Install "File node " in Node-red palette - file

I'd like to use "File Node" in Node-Red. I expected to find it in the storage section in the palette but it isn't in my palette, I try to install using the option Manage Palette in my Node-Red application but I am not able to find/identify the node in the repository .
Could someone telling me how to find the node description to install it in my palette?. Why a don't have it as default?.

The File nodes are disabled by default in the Bluemix environment to discourage writing files to the volatile storage that will be lost whenever the app is restarted.
You can re-enable it by editing your applications bluemix-settings.js file and remove the file.js entry in the nodeExcludes option.

you can use "node-red-contrib-browser-utils" with the option Manage Palette in Node-Red

team work with codename one

i am a student and i am a member of a group of five...
We have to work in the same project using git and we are using Scrum method in our work, so , we need some guide and best practice and answers before starting...we will be so happy with your informations.
can we use différent IDE (intellij and Netbeans)... if yes, the .gitinore file will contains every IDE 's specefic .gitignore file?
You can use this to get started: https://www.codenameone.com/blog/tip-using-git-for-codename-one-projects.html
e.g. sample gitignore from https://github.com/codenameone/MaterialScreensUIKit
*.jar
nbproject/private/
build/
nbbuild/
dist/
lib/CodenameOne_SRC.zip
psds/.DS_Store
.DS_Store
In your theme editor make sure the File -> XML Team Mode is checked for everyone so you can work on XML and individual files rather than the whole thing.
Alternatively you can avoid the designer tool altogether and use CSS.

Change the default location of Pycharm Project

I am using PyCharm 3.4.1 on Ubuntu 14.04. For new project it suggests ~/PyCharmProjects for storing project folders. Is it possible to change the location and name of this proposed folder?
(I couldn't find any reference to changing it in the interface, on the JetBrains site, or in the settings files. Either it isn't possible or (I hope) I missed something.)
Note, it is not a duplicate of Can I change the location/name of PyCharmProjects? - I am aware that it is possible to change proposed path for every created project - but I want defaults that I like.
I know this is an old question, but is is certainly possible as of now
Settings | Appearance & Behaviour | System Settings | Default directory
See JetBrains support page

In fact, this is possible. In the IDE settings folder (https://www.jetbrains.com/help/pycharm/project-and-ide-settings.html), under config/options/recentProjectDirectories.xml, you can add an option lastProjectLocation. It wil honor this setting when creating new projects. My recentProjectDirectories.xml looks like this:
<application>
<component name="RecentDirectoryProjectsManager">
<option name="lastProjectLocation" value="$USER_HOME$/my_projects" />
</component>
</application>
In fact, for most options that you want to customize, you could do a diff of the config/options folder before and after you make the change: this way you can find out a lot about how PyCharm (or any IntelliJ tool) configures its editor.
I haven't found an explicit option for doing this in PyCharm, but the following steps have worked as an alternative:
Move your PycharmProjects folder to the desired location.
When you create a new project, press the "..." button to the right of the path (This is on the pop up window that asks for location and interpreter).
Navigate to the new location of PycharmProjects and select that directory.
Add the name of the new project to the directory location (ie. /home/alex/Documents/PycharmProjects/new_project_name)
Now, whenever you create a new project, the location will default to the last chosen path.
This wouldn't be a good solution for someone who is creating projects in many different directories, rather than just PycharmProjects. All my projects are within PycharmProjects and this works just fine.
PyCharm (since at least version 2017) remembers the parent directory of the last place where you created a project. So create a junk project in the directory that you want to be your default projects directory, then close that project, and delete it from disk. The next time you create a project, pycharm will automatically put you in that directory.
It's not a provided option. See this old thread (2003) on devnet.jetbrains.com where this is being discussed.
Subsequent requests to specify a default directory for projects has gone unanswered:
https://devnet.jetbrains.com/thread/157005;jsessionid=5A2C7A1F90969DEAD3908924FFF1AF3A?tstart=1

https://devnet.jetbrains.com/thread/67231;jsessionid=5255DB0AAB942F0DCDF1B86AFFE54976
Just an update to #Psionman's answer. At least in the professional version (2019.3.5), t appears to have shifted just a bit. The field is now available at
File | Settings | Appearance & Behavior | System Settings > Project Opening > Default Directory
The latest version 2021.3 has the following option:
File | Settings | Appearance & Behavior | System Settings > Project (Dialogue) > Default project directory
Just like virtualenvwrapper, PyCharm apparently obeys $PROJECT_HOME
export PROJECT_HOME=$HOME/Devel
pycharm
or
PROJECT_HOME=$HOME/Devel pycharm
I would have to agree, because I could not find an option in the program. However, based on the answers, found a folder labeled (in my case)
\Users\.PyCharmCE2018.1\config\options
In this folder there are XMLs, one named option with a tag "file.chooser.recent.files". I worked with this, which I found to work for me.
Maybe this also serves:
File -> Settings -> Project (name) -> Project Structure -> Add Content Root
Add folders and then create files and/or navigate between them easily.

How do I rename the context root of Application Center in Worklight 6.2?

I want to rename appcenterconsole to devappcenterconsole, and applicationcenter to devapplicationcenter. I am running Worklight 6.2 on Tomcat. I wonder if this is as simple as rename the war file, deploy it and update the server.xml?
See the Context container in the Tomcat documentation : http://tomcat.apache.org/tomcat-7.0-doc/config/context.html
Especially the path attribute description.
You can for example modify the path attributes with : /devappcenterconsole and /devapplicationcenter.
Be aware also that if you modify the default context root of applicationcenter you must configure the endpoint property as documented in http://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.installconfig.doc/appcenter/r_ac_endpoint_tomcat.html?lang=en

Missing Ubuntu.Components QML Module

I installed QTCreator and Ubuntu SDK as shown here.
When trying to run the code sample provided here, QTCreator tells me it can't find the Ubuntu.Components QML Module.
Notes:
The build-logs says:
file:///home/giladnaaman/Programming/Projects/CurrencyConverter/CurrencyConverter.qml:2 module "Ubuntu.Components" is not installed
But the directory /opt/qt5/imports/Ubuntu/Components
exists (and is full of files).
After adding importPaths: [ "/opt/qt5/imports" ] to the qmlproject file:
QML module does not contain information about components contained in plugins.
QMetaType::registerType: Binary compatibility break -- Type flags for 'QPaintBufferCacheEntry'[1024] don't match. Previously registered TypeFlags(0x103), now registering TypeFlags(0x3).
Do not add the importPaths property to the qmlproject.
Did you setup the QML Scene as your QML viewer?
In Qt Creator, go to Tools > Options…
Choose the External Tools tab, then in the pane select the Preview (qmlviewer) entry
On the Executable: field on the right, replace the contents with /opt/qt5/bin/qmlscene.
Optionally change the command name by double-clicking on the Preview (qmlviewer) entry from above. You can call it Preview (qmlscene).
Click on OK to save the changes.
you’ll be able to view your app through the Tools > External > Qt Quick > Preview (qmlscene)
The Ubuntu SDK is still using the older version of Qt Creator from QT4 it will not be able to locate the Ubuntu Components, and say the components are not found. But the QML Scene used for running the QML GUI will load it and run it without any problems.

problems configuring qooxdoo Inspector component

I am trying to configure the Inspector component as per instructions here: http://manual.qooxdoo.org/current/pages/application/inspector_selenium.html#pages-application-inspector-selenium-using-the-qooxdoo-inspector-to-write-selenium-tests
I am having problems following the configuration instructions, where it says to configure the Selenium window with the selenium-core zip file. I cannot find this file at the provided address: http://seleniumhq.org/download/
Any suggestions as to what I should use instead of that zip file?
Thanks
You can just press the "Use default URI" button in the Inspector's Selenium Options window and it will load the scripts from the Selenium SVN repository on Google Code. If that doesn't work for you it gets a bit complicated since the Inspector requires a deprecated version of Selenium:
Download Selenium RC from here and unpack it:
https://code.google.com/p/selenium/downloads/detail?name=selenium-remote-control-1.0.2.zip
Then extract
selenium-remote-control-1.0.2/selenium-server-1.0.2/selenium-server-standalone-1.0.2.jar to a directory named e.g. "selenium-server" and enter the path to that directory in the Inspector's Selenium Options window.
