QVGA in Mobiles

Now-a-days, we can see mobiles with QVGA displays which are more
attractive and soothing to our eyes.

When seeing the word "QVGA" everybody will be eager to know what it is
and to learn about it more.

QVGA stands for "Quarter Video Graphics Array".

Most often the displays are in a "portrait" alignment and are referred
to as 240 × 320 as the displays are taller than they are wide.

The name is derived from the fact that it offers 1/4 of the 640 × 480
maximum resolution of the original IBM VGA display technology, which
became a de facto industry standard in the late 1980s.

QVGA works typically with 15-30 frames per second.

At higher resolutions the "Q" prefix sometimes means "Quad" or four
times the display resolution (e.g. QXGA which is 2048 × 1536).

Security Settings to Audit Active Directory

5 of the more important security settings that need to be audited to protect your computers at the highest level.

To discover incorrect security settings, some key security settings to be audited for Windows Active Directory enterprise.

5 of the more important security settings that need to be audited to protect your investment at the highest level.

Windows Active Directory Security:

Standard attacks launched on Windows environments which these security settings can help protect against, if configured correctly.

1. Password Policies:

Password policies for an Active Directory domain are initially configured in the Default Domain Policy Group Policy Object (GPO).

Check with your security policies to determine what these values have been set to for your enterprise. If you have not set, here are some recommended values:

Password Policy Setting	Recommended Value Range
Enforce password history	12 to 24 passwords remembered
Maximum password age	30 to 90 days
Minimum password age	1 to 3 days
Minimum password length	7 to 14 characters
Password must meet complexity requirements	Enabled
Store password using reversible encryption	Disabled

2. Account Lockout Policy:

Account lockout policy controls what happens when a user fails to remember their password.

Following table illustrates some best practice values for these settings:

Account Lockout Policy Setting	Recommended value range
Account lockout duration	9999 (this can also be set to a lower number, such as 5, but should never be 0)
Account lockout threshold	3 to 5
Reset account lockout counter after	9999

Settings are stored in the Default Domain Policy GPO, a tool such as DUMPSEC or a domain controllers’ Local Security Policy should be analyzed.

3. Enterprise Admin Group Membership:

Members of the Enterprise Admins are an essential group for an Active directory enterprise. Members of this group can perform global changes to “enterprise” type of functions.

Members of this group also have control over all user accounts, group accounts, and computer accounts in entire domain.

To audit this group, need to check in one domain Active Directory forest. This group should be limited to only a few administrators. I suggest this group has no members on a daily basis.

DUMPSEC does an excellent job of auditing this group. Also, use the Active Directory Users and Computers to view groups and users that have membership in this group.

4. Schema Admins Group Membership:

Admins group can modify the Active Directory schema, which affects all domains in the forest.

This group can have no members on a daily basis. By limiting the members, or eliminating them, changes can be better managed and controlled.

5. Domain Admins Group Membership:

The one group that has global control over all users, groups, and computers in a single domain is the Domain Admins group. This group is very powerful and used on a daily basis. The members of this group should also be limited, but typically not empty.

ClearType Tuner for Windows

Microsoft also provides download for ClearType Tuner Powe Toy.

You can also download it from Softpedia.

Once the ClearType Tuner is installed, you can see that in Control Panel and run the wizard. Microsoft also provides online ClearType Tuner.

Here are the steps to enable the normal ClearType in Windows XP:
