Not being able to easily run my browser test is a pain so I tried to give a shot to the new test_runner package from Nicolas Garnier. However having content_shell setup is not a done deal so thanks to http://japhr.blogspot.fr/2014/09/dart-content-shell-on-debian.html  I was able to set it up conveniently Download content shell and add it to the path cd $DART_TOP/chromium ./download_contentshell.sh unzip content_shell-linux-x64-release.zip CONTENT_SHELL_PATH=$(ls -d drt-*) PATH=$PATH:$CONTENT_SHELL_PATH install the missing package (fonts) sudo apt-get install wdiff ttf-indic-fonts ttf-mscorefonts-installer ttf-dejavu-core ttf-kochi-gothic ttf-kochi-mincho Make sure you have everything in your path (pub, dart2js, ~/.pub-cache/bin) and run_tests can be ran on any project. I had to rename some files to have the expected conventions.

As I do maintain multiple wordpress site that share common source code, the easiest for me was to install a wordpress multisite locally. Assuming you managed to install lamp and wordpress, these are the additional step needed before enabling multisite Activate the apache Mod_Rewrite module: $ sudo a2enmod rewrite Allow .htaccess changes in the virtual file. Open your default virtual host file (assumed). $ sudo gedit /etc/apache2/sites-enabled/000-default In the Directory section, change AllowOverride to All: <Directory /var/www/>                 Options Indexes FollowSymLinks MultiViews                 AllowOverride All                 Order allow,deny                 allow from all </Directory>

Summary of the command line to use $ sudo apt-get install npm nodejs $ sudo npm install bower -g $ ln -s /usr/bin/nodejs /usr/bin/node Explanation You need both nodejs and npm $ sudo apt-get install npm nodejs Then you can install bower $ sudo npm install bower -g Quick check $ bower --version You might get /usr/bin/env: node: No such file or directory which you solve using $ ln -s /usr/bin/nodejs /usr/bin/node Quick check again $ bower --version 1.3.12 Yeah!

After trying to run google cloud hello world for dart  on Ubuntu and after installing gcloud sdk and using the following command $ gcloud preview app run app.yaml I was getting: ERROR : (gcloud) Invalid choice: 'preview'. Solution is to run: $ gcloud components update preview Then I was getting ERROR : (gcloud.preview) Invalid choice: 'app'. Solution is to run: $ gcloud components update app As it turned out, I could have simply done this in one command $ gcloud components update preview app

I wanted to speed up my Android Emulator on my i5 desktop PC to try Android 5.0 Lollipop I created a x86 AVD running Android 5.0 (I could not manage to use a x86_64 image as it was either slow or crashing) KVM Intel processor seems to be required for now First check if KVM can be used $ sudo apt-get install cpu-checker $ kvm-ok INFO: /dev/kvm exists KVM acceleration can be used otherwise check your BIOS to enable KVM I then simply append  -qemu -enable-kvm to the command line (it has to be the last option) I use to start my emulator Open GL Make sure use Host GPU is checked in the your AVD or append  -gpu on to your emulator command line To solve the following issue: Could not load OpenGLES emulation library: lib64OpenglRender.so: cannot open shared object file: No such file or directory Here the solution is to add the tools/lib directory to LD_LIBRARY_PATH My final command line, assuming ANDROID_SDK point to you android sdk installation (in my case:...

I wanted to try oracle jdk vs openjdk performance for the DartEditor http://www.oracle.com/technetwork/java/javase/downloads/index.html I chose jdk-7u71-linux-x64.tar.gz that I extracted to /opt/apps/jdk1.7.0_71 Then comes the configuration: # One time setup # local var $ LOCAL_JAVA_TOP=/opt/apps/jdk1.7.0_71 # setup sudo update-alternatives --install /usr/bin/java java $LOCAL_JAVA_TOP/bin/java 110 sudo update-alternatives --install /usr/bin/javac javac $LOCAL_JAVA_TOP/bin/javac 110 Then to change configuration: # To change configuration between openjdk / oracle sudo update-alternatives --config java sudo update-alternatives --config javac At first, Oracle looks slightly slower in a simple test where I started exited the editor with a complex project. However the overall experience looks slightly faster...to be completed after some days of usage...

In finishing my "migration to a new machine" process, since I kept my old ssd drive. However the trash on this drive was not working and deleting a file was always giving: are you sure you want to permanently delete “xxx”? I had 2 issues: my user could not write on the root of the drive my user could not write in the existing trash The simplest was to own the drive $ sudo chown xxx:xxx /media/xxxx As I  have other user accessing the drive, I also has to change the permission $ sudo chmod 0775 /media/xxxx
