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/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.
Recently I migrated my blogs from AWS EC2 micro instance to a DigitalOcean 512MB VPS. Migration was surprisingly easy. All I had to do was sync everything from EC2 instance to DigitalOcean VPS using rsync provided I use Ubuntu 12.04 LTS server on both locations. This is what I did step-by-step.
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.
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.

I had a Homeplug AV link between my router and and network enabled devices (Raspberry Pi running Raspbmc and a LG-DP1B Media player) in my bedroom. I used the Western Digital Livewire AV Network Kit, which conforms to the Homeplug AV standard. When I moved to a new apartment the performance of the Livewire AV link was degraded significantly. I used to have a consistent throughput around 40Mbps before (out of the maximum possible 200Mbps) in the previous apartment. But with a very old power-circuit in the current apartment and also due to the fact, the living-room, where the router is installed, and the bedroom are connected to two different power-circuits, the sustained throughput obtainable was only around 15Mbps. (Which is actually lower than a good quality 802.11g link)
