Most of my stuffs are in Diigo
Most of the stuffs (technical) that I encountered are now bookmarked in http://www.diigo.com/dashboard/dondonakal
Web 2.1 ??
Watched some good videos about google wave (from google io 2009), and also a video about the history of how the web evolved until now..
Just been thinking if it is possible to create a distributed version control over all the contents (at least the public ones) of the internet?
If the companies out there just somehow stores every version of their websites, so we (as internet users) do not need to worry about stale links anymore as the company stores it along with the new pages..
if the company goes down, then maybe it can submit the contents (public ones) to a public server maybe ??
problems: copyright..

Some improvements of web2.0?
Some improvements of web2.0?
It would be nice if we can somehow add sticky notes to video??And also if there is a website that can process other websites, simplify their layouts so the end users are not trapped within a complex UI...i.e. www.curtin.edu.au I am at lost when navigating the website..a quick look of it will scare me of not finding what i want.

TipsAndTricks
Tips and Tricks for working with Mobile Terminal.
Introduction
This page is a collection of tips and tricks that people have found useful. Please feel free to leave your own in the comments, but put feature requests in the Issues section.
Tips
Hide the Keyboard
Tap twice quickly on the screen to hide the keyboard. Repeat to bring it back.
Control Characters
You can send a control-C by pressing the "bullet" key (First press ".?123", then "#+=", then the circle on the middle right), then press the C key. This can be useful when you want to escape out of a long running program such as ping. Control-C can also be accessed with a short Up-Right and Control is a short Down-Right swipe, after which the cursor will turn highlight red, from here press any character q, x, c, A to complete or the delete button to exit Control mode.
Escape is control-[ or a short Up-Left swip, which may come in handy with vi. Tab is control-I or a short Down-Left swip (yay tab completion).
Swipe Controls
Swipe Type Direction Action
Short Up-Right Control-C
Short Down-Right Control-
Short Up-Left Esc
Short Down-Left Tab
Short up/down/left/right arrow keys (respectively)
Long Up None (functions as up-arrow)
Long Down Enter
Long Left None
Long Right None
Two Finger Up Config
Two Finger Down Hide Keyboard
Two Finger Left Page-Up/Next
Two Finger Right Page-Down/PREV
None of the Two Finger Swipes seem to work right in 2.0 firmware
Multiple Terminals
Terminal comes with four terminal windows. Tap on the battery icon to go right, tap directally on the time to go left, and tap on the carrier name (AT&T or iPod) to crash Terminal (or do a really quick killall Terminal depending on how you look at it).
Things to do with your terminal
While this is in no way a full how-to for UNIX systems, these are some of the commands that you may find useful for your Terminal.
Copy
Usage:
1. cp file /
2. cp -r folder /
3. cp folder /
4. cp -r /folder .
5. cp /file ..
1. Copies file from the current directory to / the root directory
Command cp
Common Flags -r
# Copies the folder "folder" and its subdirectories and files to the root
# Copies the folder "folder" to the root, without its subdirectories
# copies /folder to current directory ( . stands for current directory )
# copies /file to the directory above the current ( .. stands for the directory above this )
Delete
Usage:
1. rm file
2. rm -fr folder
3. rm -r non-empty-folder
4. rm -r empty-folder
1. removes file completely (there is no trash, files deleted with rm are GONE)
Command rm
Common Flags -f -r
# removes folder and its contents recursivly
# this will fail, if a folder has contents you must use -f
# this is fine, it will remove empty-folder
Free Space
Usage:
1. df
2. df -h
1. This will output ...
Command df
Common Flags -h
Filesystem 1K-blocks Used Available Use% Mounted on

Mercurial HG + Tortoise HG + Putty + PuttyLink
Problem cloning HG repo when it is copied from Windows to linux and they have different version:
1. Have a look at .hg\requires file and maybe delete the line that has fncache
2. Try cloning it again hg clone ssh://user@host//path

B2Evolution:
The latest B2Evolution 3.1.0 beta:
- easy to manage the widgets in Blog Settings, can add/remove/reposition/edit the widget.
Edit the widget -> change the text etc
and you can also edit the index.main.php to have what you want.
Doco for skins 2.0 => http://manual.b2evolution.net/Skins_2.0
- i just created a new custom skin, basically copy and paste from custom skin
usermod -G group userid

hg clone ssh://userid@server//path/to/app dirToSave
Putty Tips
> Every time I accidentally press Ctrl+s in Putty when connected to any=20
> Linux box via ssh, my session stops responding. How do I restore it?
Try ctrl-q. If I remember correctly, this is leftover from the old days
when a dumb terminal would send a ctrl-s character if it was receiving
data faster than it could display it, and then send a ctrl-q when it
could handle it again.

b2evolution upgrade to 2.4.5 + mysql bak
Backup your database:
mysqldump -umyname -p b2evolution > dumpfile.sql
Backup your b2evolution folder, copy and paste should be ok.
Then: from /b2evolution/doc/upgradefrom_b2evo.html
Upgrading from a previous version of b2evolution
Before you begin, please note that some network features of b2evolution require you to agree our simple Terms of service.
1. Backup all your b2evolution files. Take special care of the files you may have modified, including /conf, /skins, /plugins, your /media directory and possibly stubfiles, hacks or custom templates...
2. You should also backup your database if you can. This functionality should be provided by your host.
3. If you are upgrading from a version prior to 2.0, we highly recommend you clean up outdated files. To achieve this, delete your b2evolution folders except /media. Folders to delete include /admin, /conf, /cron, /htsrv, /inc, /install, /plugins, /skins, /skins_adm, /xmlsrv. Depending on your version, you may not have all of these folders on your server. Also, again, make sure you have a backup before deleting.
4. Upload all new b2evolution files from the /blogs folder to your site. We cannot stress this enough: ALL FILES! And that means you cannot reuse your /conf files, default skin templates or default plugins as they are.
Since your custom skins and custom plugins should be using different names, they will not be overwritten. Same for your media files.
The one file you must absolutely restore from your backup (see step 1) though is /blogs/conf/_basic_config.php. You will need to either restore or recreate that file in order to proceed with upgrade.
5. Run the installation/upgrade script on your server. It is located in http://yoursite.com/yourblogsfolder/install/ . Then, simply follow the on screen instructions.
The installer/upgrader will allow you to run a database upgrade from any b2evolution version to the new one.
6. Check to make sure the new installation works.
7. Check the online manual for specific upgrade instructions to your new version of b2evolution.
8. On production servers, it is recommended that you delete the /install subfolder.
9. If you had hacks or other customizations to the core files, your can bring those back now. We recommend you get yourself a diff/merge tool like WinMerge. This will allow you to easily compare your old (backuped) files with the new files (even whole directories at once) and report changes accordingly.
The next step is to upgrade the skins..

ORCA is LIVE
ORCA is finally live!!
http://www.orcacard.com/ERG-Seattle/p1_001.do
After years of waiting, finally the Seattle community can buy smartcards to be used in the public transport system from www.orcacard.com
You can buy cards, register them, add products into the cards, configure autoloads and so on.
This is also a huge accomplishment for ERG, the software provider.
orcacard is one of the two public websites, where the other one is for the institutions like Boeing and Microsoft.
Another two websites are private, they are for the agencies and call-center.

b2evolution
I am trying to fix problem on b2evolution 1.9.3 where the admin user cannot review a new post.
scenario:
1. Write a new post,
2. Then click review.
Instead of showing the review, it will return to the blog, as if I click "Exit to blog" link.
There are about 6 blogs in the same domain and only one has this problem.
This happens every time I try to login as admin where the path to index php not does have the blog id as parameter, i.e.
it works if I login like this www.mysite.com/blogs/admin.php,
but it does NOT work if I do this (clicking the login button) www.mysite.com/blogs/employee/index.php?blogID=3
Still trying to fix this problem

Internet explorer does not display *.ico file
internet explorer does not display *.ico file when it is not in the correct icon format (png, jpg, gif, etc, read http://www.gtalbot.org/BrowserBugsSection/MSIE7Bugs/ and http://blogs.msdn.com/jeffdav/archive/2007/03/01/why-doesn-t-the-favicon-for-my-site-appear-in-ie7.aspx ).
It has to be in the proper ico file, so you can use free icon editor such as IconFx http://icofx.ro/ to edit your icon file and save it as proper *.ico (16x16).

Using IETester to simulate IE5.5, 6, 7, 8
I used IETester to simulate IE5.5, 6, 7, 8 java script engine, to prove that an issue originated from the usage of IE8.
IETester is quite easy to use, altough I don't know where to setup the compatibilty option (Tools > Compatibility View Settings in IE8)..

New software
I am surprised to find out how easy it is to browse the web using Opera browser. You can easily navigate through the links using Shift-Up/Right/Down/Left.
And if you minimize the browser, it trims its memory usage way down (typical of .Net WinForm application). I am not aware if this behaviour is available in Firefox or Google Chrome.
Now I can surf the internet without touching my mice at all!!
Also I am disappointed that Altiris SVS does not run under 64 bits OS..how painful it is..

SQLServer_2005 + VisualStudio_2008
*.mdf file can be used as a database replacement (you do have to install SQLServer to access the mdf file).
Just be aware that the log file *LDF must be deleted every time a new *mdf file is deployed. Otherwise the connection cannot be established.

Grails + Acegi + IntelliJ
- Create new Grails application project.
- Create a new domain class using 'grails create-domain-class domain' and make sure the name does not have 'order' in it. For some reason, the IntelliJ generated domain is not recognized as a valid domain class by grails.
- Added some fields to the domain class
- Generate the Controllerclass using IntelliJ (grails create-controller script is not good enough)
- Modified the 'def index = ...' into 'def scaffold = ...'
- run-app
- grails install-plugin acegi
- grails create-auth-domains User Role Requestmap
- grails generate-manager
- grails generate-registration
- grails run-app
- Create userroles : ROLE_ADMIN and ROLE_USER
- Create user: admin with ROLE_ADMIN and user with ROLE_USER
- Create mapping: i.e. /Inventory/** for ROLE_ADMIN
- grails run-app
To enable HTTPS:
basically:
- grails install-templates, ( the following code is generated from http://www.simplebits.com )
<filter>
<filter-name>Acegi Channel Processing Filter</filter-name>
<filter-class>org.springframework.security.util.FilterToBeanProxy</filter-class>
<init-param>
<param-name>targetClass</param-name>
<param-value>org.springframework.security.securechannel.ChannelProcessingFilter</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Acegi Channel Processing Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping> - Navigate to the src/templates/war and add the filter to the web.xml template there:- This following code should be put into yout grails-app/conf/spring/resource.groovy file (the entire file is reproduced here):
import org.springframework.security.securechannel.ChannelProcessingFilter
import org.springframework.security.securechannel.ChannelDecisionManagerImpl
import org.springframework.security.securechannel.SecureChannelProcessor
import org.springframework.security.securechannel.InsecureChannelProcessor
// Place your Spring DSL code here
beans = {
secureChannelProcessor(SecureChannelProcessor)
insecureChannelProcessor(InsecureChannelProcessor)
channelDecisionManager(ChannelDecisionManagerImpl) {
channelProcessors = [secureChannelProcessor, insecureChannelProcessor]
}
channelProcessingFilter(ChannelProcessingFilter) {
channelDecisionManager=channelDecisionManager
filterInvocationDefinitionSource='''
CONVERT_URL_TO_LOWERCASE_BEFORE_COMPARISON
PATTERN_TYPE_APACHE_ANT
/**=REQUIRES_SECURE_CHANNEL
'''
}
} - grails run-app --https
