You're correct, the horizontal and vertical flips for the square, are already accounted for in the wreath product. And I miscounted the products themselves. Up to 1.2*10^12 symmetr…

The exponential number of symmetries present in sudoku problems, means that once you've found one valid instance, you've actually found up to 9! * 3!^4 * 8 which are exactly the sa…

You can use the waybackmachine. This works for Worldle as well. http://web.archive.org/web/20231127182010/https://imois.in/g...

Wait, But Why? has a fascinating series of posts on this. https://waitbutwhy.com/2013/10/why-procrastinators-procrasti... I bought the 52x90 poster where each square is a week of y…

When I worked at Skyscanner, we'd volunteer at events where high school kids would be shown tech stuff. We'd setup Raspberry Pis with Minecraft on them and show them some basics of…

Only US citizens are permitted to deploy code to the US government production servers, or look at the telemetry from those servers. (I'm a UK citizen, based in the UK, and I have l…

The pandemic is ongoing, but despite its lasting impacts e.g. hybrid or remote is the norm, many things are back to normal. One thousand days out, how are things for you?

I created a CloudFormation script specifically to do this (including CloudFront for CDN). Yes, there's reasonable complexity, but it's a trade-off of security and configuration. As…

Budget: how many are working on the project? Features: what should the project do? Timeliness: when do you want the project done? You get to choose only two.

You're correct, yes, I didn't realise how generous the free tier is. If you're doing fewer than 500 updates per month, Cloudflare looks good https://pages.cloudflare.com/ Because I…

Familiarity with S3, Route53, and CloudFront was a draw for me personally. AWS is all about abstractions. Some of them are worth learning but increasingly there's a wall of options…

Nothing particularly novel but the setup of configuring CloudFront to connect to S3 and handle SSL termination, a DNS record pointing to CloudFront, an S3 bucket to hold the conten…

Cloudflare Pages looks like a more productionised version of this, yes. In terms of advantages, I'd say price, and the maturity of using AWS. I deploy a static site with a GitHub A…

Completing a PhD is risky. I'd recommend reading this to see some of the ways it can go wrong: https://100rsns.blogspot.com/ Ultimately it's a big commitment. Speak to as many peop…

I agree with you, those are absolutely fundamental. The bar should be set higher though, especially for senior engineers. https://benjiweber.co.uk/blog/2021/04/10/dont-hire-top-tal…

I'm an engineering manager in my 40s and I've hired engineers older than me. I appreciate you're absolutely correct, age discrimination does happen. One thing to consider for older…
