03.Red 04.Hat Introduces New Linux OS for Containers

The world’s largest open source software provider just brought a new operating system on the market. On Thursday, Red Hat, known for its enterprise distributions of the Linux operating system, launched its Enterprise Linux 7 Atomic Host OS. The new OS is specifically designed to run the latest generation of applications as Linux containers.
Linux containers are virtualization environments that allow organizations to run multiple isolated Linux systems on a single Linux control host. Containers introduce autonomy for applications by packaging apps with the libraries and other binaries on which they depend.
Container-based architectures can provide more development and deployment flexibility, while simplifying maintenance requirements and maintaining the same level of performance, stability andsecurity  as non-virtualized systems.
Enterprise-Grade Linux Containers





The new operating system will provide enterprises with the tools they need to build and run their own Linux containers, according to Red Hat. In addition, the company said its latest OS is built specifically with the needs of enterprise IT departments in mind, with enterprise-grade security, ongoing product upgrades, proactive diagnostics, and access to support.
“Red Hat is committed to offering enterprises a complete and integrated container-based infrastructure solution, combining container-based application packaging with robust, optimized infrastructure that will enable easy movement of Red Hat Enterprise Linux-certified applications across bare metal systems, virtual machines and private and public clouds -- all of this with the product and security lifecycle that enterprise customers require,” Red Hat said.

Controlling data flow using sluice

Earlier this year I was instrumenting wifi power consumption and needed a way to produce and also consume data at a specific rate to pipe over netcat for my measurements.  I had some older crufty code around to do this but it needed some polishing up so I eventually got around to turning this into a more usable tool called "sluice".  (A sluice gate controls flow of water,  the sluice tool controls rate of data though a pipe).

The sluice package is currently available in PPA:colin-king/white and is built for Ubuntu Trusty, Utopic and Vivid, but there the git repository and tarballs are available too if one wants to build this from source.
