What's the coolest website you know?


The definition of cool is, of course, at your discretion.


  👤 kertoip_1 Accepted Answer ✓
Obviously wikipedia.org. Nothing better has been invented in 20-some years. I honestly feel relief when I research some topic and it has Wikipedia page on it, so I don't need to dig through some sh**y blogposts

Edit: I mean: it's one of the very few websites that actually provides sources of information. It's insane it's that rare these days. And most important facts are just placed in visible and easy to spot place, no need to dig through author's life story, thanks for subscribers etc. before getting to the point.

The coolest website I'm using is a very practical one.

https://geizhals.de is a German search website that allows you to very narrowly specify all kinds of things.

Searching for a mainboard with minimum 4x SATA ports and 64GB RAM support in mini ITX format? Easy peasy.

For example, take a look at the laptop category and its filters: https://geizhals.de/?cat=nb

I wish every e-commerce website was built like this.


👤 yeputons
https://www.mcmaster.com/ is fast. I've never been to Georgia, I don't live in the US, I don't even need hardware. But I still enjoy just clicking on random links and seeing a swift response.

Bret Victor's visual / interactive explanations of certain ideas or papers.

Two that I like in particular are his redesign of Strogatz's paper on small world networks and the 'ladder of abstraction'

Lets you listen to the full audio of three Apollo missions. Not only the official mix, but also behind the scenes stuff, like flight dynamics officer, computer supervisor, etc.

Not only is it interesting to hear what engineers on a mission sounded like in that somewhat early NASA environment, but it's also a pleasant background track.


👤 blackshaw
The coolest website I've seen lately is http://howacarworks.com. It's a video course in which an experienced mechanic breaks down a car into all its constituent parts then puts everything back together piece by piece, explaining in detail how everything works and fits together.

I knew nothing about mechanics before starting this series and I'm very impressed by how informative and professionally made the content is. Well worth the price tag (currently discounted as it's still in prerelease, but lots of videos have already been published.)

(Note: I have no affiliation with the creator of this course and have nothing to gain by promoting him; I'm just a happy customer.)

No, I'm not trolling. This is one of the coolest websites I've ever seen, despite it being a personal blog and having no fancy animations. ps: the coolest "site", not the coolest content of the site. While it is very good too in this case.

By far and away my favourite site of all time.

It’s a beautiful example of representing complex data in a manner that’s easy to digest, viscerally understand, even.

It’s also the first time I heard of the Misery Index, which was fun to learn about.

One of my engineering professors still has a Web 1.0 site, "best viewed in Netscape Communicator 4.0 or higher at 16 or 24-bit color". It's actively updated, but hasn't fundamentally changed since the late 90s - some pages still have the Netscape Composer generator tags in them. (For further frame of reference: I last had a reason to go to it over ten years ago now, but still bring it up as a talking piece.

The coolest website I know right now is https://solar.lowtechmagazine.com/.

It’s a solar powered, self hosted version of Low Tech Magazine. The articles are always interesting, but there’s also a ton of good information about efficient website design as well [0].

> The definition of cool is, of course, at your discretion.

OK I'll bite... There's a very cool five letters dot com which exists since forever (I just checked on the Internet Wayback Machine and it has a copy of the site in 1998!). I'll say what it is but I'd rather not link it directly as I wouldn't want HN to kill it (and its owner deciding to pull the plug, you never know you know).

It's basically called "lost.com" (but in another language) and there are just two lines of text saying:

   Lost on the Internet?  Don't worry, we're going to help you
   * <--- You are here

I don't know who created it but that's my definition of cool!

I submitted a site as a joke and now I feel bad because there are a lots of interesting sites submitted.

So let me contribute with 2 other sites, maybe not the "coolest" but I think they will be of interest to some fraction of the people here (for those who dont know them)

- http://www.astronautix.com/ A labor of love of just 1 person, almost of 80000 pages! on humanity space programs,you can spend hours and hours reading about obscure soviet prototypes, NASA suits, the Chinese space probes, etc

- https://www.centauri-dreams.org/ A very active (and long) blog about interstellar travel. Despite the fact the subject is now more fiction than science the articles discussed and reviewed are about actual science done by actual scientists (many good guest posts too)


👤 mkovach

One of the most complete sources of baseball stats including game logs. Yes much of the data is from other sources (MLB, Retrosheet.org, etc) but they really ties things together nicely and I can spend hours on the site.

This was more of a demo page, the original website is long down unfortunately.. Back in the day I'd get excited every time I'd load it! This site is all about esthetic and nothing about the content. I'd say many people decided to become web designers just because of this particular work.

It was hurting my slow DSL back then..

I don't remember the name, but there was a VERY cool futuristically-looking (like Unreal II UI) flash-based site that contained HQ wallpapers (before HD displays became a thing). I still regret not saving it! :_( Yeah, I love flash and think it was a golden era and possible better future killed by Adobe. So, how about https://www.99rooms.com/ ? Great art.

I also liked joke sites like getyourasstomars.com or typicalmacintoshuser.com :D
