React and Angular do not fit everywhere

Last few years have been fascinating with several front-end frameworks coming up. I am not going to compare them; neither am I going to talk about The Good or The Bad on them. The buzz words, the new technologies are so shiny that almost everyone I speak to today wants to work on the new stuff. And they also tend to believe that you can solve everything by just writing a front-end application, make some API calls and it’s done. The focus of this post will be that React, or Angular or Vue.js or anything similar is not one size fit all frameworks and Servers Side Code still has a place in this world.

The false security of Notifications

it’s like jumping into my car and every time i see the dashboard every light in there is brightly lighted up – to the point that one day i stop caring. eventually, someday something will fail – i just hope it’s not the day when I am driving to someplace in an emergency.

Most of our Notifications and alerting strategy is more than a brightly lit Dashboard. We cant any more tell what’s gonna fail when.

It’s a false hope we live with.

This part of my life is called “Chasing Quality”

We will see how this goes. But, for now the 5 rules for quality for me stand even today are:

– Deliver an artifact and ensure no one can find a defect;
– I can refactor the code knowing it won’t break anything;
– Code commits work like a charm and i can deliver code in environments quickly and with certainly;
– When I send this application to my dear friends in operation, they don’t hate and curse me;
– Quality meant, once my work is done it’s done

Making Thread Dumps Intelligent

When you have to spend hours and hours and mostly on night, weekends and your anniversaries you ask yourself what could I have done better during development to make this all go easy on me.

Thread Dumps are you best friend when a production application (Java) crashes and if you can enable it to tell you something about the application then thats something. Here I have explained how and have included a bunch of Java Code you can reuse.

High availability design

Of course, eventually with many fixes over time you will eradicate a lot of cases that led to failures but it would have taken you so long and the reputation that the brand holds do dear is already damaged. You can chose to design for High Availability or you can chose to be just like Indian Railways – always delayed and always cancelled – a perspective that will i don’t think will ever be fixed no matter what they do.

AEM Development Workflow – Part 3 (Coding Old School)

The journey was nothing but painful all along the way. It took me 5 hours to do what should have been a few minutes job. The Site developer had the code up and running in a HTML file in a browser and all I had to do was to make it work “as is” within CQ. It seemed like the Force of Nature were working against me and everything I did, had a problem in it. I finally got it up and running (the designs done match off as is still), but it was excruciating pain.

AEM Development Workflow – Part 2 (finding the problem)

The AEM workflow problem is not really an inefficiency in the handover of HTMLs to CQ developers but how we should have been writing the code to begin with. We start here by seeing where the problem starts and how the code has been written. Unfortunately, we do see the OOTB Code in AEM as provided by Adobe itself are not coded to solve the problem. When I speak with Adobe they make it clear that these are reference sites and are to used as “Self-learning” but little did they know at the time that people will take this a practice and convert this into a culture.

Tip: Using AEM Developer Tools for Eclipse

This is a key step, and unless you get all those dependencies and if your project is brand new your project will not compile. If you are using an existing project it may just work if you have added those dependencies, but from experience as we dont compile JSPs those dependencies will not kick in. The code still works on CQ server because those dependencies are available at runtime.

(Unit Testing) – Cost vs. Benefit

In the current world of marketing, where we have clients who want to run campaigns in next 2 weeks, we can’t be slow in how soon we release code. You can only be relevant in the industry if you can move quickly, achieve the Continuous Delivery or at least reach a point when you can get releases out in production with a reasonable speed. Those days where releases used to happen once every 6 months are gone; or at least gone in the environment/market I am operating.

We have to have Self Testing Code, We have to Unit Test, We have to have feedback loops and We have to have feedback loop as soon as possible. There is no avoidance; let’s understand and embrace Or be extinct in a few years.

Unit Testing – Why not?

Not doing Unit Testing (again not saying “automated”), is like someone telling me – Kapil, you are driving to go to your wedding and you are late and now you have to drive faster. But, instead of putting in a few more airbags and giving you better set of wheels, better brakes; We are going to take the 1 Air Bag you have today and also replace your wheels with an older set. Now, go drive else you will not get married. What do you think I would do – Drive faster and risk my life or start driving even slower because I hope that my would be wife loves enough to know that I had no option but to drive slowly. Well you get the point – While I may get married, She is going to stay mad at me for a very long time for ruining her perfect day.

Thick Clients and CMS

Can a technology like Angular be used in the world of a CMS to solve the process problems where it just takes too long to get HTMLs from Site Developers into CQ’s templates and that too with a degree of quality that we are expected to deliver. This article lays down the foundation of what the challenges are and how it has started to impact our day to day life. The answer is not that simple, but at the looks of it, it seems we are using a technology to solve for a problem which is actually a people or a process problem. You can of course introduce a new component in the mix, but I still believe until people are ready to change, this new component wont do shit.

Unit Testing Framework: EAMSteps

EAMSteps is a framework that makes Unit Testing easier because of its following principles: – External data store for test data like excel spreadsheet – Automated assertions using co-related inputs and outputs – Minimal lines of code to get started It all started in 2009, when I decided that in long term I would need…
