SUMMARY A hand-check of the 15,000 images in the widely used Udacity Dataset 2 found problems in 4,986 of them (33%), including thousands of unlabeled vehicles, hundreds of unlabeled pedestrians, dozens of unlabeled cyclists, and 217 completely unannotated images that contained real objects. Phantom annotations…
In 2015 we ran 56,224 hard drives in our datacenter. In this post we review the reliability of the Seagate, HGST, Toshiba, and Western Digital drives.

One of the many enjoyable things about databases is that they generally try to separate how data is represented internally (say on disk) from how it is used. To the point that it has become the norm to not even store the data on the same hardware that is running the queries.
After being left for dead, SQL is making a comeback and the NoSQL vs. SQL debate is stronger than ever. Why? And how will it impact the data community?
turbopuffer is pushing the frontier of search. To do that, we have to fundamentally redesign our storage architecture so the vector index is no longer primary.

Your product's core abstractions determine whether new features compound into a moat or just add to a feature list. Here's how to get it right.
SQL's UNION operation isn't usually regarded as a way to optimize query performance, but in many cases it can be used to achieve massive improvements in speed.
Datomic is a general-purpose database intended for systems of record. In many ways, Datomic is unusual. At any instant in time, the state of the database is represented by a set of [entity, attribute, value] ( EAV ) triples, known as datoms . Each datom declares that some entity (like a person) has a particular…
I wanted a dinner recommendation and got a research agenda instead. Using 13000+ restaurants, I rebuild its ratings with machine learning and map how algorithmic visibility actually distributes power.
What is machine learning? See how it works with our animated data visualization.
It has recently been brought to our attention that the MySQL man pages have been relicensed. The change was made rather silently going from MySQL 5.5.30 to MySQL 5.5.31. This affects all pages in the man/ directory of the source code. You can tell the changes have come during this short timeframe (5.5.30->5.5.31). The…
