@lyse@lyse.isobeef.org These tables get shuffled around every time your OS switches to another process. It’s crazy that so much is going on behind the scenes.

@lyse@lyse.isobeef.org I was surprised by that as well. 😅 I thought these were features that you can use, but no, you must do all this.

By the way, I now fixed the issue that I mentioned at the end and it works on the netbook now. 🥳

In-reply-to » @movq wow! what is assembler?

@movq@www.uninformativ.de @kiwu@twtxt.net it just so happens to be a happy coincidence that I’m extending mu’s capabilities to now include a native toolchain-free compiler (doesn’t rely on any external gcc/clang or linkers, etc) that lowers the mu source code into an intermediate representation / IR (what @movq@www.uninformativ.de refers to as “thick layers of abstractions”…) and finally to SSA + ARM64 + Mach-O encoder to produce native binary executables (at least for me on my Mac, Linux may some later?) 🤣

In-reply-to » @movq wow! what is assembler?

@kiwu@twtxt.net Assembly is usually the most low-level programming language that you can get. Typical programming languages like Python or Go are a thick layer of abstraction over what the CPU actually does, but with Assembler you get to see it all and you get full control. (With lots of caveats and footnotes. 😅)

I’m interested in the boot process, i.e. what exactly happens when you turn on your computer. In that area, using Assembler is a must, because you really need that fine-grained control here.

In-reply-to » H… Ho… How have I not heard about vim-tagbar before? 😳

@lyse@lyse.isobeef.org Yeah, well, given that I didn’t need this for such a long time, it’s probably not an essential tool. 😅

I’ve often wanted to have an outline of text documents, though, and tagbar/ctags can do that as well:

https://movq.de/v/abc58e6d66/tagbar-latex.png

This isn’t as powerful as the “Navigator” tool in StarOffice/LibreOffice (which can be used to rearrange the document), but still pretty useful:

I like this. You get performance that’s more or less in the ballpark of C, but without the footguns.

Got a nice conspiracy theory for you:

https://mastodon.social/@mcc/115670290552252848

Actually wait I just thought about this and realized that the precise timing of the ACTUAL GitHub seed bank, by which I mean the Arctic Code Vault, on 2020-02-02, makes it more or less a perfect snapshot of pre-Copilot GitHub. Also precisely timed before we all got brain damage from COVID. This is the only remaining archive of source code by people with a fully working sense of smell

(Bonus points because the Arctic World Archive is located in Svaldbard and that’s the name of the AI in Stacey Kade’s “Cold Eternity”.)

@shinyoukai@neko.laidback.moe it was a mess, we are better without it. Until a new mobile client comes (not holding my breath), Yarn is very usable on the mobile, just using the browser.
