Ubuntu home server headless – Boot non-interactively
Running a server completely headless is fine as long as the server boots and remote access is available (via ssh, rdp, vnc or similar). I have a HP mediasmart EX490 server which has no VGA output (though it is possible to get a VGA/PS2 connection with a debug cable). These are some tips for running the EX490 completely headless with Ubuntu.

HP EX490 MediaSmart server: Using a 6TB GPT boot drive in Ubuntu with a non EFI BIOS!
HP EX490/EX495 MediaSmart servers were at one time very popular option for a home server. These 4-bay home servers came with Microsoft Windows Home Server V1 as the operating system. It was a very small (even smaller than the newer Gen8 ProLiant Microserver) yet feature rich home server. I bought mine in 2011. This post is about some history of the upgrade path of my EX490 and a recent update to a 6TB GPT boot disk.

Using Eigen Linear Algebra Library with Visual C++ 2010 Express 64bit
Eigen is a free and open source, relatively fast, very versatile linear algebra library written completely in C++ templates. It is very fast and in some cases produces code as fast as commercial implementations like Intel MKL, AMD ACML etc. The beauty of the Eigen is, it’s completely written in C++ templates and it’s very easy to plug it in to a project compiled with any supported compiler.
Here I describe the process of how to install Eigen with Microsoft Visual Studio 2010 Express and 64bit compilers from Microsoft Windows SDK 7.1 supporting OpenMP and vectorization with SSE2. All these tools are free.

Securing Ubuntu Server with a free SSL certificate from StartSSL™
Pre-Requirements:
Working LAMP installation with Ubuntu Server. Help is here and here. SSL security is enabled for Apache with Name Based Virtualhosts.
Assumption
Name of the website is www.example.com. Replace it with your correct domain name.
Obtaining a SSL certificate for your website from StartSSL is quite straightforward. Use ExpressLane option from the StartSSL start page and steps will be self explanatory. Here I assume you already created a personal digital certificate, logged in to StartSSL, verified your domain, and created a private key (you can also create your own private key and a CSR yourself from openssl command) and finally downloaded/saved both your server certificate and private certificate files.
