Their money is moving, because old people—at a higher rate than young people—become dead people, whose former money is then controlled by someone else, often younger.
It seems that the one-size-fits-all tool is a tough row to hoe.

Part of the reason that LaTeX works at all is that it targets, as you note, (essentially) .pdf.

Trying to pack so much precision into a web/os tool and make it performant, would seem beyond the reach of a real-world business case, as far as I can tell.

At this point, I would reach out to my boss and ask "Do I book it at twice the budget?". If my boss says yes, the company covers it. If my boss says no, then I don't go. It's as simple as that.

What's heavy about any of that? I don't know what Tomcat is, but Docker is just a means of installing and running software in a VM(if host isn't Linux), Java is a perfectly fine language and runtime, and Postgres is a powerful and widely-used database. Any other self-hosted web app would require at least a language runtime and a database.
Looks like a misunderstanding.

If you are following djb's researches, you'll know he doesn't have an agenda of attacking open-source cryptographic implementations as "problematic". Instead, his actual personal agenda is: most, if not all cryptographic implementations does not work correctly, and lots of work is needed to fix that. It's also obvious if you read beyond the first few pages of the slideshow.

So yes, he does work correctly.
Virtually everyone at school used Overleaf. Impressive bit of kit, particularly since the version 2 update. I was fond of how v1 kept everything in a git repo though.

Small correction, it's not a monthly amount but rather the statement amount of last month plus this month's spending, so I'd reduce that number by roughly 25%. I don't argue with your other points.
The problem with domain specific tools for project management is that everyone has slightly different goal, priorities and requirements. So you end up with a mess of a tool that barely works (Jira) or one that's missing necessary features. Then someone decides they could do it faster and better in Excel.

Google is maybe the only other company with the capability to collect the data necessary to solve self-driving. But they don't own the car production, they need to partner, and hence are at the whims of traditional automakers' margins and product designs.

Tesla is collecting sensor data from their entire fleet, probably mapped to when the user needs to override autopilot. A really elegant source of training data when you think about it.

> It is remarkable how often zealots are eager to sacrifice the lives and well-being of others to achieve their 'liberty'.

I also find it remarkable how often people are willing to sacrifice any amount of liberty in the name of preserving life.

Would you be willing to accept a police state where AI-controlled body cameras are required to be worn by all people at all times? That would certainly deter a lot of crime. Of course it's an obviously ridiculous extreme, but it serves to illustrate that you don't really believe that in a tradeoff between liberty and safety, we should always decide in favor of safety. All we're arguing about is where to draw the line.

> Untraceable communication is a tremendous force multiplier for crime, terrorism, and foreign political de-stabilization operations.

And it is only very recently that our government was even capable of beginning to block it. Untraceable communication has been the norm for all of human history. We survived. You act like law enforcement is powerless without it, but of course that's not the case.

> That you want to increase the effectiveness of those things is very scary.

That you insist on reducing me to a caricature in order to demonize me is very childish.
Here an interesting attempt to apply LaTeX to a javascript package called MathML with which I'm unfamiliar.

https://www.maths.nottingham.ac.uk/plp/pmadw/lm.html

There is some exploration at the site itself that is worth looking through if anyone plans to attempt LaTeX markdown being interpreted-and-served.

The Unix Philosophy in me thinks "use lynx. oh and forget https, use gopher to serve. when you hit a .tex switch to a program that's supposed to do that" etc etc etc but I definitely think the entirety of the internetworkings - i.e. not-exclusive-to-hackers - would benefit from *TeX markdown being as common as HTML (perhaps not AS common, but more common than currently).

Have you looked at Scribble? It's very programmable, and evaluated similarly to TeX or LaTeX, but in a more powerful and straightforward language (Racket).

It's used by academics to write conference papers, it's used for most of the Racket books for both Web and camera-ready typesetting for print, and I've even used it for embedded API docs.

https://docs.racket-lang.org/scribble/

(That manual itself was written in Scribble.)

(I'm actually thinking of moving from Scribble to Markdown for embedded API docs, as part of an open source ecosystem goal, to make docs for reusable modules more lightweight to add, but it's hard to give up some things about Scribble. For example, for one module, I needed substantial documentation about each opcode, and wanted it to be formatted similarly to an API function, but with different meta properties, and some tricky formatting. Scribble let me make a simple semantic form for that, separate from formatting, like LaTeX would.)
The more I see comments like this, the more convinced I am that there is some sort of conspiracy to restrain and otherwise beat into submission users by forcing them to use hideously overcomplex software that can execute arbitrary code, and which is controlled by effectively two large organisations (one of which already has immense power over the Internet), just to view a website that is nothing more than a static document.

Nothing on that site needs JS. Nothing on that site should need any more than a browser that can display text and images. This isn't a fancy "web application" or other JS-based thing.

You should be more skeptical. A LOT more.

Take a look at this article, which is a brief summary [1]. Among other things is this paragraph:

“A spokeswoman for the Beer Industry told Bloomberg that though the tariffs are not “100 percent” to blame for the industry’s losses, there is reason to believe that “brewers are making fewer investments because of the added cost of aluminum.” In the year before the tariffs were put in place, beer jobs had grown by 27 percent.”

Read that again - a whopping 27% increase in jobs in ONE YEAR!!!

Also in the article...

ALL alcohol sales declined in the following year. And beer jobs are UP 8%. And aluminum costs “doubled” despite a very modest 10% tariff.

I could go on, but my god, this report is 100% full of shit. And I’m being kind. Seriously. And I don’t care if they hate trump (or any other president). They should be called out for such BS. But because Bloomberg hates Trump, they won’t do it, which is dumb. Either call someone out when they are full of BS (regardless of political persuasion), or get out of the business.

Nearly every post so far is rah-rah pep, and while I agree with most of the sentiment I’m going to offer some different advice.

Before 30 I hustled a lot to make enough to have roomates and live a fairly frugal life. I had family obligations that kept me from some personal goals. But largely I was saving money and even though I worked 2 jobs I enjoyed life.

30 was when I started working as a dev, making substantially more money. And while I was hoping to sock away 50% of my gross income for a couple years, so I could pursue some entrepreneurial ideas, it logistically got harder at 30.

Friends were starting to have kids or just move in with their significant others. Just finding a cheap room with people I wanted to live with got significantly harder. At the same time it was harder to be that guy socially who would show up to a potluck without a significant contribution and have a real reputation for being a mooch from people who know your earning potential based on general skill sets.

On top of that life happened. I moved in with my girlfriend. I had got married. I got a herniated disk. I had a kid. I bought a house. I had another kid (surprise! twins!). And now, at 41, I can almost breath again. I am very grateful for having stable income during the rollercoaster that was my 30s, I’m not sure how I would have survived. I certainly didn’t have the energy or time to focus on building much of anything during that time (though I did try some projects, one of which might be worth something if I hadn’t burned out on it).

So I will tell you this. You can put off certain things until early 30s. But if you think you want kids, or even just a good relationship with someone else, 30 is starting to be a time to think about earning solid money instead of trying to build something that will still consume your attention after 5pm. The pick up the torch again in your 40s or even 50s if you want to build something. With any luck you’ll have more capital to work with which will make things easier.

Keep in mind, I’m not telling you to give up. Or that you need to catch up with anyone. Only that there is no shame in putting off some things, to build some reserves and focus on other things that can’t wait.

And if you have no desire for kids (and kids are a pain in the ass, and I’m not sure when they’re finally worth it), then really there’s really no reason to stop trying until other obligations (say a girl/boyfriend) force you to.

edit: I didn’t mean to imply significant others would ever force you to stop (ones who did would probably not be healthy to stay in a relationship with). Only that some obligations are worth putting some things on hold for a year, or a decade...
Yeah, everyone should be forced to run arbitrary code on their computers, you tell'em.
40,000 in the INDUSTRY.

An industry of 2,190,000 people.

That’s less than 2% over three years (including 2016, 2017, and 2018 according to the article).
What think is it's the interaction between coherence and the number of people you have working towards a goal. The thing is the multiplier effect of more people isn't linear. But crucially depends on the amount of coherence management can impose on it's work force. It turns out the multiplier effect is strong even when the coherence is low. Which is good because it's hard to impose much coherence on large groups of people

How that looks depends a lot of where you sit. If you are on the inside you see the lack of coherence up close. On the outside you see the collective power of the organization. There is enough coherence that the multiplier effect is still very positive.
I did actually write a separate article on this exact subject, which I think is also pretty good.

Cool.

I've written my share of Forths, but none in Go. Lisp is definitely more involved, especially expanding macros and juggling environments.

So iOS does it one way, Android does it another, and your old DSLR still stores data in EXIF? Sounds like a great way to be locked into a certain vendor.
Looking at the 4d toys video, it occurs to me that we can't really see in 3d, we only see these 2d projections. But it's far more information rich than a slice, and we can mentally model 3d. Some of this is certainly an innate ability to model 3d, and familiarity with the component shapes. But it also comes from shading and other surface area effects.

Could 4d be projected onto 2d in this fashion? Not a slice, but more like a shadow with surface effects. Maybe with red/green/blue lights in different positions in 4d space?

At what point do you say: this child just isn't meant to be? Why would you subject someone to a life of annual spinal injections, and society to the huge financial cost?
I would wager that doesn't make up for how much slower the hardware is, though.

The 4MHz value is the clock speed, but all instructions take a multiple of 4 clock cycles to accomplish, so you often talk about it as a 1MHz "instruction cycle" machine.

The fastest memcpy implementation I've seen for it (not including in-hardware DMA features, which are only available for copying to OAM (sprite) RAM on the original gameboy) takes 4.5 cycles per byte (one 16-bit word every 9 cycles).

That means that if you were trying to update every pixel on the screen (which doesn't actually work - the GB's screen pixels aren't memory mapped directly but generally specified via a combination of up to 384 unique 8x8 tiles, which are then arranged on a 20x18 tile grid), which would be 160 * 144 * 2 bits/pixel = 5760 bytes, it would take 25920 instruction cycles ~= 24.72ms, which comes out to approx 40.45 FPS.

Of course, as I mentioned, the actual GB doesn't work like that, and has a Pixel Processing Unit that handles writing to screen every frame. While the PPU is writing to the screen, the CPU cannot access VRAM, which means that the CPU actually only gets what's called the v-blank period, which is only 1140 instruction cycles, which is only enough time to copy up to 254 bytes or so (I'm skipping over some detail here, like how you could squeeze a few extra bytes out by loading the first 4 or so bytes into registers before vblank begins, or how you can also (with very careful timing) write to VRAM during a ~60 cycle window on each line knowing as the h-blank and OAM search periods).

In practice, games work despite these limitations because they generally only have to modify a small amount of the screen in any one frame. Scrolling is implemented in hardware, and you can write new data off screen then scroll into it so you can take multiple frames to write it if needed.

This plus other tricks (for example, animating 50 copies of a common tile by editing the tile's pixel data, which affects every copy at once) let these games accomplish so much with so little.

It's impossible to compare to a modern sytsem with a polygon-based GPU, they're entirely different things.
I use Dynalist which is also similar to workflowy.
Sorry to cut you off if you were being sincere. I specifically pushed back on the being 10 thing from the other comment after it rubbed me the wrong way, and then you pursued basically the same line of questioning without acknowledging anything I wrote.

Random LaTeX question: Does anyone have any tips for writing LaTeX code to avoid typos or other mistakes? I.e., using the fact that LaTeX is a programming language and not just markup language to catch mistakes?

I started adding what basically are assertions to my TeX files. These have caught a fair number of errors. I also periodically run "static analysis" scripts to catch writing and coding errors but these tends to have many false positives in my experience. E.g., chktex and these: http://matt.might.net/articles/shell-scripts-for-passive-voi...

But I'm thinking there may be good coding styles or habits that could prevent errors too. Any ideas?
