| Almost Secure

Right before the holiday season, LastPass published an update on their breach. As people have speculated, this timing was likely not coincidental but rather intentional to keep the news coverage low. Security professionals weren’t amused, this holiday season became a very busy time for them. LastPass likely could have prevented this if they were more concerned about keeping their users secure than about saving their face.

Their statement is also full of omissions, half-truths and outright lies. As I know that not everyone can see through all of it, I thought that I would pick out a bunch of sentences from this statement and give some context that LastPass didn’t want to mention.

Sierpiński Triangle Interpreted as Musical Notes - YouTube

The Sierpiński triangle (sometimes spelled Sierpinski), also called the Sierpiński gasket or Sierpiński sieve, is a fractal attractive fixed set with the overall shape of an equilateral triangle, subdivided recursively into smaller equilateral triangles. Originally constructed as a curve, this is one of the basic examples of self-similar sets—that is, it is a mathematically generated pattern that is reproducible at any magnification or reduction. It is named after the Polish mathematician Wacław Sierpiński, but appeared as a decorative pattern many centuries before the work of Sierpiński.

“Balkan Cosmology” by Bruce Sterling (2022)

“It feels good to run a bar when the people really need one,” Dad confided to Nikola, “but here at my ‘Stairway-of-Calvary,’ it seems that every night finishes sad.”

“Pop, they’re already sad people. They were sad before they got in here.”

At Berkeley Law, a Debate Over Zionism, Free Speech and Campus Ideals

Other legal experts noted that the controversy showed just how mangled the understanding of the First Amendment had become, even at a place like Berkeley, the epicenter of the 1960s free-speech movement. The debate, they said, should focus on whether these bans align with the academic ideal of open, intellectual debate. Even if student groups can prohibit speakers, should they? And should such bans be codified — formally adopted with a bylaw?

“There’s a real confusion about freedom of speech as a cultural value and freedom of speech as a legal concept,” said Will Creeley, the legal director of Foundation for Individual Rights and Expression, a free-speech advocacy group.

Leyrer's Favourite Things 2022

It’s probably too late to get some of this stuff for your loved one (which is usually the reason for these „favourite things” lists) but none the less, let me with you a few things I acquired and used or that sparked joy for me in the past year.

All links are evil Amazon affiliate links. Feel free to just copy and paste the names, titles, … and shop somewhere else :)

Top of my list is definitely Open Circuits: The Inner Beauty of Electronic Components, by Windell Oskay and Eric Schlaepfer. Such a wonderful, wonderful book that really sparks joy every time I open it.

Indispensable since I learned about them at Haxogreen are these little Baseus 65 W USB Chargers. Either as a wall wart with 2x USB-C and 1x USB-A ports or with a 1,5m cable to the block and with 2x USB-C and 2x USB-A ports.

I am so happy with my Plantronics Blackwire 5210 cabled headset (mono version), that I ordered a pair for a colleague who still shouted into the built-in mic of his laptop. I did it for our customers and colleagues ;)

Although the cool YouTube „kids” are currently all switching to the DJI Mic Wireless Microphone System, I am still very happy with the Rode Wireless GO II, especially when combined with the RØDE Lavalier GO Professional Lavalier Lapel Microphone. These act as additional microphones when connected to a computer and the receiver also acts as an additional recorder. With this setup I never lost an audio recording. And they sound awesome.

My favourite „business related” book this year was Kill It with Fire: Manage Aging Computer Systems (and Future Proof Modern Ones), by Marianne Bellotti, which I can not recommend to everyone working in IT strongly enough.

And of course my favourite „regular” book of 2022 was Amongst Our Weapons, by Ben Aaronovitch , the 9th installment in his „Rivers of London” series, which I love.

Last, but not least, I ordered it like two years ago, but it was finally delivered in 2022, the Ultimate Hacking Keyboard (UHK 60 v2). I took me a while to get used to, but now I am very happy with this „funky” keyboard from Hungary.

yt-dlp > youtube-dl

Ich bin ja schon ein alternder Gen-X Nerd und bekomme daher ja nicht mehr so mit, was diese jungen Menschen in diesem Internet da so machen. Daher hat es auch bei mir ein wenig gedauert, bis ich mitbekommen habe, dass das wunderbare youtube-dl (YouTube Download, siehe u.a. „Download-Tool: Musikindustrie verklagt Host-Provider von Youtube-DL”) nicht mehr wirklich weiterentwickelt wird (letzte Version v2021.12.17).

Dafür gibt es yt-dlp einen Nachfolger/Fork (also eigentlich Fork einen Forks), der aktiv weiterentwickelt wird und ganz viele spannende neue Features (u.a. das Entfernen von Sponsorenabschnitten in YT Videos) bietet.

52 things I learned in 2022

Musicians make life hard for programmers. There are nine different bands called Emperor, one band called Eximperituserqethhzebibšiptugakkathšulweliarzaxułum, and a side project called ⣎⡇ꉺლ༽இ•̛)ྀ◞ ༎ຶ ༽ৣৢ؞ৢ؞ؖ ꉺლ.

Using ellipsis in writing signifes the writer is Gen-X or Boomer and can read as confusing, passive-aggressive or even weirdly flirtatious to digital natives.

In 1739, there were three times more coffee shops per person in London than there are today.

YouTuber Mr Beast employs a team of six people to make thumbnails for his videos. Thumbnails are planned before the video is shot.

Mandelmap poster

Bill Tavis’s beautifully-drawn "map" of the Mandelbrot Set [via Kottke] looks like a chart from the age of sail.

The Superheterodyne Radio: No really, that’s its name

A crystal set is very different from an FM stereo, and that’s different still from a communications receiver. We’d say there are several common architectures for receivers and one of the most common is the superheterodyne.
But what does that mean exactly? [Technology Connection] has a casual explanation video that discusses how a superhet works and why it is important.

Mastodon on your own domain without hosting a server

In other words, if you want to be discovered on Mastodon using your own domain, you can do so by copying the contents of https://<your mastodon server>/.well-known/webfinger?resource=acct:<your account>@<your mastodon server> to https://<your domain>/.well-known/webfinger.

One caveat: this approach works much like a catch-all e-mail address. will match, unless you add a bit more scripting to only show a result for resources you want to be discoverable.

Edit: Seems there is a GitHub issue which requests custom domains as well.
Edit (15 Nov 2022): Folks have been using the approach of serving up webfinger on a different domain through proxy setups, e.g. using CloudFlare.

Moravec's Paradox

it is comparatively easy to make computers exhibit adult level performance on intelligence tests or playing checkers, and difficult or impossible to give them the skills of a one-year-old when it comes to perception and mobility

Hans Peter Moravec (born November 30, 1948, Kautzen, Austria) is an adjunct faculty member at the Robotics Institute of Carnegie Mellon University. He is known for his work on robotics, artificial intelligence, and writings on the impact of technology. Moravec also is a futurist with many of his publications and predictions focusing on transhumanism.
