Sass, Heroku, and you.

I like Sass and I like Heroku, but they don’t necessarily like each other. Because of Heroku’s read-only file system and Sass’s tendency to write files to disk, a workaround is needed to get the two to play nicely together. Heroku’s own blog suggests a solution where Sass writes its generated css files to the Rails […]

When you are planning hardware resources for a web presence that needs to be available, you tend to assume the worst case scenario, the maximum connections that need to be supported – and then some to make sure you don’t go down when there is one or 1000 more connections. Cloud hosting changes the view and strategy of capacity planning. In fact, we are now talking about reverse capacity planning. Forrester Analyst James Staten highlights a stealth startup that is subscribing to an IaaS cloud and “most of the time pays next to nothing to do this”.

Gartner: SaaS Matures, Merges Into The Cloud

What is exactly the difference between software-as-a-service (SaaS) and a cloud application? If you aren’t confronted with both topics frequently, this question is likely to be confusing and you may be tempted to simply answer that there is no difference. In fact, the difference is subtle and is based on the fact that SaaS is a subsystem of cloud computing that represents the application layer of the cloud. Down the road, this differentiation may not matter anymore as SaaS has matured over the past few years and SaaS services could be considered as cloud services in the not too distant future, at least if we believe Gartner’s projections.

You just know that a trend is significant when the government is jumping on the train, even if we have to say that we are seeing much more apparent consumer technology focus in the U.S. government than ever before. However, we think it is noteworthy to say that the U.S. government now has its own app store. So far, there are 18 applications available, but a list of government apps shows that there are 109 different apps that are already available or are currently developed for public and non-public use.
