Office Communicator 2007 - send message

2011-10-03T00:01:00.000-07:00

It would have been nice if there was a command line way of sending message from office communicator. Googled and did not found anything. Finally created a fragile scritp using WSHShell . It is fragile but it works and saves time for me.

option explicit

' Global variable to hold the initials and name mapping.
' Commandline may have initials in place of the name.
dim Names
Set Names = CreateObject("Scripting.Dictionary")
Names.Add "C1", "Contact1"
Names.Add "C2", "Contact2"
Names.Add "C3", "Contact3"

' Global variable used by mySendKeys function.
dim Wsh
set Wsh = Wscript.CreateObject("Wscript.Shell")

if (Wscript.Arguments.Count < 1) Then
    Wscript.Echo "Usage: m "
    Wscript.Quit(1)
End if

dim name
name = UCASE(Wscript.Arguments(0))
if (Names.Exists(name)) then
    name = Names.item(name)
end if

'Wscript.echo name

Wsh.Run       "communicator" ' Run communicator
Wscript.Sleep 500                     ' Give time for communicator to open.
mySendKeys    "{TAB}"           ' TAB
mySendKeys    "{DOWN}"       ' Down Arrow
mySendKeys    name                ' Search for the contact in my list.
Wscript.Sleep 500                     ' Wait for select to happen.
mySendKeys    "{ENTER}"      ' Enter
Wscript.Quit(0)                          ' Success

inetwiz automation

2011-09-27T06:58:00.001-07:00

inetwiz is a tool which I have been using in Windows XP to update the IE proxy setting.
The manual process has been a pain and I wanted to automate it badly.
Experimented with multiple tools - Registry updates, Python. A friend suggested to use VBS.
The VBS did the trick and I was able to use Wscript Run, AppActivate and sendKeys method to automate the proxy update and opening the URL in internet explorer.

Here is the script

option explicit

' Global variable used by mySendKeys function.

dim Wsh

set Wsh = Wscript.CreateObject("Wscript.Shell")

if (Wscript.Arguments.Count < 2) Then

Wscript.Echo "Usage: i /auto|/man URL"

Wscript.Quit(1)

End if

'WScript.Echo (Wsh.RegRead("HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable"))

if (Wscript.Arguments(0) = "/man") Then

' VB Script does not support double equal.

' If Proxy is not enabled, enable it.

if (Wsh.RegRead("HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable") = 0) Then

enableManProxy()

End if

Wsh.Run "iexplore " & Wscript.Arguments(1)

Elseif (Wscript.Arguments(0) = "/auto") Then

' If Auto Proxy is not enabled.

' VB Script does not support double equal.

if (Wsh.RegRead("HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ProxyEnable") = 1) Then

enableAutoProxy()

End if

Wsh.Run "iexplore " & Wscript.Arguments(1)

Else

Wscript.Echo "Usage: i /auto|/man URL"

End if

Function enableAutoProxy()

' Enable Automatic Proxy

Wsh.Run "inetwiz"

Wscript.Sleep 1000 ' Give time for application window to open.

End Function

Nested screen sessions

2011-09-11T00:43:00.000-07:00

I have been using GNU screens since few years but never thought of using nested screen SESSIONS. Nested screen sessions comes handy when you want to SSH to other server from screen WINDOWS. Here is my recipe for handling nested screen sessions.

* ssh jayrajput@serverA
* screen -e ^Ee # Change escape character from Ctrl-A to Ctrl-E. see escape function in man screen.
* screen -d -m -S serverA # Create a new detached screen session named "serverA" on serverA in detached mode.
* screen -x serverA # Attach to the "serverA" screen session.
* Ctrl-E + c # create a new screen window
* ssh jayrajput@serverB # ssh to serverB
* screen # Run screen on serverB

Use Ctrl-A as command leader in inner screen sessions .
User Ctrl-E as command leader in outer screen sessions.

Setting the hardstatus your .screenrc also comes handy

hardstatus alwayslastline
hardstatus string "%t"

This will show the hostname in the outer screen session status. Do not know why but it does show the hostname.

Continuous Ping

2011-01-04T12:21:00.000-08:00

ping -t

This is helpful when you do not want to open cmd window and execute ping command from the run prompt.

Learn to Live

2010-10-02T08:41:00.001-07:00

Learn to live, learn to let go & follow nature rule

I have always wondered at the almost robotic way we function. what’s the reason to continue a relationship or a venture when there is no emotion or heart in it? I see no reason to go on, if there is no emotion. One has to realise when to move on, when to let go. It’s best to live life as an honest free spirit and challenge those who infringe upon your joy. The conundrum of modern-day life has robbed us of compassion. We have been drained of love and humility. It’s good to remember that life is so easily destroyed, if we are not careful.

Dissatisfaction, sadness, hatred – these are the mind’s creations. You don’t need to serve your connection with the world, if you feel let down. To tackle that, it’s essential that you lead a normal life while trying to find out the root cause of dissatisfied mind. This approach is both realistic and practical and guarantees an answer to most of your deep-seated problems.

Being happy depends not so much on external circumstances as on your inner life. This means all your thoughts, perceptions, beliefs, emotions, desires, dreams – your entire mental and emotional scene. Happiness is about how you react inwardly to events, what you think and believe, how you feel, how problems affect you. It may sound obvious, but like many obvious things it’s something that is often forgotten when it matters most. We focus almost exclusively on or external lives, on getting and spending and having fun and then wonder why we are not happy. But it’s when our inner lives are tranquil that we are most happiest and we call this inner peace.

You can’t completely avoid problems, but you can change how you react to them by acquiring new habits that provoke peaceful inner responses. Training your inner life into different habits require learning skills of thinking, feeling and managing your beliefs and desires. These are very like the virtues many religions and philosophies advocate but if u think of them as skill rather than virtues, you benefit from an important and liberating shift. Instead of ‘ I must become a better person’ you can think ‘I would lie more happily if I work on my skills’. So the change in attitude becomes a choice, not a duty. This process is not something u can do overnight, it’s a whole new way of life but the reward is what we all want most – happiness. There are five main skills who need to cultivate.

Mindfulness:- this involves developing your ability to focus your thoughts in the present. The problem most of us have with thought is having too much of it – the working and non-stop mental chattering our minds are prone to. Mindfulness is a key in our skill because as it gets stronger, it lets you focus on your inner life and catch your habits in the act. Once you can see how u r rolled by them, the change u r seeking often happens of it’s own accord.

Compassion:- most religions rightly stress compassion. As well as being a virtue in its own right it is a practical skill that counter act negative emotions like anger and hatred, which are terrible wreckers of happiness. Tried the next time someone annoys you; put yourself what they might be thinking or feeling to behave like that. Even bad people, let alone people who just mildly annoy you, often have a mistaken view of the world which makes them do what they do.

Story skills:- these are very useful for problems with your inner belie system, as they let you stand back and explore alternative versions of reality. Believes have great power over your life because belief is something your take as fact. Start to think of your believes as stories and it is easier to accept that other things might be true as well. Even true stories only select a little bit of reality we are focusing on at the moment, no one story is the whole truth about any situation. From a different point of view we would see a different t story, sometimes a whole different world. This is not about make beliefs, its about reframing situations to look at them from a different perspective.

Letting – go techniques:- these are particularly helpful when we are unhappy not getting what we want. Generally, we are encouraged to keep wanting and to think that more will make us happier, whether its clothes or cars or even love. But wanting is a treadmill; as long as you have unsatisfied want and desires, or let go some of them. Letting-go skills also include forgiveness, which helps hugely with one of the things you think you want is revenge.

Enjoyment skills:- this last group includes skills such as patience humour and especially gratitude. You don’t have to be grateful to someone, it’s enough to cultivate gratitude or things. Our minds naturally scan the environment for dangers and resources, a useful mechanism when we were hunter-gathers. But it can make us unnecessarily pessimistic – focussing on 10% we lack rather than 90% we have cultivating enjoyment skills will help redress the balance.

Acquiring all his skills takes time and effort. The important thing is to practice them until they operate without you thinking about them. Your practice routine will be very individual because everyone needs to prioritise different skills depending on the specific issues that you are holding them back from being happy but keep the skills in mind and you will constantly find new ways to try them out.

Skype automation

Shell Standard I/O

2009-11-13T10:31:00.000-08:00

Q: What is the difference between these two shell statements?

$cmd >> $logFile 2>&1
And
$cmd 2>&1 >> $logFile

Answer:
The first one is right and second one is wrong.

first one redirects any output from the $cmd to the $logFile. The second one just redirects the output and not the STDERR to the $logFile.

Moral Dilemma

2009-11-01T21:01:00.000-08:00

Q: How to decide if an action is morally right or wrong? E.g.
1. Taking a personal prinout using office printer?
2. Making a phone call using office phone ?
3. Stealing salad from the salad bar at office canteen?
4. Keeping the IPOD nano 4 GB found on a street at halloween pary on franklin street with urself?

Ans: If you can tell all your friends and family members about the action then the action should be morally right.
1. Should be OK.
2. Should be OK.
3. WRONG.
4. Dicey.

2009-10-15T07:02:00.000-07:00

It is Democracy...So why not create own phrases, sentences and syndromes like others. So here is one from me:

Finish it syndrome.

The syndrome is one in which the DIET conscious person end up eating more in following scenario:
1. Person end up taking more cereal as he wanted to finish the contents of the cereal box. Why not use it next item it is not going to get perished.
2. Person end up taking more serving as he did not wanted the food to be wasted. Why not use the zip- lock bags..:-)

Motivation for fast running

2009-10-08T19:14:00.000-07:00

I always wanted to run fast but was never motivated. But then I found something which motivated me.

I read somewhere that running fast makes your abs and who does not want to have six pack abs.
Six pack abs are enough reason for me to be motivated for fast running.

VIM : Comments lines with a pattern in a file

2009-05-19T09:20:00.000-07:00

The lines in a file containing a specific pattern can be commented in VIM using the :g command.
:g command is used in following form
:g/[patern]/[cmd]

Example:
:g/JR/normal I //

explanation
Pattern : JR
Cmd : normal I //

"I" is used in VIM to start insert mode at the start of line and "//" is the comment character used in PHP.

Enjoy VIM. Check out the help :g if you have more questions.

Toggle Comment in VIM in one line using perl

2009-03-30T20:32:00.000-07:00

There are lot of scripts in VIM which can toggle comments for you. But interestingly there is not a one liner which I can execute on systems where I do not have my vimrc file.

try this mapping

:map F2 V:!perl -nle 'if (/^\s*\/\//) { s/\s*\/\/\s*(.*)/$1/g; print } else {print "//".$_}'^Mj

You can map Alt+C or Ctrl+T something which is faster than F2

This mapping will comment and uncomment the C-style comment. I have tried this on Ubuntu and VIM 7.1 and works fine for me

Note: The map command may not work on copying as the VIM may not recognize the Ctrl - M character. You have to Ctrl- V and then Enter to make it work

Singleton versus Static

2009-03-13T08:08:00.000-07:00

These are rules which I use to decide where or not my class will be a Singleton or Static:

Control over construction. Timing issues.
Polymorphism.
One versus multiple instances.

Formatting XML in VIM - xmllint --format -

2009-03-10T19:16:00.000-07:00

XML text can be formatted in VIM by running the xmllint command over the selected text.

!xmllint --format -

Note the hyphen at the last.

Tried searching for sorter options for --format but did not found any.

VNC not working on locked PC

2009-03-09T09:50:00.000-07:00

Problem:
---------
I found that the VNC was not working on my PC(Windows XP) when it was locked using Ctrl+Alt+Del. Interestingly it did worked when the PC was not locked.

Solution:
---------
While installing VNC make sure that you select the option to install it as a service so it can be seen in services.msc

On installing VNC, it provides an option to install as a service. If it is not installed as an service, the VNC cannot be done on a locked PC.

Reason:
--------
This is what as told by one of my colleagues. Seems to be logical.

Windows uses API from gina.dll which provides the capabilities for locking/unlocking the workstation. API from gina.dll are accessible only by the windows services and not by other programs.

timeout

2008-10-11T07:52:00.000-07:00

Debian has an interesting command timeout:

timeout 5 tail -f /var/log/messages

If you do not have timeout package installed, perl can be used to perform the same:

perl -e "alarm shift @ARGV; exec @ARGV;" 5 tail -f /var/log/messages

Ethtool - Finding the NIC to which the LAN cable is connected

2008-09-17T06:24:00.000-07:00

How to find if it is eth01, eth02, eth03 etc to which the LAN is connected.
Sometimes the PCI slots are not properly numbered and we cannot rely on the normal naming convention. Linux ethtool comes handy at that time to find the NIC card.

Use

ethtool -p

This will glow the light on the NIC card. You can just see the glowing the NIC and guess the name.

PHP Hacking 1 = 1

2008-05-23T14:09:00.000-07:00

'1 =1 ' is classic example of SQL injection attack. For the authentication some PHP GUI saves the user id and password in database. Generally a query something like this is used to validate the user given information:

SELECT * FROM users
WHERE user=''
AND passwd=''

A simple hacker like me ;-) can use SQL injection attack by specifying
User: Any
Password: OR 1 =1

This will allow me to give access to the site. Depending on the query you may need to try other variations like

Password: ') OR ('1=1')

The idea is to inject 1 =1 (which is true) in SQL statement such that the WHERE clause returns TRUE.

Happy Hacking...

Putty passwordless ssh

2008-05-08T16:40:00.000-07:00

putty accepts login and password as command line. So it can be easily used in batch to access machines without giving login and password.

putty host1 -l root -pw

I use it to the server which are build frequently. The problem with the server built frequently is that you cannot exchange keys as the keys will be deleted when the server is built again.

If you are using a linux box then sshpass can also be used for auto SSH.

Here is the batch script for windows lover

@echo off
if %1 == myserver goto myserver
goto default

:myserver
start C:\putty -ssh mercury -l -pw
exit

:default
start C:\putty -ssh %1 -l root -pw
exit

Vim Ctrl-r Ctrl-w

2008-05-08T16:34:00.000-07:00

Vim Ctrl-r Ctrl-w can be used to read the word under the cursor. It is useful if you want to edit files under the cursor.

:e \C-v \C-r \C-v\C-w \C-v

I know you can use gf to go the file. But just wanted to do it using one key.:-)

Bind command

2008-05-08T16:23:00.000-07:00

bind command can be used to bind your key strokes with the commands. I use it frequently to access my cleartool commands.

after editing a file using vi. You can check the difference with the predecessor or the version tree for the file using key-strokes Alt-d or Alt-t

bind -x '"\M-d"':'cleartool diff -pred -g -options "-b" $_ &'
bind -x '"\M-t"':'cleartool lsvtree -g $_ &'

Handy RPM commands

wdl

2008-02-07T09:13:00.000-08:00

GNU working directory list is an open source utlity to easily move between the working directories. You can even set CDPATH to move effectively between the directores. But take care setting CDPATH can also cause make command to fail, if you have a top-level make file which cd into sub-dirs and does a make.

Screen Command

2007-12-28T17:24:00.000-08:00

Unix Screen command is an indespensable command. Once you know it you cannot live without it. It is window manager. Just try it and you will find it mind blowing.

A new screen can be created using
screen.

Ctrl-A c - Create new window
Ctrl-A A - Name a window
Ctrl-A " - Show all windows.

Ctrl-A S split window.
Ctrl-A tab to move to the next window.

Putty Title

2007-12-28T17:04:00.001-08:00

Putty Title can be easily modified using the function wt.

wt ()
{
echo -n "^[]2;${@}^G"
# In all of these, ^[ is really the "escape" character.
# You put it into a file using vi, by typing control-V and then hitting the Escape key.
# Likewise, ^G is the control-G# character. Again, hit control-V
# then hit control-G
}
