A Look at Desktops

Filed under: Belton Journal, Info Bytes — pmckinley @ 8:00 AM

This week we’ll look at desktops in order to compare them to the laptop discussion from last week.

One major difference between laptops and desktops is that the laptop has the display built in. There are exceptions to that, I believe both HP and Dell sell desktop computers that have the CPU built into the display. This is helpful in terms of reducing the real estate consumed by your computer, but it also means that if something goes wrong with the display you can’t just go buy a new display — you have to have the current display repaired, which will likely cost more than a new standalone display. This shouldn’t be too much of a problem — LCD displays tend to be long-lived and trouble-free.

I have found that desktops tend to be cheaper than laptops for equivalent horsepower. Just last week my favorite office supply had laptops on sale cheaper than their cheapest desktop. The catch was that their cheapest desktop was a quad-core (4 cpu’s) and 6Gb memory, 1Tb disk, compared to the laptop that was a dual-core, 3Gb, and I think 500Gb disk. You also have to figure in the cost of the display, but if you’re upgrading you may already have a display and don’t need a new one.

Another advantage for a desktop is that they generally have one or more “PCI” card slots that can be used to add functionality to the desktop. This may or may not be an advantage. For instance, it may be that the feature you need to add to the desktop is a wireless network or bluetooth, both of which are generally a built-in for laptops these days. Another possibility would be a multi-display capable display card, which would allow you to run 3 or maybe more displays. If you needed that capability, you definitely wouldn’t be able to do it with a laptop.

One thing to watch out for in a desktop is how noisy it is. I have chronic tinnitis (ringing in the ears) that I at least partly attribute to spending too much time around computers with noisy fans and/or disk drives. Most of the current crop of desktops are built to run fairly quietly, but some might still be noisy enough that you wouldn’t want it sitting on top of your desk where you’ll have to be listening to that whirr all the time. A potential solution might be to put the computer under your desk. I recommend that you don’t put it directly on the floor, because it will collect too much dust. Dust in your computer tends to clog the heat exchangers that keep your computer components cool. The dust can also get into the bearings of the fans, which will shorten their life as well as create noise when the bearings start to wear out. The better thing to do is to find something you can use to lift the computer a few inches off the floor. There are computer stands, some with wheels and some that attach to the underside of the desk, to do just that. Such a computer stand would be a good investment.

A Look at Laptops

Filed under: Belton Journal, Info Bytes — pmckinley @ 8:44 AM

Do you remember the old “luggable” computers? I remember such brands as Osborne, Kaypro, and believe it or not even Compaq was in the early fray of portable PC’s. I’ve had friends who worked at both Kaypro and Compaq back in the day. The name “Compaq” referred to the fact that their luggable was “compact” compared to their competition. With the advent of LCD displays, it became possible to integrate the display into a notebook-sized computer. Some of the earlier notebooks were quite expensive compared to desktop computers, and weren’t as powerful. Nowadays there are notebooks that are very powerful and yet quite reasonably priced compared to desktop computers.

Even though there are some economical choices for laptops, they do tend to be a bit more expensive than desktops. This is somewhat offset by the fact that they come with a built-in display. However, unless you have a really huge laptop (more $$), the display is going to be a bit small. Most if not all laptops have a display connector that allows you to add an external display. This can be handy when you’re working from home or at the office, as you can usually set it up to use both the built-in and external displays which combine to provide a lot of display real estate. I have a 19″ external display that I use in my home office, which I couple with the internal display. The 19″ display is enough bigger and brighter that I tend to use it for the primary display, using the built-in display for windows that I need to watch, or as references. For instance I might have a second browser window, with information I need to write the Wizgidget article. I tend to have a zillion windows open all the time, so more display is better for me.

Another potential issue with the laptop is the keyboard/mousepad layout might not be the most convenient for you. I use one of those “ergonomic” keyboards that has the keys split into two groups — one for each hand — with the groups at a bit of an angle to each other and slightly elevated in the middle. This configuration allows me to keep my wrists straight when I type, which helps prevent carpal tunnel syndrome. If you aren’t a touch-typist, this won’t matter much as hunt-n-peck typists tend to move their whole hand rather than just their fingers when they type. My hands stay more-or-less still while my fingers “do the walking.”

One thing that I find especially helpful is the docking station. Unfortunately the lower-end laptops aren’t designed to be dock-capable although there are “universal” docking stations available that simply connect to your laptop via a USB cable. Some of them have display capability. My laptop has a dock: when I come home from a trip, I plop the laptop down onto the dock, which connects it to my ergonomic keyboard and mouse, external display, external speakers, network, power, and a host of usb-connected devices. It has the capability of housing a CD drive and a PCMCIA card device. There was a fancier dock available that could house an internal hard disk, that served as network storage even when the laptop wasn’t docked.

Configuring a New Display

Filed under: Belton Journal, Info Bytes, Tips & Tricks — pmckinley @ 8:00 AM

This last week we bought a new display for Ann’s PC. Her old display was having problems, and our favorite office supply store had a 21″ widescreen display on sale for $100, plus we had a customer-loyalty coupon for $20, so that brought the total cost down to $80 or so plus tax.

The new display is capable of 1920×1080 (equivalent to HD 1080P), however when I hooked it up for her, windows XP only seemed to recognize a much lower resolution. This was using the Windows 7 display configuration, accessible via a right-click in the screen background, then pick “Screen Resolution”. In Windows XP this would be the equivalent of a right-click in the screen background, then pick Properties, then pick the Settings tab in the Display Properties dialog window that pops up. Ann’s new display is supposed to be a “plug and play” display that windows can recognize, but for some reason Windows 7 wasn’t recognizing it.

Her PC is a Compaq desktop tower we bought at the same office supply last Fall has an NVIDIA graphics card that has a configuration utility. It turns out that the configuration utility has a feature that allows specifying a custom screen resolution. This utility is accessible via the same right-click in the background, then pick “NVIDIA Control Panel”. My HP laptop has a similar option labeled “Graphics Options”. By setting a custom screen resolution in the configuration utility, she was now able to set 1920×1080 as the screen resolution. Windows allows a test of the new configuration, if it doesn’t work and you don’t click the “ok” button, it will automatically revert to the previous configuration in 15 seconds.

Now that she has her new wide-screen display working properly, she found a new background image out of the canned images available with Windows 7 to go with her wide screen — it’s a vine-covered cottage with a stone bridge over a river in the foreground and forested hills in the background. She was asking how to put her own graphic on the background as she’s seen some people do. This is pretty easy.

First, I’d suggest using an image-editing tool to format the image you want to use to be the same resolution as your screen resolution. It’s always better to use a higher-resolution image, and resize it down, than to upsize a lower resolution image. When you have the image the way you want, save it as a BMP, GIF, JPG or PNG image in a folder that makes sense.

Then, for XP users, right click in the background to get the Display Properties window, then pick Desktop. You’ll see a “Browse” button to the right of the list of canned background images, by clicking that button you’ll get a file browser window where you can navigate to and pick the image you created. For Windows 7 users do the right-click in the background, pick “Personalize”, then pick “Background” at the bottom of the window that appears.

In other news, I bought a Mac Mini on Ebay, to support son Jesse’s interest in developing applications for iphones and ipads. Hopefully I’ll have some hints and kinks for Apple users as we get familiar with that platform.

iPhone, youPhone, Smartphone, Dumbphone

Filed under: Belton Journal, Info Bytes, News, Weblog — pmckinley @ 8:00 AM

When I got a new iPhone 4 a week or two ago, I offered my old ATT “Tilt” smartphone to son Jesse. It’s 3-year old technology, but better than his old “dumb” phone. Potentially he can store the numbers he wants to remember (all 5 of them), as well as calendar reminders which is handy for his college classes. He doesn’t want to pay the $15 for the minimum 200Mb data plan. We figured we could just put the SIM card (a fingernail-sized card that stores the phone’s network “identity”) from Jesse’s old phone into the Tilt, but that didn’t work. So, we took the phone to the local ATT store, and had them switch his phone number over to the new phone, replacing the SIM card in the process. That was fine until ATT decided that since he now had a smartphone he also had to have a data plan, and automagically added the data plan to his phone. It took another trip to the ATT store to straighten that out. Apparently whenever the SIM card is changed in a smartphone, it cues ATT’s systems to add the data plan.

When I was using the Tilt, I had installed an application called “Walking Hotspot” that turned the phone into a mobile “hotspot”, that is, it served as a WiFi access point serving up to 5 wireless devices, and using the cellphone internet access. This was really handy, except that it ran down the battery on the Tilt. Even if I had the Tilt plugged into the charger, it would still discharge the battery. I couldn’t leave it turned on all day, but rather had to just connect long enough to download email and maybe do a little research on the web. That wasn’t very practical except in emergencies, so I had bought a USB broadband card for my laptop last September.

The new iPhone 4 has “hotspot” capability also, at least so the ATT salesperson said. What they didn’t tell me was that activating the iPhone 4 hotspot requires a $45/month data plan. I’ve found they tend to leave out little details like extra costs, to do this you need that which costs, etc. It turns out in this case that it’s a better deal than what I had. I was paying $35/month for 200Mb on the broadband card, plus $15/month for a 200Mb data plan on the iPhone, for a total of $50/month to buy a total of 400Mb of data access. The $45 plan was for 4Gb of data (10 times as much), and eliminated the need for the broadband card. That’s assuming the iPhone hotspot doesn’t burn the battery like the Tilt did.

One little trick I did with the iPhone hotspot is to set Ann’s iPhone to use the WiFi hotspot on my phone to access the internet. So, when we’re together, instead of burning her 200Mb data like we did on that first iPhone road trip, she uses some of my 4Gb data allotment, and saves hers for when we’re not together. At home both phones use our home WiFi of course.
