Hi, I'm Tom Scott. These are some of the things I've made and done. They'll probably come back to haunt me in a few years' time. (Want to get in touch about anything? Use the "contact me" link below, not YouTube messages!)
It's been all over the British news today: developer Paul Price found a bug in photo-crap-maker Moonpig's site, one that might have exposed three million users' personal information. Paul's got a great technical post about it at http://ifc0nfig.com/moonpig-vulnerability/ -- but there's no decent non-techie explanation except for the one-paragraph summaries in newspapers. It was a perfect storm of tech incompetence: here's how to avoid doing it yourself.
Your sports team wins. The confetti drops. And suddenly, the video quality falls apart. Why? Let's talk about interframe compression, bitrate, and unnecessary green screen effects.

http://tomscott.com - http://twitter.com/tomscott - In the news today: a link which, when moused over or clicked on, crashes Google Chrome. It's a heck of a bug: but how does it work, and what does it have to do with "null-terminated strings"? TECH DETAILS: https://code.google.com/p/chromium/issues/detail?id=533361
http://tomscott.com - @tomscott - There are lots of interesting features in other languages, some of which English would really benefit from having. I'm going to talk about four of them: time-independence, clusivity, absolute direction, and evidentiality. Also, I've learned from last week: no irritating piano music this time!

At Autodesk's Pier 9 workshop in San Francisco -- and no, this isn't an ad, pull down the description for more! -- there are giant robot arms using welders to 3D print with stainless steel. Which seemed like a good place to talk about programming abstractions, high-level languages, training pendants, and just how safe something like a robot arm needs to be. FULL DISCLOSURE: Autodesk were good enough to cover my travel to San Francisco, but they haven't paid me and they had no control over the script, the content or the final cut!

http://tomscott.com - http://twitter.com/tomscott - ALL THE ELECTRICS I USED WERE UNPLUGGED. DO NOT DO THIS. Yep, I'm going all patriotic again. And while I'm willing to bet that a good number of British folks know the first half of this video, there's one thing about slack in here that I only just learned myself.

YouTuber Tom Scott has flown drones through lightning, he’s taken on the first human-powered theme park, he’s even visited Penistone. But he’s never taken on a British Museum curator in the world’s oldest playable board game… UNTIL NOW! For International Tabletop Day 2017, Tom Scott was challenged by British Museum Curator Irving Finkel to a round of the oldest playable board game in the world – The Royal Game of Ur – a game whose rules were rediscovered and deciphered by Irving himself. Interested in other mysterious cuneiform tablets deciphered by Irving? Check out his book 'The Ark before Noah' to find...

http://tomscott.com - http://twitter.com/tomscott - It should never have happened. Defending against cross-site scripting (XSS) attacks is Web Security 101. And yet, today, there was a self-retweeting tweet that hit a heck of a lot of people - anyone using Tweetdeck, Twitter's "professional" client. How did it work? Time to break down the code. (Remember the old Myspace worms? They worked the same way.) THE SELF-RETWEETING TWEET: https://twitter.com/derGeruhn/status/476764918763749376
In the URL of each YouTube video is the 11-character video ID, unique for each video. Can they ever run out? Just how many videos can YouTube handle?

This is a collaboration with the Royal Institution! Go check out their video here: https://youtu.be/sScrtGdKmho -- Perpetual motion machines are badly named. And impossible. But that hasn't stopped a lot of people trying to build them. Sure, you could try and argue physics: but there's a more common-sense reason why free energy's not coming any time soon.

Inuktitut syllabics are brilliant. A writing system that's not an alphabet, but something really clever: an abugida, one designed from scratch for a language very unlike anything European.
