Evolving my ergonomic setup (or, my laptop with extra steps)

from ntietz.com blog - technically a blog [alt+shift+b] in programming

My computer setup attracts attention when I'm out and about. This has two effects: engineers1 ask me about it, and everyone else ignores me. These effects are not undesirable, but further testing is required. The main reason I have such an unusual setup, though, is more practical: so my arms/hands do not hurt from using my laptop. I wrote about the second iteration before, and a lot has changed since then. Now it's time to record all the previous iterations2 and then detail what's new. Prototypes 1 through 3 Prototype 1: chonky tray The first prototype is what I lovingly call the chonky tray. It was really a portable desk, with a recess routed into it so that the laptop stand could sit inside of it. This prevented that from sliding off, mostly, and gave a flush surface under it for the keyboard. This setup worked, sort of. I could use my keyboard in my armchair in our living room—but I could not use it in the armchair in my office, because it was too wide! It was also way too heavy and too large to move around the house, let alone anywhere outside the house. This first prototype really served only to ignite my desire to have something, and to show me some things that don't work. But I kept hurting myself by not using it. Prototype 2: luggable in backpack The second prototype is the one that was detailed in my previous blog post. It was motivated by this realization that I was going to visit the Recurse Center, a programming nerd enclave in NYC, and could not take my laptop with me since I had no portable way to use it without injury3. So, I made this! This one worked pretty well for me! It let me fit my whole setup in my oversized backpack, and I could easily take it out of there and use it on the go. I used it on the train ride up to NYC, inside RC's headquarters, and in coffeeshops. But it wasn't perfect. It was a bit heavy, though with the keyboard I was using, there wasn't much to do about that. Getting my laptop in and out was annoying, since I had to unscrew a...

Where I've been, and the future of this blog

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. ↩

You can't always fix it

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.

Some good English word datasets

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. ↩

Reflecting on 2025, preparing for 2026

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! ↩

A new system for organizing my writing and projects

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.

Haunt 0.4.0 released

I'm quite a bit late on this one, but Haunt version 0.4.0 was released released back in July. I haven't had much time for blogging, but I'm catching up now! This release contains a small set of improvements and bug fixes since the 0.3.0 release in 2024. About Haunt Haunt is a static site generator that uses the Guile Scheme as its configuration language. It aims to be simple, functional, and extensible. Features include: Easy blog and Atom/RSS feed generation Markdown post support Simple development server for viewing edits before publishing Purely functional build process User extensibility Notable changes Added support for HTML in Markdown documents. This was a long time coming because guile-markdown did not support it and the library was abandoned by the original maintainer. As part of my work at Spritely, we forked it, implemented the relevant portions of the CommonMark specification, and released it. Spritely's guile-commonmark fork is now considered to be the official upstream by Guix and others. A further consequence of this is that guile-lib is now a required dependency for building Haunt as we need the (htmlprag) module to parse Markdown documents with embedded HTML. html->shtml from guile-lib's (htmlprag) module is now used instead of xml->sxml in the HTML reader. It was silly of me to use xml->sxml for this purpose years ago, but at the time I wanted guile-lib to be an optional dependency. Added haunt new subcommand for creating a new site. Added default directory, template, and prefix arguments to flat-pages procedure. Added support for index metadata flag to flat pages for pretty URLs. Flat pages now receive all page metadata, not just the page title. This is a breaking change from 0.3.0. Added .scm as an additional extension for sxml-reader. make-file-extension-matcher now supports multiple extensions. Fixed emission of <script> and <style> elements. Fixed handling of no available reader in flat pages builder. Fixed unreachable error handling clause when a reader is not found for a post. Fixed default blog theme template missing an <html> tag. Fixed overloaded -h option in haunt serve. Deprecated post in Skribe reader in favor of document. Download Haunt 0.4.0 is already available in Guix: guix pull guix install haunt See the Haunt project page for information on how to build from source. Thank you to Camilo Rodrigues, Noé Lopez, jgart, Jakob L. Kreuze, and Daniel Meißner for their contributions to this release! Happy haunting!

I Bought A Scanner (No, Really This Time)

This is a transcript from a talk I gave at the German Perl Workshop earlier this year. If you'd prefer to watch the video recording, you can find it here. I have lots of photographic projects on the go. Lots of these being on film, as some of these I started shooting a long time ago. I don’t have any particular loyalty or attraction to film, it’s just that I started shooting many of these projects before affordable medium format digital was available. Since I mostly shoot medium/large format film I never really jumped to digital until recently, so film has continued to feature heavily in my workflow. That said, it’s a pain in the arse to shoot film now given the spiraling costs, limited availability, and issues around traveling with it: modern airport CT scanners, being rolled out across many airports, are much more convenient but will fog film. Asking for a hand inspection often comes down to arbitrary timing - how busy the security is, how experienced the operator is, or if you’re lucky/unlucky. I’ve had film forced to be scanned (and fogged) and politely argued with security on more than one occasion. I don’t want to deal with that so don’t travel with film anymore, thus I am shooting less of it and have mostly moved to digital. I still have a tonne of film I need to scan and process however. Here’s just some of the binders and files of film. I don’t plan to scan all of this, but I do plan to scan the ones I need to. Probably in the region of a couple of thousand frames. I want to scan to the highest possible quality (within reason) for archiving, book projects, and large prints. If you’re wondering how large I print, it can be up to 160x60cm panoramics for selling. This is restricted by the size of my printer (that’s another story). Three Years Ago Three years ago I almost bought a scanner. I ended up blogging about it and the post got a bit of traction on Hacker News (HN). I’m never quite sure which posts I submit will pique the interest of the users. I’ll spend months chipping away at a draft and when I post it it tanks. Or I’ll cobble something together in twenty minutes, like the linked one above, and it gets 440 points and over 300 comments… The thread had some useful suggestions and some not so useful ones, the not so useful ones being effectively “buy an Epson”: I’ve had one for fifteen years and it’s not good enough for large prints or archiving. It’s passable for web stuff and smaller prints, but for my recent use cases? Not even close. Ten years ago I had negatives scanned with a high resolution scanner for the first time and recently, wanting to scan my archives for various projects, I decided I should invest in one of those scanners. The Original Plan The plan, back in 2023, was simple: Buy scanner (at significantly reduced rate) Scan all my film Sell scanner Profit! And I mean profit - the scanner that I almost bought was being offered to me at about 2/3rd of the price they usually sell. And they’re becoming harder to find in working order so the prices are going up. Or profit in not having to pay > 25.- CHF per frame to have someone else do this. You can see the pricing from The Film Lab. You can read the original blog post to find out more about the scanner in question, so I won’t repeat it here. Other than the parts being relevant to the rest of this post, namely that the scanner was showing hard and soft problems. The software that drives the scanner was last updated in 2012, it’s proprietary and closed source, requiring 32bit architecture and no third party drivers or software exist. So you are stuck using old software/computers to run it. Or maybe you could use emulation / virtualisation? The problem there is that the interface is firewire, or SCSI on the even older models, and firewire is known to be problematic on these scanners as the controllers start to go bad after a decade of continued use. That’s a risk, and the scanner was very much EOL as the firewire controller was dying: both ports were bad that suggests controller, not ports. The scanner would have been €5,000 to purchase and then €3,000 (ish) to repair. Or, as HN suggested - just open it up and use a soldering iron. I’m not going to drop 5k on something and then start poking it with a soldering iron. I’ll pass on that thanks. Camera Scanning In the meantime I’ve been camera scanning, which you can read about in another blog post. But how does that compare cost wise? It’s expensive because you’ll need a high resolution camera, a macro lens, copy stand, negative carrier/holder, and quality light source. You’ll look to spend anything from three to five thousand Euros on everything. Camera scanning does actually work well, in that it’s close to a high resolution dedicated scanner. But you have to setup the entire thing every time you want to use it, including ensuring everything is straight and parallel. It also suffers from the same weakness as most other scanning methods. What do you think that is? Film Flatness Or lack thereof: Film is rarely flat, especially so with 35mm. These are pretty mild examples of curl. It tends to be flatter in the larger formats but then you get into flatness issues due to it sagging. The smallest difference in the film plane can cause major issues in sharpness due to focus fall off (film scanning is essentially macro photography). Any workflow or solution that does not take this into account is significantly compromised. And the workflow is only as good as its weakest part. This is the biggest problem in scanning film - all other considerations are more than adequate these days: resolution, dynamic range, etc. However, most negative carriers don’t keep the film perfectly flat. This has always been a problem - this is from a book called “Edge of Darkness” which is about traditional analog photography and printing, and summarises the problems of negative carriers thusly: “if you use a glassless negative carrier, you might as well just buy the cheapest enlarging lens you can find. You are simply throwing away the money and sharpness you paid for it in your enlarging lens, and also in your fine camera and the expensive lenses you bought for it… No film will lie flat in a glassless carrier. That’s right, none… There is no avoiding this issue. Use glass.” So you have to use (anti-newton ring) glass, which introduces other issues - you’ve now got extra glass in the transmission path, and dust (which isn’t a massive problem, but a pain nonetheless). You could use drum scanning, which is absurdly impractical from a cost and operating point of view. Or you could use a Flextight, the scanner I almost bought three years ago. Interim Solution I stuck with camera scanning, but wasn’t happy though, because of film flatness and the setup faff. So of course I started looking for another scanner. I was idly browsing near the end of 2025 and came across this one. It’s exactly the same spec as the one I tried three years ago, except SCSI not Firewire so less prone to failure. It just predates Hasselblad buying Imacon (so is pre the rebranding, etc). It was in Switzerland so I could inspect and pick it up. It was also significantly cheaper than the previous one I had looked at, so worth a punt even if I needed to take a soldering iron to it. We went to St Gallen for a weekend and I picked it up. Here’s the software interface back in my studio. Look at that marvelous interface! None of that liquid glass bollocks. The first scans were promising, but I had the sense things needed some TLC. The first thing was calibrating the focus, which the software can do in combination with a focus slide. I was lucky that the focus slide was included with the scanner and I’m not sure what I would have done otherwise. Probably paid a fortune for a replacement? Possibly a lot of manual trial and error with the software? After doing that I scanned images of the 1951 USAF resolution test chart (taken on ultra high resolution 35mm film): That’s what the resulting scan looked like. Notice that it’s sharp from edge to edge, corner to corner. At 100% crop we can resolve around 110 to 123 line pairs per mm, which equates to about 5,600 to 6,300 DPI. This is beyond the limit of most 35mm lenses, but importantly - exactly to spec for this scanner. So I was happy the focus was calibrated. If you’re curious this is the same target with the camera scanning setup. It’s close, but we’ve got another variable in the workflow, several even, and that impacts the results. It’s not as sharp, and the extra glass in the transmission path causes aberrations. Another thing that needed attention was the power supply. The seller mentioned that “sometimes it takes five minutes to warm up”. Sometimes it was more than five minutes, and the power supply would click click click away. So that needed fixing and it was easy enough to find a compatible new replacement, however it cost 200 Euros. Expensive! The third problem I noticed was that some of the scans were coming out stretched. Often about 10% too wide/long, sometimes more than that. My panoramics looked panoooooooramic. I did some research and someone suggested this might be a “buffering issue”, which I thought was nonsense. Doing some testing I heard slipping sounds when the scanner was pulling the film into the body. After more research I stumbled on a post that suggested the belts need replacing. I opened the scanner up, and sure enough: A ha! You can’t quite see that the one on the back is even worse. I replaced those with compatible belts: 535 synchroflex t 2.5/245. Problem solved. The fourth problem was that the film holders were old and/or had been mishandled. They were falling apart and held together with electrical tape or glue, which didn’t seem optimal. Replacements cost 350 Euros in total for the four I needed. They’re now available cheaper from China, since the patents have expired. Or, you know, China. They used to cost about 200 Euros each from Hasselblad. The fifth problem, which is a potential one and hasn’t manifested yet, is that the lamps may eventually need replacing. I picked up a couple for 25 Euros. That seemed like a reasonable thing to do while they’re still available. Success? Let’s add up the costs of acquiring this scanner and renovating it: Scanner: 1,750.- CHF Power Supply: 175.- CHF Belts: 25.- CHF Film Holders: 350.- CHF Lamps: 25.- CHF Total: 2,325.- CHF (c. 2,500 EUR) In the last year (since acquiring the scanner) I have scanned: c. 250 panoramics frames (~ 6,000 CHF) c. 2,500 medium format frames (~ 80,000 CHF) c. 200 large format frames (~ 9,000 CHF) The figures in parentheses are what it would have cost me to have that number of frames scanned by a third party. That is, er, quite a saving. Also quite a lucrative business model perhaps? I think I can argue the cost of the scanner was a very good investment, and I haven’t finished using it yet. Even if it were to stop working tomorrow, it has already paid for itself many times over. Could it stop working tomorrow? Yes, because of other issues that will be harder to solve. The Bigger Issue(s)? A Power Mac G4 (discontinued in 2004). This came with the scanner, the necessary hardware and software to drive it, and is almost certainly living on borrowed time. Spinning metal is never good in the long-term. I’ll maybe purchase a backup soon, as these can still be found for a couple of hundred Euros. The key thing though, is that this very expensive, very high quality scanner, will at some point be rendered useless by the upgrade treadmill because the software required to run it will be increasingly difficult to run. A scanner that is still used by businesses, educational institutions, and individuals like me. A scanner that originally cost tens of thousands of Euros less than a decade ago. The upgrade treadmill is constantly whirring away. This is from the top of the Seattle Space Needle. “Do not upgrade anything on computer”. Clearly that notice speaks of someone being bitten by an upgrade at some point. I wonder is anyone else feeling the fatigue? Security updates, sure I can understand. But feature creep and trivialities? No! What tangible benefits have the last ten, fifteen, or even twenty years of OS updates brought? Other than security, and compatibility with newer hardware? New hardware is great, really, but by association forced deprecation of older hardware. No! It feels like the upgrade treadmill gets faster and steeper every year. Add to that subscription lock-in and dead endpoints: “I couldn’t vacuum my house because an SSL cert had expired” is what someone told me earlier this year. Fortunately this person is a software engineer so ended up man-in-the-middling the network traffic to get the vacuum cleaner to work again (no SSL-pinning it seems). “GoPro is announcing the end of life of the GoPro Quik app for macOS, effective at the end of 2024”. They discontinued the former in favour of their mobile app, which requires an account, login, subscription, and so on. I just want to transfer the videos from the hardware, I don’t need any of this crap (I don’t need any of that crap, it turns out GoPro haven’t locked the device down enough to prevent using third party apps to access the files. Yet). And, of course, software has to be in everything. These days the scanner would/could have an embedded Raspberry PI? Just a keyboard and mouse input, monitor and USB output would reduce the surface area, connectivity issues, and software dependency. Or software is never done? Because: externalities. I guess software is “done” when it’s no longer supported? Marciano Planque has a good piece on this: When hardware products reach end-of-life (EOL), companies should be forced to open-source the software. I think that’s a fair thing to say. I suspect Hasselblad/Imacon never open-sourced the software due to licensing issues. Or they just lost the source. Or they just don’t care, I don’t know. Maybe some combination of the three. And, inevitably, discontinued hardware like this scanner. Or, that is to say, discontinued parts? What about regulation changes? The panoramics I shoot are with a camera that was discontinued in 2004 because EU regulation banned lead solder in circuit boards. The company decided redesigning the parts wasn’t worth it. Old hardware has new exciting ways to fail. As time goes on components will fail or loosen - components that were expected to last decades. Then that results in tribal knowledge, or worse link rot and QR code rot. A lot of this stuff is hidden in walled gardens. There’s a Facebook Imacon group, for example. Why in the ever-loving fuck is a group for technical people, by technical people, on Facebook? Then there’s misleading AI. “My flextight scans are coming out stretched, what might the problem be?” LLM’s have gobbled up all the right information, and all the wrong information. Or information that is massively out of date. Nowhere in the suggestions here does it mention the belts might need replacing, which, according to my own research, is the most common reason these days. Legacy Software A decade ago I wrote an essay that also hit the front page of HN: All Software is Legacy. I think it is still relevant today, some parts not so much given we are now in The Age of Prompt, but mostly it’s still true. Nicholas always said “legacy software is the ugly stuff that makes you money”, which I think is true. But now it’s the stuff that surrounds us, like when I want to withdraw cash (guess what software most cash machines are still running?). Or when I want to take a train - when I gave this talk in Germany I had to get from the airport to the city centre. The ticket machines were disabled with a sign saying “no longer in use, download the app”. Then register. Then buy the ticket. I just want to give you money. Or when I wanted to pay for parking while stopping off at some random town in the UK - the same situation as with the ticket machines. “Download the app, register, pay”. Fuck that, I went and parked somewhere else. I just want to park, I don’t want to fight with software. Or if I want to hire a bike (not pictured: the half dozen apps on my phone to hire a bike). And when I want to buy stuff from a shop… One of the self-checkouts crashed recently in the coop, rebooting into a version of SUSE Linux from well over a decade ago. We’re collectively creating more and more of this everyday, letting it out into the world where it becomes a future liability for someone or the death knell for something. A pile of bikes, an unplugged ticket machine, a top of the line but no longer driveable scanner.

Attention is all you have

The Tetris effect is one of psychology’s most easy to reproduce experiments. Simply spend a bit of time playing the eponymous game every day for a few weeks. After a little while, you’ll start recognizing familiar Tetromino shapes in clouds, buildings, and everyday objects. You might even see them appear before your eyes when you start falling asleep. Tom Tang Attention hijacking There’s one lesson the Tetris effect teaches us: whatever you focus on long enough will end up shaping your thoughts. This can be a good thing since it’s how we learn new skills and discover new ideas. Sadly, less and less of our attention is focused intentionally. Instead of picking what we want to see we let other people decide what is supposed to be good for us. Do you want to watch a video? YouTube knows you like cooking and art streams. But why not also recommend a few clips about the stock market bubble, global warming, and the war in Iran. Doomscrolling will make you stay longer and click on a few more ads. Do you want to listen to music? Just open a Spotify playlist and let the algorithm figure out what you like. Please ignore the AI slop they will insert in between real songs to avoid paying royalties to real artists. Do you want to know how your colleagues are doing? Too bad, LinkedIn will bury any relevant career news between the opinion of complete strangers. It is surely just a coincidence that those strangers happen to be shilling whatever Microsoft is invested in at the moment. Do you want the opinion of strangers on a product? Well those Redditors you wanted to ask are probably just a bunch of LLMs talking to a bunch of Russian trolls now. I hope you didn’t value their opinion too much. If, like me and most people, you spend the major part of your day focused on your device, there’s no doubt it’s affecting you. And when you let someone else dictate what appears on your screen, it’s the same as giving them the key to your brain. New York Said Back to an intentional internet The internet wasn’t always like that. Before recommendation algorithms where a thing, you had to decide what you would be doing on the computer. You didn’t really have one big app that you could open and order it to entertain you. Instead, you had a few dozen of bookmarks to websites, each with a specific idea in mind. A site for video game news, that one website with lots of tutorials, a blog about anime that didn’t update often enough, a wiki about a TV show from the 90s… Of course awful things existed on the web. We had Encyclopedia Dramatica and Rotten.com, but you actually had to put the effort to go there if you wanted. Nobody was going to put pictures of dead kids and far-right propaganda as a suggestion after a pancake recipe or a cat video. The good thing is that this intentional internet is still around. It has just been a bit buried below the corporate web, but it’s not very hard to find. After all you’re on this blog, so you probably already have a good idea about it. The main difference between this time and now is you. When you want to get back to reading blogs, RSS feeds, and finish that tutorial instead of doomscrolling shorts, you have to get used to a slower internet. One where content is not infinite and doesn’t get updated every click. But like every habit, the only thing you have to do is to keep at it. And if you pay enough attention to it, something will click in your brain.
