If you want to contact me, find me on the web. I am especially interested in math, juggling, programming, and education, and since there are other people with my name you'll probably need to include at least one of those terms in any search.

I was once a prolific contributor and commenter, but no more. I go through bouts of submitting stuff, but then go and disappear for lengths of time. If there is something you'd like me to see or comment on, you can email me. Don't ask me to upvote things. If it is interesting (to me) then I will.

Submissions do not imply endorsement.

My spam filtering is pretty severe, but I've put the word "Dysprosium" on the allow-list - quote that and your email will get through.

I used to have an email here but it got harvested by spammers - I'm looking at you, mbientlab.com - so it has been removed. This is a temporary one:

HN_a7dab8S4@solipsys.co.uk

Email sent there and quoting the element name will pass my spam filters. After that we can use "proper" email addresses.

I know Hannu, and he tells an interesting story about getting his first book published. I should write it up sometime ... in my Copious Free Time ...

This comment box is too small to contain the story.

* The Quantum Thief

* The Fractal Prince

* The Causal Angel

Actually, most of the story is on his WikiPedia page:

ColinWright··on Isaac Asimov's "Profession"
I've been reminded of this because of the recent discussion about the use of "AI" in mathematics. The protagonist complains about having to acquire knowledge in dribs and drabs, learning slowly and painfully, while everyone else gets the knowledge effectively "for free".

The Wikipedia article also says:

"The novella inspired a research paper investigating whether people would choose to take a magic learning pill to gain knowledge without 'manual' learning, finding that 57 of 58 participants would replace at least some of their learning experiences with a magic pill."

ColinWright··on I've factored the RSA keys of a Certificate Authority from the 90s
Super ... thank you.
ColinWright··on I've factored the RSA keys of a Certificate Authority from the 90s
That's referring to attacking the factoring problem, which is one method of attacking RSA, and as I said is known to be faster than exponential, but it felt like the comment to which I was replying was talking about something other than just faster factoring.

I know there are other attacks on RSA, I was interested to know if the poster to whom I was replying knew of any others (other than factoring, which is kinda obvious). After all, I said:

> I know that factoring (which attacks RSA) is sub-exponential, ...

ColinWright··on I've factored the RSA keys of a Certificate Authority from the 90s
Can you point at some papers or articles that talk about attacks specifically on RSA? I've done a search and have a few references, but I'd be interested to know if you have any particular examples in mind.

I know that factoring (which attacks RSA) is sub-exponential, and I know that implementations of RSA (bad choices of primes, timing attacks, etc) can have weaknesses ... I'm just interested as to whether you have something else in mind.

Thx.

ColinWright··on “I just chose words carefully”
Although they are rarely read in monospace, I write all my emails in monospace, and frequently "choose my words carefully" to have the text left and right justified.

Every now and again someone notices.

I invite you to have a look at my profile ... I cheated once.

He was brilliant in "Oscar".

ColinWright··on Dolly Parton Has Died
I first saw the announcement here:

I submitted that, but it was DOA. I suspect the domain is on the HN block-list.

ColinWright··on The Generative AI Learning Penalty: Evidence from Chinese Secondary Education
Quoting from the abstract:

"AI adoption raises homework scores by 18% and reduces completion time by 30%, but lowers monthly exam scores by 20% within six months. High-stakes entrance-exam scores fall by 18 and 24%, with the full penalty emerging only after about two years."

ColinWright··on Finger: the 1971 social network that never died
I write like this sometimes, and I've come to deeply resent the fact that AI slop-machines mimic things that make some writers' style "suspect" or "AI smells".

The slop-machines write the way they do because they have been fed material, and they then spew that back out. So any writer whose style looks a little different, eccentric, or unique may find that the slop-machine's stochastic processes lead them into a state where the pool of possible continuations is small enough that the mimicry is strong.

My wife's writings have recently been labelled as "probably AI" ... and we are livid.

But there's nothing we can do except write in a style that is not truly our own, just to avoid the inaccurate "slop identification" algorithms from smearing us.

Vile machines.

ColinWright··on Toot.community is shutting down
The posts, when posted live on the host.

The user can download their posts.

When a host goes away, where do you propose the posts previously hosted there now get hosted?

One option is for the poster's new host to have all the old posts uploaded ... how then to previous other posts that point at them, or reply to them, get updated?

I'd genuinely be interested to hear your suggestions for how these technical issues could be resolved.

ColinWright··on Fibonacci's Real Mathematical Legacy
Quoting:

“Mathematician Laurence Sigler had made it his mission to translate [Fibonacci’s Liber Abaci], rushing to complete the task right before he died of lymphocytic leukemia in 1997. But his editor moved on, and the manuscript languished on floppy disks for years. For a while Sigler’s widow Judith Sigler Fell, fearing the project would be killed, took the extraordinary step of impersonating her husband in communiqués.

By the time Fell found a new publisher, Springer Verlag (now part of the same publisher as Nature), floppy disks had been superseded and she had to hire a hacker to extract the files. Fell then discovered that Springer only accepted submissions in TEX format, the technical standard for physics and mathematics texts. She learned it and spent six months retyping the text. Fibonacci’s Liber Abaci was finally published in 2002 — the 800th anniversary of the book’s first appearance.”

In my circles, "lol" means "laugh out loud" ... but I can see no reason why you would react in that way to this article.

Am I missing something? Can you explain or expand on that comment?

ColinWright··on Springer Nature has removed two studies by Max Planck
Quoting from the article:

Representatives from Springer Nature declined to comment, beyond saying that “detailed information about specific retractions is usually confidential and can only be shared with the relevant authors.”

So the only person with whom Springer can discuss why the papers have been withdrawn is ... Plank.

Well ... good luck with that.

ColinWright··on They are looting your life savings
No idea. Sometime when it's not being hammered you can ask them ... it's not my instance.

And I don't know what my instance is running on ... I have a tech co-mod who deals with it. We have two rather grunty servers running the the cloud, that's all I know.

If you're genuinely interested, email me and I'll find out for you. Details in my profile.

From their "about" page:

Hello World! Welcome to mastodon@bauhaus, our small niche in the fediverse.

This server originated @maschinenraum, a small hackspace in Weimar. It is currently administrated and moderated by a small team via @admin.

We run our own server in a local data centre just down the road, so there's no cloud here – however, that also means if it breaks, it breaks. And it will happen every now and then, and there are backups, and it's mostly fine, but don't expect 100% uptime – 99% will have to do.

We're part of the Chaos family surrounding the Chaos Computer Club, so you can meet us at events like the C3 and get to know your admins!
