ccppurcell··on Mike Mageek is dead
Might be a British thing (assuming you're not?) in magazines with a tongue-in-cheek character. For example Private Eye always refer to "the Grauniad" and "Carter-Fuck"
ccppurcell··on Cryptographic Right Answers: Post Quantum Edition
As I understand it, the only reason pqc is of "practical" concern is the issue of "store now, decrypt later".

Is it possible to defend against this attack in a classical way? Some sort of time limit on decryption? Or an argument that it's impossible?

ccppurcell··on Scrum is the Symptom, not the Problem
Seize the means of production comrades.
ccppurcell··on A Swiss town banned billboards. Zurich, Bern may soon follow
Something can be a cancer in modern times and have existed long ago. For example: cancer.
ccppurcell··on End Poem by Julian Gough
The inconsistent use of pronouns (it Vs them) and asking for the player's name but then almost exclusively referring to "the player" spoiled it for me a bit. But I liked the overall idea.
ccppurcell··on How I turned seemingly 'failed' experiments into a successful PhD
That's sad. That makes your piece of paper worth even less, in my opinion. How is that different from a degree mill. By the way I have my piece of paper but what I value (and what my colleagues value) is my understanding
ccppurcell··on How I turned seemingly 'failed' experiments into a successful PhD
Someone should sit every new PhD student down and explain to them that the goal isn't (or shouldn't be) getting publications or making an impact or getting a credential or a job. Of course you have to keep an eye on those things for practical reasons, but you can't lose sight of the goal which is to improve your understanding. Not even "our" understanding, just your own. If you pursue that and have a bit of talent (and luck) you will eventually push your understanding past that of the community on a given topic and you will write it up so that they may improve their understanding by reading your work.
ccppurcell··on Watching "Grizzly Man" with a bear biologist
If it's black fight back, if it's brown lie down, if it's white say goodnight.
ccppurcell··on Overleaf: An open-source online real-time collaborative LaTeX editor
I was just about to comment something like: worked fine for me... But then I realised that the only time I did this I was 6+ timezones away from my collaborators.
ccppurcell··on Frame.work laptop now available in Denmark, Finland, and Sweden
Different layouts have different size return keys, for instance.
ccppurcell··on Rosser's Theorem via Turing Machines (2011)
There is the textbook by Papadimitriou, I don't have a copy but I once taught a class that had been based on that book and slightly updated to include elements from Arora Barak. I think it's still a jump up from Sipser but perhaps a little gentler than AB. Ymmv
ccppurcell··on Rosser's Theorem via Turing Machines (2011)
The next step book wise is Arora and Barak, Computational Complexity: a modern approach. Of course that book is already out of date. The breakthrough that comes to mind is Ryan Williams' circuit lower bounds. He wrote a nice explanation of the proof here: https://arxiv.org/abs/1111.1261 He defines all the key terms pretty well but probably requires a bit of "maturity" to understand. There are also various breakthroughs to do with interactive proofs.
ccppurcell··on Japan Passes Law to Allow Third-Party App Stores on the iPhone
This is probably a very stupid question, but could GitHub claim to be, in effect, an app store, and force side loading? Not saying they would do that...
ccppurcell··on Effect of passenger position on crash injury risk in aircraft (2015) [pdf]
Casual readers will want page 3 for a description of the different positions and page 17 for a discussion of the results. The tldr is that the best seems to be: head against the seat in front of you, arms down by the lower legs.

The fact that any brace position won't help in a head on collision and the foolish inference that it is therefore at best pointless and at worst some kind of ghoulish conspiracy (to maintain dental records, to ensure quick deaths yada yada) is a real bugbear of mine. Same goes for the criticism of "hide under a table during a nuclear attack". With any catastrophe, there are unavoidable deaths from the initial impact and loads of avoidable deaths and injuries from falling debris, glass shards, smoke inhalation etc. These measures are about the latter.

ccppurcell··on What makes gambling wrong but insurance right? (2017)
This article is really interesting and explains the common origins of gambling and insurance, I had no idea that Lloyds of London began as essentially a gambling ring (and before that a coffee shop, another fascinating topic in the history of London and Paris especially and the world in general). Also a great line about governments being little more than mutual aid societies.

The comments here are a big let down. Just people opining glibly on the title. I hoped for better.

ccppurcell··on An Interview with Lola De La Mata about tinnitus
Here's something I did to slightly improve things. Buy one of those timed switches that are usually for outdoor lighting and things like that, and use it to switch the fridge off automatically during periods you need quiet the most. Obviously not too much of the day, use good judgement. Fridges are only working (and whining) when the temperature inside rises above a certain amount. With the timer you can have a little influence over when that happens.

Pray for me as I am stuck in an apartment building with a regular 50hz hum for the foreseeable.

ccppurcell··on McDonald's Loses 'Big Mac' Trademark in European Union
I think we nerds often fall into the trap of thinking that there must be some meta law that says "laws must treat similar things similarly" but there's no such provision in the law of any land that I know of. You're right that your analogous case seems implausible. It's irrelevant though.
ccppurcell··on McDonald's Loses 'Big Mac' Trademark in European Union
Even the description is practically word for word! Some time before I was born there was a promotion whereby saying "two all beef patties... on a sesame seed bun" in under a certain time got you a free big Mac.
ccppurcell··on You'll regret using natural keys
Here in Czech republic, everyone has an id number (rodné číslo) but as a foreigner, I have multiple id numbers. Further complicating matters, I was given a rč with the wrong gender (the gender is encoded in the number) and my nationality was at some point incorrectly listed as "Ireland". I do wonder if the Czech government thinks I am just two completely different people.
ccppurcell··on Geometry for Entertainment (1950)
The translation is really bad. The very first paragraph is practically nonsensical. There are several sentences that are either badly wrong or maybe russian idioms translated directly. Machine translation is ok for a rough idea but it's not good enough to put out in the world and call a translation.
ccppurcell··on Building an AI game studio: what we've learned so far
Question: the demo uses star wars imagery, including X wings and tie fighters, going as far as naming BB-8. How are you not getting sued to kingdom come?
ccppurcell··on Mathematicians and the Selection Task (2004)
I think it's given that there is a letter on one side and a number on the other side if every card and implicitly, that that rule hasn't been broken, otherwise you have to check every card to see that there's no emoji there
ccppurcell··on I don't want to spend my one precious life dealing with Google's AI search
I guess we are going to need something like ublock for AI content.

Tom Scott has a nice video on Ogham: https://youtu.be/2yWWFLI5kFU?si=EQccsJo6zHcyB1RB
ccppurcell··on Pražský Orloj: Prague astronomical clock simulator. (2022)
The first day after the lockdowns here I went to Prague. It was amazing to see the clock and Charles bridge without the usual crowds of tourists.
ccppurcell··on The Time I Lied to the CTO and Saved the Day
This is not about lying but being, quite literally, economical with the truth.

Just as you don't spend all your money at once, don't tell your boss everything you've achieved at once. Or not always anyway. I had to write a monthly progress report for one recent job. I kept a document of headlines for this, and put only two or three into each report. I kept some back for rainier months. This also helped me discuss my "objectives" since I often could predict at least one thing I would achieve in the next few months.

ccppurcell··on Cold brew coffee in 3 minutes using acoustic cavitation
Pricing is not at all obtuse! Or no more than any other product on earth. It costs what people are willing to pay. Your estimation of the value takes into consideration what you believe (I'm not saying you're wrong) the costs to be, and good for you. But until people are unwilling to pay, the price will go up.

ccppurcell··on TfL's simple pop-up message led to a significant drop in paper ticket sales
Back in 2014 (and possibly still, I no longer live in London) not only was it cheaper per ticket but it was capped per day, so you couldn't accidentally pay for more than the price of a one day ticket. Obviously this is much superior to buying paper tickets for each journey. But I remember having quite a hard time convincing visitors to use their contactless cards on the machines.
ccppurcell··on What can LLMs never do?
No, it's saying that I have general intelligence in part because I am able to reason about vague prompts
