technicalc-core VS ppp_thing

Advanced maths engine is actually open source! https://github.com/jacobp100/technicalc-core

The UI aspect is closed source, but the computation engine, the editor, and part that gets MathJax working well in react native is open source at https://github.com/jacobp100/technicalc-core

I've just released an update for the iOS version of my app, TechniCalc.

It's a scientific calculator aiming to provide a comprehensive math feature set while not compromising on the user interface. I found too many apps had a great story for one half of that, but fell short on the other.

The app itself is React Native. The calculation and editor logic are in ReScript, and this part is open source too! (if you're interested - https://github.com/jacobp100/technicalc-core)

I'd love to hear all your feedback!

I’m working on a scientific calculator app - TechniCalc

It’s done in react native and a good amount of it is also open source.

It at least covers App Store fees

I wrote a PPPoE client with failover so I can keep the session even when one of my gateways fails or is rebooted (this lets me do regular maintenance without interrupting my internet connection); I put it on github[1], but I doubt anyone will use it. I hope there are few people left with the scourge that is PPPoE, and my OS choice means many people would need to switch OSes to use it, so yeah. Also, I don't care to make it easy to use or to promote it, really. (I've mentioned it once or twice and did a Show HN that got less than ten votes, which I kind of expected).

I've also got my personal (network) monitoring software, some 'IoT' stuff to capture temperature and humidity data around my house, and I'm working on a ESP32 based alarm clock pulling data from iCalendar.

I just published https://github.com/russor/ppp_thing which lets me (and maybe you) failover my PPPoE session between two FreeBSD hosts, so I can do regular maintenance without losing my IP or impacting TCP sessions.

I used to let my DSL modem handle PPPoE and NAT, so failover was easy, but found out fragmented IPv6 crashed the leased modem, and the replacement modem also sucks, so bridge mode + a custom PPPoE client (but from netgraph pieces) it is. Sadly useful in 2021, because PPPoE is somehow still a thing.
