The choice of mp3 players is growing before our eyes. Their generations replace one another, the devices become smaller and smaller in size while their memory expands. The recipe for dream player is actually simple, but it requires the professional approach: a minor mistake may spoil the entire product. Blend voice recorder, radio set and audio file player (the more formats it supports the better) and then add as much built-in memory as possible on ?never too much of a good thing? principle. Pour the mixture into small spiffy moulds and sprinkle it with buttons and connectors.
Now that we know the ingredients for the stuffing we can examine some crucial points. The increase of memory capacity presents some challenges as to compatibility of players with USB 2.0. Active lifestyle requires some kind of time management, and one just cannot spend hours waiting for half gigabyte file to upload to player.
Do not forget also about convenience delivered by handy controls and standard USB ports. It is really inconvenient to carry all those connection cables with you, so you may want to choose the model with either standard USB slot or Mini-USB.
When choosing a player one should take into account some factors that are crucial to its performance.
Certainly, the first important factor is playback quality. It does not differ much in various pocket mp3 players offered today. However, some models perform better than others. Remember also that audio quality depends to great extent on the headphones, and not only on the player itself.
The second characteristic to be taken into account when selecting an mp3 player is the menu friendliness and available settings. It is important that user can change settings on the move.
Multi-purposeness and command processing speed are also of great importance. It would be ideally for user to upload and copy the files using one player.
Lastly, additional functions and value for money criterion should be assessed. Not everyone needs FM-radio or voice recorder, so why pay for the functions you are not going to use?

One of the handy uses of the FileSystemObject is to manipulate text files. In this article I will discuss the methods related to creating, modifying and reading text files. This is especially useful when gathering information or logging the progress of a task.
The role of the FileSystemObject in working with text file is to return a TextStream object which in turn has the methods required to read and write data to text files. The TextStream can be opened in one of three modes namely read, write and append.
To enable the use of friendly names for these modes add the following constants to your script:
Const ForReading = 1
Const ForWriting = 2
Const ForAppending = 8
Next step is to create an instance of the FileSystemObject:
Set objFSO = CreateObject(’Scripting.FileSystemObject’)
It is important to understand that whether you read, write or append to a text file the OpenTextFile method will be used. This is because the FileSystemObject returns a TextStream object which in turn exposes the methods needed to work with text files.
Textstream in read mode:
Set objTextFile = objFSO.OpenTextFile(’c:somelocationsometextfile.txt’, ForReading)
Textstream in write mode:
Set objTextFile = objFSO.OpenTextFile(’c:somelocationsometextfile.txt’, ForWriting, True)
Textstream in append mode:
Set objTextFile = objFSO.OpenTextFile(’c:somelocationsometextfile.txt’, ForAppending, True)
Read text file line for line:
Do Until objTextFile.AtEndOfStream
strLine = objFile.ReadLine
Loop
Read entire text file:
Do Until objTextFile.AtEndOfStream
strLine = objFile.ReadAll
Loop
Write line to a text file:
objTextFile.WriteLine(?Hallo world?)
After working with text file it is important to close the file.
objTextFile.Close
Note that the True value that is present in the write and append mode means that the text file should be created if is doesn?t already exist.

Whether you?re professional photographer or a tourist looking to record a few good memories, the first step to great photographs is a finding a decent camera.
One of the first decisions you need to make is whether to go with a quick and convenient digital camera, or stick with trusty old film.
The main benefit of going digital include the ability to see pictures instantly on an LCD screen, saving the ones you like and erasing the ones you don?t. Another advantage is the versatility of being able to edit and perfect your photos on a computer, using a program like PhotoShop.
There are also immense economic advantages to using a digital camera. Being able to review each picture you take, and print only the ones you really like saves a lot of money that would have gone into buying film and developing poor-quality pictures.
Despite these tempting benefits, however, there is still a case for sticking with good old fashioned film photography.
The image resolution, for example, is generally better with a cheap traditional camera than a mid-range digital camera. In order to achieve true film-quality resolution on a digital camera, one must pay several hundred dollars for a 7+ megapixel device.
Another advantage of film is its distance from the world of computing technology; even a person who is totally computer-illiterate should be able to use a traditional camera to its full potential with no problems whatsoever. Furthermore, many photographers prefer the simple challenge of taking a good picture on film to the much less artistic process of ?cheating,? and editing pictures on a computer.
Overall, the right type of camera depends almost entirely upon the photographer. Each person must choose for themselves which kind of photography they like better.
Another option, of course, is to buy both digital and film cameras, and alternate depending on situation. This is often the best choice for a serious photographer who can afford the additional expense.

In the past few years, a great number of businesspeople, professionals, and ordinary consumers have been purchasing ?Personal Digital Assistants,? electronic devices designed to organize and simplify one?s life.
The first PDAs, which hit the market in the mid 1990s, were little more than glorified notepads, making it possible to store a record of notes, phone numbers, calendars, and day-to-day appointments on an electronic device. These devices gradually evolved over the years, and Palm Inc.?s popular Palm Pilot devices gained a loyal following of both consumers and enterprise-level users.
New features, including 3D games, multimedia applications, and even Wi-Fi internet access have become commonplace on modern day PDAs, making them both practical and entertaining.
As time goes by, however, the functions performed by PDAs are being slowly but surely integrated into the many advanced cellular phones and mobile email devices now on the market.
This has led to a significant decline in demand for standalone Palm Pilots and Pocket PCs, which are increasingly being replaced by smartphones, converged devices which integrate mobile computing with wireless communication.
Most new smartphones serve as fully functional cellular phones, while integrating many of the features of a laptop computer. Each device comes equipped with its own operating system, along with a wide range of software applications specially designed for mobile devices. They are also capable of accessing the internet, usually over a cellular broadband connection, and can be used to check one?s email when on the go.
Although the cost is somewhat prohibitive for the majority of consumers, smartphone PDAs have become an institution among enterprise users, and are now a necessity for many mobile businesspeople.
All in all, PDA manufacturers are doing a good job of evolving with new technology, and providing users with an increasingly efficient and functional experience.

Chances are that if you have used your Windows PC for any length of time, you?ve noticed that its performance isn?t as snappy as it once was. Some of the slowdown in performance could just be simple wear and tear. Some could be caused by a lack of space on the hard drive from all the programs you?ve installed. A large part of it could be problems in your Windows System Registry.
Windows System Registry? What?s that?
The system registry is a database used by Windows to store everything it ?knows? about your PC. In one sense it?s a map containing the locations of every file and program on your computer. In another sense, it?s a history book, keeping track of every program installed, modified, or removed during the life of your PC. In yet another sense, it?s a photo album containing ?snapshots? of your computer?s present condition.
All the programs on your PC use the system registry to store information, receive instructions, and to make modifications. All of this is done ?on the fly,? with programs and processes all running to the system registry for information. Picture the registry as a very busy secretary with all kinds of demands made on its time and resources. It?s very easy to see that after a while, that database of information can become bloated and disorganized.
Any number of things can lead to registry problems including regular usage, improper shutdowns, and programs that fail to properly uninstall.
How can cleaning the registry help?
In order to keep your computer running at its best, its system registry needs to be reorganized every now and then?about once a week. Again, imagine the busy secretary. In order to meet the needs of everyone coming into the office, it helps if all the information was organized and easy to find, but with everyone coming into the office all the time, that?s hard to do. Sometimes information gets duplicated. Sometimes it gets misplaced. Sometimes, it might even be lost all together! All of that can result in slower system performance. Taking the time to ?straighten up the office,? or clean the registry will help improve performance.
What are some of the signs that a good registry cleaning is necessary?
Signs of a registry in need of repair include:
- slow boot up
- system hang-ups at start up or shutdown
- error messages during boot up
- error messages during shutdown
- missing .dll or .exe error messages
- failure to boot
- individual programs hanging up, freezing, or crashing
- system-wide crashes
The list can go on and on, and sometimes can be misdiagnosed as a virus problem. In fact, viruses can also cause problems with the system registry. If a virus scan does not fix your PC?s problem, a system registry cleaning is most likely in order. How do I clean the system registry? When it comes to cleaning your Windows system registry, you have two choices: you can do it yourself, or you can use a system registry cleaning program to do the work for you. The first choice?doing it yourself?is cheapest in the short run, but not recommended. Going through the registry yourself is a tedious process, and unless you know what it is you are looking for, it can also be very dangerous. You could end up rendering the system registry invalid and that could prevent your PC from booting up at all. It could even require that you completely reformat your hard drive and start from scratch. The cost in time, lost data and frustration just isn?t worth the effort.
Using a good registry cleaner with features you can manage is definitely the better options.
What will a good registry cleaner do?
A good registry cleaner will do the following:
- check/repair application paths and shortcuts
- check/repair shared program paths
- check/repair file associations
- check/repair Active X controls
- fix your Add/Remove programs file
- check help, font, and most recent files
- check/repair shared DLL files
- check startup programs
- describe problems
- backup your registry
Cleaning the registry should be a regular part of your system?s maintenance along with defragmenting your hard drive, and scanning for viruses. By including a regular system registry cleaning in your regular maintenance, your can keep your PC in top condition for a long time to come.

After a less than spectacular start, the computing world has discovered the Tablet PC.
Four yeasr after Microsoft’s Bill Gates first introduced it, the Tablet PC is now being embraced by medicall professionals, salesperople, students, journalists and everyday consumers who want to get a full-featured portable pc with the extra ability to be used like a pen and a tablet of paper,
Small, lightweight and rugged, these powerful machines are branded by well-respected manufacturers and consumers can chose between the Gateway Tablet PC, the Motion Computing Tablet PC, the Fujitsu Tablet PC, the Toshiba Tablet PC and many other rugged tablet pc types.
Tablet PCs come in two configurations: the slate model pc tablet, which is like the old childhood etch-a-picture toy. You use a tiny pen-stylus device to write on the surface of these tablet pcs, with your handwriting digitally converted and showing up on the screen just like it was a piece of paper.
Then there is the convertible model tablet pc. It is a tablet pc laptop in form, combining a screen which can be turned around to cover the keyboard and used just like a slate model tablet pc or, when flipped upright, the screen works just like a laptop computer or notebook computer.
The weight of these tablet pcs ranges from around 2 pounds for some fujitsu tablet pcs to over 6 pounds for some of the HP Tablet PC models.
Shopping for a new tablet pc is best done online. Although some of the large box computer stores carry tablet pcs, the best selection is found through the many specialized sites, which often offer tablet pc comparisons. You can also find the cheapest tablet pc for you by shopping online.
Expect to pay between $1,000 and $2,000 for an average model with a 40GB hard drive, wireless wi-fi capability and an ethernet port. To get a larger hard drive (I recommend 60GB) and an upgraded screen optimized for indoor and outdoor viewing, you’ll have to pay close to $2,500.

Many times I have stared at my computer thinking ‘How do I fix my pc because it keeps crashing?’
Unfortunately there is no simple answer! I used to think this problem was related to buying cheap computers but after buying various laptops and desktops at different price ranges there is one common theme, eventually they will all crash at some stage!
Friends will often think I am a pc expert and will call me asking ‘How do I fix my pc when it keeps crashing?’ Well start by asking yourself these questions…
Have your children be on the pc? Kids are great at downloading spyware by mistake! They will also click on numerous pop up pages and will often change your settings!
Another possible reason your pc keeps crashing is that you have overloaded it! If your pc only has 64mb RAM memory and you install graphic, gaming and other software the chances are that your system will not be able to cope with your software! Most PC’s now come with at least 512mb RAM so it is worth upgrading if your pc is not at this level.
However the most common reason that your pc keeps crashing is that it has a virus! Many trojan virus can cause your computer to reboot immediately once all programs have been launched, this can drive you mad and it is not fun as you are helpless!
Best option is to install anti virus software and make sure you only visit trusted websites. If all else fails it is time to reformat your hard drive and wipe your pc clean, this can take hours and you will probably need the data recovery disc that you should have got when you bought the pc.

As baby boomers we expect much from ourselves, the world around us, and especially technology. What I found was technology has not caught up with affects of a longer life has on the brain, life style, and medical awareness. With all of the new medications and attention to medical care, many individuals live longer with chronic illnesses such as diabetes, MS, heart problems, etc. The brain can and often does still suffer from the affects of these diseases with damage to the frontal lobe of the brain that controls executive function and cognitive abilities. Executive function controls your ability to make and apply lists of things to do, organize your daily activities, make decisions, initiation of tasks, and emotional connections.
Your brain needs 3 important things — blood, oxygen, and glucose to operate. The lack of any of these things and the brain starts to die. The lack of any of these takes a real toll on the frontal lobe. I never knew my glucose was low, I never had any warning signs — I did not know anything was wrong until the lack of glucose was doing the damage to my brain at the molecular level.
What was my life like before my brain injury? I was a go-getter. I was involved in my job, church, hobbies, self-employed, writing a book, children, grandchildren, and hobbies.
What’s my life like now? I had to retire from work on disability at the age of 49. My relationships changed because I can’t always feel emotions or connections to others. I have problems with executive function (the front part of your brain that plans, organizes, and executes daily activities), gait problems ( I have fallen 5 times in 3 year once breaking my leg) vision problems (sensitive to light and blurred vision) immediate memory (memory that allows you to hold on to enough information to problem solve a problem or remember a phone number long enough to dial it) visual memory (I can’t look at a pattern or other information and then apply that information) and other problems.
What can technology do for us? I have heard many physical therapists agree that cognitive therapy does not work. I don’t believe that because I have seen improvement in my life by participating in a work day program for brain injured individuals (The Denbigh House of Newport News Virginia). What all my therapists, doctors, rehab personnel and what I have experienced is compensatory strategies do work. Since my brain injury is mild I couldn’t find a rehab group that could help me. They all said since I could make a list I was fine. They don’t realize that making a list and using a list are two different things. I finally after two years of working by my self worked out a set of lists that kept me on track for my daily activities and household chores. However when I decided I wanted to become a public speaker and have a web business my lists didn’t work anymore and I can’t take two years to figure out lists again. The lists would also be too cumbersome to work in a real world setting anyway. So technology it is.
I was a computer specialist before my brain injury and still know what I used to know even if I can’t always execute it. So what I am trying to do now is work with a rehab facility that is doing a study on brain injuries and the ability to live more productive lives with the use of handheld devices like palms, blackberry’s or pocket pc’s. I am anxious to see what this will do for me and will keep the blog informed of how it works. I am hoping that I can get a device that I can add all my contacts too and what they mean to me, how to do certain things ( like I can never remember how to add a picture to my web site and have to look it up every time), alarms to take medication, to rest, and so many other ways I need an alarm to keep my life balanced, and to be able to keep my information I need right at my hand so I can access the information in a timely fashion. I am still waiting to see if I am part of the study so for now I am working on a disorganized set of lists.
I am a brain injury survivor. I was not in a car crash, hit my head, have a stroke or heart attack — my brain injury was brought on by my blood glucose dipping so low that it caused a permanent brain injury at the molecular level. I am not diabetic but I had gastric by-pass in 1999 and in the year 2000 I started having problems keeping my blood glucose under control. Not every one who had a gastric by-pass will have this problem but my neurologists said they are starting to see more of this kind of problem with the higher numbers of this surgery being done.
