I think this is important advice that needs to be repeated over and over and over again. The number of software developers who get caught up in the latest fashion choices, instead of carefully picking the right set of tools for the job, is

Mentioned, yes, but often not learned. In many situations the only thing that matters is the constant factor. If the number of data items is relatively small, the difference between N log N and and N squared may be completely dominated by t

Agreed. If it stored data on a different server (allowed via CORS) then there could be some additional security, since then as a long as the JavaScript isn't subverted on the same site, you're storing encrypted data on a differ

Almost certainly not. EARN IT doesn't technically forbid encryption, it just lets an unelected board decide the legal requirements for communication without being sued into oblivion. But the unelected board will be under the control of

Yes, because that next alternative could be a scam site. When people are desperate for information, they will get it wherever they could find it, even if it is garbage. It is much better to have the good sites stay up.

Actually, JavaScript often is not good for that either. Static sites compress really well, and static HTML typically renders orders of magnitude faster than running JavaScript to create commands to eventually do the same thing. In addition,

Thanks so much for the swift fix, apology, and the current work to try to find out what happened & prevent the recurrence of the mistake. Mistakes are inevitable, especially at scale. I think taking those steps, when the inevitable mist

An action that is an honest mistake isn't disgusting; it is simply a mistake. We all make mistakes. Anyone who makes no mistakes is not doing anything useful. What matters is doing the right thing after the mistake is discovered. I a

This looks like a terrible but honest mistake. The repo is already back, after something like an hour and a half. The . io website is not back yet, but I suspect that takes a moment to get back running.

POSIX does not specify the path of anything. It says that "sh" is a shell, but doesn't say that "/bin/sh" is that shell. See: https://pubs.opengroup.org/onlinepubs/9699919799/ I

Thanks for the link, I've started reading it. The complexity of defining and determining "actual causality" is a good justification for mathematicians' avoiding the whole thing and using material implication instead. As

I expect all Airlines to cancel many of their flights and have to temporarily lay off a lot of their people. It is unlikely a lot of people will be doing travel for mamy weeks, and I suspect the ramp back up to normal will be slow.

To me, this shows the huge risk of building on a language/platform that depends on a single company. This even happened earlier. Visual Basic .NET is grossly incompatible with Visual Basic 6, so much so that Visual Basic .NET is essent

Yes, the y2k crisis was real, or more accurately, would have been a serious crisis if people had not rushed and spent lots of money to deal with it ahead of time. In many systems it would have been no big deal if unfixed, but there were a h

It's a fun essay, but because of the way it's written, a reader could easily confuse "second order thinking" with "understand why a decision was made before planning on changing it." I think the author distin

This is HTML5; this doesn't have anything to do with GitHub or Markdown. Markdown passes through HTML (by default), and HTML5 includes "details". Almost all browsers support it, but IE (even IE 11) does not: https:/&#x2

If you're worried about malicious differences, "regular" PDFs are worse. As noted in the article, it is extremely difficult to figure out the original text given only a "normal" PDF, so you end up using a lot of heu

The best technique for having a PDF with extractable data is to include the data within the PDF itself. That is what LibreOffice can do, it can slip in the entire original document within a PDF. Since a compressed file is quite small, the r

Yes, 8088. Thanks for the fix. The 8088 was a 16-bit CPU with an 8-bit bus. The 8086 was a 16-bit CPU with an actual 16-bit bus.
