Yup. Once it took Vivado 40 minutes just to add one small Verilog file to a project. Not to compile it. Just to add it to the list of project source files, for which it scanned the file for definitions. Each time I edited the file, Vivado s

To my mind, "think of the children" is something I've only ever seen as a motivating force of anti-liberal politics. With liberals saying the "think of the children" argument is a specious, misdirecting, crude app

There's still a market, but when I looked into COBOL work out of curiosity (I've never been anywhere near it in real life), the salaries I found were surprisingly low, compared with common modern languages. Perhaps the old adage &

You can actually use an alternative authenticator app for Microsoft logins. I use Aegis on my phone for it. They don't make it clear in the messaging during the sign-up flow, which just says Microsoft Authenticator everywhere. But wh

That's why I described a not very well known trick that requires just +1 line, the definition of hash(). It's neither fast nor maintainable, it's just a neat hack that gives you some of the performance of hash tables for neg

This branch of the discussion is is about dereferencing on multiple threads concurrently. That doesn't block the application, each mmap'd dereference only blocks its own thread (same as doing read()). In my own measurements with

If you can search (and do other operations) on a linked list, and the lists are long enough to matter, you can trivially speed it up to a fixed-size hash table with hardly any code changes. This: entry = list_search(key, list); bec

In my experience, in the UK, the rental agency required 12 months rent in advance (plus another 2 months rent as deposit) when I was self-employed. They would have accepted monthly rent if I had 5x the annual rent in cash savings, but I di

You're right about the VMM. But three out of those four features: page cache, dynamic I/O buffering and shared memory between processes, do not require that kind of VMM subsystem, and memory-mapped files don't require it for

Those features don't require an MMU. The no-MMU version of Linux has all of those features except that memory-mapped files (mmap) are limited. These features are the same as in MMU Linux: page cache, dynamic I/O buffering, shared

There are many options. Executables can be position-independent, or relocated at run-time, or the device can have an MPU or equivalent registers (for example 8086/80286 segment registers), which is related to an MMU but much simpler.

The AMD Processor Programming Reference manuals are also good for this, if you like complete and detailed. They complement the Intel manuals. Much the material is duplicate because the processors are so similar, but written in a different

ext4 or btrfs won't save you either. Although that bug report is for ZFS on the same SSD as the Windows article (WD SN770), the faults described in the Linux bug report look like would also happen with ext4 or btrfs. So I searched for

That's up to you. But if you have one of the SSD models the article is about, Linux probably won't help. It might make it worse. Linux is beautifully optimised for performance. Linux is more likely to write the same data more q
