Years ago, during the start of covid, I wanted to replicate the Arduino magnetic levitation system I saw my colleague build back in 2009. I know almost nothing about electrical engineering or control systems and when I tried this in 2020 I wasn’t even close to making it work. But now armed with LLMs, a 3D printer, and a willingness to buy whatever was needed from AliExpress I made the magnet fly!…
On a few occasions I’ve been fortunate enough to live within biking distance of a surf break. One of my favorite activities to do in this situation is outfit a bicycle with a surfboard rack and use it for transportation to the beach. Here are the bikes. PVC construction inspired by http://www.rodndtube.com/surf/info/surf_racks/BicycleSurfboardRack.shtml. GT Karakoram – 2007 I got this bicycle for…
I finally got around to enabling https here. Some notes: Namecheap sells ssl certs via PositiveSSL/Comodo. I thought this would be easiest but they don’t really work with AWS. I’ll never get that $7 back It’s more work to import a 3rd party certificate vs. creating one on AWS After importing the 3rd party certificate (which has to happen in N. Virgina) AWS still claims that it’s not from a trusted…
First post in 5+ years! I used to use s3_website to publish this blog. Turns out that project has been deprecated with nothing to replace it. Oh well. Following this I’ve managed to setup Github Actions to build/deploy the blog. A few small changes:

Check out this video of my talk at the NYC Machine Learning meetup. It’s based on this blog post and the deck is here.
Here’s a plot of the cumulative number of upvotes per minute for submissions to a few major subreddits:
Last year Chris Whong used a foil request to obtain a dataset with information on the locations, times, and medallions for 173 million NYC cab rides. I’m interested is determining which cabs are the fastest cabs are and how quickly they can get between various parts of the city.
Originally published on the Clarifai blog at http://blog.clarifai.com/what-convolutional-neural-networks-see-at-when-they-see-nudity/ Last week at Clarifai we formally announced our Not Safe for Work (NSFW) adult content recognition model. Automating the discovery of nude pictures has been a central problem in computer vision for over two decades now and, because of it’s rich history and…
The Evolution darknet marketplace was an online black market which operated from January 2014 until Wednesday of last week when it suddenly disappeared. A few days later, in a reddit post, gwern released a torrent containing daily wget crawls of the site dating back to its inception. I ran some off-the-shelf affinity analysis on the dataset – here’s what I found: Products can be categorized based…
