It's a chart of a discussion on Twitter. I simply use two fingers on my trackpad and scroll back and forth, up and down, and explore the chart as it stands. If you can suggest an easier way to render it then I'd love to hear it.

Neat stuff ... it would be interesting to see a minimal "Tree of Concepts" to get one from school arithmetic to an understanding of this.

it would be! meanwhile, here's a bare sketch of the prerequisites needed to understand the theorem statement (the proof needs some more):

1. elementary algebra (functions, graphs, etc)

2.1. single variable calculus (limits, derivatives, integrals, series)

2.2. elementary number theory (modular arithmetic, euler's and fermat's theorem, etc)

3. abstract algebra (groups, rings, fields, and homomorphisms between them), abstract alg. also clarifies a bunch of elementary number theory.

4. the very basics of algebraic number theory (ideal class group, discriminant of number fields)

it may seem like a lot (especially to a school child who just learned arithmetic!) and in some sense it certainly is, but many of these concepts reinforce and build upon each other, so when you've understood them, it doesn't seem like much at all.

ah, i just checked out your profile and realised you have a PhD in math...my apologies for misinterpreting your original comment :p

I couldn't help but notice that you've created a fork of Gwern's website. That's so cool! It seems to be an independent implementation too.

I wanted to invite you to come say hello in #lesswrong on freenode sometime, or to DM me on twitter: https://twitter.com/theshawwn

What caught my attention about your site is that I know from experience how hard it is to create a fork of gwern.net: https://www.shawwn.com/swarm I noticed lots of little details in yours, like the fact that the anonymous feedback form is different, and that you exported your logo with potrace. (Killer logo by the way!) All of that took a lot of thought and effort, and it was a delightful surprise to see that someone else did it independently. It'd be neat to compare notes with you!

Thanks a lot for the thoughtful content, and the tree of concepts. I don't have nearly as much training in math, so it was quite helpful. :)

Not a problem ... I'm involved with outreach, enrichment, and enhancement, so creating a DiGraph or concepts, although impossible, would be an excellent goal. I know groups that are making progress towards it for the UK school curriculum, but it's hard, and I'm not entirely sure that what they're doing will turn out to be useful in the way(s) I'd hope.

I never know what tags to use ... the feature of tagging posts seems useful, but it really needs a better interface.

I'm not sure either, to be honest. It started as an open question.

I'd be happy to implement stuff for you, though. Even if it's your own personal bookmarking service, that's still a quantum of utility. If you have any suggestions, please feel free!

> ... Not sure that I'm keen on the "fighting" articles ...

I've flagged them, I think they don't belong here.

reply


Do you find any of that here?

Not really, I find enough compatible with those themes in things like cheapskate guide.

I took your question of what I would like to see to mean what nitches could laarc become known for given what the larger sites cover. If it sails along as is, I also don't see much point.

reply


The question was intended as "what should I be looking to post", since very, very few of my posts seem to get any responses. But with your list of things you're interested in, it seemed clear that very little of it turns up here.

There's very little traffic, and I'm wondering what the few people here are interested in. The lack of traffic is ... troubling. I'm not finding much of interest, and I'm thinking about giving up, but unwilling to do so without giving it a "proper go".

My perspective is that the volume is low enough that one reposter or even one blogger greatly influences the average direction of the site.

In that sense, I think someone going in a niche direction with posts could give a niche that interests them (and is not the main perspective of some larger site) a try on this site and have a slight headstart on bringing that niche to the larger sites..

The opposite direction for this site, would be if everything on HN were reposted here or with equal chance.. Then the site/community has no specific direction of its own, and why make comments here that could be made in the larger community with the same general focus?

Hi! Nice to "meet" you ... thanks for the reply ...

What was it that you were doing on Xanadu? And what sorts of things do you say about hypertext? I'd be interested in a pointer to your writings on those.

reply


I was originally brought on in 2011 to bring the XanaduSpace 'prototype' written by Rob Smith up to releasable quality (after Ted came across coverage of my ZigZag-inspired operating system iX on hackaday).

XanaduSpace (or, at least the version we pieced together from chunks of various different versions -- the author didn't use revision control) was more of a demo & a POC than a prototype, and so salvaging it was more work than we expected (especially because we needed it to be cross-platform and needed to integrate a nice, responsive editor). We (myself and my buddy) ended up rewriting it entirely, and that became a different (never-released) project called XanaSpace.

Part of the XanaSpace rewrite was switching from OpenGL 1.1 to modern OpenGL -- necessary to make editing responsive, and necessary to fulfill certain demands about the amount of text we can display. But fulfilling the text quantity demands (we needed to support arbitrary unicode in arbitrary truetype fonts & be able to display the whole king james bible on screen at once) were tough, and my partner and I burnt out on it. We were working as volunteers anyhow, so we sort of skated along for a few years.

I worked a little bit on the web-based OpenXanadu, released in 2014 (wrote the code to display the little 'X' logo during loading, and also wrote a substantial amount of code to support a caching proxy that we never ended up releasing & an entire editor we also didn't end up releasing), though the current web-based version on the xanadu site (called XuCambridge, formerly XanaBurger) I didn't have any connection to. I'm still occasionally consulted on ZigZag.

Ultimately, the biggest impact of my tenure on Xanadu (aside from being able to brag about attending Ted Nelson's wedding) has been my work with documentation. Both official and internal Xanadu documentation has been a bit hard to make sense of for newcomers: Ted has a carnival-barker sensibility when it comes to style, a love of puns and neologisms that would put Pynchon to shame, extremely severe ADHD, and hasn't written a line of code since the 60s (though he has a deep intuitive understanding of data structures and their performance), so 'documentation' is mostly Ted making up new words and pontificating about how cool his ideas are -- a real shame because his ideas really are good, if you can figure out what they are. So, with his blessing (if not his oversight), I wrote an introduction to Xanadu internals aimed at software engineers not acquainted with the project: https://medium.com/@enkiv2/an-engineers-guide-to-the-docuverse-d080cdbb73a6?source=friends_link&...

I've also written some simple illustrations of core ideas from Xanadu, in the form of example code: https://github.com/enkiv2/misc/tree/master/ds-lib

I've written some other stuff about Xanadu internals & side-projects related to Xanadu: https://medium.com/@enkiv2/object-eversion-zigzag-and-the-rdbms-2fe9290810ce?source=friends_link&... https://medium.com/@enkiv2/kaukatcr-an-experiment-in-language-design-for-multi-dimensional-spaces-cc... https://medium.com/@enkiv2/proposal-for-a-high-performance-storage-system-for-osmic-branching-histor...

I've also written a little bit about the media theory side: https://medium.com/@enkiv2/xanadu-and-the-rhizomaticity-of-texts-271e33585875?source=friends_link... https://medium.com/@enkiv2/orality-literacy-hyper-literacy-7cf4c779d943?source=friends_link&sk=5...

I specialize in polemics, though: https://medium.com/@enkiv2/guidelines-for-future-hypertext-systems-647b6a10f7dd?source=friends_link&...

Hi! Thanks for responding ...

Do you do anything with your useful links? Do you have a knowledge-base of some sort?

And yes, I kinda hope the site won't go away, but it doesn't see much traffic ...

reply


Yeah, I publish them on some small forum (and pCloud if site goes down).

Started with Windows freeware/updates, then Linux, videos, tutorials, then tech news and so on.

I am scavenging some big tech sites, small blogs, on top of that I am adding some finds outsite the net (magazines, tv shows, ...)

Basicaly, everything that is freely available.

11 years in the making, 200.000+ links (a lot of double entries and updates, so number of unique links is smaller than that).

It looks like everybody moved to HN and Lobsters ...

Hi! Thanks for the reply, and nice to "meet" you.

Hi,

I'm a PhD in Pure Math (Graph Theory), non-exec director of a company that does the maritime equivalent of air traffic control, and now a full-time torturer of adults and confuser of children. I do enrichment and enhancement for math and science, giving 150 to 200 talks and workshops a year.

Although probably not this year. 8-(

nice to meet you! I have enjoyed the content you submit.

I studied math properly a long time ago, and I'm recently starting to study at home by myself again. I also did a bunch of hacking and game making in the past, I'm interested in a lot of things. I got a lot of opinions about software and tried to build various lean minimal pieces of kit but I nothing seemed to gain much interest - it's difficult to find community despite the internet existing. Recently I've been playing a lot of difficult puzzle games like Molek-Syntez, Recursed, Stephen Sausage Roll and Hiding Space.

reply


And nice to meet you! Thanks for the compliment.

What sort of "various lean minimal pieces of kit" do you work on?

reply


Nothing much anymore but I created a simple scheme interpreter, shell, makefile replacement https://github.com/rain-1/single_cream/ https://github.com/rain-1/s https://github.com/rain-1/makes and a gopher client https://github.com/rain-1/gopher

I have trouble following any Twitter (or other!) conversation that becomes at all popular. So I wrote a tool to produce charts of same to help me visualise the content.

First cut, much wrong with it, but I thought I'd share the product, and this particular discussion.

Please note ... I'm not a front-end person, the HTML/SVG code is crap, the code to produce it is crap, and the system is spit-n-baling-wire, user-hostile, and has just so many things that could be included.

But it works for me, and if it inspires someone else, have at it!

That's neat. How did you actually make it?

reply


Got the content by scraping web-Twitter and parsing the content and links, then created a DOT file and let GraphViz do the heavy lifting.
