Your CI pipeline is the slowest engineer on the team (Sponsor)
Most CI platforms make you choose: flexibility or scale. Jenkins eats your weekends. GitHub Actions sends you a bill that scales faster than your test suite.
Buildkite runs agents on your infra or theirs used by Shopify, Canva, and teams at 100,000+ concurrent agents. Here's what you get:
- Pipelines across any language, cloud, or runner self-hosted or managed
- Test Engine with flaky test detection, auto-quarantine, and test splitting
- Package Registries to cache dependencies and lock down your supply chain

First public macOS kernel memory corruption exploit on Apple M5 (7 minute read)
Researchers successfully developed the first public macOS kernel memory corruption exploit targeting the new Apple M5 silicon despite its advanced hardware-based security features. This breach bypassed the Memory Integrity Enforcement system, a multi-billion-dollar defense mechanism designed over five years to make such memory-based attacks obsolete. However, Anthropic's Mythos Preview model was used to find and exploit these vulnerabilities in just five days.
Adopting Herb at GitHub (9 minute read)
A staff engineer integrated Herb, a C-based parser for HTML+ERB templates, into a Rails monolith with ~500K lines of ERB to help validate it before it potentially replaces Erubi in Rails core. It caught real bugs existing linting missed (malformed HTML and invalid Ruby in untested branches), and AI assistants one-shot fixed most of the ~2,800 failing files.
IC work is the new career flex (14 minute read)
High-level professionals are increasingly shifting toward high-impact individual contributor roles to deliver full end-to-end business value without the burden of high team coordination costs. This is because AI acts as a force multiplier, allowing a single person to perform cross-disciplinary tasks and allowing companies to flatten organizational structures by rewarding direct business impact over headcount size.
What to do if you're not "detail oriented" (10 minute read)
Producing error-free work is necessary for knowledge workers because sloppiness erodes trust and credibility, meaning employees must own every task and not rely on managers or customers to catch mistakes. To overcome a lack of natural detail-orientation, implementing systems like checklists and formatting tools can effectively prevent small errors from becoming career blockers.
The context layer for modern engineering teams (Sponsor)
Agents can generate code. Getting it right for your system, team conventions, and past decisions is the hard part. Unblocked is the context layer that turns code, docs, tickets, and conversations into actionable context, so engineers move faster and agents stay on track.

Did capacity shortages turn Anthropic hostile to devs? (8 minute read)
Anthropic recently faced backlash for restricting developer features and banning accounts, moves that were likely desperate measures to manage usage growth that far exceeded initial capacity plans. To resolve these infrastructure shortages, the company has reached an agreement to lease data center space from xAI, which will allow for increased API rate limits and restored access for Claude Pro subscribers.
Why are AI companies buying the teams behind your favorite dev tools? (6 minute read)
AI labs are acquiring development tool teams to secure the infrastructure, like package managers and runtimes, that their coding agents rely on to function. Developers should use these tools while avoiding platform-specific coupling and tracking shifts in maintainership.
Reveal: an SDK to add secure and controllable analytics to your product in weeks (Sponsor)
SaaS teams using Reveal ship analytics features without standing up a dedicated BI team. One SDK install, your existing auth, your existing infrastructure, your branding.
