The 5ms isn't the key number. It's 5ms extra over a 28ms baseline, that's about 18% difference. If your noise threshold is 18%, then I think you have to accept that the benchmark probably isn't any good for this stated t

Is it even possible to do push notifications without relying on a centralized system (Google, Apple, or whoever)? Sounds like a very difficult problem to solve while preventing privacy leaks, spamming, DOS attacks and still being reliable a

A compiler bug is a compiler bug, UB or not. You might as well just say "There have been more than a few compiler bugs, leading to very incorrect program behavior."

So bad driving causes crashes? Who would that thought? It's not that the faster car is safer then, it's just the fact that if you try to overtake without sufficient room, you will be taking a risk. No-one is disputing that a faste

I'm not sure that's right. The compiler isn't tracking undefined behaviour, it is tracking possible values. It just happens that one specific input into determining these values is the fact "a valid program can't de

The compiler didn't find UB. What it saw was a pointer dereference, followed by some code later on that checked if the pointer was null. Various optimisation phases in compilers try to establish the possible values (or ranges) of var

Why is it safer? Are you saying that you would otherwise overtake another car in an unsafe way, perhaps when you haven't enough visibility to check if there is no oncoming traffic for the overtake time? That's on you. The decision

That's a good point - I reckon Mercedes haven't thought this through fully yet. All cars have their branding and model number on display, perhaps what new cars will have is some kind of fancy electronic display on the back that sh

I think that the author is saying that it is very difficult not to disclose that a user exists, and so there is not much point obfuscating it. Validating an email address on signup is only one way to 'leak' usernames. If you can o

True, but the story covers that aspect - many systems provide other ways to check if a username exists (e.g. trying to register a new account, or sending an email to a gmail address, and so on)

But the error message can be true. If you mistype your username, you might have entered another, existing username. Just telling the user 'wrong password' will mean they are less likely to check that the username was correct. Th

Yes, I read that man page. It states: EOVERFLOW: pathname or fd refers to a file whose size, inode number, or number of blocks cannot be represented in, respectively, the types off_t, ino_t, or blkcnt_t. This error can occur when, for

by joosters 4y ago
Sure, but EOVERFLOW isn't coming from stat() in this case, is it? The man page states that this is returned for problems with file sizes too big for 32 bits, not for struct timespecs. Something else must be doing things with the atim

It seems odd that the problem is in the access time of the files - why does a font library (or, almost any program) care about the last read time of a file? Sure, the modification time is important, but it's pretty rare that code s

It's just like any kind of snobbery. If you want to be a connoisseur, it's practically obligatory to detest all the popular options. Because you (i.e. this website) are the expert and the commoners must be tasteless and wrong!
