That doesn't follow. Firstly, I don't think I've seen any other SBC vendor fail to publish full schematics. This is a peculiarity of rpi's offering. Secondly, nobody is forcing them to add DRM chips to anything. That&#x2

That's true. I mainly cover this point - filesystems as a means of connecting different applications together - in another article: https://www.devever.net/~hl/nexuses

Author here. This is the case with *nix but doesn't need to be. As far as I'm aware, it's quite common in microkernel-based OSes to implement even ELF loading, dynamic linking, etc. inside system libraries loaded inside the p

Let's suppose that I have an HTTP endpoint for a doorbell (for some reason). The doorbell resource is represented as http://example.com/doorbell . There's no RING HTTP method, and I could invent one, but heaven kno

The trouble is, a tape drive can support seek(). But can it support it performantly for all arguments? seek(0, SEEK_SET) is easy. seek(1024, SEEK_CUR) is easy - just read forward a little. But seeking to some arbitrary fixed offset? As far

The whole point of my article was that constraining things to a small, limited set of verbs is actually a bad idea. Theoretically you can just make up your own verbs for HTTP and use those. In practice people stick to the common ones becaus

On *nix, you can always figure out what type of filesystem is mounted at a given prefix by typing `mount`. What the use of schemes does is make things needlessly inflexible, and embeds a dependency on the name of a filesystem provider insid

Personally, Redox's use of URLs seemed like really bad design to me. It doesn't get simpler than the Unix path syntax. Having a scheme:// makes sense for URLs because you don't otherwise have any contextual informat

This is pretty much what I mean. Essentially I'm proposing that the "base class" shouldn't support anything other than close(). You could have objects which don't support read()/write(), but custom verbs with d

Hold on a minute. Though the 737 MAX issues were caused by the desire to keep the same type rating, making the 737 MAX have a new type rating at this point won't solve the issue . The 737 MAX needed to retain the unusual fuselage desi

There weren't that many off-the-shelf tools involved, other than things like binwalk and disassemblers. My workflow can also be hilariously ghetto at times: I like to output hexdump -C to a file, then annotate that in vim. For example:

It is hugely ironic that this page is just a loading spinner if you don't have JavaScript enabled, so I have no idea what it says.

Intel said they'd open the Thunderbolt spec and make it royalty-free years ago, but only now are they actually doing it (by donating it to the USB-IF).

When we first heard this crash was due to a change in computer-controlled stabilizer behaviour, my question was "why on earth did Boeing do this?". Perhaps I didn't read deep enough, but the summary explanation that it was to

I'm talking about the patent licences for the ISA , not a specific core. Does the GPLv2 licence for the T1 confer a patent licence? If not, you'd probably need patent licences for the 64-bit ISA from Oracle to market something, A

My understanding is that only 32-bit SPARC is open. The 64-bit extensions are still proprietary, aren't they?

It's a connector for the optional FlexVer module they intend to release in the future. It's not OCuLink.

Er, no I wouldn't. Nobody is claiming that that forms part of an open hardware definition. And yes, PSU vendors aren't advertising their products as open hardware . I'm aware of this. So people shouldn't be making out t

I'm not seeing the schematics for the PSU here. There's plenty of detail I could hope for that's not there.

I actually thought of this. You could put the key on the disc, or publish it, or include it as a file on the disc in a standard location. But no dice: it turns out the encryption is managed entirely by the replication plant. The plant makes

The Blu-Ray video format is pretty cancerous in terms of DRM; there's not really any salvaging it. One of the most nauseating restrictions of all is that replication plants aren't even allowed to fabricate Blu-Ray video discs whic

What's particularly insidious about a lot of these link shorteners is the use of non-semantic redirects. That is, redirects which are not based on HTTP Location: headers but things like meta http-equiv="Refresh". I assume thi

It's a bit light on details in the ME and pre-real mode stages. For example, it omits to mention the 'Authenticated Code Module' which now executes before the BIOS reset vector.
