Ars Technica reviews the Purism Librem 5 smartphone, which is made from open-source software and (mostly) open hardware. It is clearly not there yet as a replacement for the phone in our pockets, but it would seem to be on the right path. "The thing to keep in mind here is that Purism has […]

The Electronic Frontier Foundation (EFF) has put out a statement in support of journalist Glenn Greenwald whose "prosecution is an attempt to use computer crime law to silence an investigative reporter who exposed deep-seated government corruption". Greenwald is being charged in Brazil, where he […]

One year ago, the io_uring subsystem did not exist in the mainline kernel; it showed up in the 5.1 release in May 2019. At its core, io_uring is a mechanism for performing asynchronous I/O, but it has been steadily growing beyond that use case and adding new capabilities. Herein we catch up with […]

Some years back, I was caught in a weak moment and somehow became the kernel documentation maintainer. More recently, I've given a few talks on the state of kernel documentation and the sort of work that needs to be done to make things better. A key part of getting that work done is communicating […]

Keith Packard is no stranger to the linux.conf.au stage; he has spoken on a wide variety of topics since he started going to the conference in 2004 (which was held in Adelaide, where organizers apparently had a lot of ice cream for attendees). One of his talks at this year's conference was on an […]

Control-flow integrity (CFI) is a technique used to reduce the ability to redirect the execution of a program's code in attacker-specified ways. The Clang compiler has some features that can assist in maintaining control-flow integrity, which have been applied to the Android kernel. Kees Cook […]

Wine 5.0 has been released. The main highlights are builtin modules in PE format, multi-monitor support, XAudio2 reimplementation, and Vulkan 1.1 support. Wine is capable of running Windows applications on Linux and other POSIX-compliant systems.

Brent Roose argues that it is time to take another look at PHP. "In this post, I want to look at this bright side of PHP development. I want to show you that, despite its many shortcomings, PHP is a worthwhile language to learn. I want you to know that the PHP 5 era is coming to an end. That, if […]

Once upon a time, there were few ways for one process to operate upon another after its creation; sending signals and ptrace() were about it. In recent years, interest in providing ways for processes to control others has been on the increase, and the kernel's process-management API has been […]
