My previous post “The Degradation of Java Developers” sparked several interesting discussions. One of the major topics was if today’s developer has to know what’s going on under the hood of a particular framework. To be more specific, if Hibernate, a popular object-relational framework, can hide from your how the database objects are being created or manipulated, why learn SQL? One reader stated, “First of all, Hibernate (JPA, actually) is a step forward since it reduces most of the boilerplate SQL of the obvious kind. In applications with around 100 tables in the SQL database it is not challenging to explicitly write data access objects by hand.”
I can agree with this to some extent, especially when we talk about such mature and stable framework as Hibernate. But this framework was created to spare the programmer from writing tons of mandane SQL and JDBC code. Hibernate might help you here, but it’s hard to imagine that if the storage consists of 100 database tables no queries created by Hibernate have to be fine-tuned and optimized. In such cases if a person who uses Hibernate doesn’t know SQL – it turns him into a useless team member.
About two months ago I was making my usual morning promenade along the beach. Every morning a couple of tractors are moving back and force leveling the beach surface destroying the sand castles and burying butts and seaweed. All of a sudden, one of the tractor’s wheels got stuck in the sand.
The driver started angrily push the pedal or whatever else there is to push, making the tractor move back and forth slowly but surely getting deeper and deeper into the sand. When the tractor’s belly was literally laying on the sand, the driver realized that he won’t be able to get the vehicle out of the sand himself.
I was observing the entire show from the beginning of submerging till the moment he started to call for help using his cell phone. This is when I took the picture. What struck me the most was that during all this time the driver didn’t even bother to step down from the tractor to do anything manually to prevent the submerging. He didn’t bother and he was not trained for these kinds of situations. I assume he was told to call the office in case of any extraordinary situations. Houston, we got a problem!
Do you see the analogy with a framework coder who doesn’t know how things work under the hood? I clearly do. I also know that among the tractor drivers that are working on that beach there are people who know how to fix these situations without calling for a tow truck.
On the same note, each team of programmers includes a person who knows how to fix everything starting from fine tuning SQL all the way to fixing broken builds or writing manual piece of code that performs better than a framework.
Some developers who use open source frameworks know that if there is a bug in the framework or some feature doesn’t exist they file the bug or request for improvement with the vendor and then happily report to their managers that we have to wait till the vendor will fix it. But there are people who understand the words “open source” literally. Yep, they open the sources, read the code, subclass the problematic classes and make the fixes on their own.
The question is if IT managers understand and promote those people who are not afraid to roll out the sleeves. It helps if the software developers know how to manage the manager. But this is a topic for another blog.

Everyone talks about continuous integration and continuous delivery but those are just two ends of the pipeline. In the middle of DevOps is continuous testing (CT), and many organizations are struggling to implement continuous testing effectively. After all, without continuous testing there is no delivery. And Lab-As-A-Service (LaaS) enhances the CT with dynamic on-demand self-serve test topologies. CT together with LAAS make a powerful combination that perfectly serves complex software developm...

The Internet of Things is in the early stages of mainstream deployment but it promises to unlock value and rapidly transform how organizations manage, operationalize, and monetize their assets. IoT is a complex structure of hardware, sensors, applications, analytics and devices that need to be able to communicate geographically and across all functions. Once the data is collected from numerous endpoints, the challenge then becomes converting it into actionable insight.

Enterprises can achieve rigorous IT security as well as improved DevOps practices and Cloud economics by taking a new, cloud-native approach to application delivery. Because the attack surface for cloud applications is dramatically different than for highly controlled data centers, a disciplined and multi-layered approach that spans all of your processes, staff, vendors and technologies is required. This may sound expensive and time consuming to achieve as you plan how to move selected applicati...

Consumer IoT applications provide data about the user that just doesn’t exist in traditional PC or mobile web applications. This rich data, or “context,” enables the highly personalized consumer experiences that characterize many consumer IoT apps. This same data is also providing brands with unprecedented insight into how their connected products are being used, while, at the same time, powering highly targeted engagement and marketing opportunities. In his session at @ThingsExpo, Nathan Trel...
