The Best and the Worst Tech of the Decade

By James Turner
December 17, 2009

With only a few weeks left until we close out the 'naughts and move into the teens, it's almost obligatory to take a look back at the best and not-so-best of the last decade. With that in mind, I polled the O'Reilly editors, authors, Friends, and a number of industry movers and shakers to gather nominations. I then tossed them in the trash and made up my own compiled them together and looked for trends and common threads. So here then, in no particular order, are the best and the worst that the decade had to offer.

28 Rich Data Visualization Tools

By Theresa Neil
December 10, 2009

We're currently working with a dozen different clients, all web application (re)designs. All of these clients have data rich applications and need equally rich data visualizations to help their end customers analyze data quickly and effectively. What makes my job really interesting is that these clients are in different industries and are using different technologies. So we have pulled together a set of 25 tools for creating graphs, Gantt charts, diagrammers, calendars/schedulers, gauges, mapping, pivot tables, OLAP cubes, and sparklines, in Flash, Flex, Ajax or Silverlight.

By John Barlow

50 Most Usable RIAs

By Theresa Neil
September 2, 2009

We applied two simple criteria to identify the 50 most usable RIAs: Number 1: Does it adhere to the 10 basic usability principles? Number 2: Is it really rich?

A usable RIA will embody these six principles: Make it Direct, Keep it Lightweight, Stay in the Page, Provide an Invitation, Use Transitions, React Immediately.

By Kyle Dent
July 22, 2009

Seeking Ubiquity

By Kurt Cagle
September 9, 2008

The command line is perhaps the most fundamental of all user interfaces - at a terminal, a prompt character appears that you can type in a command with zero or more arguments, then press the Return key to evaluate that command. As an interface it has some serious limitations - there are typically few indications about what specifically can be typed into that interface, or the action that will ensue once you do enter the line, but for programmers in particular, the command line is also the foundation on which every other user interface ultimately rests.
