Meta built tools so tightly connected that changing code felt almost automatic. Tomas Reimers explains how they broke big changes into small steps, used automatic rules to catch risky edits, and why AI writing more code makes careful checking even more important. youtube.com/watch?v=qBRJxIw7… What would you start with this week: timing how long changes sit untouched, auto-alerting the on-call on risky edits, or showing live status right on the change request?

Last thought: The liquidated damages clauses of the contracts between neoclouds and their offtakers will be the final boss battle. If you don’t have experience building highly available compute, you will have outages that stress your uptime commitments. If you can’t remedy them, your offtaker will be extremely punitive. Terms that look good on paper now starts to shrivel under the LD terms of offtaker contracts. You’re already starting to see a few of these blow up - you lose your IG wrapper, a big hyperscaler dumps you etc etc. So anyone in the data center game needs to ultimately be excellent at management/uptime/maintenance. If you’re not, you may wilt when you inevitably have to manage some moment of downtime.

There's a bit of chatter about Monorepos vs Polyrepos. Obviously there is a strong correlation between marketcap and monorepo, which is an argument from authority not a technical argument. If you have 2-4 repos then you'll struggle to see the benefit of merging. But when you have dozens or hundreds, you will. Default to a single repo and carefully measure friction if you create more.

Chamath reveals a major US bank cut AWS and Google Cloud spending and built six independent data centers, because companies increasingly want control over their own data “I see that at 8090 as well. I think the large companies that we work with, you can almost pinpoint it on a chart. Ever since Alex Karp’s commentary on CNBC about data sovereignty, buying patterns have changed. And I think people are being a lot more methodical. “They are building out their own data centers, or at least moving into VPCs, virtual public clouds. My team yesterday was at the CIO event of, let’s say, one of the largest banks in America. “You know what they said? I’m not going to say the name of the bank. It was the most incredible thing. They said, ‘We have decreased our spend on AWS and GCP. We now have six completely independent ground-up data centers that we’ve built from scratch for ourselves.’ “And I was like, ‘What is going on here?’”
Chamath explains how VC funding circularity is giving AI the diffusion problem Ken Griffin is picking up on “So the cycle here, just to be very precise, is VCs raised from pension funds and LPs and foundations and family offices. They put money into a startup. That startup takes that money and invests in growth. Part of growing is by consuming other people’s AIs. And so that company then starts to show revenue traction. Those folks then say, hey, look how well we’re doing, raises a bunch of money from the same VCs. And it’s just this circularity.” “Why that’s important is what Ken is pointing out is that for AI to really scale as a predictable driver of long term earnings, it has to diffuse out of the startup ecosystem. And so you can’t be in a situation where on the one hand, you’re talking about breathtaking valuations. But we’re 75 cents of every dollar is actually just a startup sending it back and forth so that they can mark themselves up. That’s, I think, a structural problem.” “But the difference there is that AWS was abstracted from Amazon retail, which was already then a roughly breakeven profitable business, at least on a free cash flow basis. So what’s different here is you have a bunch of money losing entities just spinning a bunch of money around and it has to diffuse more broadly.” “They said, we have decreased our spend on AWS and GCP. We now have six completely independent ground up data centers that we’ve built from scratch for ourselves. And I was like, what is going on here?” “AI has a diffusion problem. It is too concentrated and ripping around in a small little ecosystem. We need to diffuse out. But as it diffuses out, people are picking open source is what I would tell you.”

Odd that people are mad about gene editing dogs. We have a pedigree CBR with bad hips, a heart murmur and weak knees (1x tplo). The breader clearly wasnt the best as these things shouldn't all happen. Destroying (murdering) puppies isn't the answer either. Gene editing is.

Amazing how quickly we went from "oh no LLMs are going to flood the Internet with insecure code" to "oh no LLMs have discovered the internet was already flooded with insecure code"

‼️ BREAKING: The private keys of 8 certificates from Indian certificate authority eMudhra were compromised, Mozilla says. Firefox blocked them within 3 hours. Each key should be a 116-digit number, but one was just 4. Anyone can guess them and forge HTTPS certs for any website.

High achievers have a completely different mindset. A lot of the time you'll feel like the odd man out, because you just see things differently than the people around you. You're usually the one asking why everyone does it this way, or why a process even exists in the first place. You zig while everyone else zags. People will question your methods for a while. Once you're proven to be an A Player, they'll pretty much let you do your thing.

Ai development has made computing fun again. Almost like the early internet when people would throw little cgi-bin toys up, and email was a huge novelty.

If we attempt to outlaw AI, we won't prevent it from being developed. We'll just ensure that the development is done by the most ruthless and careless possible people - criminals and governments.

From concept to reality. @SpaceX has successfully deployed Starlink V3 satellites into Earth’s orbit and made contact with them for the first time. At scale, one Starship carries 60 V3 satellites, the same network capacity as about 20 Falcon 9 launches.
