finally made this public - been using snowflake IDs in a few projects and figured I'd package it up. rust does the heavy lifting (because I wanted to see if I could do it)

i really think there is legit political space for running on "we are going to dismantle ICE"
How it started vs. How it’s going NOW 👀

Sempre bom lembrar que o fascismo é, psicologicamente, o movimento político dos ressentidos.

Artistas fracassados viram facho.
Uber é quase sempre reaça.
Velho broxa é um poço de ressentimento e ódio.

O fascismo se alimenta disso. Porque dá um propósito, alguém a quem culpar pelo próprio fracasso.
Odeio esse vídeo porque ele me lembra que artistas medíocres ressentidos abraçam o fascismo com tudo

AI efficiency gains are utter and complete bullshit.
WARN filings expose 4.7k of Amazon's 14k cuts last month. 500 PMs were laid off while engineers (1,800 laid off) were hit hardest, mostly SDE IIs which refutes the "management bloat" narrative.

The trend is clear: Big Tech continues to purge junior roles due to "AI efficiency gains."
Amazon cut more than 1,800 engineers in record layoffs, despite saying it needs to innovate faster
Nearly 40% of the roughly 4,700 positions Amazon eliminated across Washington, New York, New Jersey and California were engineering jobs.

Generative AI tools are the blood diamonds of the tech industry. The technology is quite impressive and valuable but the ethics of how it’s made is questionable AF.

Almost every time I start to play with some new programming language I tell myself something along the lines of "I really miss the amazing #Ruby standard library right now!". Ruby is not without its flaws, but the standard library is very comprehensive and one of the best in the industry.

In 1948, President Mariano Ospina of Colombia signed a "tax on single men".

It imposed a 15% income tax for all colombian men above 35 who weren't married. This rule was in force for 12 years.

Traffic to news sites is plummeting as Google has rolled out AI overviews which provides answers without needing to click on links.

Google had no choice but to respond to the rise of tools like ChatGPT and Perplexity but this definitely feels like a snake eating its own tail.

Chatbots are replacing Google’s traditional search, devastating traffic for some publishers.
