CS50 2019 Lecture 6 – Python

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.

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”

Arrays Left Rotation

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”

ACM and Coursera

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”
