Nope, they solve different problems. The OS package manager (apt, etc) is there to provide you the OS install with a set of applications and a set of libraries to support those applications . Your development, on the other hand, will dep

Reactors? The article doesn't mention any reactors. If you're talking about radioisotope thermoelectric generators (RTGs) used on spacecraft, they are limited to deep space (Voyager, Cassini, etc) and long duration planetary missi

What advantage would an autonomous passenger airliner provide? By removing the cockpit and the pilots, you get a few more passengers and perhaps a few premium priced seats at the very front. The cost of having the pilots in the cockpit does

Afaik LLVM/Clang doesn't need bootstrapping from source for cross-compiling, but you can choose to include/exclude target support at build time. GCC and binutils can only have one target. Was the LLVM/Clang build done fo

You know what, I'm not actually sure. All I know is that it screws up your stack frames. I think I had to provide -mno-redzone on GCC command line. It's something in the ABI (I was on x86_64, the ABI is rather complex) related to

I wear earplugs when commuting in the bus. I take a city bus that drives 80 km/h on the highway and the noise is deafening. If you'd work in that environment, ear protection would be mandatory. I can't imagine how awful it fe

First of all: that technique is not very accurate, calling sleep() is not guaranteed to return in a specific amount of time. But more importantly, that only covers the basic timing attack side channel and not even that very well. Cache and

Linux considers syscall API stable and there's a pretty hard rule of not breaking user space.

The amount the horses poop while doing work is completely negligible. We did haul a big cart of manure from the stables, like half a ton or so. Yes, manure is a good fertilizer and promotes a good ecosystem of microbes but it needs animals

It is mostly weight and pressure packing the soil too dense, and then getting tilled to expose it to air. The soil loses nutrients and the ability to hold moisture and organisms like worms, bugs and bacteria. The article describes these iss

Well we did shovel a big cart full of manure to the field, that sure did help. But the horses pooping during the work is pretty negligible in comparison.

I recently took part in a course on doing farm work with horses. It was a large garden where all the farm work had been done exclusively with horses for about 10 years, after decades of using tractors. The tractors had turned the soil into

Yeah, sure that kinda works but it won't play nice with having an event loop on network events. A typical high performance server has multiple worker threads waiting on events on a select/epoll and if you add in another thread (or

You can't do that with normal read/write and select/poll/epoll, but you can either use aio (posix) or io_submit (linux-specific). In my opinion, a big issue with these is that asynchronous i/o requests can not be us

That's obviously a good use case and doesn't even need to have that large of number of elements because the data could get consumed by the GPU, so no back-and-forth transfer necessary. This paper was focused on comparison based so
