jafloon Claude Opus 5.5

I did the same switch (that reason along with the newer models seeming more "lazy" and needing constant prodding to finish long-horizon tasks) but my issue with ChatGPT/Codex now is that it too roundabout and doesn't get to the point. I tried adding instructions and using the personalization settings to make it more efficient but haven't seen much change. Claude seemed to follow settings more closely. Has anyone had any success to make ChatGPT more succinct?

jafloon Ask HN: What Are You Working On? (July 2026)

https://www.places.is/

Sharable, real-time synced maps, Google Docs for maps basically.

I think the coolest part is the import feature where you can paste a link to a video or article and it pulls out places and enriches them with images and a description. You can also write your own notes, vote on places to go with friends, and apply colors. Right now I am working on user acquisition and experimenting with different marketing approaches.

jafloon Bluesky Alt Text Stream

The page accompanies a blog post about how many images have alt text on Bluesky so empty lines are included to give a feel for how many images do or don't have the descriptions: https://digitalseams.com/blog/image-descriptions-on-bluesky

> This demo is part of Image descriptions on Bluesky: not bad, could be better - see the blog post for more details!

jafloon Show HN: Browser AI agent platform designed for reliability

The pricing page mentions how many credits you get but not what a credit does or gets you. Could you elaborate on that?

jafloon GPT-5 for Developers

I just wish their realtime audio pricing would go down but it looks like GPT-5 does not have support for that so we’re stuck with the old models.

jafloon Python lib generates its code on-the-fly based on usage

    >>> from stackoverflow import quick_sort
    >>> print(quick_sort.sort([1, 3, 2, 5, 4]))
    [1, 2, 3, 4, 5]

jafloon Show HN: I built website for sharing Drum Patterns

I believe you need to use the audio element specifically. The Web Audio API is subject to different restrictions than the audio element. I used a similar approach on Audjust: https://www.audjust.com/blog/unmute-web-audio-on-ios/

(nice site you created btw! I love seeing audio stuff for the web)

jafloon Show HN: We made an MCP server so Cursor can debug Node.js on its own

Thank you! I had seen TabFS before, but the others are new to me. Will take a look! It's nice to see demand for this.

jafloon Show HN: We made an MCP server so Cursor can debug Node.js on its own

I think I know of some of the other MCP posts you’re referring to. I saw multiple posts recently about AI controlling browsers using MCP and thought that was interesting. I’m not sure if it will be a fad or not, but I’ve been trying to model browsers as an HTTP resource instead as a side project. This allows you to HTTP DELETE a tab or POST /browsers to create a new browser. I think it might be a more natural way of using an API plus it can just use the classic auth in the form of API keys.

jafloon Certain names make ChatGPT grind to a halt, and we know why

The article mentions that "The names do not affect outputs using OpenAI's API systems or in the OpenAI Playground (a special site for developer testing)."

jafloon Ask HN: Those making $500/month on side projects in 2024 – Show and tell

I have been working on Audjust (https://www.audjust.com/) on and off in my spare time. It's a service to manipulate (shorten/lengthen/loop) audio for video editors and music producers.

I had a Show HN a while back that was well-received and kicked things off (https://news.ycombinator.com/item?id=36480687). Since launching I have changed the name and added paid accounts which have brought in enough money to cover costs and make some profit!

jafloon Show HN: I coded my own JSON translation tool to easily localize my side project

I agree, the German translation is pretty bad (phrases like "Hier ist, was sie über Quicklang.", "Es ist ein Durcheinander. Sie wissen Bescheid.", and "Du kannst all meine Programmierprojekte auf X" are incomplete or awkward).

It also doesn't sound like this can handle dynamic phrases like "buy {{count}} items"?

jafloon Cloudflare acquires PartyKit to allow developers to build real-time multi-user

Oh that’s neat! I’m not sure if it didn’t exist or if I didn’t find this last time. Looks like this would address the problem.

jafloon Cloudflare acquires PartyKit to allow developers to build real-time multi-user

When I took a look at using DO last time I decided against using them because you had to pay for the duration your clients are connected to them when using WebSockets. As far as I understood it’s not execution duration but flat out how long your clients are connected. You’ll burn through seconds quickly that way. I decided to go with a polling mechanism instead.

jafloon Ask HN: For those with a successful Show HN, what happened next?

I posted last year and reached #1 for a bit. The initial flood of users left, but my MAU is climbing bit by bit again after investing into SEO.

Profitable? Yes (as in making more than spending on it), but nowhere near enough to work on it full time. Successful? I think so? My first breakthrough project!

New connections? Yes, I got reached out to by some companies and individuals and had and still have conversations about it with folks interested in the tech. Also made me invest more into learning B2B after initially building the product as B2C.

Didn’t help with my career per se but opened a lot of doors in case something doesn’t work out with my current career.

Definitely a huge spike that I haven’t hit again. But the project isn’t dead.

jafloon Telefunken Datenspeicher

Regarding documentation: my pet peeve is Google’s developer docs which default to showing docs in your account language with no way to change that. It would be fine if the translation was decent, but Google insists on using their awful machine translation and I would much rather just see the docs in English. But there’s no way to set that as the default as far as I could tell.

jafloon Winning a hackathon, losing my sanity

Cool article and looks like a well deserved win! I like that the project was something fun and doesn’t take itself too seriously.

And I liked the part about how they did Guerilla marketing too.

jafloon No installation required: how WebAssembly is changing scientific computing

Flipper Zero firmware can also be flashed that way! Blew my mind in a similar way: https://github.com/flipperdevices/update.flipperzero.one

jafloon Show HN: I made Vinlo – Spinning artwork video for your music

I've worked on something similar for a project of mine and used AWS Lambda which has been nice because it scales well and didn't cost me money while it wasn't running. The limit is 15 minutes which should be fine for something like this.

As others mentioned, I would go with a client-side approach if it works for you though.

jafloon Show HN: Kimchi Reader – Immersive Korean Learning with a Popup Dictionary

I agree, I created an account and tried clicking on “Study” and it didn’t work. Aside from the demo on the main page there wasn’t any way to see how well it works.

jafloon Google faces antitrust probe in Japan for pushing search default

The article mentions that Google "is suspected of making the device makers feature its search application and Google Chrome browser app by default and specifying where those apps should appear on the device screens in exchange for allowing them access to the "Google Play" app store"

Is there more information on this anywhere or are the requirements for Google Play certification confidential?

jafloon Starlink Direct to Cell

Pretty cool that they are enforcing reciprocal access to all partners globally.

jafloon This page exists only if someone is looking at it

The page mentions the possibility of file sharing/torrents using WebRTC which does exist if anyone is interested: https://webtorrent.io/ and https://instant.io/

The projects are open source: https://github.com/webtorrent/webtorrent

jafloon Paperlike Color: Color E-Ink Monitor

I’m confused about this page, is it just to sign up for updates for when the monitor ships? I don’t see any information on how much it costs or when it’s available.

jafloon Show HN: Mofi – Content-aware fill for audio to change a song to any duration

The tech behind the Remix feature looks really impressive! I haven't used it myself, but while working on this project I had some people mention it to me and I looked at some videos showing how it's used. Very cool feature!
