Mercurial & hg view

Posted by admin under Linuxi:

Install on Ubuntu and Debian:  sudo apt-get install mercurial

hg view How?

You try the ‘hg view’ command and you will get an error:

sudo apt-get install mercurial
sudo apt-get install python-setuptools python-dev build-essential
sudo easy_install -U mercurial
wget http://www.selenic.com/mercurial/release/mercurial-1.0.tar.gz
tar zxvf mercurial-x.x.tar.gz
cp mercurial-x.x/contrib/hgk /usr/bin
sudo apt-get install tk8.5

put the following in your $HOME/.hgrc

[extensions]
hgk=/usr/local/lib/python2.6/dist-packages/mercurial-1.5.1-py2.6-linux-i686.egg/hgext/hgk.py

[hgk]
path=/your home/bin/hgk

Some Useful Commands:

The actual version information: hg version
Create a new repository in the given directory:hg help init
hg init [-e CMD] [--remotecmd CMD] [DEST]

Making a local copy of a repository: hg clone <directory>
or hg clone ssh://sourceforge.foo:port/removeDirectory

Through history: hg log or hg glog

Viewing specific revisions use the -r (or --rev) option
hg log -r 024584ws345
hg log -r q272e0d5w32 -r 0272e0d5w324

More detailed information add -v (or --verbose) option
To see content of a change add the -p (or --patch) option
e.g. hg log -v -p -l 9 | less

To display the change set: hg tip -vp
pull the changes: hg in, hg pull
update the working copy: hg up (update)

merging the changes

incoming change: hg in -v
outgoing change: hg out -v
hg merge -r default (tip)

The life of a patch

hg qnew -f <file-name> (create a new patch)
hg qimport fileName (import a patch file)
hg qseries -v (listen patches views)
hg qpop (remove the top patch) and hg qpop -a (for unapply all patches)
hg qpush (apply the patch again form the top) and hg qpush -a (apply all patches)

Specify a patch by name:
hg qpop -n <patch name>hg qpush -n <patch name>
hg qren (for rename a patch)
hg qrm <patch name> (remove patch)
hg qrefresh -U -e (check out the latest update of the patches)

hg log -v -r tip (Control)
hg qdiff | less -S
hg qrefresh -X foo (to exclude files matching foo)

Merge the changes from first-patch into second-patch
hg qgoto first-patch # go to first patch
hg qfold second-patch # fold second patch into it

Check For Email pattern

Posted by admin under Linuxi:

check for email pattern

if( !preg_match( “/^(([^<>()[\]\\\\.,;:\s@\”]+(\.[^<>()[\]\\\\.,;:\s@\”]+)*)|(\”([^\"\\\\\r]|(\\\\[\w\W]))*\”))@((\[([0-9]{1,3}\.){3}[0-9]{1,3}\])|(([a-z\-0-9áàäçéèêñóòôöüæøå]+\.)+[a-z]{2,}))$/i”, $email ) ) {
$msg = ‘Email address was not recognized as a valid email pattern’;
}

get the mx host name

if( preg_match( “/@\[[\d.]*\]$/”, $email ) ) {
$mxHost[0] = preg_replace( “/[\w\W]*@\[([\d.]+)\]$/”, “$1″, $email );
$msg = ‘Email address contained IP address ‘.$mxHost[0].’ – no need for MX lookup’;
// get all mx servers – if no MX records, assume domain is MX (SMTP RFC)
$domain = preg_replace( “/^[\w\W]*@([^@]*)$/i”, “$1″, $email );
if( !getmxrr( $domain, $mxHost, $weightings ) ) { $mxHost[0] = $domain;
$msg = ‘Failed to obtain MX records, defaulting to ‘.$domain.’ as specified by SMTP protocol’;
}

Clean up the Ubuntu

Posted by admin under Linuxi:

Install the Debian menu to make all installed applications

Missing Icons & Fix Broken Icons

sudo apt-get update
sudo apt-get install menu menu-xdg
update-menus

Keeping Ubuntu clean

Install deborphan with command:
sudo apt-get install deborphan

To delete unnecessary libraries just execute:
sudo deborphan | xargs sudo apt-get -y remove --purge

To delete unnecessary data

To see all

There is another tool to delete orphaned

Once it’s installed go to System –> Administration –> Remove Orphaned

Another nice tip is to clean partial and orphaned

increase the screen resolutions

Posted by admin under Linuxi:

Enter in root terminal:
$ sudo dpkg-reconfigure -phigh xserver-xorg

Select your video card by scroll up or down keys on your keyboard) and then hit enter.
the next select the resolutions that you would like to be available for Ubuntu by using the arrow keys to scroll up and down, and the Space Bar to select them.

Restart X by clicking Control+Alt+Delete (backspace). to set up new resolutions.

This starts the Xorg config process.

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup
sudo dpkg-reconfigure xserver-xorg
sudo xinit — :2

Look for errors:

tail -f /var/log/Xorg.0.log

Restart all servers by bouncing XDM (or gdm or kdm):

sudo /etc/init.d/xdm start

This starts a new X server — usually on tty8 or tty9 (CTRL-ALT-F8). You can go back to the original X server by pressing CTRL-ALT-F7.

Java Tips

Posted by admin under Linuxi:

Convert Map to ArrayList:
Map hashmap = new HashMap () ;
hashmap.put ( “one”,new Integer (1) ) ;
hashmap.put ( “two”,null ) ;
hashmap.put ( “three”, new String (“THREE”) ) ;

aList = new ArrayList ( hashmap.values () ) ;

System.out.println ( “The size of HashMap = “+hashmap.size () ) ;
System.out.println ( “If hashmap empty = “+hashmap.isEmpty () ) ;
System.out.println ( “The value for the \”three\” key =”+hashmap.get (“three”) ) ;
hashmap.remove ( “two” ) ;

Set set= hashmap.keySet () ;
Iterator iter = set.iterator () ;
int i=1;
while ( iter.hasNext () ) {
System.out.println ( ” “+i+” ) “+hashmap.get ( iter.next () ) ) ;
i++;
}

OR:
for (Iterator iter = hashmap.keySet().iterator(); iter.hasNext();)
{
KeyType element = (KeyType) iter.next();
ValType value = (ValType)hashmap.get(element);
}

hashmap.clear () ;

Use for-each loop through Map entry set:
Map hashmap = new HashMap () ;
for ( Map.Entry pair : hashmap )
{
System.out.println ( pair.getKey () + ” :: ” + pair.getValue () ) ;
}

Use ArrayList:
ArrayList arraylist = new ArrayList () ;

arraylist.add ( “india”,”", new String(“three”),null,”new Integer (1) ” ) ;
arraylist.add ( new Float (3.5) ) ;
arraylist.add ( 1,dummy ) ;

Add array Elements to the arraylist:
String array [] = { “foo”,”",”tow”,null,”new Integer (1) ” } ;
for ( int i=0;i < array.length;i++ )
{
arraylist.add ( i,array [i] ) ;
}

for ( int i=0;i < arraylist.size () ;i++ )
{
System.out.println ( ” “+ ( i+1 ) +” ) “+arraylist.get ( i ) ) ;
}

System.out.println ( “The size of arraylist =”+arraylist.size () ) ;
System.out.println ( “The arraylist is Empty? =”+arraylist.isEmpty () ) ;

Set the element at position one:
arraylist.set ( 1,”J2EE Programmer” ) ;

Converts arraylist to array:
Object array [] = arraylist.toArray () ;

for ( int i=0;i < array.length;i++ )
{
System.out.println ( ” “+ ( i+1 ) +” ) “+ array [ i ] ) ;
}

String value = “FOO”;
if ( “FOO”.equals(value) ) {
// do something
}

substring in Java
returnString = (xmlString.substring(xmlString.indexOf(“<ns1:queryReference>”) + 20, xmlString.indexOf(“</ns1:queryReference>”)));

The best ways to run all files from a folder in SqlPLus
Create a file and store all of the file names from the folder:
ls -l > list.sql
Edit and set @ before each file name
vi list.sql
1,$s/^/@/

sqlpus ich/foo@mydb
@list.sql

Convert latin1 to UTF-8 in MySQL
$ mysqldump -h localhost –user=myName -p –default-character-set=latin1 -c \
–insert-ignore –skip-set-charset dbname > dump.sql
$ iconv -f ISO-8859-1 -t UTF-8 dump.sql > dump_utf8.sql

Find out which charset is my file

$ iconv -f 8859-1 -t utf-8 FILE1> FILE2
$ iconv -f utf-8 -t 8859-1 FILE2 > FILE3
$ diff FILE1 FILE3

apt-get –purge remove NameOfPackage
apt-get install –reinstall NameOfPackage
z.B:
apt-get –purge –reinstall install apache2.2-common apache2
apt-get install –reinstall libapache2-mod-php5 php5-cli php5-common php5-cgi

dpkg-reconfigure xserver-xorg
update-alternative -config x-session-manager

lpstat -t
cancel
lpadmin -p lj -E

PSI=’\u@\h:\n$’

wget -c –user=user –password=passwd http://hostname…

find -name ‘*.[ch]‘ | xargs grep -E ‘expr’
find -type f -print0 | xargs -r0 grep -F ‘example’

find . -exec grep “use GD” ‘{}’ /dev/null \; -print
find . -name “*.pl” -type f -exec grep “use GD” ‘{}’ /dev/null \; -print

Only get diffs. Do multiple times for troublesome downloads:
rsync -P rsync://rsync.server.com/path/to/file file

سخت افزار هاى لازم

	واما سخت افزار هاى كه براى ساختن ISP در سطر اول قرار دارند. معمولا بيشتر استفاده كننده ها براى ورود به اينترنت  از modem  استفاده ميكنند. براى جواب دادن تلفنها ISP قاعدتا به يك RAS  -   remote access server احتياج دارد. RAS يك قوطى است كه يك سرش به خط تلفن T1/E1 or PRI كه از شركت مخابرات آمده  وصل ميشود و سمت ديگر آن به Ehternet switch كار RAS جواب دادن تلفنها و به عبارتى برداشتن گوشى تلفن است . سخت افزار بعدى يك router است كه براى ISP هاى كوچك معمولا يك cisco 2501 كافى است. كار اصلى router وصل شبكه  ISP به  upstream provider است كه هيچ چيزى نيست غير از يك ISP ديگر upstream provider در حقيقت يك subnet of IP ادرس معمولا ۲۵۶به ما ميدهد. بعدا احتياج به يك CSU/DSU يا NTU داريم كه router را به خط T1/E1 ياDSL  وصل كند.
طرزكار ورود به اينترنت
بعد از اينكه كامپيوتر استفاده كننده از طريق  modem  شماره تلفن  ISP را ميگيرد مخابرات تلفن را از روى خط (T1 line) ميگيرد و به RAS  ما وصل ميكند. يك خط T1 ميتونه ۲۸ تلفن مختلف را همزمان  دريافت كند. Terminal-Server همان  (RAS ) جواب تلفن را ميدهد و  يك ارتباط PPP برقرار ميشود و بدين ترتيب كه اول از سرعت بالا۵۶۰۰۰ كيلو بيت  اگر نشد با سرعت كمتر ارتبات را نگه ميداره و از طريق PPP   بعد از اينكه نام و پاسپورت را دريافت كرد از Radius-Server صحت انرا سوال ميكند و در صورت درست بودن  اتوماتيك يك آدرس IP به فرستنده ميدهد و بدين وسيله كامپيو تر به شبكه سرتاسرى اينترنت وصل ميشود.
بخاطر مخارج زياد و مشكل بودن راه اندازى (configuration) و گران بودن سخت افزار  كمتر ISP حاضر است خط مستقيم   (Standleitung) با يك  Backbone-Provider داشته باشد.
