Ambiguity in Technical Terms

It's been 3 years and 5 months since I started my professional journey. And I've noticed one thing from the very beginning. And that is the ambiguity surrounding the different terms in the industry. From the very basic terms to the more abstract. 

You will find people use Instantiation to mean Initialization and vice varca. Some will mean architechture diagram, but say data flow diagram. Some will confuse the external entity sign from data flow diagram to mean it somehow represents one to many or many to many relationship. 

I think in the abstract level, it means very little. Each team will have their own lingo and their own catchphrases but at the more root level it just gets confusing. Specially for someone who's just coming out of academia. 

One of the reason of these ambiguties I think is just our language. Bangla(or any other language other than English) is not really suitable to describe or explain programming or system design terminolgies. Because these terminologies have transcended any language and their native meaning. We all translate a term in bangla in our head to make the fog clear. But in the process of clearing up the concept, we confuse the terminologies. In the more abstract level however, I believe a lot of the companies or teams have their own systems which amalgated from different basic things and doesn't really matter on the long run(If you are involved enough in the initial SDLC phases).

Spring Data Jpa: What's underneath

Image
Spring Data in Spring Boot ( spring-boot-starter-data-jpa ) simplifies data access by abstracting the persistence layer and automatically implementing common repository patterns using JPA (typically Hibernate). This article is my attempt to go through what runs underneath and what boilerplate indeed spring data abstracts way for us. To make things easier I divided the demonstration in 3 parts 1. Make our own Data Access layer the old fashioned way with spring+hibernate. 2. Duplicate the same Data Access layer using spring boot. 3. How they both relate and how spring boot helps.   1. The Spring+Hibernate way The plane spring/hibernate way starts much like spring-boot way, that is with an entity layer.                                                ...

Postgres 18 Upgrades

The official Postgres documentation is in my opinion the most succinct documentation ever. It’s one of the list of things that got me interested in postgres as my defacto RDB of choice. I am always on the lookout for new additions to postgres. There's details on the enhancements on the upcoming version 18 here . I made this list of improvements on the upcoming Postgres 18 release that seemed interesting (or things amongst my realm of understanding). I thought It would be nice to share without going into too much technical details: 1. Async I/O Current Capability : PostgreSQL traditionally uses background processes like WAL writer, Checkpointer to help batch I/O tasks, but all these are synchronous under the hood. This can lead to higher latency, especially under heavy load. There’s no built-in native async I/O like you might find in some modern databases. Postgres 18 : Azure OSS team have now introduced true async on all read streams. In future this will inevitably lead to writes ...

It's been cloudy all day. Actual rain clouds, not one of those generic fluffy ones that aimlessly float around.I think they are called Cumulus or whatever. Saw a really pretty patch of bright blue on the way back home. So the blue was hidden away over a Cumulus, then two different dark layers of stratus clouds maybe. I've tried to study different types of clouds before, but it's just so difficult to identify.  The blue patch made me think how huge those clouds must be. Like a thousand or millions of kilograms of molecules just speeding through space. Chaotic order at it's finest I guess.
