Whilst not quite UPI, the UK has a pay-via-text (sms or Whatsapp) system that nearly every person has access to but barely anyone uses. It amazes me how people naturally gravitate to card-based payments, even when Visa and MasterCard are taking a cut.
I write for my day job so I spend a lot of time in "office" software.
I used to deal with a lot of MS Office documents, less so now. Most forms and web docs are PDFs and there's a growing crowd of people happy to send Open formatted docs. I've used Libre/Open Office for about 5 years as my main office suit and had no issues. It does feel less polished, and I do miss the "styles" thing you can do with MS Word but for copy I find it perfectly adequate.
If I need professional typesetting, or really anything more than Libre Office can handle, I use LaTeX. It's actually very quick.
You can also use MS Office online; their web editor is very good. I use it when I need to preserve an MS Word themed document's formatting.
I really like this. The fact that it's re-tunable makes this reusable for people who would otherwise have to buy a replacement and throw this one away.
We recently moved house and had to return our radio, even just to stay on the same station (they broadcast on slightly different local frequencies across the country to overcome local noise).
I'm seriously considering buying one of these but wouldn't be if it wasn't reprogrammable; I'm not into throw-away electronics because of the environmental impact.
Yep. And that's exactly where it should be. It's insane that we have to prove the same things at every interview when certification already proves these things.
If all you want is a plumber with a certain skill set, then hire a union plumber with certification.
Point well made. I've spent some time with TS, Rust, and Kotlin recently and I really enjoy how they all have these kinds of features. Really feels like they see how well it works elsewhere and learn from one another.
Whilst not an actual answer to your question, I thought it might be a good direction for you to look into.
Also, I've seen Redbooth (formerly Teambox) we'll recommended and since it's OSS it can be self hosted pretty easily.
