The idiot who committed AWS keys could have omitted VS from the post title, but then people would just call him a loving idiot for committing AWS keys. Because he is.

I use the poo poo out of parens in some of my kernel code. Partially because it helps make casts and such look saner, and partially because it seems to turn dummy mode on in some programmers and they just assume I'm a loving wizard.

Travis-CI looks really cool, and I want to try getting it to work with my project, but I'm a bit unsure about getting it to cooperate by building not one but two complete GCC cross-toolchains as a dependency. Especially after reading about that horror.

It's nice to be able to instantiate a new object of a class for a certain piece of hardware if there happen to be multiple of that hardware in the system. Find two RTL8169s on the PCI bus? Spin up two NetRealtek8169s or whatever. Of course, you can approximate that with structs and function pointers in C if you're working in C, but C++ throws in poo poo like inheritance, which would be useful for similar chips that have slightly different register layouts and all that.

The C standard pisses me off because in 2015 with the latest standard in use, it is still perfectly legal for sizeof(int) to be 2 bytes. That is some serious early 70s poo poo and I do not appreciate it. There are many stupid little gotchas in the standard like this. This is just the tip of the iceberg.

How the gently caress, other than seeing it enough to know what it means or googling it, is anyone who doesn't know Hebrew supposed to know that it means "double colon"?

Here's some coding horror in the prosumer products world: http://appleinsider.com/articles/16/02/12/bug-in-adobe-creative-cloud-updater-erases-root-level-mac-data Adobe pushes an update for Creative Cloud on Macs that makes the assumption that they're going to be the first folder in the root directory and that whatever comes first is okay to wipe out. Some users don't have that folder and the first one in the list for them is .DocumentRevisions-V100, which is the OS X equivalent of the volume shadow copy store on Windows.

Subjunctive posted:I've worked on projects with subcomponents named "libpr0n" and "GraphicsEx", and I don't think anyone ever actually submitted a diff to change them (though diffs renaming directories weren't really a thing then I guess). I am reminded of the Markdown rendering library libsoldout, which was changed from libupskirt after the person behind it was bombarded with so much hate she said she would have rather not written the library in the first place. The developer was not a native english speaker and was basically forced out of open source development by the kerfuffle.

Before Seventh Edition, crypt() wasn't even DES. It was introduced in Third Edition as a software implementation of the WWII M-209 cipher machine, using the user's password as both the key and the message to encrypt with the cipher. That was good enough for a project pretty much internal to Bell Labs and used almost entirely for word processing in the early 70s. In Seventh Edition they changed it to 25 rounds of DES on a block of zeros because guessing M-209 results became too fast to be secure by 1978/1979. Technology marches on.

Internet Janitor posted:I've always assumed that C went with null-terminated strings because it lets you do in-place tokenization tricks and passing a pointer midway into a string without needing to reallocate anything makes writing recursive descent parsers very simple. They picked the representation that makes it easy to write a self-hosting compiler, and every other application paid the price. Yeah, a lot of design tricks were needed to bootstrap a self-hosting compiler for a portable language and an OS written in it on a machine that generally shipped with 24 kilobytes of RAM.

You want to deal with a filename nightmare? Pulling files with astral plane characters in them off a FreeBSD ZFS box via tar -> scp -> untar onto a Windows machine is the worst loving thing I've done regarding filename encoding. You'd think because it should be some kind of Unicode on both ends, it'd work well, but no. Somehow the multibyte encodings got mangled into codepage 437, the characters of which Windows promptly directly translated to what I *think* was UCS-2, but I'm not sure (eg. the UTF-8 sequence byte 0xB6 was interpreted as CP437, and became U+2562). There are probably a number of things that Windows will happily munge in this way.

It's weird old DOS/Windows code page crap that stuck around in the Unicode era. Part of the reason from my understanding for the weirdness is because the backslash didn't exist before the ASCII standard was developed, and its origin was for writing out full-height logical AND and logical OR operators for ALGOL. More fun: forward slash has been a valid path separator since paths were introduced to DOS in 2.0. All the developers were UNIX guys, but backslashes were used as the default at IBM's insistence because CP/M and the CP/M-like tools used forward slashes for switches. You could pass paths with forward slashes to the DOS API and it'd be totally fine with it, but COMMAND.COM and the CP/M-like environment used forward slashes for switches and backslashes for path separators because everything had to feel like CP/M. The UX developers for DOS 2.0 then snuck in a system call and a corresponding CONFIG.SYS flag called SWITCHAR that let you set the switch character used by the option parsing API to a dash instead of a slash.
