I am always trying to read and practice with topics / subjects that I feel learning or call my attention. I am currently taking some specialization courses on Coursera. You can never give up and stop learning. In this post I will describe how I installed Hadoop and the issues I encountered. Continue reading “Issues while Installing Hadoop on Windows”
My wife and I are going to attend a wedding on July 5th. I am going to wear black dress shoes. A week or so ago while at Nordstrom’s at the MOA I was going to get a pair of shoes for the occasion. My wife mentioned that I have a pair of never worn black shoes still in their box. This morning, my wife gave me the shoes. I decided to wear them at home for a few days in order to make them mold to my feet. Seems like most of the times I wear new shoes I get blisters on my feet. I am the type of person that wears thick socks even when wearing sandals. Will see how things went after the wedding. Continue reading “Castor Framework”
Kubernetes, it appears to me to be a funny sounding word that could be uttered by an actor in a science fiction movie. If interested in the actual origin of the word, take a look at the following Kubernetes link in Wikipedia.
I am more interested in what it does than how the word came to be (even though I did read the entire Wikipedia article). In the book Production-Ready Microservices by Susan J. Fowler; published by O’Reilly (which I purchased from Amazon and read), a nice and simple diagram is used to describe the four-layer model of the microservice ecosystem. Continue reading “Kubernetes”
I apologize for not being consistent on my posts. Technology and projects change quite rapidly so what might be of interest today might not be in a few weeks. In the past few weeks a decision was made to use the Windows platform to develop the next generation of a storage server. The storage server will be developed using ASP.NET Core. Due to that fact, I have been experimenting with the ASP.NET Core SDK and runtime. Yes, the last statement is not a typo. The ASP.NET Core has a SDK using its own version number and a runtime using a different version number. Continue reading “ASP.NET Core”
A couple weeks ago I was reading and experimenting with OAuth 2.0. I have been learning (it is a never ending task) and using encryption for at least a couple decades. Have developed some hashing algorithms to hash software licenses, but have never attempted to develop a full encryption algorithm. Continue reading “Asymmetric and Symmetric Encryption”
It just happens that I work remotely. Have been doing so for a few years. Working remotely has a few advantages and disadvantages. As we know in software engineering there is no silver bullet. One of the disadvantages is the quality and features of collaboration tools (hardware and software). Continue reading “Jamboard or Surface Hub?”
OpenID Connect 1.0 is a simple identity layer on top of the OAuth 2.0 protocol. It allows Clients to verify the identity of the End-User based on the authentication performed by an Authorization Server, as well as to obtain basic profile information about the End-User in an interoperable and REST-like manner.
A regular expression is a sequence of characters that define a search pattern. Usually this pattern is then used by string searching algorithms for “find” / “match” or “find and replace” operations on strings. Continue reading “Regular Expressions”
As we all know change is always confronting us. A couple years ago I decided to put a lot more emphasis on polishing on my Java by reading, learning and refreshing concepts. I will continue to do so but will relegate it to a second plane. For the next few months I will put emphasis on C++. Continue reading “More Emphasis on C++”
Yesterday afternoon a software developer and I were talking about some issues that came up earlier yesterday morning as a result of some updates done by a web hosting company where his software is deployed. By the time we were chatting, the hosting company had backed out from the update and he had addressed the side effects. All was back to normal. What called my attention was a comment he made regarding cURL. For some reason the update had affected the operation of cURL. Apparently his software is heavily dependent on cURL.
