Agile Story Estimation

Saturday, 28 May 2022 10:50

Agile story estimations can be done through the use of time or story points. The story points approach is popular and widely used by team because the story points are assigned to a story in the backlog as a measure of relative effort and complexity of that story. This blog post intent is not to teach the team to achieve perfect or accurate estimation, but to assist the team in achieving reliable velocity. With reliable velocity, the team can easily predict how long it would take to deliver a unit of work in the backlog. A unit of work could be a milestone or an epic.

Sunday, January 12, 2020 2:11 AM

The ability to understand and process natural language is regarded as one of the superiority of humans to computer. Humans if able to read and or possibly write, can readily comprehend written texts and make meanings out of the syllables, grammar, vocabulary and punctuation. Although, as simple and effortless as it might seem for humans, making meaning out of a simple text for computers requires a bit of rules, logic driven approach or machine training and adaptation.

Saturday, April 29, 2017 11:47 AM

Prior to the availability of Open XML SDK and other Excel libraries in . Net, manipulating Microsoft excel files from ASP.Net web applications was a daunting task. Open XML SDK makes it easy to manipulates documents that conforms to the Office Open XML file formats specifications with a trade-off of writing plenty lines of code. Similar to OpenXML, ClosedXML is another elegant library that further simplifies the process of reading and writing to excel files and hides the complexities involved, without need of dealing with XML documents.

Bulk insertion of data into database table is a big overhead in application development. An approach would be to insert the records into the table using a loop in the application, this round trip approach consumes network and CPU resources and as such is not recommended. Microsoft ADO.Net provides the SqlBulkCopy class that lets you efficiently bulk load a SQL Server table with data from another source, but bulk loading an Oracle table can be done through the use of Oracle Data Provider for .Net (ODP.Net).

Lambda Expression in Java SE 8

Friday, June 20, 2014 2:15 PM

Programmers using functional languages have been enjoying some constructs as closure, lambda expressions that are not readily available in object oriented languages. Coming from a C# background and now programming in Java one would notice a lot of similarities and differences in the two languages. I am not going to start any debate on which language is better, but I would in my opinion say programming in C# is kind of cool due to availability of programming constructs such as Lambda Expression and LINQ. Lambda expression was not part of earlier versions of Java and as such, passing method o

TDD made easy with ncrunch

A while ago I blogged about Test Driven Development, where I did some introduction to TDD.

Someone even said "You write twice as much code to get the same job done, the overhead involved kills?". I strongly believe testing your codes as you write them is more important than fixing bugs after you have deployed the application. And TDD can be real fun when you have the right tools to assist you. I have used ncrunch, a visual studio
