There's a new way to break RSA that's faster than anything we've seen before

(5 minute read)Researchers have discovered a novel method that uses classical computing to reduce the current RSA security level to an unacceptably low threshold.

The technology involves signature forgery and reduces the required computing resources by orders of magnitude.

A new trend of CPU shortages

(10 minute read)Many companies are struggling to source CPUs. CPU spot pricing has disappeared because there's no longer any lack of demand for CPUs. It's now nearly impossible to get CPUs on spot instances without long-running connections with cloud providers. Reserving specific CPUs now needs to be done months in advance. Cloud providers will even turn down certain reservations because they don't have enough CPUs or the right type of CPUs.

Thinking in Systems, Shipping in Loops

(3 minute read)AI has removed the typing from software engineering but left the system design. What's left is designing the loop that decides whether the output is right. Great system design is defined by resilience, self-organization, and hierarchy. Resilience is AI checking its own work, self-organization is the loop learning, and hierarchy is the layering of skills, tools, and sandboxes into composable components that are reused once verified to work.
