I
n 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)”
Dedication, Drive, Excellence and Passion
For the past few years my wife and I decided to stop wasting time watching TV. It seems like the content of programs is quite weak and depending on the time the show is aired, the number of commercials increases to the point that a half hour program is aired in one hour. We used to make fun of commercials from cable networks that boasted the feature of being able to watch a program while simultaneously recording other three shows. Continue reading “Dedication, Drive, Excellence and Passion”
While Switching to C++ (edited)
**** UPDATED POST ****
Yesterday I was under the impression that all was well with the updates on my Windows 10 development computer. To learn more about it take a look at the section labeled ORIGINAL POST in this entry. Continue reading “While Switching to C++ (edited)”
Windows 10 Update Not Completing
Do not recall exactly when it happened last time, but earlier this year my development computer running Windows 10 received a Windows update. The update was applied (as far as I could tell). From then on, when I would shutdown or restart my computer, I was asked to update and restart or update and shutdown. Something was not right. I do not recall what I did to get out of such state last time, but it worked. Continue reading “Windows 10 Update Not Completing”
Container ship collides with USS Fitzgerald
Over the weekend a container cargo ship sailing near Japan collided with the USS Fitzgerald causing loss of life (reportedly seven sailors die in the event). My sincere condolences to the family, relatives and friends affected. Over the weekend I read a few articles regarding this incident. For the reasons I am going to cover in this post, the news called my attention and motivated me to write this entry. Continue reading “Container ship collides with USS Fitzgerald”
Log File – Next Step
To recap on the log file sub system, the initial software was able to log from any thread in any process in a single computer messages which included values of variables. Following is a snippet from a log file: Continue reading “Log File – Next Step”
Settings – Part I
Thinking of ways to architect / design software is a good way to improve your software skills. In this case I will try to come up with an initial design to implement a set of settings. The approach will look at the server and the client software. The idea is that different applications / sub systems would use a single application to manage their settings. Continue reading “Settings – Part I”
Log Files
About a couple decades ago I came up with the idea for a storage server. This occurred while experimenting and working with a Hierarchical Storage Manager (HSM) product that worked on a Sun Solaris system and used tapes in an automated library to manage the contents of the files. At that time the idea of a Content Addressable Storage (CAS) was several years away. Continue reading “Log Files”
Swap Values
While programming in most (never say all) programming languages and platforms one often runs into the need to swap the values of two variables. The following code in Java illustrates a first attempt to swap two integers: Continue reading “Swap Values”
