The Need To Review The Agile Manifesto

Java Lobby Announcements - 11 hours 59 min ago
In 2001, when the Agile Manifesto was first published, technology in the workplace looked and felt very different to how it does today. High-speed Internet and data channels were still relatively new and communication channels more limited in variety. The sharing of information was nowhere near as easy as it is today. Nothing lived in the cloud and ‘drop box’ was something you did by...

Database Storage in Go with Structable

Java Lobby Announcements - 11 hours 59 min ago
I'm not a huge fan of ORMs. Don't get me wrong, I'm not about to start a campaign against them. I know that many people find them to be a great abstraction layer on their database. But I usually feel more productive with my query writing when I can just write SQL. Okay, not always. Writing plain old CRUD (Create, Read, Update, Delete) queries is a mindless chore equivalent to scrubbing the...

Top Redis Headaches for Devops: Client Buffers

Java Lobby Announcements - 12 hours 29 min ago
Photo by Jay Aremac Originally written by Yaron Dolev Preview Text:  Because Redis is a remote server, a client's request will take significantly more time to return to the client than the actual fetching of data from RAM by Redis' CPU. The implication of this difference is that Redis would have been tied up serving the request for the...

Ionic and Cordova's DeviceReady: My Solution

Java Lobby Announcements - 12 hours 29 min ago
Folks know that I've been madly in love with the Ionic framework lately, but I've run into an issue that I'm having difficulty with. I thought I'd blog about the problem and demonstrate a solution that worked for me. To be clear, I think my solution is probably wrong. It works, but it just doesn't feel right. I'm specifically sharing this blog entry as a way to start the discussion and get some...

Question 6 is a trap, a very useful one

Java Lobby Announcements - 12 hours 59 min ago
In my interview questions, I give candidates a list of 6 questions. They can either solve 3 questions from 1 to 5, or they can solve question 6. Stop for a moment and ponder that. What do you assume that relative complexity of those questions? Questions 1 –5 should take anything between 10 – 15  minutes to an hour & a half, max. Question 6 took me about 8 hours to do, although...

@CloudExpo | #CloudComputing: A Quick Primer

JDJ - Wed, 2014-08-20 23:00
“The cloud will transform everything about technology.” This statement is better suited for 20 years ago when the cloud was in its infancy. In 2014 the statement should be that “The cloud has taken over technology.” Cloud computing has been around since the sixties believe it or not, but over the past few years the industry has recognized the concept better as more organizations are embracing cloud technology and more vendors are creating amazing cloud-based business solutions.

It's Not NoSQL Versus RDBMS, It's ACID + Foreign Keys Versus Eventual Consistency

Java Lobby Announcements - Wed, 2014-08-20 08:00
The Background Coming from a diverse background and having dealt with a number of distributed systems, I routinely find myself in a situation where I need to explain why foreign keys managed by an ACID compliant RDBMS (no matter how expensive or awesome), lead to a scaleability problem that can be extremely cost prohibitive to solve. I also want to clarify an important point before I begin,...
