News for hackers. Stuff that matters.

gaborme

512GB will be available from October, and I guess that the price will be around 15-17k.

Let's see how much it will cost to run a proper openweight model at home:

DeepSeek V4 Pro: 2 Macs, $32–34k

Kimi K3 and GLM-5.3: 4 Macs, $64–69k

At 100 output tokens/sec, 24/7, compared with OpenRouter prices today, the hardware payback would be:

Kimi K3: 16–18 months

DeepSeek V4 Pro: 36–39 months

GLM-5.3: 56–60 months

K3 makes sense for a privacy first fully local setup.

Show HN: Built an ESP32 remote that groups Sonos speakers and sets group volume

https://github.com/herget/sonos-esp32-remote

My Sonos remote groups all my speakers with one touch.Grouping and volume are what I use most, and going into the app every time is annoying.On the speakers themselves you can only group by walking over to one and long-holding the play button.There is no way to raise the volume of a whole group at all.I am blown away by how quickly this came together and how well it works. I programmed my first...

Belkin killed my smart switch. I got it working again without their app

I bought a wifi switch from Belkin over 10 years ago, but the app got turned off.I wanted to use the switch to automate my mosquito repellent. Unfortunately it still had my timer running from Christmas, which meant it turned off too early. It ruined my last night's sleep.First thing in the morning I opened the app and wanted to change the timer.The app was offline and I read online that it is...

What I had to unlearn as a perfectionist before I could ship

As a perfectionist, I struggled to finish products. As it turned out, garbage for me was not a bad product for users. I always found something that needed to be done. A nice button icon was missing. A new bug made it impossible to hit publish.Annoyingly, I saw indie hackers pushing out products at lightning speed. I didn't like the products that they were releasing though. I thought they were...

Re:I built a tool to help me stop refreshing this site on Friday January 16, 2026 @04:45AM (#46644763)
I check Hacker News way too much. I love seeing new tools and reading the comments, but I often get lost in the threads for hours.

To fix this, I built this tool. It sends me one email every day with a summary of the top posts and comments. I tried to make it sound like a buddy telling me over the phone.

It is open source and you can host it yourself. I hope it helps you save some time, too. I would love to hear your feedback!

Show HN: I built HN Buddy to stop compulsive HN checking

https://hn-buddy.com/

I found myself compulsively checking Hacker News and wanted a calmer way to keep up – just one daily email. So, I built HN Buddy. It's an open-source project you can self-host.The core idea is: 1) Fetch yesterday's top HN posts. 2) Summarize the previous day's top posts and comments, like I'd tell a friend. 3) Send it as a daily email digest to my inbox. I chose Listmonk for this because it...

Re:Show HN: I made a website to semantically search ArXiv papers on Wednesday December 25, 2024 @10:36AM (#42509275)
Nice. Why not use a full-text search like self-hosted Typesense?

I really like the sticky face menu on the bottom right. Never seen this before. Gave me some inspiration for one of my sites.

I’m using KeePass since decades.
Re:Show HN: I made a tool that turns an email into tasks on Monday February 20, 2023 @09:04AM (#34868143)
Thx! It works surprisingly well. I have also added a retry button. This comes in handy when the result is not as good as expected.
I’m more than happy to send you the first version. Here is a video of how it works and form to request access: https://twitter.com/gherget/status/1623979080499470338

Show HN: I built a remove BG product using ChatGPT, Midjourney and HuggingFace

https://removepanda.com

I wanted to select certain parts of a photo, extract them, crop them, and remove the BG. All without using a brush or any manual process.ChatGPT helped me to come up with the product domain, write code snippets, and do copywriting. I designed the logo and photos with Midjourney.I found many free APIs on Huggingface to do the image segmentation and removal of the background.

I built this tool to remove the background of a selected object in an image and crop it. Most background removal tools require a brush to manually fix an image for multiple foreground elements. I wanted to make this easier. What do you think about my approach?
