Jonathan Willis, software developer by day and superhero by night, asked an interesting question via Twitter on StackOverflow:
tl;dr Many Rails apps or one Vertx/Play! app?
I've been having discussions with other members of my team on the pros and cons of using an async app server such as the Play! Framework (built on Netty) versus spinning up multiple instances of a Rails app server. I know that Netty is asynchronous/non-blocking, meaning during a database query, network request, or something similar an async call will allow the event loop thread to switch from the blocked request to another request ready to be processed/served. This will keep the CPUs busy instead of blocking and waiting.I'm arguing in favor or using something such as the Play! Framework or Vertx.io, something that is non-blocking... Scalable. My team members, on the other hand, are saying that you can get the same benefit by using multiple instances of a Rails app, which out of the box only comes with one thread and doesn't have true concurrency as do apps on the JVM. They are saying just use enough app instances to match the performance of one Play! application (or however many Play! apps Continue reading
A popular new use case for SDN rests in the software-defined data center (SDDC). With F5 and VMware, the provisioning, automation, and agility customers demand for their SDDCs is at their fingertips.
This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.
In late 2007, AOL security researcher William Salusky and his team discovered one of the first reported instances of malvertising -- a digital ad running on aol.com had been configured to serve up malware to unsuspecting visitors. This turned out to be the beginning of a new era where attackers use a company’s digital footprint (web infrastructures and mobile apps) to distribute malware and commit fraud.
For security teams, protecting the digital footprint, which resides outside the firewall, poses three distinct challenges. Namely, securing assets you know about, securing assets you don’t know about (like those created by someone within the organization or by an authorized third-party), and identifying rogue assets that are impersonating the organization’s brand or sub-brands.

Sipping from the firehose is a big problem in the tech industries. Every time I turn around there’s yet another new technology to make everything better. If you can’t quote rule 11, you need to learn it by heart. Now. I’ll wait right here while you do the memorization thing.
So — why the hype cycle? Essentially, it comes down to this: we’re emotionally driven creatures. Advertisers have known this for years; to wit —
Mark the last words in that quote: it’s about selling an experience, rather than a Continue reading

Ansible is a very flexible and extensible automation tool, and it can be used in a lot of different environments that may not fit your preconceived notions of Ansible as an SSH-based tool to configure Linux and Unix systems. Here are a few other things you can do with Ansible, and a few ways to further customize and configure how your automation works. I hope these tips are useful! If you have any of your own to share, feel free to send us a tweet @ansible!
Most Ansible playbooks are used to configure and manage servers. Web servers, database servers, and so on. But anything with an SSH interface or an API can be managed with Ansible, too. For example we have modules to talk to cloud platforms, Citrix NetScaler and F5 load balancers, and other networking equipment. These modules are really helpful for tasks like multi-server rolling upgrades or other complicated orchestration tasks that need coordination with your broader networking environment.
You can also implement custom connection plugins for those really weird or legacy devices. There are a number of lesser-known ones shipped with Ansible, including Continue reading
