When the IBM PC first came out, it was little more than a toy. The serious people had Sun or Apollo workstations. These ran Unix, and had nice (for the …read more Continue reading Relive the Glory Days of Sun Workstations
Virtualizing computers is nothing new. However, Apple devices always present challenges. Just ask anyone who has built a Hackintosh. At least computer hardware is usually exposed, but on phones, the …read more Continue reading Virtualizing iPhoneOS 1.0
With the advent of super powerful desktop computers, many developers make use of some sort of virtual or psuedo-virtual machines (VM). We run Windows in a VM and do kernel …read more Continue reading Debug ARM Virtually
Our Sun is getting a bit frisky these days, and has rewarded us with perhaps the best screensaver image ever taken. The incredibly detailed photo of a sunspot was actually taken back in January by the Daniel K. Inouye Solar Telescope, a 4-meter instrument with adaptive optics that can image …read more
Taking things apart to see how they work is an important part of understanding a system, and that goes for software as much as for hardware. You can get a jump start on your firmware reverse engineering skills with Asmita Jha’s workshop which was presented live at the Hackaday Remoticon. …read more

Choosing the perfect Linux distribution that satisfies your personal needs and likings can be an impossible task, and oftentimes requires a hint of Stockholm syndrome as compromise. In extreme cases, you might end up just rolling your own distro. But while frustration is always a great incentive for change, for …read more

It’s said that slow internet is worse than no internet at all, which is mainly a matter of continuously crushing all hope and sanity vs. finding peace in accepting a fate out of your control. Plus, you can easily pass the time of being catapulted back to the prehistoric ages …read more
When we first saw [Ben Jojo’s] post about the Internet inside EvE Online, we didn’t think we’d be that interested. We don’t play EvE — a massively multiplayer game. But it turns out, the post is really about understanding BGP (Border Gateway Protocol) and how it helps route traffic in large networks. The best part? He actually simulates a network with 8,000 nodes to test out what he’s talking about.
Obviously, you wouldn’t want to fire up 8,000 Raspberry Pi computers for such an experiment. Using Buildroot, he set up a very small Linux image that had the bare minimum …read more
Programming languages tend to polarize, and Rust is by far no exception. Whether it will stick around and grow as an alternative for the lower levels or not — time will tell. In the meantime, if you’re curious about the language and its low-level abilities yourself, [phil-opp] has written a series of blog posts on building your own little bare metal kernel in Rust.
Starting from the basics, [phil-opp] describes in detail the set-up and build process to create a standalone executable that won’t be linked against the Rust standard library. From here he proceeds to build a simple operating …read more
Writing an operating system is no small task, but like everything else it is easier than it used to be. [JSandler] has a tutorial on how to create a simple operating system for the Raspberry Pi. One thing that makes it easier is the development environment used. QEMU emulates a Raspberry Pi so you can do the development on a desktop PC and test in the virtual environment. When you are ready, you can set up a bootable SD card and try your work on a real device.
The operating system isn’t very complex, but it does boot, organize memory, …read more
