At the moment, it is not possible to sell a 2nd hand eBook or MP3. This seems fairly reasonable because a re-seller might keep copies of their original files after selling them. This would allow the re-seller to undercut the original publisher and sell the file multiple times. We tend to label this "Piracy". Someone buys a DVD, rips it, then either sells or gives away copies. The Blockchain…

As previously discussed, I'm doing the Certified Blockchain Professional course. It is self-directed learning, so I'm going through it at my own pace. In order to consolidate my learning, and help organise my thoughts, I'm blogging about my reflections on each module. These are mostly notes to myself - but I hope if you find something interesting (or incorrect) that you'll leave a comment. Part …

Sometimes - only sometimes - slowness is a feature, not a bug. A few weeks ago, I was reading about a purported use for "smart contracts". If your plane is cancelled, a smart-contract could automatically pay out your travel insurance, the millisecond the cancellation was reported. Nifty, right‽ Slowness for crap reasons There are plenty of processes which are slow for annoying reasons. The i…

Here's a (possibly) daft idea. What if you could pay for goods using a transferable bank account? Say you want to pay a friend some money. But you're not physically close enough to hand over cash. You create a new bank account with a unique username and password. As quickly and easily as getting a new email address. Couple of clicks and it is done. You move money from your main account into…

Why do I do this to myself? Why? As part of my ongoing MSc, I have to take 3 professional training courses. I've completed my cybersecurity course, and I have a Machine Learning course booked for January. So what to do next? There's a lot of discussion in government circles about Blockchain. As with any new tech, there are plenty of Thought Leaders™ and sales drones trying to push it. For e…

You've heard of the AI Winter, right? The period where funding for AI dried up due to products failing to meet their hype. I think we're now in Springtime For Crypto - named after the musical "Springtime for Hitler" from movie The Producers - where scams abound. You should take a couple of hours to watch The Producers. Either the 1967 classic movie, or the 2005 remake will do. The pivotal…

Kevin Kelly has written an insightful blog post about Class 1 / Class 2 Problems. I encourage you to read it. I agree with the thesis, but not the specific conclusion. Blockchain tech could unleash collaborations of several million members working on one project in real time, or orgs that are far more leaderless than today. How? Projects like the Linux Kernel already have thousands of…

I blog about my solar panels - probably a bit too much! Recently, a reader asked me if I'd heard of Rowan Energy's solar payback scheme - so I took a look into it. Here's how it works: Rowan installer a "miner" next to your solar inverter (the big box that turns DC from solar panels into AC for home use). The "miner" monitors how much electricity you produce and reports it back via your home…

Way back in the early days of the Social Web, the writer Cory Doctorow invented Whuffie. Think of it as a way to formalise "upvotes" and "likes" on social media. Whuffie, a form of digital social reputation, replaces money and is a constantly updated rating that measures how much esteem and respect other people have for a person. This rating system determines who gets the few scarce items, like …

(A hastily written and grumpy post.) Another day, another Blockchain Bullshit project. Someone "claimed" one of my Tweets and added it to the Blockchain. I'm not particularly happy about that. Nor am I happy with the hoops I had to jump through to contact the company and remove my work. You can read the whole sorry thread on Twitter. But, mostly, I'm unhappy with this whole scammy…

In the early days of the web, I used to go hunting for Beatles Bootlegs. I scoured forums, emailed dodgy geezers, and swapped poorly encoded RealAudio™ files on USENET. The Beatles had recently released their Anthology series, and us nerds were desperate to hear more unreleased goodies. Sure, there were rarities and out-takes, but we wanted more. We wanted Ultra Rare tracks. That one song no o…
