Announcing GA of VI Java API 5.1 Supporting vSphere 5.1

It’s been two months since I announced beta of VI Java API 5.1 supporting vSphere 5.1 on September 23. I got many emails asking for the GA date from ISVs and IHVs as the API is now a corner stone in their products. With the long (could be longer, BTW) Thanksgiving holidays, I got some time to review the fixes and release the GA version. I intended to announce it yesterday but somehow extra spam comments pushed the database behind over 100MB limit thus I could not post any new article.

OpenStack: 7 Core Projects You Should Know

Last week I took a two day boot camp on OpenStack, which is increasingly popular these days. The project was initially created at Rackspace in answering Amazon Web Services, and open sourced to the community.

Must-Have Tool: ZoomIt for Technical Presenters

In one of my previous posts, I introduced the Remote Desktop Connection Manager. Here is yet another must-have tool: ZoomIt. If you frequently present technical contents on Windows, you will find it very useful, especially when you want to show source code or screen details to your audience.

I’ve found many cases in which presenters had trouble to walk through source code because the font was too small for audience to see clearly. Instead of using this tool, they often tried to change IDE editor settings for a larger font, which worked but not nearly convenient.

Encrypt and Decrypt Password in C#?

I just spent a little time playing with C# on password encryption. Here is a sample code I wrote to get myself familiar with related APIs. Overall it’s pretty straight forward – it first encrypts a clear text to an encrypted Base64 encoded string, then reverses it.

Must-Have Tool: Remote Desktop Connection Manager

I think most of us have used Microsoft Remote Desktop Connection (mstsc.exe), which is used to connect to a remote server using RDP protocol. If you have more than several remote servers to connect, it can be very inconvenient to navigator through them. Microsoft knew that and created a new tool called Remote Desktop Connection Manager. You can download it for free at Microsoft site here.

Conceptual Deep Dive in VMware vCenter Single Sign On

One of the key new features in vSphere 5.1 is the Single Sign On. Because it’s new and also complicated, I’ve heard it’s not easy to get it right the first time. Experts recommend that you should play with it in a test or staging environment before upgrading your production environment.
