> Taxis are almost always twice or sometimes (airport) 3x the price. Not where I live. Here, Uber is 50-100% more* than the price of a local taxi, at all times of day. Uber is also at least 30% more expensive than hailing a black cab.

The trick is called the Fiat-Shamir transform, and you're right, it does require more questions to get an equivalent security level, precisely because you can try a large number of random non-solutions without anyone catching you doing

I have a Macbook and an Android phone, as do many people. Can I still have a seamless experience with passkeys, or have they made that difficult? Do I need to remember to reject the dialog offering to save keys on Keychain and learn to use

I find it's worse with Chromium than Firefox. After an update, new tabs don't load properly and links fail, until I manually restart it. In the past I've joined Google Meet meetings in Chromium and found the audio not worki

Especially when it asks you to do it again, and again, until you realise you're never going to be allowed to see the page. I've had that happen a few times with sites behind Cloudflare.

Fwiw, I've had a similar screen issue (turned green or magenta and glitchy, parts of the screen image disappearing, until one day it turned black) happen with two Samsung phones.

Not when it comes to capital assets. The full cost of a large capital asset is generally not allowed to be treated as an expense for tax purposes. It's technically correct that tax is levied on "net income", but that's

Wow, there are a lot of C compilers for Atari ST! I was astonished to find about 22 distinct C compilers, including their own libraries, assemblers, linkers etc. for the Atari ST and its successors. That's not counting separate versio

Round trips for parallel requests work fine over HTTP/2. (As long as there aren't vast numbers of tiny requests, for example every cell in a spreadsheet). However, sequentially-dependent requests are about as slow with HTTP&#x2

Since you asked, yes, optical flip-flops have been around for decades. That said, you don't need flip-flops or latches to calculate SHA-256 for mining Bitcoins. You only need them at the edges of the circuit, to use the results. But

Last time I measured on Linux (a few years ago), with NVMe, mmap + calling out to a thread pool to async-page-touch (so the main thread didn't block) was faster than io_uring (from the main thread) for random access reads.

Sure you can. The services just need to agree protocols. The tech & cryptography part is not difficult these days. We've had guaranteed E2E for email since PGP in 1991, though not many people cared enough to use it. None of the ser

Actually, F-Droid has quite strict requirements on the apps it will accept, and it enforces them. Low-effort spammy apps with ads and in-app purchases are unlikely to be accepted. Standard Android in-app purchases, efficient notifications,

Linux in Android is GPLv2 not GPLv3. The v2-v3 difference is a big deal to some. Linux developers made an intentional decision to stick with GPLv2 and to remove the "or later version" option, so you can't include it into GPL

The gprof profiler was used long before 1993. It dates back to 1982. I did game engine dev professionally in 1994 (and non-professionally before that). We profiled both time and memory use, using GCC and gprof for function-level profiling

The compact one-liners below are similar but avoid adding duplicate items to PATH, so are fine to call in various init scripts. In Bash: path_append() { local p; for p; do [[ :"$PATH": =~ :"$p": ]] || PATH+=:$p; done

const is different in C++ from const in C. const variables in C++ are proper compile-time constants. In C they are not (the nearest equivalents are #define and enum values). So in C++ "const x = EXPR" would make sense to request

WhatsApp on Android has the same behaviour. Most of my conversations show as a bare phone number because I decided not to give it all my contacts. However, WhatsApp groups show a name, so that's a workaround if you are using WhatsApp w
