That's very interesting and explains a number of things. 4MB writes seems pretty high though as a minimum write block size, I've googled but can't find details among the sea of pages trying to sell me SD cards, won't you

Using Ctrl-[ is perfectly fine if that's convenient to you. Some people doe "inoremap jj <esc>" and double tap j to exit insert mode. If it's faster for you than pressing regular escape, it's an improvement, a

Here's my best take at this so far, I wrote it in 2007: Why, oh WHY, do those #?@! nutheads use vi? http://www.viemu.com/a-why-vi-vim.html

No, you didn't miss anything. As you probably expected, it's just my deductions from context. I may be completely wrong. I still do believe in them, but obviously no one else needs to.

If so, it would be in the unusual shape that it is a top-dollar one rather than cover-the-failure-with-a-pretty-ending one. But in this case, Zoom is probably actually interested in the security tech that Keybase has apart from the talent,

TSMC is reportedly investing $20bln in the plant for the next node (more advanced, smaller, faster, less-power-hungry technology). Few companies can invest that kind of many. And for the ones that could, it's often better to invest it

SD cards as present on Raspberry Pi, even the Pi 4, don't go beyond ~60MB/s. Older Pis get around ~20MB/s. It's the worst bottleneck of the system. Where do you get that 1 GB/s figure from?

Indeed, thanks for the correction.

Is there even a doubt? Windows has a chance at supporting the open, documented interfaces of Linux. Linux has no chance at supported the closed, undocumented interfaces of Linux.

Bravo Finland. I remember attending Assembly'94 in Helsinki. So many good things came from the demoscene, including Tran's PMODE...

Isn't this paper more about simulation techniques than about reality itself? It looks like time reversibiliy (sub-planck length or otherwise) should be studied in closed form or at least in non-lossy mathematical ways, not simulated wi

Beautiful, beautiful project. Containing the deepest twists of computation in a single file, and not a single #include. I only missed it including a text editor. Love it!

If you basically don't know how to code in assembly, learn 16-bit x86 with whichever method you find, it won't be wasted. You can extend most of the knowledge from 16 to 32 bit substituting register names ax,bx,cx,dx,si,di,bp,sp y

I used a single log.txt file between 2005 Nov 4 and 2014 2014 Aug 11. This was instrumental in my professional life between those dates. Business ideas, call stacks of ViEmu bugs that I worked on, passwords, financial forecasts, bug and fea

Maybe emily-c knows the details. If the processor starts in real 16-bit mode these days like it used to do in the past (8086-compatible instruction decoding, flat mapping form virtual to physical memory, protected mode features mostly disab

Thanks for the very complete explanation. It makes sense that this would work this way.

That doesn't depend on BIOS, it depends on the standard "frame buffer" address for CGA/EGA/VGA graphics cards (I'm not 100% sure they all use the same address, those three and Hercules were the standard back in

Oh, my bad, I misread the datasheet, read "A9" where it says "ARM9". Thanks for the correction.

It’s an A9, same as on Xilinx Zynq 7000 series, 32-bit ARM core with full MMU.

Because the original was actually Acorn RISC Machines. They might have as well gone on to become "Acorn", well in line with Apple, which they power nowadays to a large degree, and which they might power to a much larger degree in

That's brilliant! I could recognize Abu Simbel Profanation, and maybe Elite? My first steps learning programming were Basic and then Z80 assembly language on a ZX Spectrum...

The developer in question has probably lived some pretty bad 40 years with nightmares about the issue. They might be 60 now, or 80, or already passed away. Only bright spot was probably the fact that they were not known and thus it didn’t h

Rename is the most atomic you can get on Unix. Original article talks about partial file updates. New SQLITE file + rename should be as failproof as possible. And I’m any case nothing is 100% safe, so redundancy is a hard requirement for r

Most (if not all) Linux distros come with a “vi” (mandated by Posix) which is a plain, basic, feature-starved build of vim. I believe Posix having included vi as a requirement contributed to the status of vi as the omnipresent text editor.
