UPDATE – This post has been updated.
A lot of good things are happening in my work life. I will continue to comment in future posts.
Today I discussed an idea regarding a new service which will extract data from a huge set of files and will be able to allow access to users. Sorry I will not be able to comment much more on this. I have committed to have a first pass of the architecture and high level design documents first thing Monday morning. Continue reading “Prefix Sum Algorithm”
Yesterday my wife had an appointment at the hair salon. The gal that cut her hair commented that there were more people than usual complaining of seasonal allergies; some of them have never before experienced symptoms. My wife and I have some light allergies every season. Some days this year we have experienced strong symptoms. Hopefully things will get better soon.
Last evening in the local news, it was mentioned that due to the amount of water due to rain and melted snow, farmers are a couple weeks behind planting their crops. Having grains and vegetables is more important than experiencing allergy symptoms. Hopefully all will turn out well as the season progresses. The forecast for today calls for strong rain starting around mid morning and ending early tomorrow. Most of the rivers in this area are at or above normal flood levels. Hope the forecast falls short in moisture.
This week I had the opportunity to talk with a fellow software developer. We briefly discussed the approach of traversing a data structure using loops and recursion. It seems that if the number of objects is relatively small, recursion is elegant approach. That said, for large number of objects, recursion may fail due to execution stack limitations.

It is a beautiful day in the Twin Cities of Minneapolis and St. Paul. Currently it is sunny and the forecast call for highs in the lower 60s. My wife and I are planning on walking 5 miles after work.
The topic for this post is computing Pi. Unless you are working on some specific mathematical issue that requires an extreme precision, you would not attempt to generate Pi or care about how it is generated. You would use the value (typically a constant) returned by the mathematical library in your favorite programming language. Continue reading “Calculate Pi”
A day or so ago I read a post on the Financial Times titled “How the Modern Office is Killing Our Creativity”. This is nothing new but seems that most people do not wish to understand the consequences and apply changes to improve. This specially holds for the CEO down to the project managers.
Since I can remember, I have always tried to set a reminder of what I need to achieve in a specified time period. In some cases I write down the set of tasks. In others I just repeat a set of memorized steps. One way or the other, if possible I perform the tasks in solitude. Of course there are some tasks that need to be performed with others (e.g., consultation regarding an issue, ideas if I get stuck, help team members when they need it). Continue reading “Repeated String”
This morning I read the article Turing Award Won by 3 Pioneers in Artificial Intelligence by Cade Metz of the New York Times. The recipients are Yann LeCun, Geoffrey Hinton and Yoshua Bengio. Continue reading “Covariant Return Types”
I always like to spend some time reviewing and learning new stuff before starting a project or task. The amount of time depends on the urgency of the task. In this case I went over chapter 2 of RESTful Web APIs by Leonard Richardson and Mike Amundsen.
As I have mentioned several times, I like to research a think about the task, implement a Minimum Viable Product (MVP) and with the remaining time enhance the software until the scheduled time runs out. Based on my experience, this approach is welcomed by most customers and development teams. When I say research and think, depending on the level and type of the task (e.g., architecting, designing, implementing), such activities may take from an hour or so to several days or weeks. The time is greatly reduced when you constantly read and experiment and when the task is implementation (i.e., generating and testing code). Continue reading “A Simple API”
This morning after waking up I read Why I Write a Data Science Blog by Rebecca Vickery. The subject of the post is to summarize the benefits that writing a blog, in her case regarding Data Science, provides her with benefits that help her improve towards her goals, and helps others starting a Data Science career with topics and situations that they might / will encounter at work.
I agree with her comments but would like to add that the idea of explaining some topic on writing is a great technique and applies to any type of subject. You do not know what you cannot explain. It is a simple as that. That is the reason I spend a couple hours every day reading, experimenting and then writing about what I have learned. I have tried to apply several of Richard Feynman techniques to my daily life. Hope they are working :o) Continue reading “Java Visitor Pattern”
It is a nice sunny day, at least when I was having breakfast earlier this morning, in the Twin Cities of Minneapolis and St. Paul. Better yet, it is Friday!!!
Spoke with one of my sons. He and his family had scheduled a holiday and were on the road. When they moved, they build a home. Some years went by and last fall they decided to buy a new one that they liked. Shortly after they moved and put their first home on the market. A few months went by and finally they closed on it yesterday. I am very glad for them. Having two mortgages is not convenient at all. Continue reading “Tag Content Extractor”
There was a full moon this morning providing some light before the sun came up. That was nice.
This week I have been taking care of some items that I could not during the past two. My wife and I were able to renew our TSA Pre Checked status for another five years. Was not sure why we had to answer the same questions we did five years ago, and get fingerprinted again. As far as I understand, fingerprints do not change over time. If they would, they would be totally useless. I do not recall if last time we had to present our passports or not. We did have to get our pictures taken. I do agree that the look of people may change in five years. The renewal will kick in before our current one expires. Continue reading “Java SHA-256”
