HOW-TOs

I've recently written about using bash arrays and bash regular expressions, so here's a more useful example of using them to test IP addresses for validity.

One of the things I both love and hate about my job is getting assigned new projects. They can be about anything and everything. A few months back I was given an assignment to create some chroot jails for a group of customers so that they could securely upload files with sftp. The requirement was that the customers needed to be able to upload file, but in a secure and private way.

Bash Arrays

June 19th, 2008 by Mitch Frazier in

If you're used to a "standard" *NIX shell you may not be familiar with bash's array feature. Although not as powerful as similar constructs in the P languages (Perl, Python, and PHP) and others, they are often quite useful.

Product Review

Stubbornly, OpenOffice.org continues to ship with only a handful of templates. Despite the efforts of several sub-projects and individuals to change the situation, the standard OpenOffice.org download includes only a couple of slide show presentations and a few templates to accompany the wizards available in the file menu. This lack of templates is a serious handicap for many users, and often leaves a poor impression on new users who are accustomed to the selection of templates found in other office suites.

It's time to get ornery again with the FCC. Fortunately, they're asking for it, by soliciting comment on this FCC rulemaking proposal for "Service Rules for Advanced Wireless Services in the 1915-1920 MHz, 1995-2000 MHz, 2020-2025 MHz and 2175-2180 MHz Bands.

It's a chocolate-covered spider.

The depth of Microsoft loathing among our clan is perhaps only second to our penguin loving. This loathing makes sense, given that Linux and open-source people are so fiercely merit driven, and great products have failed to end Microsoft's hegemony. But times they are a changin', for a post-Gates, post-Microsoft age has already begun.

Does a system with dual Quad Core processors, 128GB of RAM, and a Tera-Byte RAID array seem pretty tame to you? Does writing a program with a dozen threads seem about as complex as an abacus to you? Does a database with a million records seem like something you'd put on a USB memory stick? Do you know who John Backus was? Are you cleared for ridiculous by the US Government?

If you don't get the title, you're probably too young to get the rest of this. If you don't know who John Backus was or what his contribution to computer science was then you're also, probably, too young.

Three things are striking about the recent launch of Firefox 3. First, the unanimity about the quality of the code: practically everyone thinks it's better in practically every respect. Secondly, the way in which the mainstream media covered its launch: it was treated as a normal, important tech story – gone are the days of supercilious anecdotes about those wacky, sandal-wearing free software anoraks. And finally – and perhaps most importantly - the scale and intensity of participation by the millions of people who have downloaded the software in the last week.

But the question has to be: what now? How can we harness that amazing spirit, to make the Firefox Effect permanent, not just a media event that comes around once every few years?

Nokia N800 for Geeks

June 24th, 2008 by Phil Hughes

Yeah, I know, the N810 is the "modern" system and, well, the N800 is too "consumer" for us geeks. Well, hype aside, I am seriously impressed with the N800. Here's why.

Computer virtualization is all the rage these days. Heck, in the video I shot last week, I installed about 12 Linux distributions on a VM, because it made recording a lot simpler.

We Linux folk are the reliable early adopters of innovative applications like Skype who have done a disproportionate amount of work to make it popular. The gift horse we've gotten in return is a usable but much less feature-rich version that is years behind the other platforms.

Heard of the Web? If not, read on. This month we talk with Matt Mullenweg about WordPress. If you want to get your hands dirty in Web code, take a look at the rest of our feature articles on WebKit, Dojo and OpenLaszlo.

In the rest of the issue, you'll find articles on OpenID, RDFa and Quanta Plus. Kyle Rankin puts a new spin (as in "no" spin SSD) on hard drives and also tells you how to migrate to that new disk (spinning or not). Mick Bauer continues his series on customizing live CD's. And, James Gray gives us a feel for the state of Linux in the enterprise. After all that, you may need some TV time. If so, check out our review on how to make that digital TV tuner card work in your Linux box.
