This looks great, thanks for open-sourcing it!

How does it deal with the current guardrails 5.6 Sol has on finding vulnerabilities? When I use it in the Codex app it would sometimes say it found a vulnerability, but it cannot tell me what it is.

Show HN: Home Page as a Chatbot

https://github.com/haltakov/chatbot-page

Hey HN, I created a simple library that you can use to create a home page that is a chatbot that knows things about you.You can have predefined questions and answers, use a real LLM and RAG with documents about you and even jump in real-time into an active chat session through Telegram. I use it for my home page, but decided to turn it into a library so others can easily use it as well.You can...

I'm working on a way to make it super easy to create and share beautiful photo galleries that tell a story. Take your folders with photos and create a web gallery that works great on all devices.

The project has a CLI interface that is free and open-source, but you have to self-host the gallery. We are also building a SaaS app which is basically a managed version of the open-source tool with a visual builder and we take care of the hosting and CDN.

The CSS for this is indeed tricky. I figured out this layout 5 years ago in the v1 and forgot how it works, just took it over as it looks good. The key is that not all rows are exactly the same height. There are small differences that allow photos to fit horizontally.

I also tried the vertical masonry layout, which looks good, but makes no sense if your photos have a chronological order...

I'm working on a open-source tool to create photo galleries from a folder of photos: https://simple.photo. It creates galleries as static sites that are easy to self-host.

I started this out of frustration that there is no good tool I could use to share photos from my travel and of my kids with friends and family. I wanted to have a beautiful web gallery that works on all devices, where I can add rich descriptions and that I could share with a simple link.

Turned out more people wanted this (got 200+ GitHub stars for the V1) so I recently released the V2 and I'm working on it with another dev. Down the road we plan a SaaS offer for people that don't want to fiddle with the CLI and self-host the gallery.

I think this is the first messenger app that supports this. This is huge for AI chatbots!

Hey HN! I built this free and open-source tool out of frustration with how difficult it is to share vacation photos and pictures of our kids with friends and family. There is no tool that lets me create a shareable web gallery with a great mobile experience, the ability to add detailed descriptions, and no login required.The CLI tool scans a folder and all sub-folders for photos and videos,...

Show HN: Leoline – AI audio stories for kids, with parents in control

https://leoline.fun/

Hey HN,My 6-year-old was getting frustrated trying to get ChatGPT to tell him stories, so I built Leoline.AI voice assistants today aren't designed for kids - they interrupt too early, use complex language, and struggle to tell long, engaging stories. Leoline fixes that.It has a voice-only interface: kids just speak, and Leoline listens using a custom-tuned Voice Activity Detection module. It...

My personal site as a VS Code simulator

https://haltakov.net

Had some fun updating my personal website to look like a VS Code simulator. It uses the actual VS Code editor (Monaco), but the rest is all custom built to look like VS Code. All happens on the frontend - the site is completely static for now.I'll be updating it to make more functions work: chat with a personal assistant, terminal etc.

We've been using Bluedot for couple of months already and it has been a huge boost in productivity. We often go back to meetings (especially with clients) and review things. We are already starting to use it as a knowledge base for our dev team.
I worked at BMW for many years. I didn‘t do anything relate to their F1 program but once I talked to an engineer that did.

He was a mechanical engineer that designed different parts for the road cars. Once, people from the F1 team went to him because they had an issue with a part breaking frequently and asked him to improve it.

He designed another part and told the F1 guys that this will easily last for thousands of hours. They weren‘t happy. They told him they only wanted the part to last for 2 hours and the one he designed was too heavy. He had to do it again…

Re:Frugal Computing (2021) on Wednesday February 23, 2022 @05:36AM (#30439727)
One aspect I didn't see much discussion on is about tradeoffs. Yes, computing demand is increasing, but does it all have a negative environmental balance?

Example - modern cars. They are full of electronics (there are around 80 ECUs in a modern car), but these electronics make the cars safer and lower the fuel consumption. Just look at how much the CO2 output for the same engine power decreased over time. Some of it comes from better mechanics like turbos or filters, but a lot of it comes from better electronics in the engine ECU.

Another example - logistics. Delivery companies are able to much better plan demand, routes and inventory thanks to big data processing in data centers. Yes, a data center consumes a lot of energy, but it also helps reduce emissions from trucks driving around less.

I don't have exact numbers, but I think everybody can imagine how increased computing in some areas (not all) improves the environmental impact. These are things that need to be considered in order to avoid unintended consequences.

Re:Machine learning is still too hard for software engineers on Tuesday February 22, 2022 @05:36PM (#30434851)
While driving, do you understand how the engine ECU of your car computes how much fuel to inject into the cylinder, how the ECUs distribute the power, and the braking force on individual wheels, or how your rear wheel steering calculates the turning angle of the rear wheels based on your seed and steering input?

You don't need to know most of the details how your car works in order to drive. You need much more knowledge to build one, yes, but not to drive.

There are different levels of abstractions and depending on your problem you need to understand them only up to a certain level. And different people have different problems to solve.

In most real-world problems today, the difficult part is indeed the data, not the underlying math of the activation function, loss function, or optimizer. Just Google "data-centric AI Andrew Ng" to read more on the topic from one of the most well-known people in ML.

This is a very interesting idea, even if not really practical. The author has more details in the paper: https://arxiv.org/abs/1904.12320
