TIOBE Index: How popular my programming language skill?

It is too bad for me which in last 8 years I'm too focus on specific skill.
I have been far away from my passion, programming. 
In recent day, i've done some research on the trend of programming language. Search and read many article over the net. and I found this, www.tiobe.com. TIOBE is company which specialized in assessing and tracking the quality of software.
What interesting to me  is, this company site, by monthly, release the rank of programming language popularity. It is officially call as  TIOBE Programming Community index. The ratings are based on the number of skilled engineers world-wide, courses and third party vendors. Popular search engines such as Google, Bing, Yahoo!, Wikipedia, Amazon, YouTube and Baidu are used to calculate the ratings. It is important to note that the TIOBE index is not about the best programming language or the language in which most lines of code have been written.
The definition of the TIOBE index can be found here.
Rating mainly defined base on the search engine. It mean, higher rank of programming language on that TIOBE Index, that programming language more demanding.
For university student, for instance, it can be used to decided which programming language that they should learn.
For educational institution, it can be used for planning their curricula.
Software house and vendor also can used what their programming language and technology that they are focused in the future. 
And so on.

But please note. 
There are many parameter for that above decision to make. You cannot simply use that Index.
You should take attention on old programming language which has good position on the index, Visual Basic (rank #9) and Delphi (rank #11).
With top 20 position for VB and Delphi, it is very interesting discussion, is history repeated?

HTML 5: Why you need HTML 5 ?

There are many of blog and article the explain, in-details, why you should use html5.
I'll give you the link on the end of this article.

Before answering the the question of this article title, let me share what it HTML5.

HTML5 just new HTML specification on top of previous version of specification.
If you have knowledge and experience on html 4, that enough to moving forward.
It come with some new tag that mainly to offer more rich of web application development.

So, why you need HTML 5?

1. It bring new tag with rich content capability. You can have audio, video content with our 3rd parties plug-in need to installed (use <audio> and <video> tag). even it is possible to built game application using <canvas> tag 
2. Code is cleaner. instead of using <div> tag with id then manipulate the content using javascript, html5 come with specific tag. <section>, <article>, <header>, <footer>, <aside> and <nav> tags will give you more meaningful tags. 
3. It is mobile ready. Mostly no need special converter code to display web application on the desktop browser or mobile. it just ready!
4. No more painful with 3rd parties plug-in. use pure html which will support by cross-platform browser. include geo-location API.

Here some more details article for future reference.

HTML 5: Brief of AJAX

In 2005, Jesse James Garrett, publish a blog Ajax: A New Approach to Web Applications, which realize (as many others) the gap between web-base application and native-pc/desktop-application and he think that gap is closing. He gave example for Google Suggest and Google Map application.

That two Google application, that time, was new approach to web application, as he call as AJAX, Asynchronous JavaScript And XML.

"Ajax isn’t a technology. It’s really several technologies, each flourishing in its own right, coming together in powerful new ways"

So refer to Garret, AJAX consist of:

• standards-based presentation using XHTML and CSS;
• dynamic display and interaction using the Document Object Model;
• data interchange and manipulation using XML and XSLT;
• asynchronous data retrieval using XMLHttpRequest;
• and JavaScript binding everything together.

Web application, work base on http request and response.
For instance, you click one link or click submit button of web page, it is actually request data to the server, then server will response by sending bunch of HTML code.

In traditional web application, the response from the server will replace, entirely, the HTML code for one page. for example, your page contain data 1,2 and 3. You send request to the server to update data 1. if you want your page also contain data 2 and 3 for next response, you have to request data 2 and 3 as well. it is synchronous.

Using AJAX, you can request only data 1, then data 2 and 3 which already on the client (browser) no need to be requested again. Data 1 will updated on specific area of your page, the rest still untouched. it is asynchronous.
AJAX will reduce number of traffic between client and server, which on above example only data 1 will be transferred.

If you are an active user of Facebook, you will notice, receive friend request without even click any button. Asynchronous method on AJAX will check on the background to the server if there is new friend request to you.
And friend request notification only displayed on particular area of your page.
Amazingly, you can response to that friend request without refreshing entire your Facebook page.

It pretty same as native application behavior. it is bring user-friendly web application.

eureka!
Then why you still need HTML 5?

HTML 5: Flash back

In the late 90's, Web-based application got their momentum to grow. 3-tier application offer the most significant benefit to the software development: 

• No need to install native application (just use the browser), no painful to install and update on each client machine
• Cross platform (Build Once, Run Everywhere)
• Maintenance on the one place (on the server side)

With above advantage, many new web-based application was released. It also attract existing native-application to migrate to web-base application.

Beside that advantage, actually the web-base application has some challenge:

• Most of pure web-base application is not intuitive as native-application
• it is not easy to build user-friendly web-based application as native-application does. need extra man-days labor cost. 
• Cross-platform jargon not always work (browser's vendor sometime build non-standard tag, or new version of specification) 

Then Dynamic HTML come to the picture.

Which seem promising to build intuitive, user-friendly web-base application,

Javascript, VBScript, DOM and CSS (cascading style sheet) technology combine with static HTML. 

But, as you remember, big vendor bring their own specification. Microsoft with JScript and VBScript, Sun microsystem with javascript.

Regardless of vendor competition, dynamic HTML also still have drawback to bring rich content, intuitive web-base application. It is dynamic, yes. But only happen at the client side. You can have beautiful-dynamic looking web application, but cannot interact dynamically with server side.     

I have no idea when it is exactly started, instead of focusing to enhanced the dynamic html specification, some vendor come with browser plug-in/adds-on.

Plug-in is native application that can be embedded and run on the browser.
It is just pure native application! 
Sun Microsystem come with Java Applet, Microsoft with Active-X and one phenomenon is Flash Player from Macromedia (later Adobe).

Plug-in offering something that pure web-application cannot do - rich content, intuitive-user friendly application.

But again, it also bring objection, in-term of performance and security.
And the technology is proprietary to specific vendor (even Java claimed as 'open').

Here some objection on that Plug-in/Adds-On technology:

So, what next?
AJAX ?

Extreme Programming: How are you, Bro?

It quiet long time i didn't follow what happen to extreme programming (XP) methodology progress.
Since i leave my main jobs as developer in 2006, I have no practical and technical practice on XP.
I tried to do some small check on the search engine, with extreme programming keyword.
That bring me to main extreme programming site, www.extremeprogramming.org

I've checked, last update on that site is on 2009! that's five years ago.
Ok, may be the admin site was like me, move to another jobs and nothing special can be added to the site so far.

Search another site, found some site the referring to Don Wells, XP Guru and initiative who the owner and host of www.extremeprogramming.org.
it lead me to http://www.agile-process.org/ and Don is there!

Agile is core, main soul of extreme programming. XP for whatever reason it is named, seem didn't attract big software vendor to use it.
Agile is more general too, simple and easy to associate with only by referring the terminology.
On some presentation, in my company i work for now, Agile is marketing booster key-word too.

Continuously improvement by Agile.

XP body may be dead, but the soul, it reincarnate to better form, I believe.

HP OMi 10: opr-jobs command to manage deployment jobs

HP OMi 10, with Monitoring Automation feature, designed for Automatics policies assignment and Deployment.

But for some reason, sometime deployment jobs if fail due to agent connection problem for instance.

Even after agent connection establish , when deployment jobs fail, you have to restart the deployment jobs through GUI: 
Administration => Monitoring => Deployment Jobs
then select failed jobs, right click and restart deployment jobs.

there is alternative way to managed redeployment jobs using command line: 
<BSM_HOME>/opr/bin/opr-jobs.sh | bat <conection> -start

here the example:

If you want only redeploy failed jobs, use following:
<BSM_HOME>/opr/bin/opr-jobs.sh | bat <conection> -start failed


HP BSM

HP OMi 10: New version. What new and impact on the architecture?

Early this year, HP has released new HP Operation Manager i 10 which bring new architecture for Operation bridge families of HP Software.

http://www8.hp.com/us/en/software-solutions/operations-manager-i-operations-management/try-now.html

The main thing that shipped with this new version are:

• OMi now separated from BSM. BSM will mainly focused on the Application Performance Management (APM). A long with OMi 10 release, HP APM 9.25 also released.
• Monitoring Automation (MA) also will shipped together with OMi 10, no need separate installation to get MA feature on the OMi 10, like on the BSM 9.2x.

What the impact on your architecture?

Here I'll only discuss on the new deployment of the OMi. Later on, I plan to post the impact on the existing BSM/OMi/MA/OM deployment.

Why you need OMi?

That the first question that should come on your mind to decided for deploying of OMi.

OMi is designed as single event consolidation dashboard. You desired to have single pane of glass for events.

You have multiple events source which need to be consolidate and correlated. That is the perfect scenarios to bring OMi.

OMi naturally will consolidate Agent base event (from HP Operation Manager) and Agent-less event from SiteScope for Server and Application event.

OMi has integration with NNMi for Network base event which will give you much visibility on your entire infrastructure events.

Also, OMi shipped with various BSM Connector, to integrated third parties EMS:

IBM Tivoli

Zenoss

BMC Impact Manager

VCenterOps

Nagios

SCOM

What is Monitoring Automation?

Monitoring Automation which introduced on HP BSM 9.22, bring capability of BSM/OMi as Management Server, like HP Operations Manager. 
Yes, you can create monitoring policies, deploy policies,upload instrumentation and update installed Operation Agent.
And also for SiteScope (Agent-less)
Even more...AUTOMATION. I'll post another topic related to Monitoring Automation

What impact on your new deployment architecture?

By design, OMi 10 now is HP BSM with focused on Operation Bridge, and Monitoring Automation. Completely separate from HP BSM/APM.

You'll not found following feature when installing HP OMi:

• End User Management (HP BPM or HP RUM)
• Service Level Management
• Diagnostics
• System Availability Management (SiteScope UI), but you still have Event/Topology integration, and SiteScope monitoring configuration via Monitoring Automation.

On OMi 10 you will have:

• Operation Management complete feature (event browser, TBEC, SBEC etc)
• Service Health
• MyBSM (renamed as Workspace) and its component plus OOTB Pages
• RTSM as Foundation configuration management

How I can get complete feature of BSM 9.2x on OMi?
Integration. You can integrate HP BSM 9.2x/APM 9.2x to OMi 10 get complete feature.
End user monitoring event and HI can be sent to OMI.
Event from OMi can be sent to APM 9.2x to feed SLM.
I also plan to post on separate topic for OMi - APM integration.

Note: for future, I'll use APM instead of BSM.
