<li><strong>Python 3.15 JIT compiler hits performance goals early</strong>: The CPython JIT compiler for Python 3.15 alpha has exceeded its performance targets, delivering up to 12% speedups on macOS AArch64 and 6% on x86_64 Linux. A core contributor noted that a rewritten tracing frontend using a dual-dispatch mechanism significantly increased JIT code coverage. This milestone was achieved despite the Faster CPython team losing its primary sponsor earlier in the development cycle. <a href="https://app.daily.dev/posts/MhtooSety" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Critical supply chain attack hits litellm on PyPI</strong>: A malicious version of the litellm package (1.82.8) was briefly published to PyPI, capable of exfiltrating SSH keys, cloud credentials, and Kubernetes configurations. The attack, which affected transitive dependencies like dspy, was discovered when a developer’s machine crashed after installing the package via a Cursor MCP plugin. Users are urged to rotate all credentials and audit CI/CD secrets immediately. <a href="https://app.daily.dev/feed-by-ids?id=9roAdsa2z&amp;id=FiWEwF4WD&amp;id=xt7JWjaFB" target="_blank" rel="noopener nofollow">Read more</a></li>

<h2>Bullshit police</h2>
<ul>
<li><strong>The Delve compliance fraud scandal</strong>: Y Combinator-backed startup Delve is accused of running a ‘Fake Compliance as a Service’ scheme, allegedly fabricating SOC 2 reports for hundreds of clients. Leaked data shows 99.8% identical boilerplate across audits, with evidence suggesting the use of Indian ‘certification mills’ to rubber-stamp security claims. If you used them, your HIPAA and GDPR compliance is currently a house of cards. <a href="https://app.daily.dev/feed-by-ids?id=48Uy5BKcM&amp;id=zmPU272WX&amp;id=S4r4Sj7sx" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>The AI data center capacity mirage</strong>: NVIDIA is currently selling GPUs for data centers that don’t actually exist yet, with only 33% of announced US capacity under active development. Critics argue the industry is systematically overstating progress to pump stock prices, creating a massive capital misallocation bubble. It turns out you can’t run a trillion-parameter model on a press release and a prayer. <a href="https://app.daily.dev/posts/X3my4Sf8s" target="_blank" rel="noopener nofollow">Read more</a></li>
<li><strong>Paying engineers in AI tokens</strong>: Jensen Huang is now suggesting that engineers should be paid in ‘AI tokens’ worth half their salary, a move critics call a transparent attempt to inflate compensation packages with non-vesting, non-appreciating company scrip. It’s not a bonus; it’s a high-pressure mandate to produce at ‘superhuman’ rates using the very tools that are being used to justify future layoffs. Welcome to the tokenized sweatshop. <a href="https://app.daily.dev/posts/Ryzsn8a9R" target="_blank" rel="noopener nofollow">Read more</a></li>
