This is a blog post about user interfaces. I was wandering along the beach one day, when I noticed some clever chap had drawn some arrows in the sand. Can you guess where they led? The more astute of you will have realised that these are not human drawn arrows. They are, of course, footprints left by birds. A bird's foot is a "backwards" arrow. The apex points to the bird's rear. It is …

Companies face a complicated choice. Make things easy for the customers, or make things secure for them. Convenience seems to take priority most of the time. This forces companies to get their customers to risk their own security. In this example, we see Verizon Wireless asking their customers to type their passwords into Twitter for everyone to see! This is dangerous. It is likely that many …

I'm probably not the first to do this - but it was a fun way to learn just how tricky it is to control a cheap quadcopter even in mild weather. This video has no sound. Your browser doesn't support HTML5 video tag. Good enough quality to make sure the panels aren't covered in bird-mess, leaves, or anything else which might block their efficiency. Thanks to Jack Franklin for the…

Last week I attended a talk by Dr Irina Higgins from Artificial Intelligence company DeepMind. It was a fascinating look at how their AI works, and how it is trained. Terence Eden is on Mastodon@edentIf you've ever played a video game online, it is likely you've been training an Artificial Intelligence agent without realising it.Ethical?❤️ 7💬 4🔁 020:06 - Thu 09 March 2017 Part of the problem is…

Update! The source-code for this app can be found at https://github.com/edent/TweeView Many years ago, I created a threaded conversation viewer for fledgling social network App.net. It was a unique way to flow through a conversation without having to be constrained by the linear vertical scroll of the typical web browser. App.net died - and I never found a reasonable way to recreate it for…

Here's a simple bash one-liner to convert mixed-case filenames into Title Case: rename 's/(\S+)/\u\L$1/g' * This forces the file extension to lower-case as well. Use rename -n to test the command without changing anything on the filesystem. (Adapted from this PerlMonks FAQ.) Background I have a bunch of inconsistently named files like: HERE COMES THE SUN.mp3 hey jude.mp3 The lOng and…

Walking back from work yesterday, I noticed an unusual set of chuggers - those faux-cheerful folk who try to stop you in the street asking for money. They were fundraising for Unicef. Rather than handing out flyers they were carrying high-tech VR headsets! Using the headset, I was able to take a virtual tour of a Unicef aid drop. As with all 360 experiences, it takes a little getting used…

The ultra secure messaging app, Signal, requires a mobile phone number in order to sign up to it. This, as my friend Tom Morris, points out, is madness. People don't own mobile phone numbers. They are rented from mobile operators. Yes, you may be able to move "your" number between a limited set of providers - but it ultimately doesn't belong to you. An operator can unilaterally take your number…

Twitter has recently improved the accessibility of its site. When uploading an image, a user can add alt text - a short description of the image for people with visual impairments. Here's an example: Terence Eden is on Mastodon@edentThis is a test to see if alt-text in images is searchable on Twitter.alpaca omnithorp pic.x.com/jhgcsaxpkd❤️ 1💬 0🔁 010:37 - Sun 19 February 2017 If you take a look…

I've found an interesting, but low severity, way for a malicious user to selectively deny access to specific GitHub issues and Pull Requests. This doesn't affect the whole site - just targeted pages. It doesn't require elevated permissions, nor any special skills. This is just GitHub punching itself in the face. Here's how it works. An attacker creates thousands of comments in their own…

C-3P0 doesn't have a schnoz. The degloved terminator has a bleak hole where his snout should be. Both the Jetson's Rosie and Futurama's Bender are arhinotic. The robot sat in front of me was different. The RoboThespian is an imposing chunk of metal. LEDs blink as servomotors whine. The exposed wiring twists as the arms flex in a crude approximation of humanity. But the face... Oh! The face! A…

Is email dead? I don't think so - but I know lots of people who either don't have an email account or deliberately don't check it. And why should they? Is email a requirement for modern life? All the major chat apps - WhatsApp, Line, Signal, Wire, Skype - only require a mobile phone number. Hey presto I can communicate with anyone around the world. No email required. But, suppose I wish to…
