Storm Season Approaches - Protect Your Technology

Many people feel that the only way to protect their electronic equipment from storms is to unplug them from the wall. While not having something plugged in is the only 100% sure way to protect it from a particular power event, it certainly isn't practical. Additionally, the reality is that many power events happen everyday that we are never aware of. And we aren't always home or awake to unplug everything during a storm. So how does one effectively protect their electronic equipment from power events? The answer is through a quality uninterruptible power supply, otherwise known as a UPS, or commonly referred to as a battery back-up.

In simple terms, a UPS is a surge protector with a battery as a back-up power source. If the UPS detects any sort of power disturbance - such as electrical noise, over/under-voltage conditions, or even a complete blackout - it instantly switches to the battery as the power source. In this way, the devices plugged in to the UPS will always receive clean power, no matter what the disturbance. Of course, the battery can only last so long, depending on its size and how many devices are plugged in, but generally the common consumer models can provide enough power to run equipment for 10 - 20 minutes. This is usually long enough for a short blackout and certainly long enough for those annoying blips in power all too common during the summer months.

The two brands I recommend, APC and CyberPower, both guarantee that their products will protect your equipment even from a lightning strike. These brands are commonly sold at most major retailers and at many local computer stores. If you need help sizing and choosing the best UPS for your needs, please let me know and I'd be happy to help.

Q: Will the new Daylight Savings Time affect me?

Generally speaking, unless you or your company run a time-sensitive application, at worst you will need to manually set the clock on your computer forward an hour. The other exception is if you run software to manage your schedule. If you manage your calendar on your computer (or PDA), you should check for an update from the software developer. Regardless of what you do, simply be aware of your appointments for the first few days of the new Daylight Savings Time and make sure your appointments aren't set for one hour later than they should be.

If you're running Windows XP, make sure you run Automatic Updates (or have run it recently), and your PC should automatically take care of the time change. Older versions of Windows should download and run the utility "EZ Time Zone". This tool is also nice if you need to update several machines across a network, or if you don't want to run Automatic Updates on Windows XP.

If you use Microsoft Outlook, you should download and run the Outlook Time Zone Tool - http://support.microsoft.com/kb/931667

Mac OS 10.4 users should make sure they've updated to Mac OS 10.4.5 or later, and also downloaded the latest Apple DST update. Mac OS 10.3 users should make sure they've updated to 10.3.9 and downloaded the latest Apple DST update. All these updates are available via Automatic Software Update.

Mac OS Classic users should read this article I've written - http://www.marcelbrown.com/techbytes/2007/03/mac_os_classic_and_daylight_sa.html

Palm OS users should download the Daylight Savings Time Update - http://www.palm.com/us/support/downloads/dst_palmos.html

Tech Toy of the Month: Mobile Broadband Internet Router (Linksys WRT54G3G-ST)

What do you do if you need Internet access anywhere, anytime? You probably opt for a mobile broadband Internet service from a cellular company. These types of services allow you to use their networks for Internet data at relatively high speeds through the use of PC card that you insert into your laptop. For most people, having one computer with mobile Internet is enough. However, for mobile groups of individuals, having one computer with Internet access is not enough. Sure, they can each purchase their own PC cards and each subscribe to their own mobile broadband service, but that can get quite costly. So what's the answer?

Enter the Linksys WRT54G3G-ST. This device allows you to share a mobile broadband Internet connection among several computers. Currently, this product only works on the Sprint network, but I expect that more products like this will become available for other carriers. The WRT54G3G-ST works just like a normal cable/DSL router that many of us have in our homes and businesses. You basically plug your Sprint PC card into the router and that connection is available to any computer that connects to the router, either wired or wirelessly.

The Linksys WRT54G3G-ST comes with all the features that one should expect from a modern wireless Internet router, such as a DHCP server, WPA/WPA2 wireless encryption, an SPI firewall, and VPN passthrough. It has 4 wired ethernet ports and also allows you to connect to an existing cable or DSL service if one is available, just like a normal Internet router. Additionally, because all the computers connected to the router are on the same network, they can share files or printers among them as well. Basically, the Linksys WRT54G3G-ST allows you to set up a secure LAN complete with Internet access anywhere you go.

This device could be very useful for companies who send groups to tradeshows. Each individual can bring a computer and have Internet access available to them on the floor of the show. It could also be very useful for companies that send out groups to temporary offices or client sites where they may not have Internet access available to them. Contractors especially work in environments where Internet access may not have yet been installed.

If you have the need for multiple computers to have Internet access anywhere, anytime, feel free to contact me to discuss your options.

Mac OS Classic and Daylight Savings Time

Are you still running Mac OS Classic and are dreading manually changing your Mac's clock for the new Daylight Savings Time? Don't despair, there is still hope! I've found a tool that will allow your Mac OS Classic machine to still properly adjust its clock for the new Daylight Savings Time.

Download the NTP client "Network Time" (http://hyperarchive.lcs.mit.edu/HyperArchive/Archive/comm/inet/network-time-201.hqx). Decrypt the archive and install the control panel into your Control Panels folder.

If you are using Mac OS 8.5 - 9.22, you need to go the Date & Time control panel and uncheck "Set Daylight Savings Time Automatically". You should also uncheck "Use a Network Time Server", as "Network Time" does the same thing.

Open the Network Time control panel and set the various options for your time server and when to set the time. I won't go into details, as they should be fairly self-explanatory, but I believe you MUST set a valid time server, or Network Time will not apply the proper DST changes. It must sync to a time server to activate the new DST info. You can use time.apple.com if you don't have another time server to use.

Network Time can not only set your Mac's clock using NTP time servers, but it can also automatically adjust your Mac's clock for Daylight Savings Time. What we'll accomplish here is to modify when Daylight Savings Time begins and ends for your particular time zone.

There is a drop down menu labeled "Time Zone". Click on the menu and choose "Add/Change Time Zones". A screen will appear listing various U.S. Time Zones. If your time zone is listed, highlight your respective time zone from the list, making sure you chose the one that ends in "/Daylight Time", and click the "Modify" button. You are now presented with options to change the starting and ending dates for Daylight Savings Time. Change the starting date to the 2nd Sunday in March, and the ending date to the 1st Sunday in November. The time should remain unchanged at 2:00 AM. Click OK in this window and the previous window. You should be back at the Network Time control panel.

Now one last step (and this is extremely easy to forget, so don't forget) - click the drop down menu for "Time Zone" and choose your respective time zone (the one you just modified and again, make sure you choose the one that ends in "/Daylight Time").

If you do not live in the U.S., then you will need to create a new time zone, or modify one of the U.S. time zones to meet your needs. The details are up to your particular area, but you should be able to use the above instructions as a guide.

Once you've made the above changes, press the "Set Time" button at the bottom of the window. You can verify that the time was synchronized by looking at the "The time was last set" info next the the button. If the time doesn't sync, verify you used a valid time server. Again, if you don't know any time servers, you can use time.apple.com.

Now that you've changed the DST starting and ending dates and chosen your time zone from the Time Zone menu, your Mac running Mac OS Classic should automatically adjust its clock properly for the year 2007 and beyond (at least until they change DST again).
