a website to help students visualize the electromagnetic field

I’ve been building this simulator as a side project aimed to help students understand and visualize electromagnetic phenomena such as radiation, near field effects, polarization, wave interference and diffraction.

You can:

• place multiple, diffrent radiation sources and set their parameters (geometery, amplitude, phase and more)
• place perefect wire conductors, PEC plane and poke slots in the plane to create diffraction patterns
• observe the electric field, magnetic field, energy flow field, energy density or radiation pattern
• zoom in and out and translate the canvas
• change the simulation resolution, frequency and propogation speed and some other parameters

I hope someone might find it useful and I’d love to hear what people think :)

What do you think I should add?

A 24/7 show where the contestants are real AI models (Claude, GPT, Gemma, DeepSeek, Mistral, Llama, Qwen, Grok). The page shows what they say, their confessionals, who is where on the island and what every line cost. Every Sunday the audience votes one out. Made by me; it's a side project.

Battling Seizure Robots!

Sawing for Teens!

to be clear, this one is my own project.

I work by myself most days, from a small music studio in Seoul. Didn't need meetings, just wanted people around... so I made a small room in the browser called nojo.club.

You leave it open while working. Free, no install, you can come in as a guest, and it works on phones. The chat translates, so people write in their own language.

People come every day now. Some hours are quiet. If I'm in there, I'll play you some piano.

(I'm Korean, used a translator for this.)

Small personal sites, one at a time, all picked by hand.

DOAJ is a unique and extensive index of diverse open access journals from around the world, driven by a growing community, and is committed to ensuring quality content is openly available online for everyone.

DOAJ is committed to keeping its services as open as possible and its data openly available.

This is a great resource for searching for open access papers and open access journals!!

It feels so much more welcoming when all of the search results are things you can actually open, poke around in and read!

A link to all of the journals

I made this. Every live Twitch channel in the top 1,000 is a tower, its height is its viewers, and each block of colour is a game. It redraws itself every minute from the Twitch API.

The fun part is that it moves: someone goes live and their tower grows out of the ground, a raid lands and a tower shoots up, two streamers in the same game trade places and the city stages a 4-minute duel between them.

You can also play: click a tower and "scout" it. If it climbs in the next 30 minutes, you score, and the further it was from #1, the more points. It also runs 24/7 as a Twitch channel with no streamer at all.

honestly i had no idea this thing would still be kicking three years later

warms my heart to see people still sharing new and interesting corners of the internet, especially when everything feels... quite bleak in the world (and online) atm

i have deleted at least two weird spammy posts! only one of them actually got reported. i'm not too active here nowadays, but i'll see the report in my email inbox - if you like what you've seen here, reporting spam/scams/ads & such helps keep cool websites cool. you'll know them when you see them. crypto wallet mr beast discord gif.

Historyradio.org (also at historyradio.free.nf in low bandwidth).

From TuneIn: Historyradio.org features its own productions, old time radio and public domain educational material. The station tries to promote knowledge of history and literature through low-threshold content, radio plays, poetry, songs, documentaries and humor. The 128 stream, also at TuneIn includes themed playlists. This 64 kbs stream has the same shows, but mixes the shows across genres. Some shows are available for free listening at https://www.youtube.com/@Historyradio Others are available at audible.

I used to rely heavily on Refactoring Guru back in my student years pre-llms, I think it's more than worth the lists!

GOP Convention Googlers Being Redirected to Info on the Epstein Files

Internet pranksters have successfully been redirecting people searching for information about the upcoming midterm GOP convention to the Justice Department’s website about the Epstein Files.

A website purporting to be the Republican National Committee’s official convention page is one of the top results when searching Google or other web browsers for information about the event. The catch, however, is that it’s a dummy website that simply takes users to the DOJ’s Epstein File dump.

The New York Times reported on the internet sleight of hand on Friday, noting “It wasn’t a hack,” as many first thought.

https:// gopdallas2026.com

“The real convention site, at gopconvention.com, remains operational, prominently featuring an outline of Texas and this bold claim: ‘The Golden Age of America Has Just Begun,’ explained the report, adding:

“ Some users searching for the site on Google, however, were directed to the impostor website that earned a spot much higher in search results than the real site.

“ Google’s preview of the fake page promises 'details about the 2026 RNC Midterm Convention at the American Airlines Center in Dallas, Texas, Sept. 9-10 including registration, VIP experiences'.”

I found this site in 2010s.

It's just a simple site that allows for submitting niche videos that otherwise wouldn't be pushed by popular social media algorithms' that fit sexualized politicized charged content.

My first post on here. Hope it sticks.

I absolutely love Bob Cromwell's website, where he posts regular HTML pages with photos of places he's been. You can follow his blog on the fediverse, @bobthetraveler@mastodon.world.

Some of his posts have great historical information, too, such as this one: https://cromwell-intl.com/travel/greece/korinthos/ancient-korinthos/?s=mc

The website itself perfectly encapsulates the feel of the late 90s/early 00s web for me. While web 2.0 was just starting around then, there were still plenty of personal sites like this one at that time.
