Mind Map In Software Development

After a few days of brainstorming + paper + pencil, I still fail to generate a concrete idea on the overall implementation of upcoming JStock's feature.

I realize that there is a technique, to organize and stimulus your idea. It is called Mind Map.

It seems weird at first look, to organize your idea in such a way. However, I do give it a try by using FreeMind.

Just after one and a half hour, I am able to draft out a big picture of the feature.

It seems that as you trying to break down your ideas into smaller chunks and document them down, more new ideas will be stimulus.

Great! Isn't it?

Configure TortoiseCVS to Access Sourceforge through SSH In Windows Vista

All the while, I have been using SmartCVS to access sourceforge CVS repository. SmartCVS is really a nice piece of CVS GUI client software. It serves all my need for my day to day CVS operation. However, I am using free edition (please forgive a poor free software developer), and free edition comes with the following limitation :

1. No conflict solver feature.
2. No branch merging.

Since I start to apply branching in my sourceforge project, free edition SmartCVS no longer serve me well. Another free alternative, TortoiseCVS came to my mind. I had tried to use this software few years ago in my Windows XP, and I am happy with it too.

Now, I am using Windows Vista. I thought TortoiseCVS shall able to work well in Vista too. However, I get the following problem while using TortoiseCVS :

TortoisePlink.exe keeps on crashing

After several hours of configuring, I was finally success to perform the following task :

Use TortoiseCVS to Access Sourceforge through SSH in Windows Vista

I would like to share my experience, in case anyone of you need to perform similar stuff as me.

1. Download pageant.exe, plink.exe, putty.exe and puttygen.exe from here. When the time I download, it was version 0.60. I locate all the 4 exe files in c:\putty
2. Launch putty.exe. You will see the following screen. Click on "Generate"
3. 
4. Keep moving your mouse randomly as instructed by putty.exe. After a while, you shall see the following screen.
5. 
6. Click "Save private key". I save it in c:\putty, as file name "C:\putty\SourceForge-Shell.ppk".
   
7. Then select all, and copy text under "Public key for pasting into OpenSSH authorized_keys file". The public key information will be later used to submit to sourceforge server.
   
8. Go to "Control Panel" -> "Adminstrative Tools" -> "Task Scheduler", add the following new task. This is to make your Vista auto load private key through pageant.exe, each time you log on to Vista. We want the following command to be executed. "C:\putty\pageant.exe C:\putty\SourceForge-Shell.ppk"
   
9. 
10. 
11. After you restart your computer, you shall able to see the following spy agent liked icon in your system tray. (OK, I know you are trying to figure out what Anti-Virus I am using, who cares?)
    
12. 
13. Now, we want to send the public key information in step (7) to sourceforge. Go to your personal page in sourceforge.
14. 
15. Go to "Account Options", then scroll down until you see "Host Access Information". Paste the public key information and save. Note that, the entire public key information shall be in 1 line.
16. 
17. Right click on your desktop, go to CVS-> Preferences. Change your SSH application to c:\putty\plink.exe and SSH parameters to -l "%u" "%h"
    
18. 
19. Now you may check out your sourceforge project, and start to hack on it :)

Feature [2676553] On The Way

Today, we plan to start work on feature [2676553]. This will be the key feature for our very exciting next major release - 1.0.5

First, I decide to review our "two-dimensional graphics framework" library. Currently, we are using JHotDraw. After several consideration, "stability", "requirement", "compatibility", we decide to stay on JHotDraw.

I foresee that we will be required to work on JHotDraw source code, either understand it or expanding from it. Hence, grabbing out the right JHotDraw source code is another big task.

Our previous JHotDraw version is 7. However, I have a hard time to figure out the minor version of current deployed JHotDraw. After some try and error, I decide to give up figuring out current JHotDraw minor version.

I decide to first port over JStock source code, to make use of latest JHotDraw 7.1. The latest stable version of JHotDraw 7.1 is released since 2008-03-25.

After building JHotDraw 7.1 together with quaqua.jar, java_30.zip and MRJAdapter, we obtain a hot baked JHotDraw 7.1. When run it together with JStock 1.0.4b, opps...

Unhappy OSX User

It seems that we are having some unhappy OSX users.

https://sourceforge.net/forum/forum.php?thread_id=3103567&forum_id=723855

As hard core Windows user, I do not own any OSX to reproduce the problem. Hence, I decide to setup a virtual environment for OSX, by using VMWare player. Just like what I had done to test JStock for Ubuntu Linux, under VMWare player.

Unfortunately, OSX under VMWare player is much more resource intensive than what I am expecting. Moving a mouse pointer, click on the Safari icon, take 1++ minute to launch the browser!!!

After several tries, I decide to give up the idea of perform testing under VMWare. OK, I would like to invite OSX packager to join JStock project, as posted here and here.

Anyone?

Further Addon Plans for 1.0.4b

During the development of 1.0.4b, we discover other bugs which may make our end users unhappy.

[2687975] Wrong Information Displayed For Korea Market

Hence, we decide to mark this as "Must Fixed", before we are losing potential Korean user.

Interesting Blog by Joshua Bloch

I have been reading an interesting blog by Joshua Bloch, Extra, Extra - Read All About It: Nearly All Binary Searches and Mergesorts are Broken

The following solution can be found in latest version of JDK

int mid = (low + high) >>> 1;

The first thing which comes across my mind is that, (low + high) will cause sign overflow too. However, the comment from the following reader clears out my mind.

">>>" is the unsigned right shift operator. So if I'm not mistaken (low + high) is stored in unsigned int and then shifted one to the right dropping remainder leaving a division by 2 with no remainder returned as a signed int. So it does work.

Very cool, isn't it?

Patches and Minor Fixes Planned for 1.0.4b

The release of 1.0.4a had been locked down. This means there shall no be any further major enhancement and major bug fixing for 1.0.4a. All the major enhancement and bug fixing will be going into release 1.0.5.

However, patches and minor bug fixing will still be released along the line 1.0.4b, 1.0.4c…

After the few hours released of 1.0.4a, 3 minor bugs (which doesn’t not have large impact to the end users) had been identified :

(1) False alert being received in “Fall Below” - The plan to fix this is to include more detailed in the email sent out by JStock, in order for developers to track down the problem

(2) NPE while changing country - This shall not have the major impact, as NPE is caught at Swing Event Dispatch level. However, there shall not be any NPE thrown.

(3) Two country channel displayed at the same list box while changing the country. There should be only one.

Developers are now working on to resolve the problem. All the above mentioned problem are targeted to be released at 1.0.4b

11 New Countries Support In 1.0.4a

Due to request from users, the following new countries had been added in version 1.0.4a

- Australia
- Austria
- Belgium
- Canada
- HongKong
- Indonesia
- Korea
- Netherlands
- Portugal
- Switzerland
- Taiwan

Thanks to the well design abstraction employed by JStock. All the new countries can be easily added within a night, with not much difficulty encounter ;)

Welcomed to JStock Development Blog

The development goal for JStock 1.0.5 had been defined :

Further enhance usability of Stock Indicator Editor.

Two feature tracker had identified with highest priority :

[2676553] Complex Operator composed of Primitive Operator
