Google details new 24-hour process to sideload unverified Android apps

https://cdn.arstechnica.net/wp-content/uploads/2026/03/developer-identity-hero-640x360.jpg
Google is introducing a developer verification program to combat malware on Android devices, requiring verified developers to provide identification and pay a $25 fee. Power users can bypass this verification through an advanced flow in developer settings, but it's not immediately accessible and has a 24-hour countdown.

Full Disclosure: A Third (and Fourth) Azure Sign-In Log Bypass Found

https://trusted-sec.transforms.svdcdn.com/production/images/Blog-assets/FullDisclosure34_nyxgeek/Fig03_nyxgeek_GraphGoblin.png?w=320&q=90&auto=format&fit=max&dm=1773771018&s=2586c9d769ef6d03604c4c012a69f707
Nyxgeek discovered four Azure Entra ID sign-in log bypasses in the last three years, including GraphNinja, GraphGhost, GraphGoblin, and a fourth bypass involving a long user-agent string. These bypasses allowed attackers to validate passwords without generating log entries, and Microsoft fixed them in record time, but initially downplayed the severity of the issues.

Be intentional about how AI changes your codebase

To maintain a well-structured codebase, use semantic functions as building blocks that are minimal, self-describing, and unit-testable, and pragmatic functions as wrappers around complex logic. Effective data modeling involves enforcing correctness, using precise names, and avoiding loose typing to prevent bugs and make code easier to understand and maintain.

Linux Page Faults, MMAP, and userfaultfd for faster VM boots

https://www.shayon.dev/page-fault.jpg
Linux handles page faults through demand paging, where physical allocation is deferred until the page is actually touched, and userfaultfd lets userspace take over fault handling by intercepting and resolving page faults. Userfaultfd preserves the mapping identity, allowing KVM memory slots, VFIO DMA, and vhost-user shared memory to continue working as if the pages had always been present, ...

From Oscilloscope to Wireshark: A UDP Story (2022)

https://www.mattkeeter.com/blog/2022-08-11-udp/probes.jpg
The user decoded UDP packets from raw voltage waveforms captured by an oscilloscope connected to a high-speed active differential probe soldered to a rack switch. They implemented a parser to extract the packets from the waveform data, which involved decoding QSGMII protocol and rate adaptation to convert the data into conventional Ethernet packets.

How many branches can your CPU predict?

Scaling Karpathy's Autoresearch: What Happens When the Agent Gets a GPU Cluster

https://blog.skypilot.co/scaling-autoresearch/assets/banner.png
We used Claude Code to automate neural network training with 16 GPUs on a Kubernetes cluster, achieving a 2.87% improvement in val_bpb and discovering a strategy to exploit performance differences between H100 and H200 GPUs. The agent ran for 8 hours, submitting ~910 experiments and finding that scaling model width mattered more than any single hyperparameter, with a total cost of under $300.

NanoGPT Slowrun: 10x Data Efficiency with Infinite Compute

Researchers achieved 10x data efficiency with NanoGPT Slowrun by ensembling 1.8B parameter models and applying architectural tweaks. This allows scaling with compute rather than data, potentially leading to significant model performance improvements.

Kin: Semantic version control that tracks code as entities, not files

https://raw.githubusercontent.com/firelock-ai/kin/main/.github/kin-demo-terminal.svg
Kin is the semantic system of record for software work. It replaces the file-first, diff-first repository model with a graph of semantic entities and relationships, then serves precise context to AI agents and developers. Kin is not a coding assistant or a Git wrapper -- it is a sovereign VCS and the semantic operating layer that any assistant can use. kin init works with or without .git. ...
