I implemented various pieces of flight software for the Cargo Dragon space capsule, and to a lesser extent the Falcon 9 rocket. I got to be on a mission control shift for the C2 mission that first berthed with the International Space Station. Some of the software framework I wrote back then ended up getting used in Starlink despite having never worked on it directly, so I can say I have code orbiting the Earth on sev…

Created an account for this: would you be willing to share a bit more details about the autonomous aircraft carrier? Is an area I am extremely interested in. Perhaps a link? Many thanks!

Earlier quoted context omitted.

Thanks, I have put a non-trivial amount of thought into making the interface friendly. I appreciate the compliment :) I've got a staging environment at dev.parabible.com with other versions (it's a bit rougher and can break, but it supports searching in Greek along with a bunch of other translations). I've also added Apostolic Fathers there (which, I believe, is the first place that Ap. Fathers have been available in…

That's a nice, beautifully-rendered project. I winced when you mentioned copyright. On my sites (eg GiveThemLife.com), I try to avoid copywritten material in on-site content. I can't tell people it's free for any use if my dependencies might not be. That God gave us His Word as a free gift, but His children restrict it, just bothers me. I'm so grateful for MPJ and others who made the World English Bible. It's good en…

On the upside, many of the newer translations are corrupted, so the copyright may work to filter those out more easily

Most impactful, in order: 1. Was the intern that coded the mechanism to open/close the LIDAR cover on the Mars Phoenix Lander, so it runs on another planet. I also did circuit work, and other tasks for the CSA’s contribution to that mission. That was also the internship where I (re)met my wife. 2. Was on the Android team that brought video to Instagram back in 2013. We brought gyro stabilization to the iPhone, couldn…

PhD?

I had the fortunate opportunity to work with a really good, and relatively small group of developers to build the in-store point-of-sale system for Starbucks, used by over 12,000 US-based Starbucks and many internationally including in China. It is a hybrid on-prem and cloud based system, relatively simple architecture, yet quite scalable

Is this a startup? Does it have a name?

Yes, the startup was named Go Moment. Got acquired a year ago by one of the world's largest hotel tech companies (Revinate) where Ivy continues to grow and serve more guests. More info at https://rajsinghla.com/about

That is awesome. Great work.

Thank you for the kind words. Hotel tech/travel tech is a crowded and tough space to build in. Rewarding to see things work better for real people though!

About 25 years ago, with a group of friends: https://www.srcf.net/ It was what you'd call a community-run webhost, but at a time when such things weren't common. The main innovation was making it easy for multiple people to administer and hand over websites: we'd noticed that student society websites tended to get lost or rebuilt every year, because they were run under people's personal accounts which stopped working…

Thank you! The SRCF is incredibly useful. Long may it continue.

I started an airplane turbulence forecasting website for nervous travelers back in 2005 (think - will it be bumpy when I take my flight from Chicago to New York tomorrow?). It started by repackaging government turbulence maps in an easy to use manner, and has evolved into a service where I handwrite forecasts of turbulence for your flight, and now offering automated turbulence forecasts. It has been used by employees…

That's wonderful! How accurate are the forecasts overall?

While nothing is 100%, I've definitely had a few emails saying "the captain said so and so, but in the end you were right." I use the same maps and data that most of the airlines use (outside of any proprietary data that some airlines (but not many) have).
