An obscure quirk of the /proc/*/mem pseudofile is its “punch through” semantics. Writes performed through this file will succeed even if the destination virtual memory is marked unwritable. In fact, this behavior is intentional and actively used by projects such as the Julia JIT compiler and rr debugger.

Upgrading to a regular paid account (which still gives you the free tier credits), you get a selection of VMs. New this year are the AMD EPYC Turin Standard.E6 VMs and the next generation ARM Standard.A4 type powered by the AmpereOne M CPU. If you recall from last year, the AmpereOne A2 instances were slower in quite a few tasks than the older Altra A1. Ampere really needed a step forward, and AmpereOne M (A4) finally delivers meaningful gains in this year’s dataset. I had trouble building older-gen AMD instances, so in the end I did not include them. I also could only build Standard.A4 in one region (Ashburn), even though I tried in Phoenix which Oracle had in the availability list, to no avail.
