https://glewster.wordpress.com/2013/01/24/7db7w-week-4-mongodb
App Dev, BI, Agile and other random stuff. January 24, 2013. 7DB7W Week 4 – mongoDB. Of all the NoSQL databases, mongo is one of the most popular. Once you get hands on with it you begin to see why. Add some nice support from 10Gen and you’ve got a recipe for good times. The book gives a great overview. Mongo is web friendly, scales well, is easy to use, easy to admin and queries well. It is known as a document database. CRUD and Nesting with Javascript. Reading data with find(). Again to quote the book:.

App Dev, BI, Agile and other random stuff. September 19, 2012. 7DB7W Week 1 – PostgreSQL. I have survived the first week of the book on PostgreSQL. It’s been quite a ride, but before I get into that let me go over the relevant points of the database itself. Laquo; Seven Databases in Seven Weeks. 7DB7W Week 2 – Riak. Leave a Reply Cancel reply.

Facilitating meetings with a long and complex agenda – follow up | glewster
https://glewster.wordpress.com/2014/06/28/facilitating-meetings-with-a-long-and-complex-agenda-follow-up
App Dev, BI, Agile and other random stuff. June 28, 2014. Facilitating meetings with a long and complex agenda – follow up. A couple of years back I wrote a post on Facilitating Meetings with a long or complex agenda. Which elicited a few comments. Don’t try to do too much in one session. Try to keep the number of participants to a minimum. Make sure you know who the influential people are. You walk into that room…. Have the right people in the room. The purpose of workshops is usually to bring people to...

Facilitating Meetings with a long or complex agenda | glewster
https://glewster.wordpress.com/2012/02/28/facilitating-meetings-with-a-long-or-complex-agenda
App Dev, BI, Agile and other random stuff. February 28, 2012. Facilitating Meetings with a long or complex agenda. In my new life as an agile coach, I get to work with a lot of different teams over a lot of different technologies and business domains. I’m on a steep learning curve at the moment and luckily have plenty of colleagues to ask questions of, debrief and generally use for moral support. Simply, it is writing up a story card for each item of the agenda. Given that I am delivering a somewhat ...

7DB7W Week 6 – Neo4J | glewster
https://glewster.wordpress.com/2013/01/24/7db7w-week-6-neo4j
App Dev, BI, Agile and other random stuff. January 24, 2013. 7DB7W Week 6 – Neo4J. Neo4j Sounds like it should be a phone shop from the Matrix, Neo4j stands alone in the book as the only graph database option. It stores data in a mathematical style graph and focusses more on the relationships between values as opposed to the commonality of data between sets. It’s great at storing highly variable data in an easy way. Playing with the Neo4j web interface. Algorithms (including the Oracle of Bacon).

7DB7W Week 7 – Redis | glewster
https://glewster.wordpress.com/2013/01/24/7db7w-week-7-redis
App Dev, BI, Agile and other random stuff. January 24, 2013. 7DB7W Week 7 – Redis. Last but by no means least is redis. Redis is at its heart a key-value store with some cool commands but there’s more to it than that. It’s almost a kind of proto-database. Masterfully simple to use and ridiculously fast, redis is a prime candidate for polyglot data technology, complimenting other data management tools. CRUD and data types including Hash List and Blocking List. Sorted Sets, Ranges and Unions.

Impact Mapping for Fun and Profit | glewster
https://glewster.wordpress.com/2012/04/19/effect-mapping-for-fun-and-profit
App Dev, BI, Agile and other random stuff. April 19, 2012. Impact Mapping for Fun and Profit. There are four question levels in an impact map starting with the core Why? Which is the effect we want to create, followed by Who? The basic idea is to be able to visually evaluate a set of options that will allow us to create the desired effect. Let’s look at an example:. Need enough money to get a Ferrari. So our core Why is get a Ferrari for $200K. Next is the Who? After that comes the How? You are commentin...

App Dev, BI, Agile and other random stuff. April 12, 2012. Context Switching, Lean and Agility. I was recently directed by a colleague to this blog article. About Lean Context Switching. Go and read the article before continuing, but if you really would rather not, the basic premise is that context switching is not a bad thing if we can lower the cost of it. Like some kind of verbal Esher drawing, I saw what the author was getting at, but something about it troubled me greatly. The other really bad thing...

7DB7W Week 3 – HBase | glewster
https://glewster.wordpress.com/2013/01/24/7db7w-week-3-hbase
App Dev, BI, Agile and other random stuff. January 24, 2013. 7DB7W Week 3 – HBase. Of all the databases we experimented with during the course of the book, I have to say HBase was the worst in terms of getting it installed and working. Of the week allocated to the chapter, I probably spent 3 days of it just trying to get it up and running. Once again, concisely we covered in the chapter:. Adding data programmatically with JRuby. Compression and Bloom filters. Monitoring disk storage and regions. You are ...
