I am back on the learning Scala trail and it is clear that just reading books and articles or watching videos won’t cut it. It needs to be hands-on coding.

Now that we’ve explored graphs and their basic algorithms, we’re going to add aonther dimension to the vertices: weight. We’ve already programmed them into our Vertex class, but now we’re going to explore how our algorithms must change when weight becomes a factor when traveling on an edge from one vertex to the next.

Mapplication is a tool I built with my co-workers (Rob Shepard, Ethan DeGross, and Alyssa Varner) as a way to rapidly prototype maps for researchers and scholars. It accepts a CSV file upload and outputs a leaflet map. It converts the spreadsheet into valid GeoJSON, allows the users to pick a marker color and map […]

We reduced by over 60% the EC2 instance cost of our 1000+ node globally-distributed log-producing application by migrating it entirely to EC2 Spot Fleet. We discuss some of the issues we faced and also present the log data recovery mechanism which helped enable this migration. 15-20 minute read Background AdRoll operates a globally-distributed real-time bidding platform running on Amazon EC2 . This platform has historically used ....

Hundred years are nothing. Nada. Yes… I know. A lot can happen during a hundred years. Take a look the twentieth century with the two world wars, and the growth of computers and the Internet and the enormous leaps in biology. And the twentieth century is not the only one with drastic changes. Major changes have been happening every century all throughout the last few thousand years. And that’s my point. The total amount of changes is ....

I’m not sure I need it. Maybe you will. It is an exercise in excess. I rarely need something from my home PC because nowadays it’s so easy to store things in the magical cloud . Still, it’s a nice exercise. I have set up remote access on Void Linux and I will describe the process of doing so for that OS. You might encounter some problems if you are using Windows … but if you do you have bigger things to worry about (writing this aroun..

Sharing code from Private libraries is a difficult task. In this post we will see how we can use BitBucket as Private Maven Repository.

Testing your functionality is important, but what happens if other factors come into play? In this blog post we show how trivago handles non-functional testing for every commit and how we scaled it.

We’ve been approached by many customers asking for help in creating hundreds of orgs, many times with identical configurations such as license policies that are shared throughout the company. Setting up integrations and license policies for each org can be time consuming, so we focused on how we could speed up that flow.

Breadth-first search is a great elementary algorithm for searching graphs. In lots of scenarios, BFS will be sufficient to visit all of the vertices in a graph. In others, it’s very important that you choose the right algorith. Today we’ll be exploring depth-first search (DFS), a very similar algorithm that also explores all vertices by walking down neighboring edges, the difference is in the order in which those vertices are explored.

I’m going to feel like an old man for this post, but if you were born post 1995, it is likely that you have no idea what I’m talking about in this post, crazy as this sounds to me. Before there was a phone in every pocket, there were land lines. It is like today’s phone, but much larger, you could only do voice calls and if you wanted to screen your calls you needed to buy another appliance. If you’ll watch the first few sessions of Frien....

The Oracle SQL Developer team has released version 18.3 of this tool. My favorite new feature in this version is its ability to save SQL Monitoring reports in HTML format! Adobe Flash is finally not needed for sharing graphical SQL Monitoring reports. Here’s an example output, it looks pretty nice and clean: The report is reasonably navigatable, has tooltips (useful for identifying wait classes for example) and you can also rearr..

I believe one of the most, if not the most, important applications of blockchain and smart contact technology will be the establishment of self-sufficient organizations that are completely virtual: They will use virtual currencies like Ether and ERC-20 tokens to handle all transfers & storage of value. Their collaboration & making of crucial decisions will be handled by smart contacts. Their members will consist of pseudo-anonymous indivi..
