Since my last piece about Bluesky, I’ve been using the service a lot more. Just about everyone I followed on other services is there now, and it’s way more fun than late-stage Twitter ever was. Halifax is particularly into Bluesky, which reminds me of our local scene during the late-2000s/early-2010s Twitter era. That said, I still have reservations about the service. Primarily around the whole decentralized/federated piece. The Bluesky team continues to work toward the goal of creating a decentralized and open protocol, but they’ve got quite a way to go. Part of my fascination with Bluesky is due to its radical openness. There is no similar service that allows users unauthenticated access to the firehose, or that publishes in-depth stats around user behaviour and retention. I like watching numbers go up, so I enjoy following those stats and collecting some of my own. A few days ago I noticed that the rate of user growth was accelerating. Growth had dropped off steadily since late January. As of this writing, there are currently around 5 users a second signing up for the service. It was happening around the same time as tariff news was dropping, but that didn’t seem like a major driver. Turned out that the bigger cause was a new Tiktok-like video sharing app called Skylight Social. I was a bit behind on tech news, so I missed when TechCrunch covered the app. It’s gathered more steam since then, and today is one of the highest days for new Bluesky signups since the US election. As per the TechCrunch story, Skylight has been given some initial funding by Mark Cuban. It’s also selling itself as “decentralized” and “unbannable”. I’m happy for their success, especially given how unclear the Tiktok situation is, but I continue to feel like everyone’s getting credit for work they haven’t done yet. Skylight Social goes out of its way to say that it’s powered by the AT Protocol. They’re not lying, but I think it’s truer at the moment to say that the app is powered by Bluesky. In fact, the first thing you see when launching the app is a prompt to sign up for a “BlueSky” account 1 if you don’t already have one. The Bluesky team are working on better ways to handle this, but it’s work that isn’t completed. At the moment, Skylight is not decentralized. I decided to sign up and test the service out, but this wasn’t a smooth experience. I started by creating an App Password, and tried logging using the “Continue with Bluesky” button. I used both my username and email address along with the app password, but both failed with a “wrong identifier or password” error. I saw a few other people having the same issue. It wasn’t until later that I tried using the “Sign in to your PDS” route, which ended up working fine. The only issue: I don’t run my own PDS! I just use custom domain name on top of Bluesky’s first-party PDS. In fact, it looks like third-party PDSs might not even be supported at the moment. Even if/when you can sign up with a third-party PDS, this is just a data storage and authentication platform. You’re still relying on Skylight and Bluesky’s services to shuttle the data around and show it to you. I’m not trying to beat up on Skylight specifically. I want more apps to be built with open standards, and I think TikTok could use a replacement — especially given that something is about to happen tomorrow. I honestly wish them luck! I just think the “decentralized” and “unbannable” copy on their website should currently be taken with a shaker or two of salt. I don’t know why, but seeing “BlueSky” camel-cased drives me nuts. Most of the Skylight Social marketing material doesn’t make this mistake, but I find it irritating to see during the first launch experience. ↩
Tom Scott is playing to win. The intro music made me wonder if the Wendover team watch c90dventures. At one point in the episode, Adam breaks out some Scatman. This is going to be a great season.
I was late to the party, but I played Luck Be a Landlord last year and really enjoyed it. It’s a deckbuilder where you build combos by manipulating the icons in your custom slot machine. I linked above to the Steam page, but it’s on just about every platform — I played through it on iOS. TrampolineTales, the indie developer behind Luck Be a Landlord, released a demo for Maze Mice as part of Steam Next Fest. I got around to giving the demo a shot today and I loved it! The game is a slightly weird mix of Pac-Man and Vampire Survivors where time only progresses when you move. You pilot a mouse around a cardboard maze and collect XP gems to earn new weapons and passive effects. You’re being chased by cats and ghosts — the cats follow your path exactly around the maze, and the ghosts ignore walls as they move directly toward you. The time progression system is fun, and I found myself just squeezing through some tight spots by tapping the arrow keys. There’s some light strategy required to herd your foes away from the gems you want to collect. You can check out the Steam page for Maze Mice and give the demo a go on macOS or Windows. If you liked Vampire Survivors, I think you’ll have a good time with this as well.
I was recently on-site with a client and noticed that one person was using the new “Macintosh” screen saver that was added in macOS Sequoia. If you haven’t seen it, here’s a video of it in action. I knew that the screen saver had released, but I was very happy with Relay’s St. Jude screen saver by James Thomson. Happily it turns out that you can run two different screen savers on macOS if you have more than one monitor. To get this working under macOS Sequoia, first make sure your monitors set up as different “Spaces”. You can do this by heading to System Settings ➔ Desktop & Dock, and under the “Mission Control” section, make sure “Displays have separate Spaces” is enabled. Then you can head to System Settings ➔ Screen Saver, and turn off “Show on all Spaces” to the left of the preview thumbnail. Now you can use the drop-down below the thumbnail to choose which monitor you want to configure. I chose to set up the Macintosh screen saver on my secondary monitor, which is in portrait orientation. I set it to the “Spectrum” colour setting (same as in the example video linked above), and also enabled “Show as wallpaper”. This has the nice effect of having the screen saver ease out of its animation and into the desktop wallpaper for that monitor when you wake your machine. I switched to the Mac in 2002 with the release of Mac OS X Jaguar. Previously, I lived in the PC world and didn’t have much love for anything Apple-related. After I switched, I found myself curious about the earlier days of the Mac. This screen saver made me want to dig further into some of the details. A nice effect of the screen saver and its wallpaper mode is the subtle shadowing on the chunky pixels. I’m assuming this is a nod to the Macintosh Portable and its early active-matrix LCD. The screen on the Portable had a distinctive “floating pixel” look. I love how this looks, though I think it would have been a pain to use day-to-day. Colin Wirth produced an excellent video about the machine on his channel “This Does Not Compute”. You can see the some close-ups of the effect starting around the 2:30 mark. Watching the screen saver also had me curious about what version of system software was being shown off. Turns out it’s more than one. Two tools I used to start looking into this were GUIdebook’s screenshots section and Infinite Mac — a site that lets you run fully-loaded versions of classic Macs in your browser. I was most fascinated when the screen saver scrolled over versions of the Control Panel. Especially the version from System 1. You can see this starting at 0:12 in the example video. This thing is a marvel of user interface design. Pretty much everything that can be configured about the original Macintosh is shown, without words, in this gem of a screen. Low End Mac has a good overview of what’s going on here, but I feel like it’s the sort of thing you could intuit if you played with it for a minute or two. One thing I learned while writing this is that you can click the menu bar in the desktop background preview to cycle through some presets! My only nitpicks about this screen are that it uses a strange XOR’d cross instead of the default mouse pointer. I’m assuming this was to make it easier to edit the desktop background, but it still feels like an odd choice. Also, the box with controls how many time the menu blinks is one pixel narrower than the two boxes below it. This would have driven me insane, and I’m amazed it still looked this way System 2.1. The Macintosh screen saver shows its time based on your system clock. I use 24-hour time, and that’s respected in the screen saver even when it’s showing the original Control Panel. This, ironically, is an anachronism. 24-hour time wasn’t an option until System 4. The screen saver also includes a version of Control Panel from System 6. You can see this at around 9:08 in the example video. This Control Panel shows its version as 3.3.3 in the bottom left. I believe this makes it System 6.0.7 or 6.0.8. You can run System 6.0.8 using an emulator on Archive.org. While this version allows for many more options, it’s far less playful. This general style — with the scrollable list of setting sections on the left — started with System 4. System 3 had the last all-in-one Control Panel layout. System 7 migrated to the Control Panels folder, where each panel is its own file, and you could easily add third-party panels to the system. Anyway, this has been far too many words about a screen saver released eight months ago. If you find this interesting, I encourage you to give the Macintosh screen saver a go. I also recommend poking around at old versions of classic Mac OS. I had a lot of fun digging into this!
Today, Alec Watson posted a video titled “Algorithms are breaking how we think” on his YouTube channel, Technology Connections. The whole thing is excellent and very well argued. The main thrust is: people seem increasingly less mindful about the stuff they engage with. Watson argues that this is bad, and I agree. A little while ago I watched a video by Hank Green called “$4.5M to Spray Alcoholic Rats with Bobcat Urine”. Green has been banging this drum for a while. He hits some of the same notes as Watson, but from a different angle. This last month has been a lot, and I’ve withdrawn from news and social media quite a bit because of it. Part of this is because I’ve been very busy with work, but it’s also because I’ve felt overwhelmed. There are now a lot of bad-faith actors in positions of power. Part of their game plan is to spray a mass of obviously false, intellectually shallow, enraging nonsense into the world as quickly as possible. At a certain point the bullshit seeps in if you’re soaking in it. The ability to control over what you see next is powerful. I think it would be great if more people started being a bit more choosy about who they give that control to.

It isn’t a secret that many kids find math to be boring and it is easy for them to develop an attitude of “when am I ever going to use this?” But math is incredibly useful in the real world, from blue-collar machinists using trigonometry to quantum physicists unveiling the secrets of our universe through […] The post This unique electronic toy helps children learn their shapes appeared first on Arduino Blog.
I have worked with a few software developers who made the switch to this industry in the middle of their careers. A major change like that can be scary and raise a lot of fears and doubts, but I can attest that this can work out well with the right personality traits and a supporting environment. Here’s what I’ve observed. To keep the writing concise, I’ll be using the phrase “senior junior”1 to describe those that have made such a career switch. Overcoming the fear Fear is a natural reaction to any major change in life, especially when there’s risk of taking a financial hit while you have a family to support and a home loan to pay. The best mitigation that I’ve heard is believing that you can make the change, successfully. It sounds like an oversimplification, sure, as all it does is that it removes a mental blocker and throws out the self-doubt. And yet it works unreasonably well. It also helps if you have at least some savings to help mitigate the financial risk. A years’ worth of expenses saved up can go a long way in providing a solid safety net. What makes them succeed A great software developer is not someone that simply slings some code over the wall and spends all of their day working only on the technical stuff, there are quite a few critical skills that one needs to succeed. This is not an exhaustive list, but I’ve personally observed that the following ones are the most critical: ability to work in a team great communication skills conflict resolution ability to make decisions in the context of product development and business goals maintaining an environment of psychological safety Those with more than a decade of experience in another role or industry will most likely have a lot of these skills covered already, and they can bring that skill set into a software development team while working with the team to build their technical skill set. Software development is not special, at the end of they day, you’re still interacting with humans and everything that comes with that, good or bad. After working with juniors that are fresh out of school and “senior juniors” who have more career experience than I do, I have concluded that the ones that end up being great software developers have one thing in common: the passion and drive to learn everything about the role and the work we do. One highlight that I often like to share in discussions is one software developer who used to work in manufacturing. At some point they got interested in learning how they can use software to make work more efficient. They started with an MVP solution involving a big TV and Google Sheets, then they started learning about web development for a solution in a different area of the business, and ended up building a basic inventory system for the warehouse. After 2-3 years of self-learning outside of work hours and deploying to production in the most literal sense, they ended up joining my team. They got up to speed very quickly and ended up being a very valuable contributor in the team. In another example, I have worked with someone who previously held a position as a technical draftsman and 3D designer in a ship building factory (professionals call it a shipyard), but after some twists and turns ended up at a course for those interested in making a career switch, which led to them eventually working in the same company I do. Now they ship builds with confidence while making sure that the critical system we are working on stays stable. That developer also kicks my ass in foosball about 99% of the time. The domain knowledge advantage The combination of industry experience and software development skills is an incredibly powerful one. When a software developer starts work in a project, they learn the business domain piece by piece, eventually reaching a state where they have a slight idea about how the business operates, but never the full picture. Speaking with their end users will help come a long way, but there are always some details that get lost in that process. Someone coming from the industry will have in-depth knowledge about the business, how it operates, where the money comes from, what are the main pain points and where are the opportunities for automation. They will know what problems need solving, and the basic technical know-how on how to try solving them. Like a product owner, but on steroids. Software developers often fall into the trap of creating a startup to scratch that itch they have for building new things, or trying out technologies that have for a very long time been on their to-do list. The technical problems are fun to solve, sure, but the focus should be on the actual problem that needs fixing. If I wanted to start a new startup with someone, I’d look for someone working in an industry that I’m interested in and who understands the software development basics. Or maybe I’m just looking for an excellent product owner. How to help them succeed If you have a “senior junior” software developer on your team, then there really isn’t anything special you’d need to do compared to any other new joiner. Do your best to foster a culture of psychological safety, have regular 1-1s with them, and make sure to pair them up with more experienced team members as often as possible. A little bit of encouragement in challenging environments or periods of self-doubt can also go a long way. Temporary setbacks are temporary, after all. What about “AI”? Don’t worry about all that “AI”2 hype, if it was as successful in replacing all software development jobs as a lof of people like to shout from the rooftops, then it would have already done so. At best, it’s a slight productivity boost3 at the cost of a huge negative impact on the environment. Closing thoughts If you’re someone that has thought about working as a software developer or who is simply excited about all the ways that software can be used to solve actual business problems and build something from nothing, then I definitely recommend giving it a go, assuming that you have the safety net and risk appetite to do so. For reference, my journey towards software development looked like this, plus a few stints of working as a newspaper seller or a grocery store worker. who do you call a “senior senior” developer, a senile developer? ↩︎ spicy autocomplete engines (also known as LLM-s) do not count as actual artificial intelligence. ↩︎ what fascinates me about all the arguments around “AI” (LLM-s) is the feeling of being more productive. But how do you actually measure developer productivity, and do you account for possible reduced velocity later on when you’ve mistaken code generation speed as velocity and introduced hard to catch bugs into the code base that need to be resolved when they inevitably become an issue? ↩︎
I uploaded YouTube videos from time to time, and a fun comment I often get is “Whoa, this is in 8K!”. Even better, I’ve had comments from the like, seven people with 8K TVs that the video looks awesome on their TV. And you guessed it, I don’t record my videos in 8K! I record them in 4K and upscale them to 8K after the fact. There’s no shortage of AI video upscaling tools today, but they’re of varying quality, and some are great but quite expensive. The legendary Finn Voorhees created a really cool too though, called fx-upscale, that smartly leverages Apple’s built-in MetalFX framework. For the unfamiliar, this library is an extensive of Apple’s Metal graphics library, and adds functionality similar to NVIDIA’s DLSS where it intelligently upscales video using machine learning (AI), so rather than just stretching an image, it uses a model to try to infer what the frame would look like at a higher resolution. It’s primarily geared toward video game use, but Finn’s library shows it does an excellent job for video too. I think this is a really killer utility, and use it for all my videos. I even have a license for Topaz Video AI, which arguably works better, but takes an order of magnitude longer. For instance my recent 38 minute, 4K video took about an hour to render to 8K via fx-upscale on my M1 Pro MacBook Pro, but would take over 24 hours with Topaz Video AI. # Install with homebrew brew install finnvoor/tools/fx-upscale # Outputs a file named my-video Upscaled.mov fx-upscale my-video.mov --width 7680 --codec h265 Anyway, just wanted to give a tip toward a really cool tool! Finn’s even got a [version in the Mac App Store called Unsqueeze](https://apps.apple.com/ca/app/unsqueeze/id6475134617 Unsqueeze) with an actual GUI that’s even easier to use, but I really like the command line version because you get a bit more control over the output. 8K is kinda overkill for most use cases, so to be clear you can go from like, 1080p to 4K as well if you’re so inclined. I just really like 8K for the future proofing of it all, in however many years when 8K TVs are more common I’ll be able to have some of my videos already able to take advantage of that. And it takes long enough to upscale that I’d be surprised to see TVs or YouTube offering that upscaling natively in a way that looks as good given the amount of compute required currently. Obviously very zoomed in to show the difference easier If you ask me, for indie creators, even when 8K displays are more common, the future of recording still probably won’t be in native 8K. 4K recording gives so much detail still that have more than enough details to allow AI to do a compelling upscale to 8K. I think for my next camera I’m going to aim for recording in 6K (so I can still reframe in post), and then continue to output the final result in 4K to be AI upscaled. I’m coming for you, Lumix S1ii.
