The Best designed computer system Architecture

CPUComputer Architecture  has a great effect on security and performance. The key components of good Computer Architecture and performance are as follows:

• Central Processing Unit (CPU) – gets instructions from memory and executes them.  Some high end CPU’s are:

  1. AMD Ryzen Threadripper 2950X @  3.5 GHz 16 core $654
  2. Intel Core i9-9900X @ 3.50GHz  3.5 GHz  10 cores (2 logical cores per physical) $899
  3. Intel Core i7-9800X @ 3.80GHz 8 cores (2 logical cores per physical) $899

• Registers – points to memory locations that contain next set of instructions to execute.

• Arithmetic logic unit (A.L.U) does the actual execution of instructions.

• Control unit manages and synchronizes system while application code and Operating System instructions are executed.

• General Register – hold variables and temporary results.

• Program status word holds conditional bit, should CPU be working in user mode (problem state) or privileged mode (kernel / supervisor mode).

• To access data, CPU sends fetch request on address bus.

Random Access Memory – temporary storage facility where data & program instructions can be temporarily held and altered. Volatile means that loss of power results in  loss of data.

Hardware segmentation – memory is separated physically instead of just logically. This help protect higher level process’s memory space.

Cache memory- high speed writing and reading activities.

Motherboards have different types of cache.

• Level 1 – fastest

• Level 2 – 2nd fastest

• Level 3  – 3rd fastest

L1 & L2 is typically built into controllers and processors.

Having a great understand of all the facets that go into computer Architecture allows you to get the best performing system while providing excellent security.

Training and continuing education with Coursera

Training and career development are a crucial component to improving yourself and becoming more successful. During my studies, I have completed and extensive review of available training platforms. I have some very useful and valuable information.

I started reviewing some additional training sponsored by Google through Coursera. The first program was Google IT support professional certificate. Coursera gives users a 7 day free trail with full access to every course in your specialization. I enrolled in the IT support professional certificate specialization and I liked the class very much.

The IT support class was a combination of video lectures, exercises, and module quizzes. I found the material was interesting and informative. The program covered some very interesting material: digital logic, computer architecture, operating systems, networking, software, troubleshooting, and customer care. For some of the hands on exercises, we used Google cloud services to spin using up servers and associated services. I really liked using Google cloud services. The monthly cost for the program was $49 per month. I completed the course and received the following course certificate.

The next program I worked on was System Administration and Information Technology Infrastructure Services. Since this was they type of work I have done for most of my career, I was very interested in this topic. The work I do as a system administration, and the topics covered were: cloud services, server maintenance, infrastructure services, hardware provisioning, system maintenance, virtualization, remote access, SSH, Network services, Software services, File and Print services, Platform services, Directory Services, and Data recovery & Back Ups. The monthly cost for this program was $49 per month. The course material keep me engaged and working hard to complete each module. I felt the cost was well worth the price. I completed the course and received the following course certificate.

System Administrator IT infrastructure

I really enjoyed the first two class, so I continue on my Information Technology specialist track. The next class in the program was computer networking. Designing and building networks is a passion on mine, so learning more about networks was exciting. The class covered the following topics: TCP/IP 5 layer network model, OSI network model, Networking devices, Network Setup, physical layer, Data link layer, Network layer, Sub-netting, Routing, Transport layer, Firewalls, Application layer, Network services, Virtual Private Networks, Wide area network, wireless, Dynamic Name service, Cloud networks, and troubleshooting.

110 Grill review

We went out on the town and had dinner at the 110 Grill in Braintree Ma. There was a Good size crowd, and nice atmosphere. The Bruins are on TV, game 2 of the NHL playoffs. For Bruins fans, it was kind of a must win.  I ordered an Arnold Palmer, in honor of the masters golf tournament and the king of golf Anrnold Parmer. Pretty tasty!

We were feeling good and the service was excellent, and the waitress is cute! Not a bad start to the evening.

We got a table pretty quick and we had a nice view of the Bruins game.

We order an appetizer Chorizo Totchos, the food came out pretty fast and it looked pretty good!

We received our appetizer which looks good.  The only down side was,  no silverware to eat it.  We got some from a passing waiter and off we went.  The Appetizer “Chorizo Totchos” is very good. The main ingredient,  (potatoes) was cooked to perfection. The taste was delicious with chives and sour cream. There was a hint of chili sauce and salsa. I would say a great appetizer, definitely very pleased! The portion of the appetizer was great, plenty of meat and potato’s to get you started! So far I am impressed!

For my entrée, I got Shrimp & Clam linguini. The sauce (butter & Lemmon) was hot and tasty, The Shrimp and clams where cooked well and the meal felt healthy and some what light. The toasted bread was a nice touch and I enjoyed my meal while watching the Bruins. An added bonus was the Bruins were leading the game 2 (2 – 0).

The burger and onion ring got a 10 out of 10 stars. (**********). The Claim & Shrimp linguini got an 8.5 out of 10 start. (*********). The meal did not blow me away, but it was really good. I would recommend 110 grill as a place to put into your dinning rotation! We had a good time and really liked the 110 grill!

Boston Red Sox 2018

World Champions

The Red Sox are world champions.  Back in April, I knew there were good, a playoff team for sure.  As the season progressed, it looked like an American league East division title and home field advantage. This was an awesome development as my son works at Fenway.

Clearly the Red Sox are good, but their bullpen is not dominant and has failed to hold leads in many games.  Even though this was a major flaw, they still had the best record in baseball.  I though there was no way they would beat Houston in a series. Houston definitely had the better pitching and bullpen.

In the ALCS, the Red Sox lost game one and are down 4 – 2 in game 2.  Then Jackie Bradley Jr (JBJ) hits a double scoring 3 runs and Mookie provides the insurance runs to tie the series at 1.

In the decisive game 3, JBJ comes through again with a grand slam to close the door on the Astros.  The emergence of two key additions, Steve Pierce (key homers) and Nathan Eovaldi (throwing smoke) propels Boston towards the world series.  The Red Sox are victorious an gain a 2 -1 series lead.

Heading into game 4, the Red Sox have a chance to go up 3 -1. If the Red Sox  have a 3 – 1 series lead, it is pretty much over.  Game 4 was a very close game and key for both teams. In a key moment, Houston’s Altuve hits a deep shot to right and Mookie drifts back and perfectly times his leap to make a great catch.  A Houston fan appears to touches the ball preventing Mookie from making the catch.  The key question was, did the fan interfere with the catch? Umpire Joe West makes arguably the greatest call in ALCS history and calls him out! There was fan interference resulting in the key out.

In the late inning JBJ hits another key home run to give the Red Sox some breathing room.  In the bottom on the 9th and the game slipping a way from closer Kimbrell, another key moment is about to happen.

The Astros have loaded the bases against Kimbrell. The Astros slugger Alex Bregman hits a line drive to left. This appears to be the game winning hit. Red Sox out fielder  Andrew Benintendi starts to close on the ball. At the very last moment he dives and make a miraculous catch, saving the game!

In un-believable fashion, the Red Sox win the game. With a great performance from the Boston out field, Boston solidifies the best out field in major league baseball.  Not to mention, the Outfield has the best choregraphed dance moves ever seen on a baseball field. Check out YouTube, pretty cool

In the clinching ALCS David Price throws a gem, Martinez and Devers hit key home runs, as the Red Sox advance to the world series.

The Red Sox go into to defeat the Los Angeles Dodgers  4 -1. David Pierce becomes World Series MVP and Boston has another world championship in baseball.

CISSP security professional

Security professional

I have began the process of gaining CISSP security professional certification.  The CISSP certification holds a lot of value in todays job market. As security threats, attacks escalate, being able to mitigate these risks is very valuable.

The black market or hacking community is consistently developing tools to penetrate vulnerable networks. Many of these tools are designed to install back door access to corporate networks. Once these back door tools are installed, the hackers has gained access to valuable data. An example of valuable data is credit card numbers, social security numbers, and corporate intellectual property.

Much of the illegal hacking goes undetected or cyber criminals go unpunished. The hackers use many zombie systems to carry out various attacks on institutions. Since a zombie system was used, it is very difficult to track down the hackers. This has become a huge problems for corporations and subsequently law enforcement. Improve security is one mechanism to migrate the risk associated with hacking. I will be reviewing tools available to help protect yourself and your company. Subscribe to stay up to date!

Football in America, what the future holds

The sport of American football is a collusion sport loved by many. Over the years, injuries such as concussions has given the game a bad name! For many of us: players, officials, and coaches, the game maybe in trouble.

For the many players, the risk of playing may out weight the benefits. As the numbers of people playing has dwindled, football organizations have taken many steps to make the game safer. Rules changes now penalize players who make hits that can lead to injury. Illegal hits to the head can result in disqualification and/or rejection from the game.

As a result of the rules changes, the players and coaches are working to play the game in a safer manner. Football is inherently dangerous as are many things in life. I believe football can be played in a manner where the risk of injury is significantly reduced. As football officials, we work hard to make the game safe for the players, and more enjoyable for the fans.

At the college and NFL level, the stakes are much higher. At these levels, millions of dollars are at stake!

In order for football to survive, the game must change and adapt. We all must work hard to make all things safer. We who love the game, and we are striving to make the game better. We are working to save football for future generations! Thanks and have a goo season.

Key West – Bridge to paradise

Travel and review of my trip to Key West.

The journey to Key West

In 2017, I completed  one of my top bucket list items with a trip to Key West. As we embarked on our trip to Key West, we took a Lyft Luxury to Braintree Ma Airport shuttle on the way to Logan International. We were running late  and a bit rushed  heading to the airport.   We checked in and then we had to be processed through Airport security. The One ticket with precheck did not help the situation. Pre-check allows passengers to bypass Homeland security. Luckily we made it to our gate as the plane was boarding. Low and behold, I had a problem, my belt was left at the security checkpoint. I did my best OJ  impersonation and sprinted to get my belt. I made it back as our JetBlue  plane was last  call boarding.

A couple of hours later, we landed at Miami international Airport. We got our bags and headed to get our rental car. We rented a car from Hertz and it took an ungodly amount of time to get the rental. Recommendation, If you can afford it, I would recommend getting a Ford Mustang Convertible. During the wait, I picked a place on South beach to have brunch. Shortly we were off to South Beach.

We arrived at the Front Porch Cafe on Ocean Blvd. The food, service, and atmosphere were excellent. I would rate experience 5 stars and highly recommend it. It was a great way to start the day.

After brunch, we explored Ocean Blvd and headed to the beach. For years I have wanted to see South beach, we were finally here and it was awesome! The palm trees, architecture, culture were all wonderful to see.

After spending an hour at the beautiful beach, we sat and took it all in.  The ocean water was so increadabily warm and the sand was baking hot.   After our stroll on the beach, we picked up some Cuban cigars and head to Key West.


After spending the day at South Beach, I definitely want to own a condo in Miami.  Follow my journey to finding the perfect real estate investment in Miami.
