Back to Rants

I had the pleasure of sharing my recent learnings about Bluetooth Low Energy in a Internet of Things meetup in Stockholm. It was inspired by a similar meetup held in San Fransisco back in October. I would like to share some learning resources for people who attended the meetup and this is what this post is about. I would try to make this list grow over time. Edit: I am dumping more links here from Droidcon Stockholm Videos First the basics. I think the best place to start and get excited is from youtube videos  There are lots of videos from Bluetooth Tech channel, from home automation, security etc.  If you want to go more in depth you can watch Robin Heydon from CSR do a really nice intro to BLE. This intro is similar to other webinars that are available out there. You should watch the whole series to get a basic idea This following video presents BLE from a Linux perspective. I think it introduces too much detail without context, but can be worth watchi...

I am really glad that interest in Neo4j education is picking up and NeoTechnolgoy is taking a fun approaches to help people learn graph databases. These efforts tie in neatly with my suggestions regarding Neo4j community outreach. Back in 2012 we had the Neo4j heroku challenge . At that time Cypher was just coming out and the aim of heroku challenge was to get people comfortable with code/cloud and Neo4j. In the last year or so Cypher has evolved considerably and now it is a great initiative by the Neo4j-community-team to hold a challenge that focused on Cypher and graph modelling. In this post I would like to go through my personal favourite gists from this challenge. I have a " fair " understanding of modelling with graphs; yet I learn some thing new and interesting, almost every time, when I am looking at other people's graph models (and that was my personal motivation when I began reviewing the gists ). I am not sure how the voting for this challenge will be d...

This is like the fifth time in the last 10 years that I have started a new blog. I am still trying to find a balance between what to post/share with the world and what to keep it to my self. My last blog was titled "No more rants" and today I have forcefully retired it.  Why (you may ask?). My initial goal of that blog was to only focus on technical content and not say too much about other stuff (like politics, my travel adventures, life in northern Europe). But now I have changed my mind about it because I missed writing. I think writing helps you become a better person, since one(usually) takes time to reflect on the topic. It is another thing altogether that with blogs you open your self up to the world and that can have some consequences (mostly some thing you wrote a while back can come to bite you back, example in my case was bashing of a company for no reason other than fashion, and of course bad writing that just make you look un-intelligent.  I think I w...

I copied this post from my previous blog. This post is about some ideas for helping the the cause of NoSQL and Neo4j education.    The purpose of this (longish) post is to jot down my ideas about education of  Neo4j  in it's community. This post is in response to an irc/online  meeetup  called on Sep  12th   6th 2012. I have been involved with Neo4j community for almost a year now. It all started with me attending  Goto Aarhus  2010 as a student volunteer/crew. Since then I have been trying to learn more about the subject of Neo4j and NOSQL for my personal and professional use. I am by no means an expert in Neo4j, or in spreading knowledge (pedagogy). But as a loud mouth trouble maker I do have some opinions/ideas of my own.  There are many aspects of Neo4j that I am interested in ( Cypher  being one,  Spring-Data  integration being other). But one topic that I am deeply interest...
