Price per Unit (piece): $399.99

The highly extensible Open Computer is a configuration of PC hardware capable of running unmodified OS X Leopard kernels. If you purchase Leopard with your Open Computer we will not only include the actual Leopard retail package with genuine installation disc, but we also preinstall Leopard for free so you can begin to use your computer right out of the box. If you choose to have Ubuntu preinstalled we will not include installation media for Ubuntu but the media can be downloaded from Ubuntu.com. If you buy a Microsoft operating system, your Open Computer will have the OS preinstalled and the OEM OS package will be included with your system.

With 4GB of RAM... a really nice OS X dev box.

Introduction

The way Facebook integrates with external applications can be compared to how a proxy gate can serve pages produced by external servers. It passes the web browser request to the application server and then the page produced back to the web browser. It works just like that but:

* the external page is not served as it is to the client - but rather is a partially transformed and then inserted into the Facebook layout
* all requests from the browser are passed ad POST requests to the app server - this is because Facebook always adds additional parameters (like the facebook id of the user) to the request

This means that the page produced by the application can contain additional Facebook XML tags that are interpreted by Facebook and transformed for bigger HTML chunks, and also cannot contain some HTML tags, but the parameters, relative links work just as if the user was accessing the application server directly.

When producing the page the application server can use it's own databases and additionally it can contact Facebook using the REST api to get additional info.

Richard arrived in Boston the day after the company was incorporated. We had been busy raising the money, finding a place to rent, issuing stock, etc. We set up in an old mansion just outside of the city, and when Richard showed up we were still recovering from the shock of having the first few million dollars in the bank. No one had thought about anything technical for several months. We were arguing about what the name of the company should be when Richard walked in, saluted, and said, "Richard Feynman reporting for duty. OK, boss, what's my assignment?" The assembled group of not-quite-graduated MIT students was astounded.

After a hurried private discussion ("I don't know, you hired him..."), we informed Richard that his assignment would be to advise on the application of parallel processing to scientific problems.

"That sounds like a bunch of baloney," he said. "Give me something real to do."

So we sent him out to buy some office supplies. While he was gone, we decided that the part of the machine that we were most worried about was the router that delivered messages from one processor to another. We were not sure that our design was going to work. When Richard returned from buying pencils, we gave him the assignment of analyzing the router.

jQuery is a new type of JavaScript library.

jQuery is a fast, concise, JavaScript Library that simplifies how you traverse HTML documents, handle events, perform animations, and add Ajax interactions to your web pages. jQuery is designed to change the way that you write JavaScript.

I gave up JS frameworks a long time ago, but maybe this one is decent and not too bloated.

Tracking UI Level Links: An Open Source Script

One of the challenges with the current complex site designs is that multiple links to the same destination tend to appear on the same page.

This does not allow you to understand how your allocation of real estate is being used without resorting to really fancy analytics packages.

To solve this problem I developed a script that upon every click, walks up the document object model (DOM) looking for a an attribute on an HTML tag of ui.

If it finds one before it hits the BODY tag, then it adds a parameter to the link called ui with the value of that attribute, allowing you to understand which links on a page are being used. Shown below is a report from Google Analytics for this site showing how people arrive at my bio page:

So there’s no point in zebra striping?

This experiment yielded no evidence that zebra striping consistently improves the accuracy or speed of tasks. This would seem to suggest that we shouldn’t bother with zebra striping anymore.

However, there are a few arguments against tossing zebra striping out altogether.

Firstly, in this study there was a subjective preference for striped tables over plain. My reading and discussions with others suggest a number of people find zebra-striped tables more aesthetically pleasing. If many users like zebra striping (and another large group aren’t fussed either way), then why not apply it?

Secondly, this was just one experiment, with one dataset. It is possible that the particular design of this experiment meant that zebra striping had little effect. In other cases, particularly when there is considerable space between columns and/or the user is required to scroll horizontally, a more pronounced effect may have been observed.

Finally, and perhaps most interestingly, a number of participants in the study spontaneously reported using their finger, on or over the computer screen, to follow down columns and across rows. Other participants used their mouse to highlight rows of interest. These people were, in effect, creating their own “temporary” zebra striping. So we may be reducing the burden on our users if we do the zebra striping for them.
