Cockpit is a service for Linux that provides a web-based interface for managing and monitoring hosts. It can be deployed in any size organization, even a small office, and it’s a great way for home users to maintain the family IT infrastructure. I use it to manage and monitor all of the computers in my house—including Raspberry Pi. Cockpit is a free and open source software project released under the LGPL v2.1+. It is sponsored by Red Hat and included in Red Hat Enterprise Linux as the RHEL Web Console.

One of the most important features of rsync is the method it uses to synchronize preexisting files that have changed in the source directory. Rather than copying the entire file from the source, it uses checksums to compare blocks of the source and target files. If all of the blocks in the two files are the same, no data is transferred. If the data differs, only the block that has changed on the source is transferred to the target. This saves an immense amount of time and network bandwidth for remote sync.
Rsync is pretty handy. You can even get it to work on Windows if you want.
This is a super quick post on a simple method to exfiltrate data from systems running BusyBox, a shell commonly used on embedded devices. Such systems often lack common tools, presenting a challenge when you need to move data about.
This can really come in handy when working with phones or embedded devices. BusyBox is pretty widely used, but you’ll need a net connection obviously.
This may sound a bit like an older technology called virtualization, but tools like DC/OS and Kubernetes takes things much further. For one, they can run massive quantities of software far more efficiently than virtualization ever could. “The magic of the container world is that the computational overhead is far less than full virtualization,” says Mike Stoppelman, the senior vice president of engineering at Yelp, which now runs its operation at DC/OS. “Even today, moving around a 20 megabyte container is so much easier than moving a 100 megabyte virtual image … and the network traffic created by this stuff is an order of magnitude less.”

Good article that covers the basics of the new containerized world and serves as an introduction to the concept of “Google infrastructure for everyone else” #GIFEE. I think this is the future.
