Tech2know — Tue, 27 Sep 2011 00:30:02 +0000

Friends, I assume that almost all of us an account on the world’s number 1 social networking website Facebook. Many a times we see an interesting update on Facebook and click on the application and it asks to allow access to the personal information. This is just a trick by the spammers to lure the users and gain access to the personal information. One should make sure not to allow access to such application until or unless you are pretty sure about using the app. Such applications may post updates on your profiles without your knowledge.

If you have already added an application then don’t worry. Its pretty easy to remove application from Facebook account.

You just need to follow below steps to root out the application form your profile.

Login to your Facebook account.
You will see ‘APPS’ section on left hand side of the page.
Take the mouse pointer on the app you want to remove. Click on the ‘pencil’ icon which appears and ‘Remove App’ (as shown below). A confirmation message box will appear. Just click ‘Remove’.

Alternatively you can go to ‘Account Settings’ -> ‘Apps’ and detele them.

That’s it. You just removed an app from Facebook account.

Disable Auto Add Contact Feature in Gmail

Tech2know — Mon, 26 Sep 2011 00:30:46 +0000

For the past some time I was noticing rapid growth in the contact list in my Gmail account. I realized that whenever I send e mail to a new contact it gets added in ‘Other Contacts’ automatically.Actually this is a useful feature which enables auto-complete the contact when you start typing the e mail id in To field.

It is pretty ok if a person sends e mail to limited number of people. Further, many a times you send e mail to persons just once to enquire about some information and don’t want to add them permanently in contacts.

So what to do? Simple! Just follow below steps to disable this feature.

1) Login to your Gmail account.

2) Go to ‘Settings’ –> ‘General’ tab.

3) Select ‘I will add contacts myself’ and ‘Save Changes’.

Its done.

WordPress – Latest/Recent Posts are Not Appearing/Displaying on Home Page

Tech2know — Fri, 23 Sep 2011 09:20:21 +0000

Friends, for the past few days I was pretty annoyed because of a strange problem with my blog. My blog’s home page was not displaying the latest posts. I tried all the methods to correct the problem but all in wain. I activated and deactivated many widgets to see if any of those was the reason. But, nothing worked out. Then I thought to take a look at the source code of the home page and noticed that Cached copy of my home page was generated a month back!

There can be varied reasons for this. One of the solution is mentioned at http://wordpress.org/support/topic/blog-posts-not-showing-up-on-blog-page. This was not the cause in my case.

So, you can go ahead and continue reading if you are also using WP-Super-Cache plugin and facing this problem. This happened not because of any issue in the plugin but because I did not check if the old mod_rewrite rules are still compatible with the latest version of the plugin.

As usual, I kept on updating the plugin to the latest version and overlooked that one of the version set the caching type to ‘Use PHP to serve cache files’ under ‘Advanced’ tab in the plugin’s setting page while my .htaccess file contained the rules which supports mod_rewrite method to serve cache files. I think that the caching type was changed automatically because the rules to support mod_rewrite method were pretty old and was generated by me for an older version of WP Super cache long back.

What can be done? You can either continue using PHP method to serve cache or generate new coding in .htaccess file to support latest version of the plugin.

Method 1: Enable using PHP method to serve cache files.

1) Login to your wordpress blog as admin.

2) Click on ‘WP Super Cache’ under ‘Settings’ on left hand side bar. You will see WP Super Cache Settings page. Check if option ‘Use PHP to serve cache files’ is selected under ‘Advanced’ tab.

3) Click on tab ‘Easy’ –> ‘Update Status’ button. If you see the following message(Notice) then go to step 4.

Below is the message which will be displayed (marked section in above image).

Notice : PHP caching enabled but Supercache mod_rewrite rules detected. Cached files will be served using those rules. If your site is working ok then please ignore this message or you can edit .htacess file in the root of your install and remove SuperCache rules.

4) Go to your .htaccess file and delete the lines starting from # BEGIN WPSuperCache till # END WPSuperCache. You must backup your .htaccess file before making any change.

Method 2 : Enable mod_rewrite method to serve cache files by generating new mod_rewrite rules in .htaccess

1) Go to ‘Advanced’ tab and select ‘use mod_rewrite to serve cache files’.

2) Click on ‘Update Status’ and you will receive a warning message to update mod_rewrite rules in .htaccess file.

3) Go down the page and update the rules by clicking on button ‘Update Mod_Rewrite Rules’.

I opted for mod_rewrite method. This resolved the issue. This is a superb plugin and does the job very well but we need to perform our part as well by checking the latest changes and requirements of the plugin.

CyberGhost – A superb Freeware for Anonymous Surfing

Tech2know — Tue, 20 Sep 2011 00:33:32 +0000

Now a days all of us use the web everyday without knowing that we leave personal information every time we visit a website. You leave behind a load of trails when you surf on the Internet, but not only on your PC. Each access provider knows exactly when you visited which websites. Many websites save your address and the details of what you looked at. Any time anyone visits a web server, they always unwittingly leave behind their IP address as an indication of their visit. It is also specified exactly in the server logs which content was transferred to this IP address, which content was downloaded and where on the website which link was clicked. The website is also often informed as to where you have come from.

There is little privacy on the Internet. Website operators would like to know what you’re interested in. Businesses want to know what you’re up to on the Internet. It’s time for you to protect yourself and your privacy. How ?

CyberGhost VPN is the answer to the question. I just came across this useful piece of software and used its free version.

CyberGhost is an important tool for protecting your privacy. CyberGhost VPN replaces the externally visible IP address, which users have received from their provider when they dial up to connect to the Internet, with a CyberGhost VPN IP address. The CyberGhost user shares this IP address with a number of other users. This procedure ensures that the CyberGhost VPN IP address should not be assigned to one particular CyberGhost VPN user.

Supported operating systems

Windows 7, Vista and XP(32/64 Bit). I installed it on Vista(32 Bit) and it worked fine.

Installation

Installation is pretty straightforward and won’t land you in ‘keep guessing’ mode . After installation you need to create an online account before you can use it. This is only for the first time.

Download

SAP Archiving – Filling or Populating data in Information Structures or SAP AS

Tech2know — Mon, 19 Sep 2011 09:30:10 +0000

There are a number of instances when a person decide to repopulate data in SAP Information structure. This may be decided because the old information structure needs to be deleted and a new equivalent information structure is to be created with a new naming convention. Now the question is, what will happen to the data which is stored in the old information structure. Of course the data will also be deleted if an information structure is deleted. The way out is to populate the newly created one with the data. This can be done very easily by using SAP standard transaction SARI.

Following are the steps :

1) Go to transaction SARI.

2) Click on ‘Status’.

3) Archiving Object: FI_DOCUMNT (For example).

4) Now there are two options namely ‘Status per archive’ and ‘Status per infostructure’. You can use either of these to fill infostructure. As the name indicates, ‘Status per archive’ will show you if the data is completely populated(Status Green) in available information structures per archive session and ‘Status per infostructure’ will display if the data from all archiving sessions is fully populated(Status Green) per infostructure.

5) For filling the data, just select the archive session or infostructure depending on which option you have chosen in step 4 and click on ‘Fill structures’.

Sometimes old archive files are moved to external disks. In this case infostructure will not be filled with the data of those archive files. It will be filled with the data of the archive files which are accessible.

SAP Archiving – Find Tables Included in Archiving Objects

Tech2know — Sun, 18 Sep 2011 08:50:39 +0000

I already discussed in detail about Archiving Objects. For troubleshooting any problem during archiving or for better understanding a person need to know the tables from which data is archived when using a specific archiving object. There are so many tables that it is almost impossible to remember which table gets archived via which archiving object. So, the question is to find out tables associated with an archiving object and the archiving object associated with a table. Yes, you can go to transaction AOBJ for taking a look at the structure definition of a archiving object but it doesn’t show all the tables from which data is archived. For example, if archiving class is used in the archiving object then you need to got to transaction ACLA to view the additional tables from which data gets archived as a part of standard data object.

So, what to do? Well, there is a transaction which make this work pretty easy. The transaction is DB15.

DB15 can be used to display the following :1) The tables from which data will be archived(deleted) if a particular archiving object is used.

2) Which archiving objects can be used to archive the data from a particular table.
