Indeed, it can happen too. All software is different, bugs are different, and optimal debugging tactics is very different as well. But when the one in my comment does work, the saved debugging time can be measured in days . Speaking about

Yeah, but I’m pretty sure DNS over HTTPS will become default in a couple of years. I don’t believe the government should spend taxpayer’s money fighting a problem which will soon disappear automatically, regardless of their [in]actions.

Over the last few years, most of the internet upgraded to TLS. This technological shift made it much harder, and in many cases borderline impossible, for ISPs to mess with the traffic.

I think that behavior is totally fine, but only if the change is communicated to the people using the program or library. I had an interesting issue with Nuget package manager. Authors of some open-source package we’re using changed their l

fork() is rarely ideal, unless followed by exec() to launch another processes. That copy-on-write thing often wastes too much physical memory. I think threads are usually better, the shared memory allows to marshal large volumes of data wit

I think it’s the language. Haven’t really tested but in C# that would be something like that, 8 lines of code instead of 40: public static byte[] func( uint p, uint q ) { int pw = 32 - BitOperations.LeadingZeroCount( p );

I think if you watch that 4k video with nearest neighbor downsampling (i.e. the player which drops 75% of pixels and only render 25% of them, one from each 2x2 quad), you’ll get worse quality. Fortunately, that’s not how video players norma

I agree with GP. When I started my career in 2000, people used C or C++ for pretty much everything. People wrote desktop GUI apps with MFC. People built web apps with cgi-bin, ISAPI, and C++ implemented COM objects consumed from asp classic
