Comment on All five people on Titan sub dead after 'catastrophic implosion' in ~transport

I think so... I don't think the implosion happened at disconnect though. Does anyone know if these vehicles tend to have black boxes? The logs could tell us a lot...
Later Thursday, the Wall Street Journal reported that the US Navy, using a top-secret listening system, actually heard the sound of an implosion hours after the sub went missing and that officials had thought it could have been the Titan.
https://news.yahoo.com/robert-ballard-discovered-titanic-wreck-163319516.html
Napkin math: NY to Paris is 3625mi. Sound travels in water at 1500m/s or ~3350mph, so if they heard the sound hours after the sub went missing, that implies a period of time from disconnect to implosion.
In that case, I'm curious to know why they couldn't abort the mission and return to the surface. Were they hoping for communication to reestablish? There's no way they continued the expedition after disconnecting, right? Were they returning to the surface already? Were there multiple independent or cascading failures, the first of which got them stuck?

On Reddit, one view would have bubbled to the top while mine would have been downvoted to oblivion and never seen.
Tildes encourages diversity of thought while Reddit creates echochambers, and the #1 reason why I think has to do with the lack of a downvote button hiding the minority and middle-ground opinions.

I'm more worried about eventual astroturfing. Tildes needs to grow 1000x for that to be a problem though.

Comment on Tesla’s “self-driving” system never should have been allowed on the road in ~transport

I get people don't like hearing this, but... this article is over ~17 deaths since 2021 (2 years!) when ~43000 people die annually of car crashes within the US. It's peanuts. If you believe autonomy saves lives in the long-run, then the question is how do we get to autonomy and is doing so worth it. I don't think autonomy can be reached without true miles driven at scale, so I don't see a great alternative. And I do see evidence the approach is working and AV companies are greatly improving performance over time... as the saying goes, let's not let perfect be the enemy of good.
Anyways, this article is flawed for a few reasons:
- It divides the numerator "cumulative fatalities encountered by Autopilot + FSD since from sometime 2021 to mid-2023" (17 fatalities) by denominator "total miles driven by FSD since ~2021" (150m miles). The numerator doesn't match the denominator.
To explain: Autopilot is shipped standard in all Tesla vehicles. FSD is a $15000 upgrade and has a low ~8% take-rate. That low take-rate cannot simply be multiplied against Autopilot's miles driven, because the systems have different use-cases (e.g. ability to turn on a street) and FSD has not been available for all its purchasers until recently.
So, we don't have a great denominator. We can find a lower-bound: In 2020 AP had 5 billion km driven, up to 50 billion km by mid-2022 ((source)[https://thedriven.io/2023/01/16/the-rise-of-the-machines-tesla-drives-50km-autonomously-through-heavy-la-traffic/]). Handwaving, that's a denominator of 45 billion kilometers, or 28 billion miles.
Note 28b is a factor of ~20 off from 150m.
Dividing 17 fatalities by 28 billion miles gets us a fatal accident rate of autopilot of 0.0607 deaths per 100 million miles, compared to the NHTSA rate of 1.35 or the article's claimed 11.3. Now both the numerators and denominators match, relatively.
So, doing the math 'more correctly-ish', we would get an upper bound accident rate that far less than the overall fatal accident rate as reported by the NHTSA...
Except this is still comparing "miles within autopilot including 5 seconds after disengagement" as compared to "total miles driven by non-autopilot cars" which is definitely still apples-to-oranges, as regular drivers do not use autopilot for all driving.
And once again, this comparison is about autopilot+human+Tesla vs regular humans in other cars. FSD expands to more use-cases and is a total rewrite of the system that is far more beta. Other cars includes older cars which might not have great active safety mechanics. Tesla also has the advantage of an instantaneous induction/PM motor. There are so many confounding factors that make it more than "is AP/FSD good or bad"...
-
The article cites MKBHD's video where FSD supposedly struggles on the highway. On Marques's build, FSD was not running on the highway; the 5-year-old Autopilot stack was running. Older builds of FSD, switched back to legacy autopilot nearing highways.
-
The article makes numerous other broken comparisons, e.g. making a large claim that Teslas account for 91% of self-driving crashes in NHTSA data implying that Teslas are then radically more unsafe. Teslas are also, somewhere around 91% of the fleet in terms of miles driven, give or take a few %. What's the point? Is there a real claim here?
(Full Disclosure: I have a financial stake in TSLA)

You felt an affinity with others in your community because you were all in on that secret, tiny little place on the internet that meant the world to all of you, and because communities were so small you almost had this pseudo-proximity with others that forced you to create bonds.
If someone had a website, that was really cool, as was building tiny websites together for your small group of 20 people to call home... There was a culture of sharing and excitement over what the future would bring... and the landscape was constantly evolving to meet that hype.
I miss the smaller gaming communities and guilds - the ability to find a small tribe of 20 and have that be big enough. They're not so much a thing anymore, and no big company's trust & safety policies will allow that to happen.
Big companies want infinite growth, and with that, their communities also tend to be pushed towards infinite growth... many discord communities have no business being so big, to the point where they become completely unusable PR arms more than anything. The faceless feeling of Reddit very much parallels the faceless feeling of matchmaking, where your opponents might as well be bots (and in the case of many mobile games, actually probably are bots masquerading as real users!).

They'd become the last few tech-related subs I followed, after the other tech subs got too large & started becoming really ignorant... but even they were getting worse over time due to tribal politics and the stock's movement drawing in day-traders and gamblers.
I definitely wish there were parallel subs for other topics, but honestly few other things attract the interest of geeks. What I liked about them was that they gave me a constant perspective of how applied technology was gradually changing the world we lived in + a sense of where the world will be in 5-10 years. Unlike, say, futurology, these predictions were generally somewhat grounded in reality rather than wishful nonsensical scifi, even if frequently missing the timeline by a decade or so.

/r/popular is full of banal memes as always. The news/politics subs are still up... their power-mods are extremely power-hungry, which I've unfortunately experienced firsthand modding alongside them. WhitePeopleTwitter stayed up, which is about what I expected from a mod team running that garbage.
My 8 multireddits are completely barren. /r/games stayed up, but technology and programming (which has reddit admins as top-mods) went down. Even truereddit went down after the community flamed the mods for thinking of keeping it up. The only subs remaining are pretty much corporate-owned (e.g. /r/unity3d, /r/leagueoflegends... having inside information I know 100% the mods there are in cahoots with real employees and get the occasional
bribesgifts and favors... oh, and that their mod team has overlap with /r/news which is up). -
Comment on Experiences with emotions (do you feel them often, and how to feel more emotions?) in ~talk

Your point on "resolving the situation at hand" absolutely resonates with me. I debug code for a living; if others experience bugs, then it's reflexive for me to try to patch that, so I need to fight against that.
Likewise, if I have a mathematical equation I'm stuck on, it is difficult for me to get it out of my head until it's solved, even if I'm out and about doing social things. It takes intentional effort for me to be "in the moment". I have a dog and he keeps me in the moment. Also, I'm not encouraging it since it's highly personal, but my first experience with weed also forced me into an extreme where I could only be in the moment, which revealed a new side of me that I could now self-analyze and blend into my regular personality.
If I'm upset after a fight or something along those lines, I'm pretty much a mute until I've "solved" the issue and I'm ready to move on ... which is not a great trait in a partnership as you can imagine
My other half is like that. She's has remarked that she can be "hard to love" because of this, so I understand what you're going through and have been on the other side. When we argue, she often clams up for the day and is incapable of dropping things and moving on, whereas I'm good at shelving fights and going on to do the next thing. I sorta get it... it's not so different from my math-solving fixation that I described above.
I don't think it's bad. I think it's different, but part of a successful partnership is about building on top of each others' strengths and differences. The strength here is that you want to be logical about your argument and work towards the precise logical outcome that would make you happy. This is a strength over others who might not so thoroughly process their feelings to understand their emotions.
Our workaround has been to use "10 minute rules", where we take a break to gather our thoughts and maybe write them down. We occasionally put off discussions to another day as well, to remove the immediacy of an argument and give ourselves time to process our thoughts.
emotional intelligence
I absolutely hate this term. I get it's well intentioned, but it negatively implies a deficit or stupidity and probably puts people on the defensive. You are clearly intelligent, you just struggle to feel as others do at times.
For the longest of time, I did not accept how I thought. My brain worked one way, but I was trying to get it to work another way (to be more intelligent). That was counterproductive.
My personal approach has moved towards 1. mirroring others through active listening (which takes time to do correctly without being really awkward, but eventually feels natural and passive) and 2. opening up with others on how I struggle to grok things sometimes, and probing to better understand their emotions.
#1 - active listening can actually be a really logical process. It's ultimately about trying to understand what others are saying and ensure they understand you understand them.
I feel #2 actually works quite well when done naturally - most conversations involve people wanting to talk about themselves, so it invites others to further express how they feel. And it gradually taught me to understand how others feel through my logical brain.
And yeah, occasionally people find #2 awkward, but it's no more awkward than being silent or not understanding (at which point people think you're not even listening to, engaging with, or interested in them). The expected value of the action is just better.

Why do you care?
Some notes from my struggles with feeling emotions and giving/receiving empathy. I feel similar to you in that I see:
-
Hedging at the start of your post, in case you're too different + logical thinking.
-
The feeling that you lack emotion, when your post is littered with emotion (anxiety, annoyance, curiosity, desire)
Part 1: Mismatching emotions
As a younger kid, I was often called "robot [miyu]" by my peers, spoken with monotonic voices and the occasional poor rendition of the dance. That bothered me because I felt singled-out as different, and the feeling of difference felt isolating.
I similarly panicked about why I lacked emotions. My school had a robotics program, and where others saw excitement in building an animated, lively being, I saw gorgeous cold metal and the product of our young team's unity. While others cried over graduation, I felt I was starting yet another summer before transferring to yet another school. I worried whether this meant I was a sociopath incapable of bonding with others. I'd occasionally think "maybe a psychadelic would fix me".
But I was feeling emotions; the above paragraph describes panic, the love of community and belonging, fear, and, sure, indifference/apathy. Those emotions simply didn't match those of others, and I got flak for that (as young people who don't know what they're doing do to each other), causing me to write off myself. I could speak to what I felt, but I couldn't feel what others felt.
So, my emotions were simply different than others'. That didn't mean I lacked emotions.
Part 2: A struggle with empathy.
Where I do struggle is empathy, which in young people terms is basically your ability to vibe with people while reflecting on something deep. I sucked at that in college. My brain's super logical, and there's frankly no getting away from that, and it's definitely a bit isolating at times. But I really can't find a logical reason to worry about changing things - in the past, I'd figure my logicalness was the reason of, say, isolation, but then objectively there'd been many moments in life where I wasn't isolated, so perhaps that wasn't a great excuse :)
Anyways, I see two parts to empathy: 1. input and 2. output. On the receiving side of emotions, I struggled early on because I generally tried to diagnose and problem-solve others' feelings, rather than simply giving others space to express themselves. On the output-side, I was so logical that I had a speech impediment that stopped me from sharing my emotions with others; I'd frequently freeze mid-sentence for 30 seconds, overly self-analyzing my words to avoid misspeaking.
I pretty much solved #2 by pre-writing statements (to get the long freezes and decision paralysis out of the way) for the first time. In time, I could naturally answer questions comfortably, without canning responses. Additionally, I gradually realized nothing I fixated on really mattered, so I could give less of a shit more often :)
Also a fun final 2c: for people like me, it was hard to find romantic partners because I was so unlike others online. The landscape nowadays is far easier - there are many dating apps that are much more focused on finding others with shared interests, rather than just vibing with others :) My other half is far more logical than I am, somehow, and that can be really funny!

There is certainly crossfire in those scenarios, but simply not enough time for moderators to sift through the BS to dish out unbans.
In 2020 we had a very blunt top-mod decree, that I half understand but find extremely unhealthy: opinions aren't changed; politics is about your side out-mobilizing the other side, not converting those who disagree with you. Ban liberally.
There are certainly a lot of situations where people cry wolf, and then there are communities they are legitimately heavily censored to create political forces shaped by their moderators.

I'm not a huge fan of Dash Berlin's latest work (in the end? why?), but I liked Mangoo's comeback a few years back as a throwback (eurodance) & still listen to Gareth Emery's hits from ~2015. Solarstone and A&F are definitely good guilty pleasures haha.
I've mostly been listening to chillstep and instrumentals, as rare as they may be. I feel they connect me best to what trance was. Huge fan of Mitis, Feint, and Blackmill. That plus I still tune into remixes of older songs as they're released. They're 90% not matches for me, but occasionally there's one that isn't to me a rave-ify of a gorgeous melody =)

"He who would learn to fly one day must first learn to stand and walk and run and climb and dance; one cannot fly into flying." - Friedrich Nietzsche
Focus not on finding a job, but building the skills necessary for you to succeed in one.
Make sure you understand the difference between programming, software engineering, computer science, TCS, and computer engineering. A professional has their place amongst these broad crafts, so understanding their differences will help you define your path.
If you haven't already, skim the slides of CS courses from S-tier universities. You can skim the contents of most engineering courses in a few days - if you retain even 30%, that's far better than the 0 you'd often have had prior. Begin with the intro classes, whose slides are meant for students who have less experience than you, who will comprehend their contents and succeed in their classes, so this is well within your means. Following, you will have the prerequisite knowledge to succeed in further classes (use the school's course dependency graph).
If you're struggling with side-projects, these universities' homeworks are frequently 1. somewhat interesting and 2. bite-sized (so you can finish a project!) and 3. insightful and extensible. By getting through a CS curriculum - which I think can be skimmed with at least 30%-50% understanding by most, mostly requiring tenacity, you will get a broader understanding of the problem areas faced in the broader discipline. The saying goes, when you only have a hammer, everything looks like a nail; so this is a fast way to discover what other tools exist.
Googling "California CMF" led me to a clearly biased article with text like:
Clearly that's talking past the point of opposition in bad faith, since I have a hard time believing many educators are actually opposing a framework because it favors equality or opportunity for all...
Diving further, I ran across this site by Brian Conrad, Professor of Mathematics and Director of Undergraduate Studies in Math, Stanford University: https://sites.google.com/view/publiccommentsonthecmf/ with gems like:
Anyway, personal opinions: a course on data literacy sounds great and is more applicable to real-life than algebra. California / the US don't let children specialize, which leads to these weird either-or situations; if you're pursuing certain subfields of STEM, you need a strong grasp of calculus, linear algebra, and differential equations to understand many basic concepts from first principles. For other subfields and non-STEM fields, there's effectively zero benefit to learning calculus and something like data literacy is far more valuable (e.g. how to interpret data and detect misleading conclusions). There shouldn't be one track for all students, and if perhaps there isn't time to teach these valuable concepts to students, we need to reevaluate the entire structure of education, not mess up math in isolation.
