The CFEngine engineering team has recently discovered two security issues in the CFEngine Enterprise product: While the latter one (CVE-2021-36756) only affects CFEngine Enterprise deployments using the Federated Reporting functionality, the former one (CVE-2021-38379) affects all deployments running all supported versions of CFEngine Enterprise (and many unsupported versions, 3.5 or newer, to be more precise).

When the Daylight saving time starts, and the computer’s clock jumps forward, what does cron do? If the clock jumps from 1AM to 2AM, and there is a job scheduled for 1:30AM, will cron run this job?

It used to be simple to improve the performance of a website. However, the introduction of client-side JavaScript has opened up a whole new world of ways for websites to be painfully slow. Measuring this increased slowness will require the development of new measurements. They're known as the Core Web Vitals by Google.
