phpmyadmin access problem and change server from URL

Sun, 30 Sep 2012 01:33:55 +0000

I was having issues with one of the phpmyadmin setups. The first server defined in the config file was not accessible and the theme that I was using was not allowing me to change the server from the first page. This resulted in a state where I was not able to access phpmyadmin in any way. I could not connect to any of the servers. And thus had to hack my way in to phpmyadmin to find out how to connect to other servers from URL. And here is my finding:

convert word document to html

Wed, 27 Jun 2012 01:45:05 +0000

First install the required package:

sudo yum install wv

Description:

Description : Wv is a program that understands the Microsoft Word 6/7/8/9

binary file format and is able to convert Word

documents into HTML, which can then be read with a browser.

And here is the list of the programs that this utility provides:

/usr/bin/wvAbw
/usr/bin/wvCleanLatex
/usr/bin/wvConvert
/usr/bin/wvDVI
/usr/bin/wvDocBook
/usr/bin/wvHtml
/usr/bin/wvLatex
/usr/bin/wvMime
/usr/bin/wvPDF
/usr/bin/wvPS
/usr/bin/wvRTF
/usr/bin/wvSummary
/usr/bin/wvText
/usr/bin/wvVersion
/usr/bin/wvWare
/usr/bin/wvWml

So, if you want to convert a doc file to html just do:

g flag in :s useless in vim

Sat, 05 Nov 2011 07:33:19 +0000

Some time back there was a post on vim_use list about the “/g” flag for the search and replace functionality of the vim. And the response of “Tim Chase” on the same was very elaborate and interesting. I always knew that “/g” is only for replacing multiple occurrences on the same line, but here are few things that I did not know.

   :0/this/s//that

This one will only replace the first occurrence of this in the whole file.

Faster blog with stats removed

Sat, 18 Jun 2011 01:40:01 +0000

I was thinking of removing the statpress plugin for quite some time now, but did not have a good alternative. Today finally I managed to do this as I had few hours to spare. Now that this is done, you should not be getting the database error that some of you on IE were getting and also should have a nicer experience in terms of page load time.

CR Post to Ping.fm not working – resolved.

Thu, 02 Jun 2011 21:42:23 +0000

Last couple of months I was having a tough time getting the plugins in my wordpress to work with the ping.fm service. This is the only service that I rely on to post my blogs. So, basically I was left with no mechanism to publish my new posts 🙁

Now thanks to this post I am able to use the plugin again and thus update my status at multiple places again.

mysql output to an array for easy parsing.

Wed, 11 May 2011 16:51:25 +0000

Today I was looking for some way to put the output of the mysql output in an array in a bash script. Quick google search yeilded to results something like this:

  <td>
    <div class="text codecolorer">
      output=$(mysql -e "select * from table")
    </div>
  </td>
</tr>

The problem with the above approach is that all the words go into separate index. So if you have a line that has space then that is split into multiple index’s. Not good…

using wordpress CLI to post to wordpress

Thu, 24 Mar 2011 15:31:10 +0000

There is a very nice post here: How to post content to a WordPress blog from the command line

I tried this in Fedora 14 and here is the way to get this working in Fedora

  <td>
    <div class="text codecolorer">
      su -<br /> <br /> cpan<br /> <br /> install WordPress::CLI WordPress::Post
    </div>
  </td>
</tr>

Now, once the above completes make sure that the path /usr/local/bin is in you path.

analyze debug queries output for wordpress

Wed, 09 Feb 2011 15:25:14 +0000

Some time back, my website became too slow and I started getting timeout response for quite a lot of my pages. When I analyzed things, I found the issue was with the DB queries taking a lot of time. So, I thought of getting my hands dirty and started with installing the plugin “Debug Queries”. Just in case, you don’t know about the plugin, it lists all the queries to DB along with the time taken for the query when a Admin user visits any page.

Performance issues resolved with my blog.

Fri, 01 Oct 2010 14:53:17 +0000

For last 2-3 weeks there were quite a lot of performance issues with my website. I was looking at the same but could not get enough time to have all of them resolved together. Finally I have spent time on my web hosting and wordpress installation to resolve these issues.

I have taken this opportunity to optimize the blog also. Now the page loading time should be much lesser and you should not be seeing any issues with respect to the site performance or un-availability. If you do see some issues, leave me a comment or contact me through contact me page.

Adding a sub-menu in the wordpress admin menu :)

Thu, 29 Jul 2010 04:15:06 +0000

For the impatient ones, first the code:
(in wp-admin folder, open the file menu.php) and locate the code:

$submenu[’edit.php’][10] = array( _x(’Add New’, ’post’), ’edit_posts’, ’post-new.php’ );

and add the below:

$submenu[’edit.php’][7] = array( _x(’Pending’, ’post’), ’edit_posts’, ’edit.php?post_status=pending&post_type=post’ );

And now the explanation and why do you need this 🙂

Problem:

There is no direct mechanism to access the pending posts in WP admin. I generally post through email and mark them as pending. So, whenever I go to my admin POSTs page, I will look through the list of pending items and post them as and when required. For this, when I am done with changes in one item, I need to either modify the address bar or need to go to posts link and then click the Pending items.

Getting your wordpress self hosted stats on your console with bash script.

Tue, 29 Jun 2010 12:23:05 +0000

Some time back I wrote a blog on how to get your site stats using curl in <a class="zem_slink freebase/en/bash" title="Bash" rel="homepage" href="http://tiswww.case.edu/php/chet/bash/bashtop.html">bash shell. Today we will use the same script to get the stats every few seconds on the terminal on the same line, similar to progress meter.

Here is the script and the description:

wordpress blog stats monitoring from remote using curl and bash and send it in mail.

Fri, 25 Jun 2010 11:47:20 +0000

Here’s something that I had been planning to do for sometime now. I have my blog on wordpress and have Statpress plugin installed. The plugin does give me a good idea of the visits to my site. Now, I have to keep logging in every now and then to check the stats. Also since I did not want to spend some more amount 🙂 so I do not have the shell access to the server, too bad 🙁

find duplicate entry in a list in bash with sed

Fri, 25 Jun 2010 11:46:58 +0000

Here I will take an example of rss2email list, but I guess I will be able to pass on the concept.

Here is example of the output of the r2e list command:

1: http://blog.amit-agarwal.co.in/feed (default: amitag@localhost)
2: http://feeds2.feedburner.com/AllAboutLinux (default: amitag@localhost)
3: http://feeds2.feedburner.com/Command-line-fu (default: amitag@localhost)
4: http://blogs.members.freewebs.com/Members/Blogs/viewBlogRSS.jsp?userid=29731143 (default: amitag@localhost)

Target here is to get the list of all duplicate entries if any. So, first we need to remove the numbers from the begining and the email ID from the end.

How To Build A Self-hosted WordPress Blog For Free

Thu, 04 Feb 2010 15:58:44 +0000

A blog is a layman-friendly variation of a website, and having a blog is one of the many ways to state your presence in the virtual world. While there are many hassle-free blog services out there that will take care of everything except automatically blog for you – like <a href="http://www.makeuseof.com/tags/blogger">Blogger and <a href="http://www.makeuseof.com/tags/wordpress">WordPress, nothing can beat a self-hosted blog in the terms of customization and self pride.

The problem is, the process of building your own self-hosted blog is (almost always) not free and is considered complicated. So most newbies will choose the easier path and never give themselves a chance to experiment.
