I've got two main projects I'm working concurrently on in my free time:

- Repairing an Apple II+. So far I've converted it to run on 230V and picked up the A2DVI to connect to modern displays. Next working on cleaning up the floppy drives and repairing the one that doesn't work.

- Reverse engineering the Tandy Z-PDA. I want to be able to synchronize with modern desktop Linux applications, and also eventually write my own PEN/GEOS applications for the PDA.

I'm still working on Habitat. It's a free and open source, self-hosted social platform for local communities. The plan is for it to be federated, but that's a while off yet. I finally cracked ansible/docker-compose provisioning on Ubuntu and plan to expand that out to support Debian also. The groundwork is there. I can finally see an official release in the distant horizon, I just need to put those quality of life fe…

Would you recommend your tool to use with a single instance for a local community that won't be interested in federating? I mean self hosting by one person, likely via docker, exposing to a few hundred people, not federating at all, all data should be kept within the community, not public. If yes, do you think it's already mature enough to give it a spin?

> all data should be kept within the community, not public.

I would recommend it for everything you said except for this part. Everything posted is publicly visible by design. I'm afraid I have no intention of changing that. You're free to fork it if you want though.

I've been building mentions.us[1] - it sends you alerts when your keywords are mentioned on Hacker News, Reddit, Bluesky, LinkedIn and a few other places. For anyone who uses F5Bot, it's similar but with some extra data sources and a Slack integration. It's been a fun project. Dealing with the scale of Reddit (~300 posts/second) creates some interesting technical challenges. It's also let me polish up my frontend dev…

How do you get realtime data from LinkedIn?

For now we use the LinkedIn voyager API's search endpoint

Very much WIP: I'm working on an alternative to subscriptions for online publications. Instead of subscribing to entire publications / blogs, publishers would register their publication on this network and configure thresholds and pricing. Add a bit of code to the site and a paywall will show up, allowing readers to pay for individual articles. The prices would be minimal, amounting to less than a dollar in most case…

I think it's a great idea. Feel free to email me if you're interested in feedback.

This is really interesting, thanks for sharing! I'm keen to know how it compares to a tool like Pulsar? I've been quoted a huge amount to use their service, and it looks like mention.us basically fulfills the same social listening function? If it does then I will definitely push my org to sign up!

Thanks! I haven't used Pulsar, but the general answer is that mentions.us is focussed on sending you alerts for notifications, whereas more sophisticated social listening tools provide a lot more analytics (e.g., sentiment analysis).

If your company just wants alerts when their keywords are mentioned on social media then mentions.us should work great for them. If you work for Coca Cola then you likely need something very different from your social listening tool!

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…

>choose your own accounting software, do not be tempted to hire an external bookkeeper that keeps the books in 'their' systems (accountant lock-in).

~30 years ago I worked at a very small business (3 employees) and they used and liked Quickbooks. The accountant convinced them to switch to some "better" system and for around 3 months they had no idea how much money they had, they just lost all visibility into the system because it didn't work in the way they expected. "If things didn't look right, we'd just go through every screen in the system and press Post." At the end of those 3 months they realized they had unexpectedly gotten into $70K in debt -- this was ~35 years ago when a house was around that much. They had to take a second mortgage on their house. Eventually, they figured out the accounting system, righted the ship, and paid back the second mortgage over a few years. Y2K really helped, with that giant bump in sales.

Working part-time on Lungy, the breathing app I developed whilst working as a doctor during COVID - https://www.lungy.app/ Also, very interested in synthetic biology atm, I’m taking HTGAA - https://www.media.mit.edu/courses/htgaa/

How did you get access to HTGAA? I’ve really wanted to take this course but all of the videos and resources seem locked

Are you able to access last year's: https://howtogrowalmostanything.notion.site/

Otherwise, look out in Jan / Feb next year for applications to be a 'committed listener'.
