Homelab Learnings

My experience running IT infrastructure at home, with some recommendations foranyone starting out on their Homelab journey. I ve been running a home server of some kind for more than 20 years. It started when I was at university, hosting a website on an old PC to share party photos (this was in the days before [ ]

Compressing a PDF file on macOS

Sometimes people create PDF files with large images, resulting in files that are too large to email or sometimes even upload on web forms. A quick and dirty way to compress such files is using ghostscript in a terminal, which you can install on macOS using homebrew (brew install ghostscript): Replace myfile.pdf with the file [ ]

Samba config for Apple Time Machine

I ve been using samba s vfs_fruit module to enable backing up my mac laptop to my ubuntu-based NAS. I ve found the configuration fiddly, and it occasionally breaks with macOS upgrades. Anyway, I thought I would document my settings in case it helps anyone else out there. The file system backing my Time Machine share is ZFS, [ ]

ZFS compression and encryption

Up until a recent overhaul, I was using btrfs in raid1 to manage the 4 drives I had in my NAS. However it s been clear for a while that the momentum is behind zfs. It has more features, better stability, and generally inspires much more confidence when things go wrong. btrfs still has its place [ ]

Auto-focusing a Canon EF 135mm f/2L with the Sigma MC-21 on a Panasonic S5 II

When I searched myself before getting the Sigma MC-21 EF adapter I didn t find much information on using this particular combination, so I thought I d report my findings. This is not a scientific test, just my impressions after using it for a while, and comparing it subjectively to a 5D mark IV. I ve also tried [ ]

Vaccine Scepticism is stupid, but not for the reason you might think

Recently I was sent a video by a certain Dr John Campbell titled Immunology of mRNA vaccines , which I won t link to here, but it essentially casts doubt about the safety of mRNA vaccines with no evidence or sources whatsoever. In a discussion with a fellow retired crank named Robert Campbell, he leaps to unlikely [ ]

Home Server – new HBA edition

Some long time readers of this blog may remember my home server articles, the most recent being Ubuntu Home Server 14.04 A DIY NAS . There haven t been any more recently because there s not been much to report. The server described in that article, built in 2014, has been backbone of my home network ever [ ]

Age vs Crypto

1. Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works.2. Anything that s invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.3. Anything invented after you re thirty-five [ ]

Keybase – sadly it’s time to jump ship

Because the captains did a while ago. Exhibit A the github activity graph for the keybase client: Development basically ceased in 2020 when the team joined Zoom. This means no further improvements, including support for Apple Silicon. This was a skills acquisition for Zoom no doubt they needed the talent after they were [ ]

A Brief Review of Beer52

Our company uses Perkbox as an employee benefits program. It has some nice freebies, but on the whole I find it s mostly marketing I.E. benefits that make little sense except as paid promotions. So while I was happy to see a get a case of craft beers delivered free as one of the employee [ ]
