I'm hosting my blog and my private Ghidra server on my Synology NAS. The NAS and the ISP router are already always-on, so it "only" costs me ~20€/year for a domain name. Even accounting for the electricity and network I&

I've disabled it just now. I was basically only using it as an alias anyways. I did take some very basic precautions otherwise (its firewall is configured to drop all non-local packets but for TCP ports 80 and 443), but at some point I

I did get an email, but it was triaged under the update category inside Gmail and thus buried under a metric ton of other updates (the account is over 14 years old and it has accumulated a lot of crap over the years). That's totally on

Neat! Recently my Synology NAS failed to automatically renew its Let's Encrypt certificate for my domain name and the certificate expired on my blog. I caught it the next day when my GoAccess metrics cratered (took some time to figure

French news mentions that the alleged crime is atteinte à la probité or lack of probity. In other words, things like corruption, influence peddling and so on. There are scant few details available, but this might be something more serious

Here's another series of articles on reverse-engineering a DOS game, using the original toolchain as part of the process of decompiling it: https://neuviemeporte.github.io/category/f15-se2

As in C++'s constructors/destructors? That's against their stance on hidden control flow as stated on Zig's website.

There is a Rust front-end for GCC that is under active development [1]. If the chip vendors are not willing to develop and upstream a LLVM back-end then they can start contributing to it as an alternative. [1] https://rust-gcc.gi

If these architectures can't muster enough manpower to keep up with modern toolchains then they are living on borrowed time. Maintainers of active, modern development projects have a limited tolerance for anachronism before they say &q

I've written an ELF object file exporter as part of a Ghidra extension [1]. It's a bit finicky to get it right (toolchains assume that object files are valid and don't have much in the way of diagnostics), but these are fai

Do all decompilation projects for 90s video games out there aim for perfect matching? I get why perfect decompilation is a big deal, I'm just wondering if there are other approaches out there besides perfect decompilation in the comm

My Ghidra extension doesn't perform static recompilation, the bytes that are exported are the ones from the original program (except the ones targeted by a relocation). It's similar to a raw binary exportation, except you get a re

Thanks! I've been working on-and-off on this for the past 20 months. It's the third prototype, the first one was a set of Ghidra Jython scripts [0] and the second one was a fork of Ghidra [1]. [0] https://github.co

At one of my former jobs, some members of our dev team (myself included) had manager-spec laptops. They were just good enough to develop and run the product on, but fairly anemic overall. While I had no power over changing the laptops, I wa

I was actually inspired by the Zircon system calls from Fuchsia, which is a capability-based system. Operating on the current process or another one is just a matter of passing the correct handle to the relevant system calls. I'm not f

I've wondered if process creation on Unix could be overhauled by extending some of the existing syscalls to operate on a separate process rather than the current one: // dup2() a file descriptor to the destination proce

I can only hope the person who designed this USB power adapter will end up frying their phone, tablet or other electronic device with it for some karmic justice.

This sounds like something an ESP32 or other wireless-capable microcontroller could do. It would probably be easier to fit a system-on-module than an off-the-shelf single board computer in a crammed space.

If modern encryption is that big of a performance drag, would using a proxy that deals with the encryption sidestep that issue? With hardware that old and power-hungry, I'd expect a proxy hosted on a modern single-board computer in the

Couldn't the Baltic states switch synchronous zones by disconnecting from the Russian grid, blacking out and then bootstrapping using the European grid? That would break continuity of service and require a black start (far from ideal),

Not necessarily. Some roundabouts have the center circle partially paved so that oversize loads can drive right through if needed. There are curbs, speed bumps and road pillars that make it obvious for normal traffic not to take the shortcu

Over 20 billions of kilometers away? I'm not a RF engineer, but it's a fair guess that synthesizing the signal isn't going to be the problem, having the probes receiving it is another story.

I highly doubt an amateur has the means to contact the probes. Heck, I'm not even sure any organization besides NASA has antennas big enough for the job.

I'm not seeing much advice related to the target itself (PlayStation 1). That target has both embedded constraints (2 MiB of RAM, no MMU...) and platform-specific pitfalls that you don't see when targeting a modern system. Off the
