It is Saturday morning. Last week my wife was going to have over two of his brothers and spouses but she was not feeling well so lunch was postponed for today. After breakfast I made the dough for the spinach scacciata. It is resting in a bowl. After my second and last 2-hour block I will check out the dough.
We are missing fresh mushrooms for the chicken Marsala. My wife and I will be heading out to Trader Joe’s to pick up some last minute items we need for lunch and the upcoming week. Continue reading “Threads and Templates C++”
Good morning. It is Monday January 06, 2020. Last year’s holiday season was rather long. Christmas fell on Wednesday so most companies gave Tuesday as a holiday. On the following week, most companies do not give New Years Eve day as a holiday but most people take it as a personal holiday or vacation day. I work every day (included weekends and holidays). Granted that on weekends and holidays I only sit in front of my computer for only two 2-hour blocks. Continue reading “3D Surface Area”
It is Saturday morning and I am in my second block of the day. I typically do a couple 2-hour blocks on weekend days. As usual I got up at 05:00 AM and got breakfast ready. During breakfast my wife mentioned that she was not feeling well. Apparently she caught a cold or flu.
We had invited for lunch a couple of her brothers and spouses. One of her brother’s birthday was yesterday. We decided to change the menu and postpone lunch with family for next Saturday. We had planned a couple of Italian dishes and I was already savoring them. We both enjoy cooking but decided on a single simpler course for lunch. Continue reading “The Grid Search”
I was going to have a different introduction (the regular chit chat) to this post, but based on the article “Malevolent Machine Learning” by Chris Edwards on Communications of the ACM 12/2019 Volume 62 Number 12 I changed my mind. Allow me to explain.
A couple years ago I took a few courses from Coursera. The general topic was big data and machine learning. The course of interest is “Neural Networks and Deep Learning” by Andrew Ng deeplearning.ai. It was very interesting class and I highly recommend it.
I tried locating my notes on those courses, but not sure what I did with them. Found my notes. I hoped to have stored the transcriptions to verify what I recall about a specific class. I do not have the transcriptions Continue reading “Bigger is Greater”
I am moving along with a project at work. I have completed the first pass. I am now optimizing the code and testing the system as a whole. As soon as I am done will move to replacing a component with a machine learning (ML) model. I am planning on developing the model using Azure. I would like to see if it is better that using OCR (Optical Character Recognition). Will let you know the results later this month.
I decided to give a try to the HackerRank Matrix Layer Rotation challenge. The challenge is rated HARD and worth 80 points. If interested take a look at the requirements. If interested you can read about how I addressed the problem in this post. Continue reading “Matrix Layer Rotation”
Usually my youngest son calls on his way to work. Is almost 10:00 AM and have not heard from him. I work from home so I am able to receive his calls pretty much any time. I do not like to call him because he works out in the mornings and has to go home, get ready and drive to work. His time varies from day to day. We have this unspoken arrangement that if he does not have a chance to call we will do so the next day.
The arrangement is exactly the opposite on weekends. I tend to call him as soon as my wife and I head out for the first activity of the day. Typically is on our way to or from shopping for groceries or running any other morning errand. Continue reading “Missing Two”
UPDATE – The format for the code for the class TrieNode has been addressed. Sorry for the inconvenience.
It is Friday and my youngest and family will be arriving this afternoon for a weekend long visit. My wife and I are getting ready for their arrival later today. We all enjoy good food so we have an extensive menu planned which includes fugazza, pasta carbonara with lots of pancetta, beef roast with a homemade tomato sauce, limoncello cake and different alcoholic and non-alcoholic beverages.
Let’s get to the main subject of this post. I tackled problem 17.13 from the Cracking the Coding Interview book. The problem is name Re-Space. Continue reading “Re-Space”
Currently we live in a world of deception. The overflow of data that we are exposed to every day via news channels, companies and social media streams does not allow us to easily distinguish what is true, what is somewhat true and what are just plain lies.
I am not a political fanatic. Last week president Trump paid a visit to the Twin Cities of Minneapolis and St. Paul. He had a presentation at Target Center in downtown. My only thoughts were not to be in or around that area the day of the event. What was interesting is that some Tweets showed pictures of the event before it started while people were starting to arrive. The Tweets stated that very few people attended the event. This is a premeditated lie. I happen to know a couple people who attended the event and had pictures and videos. Target Center was packed. Continue reading “Baby Names”
This past week my wife, our granddaughters and I returned from a holiday trip to Europe. We visited several cities in Italy, Belgium and Amsterdam. We flew commercial airlines to move between large cities. This made me think of airplane routes and filling up the tanks with fuel. For efficiency reasons airplanes do not get refueled on each stop if it can be avoided. Depending on the part of the world you travel to, airplanes have minimum amounts of fuel they must have on board when they takeoff. The amount depends on the distance to the next stop. I know a few things about the subject because I flew for fun private planes for a few years. For personal reasons (wife and family) I decided to stop. Continue reading “Plane Routes”
It is a gloomy Tuesday in the Twin Cities of Minneapolis and St. Paul. It rained last night. It is quite damp. It is a typical fall day in this part of the country. The only difference is that in the past two years the lawns are green instead of being brown. I do not know for sure the cause for the climate change which is a very controversial topic, but for sure something is changing.
I am going to quickly cover some operations with Lists in Java. Will use lists on my next post. I need a refresher given that lately I have been working with C/C++ and after a few weeks (which in this case included a two week holiday) of not working with a programming language I tend to stumble with the syntax. It all gets back after a day or so of concentrating on the specific language. Continue reading “Java Collections List”
