Raspberry Pi - Daily Deviations Picture Frame

Over the past couple of weeks I’ve been tinkering with it in the evenings and I’m absolutely blown away by this little device. With a $35 dollar price tag, the RPi is a surprisingly capable computer. You obviously won’t be doing some of the CPU intensive tasks you would be used to on your PC, but its a great way to tinker and learn and maybe find a great practical use for it along the way. Map / Reduce – A visual explanation. Map/Reduce is a term commonly thrown about these days, in essence, it is just a way to take a big task and divide it into discrete tasks that can be done in parallel.

Map / Reduce – A visual explanation

A common use case for Map/Reduce is in document database, which is why I found myself thinking deeply about this. Let us say that we have a set of documents with the following form: And we want to answer a question over more than a single document. That sort of operation requires us to use aggregation, and over large amount of data, that is best done using Map/Reduce, to split the work. Map / Reduce is just a pair of functions, operating over a list of data. From post in docs.posts select new { post.blog_id, comments_length = comments.length }; from agg in results group agg by agg.key into g select new { agg.blog_id, comments_length = g.Sum(x=>x.comments_length) };

Online Learning: A Bachelor's Level Computer Science Program Curriculum (Updated)

A few months back we took an in-depth look at MIT’s free online Introduction to Computer Science course, and laid out a self-study time table to complete the class within four months, along with a companion post providing learning benchmarks to chart your progress. In the present article, I'll step back and take a much more broad look at com-sci course offerings available for free on the internet, in order to answer a deceptively straightforward question: is it possible to complete the equivalent of a college bachelor’s degree in computer science through college and university courses that are freely available online? And if so, how does one do so? The former question is more difficult to answer than it may at first appear. Yet, this does not mean that all the necessary elements for such a curriculum are not freely accessible. Introductory Courses.

Coding for SSDs – Part 1: Introduction and Table of Contents. Introduction I want to make solid-state drives (SSDs) the optimal storage solution for my key-value store project.

Coding for SSDs – Part 1: Introduction and Table of Contents

For that reason, I had to make sure I fully understood how SSDs work, so that I can optimize my hash table implementation to suit their internal characteristics. There is a lot of incomplete and contradictory information out there, and finding trustworthy information about SSDs was not an easy task. I had to do some substantial reading to find the proper publications and benchmarks in order to convince myself that, if I had to be coding for SSDs, I would know what I was doing.

Then I figured that since I had done all the research, it would be useful to share the conclusions I had reached. The most remarkable contribution is Part 6, a summary of the whole “Coding for SSDs” article series, that I am sure programmers who are in a rush will appreciate. My only regret is not to have produced any code of my own to prove that the access patterns I recommend are actually the best.
