AND Product

Yesterday morning I watch most of the Association for Computing Machinery (ACM) webinar “OOPS! Learning from Surprise at Netflix”. The presenter was Lorin Hockstein who is a senior software engineer at Netflix. For what I was able to get out from the presentation is that when an issue in production appears, it is important to learn from it to make sure the code is updated to prevent the issue from ever happening again. That may require from simple changes to deeper design or even architectural modifications. Continue reading “AND Product”

Jumping on the Clouds

Earlier today I was scrolling through YouTube videos and Jumping on the Clouds HackerRank Solution by JAVAAID came up. About the time this channel was starting the author and I exchanged some messages. In general I do not spend too much time watching this channel, but I became curios today and decided to solve the challenge and then watch the video.

Besides that and work not much else going on. My wife cooked too much for lunch so she decided to go with a friend for a walk and some shopping to the Mall of America. I assume she will be back towards the end of my workday. We need to get a birthday card for one of my sons. Hopefully she remembers and gets it while at the MOA. Continue reading “Jumping on the Clouds”

Sansa and XOR

I just got off the phone with my youngest son. He was on his way to work. He calls every workday and I call him every weekend. It has become some type of tradition. Today the weather in the Twin Cities of Minneapolis and St. Paul is sunny and cold with the temperature at 11 F. In Madison, WI it is a few degrees warmer. Continue reading “Sansa and XOR”

Larry’s Array

Over the weekend my wife and I tried baking baba (Italian yeast cake) using a large mold. Typically baba is baked in individual small molds but it takes a while to grease and fill them. We tried for the first time using a large mold. All was going well until we put the mixer bowl covered with plastic in the oven with the lights on for it to ferment and double in size. After a couple hours the dough had pushed its way out of the bowl and spilled over the oven floor. We had to clean the mess before baking. We also moved the contents of the bowl into the large baking mold. Continue reading “Larry’s Array”

Bigger is Greater

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”

Organizing Containers of Balls

Hope you had a happy Thanksgiving Day with your family. As usual there is lots of anticipation and suddenly it is over.

Some years my wife and I have gone out shopping on Black Friday, but as time goes by, it seems that most of the shopping can be done on-line. For that, the best day seems to be Cyber Monday. Besides the ability of shopping from the computer on Cyber Monday, there was a lot of snow and ice over in the Twin Cities of Minneapolis and St. Paul over the Thanksgiving holiday. One of my wife’s nephews posted on Facebook a video of cars slipping and sliding all over in Minneapolis. Continue reading “Organizing Containers of Balls”

Java Static Initializer Block

It is Sunday at 07:36 AM in the Twin Cities of St. Paul and Minneapolis. I try to get in at least a couple of 2-hour blocks each weekend day. I can see from my home office that the day is still dark although sunrise occurred at 07:14 AM.

Lately I have not posting much due to the fact that I am working on software that I would like to have finished by the end of this week. I like the project because the requirements were quite vague. In addition, the hardware when I received it had a couple issues. After contacting the vendor I had to wait a week before I could take the unit to be repaired. It just took a few hours for me to drive to the OEM’s office, have it looked at and repaired and get back home. Very knowledgeable technical support! Continue reading “Java Static Initializer Block”

Breaking the Record

I am writing a white paper on Agile. Hope to get done by the end of this week. I will be looking where to start posting it and future ones besides this blog.

I received a message for an easy challenge from HackerRank. Just to warm up I decided to tackle it. If interest in the Breaking the Records challenge please take a look at the description and then go for it. Continue reading “Breaking the Record”

ACM ICPC Team

It is Thursday April 11 and this area of the Twin Cities of Minneapolis and St. Paul has received since yesterday around noon to today around 04:00 PM about 10 inches of snow. Around noon today the snow stopped and we start receiving freezing rain. Schools are closed and there is very little traffic in the area.

According to the forecast, tomorrow will be raining during the day. Not sure if the precipitation will turn into freezing rain. One way or the other, staying home working is not a bad idea. Continue reading “ACM ICPC Team”
