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.

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

Code coverage is a software quality metric commonly used during the development process that let’s you determine the degree of code that has been tested (or executed). To achieve optimal code coverage, it is essential that the test implementation (or test suites) tests a majority percent of the implemented code. There are a number of code coverage tools for languages like Java, C#, JavaScript, etc.

What would you say is the job of a software developer? A layperson, an entry-level developer, or even someone who hires developers will tell you that job is to … well … write software. Pretty simple. An experienced practitioner will tell you something very different. They’d say that the job involves writing some software, sure. But deep down it’s about the purpose of software.

The release candidate of OpenTelemetry metrics was announced earlier this year at Kubecon in Valencia, Spain. Since then, organizations have embraced OTLP as an all-in-one protocol for observability signals, including metrics, traces, and logs, which will also gain Dynatrace support in early 2023. Realizing the promise of OpenTelemetry is a challenge for most organizations.

As we are progressing with application development, among various things, there is one primary thing we are less worried about: computing power. Because with the advent of cloud providers, we are less worried about managing data centers. Everything is available within seconds on-demand. This leads to an increase in the size of data as well. Big data is generated and transported using various mediums in single requests.

Unless work is done per architecture to implement HAVE_ARCH_VMAP_STACK / CONFIG_VMAP_STACK, the Linux kernel defaults to two pages worth of stack per thread. Note: on many contemporary systems the page size is 4KiB, but this is actually configurable for many architectures. The trade offs probably require a separate post. If you see code that checks for alignment via bitwise tricks like addr & 4095 == 0 without checking sysconf(_SC_PAGESIZE) it is perhaps a red flag for code that might be to
