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.

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.

Tech2know — Wed, 21 Sep 2011 00:30:30 +0000

Till now I have discussed in detail what is an SAP Archive Information Structure, How it can be created, What is its use and advantages etc. One of the standard SAP Information structure for line items is SAP_FI_DOC_002. We can go to transaction SARI if want to see the data stored in and information structure. But, have you ever thought of where this data is stored at the database level. Well, of course in a database table. No marks for this guess . But which database table. What, if you want to fetch data from an information structure in one of your Z* ABAP report. The name of the information structure cannot be used in a SELECT query.

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.

Tech2know — Thu, 29 Apr 2010 18:35:48 +0000

Friends, it is a reality that secondary storage space is not a major concern now a days. The days are over when we use to pay too much for a ok sort of hard disk in terms of capacity. And because of the high cost, one had to take care of every bit of space.

The era has changed. Now, almost every laptop come with at least 160GB hard disk which is quite enough for our requirement. But, it doesn’t mean that we don’t have to take care of the usage of our hard disk. At times, we may encounter a situation wherein we have to delete unnecessary files,which are taking a lot of space, from the system . For this, first we need to analyse that which are the culprit files that are eating up space. Obviously, we cannot do it manually. So what to do?

Well, there are two tools which can help you analyse the distribution of the space on your hard disk. The names are JDiskReport and FilePro. And believe me guys, these tools serves the purpose very well. The best part is, both the tools are absolutely Free!

You can switch to the table view and toggle the display of files to get more detailed information about a folder.
Size distribution : The size distribution views help you to learn more about the different file sizes that exists on your hard disks. Look at these views to check whether the size distribution is what you expected it to be.
