HOW TO : Clear saved username/passwords in Windows
I came to know this method, when I saw one of the IT techs use it to troubleshoot some Internet connectivity issues.
To clear any saved username/passwords (i.e. Internet Explorer, Windows Explorer etc) in Microsoft Windows, do the following
- Click Start –> Run, and type in
control keymgr.dll - Delete any entries you want to from the list
- Click on close
I tried this on Windows XP and Vista.
I am in the Guinness book of records.
And so are 8 million other people!! :). Here’s a picture of the official certificate from Firefox showing that I was part of the world record for the most downloaded software in a 24 hour period.
HOW TO : Configure JBoss to follow symbolic links
Jboss, in addition to being an application server also serves static content. We recently ran into an issue where some static content was not displayed when users hit the link. The JBoss server kept spewing 404 errors, stating that the content was not found. On some hair pulling research, we figured out that JBoss, like Apache, does not follow/allow content mapped to a symbolic link.
So for example in your web app, you added a sym link to another directory, where most of your content is stored, Jboss would not show the content, when you go to the link.
Here’s a quick guide to fix this.
- Go to the deploy folder of the context you want to configure. For example, if you used the default context, you go to $JBOSS_HOME/server/default/deploy/jboss-web.deployer
- Edit the context.xml file and add allowLinking=”true” in the Context (NOTE : This allows Jboss to publish symbolic links on all apps in your application server, if you want to restrict it to just one particular app, you have to edit the context.xml in your specific application folder). Upon adding the option, our context.xml file looked as such
org.jboss.web.tomcat.security.RunAsListener
More information on options for the context.xml can be found here
http://www.jboss.org/file-access/default/members/jbossweb/freezone/docs/2.1.0/config/context.html
For the record, Jboss configuration and accompanying documentation is what I call black magic :).. Too many options, too many ways to do the same thing.
HOW TO : Disable annoying message in e-mail by AVG anti-virus
If you are using the free version of AVG Anti-virus by AVG Technologies (Formerly GRISoft), you might have noticed an annoying message that the software inserts in all the e-mails it checks.. The message looks like this
No virus found in this incoming message.
Checked by AVG – http://www.avg.com
Version: 8.0.138 / Virus Database: 270.5.4/1567 – Release Date: 7/22/2008 4:05 PM
I really appreciate the free service that AVG provides for home users, but I don’t want to be reminded or advertise to the world regd the anti-virus I use in every e-mail.
You can disable this message by doing the following in AVG 8.0
- Open the AVG control panel
- Click on Tools -> Advanced Settings in the file menu
- Highlight the “E-mail Scanner” selection in the left hand pane and uncheck the “Certify e-mail” option for both the incoming and outgoing e-mail. Here’s a screen shot.
Week 6 training and improved charts with Google Charts
Week 6 of the Chicago marathon training and I was again not able to keep up with my mid week runs. Although I did manage to improve the charts displaying the training program :).. I added a new column to compare my actual milege to the recommended milege.
Here are the parameters I used
cht=bvg
chs=400×250
chtt=week+6+Training
chdl=Recommended+Miles|Actual+Miles
chco=ff0000,00ff00
chxt=x,y
chxr=1,0,15
chxl=0:|Mon|Tue|Wed|Thu|Fri|Sat|Sun|
chd=t:0,3,4,3,0,7,0|0,2,0,3,0,0,7
chbh=10
Tracking my runs using Google charts : Part II
Comment from my friend Sri, after looking at my post regd using Google Charts API to track weekly runs.
” Hey V, You can show the value of the bars by using the variable CHM”..
Thx for making me lazy dude :).. Here’s the upated image
Tracking my runs using Google charts
I wrote a brief blurb, when Google came out with their Google Charts API. The API essentially allows you to represent your data visually by just generating a URL.. I have been wanting to use this in real life for quite some time now and think I finally found a need :). I am going to be tracking my weekly runs with using this APIÂ moving forward.
Here’s a graphical representation of my runs for Week 5 of my traning for the Chicago marathon
As you can see, I have been slacking off on my mid-week runs.
I used the following parameters to generate the graph
Type = cht (vertical bars)
Legend = chtt (Week 5 training)
Axis Values = chxl (Mon, Tue, Wed, Thur, Fri, Sat, Sun)
The URL I used to generate the image is http://chart.apis.google.com/chart?chtt=Week+5+Training&chts=FF0000,20&chdl=Miles&cht=bvs&chxt=x,y&chxl=0:|Mon|Tue|Wed|Thu|Fri|Sat|Sun|&chs=300×150&chd=t:0,0,3,0,0,0,10&chco=4d89f9,c6d9fd&chbh=20
I still need to figure out, how to show the values in the image and play with the ratio of the axis.
You can get all the information you need about this API by visiting this link http://code.google.com/apis/chart/
HOW TO : Select column in Notepad++
Notepad++, is a great open source editor similar to EditPlus and UltraEdit. One of the features that I really appreciated in EditPlus, was the capability to select a column of data. I checked if NotePad++ has a similar feature and found the following hotkey that can be used to do this..
“Alt + Left Mouse Click” puts you in Column Mode Select
For a complete list of hotkeys that can be used with Notepad++, check out this link
HOW TO : Type "^" on a BlackJack II
This is a quick note for myself… if you ever want to type any special characters or symbols on a BlackJack II, hold the “sym/space” key for a few seconds and the symbox/special character menu will show up..
