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.

ColinWright··on They are looting your life savings
Suffering the HN Hug of Death.

Text reads:

And just like that—surprise!—one AI company bails out another AI company's grift. Google agreeing to rent compute from xAI (cough, "SpaceX") magically makes them eligible for inclusion in the S&P500.

Americans, they are looting your life savings, the ones you earned through labour that they are gleefully replacing. Your descendants will never have the chance you had.

ColinWright··on Ask HN: How did you discover Hacker News?
I drew a graph of connections between Paul Graham essays, and coloured them via a PageRank-style weighting algorithm. I emailed it to PG, and he suggested I post it here.
ColinWright··on Don't Build Your Own Lisp
Is it too much to ask that when giving a book review, a link to the actual book title, and possibly a listing on a website, should be prominently given?
ColinWright··on In the Matter of an Office-Holder and in the Matter of the Insolvency Act 1986
33:

Lawyer A began chatting with the firm's AI on 20th March 2026 following receipt of my query of that date.

What is remarkable when reading those chats is, first, that one would think that the text attributed to the AI was produced by an intelligent human being.

The second remarkable thing is that, on a large number of occasions, it is plainly wrong or, at the very least, extremely misleading.

ColinWright··on A HN post with negative points – how?
I think you are mistaken.

FWIW: I have over 135K karma and I can't downvote submissions.

ColinWright··on 'AI gave me your number': AI doxxing turns ChatGPT hallucinations to harassment
I had trouble reading the web site ... I'm sure someone can provide a link to an archive or something.

Meanwhile, I used "lynx -dump" and lightly edited the result, so the plain text is here:

ColinWright··on I'm 16 and I built FutuRole to fight the "humiliation ritual" of job hunting
I agree entirely that seeing and experiencing are different, but seeing it is more than being blissfully unaware, and can be enough to provide motivation.

And I've worked with many youngsters who have significant amounts of empathy. They feel the pain almost as if it's their own.

>> definitely matters as to how old they are, and how much they've done.

> No, it doesn't. Either the tool is good/useful or it isn't.

So if a developer with decades of experience in writing software would receive exactly the same feedback from you as a 16-year-old writing their first project?

If not, if you would tailor your feedback, then it does matter how old they are.

ColinWright··on I'm 16 and I built FutuRole to fight the "humiliation ritual" of job hunting
I know 16-year-olds, and 15-year-olds, and 14-year-olds, who absolutely know what goes on in a job hunt because they are observant, socially aware, and have watched relatives sending literally hundreds of resumes and get nothing back.

And those kids ... inexperienced, no mortgage, no creditors, no "real world" responsibilities ... absolutely see it.

When someone builds something using the tools at hand and the experience they have, it definitely matters as to how old they are, and how much they've done. That shapes how you give feedback, both in style and content.

I know a lot of bright, intelligent, keen, motivated kids, and in every way I encourage them to go and build things that they think are relevant and important, even if I don't agree. The experience will shape them and make them better.

ColinWright··on Can anyone point me to a ShowHN first post policy documentation?
That's not telling me what the message is that HN is giving you when you try to submit the project.

ColinWright··on Considering a Sphere
In case anyone else is as baffled as I was by this comment, I did a quick web search and found this:

Pondering the orb refers to a meme that features a sagely figure looking into a crystal ball, often used humorously in various edits and templates online. It originated from a Twitter post in October 2021 and has since become popular across social media.

I knew nothing of this. Maybe I'll put the post up under that title and set the linked page to be a re-direct.

ColinWright··on Isaac Asimov: The Last Question (1956)
Thank you ...
ColinWright··on Juggling by Numbers
One of the top comments on the Youtube version:

> This video was surprisingly interesting.

ColinWright··on Most people can't juggle one ball
People say "Practice makes perfect" ... they're wrong.

Practice make permanent.

You need to practise the right thing, and that's where you will benefit from good quality feedback.

Learning on your own is hard.

ColinWright··on The Feeling of Power – Isaac Asimov
I don't know why the HTML versions all seem to lose the section breaks ... they're easy enough to render.

Never mind.

ColinWright··on The Feeling of Power – Isaac Asimov
I remember reading this in the late-60s, and it's very much an old friend. It does, however, annoy me when the section breaks are lost.

Here's a PDF:

Also, it's no surprise that it's been submitted many times before. Here's one of the earlier discussions:

Even so, perhaps there are new things to say in this time of emerging "AI-assisted programming".

ColinWright··on Point Cloud Allemansrätten
Up for me ... now.

I'm in the UK, and it's four hours since you asked. I suspect it's suffering the occasional HN "Hug of Death".

ColinWright··on Show HN: Made a little Artemis II tracker
Absolutely ... https://issinfo.net/artemis is the one I use.

Great sense of scale, lovely to see the Moon apparently a long way from the "intercept" point, and it seems "accurate enough".

Closed.

ColinWright··on Six Math Essentials
I find Stillwell's writings to be exceptionally clear and accessible, and I recommend them.

It will be interesting to see if Tao's writings are as clear, though possibly he is targetting a different audience.

ColinWright··on I verified my LinkedIn identity. Here's what I handed over
This seems to be exactly the opposite of what I was describing.

While I had a LinkedIn account I was not receiving spam.

When I deleted my account, the spam started, and continues to this day.(+)

(+) Which is not a surprise ... once an email address has been leaked it gets onto lists and the spam will never end.

ColinWright··on I verified my LinkedIn identity. Here's what I handed over
I used to have a LinkedIn account, a long time ago. To register I created an email address that was unique to LinkedIn, and pretty much unguessable ... certainly not amenable to a dictionary attack.

I ended up deciding that I was getting no value from the account, and I heard unpleasant things about the company, so I deleted the account.

Within hours I started to get spam to that unique email address.

It would be interesting to run a semi-controlled experiment to test whether this was a fluke, or if they leaked, sold, or otherwise lost control of my data. But absolutely I will not trust them with anything I want to keep private.

I do not trust LinkedIn to keep my data secure ... I believe they sold it.

ColinWright··on Watching an elderly relative trying to use the modern web
Trying to pay a bill. On the website ... it took 24 minutes to navigate to the right place. Then they needed 2FA, so they emailed it to her.

Now she's supposed to open her email while keeping the web page open. It took 5 minutes to do that, find the email, copy down the code, close the email ...

Web site has timed out.

Just one of many examples.

Looking at the front page now and I cannot see it. Do you have a link?

(pause)

Ah, now on the second page ...

Thanks for letting me know.

ColinWright··on Tao: An experiment reviving an archaic practice from the era of Gauss
This is a fascinating experiment! I've just been reading the first few paragraphs of the paper ... easily readable, intended to be accessible by anyone.

In Gauss's time mathematicians would solve problems, publish the solutions in an encrypted form, and then challenge their contemporaries to solve the problems.

Here the authors of a paper on the arXiv say:

"To assess the ability of current AI systems to correctly answer research-level mathematics questions, we share a set of ten math questions which have arisen naturally in the research process of the authors. The questions had not been shared publicly until now; the answers are known to the authors of the questions but will remain encrypted for a short time."

Tao says:

"... the challenge is to see whether 10 research-level problems (that arose in the course of the authors research) are amenable to modern AI tools within a fixed time period (until Feb 13).

"The problems appear to be out of reach of current "one-shot" AI prompts, but were solved by human domain experts, and would presumably a fair fraction would also be solvable by other domain experts equipped with AI tools. They are technical enough that a non-domain-expert would struggle to verify any AI-generated output on these problems, so it seems quite challenging to me to have such a non-expert solve any of these problems, but one could always be surprised."
