When I was talking about monitoring web performance yesterday, I linked to the CrUX data for The Session. CrUX is a contraction of Chrome User Experience Report. CrUX just sounds better than CEAR. It’s data gathered from actual Chrome users worldwide. It can be handy as part of a balanced performance-monitoring diet, but it’s always worth remembering that it only shows a subset of your users; those on Chrome. The actual CrUX data is imprisoned in some hellish Google interface so some kind...| Adactio: Journal

Ever since the introduction of Bun there are three runtimes to choose from when wanting to develop and run a JavaScript server.

When a rider takes a trip, Uber collects money primarily through the rider’s preferred payment method linked to their Uber account, with the fare collected upon trip completion. In some markets, cash payments are also an option, with riders paying the driver in cash at the end of the trip. A chargeback is a dispute filed by a rider through their bank or credit card issuer. Chargebacks typically arise due to suspected fraud or service-related issues. Most service-related disputes are further...| Uber Blog

I am always fascinated by how us technologists can’t leave our backends out of API discussions. Keeping an API design conversation just about the interface between a producer and consumers proves to be one of the most difficult things about collaborating within or across teams. Sure, there are plenty of backend concerns expressed in interfaces, but those things need to be abstracted away and distilled down into only what is needed for a single, or series of API transactions with consumers. ...| API Evangelist

Elixir in Action author Saša JurićIn the final article of this series we’ll take a look at our approach to testing at Very Big Things. As always, when discussing some practice or technique, it’s worth defining the purpose, i.e. the benefits that we want to reap. When it comes to tests, we write them to verify that the system is working as expected. A good test suite will fail when something is off in the behaviour of the system. If everything works correctly, all of the tests should p...| Very Big Things - Medium

Elixir in Action author Saša JurićThe previous article discussed the high-level design of Very Big Things’ projects. Today we’ll dive a bit deeper and take a look at the namespace structure. The word namespace here refers to dot-separated module names.

Likewise, MySystemWeb is another namespace, containing modules such as MySystemWeb.Endpoint, a...| Very Big Things - Medium
Elixir in Action author Saša JurićIn my previous article, I presented the development process used at Very Big Things. Now it’s time to turn our attention to the code.

To do our job efficiently we need our environment to be well organized. In development, this is the role of code design.| Very Big Things - Medium
