[$] Ways to encrypt data on servers
At the 2026 edition of FOSSY, RomeoSolano gave a fast-paced, humorous presentation on what could have been arather boring topic: server encryption. There are a number of threats thatwe face in today's world, from criminals, government overreach, espionage,and more, that can be thwarted with encryption. But encrypting data on asystem that may live elsewhere, without any access to its keyboard at boottime, is rather more difficult than encrypting the disk of a laptop.Solano described the problems and gave a tour of some of the solutions inthe talk.

[$] Adding BPF to blk-iocost
The scheduling of block I/O requests has longbeen a challenge for operating-system kernels. For many years, theperformance characteristics of rotating drives meant that puttingconsiderable resources into request ordering was worthwhile. In a worldwith fast, solid-state drives, scheduling is more concerned with enforcingfairness between competing users while being fast enough to keep up withdrives that can perform millions of I/Ooperations per second. The blk-iocost I/Ocontroller was designed for the solid-state world and generally performswell, but there is always a desire to do better. This patchseries from Tao Cui aims to make blk-iocost more flexible by enablingthe loading of a BPF program to make cost decisions.

[$] Accelerating the kernel's build process
Kernel developers do a lot of kernel builds. Since the kernel is not asmall program, those builds can take a fair amount of time, even on a fastmachine. The kernel also has a complex build system; it is probably fairto say that few developers truly understand it, and fewer still are willingto try to improve it. Lorenzo Stoakes, armed with LLM-based assistance,decided to give it a try, though, and has managed to reduce the time ittakes to build a kernel - and not by a small amount.
Two stable kernel updates for Friday
Greg Kroah-Hartman has announced the release of the 7.2.5 and 6.18.51stable kernels. There are more than 550 patches in each with fixes throughoutthe tree; users are advised to upgrade.

[$] PostgreSQL 19's "scary patch contest"
PostgreSQL 19 was expected to be released in September, in keeping with the databaseproject's longstanding tradition of a major release every year. However,some late-breaking concerns about several of the features slated for inclusionhas some developers worried about the quality of the release. On August 25, PostgreSQLcontributor Robert Haas sentan email with the subject "scary patch contest" about several patchesthat have required an unusually large number of bug fixes leading up to therelease, which has raised questions about their readiness for a stablerelease. One of the patches has been reverted, but several are still under heavyrevision, and an extra beta release has been slotted in to allow for additionaltesting.
Julia 1.13 released
Version1.13 of the Julia programming languagehas been released.

[$] Stabilizing Rust's never type
A function's return type is supposed to indicate the kind of data that itproduces. Rust's "never" type, which isdenoted by an exclamation mark ("!"), is the type the language uses to marka function that never returns and other places where a value can never occur. Fora long time, the never type was used internally by the compiler, but wasconsidered an unstable feature. OnAugust24, after more than two years of work,Rust-compiler-contributor "waffle" finally managed to stabilize the type. Ittook so long, in part, because it involved a small breakingchange to previous Rust editions, which the compiler maintainers needed toensure did not impact much real code.
Jellyfin 12.0 released
Version 12 ofthe Jellyfin media-management system hasbeen released.

[$] CERN's migration path from CentOS Linux to Debian
The European Laboratory for Particle Physics, usually just called CERN, is not only the birthplace ofthe World Wide Web, it is home to the Large HadronCollider (LHC), the world's largest and highest-energy particleaccelerator. As such, its computing environment is both truly unique and ofgreat interest to people outside of CERN who hope to find lessons applicable totheir own computing needs. The upcoming migration of some of CERN's systems fromCentOSLinux to Debian, which was the topic of a talk at the recent MiniDebConfWinterthur2026,is of particular interest.

[$] Fixing the TCMalloc regression with RSEQ operations
The restartable sequences feature is one ofthe stranger corners of the kernel's user-space interface; it provides away for user space to carry out simple lockless operations and be informedif it is preempted over the course of an operation (and must, thus,restart). Work merged in the 6.19 release to improve the performance of restartablesequences broke the TCMalloc allocator,which was relying on an undocumented (and unintended) kernel behavior.Now, Olivier Dion is proposing anaddition to the restartable-sequences API that will bring TCMalloc backinto the fold; it does not make the restartable-sequences API any lessstrange, though.

[$] Deterministic testing for multithreaded Python
Python's support for multithreaded programs has improved considerably overthe last few years with the advent of the "free-threaded" version of the language. Buttesting multithreaded programs is notoriously difficult, because theunderlying host system determines the thread-execution ordering, which addsan element of non-determinism. At PyCon US, Larry Hastings gave a talk (YouTube video)about his blanket project,which is meant to provide mechanisms for deterministic testing ofmultithreaded Python code.

[$] Recent work in memory tiering
Tiered-memory systems are built with multiple types of memory, each ofwhich has different performance characteristics. In addition to the usualDRAM, a tiered system might also provide faster high-bandwidth memory orslower CXL memory. On these systems, the placement of memory allocationshas a significant effect on the performance that a workload will obtain.While work on tiered-memory improvements has been ongoing for years, itfeels like the pace has slowed a bit recently. Even so, there are a fewefforts underway, but they are facing questions about whether the tieringdesign makes sense.

[$] Securely suspending LUKS-encrypted disks
When a laptop is asleep, its memory is not unreadable. The righttooling can attach to the computer's memory bus and read out its contents, andcold-boot attacks can theoretically read values from memory for a short timeafter the computer loses power. Thatis really an unavoidable fact about the hardware, but some users would stilllike to ensure that, even if this happens, their long-term encryption keys, such asthe key for full-disk encryption, remain unreadable. In June2026, IngoBlechschmidtdiscovered that Linux kernel versions after 6.9 (released inMay2024)were not erasing disk-encryption keys when a laptop was put to sleep, evenwhen configured to do so. He quickly identified a potential fix, which has beenmerged, but it was not a comprehensive solution.
