cadadr. This is my first one, and I'm excited for the discussion!

If anyone has any suggestions about how to run this thread, please feel free to PM me (I don't want to clog up this thread with suggestions). If there's enough messages, I'll start a thread to discuss them publicly.

The thread about The Wizard of Oz helped me realize there were other musical fans here, and rather than go offtopic in that thread I figured I'd make a whole new one for discussion.

Topic is: musicals. Anything and everything. Tell me about your favorites, the shows you've been to, the songs that make you cry, the numbers you've performed at karaoke, what a talent Sarah Brightman is, how much you had to pay for Hamilton tickets -- whatever! It's all fair game!

I started this last week, and plan to continue posting this topic weekly.

So, what have you been playing lately? Discussion about video games and board games are both welcome. Please don't just make a list of titles, give some thoughts about the game(s) as well.

This thought was brought to you/sponsored by my perception that there's an increasing number of comments on Tildes that attempt to "answer" questions posed in the titles of posts, but don't necessarily demonstrate that the user has read the article before commenting. I won't link specific comments, but I've noticed a fair bit of it as of late. I get that those titles bait people into voicing their opinion, but often it's at the detriment of overall discussion. Should a prerequisite of clicking the actual link in question be a requirement before the user is allowed to post a top level comment? Or perhaps a cooldown period of entering a thread versus commenting may help?

The goal here would be to disincentivise the posting of "driveby" or similarly reductive comments that often don't demonstrate nuance or knowledge that is conveyed in the associated article. Sure, we can't ever know if the user has actually read the article, but it's not designed to be a foolproof strategy, just a discouraging one.

There's a few ways this could be implemented, probably via the utilization of a small bit of javascript that toggle's a user's reading state for a particular post. Thoughts?

Just to clarify since I've edited this post: I mean top-level comments only. Replies are more likely to be in response to the parent comment, rather than the title and wouldn't be affected by this proposal.

I'm writing this in an attempt to explain more clearly some ideas about the dangers of having an oligopoly in control of the Web, and the current difficulties of discussing that without being taken as some kind of "free speech absolutist". It's an analogy and, as in any analogy, it's only valid to a certain extent. The important thing is for it to be valid enough to explain a point.

There was a city in which four companies had ended up owning every bar, except for a handful of them in the outskirts. Upon one moment, they started to regulate which kind of conversations could be held in their bars and which couldn't, something they had a legal right to do and felt was their responsibility. So they prohibited any racist, homophobic or sexually explicit conversation, as well as conversations which they thought could carry any risk for society as a whole. Almost no one could really object to that, after all who would defend that kind of behavior? Some far right gangs said it was against their right to free speech, but they were correctly answered that they didn't have any right to determine the conversation policy of bars that weren't theirs.

Others tried to point that, while that policy wasn't inherently wrong and those companies were in their right to implement it, in the past this was dealt with on a bar-per-bar basis, and although the immense majority of bars didn't allow that kind of behaviors, they had different degrees of flexibility about different topics so bars were more varied and diverse, and you were free to choose a bar which conformed to your interests.

But they were quickly accused of defending some supposed right of that people to be given a place to discuss and organize, and sometimes even accused of defending those ideas. "If you don't like how the Four Companies manage their bars, go elsewhere".

The problem is that the far right gangs and other kind of undesirable people, when forced to leave the Four Companies' bars, went straight to the bars in the outskirts, overflowing them. Some of those bars were already owned by far right people, others though the answer to the Four Companies was to keep a more tolerant policy, and were overtook by neo-nazis. The few independent bars that didn't accept to become far right havens were forced to implement policies not that far from those of the Four Companies, or else face a far right invasion. Their clients spent a lot of time discussing wether something was off-limits or not instead of just enjoying a good time like they did before, and those bars were also very small and far away. They were interesting places, to be sure, but they were cut apart from most of the night life of the city, which took place on the hundreds of Four Companies' bars.

But now, there was a growing problem. The Four Companies had started to prohibit other subjects, for several reasons that aren't really important. Some were distasteful subjects, other were against their political interests or the city council's. But, as the far right gangs kept stabbing people and trying to reclaim their "right" to be accepted into the Four Companies' bars, most people thought that the risk they posed weighed more than anything else.

But they were missing the point. In another nearby city, there were never a handful of companies owning most bars. Still most bars didn't allow far right gangs, and discussion was diverse and fun, and sometimes helpful to combat the excesses of the city council and local police. Still, there were some neo-nazi bars, and most bars had one or two unlikable people. Neo-nazi bars sometimes caused trouble and had to be closed by the police, most were not only under police surveillance but under the neighbors' surveillance too. And, as neo-nazis were a very small minority, if you didn't support the same team as the owner of your closest bar, you could go to another bar which supported your team without it being forcefully full of neo-nazis or otherwise disgusting people.

Both cities had neo-nazis and sometimes problems in their bars, although Four Companies' bars were quite more peaceful on average, as they were heavily policed in a uniform and homogeneous way. But they were lifeless too, and lots of interesting discussions and possibilities of neighbors facing local injustice together were lost forever. Everyone ended up thinking the same, watching the same, liking the same sports and supporting the same teams. Bars weren't a fun and exciting place anymore.

This is just an analogy, so it's limited. But I think it explains well my general view and worries on the subject, which have nothing to do with leaving free way to racists and neo-nazis. It has to do with putting an end to the oligopoly before it's too late.

I have been noticing a disturbing trend in psychedelic groups lately, in which powerful mind-altering substance are being used for emotional and sexual manipulation -- especially among young and vulnerable demographics. In order to combat the collective trauma resulting from these practices, I am attempting to spread harm reduction information far and wide as it pertains to the subject.

Psychedelics facilitate increased intimacy

There is a tenuous association between psychedelics and cliquey, tribal, or cult-like group behavior. This should be taken seriously, especially in large group whose members bond through regular psychedelic sessions. Psychedelics have a number of potential effects that can make individuals more suggestible, and may occasion rapidly-escalating intimacy:

• facilitate deep feelings of connection to others
• induce dissociation, depersonalization and ego loss
• increase suggestibility, making it easier to impress new beliefs or ideas upon the user
• re-expose the user to potentially traumatic memories
• evoke emotional re-association and object transference, including trust and sexual interest that may not otherwise be present
• invoke religious or metaphysical experiences, that instill a sense of meaning and personal significance
• create a sense of paranoia or suspicion, in part as a result of being involved in a potentially illicit activities
• evoke symptoms of mental illness in vulnerable users, making one reliant on external social and economic support

Not all of these effects guarantee problems, but rather indicate how psychedelics can open users up to remarkably strong bonding. The ability of hallucinogens to connect individuals into family-like organizations is notable, as psychedelic have been foundational to many rituals, communities, and cults through history. In part due to these effects, many psychedelic groups exhibit some degree of organizational eccentricity, marked intimacy, or social drama.

Identifying safe group dynamics

If you need help identifying whether or not an organization exercises exploitative practices, consult the following guidelines on cult behavior and gaslighting. Troublesome psychedelic groups are usually large in size and have organized leadership structure, exhibiting the following qualities (as adapted from the Cult Education Institute’s webpage):

• possessing an egotistical leader of social or creative influence, who may have a record of abusing power or individuals
• a rigidly directed ideology, and excluding or punishing members who do not conform to it
• provoking members who are under the influence of psychedelics, or attempting to selfishly influence the psychedelic integration process of another member
• maintaining a culture of misinformation or fear or threats, in which members are easily excluded or blacklisted
• illicit dealings and in-group abuse that is concealed by a culture of secrecy, including: promoting or selling increasingly risky drugs, sexual or romantic grooming, or the use of psychedelics as “tools of seduction”

Perhaps the best takeaway from the association between psychedelics and cult activity is this: psychedelics have the ability to destabilize and rearrange one’s sense of self, which makes them more susceptible to peer pressure and the influence of others. For users who already are mentally liable or require a secure mindset and setting, it is essential to make sure that they feel in control of their drug use, and have the personal autonomy to ensure their trips are safe and serve personal growth.

The Cult Education Institute’s signs of a safe group/leader are also adapted below:

• can be asked questions without judgement
• discloses ample information such as structural organization/finances
• may have disgruntled former followers, but will not vilify, excommunicate, or forbid others from associating with them
• will not have a record of overwhelmingly negative articles and statements about them
• encourages family communication, community interaction, and existing friendships
• encourages critical thinking, individual autonomy, self-esteem, and personal growth
• leaders admit failings and mistakes, accepts criticism, and follow through on implementing constructive changes
• operates democratically and encourages accountability and oversight
• leader is not be the only source of knowledge excluding everyone else; group values dialogues and the free exchange of ideas
• members and leaders recognize clear emotional, physical, and emotional boundaries when dealing with others

Gaslighting & manipulation tactics

Many of the tactics that both individuals and groups use to manipulate people are examples of gaslighting, or attempts at convincing members that they are somehow mentally compromised in order to control them. This is often done by withholding information from them, invalidating the victim’s experiences, verbal abuse (including jokes), social isolation, trivializing the victim’s worth, and otherwise undermining their thought process. When combined with the suggestion-enhancing properties of psychedelic drugs, these kinds of behavior can be traumatizing to individual victims, while remaining relatively undetected or overlooked by onlookers.

In order to help identify gaslighting by a group, consider if you relate to its effects, as described by Robin Stern in her book The Gaslight Effect:

• constantly second-guessing yourself, feeling confused, or as if something is wrong
• asking yourself “Am I too sensitive?” throughout the day
• frequently apologizing to people who hold power over you, feeling as if you can’t do anything right, or running over things you may have done wrong
• frequently wondering if you are “good enough”
• frequently withholding information from your friends or family so you don’t have to explain the group or make excuses for it
• you lie to group members, to avoid being put down or gaslighted
• paranoia about bringing up innocent conversation topics
• speaking to group leaders through another member, so you don’t have be worry about the leaders becoming upset with you
• making excuses for group members’ behavior to your friends and family
• friends or family try to protect you from the group
• becoming furious with people you used to get along with

If you suspect you have been involved in a psychedelic cult or gaslighted, you may be experiencing regular instability, dissociation, or feelings of uncertainty. Although it can be difficult at first, finding a new group that demonstrates a high degree of member safety and accountability may help rebuild one’s sense of safety and trust. If you shared psychedelic experiences with group members while being taken advantage of, it may be beneficial to seek out a professional psychedelic integration therapist to help emotionally contextualize these memories. Victims may also benefit from adjunct trauma therapies, such as Dialectical Behavioral Therapy (DBT) and Radically-Open DBT, somatic bodywork and movement therapies, therapeutic massage, and other complementary therapy practices.

Inspired by @Lawrencium265's suggestion from a few days ago on advanced topic tag filtering:

After the discussion the other day on expanding groups into sub groups I had an idea about topic tags, advanced tag filtering rules. The main argument against sub groups is that it would sequester people away from each other. By allowing more advanced tag rules you could subscribe to topics that you're interested in, but further filter those if they include topics you don't like or allow certain threads that would get filtered out unless they contain a tag you are interested in or are within a certain group. I think this would attract different people to threads that wouldn't normally be and allow more diverse discussion and insight. So instead of having gaming.tabletop you would use the tabletop tag under gaming and those who are not interested in it can filter it out and those who are solely interested in it can subscribe to it, and then if a topic gets tagged in an unrelated group that you otherwise wouldn't be interested inyou will know about. This also has the side benefit if preventing cross posting or duplicates.

I have decided that the topic of this week's unofficial discussion is going to be on the Tildes topic tag system. But rather than make it specifically on topic tag filtering and that idea in particular, I figured we could open the discussion up a bit more and have a community brainstorming session on the topic tag system in general. I.e. Anything related to tag browsing, tag filtering, tag organization/standardization, etc.

Feel free to comment on any of the open "topic tag" related issues on Tildes Gitlab that pique your interest and you would like to discuss more in depth, propose your own new ideas related to topic tags, or even just spitball.

The point here is to open up the conversation and get ideas flowing freely, so with that in mind, let's please try to keep things positive, and keep any criticism purely constructive and friendly so as not to discourage people from participating.

A few of the other groups have been doing recurring topics like this, and I think we should really do it more regularly in ~games too.

So, what have you been playing lately? (Please don't just make a list of titles, give some thoughts about the game as well.)

after a month sabbatical, we're back. this is pretty straightforward, i think: vent your experiences or things you need to get off your chest/share whatever you've found helps you mentally/etc.

resources that might also be of some benefit to people:

• there is, as always, the invaluable list of country hotlines maintained by /r/SuicideWatch
• https://findtreatment.samhsa.gov/ ("an online source of information for persons seeking treatment facilities in the United States or U.S. Territories for substance abuse/addiction and/or mental health problems")
• https://therapists.psychologytoday.com/rms/ (probably one of the best resources for finding a therapist)
• https://psychiatrists.psychologytoday.com/rms (ditto, with finding a psychiatrist)

Notes

First of all, I'm again having to post the topic earlier b/c travel. Sorry.

Seconly, big news! It's already been almost a year that we do these threads! It's been a beautiful time for me, but I've decided that the time has come that I pass the torch on to another Tildista to post and manage these threads. I posted a topic on ~tildes declaring my decision; we held a vote and elected @acdw as the new maintainer of these threads. This is the last one of these topics that I'll post; from the next thread on @acdw will be taking over. FWIW, I'll stay around and comment on these threads when I can.

Hey @acdw, hope you'll have a great time doing this! Good luck!

My mom is almost 65 and she's pretty heavy. It has got to the point where it's affecting her life quality - she often has joint pain, heart problems, clogged arteries... She has to lose weight, basically. Problem is, I feel like she has no motivation to do so. She never even tried doing it. I researched a bit online, and it seems like older people have it harder to lose weight, not just mentally, but also physically because they have less muscle mass and stuff. Is there anyone more knowledgeable on this topic?

we need more casual questions in here (there are 4 topics specifically tagged casual on the first page rn), so let me cast the first stone to that lot. bonus style points if you link to what the food is if it's country specific/kinda esoteric/something most people wouldn't know

The lack of ability to combine search functions on Tildes is becoming more and more of a pain point for me. I can filter for one tag or search for one word, but that's it. I can't narrow the search in any way. I can't combine searches and filters and groups:

• I can't search for a word within a group.

• I can't search for a word within a set of topics filtered by a tag.

• I can't filter by two separate tags at the same time.

• I can't search for two separate words at the same time.

As Tildes is growing larger, the ability to search better is becoming more necessary.

Is there any possibility of bringing forward the work on searches so that some of these combinations can be enabled?

Since @Deimos has stated he will likely not be restarting the tradition of the Official Daily Tildes Discussions, which is something I and a number of other users greatly enjoyed and miss, I have decided to attempt to take on the responsibility of continuing them unofficially (with his blessing). And since these are not official (so won't be in ~tildes.official, which everyone is subscribed to and probably shouldn't unsubscribe from), I will only be doing them weekly instead of daily, and we now have topic tag filtering (so unofficial weekly discussion can be filtered out), hopefully the people who found the official daily discussions annoying can more easily ignore/hide these unofficial ones.

With the explanation out of the way, on to the topic for this week:

Suggestions/ideas/concerns for future unofficial weekly discussions

I thought it would be appropriate to have the first one of these be a bit of an open-ended, meta-meta discussion on the future of these topics. And to kick things off:

• What would everyone here like to see discussed in these topics in the future? Are there any particular site features (planned, suggested or theoretical), policies (tagging, moderation, etc), or other meta issues/subjects you would like to be the topic in future discussions?

• What would you like us to try to achieve with these discussions? Should we have any specific goals in mind, or should they just be fun brainstorming/theory-crafting/naval-gazing sessions?

• Does anyone have any suggestions for me with regards to how I should handle these discussions? Is there anyone out there who would like to help me with these in some capacity going forwards?

• Does anyone have any concerns regarding these unofficial discussions, and if so, can you think of any ways we can try to address them?

The floor is open, and I am all ears. :)

I am considering starting a wiki project for an academic niche. I've already started prototyping using Gitit, I've written a bit easy pages to get a feel for the software and am planning to start working on the most important page that summarises the topic itself, which I believe will help guide me to which pages to create first.

Now, here I'm asking for general advice to a newcomer n00bie wiki admin like me: what to expect, what software, etc. Any advice welcome, but I'll list a few questions below:

• What wiki software? I am liking Gitit, it is nice and easy to set up, and comes with its own server which I run with a systemctl user unit in the background. I tried Oddmuse but couldn't get it to work with a simple server; Ikiwiki setup is too clumsy for my liking (it friggin put stuff on my $HOME by default!); I want to avoid PHP stuff in general; I want a simple wiki that serves simple HTML pages.

• How to defend against spam? My plan is to keep it invite-only for as long as I can. IDK how to do that with Gitit yet.

• How to serve it securely and for cheap, once I decide to publish? It probably won't ever grow beyond a few dozens of megabytes in file size.

• How do you go about promoting a wiki?

• What peripheral services (issue tracker, mailing list, IRC/Discord/etc channels) go well with a wiki?

• What tools are available to ensure content quality (no plagiarism, enforce conventions, monitor changes, ...)?

If someone posts on a one month old thread, it shouldn't make it to front page.

If someone post on a new 1 day old thread, if should, but not at top, but... somewhere else. A method of weighting oldness vs liveness should play there.

I've been posting these since time immemorial 9 months by now. Since almost the first post my plan was to hand the responsibility of posting them over to someone; as of recent it seems to me that soon I'll lack the time to properly participate in them as the organiser that keeps the discussion alive and fruitful. In fact, the last few posts I've either posted one comment or none at all.

So maybe the 25th or the 26th topic should be posted by the New Guy™? Has the time come? My answer is yes, TBH. In the comments, you can criticise my decision, call me lazy, or name yourself as a candidate freely. I guess we'll use votes on candidate comments to determine the next guy. If there is a tie, I'll name one of them as the next guy (tell me in the comments if you disagree with this). Voting will be over roughly when this post becomes three days old. I don't think too much precision is required, or else we can try something else.

IDK if this is a nice way to do it, but I don't want to do this Guido van Rossum style—say "bye, figure this out for yourselves, you lot" and leave. Hope I'm not over- or underdoing it. I'll ask a few prolific posters to name themselves as candidates through PMs.

Edit: I'll close voting around 3 PM UTC+3 24th of July, which means I'll edit to record votes I see by that time, including a timestamp. I'll then speak to the user with the highest amount of votes, informing them of the (rather simple) process of posting and maintaining these threads. Most probably, from #25 onwards, the new guy will take over.

Thanks a lot for taking this seriously and helping this nice feature of ~books move on with a new maintainer!

Edit 2: I'm closing votes, it's 24th of July 2019, 18:20 UTC+3. @acdw has 10 votes, @iiv has 6. I'll contact @acdw, and the next WAYRC topic will include an announcement. Thanks a lot for your participation and interest in the future of this fun little thing we do!

Notes

• Sorry for posting late this time round. I had an intense week, and was basically too lazy to post yesterday.

• I will not include a list of past topics in the topic text anymore, given it is redundant with the listing in the wiki. Below you'll find a link to the relevant section in the relevant wiki page instead. If you think this is a bad change, PM me about it; if a lot of you don't like it I might end up reverting this.

• Have a nice weekend!

I find it hard to find articles that I think more people should read.. I find most of them pretty much spam (cough medium cough). I created this thread so you can recommend some articles that you read and found interesting.

It doesn't matter about what it is, recommend away!

This is kind of a question for Tildes as well as a discussion topic on Social Media more generally. For context, "The Right to be Forgotten" is an idea being kicked around in international law and human rights circles. It's kind of a corollary to the "right to privacy" and focuses on putting some guardrails around the downsides of having all information about you being archived, searchable, and publicly available forever and ever. It's usually phrased as a sense that people shouldn't be tied down indefinitely by stigmatizing actions they've done in "the past" (which is usually interpreted as long enough ago that you're not the same person anymore).

This manifests in some examples large and small. Felony convictions or drug offenses are a pretty big one. Another public issue was James Gunn getting raked over the coals for homophobic quotes from a long time ago. Even on a smaller scale, I think plenty of young people have some generalized anxiety about embarrassing videos, photos, Facebook statuses, forum posts, etc. that they made when they were young following them around the rest of their lives. For example, Alexandria Ocasio Cortez had people try to shame her for dancing to a Phoenix song in an amateur music video. An even darker version of this happens with people who might be the victims of targeted harassment. Often doxxing happens by people digging through peoples' histories and piecing together clues to figure out who they are or at least narrow down where they're from, where they work, etc.

In the context of Tildes, this would basically be a question of how do we feel about peoples' comment history lingering forever? Do we care about/agree with this "right" in principle and if we do, what should be done about putting it into practice?

The root of the issue is the existence of archives of data about yourself that is 1.) searchable, 2.) publicly viewable, 3.) under someone else's control, 4.) forever. Even if the ability to delete comments exists, it's infeasible for any individual to pore over the reams of data they create about themselves to find the stuff that might be problematic. The solutions would revolve around addressing any one of those numbered items. Unfortunately, hitting any of those has upsides and downsizes. Some examples:

Some people like being able to look back on old contributions and having them get deleted after a period of time (hitting problem #4) would be a bummer unless there is a system to selectively archive stuff you want to save from atrophy, which would be a function/feature that would take a ton of thought and development. What's more, there is no point in just saving your own comment if everyone else's stuff is gone because comments without context are indecipherable. It could work in a more selective way, so rather than a blanket atrophying of posts, but then you have the context issue again. Someone you were having a discussion with might choose to delete their entire comment history and there goes any sense of logic or coherence to your posts.

We could address the searchable bit by automatically or selectively having posts pseudonymed after a period of time. But in a lot of cases a pseudonym won't work. People tend to refer to each other by username at times, and some people have a distinctive enough style that you could probably figure it out if they're well known and long-tenured.

That's just some general food for thought. I'll yield the floor

No genre restrictions, so a tell-all memoir is as valid a response as a high-fantasy tome. Maybe you want to dive in deep on an anthropological topic, or maybe you want to pen a full book of contemporary political commentary. Any and all options are on the table, with the only caveat being that you'd have to write enough to fill a book, so it would have to be an area of knowledge or passion for you--likely both.

Also, for those here that have already written books, feel free to talk about those if you like, or one you hope to write in the future.

For those that haven't, don't feel constrained by real-world concerns/inhibitions. Pretend you have the time and resources to adequately devote to the book to fully see your vision through.

Make sure you give us:

• A summary of what the book would be about
• An explanation of why you'd want to write that specific book
• And, most importantly, a good title!

First up: that “spoiler” tag isn’t there for fun. This essay is going to focus on a climactic moment in ‘Toy Story 4’. If you haven’t seen it and don’t want to know what happens, close this topic NOW.

I saw ‘Toy Story 4’ last night. I’ve been catching myself up on the previous movies over the past few weeks (I’d never seen any of them before), so they’re reasonably fresh in my mind. I surprised myself by enjoying the movies a bit more than I expected to. I had assumed they were very much children’s movies, but I found them engaging and enjoyable even as a middle-aged adult.

So I was all caught up, and went out last night to see the latest instalment in the franchise with a friend who’s a massive fan of all things Disney.

I liked it. It was yet another “toys having adventures in the big wide world” story line. That seems to be the main story line of all the Toy Story movies: the toys get lost or misplaced, or have to go rescue a toy who is lost or misplaced, so they end up having adventures outside of their home.

But there’s usually an emotional heart to each movie. And that emotional heart often comes from the character of Woody, whose goal has always been to make sure that the toys are doing what toys are supposed to do: bringing joy to children. As we often get told, mostly by Woody, being a child’s plaything is the most noble thing a toy can do. To that end, Woody seems willing to do almost anything. The toys have mounted ridiculous rescue missions, they’ve manipulated humans (it wasn’t Andy’s idea to give his toys to Bonnie), and they’ve made personal sacrifices. Even in this movie, Woody was willing to give up his voice box so that he could get brand-new toy Forky back to Bonnie who had made him, and to give Gabby the chance to belong to a kid.

Then…

Woody met Bo Peep in this movie, and found her living an independent life as a lost toy. We know they’ve had romantic feelings towards each other, but she was given away by Andy’s little sister some years back. Then she got given away again, to an antique store. Now she turns up living near a caravan park, and she’s noone’s toy except her own.

Normally, Woody would have moved heaven and earth to reunite Bo with her previous kid, or to find her a new one. But she doesn’t want one. She’s an independent toy now, and that suits her fine.

So they have their adventures. And, at the end of those adventures, Woody and his fellow toys are returning to Bonnie, while Bo is returning to her independent life. And Woody has a moment of indecision. Does he return to Bonnie, or does he go with Bo?

But, there’s not really that much tension because we know how this is going to end. Woody has told us so many times that being a child’s plaything is the most noble thing a toy can do. Of course he’s going back to Bonnie.

And then he chooses to go with Bo.

I sobbed.

Let me give some context for my reaction to this moment. I do respond emotionally to movies and television. I laugh loudly when something is funny, and I cry openly when something is sad. I jolt back in my seat in response to scary moments, and I’ve been known to cover my eyes during exceptionally gory scenes. I’m not ashamed to feel things in response to events on the screen, nor to express those feelings. That’s normal for me. However, I felt a very strong emotional reaction to this moment in the movie – much stronger than most. I wanted to burst out in loud unmanly sobs because of how upset I was. I wanted to shout at the screen. I felt a real and physical reaction in my gut: it was literally a gut-wrenching moment for me (and that almost never happens!). This was the strongest emotional reaction I’ve had to any moment in movies or television for years. It was strong enough to prompt me to write about it!

I know I was supposed to feel happy that Woody and Bo had found each other, and they loved each other, and this was the start of their romantic “happy ever after”. But that’s not why I cried. I cried because Woody turned his back on nobility and chose selfishness.

Woody had been the conscience and the heart of the whole franchise, reconciling toys to their place in life, and helping toys to achieve their goal in life. Even in this movie, he had turned Forky around from wanting to be trash to wanting to help Bonnie. Woody showed toys their noble goal in life, and did everything he could to help them achieve it.

And then he turned his back on everything he’d said and believed up till now.

Sure, Bonnie wasn’t playing with him as much as Andy did. Sure, he wasn’t top dog in Bonnie’s playroom (that place belonged to Dolly, who’d been there much longer than Woody and his fellows). But Woody was always selfless. Woody was always looking out for the children’s best interests. Woody was always putting the children’s needs ahead of his own. He had previously told his fellow toys that even being stored in the attic was a good thing because it meant their child (now a college man) still cared about them to some degree. So, even if Bonnie wasn’t playing with him all the time, he would still want to stay around to be there for her – or even to be there for the other toys she did play with.

Wouldn’t he?

Or was it all a lie? Was it all about his own selfish desire to be important and, then, when that importance was taken away, he decided to walk out?

Or was it as basic as choosing pleasure over service?

How could you do that, Woody? How could you turn your back on everything noble and good, and choose your own selfish desires instead?

Woody, you broke my heart.

What's a song lyric that has recently jumped out at you, caught your attention, resonated, or made you think?

This doesn't have to be a favorite/best of all time topic, though feel free to post those if they speak to you. I'm more interested in something you encountered recently that you really like, appreciate, or find interesting, for whatever reason.

Given a movie with ambiguous story, you have multiple options to base your interpretation upon: you have the movie itself, the screenplay if available, what the author said in interviews or books, etc... Now, if we take a video game, you also have additional tools: the source code, the installed file names, unused resources, etc. There are of course a few games that expect the player to check these files but that isn't what I want to focus on.

Would you say that all these files have the same authority as the game itself when it comes to interpretations?

I'd like to take an example with SPOILERS FOR LIFE IS STRANGE 1, as this is the game that sparked this topic for me:

The blue butterfly has a special place in this game, it is what starts the whole journey when Max takes a picture of it and Chloe gets shot. It also shown again in the 'Sacrifice Chloe' ending during that same scene. And later during Chloe's burial that butterfly is shown to land on the coffin in front of Max and fly away. There are some scenes that imply that spirit animals are a thing in the in-game universe. After finishing the game my interpretation was that the blue butterfly was Chloe's spirit animal. Now what a surprise to see in the game wiki that the texture file for that butterfly is named 'Spirit_animal_Chloe' !

Is there any room left for interpretation when the source makes it explicit text? Or can the source be reasonably be pushed aside?

oops, had a space in url last time.
So still not a valid link as topic link

But does make a weird un-clickable link in md.

While the link does not go anywhere, could a malicious link do anything bad sec-wise?

fyi, the link is to: data:text/html,<h1>Hello%2C%20World!<%2Fh1>

This was inspired by this post.

I was thinking, as a platform gets bigger we're going to end up with more situations where people are asking for advice about fairly serious stuff. In some cases, that advice needs to come from experts and taking guidance from any random Joe on the street can be risky/dangerous. (For the record, I don't think the post I'm referencing is an example of this, it just got me thinking about it).

In cases like this, I think it's important that the actual good advice get some kind of clear designation that THIS is the guidance you need to take first. I notice this in communities like /r/Fitness a lot where people will post about what sound like pretty serious health concerns and you get a fair number of posts that suggest toughing it out or whatever and the more critical "You need to see a doctor" posts can kind of disappear amid the discussion. Similar things in /r/relationships where you can't always count on "This is abuse. Make arrangements to get your kids and yourself somewhere safe. . ." to be the top post.

Even in cases where the poster themselves is smart enough to take "YOU NEED TO SEE A DOCTOR" type advice to heart, not every schmuck searching the topic on Google will. To that end, it might be good to give certain posts with good, holistic advice or by a known expert some kind of visual indicator that it deserves to be taken more seriously than other posts in the thread. It wouldn't be censoring anything really, just providing a little nudge about what ought to be consulted first or taken to heart.

Now obviously it gets hard to decide how to give a post this attribute. It could possibly be awarded by the OP, though that has some obvious issues where the OP themselves might not be in a position to credibly vet the advice they're getting. We could also just do it through ranking by vote, which is the default paradigm. But like I said, it doesn't always work so well on Reddit. And the Exemplary tag is invisible to others, so that doesn't work either (and the post itself might not be worth giving up your "Exemplary" for the day besides). Moderators could do it, but there may not be enough and the skillset to be a Mod might not overlap with the skillset to know what advice a person needs in a particular situation.

I don't actually have the answers. Maybe it just comes down to creating an attribute for some users to be "wisened elders" or something and empower them to star certain posts to separate good advice from bad. It would basically be a trusted user system. It's got it's own problems, but I guess we can open the floor for other ideas. Maybe it's not a real concern. Maybe it's better addressed by tinkering with the sorting of posts.

I am working on an app called Percent Done that is a combination of goal setting, time tracking and habit tracking.

I like setting time-based goals for myself every day, such as “write for an hour” or “work on Percent Done for four hours.”

I also like Seinfeld’s “don’t break the chain” method. For example, Apple Watch shows you how many days you have completed your exercise circle and tells you that you have been keeping at it for x days.

Percent Done is a marriage of these two concepts. It allows you to set goals and track the time you spend on them, as well as how many days in a row you have consistently completed them. For example, you can add a goal that says “write for an hour every day,” and Percent Done will notify you every day to write for an hour. You will be able to tap on this goal and Percent Done will start counting back from one hour. You will also be able to see how many days in a row you have written for an hour.

Here is a demo GIF.

You can also add one-time goals to Percent Done with or without time tracking, so it is a task management tool as well.

You can play with the design prototype here: Percent Done design prototype

I would really love to get your feedback on this. If you are interested in being a beta tester, feel free to reply to this topic or e-mail me at "hi at evrim dot io."

By the way, this is almost completely a self-promotion post. If it is against the rules, I'd be happy to remove this.

I apologize if this is the wrong topic for this post, and if this feature already exists, I apologize for that too. I looked around and couldn't find it (it's possible I could have missed it). But I thought a dark mode for Tildes would be most excellent. Right now, there's a lot of white space and combined with my 24" monitor, this site lights up my whole room like it's in the middle of the day. Anyways, thanks for reading. :)

Introduction

I want to give an introduction on several physics topics at a level understandable to laypeople (high school level physics background). Making physics accessible to laypeople is a much discussed topic at universities. It can be very hard to translate the professional terms into a language understandable by people outside the field. So I will take this opportunity to challenge myself to (hopefully) create an understandable introduction to interesting topics in modern physics. To this end, I will take liberties in explaining things, and not always go for full scientific accuracy, while hopefully still getting the core concepts across. If a more in-depth explanation is wanted, please ask in the comments and I will do my best to answer.

Today's topic

Today's topic is spintronics storage devices for computers. I will try to explain how we can use an electron's spin to read and write data and why this is more efficient than current technologies.

What do we need to have a storage device?

In order to be able to save a bit (a 0 or a 1 in computer science speak), we need to be able to represent both the 0 and the 1 in some physical way. We could for example flip a light switch and say light on is 1, light off is 0. We will also need to be able to read the information we stored, in this case we can simply look at the lamp to see if we're storing a 0 or a 1. We would also like for this information to be stored even when power is cut, so that next time we power the hardware back on, we will still be able to read the data. Lastly, we want to be able to change between 0 and 1 freely; no one wants to go back to the CD days for storage.

Now for some basic concepts.

What is spin?

Spin arises from quantum mechanics. However, for the purpose of explaining spin storage devices we can think of an electron's spin as a bar magnet. Each electron can be thought of as a freely rotating bar magnet that will align itself with the fields from nearby magnets. Think of it as a compass (the electron) aligning itself to a fridge magnet when it's held near the compass.

Why are some metals magnetic?

Why can we make permanent magnets out of iron, but not copper? In all metals, we have spins that are free to rotate. This means that we can turn a metal into a magnet by holding it near another magnet, it will "copy" the other magnet's magnetisation - its spins will rotate in the direction of the field. But as soon as we remove the magnet, our metal will stop being magnetic. This is because the spins are freely rotating, the spins will align to the magnet's magnetisation when they feel it, but nothing is holding them in place as soon as it's removed. We call this property paramagnetism.

However, iron (and some other metals) will retain a nearby magnet's magnetisation even when the magnet is removed. This is because in these materials, called ferromagnets, it costs energy for the spins to rotate away from the material's magnetisation. They are pinned into place.

What happens if we expose half of our ferromagnet to a magnetisation pointing in one way (let's call it up), and the other half to a magnet whose magnetisation is pointing the other way (which we call down)? The ferromagnet would copy both magnetisation directions and create a boundary region - a so-called domain wall - in the centre. The spins in this domain wall will slowly rotate over the thickness of the wall so that at one end they're pointing up and at the other end they're pointing down.

How can we use spin to store data?

What if, instead of a light bulb, we used a bar magnet as our storage medium. We could magnetise our bar magnet in one direction to store a 1 and magnetise it in the other direction to store a 0. To read what we have stored, we simply check the bar magnet's magnetisation.

Let's work out this idea. We want to be able to efficiently change the magnetisation of a bar magnet and we want to be able to read the bar magnet's magnetisation. We will use a ferromagnet because it will retain our data indefinitely (its magnetisation will not change unless we force it to). We know it costs energy to flip the spins inside a ferromagnet, so we will want to use a very tiny ferromagnet - it will have less spins which means it will cost us less energy to change the magnetisation (i.e. flip the spins).

Magnetoresistance

A-ha, now we're getting into the fancy-titled paragraphs. What do you, dear reader, think would happen when we send a current (e.g. a bunch of electrons) through a magnet? What would happen to the current's electrons (also called itinerant electrons, to distinguish them from the non-moving electrons of the metal)? At the boundary of the magnet, where the current enters, only the electrons who (through random chance) have a spin that's aligned to the magnet's magnetisation will pass through. We call this effect magnetoresistance, as in effect part of our current will feel a resistance - they cannot pass through to the magnet. So to rephrase, the current inside the magnet will be "magnetised" - all of the spins of the itinerant electrons are pointing the same way.

Current induced domain wall motion

So now we know what happens to a current that's inside a magnet. What happens when this current meets a domain wall - the region where the magnetisation changes direction? The itinerant electrons' spins will start rotating along with the magnetisation, but the static electrons of the ferromagnet will also start rotating in the opposite way due to the magnetisation they feel from the current (more experienced readers will recognise this as conservation of angular momentum). So the spins inside the current will slowly rotate until they are pointing the opposite direction and can continue passage from the up-magnetised part of the ferromagnet into the down-magnetised part. But the spins that belong to the ferromagnet itself will be rotating in the opposite manner, slowly rotating from down to up as the current passes through. This means the boundary region between up and down magnetisation, the domain wall, will move along with the current.

So in short, by sending a current through a magnet that's magnetised in opposite directions at each end, we can force our preferred magnetisation to expand in the current's direction. By reversing the direction of the current we can then magnetise the other way again.

So we can say magnetising up (pushing current through (let's say) from left to right) can be our 1 and magnetising down (pushing current through from right to left) can be our 0. This would allow us to store data permanently as even when we remove the current our magnet will remember its magnetisation. If we make a really tiny ferromagnet we will only need a really tiny current to flip it's magnetisation too. So we can scale this process down to get to really good efficiencies. In the lab these types of devices are down to nanometre scale and require extremely little current to be operated.

Reading the data

OK, so now we know how to write data. But how do we read it? The key effect here will be magnetoresistance, as explained earlier in the post.

Let's look at this picture. The red dotted line shows our write currents, the big bar is our ferromagnet. The arrows pointing up and down at the sides are our magnetisation direction, the double-pointed arrow in the centre shows the region where we flip the magnetisation by sending through a current.

Now we jam a third, permanently magnetised, bit of metal (let's call it the read terminal) on top of the centre of our bar. We send a current from this read connector to one of the ends of the ferromagnet. If the ferromagnet's magnetisation is aligned to that of the read terminal we will experience a low (magneto)resistance, but if the ferromagnet is magnetised in the opposite direction we will experience a high resistance. By measuring the difference in resistance we can determine if we have a 0 or a 1 stored. We just need to be careful not to send too big of a current, else that would influence our ferromagnet's magnetisation. But small currents means better efficiency, so this is not a problem at all.

Conclusion

This concludes the post, we have seen how to use spins and magnets to both write and read data and we understand why this is efficient.

Feedback

As usual, please let me know where I missed the mark. Also let me know if things are not clear to you, I will try to explain further in the comments!

Neon Genesis Evangelion is out on Netflix. I'm thinking to use this topic as the megathread to discuss the (re-)watch, to avoid flooding the Tildes Activity feed with one topic per episode.

To borrow a past Tildo's approach, I ask that any top-level comments contain ONLY the episode number, such as "Episode 13" and no other text.

Press the Collapse replies button, find the top-level comment for the episode you care about, and reply under that top-level comment. If there's not yet a top-level comment with that episode number, create it.

Hey everyone! I was browsing around and came across this old topic again, late 2000's skeuomorphisism vs modern flat design. I've always strongly preferred the former for a variety of reasons and thought flat design was a regression, but I was curious, what do you guys think?

welcome to week twelve, one day late edition. this delay is brought to you by the weirdly confined issue to the file i wrote this in, which necessitated three days(!) of writing because of the sheer number of links this week. the opinion section is only one article long this week again, but we have some [LONGFORM] pieces and some recent polling to make up for that.

the usual note: common sense should be able to generally dictate what does and does not get posted in this thread. if it's big news or feels like big news, probably make it its own post instead of lobbing it in here. like the other weekly threads, this one is going to try to focus on things that are still discussion worthy, but wouldn't necessarily make good/unique/non-repetitive discussion starters as their own posts.

General Stuff

• from Vox: Poll: a growing number of Democratic voters are prioritizing gender-related issues we begin with some polling, which suggests that the recent slate of abortion bans and heavy restrictions on abortion is having an impact on what voters prioritize. a doubling of democratic voters who prioritize women's issues has been observed across the board in the span of just a month. this might not be maintained if the slate of abortion bans gradually dies off, but at least in the immediate term you definitely seem to be seeing this in how often these issues are mentioned in the media.
• from Vox: 2020 is quickly becoming the abortion rights election. Here’s proof. also from Vox, in a similar vein some activists are considering 2020 the year of the abortion rights, and the 2020 election a defining election on them. in iowa, for example, it was ranked the top issue of caucusgoers, placing ahead of climate change narrowly. this piece is primarily a conversation focusing on the issues surrounding abortion and how activists think it will play out in this election cycle.
• from Pacific Standard: Can Cory Booker, Elizabeth Warren, and U.S. Cities End Exclusionary Zoning?. exclusionary zoning policies are something that's gotten attention from a few candidates, most obviously cory booker and elizabeth warren who both have plans which seek to end it. zoning policies are but one part of a greater issue in affordable housing, but the fact that candidates are even bothering to take the time to acknowledge its existence probably demonstrates something about what an issue housing is for a lot of people.
• from CBS News: Some progressives worry Puerto Rico is being left behind on 2020 campaign trail. despite the focus on the complete bottling of aid being sent to puerto rico by the trump administration, a number of progressive groups are concerned that puerto rico is being largely left out of the conversation when it comes to 2020. puerto rico has been largely ignored by candidates so far (only 3 of the candidates in the race have visited the island so far) and is still recovering from hurricane maria; nonetheless, progressives seem ready to make it a defining issue of the campaign trail.
• from Slate: The Democratic Candidates Ought to Debate Climate Change Policy. one of this week's plotlines with respect to the debates was the DNC's unwillingness to agree to a debate specifically on the issue of climate change. this has been a generally poorly received move, and the party has received considerable backlash for it as this piece is representative of. the DNC might walk this back or it might not, but regardless this seems like it will be an issue that causes future friction, especially given the DNC's expressed desire to uninvite anybody who qualifies for the debates should they engage in a non-DNC affiliated one.
• from Buzzfeed News: California’s Early 2020 Primary Is Pushing Presidential Candidates To Talk To Latino Voters. the california primary coming so early on in the cycle and being such a decisive part of it in 2020 is leading to democratic candidates placing significant priority on appealing to latino voters this year, who are likely to be a major constituency in the primary. this is a welcome change for a lot of latinos and the state of california in general, which has generally come late in the cycle previously and not played an especially significant role in most of them.
• from the Atlantic: [LONGFORM] How the Democrats Got Radicalized on Student Debt. the recent policy developments of the democrats on student debt are the focus of this article by the Atlantic. this has been a rapid change for the party; in the span of just three election cycles the party has gone from "one year of college free for “qualified students”" (the John Edwards proposal, 2008) to things like "making public college tuition-free for students from families who made less than $125,000 a year" (Clinton, 2016) and probably beyond in this cycle.

Joe Biden

• from Grist: Joe Biden says he’ll take the No Fossil Fuel Money Pledge. Here’s why that matters. joe biden, in rolling out his climate plan next week, also became the latest candidate to take the "no fossil fuel money" pledge, which most candidates have also taken (and which counterintuitively allows candidates to take donations of less than 200 dollars from the fossil fuel industry). biden's acceptance of this--even though it is far from binding--is particularly significant because it suggests that the progressive wing of the party has basically forced people's hands on this.
• from In These Times: [LONGFORM] Hold the Applause. Biden’s Climate Plan Is Mostly Fluff. meanwhile, In These Times has an extensive critique of biden's climate plan; primarily it notes that biden's plan when you strip it down is not that special and is essentially shared by the rest of the field which has rolled out plans so far at its best moments. at others, it is actively misleading, relies on technological optimism as a crutch, or implies biden supports things like the green new deal which he for the most part does not.
• from the Atlantic: Joe Biden Has the Most to Lose at the Debates. the Atlantic has a piece on joe biden, his near total lack of experience with debates in the past decade, and his debate prep in light of that fact. biden's last serious debate was of course 7 years ago when he faced off against then-VP candidate paul ryan; however, as far as debating other democrats goes, he hasn't done that in a decade. the majority of his prep is centered around trying to stave off the inevitable questions about his record and his positions while presenting himself as a viable alternative to both other democrats and to trump (not that most people necessarily need convincing on the last point)
• from the Guardian: Biden abruptly drops support for 'discriminatory' abortion rule. in policy news, biden decided to do a weird and wholly unnecessary flip-flop on the hyde amendment after originally affirming his continued support for it ,and then having to immediately walk his support of it back when it turned out that literally nobody else but him supported it in the democratic primary. great look, joe.
• from Pacific Standard: Green Jobs and New Technology: A Look at Biden and Warren's Latest Climate Plans. this small article from Pacific Standard compares warren and biden's climate plans together on a number of issues, since they are actually fairly similar in a number of respects despite their ideas being relatively different as a whole.

Elizabeth Warren

• from the Guardian: Elizabeth Warren gains momentum in the 2020 race plan by plan. warren has continued her quiet, but consistent rise in the polls; she's currently pushing some of her best numbers thus far in the campaign in multiple polls. this is good for her campaign of course, but it's also a bit of a potential quagmire for progressives because with sanders and warren both splitting the difference of mostly the same voting demographics, it's unlikely that biden will relinquish his lead over the primary any time soon.
• from the Guardian: Watch Elizabeth Warren blast Biden for his stance on abortion funding. biden drew a massive amount of criticism from democratic candidates over supporting the hyde amendment, probably the strongest of which came from elizabeth warren. in warren's words here: "We do not pass laws that take away that freedom from the women who are most vulnerable"
• from Jacobin: Elizabeth Warren Has a Plan for Everything — Except Health Care. jacobin has an article focusing on the conspicuous absence of an actual healthcare plan from all of warren's ideas so far in the campaign. warren has been pretty vague about what her healthcare policy actually is despite firmly falling into the progressive camp, and she's not really committing to anything in particular yet, to which jacobin encourages her supporters to press her. in their words:

The entire country is desperate for health care security, and Warren is in a position to argue intelligently and emotionally in support of a bold, progressive solution, just as she has for so many other important issues. Her voice can help the single-payer movement in a significant way. Together with Sanders, she could make Medicare for All an unambiguous and uncompromising demand of the progressive left in the 2020 campaign. The longer she stays silent, the weaker the Medicare for All movement becomes in the face of relentless attacks from right and center.

Kamala Harris

• from CNN: Kamala Harris rolls out proposal that would require states to prove abortion laws were constitutional. kamala harris has basically proposed a section 5 provision for abortion rights, which would create a standard where states or polities with a history of unconstitutionally restricting abortion rights would have to prove the constitutionality of their restrictions before they go into effect. this mirrors section 5 of the voting rights act, and would be implemented by harris if she becomes president.
• from NBC News: Kamala Harris ramps up in early primary states. harris has largely lagged behind other candidates, but seems to be finally kicking her campaign in the early states into full gear this week. harris has been relatively low-key with her scheduling so far, only attending around 50 events, but she seems to be intending to gradually pick up the pace, which is probably a good idea because she still has a name recognition problem.

Beto O'Rourke

• from Buzzfeed News: Beto O’Rourke Wants Term Limits For Congress And The Supreme Court. beto o'rourke wants to do a bunch of stuff, but in particular he seems to want to implement term limits for congress; he has a plan which would "limit members of Congress to serving 12 years and create 18-year Supreme Court terms."
• from the Texas Tribune: Beto O'Rourke's proposed election reforms seek to simplify voting registration, get big money out of politics. that plan is also part of a broader scheme to reform politics. the crux of his ideas revolve around elections, where he wants "a national transition to same-day voter registration and automatic voter registration when any citizen visits a government office, with pre-registration for 16- and 17-year-olds" along with "let[ting] people vote without ID as long as they sign a "sworn written statement of identity."" o'rourke wants to "mak[e] Election Day a federal holiday, expanding early voting to two full weeks before Election Day and relocating polling stations to more convenient places." o'rourke also wants to reform campaign finance, among other thing spporting "encouraging low-dollar donations by making contributions up to $500 tax-deductible and matching those donations with public funds" and "requir[ing] campaigns to disclose donations over $1,000 within 48 hours" among other things.
• from CBS News: Beto O'Rourke says Biden "absolutely wrong" on abortion stance. o'rourke was extensively interviewed by CBS News the other day, during which he also threw some criticism at biden for his bad stance on the hyde amendment:

"I hope Joe Biden rethinks his position on this issue," O'Rourke said. "Perhaps he doesn't have all the facts. Perhaps he doesn't understand who the Hyde Amendment hurts the most...lower income communities, communities of color. I would ask that he rethink his position on this."

Pete Buttigieg

• from Buzzfeed News: Pete Buttigieg’s Struggle To Win Over Latinos Could Limit His Rise In California. pete buttigieg is going to need to do a lot of things if he wants to win the nomination, and one of them is win over latinos who currently are not going to him in nearly the numbers he needs. in california in particular, the biggest state in the primary his bump in the polls is really being limited by his current lack of appeal to the latino community (to which he is trying to rectify things, but not necessarily doing the best job). he's made overtures toward the latino community, but he's still going to need to do a lot more than what he currrently has on the card if he wants to compete with them.
• from NBC News: Buttigieg's big accomplishment that he never mentions on the campaign trail. buttigieg incidentally has one proposal which might actually endear him to the latino community's undocumented members but which he has yet to really play up on the campaign trail. in south bend he organized a "Community Resident Card" program through a private organization and basically turned it into an acceptable form of ID accepted by most of the businesses and services in the city, which allowed undocumented immigrants in south bend to participate in life without having to worry about immigration services.

Jay Inslee

• from Reuters: Presidential hopeful Inslee unveils plan to reclaim U.S. leadership on climate issue. jay inslee not only has plans on climate change, he also has plans on how to make the US a leader on climate change internationally. according to reuters, inslee's plan on taking the reins internationally "ranges from rejoining the Paris Climate Agreement, an international accord to fight climate change that Trump opposes, to more ambitious ideas like overhauling U.S. trade and immigration policies to prioritize climate change, and blocking U.S. financing for foreign fossil fuel projects."
• from Buzzfeed News: Gov. Jay Inslee Says He Is Running For President To Do “Everything Humanly Possible” To Defeat Climate Change. buzzfeed interviewed jay inslee primarily on climate change here and he goes into a bit more detail about his campaign, but probably the most interesting thing about this interview is inslee's non climate policies, which he also goes into a bit here. (he does not want to change the law federally on sex work, leaving it up to the states, for example.)

Everybody else

• from TIME: [LONGFORM] Bernie Sanders Wants to Change America. But He May Have to Change Himself First. this longform piece from TIME focuses on the bernie sanders campaign and bernie himself, mostly in how his own successes in 2016 have so far been his worst enemy in 2020 because other candidates have come to emulate him. in many respects 2020 will probably be a campaign which sees bernie reinvent himself in ways that he didn't previously have to consider in 2016, when he was an upstart radical challenging hillary clinton and trying to push for radical positions that are now basically mainstream in the party because of him.
• from Vox: Cory Booker’s plan to fix the housing crisis and make renting affordable. cory booker has policy on fixing the housing crisis, and in summary it's: tax credits for renters, federal incentives for affordable housing, “baby bonds” as ways to make housing more affordable, protections for renters against evictions, and aid for the homeless.
• from Buzzfeed News: This Democratic Presidential Candidate Has A Sweeping Plan To Eliminate Lead Poisoning. the apparently nameless julian castro hasa plan to deal with lead poisoning in america, which is something that no other candidate has put forward before now. his plan is pretty straightforward:

He would ask Congress to allocate $5 billion per year for 10 years to replace lead pipes and address lead contamination in paint and soil “in areas of highest need,” as well as an additional $100 million per year toward preventing lead poisoning in children.
For people whose blood has high levels of lead, Castro’s plan includes provisions for treating lead poisoning under universal health care, mandatory lead testing for children under 2 years old, and “support services including counseling, tutoring, education on nutritional needs.”

• from RollCall: Think Kirsten Gillibrand has no chance? She’s heard that before — and won anyway. kirsten gillibrand might be well behind most of the frontrunners, but she's no stranger to longshot races. as this RollCall article notes, gillibrand's first big victory came in a district that was something of a longshot, and despite the expectation that gilibrand would lose. obviously a congressional race is not a presidential race, but we're also early and technically speaking, nobody is out of it yet.
• from the Guardian: 'For the NRA, the gig is up': Eric Swalwell on why gun control is a winning issue. from one perennial 1%er to another, we now turn to eric swalwell, who the guardian snagged an interview with on the issue of gun control, the topic which motivated his run. in his view gun control is a winning issue primarily because of the massive toll mass shootings have already wreaked on the country and the fact that most people support restrictions on guns.

Opinion

• from the Guardian: Want to defeat Trump? Attack Biden. this opinion piece by bhaskar sunkara echoes a similar refrain from a number of people, which is that biden is out of step with the party and needs to be halted because his policies essentially make him an empty suit.

Rationale: labels are a valuable way to receive and give feedback, so it would be useful to have more labels-related tools.

This topic deals with labels received by an ordinary user or given by an ordinary user from that user's point of view (as opposed to non-logged-in lurkers, other ordinary users, and users with elevated privileges).

While labels presently only apply to comments, these suggestions would apply to topic labels when they are implemented, and to other labellable content types should any appear.

The “Gilded” page—Issue 423

Suggestion 1. Users can filter their user pages for content labelled Exemplary.

Unlike all other suggestions, this also applies to users viewing other users' pages, and possibly even to lurkers viewing user pages.

I also suggest that users have an option to automatically expand the Exemplary messages when they see their own Exemplary content.

Other labels given TO the user

The common point is that it would help if users observe the feedback given to them by others via labels. In addition, this would prevent label misuse and abuse.

Suggestion 2. Users have an option to observe labels given to their own content along with the label counts.

Suggestion 2a. If comment vote counts remain generally hidden, users should still be able to see the vote counts for their own comments.

Suggestion 3. Users can filter their user pages for content labelled Malice (but, of course, they should not be able to see Malice messages).

Suggestion 4. Users can filter their user pages for content with any label (maybe with further options like All labels vs “Non-major” ones).

Edit: Suggestions 2, 3, and 4 might go with time lags. Namely, labels given to own content are only visible for content older than X minutes (X can be even 1440 or more) and to users with accounts older than Y days.

Labels given BY the user

Suggestion 5. Users have an option to automatically expand the label pane for the content they have already labelled.

Suggestion 6. Users can easily overview the content they labelled Exemplary. (This is basically the “Gilded” page in the other direction.) In addition, users can see the messages they provided when giving Exemplary labels.

Suggestion 7. Users can easily overview the content they labelled Malice. In addition, users can see the messages they provided when giving Malice labels.

P.S. These suggestions deal with the current labels, but they can be extended to future labels, e.g., group-specific ones.

It can be your favorite for any reason: interesting subject, extremely in depth and well written, funny details, “branching potential” (it links to a lot of interesting topics you can branch off to), etc.

The recent topic about vote counts being removed has sprung up some discussion about the nature of validation. Given that the comments over there seem to address the idea in the context of Tildes specifically, I figured I'd create an offshoot thread for a more philosophical discussion of the question at large.

• When is validation a good or bad thing?
• Is seeking validation fundamentally a bad thing?
• Is receiving validation for something great you've done fundamentally a good thing?
• What is your own relationship like with validation?
• Should platforms structurally encourage/discourage/balance methods for validation?
