In so far as bracing for draconian tracking, I already would have never worked for Meta and especially wouldn’t now. I think we can vote with our feet and not work for companies that do this.

Sounds like something we should study more rather than dismiss.

What struck me though is that OP did so much work to migrare the server with zero downtime. The _single_ big server. Something’s off here.

To give them some credit, they support both positions because they were told to support them by the same people and never put much thought into it.

And I’m so glad they did. Tiktok has brought so many positive changes to my life, and it never would have happened if they hadn’t built a product so good that it’s literally addictive. I don’t want the government to be my parent.

Additionally, Instagram and Facebook have tried their best to make their products as addictive as possible, yet their recommendation algorithm is so absolutely terrible (not to mention their ads) that I barely stay on the platform for five minutes when I use it.

Then why is he listed in that table? I don’t get it.

I hadn’t, and your article lost me there to be honest. You didn’t explain the what, why, or when behind it, and it didn’t make sense to me at all. That said, I’m abnormally horrible at math.

As always with these types of things, it starts off well and I think “wow! finally someone is explaining math in a simple and straight forward way I can understand!”. And once again, they already lost me at Gaussian elimination.

>Powerful stakeholders are typically so stupid and dysfunctional that it’s effectively impossible for you to identify their needs and deliver solutions to them

I’m sorry, WHAT? How old is this author? “I fail to communicate effectively with anyone who isn’t an engineer because I lack the required empathy and perspective” is very different from “the average stakeholder is stupid and dysfunctional”. I stopped reading at this point because author is clearly someone who doesn’t take responsibility for their own failures in communication.

Isn’t that basically what the ARC tests are?

It’s also really good for me as a very senior engineer with serious ADHD. Sometimes I get very mentally blocked, and telling Claude Code to plan and implement a feature gives me a really valuable starting point and has a way of unblocking me. For me it’s easier to elaborate off of an existing idea or starting point and refactor than start a whole big thing from zero on my own.

This may be true, but what I said remains true and it’s a vulnerability that the world needs to fix. Too much power is centralized in the US.

rzz3 — Wed, 06 Aug 2025 07:19:05 +0000

That’s a big flaw. The US needs to stop being at the center of everything, and now we can really see the vulnerability it causes. I hope this becomes an impulse to diversify research funding more.

My coworkers/partners and I haven’t stopped talking about it for weeks. I’m one of them I guess, but we’ll see. The ARC graph I saw, if accurate, is really incredible.

I recently created a new Cloudflare account for a project I’m working on and moved two domains into it, and the settings were both on by default without asking me about it at all. The original press release specifically mentioned enabling it by default.

> Cloudflare, Inc. (NYSE: NET), the leading connectivity cloud company, today announced it is now the first Internet infrastructure provider to block AI crawlers accessing content without permission or compensation, *by default*.

Huge revenue sure, but at what cost? Models should be able to be trained on anything a human can read and see without paying.

I hope they realize Cloudflare opted them in to blocking LLMs.

Ah TIL. These are tiny models though but maybe it’s a good sign.

They hate AI it seems. I don’t see them offering any AI products or embracing it in any way. Seems like they’ll get left behind in the AI race.
