During the last month, I’ve watched faculty and staff moving great quantities of furniture between classrooms and offices. It’s a summer ritual at HPU.

We work and live on an island, so shipping pre-assembled furniture to our campus can be expensive.

There are several sites with interesting collections of economical yet attractive flat pack furniture. These designs are much easier to ship to Hawaii in bulk than comparable pre-assembled furniture.

Here’s two YouTube videos with some interesting ideas in flat pack furniture.

• More Creative Furniture for Cramped Urban Living: 20 Pieces of Ingenious ‘Flat Pack’ Furniture

Here’s are 2 cardboard classroom desks that were designed by students at the Rhode Island School of Design. The specific dimensions of this cardboard chair, complete with a functional desk, are available at the YouTube page for the first video called Amazing Cardboard Chair Design Unfolding RISD.

This next video shows the assembly process for a Legare desk, available from SimonHelene.com. The components are manufactured at the company’s factory in New York state, and can easily be shipped in a flat pack. Putting the desk together is much easier than the flat pack kits sold at many big box stores.

I’m back in Honolulu after my conference, and I am catching up with my social media sites today. Some of the sites have reasonable mobile versions, so I was able to post updates and stay current through my phone or my iPod’s WiFi connection:

• Facebook
• Plurk
• FriendFeed
• Twitter

At least one of my sites offer mobile versions with very limited feature sets:

• LinkedIn offers a contact list. On an iPod Touch, it’s a little clumsy to use. Other than that, there’s hardly any useful content available. 

I do like using OpenDNS.

Protection from phishing sites, the ability to whitelist or blacklist specific URLs, community tagged categories… and it’s free.

It only takes a few minutes to change your computer’s domain name settings to the OpenDNS servers, as long as you have administrative rights on your computer. Just read the OpenDNS tutorial and make the appropriate choices. Be sure to reboot or restart your computer after confirming the changes.

Your Internet connection might become faster, too.

Long-time readers of billso.com may remember that I used reCAPTCHA to validate comments about my articles. reCAPCTHA is a web service that shows users pictures of two words. The service knows one of the words. The second word was provided by an electronic book scanning project that needs help with its quality control.  reCAPTCHA send the results back to the scanning project, to help them fix their documents.

A CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) system is a simple test that determines if a computer user is a machine or a human. CAPTCHAs are small puzzles that people can solve quickly, while being too expensive for a computer system to solve.

I dropped the reCAPTCHA feature in May 2008, because the system was not stopping comment spam from appearing on my blog. “Comment spam” is just messages that have little or no relevance to an article or page.

In the past, people who wanted to crack a CAPTCHA system might pay users to stay at home and decipher dozens of captchas, in return for free content or Internet access. But people are slower and less reliable than computers. Processing power continues to improve, while CPU costs get lower.

Paying the price

Stephan Chenette, the manager of security research at Websense Security Labs, notes that CAPTCHA technology had made incremental improvements since 2000, while CAPTCHA crackers bought faster hardware and invested more in their efforts:

“CAPTCHA has been broken for the last year and a half. The technology has really not progressed. They’ve got a little bit harder but the hackers have made programs that can easily break them. This works both with print and audio CAPTCHA. All of these have been broken in one way or the other.”

In the last few months, the CAPTCHA systems of several major web sites have been cracked by automated systems:

• January 2008: Yahoo Mail
• April 2008: Gmail and Hotmail
• May 2008: Craigslist

This has resulted in a flood of spam, scams, and fake postings on services around the world. It’s become quite easy to create a fake Web site that can fool many users. Social networks like MySpace and Facebook offer many more opportunities to trick users into revealing their credentials and personal information.

In the last few years, financial service companies and banks have adopted multifactor authentication systems that ask users for more than a password or a CAPTCHA solution. Now organizations in other industries are looking at similar solutions, because it has become much less expensive for scammers and crackers to break these companies’ systems. Several OpenID providers have added multifactor features to their authentication systems, too.

The retirement of Bill Gates from daily duty at Microsoft prompted bloggers and journalists to write long articles about Microsoft technology. It’s summer, and we have to fill the pages somehow. 

This Engadget article called Bill Gates: top ten greatest hits (and misses) has some details and product photos. Two of the “misses” are interesting.

The AutoPC was a voice controlled system that connected the driver to music, GPS and Outlook services. It went on sale in 2000 and died a quick death, but many auto manufacturers are offering systems with similar features in 2008. The same Microsoft business unit that developed the AutoPC also developed the SYNC system for Ford. 

The second “miss” is another example of pervasive or ubiquitous computing. It’s interesting that both of these products were championed by Bill Gates himself. 

I have worn my Suunto N6 HR SPOT watch almost every day for the last 2.5 years. Yes, the watch is a little large, and I have to clip it to a USB charger every 2 or 3 days to freshen up the battery. I never got the heart rate monitor feature to work properly, though. 

Microsoft partnered with Clear Channel to distribute news, sports, stock market and other data to users via Clear Channel FM radio stations.The silvery rim of the watch face is the FM antenna. It’s a one-way device that receives broadcasts, so it’s impossible to send information from the watch.

I don’t use Outlook, so I never use the appointment and messaging features. But the baseball scores are usually up to date, as long as I’m in a Clear Channel city, and I never need to set the time. It’s synced by an atomic clock somewhere in the cloud. 

Sadly, Microsoft discontinued the SPOT watch line in April 2008 - see this Engadget article called SPOT watches R.I.P. - 2004-2008. The cloud service still works on MSN Direct. I just go to the web site, log in, and select the information and faces for my watch. 

I see fewer wristwatches on wrists these days. Many of my friends rely on their mobile phone’s clock instead, as they carry their phones with them everywhere. Most modern mobile phones sync their clock to their carrier’s system.
