By Jose Fernandez , Ed Barker , Hank Jacobs Introduction In November 2022, we introduced a brand new tier — Basic with ads. This tier extended existing infrastructure by adding new backend components and a new remote call to our ads partner on the playback path. As we were gearing up for launch, we wanted to ensure it would go as smoothly as possible.

Kubernetes adoption survey executive summary. Modern, cloud-native computing is impossible to separate from containers and Kubernetes adoption. While Kubernetes is still a relatively young technology, a large majority of global enterprises use it to run business-critical applications in production. The rapid adoption is driven—and challenged by—an ever-growing ecosystem of Kubernetes technologies that add advanced platform features, such as security, microservice communications, observability, s

If you use Windows, you will want to monitor Windows Events. A recent contribution of a distribution of the OpenTelemetry (OTel) Collector makes it much easier to monitor Windows Events with OpenTel. You can utilize this receiver either in conjunction with any OTel collector: including the OpenTelemetry Collector. In this article, we will be using observIQ’s distribution of the collector.

Picture by Adrian — Ka’anapali sunset 2023 There’s been a lot of discussion about platforms recently, I talked about why I think it’s a current hot meme on the WTF Podcast with Charles Humble recently, and Sam Newman just wrote a blog post “ Don’t call it a platform ”. What I want to cover in this blog post is how I think platforms should be structured, and why it’s always plural, there isn’t one platform or one platform team.

Kubernetes is a widely used open source system for container orchestration. It allows for seamless running of containerized workloads across different environments. However, managing Kubernetes optimally can be a daunting task due to its complex architecture. Properly monitoring a Kubernetes cluster or any related environment can be difficult. Effective resource provisioning and management is a critical aspect of a Kubernetes cluster.

At the time of writing, 99.9% of pages on the web include at least one image. The median image-weight per page landed at 881KB in 2022 , which is more than HTML, CSS, JS, and fonts combined! And while images do not block rendering (unless you do something silly ), it’s important to consider how we offer a reasonably pleasant experience while users are waiting for images to load.

A few weeks ago, I saw a tweet that said “Writing code isn’t the problem. Controlling complexity is.” I wish I could remember who said that; I will be quoting it a lot in the future. That statement nicely summarizes what makes software development difficult. It’s not just memorizing the syntactic details of some programming language, or the many functions in some API, but understanding and managing the complexity of the problem you’re trying to solve.

Becoming a good engineer is about collecting experience. Each project, even small ones, is a chance to add new techniques and tools to your toolbox. Where this delivers even more value is when you can solve problems by pairing techniques learned on one project with tools learned working on another. It all adds up.

I tend to launch most programs on my Windows 10 laptop by typing the <Win> key, then a few letters of the program name, and then hitting enter. On my powerful laptop (SSD and 32 GB of RAM) this process usually takes as long as it takes me to type these characters, just a fraction of a second. Usually. Sometimes, however, it takes longer. A lot longer.

Bloom filters are an essential component of an LSM-based database engine like MyRocks. This post will illustrate through a simple example how bloom filters work in MyRocks. Why? With MyRocks/RocksDB, data is stored in a set of large SST files. When MyRocks needs to find the value associated with a given key, it uses a bloom filter to guess if the key could potentially be in an SST file.
