As others said, you can't really do it without disassembling the function (bonus problem: the general case is undecidable). A solution is to have your linker insert a "end of function" symbol in the ELF object (using a linker

That's quite surprising, it's a textbook XSS vulnerability. It seems to me that their markdown library should escape entities by default or they will have many other vulns.

pickle is a (de-)serialization library for Python. It allows arbitrary code evaluation, so shouldn't be exposed to the outside world (for the same reason that we have JSON parsers and don't use JS eval() to parse JSON).

Σ(2^i / (10^(5i)) = Σ(2/10^5)^i = 1/(1-(2/10^5)) = 10000/9998 (you get the idea)

It's not calling the git command that's problematic, it's calling an external command at all. So you pretty much have to recode the hot part in another language, where you just manipulate buffers instead of piping stuff aroun

Can you make it available somewhere? I'd be interested in that data, and sure that others would be too. Thanks!

The difference is in the error message you get. Adding "if (x == NULL) abort()" will display a backtrace near the error. To understand the cause of the segfault, you will have to follow the data flow in your favorite debugger.

The big problem for me is the compilation time, which is very slow (this may or may not be because the compiler itself is written in Rust). I dedicated a few days to hacking on rustc this summer, and while the tooling and community are very

Undefined behaviour is a dynamic property, not language constructs. It's akin to saying "remove run-time errors from your programs".

I think that the commit history says a lot about the development process and the company culture. First, is that it's interesting to see how these companies work internally. Second, it's easier to dive into the code by reading the

I understand that it's not worth the cost to cleanup the history, but it's always frustrating to see such a project come with a 100kloc "initial" commit.

Snapchat works like this and is reasonably successful. But of course, there is no technical way to enforce the ephemeral aspect.

When microwaving a CD, the induction stops when the track is cut. There are usually big chunks of surface (~2cm²) unaffected. You can't read it with your drive but it's reasonable to think that some data can be retrieved from it,

Interestingly enough, the switches are not electric ones. It's just something that can be physically (maybe even optically) detected by the device.

X32 code is different from "plain" 32 bit code (x86 style) as it still runs in long mode and can use all registers.

Make only understands rules such as "X depends on Y", but gcc can output these dependency rules (-M* switches). So yes, it is possible to do this but make itself is source code agnostic.

There are very few releases of GNU make: 3.81 (in Debian too) is from 2006, 3.82 from 2010 and 4.0 from 2013.

That was between S12 and W13: http://ycombinator.com/w13smaller.html I can't find the source for the cut in extra VC funding but it was around the same time.

The difference is that Haskell does not check types at runtime like Clojure does (which is the point of strong static typing), so if the type is wrong it becomes as unsafe as C.
