If you have a web API that returns a 200 OK with a JSON object with a missing entry when an item is not found, instead of a 404 error, then you have a bug in your API. But you cannot allow it to change because your users are relying on the

The people who matter, who write init scripts, in other words the distro maintainers, were happy to switch. Why else do you think so many distributions switched? Yes, the resistance is noisy and stubborn Unix neckbeards. Not even Unix, sinc

The journalctl binary format seems to handle corruption pretty well. That was a design criteria. Everyone forgets or tries to ignore that text files ARE A BINARY FORMAT. It is encoded in 7-bit ASCII with records delimited by 0x0a bytes. Cor

That isn't exactly switching engines. That's the Vulkan renderer they're working on. It is a component of the same engine they're already using.

LOL! No, the HDD never was reasonably fast. Our expectations changed. I booted up an old Windows XP box about two years ago before recycling it. It took almost TWO MINUTES to finish booting to the desktop. Some kind of fairly standard 500 G

I have a Windows virtual machine that was doing this to me a lot, and making Ubuntu reboots take a long time, and then requiring a disk check after the unclean shutdown. I found a registry key that tells Windows to force stop apps that bloc

Not counting BIOS time it is about 5 seconds to Windows login on my Windows with NVMe systems. It does take about 20 seconds after login for it to finish loading all of the tiny startup notification icons, but that's actually intention

I believe the benefits of cryptocurrency outweigh problems. I like having options that can be anonymous, don't require banks, immune to government influence, and even completely outside any law. Because laws are not always moral and

But it would be transpiled so the programmer would never need to look at the very ugly stuff. The idea reminds me of the original asm.js

Your other choices are: - Never GC via using object pools. This code is nastier than C++ because Java is not intended to be used this way. - GC whenever needed randomly. The game will just pause occasionally. Very annoying as a player. - Wr

It is about making money. Starlink is a money generating system that makes use of low cost launch made possible by SpaceX. If it does use up most of the low orbit space it is because SpaceX is the only company that is even capable of launch

Build better walls. Don't try to outlaw people "looking at you", no matter what frequency they use. I find it equally ridiculous to try to outlaw software radio that might listen to "unapproved" radio bands, or list

Copy-on-write is exactly what G++ and libstdc++ did with std::string before C++11 changed the spec. And it was terrible and full of bugs. I remember how I had to solve a pile of thread bugs in a C++ project by changing string assignments in

Some applications using OpenGL or Vulkan and Wayland compositing end up with latency related to one or two frames of the screen refresh. Which means that characters appear onscreen much faster on a 144 or 240 Hz display. Not really a surpri

I like to nitpick and point out gets() can be used safely, as a stunt. Memory map a read/write page and after that memory map a no-permissions guard page. Now you can safely use gets() to read a page size string without allowing a buff

In relativity, everything is relative. You can choose any "rest frame" that you like and all the math still works out. For the star, from its point of view its mass has not changed at all. So yes fusion still works.

Yes, if allocation failure is not tested, it is not likely to work correctly. SQLite is also famous for its strict and complete test sets.

I have had to help a few Unix newbies, and systemd is way easier to explain than RedHat init scripts with comment blocks for chkconfig and no useful errors if things are wrong. The biggest problem I remember now is that when testing your in

These tools are mostly useless because they take time to discover and learn to use. In the meantime you could have solved the problem. Developers who waste all their time searching for a magic tool are not productive. They're also ofte

Latency often does increase with new generations of RAM. But remember to compensate latency cycle counts with the faster cycles of higher speed RAM. Often the absolute time in nanoseconds hasn't changed as much as the cycle count numbe

From what I have seen the available spare value will decrease rapidly near end of life. As Flash cells start to fail they are replaced by spare. Because of write leveling this is delayed for a while, but then as each cell reaches its 300 or

Many people are happy to save $100 in exchange for not having 8 USB ports. Or $300 to not have dual 10G Ethernet ports. If you aren't getting "adequate rear I/O" then go looking for a prebuilt Threadripper Pro system wit

It is almost 5 years old and several generations back. Perhaps not "ancient" but it's aging. From the 480 there was the 580, Vega 56/64/VII, RX 5700 and now the 6800. From a few random benchmark site checks online t
