Ready for #FOSDEM: got some hardware to talk about, and some local beer to drink.

If I have any RDNA4 experts here, what’s the deal with SCC for min/max instructions? The two columns here seem inconsistent.

Flying in for Tenstorrent developer day: first a comedy turbo-prop plane, then a proper full-size plane (taking advantage of Dublin’s ability to go through US CBP whilst still in Europe).

I remember when this was but a wee LaTeX file. But look at this, it’s now all grown up and printed.

As an appreciator of stack unwinding esoterica, it’s been a good couple of days. First the Cloudflare Go writeup, and then github.com/llvm/llvm-proj… rocks up in my inbox.

Starship so heavy that it causes 8 minutes of time dilation between launch site and Greenwich? Seems kind of sus, but Wikipedia would never lie to me…
