See the original posting on DZone Python

Smart mobile teams know that delivering a 5-star app is more than just finding a good business use-case and designing an app with wow experience; it’s also about ensuring amazing app performance. Apps that perform well will engage the customer — poor app performance is a sure fire way to lose the customer and their business.

Open Source contributions are often anonymous and the rewards are intangible. A little bit of tangibility is a huge thing. There are unsung heroes at every hackathon and tech meetup who could benefit from some recognition….

On Choosing Software by “What is Best for the Business”

Geek Reading March 19, 2015

Just in case you did not think mobile payments were about to take off, Facebook introduces friend-to-friend payments. Clearly, Facebook wants some skin in the game before the industry really gets going. GigaOm may be gone, but the Structure conference went on because the attendees organized their own conference. This is interesting for a few reasons. First, the power of the people is obvious….

Bend the Spoon

See the original posting on DZone Python

Bend the spoon is a phrase we use quite a bit here at LeadingAgile. I don’t want to hear what’s happening, I want to hear what we need to make happen… and what we are doing to make it happen. I don’t want to hear why we can’t do something, I want to talk about what we are doing to make reality conform to our will.

If it’s impossible… bend the spoon.

How Much Does Your Manager Need to Know?

See the original posting on DZone Python

In this social media age I am often surprised by the reaction to what I say online. Usually this is not by the reaction to what I say but rather the lack of reaction. I’ve lost track of the number of times I’ve written what I think is a killer-blog post, or a super meaningful tweet, pushed it out in great anticipation and… well… nothing.

Just goes to show: what you think is good and…

Excuses For Not Testing

See the original posting on DZone Python

As I started my own journey into unit testing, I slowly began to realize that it was really easy to come up with reasons to NOT test my code as I was writing it, even once I understood what that was supposed to look like. The reason I think most programmers don’t unit test code, once they understand what it is they are supposed to be doing is that they don’t feel like they have…

Cultural Judo: How to Change Culture Without Changing Culture

See the original posting on DZone Python

There are a bunch of us out there that are super passionate about this notion of agile as a cultural framework… or a value system… or a mindset. If you’ve been following this blog for any length of time, I suspect you’ll know where I stand on this. I think that culture, values, and mindset are important… but they aren’t why we adopt agile. We adopt agile to build better software,…

Code Golf: Pi Day

See the original posting on DZone Python

When it comes to ingenuity, Code Golf is my absolute favorite thing in the developer space. Code Golf, like the game of golf, is an exercise in brevity – the fewest lines of code and the smaller the file size, the better. It requires creativity, knowledge of your craft, and perseverance.So in order to showcase the brightest members of our community, DZone will be holding a weekly Code Golf…

The New Agile: Decisions, Decisions

See the original posting on DZone Python

In the new knowledge economy, the winners are the ones who learn quickly. But learning means nothing, if it cannot be applied to the business. So the winners are the ones who learn, and use that knowledge by deciding where to go, and what to do next.

If decision making is the king maker, it can also come back to haunt us. Because high stakes can go either way.

Last time, we talked about how to…

Solr 5: Replication Throttling

See the original posting on DZone Python

With the release of Solr 5.0, the most recent major version of this great search server, we didn’t only get improvements and changes from the Lucene library.  Of course, we did get features like:

segments control sum
segments identifiers
Lucene using only classes from Java NIO.2 package to access files
lowered heap usage because of new Lucene50Codec

…but those features…

“Too Easy”

See the original posting on DZone Python

When people sneer at a technology for being too easy to use, it’s worth trying out.

If the only criticism is that something is too easy or “OK for beginners” then maybe it’s a threat to people who invested a lot of work learning to do things the old way.

The problem with the “OK for beginners” put-down is that everyone is a beginner sometimes. Professionals are often beginners…

Long-Running Async and Memory Fragmentation

See the original posting on DZone Python

We are working on performance a lot lately, but performance isn’t just an issue of how fast you can do something, it is also an issue of how many resources we use while doing that. One of the things we noticed was that we are using more memory than we would like to, and even after we were freeing the memory we were using. Digging into the memory usage, we found that the problem was that we…
