How Do You Keep Up With New Technology

I found interesting opinion in my favourite blog www.37signals.com about how can we learn about something new without spending all of our time in front of computer.

Here is the story :

Someone ask to 37signals

As a developer, I often feel overwhelmed by the amount of new technologies and languages to learn. I work long hours as it is, and the last thing I feel like doing when I get home is spending more time trying new stuff out at the computer. Do I really have to be the kind of person that is excited about spending 24/7 at the computer to be a programmer? I love my job, and I love what I do, but I want a life outside of it too.

And 37signals answer

The best way to learn new technologies is on the job. I learned Ruby because I wanted to escape the pain that PHP and Java was giving me and because I had a fresh project to try it on (Basecamp). I built Rails because I needed it for Basecamp. I got into Ajax because we wanted to give Ta-da a compelling UI experience. I got into REST because we didn’t want the API for Highrise to be an afterthought. I picked up on OpenID because the thought of building single-signon for all 37signals’ products sounded like a drag to build from scratch.

As a developer  i had same problem too. But i have the same opinion with this. I think the best way we learn is in our job. 
Believe or not we spent most our time in our office doing our job.
 

Excel 2007 Bug With Multiply

This bug came when you multiply 850 * 77.1
Excel 2007 result is 100.000
The correct result is 65.535

For now, only those number give the wrong result, but we don't know yet if other number can give us same error.

How Adsense Scripts Works

Do you wonder how Google Adsense scripts work. I mean this is just script, how can shows up relevant ads to our website.

I'll try to explain the secret of Google Adsense Scripts, show_ads.js

Before we continue, it's important to you understand this article for education only, not for hacking Google Adsense Scripts. You break ToS GA if you do that. We are on the same page now ? Ok good.

Google Adsense Script (show_ads.js) maybe protected by Obfuscator to make the script hard to read. I need a lot of time to reformat script and rename variabel based on my logic.

How Google Adsense Scripts work ?

(script type="text/javascript")(!--
google_ad_client = "pub-71209491204xxxxx";
google_ad_width = 180;
google_ad_height = 150;
google_ad_format = "180x150_as";
google_cpa_choice = "CAEQyvTH1QMaCLmcVsXlpQobKILJ0s0BMAA";
//--)
(/script)
(script src="http://pagead2.googlesyndication.com/pagead/show_ads.js" type="text/javascript")
(/script)

Notes : I've changed <> to () to prevent ads shows up in this post.

Look at script beginning with "google_" thats is parameter sent to show_ads.js to build a large query string to server, and server returning back by showing ads. By default you can't modify script unless you are premium publisher like slasdot.org.
There is no different script between premium publisher and normal publisher, we using the same script, show_ads.js. The different is normal publisher DISALLOWED to use all parameter in show_ads.js

SLF4J

Here is announcement for SLF4J (Simple Logging Facade for Java)

The Simple Logging Facade for Java or (SLF4J) is intended to serve as a simple facade for various logging APIs allowing to the end-user to plug in the desired implementation at deployment time. SLF4J also allows for a gradual migration path away from Jakarta Commons Logging (JCL).

SLF4J API offers an advanced abstraction of various logging systems, including JDK 1.4 logging, log4j and logback. Features include parameterized logging and MDC support.

Logging systems can either choose to implement the the SLF4J interfaces directly, à la logback or SimpleLogger. Alternatively, it is possible (and rather easy) to write SLF4J adapters for a given API implementation, e.g. Log4jLoggerAdapter or JDK14LoggerAdapter..

Close Window Browser Without Warning

How can you close window browser without get warning message like this
"The page is trying to close the window." ?  This warning message shows up when you use Java Script syntax window.close(); or self.close();
window.close() checks window.opener. If "opener" equals empty string it suspects that we talk about parent window (not the one that was opened with window.open(...)) and pop-ups warning.

So we use this simple function :
// Work with Firefox, Netscape, IE, Opera
function closeWithoutWarning()
{
    window.open('','_parent','');
    window.close();
}

// Work with IE
function closeWithoutWarning2()
{
    window.opener = "whatever";
    window.close();
}

Netbeans IDE To Become GPL

Joshua Marinacci has posted blog about Netbeans to become GPL. NetBeans will be released under the GPL v2 with Classpath Exception.

What is that mean ? Classpath exception means that using Netbeans RCP would not require your application to be GPL too.

Joshua said it hasn't happened yet, but it's official and it's definitely going to happen.

My Google Adsense Pin Finally Arrived

Horrayy...

After 3 month blogging, my adsense account reaches more than $50. According to term & condition of GA (Google Adsense), when i reaches $50 for the first time then i should get my Google pin to get my first payment.

Source Code Line Counting

You are the Project Manager and you just finished your project on time. Now you want to bill customer based on LOC (Line Of Code) of your project. What you gonna do ? Open all of your source code and counting manually ? Thats a bad idea.

The smart idea is using Practiline Source Code Line Counting program. Its not free, but it give you 15 days trial. The following are the feature of this program :
*. Choice of folder and addition of files from the program without additional dialogues;
*. Simultaneous support of all format types;
*. Free selection of available formats;
*. Definition of file format by its type (extension);
*. Advanced report export (printing, saving as pdf, doc and other formats, copying to clipboard)
*. Saving and loading of profiles for various users;
*. Displaying available profiles as menu;
*. Full report on the code:
*. number of source code lines;
*. number of blank lines;
*. number of comment lines;
*. number of mixed lines (code and comments);
*. percentage of comments, blanks and source code;
*. Sorting the report by any column of the table;
*. Copying a selected part of the report to clipboard;
*. Counting totals in the report (sum total, percentage).
Download program here

Okay now the problem of counting source code text based file (Java file, C++ file, PHP file, etc) solved. BUT what about counting line of code PLSQL code ?
Thats piece of cake, try using code

SELECT SUM(LOC)
FROM
(
   SELECT MAX(line) AS LOC,NAME FROM ALL_SOURCE WHERE owner='QUEST'    GROUP BY NAME
)

Thats it. This article should help you to do line counting.
 

Support Issue In Open Source

Matt Asay wrote the article about support issue in open source.

The point are :
1.  

The research revealed something that I suspected but had not yet seen data to prove: developer communities are great for developers, and not so great for anyone outside them.

What does this mean if you're an enterprise hoping to hitch a free ride on an open-source project? Well, it means that you're better off paying a little money for professional support. Free support is good up to a point, but if that point ends when your job begins, you may be in a world of hurt without it.

 Well i totally agree with his statement. Free support is bad, i mean without paid 
developer of course don't want wasting time to give us support. They only give us support in forum while developer answer that if they had time.

2. Fact case study comparison free support and paid support
Free

* Studies utilizing developer mailing lists show that only a handful of core and active developers discuss code development (Barahona et al., 2004; Mockus et al., 2002) , with very little discussion on some of these lists (e.g., the Apache web server list). You're either in the know, or you're not, apparently.

* Lakhani and Hippel (2003)...found that ~2% of the knowledge providers were responsible for about 50% of the answers to questions posted on the help system and 50% of the questions were provided by 24% of the knowledge providers. [In other words, you get a lot of mileage out of just a few people - in terms of resolving questions and in posing questions - and most others are along for the ride. On Apache, especially, only a few people actively answer questions on the list.]

* Krogh et al. (2003) found that 36.7% of new participants [to the developer, not user list] got no response to their questions. [Apparently, the best source of support will not be a pure community.]

Paid

Studying the Debian mailing lists, Sowe et al. found that] [i]n the Developer list participants contributed more replies (mean = 34.52) than posts (7.95). The reverse was the case in the User list. Participants posted more than they replied to questions asked in the list. One explanation for this could be, as Mockus et al. (2002) discovered in the developer mailing list of the Apache project, postings in the developer lists may contain sufficient information to allow others to comment on them...[whereas the user questions are not considered interesting or informative enough to warrant a response.

Mmm i don't think so, say if developer don't wasting time to support, then they can gather community to help newbie user. For example Hibernate forum, Ruby forum.

Grails vs Rails Productivity Comparison

Many people that using Rails claim that Rails save a lot of effort and increase productivity. With Rails, we can boost "speed of development".

So far many people believe on that statement.

But now there is someone claim Grails is more productive.

AfterThought who wrote this comparison is a consulting company that developers Web applications and distributed systems, is currently doing a project for a Fortune 200 company that was begun on May 30th of 2007. The company did estimates of the amount of effort required to do the project in J2EE, Java/Spring, Rails, and Grails. The numbers they came up with, using a planning tool called Planix (which they have used for several years), looked like this:





In my opinion, this comparison not based on fact. Look at the chart, only Grails is provided actual data, the other just estimate. Its mean they don't try build the same application using Rails. I wondering how they made the estimate.
