Ionic Framework est un framework open source permettant de développer des applications mobile "hybrides" iOS/Android/* en utilisant HTML5, CSS et JS, en particulier AngularJS. Ionic est également un framework CSS comparable à Bootstrap, et particulièrement optimisé pour les apps smatrphone/tablette.

Ionic génère une app qui est construite comme un site HTML5 / CSS / Js, embarqué dans une WebView, c'est à dire une fenêtre de navigateur web. Cette fenêtre est dans l'application, de manière transparente, de sorte que l'utilisateur n'a pas l'impression d'utiliser un navigateur ou une page web, mais bien une app mobile, téléchargée sur l'AppStore ou le PlayStore.

A l'inverse des apps "natives", écrite en Objective C ou en Java, les applications hybrides construites avec Ionic utilisent deux frameworks liés à des langages web :

Cordova, qui permet à Javascript côté client d'accéder aux API native du smartphone ou de la tablette (accéléromètre, giroscope, liste des contacts, etc.)

AngularJs, qui permet de construire des applications complexes basées sur HTML5, avec une organisation logicielle proche du modèle MVC.

La dernière version d'Ionic Framework inclue maintenant crosswalk-project.org, qui permet d'utiliser dans Ionic une Chrome Webview utilisant toujours la dernière version de Chrome, plutôt qu'une Webkit Webview, solution par défaut, mais dont la version est imprévisible puisqu'elle dépend de la version d'Android installée.

Dans une app iOS/Android, basée sur HTML/CSS/Js, construite avec Ionic, il est donc possible d'utiliser HTML5 : WebRTC, WebGL, Vibration API, WOFF web fonts, CSS feature queries, etc. en considérant que l'utilisateur bénéficiera des dernières fonctionnalités d'HTML5, telles qu'elles existent dans la dernière version à jour de Chrome. 

ditto

Copy files and folders

Ditto is specific to Apple, see man page

ditto Copy files and folders. Syntax ditto [options] Source_file Destination_file ditto [options] Source Destination_folder ditto -x [options] Source_Archive Destination_folder ditto -c [options] Source Destination_archive Where Source = a file, folder or archive. Options -c create an archive at the destination path. Use a file extension, .zip, .cpio or .cpgz (for Compressed CPIO archives) -v Print a line of output for each source folder copied. -k Instead of CPIO, assume PKZip archives. -V Print a line of output for every file, symbolic link, and device copied. -x the first source is an archive to extract. -X When copying one or more source folders, do not descend into folders that have a different device ID. -z -x implies -z. CPIO archives should be compressed. Uncompressed data flows through the decompressor unmodified.

Just updated your code in a pre-prod environment, hosted on the same  production env server. Purged and warmed caches, then started checking this website's new pre-production version. And... BOOM! website falls down weirdly, and your Apache2 error log outputs errors that just do not exists in your code :

PHP Classes methods declarations that suddenly become incompatible with the Interface they implement, 

Lines of code mentioned in error.log do not exist or are mismatched in your PHP code. No way to debug it.

etc.

This may be a simple cache key conflict situation in your APC usage.

By example in Symfony2, APC is proposed for autoloading, to improve performance. You configure it in the web/app.php file, and comments invite you to use a unique prefix in order to prevent such cache key conflicts with other applications also using APC.

But how to easily choose a different unique prefix between prod & preprod environments ? You may use by example a PATH-based short unique prefix, using crc32:

if (!extension_loaded('apc')) { $loader = new ApcClassLoader( sprintf('%u', hash("crc32b", __DIR__)), $loader ); $loader->register(TRUE);

}

To be 32bits/64bits switch proof, you need to ensure your prefix to be an unsigned int, using sprintf & %u.

And that's it!

A few more words on APC

APC is one of the most recommended Opcode cache system for PHP < 5.5. From 5.5 and after, Zend OPCache is included in PHP, so APC is no then more required, but it remains very helpful (say: mandatory) for any other previous 5.4.* versions of PHP.

This is my default personal configuration of it :

extension=apc.so apc.shm_size=128M apc.shm_segments=1 apc.max_file_size=5M apc.num_files_hint=10000 apc.slam_defense = 0 apc.write_lock=1

And this is how you may clear it manually for php-cli:

php -r "apc_clear_cache(); apc_clear_cache('user'); apc_clear_cache('opcode');"

Note that apc_clear_cache() should be called from within the process (or child process), say a php file served by Apache2.

Operations to perform while upgrading from 10.9:

- Apache is now 2.4: you need to change 2 lines in your vhost conf

You may encouter some "403 Forbidden" errors in Apache2-served websites, since Yosemite now introduces Apache2 "2.4" version, with some syntax changes. Some backward compatibility issues may appear, the most evident is a change in authorization rules syntax.

Just replace this, in your previous vhost conf file

(...) <Directory /path/to/website.com/web> (...) Order allow,deny Allow from all </Directory> (...)

by

(...) <Directory /path/to/website.com/web> (...) Require all granted </Directory> (...)

- jetBRAINS PHPStorm / Webstorm/ IntelliJ IDEA / PyCharm / RubyMine / etc. need a java upgrade

Java 7 is not available for OS X 10.10, but Java 8 is now available : you may need it for JetBrains products (, etc.), and such apps won't run on 10.10 until you update Java. a Java 8 ("Java SE Development Kit 8u25") is available on Oracle.com.

Once installed, you'll need to change the java version target in your jetBrains editor: Edit this file: /Applications/PhpStorm or even  .app/Contents/Info.plist

/Applications/PhpStorm.app/Contents/Info.plist

And change JVM version from 1.6.* to 1.6+ or even 1.8.* :

Tout ce que je raconte est authentique, je le jure sur la tête du mec qui a inventé w3schools.com

1 - Install php-cs-fixer globally - 3 available ways: manual / composer / homebrew) : cf. https://github.com/fabpot/PHP-CS-Fixer#usage

2 - Add php-cs-fixer as an external tool in PhpStorm : Open Settings (or "Preferences" on OS X) > External Tools & setup a new tool :

Fill with accurate paths & options:

Program: /my/homeDir/.composer/vendor/bin/php-cs-fixer

Parameters: (by example) --level=symfony --verbose --config=sf23 fix "$FileDir$/$FileName$"

Working directory: $ProjectFileDir$

To setup other php-cs-fixer options, check the one-page manual

BTW, have a look at [Settings/Preferences] > Code Style > PHP : PhpStorm can rearrange your code style with other nice style rules too.

Tested OK in PhpStorm 7 & 8 stable with php-cs-fixer stable.

It's easy, it's in your OS X & it runs faster than in a vm box 

Install PHP 5.5/5.4/5.3 for OS X 10.6/10.7/10.8/10.9 as binary package using the amazing php-liip (one-line command): curl -s http://php-osx.liip.ch/install.sh | bash -s 5.5

in /etc/apache2/http.conf, change the php5 path: LoadModule php5_module /usr/local/php5/libphp5.so as explained in the php-liip doc (but they're talking about uninstall, so do the opposite)

Use Brew to install MySql brew install mysql

launch mysql:  /usr/local/bin/mysql.server start

check root login without password is ok : mysql -u root -p and then exit

brew install phpmyadmin (Note: Someone may prefer Sequel Pro.app for OS X)

create a /etc/apache2/other/phpmyadmin.conf file containing this directives

restart apache2: sudo apachectl restart

Allow phpmyadmin to log you in without root password sudo cp /usr/local/share/phpmyadmin/config.sample.inc.php /usr/local/share/phpmyadmin/config.inc.php, then edit it and change this as true: $cfg['Servers'][$i]['AllowNoPassword'] = true Note that mysql root user has no password in the default brew-based mysql instance

Your new command-line binaries pathes are:

Your own Apache2 vhosts can now be created in /etc/apache2/other/*.conf or elsewhere (see /etc/apache2/httpd.conf). Just run sudo apachectl restart to take them in account.

Your MySQL server command is now in  /usr/local/bin/mysql.server but just mysql.server command should work as well Usage example: mysql.server restart PS: ZSH users, mind the native oh-my-zsh aliases & check your own ~/.oh-my-zsh/lib/correction.zsh conf.

Your PHP 5.5 instance is now installed in /usr/local/php5/bin. Usage example: php -v

Install Hhvm (45 minutes compilation) :

$ brew tap homebrew/dupes $ brew tap homebrew/versions $ brew tap mcuadros/homebrew-hhvm $ brew install hhvm

Set new aliases, including a "SlowTimer error" fix (see details):

$ alias composer="hhvm -v ResourceLimit.SocketDefaultTimeout=30 -v Http.SlowQueryThreshold=30000 /usr/local/bin/composer"
