Exporting an existing local Git repository to Github

To do so, I followed the Github documentation:

    https://help.github.com/articles/importing-a-git-repository-using-the-command-line/

. It worked. In this blog, I am trying to understand what exactly I have done.

On a remote computer (IP 192.168.1.5), I did some work that I wanted eventually to go to Github, so that I would be able to access my work from anywhere. I renamed the root directory of the project containing this work to minetats-webapp.git, so that the name would correspond to the empty Github repository I created following the doc mentioned above. On that computer, I created a Git repository with cd minetats-webapp.git && git init.

On the local computer, I cloned that repository with

git clone --bare ssh://192.168.1.5:/home/alec/project/minetats-webapp.git

. Then I did

cd minetats-webapp.git/

git push --mirror https://github.com/amissine/minetats-webapp.git

, and it worked. Before I ran cd .. && rm -rf minetats-webapp.git to clean up,
I took a look at what was inside the directory I was about to remove. The directory contained what a typical .git directory inside a Git repository would contain. So much for understanding. When I cloned my work from Github to test it locally,

git clone https://github.com/amissine/minetats-webapp.git

, it was successfully cloned into minetats-webapp.

A Node.js Rookie Diary

To run your code in a browser, you write it in javascript these days. With node.js, the server-side code can be written in jabascript too. Both sides need to be configurable, need to support dependency injection. Finally, the server side needs to be an HTTP server. The package.json file below reflects my picks on these dependencies:

{

  "name": "webapp.js",

  "version": "1.0.0",

  "description": "A web application with common dependencies",

  "main": "./lib",

  "scripts": {

    "test": "grunt nodeunit"

  },

  "dependencies": {

    "konfy": "0.1.3",

    "dijon": "0.6.1",

    "flatiron": "0.4.3",

    "director": "1.2.8",

    "http-server": "0.7.5"

  },

  "author": "Alec Missine",

  "license": "MIT"

}

 I created it with npm init, then manually edited the dependencies part. Having installed these dependencies in your $WEBAPP_HOME with npm install, you now can

cd $WEB_HOME

node $WEBAPP_HOME/node_modules/http-server/bin/http-server

The static content of your $WEB_HOME will be served on port 8080. If you do not want to cd $WEB_HOME, you can node $HTTP_SERVER_HOME/bin/http-server $WEB_HOME.

To familiarize myself with http-server, I ran

node-inspector &

node --debug node_modules/http-server/node_modules/union/examples/simple/simple.js

in one terminal window, and

curl -d "data to post" http://localhost:9090/foo

in another, while directing my Chrome browser to http://127.0.0.1:8080/debug?port=5858 .  In the browser, I was able to debug the simple.js code.

Using Pax Construct

history:
git clone https://github.com/ops4j/org.ops4j.pax.construct.git
cd org.ops4j.pax.construct
mvn clean install
mvn site

Spring DM Example:

#!/bin/sh

#--------------------------------
# let's start with a new project
#--------------------------------

pax-create-project -g examples -a spring

cd spring

#-----------------------------------------------------------------------------------
# first import the Spring Dynamic-Modules Extender bundle - we use importTransitive
# to also import any bundles it depends on and widenScope to do an exhaustive check
# of all dependencies (normally only "provided" scope dependencies are checked)
#-----------------------------------------------------------------------------------

pax-add-repository -i com.springsource.repository.bundles.external -u http://repository.springsource.com/maven/bundles/external

pax-import-bundle -g org.springframework.osgi -a spring-osgi-extender -v 1.1.2 -- -DimportTransitive -DwidenScope

#------------------------------------------------------------
# create new OSGi service bundle with example code and tests
#------------------------------------------------------------

pax-create-bundle -p org.example.service -- -Djunit

#--------------------------------------------------------------------
# create new Spring Dynamic Modules bean with example code and tests
#--------------------------------------------------------------------

pax-create-bundle -p org.example.bean -- -Dspring -Djunit

#----------------------------
# finally, build and deploy!
#----------------------------

exec mvn clean install pax:provision "-Dframework=equinox"

Another scp peculiarity

If you want to scp the content of the current directory (its files and subdirs) to the target, you type:

     scp -r . $HOST:$TARGET

If you want to scp the current directory, along with its name, under the target, you type:

     scp -r ../$CURRENT $HOST:$TARGET

One might argue this is not an scp peculiarity, just my lack of knowledge. Accepted. But now I know!
