Needing two tokens of lookahead is fairly common. For example, in Lua "local IDENTIFIER" is a local variable declaration and "local function" is a private function declaration.

I'd add that in the Brazilian these medical schools frequented by the children of the elite, graduation party funds add up to hundreds of thousands of dollars. Students are expected to pony up a sizeable monthly sum starting from the f

The downfall is that in theory the purpose of school is to educate, not merely get people enough points to be admitted to college.

This is more about responsiveness than batch-processing speed.

This beligerance towards the supreme court and in particukar MR. Moraes is old news. For the most part, it comes from the radical right. Currently they are antsy because the supreme court is working towards prosecuting the people behind the

IIRC, the perf regression only happened if the code was compiled with -fno-omit-frame-pointer, which was not the default. https://mastodon.social/@AndresFreundTec/112187000944648334

IIRC, according to Andres Freund the perf regression only happened in machines using the -fno-omit-frame-pointer setting, which was not the default at that point.

Chaining login methods would not help if the outermost login method is backdoored with an RCE.

I've heard that it was only detected because the developer that found it was using different compiler flags than the default. Under default settings, the backdoor was stealthier.

We were lucky that the backdoor called attention to itself, because it impacted the performance off ssh and introduced valgrind warnings.

I don't know all the holidays but they have commits on Yom Kippur dates in 2021 and 2022. For 2023 it's harder to say because their commit activity is sparser.

The malicious developer did not add bugs to xz, they used xz as an attack vector. They added malicious shell code to the xz build scripts, so that when you build and install xz it attempts to inject a backdoor into sshd. The malicious shell

In there any actual meaning behind the Political Compass they're referencing? I only see it in those memes that left me with the lasting impression that the whole thing is bullshit.

The devil is in the details. For example, Make decides to rebuild based on timestamp, while Bazel decides to recompute based of file hashes. Thus, if you touch a file but don't change its contents, Make might rebuild things that Bazel

In a build system, when you update a source code file, it should recompile the binaries that depend on it. Similarly, in excel when you update a cell in the spreadsheet, it should recompute the cells that refer to it. The paper is about thi

Would a lower complexity be enough, with proper key stretching?

The purpose of parenthesis is too let the language know when the condition ends, and the statement begins. In a language with mandatory curly braces, the brace does that job already.

I find the statements about best efforts hard to believe, considering that we're talking about the most far-right government Israel ever had, with several cabinet members making statements in favor of removing all Palestinians from the

Typically you'd have some assembly functions in a separate file. Compile to an object file and link it, as you'd do with a separate C file. If you want to insert assembly snippets inside a C function, many C compilers have an inli

That's just for convenience though. Users can edit their own PATH as they see fit.

In all the distros I know, bin and sbin have the same permissions.

That way users can get all the package-manager goodness for stuff they compiled locally. And also because Gobolinux lets people install more than one version of the same package.

Actually predates NixOS, by a couple of months.

Sorry, I'm not sure if I get your point. Separating /usr and /usr/local doesn't have to do with permissions; it's just that package manager wouldn't be able to deal with users installing files into /u

Is that only for command substitution?

If the shell were to treat cat as a builtin, could it implement cat| as a stdin redirect? I wish I could write "useless cat" without people pestering me about it.
