Summer Time Project – MyRinkFinder.com

Sorry, It’s been about two weeks since I released a post. I have been working on another project that has occupied most of my free time, yet another website. Details to follow!

As some of you know I am heavily involved in youth hockey since both my children are on multiple teams. As manager of the teams each week I am responsible for sending out information regarding our upcoming games to the players and parents to insure they arrive to the rinks on time. In my emails I include all the pertinent information, game time, rink address & location, driving directions and info regarding the rink conditions. Some details you normally wouldn’t find on the internet.

Is the rink old? How cold is it inside? Is it an outdoor rink? Hows the snack bar? You get the idea. Continue reading “Summer Time Project – MyRinkFinder.com”

Which Hard Drive Should I Choose?

Yesterday I spoke about the different “i” series processors offered by Intel and compared them to various model cars from economy to performance. Today I want to talk about the different types of SATA hard drives you might come across when purchasing a new PC or portable backup drive. I don’t want to talk about brand specifics, but rather what kind of performance you can expect out of the different types of disks. I’m a bit of a Western Digital fan boy so I am going to focus on their hardware, however the information in this post would hold true for just about all hard drive manufactures.

The Mechanical Hard Drive

Since its inception in 1956 hard drives have been mostly mechanical devices. Only until recently have SSD (solid state drives) become more main stream and I will talk more about that later. A mechanical hard drive consists of a spinning platter driven by a motor and a magnetic read / write head that can change a microscopic spec on the platter from a positive to negative charge and vice versa. The spinning disk in your computer right now is filled with 0’s and 1’s and when read back from the disk is converted to data. Our pictures, videos and word documents are just a sequence + or – magnetic fields. Amazing!

Depending on the type of drive and its specification will determine how fast it can read and write our files. Mechanical spinning disks are rated at rotation speed, how fast the drive can spin the platter. Faster rotation speeds can equate faster data transfer.

Intel i3, i5, i7, i9. Choosing the best Intel Processor!

It would seem that Intel is now the dominant force in computers when it comes to processors. AMD fought hard to keep up throughout the years but the marketing machine that is employed by Intel has secured their future. Intel is not only great at making quality processors, but also great at convincing the world that their product is the best.

What is a processor and why should I care?

A processor also know as a CPU (Central Processing Unit) is basically the brains of your computer. Most modern CPUs are considered microprocessors, meaning they contain all the circuitry to do the job on a single chip. I’m not going to touch too much on processor theory or history but just understand that all processors are designed to Fetch, Decode, and Execute instructions based on the demands of the programs you are using. How fast and efficiently they complete their tasks all depends on the design and speed of the particular processor.

I like computers and cars – Let’s compare!

Poor WiFi Signal At Home? A WiFi Extender Can Help!

Most homes don’t have network cables running to each room, so many of us rely on WiFi to connect our devices while at home. The problems begin when the ISP installs our router / WiFi box in a less than optimal location, and usually it can not be easily moved. This is where a simple WiFi extender can augment your existing signal and extend the reach of your home network to every corner of your house even the back yard.

How WiFi Extenders Work?

In its simplest form a WiFi extender is just a repeater. The extender is listing for a signal from your home WiFi router and repeats that signal “LOUDER” in an area of your home that is not hearing your main WiFi signal. Basically just relaying the information between your device and the main router. Think of the extender as a “man in the middle”

Where Do I Place My Extender?

The first step to installing a WiFi Extender is obviously setup. Some models have a touch screen to allow for a quick and easy setup. Others can be connected to your PC via USB to input settings or can be connected over WiFi. Once the setup has been completed it is important to select the proper location. You need to find Continue reading “Poor WiFi Signal At Home? A WiFi Extender Can Help!”

Protect Your Computer From Ransomware!

Ransomware! Sounds scary doesn’t it? What exactly is ransomeware and how can we protect ourselves from being a victim?

ran·som

/ˈransəm/

a sum of money or other payment demanded or paid for the release of a prisoner.

That basically sums it up, Money paid for the release of a prisoner and in this case the prisoner is your data. You accidentally visit a shady website, or open an attachment that you maybe shouldn’t have and in an instant the ransomware virus begins encrypting your files.

How does it work?

Don’t believe the hype – MP3 is NOT Dead!

What did we do before MP3? I remember the early years using my Dolby high speed dubbing tape decks to make copies of the tapes my friends and I used to share. Not too soon after came the Compact Disc, and I ran out to buy a Pentium 60mhz with a 2x CD-Recorder to make my mix CD’s.

I was amazed that we could “rip” huge wav files off the CD’s and play them back on the PC. But disk space was at a premium in the 90’s, due to the limited capacity of hard drives.

There had to be a better way to store music! That’s when a friend introduced me to the MP3 format. Full length songs at decent quality only 3mb – 5mb! WOW this was amazing, think of the possibilities. There were no portable MP3 players yet, I found myself taking a laptop in the car hooked to an FM transmitter to listen to my music.

I even marketed a CD on eBay for $10 that had plans for a car MP3 Player Just imagine putting a computer in a pizza box in the trunk of your car, running a PS/2 cable to a numeric keypad and mounting a 40 character display to your dash board with a parallel cable. It was good business until the portable MP3 players began to arrive about a year later.

Weekend Project – Repairing & Emulating the Commodore 64

The Commodore 64 was not only one of my favorite computers it was my first computer. Over the life span of the C64 I broke quite a few of them due to the poor quality of early deigns. This may have been a good thing because it lead to taking them apart and attempting to repair the units insuring my life long love of computers and consumer electronics.

Sometimes I was successful at my repair endeavor and many times not so much. Repairing the Commodore 64 became as much a hobby as programming the computer.

If you still have one of these dinosaurs in your basement and want to fire it up to show the kids take a look at this great PDF file I found on the Internet. It could prove to be helpful.

Feel Free To Download The Service Manual PDF Here

The service manual is dated March 1992 and that was about the year the C64 went out of production. It is actually very complete with lots of hand drawn schematics and theory of circuit operation. Parts numbers and chip / port pin outs are also listed. Basically everything you need to troubleshoot and fix that old computer and fire up the BASIC V2 screen we all remember so well.

How to make an image of your USB drive

Every now and then I stumble across a piece of software that is well written, extremely useful and FREE. Today I’m going to talk about Image USBDuring the day I am responsible for a staff of help desk technicians that are continuously upgrading and repairing PC’s. They like to have their Windows 10 install media on a bootable USB drive. Lately the industry is shying away for optical disk drives, so bootable USB install media is a must.

Why can’t I just copy the files from one drive to another?

To “BOOT” from USB media the disk needs to have a boot sector. Think of the boot sector as a hidden area on the drive that the gives the computer specific instructions that it can only see at startup. Once the operating system is running you can easily copy your files from one drive to the other, however the hidden boot information is a little more difficult

What is special about ImageUSB?
