Recently, I got an email from a reader who noted that I hadn't published anything in a little while, and he said he hopes I'm doing well. The truth is, some days I am and some days I'm not. I want to share a little bit about what's been going on, and what the future looks like. This is a pretty vulnerable post, so here's the deal. I'm going to tell you this, but it's just between you and me, okay? And there's one condition: you don't reach out to me to say "I'm so sorry!" When people share stories like this, it's often met with pitying responses. These often serve to make the sender feel better, not the recipient, and it feels bad to receive. I much prefer genuine connection from people who've had or seen similar experiences, or understand what I went through, or are facing something similar. I usually write my posts to educate, entertain, or a mixture of the two. This one is different. I'm not writing it to ask for pity or sympathy, but it's also not educational, and it probably won't be entertaining in a "this is fun to read" sense. The main thing I'm looking for here is connection, and maybe giving someone else on a similar journey something to hold onto. So here I am. I'm alive, and I'm writing this post. It's the first post I've written in over four months. That's the longest break I've taken from writing blog posts since I started writing regularly in 2022. What happened? what happened? enter: pain I've had nerve pain and tingling on-and-off since 2022. It was in my hands and forearms, and it was really sharp and really strong. If I type on a regular keyboard, this comes back with a vengeance. Instead, I started using Talon Voice for all my writing and coding, and eventually got a Keyboardio Model 100 which helps me mitigate the pain. The pain would only come on when it was triggered by certain conditions. A physical therapist eventually figured out some shoulder positions were contributing. I knew my keyboard was contributing. If I did something the wrong way, I'd be in pain for days afterwards, but if I did everything just right, I'd go months without any pain. The pain was with me when I started blogging regularly. The first posts in my weekly cadence were all written using my voice, not my hands. I committed code at work, pair programmed, wrote design docs, and was a very effective software engineer and leader. The pain was a little distracting, but it was not debilitating as long as I took care of my body. Accessibility tech saved my career, truly, and reduced my pain dramatically. I could not have gotten through the last four years of gainful employment without Talon, my keyboard, and the portable ergonomic setup I designed. I settled into a comfortable existence in my life: I had this oddball setup, it made me quirky but in a fun way. But then things got much worse. neurology, part 1 A year ago, I started to notice some other symptoms. They were tolerable and not very distressing. But since they were a change in something that was stable, and pointed to different potential causes than the presumed diagnosis, I wanted to get checked out to be cautious. I got a referral to neurology, and went to one of the best neurology departments in my area. We ran a lot of tests, and didn't find anything wrong. This was supposed to be relief, because it meant nothing was progressive: I shouldn't expect it to get worse, certainly not quickly. (Is this foreshadowing? It sure is!) It was also a little frustrating, because it meant we still didn't know why I had these weird sensations and pain. Three years in, no diagnosis. My doctor told me to follow up with her in a few months, and we'll keep monitoring this. I didn't follow up, because I was recovering from a planned surgery, and I was feeling pretty good. That didn't last. business ramps up A few months after my surgery, I left my job of 8 years and started my business! This was a milestone I was working toward for a while, and I was excited to dive in. I loaded up my calendar with chats. Work came in from one client, developing some software in an industry that is very privacy and security conscious. Other friends and acquaintances were happy to chat with me, and some promising leads came up. Some clients came in asking for coaching, too. Things looked so good and promising for me and my business. more tests At the same time my business was starting to ramp up, so were my nerve issues. The pain started to ramp up, and so did some unsettling sensations in my peripheral nerves. This time was different. Instead of something that I could manage and mitigate on my own, it would take over my life. But I didn't know that just yet. At this point in the story, it just felt annoying. I got an appointment with my neurologist, and went back in. She ordered more tests, and we discussed medication to manage the symptoms. Yet again, the tests said everything is normal, when my doctor and I could both clearly see that it was very much not normal. Meanwhile, the pain got worse. A month after that appointment, I was constantly at 6 or 7 on the pain scale[1]. I couldn't feel temperature in my hands, and my fingers were a little numb. My feet were burning most of the time. And I had so much brain fog that I wasn't sure if I could code a hello world example. I wasn't capable of working even one hour in a week. And we didn't know why, or what was happening to me. The only thing we could do was monitor symptoms more, and cover them up. And so I started medication. It helped, a little bit, maybe. I started using a TENS unit. It helped, for the time it was on. I started physical therapy. It helped, being forced to exercise. I worked with a dietitian nutritionist. It helped resolve other symptoms, improved quality of life. I landed a bigger client, and ramped up my work hours. I'd go through times when I worked too many hours, landing myself back on bed rest for a couple of days after. Six hours was too many. Three was maybe doable. My life felt like it was over, in a lot of ways. But we kept working on it, and adjusted my medication. Eventually, I felt mostly okay again. stable With the right medication, dietary changes, physical therapy, and (attempts at) relaxation, I got to what felt like a stable point. (Again with that foreshadowing!) I was able to take on more clients, and work more hours. That's where I am today, mostly. I say mostly because, well, today I'm actually in pain again. I've had the weird nerve symptom precursors on and off a lot recently. My fatigue is at the gate, held off for now but waiting to storm the keep. I'm writing this post with pain in my arms, but I'm typing, and that doesn't seem to make it worse. Neurology and I continue to be besties, working on our mutual hobby of debugging the weird things my body decides to do. I finally had some blood tests which were out of band one way, then the other way. I am having new symptoms, which gives us more leads to pull on. I'm still in pain, sometimes, but it's bearable and not constant. I am able to do more work every day than I have since the middle of last year. But it feels a little bit precarious. That's the life of having a chronic illness and chronic pain, especially when you don't have a diagnosis and you don't know the triggers. I have a really good life. Business is going well enough that I'm able to comfortably support my family. (That said: please do give me more business!) My personal life is also going well. And I'm making some beautiful poetry and music. I cherish this life. I'm drinking in every minute I can. I don't know if I have one more year of playing my saxophone, or sixty more. So I'm going to enjoy it and be in the now, and worry about tomorrow, tomorrow. what's next on the blog? It's probably clear that I'm not coming back to weekly blog posts. Or that if I do, it's not going to be something I can rely on doing for the long haul. But I'm finally well enough that I do have the urge to write again. The urge to dive deep into tech and do weird things with it, just to horrify you all. I'm honestly not sure what's next. I have a few ideas I want to work on, but my time is limited. My business is taking a lot of my energy, as are my personal life and some medical needs. I might end up writing more things like this. Essays that wind through a personal topic. Dives into things like Lyme disease tests and the ways in which they're broken. Explainers about all the different pain scales. And I might end up writing tech posts. Explain something that I learned recently. Make a silly, terrible idea come to life, and subject you to it share it with you. Expound on leadership topics and the human side of tech. But when will it happen? I really don't know. I had quietly launched a Patreon page this year, and I've shut that down, since I can't keep that up with all of *gestures at her body's shenanigans* this. A dream I had, and still have, is to be able to make a living from my creative endeavors. That dream seems like it will remain just a dream, but things can always change. * * * And yet. And yet, I'm happy. Dreams are great, but they can't hold a candle to life itself. Life's pretty rad. In the last few months, I've written more poetry than ever before in my life. Better poetry. Meaningful poetry, silly poetry, poems about booty calls and poems about grief. My music has taken on more expression and more meaning. I've been able to write instrumental pieces that authentically communicate an arc I had through trauma and recovery. Connections with people have formed, and deepened. New people have entered my life, enriching it more than I could ever have imagined. Old friends have shown me so much love and support through my hardest moments. This isn't what I thought my life would look like. It's both harder and better than I'd ever dared to wish for. If you're wondering, I think this one from Alberta Health Services is the clearest, most useful pain scale. ↩
I have some weird hobbies, and one of those is opening up the network tab on just about anything I'm using. Sometimes, I find egregious problems. Usually, this is something that can be fixed, when responsibly reported. But over time, I learned a bitter lesson: sometimes, you can't get it fixed. Tracking my package Recently, I was waiting for a time-sensitive delivery of medication. It used a courier company which focused on just delivering prescription medications. I opened up the tracking page on my computer, and saw the information I wanted: the medication would probably arrive around 6 PM. But... what if there's more? And what are they doing with my data? Can anyone else see it? So I peeked at the network tools, and was disappointed by what I saw. The first time this happened, I was surprised. By now, I expect to see this. And what I saw was every customer's address along the delivery route. I also saw how much the courier would get paid per stop, what their hourly rate was, and the driver's GPS coordinates (though these were sometimes missing). After the package was delivered, the tracking page changed and displayed a feedback form, my signature, and a picture of my porch. The JSON payload no longer included the entire route, but it included my address, and the payload from an easily guessable related endpoint did still contain the entire route. And that route? It included other recipients' ids, which can be used to find their home addresses, names, contents of the package (sometimes), a photo of their porch, and a copy of their signature. Um. This is bad, right? Resposibly disclosing the vulnerability I've actually found approximately this vulnerability in two separate couriers' tracking pages (and they're using different software). One of them was even worse for them, it included their Stripe private key, I suppose as a bug bounty for people without ethics. And each time I find it, I try to report it. And I fail. They don't let me report it. These companies don't list security contacts. The staff I can find on LinkedIn or their website don't have email addresses that I can find or guess. Mail sent to the addresses I do find listed has all bounced. I tried going through back channels. I messaged the pharmacy which was using this courier. I talked to my prescriber, who was shocked at this issue. And the next time I got a delivery, it came via UPS instead (they do not have a leaky sieve for a tracking page, but they did "lose" my prescription once). But I don't know if they just did that for me, the miscreant who looks at her network tools? Or did they switch everyone over to a different courier? Either way, at least my data was safe now, right? It was, until I started using a different pharmacy, and this one is back to using the leaky couriers again. Sigh. It's not my responsibility to fix this (and I can't) I got pretty upset about this at one point. There's a security issue! Data is being leaked, I must get this fixed! And someone told me something really wise: "it's not your responsibility to fix this, and you've done everything you can (and more than you had to)." And ultimately, she was right. I was getting myself worked up about it, but it's not my responsibility to fix. Sometimes there will be things like this that are bad, that I cannot fix, and that I have to accept. So, where do I go from here? I could probably publicly name-and-shame the couriers, but it would not do anything productive. It would not get their attention to fix it, and it wouldn't be seen by the folks who need to know (pharmacists and prescribers). So I'm not going to disclose the specific company, because the main thing it would do is risk me getting in legal trouble, for dubious benefit. I've already notified the pharmacists and prescribers that I know; it's on them, if they want to let anyone else know.
I'm working on a silly word game right now, which means I need a list of words for it. I can't rely on the system word list, since this is for a web project. I'd also like, ideally, multiple lists of words with different criteria: most common words, all words, some subsets. It's not really clear how many words there are, because what is a word[1]? And how do you find what words are in use? Or decide that something's used enough that it merits being put in a list, rather than just being a misspelling or something used once or twice? You probably don't want every mashing of keys that someone's done in there, or adjklfalkjsdfaklsd and variations are going to take up some considerable space. So that results in a lot of different word lists being available! With that in mind, here are the two best word list sources I found and some of their properties. WordNet: a while back, researchers at Princeton put together WordNet, a database of relations between words. This includes definitions and synonyms and things like that. It's no longer maintained by Princeton, but was forked and maintained with a release 1 month ago. There are libraries to load it. Wortschatz Leipzig frequency lists: A project under Leipzig University, this is a collection of word frequency lists from various sources. The English downloads page has datasets drawn from news, the web, or Wikipedia. And there are two honorable mentions, which I want to call some attention to. These are useful, but not useful for this project. /usr/share/dict/words: Unix systems come with word lists installed, which is handy for things like spellcheckers. On my system, this file contains about 480k words. This is accessible through various libraries, too. Mine does contain things like "1080", so I want something a little cleaner. It's nice to have available! Licensing isn't super clear to me, but it can be figured out and the word list could (with appropriate licensing) then be distributed with the application. Wikitionary: It's available under permissive license terms! There's a page documenting different frequency word lists, which can be used to get the top words from different contexts, like the most common words on wikipedia, in TV scripts, or in contemporary poetry! It doesn't make the cut for me since the data is prepared for human consumption rather than being machine readable. The WordNet data and Leipzig frequency lists both need to be loaded and processed, but the formats are documented and can be implemented pretty easily, especially if you have a specific subset of the data you need. I'll be using the Leipzig data most likely for my silly little word game. I might combine it with WordNet to be able to pull up definitions, but we'll see! Someday I'd like to pull some of the Wikitionary data, because it's really cool and has a lot of different frequency lists. Like the one with the 2000 most common words in contemporary English poetry. That might not make the cut for this project, but that's just crying to be used for something else. For example, I maintain that "apple tree" is a word. "Tall tree" is two: "tall" is an adjective that's used to modify "tree" which is a noun. But that's not true with "apple tree" since, "apple" isn't an adjective, it's another noun. We use "apple tree" as one singular word, and it has its own dictionary entry. I'm only slightly joking. ↩
As I do every year, it's that time to reflect on the year that's been, and talk about some of my hopes and goals for the next year! I'll be honest, this one is harder to write than last year's. It was an emotionally intense year in a lot of ways. Here's to a good 2026! Reflecting on 2025 Where last year I got sick and had time black holes from that, this year I lost time to various planned surgeries. I didn't get nearly as much done, because it was also hard to stay focused with all the attacks on trans rights happening. Without further ado, what'd I get up to? Professional I helped coaching clients land job and improve their lives at work and beyond. I started coaching informally in 2024, and in 2025 I took on some clients formally. During the year, I helped clients improve their skills, build their confidence, and land great new jobs. I also helped clients learn how to balance their work and home life, how to be more productive and focused, and how to navigate a changing industry. This was one of the most rewarding things I did all year. I hope to do more of it this coming year! If you want to explore working together, email me or schedule an intro. I solved interesting problems at work. This reflection is mostly private, because it's so intertwined with work that's confidential. I learned a lot, and also got to see team members blossom into their own leadership roles. It is really fun watching people grow over time. I took on some consulting work. I had some small engagements to consult with clients, and those were really fun. Most of the work was focused on performance-sensitive web apps and networked code, using (naturally) Rust. This is something I'll be expanding this year! I've left my day job and am spinning up my consulting business again. More on that soon, but for now, email me if you want help with software engineering (especially web app performance) or need a principal engineer to step in and provide some engineering leadership. I wrote some good blog posts. This year, my writing output dropped to about 1/3 of what it was last year. Despite the reduction, I wrote some pretty good posts that I'm really happy with! I took a break intentionally to spend some time dealing with everything going on around me, and that helped a lot. I didn't get back to consistent weekly posts, but I intend to in 2026. Personal My hernias were fixed. During previous medical adventures, some hernias were found. I go those fixed[1]! Recovering from hernia repair isn't fun, but wasn't too bad in the long run. It resolved some pain I'd had for a while, which I hadn't realized was unusual pain. (Story of my life, honestly.) Long-awaited surgery! In addition to the hernia repair, I had another planned surgery done. The recovery was long, and is still ongoing. My medical leave was 12 weeks, and I'm going to continue recovering for about the first year in various forms. This has brought me so much deep relief, I can't even put it in words. Performed a 30-minute set at West Philly Porchfest. I did a solo set in West Philly Porchfest! All the arrangements were done by me, and I performed all the parts live (well, one part used a pre-sequenced arpeggiator). I played my wind synth as my main instrument, layering parts over top of myself with a looper, and I also played the drum parts. You can watch a few of the pieces in a YouTube playlist. Wrote and recorded two pieces of original music. This was one of my goals from 2024, and I'm very proud that I got it done. The first piece of music, Anticipation, came from an exercise a music therapist had me do. I took the little vignette and expanded it into a full piece, but more importantly, the exercise gave me an approach to composition. I'd like to rerecord Anticipation sometime, since I've grown as a musician significantly across the year. My second piece I'm even happier with. It's called Little Joys, and I'm just tickled that I was able to write this. I played it on my alto sax (piped through a pedal board) and programmed the other parts using a sequencer. One of my poems was published! I've written a lot more poetry this year. One of my close friends told me that I should get one of them published to have more people read it. They thought it was a good and important poem. That gave me the confidence to submit some poems, and one of them was accepted! (The one they told me to submit was not yet accepted anywhere, but fingers crossed.) You can read my poem, "my voice", in the December issue of Lavender Review. Last year's goals Every year when I write this, I realize I got a lot done. This year was a lot, filled with way more creative output than previous years. How does it stack up against what I wanted to do last year? ❓ Once again, I wanted to keep my rights. It's a perennial goal, and I did keep my rights in the state/community I live in. I'm awarding this one a question mark since my rights were under assault, and there are now many more places I cannot safely travel to. That means it's not a full miss, but not a win either. ✅ No personal-time side projects went into production! Yet another year that I toyed with the idea and again talked myself out of it. I'm taking it off the list for 2026, since the urge wasn't really even there this time. ✅ Maintained relationships with friends and family. I've had regular, scheduled calls with some people close to me. I've visited people, supported them when they needed me, and asked for support when I needed it. ❓ I did a little consulting and coaching, but didn't explore many ways to make this (playful exploration like I do on here) my living. I'm giving this the question mark of dubiousity, since I don't think I got much information from the year toward the questions I wanted to answer. ✅ Kept my mental health strong! There were certainly some challenges. What I'm proud of most is that I recognized those challenges and made space for myself. That's why I stopped blogging regularly: I needed the space to get through things with intact mental health. ❓ Did some ridiculous fun projects with code, but not as much as I wanted. The main project was making it so I can type using my keyboard (you know, like a piano, not the thing with letters on it). I had aspired to do more, and I'm glad I let myself relax on this. ✅ Wrote some original music! ✅ Also recorded that original music! It's on my bandcamp page. I am really proud of how much I did on my goals. I might be unhappy with my slipping on if it were a "normal" year where the government isn't trying to strip my rights, but you know what? I'll take it. Especially since I prioritized my health and happiness. Hopes and goals for 2026 So, what would I like to get out of this new year, 2026? These aren't my predictions for what will happen, nor are they concrete goals. They're more of a reflection on what I'd like this coming year to be. This is what I'm dreaming 2026 will be like for me. Keep my rights (and maybe regain ground). A perennial goal, I'd like to be able to stay where I am and have access to, I don't know, doctors and bathrooms. We've held a lot of ground this year. Hopefully some of what was lost can be regained. I'm going to keep doing what I can, and that includes living my best life and being positive representation for all others who are under attack. Maintain relationships with friends and family. I want to keep up with my friends and family and continue having regular chats with those I care about. We're a social species, and we rely on each other for support. I'm going to keep being there for the people I care about when they need me, and keep accepting their help as well when I need them. Spin up my business. I'm going out on my own, and I'm going to be offering my software engineering services again. By the end of the year, this will hopefully be thrumming along to support me and my family. Publish weekly blog posts (sustainably). I'm back in the saddle! This is the first post of 2026, and they're going to hopefully keep coming regularly. To make it sustainable, I'm going to explore if Patreon is a viable option to offset some of the time it takes to make the blog worth reading. Record a short album. I have a track in progress, and I have four more track ideas planned. I accidentally started writing an EP, I think??? This year I would love to actually finish that and release it. Publish more poetry. Writing poetry this year was very meaningful, and it's deeply important to me. I want to get more of it published so that I can share it with people who will also be able to get deep importance from it. * * * That's it! Wow, the year was a lot. I've put a lot of myself in this post. If you've read this far, thank you so much for reading. If you've not read this far, then how're you reading this sentence anyway? 2025 had a lot in it. There were some very good things I am very grateful for. There were some very scary and bad things that I wish had never happened. All told, it's been a long few years jammed into one calendar year. I hope that 2026 will be a little calmer, with less of the bad. Maybe it can feel like just one year. Regardless, I'm going to hold as much joy in the world this year as I can. Please join me in that. Let's fill 2026 with as much joy as we can, and make the world shine in spite of everything. The surgeon really meshed me up! ↩
Keeping up with regular blog posts is a challenge. To do it, I've churned through a few different organizational systems. Sometimes I have to change them due to actual life circumstances changing; other times, due to the old one just wearing off[1]. Well, my life circumstances have changed again. I'm on medical leave right now recovering from surgery[2], and I have been writing less this year anyway. So it's that time again: new system, baby. This post isn't a how-to. It's not a prescription for your own organizational system. Rather, let it be an invitation to examine your own systems, and decide whether they're serving you or not. Out with the old So what am I replacing? Before this change, my system involved Obsidian and LunaTask: Obsidian for recording ideas LunaTask for keeping track of works in progress and things that have a due date When I get an intrusive thought about how I definitely need to try to make a transistor at home in my garage[3], I put that in my list of ideas. This list of ideas contains some ridiculously bad ideas, and some very good ideas. But the thing is, I can't tell which is which when I have the idea! The ideas have to sit and marinate, and then eventually one sticks in my head long enough that it turns itself into a blog post. With most of the already completed ideas removed, that file is over 150 lines long right now. LunaTask is used to get these ideas from my brain over the finish line. I have a project called "Writing" which is kanban style. Each blog post I earnestly intend to write gets added into it, and then I keep track of which ones are waiting, in progress, and completed. This is mostly useful for posts which require code to go along with them, or which require research[4]. Posts like this one that are all prose without research go pretty fast and never enter LunaTask. The thing is, this has been showing cracks. I've stopped recording blog post ideas all that much this year, because I've been stressed from "global events" (I'm a trans woman, my wife is an immigrant, etc.) and preparing for multiple surgeries. And tracking things in LunaTask is just not working for me at all, because it's disconnected from idea tracking but ends up being its own idea tracking, since I just really want to write all the posts. To be honest, I'm not 100% sure why LunaTask isn't working for me right now for this. It might just be that I need to perturb the system a bit to make a change. But no matter what the cause, it's time to change it. In with the new The new system is simpler than the old, because I'm removing a tool. I'm taking LunaTask out of my blog toolkit, and switching to tracking everything in Obsidian. The new system is going to be smaller: an ideas page in Obsidian a works-in-progress page a task tracker for recurring blog tasks I'm using a task tracking plugin in Obsidian for the recurring tasks, because there are some things I need to do on a regular schedule. If I want to publish on Monday, that means that the post needs to be written before the weekend and edited before Monday. I'm not using task tracking for actual posts because I know from personal experience that it ends up similar to my ideas page but with structure. I'm also not using Obsidian's Bases for this, because a raw text file is just the lowest friction way I've found to do what I need. A raw text file lets me move things around freely, add notes however and wherever I want, and do freeform brain dumps. Structure is a little tyrant that kills my motivation at certain phases, so bye bye structure, we're doing a coup here. * * * So far, so good with the new system. I'm sure I'll be onto another one eventually. The most important thing, I've found, is to remain mindful of whether or not the systems are working for you. Change them once they stop working. There's this phenomenon where self-help productivity books almost always help you when you adopt a new system. But the help doesn't last forever! It seems that changing your system helps in some way, perhaps from the increased awareness and mindfulness, or maybe from new dopamine. ↩ It was a planned gender affirming surgery. The recovery is long and challenging, but I'm recovering very well. I'm very thankful for the support I have from my friends, family, and community. ↩ How hard can it be? The hubris of a software engineer knows no bounds, except for that refactor you know you should do but that you think is just a little too hard. (And yes, making a transistor would be very hard, and no, I'm not going to do it. Probably. The thoughts are still here.) ↩ I have a partially written post on Lyme disease which I do intend to complete, but it's a topic that I really want to be careful around. And so it languishes. ↩
More in programming
Reading my recent computing retrospective, I realised there was a big section missing: the people in my life that made an impact and helped shape my career. Outside my immediate family, one person made an outsized contribution, and I’m fairly certain that without his influence my life would have taken a very different path. The fact that I’m still here in 2026, still writing code and being fortunate enough to have a career in something I love is testament to him. So I’d like to take a few moments to talk about my old secondary school teacher, George Dryden. Denied Back in 1995, I had a problem. I knew I wanted to study computing at university and build a career out of my passion, but there was a snag. For those unfamiliar with the UK schooling system, when you’re 15-16 you take a set of GCSE exams in a broad range of subjects. After that, you pick around 3 subjects to really focus on over a period of 2 years. These are called A Levels, and they are a big step up and are meant to prepare you for a degree-level course at university. Admission to university is also governed by these results - if you want to study computing, you’re going to need a computing A-Level, and most universities will only accept you (or “make an offer”) if you achieve a certain grade. And whilst I had taken computing at a GCSE level, my school did not offer a computing A-Level course. I instead had to settle on “Design & Technology”, which just didn’t inspire me. Instead of working on my portfolio and projects, I spent most of my time daydreaming and writing code on the Acorn Archimedes computers that were the staple of every 90s UK school. No disrespect to the teachers - they were all awesome - but it just wasn’t for me. I was miserable, and by the end of my first year, I was well on my way to failing outright with my entire future plans seemingly going up in smoke. Someone noticed That’s when George stepped in. He’d taught me computing right the way through my GCSEs, and with no A-Level course on offer, that was officially where his involvement was supposed to have ended. It didn’t. He had noticed my constant presence in the computing labs - before and after school, during lunch breaks, free “study” periods - working on some little pet project or digging into RISC OS internals. I remember him as warm, with a wicked, dry sense of humour, and a refreshingly spiky attitude to authority - I always got the sense he’d worked out for himself which rules were worth taking seriously and which ones weren’t. And he always had time for me. I spent years pestering him with questions that had nothing to do with anything on the syllabus, and he’d always find a way to answer them that actually made sense. He was just as supportive of my odd little obsessions. At one point I’d got deep into the BBS scene, which I thought was the coolest thing ever, and decided what the school really needed was an internal BBS running on its own network. So I wrote one. It was deeply cringeworthy, obviously - but George helped me put posters up around the school advertising it, and even gave it a mention in assembly one morning. I think about five people in total ever checked it out. It didn’t matter: a teacher had stood up in front of the entire school and treated my weird little project like it was worth something, and that was a hugely validating moment for me. Off the books He recognised the passion, and eventually he made a suggestion: What if I quit the Design and Technology course, and instead attempt the A-level course myself? Personally, I also suspect he was enjoying himself. There was some internal school politics behind why computing wasn’t offered at A-Level in the first place - I never knew the details - and I think the prospect of one of his students simply going out and getting the qualification anyway appealed to him on two separate levels. It would get me where I wanted to go, and it would wind up exactly the right people. It wouldn’t be easy, he warned. The school would be against it, plus it was a two-year course which I’d have to cram into one year. I’d have to do it all myself - studying, lesson planning, coursework - he couldn’t help me in an official capacity, but he said he’d advocate for me and help where he could. If I had assignments, he’d send them off to be graded and would give feedback in his own time. He’d enter me in for the exams and also gave me a set of keys to the computer lab so I could use it whenever I needed. It was the first time anybody outside my own family had really shown faith in my abilities and encouraged me to take a stand. It was a pivotal moment for me - I realised if I wanted something badly enough I would have to fight for it, but I could still make it happen. I didn’t have to take “NO” for an answer - a lesson I think I picked up from watching him as much as from anything he ever actually said to me. After a few weeks of dithering, I took the jump. I remember a few awkward meetings with the school administration but thanks to his behind-the-scenes work, I was soon following my dream. An intense year And yes, it was bloody hard work. I had to condense an entire two year course into under a year, be disciplined enough to produce my own study plan, and be critical enough of my own shortcomings that I could focus my study where it was needed. I pretty much lived and breathed it for months straight and was more-or-less a permanent fixture in the labs or school library poring over my course books. I’d make lists of questions and chat to George over lunch, and he’d provide guidance and encouragement. It was a lonely way to learn with no classmates to compare notes with, no lessons to turn up to, and right up until the end I had no real idea whether any of it was good enough - but bit by bit, it started to feel like something I could actually pull off. And sure enough, in the late spring of 1996, I sat down in an exam hall with my fellow students, the only one with an A-Level computing question paper in front of me. The final exam went by in a blur - I can only remember a few of the questions now (and a peculiar obsession with the Pascal language) - but I do remember the euphoria as the invigilator called “time’s up, pens down, close your papers NOW”. I had done it. A few nerve-wracking months later, my Mum drove me into school to pick up my results. I ripped open the envelope and saw it - I’d passed with an A grade! I literally ran up the stairs to George’s office next to the computing labs to thank him personally. I’d taken my camera into school to take a few last photos for memory’s sake and snapped this photo of him before I walked out the school gates for the last time: A different path Because of him, I managed to get into my university of choice, studying computing with a focus on networks. Because of that, I landed my first job working as a “webmaster”, and my career since has been one of the highlights of my life. All these years later, it’s a real privilege to be able to get up each morning and actively look forward to working in an industry I love. Without George stepping up for me and encouraging me to believe in myself, none of that would have happened. I wouldn’t have had the career I have, and I wouldn’t be where I am now. I met my wife when we both worked at a software company - she sat at the desk behind me - so even my home and family life can be traced back to that spring of 1996. And the A-Level itself was only half of what I took away from that year. The qualification opened the door to university, but the lesson that came with it was every bit as important: that a “no” isn’t always the end of it, and that sometimes the answer can be argued with. I’m so proud of what I managed to achieve all those years ago, and even more thankful to have had someone like George in my life to put me on the right track. Mr. Dryden I did see him again after I left. He drank in one of my local pubs - a pub I’d been going to for a good while before I was technically old enough to be in it - and I’d say hello if I spotted him in there, mostly in the months before I moved away to university. After that it was only a handful of times. For years I’d find myself scanning the room whenever I was back home and in for a pint, half expecting him to be at the bar. At some point I stopped seeing him altogether and eventually moved across the country. The trouble was I never really knew how to talk to him outside of school. He was always Mr. Dryden, or just “Sir”, I don’t think I ever once called him George to his face! I was (and still am if I’m honest) fairly socially awkward, and I never worked out how to phrase the thing I actually wanted to say: that he had changed the entire direction of my life, and I wasn’t sure he knew it. So instead I’d say hello, and ask how he was, talk about nothing much, and go back to my friends. Epilogue Sadly, 3 years ago now, I opened the latest issue of my old school alumni newsletter to read that he’d passed away. The photo at the start of this article was taken from his obituary article and I read that he’d had a long illness and had suffered from dementia at the end. I did write to him years ago by email - I don’t know if he ever got it, or was in any capacity to understand what he’d done for me, but I hope so. There’s an old saying by one of my favourite authors (Terry Pratchett) that “no one is finally dead until the ripples they cause in the world die away”. In one of his books, a character keeps the memory of his son alive by passing his name along a series of telegraph towers. It’s in that spirit that I’m writing this post - I debated it for many years as it’s very personal to me and I also have no contact with any of George’s family so I have no idea what they would make of it all. But even though it’s 30+ years ago now, I will never forget him or what he did for me - and at least now, if someone searches his name it’ll be recorded here for as long as I’m alive and running this site. Thank you, Sir. George Dryden 1942-2023
Let’s step inside the kernel and understand how it implements copy-on-write and what are its implications for the performance of user-space systems
Yesterday, I received this email as a response to You Can't Vibe Code Love. It's such a remarkable and powerful statement that I asked permission to share it here, in its entirety, with personal information redacted: Hey Jeff, Hope you and your family are doing well.
A frustrated Reddit post about being a condom between an AI and production made the rounds in our team. Here is why I think the opposite is true and what it means for how we review code, plan work and think.
And here we are three years after I wrote about the Google Pixel Fold being announced, followed now with the announcement of the iPhone Duo...(I have questions about the naming by the way). Four years ago I was talking about web primitives in the platform for the Surface Duo. My how time flies. There are CSS media features, a Viewport Segments API, a Device Posture API but Chromium based browsers are the only ones currently supporting these things. I haven't been able to find any signal yet on whether Safari will support these things in the web platform as the developer docs focus on application development. If you're interested in trying out the platform features, you can emulate the Surface Duo and Galaxy Z Fold in the developer tools. And if you're thinking, do I really have to have my website adapt to two screens? The answer is no. Adding a design to an application or dual screen makes sense if you have an experience that has two simulataneous contexts that are useful e.g. a list of email messages/inbox on one screen, an open message, email thread or email composer on the other. Here's one of my talks from 2022 if you're interested in learning more about what's available in the browser for dual screen/foldable devices. Happy building :)
