Something similar for Emacs, inspired by this Vim method: https://karthinks.com/software/latex-input-for-impatient-sch... Not my field, but I find it interesting to see how it is possible to optimize one environment fo

Such renaming is part of the LSP protocol, so any LSP supporting editor (Emacs, nvim, etc.) will support this as long as the used language server does. I can do this with clangd and Emacs, but it's not Emacs specific anymore. There may

Which indicates it's opt-in so off by default. Also there's a pretty clear (IMHO) configuration in the settings that states what is send based on the level you select. So what's the problem? It's only a way to contribute

> That way lies madness That way lies Emacs ;) That's the key difference between Emacs and most other editors: there's no limited API for extensions. There's a base C runtime, and all the lisp code on top is at the same le

I immediately liked "git the architecture", but stayed away from it a long time because of what I though a poor user experience. I attributed this to the clunky CLI, but you're right that the richer state was also part of the

I'd recommend just installing the "tlp" package, it includes most of what PowerTOP does and is "install and forget". Just an anecdote: I'm using Linux on a professional laptop, the same most of my colleagues us

GEA1 has never been in 4G nor 5G. Both support the same suites: AES-CTR, SNOW 3G (introduced with 3G) or ZUC (Chinese) with 128 bits keys and Western operators use AES.

It's a valid concern, but it's a contractual problem more than a technology one. Companies doing smart meters are not taking the basic subscriptions made for the public. They have dedicated contracts with their telcos, with commit

The pair in lockstep is "close", in that it only includes the core and deterministic private resources like core private caches. Shared resources like a L3 cache are outside of the whole pair, and can be seen as accessed by the pa

You can run zoom, and skype for that matter, using firejail [1]. There can be glitches now and then, in my cases only with skype IIRC, but it's rare and usually quickly fixed (just update your local configuration from upstream). [1] h

Partially. There are local (L2) and fast re-transmit with ARQ [1] and HARQ [2] (at least in cellular, which I know, but I guess Wifi likely has both too), and it can help hide some packet loss to the upper layers. But this still creates add

Yes. The same apply to a lot of embedded systems. When you can't stop the system you better learn how to debug from logs. And put the right logging support in place ahead of time: it may be impossible to replace the software in place b

It's very good move. First, it's for embedded: if you're not designing system on chip it won't matter to you. But for those who design SoC, and who needed embedded CPU of intermediate power, it's very good news. ARM

No, the parent is right. Moore's law is about the transistor density of the least cost process. This is a quote from Moore's paper [1]: "The complexity for minimum component costs has increased at a rate of roughly a factor o

No, it's not the GPU ISA. Complex chips tend to embed management cores, for example to handle power management or various configuration operations across the chip. NVidia used a proprietary ISA (Falcon) for such cores, and moved to RIS

mmap is not only to map a file content into a process address space, it can also be used to request memory from the OS using the MAP_ANONYMOUS flag. Early on a malloc-like allocator would use brk/sbrk to get a chunk of "raw"

There is no need for advanced nodes for micro-controllers. Typically even advanced µC use 40nm, planar, where the TSMC leading node is 5nm FinFET. ST also does FD-SOI 22nm if I remember well, but that's the densest node they have and n
