Refutation of Anyabike

Tags: Opinions

In my last post I detailed why an article for the Daily Mail was knowingly misleading in a number of ways. I mentioned a “few other idiots” and then said I couldn’t be bothered to deal with one of them. This is that one. Anyabike made a medium post which is now doing the rounds [1] – including an endorsement from Andrew Neil, who really should know better. It’s clearly wrong on some counts but I’ve seen it twice today so I’m following it up. I suggest you read it before continuing.

The Case of the Wreath and the Wrong Graves

Tags: Opinions

Addendum: In another piece, I’ve definitively shown that the monument I talk about in this piece is next to the graves, contradicting the Daily Mail statement that it is in “another part of the complex”.

The Daily Mail recently published yet another attack on Corbyn [1], accusing him of memorialising “Munich terrorists”. They say that, in response to this accusation, he “insisted” that he was there to commemorate the 1985 bombing of the PLO base in Tunis [2], but then show him pictured in front of the graves of those same “Munich terrorists”.

Quick Snippet: Slack Emoji Names to Unicode :smile:

Tags: Programming

While working on this blog, I wanted to add Slack-style named emoji.


Eventually, I realised Pandoc already has Slack emoji support 🎉, but only after I’d already made my own 🤦‍♀️. Then I found out Pandoc doesn’t seem to have :‌woman-facepalming:, so it’s a damn good thing I did 😳.


Backpropagation Refresher

Tags: Machine Learning, Notes

Sometimes when I write reports, I end up summarizing backpropagation, which spurs me to derive it again for myself. Backpropagation isn’t particularly complicated mathematically, but if you’re not super comfortable applying the chain rule until your arm falls off, or combining calculus and linear algebra, it might feel a bit involved. Especially when my calculus is rusty, I occasionally go down some less sensible routes and take a while to get there – hopefully, writing this down will prevent me going the wrong way again. This is something of a crash-course in the derivation, without any of the diagrams or other niceties necessary to make it even slightly intelligible.
