On databases: B+ trees

Since I have been busy with a new project for school and since it seems promising, let’s talk more about it! As can be guessed by the title it is a database. And as people might know B+ trees are one of the most important parts of a good database. Datastores, key-value stores, relational databases, graph databases all have a B+ tree or at least a B tree. These trees are data structures that are used to store and lookup key values within databases.

Searching made easy.

An important note is that this post will explain search problems, but these are not “how to lookup relative hits in multiple texts” but more “given a map, what is the best route from A to B”. I will discuss search problems in general, Astar and other search algorithms.

So try it with your favourite language.

Email notifications for Dell LifeCycle with Linux

So I got myself a fancy new server. It really is great, I really love it, it performs great and I noticed that there was an option to execute an executable when an event was generated by the LifeCycle manager (which checks the status of all the hardware for you), which is awesome. But I couldn’t find an application which sends the report to me. I searched, and searched, but found only solutions for windows or I needed to lay down money for a simple script. My solution: I will make my own simple script and share it.

Welcome

Hi and welcome to littledev,

I just uploaded WordPress and if this is the only post around that probably means you found me rather early!

On this blog I will write about the little and big things I endure and discover while being a active developer. The first post will likely be an introduction of myself and after that I will talk about code and tech stuff… Mostly code though.

Till soon!
