I needed to set up a daemon for a service that’s in the low 1024 ports reserved for root on FreeBSD. However, I didn’t want to run the service as root. Instead, I set up pf (the firewall in BSDs) to simply redirect the port.

Fixing VisualEditor not being able to contact RESTBase server
If you set up a new wiki with MediaWiki 1.35 (since it adds the PHP-based Parsoid server), and you get this error trying to load VisualEditor:
Error contacting the Parsoid/RESTBase server: (curl error: 28) Timeout was reached
It’s because the server is trying to contact itself with the server name (hostname/IP). If it’s a DNS name, then make sure the name it uses resolves to itself; a quick fix was to add it to the hosts file.
Embeding application manifests into Windows executables as a resource
If your Win32 application needs to declare that is supports something before it even executes, this is where a manifest file comes in. While you can ship one with your application (in the form of appname.exe.manifest
), it’s more fool-proof to just embed it into your application. You can do so with
RISC-V isn’t as interesting as you think
I had wrote this before the Unleashed was revealed, so some of the bits on economics have changed. As of writing this, I still stand by my other beliefs. One of the most hyped things in hardware design is RISC-V, the open ISA available without license fees. Many organizations including Western Digital have pledged support for RISC-V, and the open source community has a lot of faith in it, and with Nvidia’s recent purchase of Arm, people are concerned. However, I feel these hopes are somewhat misleading, as RISC-V’s openness is less at the benefit of the user and more for CPU vendors.
Brief thoughts on Princess Mononoke
Princess Mononoke has been talked about a lot elsewhere – why wouldn’t it be? It’s a great movie that everyone should watch. What I want to talk about briefly is the motivation for characters, and how they put many “prestige TV” dramas to shame in terms of complexity. Spoilers below the fold!
Continue readingUsing EFI labels on FreeBSD
A quick post since this isn’t well covered: FreeBSD on EFI systems still will hard-code the name enumerated at install time (like da0p2
). There is a better way than using glabel
(which injects itself into the last block of the partition, which can be problematic). Instead, you can use GPT labels, which are cross-platform and well-known.
FreeBSD 12.1 on a QNAP TS-251
I had recently gotten such a NAS for dirt cheap (they didn’t know what they had!), and wanted to put it into useful service. The specifications include a Celeron J1800, and mine had been upgraded to 8 GB of RAM in its past life.
The OS on these things (QTS) is bizarre; basically a homelab in a box, but it’s sludge. The UI is some fake desktop thing, in the vein of eyeOS/YouOS of old. There are servers for things like LDAP, MariaDB (recommending you use phpMyAdmin…) and RADIUS, but I’m not sure who would even use them. There’s even an X server running, for some reason – with IR remote support! This thing is really a low-end SMB-for-SMB and Plex box through and through. I didn’t really like the OS though, so I decided to load something else on.
Continue readingARM64 programs built with Visual Studio crash with 0xC000007B
It’s because Visual Studio seems to copy an x86 version of the VC++ runtime into system32 on ARM64 systems. That’ll make it crash with a bad image format error. If you copy the ARM64 version of vcruntime140.dll
(for me, found in C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Redist\MSVC\14.28.29325\arm64\Microsoft.VC142.CRT
) into the build directory, binaries will work.
Notes with the Parallels Beta on Apple Silicon
QEMU recently gained Apple Silicon hypervisor support. That was pretty damn cool for the first few weeks of M1 in people’s hands. Even without any optimizations, Windows 10 on M1 outclasses the Surface Pro X and even my Ryzen gaming desktop. Unfortunately, that didn’t include 3D acceleration (though virtio-gpu is now a thing for 2D).
Luckily, Parallels has ported their virtualization software to M1. It’s incredibly janky (and certainly deserving of a technical preview because of that!), but shows a lot of promise, complete with D3D11 support for games. Unfortunately, it requires some hacks to get running stable, but it’ll work fine after that.
Continue readingEconomics Has Become a Spiritual Thing: How David Byrne Predicted Open Source and Startups
Here’s a post off-the-cuff (and not what I usually write): True Stories is one of my favourite movies that never gets talked about. It’s got everything – Talking Heads songs done better than the album, observing the state of the American suburbs of the 1980’s, and bizarre monologues. What’s not to love?
The scene I want to talk about the most though, is the scene where Byrne has dinner with a local businessman (the kind revered for contributions to their local and small community) and his family. It’s one of the most amusing scenes, but also the most prophetic – particularly for people in the computer business.
