Debian is super good for this. Most of their apt mirrors are still up and running, so you can easily download and build software from 2002 if you use the appropriate Debian release to do it.
I usually do this first to make sure the software builds and works, then I try to figure out how to get it working on a newer OS.
Fun fact, Cisco actually owns the trademarks to iPhone and IOS and licenses them to Apple[1]. IOS is their famous operating system and iPhone was a product offered by Linksys which they acquired when they purchased Linksys.
As an aside, many full service banks can exchange foreign currency for you. For example, Bank of America does (https://www.bankofamerica.com/foreign-exchange/exchange-rate...). You can also order foreign currency prior to your trip and they'll mail it to you.
Interestingly in my country many full service banks have dropped foriegn currency services. They did that during the panademic but never returned back to offering that again. I suspect they make so much money from Visa/Mastercard commissions that they'd prefer people paid with card rather than cash.
Right, it’s the same here. I learned that the hard way. If I ever need cash for traveling again, this is the way. I much rather use credit card if I can, however. But this place didn’t even had cell phone signal, so accepting anything other than cash was impossible.
> sds.total_pwr is the sum of the power of all CPUs in the scheduling domain. This sum ends up being zero and that’s what causing the crash – division by zero.

The author doesn't really describe how this panic is related to uptime. Do long running kernels collect a lot of real-time tasks, is it a leak of some kind?
The suggested fix link doesn't provide any extra context as to why its uptime related either.
BinaryNinja does this. They have several layers of intermediate representations[1], which they build their compiler on top of. Ghidra does something similar with their PCode. They disassemble to PCode and then decompile the PCode[2].
Articles of Interest is _so_ good. It's a great take on the 99% Invisible "design of everyday things". I was definitely blind to clothing and textiles and Articles of Interest is really enlightening.
You may enjoy Search Engine by PJ Vogt[1], it's really well done. Its the quality of the original Gimlet Podcasts and a bit different than his previous show (Reply All).
