Tells you exactly what and at which line the problem is?

Syntax error: unmatched thing in thing from std::nonstd::__map<_Cyrillic, _$$$dollars>const basic_string<epic_mystery,mongoose_traits<char>, __default_alloc_<casual_Fridays = maybe>>

Sure, strtok is a terrible misfeature, a relic of ancient times, but it's plainly the heritage of C, not C++ (just like e.g. strcpy). The C++ problems are things like braced initialization list having different meaning depending on the set of available constructors, or the significantly non-zero cost of various abstractions, caused by strange backward-compatible limitations of the standard/ABI definitions, or the distinctness of vector<bool> etc.

Int3 is a special single-byte (CC, if I recall correctly) form of the INT instruction (which is CD imm8, I think) to raise an interrupt. Interrupt #3 is the debugging interrupt, so by overwriting any instruction with CC, you place a breakpoint there.

Beware the DWIM!

In one notorious incident, Warren added a DWIM feature to the command interpreter used at Xerox PARC. One day another hacker there typed delete *$ to free up some disk space. (The editor there named backup files by appending $ to the original file name, so he was trying to delete any backup files left over from old editing sessions.) It happened that there weren't any editor backup files, so DWIM helpfully reported *$ not found, assuming you meant 'delete *'. It then started to delete all the files on the disk!

It's not as easy as it sounds, sometimes the screens are all wrong!! https://xkcd.com/722/

When you're saying Unix time does not include leap seconds, you are making exactly the wrong conclusion. Unix time is not a monotonically increasing number of seconds since the Epoch, because it excludes those seconds which are marked as leap seconds in UTC. I.e. the time between now and the Epoch was larger than the current Unix time shows (by exactly the number of leap seconds in between). See e.g. https://en.wikipedia.org/wiki/Unix_time#Leap_seconds

Well... unless you measure the number of [milli]seconds using something like time_t, which lies because of leap seconds. I.e. even such a seemingly simple interface, in fact, includes a calendar.

That's against the terms of math :-)

It will not "overflow". Signed integer overflow is undefined behavior. The compiler could remove the whole loop or do anything else imaginable (or not).

Oh, and you can do that even in the official application? I thought it was impossible to be logged into multiple Teams accounts at the same time! (That was one of the reasons I was using Teas in a browser, being able to open another instance in a private window.) Or did they finally fix that, at least?

 

After choosing what I wanted to do in the first step of the developer satisfaction survey, I have to check that I did complete the task successfully (presumably thanks to their great support website), otherwise, I cannot continue, “This question requires an answer”.
