OpenDNS is a popular DNS provider used widely both in the server as in home desktop, one of the feature they provide to their customer is DNSCrypt, a security enhancement that should add protection against all DNS based attacks, such as cache poisoning.

In the same way the SSL turns HTTP web traffic into HTTPS encrypted Web traffic, DNSCrypt turns regular DNS traffic into encrypted DNS traffic that is secure from eavesdropping and man-in-the-middle attacks. It doesn’t require any changes to domain names or how they work, it simply provides a method for securely encrypting communication between OpenDNS customers and their DNS servers. The software is released as open source on GitHub.

At the moment this solution only works in conjunction with OpenDNS, which means that you need to change your computer’s DNS provider to OpenDNS to make use of the this security feature, that’s their business after all.

Let’s see in detail how to use it on Linux. Continue reading »

Sometimes is useful to sync automatically files over the net between 2 or more computers, maybe you want to keep some configuration files aligned on different servers or maybe you have a cluster of web servers and you want to keep their document root aligned so your customer will always see the same result.

You could do this with a network filesystem like NFS, GlusterFS or Coda File system.
But why do complicated things when you could easily do this just keeping in sync the local filesystem ?

In a former article I’ve talked about Unison to do a work like that, and it works, the limit of Unison is that you can have just 2 nodes, but if you have more nodes you have to use a different solution like the one i present you today: csync2

As the open source community continues to grow and thrive through the popularity of such enterprise ready platforms as Red Hat, the number of open source medical applications also grows with it. The truth is, medical software is expensive. Most health care providers – doctors, hospitals, dentists, independent clinics – have been under a lot of pressure to maintain or reduce run costs while at the same time continuing to provide the quality patient care and customer service expected of the medical care industry. In an effort to control these costs, many health care organizations are looking toward open source software to help them manage their complex billing and electronic medical records. This is an especially hot topic with the United States government mandating that health care providers move from a paper based system to a primary electronic medical record system over the next two years, complete with short term financial incentives in the form of government refunds for early compliance and hefty fines for late adopters.

With that said, here is a list of some of the top open source billing and EMR software available right now.
