I've been into Kamen Rider and Super Sentai for a few years and I'm wondering if there are any other fans on this site. (I was going to make this a general tokusatsu topic, but I'm not into Garo or Space Sheriff or, idk, Pretty Guardian Sailor Moon, so I wouldn't be able to contribute to discussions on them.)

Do you have a favorite installment of KR or Sentai? I'd have to say my fav Rider is W; the partner dynamic, and the detective noir style and subversions thereof, really tickled my fancy. For Sentai I guess my favorite was ToQger, but I feel kind of cheap saying that since it was the first series I saw all the way through; but I loved how silly and serious it was at the same time, and while I usually hate the kind of Red that ToQger had, Right had a really good reason for being that way.

Anyone watching Build and LuPat? I'm loving them both. Build feels like a shonen anime and I'm sure it's on purpose, and sometimes it makes me roll my eyes, but I like the characters and how they bounce off each other (even if Misora and Sawa could be given a bit more to do). LuPat is shaping up to be a really great Sentai; I can't wait for the two teams to inevitably team up, like we all know they're going to.

Anyway I'd really like to talk about these shows with anyone else who's a fan!

Whats this about?

@wanda-seldon started a thread over at ~science in hopes of generating more user created content. My plan is to post some introductions myself, in fields like mechanical engineering and automation (is anyone interested in it anyways?). But until I feel like I would do it proper, I figured I'd try something similar with a much lower barrier of entry. I'll write about some hobbies of mine, in a way that goes more indepth about the process, but still shallow enough to function as an introduction. And if folks are interested in more in-depth stuff or pointers on where to go, I'll take care of that.

So on todays topic, homebrewing. What is it, why would you bother, and what's actually involved in it?

What's Homebrewing?

Put simply, homebrewing is the art of making beer yourself. It's not really that complicated to be honest.

Why Homebrewing?

• It's (relatively) cheap.

If you got a few basic kitchen items (pots, ladle, cups, etc), you already have most items needed for brewing a small quantity. A few additional tools will be required, like a food grade plastic container, a water lock, etc. but if you treat them proper they can be used for years after years. Ingredient cost is neglible.

• Quality.

A common reaction many have with homebrewed beer is how thick and rich in flavour it is, compared to your average supermarket beer. Especially if your experience is with light beers (in which case I believe Monty Python said it best, it's fucking close to water). It's like comparing that sad pie you can buy in the cooler section, compared to something fresh out of the oven with the sweetest fruits and crispiest crust.

• Easy to learn, hard to master.

If your goal is to make a good beer, you only need two "skills". Good working hygiene and patience. Beyond that, any complication you want to add is up to you. You can start with a simple ale and work your way towards horribly complicated recipes that seem more like a chemistry exam than a hobby.

Whats actually involved in it?

So what do you actually do? I'll keep it short, even though I could write a book if I wanted to cover everything. Brewing is made out of three phases. The actual brewing, the fermenting and the bottling.

Brewing

You mix malts (and/or barley, wheat, oats, etc) with water, which you will draw a wort from. The wort will be the basis of your beer. A wort is a bit like a tea from a tea mix in this sense. Also it's sickly sweet (so taste test on your own risk). The sugar from the malt will be what is turned into alcohol during fermentation. In a similar way, that we use fruit sugar for wines/ciders or honey for mead.

Fun fact: In Sweden and Norway, elks drunk on rotten (fermented) fruit they eat from the ground is a rare but real phenomena.

Once you have a wort, the wort is boiled up and hops are supplied. Usually hops are divided in two categories. Bitter hops and aroma hops. Though that has more to do with when you add hops in the brewing process. The hops add flavour primarily from the oils (which give the fresh and fruity taste) and the resin (which gives the bitter taste). The resin takes a certain amount of boiling time to properly release, so hops added early in the process will contribute to bitterness.

The liquid is then cooled and stored in a container with a bit of yeast. That marks the start of the fermentation period.

Fermentation

Fermentation is fairly straight forward. Yeast loves sugar. And will keep eating it until most is gone. Alcohol, is a byproduct of this process.

Bottling

Once fermentation is (nearly) done, the beer is transferred into bottles. After a few days of waiting, a pressure should have built inside your bottles which will create the nice bubbliness we know from beers. Toss on a label if you wan't to brag and want to make sure that graphical designer education was not for naught.

Swell, how do I get into it?

How do you get into it? Technically speaking, you could start with no-mash brewing. Though I would recommend against it, as it takes out the charm of actually brewing, since you just add water and call it a day. Alternatively, there are several good sources on this. The american homebrewers association for instance have a good quick guide for some instructions. Though if you wan't to go serious about it, I recommend to read up on the specific processes, and what influences them.

Afterwords

Does it sound interesting? Bring a buddy, and make a day of it. Make your own labels too if you wan't to brag to friends and family. If you have questions, I will answer anything. Need help setting up or want a plan, I can help with that too.

Edit: Would recommend reading @piratepants comment in the comment section. It expands a lot of the things mentioned here, and goes a lot more into the actual processes while brewing. If you got this far, it's worth continueing.

On June 18th 2018, it was announced via StubHub's ticketing website that Rammstein would play songs at their Puerto Vallarta, Mexico show from their new album set for release later in 2018. These are the only two announced tour dates for them for 2018.

They haven't toured North America since 2012, other than the odd spot at festivals, and usually only do special shows in Europe at this point. I've seen them once before, and it was the best concert I've ever been to. But in order to see them I'd have to spend money on a ticket, plane ticket, and resort hotel so I'm extreeeemely torn on it. On the one hand, I don't know how many chances I have left to see them. On the other hand, it'll cost a lot of money.

What's the most you'd pay to see your alltime favourite band?

I added a bidet attachment.

Installation went fine.

When I tested the bidet, it kind of went like this...

I apologize in advance for what's probably going to be a very rambly post. This has been stewing on my mind for a while now and I just need to get it out.

I've been on reddit a long time, 11 years as of today in fact. In that time, I've watched the site grow from a small community of mostly tech nerds to one of the biggest sites on the web. I've also moderated many communities, from small niche subs (/r/thecure, /r/makeupaddictioncanada) to some of the biggest subs on the site (/r/worldnews, /r/gaming). I've modded communities that have exploded in popularity, growing from 25k to 100k to 500k and beyond, and seen how those communities change.

When you're in a subreddit of say, 10k users, there's more community engagement. You know the users, the users know the mods, and you know when people are engaging in good faith. The mods themselves are basically just another user with a bit more control. People coming in just to cause shit are generally downvoted to death and reported quickly, and taken care of - it's a community effort to keep things civil. Modding a community like that is piss easy, you can generally check every thread yourself and see any nastiness easily before it becomes a problem, and the users themselves are more invested in keeping things on topic and friendly. Disagreements are generally resolved amicably, and even when things get heated it's easy enough to bring things back to center.

Then the community starts to grow, and gather more users. Ok, you adjust, maybe add another mod or two, the users are still engaged and reporting threads regularly. Things stay more or less the same. The growth continues.

At 50k, 100k, 250k, etc you notice differences in the community. People argue more, and because the usernames they're arguing with aren't known to them, they become more vitriolic. Old regulars begin drifting away as they feel sidelined or just lose interest.

At 1M a major shift happens and the sub feels more like a free for all than a community. As a mod, you can't interact as much because there's more traffic. You stop being able to engage as much in the threads because you have to always be "on" and are now a representative of the mod team instead of a member of the community. Even if you've been there since day one, you're now a mod, and seen by some as "the enemy". Mods stifle free speech after all, removing posts and comments that don't fit the sub rules, banning users who are abusive or spammers. Those banned users start running to communities like SRC, decrying the abuse/bias/unfair treatment they've gotten at the hands of X sub mod team. Abusive modmails and PMs are fairly regular occurrences, and accusations of bias fly. The feeling of "us vs them" is amplified.

Once you get above 10M users, all bets are off. Threads hit /r/all regularly and attract participants from all over reddit. These threads can attract thousands of comments, coming at the rate of several hundred every minute. Individual monitoring of threads becomes impossible. Automod can handle some of it, but we all know automod can be slow, goes down sometimes, and can't handle all the nuances of actual conversation. You've outgrown any moderation tools reddit provides, and need to seek outside help. Customized bots become necessary - most large subreddits rely on outside tools like SentinelBot for spam detection, or snoonotes for tracking problem users. Harassment is a real problem - death threats, stalking, and doxxing are legitimate issues and hard to deal with. I won't even touch on the issues like CP, suicidal users, and all the other shit that comes along with modding communities this large.

I wish I had some solutions, but I really don't know what they are. We all know the tools we have as moderators on reddit are insufficient, but what people often overlook is why - the community is just too large for unpaid volunteers to moderate with the limited tools we have.

Hi everyone! In this challenge, we will build simple genetic algorithm.

The goal is to create genetic algorithm that will learn and output predefined text ("Hello World!").

The goal can be achieved with any language and you'll need just simple loops, collection and knowledge how to create and use objects, even beginners can try to complete this challenge.

How?

I'll try to explain it as best as I can. Genetic algorithms are approximation algorithms - they often do not find the best solution, but they can find very good solutions, fast. It's used when traditional algorithms are either way too slow, or they even don't exist. It's used to, for example, design antennas, or wind turbines. We will use it to write "Hello World".

First of all, we define our Entity. It is solution to given problem, it can be list of integers that describe antenna shape, decision tree, or string ("Hello World"). Each entity contains the solution (string solution) and fitness function. Fitness function says, how good our entity is. Our fitness function will return, how similar is entity solution text to "Hello World" string.

But how will the program work? First of all, we will create list of entities List<Entity>. We will make, for example, 1000 entities (randomly generated). Their Entity.solution will be randomized string of length 11 (because "Hello World" is 11 characters long).

Once we have these entities, we will repeat following steps, until the best entity has fitness == 1.0, or 100% similarity to target string.

First of all, we compute fitness function of all entities. Then, we will create empty list of entities of length 1000. Now, we will 1000-times pick two entities (probably weighted based on their fitness) and combine their strings. We will use the string to create new entity and we will add the new entity to the new list of entities.

Now, we delete old entities and replace them with entities we just made.

The last step is mutation - because what if no entity has the "W" character? We will never get our "Hello World". So we will go through every entity and change 5% (or whatever number you want) of characters in their solution to random characters.

We let it run for a while - and it is done!

So to sum up what we did:

entities <- 1000 random entities
while entities.best.fitness < 1:
  for every entity: compute fitness
  newEntities <- empty list
  1000-times:
    choose two entities from "entities", based on their fitness
    combine solutions of these entities and make newEntity
    newEntities.add(newEntity)
  for every entity: mutate // Randomly change parts of their strings

print(entities.best.solution) // Hello World!

Now go and create the best, fastest, and most pointless, genetic algorithm we've ever seen!

I don't watch a ton of TV, but one show I've binged lately has been Pose.

https://www.imdb.com/title/tt7562112/

The show is set in the ballroom scene of 80s NYC, and deals with a lot of hard topics like the HIV epidemic, gay and trans POC and their acceptance in the "straight" world, and what makes a family. It can be tough to watch in parts, and the first season's storyline was a bit too cliched in places. But overall it's a well acted, well scripted show that highlights a very unique part of history.

Has anyone else been watching? What did you think?

Currently it isn't too difficult to follow people and their posts. That will likely change as Tildes participation grows. I for one would appreciate a feature to follow individuals and their posts. I realize this is likely low on a priority list and since I'm relatively new, my apologies if this has been suggested before.

Thanks for all the hard work.

Every now and then we get a change in a traditional medium that has the potential to completely change the medium itself. In TV, we went from black and white to colour to 3D, and now to VR. In theatre, we've been seeing more use of screens, and other technologies.

In the last few years, Broadway saw two amazing game-changers - Hamilton, and Deaf West's revival of Spring Awakening. Hamilton, honestly needs its own post.

Deaf West, as their name suggests, casts deaf actors with other actors supplying their voices. American Sign Language is incorporated into the dialogue, songs and choreography. It adds a whole new dimension to existing works and allows the theatre medium to be enjoyed by a more inclusive audience.

I really hope to see productions like this more.

Thoughts? Anything new or old brought to theatre that you love? Any changes you'll like to see?

The short version is throughout my life I've seemed to be unable to execute sustained action towards any kind of meaningful forward momentum. I know very well all the things I need to be doing, but in that precious moment called the present things always seem to slip. I can't gain traction. All reagent and no catalyst.

It goes without saying that the irony isn't lost on me of asking for advice, more information, more data, when what's really needed is action, but I simply don't know what else to do.

The details;

I think by far my biggest character flaw so to speak is a lack of an ability to execute under normal circumstances. Obviously procrastination and other related behaviours plague most people to one degree or another but I think in my case it's at a point where it presents an arguably existential risk to any kind of real future.

I'm in my late twenties working a relatively low paying job with moderate technical skill. Like many other children in the 1990s I was diagnosed with ADHD and medicated, though with little to no success. I stopped in my late teens but have recently begun to experiment anew consulting with my family doctor. I've since failed to renew my latest prescription but I think there's some small potential there. That said I think the buik of the change will still have to come from within.

I'm reticent to frame my experience within the pathology of a medical condition and would prefer to describe my experience without the artifacts and assumptions I feel would otherwise flatten the anecdotes. For years now I've been meaning to study when I get home from work, go to the gym (hell, just get a subscription), eat healthier, etc. There's a burnt out light in my kitchen I've been wanting to change for the past 3 weeks and haven't gotten around to. Everything slips. If I remember I need to do something I'm walking to the grocery store, or on the bus to work, or at a friend's house. I've been meaning to return a friend's call for over a month. Again, everything slips.

I feel like I'm at a point where I really need discipline and this scares me. I dropped out of college 10 years ago, live alone and work full time. I have no academic backing to speak of and feel this severely limits my future prospects as far as both lucrative, enjoyable and fruitful future employment goes. They say that when trying to plot future human behaviour the best predictor by far is past behaviour; so I'm at a point where personal success is probably unlikely, so I'd also be content being in a position where I can positively impact the lives of others. I feel all else aside this should even be a priority; I need not necessarily find success or happiness if I can be some part of the catalyst for a multitude of people to find it. Net positive for the cosmos and all that.

I've got a relatively strong foundation of knowledge for doing IT work, having administered a handful of Linux desktops and servers for personal use for the past 5 years (with previous albeit inconsistent dabbling prior to that). I generally believe in open source software and try to use it wherever I can. Unless something Very Bad happens computers are going to be a huge part of the human experience moving forward and if we are to truly prosper for the coming millennia it's probably best if this part of humanity wasn't closed off in boxes held by duopolies with the power to rival governments.

In regard to IT work I also want to stress that I'm not kidding myself either, there would still be a lot of work to do in terms of certifications, an exponential increase in experience, etc. Dunning–Kruger looms its head here I think. Also, though it's probably my best asset to convert into a career I'm not sure I like the culture that surrounds IT at least as far as I imagine it, and I don't have a particular fascination with things like networking or server administration which has me a bit worried. For what it's worth I'd say my true passion lies in the Sciences, namely Astronomy. Fusion seems to be the main attraction in the Universe so I like to pay attention. Words fail me a bit here but suffice to say the latter is the only subject which I feel truly fascinates me.

The world isn't lack for the musings and moans of uncomfortable souls, and this turned out much more long-winded than I intended it to. I can't imagine anyone reading this to derive much value here so I'll cut it short.

If you've made it this far and have any kind of feedback I'd appreciate hearing it.

Cheers,

So after yet another round at the eye doctor yesterday, it seems my glasses prescription has been all wrong for some time (!?). I've been told I am/am not a candidate for LASIK. I've had whole diopters of change in prescription over six-month periods, An ""uncorrectable" astigmatism in one eye from an old orbital bone fracture has corrected itself suddenly (yay?).

What reading I've done suggests that the research basis for understanding the biological mechanisms of optics in the human eye and visual information processing in the brain, versus various styles of correction, is bogus (to put it mildly).

The incidence of severe myopia/astigmatism is rising dramatically around the world, not coincidentally with screen time, and it's getting more difficult to treat adequately. Anyone else feel like they're going blind slowly, and are there any evidence- or experience-based, reliable solutions you've found?
