Planning for Future Blog Posts...

I am planning for several future posts on my blog here at Blogger.

Yesterday, I spent some time using the Snipping Tool on Windows to capture maps of hiking routes from the All Trails website.

Since I have dozens of photographs that I took while hiking on various hiking trails here in Maricopa County over the past couple of months.

My goal is to create posts about hiking that consist of the following:

  • Map of hiking route or area
  • Narrative of what occurred
  • Photos taken along the way

The idea is to expand upon what I would normally do when I make a post to Facebook about hiking or riding my bike.

The difference would be that I can go into greater detail than I would in a Facebook post.

Looking over my blog, I haven't forgotten about some previous posts that need to be re-written and/or started from scratch all over again.

Yes, I need to re-write my post about the song "Seoul Music" by the Yellow Magic Orchestra.

Yes, I need to FINALLY write my LONG-AWAITED posts about movies that I saw at the Cine Core movie theatre in Seoul, South Korea.

Of course, this will take time and effort to accomplish.

Plus, I cannot butcher myself about my posts not achieving some high standard achieved by other bloggers.

It's an easy pit to fall into.

Stay tuned.

Types of Copper Cabling

This afternoon, I made some progress in my new online course over at the Cisco Networking Academy.

Thus far, I am at section 1.3 Copper Cabling in the "Network Addressing and Basic Troubleshooting" online course.

Copper cabling consists of the following:

  • shielded twisted pair (STP) cable
  • unshielded twisted pair (UTP) cable
  • coaxial cable

When you think of cables used in computer networking, you are probably thinking of STP and UTP cables. These two cables are commonly referred to as Ethernet cable.

Coaxial cable is the kind of cable that is typically used for cable television.

Fiber-optic cable consists of a strand of glass encased in wire, so it will be covered in a later section.

Progress is slow.

The topic might be beaten to death, yet it is a good idea to review the different cable types used in networking.

Believe it or not, technology does change when it comes to networking cables.

As always, I am taking copious notes.

Yes, I am familiar with the saying "If everything is important, then nothing is important".

I am probably permanently scarred from both CompTIA A+ certification exams where anything and everything can be a test question.

Based on my experiences with two previous online courses, Cisco isn't much different from CompTIA.

Back to studying...

New Hiking Boots and Hydration System...

Last week, I found myself making the long drive from my mom's house in Sun City to the REI store located in the Paradise Valley area of Phoenix. It's a long drive no matter what route you take. Usually, I drive east along Thunderbird Road to Cactus Road to the Paradise Valley Parkway. This time, I drove east on Bell Avenue through Sun City, through Peoria, through Glendale, through Phoenix until I got to Tatum Blvd. From there, I drove down Tatum Blvd until I got to the Paradise Valley Parkway. From there, I FINALLY managed to arrive at REI.

It's a good thing that I like the Paradise Valley area.

My primary reason driving along Bell was that I wanted to see what was beyond the intersection of Bell and 43rd Avenues.

The last time I bought a new pair of hiking boots was during the Autumn of 2011. I had recently returned from working six months in Afghanistan and needed a new pair of hiking boots. At the time, I was was living in Reston, VA. The nearest REI located in Fairfax, VA near the Fair Oaks Mall. Since I was wanted to do some hiking in Virginia-Maryland-West Virginia, I bought a pair of Solomon hiking boots for $230.

That was twelve long years ago.

When I moved back to Arizona in November, I took up hiking again. After a couple of hiking trips in the area, the idea occurred to me to buy a new pair of hiking boots. The Solomon hiking boots still worked on hikes to the Thunderbird Conservation Area in Glendale. However, I couldn't let go the idea of buying a new pair of hiking boots.

Anyway, this past December, I noticed that the Zamberlan 1996 VIOZ GTX hiking boots were on sale on REI's webpage. Regularly priced at $350, the hiking boots were on sale for around $230. These hiking boots weren't your typical Merrell hiking boots that would you buy at, say, Dick's Sporting Goods for "day hikes". These Zamberlan hiking boots were designed for extended hiking and backpacking. I had always wanted a pair of hiking boots like the Zamberlan 1996 VIOZ GTX hiking boots. Without driving to REI in Paradise Valley to try on a pair, I bought a pair of the hiking boots at size 10.5 in the grey color.

The hiking boots arrived in the mail two days later.

The first time I wore the Zamberlan hiking boots on the trail was a mixed bag. At the beginning of my hike at Deems Hills in Phoenix, the hiking boots performed remarkably. I felt and hiked like The Terminator. Near the end of my hike, however, my feet felt painful. I couldn't wait to get back to my car, take the hiking boots off, and put on my New Balance running shoes. Little did I know that I would spend the next couple of days recovering from my six mile hike in mountainous desert terrain.

I figured that my new Zamberlan hiking boots just needed to be broken in for my feet.

Subsequent day hikes in Peoria repeated the same pattern. At the beginning of the hike, my feet felt great. After hiking a couple of miles, my feet would begin to ache. I couldn't wait to get back to my car and change shoes.

Two weeks ago, I went hiking in the Phoenix Mountain Preserve. The pattern repeated itself. When my moderate four or five mile hike accidentally turned into a difficult six or seven mile hike, my feet felt as if they were on FIRE by the time I returned to my car. I could barely walk.

A subsequent hike at Papago Park the following week confirmed my hypothesis that my hiking boots were too small and needed to be replaced.

Remembering that REI allowed customers to return purchased items up to one year after purchase, I cleaned off my Zamberlan hiking boots and made the drive to Paradise Valley.

The whole return item procedure at REI was a breeze and without any hassles. Plus, the REI employee that processed my return, Jennifer, was quite helpful. I picked up another pair of Zamberlan 1996 VIOZ GTX hiking boots. This time, I picked up a pair that are size 11W. I even put on the hiking boots and walked around the store for several minutes. Just to be on the safe side, I made a point of walking a couple of miles prior to going to REI.

What a relief!!!

I am planning to go hiking this weekend with my new hiking boots.

We'll see what happens and how my feet will feel after a five or six mile hike.

While at REI, I also picked up the Nano 22 H2O Hydration Pack - Plus Size by Gregory.

Nano 22 H20 Hydration Pack by Gregory

The reason for the purchase?

Well, the Camelbak hydration system that the Army gave me to take to Iraq way back in 2006 has probably neared the end of its usefulness. For the past couple of months, my trusty Camelbak has started to leak through the drinking tube. The leak started to occur when I would use my Camelbak bicycling. The Camelbak would leak all over my right thigh. Recently, the drinking tube started to leak while hiking. In fact, just 10 days ago, my Camelbak leaked all over my map during a map and compass course given by REI down at Papago Park. When I went hiking after the class was over, I noticed that my water didn't last very long.

As a result, it was probably time to buy a new hydration system.

Moreover, I doubt that I could buy replacement parts for my Camelbak hydration system.

Why did I choose the Gregory hydration pack over hydration packs made by Camelbak and Osprey?

I really cannot say. The Gregory hydration system just appealed to me. Granted, Gregory produces more elaborate hydration systems than the Nano 22 H20 Hydration Pack. Just check their webpage. For now, I was happy that the Gregory hydration pack that I chose had a 3-liter bladder and a large pocket for storing my rain jacket, Clif bars, headlamp, first aid kit, cellphone charger, USB cable, etc. Now, I no longer have to use my waist pack and fill up the cargo pockets on my shorts.

Since I recently received a notification from REI that Kayaking 101 class scheduled for Saturday, April 27th, at Lake Pleasant has been cancelled, I guess I am going hiking this Saturday. It's time to try out my new gear.

Starting New Online Cisco Networking Academy Course...

Last night, I started work on the "Network Addressing and Basic Troubleshooting" online course over at the Cisco Networking Academy.


In a previous post, I was somewhat leery about starting the online course. My thinking is/was to drop the online courses over at the Cisco Networking Academy and re-start studying for Cisco's CCNA certification.

The main issue(s) is that the CCNA certification possesses high recognition. It is an IT certifcation that is in high demand by various organizations that use a computer network. Plus, the rewards of having the CCNA certification on your resume and on your LinkedIn profile are very high indeed. The CCNA certification will instantly elevate your job application. Let me put it another way. You shouldn't have any problems finding a good paying IT job once you have the CCNA certification. If you cannot find work with a CCNA certification on your resume, then you might be doing something wrong or you shouldn't be looking for an IT job.

On the downside, studying for the CCNA certification requires a H-U-G-E amount of time and dedication to complete.

On the other hand, the online courses available over at the Cisco Network Academy are supposed to take less time and effort to complete. Plus, you can add the course completion badge to your LinkedIn profile and resume as soon as the course is completed. According to the Cisco Networking Academy, once you complete the four basic networking courses that are available, you are then eligible to take the certification exam for the CCST certification in Networking.

Cisco also has a CCST certification available for cyber security operations. Yes, the CCST certification in cyber security operations is also on my To Do List. Interestingly, some of the networking online courses are pre-requisites for the CCST in cyber security operations.

For now, my goal is to get an entry-level position in either networking or cyber security operations by completing these online courses available from the Cisco Networking Academy.

I really haven't decided on whether to take the CCST certification exam(s).

That said, the CCST certification is meant by Cisco to be an entry-level certification to either the CCNA certification or Cisco's own cyber security certification.

Anyway, instead of dithering, I am plowing forward with the online courses from the Cisco Networking Academy.

After all, the online courses from the Cisco Networking Academy, including Packet Tracer, are FREE.

New Cisco Network Academy Online Course...


This morning, I decided to go ahead and start the next networking class over at the Cisco Netowrking Academy website.

The name of the online course is "Network Addressing and Basic Troubleshooting".


Compared to the previous two courses that I have completed at the Cisco Networking Academy, this course will not take as long to complete all modules and the final exam.

I am also seriously considering re-reading Volume 1 of the CCNA 200-301 Official Cert Guide.

The first couple of chapters cover topics relating to theory, such as the five-layer OSI model, before going in-depth into the Cisco IOS.

In fact, the "Network Addressing and Basic Troubleshooting" online course covers the Physical Layer of the OSI model, including topics such as copper Ethernet cables, wireless, fiber optic cables, and so on.

Heck, I just might go down to my local Home Depot (in Peoria, Surprise, or Phoenix) and purchase some Klein computer networking tools, a length of Ethernet cable, and some RJ-45 cable connectors. It would be a good exercise to try and create my own crossover Ethernet cables.

Another item to consider is to purchase one of those home networking kits for CCNA study that contains a couple of switches, a router, and a rack. However, that's for another post.

Even more fun would be to create my own server. That's a different kettle of fish entirely.

New Cisco Certifications...

Since I moved from Catonsville, MD to Maricopa County, AZ this past November, I have been working on online computer networking courses available over at Cisco Networking Academy.

So far, I have been taking courses for the Cisco Certified Support Technician (CCST) certification in Networking.

There are four online courses for the CCST in Networking:

  • Networking Basics
  • Networking Devices and Initial Configuration
  • Network Addressing and Basic Troubleshooting
  • Network Support and Security

Thus far, I have completed the courses for "Networking Basics" and "Networking Devices and Initial Configuration".




My current goal is to complete the courses for "Network Addressing and Basic Troubleshooting" and "Network Support and Security", so that I can then take the certification exam for CCST in Networking.

This sounds good and all (on paper), but there is a problem.

Prior to taking these online courses, I was attempting to study for Cisco's much in-demand CCNA certification.

I emphasize "attempting" because I was working the 12:30 PM to 9:00 PM shift for my Tier 1 IT help desk position at the Social Security Administration in Woodlawn, MD.

That job was like being on a runaway freight train. Every day was just crisis after crisis after crisis.

Plus, real life also tended to happen.

As a result, my progress with studying for CCNA was slow and meandering. It was quite frustrating.

On the plus side, the Pearson Vue Network Simulator tool was a joy to work with. I learned a lot on how to use Cisco's command line interface to configure switches.

Getting back to the CCST in Networking...

The online courses at the Cisco Networking Academy involve a lot of time and effort to complete.

I am taking exhaustive notes on all of the information presented in each module for each course.

However, I can honestly say that I know more about subjects like Address Resolution Protocol (ARP) and TCP/UDP than I did when I studied for CCNA.

Due to the two online courses that I have completed, I can also say that I am much better at using Packet Tracer than I was when I studied for CCNA.

Here is my main criticism about Cisco Networking Academy: In the time I spent on the "Networking Basics" and "Networking Devices and Initial Configuration" courses, I could have used that time to study for CCNA.

On the other hand, what intrigued me about getting the CCST in Networking certification was that I was looking for a way to get my foot in the door of networking.

Should I continue on and complete the final two courses for the CCST in Networking or should I just re-start studying for CCNA?

That is the question.

Unfortunately, there don't seem to be any easy answers.

It would be interesting to read other people's experiences.

Coming Back to My Blog...

Well, it has been a

L-O-N-G

time since I have posted anything on my blog here at Blogger.

The fact is that I completely forgot about my blog here at Blogger.

The fact is that I got overwhelmed with work and the long list of things that I was doing at the time.

It's par for the course, actually.

I make all sorts of plans on what I want to do. I can come up with a list of goals that I want to achieve.

Those aren't a problem.

Then, I get overwhelmed. I get distracted. Then life happens.

Then, I get bored and/or discouraged because I haven't met any of the goals that I have set for myself.

It happens.

Some people think that I have Adult-ADHD.

It's quite possible and would explain A LOT.

Anyway, so why did I come back to my dormant and forgotten blog here at Blogger?

Well, when I recently went hiking two weeks ago, I took 68 photographs. While going through the photos on my Dell laptop, I got overwhelmed with trying to decide what photos I was going to post to Facebook for people to see.

I suppose that I could have just posted 12 random photos from the 68 photos to Facebook and then moved on to something else.

For me, it's not that easy. When I make a post to Facebook, I make a post. In fact, it's more than a post. It's probably closer to an essay.

After considering opening an account at Flickr, I remembered about my blog here at Blogger.

I can make a long post about going on a hike, add a map, and upload as many photos as I want.

I can do the same thing when I go for a bike ride.

Plus, I can then write posts about other subjects and things that I am doing.

Believe me, there is A LOT that I want to do and achieve.

Plus, I get to rediscover how to write in HTML. ;-)


Stay tuned for updates.
