The Syncplicity Desktop client. At the time, we were a major Dropbox competitor and an overall industry leader. I was able to make our desktop client faster than Dropbox and handle ~250,000 files.

Shortly after I left, Dropbox released their Rust-based client. I don't know how they compare.

The big complication in a product like this is the metadata. Things that might not seem like a big deal, like string comparisons, must be super-optimized.

Setting up an automated lecture capture system at my university, based around the open-source https://opencast.org software. We did everything from buying hardware components to build machines that were specifically tuned to encode videos on the fly with the least space/noise possible to be put into lecture halls, writing the software to run on that, to running the video management system with opencast, integrating it with e-learning suites, setting up livestreams, etc.

I left the university and that job exactly one year before COVID-19 hit, and as far as I heard having that system in place saved a lot of butts - lectures seamlessly shifted to fully virtual with teachers recording videos either at home or in empty lecture halls, and pushing it through these video management systems.

We pushed a lot in 2015 to get approval for this whole endeavour, even though the university big-wigs pushed heavily against this, fearing that students would not come to lectures anymore. Turns out: that fear was bullshit, and in the end it helped out a lot of people.

Let's Encrypt (along with the coauthors of https://abetterinternet.net/documents/letsencryptCCS2019.pdf and many other contributors). Now the world's largest public certificate authority!

Thank you so much for this! I use it on my personal site and it was as simple as configuring a few cron jobs!

Two things for me. An electromagnetics finite element analysis package that was then used to design the actuators for the landing gear for the 737NG-series; where millions of people’s lives have depended on that landing gear working. And the coupling filters for the HF amplifiers in the Australian over-the-horizon radar array.

In all these I was only part of the project, but everyone’s work added up.

Co-created Dall-E Mini (now named Craiyon, and I am not involved anymore). It was among the first text to language models created independently. And it was fully open source. It also got covered by New York Times in the article covering Dall-E 2 by Cade Metz. Links: - GitHub: https://github.com/borisdayma/dalle-mini - Hugging Face Demo: https://huggingface.co/spaces/flax-community/dalle-mini - NYT article: https://ww…

Creating DALL-E Mini at 22 is a huge achievement, especially with less than two years of experience!

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 at nearly every airline, including dispatchers, flight attendants, captains, and I've gotten many emails saying it has allowed people to fly again, to take new jobs, and continue relationships because they know what to expect when they fly.

1: Porting YNAB from a spreadsheet to a C# Windows app back in 2006. (People tell us YNAB has changed their life) 2: Subsequently helping build the YNAB company/team. They are an amazing group of people and I’ll likely never be prouder of anything in my life. To be very clear: I can’t take credit for the original idea or spreadsheet. That would be our original founder, Jesse.

YNAB did change my life, thank you!

That means so much to me! Thank you for telling me!

Impactful? Designed and deployed credit card readers used in gas pumps back in 1979. (Sold to Gasboy) Wrote a fine tuner to allow communication between satellites (precursor to TDRSS days). Still used to this day. Failover of IP in ATM switches (VVRP, PXE, secondary DHCP, secondary DNS, secondary LDAP, secondary NFS). While not invented here, it is still used today as this is a Common setup to this day. Printer drive…

OMG, Who are you?
