I am very curious to see how this is going to impact STEM education. Such a big part of an engineer's education happens informally by asking peers, teachers, and strangers questions. Different groups are more or less likely to do that consistently (e.g. https://journals.asm.org/doi/10.1128/jmbe.00100-21), and it can impact their progress. I've learned most from publicly asking "dumb" questions.

Given the HN exposure, feels like a huge missed opportunity to write anywhere in the article what FLUX even is and what it's for. A single sentence would help so much. The way it's written, you can read the entire thing and still have no clue.

Is being constant online killing my productivity?
Hi, I am a 34 years old guy with ADHD. I remember times in late 90s and early 2000s when I haven't got access to the Internet. I was a young boy then who loved to tinker with computers - knowing every part of the UI of Windows 98 and playing around. Back then I used to be creative and able to do cool stuff on my computer. Right now I have a feeling that my attention and focus got stolen everytime I need to check something online. I know that the modern social media and Internet in general is designed that way. And I know the mechanism but got tricked anyway. Does anybody now have a computer with limited access to the internet or have a completely offline machine? I wonder how I can trick myself to be productive again. FOMO and content consuming is destroying my brain and I would like to be that curious child again that makes things. How do you tackle this issues?
BBSes were a very big part of my early computer days. I learned real programming in high school teaching myself and hacking on BBS source code in Pascal. Not knowing that I would soon be on the Internet, one of the reasons I went to university in a city was so that there would be local BBSes. All of that had huge impact on my life and I’m just one small example. I and many others owe huge thanks to Ward Christensen and all those who carried on what he started.
Let's say he can do two such jobs per day and has 50% overhead. That puts his hourly rate at $700/4/2 = $88. That's good money, but it's probably less than what you make.

Oh wow, really? Even if you feed it whole research papers? The ones I tried until now were more in the 8-10 minute range. I haven’t looked in to how to control the output yet. Hopefully that’ll get a little more transparent and controllable soon.
It's a somewhat difficult issue and I understand being hesitant because of this. Converting to SVG is one possible path around it which isn't too bad but having it natively is of course even better.

The thing is, inserting PDF for just the PDF export would be quite easy. The issue is the other export targets Typst supports (SVG and PNG) as that would require some form of rasterization / a full blown PDF engine written in Rust without C-bindings because of the web app and that simply does not exist yet.

And the developers are hesitant to just add features for one specific export target which I get.
That's really interesting -- I do enjoy a good optimisation.

I was looking at one of the diffs, and thinking at a sufficiently advanced compiler should be able to generate the same efficient code for both -- and indeed it does, if you turn the optimiser on: https://godbolt.org/z/hjP5qjabz

Those are all complaints about bottom-tier American food. A good cheeseburger from a local place is mindblowing. I had one with peanut butter on it last week; we still eat allergens but they have to be labeled. Mexican Coke is way better, true. You're talking about Hershey's chocolate bars which no one considers to be "the good stuff".

If you're looking at McDonald's and saying American food sucks, you're missing a whole hell of a lot.

There've been a lot of studies and meta studies on correlation between cellphone usage and academic performance.
IIRC the Pearson correlation coefficient for that has always been hilariously low. Something like -0.1 to -0.2.

The argument these days is more about "distraction" caused by cellphone usage instead of something quantitative.

IEEE 754-2019 says for the transcendental functions (the ones in §9.2):

> A conforming operation shall return results correctly rounded for the applicable rounding direction for all operands in its domain.

so all of them are supposed to be correctly rounded. I think IEEE 754-2008 also requires correct rounding, but I don't have that spec in front of me right now.

In practice, they're not correctly rounded--the C specification explicitly disclaims the need for them to be (§F.3¶20), reserving the cr_ prefix for future mandatory correctly-rounded variants.

i don't think i've done a bait and switch and generally don't actually know what you mean by saying that i have done so. my point in that sentence was simply that nothing is promised by life. society does have norms and people do have values. i never said that i don't understand (nor did i intend to imply or portray that i don't) why people would act in ways that are not to, or hurt, "the common good". it is clear why someone who doesn't feel like their life is comfortable when they are trying to better "the common good" would act against that same common good in order to get some peace or enjoyment out of their own existence.

All Humans believe the bogus, doing otherwise is not possible.

I've yet to meet a Human for whom down the curve of their position is not ~idiocy, and up the curve is not ~pedantry (or something invalidating of a more absolute view on things).

As long as the only serious problem is those other people, I think we remain trapped in this local maxima.
It takes time (plus money) to drive all over the place giving quotes for simple jobs that people end up getting multiple bids for and/or end up not hiring anyone in the end. Those costs aren't provided as charity, but rather has to be baked into the price of the jobs that do get accepted.
I used to think that once I started browsing the internet, it was time for a break. One technique I've implemented, which I haven't seen mentioned is "walking pomodoro technique": for every 25 minutes of work, I get up and take a brisk 5-min walk (or lately, a jog) and come back. One of the most surprising things is that by mandating my own breaks, I browse the internet a lot less.
Here's my hot take: conspiracy theories and outlandish myths are America's version of Old World superstition and folklore.

Study any European culture and how it was Christianized, and how the local culture, folklore, and mythology melded with religion to become a unique tapestry. Look at Ireland for a really pronounced example. Look at the folktales and revered fables that came out of those cultures for a synthesis of what rural folk really believed and talked about over dinner, and by the hearth in the evening times after work was done.

But the United States has none of that. The New World came of age during the Enlightenment era of reason and rationality. Now we're in a post-Christian society, one rooted in science and empiricism, but we're still yearning for the supernatural, and it's manifesting in unique ways for us. Americans don't have faeries or unicorns or goblins, we've got chemtrails and little green men. Furthermore, as the U.S. and other New World cultures progress, we're making our own mythology and legends. Look at how much of the American Revolution and Civil War is already steeped in pious fairy tales, such as young Washington's cherry tree, Betsy Ross, Paul Revere, or that utterly fictional, feminist chick who supposedly rode horseback like Revere.

Personally, I believe that this fake stuff that people believe is one of two things: either there are kernels of truth and allegory to them, that they're masking a deeper truth that's too dangerous to discuss openly or brazenly reveal; or that they're utter distractions and designed to keep people busy and concerned about utterly irrelevant things. Panem et circenses.
> First it started as 9€ ticket for 3 months.

That was a different Ticket. A highly subsidized time-limited offer. It was never meant to be economical. The 49€ is the economical viable solution, after a long discussion, which still is subsidized. And the 59€ is just the rise to fine-tune the price to actual usage and inflation.

> Really sad, as it isn't affordable for poor people anymore.

Poor people, as also students, get a lower price. Usually around 19-29€. And many workers can get it through their company, or can get something back from taxes. The amount of people who are really paying the full price themselves is probably not that high.
That’s great. But your situation doesn’t scale to everyone’s and you’re still below replacement rate (slightly above 2).

The community is very good indeed. That was always where I ended up finding answers.

I don't know whether I have seen worse. I may have seen 'equally bad', however.

There's a good chance that I'm just not good at understanding that style of documentation. I feel there is a huge lack of examples. The examples given are very specific and they do this thing where, when showing two examples of the same functionality, they change all the variable names and data-structures, making it impossible to follow.

But that may just be me. Some people might find it useful to see the same example with different data-structures and variable names.
Without trying to ridicule you, asking “what social contract?” In this kind of discussion is like a first year university student asking “what’s a fraction?” in first year maths classes.

The Space Shuttle was not fully reusable as the biggest single part, the orange tank, was destroyed every time. But more importantly, the orbiter and boosters needed 2+ months of refurbishment/rebuilding after every flight.

One of the design goals of Starship is for the booster and ship to relaunch with zero refurbishment. To literally land over the launchpad, refuel, and go back to orbit within hours without people even approaching them. The heat shield is the biggest risk to that goal IMO, and we saw today that it definitely sustained serious damage despite improvements. But if they ever get there then per-launch costs will be a tiny fraction of the Shuttle with 6x the payload.
The worry is that by better funding educators we might have to make do with less administrators, which could leave students less administrated.

Ok, but you were spreading misinformation in the process.
It is true that trades work has picked up quite a bit. High school kids and their career counselors say the reasons are:

- Well-defined career path.

- High pay as you keep going ahead.

- Union pay and benefits. Incredible stability. Incredible healthcare.

- No outsourcing.

- Lots of paid leave. None of that unlimited PTO scam.

- Lot of camaraderie. None of the corporate nonsense where execs take it all at the expense of people.

- Opportunity to start your own business at a certain point.

- No large student loan to get started.

While not all kids articulate all these points well, but they can tell how their seniors in college are grinding too much for little return - while trades people are working hard, taking vacations, raising families - and buying homes.

The average tradesperson in a HCOL is a millionaire by age 40 simply because they could buy a house earlier in their lives. And they are able to start families and live a very stable life. Kids are picking up on this.

They used a concave disk-like speaker to produce sound. This solid shape makes the sound waves kind of spin around themselves like a tornado or one of those bubble rings you see people blow underwater [1] instead of a normal pressure wave that goes in all directions.

The tornado sound wave can only move forward and once it hits something is dissipated and doesn't reflect the sound.

You can write OOP-style in C, FP-style in C/C++/Java or even PHP. Sure.

Writing pure FP code (pushing all the side effects to the "edges of the program" in C is possible! But it's going to take a lot of discipline from the programmers: there is no safety-net and lots of dreadful boilerplate.
