TL;DR I've missed a lot of opportunities simply because I didn't know they existed. So every...

Hey everyone! I bring you my development journey on what I have discovered, accomplishments for this...

👋👋👋👋 Looking back on your week -- what was something you're proud of? All wins count -- big or small...

I've been exploring some lesser-known languages and I'm curious what the community thinks. Languages like Go, Rust, and Kotlin have gained traction, but I feel like there are some gems that don't get enough attention. What programming language do you think is underrated? Which one deserves more love from developers? Share your thoughts and why you think that language is underrated!

We were burning 400ms in p99 tail latency on a core event-processing path in Veltrix. The upstream teams kept blaming the network, but the numbers didnt lie—64% of the time was spent inside the JVM, specifically in sun.misc.Unsafe.park during GC pauses. Every time we hit 80% heap pressure, the throughput collapsed and we lost 300k events per minute. That was the exact moment I stopped believing in the JVM as the runtime and started looking at the system boundary. The first attempt was aggressively tuned HotSpot with G1GC and pinning the critical threads to their own NUMA nodes. We set -XX:MaxGCPauseMillis=20 , -XX:+UseNUMA , and even migrated to Azul Zulu Prime because its handling of large heaps was supposedly better. The p99 dropped to 280ms, but the GC telemetry still showed a sawtooth pattern of 30–40ms spikes every 230ms on a 16GB heap. Profiling with JDK Flight Recorder told us 18% of CPU time was spent in card-table scanning. At that point I knew we were fighting the runtime, not the problem. The event pipeline was small—just JSON parsing, enrichment, and a single RocksDB write—but the JVMs generational collector couldnt stop moving objects. The architecture decision came during a four-day blackout window after a failed Blue-Green deploy. Three of us sat in a war room with a single Grafana dashboard showing 100% CPU steal time on the Kubernetes nodes. We had two choices: squeeze more life out of the JVM by manually balancing the heap or rewrite the critical hot path in Rust and give the compiler full control over memory layout. The Rust option meant losing the JVM ecosystem (no more async-profiler, no more one-liner heap dumps) but gave us stackless futures, zero-cost abstractions, and compile-time memory safety. We chose Rust. We forked the Cargo.toml wed used in a sidecar for metrics and started porting the event collector. The numbers after the rewrite told the story. We recompiled the same two endpoints— POST /events and GET /aggregates —and served them f

LinkerBot makes dexterous robotic hands for as little as $600. It wants to become the standard for humanoids and automated factories—and eventually replace human labor altogether.

A new hacking campaign is trying to trick Signal users to give up their secret recovery key, which can be used to access online backups containing past messages.

The launch of the Ojai minivan robotaxi comes after years of development and testing, but arrives amid a challenging time for Waymo.

The pale-blue Ojai vehicles will start picking up members of the public in California and Arizona today.

After several months of testing, Waymo is finally ready to invite non-employee passengers into its newest vehicle, the Zeekr RT minivan, which has been rebranded as Ojai. Waymo says it will begin offering "select riders" access in San Francisco, Los Angeles, and Phoenix, before "gradually" expanding to more riders and cities. Trips will be free […]
