There's a lot to dislike about Elon Musk (mostly related to his lack of filter) but he has founded multiple successful companies worth hundreds of billions of dollars each. It's possible he'll somehow make twitter worse than it is and starts hemorrhaging users, but if I had to choose I'd bet on Twitter ending up in a better place than it is now.
"In order to prove correctness you have to prove that the procedure gives the error bounds you claim"

You don't get to just add your own requirement for correctness and then force people to prove it?

They claim a specific thing - they prove that thing.
That thing suffices to prove that it succeeds at matrix multiplication. You for some reason really just don't like that as far as i can tell, and argue it doesn't suffice for usefulness (which i agree on)

Matrix multiplication, and "essentially any other numerical algorithm", is not defined in terms of the error bounds for correctness. That is just BS. The error bounds depend on implementation factors, and as such, they are totally unrelated to correctness.

Let's take a look:
https://en.wikipedia.org/wiki/Matrix_multiplication

I have read the entire definition, nowhere does it refer to error bounds as a requirement for successful matrix multiplication!

The word "error" does not even appear on the page

Since it's wikipedia, I also pulled out my college math books. Same thing.

They prove correctness without any reference to error bounds. Those are accepted proofs.

I don't see a single basic proof that has error bounds as part of correctness.

It, again, wouldn't make any sense, because error bounds depend on implementation factors.

So again, you simply can't add your requirement to correctness just because you like it. They still remain where they should be - usefulness for application.
And for electronics this is expensive, as I alluded to earlier. The guided artillery shells used in Ukraine now are actually more expensive than individual HiMars rockets.
Go on Alibaba and you will find that a surprising number of companies take BTC or USDT. The next step in the laundering process is fairly obvious.

>Bingo. I say this all the time, Twitter is not immune from being a member of this list (Defunct social networking sites, wikipedia):

It is if people who've decided it's "de facto infrastructure" get their way and the government nationalizes and regulates it. Then we're all stuck with it forever.
"And second, the numbers themselves aren’t stored there in plain text, but rather in the form of a hash code."

Very strange. There is no additional security by hashing phone numbers. Not that I trust anything form this source but anyway.
What indeed, what are you remarking on here? It's just one of a dozen easily used cross-platform UI frameworks, what's the problem? (and of course, "what's the problem for people on modern computers for which even small games are 500Mb these days", electron's not being used to distribute a web app that's 50x smaller than the UI framework itself in this case)
Everybody sucks at memorizing unique passwords. I'd be stunned if homeless people are consistently not reusing passwords. Credential stuffing is the #1 form of account takeover and 2FA is the solution.
For live video, bandwidth is a killer. If you have volume and do an upfront committment you can negotiate down to < .01/GB and below.

It's crazy how much people make off of bandwidth. From what I understand, that and RAM are huge margin products for AWS.

Also, you need to do the "get three quotes" thing. Akamai, fastly, and AWS will match/beat each other if you ask.
Yeah, but meth is illegal. Selling a 3D printed gun in the US is more like trying to sell skunk weed in a place where dispensaries are on every corner.

I think the best evidence that criminals don’t want 3D printed guns is that they already exist, and criminals aren’t using them.

The advantage of 3D printers is ease of retooling compared to traditional methods. This is why they’re good for prototyping, but not good for mass production. Mass production techniques will always produce better quality/cost balance due to the nature of the processes. The advantage of 3D printing provides no utility to a criminal gun dealer.

In places with strict gun control, the guns crimes that happen still rarely use 3D printed guns. Basic metalworking tools are also inexpensive and are a better fit for the purpose.

>“You want to know what this [war on drugs] was really all about? The Nixon campaign in 1968, and the Nixon White House after that, had two enemies: the antiwar left and black people. You understand what I’m saying?

That's a very popular quote, but it's not as slam dunk as you think. The veracity of the quote has been challenged. It was allegedly obtained 26 years after the nixon campaign, and was only published 22 years after that.

I think it comes down to identity. There’s no conflict to believe Russiagate was fake and that Trump lost the election. But people treat politics like team sports and chose their “teams” position on matters.
Sabine Hossenfelder about Nuclear Power
"What speaks in favor of nuclear energy is that it’s climate friendly, has a small land use, and creates power on demand."

"What speaks against it is that it’s expensive and ultimately not renewable."
...which is certainly before the heat death of the universe.
I first went to college in 2002 intending to pursue an engineering degree. At some point before I started school my dad (who had learned programming in the 90s but never did it professional) told me he thought I'd enjoy a programming career and I should think about switching majors. I dismissed it as teenagers tend to do with their parent's advice. Ended up dropping out of school and drifting through my 20s without much to show for it because I didn't know what I wanted to do. It wasn't until 2012 that I went back to school for CS. Can't help but think about how different things might be if I'd gone into the "right" major from the start and entered the industry making a decent salary 8-9 years earlier. But realistically I was a very different person 20 years ago, and just changing my college major probably wouldn't have fixed the things that prevented me from being successful the first time around.
> I'm personally very opposed to forcing them to trust, to ramming the truth down their throat. Instead what I would prefer is that these people are given the tools to find the truth on their own.

But they think they've already done this. They used the Tools That The Ivory Tower Elites Hate like YouTube and Facebook, found the extreme crackpot content, and convinced themselves that with these tools they have finally found the truth that those nasty authority figures have been trying to hide from them!

I'm no sysadmin so my knowledge in the field is limited. I'm relying on ZFS mirrors which hopefully should be a bit better than the alternatives at bit rot protection, but admittedly if I was hit by corruption at that level that would catch me unprepared. I'm open to suggestions however.
> I personally believe the best managers are those who have been at the front line and work their way up. They know the business from bottom-up and know how to treat people at each layer.

I've seen good and bad managers come from both paths. The problem with the MBA and no experience path has been well tread in this thread, so I'll touch on the other a bit. The problem there is that often people who work their way up are promoted into management for reasons that are completely ancillary to their potential skill as a manager. Management is it's own skill and just because you were a really high performer as an individual contributor doesn't mean you'll be good at management. These are actually some of the worst managers I've ever seen. They also tend to lack the sort of broader business and strategy knowledge needed to really succeed in upper level management.

As an example, I have worked with hospitals a lot as an analyst and my wife is a nurse. Hospitals are almost without exception the most poorly administered organizations I've ever experienced. Part of this is there are a lot of MHA and MPHs in upper management who've never spent a single day on the floor, but it's also because a lot of the management are people who got promoted not because they might be good managers but because they were outstanding nurses or Doctors or whatever else, and these people often make really bad managers.

What organizations really should do is similar to what the military does. Have your potential managers take on small assignments and then if they show promise you send them for additional training and education, have them serve on the staff of higher level officers, etc. But this is expensive and it's an investment in training that most businesses are unwilling to make.

tl;dr. "too cheap to meter" is just a well-known turn of phrase to point to the fact that nuclear is inherently affordable over time if you control for certain factors.

i acknowledged in my comment that "too cheap to meter" isn't a realistic expectation for a modern plant, and made the point that nuclear can be _more affordable than it is now_. for further technical reading you can start with https://world-nuclear.org/our-association/publications/onlin...

> beyond consuming an album at a time

That's the other thing I realized - I love finding great albums of music rather than individual tracks. Concept albums are especially great.
and thus does the problem continue because those who could help are too busy making themselves feel better with as little effort as possible.

I am someone for whom the two universes are the same. I freely choose to act exactly in accordance with how I would act if I were steered by neurons and atoms, and neurons and atoms alone. And that is also the truth, so I am perfectly happy. The universe with and without free will, to me, is metaphysically identical - because of how I have chosen to live and be happy.
Clearly the actual digits used in constructing a standard sudoku puzzle are of absolutely no importance.

Transpose some (or all) of the numbers, but leave the exact same shown+hidden squares, and your puzzle has not changed in the slightest.

You can replace the digits with dingbat font characters and you would have the exact same puzzle with regards to actually solving the puzzle.

So it seems obvious that this conversation comes down to the unique (post symmetry de-dupe) combinations of shown+hidden squares.

Additionally, there can be a discussion on which combinations of shown+hidden squares may actually be fun for humans to work on.
It's too late to change the outcome now. We're all screwed!

I used to have a large CD collection. I bought them and I sold them. I bought second-hand and new. It was fantastic.

And then one day I moved overseas and one of my CD boxes got lost in the mail.

And then, some other day, the bottom box of my CD boxes that were temporarily stored in a basement got flooded and destroyed.

Now I don't give a shit about CDs. I have unapologetically pirated the music from CDs that I used to own but got lost or destroyed, and for all my new music I bought it online and back up the digital files to the cloud. I'll never lose music I paid for again.

CDs are legacy media for a reason. All other legacy digital media will follow it, except for the small group of people who fetishize it for nostalgic reasons. There is a tiny argument that still exists for buying legacy analog media - the "it sounds warmer" argument. But honestly, you could just pipe your digital files through a filter and get the same effect, so, meh.

Music theory is an approximation of what the aggregate human preference function for music is, where the aggregate is over a region and time. It's not really a theory per se, but you could definite "learn" many aspects of theory from enough labelled examples. Given many western music examples, you would easily learn circle of fifths and other common details; given indian music, you would learn microtones and other subtle touches that make indian music have depth.
Playing as a dance/cover band as they did (compared to, say, classical music), they had plenty of space to experiment. The critical aspect that's different from practicing with your band in a rehearsal space vs on stage is that you get to see how an audience actually responds to what you're doing, which is the whole point of the game. Every audience is different. A musician who's played 100 sets of songs alone in a room will have nowhere near the same level of insight as a musician who's played the same number of shows for an audience.

As an instrumentalist, I can choose to play my part ahead of the beat, behind the beat, right on time, I can choose to embellish my part or play it as written, I can improvise a solo vs play something pre-planned, I can subtly vary the intensity of my playing, all while my bandmates are tweaking their performance in real time, too. There's also the telepathy you tend to develop with your bandmates when you're unable to stop a show and yell about mistakes or forgotten parts :)

And then in alternative-universe HN people are complaining about the rate of account takeovers via credential stuffing and calling Google irresponsible for making it easy to disable a powerful security measure.

> You can encourage 2FA but forcibly enabling it for everyone does more harm than good

I'd wager that pretty much the only people on the planet who can definitively say this are the people who handle account takeovers and lockouts of large email services. My understanding is that the folks at Google responsible for this have concluded that making it behave the way it currently does is the setup that causes the fewest people to lose access to their accounts.
I don't think it's about money. Software engineer salaries are very high, and cubicles are a compromise that still saves space. I think it's because for most people, procrastination reduces output a lot more than distraction and noise, and they procrastinate less when everyone can see their screen.

Great article about a very inspiring person. I particularly like this quote about an important skill to develop:

You should be fighting this at the school. Wikipedia should not be used as a source for academic purposes; the sources being referenced on Wikipedia very well could be though and as such Wikipedia is an incredibly useful tool for surface level research and schools should absolutely be taking this approach to using it.

They should not, under any circumstance, have children "Googling" the answer to questions. Most of these kids parents already use that phrase as a keystone of their parental pedagogy and they don't need that in school, too.

Wikipedia is wonderful. They have more money then they will ever need so don't donate; but, they are great. Everyone should have a copy of Wikipedia locally updated yearly.

If only Signal found a way to keep the desktop app linked for more than 30 days. There have been a series of FRs that constantly get ignored and "you're using it wrong" from the developers.

Thankfully the one friend that was using Signal finally gave up on it since everybody else was always missing his messages, so I no longer have to re-link every single computer every time I use the app. (with a 30 day expiry and 3 computers, it meant virtually 100% of the time I tried to use the desktop app I had to relink to my phone).
I am kind of annoyed that I am just now learning about how mainframes are designed in 2022, at a time when it is IMPOSSIBLE to dip a toe into the water without already having a job doing the work.

No free developer OS distributions or licenses, (so no way to run them on an emulator), no freely available emulators for modern hardware & OS releases, nothing.

Mainframe vendors, I feel, are kind of shooting themselves in the foot with this "screw the developers, they gotta PAY" mentality around this insanely expensive mainframe kit. How am I ever to learn this stuff well enough to advocate for it at work, if I can't use it and learn it in my own time? This feels like step 0 in trying to bring users to a platform, dying or not.

This article and others all show that a lot of the capabilities and redundancy requirements that we are trying to develop in PC architectures (amd64, arm64 & RISCV; are there more?) have been present in mainframes for decades, and that's an exciting thing to learn, not just because I want to write software that runs on reliable hardware, but because as a nerd this is... like ...TURBO interesting!

IBM and HP just block any newbies from doing anything of value because they're stuck in 1960s & 1970s pricing paradigms back when mainframes were all there was, so you HAD to pay if you wanted to compute at scale.

This whole situation bothers me. This is very neat technology and it's behind a massive paywall that no end-user could ever afford without a very large windfall.

> I’m looking into security/osint.

If you can breathe, spell cybersecurity, and have decent grooming standards, you can get hired in security. The 3rd is technically optional...

Get training, then take a crappy SOC level 1 analyst job to get exposure and experience - the hiring standards aren't a lot higher than your average call center at a lot of them, as we have a ~1.5M headcount gap in the industry. You will burn out or move up in 9-12 months just like all the other L1s, but you will either figure out it's not for you or you'll be able to get a foot on the next rung of the ladder.

Oh, I'd buy that in a heartbeat. SAL is, shall we say, most useful in the presence of non-public tooling, and it's also in general a fairly awkward language extension. Doesn't surprise me at all to hear that third-party devs haven't taken it up.

Not really. His promise was to build the wall AND make Mexico pay for it.

At one point congress agreed to give him almost $6 Billion to build the wall and he turned it down, never to be in that position again. If he wanted to build the wall he could have accepted that $6 billion or negotiated in good faith.

Also, his desire to build the wall was never a principled argument. "Build the wall and make Mexico pay for it" tested well with his audience so his campaign jumped on it (which was smart).

But to act like it wasn't strategic politicking from the beginning is not correct. Not to say that Biden's pardons are not politicking (they are). Just saying Trump and Biden are the same (and every other politician) when it comes to things like this.
A bit of a retorical question but isn't this a common source of contention between groups of people (across magnitudes of scale and means of information) throughout history?
I just think functional based program is a bit harder to reason about for newbies. Programming did not click for me until the third class in the track where we learned object oriented design. Pretty common experience in the program as well, scared away a lot of people who took fundies 1 to explore the major or to minor in CS.

Not exactly what you're saying, but made me think of a time when once, in a guitar shop, the clerk was playing really cool sounds on the guitar. She was playing in Hawaiian Slack-Key tuning [0]. She said Europeans had left behind guitars after "discovering" the islands. The natives then developed their own way of tuning and playing them, outside of the European styles. Here's a random link to a song in the style I'm talking about [1].
