Using ""restrictive" because they remove the right to add restrictions" is like thinking the law is restrictive when it removes my freedom to kill people. You can use that word with that meaning, but then I won't se

It would be unwelcome for BSD projects to complain about freeloaders given "freeloading" is explicitly authorized. You can take a quick look at https://en.wikipedia.org/wiki/List_of_products_based_on_Free...

The problem kind of exist but the comparison is mostly bullshit -- or at least was until recently. Windows regularly breaks driver compat, even more so on Windows phone. Only with Windows 10 Mobile they engineered a strong way to upgrade th

It depends, with perfect components maybe as rare as one bitflip a year, or maybe even less. However you can have all the spectrum with slightly defective components. There are some rates that are really unfortunate because you don't e

That's bullshit. You have no reason to care about data integrity in your NAS but not in your workstation. Plus "random" bitflips can have various causes, and except if you spend a weekend to a month memtesting your non-ECC ra

Uncorrected memory exception are handled by the OS (at least on sane OSes?). I don't know why the author think otherwise.

The conclusion of the article is mostly false at least for Linux: UE errors have no reasons to panic the machine in all cases, and by default under Linux the affected processes are simply killed. Of course, if this is kernel memory, then yo

Well, falsification of certificates seems to be quite common by nuclear subcontractors, and depending of the number of alternative shops able to do (kind of) the same thing (minus or plus correct quality...) those who falsify stuff might ge

What do you mean by checking against double-free? Either you pay a high runtime cost, or use unconventional (and somehow impractical in C++) means (e.g. fancy pointers everywhere with a serial number in them), or you can't check reliab

Of course it is a C issue, in the same sense that ALL logic errors are in the case you describe -- so either C issues do not exist or you did not manage to find the correct definition: for ex OOB access is caused by faulty program logic, an

Or maybe 3x9 if you are doing wild random accesses in big area, or even worse in huge area if your TLB and then caches start to not hold enough and you effectively need to do multiple accesses for each single ones, but you are right: DRAM i

I'm still unsure of the rate at which this could be a solution to leverage checked C++ library types, and whether in the precise case of the Cloudfare issue this would be applicable. However I still think that in most case if you must

C++ would not have helped as a target language for compiling Ragel, at the level the compiling is done. Actually IIRC Ragel enhanced their output to mitigate that kind of situation, and the intermediate language they target is still C. I&#x

There seems to be some people in the IDE team who believe that a 32-bits only IDE is a feature and not a bug, including for reasons as fun as because it crashes sooner in case of memory leaks... I guess eventually those people will move to

I never get why some people think the Win32 MSDN doc are appropriate. They are typically several order of magnitude less precise than man-pages on function about a similar topic -- if not just containing a few errors!

If grepping and piping is not productive for you, you are simply doing tasks that do not require that to be productive. OTOH working on some non-trivial code bases, maybe including system level code, typically requires grepping and piping,
