LLMs write more code every day but they learned from the web’s existing (often insecure) codebase. Devs now need to catch what AI gets wrong, not just write from scratch. I built a hands-on course for that: patch a real vulnerable TS/Express app. boot.dev/courses/learn-web-security-typescript

Trying to keep to a post a day during August (Blaugust). I didn’t really have a lot of time to write today so here’s what we go up to. kevincunningham.co.uk/posts/a-non-...

I'm still trying to write once a day for Blaugust. This is day 3 where I reflect on my course creation process. It's good to be reminded that although I don't always have this written down, there is a process to my work. kevincunningham.co.uk/posts/what-i...

Second day of Blaugust and I follow the evolution of Linus Lee's thoughts on AI. kevincunningham.co.uk/posts/tracin...

I've moved from Inoreader to NetNewsWire to read my RSS feeds. I love it but it groups my feeds by publication and I don't know if it's possible to change it. Anyone use it and know if I'm missing something?

Was excited to take the kids to see the Odyssey on Wednesday. Went to book tickets and saw it's classified as a 15 so I can't take them. Sad times :(

The ESA released an amazing image of the Milky Way's center. 60 million stars - looks awesome! www.esa.int/Science_Expl...

Almost didn’t get them today. 🗺️ 23 June 2026 5/5 countries in 13/13 guesses 🟡🟠🟣🟡🟢 whereabouts.earth/daily/ #Whereabouts

Made an account today and started the spaces repetition to learn the countries I don’t know. Nice to have a mix between quiz and learning. 🗺️ 22 June 2026 5/5 countries in 8/13 guesses 🟡🟢🟠🟢🟢 whereabouts.earth/daily/ #Whereabouts

🗺️ 21 June 2026 5/5 countries in 11/13 guesses 🟢🟢🟡🟣🟡 whereabouts.earth/daily/ #Whereabouts Really enjoying @trey.io Whereabouts game - helping me to learn all the countries in the world one day at a time.

Search -> Ask -> Do This post talks about that journey in developing a research assistant in clinical sciences. I like the framing. Gives me language for why I don’t like Google AI summary - I want to choose which mode I’m in. martinfowler.com/articles/rel...

I’m not sure which is worse but I wouldn’t wear either of these. I mean even if we ignore the cameras and the surveillance and the …

TIL you can ignore files in git globally. Never again will a .DS_Store slip into a repo because I forgot to add it to the .gitignore! nelson.cloud/.gitignore-i...

I love maps and love this article from @greg.technology blog.greg.technology/2026/06/12/m... Atlas Obscura has amazing data which can be annoying to interact through exploding clusters: www.atlasobscura.com/articles/all... Greg's version makes me smile: gregsadetsky.github.io/clustering-i...

If you fancy some maths puzzles on this lovely Wednesday there are some good ones here. mathenchant.wordpress.com/2026/06/15/s... My family stopped listening after the first one.

Explain your @ I love learning and I think you need to “do” stuff to learn - dolearning And I am a developer and developer educator - .dev

> Many of us were taught hard work as a virtue, that if we put in the effort, and do the hard thing, that we will be rewarded. Some of us believe that unless we are doing the hard thing, we are not enough as people and worthy of good things. www.praf.me/it-used-to-b...

"Every line of AI-generated code is a plausible-looking liability." Great quote from this article mrkaran.dev/posts/ai-hom... by @mrkaran.bsky.social

Arrived in Switzerland for my next CERN delivery. Think this the first time I’ve arrived in daylight.

So good! I was looking for the dogs as it felt like something you would make.

This came up in my RSS feed today - this would have made teaching A-Level Maths much more fun. I kind of miss teaching linear algebra. little-book-of.github.io/linear-algeb...

✈️ Ever wondered what it’s really like to get flown around the world to teach developers? It’s not all airports and adventure — there’s also late-night prep, receipts, and managing energy after long days in the classroom. New video: youtu.be/sCJDePAUL9Y Would you want to teach internationally?

AI can already write lessons, quizzes, even full courses. So… do we still need teachers? 👀 I explore that question here: youtu.be/3CuqbqEAp-w What do you think — will teachers be replaced, or is the role just evolving?

Before I teach a single thing, I always start with the same 3 questions. They set the tone, build trust, and often save the whole course. Here’s the video: youtu.be/Xsuf0KIEu5g What’s the first question you ask when leading a group?

Recently delivered a client Statamic project. Trying to work out if it would be interesting to pull together all the things I learnt through the build.

Disappointed that Kevin McCloud from Grand Designs is not Kevin MacCloud the composer of lots of TikTok background music. Lost a bet about it.

Continuing my map theme - here's an atlas of space atlasof.space very cool!

Who doesn't love a map? Here's an energy dashboard for the UK www.energydashboard.co.uk/map

I love scrolly-telling articles and this one was great! pudding.cool/2025/06/hell... A study that paired random partners for 30 minutes of conversation - measuring people positive/negative feelings at various points of the conversation. I love 30 min conversations with new friends - hit me up!

Got a DJI Mic Mini so I could improve my audio quality in future videos. Course recordings are normally at my desk with my lovely Shure mic but talking heads were harder. It wasn't working. Very confused. Turns out I was plugging it into the headphone jack not the mic jack! Doh!

Think I’m going to create a bit more content around being a developer educator. My first attempt is to argue that every course should begin from an empty page even if you have taught it a lot before. *Always* start with a blank page youtu.be/ombhvp2OdEA

Really interesting post from @hazelweakly.me about working with AI tooling in a way that aligns with how we learn and think as humans. hazelweakly.me/blog/stop-bu... ht/ @spavel.bsky.social most recent post.

I scored 19/21 on e-mail.wtf and all I got was this lousy text to share on social media.

You know that stage of a client project where it’s pretty much done but it also never seems to be done … I do. Too well.

I really enjoy working with Claude code. Tried doing API pay as you go and it clocked up fast, upgraded to Pro and I keep hitting usage limit, trying to decide if I can justify Max as a solo dev. With a Claude, ChatGPT and Cursor subscriptions and I'm feeling bled dry by AI companies.

Planning a one shot for my D&D group - our DM is overwhelmed and I’m picking up the reins. Going to do a Blades in the Dark inspired heist game. Imagine Ocean’s 11 but we start in the middle of the heist-every time we hit an obstacle there’s a flashback to explain how someone prepared for it.

It might just be my reluctance for change but I'm not enjoying GPT-5 and miss 4o and o3.

Last week, I stole a classic classroom move for a corporate AI ethics session: think->pair->share. A prompt for individuals to think about (90s), pair with someone next to them to discuss (3 min) and then share with the group. Zero grandstanding, lots of voices. Best conversations of the day.

My kid is doing a Python summer camp and asked me to look at the code he’d written for a text adventure game. Couldn’t help saying “yuck” when I saw he was using the global keyword. Other than that it was looking good

Hacked Claude Code to see what it does. It's kinda funny. mariozechner.at/posts/2025-0...

Off to Birmingham to deliver a workshop on AI for consulting professionals. Slightly worried about mutant rats.
