The New Stack covers a conference talk by Bjarne Stroustrup on turning C++ into a safer language. Stroustrup has arrived at his solution: profiles. (That is, a set of rules which, when followed, achieve specific safety guarantees.) They’d be defined by the ISO C++...
The 6.6 kernel was released, right on schedule, on October 29. This development cycle saw the addition of 14,069 non-merge changesets from 1,978 developers — fairly typical numbers for recent releases. The time has come for LWN's traditional look at where the changes in...

Linus has released the 6.6 kernel. 'So this last week has been pretty calm, and I have absolutely no excuses to delay the v6.6 release any more, so here it is.' Headline features in 6.6 include the earliest eligible virtual deadline first (EEVDF) CPU scheduler, a number of...

User-space developers working with highly threaded applications would often like to be able to use spinlocks to protect shared data structures from concurrent access. There is a fundamental problem with user-space spinlocks, though: there is no way to prevent a thread from...
For a view into the OpenBSD approach to security, see this message from Theo de Raadt, where he describes a plan to remove the syscall() system call (which allows the invocation of any available system call by providing its number) from the kernel. The purpose, of course, is ...

The C programming language is replete with features that seemed like a good idea at the time (and perhaps even were good ideas then) that have not aged well. Most would likely agree that string handling, and the use of NUL-terminated strings, is one of those. Kernel...
Security updates have been issued by Debian (firefox-esr and xorg-server), Fedora (firefox, mbedtls, nodejs18, nodejs20, and xen), Gentoo (libinput, unifi, and USBView), Mageia (python-nltk), Oracle (linux-firmware), Red Hat (nginx:1.22), SUSE (chromium, firefox,...

The kernel has, for many years, had the ability to control how memory allocation is performed in systems with multiple NUMA nodes. More recently, NUMA nodes have also been pressed into service to represent different classes of memory; those nodes are now organized into tiers ...
The Python Steering Council has posted a detailed plan for the addition of 'free-threaded' (no global interpreter lock) support into the Python mainline. It will not be a short process and does not have a guaranteed successful outcome. Phase I: Experimental phase, which...

Many home-automation devices come with their own mobile app or cloud service. However, using multiple apps or services is inconvenient, so it's (purposely) tempting to only buy devices from the same vendor, but this can lead to lock-in. One project that lets users manage...
Version 119.0 of the Firefox browser has been released. The list of changes includes improvements to Firefox View, some PDF-editing improvements, better cookie protection, encrypted client hello support, and more.

The 2023 election for members of the Linux Foundation Technical Advisory Board will be held during the upcoming Linux Plumbers Conference. The call for nominees has been posted. The TAB exists to provide advice from the kernel community to the Linux Foundation; it also...

It is probably fair to say that most Linux users spend little time thinking about the troff typesetting program, despite that application's groundbreaking role in computing history. Troff (along with nroff) is still with us, though, even if they are called groff these days,...
