Just to clarify, I think a lot of the Tek terminals that could generate graphics also lacked CPUs.

I don't know if anyone has dumped the Tek font ROMs, but the IMLAC Scroll Saver tty emulator has been preserved, and I converted its typewriter font to Hershey font format. Scroll Saver disassembly: https://github.com/P

Try out plotutils and Gnuplot. Not sure what the options for SVG conversion and the CSS box model are...

The ADM3A was slightly more than a dumb TTY; it supported direct cursor addressing despite being made of SSI TTL chips. It was the main platform for vi. I bought a used one at a government surplus auction and, many years later, wrote an e

I think the Gnuplot license is uncontroversially a GPL-incompatible free software license? https://www.gnu.org/licenses/license-list.en.html#gnuplot

The instruction sets were a lot simpler at the time. The 8080 instruction set listing is only a few pages, and some of that is instructions you rarely use like RRC and DAA. The operand fields are always in the same place. My own summary

Mechanical applications at that scale are not well developed, but that doesn't mean their potential is small. Member sizes below the critical diameter for flaw-sensitivity are crucial to the hardness and durability of, for example, hum

Aha, thanks! That makes a lot of sense.

What hourly wage are you imputing to your cooking to get US$10 for a meal of asparagus, chicken, and rice? My estimate for the materials would be: - 250g raw chicken wings: $375 ≈ 30¢ (I bought these on Saturday, so this is the current pri

They say the mosquito proboscis has a 20 μm inner diameter, "100% finer" than commercial alternatives (presumably meaning half the diameter). Not having read the paper, I'm guessing it can't handle 210° molten PLA.

No, guaranteeing that a solution to a general computational puzzle found in a finite amount of time is within some percentage of optimality is impossible. You must be talking about a restricted class of problems that enjoy some kind of tra

You ask, "Where do you eat when you downgrade from McDonalds..Wendy’s? It’s a sad state of affairs." On the off chance that this isn't a joke, you need to know that eating out is very expensive in the US, even at McDonald&#x

CI runners would be the main advantage of GitLab over bare Git, I think. Also if you want to show other people your personal project at some point, it may be nice to be able to link to a diff or a historical version of a file that they can

I was thinking because of Gödel's incompleteness theorem, but maybe there are multiple kinds of full generality. Wolpert and Macready seem to have been thinking about problems that are too open-ended to even be able to write a program

This is a 521-page CC-licensed book on optimization which looks absolutely fantastic. It starts out with modern gradient-based algorithms rooted in automatic differentiation, including recent things like Adam, rather than the historically

Yeah, I think that's the right answer. Dissolve it in water and run it through a smallish filter. Other impurities in the salt can clog the filter sometimes.

I don't care about the objective parts; the chemical and mechanical processes would have been exactly the same if it had been Lisa's lip that was bruised and bleeding instead of my own, or the lip of another boy halfway around the

Biology can use discrete methods; we have discrete neurons (and other cells), discrete chemical species like ATP, discrete amino acids, discrete genes made of discrete nucleotides, etc.

Wordpress is kind of a pig, yeah. But unless you're running WebSocket or server-sent events or some other Comet thing from Wordpress, you can solve the concurrent-connections problem just by limiting the number of concurrent PHP proce

by kragen 11mo ago
"Concurrent connections" and "connections per second" are two different measures which you are confusing. The second one is basically the same thing as "hits per day", and the first one isn't relevant.

Hmm, I guess you're right. Also EBCDIC does have ^ apparently, though not ↑: https://en.wikipedia.org/wiki/EBCDIC#Code_page_layout But IBM's BCD character sets, including the 48-character ones you allude t

Oh, I was using a shell script spawned from inetd as the lowest-tech, most primitive, worst-performance simple way of running a web server. A random PHP-running blog will easily handle tens of millions of hits a day unless you way overcomp

Oh, well, writing your own dynamic DNS system is certainly a great learning project.

I remember one time at summer camp in the teen dorm I claimed that pain was an illusion, because it was subjective. A girl named Lisa picked up a wooden block and threw it at me. It hit my lip, which started bleeding, and she was immediat

Computers are fast now. You can serve five million hits a day with a webserver that's a shell script running from inetd. You don't need Cloudflare unless you're getting DDoSed.
