Salvatore Sanfilippo, aka antirez released a telegram bot library in C recently. While I'm not at all interested in a telegram bot library, I always like to read Salvatore's code, which is uniformly superb.
Everybody counts, but not always quickly. This post looks into how the PostgreSQL database optimizes counting. In Postgres, there are ways to count orders of magnitude faster. We’ll look at exact counts (distinct counts) as well as estimated counts, using approximation algorithms such as HyperLogLog (HLL) in Postgres.
Support for spatial data and geospatial indexing is one of the most requested features in the history of CockroachDB.
TaBERT is the first model that has been pretrained to learn representations for both natural language sentences and tabular data.

I recently wrote a post to announce the availability of M6g, R6g and C6g families of instances on Amazon Elastic Compute Cloud (Amazon EC2). These instances offer better cost-performance ratio than their x86 counterparts. They are based on AWS-designed AWS Graviton2 processors, utilizing 64-bit Arm Neoverse N1 cores…

As steer and drplokta pointed out yesterday , the Nielsen diagram was grossly out of proportion, so it looked like RIM and MS were better than they were. I passed the data to steer, who then played around with R (code is in the other post), and produced the second diagram. I've tried to line them…
We believe that charts with two different y-axes make it hard for most people to intuitively make right statements about two data series.
I’m a huge proponent of designing your code around the data, rather than the other way around, and I think it’s one of the reasons git has been fairly successful… I will, in fact, claim that the difference between a bad programmer and a good one is whether he considers his code or his data structures more important…
