How you can help tsunami victims

While the government is still slow with publicising
details of how people can help those affected by tsunamis that hit south India
on Sunday morning, bloggers in India

and elsewhere seem to be doing their bit.

Some like this one, are educating potential donors and volunteers on the
options before them. Notably, it does not focus on India
alone.

According to messages posted on this site, Médecins
Sans Frontières is among the NGOs organising

volunteers, financial aid and experts for affeted
areas in Asia. Some individuals have also got into the
act.

The Bharatiya Janata
Party announced an Emergency Relief Fund for Indians affected by the tsunami,
in New Delhi on Tuesday. A central
committee has been appointed to oversee the operations. People who wish to
contribute can contact local BJP offices, which will send the material to the
party’s headquarters in Delhi.

Indian Americans too have started organising aid
efforts. The National Federation of India Organizations has already collected
about $10,000 from its charitable accounts and is aiming for $100,000. Those
wishing to send money toward relief efforts can do so to the following organisations:

1. Tamil Nadu Chief Minister’s Public Relief Fund
Prime Minister’s National Relief Fund

2. BAPS Care International

Memory Leaks in .NET applications and Some Tips To avoid them

Developers using .NET often make memory leak tracking a low
priority because the common language runtime takes care of garbage collection.
What few developers realize, however, is that their objects’ lifespans, along with their size and what other objects have
been instantiated, all affect how they are cleaned up. Depending on the
particular circumstances, these combinations can negatively affect performance,
especially over the lifetime of an application.

The tips for reducing the Memory
Leaks

1) As we all have heard many times from the experts –
Strings are very expensive in .Net and we have not done well in using them
sparingly.

a. Use the .ToString() method intelligently which creates a new instance of the
string.

b. Be aware of string comparisons,
especially when doing string insensitive comparisons. For example, do not do
“if ( string1.ToUpper() == string2.ToUpper() )” – this
creates 2 new strings. Instead – use the string.Compare

function.

c.Make
effective use of variables to prevent the re-creation of strings.

For example –

I have seen some code written by inexperienced programmers
such as:

If (! hashTable.Contains ( SomeGuidID.ToString() )

hashTable.Add (SomeGuidID.ToString(), 1)

What this line
effectively did was create 2 strings, when a string variable could have been
declared and the ToString() method called only once.

d.The
other case that I’ve seen is the use of concatenated strings to form a key for
a hash table. For example:

hashTable.Add( ID1.ToString() + ID2.ToString(), 1 )

This is again inefficient as strings are bigger (in Bytes)
than a string. A Guid is 24 bytes where as a Guid.ToString() string is
40. That is a 67% increase in size over what is needed If
you need a concatenated key for use in a hash table, you can create a small and
efficient in-line class to handle that.

2) Recursive functions – due to the way that the heap is
managed, apparently recursive functions are very expensive as well and should
be avoided. Always try to avoid recursive functions wherever possible and just
use loops.

3) Maintaining the data tables has proved a quite heavy on
memory (I guess when you think about it, it
effectively doubles the memory usage of the raw data). Use DataTables
in the sistuation only if the data changes very
rapidly.

More tips to come later……………………………

.NET Dotfuscator

The .NET.
platform realizes Microsoft’s vision for the next
paradigm in Windows computing: multiple programming languages interacting
harmoniously, sharing an enriched object-based framework, contained within a
common runtime engine, running using just-in-time compilation. Application
development for Windows has never been easier or more accessible.

The .NET architecture is
unprecedented in its degree of power and flexibility. Unfortunately, that
design inherently produces a problem for those trying to hide their program’s
intellectual property. One concept that Java and .NET mutually share is the use
of expressive file syntax for delivery of executable code: bytecode
in the case of Java, MSIL (Microsoft Intermediate Language) for .NET. Being
much higher-level than binary machine code, the intermediate files are laden
with identifiers and algorithms that are immediately observable and ultimately
understandable. After all, it is obviously difficult to make something easy to
understand, flexible and extendable while simultaneously hiding its crucial
details.

Reverse engineering of programs
may be a serious problem for many reasons. Competitors can steal intellectual
property or even reuse your code in their products. Hackers can violate
application security and publish trade secrets or even redistribute the
application with trojan code
present. The threat is real, and luckily, so is the solution.

In early 1997, Preemptive
Solutions, Inc. released DashO, a product to help
prevent reversed engineer for Java. Today, DashO is
still the de-facto standard for enterprise code protection and size reduction
in the Java world.

In early 2002, Preemptive
introduced Dotfuscator to solve this problem in the
.NET space. With all the experience, know-how, and patents from DashO, Dotfuscator has hit the
ground running to protect .NET programs. Microsoft has acknowledged Dotfuscator’s abilities and has included a lite version of Dotfuscator in
every copy of Visual Studio..NET..

The lite version is called the Community Edition and
it will provide developers with a great introduction to the benefits of
obfuscation.

Getting System Environment Values in .NET

  1. Sometimes it is necessary to get the system environment values such as mydocuments folder, Temp Directory, System Directory and so on. .NET Framework allows you to get these values.

  1. Add some labels and text boxes as shown below in the figure:

  1. Now we need to write some code for Button Click event as follows:

private void cmdGet_Click(object sender, System.EventArgs e)

{

txtMachineName.Text = System.Environment.MachineName;

txtOSVersion.Text = System.Environment.OSVersion.Platform.ToString() + " " + System.Environment.OSVersion.Version.Major.ToString();

txtUserDomain.Text = System.Environment.UserDomainName;

txtUserName.Text = System.Environment.UserName;

string[] strDrives = System.Environment.GetLogicalDrives();

string drives = null;

foreach(string str in strDrives )

{

drives = drives + str + " , ";

}

txtSystemDrives.Text = drives;

txtMyDocuments.Text = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);

txtSystemFolder.Text = System.Environment.SystemDirectory;

txtTemporaryFolder.Text = System.Environment.GetEnvironmentVariable("TEMP");

txtProgramFiles.Text = System.Environment.GetFolderPath(System.Environment.SpecialFolder.ProgramFiles);

}

  1. Run your program and test it out! You will get the important system environment values! That’s all for this Tutorial!
