Pragmatism in the real world
I've been writing a simple Swift command line tool called QuickSS. It's a single file swift file, that I compile to a standalone binaryusing: swiftc quickss.swift -o quickss To distribute it on modern Macs, I need to sign it and then get Apple to notarise it. Signing the binary To sign the binary, you need a "Developer ID Application" certificate from your paid developer account. If you don't have one there already create a new… continue reading.
I'm currently writing a script that notarises a macOS CLI app which needs to access a password. Rather than put it in an environment variable, I thought I'd use the 1Password CLI. This is the first time I've used it, so these are my notes. The 1Password CLI tool is call op. I installed it via Homebrew with: brew install 1password-cli Sign in You need to sign in. op signin As I have multiple accounts… continue reading.
We have an HP all-in-one scanner and printer that is on our local network. Recently, I was away from home and needed to reconfigure the scanning settings for unimportant reasons. Usually, when I'm not in the office, I use Tailscale to connect back to machines as required, but the printer isn't running Tailscale, so its built-in web app isn't directly available. To solve this problem, I set up Tailscale subnet route on the Linux box… continue reading.
I run a Tailscale network so that remote computers can access local services. I also have a Linux box at home on that network that advertises itself as an exit node and recently noticed that it wasn't working. I had some time recently to sit down and work out what was going on. My initial suspicion was that it was DNS related as a cursory search brought up lots of results related to DNS. However,… continue reading.
I'm a member of a number of groups that publish a magazine, either paper-based or PDF. I prefer the PDF version, so download from the website and then move to the relevant directory. Recently, I realised that I could use Hazel to do this for me. To take one example, the filename of the PDF that I download is of the format PE-{issue number}-web{some random characters}.pdf, for example: PE-123-web9j45s3gd.pdf. There's sometimes a hyphen after web,… continue reading.
On a server that I help to maintain, it has postfix installed for emailing results of cron jobs and other status updates. This was set up to relay through SendGrid as they had a 100 email per month plan and we send out significantly fewer than that. Unfortunately, SendGrid are retiring their free plan, so I had to move to a new service and picked SMTP2GO and so had to update the postfix configuration. As… continue reading.
I've had a few cases recently when I wanted to know the number of words that I had written. To do this, I've copied the text to BBEdit which displays the word count in its status bar, but this is a bit of a faff. I finally sat down and created a Shortcut for it that took 10 mins. This is the shortcut: The idea is that I want to select the text and run… continue reading.
On one of my servers here, I run a local Perforce P4 server for my son. He's a game developer and as they use P4 at work, he wanted to learn it in a sandbox and to have somewhere familiar to put his own work. Installation onto Ubuntu was easy enough and I provided access outside of our local network via Tailscale and all was well. Recently, I was doing some admin-stuff on the server… continue reading.
Earlier this year, Lorna spent some time updating rst2pdf's website to use Sphinx. The nice thing about Sphinx is that it uses restructuredText, the same as rst2pdf does, so we now stay in the same ecosystem. While, we could have continued using Jekyll, it makes much more sense for us to use the same markup language as we use for the main tool, and our manual is written in it too. With the Jekyll system,… continue reading.
When writing an OpenAPI specification, I came across the need for a particular property in an error response to be either a string or an object. This situation came about when validating a POST request that takes an items property that is a list of objects As a contrived example of a pet with accessories, consider this example request in curl: curl -X "POST" "http://api.example.com/pets" \ -H 'Content-Type: application/json' \ -d $'{ "name": "Rover", "items": [… continue reading.
