eastoeast··on Apple Made a Sports App That Does Almost Nothing. It's Incredible
This was on show hn years ago and it’s still my main sports source https://plaintextsports.com/
eastoeast··on Ask HN: How do you prevent children from accessing your products?
It's obvious from the profiles they fill out. Things like "I love pink things" or "I like kpop demons" etc. Just trendy kid stuff
eastoeast··on Ask HN: When has a "dumb" solution beaten a sophisticated one for you?
I’m mostly a hardware engineer.

I needed to test pumping water through a special tube, but didn’t have access to a pump. I spent days searching how to rig a pump to this thing.

Then I remembered I could just hang a bucket of water up high to generate enough head pressure. Free instant solution!

eastoeast··on Show HN: See what readers who loved your favorite book/author also loved to read
Sweet, looking now to get some recommendations! I'm actually surprised more people don't have my two favorites overlapped more often (Mistborn and Name of the Wind)!

Question: when you don't search a book, it shows "Loved by X people", when you do, it shows "Book twins". I'd be really interested in seeing most frequently loved books, from people that like the book/books I'm searching. It would make it obvious I'm missing something!

eastoeast··on Show HN: A 45x45 Connections Puzzle To Commemorate 2025=45*45
This is a lot of fun! Works decently well on mobile too. One suggestion (although, take it with a grain of salt)- I didn’t notice the deselect since header disappears on zoom. Might be better that way, but might be useful sticked top. Nice work!
eastoeast··on Show HN: Turn raw HTML into production-ready images for free
This is a great idea. I can’t believe I didn’t think of this, given I generate and screenshot so many “poster images” in html just like this. Haven’t played around a ton but seems intuitive. Nice work!
eastoeast··on GPT-5.2
For the first time, I’m presenting a problem to LLMs that they cannot seem to answer. This is my first instance of them “endlessly thinking” without producing anything.

The problem is complicated, but very solvable.

I’m programming video cropping into my Android application. It seems videos that have “rotated” metadata cause the crop to be applied incorrectly. As in, a crop applied to the top of a video actually gets applied to the video rotated on its side.

So, either double rotation is being applied somewhere in the pipeline, or rotation metadata is being ignored.

I tried Opus 4.5, Gemini 3, and Codex 5.2. All 3 go through loops of “Maybe Media3 applies the degree(90) after…”, “no, that’s not right. Let me think…”

They’ll do this for about 5 minutes without producing anything. I’ll then stop them, adjusting the prompt to tell them “Just try anything! Your first thought, let’s rapidly iterate!“. Nope. Nothing.

To add, it also only seems to be using about 25% context on Opus 4.5. Weird!

eastoeast··on Launch HN: Phind 3 (YC S22) – Every answer is a mini-app
This is pretty cool. Congrats on the launch! With anything, there will be multiple corner cases to handle, but I'm initially impressed!

Low hanging fruit feedback that would really improve the experience of many: I haven't been able to pinpoint it, but there seems to be double scroll bar enabled in both the container of the whole page (top navbar, and "non-content") and the actual wanted scrollbar inside the rendered content. Because of this, especially on mobile, when I try to scroll, the outside scrollbar "captured" my scroll input and I could never get past the Headline.

Might be a missing height: 100vh; or overflow-y: hidden in your min-h-screen class. Cheers!

eastoeast··on Show HN: I built an interactive HN Simulator
Too accurate. Awesome!
eastoeast··on Ask HN: How did your startup get its first real users?
I’m documenting my exact process of this here: https://opus.cafe/goal/jj/26#progress-6

Still a lot of learning to go, though

eastoeast··on Ask HN: What Are You Working On? (Nov 2025)
It's been a while. But I believe what caused me the most headache while trying to build something like this was handling the interactions between different elements. Declaring which objects were affected by "attacks" or could be "player interactive" or "affected by player but not by NPC". Really this boiled down to proper inheritance. But I found myself so deep and tangled a fresh reset would have been better. Then determining if the object itself or an "objective manager" should perform the calculation each cycle.. etc

It was messy. I ended up having NPC, Item, Attack classes and for each a NPC Manager, Item Manager, and Attack Manager to calculate all their interactions and states.

That's why your project seems interesting because it seems to handle the heavy lifting of behaviors and "behind the scenes".

eastoeast··on Ask HN: What Are You Working On? (Nov 2025)
This is really cool. Nice project!

I tried doing something much more rudimentary before. Will be following

eastoeast··on Ask HN: What Are You Working On? (Nov 2025)
I’m still working on https://opus.cafe/ outside my full time job.

It’s been a fun 3 year project. Just launched on iOS and am in user acquisition phase. Totally new learnings here! Getting users is definitely the hard part... I can build something all day

eastoeast··on Any hardware tinkerers have suggestions for building this mechanism?
Haha, you are correct. I think they'd have to be a little bigger! Now I'm thinking the gearing might slip during movement.
eastoeast··on Any hardware tinkerers have suggestions for building this mechanism?
We are discussing using a string and gear but haven't tested. Thank you!
eastoeast··on Best strategies to grow from 300 –> 1000 users?
You can see what I’ve tried so far in my goal progress. Any other things you guys would recommend? Thanks!
eastoeast··on Show HN: I made a Doom-like game fit inside a QR code
This is super cool. Recently, I tried making an offline, P2P chat program that fits inside of a QR code. In case network was down, the code could be scanned by mobile, allowing users to join a chat room. However this doesn’t seem possible at the moment, as 1. browsers don’t allow offline direct communication for safety reasons 2. couldn’t fit all needed data/prereq modules within the QR.
eastoeast··on Show HN: LinkedIn sucks, so I built a better one
Having both a hardware and software background and applying to both fields, I have the same problem. The UI needs a lot of help (sidebar needs to go), but I've been building this https://thebestresumewebsite.com/ to combat this issue. Basically, you can write a bunch of bullet points, then checkbox which ones you want for different variations, so you don't have to keep deleting bullet points!
eastoeast··on Auntie PDF – an open source app built using Mistral OCR
Awesome UI!
eastoeast··on [dead]
Converted this python CLI I made at work to JS. Colleagues would sit around my laptop during lunch to see who could score the highest.

There are a couple ways to rig the game to be in your favor if you can figure them out. Has to do with screen width and speed/row count calculation

eastoeast··on Show HN: Probabilistic Tic-Tac-Toe
This is just awesome, great idea. The computer doesn’t seem to defend against obvious, probabilistic winning moves (doesn’t block a final square). But funnily this works to its advantage sometimes if you end up rolling frowny
eastoeast··on Ask HN: How to handle user file uploads?
Following a similar stack, has anyone found success handling iPhone HDR and Live Photos? Both seem to give issues to standard HTML formats. I believe we’re using an AWS service to convert videos to various qualities (maybe Elastic Transcoder or Media Convert), and those iPhone video formats causes the service to error out.
eastoeast··on OpenAI makes ChatGPT 'more direct, less verbose'
I feel they've leaned too far in one direction, and will (hopefully) adjust behavior again soon.

E.g. "Create a list of 20 potential names for a startup about Ovens"

Chatgpt returned only a single response to this. When prompted for 10 more options, it only return two new options. Seems it is forcing itself not to count properly to satisfy brevity requirements.

eastoeast··on Show HN: My first software project – a website to set goals and track progress
Great! I'm glad people still look for a site like this.

I had never heard of 43things, but I've always thought my idea for a "goal setting website" is reminiscent of the "old internet". Simpler times. More about doing cool things rather than gaining attention. Their concept looked pretty cool. I've always wanted to implement a lexer but haven't had a chance yet. Maybe will try it soon

eastoeast··on Show HN: Rank Anything – everything in the world, ranked best to worst
I really like this idea! May I suggest that on mobile, maybe each ranking should be rearranged to sit vertically instead of horizontally.

Right now, the ranking number, upvote/downvote, and item name takes up the same row. This causes a lot of wasted space and awkward reading.

If you switched the horizontal row to column layout on mobile, it'd be way easier to read. Excited to see where this ends up!

eastoeast··on Show HN: My first software project – a website to set goals and track progress
Thank you very much!

1. All the users are my personal network. I'm in the process of figuring out "how do I grow past people I know?"

2. Now that I've emerged from the technical abyss, user growth + sustainability is what I'm starting to think about. I have a few ideas, mostly dealing with using this as a tool for teams or schools, but nothing solid yet. Open to any thoughts!

eastoeast··on Show HN: My first software project – a website to set goals and track progress
Thank you! It took many, many iterations to get it looking decent and intuitive on first impressions, so I'm really glad to hear this.

My process pretty much followed "build what I need next". So I started with Angular YouTube tutorials, then set up a basic database in Dynamo, using Lambdas + API Gateway. Then as the complexity of the site's data structure changed, I hard pivoted to PostGres (classic). Then I needed to make auth and accounts, so I set up Cognito. I tried to capture a lot of my learning within the site itself in various Goals.

This all happened before chatGPT was around. Then of course when it was available, I would ask it to help me with basic concepts and "what are industry standard ways of doing this?"

What I found to be true 99.9% of the time is, everything I'm trying to do has already been done and solved, I just need to know how to Google it properly. One of the biggest challenges was setting up image + video compression, but even still when I really sat down to handle it, didn't take more than 48 hours to figure out. PWA push notifications were another tough one. Happy to chat about any technical specifics!

Finally, I'll say this. I tried to reinvent the wheel designing the UI many, many times, not wanting the site/posts to look like Facebook, Twitter, Reddit, etc. Ultimately, I realized there's good reason all these sites follow the same format: it works, and users understand it intuitively. If I had just decided to use what already works from the beginning, I probably could have shaved 6 months off the project.

eastoeast··on My first sw project as a hw engineer- a website to set goals and track progress
Two years ago I started building this project that allows people to document their learnings and progress in real time.

The idea is: if you're learning something new, like playing "Für Elise" on the piano, you can share your experiences, struggles, and eureka moments. Then, someone else wanting to learn the same thing can learn from your journey later. Over time, we get a collection of user experiences about overcoming different challenges.

Each progress you make, the site prompts you to reflect upon things like "if you could go back in time, what do you wish you had known?".

This was my first webdev project and everything was self taught. It's been a great passion and learning experience!

All feedback is welcome, big or small. Hope you enjoy it and find it useful.

Stack: Angular, Python/Postgres, AWS, PWA service workers for notifications.

eastoeast··on Opus Café- A website to set goals and track your progress over time
Hey HN, 2 years ago I started working on this project to provide a way for people to document their learnings and progress over time.

The idea is, if you want to learn to "Play Für Elise on the Piano", and then I want to, I can use the things you've documented- your impedance, eureka moments, lessons you learned, for myself. At the end, there will be multiple users' collections of how they overcame and solved various problems themselves.

Each progress, the site prompts you to reflect upon things like "if you could go back in time, what do you wish you had known?".
