Git's log and diff commands are useful for inspecting your repository changes. Both commands accept ranges of commits in different formats, which can be confusing. In this post, I will shed some light on the differences between a b, a..b and a...b commit ranges. Check out the repository that I will be using as an example. This is part 2 of my Git explained series. Part 1: Rewriting history Part 2: Commit ranges git log The git log command lists all commits that are reachable from a certain commit. git log feature You can also specify multiple commits separated by a space, which will list all commits that are reachable from any of them: git log main feature You might want to exclude certain commits from git log. The following commands are equivalent and will list all commits that are reachable from feature but not from main: git log main..feature git log ^main feature git log feature --not main Another special notation is the triple dot, which excludes the common ancestor of two...

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 });

Open Graph images: Format compatibility across platforms

While redesigning my photography website, I've looked into the Open Graph (OG) images, which are displayed when sharing a link on social media or messaging apps. Here's an example from WhatsApp: For each photo that I publish, I create a WebP thumbnail for the gallery. I wanted to use those as OG images, but the WebP support was lacking, so I've been creating an additional JPG variant just for Open Graph. I was interested in seeing how things have changed in the last 2.5 years. I've tested the following platforms: WhatsApp, Telegram, Signal, Discord, Slack, Teams, Facebook, LinkedIn, Xing, Bluesky, Threads and Phanpy (Mastodon). Here are the results: All providers support JPEG and PNG. All providers except Teams and Xing support WebP. No provider except Facebook supports AVIF. WhatsApp displays the AVIF image, but the colors are broken. "X, formerly Twitter" didn't display OG images for my test pages at all. I don't care about that platform, so I didn't bother to further investigate. Those results confirmed that I could now use WebP Open Graph images without creating an additional JPG file.

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("hello@example.com", publicKey, privateKey); However, in the webpush-java library, you need to set the subject explicitly: builder.subject("hello@example.com"); 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.

Adding auto-generated cover images to EPUBs downloaded from AO3

I was chatting with a friend recently, and she mentioned an annoyance when reading fanfiction on her iPad. She downloads fic from AO3 as EPUB files, and reads it in the Kindle app – but the files don’t have a cover image, and so the preview thumbnails aren’t very readable: She’s downloaded several hundred stories, and these thumbnails make it difficult to find things in the app’s “collections” view. This felt like a solvable problem. There are tools to add cover images to EPUB files, if you already have the image. The EPUB file embeds some key metadata, like the title and author. What if you had a tool that could extract that metadata, auto-generate an image, and use it as the cover? So I built that. It’s a small site where you upload EPUB files you’ve downloaded from AO3, the site generates a cover image based on the metadata, and it gives you an updated EPUB to download. The new covers show the title and author in large text on a coloured background, so they’re much easier to browse in the Kindle app: If you’d find this helpful, you can use it at alexwlchan.net/my-tools/add-cover-to-ao3-epubs/ Otherwise, I’m going to explain how it works, and what I learnt from building it. There are three steps to this process: Open the existing EPUB to get the title and author Generate an image based on that metadata Modify the EPUB to insert the new cover image Let’s go through them in turn. Open the existing EPUB I’ve not worked with EPUB before, and I don’t know much about it. My first instinct was to look for Python EPUB libraries on PyPI, but there was nothing appealing. The results were either very specific tools (convert EPUB to/from format X) or very unmaintained (the top result was last updated in April 2014). I decied to try writing my own code to manipulate EPUBs, rather than using somebody else’s library. I had a vague memory that EPUB files are zips, so I changed the extension from .epub to .zip and tried unzipping one – and it turns out that yes, it is a zip file, and the internal structure is fairly simple. I found a file called content.opf which contains metadata as XML, including the title and author I’m looking for: <?xml version='1.0' encoding='utf-8'?> <package xmlns="http://www.idpf.org/2007/opf" version="2.0" unique-identifier="uuid_id"> <metadata xmlns:opf="http://www.idpf.org/2007/opf" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:dcterms="http://purl.org/dc/terms/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:calibre="http://calibre.kovidgoyal.net/2009/metadata"> <dc:title>Operation Cameo</dc:title> <meta name="calibre:timestamp" content="2025-01-25T18:01:43.253715+00:00"/> <dc:language>en</dc:language> <dc:creator opf:file-as="alexwlchan" opf:role="aut">alexwlchan</dc:creator> <dc:identifier id="uuid_id" opf:scheme="uuid">13385d97-35a1-4e72-830b-9757916d38a7</dc:identifier> <meta name="calibre:title_sort" content="operation cameo"/> <dc:description><p>Some unusual orders arrive at Operation Mincemeat HQ.</p></dc:description> <dc:publisher>Archive of Our Own</dc:publisher> <dc:subject>Fanworks</dc:subject> <dc:subject>General Audiences</dc:subject> <dc:subject>Operation Mincemeat: A New Musical - SpitLip</dc:subject> <dc:subject>No Archive Warnings Apply</dc:subject> <dc:date>2023-12-14T00:00:00+00:00</dc:date> </metadata> … That dc: prefix was instantly familiar from my time working at Wellcome Collection – this is Dublin Core, a standard set of metadata fields used to describe books and other objects. I’m unsurprised to see it in an EPUB; this is exactly how I’d expect it to be used. I found an article that explains the structure of an EPUB file, which told me that I can find the content.opf file by looking at the root-path element inside the mandatory META-INF/container.xml file which is every EPUB. I wrote some code to find the content.opf file, then a few XPath expressions to extract the key fields, and I had the metadata I needed. Generate a cover image I sketched a simple cover design which shows the title and author. I wrote the first version of the drawing code in Pillow, because that’s what I’m familiar with. It was fine, but the code was quite flimsy – it didn’t wrap properly for long titles, and I couldn’t get custom fonts to work. Later I rewrote the app in JavaScript, so I had access to the HTML canvas element. This is another tool that I haven’t worked with before, so a fun chance to learn something new. The API felt fairly familiar, similar to other APIs I’ve used to build HTML elements. This time I did implement some line wrapping – there’s a measureText() API for canvas, so you can see how much space text will take up before you draw it. I break the text into words, and keeping adding words to a line until measureText tells me the line is going to overflow the page. I have lots of ideas for how I could improve the line wrapping, but it’s good enough for now. I was also able to get fonts working, so I picked Georgia to match the font used for titles on AO3. Here are some examples: I had several ideas for choosing the background colour. I’m trying to help my friend browse her collection of fic, and colour would be a useful way to distinguish things – so how do I use it? I realised I could get the fandom from the EPUB file, so I decided to use that. I use the fandom name as a seed to a random number generator, then I pick a random colour. This means that all the fics in the same fandom will get the same colour – for example, all the Star Wars stories are a shade of red, while Star Trek are a bluey-green. This was a bit harder than I expected, because it turns out that JavaScript doesn’t have a built-in seeded random number generator – I ended up using some snippets from a Stack Overflow answer, where bryc has written several pseudorandom number generators in plain JavaScript. I didn’t realise until later, but I designed something similar to the placeholder book covers in the Apple Books app. I don’t use Apple Books that often so it wasn’t a deliberate choice to mimic this style, but clearly it was somewhere in my subconscious. One difference is that Apple’s app seems to be picking from a small selection of background colours, whereas my code can pick a much nicer variety of colours. Apple’s choices will have been pre-approved by a designer to look good, but I think mine is more fun. Add the cover image to the EPUB My first attempt to add a cover image used pandoc: pandoc input.epub --output output.epub --epub-cover-image cover.jpeg This approach was no good: although it added the cover image, it destroyed the formatting in the rest of the EPUB. This made it easier to find the fic, but harder to read once you’d found it. An EPUB file I downloaded from AO3, before/after it was processed by pandoc. So I tried to do it myself, and it turned out to be quite easy! I unzipped another EPUB which already had a cover image. I found the cover image in OPS/images/cover.jpg, and then I looked for references to it in content.opf. I found two elements that referred to cover images: <?xml version="1.0" encoding="UTF-8"?> <package xmlns="http://www.idpf.org/2007/opf" version="3.0" unique-identifier="PrimaryID"> <metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf"> <meta name="cover" content="cover-image"/> … </metadata> <manifest> <item id="cover-image" href="images/cover.jpg" media-type="image/jpeg" properties="cover-image"/> … </manifest> </package> This gave me the steps for adding a cover image to an EPUB file: add the image file to the zipped bundle, then add these two elements to the content.opf. Where am I going to deploy this? I wrote the initial prototype of this in Python, because that’s the language I’m most familiar with. Python has all the libraries I need: The zipfile module can unpack and modify the EPUB/ZIP The xml.etree or lxml modules can manipulate XML The Pillow library can generate images I built a small Flask web app: you upload the EPUB to my server, my server does some processing, and sends the EPUB back to you. But for such a simple app, do I need a server? I tried rebuilding it as a static web page, doing all the processing in client-side JavaScript. That’s simpler for me to host, and it doesn’t involve a round-trip to my server. That has lots of other benefits – it’s faster, less of a privacy risk, and doesn’t require a persistent connection. I love static websites, so can they do this? Yes! I just had to find a different set of libraries: The JSZip library can unpack and modify the EPUB/ZIP, and is the only third-party code I’m using in the tool Browsers include DOMParser for manipulating XML I’ve already mentioned the HTML <canvas> element for rendering the image This took a bit longer because I’m not as familiar with JavaScript, but I got it working. As a bonus, this makes the tool very portable. Everything is bundled into a single HTML file, so if you download that file, you have the whole tool. If my friend finds this tool useful, she can save the file and keep a local copy of it – she doesn’t have to rely on my website to keep using it. What should it look like? My first design was very “engineer brain” – I just put the basic controls on the page. It was fine, but it wasn’t good. That might be okay, because the only person I need to be able to use this app is my friend – but wouldn’t it be nice if other people were able to use it? If they’re going to do that, they need to know what it is – most people aren’t going to read a 2,500 word blog post to understand a tool they’ve never heard of. (Although if you have read this far, I appreciate you!) I started designing a proper page, including some explanations and descriptions of what the tool is doing. I got something that felt pretty good, including FAQs and acknowledgements, and I added a grey area for the part where you actually upload and download your EPUBs, to draw the user’s eye and make it clear this is the important stuff. But even with that design, something was missing. I realised I was telling you I’d create covers, but not showing you what they’d look like. Aha! I sat down and made up a bunch of amusing titles for fanfic and fanfic authors, so now you see a sample of the covers before you upload your first EPUB: This makes it clearer what the app will do, and was a fun way to wrap up the project. What did I learn from this project? Don’t be scared of new file formats My first instinct was to look for a third-party library that could handle the “complexity” of EPUB files. In hindsight, I’m glad I didn’t find one – it forced me to learn more about how EPUBs work, and I realised I could write my own code using built-in libraries. EPUB files are essentially ZIP files, and I only had basic needs. I was able to write my own code. Because I didn’t rely on a library, now I know more about EPUBs, I have code that’s simpler and easier for me to understand, and I don’t have a dependency that may cause problems later. There are definitely some file formats where I need existing libraries (I’m not going to write my own JPEG parser, for example) – but I should be more open to writing my own code, and not jumping to add a dependency. Static websites can handle complex file manipulations I love static websites and I’ve used them for a lot of tasks, but mostly read-only display of information – not anything more complex or interactive. But modern JavaScript is very capable, and you can do a lot of things with it. Static pages aren’t just for static data. One of the first things I made that got popular was find untagged Tumblr posts, which was built as a static website because that’s all I knew how to build at the time. Somewhere in the intervening years, I forgot just how powerful static sites can be. I want to build more tools this way. Async JavaScript calls require careful handling The JSZip library I’m using has a lot of async functions, and this is my first time using async JavaScript. I got caught out several times, because I forgot to wait for async calls to finish properly. For example, I’m using canvas.toBlob to render the image, which is an async function. I wasn’t waiting for it to finish, and so the zip would be repackaged before the cover image was ready to add, and I got an EPUB with a missing image. Oops. I think I’ll always prefer the simplicity of synchronous code, but I’m sure I’ll get better at async JavaScript with practice. Final thoughts I know my friend will find this helpful, and that feels great. Writing software that’s designed for one person is my favourite software to write. It’s not hyper-scale, it won’t launch the next big startup, and it’s usually not breaking new technical ground – but it is useful. I can see how I’m making somebody’s life better, and isn’t that what computers are for? If other people like it, that’s a nice bonus, but I’m really thinking about that one person. Normally the one person I’m writing software for is me, so it’s extra nice when I can do it for somebody else. If you want to try this tool yourself, go to alexwlchan.net/my-tools/add-cover-to-ao3-epubs/ If you want to read the code, it’s all on GitHub.

Non-alcoholic apéritifs

I’ve been doing Dry January this year. One thing I missed was something for apéro hour, a beverage to mark the start of the evening. Something complex and maybe bitter, not like a drink you’d have with lunch. I found some good options. Ghia sodas are my favorite. Ghia is an NA apéritif based on grape juice but with enough bitterness (gentian) and sourness (yuzu) to be interesting. You can buy a bottle and mix it with soda yourself but I like the little cans with extra flavoring. The Ginger and the Sumac & Chili are both great. Another thing I like are low-sugar fancy soda pops. Not diet drinks, they still have a little sugar, but typically 50 calories a can. De La Calle Tepache is my favorite. Fermented pineapple is delicious and they have some fun flavors. Culture Pop is also good. A friend gave me the Zero book, a drinks cookbook from the fancy restaurant Alinea. This book is a little aspirational but the recipes are doable, it’s just a lot of labor. Very fancy high end drink mixing, really beautiful flavor ideas. The only thing I made was their gin substitute (mostly junipers extracted in glycerin) and it was too sweet for me. Need to find the right use for it, a martini definitely ain’t it. An easier homemade drink is this Nonalcoholic Dirty Lemon Tonic. It’s basically a lemonade heavily flavored with salted preserved lemons, then mixed with tonic. I love the complexity and freshness of this drink and enjoy it on its own merits. Finally, non-alcoholic beer has gotten a lot better in the last few years thanks to manufacturing innovations. I’ve been enjoying NA Black Butte Porter, Stella Artois 0.0, Heineken 0.0. They basically all taste just like their alcoholic uncles, no compromise. One thing to note about non-alcoholic substitutes is they are not cheap. They’ve become a big high end business. Expect to pay the same for an NA drink as one with alcohol even though they aren’t taxed nearly as much.

It burns

The first time we had to evacuate Malibu this season was during the Franklin fire in early December. We went to bed with our bags packed, thinking they'd probably get it under control. But by 2am, the roaring blades of fire choppers shaking the house got us up. As we sped down the canyon towards Pacific Coast Highway (PCH), the fire had reached the ridge across from ours, and flames were blazing large out the car windows. It felt like we had left the evacuation a little too late, but they eventually did get Franklin under control before it reached us. Humans have a strange relationship with risk and disasters. We're so prone to wishful thinking and bad pattern matching. I remember people being shocked when the flames jumped the PCH during the Woolsey fire in 2017. IT HAD NEVER DONE THAT! So several friends of ours had to suddenly escape a nightmare scenario, driving through burning streets, in heavy smoke, with literally their lives on the line. Because the past had failed to predict the future. I feel into that same trap for a moment with the dramatic proclamations of wind and fire weather in the days leading up to January 7. Warning after warning of "extremely dangerous, life-threatening wind" coming from the City of Malibu, and that overly-bureaucratic-but-still-ominous "Particularly Dangerous Situation" designation. Because, really, how much worse could it be? Turns out, a lot. It was a little before noon on the 7th when we first saw the big plumes of smoke rise from the Palisades fire. And immediately the pattern matching ran astray. Oh, it's probably just like Franklin. It's not big yet, they'll get it out. They usually do. Well, they didn't. By the late afternoon, we had once more packed our bags, and by then it was also clear that things actually were different this time. Different worse. Different enough that even Santa Monica didn't feel like it was assured to be safe. So we headed far North, to be sure that we wouldn't have to evacuate again. Turned out to be a good move. Because by now, into the evening, few people in the connected world hadn't started to see the catastrophic images emerging from the Palisades and Eaton fires. Well over 10,000 houses would ultimately burn. Entire neighborhoods leveled. Pictures that could be mistaken for World War II. Utter and complete destruction. By the night of the 7th, the fire reached our canyon, and it tore through the chaparral and brush that'd been building since the last big fire that area saw in 1993. Out of some 150 houses in our immediate vicinity, nearly a hundred burned to the ground. Including the first house we moved to in Malibu back in 2009. But thankfully not ours. That's of course a huge relief. This was and is our Malibu Dream House. The site of that gorgeous home office I'm so fond to share views from. Our home. But a house left standing in a disaster zone is still a disaster. The flames reached all the way up to the base of our construction, incinerated much of our landscaping, and devoured the power poles around it to dysfunction. We have burnt-out buildings every which way the eye looks. The national guard is still stationed at road blocks on the access roads. Utility workers are tearing down the entire power grid to rebuild it from scratch. It's going to be a long time before this is comfortably habitable again. So we left. That in itself feels like defeat. There's an urge to stay put, and to help, in whatever helpless ways you can. But with three school-age children who've already missed over a months worth of learning from power outages, fire threats, actual fires, and now mudslide dangers, it was time to go. None of this came as a surprise, mind you. After Woolsey in 2017, Malibu life always felt like living on borrowed time to us. We knew it, even accepted it. Beautiful enough to be worth the risk, we said.  But even if it wasn't a surprise, it's still a shock. The sheer devastation, especially in the Palisades, went far beyond our normal range of comprehension. Bounded, as it always is, by past experiences. Thus, we find ourselves back in Copenhagen. A safe haven for calamities of all sorts. We lived here for three years during the pandemic, so it just made sense to use it for refuge once more. The kids' old international school accepted them right back in, and past friendships were quickly rebooted. I don't know how long it's going to be this time. And that's an odd feeling to have, just as America has been turning a corner, and just as the optimism is back in so many areas. Of the twenty years I've spent in America, this feels like the most exciting time to be part of the exceptionalism that the US of A offers. And of course we still are. I'll still be in the US all the time on both business, racing, and family trips. But it won't be exclusively so for a while, and it won't be from our Malibu Dream House. And that burns.

Slow, flaky, and failing

Thou shalt not suffer a flaky test to live, because it’s annoying, counterproductive, and dangerous: one day it might fail for real, and you won’t notice. Here’s what to do.
