THE HIDDEN LATENCY INSIDE YOUR DATABASE

Network-attached storage adds latency inside a database cluster, even when the application and database are close together. Local NVMe avoids that hop, but requires deliberate replication and failover to preserve durability. Workloads that fit mostly in RAM may see little benefit, while frequent cache misses and IOPS limits make storage placement worth examining.

JAILBREAKING MY CAR'S NAVIGATION SYSTEM JUST SO I CAN CHANGE THE TIME

A Renault's clock settings were inaccessible without a legitimate navigation SD card, turning a daylight-saving adjustment into a firmware reverse-engineering project. QEMU emulation exposed how a script parser's file writes and Linux's core-dump handling could combine into code execution. The eventual fix changed the stored GPS time offset from 180 minutes to 120.

RESISTING COGNITIVE SURRENDER

Uncritically accepting agent output can increase technical debt while eroding the understanding needed to debug and maintain a system. Choose how much to delegate based on risk, stay involved in consequential decisions, and ask for small, comprehensible changes. When delegating more fully, use independent observability, deterministic checks, and shadow traffic to verify behavior rather than relying solely on the agent's account.

AUDITIONING ENGINEERING: SOFTWARE ENGINEERING INTERVIEWS IN THE AGE OF AI

Warner Music Group encourages candidates to use AI while solving realistic API integration problems against a live, randomized test server. Its system-design interview asks candidates to modify an existing system and infer causes from observed behavior. The approach emphasizes technical judgment, although building new coding exercises and training senior system-design interviewers remain costly.

SPARKS OF WEIGHT-SPACE PROGRAMMING

Experiments show GPT-6 Astra reading and directly editing neural network weights without gradient descent, including writing small game-playing networks from scratch. Editing 0.016% of Qwen3.5-0.8B's weights reduced reasoning loops and raised MATH-500 accuracy from 7.9% to 48.1% with 50 forward passes for feedback. The gains removed an obstacle to existing ability, while similar edits failed to meaningfully improve a Gemma model that rarely looped.

COULD A MODERN CHESS ENGINE ON A PENTIUM HAVE DEFEATED KASPAROV IN 1996?

A port of Stockfish running on a 200 MHz Pentium Pro with 64 MB of RAM reaches a measured rating of 3180 at 30 seconds per move. The experiment attributes much of chess engines' progress to better search and evaluation rather than faster hardware. Its roughly 3300 rating at classical time controls is extrapolated from shorter games, and readers can play the machine online.

C++26 DIS FAILED, HOW DOES C++ SURVIVE?

C++26's draft failed its ISO ballot amid objections to Contracts, leaving the committee to agree on a revised path and putting the release schedule in doubt.
