Architecting scrum


Thoughts on Engineering Design and Analysis phase, specific to running sprints. Thoughts are based on assumption that PO is ready with sprint items.
I. Pre-requisites:
-     Understanding sprint requirements:
  • New User Stories
    • Story Specifications Walk through (PO, QA, Dev)
    • Understanding Acceptance Criteria
    • Wireframes walkthrough (where available)
  • Gathering performance and security requirements
  • Walk through of issues to be resolved in sprint and their priorities

II. Architecting Process
 -     Technical Impact Analysis (Very Important for running sprints) – Identifying impact on existing application against implementation thought for new stories/issues 
-       Planning implementation of any technical change in process/technology based on previous sprint review, retrospective meetings or any feedback from client
-       Decision Analysis & Resolution – Identifying the need for following based on sprint requirements and alternatives evaluation using a comparative matrix:
  • New Tools
  • New Libraries required – Paid/ Open-Source
  • Major Framework Level Changes
-     Planning Technical tasks
  • Breaking of user story into concrete technical tasks
  • Estimating tasks using Planning Poker or any other estimation tool
-      Preparing Support Documents – Level of documentation is subject to preferences as laid by client. (Personally, I rarely  see much documentation happening in running sprints)
  • High Level Design
    • Logical Entity diagrams
    • DFD/Flowcharts
    • Proof of concept where a new library/framework is applied
    • Test cases
  • LLD
    • Component level diagrams
    • Physical ER diagrams

How to construct a B+ tree with example

Image
A B+ tree contains n-1 search key values K1K2…….Kn-1 and have n pointers.   In a B+ tree the data are ordered  sequentially.  The leaf node may hold up to n pointers and must hold at least N/2 pointers. The root node must hold at least two pointers, unless the tree consists of only one node.  Now we construct a B+ tree. Construct a B+ tree for the following set of key values: (2,3,5,7,11,17,19,23,29,31) Assume that the tree is initially empty and values are added in ascending order. Construct a B+ tree where the pointer number is Four. Solution: When a node exceeds n-1 search key value then we split it into two nodes. First node contains (ceiling(n-1)/2) values.  2 nd node contains remaining node. Copy the smallest search key value of the second node to the parent node. Let's start, we know each node has N pointer and has N-1 search key values. In our example pointer number is 4, so the search key value is 4-1=3. So each node has 4 pointers and 3 search key value. The first node i

How to show only month and year fields in android Date-picker?

Image
Android default DatePicker show day/month/year fields but you have to customize this DatePicker as your requirements. Suppose that you want to show only month and year fields in android datepicker . To do this, you have to customize the Dialog DatePicker source code but it is not an easy task. In this tutorial I will show you a tricky way to solve this problem. Lets see how to show only month and year field in android DatePicker as a dialog.   Step to show only month and year fields in android date-picker: Some days ago I got this same problem and here I am trying to explain this in a sequential manner. I want to show a dialog datepicker when user click on an EditText. So if user click on EditText, A dialog datepicker will be invocked and it will show only month and year fields. To do this, at first we have to create a xml layout to hold the EditText fields. So create an android project and name it DatePickerExample. In the main.xml file just try to write this simple code.  main.xml

Visitor Counter Script Using PHP

Image
If you have noticed that many websites display their total numbers of visitors.In this tutorial I am going to explain you how to create a simple visitor counter using php. For this, 1) Create one table called “visitor_counter” in your database. 2) Create file named “counter.php”. Step1: Creating “visitor_counter” Table CREATE TABLE `visitor_counter` ( `counts` int(10) NOT NULL default '0' ) Step2: Creating “counter.php” File <?php  // Database Details $host="localhost"; $username="root"; $password=""; $db_name="test"; $tbl_name="visitor_counter"; // Connect to server and select database. mysql_connect("$host", "$username", "$password")or die("cannot connect to server "); mysql_select_db("$db_name")or die("cannot select DB");  $sql="SELECT * FROM $tbl_name"; $result=mysql_query($sql); $rows=mysql_fetch_array($result); $counter=$rows['counts']; // se
