Elixir is a really awesome language which runs in the Erlang Virtual Machine ( BEAM ). So it takes advantage of all the concurrent and distribution features of Erlang by free. In order to demonstrate it I have decided to develop a proof of concept (PoC) of a Publisher-Subscriber system only using Elixir. Coding I will begin building a Publisher.
After the Facebook F8 of this year the new buzzword is ChatBot and I decided to build one using Telegram Bot API . My ChatBot's name is Monkey Note Bot and it is a Telegram Bot which will take care of your lists of notes. Typing a command like "Addnotes shopping bread. milk. eggs" (Dots are easier in the mobile than commas) MonkeyNoteBot will add to the list "
Currently all systems try to be real time systems, or at least soft-real-time systems. In order to get it, most of the systems abuse of pulling methodology. This approach provokes a lot of useless requests that cause overloading. Why are they useless? Because this approach tries to catch the changes requesting and requesting over and over, but it will always have a delay. The new data has to be there when the request is done.
Who have not heard about microservices ? Microservices is a software architecture approach which tries to decouple functionalities which will be served by very focused and small systems. When I say small I mean smaller. These systems will provide their functionalities through a known API . Therefore this approach will help us to scale up our software systems by breaking them up (good bye to monolithic system problems !
This week I had to identify from where the users are connecting to one of our platforms in Palmtree Statistics. The http request always provides the IP of the client, and that was enough, but I wanted to get something else. Torip is an open source project based on Tornado Networking Library . Torip will provide you information like city, country or the url of google maps which will point to the client.
I have begun to work with Intel Edison in order to adapt machines with limited or even none connectivity to the movement of IoT . This tiny platform is already prepared to work with Python but, if you want to work with Python, you want to work with pip . Pip is an amazing package manager where we can find almost all python libraries that we are going to use.
I have to say that I love maps and for a long time I have wanted to check out the complementary tools: Leaflet maps and NoSQL geo-function. Hence, I decided to build a location app which will help people to find their closest airports. I evaluated ArangoDB and MongoDB as NoSQL data bases.
Real-time analytics is very trendy. Nowadays, everyone wants to analyze the data that they have, even if those data are not very useful, and they want the results as soon as possible, even if they can wait for those results. One of the most powerful data sources are the social networks and inside this group, Twitter. Therefore I decided to build a system (as proof of concept) in order to analyze tweets related to BigData.
