Agree with your pain points. One thing id add is GitHub makes you reapprove every PR after each push. As an OSS contributor it’s exhausting to chase re-approvals for minor tweaks.

mmmm this is up to each repo/maintainer's settings.

To be fair you don't know if one line change is going to absolutely compromise a flow. OSS needs to maintain a level of disconnect to be safe vs fast.

I'm actually sad by this because it was such a place that was so foundational my development as an engineer. I visited it once in last month or so, when I had an AWS Lambda - Playwright issue that need specific settings to solve the problem but Claude, Gemini gave me a mash of the answers. I'm not complaining, but I "grew up" with Stack.

Our space no longer looks like a pyramid, I liken it to diamond-ish. New grads will simply not be able to find jobs[0] and I'm worried for anyone entering the E in STEAM (can't speak for others).

It's happening now and we're only at the tip of the iceberg. I have 2 young children and am uncertain about how to help them navigate the future.

The sword of efficiency doesn't care about my children. I mean that's my whole job right? to help people become efficient? It's just the speed and scale is insane.

More questions than answers...

irjustin commented on OpenAI's ChatGPT Agent casually clicks through "I am not a robot" verification arstechnica.com/informati... · Posted by u/joak

This will be one of the big fights of the next couple years. On what terms can an Agent morally and legally claim to be a user?

As a user I want the agent to be my full proxy. As a website operator I don’t want a mob of bots draining my resources.

Perhaps a good analogy is Mint and the bank account scraping they had to do in the 2010s, because no bank offered APIs with scoped permissions. Lots of customers complained, and after Plaid made it big business, eventually they relented and built the scalable solution.

The technical solution here is probably some combination of offering MCP endpoints for your actions, and some direct blob store access for static content. (Maybe even figuring out how to bill content loading to the consumer so agents foot the bill.)

real problems for people who need to verify identity/phone numbers. OTPs are notorious for scammers to war dial phone numbers abusing it for numbers existence.

We got hit from human verifiers manually war dailing us, this is with account creation, email verify and captcha. I can only imagine how much worse it'll be for us (and Twilio) to do these verifications.

The California Memorial Stadium is built directly on a fault line, right?

irjustin · a month ago

Guess we'll get even better videos then.

I know nothing so help me here. Why is this so rare? Aren't earthquakes, cameras, and monitoring of them pretty common?

irjustin · a month ago

Videos of earthquakes are common enough.

It's the video of the fault line itself fracturing that's so interesting.

We know where the fault lines are, so we generally avoid building anything major near them because... well earthquakes. Hence no other videos of actual fault line fractures (vs general street ones).

The phoebus cartel whine is bullshit - incandescent light bulbs should be limited to 1000 hours because 1) the cost of electricity used by the bulb is easily as much as the replacement bulb (in the 1920s/1930s), and running the bulb hotter makes it more energy-efficient, and 2) because running incandescents cold makes the light look sickly and awful. Light bulbs were mostly being sold by electric companies at the time, so trading one for the other didn't matter to them.

Planned obsolescence does happen, but the phoebus cartel is the worst 'example' of it.

irjustin · a month ago

It's fine to complain it's a bad example of "planned obsolescence", but I hope you didn't downvote me for that (i got a few downs).

I was just talking about organization of competitive companies for price manipulation, but specifically controlled for the benefit of the public - such that we don't lose the US plant due to natural market forces.

It's why ULA is still in business despite SpaceX being significantly cheaper.

If something happens to Taiwan, we won't regret being able to produce these chips domestically. If AI keeps growing like it does, it might even trigger a conflict.

irjustin · a month ago

Is something the gov should subsidize or at least organize competitors to act like a cartel[0]?

Such that the market forces don't push pricing that the plant would naturally die.

An an EV owner, I can testify that the tyre wear more than makes up for the reduction in brake dust. I’ve had to change tyres every 10K miles.

irjustin · a month ago

How is tire wear related to the method of power? It could be a steam engine for all it mattered.

Accelerating and decelerating, in regards to the tire, don't care what is causing the force.

More hype than substance unfortunately.

The AI rediscovered an interferometer technique the Russian's found decades ago, optimized a graph in an unusual way and came up with a formula to better fit a dark matter plot.

irjustin · a month ago

Ehhhhh, I'll say it's substantive and not just pure hype.

Yes the AI "resurfaced" the work, but it also incorporated the Russian's theory into the practical design. At least enough to say "hey make sure you look at this" - this means the system produced a workable-something w/ X% improvement, or some benefit that the researchers took it seriously and investigated. Obviously, that yielded an actual design with 10-15% improvement and a "wish we had this earlier" statement.

No one was paying attention to the work before.
