Following are some guidelines

2011-04-27T04:57:00.000-07:00

Guidelines for Software Architect

1. Do not drive the architecture from the structure of the use cases. Instead, use domain experts and object modeling to identify the key business abstractions.
2. Identifying Software Components i.e. distribution, concurrency, layering, cohesion, and coupling.
3. Identify and manage non-functional requirements.
4. Take owner of the proposed Architecture and guide the team members during the implementation.
5. Undertake the technical leadership to ensure everything is taken care of and that the team is being steered in the right direction on a continuous basis.
6. Ensure that all business processes are coded inside business tier.
7. Update class diagram for every project even for a small change. Changes should be highlighted in the diagram
8. Activity , sequence and collaboration diagram will be created if approved by Management
9. All the architectural, design and specification changes to the system will be made by the approval of Software Architect.
10. ERD will be created or updated if a new table or data field changes
11. Best practices and pattern should be used for both .net and sql
12. Perform code review on weekly basis.
13. Proper Naming convention should be used for all .net and SQL related code
14. All classes, method and functions should get approved by Software Architect

Formatting and documenting your regex

2010-01-17T21:57:00.000-08:00

Regular expressions are a very powerful tool for pattern matching, but a complicated
regex can be very difficult for a human to read and to comprehend. That is why,
like any good code, a good regular expression must be well formatted and documented.

Here are some guidelines when formatting and documenting your regex:

1. Keep each line under 80 characters, horizontal scrolling reduces readability.
2. Break long patterns into multiple lines, usually after a space or a line break.
3. Indent bracers to help think in the right scope.
4. Format complicated OR patterns into multiple blocks like a case statement.
5. Comment your regex on what it does, don't just translate it into English.

# Match <BODY
<BODY
# Match any non > char for zero to infinite number of times
[^>]*
# MATCH >
>

Bad example: Comment that translates the regex into English.

# Match the BODY tag
<BODY
# Match any character in the body tag
[^>]*
# Match the end BODY tag
>

Good example: Comment that explains the purpose of the pattern.

(?six-mn:(LabelTextBox)\s+(?<Name>\w+).*(?<Result>\k<Name>\.TextAlign\s*=\s*
((System\.)?Drawing\.)?ContentAlignment\.(?! TopLeftMiddleLeftTopCenterMiddleCenter)\w*)(?!(?<=\k<Name>\.Image.*)(?
=.*\k<Name>\.Image)))

Bad Example: Pray you never have to modify this regex.

(?six-mn:

# Match for Label or TextBox control

# Store name into <name> group

(LabelTextBox)\s+(?<Name>\w+).*

# Match any non-standard TextAlign

# Store any match in Result group for error reporting in CA

(?<Result>

# Match for control's TextAlign Property

\k<Name>\.TextAlign\s*=\s*

# Match for possible namespace

((System\.)?Drawing\.)?ContentAlignment\.

# Match any ContentAlignment that is not in the group

(?!TopLeftMiddleLeftTopCenterMiddleCenter)\w*

)

# Skip any Control that has image on it
(?!
(?<=
\k<Name>\.Image
.*
)
(?=
.*
\k<Name>\.Image
)
)
)

Good Example: Now it make sense!

Skype and iPhone together at last - fring launches iPhone VoIP client and it also support Skype

There's been considerable talk about VoIP services one the iPhone. Fring started out as a mobile client for accessing Skype, though the application now links up to all types of networks including MSN, Google pTalk and AIM, thus allowing for an identity-aggregator for mobile use.

You can do chat/calls by using Skype (Fring) but unfortunately call only allow on WIFI network. But hacker worked on it and they deployed a tool that cheats Fring and you can easilt make calls on Edge or 3G network. It will be fantastic if you can use Fring with your data plan

You'll need:
1. Fring installed. You can download it on the App Store.
2. A jaibroken iPhone.
3. Cydia installed.

Launch Cydia and search for "VoIPover3G" and install them
Restart your iPhone, launch Fring and you should be able to use it over the Edge/3G

M.Box Mail: iPhone/IPod App for Hotmail and Windows Live Mail

2009-03-09T01:50:00.000-07:00

The Bottom Line

At last you can easily get you Hotmail on your Phone mBox Malls Is designed to help you get your Hotmail as you are used to getting you Hotmail. It Is Like the - native” or built-in mail application on the iPhone — only It speaks the Windows Live Hotmail protocol.

Finally, you can have your Hotmail messages and folders on your Phone.

mBox Mail works much like the iPhone's built-in Mail but talks to Windows Live Hotmail accounts and integrates your Windows Live contacts with your iPhone's, too.
Unfortunately, mBox Mail can only access one account.

Easy Startup
Just enter your Windows Live Hotmail address and your password to start using mBox Mail. You have the ability to choose how many email bodies are available on the device through easy-to-use mBox Mail settings found in the iPhone settings. This means you can view 25 messages or 200 at a time.

Pros
mBox Mail lets you access Windows Live Hotmail accounts on an iPhone
You can read and delete mail in all folders and send messages, too
mBox Mail integrates both iPhone and Windows Live contacts

Cons
mBox Mail can access only one Windows Live Hotmail account at a time
You cannot open messages larger than 1 MB directly in mBox Mail

Description
You can read, delete and send mail in portrait or landscape mode, open attachments and send images from Photos.

New mail can be announces with sound and vibration; mBox Mail can confirm sending with a sound, too.

mBox Mail uses both your iPhone and your Windows Live contacts to auto-complete addresses.
You can include a signature with mail you send from mBox Mail and send yourself a Bcc copy automatically.

mBox Mail supports iPhone and iPod touch 2.

Guide Review - mBox Mail 1.2 - Windows Live Hotmail Email Program for iPhone and iPod touch

You can access Windows Live Hotmail with your iPhone: use Safari, or channel Hotmail through an external service. It works, and it is clumsy.
How about an app that works just like iPhone Mail but talks to Windows Live Hotmail instead of POP and IMAP accounts? mBox Mail is that application. You can open any folder in your account and move messages freely (and in bulk to, say, mark them as such) just like in Mail. It's a pity mBox Mail can access only one account at a time, though.
What mBox Mail does very right is gathering contacts: not only does it use and auto-complete your iPhone addresses but those from Windows Live Hotmail as well. Composing messages, then, works much like it does in Mail — in a bit less straight-forward but in a functional manner none the less. You can even attach images from Photos and save drafts in mBox Mail, though they are not synced with Windows Live Hotmail.
For incoming emails exceeding 1 MB, you are directed to Windows Live Hotmail's web interface.

Thankfully, mBox Mail lets you read and type in both portrait and landscape mode, though.

Anti-Mosquito for iPhone

2009-03-03T00:35:00.000-08:00

Anti-Mosquito produces sound in the range of 16000hz to 20000hz that is beyond the audible range of humans.... but mosquitos are other harmful insects can hear it.

It keeps generating sounds while the device is locked or in sleep mode.

Overall I really liked this app, the only downside is for the animals, don’t leave your the app on with the maximum volume and your dog or cat right next to it; make them go in an other room. Overall, this is a really awesome app! I’ll give it a 4/5.
