I don't agree. I watch YouTube tech, math, and science content every day and that's not my experience. There are a small set of products that seem to be everywhere for a while, occupying a minority of sponsor segments. But in most

You would usually do it for performance rather than RAII correctness. For example, without GC, your library might use RAII with std::shared_ptr, for certain objects that outlive lexical scope. That is, reference counts tied to pointer copie

It's worth asking. When I did, they couldn't guarantee to repair my 2013 laptop, but they sent out a parts request to see if they had a replacement part in the warehouse (top case), and they did have one, and they were happy to us

I'll add, when Barclays rejected the business address, that wasn't for a new account or change of address. It was a very active account nearly 10 years old, and the address never changed in that time. It was just a weird surpris

Last time I opened a personal bank account with a high street branch was 25 years ago, and I think I took my birth certificate. These days, looking at the Barclays list from the sibling comment, I'd use a letter from HMRC, which I have

For me, a.big surprise about Incognito mode after using it was finding, by chance, that opening new Incognito windows did not create separate, new private browsing sessions. I was very surprised to open an Incognito window and visit a site

Unfortunately I had a similar thing happen with my Revolut account as people are reporting with Wise. Revolut blocked my account when it contained the money I needed to pay a bill, and it took 5 days to unblock the account with atrocious cu

PCs and Windows are not synonymous. PCs didn't start running Windows until they were nearly 10 years old, and then Windows was just an option. Shortly after Windows became popular, Linux emerged too and some people were running Linux o

Are you sure about that 2017 Macbook Air? I have a 2013 Macbook Pro and I'm getting the battery replaced next week by Apple. My laptop is over 10 years old and they're still doing it at their standard battery replacement price.

Wi-Fi™ was never intended to describe anything. It is a commercial trademark brand, chosen to sound good and be easy to recognise. There's a Wi-Fi™ logo too. In a similar way, ThunderBolt™ links don't use thunder, or bolts.

Calls to printf() are particularly common in signal handlers I've seen in commercial code. malloc() too occasionally. Sometimes calls to logging functions These are undefined behaviour, for real (and for good reasons), not just theoret

You could have each thread select(), poll(), or read() a byte, from the same pipe in their SIGSEGV handler. (Those syscalls are async-signal-safe in POSIX.) When it's time to resume, the GC unprotects the page then writes a byte (or en

They are similar but it's different from Linux, which uses a better workflow than stacked diffs, imho. In Linux kernel development, a PR is a sequence of commits that are reviewed both individually and in aggregate. The major differen

QUIC is roughly TCP-equivalent not HTTP-equivalent, and we do have a BSD sockets API for TCP. You might be thinking of HTTP/3 rather than QUIC; HTTP/3 actually is HTTP-equivalent. You can turn the OP's question around. Ever
