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.

My favorite memory of my M1 Pro MacBook Pro was the whole sensation of “holy crap, you never hear the fans in this thing”, which was very novel in 2021. Four years later, this MacBook Pro is still a delight. It’s the longest I’ve ever owned a laptop, and while I’d love to pick up the new M4 goodness, this dang thing still seems to just shrug at basically anything I throw at it. Video editing, code compiling, CAD models, the works. (My desire to update is helped though by the fact I got the 2TB SSD, 32GB RAM option, and upgrading to those on new MacBooks is still eye wateringly expensive.) But my MacBook is starting to show its age in one area: it’s not quiet anymore. If you’re doing anything too intensive like compiling code for awhile, or converting something in Handbrake, the age of the fans being quiet is long past. The fans are properly loud. (And despite having two cats, it’s not them! I clean out the fans pretty regularly.) Enter the thermal paste Everyone online seems to point toward one thing: the thermal paste on computers tends to dry up over the years. What the heck is thermal paste? Well, components on your computer that generate a lot of heat are normally made to touch something like a copper heatsink that is really good at pulling that heat away from it. The issue is, when you press these two metal surfaces against each other, even the best machining isn’t perfect and you there’s microscopic gaps between them meaning there’s just air at those parts, and air is a terrible conductor of heat. The solution is to put a little bit of thermal paste (basically a special grey toothpaste gunk that is really good at transferring heat) between them, and it fills in any of those microscopic gaps. The problem with this solution is after hundreds and hundreds of days of intense heat, the paste can dry up into something closer to almost a powder, and it’s not nearly as good at filling in those gaps. Replacement time The logic board! MacBook thermal paste isn’t anything crazy (for the most part, see below), custom PC builders use thermal paste all the time so incredibly performant options are available online. I grabbed a tube of Noctua NT-H2 for about $10 and set to taking apart my MacBook to swap out the aging thermal paste. And thankfully, iFixit has a tremendous, in depth guide on the disassembly required, so I got to it. Indeed, that grey thermal paste looked quite old, but also above and below it (on the RAM chips) I noticed something that didn’t quite seem like thermal paste, it was far more… grainy almost? Spottiness is due to half of it being on the heatsink It turns out, ending with my generation of MacBooks (lucky me!) Apple used a very special kind of thermal compound often called “Carbon Black”, which is basically designed to be able to bridge an even thicker gap than traditional thermal paste. I thought about replacing it, but it seems really hard to come across that special thermal compound (and do not do it with normal thermal paste) and my RAM temperatures always seemed fine (65°C is fine… right?) so I just made sure to not touch that. For the regular grey thermal paste, I used some cotton swabs and isopropyl alcohol to remove the dried up existing thermal paste, then painted on a bit of the new stuff. Disaster To get to the underside of the CPU, you basically need to disassemble the entire MacBook. It’s honestly not that hard, but iFixit warned that the fan cables (which also need to be unclipped) are incredibly delicate. And they’re not wrong, seriously they have the structural integrity of the half-ply toilet paper available at gas stations. So, wouldn’t you know it, I moved the left fan’s cable a bit too hard and it completely tore in half. Gah. I found a replacement fan online (yeah you can’t just buy the cable, need a whole new fan) and in the meantime I just kept an eye on my CPU thermals. As long as I wasn’t doing anything too intensive it honestly always stayed around 65° which was warm, but not terrifying (MacBook Airs completely lack a fan, after all). Take two A few days later, the fans arrived, and I basically had to redo the entire disassembly process to get to the fans. At least I was a lot faster this time. The fan was incredibly easy to swap out (hats off there, Apple!) and I screwed everything back together and began reconnecting all the little connectors. Until I saw it: the tiny (made of the same half ply material as the fan cable) Touch ID sensor cable was inexpicably torn in half, the top half just hanging out. I didn’t even half to touch this thing really, and I hadn’t even got to the stage of reconnecting it (I was about to!), it comes from underneath the logic board and I guess just the movement of sliding the logic board back in sheared it in half. me Bah. I looked up if I could just grab another replacement cable here, and sure enough you can… but the Touch ID chip is cryptographically paired to your MacBook so you’d have to take it into an Apple Store. Estimates seemed to be in the hundreds of dollars, so if anyone has any experience there let me know, but for now I’m just going to live happily without a Touch ID sensor… or the button because the button also does not work. RIP little buddy (And yeah I’m 99.9% sure I can’t solder this back together, there’s a bunch of tiny lanes that make up the cable that you would need experience with proper micro-soldering to do.) Honestly, the disassembly process for my MacBook was surprisingly friendly and not very difficult, I just really wish they beefed up some of the cables even slightly so they weren’t so delicate. The results I was going to cackle if I went through all that just to have identical temperatures as before, but I’m very happy to say they actually improved a fair bit. I ran a Cinebench test before disassembling the MacBook the very first time to establish a baseline: Max CPU temperature: 102°C Max fan speed: 6,300 RPM Cinbench score: 12,252 After the new thermal paste (and the left fan being new): Max CPU temperature: 96°C Max fan speed: 4,700 RPM Cinbench score: 12,316 Now just looking at those scores you might be like… so? But let me tell you, dropping 1,600 RPM on the fan is a noticeable change, it goes from “Oh my god this is annoyingly loud” to “Oh look the fans kicked in”, and despite slower fan speeds there was still a decent drop in CPU temperature! And a 0.5% higher Cinebench score! But where I also really notice it is in idling: just writing this blog post my CPU was right at 46°C the whole time, where previously my computer idled right aroud 60°C. The whole computer just feels a bit healthier. So… should you do it? Honestly, unless you’re very used to working on small, delicate electronics, probably not. But if you do have that experience and are very careful, or have a local repair shop that can do it for a reasonable fee (and your MacBook is a few years old so as to warrant it) it’s honestly a really nice tweak that I feel will hopefully at least get me to the M5 generation. I do miss Touch ID, though.
