Building a photography website

from Darek Kay [alt+shift+b] in programming

Last year, I started a photography hobby. Soon after, I've created a place where I can share some of my work, without any attention-driven algorithms dictating the terms. Here's a technical write-up of my journey. Table of contents: Motivation Inspiration Design Implementation Content management Loading performance Navigation RSS Accessibility Pipeline Preparation Metadata update Content update Further steps Motivation Why should one build a photography website in the first place? Similar to this blog, I want to reduce my dependency on social media and third-party services. Even if I ignored Instagram's privacy issues and dark patterns, the fact they can delete my account at a whim is unacceptable. In fact, they shadow-banned my first Instagram account because of "suspicious activity". Pixelfed, a federated photo sharing platform, solves many issues of Big Tech. However, I can't guarantee the instance I chose to stand the test of time. Glass has potential, but there are some issues like no way to provide image alt descriptions. Instead of relying on third-party providers alone, I practice POSSE: I publish photos on my own site and syndicate them to my Pixelfed, Glass and Instagram accounts. This approach brings some further advantages: Anyone can access my photos, without the need for an account. People can subscribe via RSS to view my latest photos, without an algorithm-driven feed. I can use a custom, personalized design. I can update my photos, e.g. make changes after getting more experienced with RAW development and photo editing. I can use any aspect ratio. Instagram will often crop the image preview despite choosing "original size" on upload. I own my content. Inspiration Most photography websites are from professional artists who provide a showcase for potential clients. I was looking for a more personal look and feel. Fortunately, some fellow software developers share a photography hobby: Nicolas Hoizey (my favorite site!), Moritz Petersen,...

Grab browser links and titles in one click

When I copy a browser tab URL, I often want to also keep the title. Sometimes I want to use the link as rich text (e.g., when pasting the link into OneNote or Jira). Sometimes I prefer a Markdown link. There are browser extensions to achieve this task, but I don't want to introduce potential security issues. Instead, I've written a bookmarklet based on this example extension. To use it, drag the following link onto your browser bookmarks bar: Copy Tab When you click the bookmark(let), the current page including its title will be copied into your clipboard. You don't even have to choose the output format: the link is copied both as rich text and plain text (Markdown). This works because it's possible to write multiple values into the clipboard with different content types. Here's the source code: function escapeHTML(str) { return String(str) .replace(/&/g, "&amp;") .replace(/"/g, "&quot;") .replace(/'/g, "&#39;") .replace(/</g, "&lt;") .replace(/>/g, "&gt;"); } function copyToClipboard({ url, title }) { function onCopy(event) { document.removeEventListener("copy", onCopy, true); // hide the event from the page to prevent tampering event.stopImmediatePropagation(); event.preventDefault(); const linkAsMarkdown = `[${title}](${url})`; event.clipboardData.setData("text/plain", linkAsMarkdown); const linkAsHtml = `<a href="${escapeHTML(url)}">${title}</a>` event.clipboardData.setData("text/html", linkAsHtml); } document.addEventListener("copy", onCopy, true); document.execCommand("copy"); } copyToClipboard({ url: window.location.toString(), title: document.title });

A guide to bookmarklets

I'm a frequent user of bookmarklets. As I'm sharing some of them on my blog, I wrote this post to explain what bookmarklets are and how to use them. In short, a bookmarklet is a browser bookmark containing JavaScript code. Clicking the bookmark executes the script in the context of the current web page, allowing users to perform tasks such as modifying the appearance of a webpage or extracting information. Bookmarklets are a simpler, more lightweight alternative to browser extensions, Chrome snippets, and userscripts. How to add a bookmarklet? Here's an example to display a browser dialog with the title of the current web page: Display page title You can click the link to see what it does. To run this script on other websites, we have to save it as a bookmarklet. My preferred way is to drag the link onto the bookmarks toolbar: A link on a web page is dragged and dropped onto a browser bookmark bar. A bookmark creation dialog appears. The prompt is confirmed and closed. The created bookmarklet is clicked. The current web page title is displayed in a browser dialog. Another way is to right-click the link to open its context menu: In Firefox, you can then select "Bookmark Link…". Other browsers make it a little more difficult: select "Copy Link (Address)", manually create a new bookmark, and then paste the copied URL as the link target. Once created, you can click the bookmark(let) on any web page to display its title. Scroll further down to see more useful use cases. How to write a bookmarklet? Let's start with the code for the previous bookmarklet example: window.alert(document.title) To turn that script into a bookmarklet, we have to put javascript: in front of it: javascript:window.alert(document.title) To keep our code self-contained, we should wrap it with an IIFE (immediately invoked function expression): javascript:(() => { window.alert(document.title) })() Finally, you might have to URL-encode your bookmarklet if you get issues with special characters: javascript:%28%28%29%20%3D%3E%20%7B%0A%20%20window.alert%28document.title%29%0A%7D%29%28%29 Useful bookmarklets Here are some bookmarklets I've created: Debugger — Starts the browser DevTools debugger after 3 seconds, useful for debugging dynamic content changes. Log Focus Changes — Logs DOM elements when the focus changes. Design Mode — Makes the web page content-editable (toggle).

Prevent data loss on page refresh

It can be frustrating to fill out a web form, only to accidentally refresh the page (or click "back") and lose all the hard work. In this blog post, I present a method to retain form data when the page is reloaded, which improves the user experience. Browser behavior Most browsers provide an autofill feature. In the example form below, enter anything into the input field. Then, try out the following: Click the "Example link" and use the "back" functionality of your browser. Reload the page. Query Example link Depending on your browser, the input value might be restored: Browser Reload Back Firefox 130 Yes Yes Chrome 129 No Yes Safari 18 No Yes How does it work? I was surprised to learn that this autofill behavior is controlled via the autocomplete, that is mostly used for value autocompletion from past web forms. However, if we disable the autocompletion, the autofill feature will be disabled as well: <input autocomplete="false" /> To learn more about the behavior, read the full spec on persisted history entry state. Preserving application state Even with autofill, no browser will restore dynamic changes previously triggered by the user. In the following example, the user has to always press the "Search" button to view the results: This is an interactive example. Please enable JavaScript to use it. Query Search ... const inputElementNative = document.querySelector("#example-search-input"); const outputElementNative = document.querySelector("#example-search-output"); const performSearch_exampleSearch = (outputElement) => { outputElement.innerText = ""; const introText = document.createTextNode("Open the result for "); outputElement.appendChild(introText); const link = document.createElement("a"); link.href = "https://example.com"; link.innerText = inputElementNative.value || "no text"; outputElement.appendChild(link); }; document.querySelector("#example-search-form").addEventListener("submit", (event) => { event.preventDefault(); performSearch_exampleSearch(outputElementNative); }, ); If the web page changes its content after user interaction, it might be a good idea to restore the UI state after the page has been refreshed. For example, it's useful to restore previous search results for an on-site search. Note that Chrome will fire a change event on inputs, but this is considered a bug as the respective spec has been updated. Storing form values As the form value might be lost on reload, we need to store it temporarily. Some common places to store data include local storage, session storage, cookies, query parameters or hash. They all come with drawbacks for our use case, though. Instead, I suggest using the browser history state, which has several advantages: We get data separation between multiple browser tabs with no additional effort. The data is automatically cleaned up when the browser tab is closed. We don't pollute the URL and prevent page reloads. Let's store the search input value as query: document.querySelector("form").addEventListener("submit", (event) => { event.preventDefault(); const inputElement = document.querySelector("input"); history.replaceState({ query: inputElement.value }, ""); performSearch(); }); This example uses the submit event to store the data, which fits our "search" use case. In a regular form, using the input change event might be a better trigger to store form values. Using replaceState over pushState will ensure that no unnecessary history entry is created. Uncaught TypeError: Failed to execute 'replaceState' on 'History': 2 arguments required, but only 1 present. Restoring form values My first approach to restore form values was to listen to the pageshow event. Once it's fired, we can access the page load type from window.performance: window.addEventListener("pageshow", () => { const type = window.performance.getEntriesByType("navigation")[0].type; const query = history.state?.query; if (query && (type === "back_forward" || type === "reload")) { document.querySelector("#my-input").value = query; performSearch(); } }); I will keep the solution here in case someone needs it, but usually it is unnecessary to check the page load type. Because the history state is only set after the search form has been submitted, we can check the state directly: const query = history.state?.query; if (query) { document.querySelector("#my-input").value = query; performSearch(); } Demo Here's an example combining both techniques to store and restore the input value: This is an interactive example. Please enable JavaScript to use it. Query Search ... const inputElementCustom = document.querySelector("#example-preserve-input"); const outputElementCustom = document.querySelector("#example-preserve-output"); const performSearch_examplePreserve = (outputElement) => { outputElement.innerText = ""; const introText = document.createTextNode("Open the result for "); outputElement.appendChild(introText); const link = document.createElement("a"); link.href = "https://example.com"; link.innerText = inputElementCustom.value || "no text"; outputElement.appendChild(link); }; document.querySelector("#example-preserve-form").addEventListener("submit", (event) => { event.preventDefault(); performSearch_examplePreserve(outputElementCustom); history.replaceState({ query: inputElementCustom.value }, ""); }); const historyQuery = history.state?.query; if (historyQuery) { document.querySelector("#example-preserve-input").value = historyQuery; performSearch_examplePreserve(outputElementCustom); } Conclusion Preserving form data on page refresh is a small but impactful way to improve user satisfaction. The default browser autofill feature handles only basic use cases, so ideally we should maintain the form state ourselves. In this blog post, I've explained how to use the browser history state to temporarily store and retrieve form values.

Web push notifications: issues and limitations

In this post, I will summarize some problems and constraints that I've encountered with the Notifications and Push web APIs. Notification settings on macOS Someone who's definitely not me wasted half an hour wondering why triggered notifications would not appear. On macOS, make sure to enable system notifications for your browsers. Open "System Settings" → "Notifications". For each browser, select "Allow notifications" and set the appearance to "Alerts": Onchange listener not called Web APIs offer a way to subscribe to change events. This is especially useful in React: navigator.permissions .query({ name: "push", userVisibleOnly: true }) .then((status) => { status.onchange = function () { // synchronize permission status with local state setNotificationPermission(this.state); }; }); Whenever the notification permission changes (either through our application logic or via browser controls), we can synchronize the UI in real-time according to the current permission value (prompt, denied or granted). However, due to a Firefox bug, the event listener callback is never called. This means that we can't react to permission changes via browser controls in Firefox. That's especially unfortunate when combined with push messages, where we want to subscribe the user once they grant the notification permission. One workaround is to check at page load if the notification permission is granted with no valid subscription and resubscribe the user. Notification image not supported Browser notifications support an optional image property. This property is marked as "experimental", so it's not surprising that some browsers (Firefox, Safari) don't support it. There is an open feature request to add support in Firefox, but it has been open since 2019. VAPID contact information required When sending a push message, we have to provide VAPID parameters (e.g. the public and private key). According to the specification, the sub property (contact email or link) is optional: If the application server wishes to provide, the JWT MAY include a "sub" (Subject) claim. Despite this specification, the Mozilla push message server will return an error if the subject is missing: 401 Unauthorized for (...) and subscription https://updates.push.services.mozilla.com/wpush/v2/… You might not encounter this issue when using the popular web-push npm package, as its API encourages you to provide the subject as the first parameter: webpush.setVapidDetails("[email protected]", publicKey, privateKey); However, in the webpush-java library, you need to set the subject explicitly: builder.subject("[email protected]"); There is an open issue with more information about this problem. Microsoft Edge pitfalls Microsoft introduced adaptive notification requests in the Edge browser. It is a crowdsourced score system, which may auto-accept or auto-reject notification requests. The behavior can be changed in the Edge notification settings. Additionally, on a business or school device, those settings might be fixed, displaying the following tooltip: This setting is managed by your organization.

Website themes with uBlock Origin

Browser extensions like Stylish, Stylus or Tampermonkey make it possible to create custom website themes/skins. At the same time, I try to lower the number of add-ons that I use, mostly due to security and performance reasons. Interestingly, the uBlock Origin ad blocker can achieve similar results. We can use the style action operator to adjust the CSS of any website. Let's change the header/footer background color on this blog: darekkay.com##.inverted:style(background-color: #2e2e2a !important) With this technique, we can create custom website themes. Here's my dark mode skin for Hacker News: news.ycombinator.com##body:style(color: #CCCCCC !important; background-color: #1A1A1A !important; ) news.ycombinator.com##table:style(background-color: #2B2B2B !important; ) news.ycombinator.com##input:style(background-color: #DFDFDF !important; ) news.ycombinator.com##table, tr, td, .pagetop, .score:style(color: #CCCCCC !important; ) news.ycombinator.com##td:style(border: 1px solid #2B2B2B !important; background-color: #2B2B2B !important; ) news.ycombinator.com##b:style(color: inherit !important; ) news.ycombinator.com##a, .c00:style(color: #eee !important; ) news.ycombinator.com##.c00 a:style(color: rgb(49, 140, 212) !important; ) news.ycombinator.com##.comhead, .subtext:style(color: #828282 !important; ) news.ycombinator.com##.comhead > a, .subtext > a:style(color: orange !important; ) news.ycombinator.com##.comhead font:style(color: #5a5a5a !important ) news.ycombinator.com##.c5a, .c88, .c9c:style(color: #999 !important; ) news.ycombinator.com##input:style(color: black !important; ) news.ycombinator.com##textarea:style(background-color: #E0E0E0 !important; border-left: 12px solid #CCCCCC !important; ) news.ycombinator.com##font[color="#000000"]:style(color: #a3b72c !important; ) Bonus tip: to synchronize your styles across all devices, consider hosting your rules on GitHub. You can click the "Raw" button and provide the URL as a custom filter list to uBlock Origin. Check out my styling rules and their raw version.

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.
