The other day I was auditing a site and ran into a pattern that I’ve seen with a few different clients now. The pattern itself is no longer recommended, but it’s a helpful illustration of why it’s important to be careful about how you use preload as well as a useful, real-world demonstration of how the order of your document can have a significant impact on performance (something Harry Roberts has done an outstanding job of detailing ).

Programs, life cycles, and laws of software evolution , Lehman, Proc. IEEE, 1980. Today’s paper came highly recommended by Kevlin Henney and Nat Pryce in a Twitter thread last week, thank you both! The footnotes show that the manuscript for this paper was submitted almost exactly 40 years ago – on the 27th February 1980. The problems it describes though (and that the community had already been wrestling with for a couple of decades) seem as fresh and relevant as ever.

Dynimize, a dynamic binary optimizer, has been shown to improve MySQL performance in CPU intensive workloads. This post explores how Dynimize can be used to instantly reduce MySQL CPU usage without altering a single line of your application code or my.cnf. You notice that the Linux top command shows that MySQL is consuming a lot of CPU resources, and you're worried that you're not leaving this server with enough breathing room.

By Aditya Mavlankar, Jan De C**k¹, Cyril Concolato, Kyle Swanson, Anush Moorthy and Anne Aaron TL; DR We need an alternative to JPEG that a) is widely supported, b) has better compression efficiency and c) has a wider feature set. We believe AV1 Image File Format (AVIF) has the potential. Using the framework we have open sourced, AVIF compression efficiency can be seen at work and compared against a whole range of image codecs that came before it.

Functions are tested by feeding them input and examining the output, and the internal program structure is rarely considered.”. Functional testing is a Black Box technique in which the output is validated against the input provided to the application.
