gdgghhhhhon Btrfs/ZFS/bcachefs under workloads classic benchmarks skip

In case someone wonders why bcachefs is sadly no longer part of the mainline kernel. Start reading here: https://lwn.net/Articles/1027289/

gdgghhhhhon Grit: Rewriting Git in Rust with agents

So, they "decided" it's not a derivative and thus can be listened under MIT instead of GPL....

gdgghhhhhon Local privilege escalation via execve()

https://nvd.nist.gov/vuln/detail/CVE-2026-21250

gdgghhhhhon Unix v4 (1973) – Live Terminal

Oh. I was not aware of that

gdgghhhhhon Unix v4 (1973) – Live Terminal

/proc is a Linux thing.

gdgghhhhhon Bcachefs Goes to "Externally Maintained"

It's amazing how many of the "experts" here don't get that bcachefs != btrfs

gdgghhhhhon Hardening Firefox – a checklist for improved browser privacy

Also consider putting Firefox itself into a jail. E.g. using bubblewrap on Linux: https://gist.github.com/richardweinberger/cae9edeafeec4cdf65...

gdgghhhhhon Possible GPL Violation by Banana Pi RiscV

FWIW, the missing source has been released.

gdgghhhhhon Bcachefs may be headed out of the kernel

In this context, this is worth a read: https://hachyderm.io/@josefbacik/114755106269205960

gdgghhhhhon German Blogger fefe is absent

politely, yes.

gdgghhhhhon Parsing JSON in 500 lines of Rust

I wonder how well it works with heavily nested files. AFAIU, this is a recursive parser.

gdgghhhhhon Why does Mill use Scala?

The title really confused me until I realized this has nothing to do with https://millcomputing.com/ :-)

gdgghhhhhon I miss Vim

Speaking of helix, does is support vim key bindings? Last time I tried, it was kinda disappointing to be forced to learn a completely key binding set.

gdgghhhhhon Is XYplorer really written in VB6?

I wonder how the code looks, it must be a maze of "on error goto" lines to not crash at the slightest error.

gdgghhhhhon Is XYplorer really written in VB6?

The program doesn't look like a typical VB6 application, I guess the author draws all UI elements himself?

gdgghhhhhon Linux CoC Announces Decision Wrt Kent Overstreet (Bcachefs)

No Kent, really.

gdgghhhhhon Linux CoC Announces Decision Wrt Kent Overstreet (Bcachefs)

I suggest reading the whole mail thread before judging. The CoC decision was the last resort.

gdgghhhhhon The optimised version of 7-Zip can't be built from source

Don't get me wrong, OSS does not mean it will build in any random configuration on any distro. The source is there. Maybe 7zip could do better, but still...

gdgghhhhhon Finding out where syscalls are called from: Stack traces with strace

Perf trace is also worth noting. It was much less performance overhead than strace. https://man7.org/linux/man-pages/man1/perf-trace.1.html

gdgghhhhhon Pseudo Graceful Process Termination Through Code Injection

Since you are writing to the location where rip is pointing to, you need to rewind to the beginning of the page first. Otherwise the program will crash if you're unlucky and rip is currently exactly at the end of an executable mapping. Low chance, but still...

gdgghhhhhon Pseudo Graceful Process Termination Through Code Injection

One use case I have faced more than once are stuck processes in legacy build systems. For example, generating docs takes ages. Just killing the generator process will fail the build because the parent will notice. And since the build system is buggy/old, restarting the build will start from zero.

gdgghhhhhon NAND Error-correction Code

To support a block based filesystem on top of MTD an advanced FTL (Flash Translation Layer) is needed. Sadly most algorithms for decent FTLs are patented. SSD vendors try hard keeping their magic sauce there own. In Linux we habe some trivial FTLs implemented, but even these are toxic.

gdgghhhhhon Diskomator – NVMe-TCP at your fingertips

I don't get it. Isn't this just a live CD that setups nvmt like described here? https://blogs.oracle.com/linux/post/nvme-over-tcp

gdgghhhhhon Analyzing Packet Drops Without Tooling: Or Ftrace the Pure Way

My best guess it's the animated SVG. Maybe it should get lazy loaded.

gdgghhhhhon A gentle introduction to static analyzers for C

There is also smatch, it is used by the Linux Kernel community https://github.com/error27/smatch

gdgghhhhhon No Love for Negative Permissions – DAC/ACL Bypass on Linux

Funny to see them used as example by a tutorial from Red hat:

https://www.redhat.com/sysadmin/linux-access-control-lists

gdgghhhhhon Restricting network access using Linux Network Namespaces

Just share an open FD to a socks proxy with the isolated service.

gdgghhhhhon SD Memory Card Formatter for Linux

So what? Don't get ne wrong, tuxera is cool but this still does not make it free software.
