How to disable tidy HTML corrector and validator to output error and warning messages

Sunday, March 18th, 2012

I've noticed in /var/log/apache2/error.log on one of the Debian servers I manage a lot of warnings and errors produced by tidy HTML syntax checker and reformatter program.

There were actually quite plenty frequently appearing messages in the the log like:

...

Please fill bug reports and queries using the "tracker" on the Tidy web site.
Additionally, questions can be sent to html-tidy@w3.org
HTML and CSS specifications are available from http://www.w3.org/

line 1 column 1 - Warning: missing <!DOCTYPE> declaration
line 1 column 1 - Warning: plain text isn't allowed in <head> elements
line 1 column 1 - Info: <head> previously mentioned
line 1 column 1 - Warning: inserting implicit <body>
line 1 column 1 - Warning: inserting missing 'title' element
Info: Document content looks like HTML 3.2
4 warnings, 0 errors were found!
...

I did a quick investigation on where from this messages are logged in error.log, and discovered few .php scripts in one of the websites containing the tidy string.
I used Linux find + grep cmds find in all php files the "tidy "string, like so:

server:~# find . -iname '*.php'-exec grep -rli 'tidy' '{}' ;
find . -iname '*.php' -exec grep -rli 'tidy' '{}' ; ./new_design/modules/index.mod.php
./modules/index.mod.php
./modules/index_1.mod.php
./modules/index1.mod.php

Opening the files, with vim to check about how tidy is invoked, revealed tidy calls like:

exec('/usr/bin/tidy -e -ashtml -utf8 '.$tmp_name,$rett);

As you see the PHP programmers who wrote this website, made a bigtidy mess. Instead of using php5's tidy module, they hard coded tidy external command to be invoked via php's exec(); external tidy command invocation.
This is extremely bad practice, since it spawns the command via a pseudo limited apache shell.
I've notified about the issue, but I don't know when, the external tidy calls will be rewritten.

Until the external tidy invocations are rewritten to use the php tidy module, I decided to at least remove the tidy warnings and errors output.

To remove the warning and error messages I've changed:

exec('/usr/bin/tidy -e -ashtml -utf8 '.$tmp_name,$rett);

exec('/usr/bin/tidy --show-warnings no --show-errors no -q -e -ashtml -utf8 '.$tmp_name,$rett);

The extra switches meaning is like so:

q – instructs tidy to produce quiet output
-e – show only errors and warnings
–show warnings no && –show errors no, completely disable warnings and error output

Onwards tidy no longer logs junk messages in error.log Not logging all this useless warnings and errors has positive effect on overall server performance especially, when the scripts, running /usr/bin/tidy are called as frequently as 1000 times per sec. or more

The American Dream Film – How American Economy works

Thursday, March 7th, 2013

money-as-debt-iii-american-dream-and-how-economy-works-american-way

All of us Americans strive for the American Dream,and this film shows you why your dream is getting farther and farther away.

Do you know how your money is created?

Or how banking works?

Why did housing prices skyrocket and then plunge?Do you really know what the Federal Reserve System is and how it affects you every single day?

The movie is pretty much similar in spirit to Money as Debt and to American Debt Explained for Dummies. Just like every movie there is a high element of manipulation in the movie. But anyways the general things explained are sadly very true. The trend of Borrowing to generate new money was embraced by Western European civilization and now is slowly starting to be adopted by Eastern Civilization and Ex-communist countries and newest members of EU like Bulgaria, Romania etc. A whole bunch of nations are pursueing after the "American Dream", non realizing they're destroying there national country and sovereignty and selling their citizens to Private Banking self-issuing structures like America's Federal Reserve. By taking the loans, in case of dying or unabling to pay the loan this loan is transferred to relatives and by taking loans those who do so leave a bad heritage to future generations. Hopefully those watching this little video will take moral and keep their ass away from credits. Enjoy 🙂

How to Add sub-menus to Joomla main navigation buttons (Making dropdown menus) in Joomla

Tuesday, December 7th, 2010

I’m using a template youbizz just recently for a website. The website is already configured to use Joomla as a CMS.
This is a website related to the university so joomla was the perfect choice for a quick and easy to configure Content Management System

The youbizz template really makes difference and make the website layout look & feel quite a business looking.

However I needed a way to make my general configured menu buttons on the website to have a dropdown sub-menus in it

I even didn’t know if Joomla is supporting this, but by a chance I’ve made a submenu to the website Home buttom menu and thus I learned it how I can make submenus.

It actually appears creating the submenus to a menu in Joomla is a piece of cake, all you have to do in joomla administrator is go to to:

Menus -> Main Menu

From there you can configure as website buttons and link them to the ones already prepared in Article Manager

Just in case if you don’t know to add a buttons to a new joomla installation it’s necessary from admin to first go to:

Content -> Article Manager

Next press the New button (a green button with an image of a plus sign)

Thereon put a Title , Alias and in the input box put on everything you want this button pressed to show up in ur website.

Completing that simply press the Apply button and it should be done.
Next step to make the article appear in Menus -> Main Menu is to go this section and respectively from there use the green button with the plus sign to add up a new element to the main menu.

Right after you will have the Menu Item: [ New ] to appear it looks like in the pic below:

Joomla menu add new element screenshot

From the list of items to select you need to select the Article menu element. A submenu will appear in your browser to the Articles reading:

Article Layout
Article Submission Layout
etc.

From this menu you will have to select the Article Layout

The next screen to appear will look like the pic below:

Joomla main menu add new button through article, article layout

Here in article layout few things needs to be adjusted, again you will need to place the Title and the Alias, further after from the Parameters (Basic) located on the right you will have to select an article to link the new menu you’re just creating in Joomla’s new menu.
This is achieved via pressing the Select button located nearby the Select Article
Here it’s important to note the existence of Parent Item scrolldown field. This field will have all the created menu buttons in Main Menu . In case if this is the first one to create in main menu then it could be also empty.

The Parent Item field is really an important field and through it the menu’s submenus are created in Joomla.

For instance let’s say you want the current creating article to be listing as a sub-benu button to another already existing category, instead of listing as a separate button to the Joomla’s main menu navigation.

Well it’s pretty easy just choose from the Parent Item the name of an already existing menu button in Joomla main menu to be the parent of the sub-menu button you want to have.
That’s it now you will have the sub-menu button to appear as a drop down button (if of course your template supports dropdown menus).
There are few more options to choose in between which I found to be quite self explanatory, so I want explain them

But I hope I was able to explain at least the basics how menu subbuttons can be created in Joomla 1.5I find it a bit harder to explain in a bit plain way, but anyways if some of my dear readers is not understanding how to achieve the sub-menus I’m more than willing to help out further via the comments.

Install jwchat web chat jabber interface to work with Debian ejabberd jabber server

Wednesday, January 4th, 2012

JWChat ejabber jabber Ajax / HTML based client logo
 

I have recently blogged how I've installed & configured ejabberd (jabber server) on Debian .
Today I decided to further extend, my previous jabberd installation by installing JWChat a web chat interface frontend to ejabberd (a good substitute for a desktop app like pidgin which allows you to access a jabber server from anywhere)

Anyways for a base of installing JWChat , I used the previously installed debian deb version of ejabberd from the repositories.

I had a lot of troubles until I actually make it work because of some very minor mistakes in following the official described tutorial ejabberd website jwchat install tutorual

The only way I can make jwchat work was by using the install jwchat with ejabberd's HTTP-Bind and file server method

Actually for quite a long time I was not realizing that, there are two ways to install JWChat , so by mistake I was trying to mix up some install instructions from both jwchat HTTP-Bind file server method and JWchat Apache install method

I've seen many people complaining on the page of Install JWChat using Apache method which seemed to be experiencing a lot of strangle troubles just like the mines when I mixed up the jwchat php scripts install using instructions from both install methods. Therefore my guess is people who had troubles in installing using the Apache method and got the blank page issues while accessing http://jabber.servername.com:5280/http-poll/ as well as various XML Parsing Error: no element found errors on – http://ejabberd.oac.com:5280/http-poll/ is most probably caused by the same install instructions trap I was diluted in.

The steps to make JWChat install using the HTTP-Bind and file server method, if followed should be followed absolutely precisely or otherwise THEY WILL NOT WORK!!!

This are the exact steps I followed to make ejabberd work using the HTTP-Bind file server method :

1. Create directory to store the jwchat Ajax / htmls

debian:~# mkdir /var/lib/ejabberd/www
debian:~# chmod +x /var/lib/ejabberd
debian:~# chmod +x /var/lib/ejabberd/www

2. Modify /etc/ejabberd/ejabberd.cfg and include the following configs

While editting the conf find the section:

{listen,
[


Scrolling down you will fine some commented code marked with %% that will read:

{5269, ejabberd_s2s_in, [
{shaper, s2s_shaper},
{max_stanza_size, 131072}
]},

Right after it leave one new line and place the code:

{5280, ejabberd_http, [
{request_handlers, [
{["web"], mod_http_fileserver}
]},

http_bind,
http_poll,
web_admin
]}
]}.

Scrolling a bit down the file, there is a section which says:

%%% =======
%%% MODULES

%%
%% Modules enabled in all ejabberd virtual hosts.
%%

The section below the comments will look like so:

{modules, [ {mod_adhoc, []},
{mod_announce, [{access, announce}]}, % requires mod_adhoc
{mod_caps, []},
{mod_configure,[]}, % requires mod_adhoc
{mod_ctlextra, []},
{mod_disco, []},
%%{mod_echo, [{host, "echo.localhost"}]},
{mod_irc, []},
{mod_last, []},

After the {mod_last, … the following lines should be added:

{mod_http_bind, []},
{mod_http_fileserver, [
{docroot, "/var/lib/ejabberd/www"},
{accesslog, "/var/log/ejabberd/webaccess.log"}
]},

3. Download and extract latest version of jwchat

Of the time of writting the latest version of jwchat is jwchat-1.0 I have mirrored it on pc-freak for convenience:

debian:~# wget https://www.pc-freak.net/files/jwchat-1.0.tar.gz
….

debian:~# cd /var/lib/ejabberd/www
debian:/var/lib/ejabberd/www# tar -xzvf jwchat-1.0.tar.gz
...
debian:/var/lib/ejabberd/www# mv jwchat-1.0 jwchat
debian:/var/lib/ejabberd/www# cd jwchat

4. Choose the language in which you will prefer jwchat web interface to appear

I prefer english as most people would I suppose:

debian:/var/lib/ejabberd/www/jwchat# for a in $(ls *.en); do b=${a%.en}; cp $a $b; done

For other languages change in the small one liner shell script b=${a%.en} (en) to whatever language you will prefer to make primary.After selecting the correct langauge a rm cmd should be issued to get rid of the .js.* and .html.* in other language files which are no longer needed:

debian:/var/lib/ejabberd/www/jwchat# rm *.html.* *.js.*

5. Configure JWChat config.js

Edit /var/lib/ejabberd/www/jwchat/config.js , its necessery to have inside code definitions like:

/* If your Jabber server is jabber.example.org, set this: */
var SITENAME = "jabber.example.org";

/* If HTTP-Bind works correctly, you may want do remove HTTP-Poll here */
var BACKENDS =
[
{
name:"Native Binding",
description:"Ejabberd's native HTTP Binding backend",
httpbase:"/http-bind/",
type:"binding",
servers_allowed:[SITENAME]
}
];

6. Restart EJabberd server to load the new config settings

debian:~# /etc/init.d/ejabberd restart
Restarting jabber server: ejabberd..

7. Test JWChat HTTP-Bind and file server backend

I used elinksand my beloved Epiphany (default gnome browser) which by the way is the browser I use daily to test that the JWChat works fine with the ejabberd.
To test the newly installed HTTP-Bind ejabberd server backend on port 5280 I used URL:

http://jabber.mydomain.com:5280/web/jwchat/I had quite a struggles with 404 not found errors, which I couldn't explain for half an hour. After a thorough examination, I've figured out the reasons for the 404 errors was my stupidity …
The URL http://jabber.mydomain.com:5280/web/jwchat/ was incorrect because I fogrot to move jwchat-1.0 to jwchat e.g. (mv jwchat-1.0 jwchat) earlier explained in that article was a step I missed. Hence to access the web interface of the ejabberd without the 404 error I had to access it via:

http://jabber.mydomain.com:5280/web/jwchat-1.0

JWChat Ejabber webchat Epiphany Linux screenshot

Finally it is handy to add a small index.php redirect to redirect to http://jabber.mydomain.com:5280/web/jwchat-1.0/

The php should like so:


<?
php
header( 'Location: http://jabber.mydomain.com:5280/web/jwchat-1.0' ) ;
?>

Arizona Dream (1993) – Movie Review

Sunday, June 19th, 2011

Just completed Arizona Dream by the famous Serbian director Emil Kosturica. The movie is starring Johny Depp an movie actor I’m not too big fan of.

The movie’s plot is too cracky. It all starts and ends with scenes of some Eskimos, where it progresses and depicts later on an ordinary life of an american fisher.
As movie progresses parts of the life of a successful car sells man comes in place. Axel (Johny Depp) is the main actor. The movie revolves around the sexist element.

Some of the scenes and movie delopment looks quite unexpected. Axel starts living in a place with two beautiful woman (a mother in law and a daguther in law).
The mother in law is famous for her passion to attract and sleep with new young man. Axel fells in love and together they follow a dream of building an airplane which is supposed to be used later on as a mean to kill themselves together and according to Eskimos belief bind together their souls for eternity.
The spiritual concepts of the movie are completely messed up and clearly the movie contains references to multitude of anti-christian ideas.
The movie is generally a bit depressing as the atmosphere one can feel is a jail like. Initially Axel fells in love with the mother in law Ellaine, later on near the movie denouement, he losts his passion for Ellain which is a bit older for his age and fells in love with Grace (which is a way younger and even more attractive).

Grace has a severe problems with feeling of unvalueness and suffers with chronic depression and thus things constantly to kill her self.

Near the end of the movie Axel explains himself in love with Grace (which seems to also be in love with him).
However the ending scenes are too sad as Grace decides finally to kill herself and commits suicide with a gun …

Honestly I expected a way more from the movie and I wouldn’t recommend it as a piece of classics or a movie with some significant value.
The rest of the movies directed by Emil Kosturica seems to be a far more superior and positive than this one.
If you want to save yourself from some insanity just stay away from this cranky movie!
