I used the hyperfine tool to measure the overhead of startup and shutdown of several code interpreters. Each interpreter was invoked with an empty string for evaluation. In few cases it was not possible, an empty file was passed as argument. This is more of a interesting experiment and presentation of hyperfine utility, and its plotting capabilities rather than a serious benchmark. The results should not be taken as an indication of "X is faster than Y". Here's the link to the repo with the code: Hyperfine Hyperfine is command-line benchmarking tool. It reruns the given commands multiple times ..read more

"When you combine two pieces of data you get data. When you combine two machines you get trouble." - Rich Hickey presenting The Functional Database. Concepts focused on functional programming, mainly on immutability, have been increasingly present in our daily lives, therefore, nothing more fair than getting to know a database whose philosophy is the immutability of data, bringing control of facts in a format completely different from what we are used to. In this article, we will get to know Datomic, which has this name precisely because it brings data in a format slightly different from the ..read more

The New Column API Today we at scicloj deployed a new Column API (tablecloth.column.api) into the data processing library Tablecloth (available as of version 7.029.1). This new API adds a new primitive to the Tablecloth system: the column. Here’s how we use it: (require '[tablecloth.column.api :as tcc]) (tcc/column [1 2 3 4 5]) ;; => #tech.v3.dataset.column<int64>[5] null [1, 2, 3, 4, 5] The new column is the same as the columns that comprise a dataset. It is a one-dimensional typed sequence of values. Underneath the hood, the column is just the column defined in tech.ml.dataset, t ..read more

The latest 0.1.11 release of PG2 introduces HugSQL support. The pg2-hugsql package brings integration with the HugSQL library. It creates functions out from SQL files like HugSQL does but these functions use the PG2 client instead of JDBC. Under the hood, there is a special database adapter as well as a slight override of protocols to make inner HugSQL stuff compatible with PG2. Since the package already depends on core HugSQL functionality, there is no need to add the latter to dependencies: having pg2-hugsql by itself will be enough (see Installation). Basic Usage Let’s go through a short de ..read more
