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!)
http://tomscott.com - @tomscott - From tracking a point, to analysing pixels, to plotting 3D camera moves: here's how you go from shaky handheld shots to that "gliding through the Matrix" effect. Thanks to Matt Gray for his excellent camera work - he's at http://mattg.co.uk - @unnamedculprit
http://tomscott.com - http://twitter.com/tomscott - At dConstruct 2014, I spin a tale of the future: not to make a prediction, but to put our current world in perspective. Thanks to all the dConstruct folks at the Brighton Dome: crew, volunteers, and audience!
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
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. I'm at https://tomscott.com on Twitter at http://twitter.com/tomscott on Facebook at http://facebook.com/tomscott and on Instagram as @tomscottgo You might also like: How Green Screen Worked Before Computers: https://www.youtube.com/watch?v=msPCQgRPPjI This uses one Creative Commons by-attribution photo, "Sony Trinitron" by Antífama, available here: http://flic.kr/p/6DBMYn
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
Security of users' passwords should be at the forefront of every web developer's mind. Tom takes us through the insecure ways in which some websites deal with passwords. Note: At circa 8mins, the animation does not show how the 'salt' is also stored in the database alongside the username.

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? To work it out, we need to talk about counting systems, and about something called Base 64. Want to know how the single camera shot was done?

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!

Warning: Contains flashing images. You know those videos showing working perpetual motion machines? They’re fake. Tom Scott helps us explain how to debunk them. Watch his video here: https://youtu.be/EiZU3BvqvP4 Perpetual motion machines are tantalising. Videos of contraptions claiming to have achieved the impossible goal of endless free motion rack up millions of views on YouTube. But they’re not real. Perpetual motion machines violate the fundamental laws of our universe. In this video, we teamed up with YouTuber Tom Scott to provide three simple ways to debunk persistent claims of perpetual motion: a guide to protect you from the bunk. People have been...

It is now a vast network of roads carved into the sand for miles and miles with nothing but tumbleweeds and cacti to inhabit them. Tom Scott is a man on a mission to explore interesting places and share them with the world. He explains why this city didn’t grow to fill its vast scope, and how it has evolved over the years into the small, thriving and growing community...
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 - My talk from Ignite London 4 (http://ignitelondon.net): in which I rattle through the online privacy settings of fashionable web services, and leave a surprising message. FAQ: * Is the data really pulled in live from the web? With the exception of the Wikipedia articles, which I summarised in advance, yes. Everything on screen really was live data. * Did you know who was going to appear? No — but the selection process was algorithmic, not random. It was always going to pick someone interesting. As an extra safety net, a few minutes before I went on stage someone else checked who the system...
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.

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.
Tom spent a lot of time in Adobe After Effects to make that video, and for some reason, he chose to do a load of effects in this behind the scenes video too!

Who were the ancient Goths of Europe, and how did they go from conquerors of the Roman Empire, to the strange underground subculture we see today? Today we will discuss the history of the Ostrogoths, Visigoths, Vandals and other relevant groups from around this time period, and how they managed to dominate Europe, if only for the briefest of moments, only to fall into obscurity in only a matter of decades (or did they?) Please let me know your thoughts on the Goths as a nation, culture, kingdom and their influences on our modern societies today. Thanks for watching!

Last week I made a video surrounded by old-school CRT monitors and televisions - cathode ray tubes. And I completely forgot to remove the high pitched whine they produce. Here's why: why they make that noise, and why I didn't notice it.

It's not your imagination; hold music on phones really did sound better in the old days. Here's why, as we talk about old telephone exchanges and audio compression.
