CSS Wizardry

APRIL 22, 2020

One of the more fundamental rules of building fast websites is to optimise your assets, and where text content such as HTML, CSS, and JS are concerned, we’re talking about compression. The de facto text-compression of the web is Gzip, with around 80% of compressed responses favouring that algorithm, and the remaining 20% use the much newer Brotli. Of course, this total of 100% only measures compressible responses that actually were compressed—there are still many millions of resources that could

Why Chaos Mesh? In the world of distributed computing, faults can happen to your clusters any time, anywhere. Traditionally we use unit tests and integration tests that guarantee a system is production-ready. However, these tests can’t cover everything as clusters scale, complexities mount, and data volumes increase by petabyte levels. To better identify system vulnerabilities and improve resilience, Netflix invented Chaos Monkey , which injects various types of faults into the infrastructure an

There is no faster (pun intended) way to slow down a site than to use a bunch of JavaScript. The thing about JavaScript is you end up paying a performance tax no less than four times: The cost of downloading the file on the network. The cost of parsing and compiling the uncompressed file once downloaded. The cost of executing the JavaScript. The memory cost.

Usually one would expect that ALTER TABLE with ALGORITHM=COPY will be slower than the default ALGORITHM=INPLACE. In this blog post we describe the case when this is not so. One of the reasons for such behavior is the lesser known limitation of ALTER TABLE (with default ALGORITHM=INPLACE) that avoids REDO operations. As a result, all dirty pages of the altered table/tablespace have to be flushed before the ALTER TABLE completion.

In extreme cases, there would be as many configuration variations as actual hosts. Modifying configurations manually via the UI for each and every host is time consuming, labor intensive, and error prone.
