They do. I've been meaning to let users edit the tags, though.

huh, do all text posts go in /l/ask?

Clickable links in the post body! Nice!

I was shocked how good this is. Then I noticed how great the rest of the site is too!




I used to build tools like this at my first job (gamedev circa 2008):

We built everything in C#. It made sense at the time; the browser javascript ecosystem barely functioned, and our desktop app was lightyears ahead of anything else.

Fast forward 15 years, and it's really interesting to see that we weren't even slightly on the right path. Unity and Unreal Engine would've steamrolled us (if the company hadn't folded). And now in 2022 it's so easy to build tools with javascript that I still wince at the years of esoteric C# knowledge I accumulated.

It's fascinating how much effect one decade can have.

Cheers to 2032 -- it's tantalizing to look around today and wonder "Which of these tech stacks will seem in 2032 the way C# seems in 2022?"

I can't wait to see how makers build tools in the 2030's. It's been feeling like the pace of tech has been slowing down, but it's always an illusion.

Cool post

/l/c++ works now.

I haven't updated the API docs yet, but items now export tags. And since it's 5am, I'd rather leave a quick note here on how to get them.

Here's what looks like:

    "by" : "rain1",
    "descendants" : 0,
    "id" : 2545,
    "keys" : [ "nokill", "/l/electronics" ],
    "score" : 2,
    "text" : "",
    "time" : 1610283131,
    "title" : "Why three prongs?  Electrical ground, stray voltage",
    "type" : "story",
    "url" : ""
To get the tags, use this algorithm:

1. Check whether there's a "keys" entry. If not, return an empty list.

2. Remove all keys that don't begin with a forward slash, then return the list.

I'll explain in more detail why I chose this approach. But for now, just know that you get more information this way. (e.g. you can see whether a story is flagged by checking for the "flagged" key.)

A surprising oversight on my part. Let me look into it when I’m not juggling a job and a puppy.

Since it’s the first feature request in a year, I’d feel bad not doing it. So let’s see if it happens.

Thanks Shawn. For context this API is very similar to the Hacker News one: In fact it took minutes to add it to my own site (

@shawn: I just noticed that the API doesn't export the "tags" of a submission. For example the JSON for this submission missises the tags "meta,laarc,api,programming". Do you think it would be a lot of trouble to export them?

Also wrote a post about it!

It looks sort of interesting, but is there a way to try it out without granting it sudo privs to my browser?

Up until this exact moment, I had no idea that a percentage was dimensionless. Ditto for angles.

The concept of "dimensionless quantity" just refused to compute.

But now whenever I measure a circle, there'll be a voice in the back of my head yelling "Uno!" whenever it reaches one radian.

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.

This is hard to read on my computer

You might have more luck if there wasn't a $5 cover charge. I was interested in trying it out, and $5 is indeed cheap, so maybe I will. But it raises the activation energy considerably.

The other concerns are, will the data go away if your service shuts down? Can I add an adwords tracker? What if I need to inject custom HTML, or custom scripts; is it possible? Etc.

A few of those would be answered by a free trial.

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 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:

What caught my attention about your site is that I know from experience how hard it is to create a fork of 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. :)

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

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.

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

I see you got published on Feb 11. Congratulations! How long have you been working on this?

Non-paywalled version:

This submission is one of the most unique I've ever seen, let alone to laarc. I love the idea of an automated mosquito cannon.

The 50% accuracy is impressive too!

Title got me interested!

I've been playing a lot of Pavlov VR. Surprisingly, they have an active custom games scene. Lots of different game modes, from zombies to Among Us style traitor-vs-innocents. was interesting too, though not nearly as interesting as interesting as this. Their conclusion was basically "He probably cheated, but there's no way to know."

Ug the acer ferrari, it was accidentally like a real ferrari:

Acer was probably the worst manufacturer at that time and needed to put a desktop CPU in. They didn't put any hardware/firmware throttle in so they would overheat and trigger the CPU thermal limit if you could not install an OS fast enough.

When our procurement office let us choose them as one of the few options, I assumed it meant someone in procurement was having a midlife crisis.

Why not just put stickers on a run-of-the-mill look laptop to personalize it? Having some different colors within the same model might be a slight improvement in cheerful looking meetings, but procurement generally can't be bothered with extra constraints like making sure the right computer goes to the right person.

This seems like an install/setup guide for an alternate package manager that installs an almost normal webserver?

I don't really get what yunohost is supposed to be providing AFA simplifying the experience, given it is apparently not it's own bootable image of a distribution.

I think most existing distributions have a webserver that comes up and serves a directory in /var and they don't serve any PHP. Unless you know php or want to do click and pray with wordpress, I would consider no PHP/etc and no enabled modules the right config to start a home blog.

As such, I think this is really too advanced for the stated audience and more of a description of a possible later option.

The condenast cookie settings has an interesting anti-pattern. A left/right toggle where some direction must mean off.

I think the little Arm boards are good enough now for surfing, etc.. But for a desktop with lots of RAM and cores an AMD Ryzen would be good.

The only use I really have for a lot of cores is compiling the software I am using on the machine, which seems like circular reasoning for consumption, particularly since browsers and such things with long compile times are things I least want to contribute to.

I find this article a bit disappointing compare to earlier ones from the same blog.

To summarize my dislike, I find the premise that:

1. Trying to get free as in beer CPanel style service while using Tor for your own privacy and wanting family to accept unsigned certificates as a sign of trust in you. The innapropriate trust is in a hosting company with an unclear business model which can include relying on grey areas to sell MITM access to a 3rd party for injection of spyware downloads.

I find this markedly worse than the pre-existing standard:

2. Forcing friends and family to accept your preferred large provider for file sharing or photos that is probably giving you several gb for free and has some reputation to maintain for their freemium upsell.

I would have preferred:

3. Using classic shell access ~/public_html from some small UNIX community or other non commercial site.

4. Using more unusual setups to introduce friends and family to p2p networks, filesystems and similar.
