Hobbyist uses voltage glitching to unlock A100 features on a mining card

·1 views

A blog post describes an experiment in which the author applied voltage glitching to a cryptocurrency mining GPU to re-enable capabilities associated with NVIDIA's A100 data center accelerator. The write-up is hosted on the author's personal blog and was shared on Hacker News, where it gathered 14 points and 2 comments. Mining cards are typically hardware variants with certain functions restricted, and the technique aims to bypass those limits through precisely timed power disturbances. The article details the method and its outcome, though the source material provided here contains only the link and metadata rather than the full text.

osFoundry adds a prompt library with versioning and reusable skills for agents

osFoundry, a desktop app combining chat, agents, files and tools, now includes a Prompt Library that gathers prompts in one searchable place with favorites and usage counts. Users can save edits either by overwriting a prompt or as a new version, keeping earlier wording available for reuse. Prompts can contain placeholders such as {{product}} that the app fills in through a simple form before inserting the text into the chat. Proven prompts can also be converted into skills in Studio, which agents use automatically when a task matches their trigger and assigned tools.

Testing a pump underload detector before it controls a motor

A running pump may draw less current when it loses load, but a low current reading alone cannot confirm a dry pump, so the detector should report suspected underload with supporting context. Measurements should begin only after the motor is confirmed running and the startup window has passed, and mismatches between run commands and contactor feedback should be logged. Missing, stale, or invalid current data should be treated as a sensor fault rather than as zero current. The alert should use its own persistence timer and reset when readings return to normal, while latched alarms, motor-stop logic, and protection hardware remain independent of the telemetry. Validation should involve replaying simulated traces, comparing results against normal operation at several operating points, and logging timestamps, RMS current, motor state, thresholds, and fault reasons.

Solana token rules can be verified with a single RPC call, no SDK needed

A developer published a method for reading a Solana token's rules using one standard RPC request, requiring no SDK, wallet, or keys. The approach decodes the token's mint account to reveal its owner program, mint and freeze authorities, and Token-2022 extensions such as transfer fees, transfer hooks, and permanent delegates. The author applies the check weekly to one token and says it recently corrected earlier documentation that had misstated the token's technical setup. Using the method on the WEN mint, the author found it runs on the original SPL Token program with authorities revoked and no extensions. The post argues that repeatable, rerunnable checks provide stronger evidence than one-time snapshots.
