Database Storage in Go with Structable

Javalobby Syndicated Feed - Wed, 20-Aug-14 23:00
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...

The argument for testing performance in production

Javalobby Syndicated Feed - Wed, 20-Aug-14 22:30
I encounter teams that do formal performance testing less frequently than in the past. For many teams, this is just the result of being spread too thin across QA and not having the resources to do performance testing well. However, in some more agile shops there’s an active argument against performance testing, especially load testing. Preview Text:  ...

Top Redis Headaches for Devops: Client Buffers

Javalobby Syndicated Feed - Wed, 20-Aug-14 22:30
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

Javalobby Syndicated Feed - Wed, 20-Aug-14 22:30
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

Javalobby Syndicated Feed - Wed, 20-Aug-14 22:00
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...

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

Javalobby Syndicated Feed - Tue, 19-Aug-14 23:00
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,...

BDD, Automated Acceptance Tests and Continuous Delivery: Dealing with Scenarios that are "Work-in-Progress"

Javalobby Syndicated Feed - Tue, 19-Aug-14 23:00
One of the principle rules of Continuous Integration (and Continuous Delivery) is that you should never knowingly commit code that will break the build. When you practice test-driven development this is easy: you write a failing test (or, more precisely, a failing "executable specification"), make it pass, and then refactor as required. You only commit your code once you have refactored and ran...
