For OSS work, I work with two git remotes: upstream: the canonical OSS project repository, where main is the default branch and is what gets released. origin: a personal fork. All my feature branches live here. I set up locally like this: Fork the project repo to my account. Clone my fork locally, so the origin remote is my fork.…

I have a new project where we will be integrating with a third party API that is currently being written. Due to Conway's Law, we are being sent new versions of the OpenAPI spec as a set of JSON files via email. I quite like seeing the HTML rendering of an OpenAPI spec when reading it and understanding it, so…

Recently I discovered that this code passed our PHPStan level 10 checks: use http\Exception\InvalidArgumentException; // ... throw new InvalidArgumentException; I was surprised as http\Exception\InvalidArgumentException is not a class in our system. While cooling, I discovered that there's an http PHP extension and it appears that PHPStan has a stub for this which means that it accepts it as existing even…

Today has been a struggle entirely due to my own internal negative thoughts and feelings about impacting events that are outside my control. Navigating this to come out stronger rather than letting it consume my self-belief and confidence isn’t easy, especially at the time. I’m not worse at my job and my abilities haven’t diminished, but sometimes it’s hard to…

I don't often post personal things here, however last weekend my dad died peacefully in his sleep and it feels important to acknowledge this. I have no words.

As we reach the end of 2025, I take this opportunity to look back over the photos that I have taken and thing about the year. This year I published 1,064 photos to Flickr with, of course, at least one photo every day as part of my Project 365. The lovely thing is that my photos remind me what happened…

I've recently upgraded my MacBook Air to macOS 26 Tahoe and one thing I noticed was that Rodeo's rules were no longer working. With the help of exiftool, I worked out that when exporting to JPEG from Photos for macOS 26 Tahoe, the Object Name, Caption-Abstract and Keywords IPRC properties were no longer being populated. This is a regression from…

Sometimes it's helpful to add some text to my current Obsidian daily note without having to switch to Obsidian, find the daily note and then type my text. To do this, we can use the magic of Obsidian's obsidian:// URI schema and automate the text capture in Apple Shortcuts, with an assigned keyboard shortcut to activate it. This is the…

I've set my Mac up such that video calls such as Zoom use the microphone and earphones attached to my Behringer UMC204HD, which all other audio plays through the my normal speakers which are the default. One issue I have with this is that it's quite hard to change the volume when a call as the volume buttons on the…

I use OpenIn to open links in a given browser when I click on them in other applications. This is really helpful to keep various work related stuff in different browsers or profiles and I find it very helpful. One thing that's bothered me is that links from the Jira Cloud Slack App ignore my OpenIn rules and always open…

After pulling a new version of the Docker PostgreSQL container, I started getting this warning: WARNING: database "dev" has a collation version mismatch DETAIL: The database was created using collation version 2.36, but the operating system provides version 2.41. HINT: Rebuild all objects in this database that use the default collation and run ALTER DATABASE dev REFRESH COLLATION VERSION, or…

I use bash's history all the time, via ctrl+r and also with the up and down keys; it's wonderful. Sometimes, I want to get back to the end of my history and I recently discovered that there's a shortcut for this: meta+>. It doesn't matter where you are in your history, pressing meta+> jumps you to the end and you…

Following on from my earlier exploration of JWKS (RFC7517), I found myself needing to convert the JWKS into PEM format. This time I turned to Python with my preference of using uv with inline script metadata and created jwks-to-pem.py. The really nice thing about inline script metadata is that we can use the cryptography package to do all the hard…

Recently, since getting a new computer, I've noticed that I've been losing bash history items and it took a while to work out what was going on, though I'm still not completely sure as it never seemed to be so much of a problem. I regularly use the up and down keys with context specific history. For example, I will…

One project that I'm working on uses RFC 9457 Problem Details for HTTP APIs for its error responses.

Inspired by John Gruber mentioning on the Cortex podcast that he has a shortcut that saves links to a note in Tot, I thought I'd do something similar for saving to a note in Apple Notes. I want to store as a bullet item containing the name of the page, the link and the date. Something like this: (Funny that…

One app that I find incredibly useful is SwiftBar and one use I have is to display track info for the currently playing song in Apple Music. SwiftBar plugins work as shell scripts that execute on a timer and echo specially formatted text which SwiftBar then turns into an item on the menu bar with an attached menu I use…

I run Apple Music on my Mac desktop and send the output to my HomePod minis. To control the volume, you need to manipulate the Apple Music volume slider rather than the global volume controls for the Mac. It's easier to press buttons than use a mouse, so I used Keyboard Maestro to respond to two buttons on my Stream…

I'm working on a NestJS project that uses monorepo mode. It consists of a number of separate microservice applications that each have their own Docker container that are managed in development using Docker Compose. I like step-debugging in my IDE and so needed to set it up for this application. This is what I did. The application setup Each service…

Back in 2016, I wrote about using QuickGrab to take a screenshot of the active window via a single key press with no mouse use required. It's now 2025 and I'm still using this and Apple has announced that Rosetta 2 will be phased out in a couple of years. As QuickGrab is one of the few Intel-only apps I…

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…

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…

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…

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…

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…

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…

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…

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…

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…

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…

On the Roave Discord recently, there was a discussion about not breaking BC in interfaces inspired by this post by Jérôme Tamarelle: It's clearly true that if you add a new parameter to a method on an interface, then that's a BC break as every concrete implementation of the interface needs to change their signature. However, Gina commented that you…

While it would be nice to put the genie back in the bottle, that hasn't happened often in human history, so for the foreseeable future, AI in the form of LLMs are here to stay. I imagine that what we use them for will change over time as we collectively internalise their limitations. Personally, I'm now using them for my…

To provide consistency between the environments of our developers, I'm a strong proponent of using containers so that every developer is using the same versions of our tools. This is really important for command line tooling that depends on a separately installed language such as NodeJS or PHP as a simple npm i -g can install wildly different versions if…

One of the projects that I'm working on at the moment uses Stripe which means that we need to handle web hooks in order to ascertain what's happened as that's how Stripe communicates back to us. For production and staging, it's easy enough to register a url on Stripe's dashboard, but when developing, it's a little more complicated as our…

With the release of macOS 18.4, Safari no longer shows a padlock when you visit a website that uses https. I assume there's a reason for this but I was scratching my head trying to work out how to view the SSL certificate when I went to a new-to-me website domain that my bank asked me to go to. This…

With the recent release of the new OpenAI ChatGPT that can do image generation, I thought that I might add a feature image to my last blog post. I've had mixed experiences of AI generation of images, probably because I'm not good at prompting them. I started with this: We now have an image, but it doesn't have a credit.…

I'm using Signal more now and as it's fully end-to-end encrypted, if something goes wrong with your phone or you lose it, you will lose your entire message history. Signal on Android has an official backup method, but there isn't one for iPhone or desktop. As a result, a number of backup tools have been written by various people. The…

As a hobby project, I've been writing a screensaver for my Mac that displays my photos with a caption and date taken. To get the width and height of the screen so that I could size the image correctly, I used this code in my ScreenSaverView: self.screenWidth = frame.size.width self.screenHeight = frame.size.height However, I discovered that with two or more…

By default, the first user that you create on macOS is an administrator and has more power over the system than a normal user account. The reason it does this is obvious as you need this power to create other users, to install software and so on. However it also means that the computer is slightly more vulnerable to attack…

I was helping a friend set up a new website and hit a problem where the website was in an infinite redirect loop: I could see this in curl quite easily: $ curl -I https://myfriendswebsite.example.com/ HTTP/1.1 301 Moved Permanently Location: https://myfriendswebsite.example.com/ To debug, we turned off Cloudflare by setting the Proxy status on the DNS record in Cloudflare's admin to…

One of the bigger changes in PHPUnit 10 was the introduction of the new extension system which replaced listeners and hooks. The old way On one of my projects we have a TestListener that sets up the database before we run some functional tests against it.

There is a different between OAuth scopes and roles. A scope is the abilities that the client requests that the user can then decide if they are going to authorise that client to do those things. A role is the rights that a given user has within the application. Scope examples are "read-name", "read-address", "read-email", 'write-all", etc. Example roles might…

I recently had a problem with a failing Playwright test that only happened when running in Docker. The test that was failing was: let locator = page.locator('a[href="/login"].nav-link'); await locator.click(); await expect(page).toHaveTitle(/Log in/); The test clicks the link to go to /login and then checks that the next page's title contains the text "Log in". Not an especially complicated test, so…

One very minor thing that's been bugging me since macOS Sequoia came out is that if you launch an app that lives in your menu bar, but also has a hidden Dock icon a second time, then the Dock icon will re-appear. This happens to me a lot because I use Alfred to launch apps and also to bring an…

I create a fair few scripts in my ~/bin/ directory to automate tasks. Since discovering uv and inline script metadata, I've started using Python far more for these. As ~/bin is on my path, I want to run the script by calling it directly on the command line. To do this, I use this shebang: #!/usr/bin/env -S uv run --script…

My preferred calendar app for the Apple ecosystem is Fantastical as I've found that it meets my needs well. One minor irritant is that the editor popover defaults to a collapsed view and I have to expand it to see everything, in particular the notes field which I use frequently. I recently discovered that there's a hidden preference to change…

One thing that I've found helpful is to add a set of patterns to my global git ignore file (config/git/ignore for me) that allow me to create temporary files that are automatically excluded from git. The patterns I use are these: # Ignore a file by renaming it with ignore its name *.ignore ignore.* *.ignore.* This lets me create a…

When I'm on a Zoom or FaceTime call, I want stop all notifications on my Mac so that I'm not distracted by them and would like this automated. It's not easy to tell when a call is happening, so I simplified the problem to stopping all notifications if the Zoom or FaceTime is running as I only run these apps…

As usual, at the end of the year, I look back over the photos I have taken and think about the year. This year I have published 1162 photos to Flickr.

Thanks to Kyle and Lorna, we've moved rst2pdf's development out of the dark ages of setup.py and into uv with pyproject.toml.

I recently discovered the /usr/libexec/corebrightnessdiag command line tool on macOS.

We recently changed ISP to Aquiss who could not have been more helpful with pre-sales and support for the change over from BT Internet. Aquiss do not provide a router, so I removed the BT Smart Hub and put in a Ubiquity UCG-Max and connected it up to my existing AC Pro Ubiquiti access points. Obviously as it was a…

I recently acquired an Elgato Prompter which acts as an additional screen on my Mac. It does this using DisplayLink and the DisplayLink Manager app needs to be running. A new security feature of the newer macOS versions is that when your screen is being recorded, an icon is displayed in your menu bar. It looks like this and cannot…

I've been playing with different Ethernet network adapters to see if I can maximise the throughput to my Mac as my ethernet didn't seem particularly faster than WiFi. To test the speed, I want to use my internal network only as going onto the Internet will create too many variables. iperf3 is the solution for this. Running the test To…

For some work I'm doing, I have been given access to a Linux box that is part of a legacy production system.

Earlier in the year, I wrote about updating Flickr metadata using Python. For this script to work, I needed to install the flickrapi package first. I recently came across PEP 723 – Inline script metadata that makes this much easier for single file scripts like my sync-flickr-dates script. Essentially, we can now put a special comment block at the top…

There's a new feature in macOS Sequoia that allows mirroring of your iPhone to your Mac. This is a nice feature that allows you to fully interact with your iPhone as an app on you Mac's desktop.

I recently installed Python 3.13.0 rc2 to test rst2pdf against it and found that I couldn't install PyMyPDF which is required for the tests. $ pip install pymupdf ... This is because for a pre-release version, binary wheels are not provided to PyPI for the mupdf dependency which is written in C++. Hence, the compiler needs the headers. On my…

When Guzzle throws BadResponseException, the message includes information about the method, URL response code and then a truncated part of the body.

Unsurprisingly, uploading files with Slim 4 is pretty much the same as for Slim 3 as they are both use PSR-7 for Requests.

It's common to use a UUID when you need a primary key for your database records. Unlike incrementing numeric keys, it has the advantage that it's not tied to a specific database instance and can be created before insertion into the database. Usually, people use version 4 UUIDs, which contains a lot of randomness to ensure that it's going to…

I'm a huge fan of making my life easier and one thing I have found really helpful is automatic text substitution.

My personal preference is to prefix…

I've been doing a few updates to Daily Jotter, my little Mac app that's available in the Mac App Store. It's been a little while since I last updated it and a few things have changed.

When printing output in a shell script, it's quite useful to be able to indent information to group it. The easiest way to do this is with pr, like this: body=$(curl -s "http://localhost:8888/") echo "Response:" echo "$body" | pr -to 4 This generates: Response: { "links": { "games": "/games" } } Given that pr appeared in version 1 of AT&T…

When I write integration tests with PHPUnit, I find it helpful use Monolog's TestHandler to check that the logs I expect are generated. It's reasonably common that classes that write to a log take a PSR\Log\LoggerInterface in their constructor and then use that for logging. This usually logs to the error handler for pushing to Sentry or whatnot. This makes…

When writing a shell script recently, I realised that it would be really handy to get the the status code from a curl command in addition to the body.

I recently released a new version of rst2pdf. We don't do this frequently and it would be very easy to get it wrong.

My accountant recently moved my business accounts system over to FreeAgent. One thing I like to do is keep a copy of every invoice PDF that I issue in a folder on my computer as a back up, just in case the online systems let me down. As I was learning new systems, I took advantage of this time to…

One thing that I like to do is write a script for seemingly trivial things that I do more than once. I do this as it turns out that I end up needing them again. One example is a pair of script I use when testing rst2pdf. rst2pdf's tests work by creating a PDF and then comparing this to a…

I've always been a huge fan of the command line and have been using the gh command line tool to access GitHub for a while.

I wanted to stash just the unstaged changes in my git repo. There's a git stash --staged which will stash the staged files, but I didn't see an equivalent to stash just the unstaged ones.

With some commercial projects, it can be useful to know that all your dependencies have licences that your organisation deems acceptable. I had this requirement for a few clients now and came up with this script that we ran as part of our CI which would then fail if a dependency used a license that wasn't allowed. This proved to…

I install Python apps on my Mac using pipx like this: pipx install rst2pdf This will then install rst2pdf into its own isolated environment so that its dependencies do not affect and are not affected by any other Python app I have installed. Internally, it creates a venv at /.local/pipx/venvs/rst2pdf with symlinks to the currently installed python in the bin…

In order to verify a JWT created with an asymmetric key, the verifier needs to get the correct public key. One way to do is described in RFC7517 which describes the JSON Web Key format. Within the header of the JWT there is a kid property which is the key ID which is then used to find the correct key…

The most common use of JWTs is as an authentication token, usually within an OAuth2 workflow. Creating these tokens is part and parcel of the authentication library that you use. I recently had a requirement to use a JWT independent of authentication and these are some notes on what I learned when researching with Lcobucci\JWT. Make up of a JWT…

One annoyance I had with my external USB hard drives is that they weren't sleeping when idle which makes them noisy. We can't have that! My first port of call was hdparm and its -S parameter: sudo hdparm -S 60 /dev/sdb However this didn't help. Fortunately, I found hd-idle which worked! After installing, you need to edit /etc/default/hd-idle and change…

I recently added a second SSD to my Linux server and had to look up how to format it and set it up, having not taken notes for the first one. These are the notes I took the second time. This is all done from the command line and the monospace text is to be typed directly – though change…

Shortly after building a script to create binaries for Rodeo, my command line Flickr uploader, I realised that I could use a Github Actions workflow to run it and attach the created binaries to the Release page once I had created it. This is what I did. Trigger on release A GitHub Actions workflow is a YAML file and each…

Last week, I attended PHPUK 2024. This is one of the major PHP conferences and I was pleased to speak about DDD there. Sam and the team did a fantastic job this year with the videos already published. To my mind, attending a conference provides a number of benefits. The first and most obvious one is that you learn some…

One nice thing about Go is that it can cross-compile which allows me to use my Mac to build binaries for different operating systems. This is increibly useful for providing binaries for Rodeo, my command line Flickr uploader. To do this we set the GOOS and GOARCH environment variables before calling go build. For example to build for x64 on…

When I was building Rodeo, my command line Flickr uploader, one thing I wanted to do was set the version number that you see when you type rodeo -v to the correct version when I build the application for release. The basic process I wanted was: Tag git repository with new version number and push Build rodeo with that version…

I have a Linux-based server that acts as my Plex server amongst other things. It's fanless and I added an additional SSD for to hold the media data so it is nice and quiet. I'm a little bit of a belt-and-braces person when it comes to backing up my data, so in addition to backing up to the cloud, I…

I upload lots of pictures to Flickr and sometimes I just want to point at a file in Finder and upload it. Fairly recently, macOS introduced Quick Actions to Finder and this seemed like the ideal way to have a quick and easy way to upload an image to Flickr. To do this, the easiest way is to use Automator…

I regularly need to darken images for background use behind a title. I've been using a filter in Acorn, but finally decided to make it a script that uses ImageMagick so that I could simplify it all with Alfred. This is the script: darken-image.sh #!/usr/bin/env bash if [ -z "$1" ] then echo "Usage: darken-image [contrast=40]" echo "" exit 1…

I usually use my rodeo app to upload photos to Flickr, but for various reasons, I recently uploaded some photos directly via Flickr itself. One feature of rodeo that I really like is that it sets the date posted to be the same as date taken which means that they are ordered correctly in my photo stream. As this doesn't…

When creating my Year in Pictures post I decided that I wanted a montage of all the photos I had taken. In previous years, I've done this by taking a screenshot in an application where I try to set the zoom level correctly to get something acceptable. This time, I decided to do it properly and guessed that ImageMagick could…

As we finish 2023 and look forward to 20024, I have had an enjoyable time looking back at the photos I took throughout the year. As with the last 10 years, I have managed to take a least one photo every day as part of my Project 365, which allows me to remember what happened during this year of my…

For years, 19ft.com has been a hand-built static HTML website with a smidgen of PHP to set things like dates and include a header and footer to each page. While I haven't yet redesigned it, it seemed prudent to move it to a static site generator before I did so and I chose Hugo, mainly because as a go CLI…

I have a set of Markdown files with YAML front matter that contains a created property containing the date that the file was created. Due to various machinations, the file creation date no longer matches this date, so I thought I'd fix this. Setting created date of a file On macOS, to change a file's creation date you use SetFile…

For some automation that I"m writing, I need to get the Bundle ID for some Mac applications. The easiest way to do this is with AppleScript: osascript -e 'id of app "{Application Name}"' This can easily be turned into a bash script such as `bundle-id-of` like this: #!/usr/bin/env bash osascript -e 'id of app "'"$1"'"' And we can now obtain…

I'm a huge fan of ExifTool for manipulating EXIF data in images as it really is the Swiss Army knife for all things metadata related with images. Recently, I wanted to strip some privacy-related metadata from some photos; specifically location, people and keywords. That is, I wanted to keep the title, the camera settings, the creator, and so on, but…

I recently needed count the number of rows in an SQL query that had a Group By clause. It looked something like this: SELECT account_name FROM events WHERE created_at >= CURDATE() - INTERVAL 3 MONTH GROUP BY account_id This provides a list of account names (28 in my case), but if you try to count them using: SELECT COUNT(account_name) as…

TL;DR: If someone sees you enter your passcode on your phone and then steals your phone, they can lock you out of your Apple account, losing access to all your iCloud data, including photos. Treat your phone passcode as carefully as the secret it is. The problem I heard about "A Basic iPhone Feature Helps Criminals Steal Your Entire Digital…

I have just returned from the 2023 edition of PHPUK and, as always, found it a valuable conference to catch up with the PHP community and find out what’s happening in the ecosystem. This year, I was accepted to speak on the differences between RPC, REST and GraphQL APIs and was surprised and gratified that the room was at full…

A very big part of my work at Covie for the last year has been putting in place the processes required for to achieve SOC 2 Type II compliance. This standard by the AICPA is all about an organisation's security, availability, processing integrity, privacy and confidentiality controls and processes. It's a comprehensive set of requirements covering our product's and organisation's…
