Hello, internet. I am making one of those videos where you sit in a chair and
directly address the camera about a serious subject. I know it's not in my
wheelhouse, and there are people who do this way better. And in fact, that's the
reason I'm making this video is that something happened last week that I really
wanted to see people make this kind of video about, and nobody did. So, I'm
hoping that I can generate some attention for it and some interest in this topic
so that people will cover it.

This document was originally written several years ago. At the time I was working as an execution core verification engineer at Arm. The following points are coloured heavily by working in and around the execution cores of various processors. Apply a pinch of salt; points contain varying degrees of opinion.

It is still my opinion that RISC-V could be much better designed; though I will also say that if I was building a 32 or 64-bit CPU today I'd likely implement the architecture to benefit from the existing tooling.

Mostly based upon the RISC-V ISA spec v2.0. Some updates have been made for v2.2

Original Foreword: Some Opinion

The RISC-V ISA has pursued minimalism to a fault. There is a large emphasis on minimizing instruction count, normalizing encoding, etc. This pursuit of minimalism has resulted in false orthogonalities (such as reusing the same instruction for branches, calls and returns) and a requirement for superfluous instructions which impacts code density both in terms of size and

FreeBSD Jails with VLAN HOWTO

This article discusses how to set up jails on a FreeBSD 11-CURRENT system utilizing VIMAGE (aka VNET) to provide a virtualized independent network stack for each jail with support for VLAN tagging.

Torrents Time bundles certificates and private keys.

Torrents Time bundles certificates and private keys

So, with all the news about how Torrents Time is insecure.. I figured I might as well reverse it.

It seems to have three components, one (on windows) is a native service (TTService.exe) that runs as SYSTEM, another (TTPlayer.exe) runs under a lower privileged user. There's also a nodejs application, server.js.

The native service seems to set up a localhost HTTPd, on either port 12400, 11400, 10400 or 9400, using whichever is open.

So, I browsed to it, and was astonished to discover it was running with TLS, and gave the browser a valid certificate, signed by Thawte! (the cert was issued to localhost.ttconfig.xyz, obviously to work around new CA rules. For the record, it currently resolves to 127.0.0.1 as you'd probably expect.)
