Very fun!

I submitted this more 'nonfiction-y' entry:

https://gist.githubusercontent.com/gregsadetsky/08b6cdd56902...

It looks like it's only one entry per person, so I'm playing fair and not submitting this second entry, which encodes a compressed version of the image using a 128 word dictionary (ie each word encodes 7 bits).

The explanation + the dictionary + the encoded image result in 1000 words.

Getting a Spectrum cable modem internet connection in NYC in 2026 is so deeply humiliating.

Dealing with the ridiculously limited upload speed, the outages, the locked router. The 40 minutes it takes on the phone to get it disconnected. Their constant attempts at upselling you cell phone plans and other terrible tech you’d never consider.

Truly, Fios is the most bare minimum. And there are much better options if you can pay commercial rates (stealth.net! Pilot!).

Truly embarrassing and sad.

I remember - or maybe am mis-remembering - that years ago, SD cards used to exist with wifi access. I'm not sure whether you could read the card remotely? Or the card presented itself as a card, but actually streamed your data? But I remember that they existed?

But the thing that struck me even more is that - again, I may be wrong - those cards actually ran Linux? They were super tiny computers?

In a sense, I find it incredible because - is there a parallel world where we'd all be using SD cards as micro computers, and would just have small docks with usb/ethernet? These could have competed with Pis, could be deployed as micro servers..?

Anyway, if someone has real actual information, I'd love to learn more!

Actually - this article [0] seems to imply that this whole micro-world is sorta dead? But wifi SD cards are real and exist? Do they run Linux...??

I'd say yes - it seems like an interesting / worthwhile project, even if only for you to explore new areas/learn..?

Just curious, have you looked at https://browser.engineering/ - and generally speaking, what are your thoughts on the few new browsers appearing these days?

To the larger point, do you know if Rovio did support/pay Eric in any other way than that hoodie?

Angry Birds generated $500M [0], supposedly.

I would also not be surprised if the Rovio developers, designers, testers, etc. who worked on this game did not get a share of that $500M pie - I actually assume they didn't.

But still, you know. Dare I say it - what about "fairness"? :-)

Whenever I see Box2D mentioned (the library by the same author as Box3D, obviously), I think back to this story from many years ago

Could you talk about your setup? I'd love to learn more. Are you using Cubase or something else? Are input/output/backups complicated / do you commit to a floppy disk process?

Do you recommend finding a working Atari? Are they still reliable in your experience?

Thanks!

For those curious, this issue includes (on page 20) an article from the creators of the Graphing Calculator, whose origin story [0] often appears on HN.

I am using 100% of all points from atlas obscura -- see [0] - the data is baked in the html and [1] my source which lists all 30k+ points

agreed re: hotels.com - what I see them doing well:

- don't cluster aggressively ie break out the clusters earlier (even if markers end up overlapping) - allow clusters and non-clusters to co-exist on the same zoom level (this is usually the case - except when maps are implemented to have "cluster only" levels and "point only" levels) - show immediately useful information in the point marker (the price!)

It’s not easy for sure and I’m not a designer or ui/ux expert - just been around maps for a while

I agree with you that the point itself could show that it’s special - or - rely on users tapping/clicking it and then show all the info

In a sense, maybe conveying that the point has more than one data point attached to it isn’t critical - as long as you can see everything inside when clicking it!

Feel free to email me, would love to jam/chat about this!

(op here)

I typically deal with dots at the same place as a single dot and, when clicked, open an infowindow/infopanel that will let people see all of the points’ data.

ie you do need to deal with this issue (by default, no mapping library will do it for you) - and most clustering librairies (or at least their default settings) will also not solve this for you.

The ui for what happens when a point (or even a cluster) is clicked but that point contains more than one point’s worth of data is its own separate problem basically

yeah, I glued the jacket together - but no, I didn't get it printed professionally. that's a great thought!

Unrelated, but related - if you want to have 1 record made, reach out to https://recordcut.com/

Their hours are "2:30 PM to 12 Midnight", I sort of believe... 7 days a week?

Rich will actually answer the phone, and guide you. I've done it a few times (it's an incredibly cool gift). A single record is $12. Extremely worth experiencing it.

I actually posted ntsc-rs as it came up in my research - I'm also looking for something like what you're describing..!

I was also looking into https://codeberg.org/fsphil/hacktv which generates a variety of different analog tv signals (meant to be broadcast using HackRF) - but yes, I want the opposite - an analog-receiver-emulator...? And one that would be "ok" with incorrect signals // fail like an analog TV would... :-)
