I’ve been thinking of trying to use NetBSD a bit more. Linux is just too easy. Support for recent hardware is not as good on NetBSD as it is on some platforms (though it depends exactly what hardware you have). The laptops page on the NetBSD wiki naturally recommends some fairly old Thinkpads. And mentions EeePCs. Not especially encouraging. That page could probably benefit for a bit more…
TLDR : github.com/ids1024/hello-hurd has a Hello World program using Mach RPC calls. I don’t really write blog posts much, but when I do, I take the opportunity to discuss the most relevant technologies one is likely to encounter. Like GNU Hurd. …Okay, some (very abridged) background. In the beginning, Bell Labs created heaven and earth. Bell said, “let there be light”, and there were lasers. And…
Rust is great for some many practical purposes in modern software development. But who needs any of that? What are the oldest things we can target with standard Rustc? ARM is a pretty well supported architecture, right? ARM is older than you might expect; it was first used in the Acorn Archimedes in 1987. Hey, I see LLVM’s code has mentions of the ARMv2 architecture that uses! Except… ugh, it…
UPDATE : I would probably talk about this different now that I know a bit more about how something like this would actually be formalized, but this post is an analogy more than an actual formal model, even if a variation can be formalized. There is a fair amount of confusion about what unsafe means in Rust, as well as debate about how one should think about it. Recently I’ve seen several blog…
NOTE: Currently the standard way to compile C or C++ to WebAssembly is to use Emscripten. Additionally, my loader code here is a quick test, and not complete nor necessarily entirely correct. Background With LLVM 8.0.0 , the WebAssembly back-end is no longer categorized as “experimental”. The LLVM linker, LLD, also supports WebAssembly. So with current releases of LLVM, Clang, and LLD, it’s…
TLDR : Scroll down for a pretty screenshot and a GitHub link. I’ve decided to take a look at Minix, which is an interesting microkernel OS. Naturally after building Minix from git , the first thing I decided to try was porting Rust’s std to Minix so I could cross-compile Rust programs from Linux to run under Minix. Okay, I suppose I could have started with something else, but porting Rust software…
This is a continuation of my earlier reverse engineering work. This time, I’ve succeeded in duplicated all of the remote’s functionality, other than things like firmware updating. Determining the Protcol It turns out my previous testing failed for a simple reason: I didn’t know the camera has to be set to a particular mode to use a remote. Specifically, self-timer/remote mode. After that, my…
I’ll begin with a word of warning: relying on the particular way fat pointers are implemented is bad, and may break. How bad? Except worse than that. What’s worse than a Velociraptor attack? Use your imagination. So beware that at any point the code here may stop compiling, segfault, and otherwise behave in weird ways, some of which involve Velociraptors. Now that that’s out of the way, what is a…
The Creative Sound Blaster E1 is a USB DAC and headphone amplifier. Additionally, it has a built-in microphone, and has two seperate headphone jacks, one of which can be used as a microphone input instead, if it is set as such in Creative’s software. Naturally, their proprietary program only works on Windows, so it is stuck in the default mode (both jacks serve as headphone ports). Let’s fix that.…
The new Canon Rebel t7i includes Bluetooth; it can connect either to the Canon Camera Connect app, or to the BR-E1 remote control. TLDR so far, I have only gotten it to pair, either as a phone or remote. But shutter release and the other features of the BR-E1 should be easily doable, if the correct commads can be identified. Logging Bluetooth commands from the app Recent versions of Android have…
Perhaps I could write a blog here… But as a start, my post GSoC Project: Making Redox Self-hosting, Final Summary on the Redox OS blog descibes the Google Summer of Code project I did this summer, and links to my eariler posts there about it.
Well, I haven’t been posting here much (or at all) have I? Well, I’ll start now. Maybe. But I am writing here now anyway. Whitaker’s Words is an interesting old command line program for analyzing the morphological form of latin words, as well as providing simple definitions. For example, here is what it outputs for the word “caesaris”: caesar.is N 3 1 GEN S M Caesar, Caesaris N (3rd) M [XLXBO]…
There are essentially two ways to create a website. The most popular method is to use a CMS such as Drupal, Joomla, Wordpress, etc. This method allows for web-based WYSIWIG editors for site content, extensions, user login, comments, and various other features. It is also slower and less secure. Each time a page is loaded, the server must generate the page, often with a php script. There are…
