Eclipse Kura MQTT Client Utility

This MQTT Client Application facilitates with all the MQTT related operations while using Eclipse Kura for IoT Application development.

The main motive of developing this application is to use Eclipse Kura's CRUD like feature provided by CloudLet. This requires all the payloads to be encoded and decoded using Google Protocol Buffer. If we use any of the widely available MQTT Client Tools, we can only be able to use MQTT Payloads of simple string type. This utility application provides you with all the opportunities to encode and decode your provided payload on the fly.

IThemeEngine not injected

In my last blog post, I have shown you how to you Jeeeyul’s Customized CSS templates in E4 application.

Many of you guys know about IThemeEngine which is used to change active theme in E4 Application. For further elaborative info, please have a look on the comprehensive tutorial by Lars Vogel.

http://www.vogella.com/tutorials/Eclipse4CSS/article.html

Here, you can see that IThemeEngine is considered to be an important dependency to be used for dynamic CSS Styling.

To be frank, it’s very strenuous to design a good css style for E4 Application. I, personally prefer using Jeeeyul’s themes which yields a professional look to the application. But if you want to use IThemeEngine to switch to themes dynamically, you won’t be able to get IThemeEngine injected to application model classes. This is pretty weird.

I have found a workaround to avail the same. Instead of injecting IThemeEngine, we can inject IThemeManager and then from that we can get IThemeEngine to switch themes dynamically.

Have a look at the sample code (in E4 Command Handler):

@Execute public void switchTheme(final IThemeManager manager) { final IThemeEngine engine = manager.getEngineForDisplay(Display .getCurrent()); engine.setTheme(AMIT_THEME, true);

}

Use Jeeeyul’s Themes in your E4 Application

Instead of striving too much to make your E4 application look beautiful, Jeeeyul has strived a lot to provide some cool E4 CSS scripts. If you search a bit in Google, you would find hell lot of results on how to install Jeeeyul in your IDE. It’s de facto styling code for my IDE and I really like it. I had tried to reuse the same in my E4 Applications and here is how.

1. Add all the 3 plugins required for rendering the CSS to your product features or plugins.

net.jeeeyul.eclipse.themes, net.jeeeyul.eclipse.themes.ui, net.jeeeyul.swtend

These 3 aforesaid plugins have several dependencies.

org.eclipse.jface.text

org.eclipse.text

org.eclipse.ui.editors

org.eclipse.ui.ide

org.eclipse.core.resources

org.eclipse.core.filesystem

org.eclipse.ui.workbench.texteditor

org.eclipse.compare.core

org.eclipse.core.filebuffers

Do add those to your feature or plugin list in Product Configuration.

2. Now, go to your main E4 RCP Plugin’s extension section.

3. You have to add a property to org.eclipse.core.runtime.products extension.

4. The property name: applicationCSS

5. The value: platform:/plugin/[YOUR RCP PLUGIN ID]/css/jeeeyul.css

6. Basically the value points to the specific CSS file that you want to use for the rendering.

Now the question is how would you get the CSS.

7. It’s pretty simple. Go to Eclipse Preferences Section.

8. Go to General -> Appearance -> Jeeeyul’s Themes

9. Now select any of the customised default themes and from the toolbar, click on Show CSS

10. Now copy the whole CSS and save it in the main E4 RCP Plugins’s CSS folder and link it in the step 5.

11. Run and Voila!!!

Sample Code for a Part in Eclipse 4

As stated in my previous post, I have been playing with few obscure things of Eclipse Forms API, JFace and few utility classes to code less. Here is what I have done. For brevity, I am only enclosing the ViewPart code for Eclipse E4.

Eclipse Forms API in Eclipse 4

It’s been a very long time since Eclipse 4 has been released and those ones who are true fan of Eclipse 4 Application Framework might have studied several books on Eclipse E4. But it’s a disappointment not to have any information on Eclipse Forms API usage in Eclipse E4. I have developed a few open source applications using E4 but without lack of inquisitiveness, I have never tried Eclipse Forms in E4 Applications. Since last few days, I have been playing with SWT and JFace for Eclipse 4 and thought of giving Eclipse Forms a go in one of my E4 Applications. And Voila!!!!! It’s working like a champ!! I have throughly rummaged through the internet to garner knowledge on Eclipse Forms API and found some of the best tutorials that can help you use Eclipse Forms in toto.

“SWT and JFace in Action GUI Design with Eclipse 3_0″ - A definitive guide book on SWT and JFace - comprises a separate chapter on Eclipse Forms API

Life at its new

It's been a long since I have written a post by own. Most of all, I share such info which I think to be a novel one or somewhat funny. But this time, I thought I should write something by my own. As you already can imagine, it's all about the recent phase of my life which has had a makeover. If you are finding it difficult to presume or assume it, I would love to draw the line. I am in Munich, Germany for my masters. I have had the admission in the best engineering university in Germany - Technical University of Munich. It's not a pride but a privilege. Let's keep it apart. I would love to discuss some of the things that intrigued to write it. It's all about Germany. First of all, if you think that you can survive here speaking English always, you are wrong then. At least you have to have a basic knowledge of German. I would keep it in tact - A1 level at least so that you can ask for product names if you need ones. I have travelled mostly in Berlin and a few in Munich so far. It's true that Munich is far more happening place that Berlin but Berlin owns the most scenic beauties. It depicts what we see in movies. Apart from it, the commuting system is quite advanced here. People mostly prefer to use the public transport as it is well-connected and very much punctilious. "Irregular" or its german translation doesn't appear in any Deutscher's book. Here it is acutely exact. No delay in its timings. Sound Pollution - what the f*** is that?. I have heard honks once or twice every two weeks. So, if you are honked at, then it signifies the driver is calling you ass-a-hole. Before coming to Germany, I have read somewhere that Germany is a late back country which doesn't like new technologies so easily. But after 2 weeks, I would say no to it as I have seen some restaurants using BitCoins which are pretty new to the world. So, guys please!!! This would be a miniatured version that I loved to share. Hope to enrich it again. Ciau!!

"The" Quote Answer by Krunal M Harne:

Gives me goosebumps every single time I watch it! "Chaos isn't a pit. Chaos is a ladder. Many who try to climb it fail and never get to try again. The fall breaks them. And some are given a chance to climb,but they refuse. They cling to the realm or the gods or love. Illusions! Only the ladder is real. The climb is all there is!" - Littlefinger (S03E06)

https://www.youtube.com/watch?v=xMj-XzmVW4Y

Short version: The climb is a metaphor for achieving power, and the ladder (chaos) is how Littlefinger climbs. When things are in disarray it allows him to manipulate so that he is ahead. Chaos means the great houses overlook his birth, because they need him. It means they are weakened, so they are brought more to his level. Chaos provides opportunities for him to advance, because there are problems to be solved. His strategy is effectively a political version of war profiteering. Long version: Varys said that he does what he does for the good of the realm. Littlefinger said that the realm is a lie, and there is only the individual. Varys says that without a national identity, the people will be thrown into chaos. He compared it to a pit that swallows us all; oblivion that you cannot escape from. Littlefinger then says that chaos isn't a pit, it's a ladder. He contradicts Varys by saying that instead of chaos being something you're trapped in, it's something you use to get out of a pit. It's a way to reach heights that you have not reached before. Littlefinger sets up a dichotomy: While others thrive on order and structure, he thrives on Chaos. Chaos is how Littlefinger advances in society. Now he goes on to explain how people try to climb the ladder (take advantage of opportunities not otherwise open to them) but lack the political astuteness or cunning to do so safely. They "fall", which is to say that they die. Here we see Ros, dead. Another example of this might be when Ned Stark tried to briefly seize power from Joffrey because he was not Robert's true born son, although his motives were far different and he was essentially forced into it. Then Littlefinger says that others refuse to climb at all, preferring safety and comfort -- the realm, Gods, or love. He dismisses these notions as illusions, and asserts that the climb is all there is while Sansa watches his ship. Essentially, Littlefinger is supporting a moral doctrine that says everyone ought to be out for themselves. The only purpose in life is to gain power, and all other things - patriotism, love, religious faith - are lies. Only the accumulation of power is "real" to Littlefinger. And that power can be accumulated through chaos, by using upheaval to rearrange things so that you are on top. Source: Can someone explain Littlefinger's "Chaos is a ladder" speech to me?

Edit:- Two things:- One i am not a stalker of daughters of wealthy business men. I actually googled "best microsoft product" and she was the first result in the images section. After digging into it for 15 mins found it to be one of the biggest lies... It seems on social media, its quite popular for fb pages to put Rachel's photo and caption it as best microsoft product.. Second After going through the suggestion in one of the comments, i looked up the same thing on Bing (search engine owned by Microsoft). But ended up getting very similar results. Only different photos of Rachael Cook. However the actual photo did come up while scrolling down and definitely faster than in case of google.
