Huh I'm surprised even that happened. Around ten years ago I found a half dozen for-profit "security" products that were using WireShark unattributed and reported it to the Wireshark team. I lost track of them after a few years but nothing changed despite a strongly worded "Thanks we're going after these guys hard" email from WireShark. And that's GPL not MIT.

You are developing a Windows application for syncing user photos between a PC and your cloud service. Where would you store a local cache of files?

A) In the user profile folder, Local AppData or similar
B) In the shared user profile, C:\ProgramData or similar

null terminated strings were a mistake and any use of any c stdlib str* functions is a code smell. please use one of the many libraries that provide sane strings implemented using structs that store the length and capacity alongside the buffer.

Ehh, like anything else it is safe if you know what you�re doing and are in a controlled context.

But I guess from that perspective so are while loops looking for null terminators...

Foxfire_: Nov 8, 2010

"ASCII text over serial" is a fairly common protocol for talking to equipment from embedded stuff that adds string handling to things.

I like to do strings as unterminated fixed size arrays in structs i.e.

code:

struct ThingCmd
{
    char Text[THING_CMD_SIZE];
};

You can copy them with =, sizeof() them, static analyzers are better about noticing if you overrun them, and they tend to explode dramatically if someone isn't paying enough attention and tries to use str* functions on them.

I dunno if this is a "horror", per se, but it's a completely ridiculous thing I learned at a recent talk at work.

Apparently, CPython doesn't have any concept of primitive types - everything is spun up into a struct with a bunch of ancillary type information. Naturally, creating and maintaining structs is more expensive than just putting a value in a memory location. At some point, someone said "I bet we could improve performance if only there was some way to reduce the amount of cycles we spend creating and garbage-collecting all these structs for frequently used values." I believe this person then proceeded to drink heavily while thinking about the problem, because at some point on the far side of the ballmer peak they decided that the best course of action in this instance would be to preconstruct a set of "small number" objects and return references to those any time an object with that value was needed rather than creating a new object. Our talk didn't cover the exact range (it may vary depending on system?), but the tl;dr is:

code:

> val hundred = 100
> val thousand = 1000
> hundred is 100
true
> thousand is 1000
false

This apparently applies to "small strings" as well, e.g. aaaa, bbbb, ...

Whatever makes python faster, I guess?

e: thousand != 100

this kind of thing is commoner than you might think. e.g. java does the same thing for instances of the Integer class with small values. and the optimisations some languages do to reduce memory usage of short strings are quite impressive.

i'm surprised python bothers though given how little thought they normally give to performance

Plorkyeran: Mar 22, 2007; To Escape The Shackles Of The Old Forums, We Must Reject The Tribal Negativity He Endorsed

CPython refuses to do big structural changes for the sake of perf, but that's a pretty easy localized optimization that doesn't really impact the rest of the code base and has big benefits.

# ? Nov 29, 2018 19:08

EssOEss: Oct 23, 2006; 128-bit approved

I assume that is supposed to say "thousand = 1000" but yeah, this is very common and just a thing you do if you want performance. For example, the .NET async/await system works by wrapping all sorts of results in a Task structure, which is a real waste if the task is short-lived or, even worse, executed synchronously so it just goes to waste right from the start. So it keeps a cache of things like "task that returned with true". Things have improved in the next version, though, where you can skip some of these allocations altogether.

It's the difference between "same value" and "same object" so it was intentional.

Not the last line, the one that initializes "thousand" needs to be fixed for the demonstration to work.

code:

>>> hundred = 100; thousand = 1000
>>> hundred is 100, thousand is 1000
(True, False)

# ? Nov 29, 2018 20:42

Dylan16807: May 12, 2010

Oh and for bonus points if you put that in a file (or compress it to one line) you get a different result, because all instances of "1000" compiled at the same time will share the same object.

As someone already said, Java does this too. What is extremely fun is that IIRC you can use reflection to gently caress around with the conversion slots, so that int with value 2 converts to Integer that has value 4... :v:

I mean if you do it, it is your own drat fault, but it is still pretty drat funny.
