- Thinking of Skipping Vacation? Don’t! by Rebecca Zucker: many of us have had our summer vacation plans cancelled due to the pandemic. Whatever your thwarted plans entailed, you might be thinking of skipping a vacation altogether. And given that productivity has been hampered for many of us over the last few months, it’s easy to think, “I should keep working, so I can get more done,” or “What’s the point?”.

Docker Hub to rate-limit free users by Jean-Laurent De Morlhon: effective November 1, 2020, anonymous Docker Hub users will be limited to 100 pulls per 6 hours and authenticated users will get 200 pulls in the same time-span. Users on the free plan will also be exposed to a new image retention policy which purges images after 6 months of inactivity. “We are making this move to optimize operations and make the Docker Hub service even stronger for developers and development teams around the world”, Docker said. Approximately 4.5PB of images are expected to be purged when the new retention policy is enacted.

- 4 reasons to invest in entry-level cloud talent by Kevin Kelly: how does an industry suddenly create a large number of highly-qualified cloud professionals with 15-plus years of experience? It doesn’t. Instead, businesses need to rethink who they hire and how they train and retain them. Rather than chasing and competing for a limited number of highly-experienced professionals, employers should surround their most experienced employees with highly motivated, entry-level talent with strong foundational cloud skills.

So, we decided to find out the answer through benchmarks.
