Scrum, being one of the most well-known lightweight agile process frameworks, is used a lot nowadays. But are we using it right? One might argue that an adaptable framework suggests no „wrong” uses – you’d simply tune it so that it suits your needs just perfectly. Although that might be the case in theory, but looking at how real-world Scrum projects cope with different situations, one might come to a conclusion that it isn’t as straightforward as it seems...
On 18-19 of May in the heart of London “Gartner Application Architecture, Development & Integration Summit” took place. Most probably, you’ve heard about Gartner in relation to their famous Magic Quadrants that emphasize leaders in selected categories. Nevertheless, they do a lot of other interesting stuff including various events organization.
Redis is described by its author Salvatore Sanfilippo as a “strange project”. It’s a distributed cache, it’s an in-memory key-value store, and it’s a notification (publish/subscribe) server. A kind of all-in-one, which is actually good at everything it does. Although Redis keys and values are essentially just strings, one can group them into lists, sets, hashes and all-powerful sorted sets. It also stores numbers very efficiently, which makes such values consume less memory and enables fast numerical operations on them (like atomic increments).
Today we commonly feel the urge to move faster – take notice faster, learn faster, decide faster and act faster. It becomes a struggle. Still we can’t just decide: let’s be faster. There are situations, behaviors, previous experience and other things slowing us down. Let’s gather some analysis on what are the common situations asking for faster action, and what could be the simplest solutions at hand helping us find a way to move in a Fast Forward way – e.g., quick decision making.
The last few months I’ve spent on an interesting Data Mining project. The aim of this data science exercise was to help business reduce customer handling time in a contact center. The project itself and the results we’ve achieved will be covered in my next article, but today I would like to share how I solved a technical issue that came up during the project.

Sure we do! But… Wait a minute. What is ESB? Is it yet another 10-year-old “fancy” technology on its way to Valhalla? Before answering these questions, let us first understand what does this term actually mean.
Siebel provides good tools for working with Siebel Hierarchies, e.g. a developer can query Siebel data using the EAI Siebel Adapter business service, transform the queried data into an instance of external integration object using the EAI Data Transformation Engine business service, and then send the result to an external system. If there are no complicated requirements, and the transformations are straightforward, most of Siebel developers can implement outbound or inbound web service in a couple of hours.
Imagine yourself in the middle of the integration process. You're staring at a requirement asking you to update, let's say a SiebelMessage, that was just queried, and is being processed by one of your workflows in order to be consumed by some 3rd party system somewhere around the edge of the universe. But the update is not just an ordinary update, it has conditions. For example, “Action Code” of the Order Line Item to be passed for further transformation has to be “Add”, and the product of the same OLI has to be some kind of a phone, any kind you can imagine. Add a bit of sorting, a teaspoon of “Get The First That Matches The Condition”, a drop of “Delete That Element”, and you have your recipe of a complex and painful solution you are about to implement.
