You can use the kcmp system call with KCMP_FILE argument to find out if two fds point to the same files structure (of course you must use this as the custom comparison function of a sort algorithm so you don't end up with quadratic run

You can do most or all of that by reading /proc/<pid>/fdinfo/<fd> and /proc/<pid>/fd/<fd> or by making system calls on the affected fds (which you can do e.g. by injecting code

It's wrong because it's useless: you can use inline styles instead (and if you gzip the html it's probably going to be smaller as long as you factor in the framework, since essentially you are using numeric LZ backreferences

The "absolute risk reduction" and NNT numbers seem pretty useless, since they are in a context where people are trying their best to avoid getting infected with isolation, masks, distancing, etc. Once the vaccine rolls out, people

Nice, maybe we can start embracing more sensible ways of feeding people that the ridiculously inefficient restaurant model with cooks, servers, individual food choice and individual tables.

How about making a browser in addition to a "rendering engine for embedding in other applications", in the form of a standalone program and/or a Firefox (desktop and mobile) fork that can use Servo as well as Gecko? You could

It might be time to introduce a protocol that allows networks to display authentication prompts without needing to MITM HTTP connections. It's not even hard, all that's needed is to add an "authentication URL" field to D

The alternative is a high chance of becoming ill with COVID, which according to the data available so far is much riskier than the vaccine (1-2% hospitalization risk even for healthy young adults, evidence of long term issues at least in so

I would expect vaccination to be fully booked for a while, since it's going to be the most important thing in life to do for anyone not suffering from other serious issues and without anti-vaccination beliefs.

The proper solution is using well-designed GraphQL-to-PostgreSQL software like Hasura or PostGraphile. There's no reason to use Rails for that (or, well, use it for anything at all, given the terrible language it's based on and it

Do you know of any ANC solution that works well (i.e. should be much better than foam earplugs, and preferably remove all sound no matter what) and is usable for sleeping?

The simplest would be to weight one's vote by some non-decreasing function of the number of people who live in the same conurbation. That would partially achieve the outcome and also makes sense, because if someone wants to live in iso

It's pretty remarkable though that almost half of the US voted for someone who is clearly unsuitable to be president based on his first term. It might be time to consider letting go of the democratic ideal that every person's vote

That doesn't work because async functions need to be compiled for minimal stack usage (i.e. segmented stacks, packed variables), while non-async functions need to be compiled for minimal CPU usage (i.e. no stack checking or allocation,

The real issue is the lack of dependent types in Haskell (and unfortunately Rust and all languages with a vast ecosystem). With dependent types, you can just include a type-level proof that x <= 5 in the integer wrapper type, which then

This is just a tooling problem that can be solved trivially by having release builds build multiple binaries by default, for all the major extension profiles.

No, Visual Basic 6 can only place controls by X/Y position, has no databinding and no VDOM or way to create controls other than placing them in the designer or manually creating and destroying them in code. It's pretty terrible un

LLVM undef does not mean "undefined behavior", it means that it's OK to transform any use of it into the use of an arbitrary value (potentially different, unless the freeze instruction is used). To get undefined behavior, you

I mean taxes on all carbon emissions should be raised (if airlines already pay them, otherwise airlines should pay them - also "taxes" can be replaced with a cap-and-trade scheme).
