ARM. When used in a sentence it may refer to the company (ARM Holdings), one of its numerous CPU versions, or even a way of life. But we just call it ARM. ARM (the company) creates low power processor designs which they license to other companies to implement; Licensees enhance ARM’s design and manufacture the actual chips. The resulting processors are the defacto standard in the fiercely competitive consumer mobile space of tablets and cell phones. Of course, the thing that makes ARM interesting to Red Hat isn’t consumer mobile, it is evaluating their potential in servers. In theory if they perform well, their low-wattage designs might be quite compelling.

The test web service
The test web service implements a simple file cache storing up to 10 copies of any given named file. Uploading copies beyond the 10th one causes the oldest version to be discarded. The server supports a variety of requests allowing
- a new version of a file to be uploaded
- an existing file version to be downloaded
- listing of the name and version counts of all files in the cache
- deletion of all copies of a named file
- deletion of the whole cache

I found this interesting Node.js article from The New Stack. A handy piece for those of you considering Node and especially now that we now have it in both Software Collections and OpenShift.

Red Hat Developer Newsletter – July 2014
Welcome to the Red Hat® Developer Newsletter.
Can you believe the year is half-over already? Time flies when you’re having fun. 😉 We’re certainly having fun at Red Hat and hope you are, too. Last month Red Hat Enterprise Linux® 7 became generally available, and there’s definitely a lot of wonderful buzz about it that contributes to that fun.

Is Java really greedy for memory?
Java is often blamed for being an over-hungry consumer of physical memory. Indeed, until recently our OpenShift team were tempted to draw this same conclusion. OpenShift is Red Hat’s open source Platform as a Service (PaaS) product. You can access it via public Cloud infrastructure managed by Red Hat (OpenShift Online) or even deploy it to your own data centre/private cloud (OpenShift Enterprise). OpenShift Online provides simple and manageable scalability to anyone developing and deploying web services. One of the OpenShift team’s goals is to maximize the number of guest Java EE deployments on any underlying physical host. However, in the first release of OpenShift meeting this goal was challenged by the high physical memory use observed in many of the deployed JVMs. With only so much memory available on any given physical host the more memory each JVM uses the lower the density of guest deployments.

(Editor’s correction: Flock is a “new, larger and pre-scheduled conference” for North America and Europe) is just a few weeks away and will be hosted in Prague, Czech Republic.
The entire list of sessions can be seen here
, but below is the list of the 39 sessions delivered by Red Hatters. Have a great conference!

Red Hat is one of the EuroPython sponsors this year and it’s already less than 2 weeks away! I’m looking forward to meeting many Pythonistas and see the great city of Berlin for the first time.
The organizers have assembled an informative agenda for Pythonistas, both young and not-so-young. 😉 Be sure to attend these great Red Hat sessions:

Excerpts from the original article:
“Now that Red Hat Enterprise Linux 7 is generally available, we are re-casting the Red Hat Enterprise Linux High Touch Beta program into a series of Red Hat Enterprise Linux 7 special interest groups (SIGs), the first of which is focused on application containers. The Red Hat Enterprise Linux Atomic Host SIG encompasses technologies that are required to create, deploy, and manage application containers.

Excerpts from the original announcement:
“Red Hat and Google are both committed to open source and we were both early proponents of Docker as well as key contributors to the Docker project. We are now joining forces to drive a new open standard around orchestrating Docker containers at scale for the management of cloud application deployments.
