Asynchrony is not Concurrency

Asynchronyisn't a twin toConcurrencyin Zig. It juggles async tasks without leaning on multi-threading, letting sync and async mingle harmoniously. Concurrency craves overlap, but Zig's savvy. When resources get stingy, it smartly reverts tasks to synchronous, dodging drama like deadlocks or sudden c.. read more

Understand CPU Branch Instructions Better

Branch prediction matters. Why? About a quarter of instructions are branches, and modern CPUs nail an accuracyabove 90%. Yet, those often-pesky branches can choke CPUs, stalling instruction flow. So, take a wrench to yourif-else logic. Trim indirect branches whenever you can—your CPU will thank you... read more

Containers: Everything You Need To Know

cgroupsand namespaces anchor Linux containers, isolating resources and processes like gatekeepers with a mission. On macOS and Windows, these containers ride in VMs withWSL2orLinuxKit, putting on their "welcome to the virtual world" hats. EnterrunC, executing OCI-built images with isolation flair, w.. read more

Crawling a billion web pages in just over 24 hours

Imagine tearing through1 billion pages in a single dayon a shoestring budget. This crawler pulled it off with12 nodes and some savvy async maneuvering. But here's the kicker: it wasn’t the fetching that choked the CPU. Nope, it was the parsing. Today’s web behemoths, bloated with JavaScript and othe.. read more

Lessons from scaling PostgreSQL queues to 100K events

PostgreSQLjuggles 100,000 events per second. Just needs some index wizardry and query twerking. The problem? Table bloat and Write Amplification. Gross. Enter the mightyCOPY—it bulldozes through bulk data, politely ignoring the usualInsertdrag. And those recursiveCTEs? They pull off loose index scan.. read more

Parsing 1 Billion Rows in Bun/Typescript Under 10 Seconds

Buntries to swallow files over 4GB and promptly chokes. The culprit? ItsBuffercaps out at 4GB. The fix? Slice files into chunks under 4GB but keep the buffer lean, no more than 128KB, to keep things zippy. Pull out the big guns—workers. This move fires up all CPU cores, slashing processing time from.. read more  

Parsing 1 Billion Rows in Bun/Typescript Under 10 Seconds
Kata Containers is a Cloud Native Computing Foundation (CNCF) project designed to close the security gap between traditional Linux containers and virtual machines. Instead of sharing a single host kernel like standard containers, Kata Containers launches each pod or container inside its own lightweight virtual machine using hardware virtualization.

This approach dramatically reduces the attack surface and prevents container escape vulnerabilities, making Kata ideal for multi-tenant, untrusted, or sensitive workloads. Despite using VMs under the hood, Kata is optimized for fast startup times and integrates seamlessly with Kubernetes through the Container Runtime Interface (CRI), allowing it to be used alongside runtimes like containerd and CRI-O.

Kata Containers is commonly used in scenarios such as multi-tenant Kubernetes clusters, confidential computing, sandboxed AI workloads, serverless platforms, and agent execution environments where strong isolation is mandatory. It supports multiple hypervisors, including QEMU, Firecracker, and Cloud Hypervisor, and continues to evolve toward faster boot times, lower memory overhead, and better hardware acceleration support.
