I made a macOS "screen recall" app, JustNow: Run it, let it record, rewind screen to find & copy old text or screenshots. Freeeee! Get it at justnow.tk.sg and let me know if you use it, because my agents and I couldn't be bothered to build telemetry.

Asked ChatGPT 4.5 to generate a line drawing of my cat and, with all that compute, it… plotted the image out in matplotlib. What

The latest DeepSeek app update added an amazing new feature: A welcome sheet, localised for Singapore with “Welcome to DeepSeek lah”. This company is truly light years ahead of the competition, selling all my other AI stock rn

Please check out and wishlist on Steam this game from my very talented former student @bucketfish.me!

Got Gemini to summarise a Google Meet call, and in the document it used two spaces after each full stop and brought back all my nightmare times in the civil service. AI must be stopped at all costs.

Excuse me Reminders app what are you doing

Happy to be at #iosconfsg 2025, this time as a sponsor! Tinkercademy is an education sponsor this year, though we have no idea what that actually means.

Should probably be in disguise when setting up a xiaohongshu discount

I only just found out a free re-release of Star Control II came out last year (and there’s a sequel in the works)! I spent so many hours on this as a kid. store.steampowered.com/app/2645580/...

A city-building game, set in Singapore, inspired by Balatro, where your points are affected by the MPs in your Cabinet. Does this mean we legitimately get to declare "My MP is such a joker" tnp.straitstimes.com/lifestyle/ot...

Is... is the Singapore Zoo killing off Snoopy

I just got an email from a marketing company titled “Deck the halls with SEO” and I cannot think of anything more horrific

Ooh I unlocked iOS widgets in Christmas tree mode

I read somewhere that we should maximise ChatGPT o1's thinking by ending a prompt with "use at least 1000 reasoning tokens", so I now have a 2,000-word opus expounding on what size uniforms I should buy for my primary school-entering kiddo based on some data points I sent in. AI is hilarious.

From the Swift class chat

My Messages app on macOS has been giving me 3 unread messages all week, and I got the answer on how to clear them from Claude — ask Siri to "read me my messages". Now I'm just super annoyed at the spammers who sent messages that got filtered on my phone but not my Mac.

I've been recording videos to go along with our new — hopefully beginner-friendly — tutorials on various Swift concepts for learners. This one has socks. swiftinsg.org/learn/option... #SwiftUI

“Thank you for your loyalty to Citi”, my notification tells me every month like I’m a subject of their kingdom paying my tribute

Made an attempt at updating my Swift class’ todo list app to SwiftData. Filtering with predicates doesn’t seem to be worth the pedagogical overhead right now… github.com/yjsoon/swift... #SwiftUI

What in the actual world is this UI, Amazon

Asked my interns to look into preparing curriculum for a Figma class, and I’m just glad autocorrect didn’t change it to Sigma

Useless fact from today’s surprising Stanford football victory: 30 of our 38 points were by Emmetts www.espn.com/college-foot...

Look, kid, mango sticky rice isn’t that hard to make. All you need are: 1. Mango 2. Rice 3. Sticks

If, in any group chat you’re in, someone mentions a vacuum cleaner, you are legally obliged to reply to it and say “That sucks….”

Apple now provides 3.2x more RAM on their laptops than free tier iCloud storage

The best feature of Apple Intelligence so far is that it’s made Apple raise the base model RAM to 16GB across Mac devices

#TheWildRobot got me to croak an audible sob in more than one scene, which doesn’t often happen in movies about robots and geese I watch with my kids. 5 of 5 stars.

How to greatly increase your enjoyment of #VenomTheLastDance : when Venom is off-screen, imagine him being voiced by an unhinged Cookie Monster. 4 out of 5 stars.

Google Pay are you for real here

Been back on X a lot lately thanks to the wild American college conference realignment news. The algorithm over there really does a good job with breaking news. Also RIP to my school’s Pac12 conference, sad

Here is a chicken

amazing, my knife is magsafe wallet compatible

Well that was an interesting first weekend on Threads. The difference for me has been that my students are on there — all gen Z IG users who never bothered with Twitter.

A day later, Threads really is like IG but with text: Brands all over the algorithmic feed and a slew of inane replies. I miss old Twitter.

What the I haven’t even read 600 posts

Oh Threads is here goodbye then

Managed to get Mona for Mastodon set up with Bluesky via Sky Bridge, and marvelling at how this sentence would have made no sense a year ago

Got the flu and now the fridge is broken. That is one infectious bug

Handle updating here is surprisingly quick and easy! (glares at Yjsoon account on the Mastodon instance I’m on, where I accidentally capitalised the first letter of my username and can’t change it painlessly)

Thanks fellow human @thedak.bsky.social for the invite!
