Big fan of this fork, been using it for everything for the last couple of weeks. Went from codex/claude code -> opencode -> pi -> oh-my-pi

Try Starlink?

Always fun to see one of my professors from the quite tiny, but awesome computer science department at St Andrews on HN!

Sorry, yes, was referring specifically to the Sunil Tagare version.

FYI, this is NOT the cable Facebook is planning to build, this is the dream cable of a submarine cable… enthusiast? From LinkedIn: “To be clear, this is not Meta's plan or map. Thi…

This latest revision of Jupiter is apparently 400G, as is the ConnectX-7, A3 Ultra will have 8 of them!

I’ve heard stories from people who have worked at Hanford, and it seems like a lot of that money is being squandered. Excess caution, basically everything is radioactive waste, and…

There’s more than one slang dictionary, it seems… here’s one I found in person at UCSD’s library: https://photos.app.goo.gl/J3rCLtbJMEn4SkKq8

They called out Flexential in the post?

Pretty wild for a single fiber, but super involved, using 5 different doping type amps. Current systems use just EDFAs (Erbium). These guys used Erbium, Thallium, Bismuth, and othe…

I updated my map for AWS in Northern Virginia -- came up with 74 buildings (another source says 76, so i'll call it directionally correct). If I scale my sq ft by ~5% to account fo…

Well, they tell you for one: https://datacenterpost.com/scaling-up-google-building-four-s... We also have Google Street view, etc. Of course, it's all estimates. You can get fancie…

Yep, I am aware, I have a square footage multiplier for their multi-story buildings.

I’m not sure mapping VPCs is super helpful - the physical infra is fairly distinct. AWS has also disclosed 20 million Nitro adapters have been deployed, so you can do some backward…

Yep.

Google certainly has more compute density than Amazon, the numbers I was able to find from the local power company was 250MW at Council Bluffs back in 2015 or so. Amazon builds out…

To date, facebook has built, or is building, 47,100,000 sq ft of space, totaling nearly $24bn in investment. Based on available/disclosed power numbers and extrapolating per sqft, …

You can just map them all... I have. I also worked at AWS :)

I have mapped every AWS data center globally, and I worked at AWS. Facebook publishes this data.

Facebook has more datacenter space and power than Amazon, Google, and Microsoft -- possibly more than Amazon and Microsoft combined...

Token buckets have burstiness problems, CAKE lets you run things at ~99%+ of your link speed, assuming a stable medium, without bufferbloat, thanks to the packet pacing it does. CA…

I did the math on this back in 2013, based on the annual reported number of hours uploaded per minute, and came up with 375PB of content, adding 185TB/day, with a 70% annual growth…

There's currently a study underway that took 100 people who have been on a low carb high fat diet for, on average, over 4 years. These people had a large increase in LDL when switc…

I didn’t generally see upstream congestion when I worked on Internet QoE at Comcast, downstream was more common. Cable modems do ACK suppression as well to help there.
