Watch out for its plasma attacks when the beat drops!

JS is the only lang where I would suggest rolling your own dates/times, or passing around ISO strings. Both Date and Moment are filled with traps, and make the fundamental mistake of not having separate date and time types.

Absolutely! If the standard is finding someone you agree with on all issues, you'll find none. I don't label myself a progressive, but anyone who supports ideals and doing what they think is best for the people has an advantage over one beholden to corporate funders.

For the confused commenters: It's like spam mail/email, but they distribute it by throwing it onto your driveway/yard. And the local/state etc governments should stop it and fine+prosecute, but aren't.

The Expedition 33 soundtrack may be my favorite album. The Une Vie trilogy, in particular, are masterpieces.

Unitless are the ones to watch out for! Radians are projected from a more perfect cosmos, but lost their units as a consequence of existing in ours.

It is wild reading how into the Agentic Future communities like HN have gotten. Swamped with true believers. It feels like a religion or cult.

I think this, accidentally, will trigger a defensive reaction in some social science academic groups: When you remove autonomy and personal agency, they will oppose the view based on the conclusion alone.

Same observation! It is also wild whenever I try a simpler editor (recently: Zed), and note it can't do basic tasks like move structs and fns.

It is wild seeing how people on Hacker News discussing Claude and agents. Doesn't match my experience, which is similar to yours.

I do the legit use case you mention. The illegit one looks more fun

Go home clippy, you're drunk!

We hold ourselves in the US to a higher standard. The world now and through history has had more brutal leaders, more government-led violence. Authoritarians are common. That is no excuse for tolerating that behavior here; it's what sets us apart, and what has made me proud to be a US citizen.

ICE just gunned down ANOTHER person, beating a man half to death before shooting him at point blank range. What the fuck are we doing?

ARREST ICE NOW. PROSECUTE ICE NOW.

I will not rest until every single one of these murderers is held accountable to the communities they terrorize.

Observation: The big companies are mostly lowest-common-denominator; the most interesting stuff is consistently from small and medium shops. They can afford to take risks, and be creative! No MBAs correlates to better games!

At about the 35-second mark the officer says "IF YOU FUCKING MOVE I'LL FUCKING TASE YOU," followed immediately by "GET OUT OF THE FUCKING CAR RIGHT NOW."

Which contradictory order are you supposed to follow, knowing that either could get you tased? Or worse?

Implicit in this is that personality traits and aptitudes don't change. That alone is a hell of a topic!

Nothing the Trump admin and his private army are doing is novel or unusual; they're just below the standard we have held ourselves to in the US.

This is what they’ve wanted all along. This is the goal.

Non-protesting dad just trying to hustle his kids, as young as 6mo, out of the neighborhood. ICE threw a flash-bang INTO HIS car, all 6 kids in the hospital now.

If anyone wondered how things turn against occupying armies there's a case study playing out in front of you.

🚨"This is nuts! What the f*ck is going on, this is insane! ICE is just trying to scare people; they tell you it's only immigrantsβ€”it's f*cking anybody!" -furious Minneapolis resident tells our @zdroberts.bsky.social after ICE shot a man in the leg tonight. LIVE NOW ⬇️

This is a dichotomy in propaganda that's universal, but I don't understand. I believe it's a "use broadly positive descriptors for us; negative for them", regardless of mutual consistency. So, here, "victim" is a positive descriptor, so they apply it.

This apparently works, as it's ubiquitous.

The video also allegedly shows the CBP agent saying β€œDo something, bitch” before shots were fired. In private Signal chats, the CBP agent boasted to other officers: β€œI fired 5 rounds and she had 7 holes. Put that in your book boys.” If he felt comfortable enough communicating that to fellow employees, it speaks to an irredeemable organizational culture.

This is the second time in three months a DHS agent called a US citizen a "bitch" as he shot her. donmoynihan.substack.com/p/whos-threa...

Yes, JD. Let’s ask them if they think a stay at home mom, avowed Christian, and widow of a veteran deserved to be shot in the face and left to bleed out in her own car after dropping her 6-year-old off at school, for the crime of looking out for her neighbors. Let’s ask everyone running for office.

We must re-introduce the word *lie* into our vocabulary when appropriate.

A 6-year-old just lost his mother. A woman was shot in the face in front of her wife.

The swift, lockstep attempt to dehumanize and villainize Renee Nicole Good might be the most depraved thing we've seen yet from these ghouls and their supporters. These people are utterly fucking dead inside.

We’ve seen this in Chicago. Now we’re seeing it across the country.

ICE is a lawless secret police force and must be abolished. This is fucking horrific.

Of those, Engine programming is a good fit; I do a bit of embedded, and non-game 3D graphics
