·1 views

Hardware wallet manufacturer Ledger has confirmed the existence of an undocumented, or 'hidden,' chip within its security device. This confirmation follows allegations linking the component to reports of a $92 million cryptocurrency theft. The chip's undocumented nature means a portion of the device's security foundation is concealed and cannot be independently verified. Security experts warn such hidden components could create unauthorized pathways for data interception. The situation has intensified debates over transparency versus proprietary 'black box' designs in security-critical hardware.

AWS-managed keys fail HIPAA compliance, require customer-managed keys for breach response

A technical analysis highlights a critical compliance gap for healthcare data on AWS S3. Using AWS-managed encryption keys fails to meet strict HIPAA security requirements. Specifically, the HIPAA Breach Notification Rule's safe harbor provision requires the ability to immediately revoke access to encryption keys during an incident. With an AWS-managed key, users cannot disable or delete the key to contain a breach. Therefore, HIPAA workloads storing protected health information must use customer-managed keys to enable key revocation and pass compliance audits.

This distinction is critical for calculating burn rate and financial planning. Founders must track both the cost before credits and the credits applied to understand future funding requirements. Different cloud providers have varying terms for credit eligibility, expiry, and coverage restrictions.

Engineering article provides accurate formula for Klopper dished head volume

An article on DEV Community addresses common inaccuracies in calculating the volume of vertical stainless steel tanks. It focuses on the Klopper dished head, a specific torispherical shape defined by standards. The piece explains that engineers often approximate these heads as ellipsoidal or hemispherical, leading to significant volume errors. These miscalculations affect total tank capacity, headspace, and pressure equipment classification. The article provides a precise formula and a numerical example to demonstrate the correct calculation method.

AI tool streamlines public tender searches with fresh data and structured queries

A method using the Model Context Protocol (MCP) allows AI assistants to automate the search for public tenders. The system connects to live data sources, enabling assistants to fetch current notices at the time of a query rather than relying on stale, copied lists. It provides three core tools: one for searching tenders by country, sector, and keywords, and two others for listing valid countries and sectors to ensure accurate queries. This setup helps users, such as small businesses, efficiently find relevant opportunities by asking precise, structured questions. The final decision to bid on any tender remains with the human user.
