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 […]
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.
Guess what – you are stuck with it. So you can chose to let the underlying system handle it or you can chose to dictate how your traffic should flow.
Do not let the illusion of control dictate the performance. Be the one who needs to control and manage the traffic
We sacrifice the art of writing good and performant code for the short term gains of improving developer productivity.
Annotations can be powerful but only when used to add context and information to the code. But trying to configure your application with them is nothing less that a crime.
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.
Use Annotations to anything is is core to the application and defines the core structure of the application. Anything that would need a code change is okay to sit as an annotation. Rest everything else should be XML.
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.
What I want to do here is to compare 3 workflows and see what each one has to offer and what’s the best possible way to remove this inefficiency or improve productivity.
1. Follow the current set of technologies JSP-Java but change the way of working aka different set of tools, trainings and processes
2. Use Sightly ~ the new templating language pushed by AEM
3. Use other templating languages like handlebars or angular which are more platform agnostic and goes beyond just CMS and AEM (old school application development also fits)
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.
If you ever have designed or want to design a platform/site that needs to support some steep non-functional requirements like 1Billion hits, then you have to rever to using cache as a key part of the framework. How cache as we have known it back in the days is not longer just plugging in a library and start writing to it. There is a lot more to it when we talk in context of a Digital Media platform and how you deal with very high loads. This article will talk about principles that will help you design for
– Performance: Caching is a pattern that we employ to increase the overall performance the application by storing the (processed) data in a store that is a) closest to the consumer of the data and b) is accessible quickly
– Scalability: In cases when we need to make the same data-set available to various consumers of the system, caching as a pattern makes it possible for us to scale the systems much better. Caching as we discussed earlier allows us to have processed data which takes away the need to run the same processing time and again which facilitates scalability
– Availability: Building on similar principles as of scalability, caching allows us to put in place data in areas where systems/components can survive outages be it network or other components. While it may lead to surfacing stale data at points, the systems are still available to the end users.
