Servlet Using Google Vision API Sample

Servlet Using Google Vision API

A simple servlet with POST getting an image URL and performs a SAFE SEARCH check using Google Vision API.

Note that it doesn't contain authorization. You can do it locally on your machine or run it live at App Engine using it's service account (it does that automatic so you just deploy it).

Authorize Jenkins to Google App Engine

I usually want everything in the cloud including my Jenkins server. I've been using Bitnami for this but each time I've the same problem of authorize since in the middle of the build Google asks Jenkins to follow a URL and authorize and then paste a key.

Bitnami

Bitnami is an excellent cloud service where you can run services in the cloud. I choose an installation in Europe using Google Compute API and with a Jenkins Image.

When creating your Virtual machine with Jenkins you start an installation wizard where you can select the most common plugins like Maven.

Preparation

It's necessary to know where Maven is installed. This is a simple way to do it without using a console.

Make sure you have installed "Maven Integration Plugin"
Create a Freestyle project and add a "Execute shell" buildstep with the following command:
find / -name "mvn"
Check the console for Maven installation folder

Maven Google App Engine Project

Let's create the Maven Google App Engine Project and authorize!

Create a "Freestyle project"
Enter project details like Source code and build triggers. At "Build step" add "Execute bash" as "Build step". Run maven with:
/opt/bitnami/apps/jenkins/jenkins_home/tools/hudson.tasks.Maven_MavenInstallation/Maven/bin/mvn appengine:update
This will fail since the App Engine plugin will stop for a authorization. It prints an URL which Jenkins cannot open. Follow the link in your browser and sign in using your Google account. Copy the key you receive.
Update your project and change the command to:
echo "key-you-got-from-your-browser" | /opt/bitnami/apps/jenkins/jenkins_home/tools/hudson.tasks.Maven_MavenInstallation/Maven/bin/mvn appengine:update
Run the project and you should be authorized!

What happens is that your key is entered when Maven stops for input.

Compiling JavaScript on Serverside With Scala and ScalaJS

Since my experience with the JavaScript world and exploration of ScalaJS I felt compelled to move from Node and Grunt and try to fully utilize Scala for both front and back.

I reached a goal with Scala Stack, a concept of creating all web content on serverside using only Scala code. The concept is extended to keep everything in code including configuration to be fully testable.

Future of Internet

If we try to look into the future of internet, I think we see two strong forces: Market and AI.

How will they alter the internet we use today?

Market want to extract most of its users and want to create webpages which are fully personalized in an effort to guide the users to their goals. Sites are personlizing the pages by user settings but why shouldn't all content including color and shape be adopted to the user in a effort to please the user as much as possible?
AI and ML is on the uprising and if the server is thinking for itself it could create whatever as a response.

Obvious Advantages

My main purpose was to skip the JavaScript world but it moved on to something much larger. If all code is shared there are quite a few advantages

Single, isomorphic source which ease work and can share logic
Share data by keeping it in code. For instance languages could be defined with a Enum type
Fully testable code
No JavaScript package manager like NPM or WebPack
No pre processor like Gulp or Grunt

Risks

There are some traps though

Security, some code should not be shared
Long term effects, demands a experienced architect
Shared code needs to be ScalaJS compatible and cannot use backend dependencies since it's compiled and used on frontend

Scala Stack

I've made three implementations using Google Flexible Environment. Implemented in native JavaScript, jQuery and AngularJS.

Goal is to keep everything in code and to avoid configuration, annotations and settings in Strings.

By only using Scala on serverside, it produce HTML, CSS and JavaScript which is all components for a webpage.

Servlet Compiler

Scala Stack is using a Servlet compiler with different logging:

Moi

I discovered C and JavaScript in school 98-99 and have coded since.

As an individual the first problem is to be creative within the little time that is left of work and social life. Keeping goals through discipline and understand how to be efficient was fundamental. 2012 I discovered Google App Engine and within a single JSP-file kept HTML, CSS, JavaScript and Java with a database connection, I was hooked! This was all I needed to create a site. The PaaS handled publication, dashboard, configuration of services, hosting, logging and have a big library of API for the basic operation, which meant I could spend time on coding.

Mixing code with a subject are my main interests and when creating my first sites I understood that it's impossible to create content driven sites by myself. The solution was to give the users tools to modify the site as they witched and, as a community, create the site they wanted in a democratic way.

2 recorded wins using Art of Camping (Diamond IV)

2 Recorded Wins Using Art of Camping

You can read about the tactics here.

1 Win

Watch it here

0:00-05:00 Going for the farm north east (I2). There is usually no players there and it's easy to loot.
The first circle isn't too far away. I calculate it's about 3 squares away and takes 6 minutes. The first gas is spreading for 5 minutes so I need to go 1 min before it starts.
I need to cross plains which is dangerous since there is often cars "sharking" and looking for a kill. But I was lucky and could advance north and far away from the center.
15:00-20:00 I stay at Dragon Lake (E3) and hear some gun shoots.
20:00-25:00 The final is at Harris Ridge (D3) and I advance from north, going around the mountain on the north side, again far from the center.
30:00 I don't spot the last player and advance to top corner of gas. But finally I spot a car, make cover with smoke and throw grenades. My opponent is hiding behind a hill and I charge with shotgun winning!

2 Win

Watch it here

03:00-05:00 Looting at far south west at the farm (B9). This is a safe place but far away.
06:00-14:00 The first circle is far away, about 4 squares, and luckily I find a car, otherwise I would need to run for about 8 minutes (2 minutes per square)! I drive on the south side of Runamok River to avoid players and then north to the church at Humberdink Reserve (J6).
14:00-26:00 I ditch the car to advance quietly.
27:00-31:00 There is some fighting and I advance to the far away north part of the final circles.
31:00-33:00 The last player have a car and I hide until the car drives by me to shoot at it in the passing. I use smoke grenade to cover me when I change position. finally I charge the car is burning and the player is moving out. I throw smoke grenade to advance the get shoot at. Finally the other player is hiding behind a rock and I win by throwing hand grenades!
