David Pogue explains DNS and why OpenDNS is a great service in this video.

OpenDNS is generally fast, has extra features like anti-phishing, shortcuts, and parental controls, and is run by non-evil people (perhaps unlike your ISP).

Other Options

But you should also check to see what DNS provider gives your particular location the fastest DNS response as we explained in the post Make your Internet faster by changing DNS.

We explained that you can use namebench to test a variety of DNS providers. I recommend running namebench multiple times since results will vary between tests. For me, Verizon’s DNS service actually provided the fastest and most consistent DNS speeds so I’m sticking with them for now for the quickest web browsing experience.

Profit Model

One way to see who is running the DNS on a particular network is to type in a long web address that doesn’t exist. Most DNS providers “hijack” the 404 Not Found response and give you something like the response below from Verizon. It’s annoying that this is a standard practice now, but your ISP and other DNS providers get extra income from search engines for directing people there.

Setup

Account setup is rather simple and done through a website.  You provide your address and phone numbers and that’s it.  You are limited to 10 phone numbers that can work through a MicroCell.  The good news is that it is locked down by phone numbers so your neighbor can’t use it.  Your address info is verified by GPS in the MicroCell during startup.  Unfortunately, this means the device needs to be near a window so it can get a GPS signal.  This is the oddest thing about it but apparently a requirement by the FCC.  If the GPS light does not come on, you need to move it closer to a window.  In some cases, you may need to try various windows at your house until you finally are able to get GPS.

Once you get GPS and are connected to your Internet, you can move the device as long as it doesn’t lose power.  This might be easy if are just relocating it in the same room.  If you are moving to an area with no windows, you’ll need a battery backup solution.  A cheap good option is the Tripp Lite Compact UPS.  Once you get GPS by a window, you can unhook the ethernet and move the MicroCell and UPS (uninterrupted power supply) wherever you like.  Of course, if you ever lose power for longer than your UPS can last, you’ll have to go through that whole process again to set it up.  This battery backup approach can make sense though because placement is very important.

Performance

AT&T claims a 40 ft range.  This is pretty decent and works out to an area of about 5,000 square feet, even more if you have 2 floors.  You’ll drop about 1 bar of coverage per major obstacle (like a wall) so to cover a whole house, you’ll want to put the MicroCell in the most central location.  Unfortunately, central often means no windows, hence the need for the UPS approach.

Even if you’ve got 5 bars and are sitting right next to the MicroCell, your call quality might be awful if your Internet isn’t good.  This is often the cause of any VoIP (voice over Internet protocol) issues and everyone’s assumption that their Internet is good.  To test the VoIP quality of your Internet, visit this VoIP test site.  If you don’t do well on those tests, you shouldn’t consider any VoIP products.

Assuming you’ve got good Internet and good bars, the MicroCell performance is very good.  You’ll know you’re connected because your phone will say something like AT&T M-Cell instead of just AT&T.  If you’re far from the MicroCell or have many walls between it and you, your performance may suffer so be sure to place it near where you expect to make most calls.  If you’re heavily using your Internet, streaming a video for example, your call quality may suffer if you don’t have your router setup properly.

Router Optimization

The MicroCell can go between your router and DSL/Cable modem but additional routers is rarely a good thing.  We recommend you hook the MicroCell up to your router so it can plug in anywhere on your network. We don’t recommend the use of a wireless bridge as wireless can be too sporadic for VoIP.  To optimize MicroCell performance, it should be given high priority in your router’s QoS (Quality of Service).  The MicroCell MAC address is on the bottom of the device.

Alternative

Before the MicroCell, the best alternative was the zBoost YX-510 Cell Phone Booster.  This is around $300 and requires that you have some signal near a window or in an attic.  Coaxial cable is run from an antenna to the zBoost repeating antenna.

Conclusion

If you’ve got poor Internet but some outside signal, the cell phone booster is your best bet.  If you’ve got good enough Internet, the MicroCell is a cheaper and superior option.  You may not like having to pay for such a device but it is a one time fee that should simply make your AT&T phones work at home.

I recently helped install a stereo system for a retail store in Virginia. They wanted to play background music for their customers but weren’t sure what they could play. In the US, it’s illegal to play the radio or regular CDs because those songs aren’t licensed to be played for “public performance.”

What happens if you play regular music CDs at your business? You might get a visit from the American Society of Composers, Authors and Publishers (ASCAP), Broadcast Music Incorporated (BMI), or the Society of European Stage Authors and Composers (SESAC). One retailer I know of was fined $7000 by ASCAP for playing music which was not properly licensed.

Legal Options

So how do you play music legally in the public? Here are some options.

1. Purchase business-licensed music CDs. Many retailers buy muzak, the horrible elevator music, because it’s cheaper to license than the actual songs. Please don’t do this.
2. Get XM Radio for Business, costing $40/month.
3. Download free music from Jamendo which is under a Creative Commons license.  This music is uploaded by artists that are not represented by ASCAP/BMI/SEAC. I am amazed at the number of high quality albums listed on Jamendo. My Virginia client found lots of great jazz at Jamendo and will play that at their retail store.

ASCAP is Nuts

As a side note, I am all in favor of musicians getting their due. But hearing background music in a store falls under “fair use” to me. From a music business prospective, I don’t think that many people will chose to listen to music in a store as a replacement for buying music. “Hey honey, let’s go to the mall. I feel like listening to some Lady Gaga.” Hearing music at a store promotes music purchases just like hearing it on the radio.

ASCAP goes way too far. They’ve sued Boy Scouts and Girl Scouts for singing camp songs. They’ve sued cell phone users for playing ring tones. They want fees from YouTube for having background music in videos. They want fees from iTunes and Amazon for 30-second song previews. That’s not just silly. It hurts the musicians.

Install it like any Firefox Add-on by going to Tools – Add-ons – Get Add-ons. Once installed you will see a down arrow at the the bottom right hand of Firefox. It turns blue when there is content on the current page that you can download. It’s simple.

After downloading a video, you can use Handbrake to change the video to another format you might need.

Twitter updated their Known Issues page to show that the problem has been resolved. Currently Twitter updates are sent to the Facebook Wall only. Plans are to have it also update the Facebook status.

The Atlantic Monthy magazine has a great article titled The Enemy Within on the history of Conficker and where we are now. It’s a fascinating read for both technical security buffs and non techies.

It starts:

The Enemy Within by Mark Bowden

When the Conficker computer “worm” was unleashed on the world in November 2008, cyber-security experts didn’t know what to make of it. It infiltrated millions of computers around the globe. It constantly checks in with its unknown creators. It uses an encryption code so sophisticated that only a very few people could have deployed it. For the first time ever, the cyber-security elites of the world have joined forces in a high-tech game of cops and robbers, trying to find Conficker’s creators and defeat them. The cops are failing. And now the worm lies there, waiting …

Sheila Bowman of the Monteray Bay Aquarium said that they created a Seafood Watch iPhone app for people to easily find what seafoods are considered good and bad from a fish sustainability perspective. It’s a simple program for looking up fish when you are at the restaurant or grocery.

A new tool that I started using is Zoho Assist. This is web based remote login software similar to GoToAssist or LogMeIn Rescue, but far more reasonably priced. Unlike UltraVNC SingleClick, Zoho Assist works on PC, Mac, and Linux (SingleClick is PC only) and everything can be setup from a web browser (SingleClick is far more complicated and requires the support person to understand firewalls, port forwarding, and dynamic DNS services). Zoho Assist is free with limited features allowing 5 sessions a month, enough for most people helping a few friends and family. The price for the full service is $12/month.

The person you are supporting has to either click a link in an email you send them or go to join.zoho.com and enter the Session ID for the session you created. Then Java is often automatically installed on the supported computer and the person has to click a series of OKs and Nexts. But overall it is a simple process that you can walk most people though on the phone.

I still recommend UltraVNC SingleClick for advanced support needs for PCs. But for something quick and simple, Zoho Assist is a great service.

Expensive bits.
