It is past 06:00 PM CST in the Twin Cities of Minneapolis and St. Paul. I am quite tired and it is only Tuesday. Hope your week is going smoother than mine.
Earlier in the day I read the article “Let’s Not Dumb Down the History of Computer Science” by Donald E. Knuth, Len Shustek in Communications of the ACM, February 2021, Vol. 64 No. 2, Pages 33-35. If you have trouble accessing the article then you should be able to watch “Stanford Lecture: 2014 Kailath Lecture: Stanford Professor Donald Knuth” on YouTube.
In a nutshell Donald Knuth expresses the need for Computer Science history to be documented. Philosophically speaking I believe he is right on the point. Continue reading “Find a Corresponding Node of a Binary Tree in a Clone of That Tree”
Good morning. Hope you are doing well. It is a dark, foggy and cold morning in the Twin Cities of Minneapolis and St. Paul. I woke up around 05:00 AM. I finished reading the article Does Facebook Use Sensitive Data for Advertising Purposes? article in the Communications of the ACM magazine. I though the article was interesting. Apparently Facebook has a set of several thousand categories of which up to 1000 can be applied to each user. Not sure if there is an opt out setting. The authors of the paper suggested a tool that can be used in a couple browsers to check and delete the advertising labels assigned to your account. Continue reading “Can you solve it? Java Solution”
Today it is Friday. I woke up around 04:30 AM. I wanted to generate this post before breakfast. In addition the cleaning lady will be here around 08:00 AM. In addition I have to prepare breakfast for my wife and me and shower.
I started to read an article regarding Facebook on the last issue of Communications of the Association for Computer Machinery. The article Does Facebook use sensitive data for advertising purposes? called my attention. I have not finished reading the article. I will make some comments when done. Continue reading “Balanced Split”
As I mentioned in my last post, I read the article “A* search: what’s in a name?” by James W. Davis and Jeff Hachtel. If interested, you may find the article in Communications of the ACM, December 2019, Vol. 63 No. 1, Pages 36-37. The article deals with the name of a search algorithm that was originally published in 1968 by Peter Hart, Nils Nilsson and Bertram Raphael of Stanford Research Institute.
My interest was not much about the name but to be able to experiment and understand the algorithm. There are so many algorithms in Computer Science that adding one more to my list is always welcomed. I do not plan on memorizing the algorithm but if the time comes when I might need to search a graph, I will have one more choice in my toolkit. Continue reading “A* Search Algorithm”
Time flies when you are having fun; at least that is how the saying goes. Today is Saturday and I am on my second and last block of the day. After breakfast I prepared the pizza dough and put it in a bowl covered with plastic film for it to rise. During the break between blocks my wife and I checked the dough. It is touching the plastic. It has tripled its size.
For lunch we are going to make and bake a few small and thin pizzas. We are going to mix and match toppings and are expecting to have a few leftover pizzas. Tomorrow we are going to make “baba” (an Italian yeast cake). Will have a few and the rest with the pizzas will be delivered to my oldest son. Continue reading “Priority Queue”
This morning I woke up and put my cell phone on the tile ledge surrounding the Jacuzzi tub in the bathroom of my bedroom. The ledge is 22 inches in height. My Samsung Galaxy 8+ had on an “i-Blason Samsung Galaxy S8+ Plus case, [Ares] Full-Body Rugged Clear Bumper Case with Built-in Screen Protector for Samsung Galaxy S8+ Plus 2017 Release (Black)” cover. It fell and hit the floor. The screen cracked on one corner. Not sure what was the purpose of the protector. I will be replacing my cell phone in the near future with a Google Pixel 3a XL.
