News for hackers. Stuff that matters.

One of two weekend projects; this one's a remake of Lunatic Fringe, the old After Dark module from the '90s. Updated with cel-shaded graphics, break-apart Newtonian physics, and of course a pesky, roughly Einsteinian(ish) black hole.* There's also a daily challenge: a new procedurally generated sector every day, the same one for everyone, with one scored run and its own leaderboard.

* It does spaghettify you, and seen from outside, you slow down as you approach the event horizon. :)

Nobody’s going to like to hear this but … Nextdoor. Especially if it’s a B2C app, ND is your best source for early testers and users. Source: got my first paid users for my first ever iOS app this way thanks to 200 waitlisted neighbors. It works.

Show HN: A/B test images with your eyes using ARKit face tracking

https://saccadeapp.com/

Saccade uses ARKit face tracking to measure which image you actually look at longer in a side-by-side (well, top-and-bottom as it runs in portrait mode) comparison.Import a set of images, and it runs every possible pair, tracking your gaze for a dynamically-timed duration each (typically just a fraction of a second). It then ranks the images in descending order of how long your gaze lingered on...

Re:Strawberry resident launches flood app based on the tides on Wednesday January 28, 2026 @10:50AM (#46796909)
My little nights/weekend project: 13 days from hyperlocal social validation on Nextdoor to live on App Store, this is my first-ever iOS app. And I absurdly, embarrassingly underestimated how complex/non-trivial this problem is.

Hey HN! I'm a founder first, lawyer second. I understand code stacks well enough to explain them, but I've never been able to actually build software, and this has been a chip on my shoulder my entire life.So Scribefully started as my first vibe coding project last summer. I'd read that building something with HN-style upvoting was a good learning project, and I was curious to try Claude...

Re:Bring Bathroom Doors Back to Hotels on Thursday November 27, 2025 @12:09AM (#46065892)
Forget the bathroom doors; can we at least bring back proper shower stall design that uses full-length doors instead of the 1/3-length piece of glass? More glaringly, those of you who know the Hilton MUC for instance, it's utterly mind blowing what they've done: the shower stall floor is on the same plane as the rest of the bathroom floor -- i.e., it's not sunken at all -- and it's not sloped or otherwise angled, either, to prevent water from seeping under the door and flood the whole floor. And this isn't like one-off bug in one room: we've stayed their countless times, in different rooms, and every single one suffers this problem.
Re:Jane Goodall has died on Thursday October 02, 2025 @01:56AM (#45446711)
RIP Jane Goodall. Not to make a flippant pun but, thank you indeed for all the good you brought to all of us. By discovering humanity in our chimpanzee cousins, you helped us see the humanity in each other.

Anybody in SF Bay Area see this last night at 9:04pm-9:06pm +/- 1 min?

Flying very fast from ~W > ~E; i.e., from Marin County, appeared to be coming from Mt. Tam headed over Tiburon.Confirmed NOT ISS (was below horizon then); confirmed NOT airplane (checked FlightAware).No haze in the sky (this was from Marin County). Other stars and moon were crystal sharp, yet this was very blurry/hazy glow, so at first, before I could tell how fast it was moving, I thought...

Re:GPT-4o on Monday May 13, 2024 @10:41PM (#40351116)
But I think this animosity is very much expected, no? Even I felt a momentary hint of "jealousy" -- if you can even call it that -- when I realized that we humans are, in a sense, not really so special anymore.

But of course this was the age-old debate with our favorite golden-eyed android; and unsurprisingly, he too received the same sort of animosity:

Bones was deeply skeptical when he first met Data: "I don't see no points on your ears, boy, but you sound like a Vulcan." And we all know how much he loved those green-blooded fools.

Likewise, Dr. Pulanski has since been criticized for her rude and dismissive attitudes towards Data that had flavors of what might even be considered "racism," or so goes the Trekverse discussion on the topic.

And let's of course not forget when he was on trial essentially for "humanity," or whether hew as indeed just the property of Starfleet, and nothing more.

More recent incarnations of Star Trek: Picard illustrated the outright ban on "synthetics" and indeed their effective banishment; non-synthetic life -- from human to Roman -- simply weren't ok with them.

Yes this is all science fiction silliness -- or adoration depending on your point of view -- but I think it very much reflects the myriad directions our real life world is going to scatter (shatter?) in the coming years ahead.

My newsletter is sad :(
Re:Climate change, clean energy, AV/EV news – Future Perfect on Thursday November 17, 2022 @10:17PM (#33649615)
I've loved reading Dan Ni's fantastic daily tech newsletter TLDR over the past year or so; I'm sure many (most?) of you subscribe to it too, and if you don't, you totally should @ tldr.tech.

A few weeks ago I was inspired to create a similar newsletter tightly modeled after Dan's winning formula, but focused on my three deepest passions: climate change, clean energy, and autonomous/electric vehicles (obviously, for those of you who know me).

Today I'd like to share it with you and hope that you will find it at least interesting, and optimally some non-zero value of useful.

Please meet Future Perfect.

Cheers!

“You don't need to like a thing in order to agree with that thing.” Thoughts?

So this may be a fairly common concept to many people, but weirdly, it only occurred to me a decade or so ago, and I've really come to love it; it's helped put me in the correct mental state regarding several pressing issues over the years.And before someone says something like "yeah, that's what following the data is all about" or something similar, I agree: plenty of times working at our...

Re:Show HN: Autonomous Cars with Marc Hoag on Apple Podcasts on Friday December 14, 2018 @07:26PM (#18686166)
My podcast is the only weekly podcast on autonomous cars in the world. Launched in Feb 2018, I've organically grown it to the #1 spot on Google (for searches like "autonomous cars podcasts") with nearly 10K listens per month. I published Episode 74 today -- the Season 2 finale -- and felt it was finally time to share with the HN community. Happy holidays and all the best for 2019!
