This summer in Berlin, a group of artists, designers, and curious minds gathered around a creative question: What can parasites teach us about robotics? Led by Salvador Marino, a transdisciplinary artist with a PhD in biology, the workshop “Parasites and Robotics” invited participants to explore the intersection of biology, sci-fi, and open-source hardware – all […] The post Exploring the edge of design and biology with Arduino: inside the “Parasites and Robotics” workshop appeared first on Arduino Blog.

Okay, I have to be doing something astronomically stupid, right? This should be working? I’m playing around with an App Clip and want to just run it on the device as a test, but no matter how I set things up nothing ever works. If you see what I’m doing wrong let me know and I’ll update this, and hopefully we can save someone else in the future a few hours of banging their head! Xcode App Clips require some setup in App Store Connect, so Apple provides a way when you’re just testing things to side step all that: App Clip Local Experiences I create a new sample project called IceCreamStore, which has the bundle ID com.christianselig.IceCreamStore. I then go to File > New > Target… > App Clip. I choose the Product Name “IceCreamClip”, and it automatically gets the bundle ID com.christianselig.IceCreamStore.Clip. I run both the main target and the app clip target on my iOS 18.6 phone and everything shows up perfectly, so let’s go onto actually configuring the Local Experience. Local Experience setup I go to Settings.app > Developer > App Clips Testing > Local Experiences > Register Local Experience, and then input the following details: URL Prefix: https://boop.com/beep/ Bundle ID: com.christianselig.IceCreamStore.Clip (note thne Apple guide above says to use the Clip’s bundle ID, but I have tried both) Title: Test1 Subtitle: Test2 Action: Open Upon saving, I then send myself a link to https://boop.com/beep/123 in iMessage, and upon tapping on it… nothing, it just tries to open that URL in Safari rather than in an App Clip (as it presumably should?). Same thing if I paste the URL into Safari’s address bar directly. Help What’s the deal here, what am I doing wrong? Is my App Store Connect account conspiring against me? I’ve tried on multiple iPhones on both iOS 18 and 26, and the incredible Matt Heaney (wrangler of App Clips) even kindly spent a bunch of time also pulling his hair out over this. We even tried to see if my devices were somehow banned from using App Clips, but nope, production apps using App Clips work fine! If you figure this out you would be my favorite person. 😛

Being chronically late to meetings sucks. Not only is it very rude, but you’re signalling that you don’t value your coworkers’ time. However, I’ve picked up a technique that works unreasonably well within a team.1 If you are late to the first meeting of the day three times within a quarter, then you will have to make pancakes for the whole team. Let’s say that you have a daily stand-up taking place at 10:00. Arriving at 10:00:59: completely OK. Arriving at 10:01:00: You’re one step closer to making pancakes! Keep in mind that you may hit some obstacles when implementing this rule, so feel free to adjust it. When proposing this idea in my current team, I learned that the office does not offer pancake-making facilities. The pancakes can be substituted for other types of cake or bringing in something else, as long as the team gives prior approval of that modification. The pancake strikes can also be pooled together and spent with your teammates if they wish to do so. If you’re struggling with your team being late to your daily meeting(s), then go ahead and add this rule to the working agreement. You do have a working agreement set up, right? Right? And a free security tech tip to close out: if you see an unlocked work laptop at the office, open your internal chat application of choice on it and try posting to a public channel that you’ll be bringing cake/beers/candy to the office. Works wonders for enforcing the habit of locking your laptop up when leaving the desk! to be fair, the sample size is two, but it has worked out really well in both! ↩︎

In the worlds of programming and robotics, turtles are entities — either virtual or physical robots— that follow commands to move around a 2D plane. Those are usually very simple commands, such as “move forward 10 units” or “rotate 90 degrees clockwise,” and they help people learn some programming fundamentals (like Logo in the ’80s!)

It was probably going to happen sooner or later, but Microsoft has officially released the source code for 6502 BASIC. The specific revision is very Commodore-centric: it's the 1977 "8K" BASIC variant "1.1," which Commodore users know better as BASIC V2.0, the same BASIC used in the early PET and with later spot changes from Commodore (including removing Bill Gates' famous Easter egg) in the VIC-20 and Commodore 64. I put "8K" in quotes because the 40-bit Microsoft Binary Format version, which is most familiar as the native floating point format for most 8-bit BASICs derived from Microsoft's and all Commodore BASICs from the PET on up, actually starts at 9K in size. In the C64, because there is RAM and I/O between the BASIC ROM and the Kernal ROM, there is an extra JMP at the end of the BASIC ROM to continue to the routine in the lowest portions of the Kernal ROM. The jump doesn't exist in the VIC-20 where the ROM is contiguous and as a result everything past that point is shifted by three bytes on the C64, the length of the instruction. This is, of course, the same BASIC that Gates wanted a percentage of but Jack Tramiel famously refused to budge on the $25,000 one-time fee, claiming "I'm already married." Gates yielded to Tramiel, as most people did then, but I suspect the slight was never forgotten. Not until the 128 did Microsoft officially appear in the credits for Commodore BASIC, and then likely only as a way to push its bona fides as a low-end business computer. Microsoft's source release also includes changes from Commodore's own John Feagans, who rewrote the garbage collection routine, and was the original developer of the Commodore Kernal and later Magic Desk. The source code is all in one big file (typical for the time) and supports six machine models, the first most likely a vapourware 6502 system never finished by Canadian company Semi-Tech Microelectronics (STM) better known for the CP/M-based Pied Piper, then the Apple II, the Commodore (in this case PET 2001), the Ohio Scientific (OSI) Challenger, the Commodore/MOS KIM-1, and most intriguingly a PDP-10-based simulator written by Paul Allen. The source code, in fact, was cross-assembled on a PDP-10 using MACRO-10, and when assembled for the PDP-10 emulator it actually emits a PDP-10 executable that traps on every instruction into the simulator linked with it — an interesting way of effectively accomplishing threaded code. A similar setup was used for their 8080 emulator. Unfortunately, I don't believe Allen's code has been released anywhere, though I'd love to be proven wrong if people know otherwise. Note that they presently don't even mention the STM port in the Github README, possibly because no one was sure what it did. While MACRO-10 source for 6502 BASIC has circulated before and been analysed in detail, most notably by Michael Steil, this is nevertheless the first official release where it is truly open-source under the MIT license and Microsoft should be commended for doing so. This also makes it much easier to pull a BASIC up for your own 6502 homebrew system — there's nothing like the original.
