It's time once again for the Developer Shed newsletter! Spring is in full swing here. In a place like Florida, this means the mornings and evenings are less cool than they were a month or two ago, the garage sales have picked up, and (luckily) we're starting to get enough rain for any grass that went dormant to come back to life. Where you live, though, it could mean anything from giving your web site a face lift to major new programming projects. If you're heavily involved in the latter, you'll want to check out the item we're highlighting for you this week from eWeek. This slide show reveals 10 important truths about project planning. Remember, forewarned is forearmed.

On Dev Shed, we've been running several very interesting series lately. Whether you're trying to clean up your JavaScript with event delegation, learn some new ways to use the versatile Code Igniter PHP framework, assign contract numbers or even build a navigation system, you won't want to miss this week's selection of articles. ASP Free, meanwhile, offered a good mix of articles on Windows security, Silverlight, and databases.

Of course we published our major web site building articles on Dev Articles. Stop by there this week and you'll learn how to build a web page calendar, a common browser menu, a better FAQ page, and more. Or if hardware is more your thing, you should pay a visit to Dev Hardware, where you'll find reviews galore. This week alone you can read about a multi-room audio system, a digital camera, a wireless all-in-one printer...and the list goes on. Did I mention that both Dev Articles and Dev Hardware publish new items five days a week?

We'd never forget those of you trying hard to climb to the top of the search engine results pages. SEO Chat explained how to make sure your web site is inviting to both search engine spiders and human visitors, touched on the topic of one-way links, and delved into duplicate content issues on e-commerce web sites. If you're new to having your own web site, you'll want to check out Dev Mechanic. This week, we talked about the challenges you may face if your web site doesn't boast a lot of text, and alternatives to using the standard CAPTCHA for verification. (Be sure to come back on Friday, when we'll talk about some great ways to monetize your web site!).

That's not all. Codewalkers ran a book review that systems administrators may want to read; the book in question covers Nagios, a powerful open source network and server monitoring application. Finally, if you're looking for a good web host, but don't know where to turn for a trustworthy review, check out Web Hosters; you'll learn about Clickfire, a site that goes above and beyond when it comes to reviewing web hosts.

As always, thanks for reading. Until next week,
Developer Shed Staff

Is Windows Security Actually Secure?
by Joe Eitel, 2009-04-27


The Internet has always seemed like the Wild West, which is both good and bad. Anybody could take advantage of it, from bloggers wanting a soapbox to malicious hackers setting up spam networks. After all this time, one would think that the number of Trojans, phishing attacks, and other malware we have to deal would have gone down, especially since Microsoft has been touting improvements to their security. As a recent report from Symantec shows, however, things have been getting worse rather than better.

The Trouble with CAPTCHA
by Bruce Coker, 2009-04-29


The technology world is full of terrible acronyms, but if there were a competition to identify the worst, CAPTCHA - Completely Automated Public Turing test to tell Computers and Humans Apart - would have to be a major contender. Nonetheless, anyone who has ever registered with a social networking web site or forum knows what a CAPTCHA graphic looks like. They are those strange, squiggly collections of letters that users are asked to type to confirm that they are in fact people rather than machines, based on the supposition that computers are unable to read the oddly shaped and colored characters. Having offered good protection for years, these are now under attack. Keep reading for today's alternatives to CAPTCHA.

Scientists Create the Blob

It sounds like a monster straight out of a Hollywood horror movie and, inevitably, it was made in Tokyo. But scientists at the applied physics lab at Waseda University see many peaceful, scientific uses for their self-propelled chemical gel, including those for which engineers would normally use electronics.

Shingo Maeda and his colleagues composed the gel from polymers that change in size depending on their chemical environment. The right environment makes the gel oscillate, which in turns causes it to wiggle along a surface rather like an inchworm, without any electricity coming into play. When engineers try to build devices that can move mechanically, it usually involves complex fabricated circuits or external control devices, Maeda notes. A chemical system, such as this gel, may be able to generate its own control signals from within.

Strangely enough, the oscillating reaction that makes the gel move has also been used to perform calculations, with the substances involved acting like a chemical brain. The scientists hope to improve the substance's ability to move independently (though it will still only be able to do so on a lab bench, since it requires specific chemical conditions). Eventually, Maeda believes the gel may be used to make some of the components for a future robot. There is no word as to whether the scientists have accepted any funding from Time Warner for their project.

Saving Geocities for Posterity

Those who have been on the web long enough remember Geocities, Yahoo's old web hosting service. A collection of personal web sites that existed before the term blog, Geocities offered an early outlet for online creative expression to perhaps millions of users. Yahoo's announcement that they will be shutting down the community later this year (perhaps in response to many moving on to other places on the web) means all of that data will be lost...or will it?

A group calling themselves the Archive Team hopes to limit the damage. They can't prevent Yahoo from closing Geocities, but they can preserve it. Team leader Jason Scott reported on his blog that his group has been downloading files at an enormous rate, and believe they've saved more than 200,000 web sites so far. Unfortunately, much of this raw, young Internet is already lost, since it appears that Yahoo quietly purged a number of neighborhoods before the project started.

Still, the team thinks they've saved nearly every remaining web site on Geocities from 1999 and before. The first step, according to Scott, is to archive the data. While his team doesn't plan to release the data, they do hope to make sure people can get it, somehow. Possibilities include putting the Geocities archive online as a sort of curated collection.

Bring on the Mind Control Lasers

What if you could treat diseases such as Parkinson's, epilepsy, schizophrenia and others with targeted viruses and blue lasers? That's the vision guiding researchers at the MIT Media Lab, who recently succeeded in activating a specific set of neurons in a monkey's brain. While such techniques have already been used in fish, flies, and rodents, this was the first time the technology has been used on a primate brain.

Researchers, led by neuroscientist Ed Boyden, created viruses that infect neurons with a type of channel that is sensitive to blue light. A blue laser shining on those neurons makes the channel snap open. Ions enter the cell, and the neuron fires. The engineered virus is injected into a specific, very small portion of the brain, and only one class of neurons actually turns the channel on. The blue laser targets a very specific part of the brain. This specificity minimizes potential side effects.

Compare that to current treatments for Parkinson's, epilepsy, and certain other diseases of the brain and psychiatric disorders. They often involve medicines with a broader reach and a wide range of side effects. Boyden's team, in contrast, showed that their technology worked on their subjects multiple times over the course of eight or nine months without causing damage to the neurons or activating the brain's immune system. The technique could offer an improved way to administer deep brain stimulation, which has shown promise in treating Parkinson's, epilepsy and depression, but also causes side effects.
