We don’t have a useful quantum computer yet, but we do have quantum algorithms. Shor’s algorithm has the potential to factor large numbers faster than otherwise possible, which—if the run times are actually feasible—could break both the RSA and Diffie-Hellman public-key algorithms. Now, computer scientist Oded Regev has a significant speed-up to Shor’s algorithm, at … Read More “Improving Shor’s Algorithm” »

A helpful summary of which US retail stores are using facial recognition, thinking about using it, or currently not planning on using it. (This, of course, can all change without notice.) Three years ago, I wrote that campaigns to ban facial recognition are too narrow. The problem here is identification, correlation, and then discrimination. There’s … Read More “Facial Recognition Systems in the US” »

They’re short unique strings: Sqids (pronounced “squids”) is an open-source library that lets you generate YouTube-looking IDs from numbers. These IDs are short, can be generated from a custom alphabet and are guaranteed to be collision-free. I haven’t dug into the details enough to know how they can be guaranteed to be collision-free. As usual, … Read More “Friday Squid Blogging: Sqids” »

Wow: To test PIGEON’s performance, I gave it five personal photos from a trip I took across America years ago, none of which have been published online. Some photos were snapped in cities, but a few were taken in places nowhere near roads or other easily recognizable landmarks. That didn’t seem to matter much. It … Read More “AI Is Scarily Good at Guessing the Location of Random Photos” »

Artificial intelligence is poised to upend much of society, removing human limitations inherent in many systems. One such limitation is information and logistical bottlenecks in decision-making. Traditionally, people have been forced to reduce complex choices to a small handful of options that don’t do justice to their true desires. Artificial intelligence has the potential to … Read More “AI and Lossy Bottlenecks” »
