“I wonder which field is responsible for disabling the Personal Hotspot feature? About a year ago mine suddenly got disabled in the phone's UI. Since then, the only time it got enabled was when I was traveling and using a travel eSIM. It's sad that phone companies allow carriers such anti-user things.” — jakobdabo

“I made this, fun to see my project on the front page! The main question I tend to get from hacker-types is "what are the tech specs?". The demos run on a Mac with custom software I built for projection mapping/rendering/etc. (the hand tracking uses Apple's built-in framework, which is very good), a small consumer 4k laser projector, and a basic webcam for vision. But really, this is primarily a research/design prototype - I think it's much more important to figure out what the user experience should ideally feel like, if the interactions are even plausible & desirable in the first place; and then work backwards to the technology.” — heliographe

Whistle: Speech to Text in 16.9 MB

“I don't think the challenge with speech to text was size of the binary. In my experience the challenge is understanding my 84 year old Croatian father with a sagging mouth after a stroke, when he's trying to write his autobiography. I just setup Windows speech to text for him last week and it's great to see how he can write an entire page in 10 minutes, it would take him days using the keyboard. But every single sound he makes with his mouth ends up on the page too.” — INTPenis
Triple-A Minesweeper

“I have not seen any comment about the idea that you are being handholded through whole game without even needing to think about what to do next. For me this is the biggest complaint about some games where instead of making a player think what to do and how to navigate game, player basically gets "click her" "go that way" "click that" "congrats you won" so i think this is the parody aspect of this minesweeper. Cant imagine current AAA games allowing player to be stuck for days trying to solve the problem like good old times of monkey island or leisure suit larry” — vincnetas

“Gotta admit, pretty cool! I'm just like.. My interest in smart home stuff is near zero; am I alone? I think it's just an extension of my not caring to "tinker" with my professional workspace. I have all stock OS backgrounds, always preferred a GUI editor/IDE. Barely any customizations that aren't tied to significant velocity improvements.. IDK. I'm not a "space" tinkerer; physical or digital.” — Rapzid
Show HN: Bigwords.page – Turn any screen into a sign. The URL is the app

“I had the idea for BIGWORDS.PAGE when I wanted to display a message on a tablet that I had remote management control over, but no physical access. Configuring it to be a kiosk browser is easy, but how do I get the browser to show my message? So I made the URL be the message. It uses a URL fragment to configure the message. Browsers don't send URL fragments to the server, so I never see your message. There's no backend, and no storage. All parameters are documented, so generating a message link is easy. There's also a built-in editor to make it extra easy. https://bigwords.page/#Hello,%20HN!&bg=ff6600&fg=000000&font... There are a few extra features like slides, animations, and countdowns and timers. QR codes too. Not too fancy, but hopefully enough to be useful. I know the uses for this are pretty niche. But it may be one of those things that you keep as a nugget in your brain, a tool in your back pocket. Not something you use often, but when you do it makes things just a little bit easier. It's open source (MIT), and self-hostable if that's your thing. Let me know what you think.” — SpeakingOfBrad

“As an MLE who has been failing to get anyone interested in classifiers for many years, the hype around Jev makes me scream internally. Yes, I get that a zero-shot classifier is more convenient than the traditional kind, it's very cool. Kind of. But then again plain LLMs have been perfectly cheap and serviceable as zero-shot classifiers for quite some time now, so again I'm back to my internal screaming.” — howunfortunate
We turned EmbeddingGemma 2 into a speech-to-text model

“Hi all. I am Shahir. This was my experiment. First of all - Thanks to whoever posted this on HN. It came as a surprise. Just to clarify - This started as just an experiment to see if we can use the fact that text and audio share a vector space in Embedding Gemma 2 to convert audio to text. Had to hack around a few things, but, it worked. Speed was just a side benefit. Was not aiming for it. The accuracy is good, but not in the range of cloud models, but decent enough for everyday use, and this is just a couple of days work. The WER can improve a lot with more training on varied data. Will try that next. I will opensource the whole thing soon. Might need a few days though. Also, releasing the TTS version for this soon. Happy to answer any questions you have.” — Shershah1024

“Side comment: North Korea seems to be allowing tourists to take videos fairly freely now, and some of those videos are appearing on YouTube. While the tourists' movements still seem restricted, the videos offer glimpses into life in North Korea I haven't seen before. For example: https://youtu.be/HQEYB4QWCjM https://youtu.be/d7m8hZ67Bz0 https://youtu.be/guZQNMEz9as” — tkgally
OpenFatigue™ – Open is the new closed

“I understand the sticklers who are annoyed at people using open weight and open source interchangeably, but it misses some nuance. A common refrain I see is "it's like saying a shareware app is open source!" - that's just wrong. Open source means you can modify, rebuild, and re-distribute the code and the resulting app. Open weights you can do two of those things - you can modify and re-distributed. They can't be re-built, since you're missing the original training data - but they are a form of open that exists somewhere between open source and closed source. Derivative works are allowed, but the source material isn't available. I don't see people complaining about creative commons licensed images or audio being "not real open source", and open weight models seem about the same as that to me.” — kennywinker
