BLOG: Scrum smells

Signs of something may be amiss on the scrum project:

1. Loss of rhythm.
2. Talking chickens those involved but not committed. Not allowing chicken to talk during the daily meeting is one of the Scrum’s simple rules.

3. Missing pigs those committed to the project. When run well the daily Scrum should always never exceed fifteen minutes and will always be of value to each pig.

4. Persistence signatures.
5. ScrumMaster assigns work.
6. The daily scrum is for the master. The first purpose of the daily scrum is to provide a coordination mechanism for everyone on the project. The other purpose of the daily Scrum is for each team member to make commitment in front of his or her peers.

7. Specialized job roles. Scrum team need to have a “we’re al lin this together attitude.” This can sometimes be undermined if a team has specialized job descriptions or roles.

I am cool on the other way. And here is the other way to think about.

Learn

Perfect

Transcend

People don’t like crisis and anxieties. People do things to avoid it instead of dealing with it.

BLOG: Beyond Agile Software Development: Becoming Lean.

Lean thinking has had a dramatic effect on industries from manufacturing to banking to hospitals. In software development, lean principles lead us inevitably to agile software develop – and beyond. Lean is not just about iterative development. It is about transforming customer needs into deployed software rapidly, reliably, and repeatedly.

Lean is not about slowing down and being careful, it’s about catching errors the moment they occur so that you can reliably go fast.

QA is not responsible for finding defects versus preventing them from happening.

Agile doesn’t emphasize speed. Scrum only helps dysfunctional organization.

In queueing theory, Little's result, theorem, or law says: The average number of customers in a stable system (over some time interval) is equal to their average arrival rate, multiplied by their average time in the system. Assume customers arrive at the rate of 10 per hour and stay an average of 0.5 hour. This means we should find the average number of customers in the store at any time to be 5.

Performance is the cycle time how fast the customer needs can be repeatedly convert into the deployed software. Productivity is not how many lines you can write or how many features you can produce over a period of time.

Build only what you need.

Stop when something goes wrong.

Eliminate the waste. (Decide as late as possible. Reduce to-do list. No queues. Small batch. Build quality.)

Amplify the learning.

Optimize as a whole.

Build defects-proof system process, continuous integration and synchronization.

BLOG: Text Converting and Intall IIS virtual directory

System.Convert.ToBase64String

System.Convert.FromBase64String

System.Text.Encoding.UTF8.GetBytes(string).

net stop w3svc

net stop iisadmin

Few people realize that files with the .ashx extension are HTTP handlers as well.

How to create the virtual directory in IIS

string strSchema = "IIsWebVirtualDir";

string strRootSubPath = "/W3SVC/1/Root";

DirectoryEntry deRoot = new DirectoryEntry("IIS://" + server + strRootSubPath);

BLOG: MS SQL Server 2005 Express Edition Requirement:

MS SQL Server 2005 Express Edition Requirement:

Installer SQLEXPR.exe 54M free space.

Require 600MB free space.

- We recommend against running SQL Server Express on a domain controller. it cannot run on a Windows Server 2003 domain controller as Local Service or Network Service

- 2003 Server SP 1 (MSI-3.0)

- Frameworks .NET 2.0 (You could go to %WINDIR%\Microsoft.NET\Framework\ to verify your version).

- To enable the Windows CSP service on Windows Server 2003. (Cryptographic Service Provider)

- MSDTC Is Fully Enabled on Windows

In Control Panel, open Administrative Tools, and then double-click Component Services.

In the left pane of Console Root, click Component Services, and then expand Computers.

Right-click My Computer, and then click Properties.

On the MSDTC tab, click Security Configuration.

Under Security Settings, select all of the check boxes.

Verify that the DTC Logon Account name is set to NT AUTHORITY\NetworkService.

- It install the SQL Native Client and Setup Support Files, MSXML6, SQL VSS Writer, SQL Server Database Services;, Books online.

- Choose Named Instance “SQLExpress”

- Service Account “Local System” probably no network access.

Specifies a domain user account that uses Windows Authentication to set up and connect to SQL Server. Microsoft recommends using a domain user account with minimal rights for the SQL Server service, as the SQL Server service does not require administrator account privileges. The SQL Server Agent account must have administrator privileges if you create CmdExec and ActiveScript jobs that belong to someone other than a SQL Server administrator, or if you use the AutoRestart feature. If the above features are requirements in your environment, consider using separate service accounts for the SQL Server and SQL Server Agent services.

- sa has to be protected with strong password “Avocent456”

- You have to use SQL Server 2005 Surface Area Configuration to open the connection.
- You also need to go to the SQL Server Configuration Manager to set the TCP port to 1433 instead of other value.
-

After you install SQL Server Express, use the following command to connect to SQL Server Express by using the command prompt:

$sqlcmd -S Server\Instance (Kira\SQLExpress)

You could also upgrade from Microsoft SQL Server 2000 Desktop Edition to Express Edition.
