In the past few days there have been several announcements by both car and device manufacturers that self driving cars are almost a reality and to make that possible new and cheaper devices are being introduced to help.
It seems that newer LIDAR devices are improving in range and precision while their prices are coming down. This should help. On the other hand researchers are working on algorithms to check that sensors are getting more reliable. I read an article today that LIDAR systems can be tricked to not detect something or to detect something that is not there. Continue reading “Almost Sorted”
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”
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”
In the past few weeks I have been reading several articles about how great Visual Studio Code is and how software developers are starting to use as their main IDE. I have been using VS Code on and off but have made up my mind that from now on for Java development I will only use Visual Studio Code. I have installed Eclipse and IntelliJ in my machine, both of which I have used for Java development. I will leave both of them installed for compatibility purpose only. Will let you know my findings towards the end of the year. Continue reading “Cats and a Mouse”
In the past few days the temperature in the Twin Cities of Minneapolis and St. Paul has been lower than average. The days have been cloudy and rainy. Today the sun might peak in the afternoon and the temperature will hopefully reach 55 F. On the positive side the forecast for Saturday is sunny and temperatures in the low 70s. Hopefully will be able to grill and spend a few hours outside walking.
In this post I will cover interacting with MongoDB using Node.js via the Mongoose module. I will not say much about Installing MongoDB on Windows or Using the MongoDB Shell due to the fact that I have covered such topics on previous posts. I am using the Windows 10 OS due to the fact that several tools I use to generate the post are installed in this Windows machine. You can follow just as well if you decide to use Linux. The installation instructions provided by MongoDB are well written and are easy to follow. Continue reading “MongoDB for RESTful Service”
Given that one needs to start with some level of requirements, we will use the following short and simple statement:
“Implement a very simple RESTful API for a storage server that supports store, query, retrieve and delete operations using DICOM data”. Continue reading “Basic RESTful Service – Part I”
