Just to add a clarification for the rest of HN, since this is a common source of confusion... Every cancer has gene mutations. Typically these mutations are only present in the cancer cells and are not there from birth. They don't indi

Does anyone know what's the current consensus about PCG vs xoroshiro. I remember that the xoroshiro author had several complaints about PCG but I don't know ifhe is right or if he was just being salty.

But is this still as important if the executable in question is part of the Linux distribution? In theory, Fedora knows know that Clang depends on LLVM and could automatically rebuild it if there was a change in LLVM.

As Serge Guelton said in a followup email, one of the reasons that Linux distros use dynamic linking is to reduce the disk usage and bandwidth requirement for updates. Technically speaking, would it be possible to design a Linux distro so t

I also don't get it. An NFT is basically a small piece of text on the blockchain saying that you own the thing at a given URL. It doesn't mean you have copyright over the relevant intelectual property. There's nothing stoppin

I'm curious how much battery the video streaming would use here. Wifi tends to use a fair bit of power.

To add to what you said: the HTML specification has a bunch of rules to say how to parse a tag that doesn't have a matching close tag. These grew organically based on how browsers responded to malformed documents. At some point the rul

Worse than innefective; some studies have found that the HCQ arm fared worse than placebo. Not to mention the more fantastical misuses out there, such as nebulizing it straight into the lungs.

In OP's case, the individual functions are replacing small fragments of code that would have been basic blocks inside a larger function. The tail calls are replacing gotos. Those things also wouldn't have produced a stack trace. T

You can still use this trick in C++ if you ensure that the return statements are outside the scopes that have the RAII objects. It's awkward but it's better than nothing. https://godbolt.org/z/cnbjaK85T

On the matter of portability, I wonder if it would be possible to use some macro magic and/or a code generator to convert the tail-call version back into a more traditional while/switch loop, for the stack-based architectures. Whi

Unfortunately, I think that only structs with at most 2 words are passed via registers. Larger structs are passed via the stack. https://godbolt.org/z/frof3xjhW

A very interesting trick! In my opinion, the big takeaway here is that if you are willing to write your C code in tail call style, you can get a lot of control over which variables are stored in machine registers. In the x86-64 ABI, the fir

Only if the alternative is non-tail function calls. Often the alternative to tail calls is a while loop, which also doesn't leave a stack trace.

On the topic of string research, one excellent reference that someone recommended to me is the book "Flexible Pattern Matching in Strings" by Navarro and Raffinot. One of my favorite things about it is that it has a "phase ch

The difficulty adjustment ensures that, on average, there will always be 6 bitcoins minted every 10 minutes. If the price of the bitcoin increases, miners will be willing to spend more energy to chase those 6 bitcoins. The end result is the

If the only argument in favor of the death penalty is that the prison system is inhumane, to the point that someone would rather die than go through it, the answer to that should be to make the prison system more humane.

Framing this as a left vs right issue is an USA-centric way to frame the question. Consider how the US is basically the only country in the american continent that still goes ahead with capital punishment. Most other countries in the contin

The alternative also being barbaric doesn't make the death penalty less barbaric.

Why does the plight of Brazil have to be a magnet for all manner of denialism to show up in the comments? Ivermectin doesn't work, just like Hydroxichloroquine doesn't. Seriously, if these things actually worked wouldn't it b

It's hard to believe that you are arguing in good faith if you're trying to suggest that Brazil is anywhere close to doing well when it comes to COVID.

Intensive care units are at over 90% capacity in most of the country, even after taking into account the recent expansions in the number of beds available. Even if we had all the money in the world, there are not enough doctors to take care
