Lenovo PC Turns on Unexpectedly

For the past few nights my Lenovo desktop (B40-30) has been turning itself on automatically in the middle of the night. At first I thought perhaps the power button was depressed by a book next to the computer. I checked and that wasn’t the case. After searching google I’ve found that this is a common problem experienced in Windows 10.

It turns out my wifi driver was set to automatically turn-on my desktop if prompted by wifi. This problem was solved by turning off the option to allow my desktop to be waked by the wifi network, which was checked.

 

 

A New Suitcase

The likelihood of traveling frequently by plane and not having luggage damaged by mishandling is very low, making it important to invest in well-designed luggage backed by a good warranty policy. Briggs and Riley manufactured luggage fits both of these criteria, which I was introduced to by a sales associate while visiting Harrods in London. I purchased the Baseline, U122CX a two-wheel carry on meeting the dimensional requirements for most airlines I fly on. The four-wheel bag might have been more maneuverable but I felt the space trade-off made for the four-wheel bag was too great.

The bag is extremely well-constructed with a garment system built-in to keep a suit from being wrinkled, a clever expansion system that compresses the bag by 25%, and parts that can be easily replaced. I’m very happy with my purchase and plan to buy more Briggs and Riley products in the future.

 

We need more trains

The Amtrak tragedy is unfortunate and we shouldn’t rush to conclusions on why the accident occurred until the investigation is completed by the NTSB. I enjoy traveling on trains, I’ve used Amtrak Acela service, Eurostar, French TGV, Taiwan High Speed Rail, and Italian High Speed Rail. Train service needs to be expanded and faster, routes between places like Boston, MA and Burlington, VT take an entire workday and this is unacceptable. Fast train service will provide more flexibility by enabling more weekend trips and reducing carbon emissions.  Improving our national rail infrastructure will require investment by the government and/or private entities.

Part 1: Understanding the Difference between Complex and Complicated Systems

Last March I was driving across the San Francisco-Oakland Bay Bridge into one of the most dynamic cities in the world. Sitting next to my good friend and former classmate, I commented what a complex design problem the bridge had posed, with two major crossings and requirements to withstand earthquakes and carry over 240,000 vehicles per day. Being an engineer, she pointed out that the bridge was not a complex bridge at all.  While it was undoubtedly difficult to build, it was not complex. Rather, it was a complicated structure.  The engineers were experts; using their professional knowledge on build bridging and previously documented learning, they were able to apply existing design principles to build an amazing structure that has stood since 1936.

Distinguishing between a complicated and complex problem or system is not an easy task for most. As Sargut and McGrath argue, if individuals in a business are unable to differentiate between these two distinct terms, it will be very expensive for a business in the long run. It’s necessary the distinction be made because how you approach a problem changes drastically depending on the type of system. What is the difference between complicated and complex? Simply put, a complicated system is predictable if it follows patterns that can be observed. This leads to a system that is definable such that past behavior predicts future behavior.

As my friend put it, intricate is probably the best word to describe a complex system. Complex systems are unpredictable and sometimes undefinable. In a complex system the initial conditions can lead to different outcomes. The question then becomes how can we define a complex system.  The three most important characteristics of a complex system are multiplicity, interdependence and diversity.  Multiplicity refers to the number of potentially interacting entities, interdependence to how connected these elements are, and diversity to how heterogeneous each element is.

Manufacturing is extremely complex, with a lot of interdependent pieces.  If we ignore those pieces our ability to solve problems falls apart. At times we are faced with problems that transcend a particular part of the process on which we are focused. If the scope of the problem is not realized, our ability to solve it is severely impaired because we may be searching for solution that address symptoms and not root causes.

How do you solve complex problems in contrast to their complicated counterparts?

Complicated problems have blueprints; you can draw on expert knowledge and previous experience to create a solution. You can perhaps consider these types of problems the ones where you can open a textbook and find the answer, or in the case of a business, consult an expert on the subject.

Complex problems are not so simple.  There is no blueprint, no readily modifiable solution. The solution is determined on a case by case basis. When it comes to complex systems, no two situations are alike. Forcing a pre-made solution to a complex problem can bring disastrous consequences, since using the wrong metrics on a complex system can lead to inefficiencies and a false sense of security which I will discuss in another section.

Martin Luther King and the March on Washington

MLKMarch

The Rev. Martin Luther king was one of the most famous Civil Rights Activists of the 20th century. Born in Atlanta, Georgia, King worked tireless to organize nonviolent civil disobedience to promote the advancement of civil rights. He is most known for helping organize the 1963 March on Washington, one of the largest human rights rallies in United States history. There King went into American history as he delivered his “I Have a Dream” speech urging for integration and equal rights for African-Americans. August 8, 1963 was a watershed moment in the civil rights movement bringing more support to end discriminatory laws. Many credit the March on Washington with getting the Civil Rights Act of 1964 and the Voting Rights Act of 1965 passed. The Civil Rights Act outlawed discrimination against racial, religious minorities and women signed into law by Lyndon B. Johnson. The subsequent Voting Rights Act prohibited having any qualifications to vote based on race or color.

I think what’s hard to grasp is 50 years ago discrimination would have been legal. It’s hard to imagine that 50 plus years ago, I would have to drink out of separate water fountain from my non-black friends and I wouldn’t be allowed to eat in certain places. It truly is amazing how far we’ve come in this period from segregation to the election of the first black president. Today is indeed a special day, 50 year ago it marked the beginning of a dream that was finally realized.
