2022-10-06: How to configure neovim to properly format python code?. Simpler solution is to add this mapping to your after/ftplugin/python.vim: nmap <buffer> g= :!black --quiet %<cr>:redraw!<cr>:!isort -q %<cr>:redraw!<cr>. Not sure if we really need two redraw, but it works quite well. This could be put in an autocommand if we want to format on save, say. #vim

If you just want the executive summary, here it is: these are definitely interesting algorithms from an arithmetic complexity theory standpoint – especially for the case of 4×4 matrices over finite fields, where (to the best of my knowledge) Strassen’s algorithm from 1969 was still the reigning champion. These algorithms are also practically relevant, meaning that not only do they have better asymptotic lower bounds than Strassen’s algorithm, they are still algorithms you might actually use in practice, unlike essentially everything else that has been written on the topic in the last 50 years: these algorithms are correct, and will in principle win over Strassen’s algorithm with large enough matrices, but that cut-off is well beyond the sizes that anyone is actually doing computations with. — On AlphaTensor’s new matrix multiplication algorithms

Instagram users can only write plaintext without any formatting and it even doesn’t look nice onthe phone and you have to insert an image even in case you only want to post a message and youknow what? Nobody cares. I can only talk about russian speaking segment of the platform but theamount of activity there is just crazy. People not only share cat photos there, but also buy andsell stuff, write analytical articles, do workshops and trainings without any problem. The factthat sometimes they have to literally edit the photo and put a text overlay on top of it (and itoften looks like some of the worst myspace examples) doesn’t bother anyone. And all thecommunication is solved with a restricted instagram account or a closed whatsapp group. — From the basics to complexity and back

The academic prestige of Latin and Greek underwent a steady, centuries long decline. Where do C and assembly fit on this map? We certainly aren’t in a Medieval University, where these topics were mandatory, but neither are we in a post-modern sociology class, where the classics are not only dead, but whose distant memory haunts our conscience. — Learn enough C to survive

2022-10-18: TIL about FiraGO. Togther with Fira Math, it makes for a perfect combination of fonts for handouts and slides. Now, it’s a matter of adding the following declaration in my $\LaTeX$ preamble:

\documentclass[presentation,9pt]{beamer}
\usepackage{fontspec}
\defaultfontfeatures{Mapping=tex-text,Scale=MatchLowercase}
\setmainfont[Numbers={Tabular}]{Fira Sans}
\setsansfont{Fira Sans Condensed}

Despite the fact that I spend hundreds of dollars a year and hours of work to host my own email server, Google has about half of my personal email! Last year, Google delivered 57% of the emails in my inbox that I replied to.

I’m definitely not in favor of fossilizing Unix, but there’s a difference between avoiding fossilization and the kind of minimal, mathematical purity that we see GNU Grep trying to impose here. Unix has long since passed the point where it had that sort of minimalism in the standard commands. Modern Unix has all sorts of duplications and flourishes that aren’t strictly necessary, and for good reasons. One of them is that it’s nicer for the actual people using Unix. — We are stuck with egrep and fgrep (unless you like beating people)

I think it all stems from Apple’s desire to simplify things for themselves, architecture-wise — Apple Silicon is quite innovative in bringing the advantages of iOS devices to Macs (performance + power efficiency). The terrible decision, in my view, has been to also want to bring the iOS look and feel to the Mac. It was unnecessary, it has broken so many tried-and-true Mac interface guidelines, and it has delivered a massive blow to the whole operating system’s identity. Just to make the Mac what, more fashionable? — My next Mac might be the last

That’s right: what’s good for the lurkers is also good for everybody else. Just like all the great practices that enable remote work also made things better for anybody working in an office (if you remember what that was like and can believe that so many people just put up with that for so long), so does favoring transparency and following up on questions in the open improve all your team dynamics. — Learning By Lurking
