A saas boilerplate with the fastest build out I can possibly muster and least code. Stack is hasura, graphql, stripe for the API, quasar framework for initial frontend to get easy mobile, native, electron, pwa, ssr, etc.

API has teams, users, roles, permissions, subscriptions and plans, following the paradigm that a user can belong to or own multiple teams and easily switch without logging out, users can be invited or request access to teams, admins can set and change features per plan... Etc...

The idea being minimal changes needed to go to market with an idea. Add a few services or features the 'what's it do' and everything else is ready to go.

I am planning to build a business card scanner like https://dev.camcard.com. Not that nothing like it exists. I am currently working on finishing deep learning courses from fast.ai and wanted to build a cool open source project to apply my learnings. Also wanted to release iOS app which does this on the device without server intervention using MLKit for iOS (I have worked with React native but not on swift - so personally challenging on many fronts).

Connecting a heart rate monitor to a linux system and attempting to study the impact of different activities on my heart rate.

Context: I train for endurance events, and that's seen my resting heart rate fall by about 13 beats per minute. On some days this goes lower during training, and some days it doesn't. The idea is that certain kinds of foods, and certain activities might help me make my training more effective. Also, a part of the inspiration comes from here - https://a16z.com/2019/06/13/ai-doctor-deep-medicine-topol/

Since I couldn't find a good tool to make 3D experiences for the web, I created one that so far it made my clients very happy.

It's node-based, which allows you to try different ideas very quickly within the same scene. You can process models and geometries, or even create your own glsl shader with just nodes. And if you're not a coder, it can also be a good way to learn.

Still a long way to go, but trying to make it easier (and cheaper!) to research public companies / stocks - with both quantitative and qualitative data. https://docoh.com/

Wow! Very interesting. Would love to know how you're building it! Any write up on this would be very helpful. Thanks!

I've recently put this up: https://iamwfh.com/

A lot of the people in our office work from home on any given day. A joke emerged where we come up with funny alternative words for 'WFH', like 'Worshipping Foreign Horizons'. Anyway I quickly ran out of original combinations, so I made something to generate some. I figure there are probably others out there who would get a kick out of it.

Earlier quoted context omitted.

Regarding your twitter question: you can create an anonymous temporary file with no name or backing store since recently (4.x, iirc). You should be able to use dup(2) and unix sockets to send the descriptor over.

Thanks! What i cant work out is if/how dup can be made to be owned by a different process. it needs to be only accessible by that process and should be removed once that process dies. I would like to separate the transfer, of the handle, and the translation of the handle.

Yeah, you can use sendmsg(2) with special flags to send a file descriptor over a unix socket or iirc also a pipe.

It's very useful with kernel-tls or multi-process web servers, to handle no key at all in the worker thread itself or shard processes by something only known after connection establishment, like the HTTP Host header or tls SNI.

I'm writing a book that teaches people coding using JavaScript, the book that takes you from 0 (no coding background) to getting a job as a JS engineer. 2 years I ago, I had a hypothesis to see if anybody could learn coding if they tried.

To test that, I reached out to random people with no coding background, most of them from underprivileged backgrounds. I figured they have fewer opportunities and are more likely to stay through the entire program. 17 of them stayed. You're missing some numbers at the start there, chief. How many people did you reach out to? How m…

His premise is that "anybody could learn coding if they tried", whereby "tried" I assumed applies to only the people who passed those two rounds of self-selection you describe.
