My pursuit of happiness, I'm in fear of quitting my current job and go for a working holiday to Australia, I'm excited while still trying to overcome the fear of not having a stable and well paying job because I don't find any joy in this job no more , so I am working on mentally getting out of this, I want to truly let go "money is more important than my happiness" idea.

I embarked on a working holiday to the UK in 1998. Quit my job in South Africa and left with nothing but a backpack. Opened up my world, I worked for Coca Cola, the BBC, an investment bank, got wrapped up in the dot com boom, met my American wife, met the smartest people in the world, some invested in me, moved to the States, started a business that now has millions of customers and a team of 40 that my wife and I 10…

I'm at a similar place to GP. Reading this comment and the employment[1] page for Defiant was a great reminder of some of the things I've been struggling with lately (and how alternatives can look). Congrats on taking the leap many years ago and setting up a company with a deliberate work culture that sounds brilliant to be part of!

As a native Spanish speaker, I often used ChatGPT to improve my emails in English. It was very time-consuming having to type the same prompt multiple times in a day to set my writing style and format. That's why I decided to build an app to simplify my process. You can set the style and format just once, and with a single click, you can improve your text. You have the option to include the email thread or any relevan…

Why not create a GPT

I experimented with it and was able to get everything I wanted, but it required many extra steps and prompts. For instance, my app automatically detects the tone of the message while I am typing, whereas in GPT, I need to manually request the tone after making any changes to the text.

I have been working towards building and understanding the shift in search / information retrieval.

To that end, I just did a show HN on a couple of my projects

What if google did not focus on hyper commercialisation? 10 Blue links, but sorted by how they answer your query- https://www.unlob.com

Can we answer questions with lesser hallucinations? A snippet cited answer engine which only picks links that focus on answering your query - https://www.unzoi.com

Working on ARC-AGI (2). Trying a few different approaches including gradient descent mechanisms to construct programs in DSLs. Was really inspired by the recent differentiable logic gate networks work from Google, and believe there is a way to adapt it to generate programs instead of cellular automata rules.

This sounds cool, could you elaborate more?

I've been putting together a no-nonsense free invoice generator, for people (like myself) that only occasionally send invoices. It's more-or-less a WYSIWYG editor, and the state is stored in the URL, so you don't have to worry about keeping track of where you stored your copy - if you've sent someone an email with the link, you've got a copy. This project was born out of the frustration of trying to generate an invoi…

Not be negative about bestfreevoice, or any other invoicing tool, but it always seems like developers and early-stage entrepreneurs don't understand invoicing. First major disconnect is that not every country uses invoices, but may use receipts instead. This is true for the USA for example, so many US devs (for example: Stripe in the early days) are not familiar with the concept of invoicing. Technically there is no…

While all well and true. Some scale is assumed.

There’s plenty of need for basic use invoicing like this. Generate an invoice as a way to bill someone or serve as an estimate for work/project cost. Not everyone is at a place where it needs to be so formal and integrated into a complete solution that tracks the dollars from invoice to balance sheet to income statement, etc. It’s a lot especially for people that are just freelancing and need a similar probably infrequent way to send a bill. They probably are just tracking things in a spreadsheet and not even big enough to use quickbooks or anything else. It would be a poor use of time and over engineering to put that all in place and setup things that cost subscription dollars in perpetuity just to bill for a one off charge. Or even a handful of them.

When I think of people I pay, my lawn guy and my housekeeper both just text me how much I owe them. Then I zelle them. They both have dozens of clients at least and I imagine they are doing this way for them all. If I were a business, in May insist on getting an invoice to load the AP into an accounting flow from my end but they wouldn’t really want to change their system of doing things just to comply with my request. So, they may want something like this that just basically converts the text message info into an official looking invoice.

I feel the real problem is everyone is assuming this side project type thing to solve every edge case that exists in the world. Even the bigger guys like stripe. That’s the wrong take. They offer a solution, you have to evaluate of it fits your needs, if not, use something else. If you’re in a locale that mandates something completely different, use something else. This project is being very transparent about what it does and how it works, which should help you out if you have a requirements list to compare it to.

I made this spectrum analyzer/music visualizer recently. It's meant to be easy to use by just going to the URL and looks great on a 4K screen, jameskdouglas.github.io/frequenSee/

For some clients, electronics for a low impedance guitar pickup (pick up all the signal then process it later instead of building in filtering to the pickup).

And an automated design app that turns a 3D model from Fusion into something that's easy to change the parameters on. That way people can easily just type stuff in and move on to manufacturing. This started for staircases - for companies that make like 20 sets of wood staircases on site every day they want to turn that 1hr of drawing into 60s of data input.

I dove into using LLMs together with MCP servers for the first time this weekend. Absolutely incredible. In addition to the code assistant, I configured a Grafana's MCP server with Cline, so that I can chat with an LLM while having real-time metrics and logs. For context, I self host grafana in addition to a bunch of services on a raspberry pi. Simple prompts such as "why has CPU been increasing this week?" resulted…

This sounds really cool. Do you have any guides or notes on how to set this up? I've been looking for something to dive into for LLM and MCP.

Would be interested in this too!

Finishing up my PhD thesis on low-resource audio classification for ecoacoustics. Our partners deployed 98 recorders in remote Arctic/sub-Arctic regions, collecting a massive (~19.5 years) dataset to monitor wildlife and human noise. Labeled data is the bottleneck, so my work focuses on getting good results with less data. Key parts: - Created EDANSA [1], the first public dataset of its kind from these areas, using a…

I'd love to turn my spectrogram tool into something more of a scientific tool for sound labelling and analysis. Do you use a spectrograph for your project?
