Viewport width can be obtained via CSS, e.g. by using a media query for every screen width:

    @media (min-width: 400px) {
      .thing {
        background-image: url(size-400.png);
      }
    }
    @media (min-width: 401px) {
      .thing {
        background-image: url(size-401.png);
      }
    }

You could combine this with pixel density for even more specificity.

There are two advantages to using www.* for a main web site.

1. As luaks points out, you can use a CNAME to alias just the webserver, without affecting MX configuration, etc.

2. You can have use alternate subdomains (like static.example.com or cdn.example.com) for handling static content and prevent cookies from being sent with those HTTP requests. This is a slight performance gain.

Yep, here's the amplifier:

http://spacecollege.org/isee3/isee-3-reboot-amplifier-instal...

It is an AR 700S1G4 with rated minimum output power of 700W, and will be used in S-band. Here's the datasheet:

http://www.arww-rfmicro.com/post/700S1G4.pdf

At these frequencies, the Arecibo dish has a gain of around 72dBi, putting the EIRP at about 7 gigawatts.

For scale, a typical wifi router has an EIRP of around 50 milliwatts, so this is about 140 billion times more powerful.

Just to toss out a few ideas: software defined radio, high-throughput DSP (like audio processing or machine vision), MITMing of fast protocols, packet inspection, CPU emulation.

You are correct, the 4GB SD card is mostly about having a quick start ready-to-roll image.

All of the enclosure design files will be published on the Wiki shortly, so you'll be able to make your own. The desktop/laptop versions ship with a spare bezel, as well, so you have one to modify. You could happily make your own case or pay a fabricator to do so, but the case in the campaign is injection molded, so you'd likely pay a lot more to do so.

The focus of this laptop is really on versatile and hardware-hacking-power, not on raw performance. There are a number of flagship features that you won't find in a typical laptop, and gobs of expandability.

For example, there's an onboard FPGA, for when you're at the coffee shop and you need to MITM a high-speed / low-latency protocol.

The schematics are full of attention to detail and fantastic surprises: http://www.kosagi.com/w/index.php?title=Novena_PVT_Design_So...

As you've pointed out, it seems like a big price jump to go from the bare board to the desktop and from the desktop to the laptop, but you're actually getting a lot of components there, including: very flexible battery charge controller (runs ChibiOS on an ARM7), speakers, speaker mounts, machined SSD mounting rails, and cabling. The screen is a gorgeous IPS panel.
