Regular expressions as we basically now them today were made for ed. In that context, '$' absolutely had to match the terminating newline or it would've been completely useless.

Well, if you're fine with using 3-year old versions of those libraries packaged by severely overworked maintainers who at one point seriously considered blindly converting everything into Flatpaks and shipping those simply because th

Like, seriously. It's impossible to run Erlang/OTP 21.0 on a modern Ubuntu/Debian because of libssl/glibc shenanigans so your best bet is to take a container with the userspace of Ubuntu 16 (which somehow works just fine

No you can't. If a user can read something, it can execute it. The only thing where it matters is setuid applications where the setuid bit allows the user to run an application as someone else . But it's already a separate permis

Honestly, sometimes I just want to mark all files on a Linux system as executable and see what would even break and why. Seriously, why is there a whole bit for something that's essentially an 'read permission, but you can also di

It's small, but not unnoticeable... depending on the exact size of the workload and the amount of computation per element. In fact, for huge arrays it may be beneficial to have structs packed if that leads to less memory traffic. [0]

Do I understand it correctly that the logic is that if timestamp B is above timestamp A, but the difference is more than half of the unsigned range, B is considered to happen before A?

They've meant something like "arbitrary", in its "without any good/justifiable reason" sense. The word "random" is also used in this sense, especially when talking about human-made decisions.

Every time I see yet another dotfile-management solution I just can't help but wonder: maybe it's the dotfiles that are the problem?

Well, we didn't, for obvious reasons, patch JVM to manually finagle with physical memory allocation — which it probably wouldn't be able to do anyway, being run in a container.

From what I can see in the codegen, defer is not implemented "properly": the deferred statements are only executed when the block exits normally; leaving the block via "return", "break", "continue" (i

Some architectures had CALL that was just "STR [SP], IP" without anything else, and it was up to the called procedure to adjust the stack pointer further to allocate for its local variables and the return slot for further calls.

There is also a problem of nested virtualization. If the VM has its own "imaginary" page tables on top of the hypervisor's page tables, then the number of actual physical memory reads goes from 4–6 to 16–36.

I mean, if the stacks grew upwards, that alone would nip 90% of buffer overflow attacks in the bud. Moving the return address from the activation frame into a separate stack would help as well, but I understand that having an activation fra
