It's not widely known, and it seems to be still in the research stage. A lot of things in this area never really get out of that. It did not happen for MPX. Many distributions build binaries for SHSTK, but I doubt anyone is enabling it

This is helpful as well because it at least alludes to the data structures: https://github.com/pizlonator/llvm-project-deluge/blob/delug... One more thing: I assume the memory allocator has a somewhat efficie

ISO 8601 covers that. Weeks start on Mondays. The first week of the year has January 4th in it, which means that it sometimes starts on a Monday in the previous Gregorian year. This is why strftime has separate format specifiers for ISO yea

You may find it funny, but it's unclear if profile-guided optimization is permitted under typical corporate AI policies.

I wouldn't say that. In the German media, family-owned businesses tend to be treated as Mittelstand regardless of size, and their owners' statements are sometimes portrayed as reflecting general “Mittelstand“ concerns even if the

Bosch is a bit of an outlier due to its structure and age. But there are definitions that would include Meta as Mittelstand, like this one: https://www.ifm-bonn.org/en/definitions/mittelstand-definiti...

You can try the digital toolkit and see for yourself if this is a realistic pathway for a small site (such as a blog with a comment function). Personally, I find it puzzling that Ofcom thinks what they provide is helpful to small sites. Fur

Isn't core financial literacy a bit more basic than that? Like how to pay your bills? I wasn't taught any of these practicalities in school, and it I suppose it could have been useful.

And this is covered by building codes (and labor codes in case of commercial use).

If I recall correctly, earlier versions of iText lived on in Linux distributions as part of pdftk, until that became unbuildable because it had a hard dependency on GCJ: the command-line parser was written in C++ for some reason. Most previ

Even more confusing is that the AGPL explicitly deals with this scenario: “ If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction,

As far as I know, there is no tooling support to propagate these marks to the launcher program even in cases where they can be statically discovered. (This could be similar how dynamic linker agents (audit modules) are handled by the Solari

How does Go avoid getting bogged down by middleware-oriented programing in practice? I think most large-scale programming in organizations tend to converge on that because it sort of works. Is it that people who like this kind of stuff writ

Is MADV_FREE memory charged? It contributes to classic RSS, but can be discarded by the kernel if it deems that beneficial.

Linux has had unprivileged chroot for a while, via user namespaces. Their setup is a bit complicated if you want to support nesting in other container runtimes: https://sourceware.org/git/?p=glibc.git;a=blob;f=support&#

Is the amdgcn GCC backend any better? (Or maybe final register allocation is not performed before llvm-mc is called—GCC reuses llvm-mc due to lack of binutils support.)

There is the idea floating around to do this for the main thread (especially for audit mode, where the automatic static TLS size discovery does not work due to the way the audit interfaces are defined, it's not merely an implementation

I was curious because over here, the ownership of signal.me is pretty much obscured (behind Cloudflare and WHOIS privacy). Doing this for infrastructure domains is not a good idea because it encourages persistent overblocking because it mak

GCC uses a region-based allocator with graph coloring, based to some extent on Callahan/Koblenz's work I think: https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/ira.cc Note that in the GCC context, LRA me

It depends on the amount of TLS and the number of objects that do this, and the C library. In glibc, we have a small static TLS reservation dedicated for use by dlopen of shared objects with initial-exec.

by fweimer 2y ago
With glibc, you can use -ftls-model=initial-exec (or the corresponding variable attribute) to get offset-based TLS. The offset is variable per program (unlike local-exec), but the same for all threads, so it's more efficient. Using too

Is it really a technical capacity issue, or just market segmentation? Usually, it's possible to get so-called business service with higher upload bandwidth, even at residential addresses.

Most development in this space (toolchain and kernel) is funded in some way. I don't know if this particular project is at some strange intersection where this isn't the case, but I would be surprised. Writing policies hard, and t

What do you mean? Do you want to annotate the condition as unpredictable, so that the compiler always assumes that a conditional move is beneficial? (Compilers obviously do this transformation, including GCC, but it is not always beneficial

More often, people create a spreadsheet with one row per bug once they encounter situations like that. It's a tool failure because these activities are of course core bug tracking tasks, yet bug tracking tools tend to be a poor fit for
