Why does it seem like the smarter something is, the more easily it can be taken down by unexpected stupidity? In this case, machine learning models that are smart enough to “read” handwritten words and recognise them as references to an object mistakenly assume that the word is the object. The end result? Sticking a handwritten label on any image scanned by this system will cause it to report that its “seeing” whatever is written on the label instead.

From technical stupidity to natural eccentricity: these sea slugs can decapitate themselves and then regrow their entire body including all of their internal organs. One reason why might be medical; the researchers guess that the sea slugs might use this feature to ditch their old body if it gets infected by parasites, so that they can grow a healthy one back. But how do they survive without any internal organs? By borrowing the chloroplast cells that control photosynthesis inside their favourite food, algae, and powering themselves with the sugars produced when the chloroplasts photosynthesise.

Now, heading back to technical errors… https://getpocket.com/read/3284812993

This is a good lesson about how the bad software design, and more importantly the bad user interface design, that forces people to regularly rely on clunky workarounds is a recipe for problems. It always amazes me when I hear about large-scale errors that ultimately happen because the software required to do the job was incorrect, unintuitive, or poorly-designed. That’s especially true for institutions as large and as impactful as banks, where any error could result in millions of pounds being lost or mislaid – surely they can afford to spend money making the software that earns their wealth as usable and efficient for the employees using it as possible?

I also finished reading Toksvig’s Almanac, and posted a review.

On more book-themed news, I was introduced to Standard Ebooks.This is a volunteer-run project that takes existing public-domain ebooks from places like Project Gutenberg and gives them a makeover; from typesetting and formatting, to finding high-quality public domain artwork, to coding the books in an open-source format with version control to make them reliable and standardised. Its a really cool example of using technology to safeguard and support literature, rather than to lock it down.


This week, I started replaying the campaign of Grand Theft Auto V. While I did play through the campaign on Xbox 360 shortly after its release in 2013, I played through it in a very fragmented way that means I missed a lot of the side-quests and story details. As a result, I’ve often wanted to return to it and play the story “properly”, and see more of the details and events in the sprawling world of Los Santos.

I also revisited the online aspect, which I haven’t touched for years. As many missions can’t be played solo, I’ve barely played any of the “storyline” of the online aspect. I spent time yesterday doing smaller side-events that can be done solo, which was surprisingly enjoyable… well, until I made an enemy of two other players who then kept repeatedly killing me every time I respawned, which meant that I didn’t have enough time to go into the pause menu and choose any options that could have removed me from the situation. As a result, the only thing I could do to get away from this was to leave the game, which was annoying.

Aside from that, I’ve also returned to Two Point Hospital and started a new save file to try and relearn the strategies to take on the harder levels.


A few days ago I bought my (virtual) ticket for this years OER conference. The only time I’ve actually been is 2017, when I presented my MSc research, but the effect that 2020 had on education and educational technology, as well as things like ebooksos, have brought my attention back to the tireless work of the open community. Like last time, I’m sure that I’ll finish listening to the talks and realise that everything I know is a tiny drop in the education ocean!
