What is the difference between Pool and Lane in BPMN?
Its a common newbie question while doing BPMN modeling. The rule of thumb is “Swimming pools have multiple lanes”. So you can model a pool and then lanes inside it. This article provides in-depth knowledge on this concept.
I use brew utility for all my terminal based installation needs. However recently I had to deal with a corrupted brew install. To fix this I followed this link. The uninstallation and reinstallation worked fine and I now have a working brew instance.
The commands as mentioned in the above link are:
$ cd `brew –prefix`
$ rm -rf Cellar
$ brew prune
$ rm -rf Library .git .gitignore bin/brew README.md share/man/man1/brew
$ rm -rf ~/Library/Caches/Homebrew
$ ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”
I use RoboMongo extensively for all my Mongo development work / debugging. I however sorely needed a way to export JSON from it. A Stack Over Flow link came up in a Google search and I was able to export JSON for my use. Basically you need to execute this command which uses “printjsononeline” function provided by Mongo to give you one line JSON for each row in the collection:
db.getCollection('collection_name').find({}).forEach(function(x){printjsononeline(x)});
I needed to design a UI using JavaFX. I use SceneBuilder for building my UI. I found this invaluable link for using AnchorPanes concept to make it work inside TabPanels. It really cleared my concepts in a minute and I had a working tab based UI shortly.
I recently started exploring python and immediately ran into the following issue:
$ pip install requests
-bash: pip: command not found
A quick google search yielded this result. So basically on MacOS you have Python preinstalled along with easy_install command. So the following command installs pip:
$ sudo easy_install pip
Searching for pip
Reading https://pypi.python.org/simple/pip/
Best match: pip 9.0.1

A quick and handy solution indeed!
Adding docker containerization support in a working Spring Boot application is surprisingly easy.
Step 1: Add the docker maven plugin to your pom file.
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>1.3.4</version>
<configuration>
<repository>${project.artifactId}</repository>
</configuration>
</plugin>
</plugins>
</build>
Step 2: Build the application as well as the docker image
mvn clean package install dockerfile:build
Step 3: I have a local docker registry setup in my Lan so I prefer to push this image to my network registry manually (this can be automated as well however).
docker tag my-app:latest my_network_registry_host:5000/my-app
Step 4: Now we can bootup this docker image anywhere in the network.
docker run \ --detach \ --link <any database link> \ -e <Environment variable 1> \ -e <Environment variable 2> \ -p 8080:8080 \ --name my-app \ my_network_registry_host:5000/simply-hr
docker logs --follow simply-hr
Found a good article which enabled me to install python 2.7.3 inside a folder.

In order to setup a fully functional Redmine server via Docker I use the following consolidated command:
docker run \ --detach \ --name redmine \ --link mysql:mysql \ --publish 3000:3000 \ --env="REDMINE_DB_MYSQL: redmine" \ --env="REDMINE_DB_PASSWORD: redmine" \ --volume /Volumes/DATA/Abhinav/Docker/redmine/files:/usr/src/redmine/files \ redmine
This connects my mysql docker instance with sonar and it is able to create tables and start using MySQL properly for storing all it’s data.
I found a good piece of code which can be used to extract multiple email from a String. A modified version of the code is listed below:
public static String readContactEmailFromString(String resumeText) {
final String RE_MAIL = "([\\w\\-]([\\.\\w])+[\\w]+@([\\w\\-]+\\.)+[A-Za-z]{2,4})";
Pattern p = Pattern.compile(RE_MAIL);
Matcher m = p.matcher(resumeText);
StringBuilder sb = new StringBuilder();
while(m.find()) {
if (sb.toString().contains(m.group(1))) continue;
if (sb.toString().isEmpty()) {
sb.append(m.group(1));
} else {
sb.append("; " + m.group(1));
}
}
return sb.toString();
}
I am currently using Github and all project members have forked the main repository into private repository. Now the problem is that I need to review my colleagues code committed in his branch inside his forked repository. So to do this I found out a good article that showed me exactly how to do that. I used the following approach.
git remote add my-colleague https://github.xyz.com/my-colleague/project.git git fetch my-colleague git checkout -b my-colleague-branch --track my-colleague/branch
After I do this I can see all the work done by my colleague and I can switch back to my branch anytime.
