There's a misunderstanding here: I'm not saying "don't complain". Complaining in itself is fine, and others are complaining on this topic in a way that looks OK to me (and will probably be more efficient too). It&#x

The article is just his author view. Please read the emacs mailing list threads to get the full picture. GP is correct, and this is quite normal: some people using Emacs master will not follow all the mailing list discussions and commits. S

Thank you @tarsius! Couldn't have said it better. To add, I have issues with the attitude shown by the blog author. If you use the development branch, you can't raise hell when there's a breaking change: it's to be expec

Read the mailing list thread: the patch did much more than making the change optional, it did revert other related changes. That's why it was rejected. Other discussed changes were taken in, and it's not settled yet it seems: the

Not really, GP was talking specifically (and exclusively) about the ease of decoding the native ISA. Yes, modern x86 are wide from the uop cache, but this cache is made of simple, easy to process uop and not native instructions. The nativ

Maybe it's more than you want, but "Computer Architecture - A Quantitative Approach" from Hennessy and Patterson is a very good reference. If your main interest is CPU cores even a relatively old version will be enough. From

Same here ;) But now there's "8 GB and constantly swapping": Eclipse! I logged once on a dev server to test something, it was slow and I checked what was going on. On this 64 GB machine, 8 Eclipse users, each Eclipse usin

Ok, I should have said relatively, or even better "subjectively", small C source base. The C base supports many platforms and variants, so only a part of it is used in a running Emacs instance. And to the 1+M lines of elisp one ty

Literally changing the editor code, to do whatever you want. Emacs is a lisp (elisp) environment mostly with a small C based core for performance sensitive primitives. But the user code is at the same "level" as the Emacs core cod

For static analysis I use CodeChecker, it's a wrapper on top of the Clang static analyzer and Clang tidy (linter). Now also supports cppcheck, but I disabled it (too many false alarms). It's free and open source, and I find it use

Often much less in practice: 2G transmission was up to 2W, but 2G has been phased out in many countries. 3G I'm not very knowledgeable but IIRC was up to 800 mW (common case). LTE/4G is 200 mW maximum for sure. 5G is the same exce

This is what Org mode does. It's still very tied to Emacs, but there's an effort to standardize the Org format. Hopefully this will help its adoption outside of Emacs, it's a nice markup (and a lot more).

By using several small chips instead of a big monolithic one, it's possible to reduce costs in 2 ways: 1) the yield is better for a small die. For a given density of defect, a big chip will have a higher probability to have a defect th

As I understand it the Clang static analyzer is not intended to be used directly. It's best to use it through CodeChecker, which provide high level commands and do the low level calls to the Clang SA (and also Clang tidy). In particula
