dezgeg··on OpenBSD has a use-after-free allowing local privilege escalation to root
I don't think this is about core kernel semaphores but rather the SysV semaphore system calls?
dezgeg··on Resetting Xbox
Ah, but you see Xbox security updates won't be for your security. They will be for protecting the console's security against jailbreaks etc.
dezgeg··on Fable 5 On Vending-Bench: Misbehaving, With Plausible Deniability
> Today I am filing: > 1. A payment dispute with the email payment processor for the 7/29 transaction of $451.15 > 2. A complaint with the FTC and California Attorney General (retention of payment without delivery) > 3. A small claims filing in San Francisco County for $451.15 plus costs

I wonder did their prompts include a fake location or have the models assumed that Silicon Valley is the center of the universe :)

dezgeg··on Potential session/cache leakage between workspace instances or consumer accounts
System prompt for something like Claude Code should be identical, no?
dezgeg··on The Apple Disk II Controller Card (2021)
The bottleneck was with the serial protocol between the drive and C64. It was done via bit banging in software due to some chip bug. The fastloaders replaced the protocol with something more amenable to bitbanging.
dezgeg··on The end of my AArch64 desktop experiment
That is the reality for huge amount of ARM powered hardware, unless you fancy running vendor forks of kernel, u-boot, etc.
dezgeg··on The end of my AArch64 desktop experiment
You can't if the firmware provided DTB doesn't follow any upstream Linux approved bindings and instead uses some vendor kernel specific bindings.
dezgeg··on Show HN: Bash4LLM+ – A lightweight, dependency-free Bash wrapper for LLM APIs
Have you actually tested the portability? MacOS ships an ancient bash version and neither mac or BSDs use GNU version of coreutils.

I'm also very doubtful performance of this would be faster than python, bash is very slow.

dezgeg··on Show HN: Decomp Academy – Learn to decompile GameCube games into matching C
Quite safe in practice, even Nintendo games have had no issues. GTA 3 / Vice City decompilers did get sued though, but IIRC mainly because they did not comply with DMCA requests at all.
dezgeg··on Show HN: Decomp Academy – Learn to decompile GameCube games into matching C
Yes, exact version of the original compiler is required.

Generally bit-for-bit equivalence to the original executable is expected. However I think for some cases where the original executable included debug info (eg. PS2 ELFs) then the unused-at-runtime sections need not match.

dezgeg··on How do you keep Web MIDI from crashing a 1983 synthesizer?
MIDI doesn't have RTS/CTS pins...
dezgeg··on GPT-5.5 hallucinates 3x more than MIT-licensed GLM-5.2
I have seen some pre-AI over-mocked codebases where the "tests" where essentially that (but harder to read than regex would have been)
dezgeg··on Ask HN: How do you separate intentional test boilerplate from real duplication?
Detect tests somehow (eg. in rust you could check for #[test]) and just skip the analysis for that function?
dezgeg··on I Hate Compilers
Even if it could, it would be ridiculously token inefficient to update huge amount of addresses instead when some small change is done to the middle of a binary
dezgeg··on Salesforce to Acquire Fin (formerly Intercom) for $3.6B
What does "long term memory" mean? It can write down notes from past/recent support requests? If so, that sounds like risk of one customer's data leaking to another.
dezgeg··on The 29th International Obfuscated C Code Contest (IOCCC) 2025 Winners
That's defined in Makefile
dezgeg··on wolfSSL releases a new product; wolfCOSE a zero alloc C embbedded COSE stack
Some stricter interpretations also require that maximum stack usage can be statically analyzed (ie. no recursion, no function pointers, no VLAs/alloca).
dezgeg··on Antigravity 2.0 Tops the OpenSCAD Architectural 3D LLM Benchmark
It requires a keyring service being installed (accessed over dbus) and if there isn't one it just silently doesn't store them anywhere. Pretty bad UX.
dezgeg··on Google's Antigravity bait and switch
It only stores credentials in the keyring, so if you have no dbus keyring service running it just silently won't remember them.
dezgeg··on Gemini CLI will stop working from June 18, 2026
But then you have to pay by the token instead of the subsidized subscription prices
dezgeg··on Debian must ship reproducible packages
Did you actively verify that your builds were bit-reproducible?
dezgeg··on Removing fsync from our local storage engine
You don't need to do that for every write though. Only when the database file is created.
dezgeg··on Dirty Frag: Universal Linux LPE
For home computers, essentially https://xkcd.com/1200/ applies.
dezgeg··on CARA 2.0 – “I Built a Better Robot Dog”
Reminder that this was a student project.
dezgeg··on Copy Fail
In wsl, each distro you have runs in a container (with lot of permissions), you'd need to apply the modprobe change inside wsl "hypervisor" rootfs
dezgeg··on Linux 7.0 Broke PostgreSQL: The Preemption Regression Explained
Even worse, the actual struct page on Linux is 64 bytes, so 4x your example
dezgeg··on Kernel code removals driven by LLM-created security reports
Do they use it via mainline Linux kernel's ISNDN drivers though (and not something proprietary)?
dezgeg··on Amazon won't release Fire Sticks that support sideloading anymore
GPL-3 dependencies are typically banned inside embedded device firmware. If a 3rd-party app uses those presumably it will be problem for the developer of the app, not Amazon.
dezgeg··on Solitaire simulator for finding the best strategy: Current record is 8.590%
Could there be mixup with FreeCell?
dezgeg··on Show HN: Unicode Steganography
Switching between NFC vs NFD could be even sneakier.
