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.

Yesterday morning I attended a one hour webinar sponsored by the Association for Computing Machinery titled ACM Queue Case Study Q&A: Always-On Time-Series Database. It was very interesting. There was no presentation segment. There were only questions. The presenter, Theo Schlossnagle which is the founder of Circonus was very eloquent and seems very versed in the technology and their products.
During the conference I made several notes and searched for several topics that I found of interest. I will be reading the associated pages later this week. Continue reading “Reverse Operations Revisited”
It is a Saturday morning in the Twin Cities of Minneapolis and St. Paul. As we have been doing for a few months, my wife and I drove to the Costco store in Minneapolis, met with our son and went grocery shopping. Today we were not able to find Three Berry Blend bags. We got separate bags of strawberries and blueberries. Our son will stop later today at the Costco in Eagan. MN and will see if he is able to find a couple bags of mixed berries and a box of pens that we forgot while in Minneapolis.
This week I watched the Association for Computing Machinery (ACM) webinar “Lessons from COVID-19: Efficiency vs. Resilience” by Moshe Y. Vardi. It seems that the webinar is only accessible if you are an ACM member, which I am. I enjoyed the point he made of efficiency versus resilience not only at the software but also at the political level. At no point he mentioned politicians or political parties. In my opinion, it is a very good one-hour webinar worth your time. Continue reading “Backspace String Compare”
It is Friday afternoon and we are still observing social distancing restrictions and working from home. That said, things are slowly relaxing and more people are out and about. The number of cars on the road has more than tripled since the stay home order started a couple months ago. Please observer social distancing and wear a mask when in public. It is for your well being, your family and friends, your country, and all human beings on this planet.
Currently I am running some tests and writing documentation on some code I wrote earlier during the week. During idle times I am putting together the contents for this post. Hope to be done in the next hour or so. My wife left a minute ago to walk (keeping social distancing) with a neighbor. The day is sunny but rather cold. The temperature is in the upper 40’s. Continue reading “CS50 2019 Lecture 6 – Python”
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”
Last evening I read the article “Programmable Solid-State Storage in Future Cloud Datacenters” by Jaeyound Do, Sudipta Sengupta and Steven Swanson which appeared in volume 62 number 6 edition of Communications of the ACM. This morning I read it once again. As you might already know I am passionate about storage and have been working on it for a while. The article deal with SSD drives and how they can help improve performance by providing compute resources close to the data. Continue reading “Arrays Left Rotation”
It is getting late in the day for me. I am a believer in deep work so several months ago I decided to get up early morning and study for a couple hours. So far, it has worked very well for me. I have set a wakeup alarm for 05:00 AM 7-days a week. Typically I am awake between 04:30 and 05:00 so I just turn off the alarm and head down to my home office. Around 05:00 PM I feel the work day coming to an end and am ready to punt. I use EyeDefender to break every two hours. During my 5 to 10 minute breaks I walk and get some fresh water. What can I say; it works for me. On weekends I tend to just do two are three blocks. On work days I tend to do five. Continue reading “ACM and Coursera”
