Over the holiday break I was looking at one of my old projects, µLinux. Turns out I did a fine job realy and have decided to revive the project 🥳 – Just getting the build/tests woring on my Mac Studio (Apple Silicon). Check it out! 👌 #µLinux

How do land that job with a Unicorn

First off, you’ll have to define what da fuq a “Unicorn” is! 🤣 My understanding a Unicorn is a mythical creature with a horn on its head and wings 🪽 🤦‍♂️

Poucos se lembrarão - e isto nunca figura na história contada sobre o #Aeroporto Humberto Delgado quando os agentes políticos ou a comunicação social falam do assunto - mas este Aeroporto era suposto ter sido encerrado o mais tardar em 2015, segundo um parecer de 2006 da Comissão de Avaliação #Ambiental do mesmo.

Nove anos depois, os custos acumulados relacionados com o ruído deste aeroporto na saúde dos cidadãos de Lisboa, Loures e Almada (incómodo, morbilidade) e em termos económicos (perda de produtividade, subvalorização do património imobiliário) desde 2015 calcula-se já superior a 10.000.000.000€.

Um novo estudo mostra que milhares de casos de #hipertensão, #diabetes e #demência na Europa podem estar ligados às pequenas partículas emitidas pelos aviões, e que foram encontradas no sangue, no cérebro e até na placenta. Estima-se que as partículas ultrafinas decorrentes da atividade do aeroporto de #Lisboa possam estar na origem de 15.473 casos de hipertensão, 18.615 casos de diabetes e 1.837 casos de demência entre a população da cidade e arredores, ou seja, no total cerca de 36 mil casos de doença; isto é, até 9% da população num raio de 5 km com doença atribuível ao aeroporto.

@bender@twtxt.net I reviewed my solution and it’s pretty much spot on! 🤣 the order of magnitude performance is anywhere between 1-10ms

This month’s reading prompt is #cozy and this #fridayreads I’ll fulfill it with the second of the “Lord Peter” crime fiction novels. Last #December I read the first and honestly it was a disappointment, both in terms os Sayers’ writing and Lord Peter as a character. It surprised me so much that I knew I had to read the second to see if progress was noticeable - and just by reading the start of this second one it is clear that this is completely different - good, cozy golden age crime fiction as I’d expect, and the character I am fond of.

I was thinking of ‘tw.txt’ to avoid a double T issue… Anyway I’d say the extension and MIME type are important to know what a file (could) contain
https://developer.mozilla.org/en-US/docs/Web/HTTP/MIME_types/Common_types

Reading the original spec, I understand why it should be a .txt file instead of, let’s say twtxt or anything else. In any case it could be nick.twtxt to support multiple users in the same directory.

What is curious to me was the decision at that moment of twtxt [dot] txt. You have the text part twice 🤔. Like mydb.db or eapl_todo.todo. Nothing really transcendental, just thinking out loud.

Always a great feeling when you can solve npm install problems by simply copying over the whole node_modules folder from your own (linux) machine. One of the benefits of developing on a Linux machine I suppose.

You can call it whatever you want, that’s the beauty of it. There is no need to set a “standard” for this. To prove it, I will setup one feed, and name the file “sørenpeter.txt”. 🤭

PhD level science questions? (+1)
niftydude an hour ago
A PhD level science question is a question that can only be answered by scientific research and experimentation.

And no, by “research”, I do not mean googling.

Literally the whole point of a scientific PhD is to perform experiments and study to answer a specific research question that no one has looked into yet.

Whilst ChatGPT can probably can answer “PhD-level science questions” with the same generation of plausible bullshit it answers all questions, I very much doubt ChatGPT can answer PhD-level science questions with any sort of accuracy.

It can’t do that without performing experiments (that in some cases might be complex enough to last years).

Just more of the marketing BS silicon valley seems to be full of these days. Remember when California was actually making products that benefited society as well as making money?

No he jugado tanto el Pokemon TCG, más que en Game Boy y ahora en teléfono.
https://play.google.com/store/apps/details?id=jp.pokemon.pokemontcgp

Es un juego que, al menos en la primera parte, está muy bien hecho, aunque al poco tiempo se acaba el factor ‘wow’.

Como vemos en ‘Leyendas y Videojuegos’, el juego móvil es más una demostración para una experiencia de como sería que colecciones las cartas
https://www.youtube.com/watch?v=zpAZCy8_-UI

Siento que mucha gente va a interesarse en coleccionarlas gracias a este ‘demo’.

In-reply-to » Fuck me dead, what a giant piece of shit. On my Linux work laptop I have the problem that some unknown snakeoil "security" junk is dropping any IPv4 connections to ports 80 and 443. All other ports and IPv6 seem unaffected. I get an immediate "connection refused" when trying to estabslish a connection.

It just worked fine like nothing had ever happened when I booted my laptop this morning.

I like to think of it like this. It takes approximately five months of power, relatively speaking to power, the human brain vs. multiple megawatts hell even multiple gigawatts of power to power even some of the most modest and yet surprisingly complex AI models.

There is something about human intelligence that we don’t quite yet understand, and it isn’t in the complexity or increasing the number of parameters to the order of billions 🤣

@movq@www.uninformativ.de This random comment from another Slashdot article pretry much sums up my view on so-called “AI”:

Elevator music
Tony Isaac 20 minutes ago
If you derive your income from producing “elevator music” you might indeed be in danger of losing that income to AI. Also, bumper music–music used to fill otherwise silent gaps between segments of a podcast or radio show–might be a candidate for AI takeover.
But if you produce real music–music with depth and emotion–your job isn’t going anywhere.
How can I be so sure? I’ve seen the kind of code AI writes. I’ve seen the kind of prose AI writes. Both are amazing, for something computer-generated. But neither would be mistaken for the work of someone skilled or proficient in the art. Music won’t be any different.

@movq@www.uninformativ.de tried translating that and it said Art lover/enthusiast, that could be correct since that despise of the artificial stems out of “Love for the Actual real Art” although that’s a subjective statement in itself; xD duckduckgo’s translation thing spat out “künstliche-Kunsthasser”

Thank you, @movq@www.uninformativ.de! Luckily, I can disable it. I also tried it, no luck, though. But the problem is, I don’t really know how much snakeoil actually runs on my machine. There is definitely a ClownStrike infestation, I stopped the falcon sensor. But there might be even more, I’ve no idea. From the vague answers I got last time, it feels like even the UHD/IT guys don’t know what is in use. O_o

Yeah, it is definitely something on my laptop that rejects connections to IPv4 ports 80 and 443. All other devices here can access the stuff without issue, only this work machine is unable to. The “Connection refused” happens within a few milliseconds.

Unfortunately, I do not have the slightest idea how it works. But maybe I can look into that tomorrow. Kernel modules are a very good hint, thank you! <3

You’re right, it might be some sort of fail-safe mechanism. But then, why just block IPv4 and not also IPv6? But maybe because the VPN and company servers require IPv4, there is zero IPv6 support. (Yeah, don’t ask, I don’t understand it either.)
