ohadpr··on Show HN: Why write code if the LLM can just do the thing? (web app experiment)
You’d be surprised to know this works even without the tools, with just the context window as a persistence layer.

I did a POC for this in July - https://www.ohad.com/2025/07/10/voidware/

ohadpr··on Voidware: Software that only exists when you use it
In the context of LLMs memory can often mean a broadly defined, application-specific ability to detect, retain and re-use bits of useful context along the journey. In contrast to Persistence which is more like a DB with a schema and clear expectations, reliability, etc.
ohadpr··on Voidware: Software that only exists when you use it
Totally agree. Persistence is a huge part of what we usually mean by state. Nothing stops this from plugging into a real database when needed. But also, nothing stops us from rethinking what a database even is, especially in a world where LLMs have growing context windows and can carry more state internally. Maybe persistence doesn’t always have to mean "write to disk."
ohadpr··on Voidware: Software that only exists when you use it
good question. I think it'll be self-reinforcing, since the context keeps growing with everything the software has done for you, along with every interaction you’ve ever had with it.
ohadpr··on Voidware: Software that only exists when you use it
honestly, kind of both. it started as a curiosity. I just wanted to see if it could even work. but after playing with it, I think there’s something deeper.

the most interesting part to me is the idea of apps that self-customize without being told to. they adapt based on how you use them and what you enter, not from settings or configuration. stuff that changes itself in real time, just by being used. we wouldn't build that kind of software today because it's too weird or specific. but with this, it just happens.

still super early and pretty rough, but it feels like a door opened a crack.

Love this product and the overall strategy.

Wes Anderson’s “The Phoenician Scheme” is coming out in the next few weeks…
ohadpr··on FDA Authorizes First Over-the-Counter Hearing Aid Software
Speaking of the AirPods becoming actual hearing aides - how will we reconcile the fact that it is not socially acceptable to wear AirPods when speaking with someone?

Even if you get to explain ‘oh my AirPods are functioning as a hearing aide’ you likely won’t be able to explain that to other people noticing the conversation and thinking to themselves ‘oh that’s douchey, not taking our your AirPods when talking to someone’.

I just really wonder if this will be able to make wearing AirPods while talking to other people socially acceptable because the current presumption is likely that they are not behaving nicely.

ohadpr··on 85-Byte Snake Game
In 1998 Assembly programmers who typically participated in Demo competitions did a series of size coding challenges. The first one was a Snake game (Nibbles), all in a DOS environment. The winning entry was 48 bytes long.

There were also some creative attempts that took less than 48 bytes and got disqualified. One of those encode the entire game in a series of empty folders using the folder names.

Edit: the original Hugo size coding competitions were created by Claus-Dieter Volko (Alias: Adok).

The announcement focuses on Gatsby’s Valhalla Content Hub rather than on Gatsby the framework.

ohadpr··on Ask HN: What is the cheapest, easiest way to host a cronjob in 2022?
I recently utilized Netlify for this. My build was actually my scraper and I used their Scheduled Functions (cron) to trigger this build every so often.

ohadpr··on Ask HN: What is the most impactful thing you've built?
First implementation of CAPTCHA circa 1997
ohadpr··on Show HN: I made a web-based notepad with a built in unit calculator
Fantastic, thank you for implementing one of my future side projects. I was planning to build a web-based version of Soulver with sharing/collaboration. I hope this can fill that spot for me.
ohadpr··on My service to check whether an item is counterfeit or not
One thing I couldn’t figure out by skimming through the article is who performs the actual authentication (checking if an item is counterfeit)? Is it the two founders? Do they have a team working on this?
ohadpr··on Netlify Status – CDN Issues
I could be. Are you saying this based on data or intuition?
ohadpr··on Netlify Status – CDN Issues
Phrasing can always be better but the point is that there's a way to map your DNS to Netlify which is risky and Netlify hasn't made the aggressive decision of blocking it. They outline in their docs all the reasons why you shouldn't do it, provide instructions for how to avoid it and also offer (but do not require) a hosted DNS setup which avoids this pitfall by design.

Some folks still choose to use this way, some have no other choice for various reasons and some don't care/comprehend the potential pitfalls. I do believe most users avoid using a root domain name for their website.

ohadpr··on Show HN: New platform reveals the Jamstack to non-developers
Thanks, founder of Stackbit here. We currently support NextJS, Gatsby, Hugo and Jekyll with many more coming soon (e.g. Eleventy). One of our goals is being tech agnostic as we want to empower developers to pick the best tool for the job.
ohadpr··on Shippos USPS Time in Transit Data
I think this marketing site would perform better if it had a pretty version of the most interesting graph above the fold.
ohadpr··on Show HN: MeetingBar – A menu bar macOS app for calendar meetings
Great - One thing Meeter does which is great (they are a commercial app that does something similar) is popup a notification with a 'join' button 2 minutes or so before the meeting starts. That reduces the interaction to one click rather than two.

ohadpr··on Ask HN: What weird or hard problems are you trying to solve?
I’ve thought about this concept a bunch and I think there are real commercial opportunities there.

Namely I don’t want to pay Dropbox a markup over S3 and develop a dependency on them. What I prefer is to purchase the software from Dropbox and self host/store it wherever I want. Same goes for email, office suite, photos, etc.

ohadpr··on Ask HN: What are some interesting projects to reuse your old devices?
Another way to achieve this is to avoid the native apps for Twitter/FB/etc and just use the mobile websites. No access to camera/photos/contacts/location/etc.
ohadpr··on SoftICE
Oh my I remember friends debugging Windows device drivers with SoftICE, that was hardcore.
ohadpr··on Bill Lorensen, co-creator of Marching Cubes, has died
"Marching Cubes remains the most widely cited visualization algorithm ever".

It's an awesome algorithm that takes an isosurface (imagine a 3D map of weights) and generates a polygonal mesh. This algo was heavily used in the demoscene and often referred to as 'meta balls'.

ohadpr··on Where Have You Gone, Peter Norton? (2014)
I too had the fortunate experience of picking up his Assembly book around the same age and it was indeed a magical experience. I got into real time computer graphics programming (the demoscene) thereafter thanks mostly to the Assembly.
ohadpr··on Ask HN: Best Static Site Builder?
Hey, Stackbit founder here. Creating websites with Stackbit is and will continue being free. It has a low cost of operation for us and we find its an attractive way for people to experiment with static sites / the JAMstack.

ohadpr··on Paged Out – a new experimental magazine about programming
That's definitely a possibility. I could also hit print and start thinking about whether I have enough of the right color ink in my printer.

My motive is that this content is interesting but not enough to get me to setup meetings with local print shops. More often than not people start businesses to save others time/money and offer convenience, I'm hoping someone did it for this particular need.

People could also print the top pages off The Economist every week and I'm sure some do but the overwhelming majority of those who read it on paper have it printed at high quality and mailed to them.

ohadpr··on Paged Out – a new experimental magazine about programming
Love the idea, reminds me of 2600 and I can't way to read it.

Somewhat tangential: I often want to read PDF files and am never happy with my printing setup. Is there a service that will print any PDF at high quality, bind it for larger prints, and snail mail it to me?
