home and office computer support for D.C., Virginia & Maryland
At Tech DC, we regularly set up home theater systems for people. We rely on Monoprice for all our cables. They are great quality and only a fraction the cost of cables from big box and other retail stores.
Local retail stores try to sell a HDMI video cable for $50 with every TV. See the HDMI cable selection at Monoprice showing equivalent cables for $10-20.

From a Best Buy advertisement in the Washington Post:
If you have computers or electronics that you don’t want to be killed by power fluctuations, it’s a good idea to have a UPS (Uninterruptible Power Supply). The battery in the UPS keeps your equipment running through blackouts our brownouts (reduced power).
Dead Battery
The main problem with a UPS is that its battery might only last a couple of years. A dead battery is often announced by a UPS through regular beeping. Because a UPS is expensive, consider just replacing the battery instead of the whole UPS when the battery dies.
You can buy a replacement from the UPS company or for significantly less money from a third party such as Battery Mart. Just be sure to get a battery that is designed for your specific UPS. I have had good luck with with Battery Mart, but there are some third party batteries which are of poor quality, possibly having a short life, acid leakage, or even causing a fire.
I replaced the battery for the APC Back-UPS 500 ES for $26.39 from Battery Mart instead of $48.99 from APC (prices include shipping).
The original Palm OS is dead. The company did not make a big deal about it, but they just recently stopped production of all older Palm devices that run the original Palm operating system (OS). Instead, they are focusing on their completely new WebOS used in the Palm Pre and upcoming Palm Pixi. While this is no surprise given how the company needs to stop hemorrhaging cash, it is still sad to see this venerable operating system gone with such little fanfare.
Palm’s CEO Jon Rubinstein said:
We’re launching more great Pam WebOS products with more carriers, and turning our sights toward growth.
What Made Palm OS Special
Born in 1996, the Palm OS had three main things that made it special in my view:
1) Graffiti: The Palm OS had a modified version of handwriting character recognition called Graffiti. Unlike Apple’s earlier ambitious attempt at full handwriting character recognition in the Apple Newton, the Palm worked simply and reliably.
2) Applications: The Palm could load applications and games that you downloaded and installed yourself. This was before the concept of a closed-off Application Store, such as the for the iPhone or Palm Pre. Palm OS’s approach was less elegant than the modern app store, as many apps crashed and there was no single location to buy apps. Still, there were over 50,000 applications available online, more than any other PDA had at the time.
3) Synchronization: Unlike the Sharp Wizard or other pocket organizers, the Palm had sync software called HotSync which could deal appropriately with updates from the computer (using Palm Desktop) and the Palm. Although it wasn’t fancy, the synchronization worked great.
Corporate Fun
The corporate maze that Palm and the Palm OS went through was amazing.
Before the Palm OS’s development in 1996, Palm Computing Inc. was bought by US Robotics in 1995. US Robotics was in tern bought by 3Com in 1997. Palm was then spun off to its own company in 2000. In 2002, the Palm OS part of the company was made a subsidiary company to Palm named PalmSource. PalmSource (makers of the OS) then spun off to a completely independent company and licensed back the OS to PalmOne (hardware maker). In 2005, PalmSource was acquired by a company named ACCESS who then licensed it back to Palm, Inc (hardware maker, formerly PalmOne) in perpetuity.
As if that weren’t enough confusion, the original inventors of the Palm Pilot were frustrated and started their own company called Handspring in 1998. They made a competing device running the Palm OS called the Handspring Visor. In 2002 they started the successful Treo line, which weren’t yet phones. In 2003, they merged back with Palm (hardware maker) and formed PalmOne.
Sony also sold Palm OS devices until 2004.
OS Development
All this craziness hampered the development of the OS, but there were updates to the OS over the years. The last released version, 5.4 (Garnet), supported WiFi, Bluetooth, and multiple screen resolutions. However, the Palm OS was still not scalable or modular compared to Windows Mobile or the current Apple iPhone OS which competed recently with the Palm OS in Palm Treo phones.
Palm OS 6.0 (Cobalt) was announced in 2004 and was actually a completely new OS based on the acquired assets of BeOS. This was an attempt to truly evolve the OS. It provided modern features: multitasking, memory protection, and better graphics. This iteration of the OS never saw the light of day, however, as it did not get any interest from manufacturers and was never used in any devices.
Because the Palm OS was antiquated, Palm started selling both Palm OS and Windows Mobile versions of their Treos in 2005. Along with recently stopping production of Palm OS devices, Palm has just stopped production of all their Windows Mobile devices.
WebOS was announced in January 2009 and has now replaced Palm OS. If you need to run some old Palm OS applications, there is a third-party emulator called MotionApps Classic that runs the original Palm OS within WebOS. With the rapid adoption of WebOS and the Palm App Store, most people won’t need this.
Palm’s CEO Jon Rubinstein said on their August 28 2009 earnings call:
We had a really unique opportunity in being able to develop Web OS.. and the old Palm OS lasted us for 16 years, which is really amazing when you think about it. We are designing Web OS to last us for the next 10 or 15 years.
Off to OS Heaven
Although Palm OS has had a difficult life, it’s been the most dependable pocketable operating system for me until a few years ago. From my first US Robotics Palm Pilot 5000 to my Palm Vx (my personal favorite) to my Palm Tungsten 5 with color and WiFi, the Palm OS has been a great companion. It is now part of OS history, off to join other notables such as IBM’s OS/2 and the AmigaOS.
Snow Leopard
The latest version of Mac OS X is out, already with a system update available. It costs $29 but you can find it cheaper at places like amazon.com
The Good
The behind-the-scenes components have been optimized to be far more efficient. For apps that are designed to take advantage of the new OS, they are significantly faster. For now, that mainly means Apple applications like Mail or Safari. Boot time and resume time are also much faster.
There is a new dock expose feature where you can hold down on an app icon in the dock to see all of its windows only in expose. This can be handy if you have a lot of open windows and only want to see those of a particular program. This is one of the very few new features since this OS is mainly just background improvements.
Several of the OS enhancements are not being taken advantage of yet by third party application providers. Once snow leopard versions of programs come out, the benefits will become far more prominent. The new OpenCL feature is particularly interesting. Typically your powerful graphics card is not doing very much. OpenCL allows programs to perform calculations that would normally be done on the CPU to also be done on the video card. For many tasks, this could result in massive speed improvements. Only time will tell how many developers take advantage of this but it seems likely for the big developers like Adobe to do so.
The Bad
Besides Apple apps, most programs don’t seem much faster. In fact, some seem a tad slower, probably in need of a snow leopard built version. In the worst case, there are some applications that don’t run in snow leopard at all. Some of the more notable ones are older versions of Photoshop or Parallels.
Since installing snow leopard, I’ve seen an odd behavior every few days where the transparent menu bar becomes opaque white and the system becomes quite sluggish for no apparent reason with no programs using up a lot of resources. Only a reboot resolves things. This is very un-Mac behavior. This is an upgraded system that has been migrated from other Macs a few times so it is possible it just needs a fresh install of the OS from scratch but that just makes me feel like I’m using Windows again. I’ve only seen this on one system, a current model Mac Pro.
Perhaps the worst thing about Snow Leopard is just that it isn’t a major change and there isn’t much obvious benefit besides some current performance improvements while waiting for programs to further take advantage.
Conclusion
Snow Leopard will probably be pretty sweet once there are more programs built to fully use it. In the mean time, I do enjoy the fastest browser I’ve ever used and having my email pop up instantly. You definitely can’t argue with the $29 price. However, there’s really no rush for most users to upgrade. Waiting a few months is probably more than fine so you can give developers time to make necessary changes.
What should be important to you when buying a flash drive, besides capacity? Speed and reliability.
Amazon and Newegg provide useful user reviews that can alert you to drives with high failure rates. I also look for good read and write speeds.
Read and Write Speeds
Speed tests can be calculated manually, but I used HD_Speed software to determine speeds of these common drives.
| Size GB | Read MB/s | Write MB/s | |
Kingston DataTraveler I |
8 | 17.8 | 7.8 |
| SanDisk Cruzer Micro |
16 | 24.9 | 5.2 |
| Corsair Flash Voyager |
16 | 28.8 | 6.9 |
| Kingston DataTraveler 200 |
64 | 28.6 | 10.7 |
The speeds will vary depending on the size of the files transferred (block size). Larger files can be moved more efficiently than smaller files.
As you can see, the write speeds lag the read speeds. The latest generation of flash drives, such as the Kingston DataTraveler 200, are often significantly faster than older models.
Fast read speeds do not always translate into relatively fast write speeds, as demonstrated by the SanDisk Cruzer’s slower write speed than the Kingston DataTraveler I.
Speed should be more important to you when looking at larger drives since you’ll really notice it when moving more data. People didn’t tend to worry about the speed of 3.5 inch floppy drives when they only held 1.4 MB of data.
Counterfeits
Another thing to watch for is counterfeits. Apparently there are several counterfeits of the Kingston DataTraveler 150 64GB
