<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
AI models like ChatGPT optimize their performance using various layers, including a harness, API, and inference, to improve efficiency and reduce costs. They use techniques like persistent WebSockets, stable prompt prefixes, and parallel safety checks to minimize repetitive work and improve the overall processing speed of tasks.

<strong>GitHub is the wrong shape for this new world (7 minute read)</strong>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
The current software development landscape requires a reevaluation of collaboration tools like GitHub, as traditional paradigms are being overwhelmed by the velocity and scale of new contributions from various teams. To address these challenges, the focus should shift to developing high-throughput infrastructure primitives that improve software delivery processes.

<strong>New research: The Core Web Vitals thresholds you trust might be wrong for your site (6 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Google's 2.5s “good” LCP threshold comes from aggregated data across millions of sites, so it tells you nothing about where your own users actually start bouncing. Across ten major retailers, every single one hit its best bounce rate somewhere between 100ms and 1 second, well before that line. Four of the ten had already flattened out onto the performance plateau before reaching 2.5s, meaning they were technically “good” for Google while having stopped gaining anything from speed a while back.

More than half of AI unicorns valued at over $1 billion have never published a scientific paper or preprint. A small number of these firms dominate academic citations, with OpenAI accounting for a significant share of them, while others prioritize fast-paced, informal disclosure methods over formal publications.

<strong>Contagious Interview malware in SVG images: DPRK campaign (9 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
DPRK-aligned actors are handing developers fully-functional “coding challenge” repos, one seeded through Elastic's own community Slack #jobs channel, with the payload split into Base64 chunks hidden in HTML comments across SVG flag images. It is reassembled and executed on every npm run dev or npm start. What lands is a four-module OTTERCOOKIE stack: browser credential and crypto wallet theft, a recursive sweep for .env files, SSH/AWS configs and shell histories, a Socket.IO RAT with live shell access, and a clipboard stealer.
