You kinda want some machines to reboot less frequently than others, so issues don't creep up on you. You also want some machines to reboot much more frequently than others, so you catch boot issues before they affect your entire fleet.

It seems most likely that the corruption happened in RAM or the local storage device, after the TLS integrity check had already happened.

I haven't looked but I bet a lot of the WAL complexity comes down to supporting consistency and durability guarantees, neither of which you necessarily need for your in-browser use case.

Reminds me of the Royal Society's contributions to science - we benefited from a bunch of landed gentry with time to spare, keen to self-actualize. (Stallman had that MacArthur Grant, too!)

Back in the 2000s the Australian government provided software that ran on Windows to prepare and submit your personal tax return. I used to archive my tax return by preparing it in a Windows VM, then storing the whole VM image.

I wonder if 200 KB is small enough that TCP slow start will be the constraint on a download over a new connection, rather than the bandwidth.

Looking forward to the point where this can build autoconf. It's great that the generated ./configure script is portable but if I want to make substantial changes to the project I need to find a binary for my machine (and version

Something I didn't realize before trying one is the different assist settings available. The lowest one just made it feel like I'd slept better and was having an easy ride. The highest assist setting had a really obvious "kic

Interesting you should mention inputs. One of the things I’ve often found useful to log are the data that are inputs into a decision the code is going to make. This can be difficult to reconstruct after the fact, especially if there is a ca

Agreed you need to engineer the logging system and not just pray. "The log service slowed down and our writes to it are synchronous" is one I've seen a few times. On "do not consider what to log and when" .. I'

As an engineer I generally want logs so I can dive into problems that weren't anticipated. Debugging. I get a lot of pushback from ops folks. They often don't have the same use case. The logs are for the things that'll be esc

There's a warning when you step off the airplane onto the jetbridge at SFO. Good luck refusing to get off the plane because you see the cancer warning and decide not to risk it.

From the file linked in https://www.vogons.org/viewtopic.php?p=534845#p534845 , it looks like 'mov fs, ax' may have been 5 cycles compared to 3 for 'mov dx, ax', with no penalty in the other direction? So

Quake didn't even present the bitmaps in a consistent aspect ratio or size, it did a 1-to-1 pixel copy regardless of the target pixel shape/size. Quake shipped with a 320x200 default resolution in 1996, with configurable support f

It'd be interesting to benchmark this on texts from different languages. English text will be very friendly to the branch predictor because it's all 1-byte codepoints. I think a language dominated by either 2-byte or 3-byte codepo
