> benefits of abstracting and separating node types from payloads If you mean being able to a generic `list<foo>` type (whether by C++ templates, macros, or good old void* casts), it's more than that. The benefit of non-intrus

I'm not american, and didn't follow that one deeply, but presumably that's not just "due to bad req. gathering", it's also due to the structure of gov procurement? E.g. it wasn't the pained users who appr

That's just one half of it: Intelligent defaults + configurability of what files/dirs to skip. That part has been iterated on in prior tools like `ack` and `ag` and `git grep` for like a decade, and ripgrep was informed by that t

This is a stunning achievement for many reasons! Having been born in USSR, a particular reason it moves me to tears how this vindicates Bulgakov's famous "manuscripts don't burn", which he presented as a plain metaphysic

I know how to use a slide rule, but only because my grandpa taught me. He was an electrical engineer with serious mastery of analogue circuits and relays, and a passion to explain; but he never really grasped what my father was doing as d

Aliexpress has a lot of cheap "smart gomoku board" now, they are cheap rgb-lighted membrane button grids O(13x13) with firmware playing games like Go, Reversi etc. ( https://he.aliexpress.com/item/1005010089221

Caveat to those considering buying PineBuds for "open source firmware": OOTB they come with fully working but proprietary firmware (part source-available SDK, part closed). The hardware is not 100% documented. There is open fi

That's not how I understood it. Full clones are big but simple — the server just sends all the packfiles. A first shallow clone needs some server work, but that's cachable, OK. But then on subsequent interactions between a git c

Computers are not a kitchen. They are clay, they are Lego, they are jungles of imagination. It's true that our current trajectory devolves their universality to a set of discrete isolated applications == multiplexing a set of applianc

I'm not sure of the timing (and whether you're sarcastic) but yeah, I found it funny compared to PARC showing Steve Jobs how the Smalltalk environment allowing modifying GUI behavior at run-time let them iterate quickly, sometimes

I disagree. Assuming it's their own device, set up automated backup, but let them trash the OS. PCs/laptops are (still) pretty much un-brickable at software level. If they do, re-installing & fishing around the backup will b

https://criu.org/ (Checkpoint/Restore In Userspace) is a long-running project (i remember the name over a decade ago) worth checking... Ooh, looks like they made progress in conveniently connecting it to containers.

Conversely, when you already collaborate with people in Dropbox, mainly via files, having real time co-editable docs under same folder with same sharing was nice, esp. for people who never remember where they put stuff :-) Integration was n

Radxa X4 board specifically has x86 N100, an M.2 slot (a short one) and GPIO (though you need to flash the on-board RP2040 to access them? haven't tried yet). I'm quite happy with it as a cheap desktop. Documentation is pretty

I upgraded my son from Scratch to Snap! ( https://snap.berkeley.edu/ ). Snap has a much higher ceiling, including collections, first-class code pieces, higher-order functions etc. It pretty openly describes itself as a &quo

You could add "without using multiplication or division" as a less arbitrary constraint. Early microprocessors (and some really cheap microcontrollers still) didn't have the circuitry. That said a fixed-factor mutiplication

Ctrl+T does transpose-characters (and Alt+T transpose-words) in Emacs. I assume it's not a coincidencce, I see tcsh has `bindkey -e` / `-v` for Emacs/VI bindings. Same keys work in bash too (and anything else that uses readli

I wish apps that open a document for editing would embed some kind of p2p "signalling" (webrtc or otherwise) in or near the file to bootstrap more real-time collaboration. That could be magic because it'd kick in IFF the file

What benefit would you get if tmux itself became a control mode client? You'd get pretty much same experience, with textual splits, modeful keyboard shortcuts to access scrollback & copy/paste etc. — which I'm not saying

It's curious how the original 1981 paper [1] on TECO Emacs, written before I was born, describes many qualities I recognize in the ELisp Emacs I grew up on. Emacs "happens" to be open source ;-), but the paper stresses how th

There is also Snap! ( https://snap.berkeley.edu/ ) which starts very much like Scratch but has higher ceiling. The deepest pedagogical benefit is you can easily build for him custom blocks — even custom control structures — t
