An anonymous reader writes to mention an article at the IBM site from earlier this week, which purports to offer good Unix 'habits' to learn. The ten simple suggestions may be common sense to the seasoned admin, but users with less experience may find some helpful hints here. From the article: "Quote variables with caution - Always be careful with shell expansion and variable names. It is generally a good idea to enclose variable calls in double quotation marks, unless you have a good reason not to. Similarly, if you are directly following a variable name with alphanumeric text, be sure also to enclose the variable name in square brackets ([]) to distinguish it from the surrounding text. Otherwise, the shell interprets the trailing text as part of your variable name -- and most likely returns a null value."

Jonas Wisser writes "BBC is reporting that a newly created Pentagon unit has a mandate to fight 'inaccurate' news stories. From the article: 'The Pentagon has set up a new unit to focus on promoting its message across 24-hour rolling news outlets, and particularly on the internet. [...] A Pentagon memo seen by the Associated Press news agency said the new unit will "develop messages" for the 24-hour news cycle and aim to "correct the record". A spokesman said the unit would monitor media such as weblogs and would also employ "surrogates", or top politicians or lobbyists who could be interviewed on TV and radio shows.'"

With the announcement that Wired and other news organizations will now be reporting from Second Life, they've put up an article on the Wired property and have created a Guide to the larger Second Life world. From the guide: "Today, Second Life is second home to half a million people, and everyone from Duran Duran and Wells Fargo Bank to the Department of Homeland Security has funded real estate here. The national currency of Linden dollars is freely convertible to US dollars (and the exchange rate is quite favorable at the moment!), and an increasing number of residents are ditching their jobs back on Earth to make their living entirely within Second Life's economy. But this exotic realm can seem bewildering and strange to first-time visitors (affectionately known as "noobs" in the native parlance). Let Wired be your guide."

Gosalia wrote to let us know about an article which opens with: "In a legal win for Google, a federal judge dismissed a lawsuit filed by a writer who claimed the search giant infringed on his copyright by archiving a Usenet posting of his and providing excerpts from his Web site in search results." Thankfully, we can all still read Usenet articles on Google as well as other archive services.
