Yeah, that's not a padding oracle, but it's similar in concept, because the prefix check after decryption will likely leak whether the app considers the ciphertext valid, ala: pk = decrypt(params.id) if pk[0:8] != EIGHT_

While AES(0||id) is subject to a padding oracle, it's not immediately obvious why this would be a useful capability to an attacker, since you can't tweak your input based on the oracle's output (unlike e.g. AES-CBC).

Wouldn't this be an excellent use case for Wikidata? For example looking up "sci hub" on Wikidata leads to https://www.wikidata.org/wiki/Q21980377 which has an "official website" field.

In postgres, queries involving aggregates on joins generally seem to result in join-then-aggregate, even if the join is entirely foreign-key-independent of the aggregate.

Forward isolation is not necessarily much better than -60 dB depending on the exact op amp.

Thinkpad microphones are bad regardless of being obstructed. Almost all (I'm sure there's an exception somewhere) microphones built into laptops are pretty bad, and at least half of that is due to "inside the laptop" is

For analog, electret microphones a mute switch is very simple. Simply put an R-C pair (R a few MΩ, C 10-20 µF) in parallel to the microphone capsule. To mute it, short the R out. This is pop-free because the R charges the capacitor to the D

ReaFIR works quite well and has very low latency. It's a bit fiddly to auto-generate a noise profile due to the architecture of Equalizer APO (the entire audio processing runs inside the Windows audio stack, so the VST panels in the co

The current "best case" scenario of your government is 100k-240k dead; less than one order of magnitude is basically nothing in an exponential crisis. 240k to a million is just two doublings.

Use Equalizer APO with a noise-reduction VST. This is by far the best option on Windows if you are concerned about latency×compatibility×underruns as a figure of merit. It is far superior to using "virtual audio cables" and a VS

The 3900X and 3950X sadly still have issues with idle power, the lower end chips do much better. A 3400G for example self-reports less than 10 W at idle, entire system is around 20 W out of the power socket. The uncore of my 3900X consumes

Linux is monolithic, but also modular. While drivers are almost entirely implemented with these kinds of objects, "core" modules have less pluggable functionality, and so you don't see it as much. For example, contrast the pa

The grand majority of code in the Linux kernel will never be hit by booting it in a QEMU with init=/bin/shutdown. The pure line coverage of these builds is probably like 5 or 10 %.

It used to be the expected norm, but nowadays a lot of the larger companies actively say they don't want pics, and depending on job sector, more and more people tend to not include them regardless.
