All underutilized systems are essentially the same, but each overutilized system tends to be overloaded in its own way. If one's goal is to maximize the use of the available computing resources, overutilization tends not to be too far away, but when it happens, it can be...

Python creator and Benevolent Dictator for Life Guido van Rossum has decided, in the wake of the difficult PEP 572 discussion, to step down from his leadership of the project. 'Now that PEP 572 is done, I don't ever want to have to fight so hard for a PEP and find that so...
Mounting filesystems is a complicated business. The kernel supports a wide variety of filesystem types, and each has its own, often extensive set of options. As a result, the mount() system call is complex, and the list of mount options is a rather long read. But even with...

The compromise of the Gentoo's GitHub mirror was certainly embarrassing, but its overall impact on Gentoo users was likely fairly limited. Gentoo and GitHub responded quickly and forcefully to the breach, which greatly limited the damage that could be done; the fact that it...

<p> A recent query about the status of network security (TLS settings in particular) in Emacs led to a long thread in the emacs-devel mailing list. That thread touched on a number of different areas, including using OpenSSL (or other TLS libraries) rather than GnuTLS, what...

Here's a report in Sensors Tech Forum on the discovery of a set of hostile packages in the Arch Linux AUR repository system. AUR contains user-contributed packages, of course; it's not a part of the Arch distribution itself. 'The security investigation shows that shows that...

In many ways, Spectre variant 1 (the bounds-check bypass vulnerability) is the ugliest of the Meltdown/Spectre set, despite being relatively difficult to exploit. Any given code base could be filled with V1 problems, but they are difficult to find and defend against. Static...

In the 4.18 kernel, a new feature was merged to allow infrared (IR) decoding to be done using BPF. Infrared remotes use many different encodings; if a decoder were to be written for each, we would end up with hundreds of decoders in the kernel. So, currently, the kernel only ...

The 4.18-rc4 kernel prepatch has been released. 'Things look pretty normal here, and size-wise this looks good too, so it's another of those 'solid progress to release' weeks. Boring is good.'
For those with a significant chunk of spare time and nothing better to do: Swapnil Bhartiya interviewed LWN editor Jonathan Corbet in February has now posted the resulting video on the Patreon site.
