Last week I met a modern language programmer...
Posted: Nov 30, 2013 10:51 AM
I don't want to start another language war so I just want to tell what happened, and hope EMB make more investments to make delphi more known to developers.

A young fellow programmer wrote a routine to import a text file. A set of 18 files will be downloaded every day from a BI system and each has several MBytes.
It took his code a few hours to import.. 10 hours to be precise. The code I wrote took a little over 10min. This made some unexpected noise in the company and the project planned to be written on that modern language might be reviewed and wrote in Delphi. Go figure!

They did some improvements on their code. After 2 hours optimizing ( 12 developers ), It took them 8 hours to import one file. :)
As a side note I'm sure they are not using the modern language as they should. But the fact is a company paid 12 developers for an 8 hours import of just ONE file. My application imported the 18 files in 1h25m with all the validations done ( as their routine also did )


The point is : neither the 12 young developers nor the product manager knew delphi could deliver such performance on such short schedule. They "heard" delphi shouldn't be used for such systems. And when I asked them what delphi was good for, they didn't know. So they never would use delphi to write anything :/

OBS: I wrote the code in XE5.

請大家告訴大家, 薑是老的辣 ! Delphi XE5 Go!
