Hot new social networking site BlueSky has an interesting approach to usernames. Rather than just being @example you can verify your domain name and be @example.com! Isn't that exciting? Some people are @whatever.tld and others are @cool.subdomain.funny.lol.fwd.boring.tld I wanted to know what the distribution is of these domain names. For example, are there more .uk users than .org users? Shut up and show me the results You can play with the interactive data Oh, and the large number of…

A few weeks ago I was moaning about there being no OpenBanking API for personal use. Thankfully, I was wrong! As pointed out by Dave a company called Nordigen was set up to provide a free Open Banking service. It was quickly bought by GoCardless who said: We believe access to open banking data should be free. We can now offer it at scale to anyone - developers, partners and Fintechs - looking to solve customer problems. And, I'm delighted to report, it works! As a solo developer you can…

A few months ago, I had a lovely rambly chat with Harry Keir Hughes about the nature of data, transparency, and how it can tie into the Net Zero agenda. Harry and his team have taken my pontifications and placed them in the very swanky Digital Radar Report. The full report quotes lots of people - not just me! - and is mostly about "Live data" i.e. data that is transparent, readily accessible, and shared widely – is a prerequisite for innovative, sustainable, and human-centric enterprises. …

How do you fairly split a country into electoral subdivisions? This is a difficult problem. Whatever you choose, you'll piss off someone. A politician will be annoyed that their loyal voters are no longer in their district. And voters will be annoyed that they're now lumped in with people from the wrong side of the tracks. This is a very human problem. So let's ignore all the human aspects and run an impartial and unbiased algorithm on the issue! The Splitline Algorithm is, conceptually,…

Every so often, an employer asks me to help make a dashboard. Usually, this causes technologists to roll their eyes. They have a vision of a CEO grandly staring at a giant projection screen, watching the pretty graphs go up and down, and making real-time decisions about Serious Business. Ugh! What a waste of time! The thing is - that's not what a dashboard is for. And that's generally not why a CEO wants it. A dashboard shows that you have access to your data. And that is a huge deal. If…

Here's an idea that can't possibly work. People used to pay-per-minute for telephone calls. Some numbers were "zero-rated". That is, if you called them you wouldn't be charged. At first it was calls to the emergency services which were free. Businesses and other organisations realised that it was good customer service to provide a free-to-call number. Generally speaking, this means that the called-party pays the phone company for incoming call rather than the caller paying. Thus 0800 numbers…

I am very interested in your opinion on this. Imagine that you work at a company which sells widgets. Each widget has a unique serial number. The number is a fixed length, and can contain leading zeros. That is, the following are all valid identifiers: 00001 01010 12345 What data type would you use to store these data in a database? This is one of those strong opinions, weakly held. I'm not sure there's a right answer to it. A quick survey on Twitter was inconclusive: Terence Eden is…

Previously on Terence Eden's blog... About 4 years ago, I wrote about Visualising Twitter Conversations in 2D Space. Based on an idea by Lucy Pepper, I built a quick hack to show what Twitter threads actually looked like. Well, lockdown finally got the best of me, and I finished the project! TweeView.ml Here are a few screenshots of "interesting" trees, and a little bit about how it works. In this example, the user has a main thread that they are posting on: You can see that a few people…

Here's set of visualisation I've been working on. Last night, at #TapIntoTwitter, I demonstrated a fun way to view your Twitter conversations as a force-directed graph in 3D space. I'm going to show it off to you, then explain how it works. This is a designed as a "fun" demo. Here we go! So, what's going on? As I've previously blogged about, Twitter has a new conversations API. That allows you to get Tweet replies in a tree-like structure. A small conversation looks something like this: …

I'm doing an apprenticeship MSc in Digital Technology. In the spirit of openness, I'm blogging my research and my assignments. This is my paper from the Data Analytics module. I enjoyed it far more than the previous module. This was my second assignment, and I was amazed to score 72%. In the English system 50% is a pass, 60% is a commendation, 70% is distinction. Nice! A few disclaimers: I don't claim it to be brilliant. I am not very good at academic-style writing. I was marked down for…

I want to buy a big chunk of data and use it until it runs out. I'm not interested in a contract. I don't want a bundle of phone calls, SMS, or ringtones. Just give me DATA that lasts for as long as possible. Here's the best data deals that I could find. Stick them in your 2nd SIM slot, use them as broadband backup, or shove in a dongle and attach to a Raspberry Pi. Operator Cost Data Length £/GB £/Month Link EE £50 120GB 12 Months £0.42 £4.17 Amazon O2 …
