Google Maps API in Twitter Bootstrap Tabs

nospam@example.com (Peter Rehm) — Tue, 22 Jan 2013 18:40:21 +0100

It is a common request to use the Google Maps API in some a tab.
I came across the issue again today using Twitter Bootstrap. If you
embed the MapCanvas not on the first tab you will notice that the
Map will not be fully loaded...

The issue can be solved with calling

CODE:

google.maps.event.trigger(map, 'resize');

once the tab on which the map is included is activated.

If you have the following tabs (Example using an tabbed form)

CODE:

<ul class="nav nav-tabs">
    <li class="active"><a href="#tab-first" data-toggle="tab"><i class="icon-tasks"></i> Todo</a></li>
    <li><a href="#tab-second" data-toggle="tab"><i class="icofont-leaf"></i> My fancy Map</a></li>
</ul>

<form action="#" method="post" class="form-horizontal tab-content well">
    <fieldset id="tab-first" class="tab-pane active">
        <h2>Form elements to be added here...</h2>
    </fieldset>
    <fieldset id="tab-second" class="tab-pane">
        <div id="mapCanvas" class="span6 pull-right"></div>
        <h2>Fancy Map</h2>
    </fieldset>
</form>

you can handle the resize with the following JavaScript Snippet.

CODE:

I hope this helps you!

git; insufficient permission

nospam@example.com (Peter Rehm) — Tue, 08 Jan 2013 10:32:56 +0100

If you get the following error

CODE:

error: insufficient permission for adding an object to repository database .git/objects
fatal: failed to write object
fatal: unpack-objects failed

you have messed up something with the permissions. In this case you have to ensure,
that the permissions of the .git file get fixed.

CODE:

chown -R user.group .git

Symfony2 Ordered Fixtures

nospam@example.com (Peter Rehm) — Wed, 17 Oct 2012 19:33:40 +0200

If you want to set the order in which the Fixtures are boing loaded there are
two steps:

- Use the AbstractFixture Interface

CODE:

class LoadCompanyData extends AbstractFixture implements OrderedFixtureInterface

- Add getOrder Methode

CODE:

public function getOrder()
{
return 1;
}

Than it will work.

Symfony2 Permissions on Mac

nospam@example.com (Peter Rehm) — Wed, 17 Oct 2012 19:31:39 +0200

To configure the permissions on mac use the following commands:



sudo rm -rf app/cache/

sudo rm -rf app/logs/

sudo chmod +a "_www allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs

sudo chmod +a "yourusername allow delete,write,append,file_inherit,directory_inherit" app/cache app/logs

Compare Content of 2 Folders

nospam@example.com (Peter Rehm) — Sat, 25 Aug 2012 12:29:32 +0200

If you need to compare 2 folders on a windows machine to figure out
whether the content matches to check e.g. if you have really copied
all files you can do this on the command line.

CODE:

- open cmd
- cd folder1
- dir /S /b > content_folder1.txt
- cd folder 2
- dir /S /b > content_folder1.txt
- fc content_folder1.txt content_folder1.txt

Hint: You can also pipe the output of fc by adding "> diff.txt".

Compiling error regarding xcode select

nospam@example.com (Peter Rehm) — Sat, 18 Aug 2012 17:03:38 +0200

If you get this error

CODE:

xcode-select: Error: No Xcode is selected. Use xcode-select -switch <path-to-xcode>, or see the xcode-select manpage (man xcode-select) for further information.

Make sure that you have the Apple Command Line Tools from https://developer.apple.com/downloads/index.action?=command%20line%20tools installed. This should be necessary unless you want to develop OSX or iOS applications.

Then just execute this on the command line to set the default entry.

CODE:

sudo xcode-select -switch /usr/bin

There you go...

.DS_Store aus GIT Repository entfernen

nospam@example.com (Peter Rehm) — Sat, 04 Aug 2012 13:13:05 +0200

CODE:

find . -name .DS_Store -print0 | xargs -0 git rm --ignore-unmatch --cached

modify .git/info/exclude

CODE:

# git ls-files --others --exclude-from=.git/info/exclude
# Lines that start with '#' are comments.
# For a project mostly in C, the following would be a good set of

Installation PEAR/PECL/autoconf/intl/icu auf Mac OSX Mountain Lion

nospam@example.com (Peter Rehm) — Wed, 01 Aug 2012 21:11:24 +0200

Installation PEAR/PECL/autoconf/intl/icu auf Mac OSX Mountain Lion

- Install PECL & PEAR

CODE:

cd /usr/lib/php
sudo php install-pear-nozlib.phar

- Add to php.ini

CODE:

include_path = ".:/usr/lib/php/pear"
extension_dir = "/usr/lib/php/extensions/no-debug-non-zts-20090626"

- Update pear channels

CODE:

sudo pear channel-update pear.php.net
sudo pecl channel-update pecl.php.net
sudo pear upgrade-all

- Install ICU from http://site.icu-project.org/download/48#ICU4C-Download

CODE:

tar -xzvf icu4c-4_8_1_1-src.tgz
cd icu/source/
./runConfigureICU MacOSX
make
sudo make install

If you get something linke this...

configure: error: in `/Users/peterrehm/Downloads/icu/source':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details
./runConfigureICU: ./configure failed

you have to install the apple command line tools which you will find
under the following URL for the appropriate OS version like Mountain Lion.

CODE:

https://developer.apple.com/devcenter/mac/index.action

then you should be able to install it..

CODE:

sudo pecl install intl

If you have autoconfi missing go for that:

CODE:

curl -O http://ftp.gnu.org/gnu/autoconf/autoconf-latest.tar.gz
tar -xzvf autoconf-latest.tar.gz
cd autoconf-2.69/

Now you should add "extension=intl.so" to php.ini and restart apache. Here you go.

MAC OSX; Locate Database aktualisieren

nospam@example.com (Peter Rehm) — Wed, 01 Aug 2012 07:56:24 +0200

Mit dem folgenden Befehl wird die Erzeugung des locate Indexes angestoßen:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.locate.plist

Anzeige der git branch in der Console (OSX/bash)

nospam@example.com (Peter Rehm) — Sun, 29 Jul 2012 19:26:01 +0200

.bash_profile anlegen mit dem folgenden Inhalt

PATH=$PATH:/usr/local/git/bin:.
source /usr/local/git/contrib/completion/git-completion.bash
PS1='[\u@\h \w$(__git_ps1 " (%s)")]\$ '

Danach sieht der shell prompt wie folgt aus:

[peterrehm@tokyo-3 /www/scalc (master)]$

Dadurch wird nebenbei auch die completion hinzugefügt, zum Beispiel bei
der Auswahl der Branches mittels git branch ...

Script für externes Subversion Backup

nospam@example.com (Peter Rehm) — Sat, 30 Oct 2010 23:18:34 +0200

Mit diesem Script werden verschiedene Daten gepackt und in mit einem Dateinamen der
das Datum enthält "Datum_Serverbackup.tgz" versehen.

CODE:

#!/bin/bash
filename=`date '+%m%d%y'`
rm -rf /opt/tmpdir/backup/*

mkdir /opt/tmpdir/backup/svn/
mkdir /opt/tmpdir/backup/config/

svnadmin dump /home/svn/cms/ > /opt/tmpdir/backup/svn/cms_svn.dump
svnadmin dump /home/svn/templates/ > /opt/tmpdir/backup/svn/templates_svn.dump

tar -cvf /opt/tmpdir/backup/config/apache.tar /etc/apache2/
tar -cvf /opt/tmpdir/backup/config/opt_scripts.tar /opt/scripts/

tar -czvf /opt/tmpdir/backup/${filename}_serverbackup.tgz /opt/tmpdir/backup/*

PEAR unter OSX Leopard installieren

nospam@example.com (Peter Rehm) — Wed, 02 Jan 2008 11:16:31 +0100

Im folgenden wird in aller kürze beschrieben, wie man PEAR unter
OSX 10.5 Leopard installiert. Dies sollte unter den vorherigen OSX
Versionen sicher ähnlich funktionieren.

Auf meinem lokalen System habe ich PHP5 von entropy.ch am laufen, da
ich unbedingt die GD-Lib benötige. Dies hat nur Einfluss auf die Ablage
der php.ini. Dies muss eben von den auf dem jeweilig auf dem System vorhandenen
Gegebenheit abhängig gemacht werden.

Wir werden in /usr/local/ installieren, und dem System gestatten die TEMP-Files
in /usr/local/temp abzulegen.

CODE:

sudo mkdir /usr/local/temp
sudo chmod -R 777 /usr/local/temp
sudo mkdir /usr/local/share/pear
sudo chmod -R 777 /usr/local/share/pear

Im nächsten Schritt wird go-pear ausgeführt.

CODE:

curl http://pear.php.net/go-pear | php

Hier muss bei den Pfaden der 1. auf /usr/local geändert werden.
Alle anderen Einstellungen können in der Regel beibehalten werden.

Während der Installation kommt dann die Warnung, dass der PEAR Pfad
noch nicht in der php.ini vorhanden ist, und es deswegen zu Problemen
mit der Verwendung von den PEAR Scripts kommen kann.

Hier kommen wir an den Punkt wo es wichtig ist, zu wissen, wo die
Konfigurationsdatei des Webservers liegen muss. Dies kann man einfach
über ein kurzes Script herausfinden:

CODE:

<? phpinfo(); ?>

Im Browser die Datei ansehen und nach folgender Zeile suchen.

CODE:

Configuration File (php.ini) Path /usr/local/php5/lib

Hier muss die php.ini für den Webserver liegen, die php.ini für
das Command-Line-Interface (CLI) unabhängig davon in /etc/

Standardgemäß ist eine php.ini.default in /etc/. Diese kopieren
und modifizieren wir zunächst.

CODE:

sudo cp /etc/php.ini.default /etc/php.ini
sudo nano /etc/php.ini

Nun nach dem Eintrag include_path suchen und diesen um "/usr/local/share/pear"
ergänzen. Bei mir sah dies nach der Anpassung so aus.

CODE:

include_path=".:/usr/local/share/pear"

Ist eine php.ini in dem Config-Path des Webservers vorhanden bearbeiten
wir diese, ansonsten kopieren wir die Datei /etc/php.ini an die gewünschte
Stelle

CODE:

sudo cp /etc/php.ini /usr/local/php5/lib/php.ini

Abschließend muss noch der Webserver neu gestartet werden, dann ist PEAR
einsatzfähig.

CODE:

sudo apachectl restart

Anmerkung: Kann PEAR von der Konsole nicht mit dem Befehl pear aufgerufen werden,
ist /usr/local/bin nicht korrekt in den SHELL-Pfaden eingetragen, und sollte nachgetragen
werden. Tipp: echo $PATH zum überprüfen in der SHELL eingeben.
