Automatic continuous development and delivery of a hybrid mobile app

ven, 12/07/2018 - 09:01

Offering a mobile app is essentially a business requirement for organizations today. One of the first steps in developing an app is to understand the different types—native, hybrid (or cross-platform), and web—so you can decide which one will best meet your needs.

Is open source wealth distribution fair?

ven, 12/07/2018 - 09:00

If wealth is the abundance of valuable possessions, open source has a wealth of software. While no one “owns” open source, some are better than others at converting this communal wealth to personal wealth.

Many open source project maintainers who produce free open source software do not have a model for deriving income from the assets they have created. However, companies that use open source software to enhance their products and services convert this valuable asset into income.

How to view XML files in a web browser

jeu, 12/06/2018 - 09:01

Once you learn that HTML is a form of XML, you might wonder what would happen if you tried to view an XML file in a browser. The results are quite disappointing—Firefox shows you a banner at the top of the page that says, "This XML file does not appear to have any style information associated with it. The document tree is shown below." The document tree looks like the file would look in an editor:

jeu, 12/06/2018 - 09:00

Do your efforts to improve software development fall short due to confusion and too much debate? Does your organization have a clear picture of what is achievable, and are you sure you’re moving in the right direction? Can you determine how much business value you've delivered so far?

5 reasons to give Linux for the holidays

mer, 12/05/2018 - 09:02

Every year around this time, people ask me about the best computer to give (or get) for the holidays. I always give the same answer: Linux. After all, if you want your recipients to be happy, why wouldn't you give them the best operating system on the planet?

Many people don't realize they have options when it comes to computer operating systems. Just recently, two friends (who didn't do their research) fell for the clever marketing and bought brand-new systems at premium prices. I'm willing to bet that within six months they'll be dissatisfied with those expensive computers.

Testing Ansible roles with Molecule

mer, 12/05/2018 - 09:01

Test techniques play an important role in software development, and this is no different when we are talking about Infrastructure as Code (IaC).

Developers are always testing, and constant feedback is necessary to drive development. If it takes too long to get feedback on a change, your steps might be too large, making errors hard to spot. Baby steps and fast feedback are the essence of TDD (test-driven development). But how do you apply this approach to the development of ad hoc playbooks or roles?

Blueprint for a team with a DevOps mindset

mer, 12/05/2018 - 09:00

I've had the privilege to work with some of the brightest minds and leaders in my 33 years of software engineering. I've also been fortunate to work for a manager who made me question my career daily and systematically broke down my passion—like a destructive fire sucking the oxygen out of a sealed space. It was an unnerving period, but once I broke free, I realized I had the opportunity to reflect on one of the greatest anti-patterns for effective teams.

3 implications of serverless

mar, 12/04/2018 - 09:02

If you strip away all of the modern conveniences and features that make up your internet experience today, what you're left with is the client-server model. This distributed network was what the internet was built on in the beginning, and that part hasn't changed. You could say, it is still serving us well.

So, when people talk about serverless, what does it mean? Well, it doesn't mean servers are GONE. Of course not: That "client-server model" is still the backbone of how things are getting done.

What is open leadership?

mar, 12/04/2018 - 09:00

Leadership works differently at Red Hat. In our open organization, people don't just receive the status of "leader" when appointed to a position or given a title. Instead, leaders earn their leadership positions when they adopt a certain combination of behaviors and mindsets.
