No Need to $Watch AngularJS “Controller As”

See the original posting on DZone Python

In a previous blog post I discussed how to use Angular’s extend to improve code quality and reusability. In my example I used the new controller as syntax. I see a lot of discussion online about this approach.

In a previous part of this tutorial series, we showed how you can create a simple web application using Django: How to develop a basic and very first website using Django.

In this post we are going to see how we can use Templates in Django to render HTML code on a web page. Initially we hard-coded the HTML part in views (views.py).

JS crypto goto fail?

See the original posting on DZone Python

 tldr; A long, passionate discussion about JS crypto. Use slides for an overview.

Javascript cryptography is on the rise. What used to be a rich source of vulnerabilities and regarded as “not a serious research area”, suddenly becomes used by many. Over the last few years, there was a serious effort to develop libraries implementing cryptographic primitives and protocols in JS….

Software development becoming less mature?

See the original posting on DZone Python

Michael Fogus posted on Twitter this morning

Computing: the only industry that becomes less mature as more time passes.

The immaturity of computing is used to excuse every ignorance. There’s an enormous body of existing wisdom but we don’t care.

I don’t know whether computing is becoming less mature, though it may very well be on average, even if individual developers become more…

Adding the CAM8000-D Camera Module to the RIoT Board

See the original posting on DZone Python

One reason for me to buy the RIoT board was that it has a camera connector. So I had ordered the CAM8000-D module from Farnell (part number 2362812). The Farnell product page was not clear if it comes with the 30pin FPC cable, but luckily, it shipped with it:

R: ggplot – Plotting back to back charts using facet_wrap

See the original posting on DZone Python

Earlier in the week I showed a way to plot back to back charts using R’s ggplot library but looking back on the code it felt like it was a bit hacky to ‘glue’ two charts together using a grid.

I wanted to find a better way.

To recap, I came up with the following charts showing the RSVPs to Neo4j London meetup events using this code:

Scaling Big Data fabrics

See the original posting on DZone Python

When people talk about Big Data, the emphasis is usually on the Big. Certainly, Big Data applications are distributed largely because the size of the data on which computations are executed warrants more than a typical application can handle. But scaling the network that provides connectivity between Big Data nodes is not just about creating massive interconnects.

In fact, the size of the…

How Pairing & Swarming Work & Why They Will Improve Your Products

See the original posting on DZone Python

If you’ve been paying attention to agile at all, you’ve heard these terms: pairing and swarming. But what do they mean? What’s the difference?

When you pair, two people work together to finish a piece of work. Traditionally, two developers paired. The “driver” wrote the piece of work. The other person, the “navigator,” observed the work, providing review, as the work was…

Scenario planning for first-line managers

See the original posting on DZone Python

A common meme in the strategic planning world is that there is no one pre-determined future. The objective in strategic planning is not to forecast a single outcome but rather to identify a number of possible outcomes. Preparedness comes in having thought through multiple possible end states, and agility comes from the ability to quickly identify which of those end states is coming to fruition…

GitHub Commit Storytelling: Now or Later

See the original posting on DZone Python

When you are making GitHub commits you have to provide a story that explains the changes you are committing to a repository. Many of us just post ‘blah blah’, ‘what I said last time”, or any other garbage that just gets us through the moment. You know you’ve all done it at some point.
