What is infrastructure as code? Discover the basics, benefits, and best practices

Dynatrace

The IT world is rife with jargon — and “as code” is no exception. “As code” means simplifying complex and time-consuming tasks by automating some, or all, of their processes. ” While this methodology extends to every layer of the IT stack, infrastructure as code (IAC) is the most prominent example.

Develop Multi-Value Applications With Modern Source Code Managers

DZone

The legacy version control tools are specific to the multi-value programming controls BP libraries and DICT files on the PICK operating system environment. Checking out code from a BP Library is usually known as the locking process because files get locked by the developer for the time of their code change request.

Announcing bpftop: Streamlining eBPF performance optimization

The Netflix TechBlog

Striking a balance between eBPF’s benefits and system load is crucial, ensuring it enhances rather than hinders our operational efficiency. Introducing bpftop bpftop provides a dynamic real-time view of running eBPF programs. It displays the average execution runtime, events per second, and estimated total CPU % for each program.

Kubernetes Observability: Code Profiling With Flame Graphs

Percona

It shows which code paths are more busy on the CPU in given samples. An example of a flame graph can be found below: Each box is a function in the stack, and wider boxes mean more time the system was busy on CPU on these functions. Flame graphs are a graphical representation of function calls. ✔ Launching profiler.

Application observability meets developer observability: Unlock a 360º view of your environment

Dynatrace

Application observability helps IT teams gain visibility in their highly distributed systems, but what is developer observability and why is it important? The scale and the highly distributed systems result in enormous amounts of data. They also care about infrastructure: SREs require system visibility and incident management.

Fast memcpy, A System Design

ACM Sigarch

We look here at a Gedankenexperiment: move 16 bytes per cycle , addressing not just the CPU movement, but also the surrounding system design. The standard short move code tests that len is small, say < 16, and then does. The short plus medium code covers all lengths up to 255 bytes. Thought Experiment. Long Moves.
