Yes, I am seeing otherwise: querying 8.8.8.8 via UDP results in a truncated response packet. Probably the reply you’re looking at is already the TCP-retry response.

TIL: Apple’s migration tool supports Thunderbolt networking, so by connecting two Macs with a Thunderbolt cable, you can transfer data much much faster than with Gigabit Ethernet: the migration tool measures the connection with 3 GB/s peak speed (actual migration speed: >> 500 MB/s):

Went to see Tangerine Dream live tonight! Great tracks, visuals were stunning and overall a good time :)
If you haven’t heard of them: they *defined* electronic music in Germany back in the 1970s and have been active ever since. They made the sound track to GTA V! en.wikipedia.org/wiki/Tangeri...

Any last tips or recommendations before I click order on this PC build?
This will be the replacement for michael.stapelberg.ch/posts/2022-0..., i.e. mostly doing compilation, browsing and similar. Goals are: silent, low idle power, fast.
(I’ll keep using my current nVidia GPU for now.)

Did an analysis of the various go-mail packages in the #golang ecosystem.
Instead of finding “the best fork”, it seems like I’ll need to switch to wneessen’s alternative (not a fork).
Did I miss any significant development here?

New blog post! 🎉 Testing with Go and PostgreSQL: ephemeral DBs
Let’s say you created a #golang program that needs a DB — you installed PostgreSQL, wrote the Go code, and everything works; great! But how do you best provide PostgreSQL to your automated tests?

New blog post! Debug Go core dumps with delve: export byte slices
Not all bugs can easily be reproduced. Sometimes, all you have is a core dump. I had trouble figuring out how to save byte slice contents from memory into a file for further analysis with delve…
