Superintelligence Paths, Dangers and Strategies – Book

Superintelligence: Paths, Dangers, Strategies by Nick ...During the past few months it has been somewhat hectic for me. I used to write and post on my blog more often. Lately I have set aside only weekend mornings to learn new things and refresh (courses), experiment, and write posts.

A few weeks ago I finished reading Superintelligence Paths, Dangers and Strategies by Nick Bostrom. If I am not mistaken the book made it to the NYT bestseller list during 2014. A teammate at work mentioned the book so I decided to get a copy and read it. Continue reading “Superintelligence Paths, Dangers and Strategies – Book”

Algorithms and Data Structures for Massive Datasets

Algorithms and Data Structures for Massive Data Sets

I just finished reading and to some extent experimenting with most of the concepts presented in the book by Dzejla Medjedovic, Emin Tahirovic with illustrations by Ines Dedovic © 2022 Manning Publications ISBN: 9781617298035.

I signed up on Amazon to get the book as soon as it was released. As with most work, the first edition has a few typos. In addition, the book could have had more examples. It seems that as the book progresses the number of examples diminishes. Overall a nice book! Continue reading “Algorithms and Data Structures for Massive Datasets”

Deep Work

I typically get a couple dozen technical books for each non technical. I purchased via Amazon “Deep Work” by Cal Newport. I saw it mention while reading an article in Medium. It took me less than a week to read the book. The subject is very well known to me. Will explain why it is the case in the following paragraphs.

I was born in Lima, Peru. My parents left Europe in the 1930s in search of a better life. I had three siblings. One of the twins graduated from college as an international attorney and passed away months after. My other two sisters are physicians. One continued her studies in the USA and Europe. Today she is a professor at an Ivy League school spending time in a lab in China at a well know university. I came to this country over 40 years ago with a scholarship to attend an Ivy League school in New York.

Missing Book – Amazon.com

I have been purchasing items from Amazon through the years. With two exceptions the experience so far has been very positive.

Years ago, my wife and I purchased via Amazon a Le Creuset pot for our son. The pot was made of ceramic. The pot arrived at our son’s residence chipped. When we learned about the issue, I checked on the Amazon web site and filled the form to return the item and get a reimbursement. We decided that a ceramic pot might not be a long lasting item. So far all was fine. Our daughter in law was going to return the item. Apparently she lost the slip and we had no way to prove that we had returned it to Amazon. We were not reimbursed for the purchase. Like I said, the issue was on our court. Continue reading “Missing Book – Amazon.com”

Building Microservices – Peek

In general I tend to read only one book at a time. I fully understand that when you are in K-12 and later in college, you are obliged to read books for the different simultaneous courses that you are taking. Once people are done with formal training, most of us never read a book again. That is a shame. It seems that the rush in life does not give us time to read. When tired we just sit and want to be entertained by whatever is being showed on TV or at a theater. My wife and I prefer to sit down and chat. When we are not working and are not together, we both read books. About a year ago we stopped watching TV so we returned the cable boxes. Today we only have Internet access. That way, when someone recommends a movie, we are able to get it on-line. All our TV sets at home are equipped with Chromecast which makes it so easy to watch from pictures to movies.

Geographic Information Systems (GIS)

A few weeks ago I was looking in Amazon for books that dealt with photogrammetry. During my search some associated books showed up. After taking a look at the table of content on two that called my attention, I decided to go with both, not for depth in the subject, but to get a broad look at GIS.

One of the books I selected is titled Geographic Information Systems – An Introduction by Tor Bernhardsen published by Wiley in 2002. In chapter 10 Data Collection II, section 10.3 Photogrammetry Mapping provides a simple and high level description of the basics in the subject. To be honest, you can get a more up to date and extensive description in Wikipedia. Continue reading “Geographic Information Systems (GIS)”

Beyond Fear

Hope your Memorial Day weekend 2017 is going well. Yesterday afternoon my wife and I stopped by her brother’s place to prepare, cook and then consume a late lunch. Earlier in the day my wife chopped some onions and peppers, cut some chicken thighs and pork shoulder, I pulled from the freezer some bags of shell fish (OK sue me, we eat pork and shell fish) and an assortment of spices (including saffron). We put in the trunk of the car a box holding the ingredients and our 24” paella pan. Continue reading “Beyond Fear”

Jiro Dreams of Sushi

Last Friday GC (software engineer) on his way to work was listening to a podcast. During the program a video “Jiro Dreams of Sushi” was recommended for the audience. When GC arrived at work he sent me an email suggesting the documentary. Continue reading “Jiro Dreams of Sushi”

Bag Algorithm

bag_queue_stackHave to admit it, after a few (will not say how many) years studying Computer Science, architecting and developing systems in multiple programming languages and platforms I had missed the Bag algorithm :o( Gladly I am spending time reading and performing several (do not have time to work on all) exercises and examples in the Algorithms fourth edition book by Robert Sedgewick and Kevin Wayne.

The Bag algorithm is used to implement an object that stores in no particular order items added to it. There is an Application Programming Interface (API) to get the size of the bag and to determine if it is empty. If an Iterator is implemented, then a client is able to iterate in no particular order through the items in a bag. Continue reading “Bag Algorithm”

Generics Implementation

algorithms_fourth_edition_back_coverThis blog entry is based on the example on page 141 of Algorithms fourth edition by Robert Sedgewick and Kevin Wayne. I am reading the book as a refresher and learning experience on computer algorithms. Initially what called my attention was the statement that it contains 50 algorithms that every programmer should know. I want to make sure I have a good handle on those algorithms. After reading the first few chapters which have not cover the algorithms yet, I feel that the way the ground work is presented is very educational, direct to the point and simple to follow. I always like simplicity in code and documentation. Elegant code is very hard to find and write. This book seems that it should help readers achieve such goal.
