Learning #0009 - Web development

Ctrl + Shift + T - Shortcut in Google chrome to open the Recently closed tab
I will have to remember such shortcuts, considering how stupid my habits are. Shucks..!!

MS SQL Server Authentication
In a application with loads of java, dojo and what not code, we were using MS SQL Server for our database. We were using weblogic as the server for deployment. I normally start the weblogic server and when I see the "RUNNING" text in my command prompt, I am happy to go browse the application. However this time it did not happen so. Puzzled and nervous that I am always, I panicked and did not know what to do. Restart of server did not help. I then checked the weblogic console and looked for deployment tabs and all the Data sources were showing failed. I then tried to log in to the MS SQL server and it did not allow me to login. I was surprised, since the database were on my local machine, the SQL Authentication should have succeeded. Google to rescue. I learned that the SQLEXPRESS service needs to be in running state. Navigated to services.msc and enabled the MS SQL Service. Crap load of time wasted.

Learnings #0008 - Web development

Chrome - Execute JavaScript inside an iFrame
Recently I tried to console a piece of javascript in console but it returned undefined. Later realized that I was working in iFrames and the Javascript was more related to the content frame instead of the top frame. Was surprised to see that chrome has a freature in console that let's you choose which frame you want to execute your javascript command in. Pretty neat!!!

All this while it was seating next to the clear button, but never noticed. Below is the screenshot




It's important that you put the JavaScript after your HTML div container.
I forget it most of the time. Well working on an existing application, where the script is placed right above in head somewhere. In my defense, I am used to working on application where javascript is placed right at bottom just above closing body div. So issues like this never suffice. However, note to self, always think about the issue and its root cause before jumping on to Google for a solution.

document.getElementsByClassName and document.getElementsByTagName returns an array
Can literally see in the console that it returns of type array, but sometimes we just cannot get our head around it. Feel ashamed due to my limited knowledge. jQuery has made me handicap.


document.getElementsByClassName("someClass")[0].innerHTML = "Yes, I will be changed";

same with

document.getElementsByTagName("strong")[0].innerHTML = "Yes I am Bold";

Strange padding error in table
So clicking on a tr should hide and show another tr was the scenario. This was done in long time back and the way the animation was achieved was incrementing the height of the content tr using setTimeOut javascript function. The main td had padding of top, right and left 20px and the bottom padding was 0. However the td inside the main td had bottom padding so the design looked a little even.

When clicking on the title tr, the body tr should collapse and hide. Just like an accordian. And to achieve this, a height was being applied dynamically to the body tr. Since an inline css for height was being applied, somehow, the padding was applied to even the bottom. And now, since offsetHeight of the body tr was being calculated, it would calculate inclusive of the padding bottom. Strange situation and I still have no clue if my analysis are correct and justifiable. However in the interest of time, I removed any CSS applied to the main body td and applied padding to the data that was inside that main td. I know, quite a mouthful but solving this issue was quite a feat considering how dull I had been with CSS for fast so many months. After writing it down here, now I feel I have achieved something.

What is Creative State of Mind?

Excerpts from a book I was reading, loved it, so posting it here.

What is the creative state of mind?
It is, one whose interest in what is being done is wholehearted and total, like that of a young child. With this spirit, it is always open to learning what is new, to perceiving new differences and new similarities, leading to new orders and structures, rather than always tending to impose familiar orders and structures in the field of what is seen.

If one will not try anything until he is assured that he will not make a mistake in whatever he does, he will never be able to learn anything.

Creativity Now: Get Inspired, Create Ideas and Make Them Happen! - Jurgen Wolff

The book was very colorful. Also, it was about creativity and I thought why not? I have read a lot about such topics and many times have practiced some of the methods, but alas, I wanted to read it.


Creative Success Manifesto
1) Success is what you say it is.
2) Commercial Success can take a year or hundred years.
3) Fewer than 1 percent have to buy what you do. Start by finding one person who likes what you do.
4) Crazy is the first step.
5) Ready, fire, Aim.
6) If at first you don't succeed, don't try, try again.
7) Failing feels crappy.
8) The only way to fail if you stop.

For eg, you might give a lesson on how to be late, how to over eat, how to make sure you never exercise, how to procrastinate or just about anything. Once you are done, what you have to do is just opposite of what you taught yourself.
