Hello peeps,

Sorry for the absence of newsletters last week. I (Alex) was on a one week beach holiday, soaking up the sun, salt, and sounds of the ocean. Don't have anything exciting to mention at the start of this week since I spent most of my time at the beach practicing my Russian reading Russian fantasy or soaking up that vitamin D. Anyway, there's an exciting week of articles to look forward to, so let's dive right into it.

Lambda functions and/or closures allow you to inline a function without much hassle. They haven't always been around though, and over the years languages have added more features for using them. In this concise article, Bartlomiej Filipek highlights the changes made to lambda functions in C++11, 14, 17, and 20. Bartlomiej specifically focuses on the elements that make up the lambda function call and provides examples of what would work, what wouldn't and why.

SQL has some pretty esoteric functions. They're really handy though for that 1 out of 100 use case situations though, especially if you're looking to optimize something. Lukas Eder has written an article that explores of these hidden SQL gems in the form of the NATURAL JOIN. Lukas explains how it can help you optimize table comparison, since most other solutions require accessing the tables multiple times, whereas with NATURAL JOIN, you only need one. Lukas also provides an alternative solution if you have pesky NULLs.

Multi-Threading in C/C++: Implications on Software Library Design

(Mar 04) #cpp Save to Pocket

Optimization has been moving more and more towards parallelization as hardware performance has been gradually stagnating. Although this article is from a while back, Karl Rupp does a good job of demonstrating timeless good practice principles; keep your library code flexible and convenient for the user. Karl explains these principles in the context of parallelizing in C++11 and the inconvenience of libraries forcing users to choose between multi or single threading in their applications.
