Hiring one mechanical, electrical or embedded engineer takes roughly 40 hours of senior engineering time across phone screens, take-home reviews and onsite interviews, according to Colare, the San Francisco startup that raised a $2.5 million pre-seed round from Afore Capital, Garage Capital and Acadian Ventures .

A round two engineering report on brute force detection, a deployment that works, a GPU module that does not yet exist, and the experiment that would settle whether decentralized compute earns a place in this pipeline. The problem is context, not collection Most security teams do not lack events. They lack the story that connects them. A failed login at 02:14, a success at 02:19 from the same address, and a read of a sensitive resource at 02:21 are three log lines in three systems.

Every model review I have sat in eventually arrives at the same slide: one big number in a large font. Accuracy 92%. F1 0.88. AUC 0.91. Heads nod. Someone asks about latency—the model ships. The problem is not that the number is wrong. The problem is that it answers a question nobody actually asked.

Every financial instrument looks sound until the day it is asked to perform under pressure. Stablecoins have not had that day yet. That is the core message of a new report from the Financial Stability Board, the body that coordinates financial regulation for the G20. The FSB found that global stablecoins have not been tested under severe stress or insolvency. It also found that the national rules meant to govern them are developing at different speeds. The result, in the FSB’s view, is a gap.

Most AWS bills I audit are not bloated because of exotic architecture mistakes. They are bloated because of a dozen boring defaults nobody revisited: on-demand pricing for steady workloads, gp2 volumes, log groups that never expire, S3 buckets with no lifecycle rules, NAT gateways carrying traffic that should never touch them. Below are 20 fixes, grouped by where the money leaks, each with a realistic savings range, a worked example, and — where it helps — the exact CLI command or config.

More than half of all web traffic in 2024 wasn't human. The Imperva bad bot report found that automated traffic overtook people for the first time in a decade, and a meaningful share of that automation spends its time clicking, loading, and "viewing" ads that were never meant for an actual person. That's invalid traffic, and if you've ever run a paid campaign anywhere near the open web, it's already touched your budget whether you noticed or not.
