sebgan··on The adder at the heart of Intel's 8087 floating-point chip
No immediate questions, but happy to have some great weekend reading. A quick pass through finds one of the best and clearest explainers I've seen. Thanks for this and all the materials you produce.
sebgan··on Solana Drift Protocol drained of $285M via fake token and governance hijack
This is conveniently suspect, no? “Drift migrated its Security Council on March 27 to a new 2-of-5 threshold with zero timelock. That eliminated the delay that would have allowed detection before admin actions took effect.” This was after the perp started working on the heist earlier in the month.
sebgan··on Meta’s live demo fails; “AI” recording plays before the actor takes the steps
I was going to say that’s two minutes I won’t get back (and I won’t) but, ya know, schadenfreude.
sebgan··on F-35 pilot held 50-minute airborne conference call with engineers before crash
Journalistic integrity (or not) arguments aside, that this happened with such an expensive piece of equipment is disappointing. Reminds me of Deal of the Century; “you ever heard of rain??!”
sebgan··on Interesting Look at Algorithmic vs. Floor Trading
Suspension of floor trading (ie real humans) leads to higher spreads and larger pricing errors for treated stocks relative to control stocks.
sebgan··on School smartphone ban results in better sleep and improved mood: study
True, and we considered that. But there are benefits to a smart phone that we also wanted them to have, just not all the time, and it should be easier to make a smart phone dumb than the other way around.
sebgan··on School smartphone ban results in better sleep and improved mood: study
We got phones for our kids primarily to keep in touch when they are away, especially when they have after school sports, at work (yes, even at 14 they can have gainful employment opportunities like reffing soccer). It would be great if the "smart" phone had a true "dumb" mode where the phone basically becomes a Nokia Blue vintage talk / text device. Not an app you have to install, but something that is part of the OS which I, as the parent, can control.
