I'm a guy fascinated by ASCII art, since the very early days I saw a piece of this awesome digital art.
As time passed and computers went to be used mostly graphics resolution, ASCII art loose its huge popularity from the early DOS and BBS (internet primordial days).
However, this kind of art is still higly valued by true computer geeks.
In that manner of thoughts, lately I'm researching widely on ASCII art tools and ASCII art open source tools available for Linux.
Last time I check what is available for 'ASCII job' was before 5 years time. Recently I decided to review once again and see if there are new software for doing ascii manipulations on Linux and this is how this article got born.
My attention was caught by aewan (ASCII-art Editor Without A Name), while searching for ASCII keyword description packages with:
apt-cache search ascii
Aewan project official website is on sourceforge check it out here
Here is the complete description of the Debian package:
hipo@noah:~$ apt-cache show aewan|grep -i description -A 5
Description: ASCII-art Editor Without A Name
aewan is an ASCII art editor with support for multiple layers that can be
edited individually, colors, rectangular copy and paste, and intelligent
horizontal and vertical flipping (converts '\' to '/', etc). It produces
both stand-alone art files and an easy-to-parse format for integration
into your terminal applications.
I installed it to give it a try:
noah:~# apt-get --yes install aewan
Selecting previously deselected package aewan.
(Reading database ... 388522 files and directories currently installed.)
Unpacking aewan (from .../aewan_1.0.01-3_amd64.deb) ...
Processing triggers for man-db ...
Setting up aewan (1.0.01-3) ...
aewan package provides three executable binaries:
noah:~# dpkg -L aewan|grep -i /bin/ /usr/bin/aecat
/usr/bin/aewan
/usr/bin/aemakeflic
1. aewan binary is the ascii-art editor itself
2. aecat is utility to display an aewan documents (aewan format saved files)3. aemakeflic – tool to produce an animation from an aewan document
Next I ran it in plain console tty to check how it is like:
hipo@noah:~$ aewan
Below are screenshots to give you an idea how powerful aewan ASCII art editor is:
Aewan immediate entry screen after start up
Aewan ASCII art editor – all of the supported tool functions
As you can see from the shot the editor is very feature rich. I was stunned to find out it even supports layers (in ASCII!!) (w0w!).
It even has a Layers Manager (like GIMP) 
To create my first ASCII art I used the:
New
menu.
This however didn't immediately show the prompt, where I can type the ascii characters to draw my picture. In order to be able to draw inside the editor, its necessary to open at least one layer, through using the menu:
Add Layer (defaults)
then the interactive ASCII art editor appeared.
While an ASCII art is created with the editor you can select the color of the input characters by using Drawing Color menu seen in the above screenshot.
I've played few minutes and created a sample ascii art, just to test the color and editor "look & feel", my conclusions are the editor chars drawing is awesome.
All the commands available via menus are also accessible via a shortcut key combinations:
aewan controls are just great and definitely over-shadows every other text editor I used to draw an ASCII art so far.
Once saved the ASCII art, are by default saved in a plain gzipped ascii text. You can therefore simply zcat the the saves;
Don't expect zcat to show you the ascii as they're displayed in aewan, zcat-ing it will instead display just the stored meta data; the meta data is interpreted and displayed properly only with aecat command.
I've checked online for rpm builds too and such are available, so installing on Fedora, CentOS, SuSE etc. is up to downloading the right distro / hardware architecture rpm package and running:
# rpm -ivh aewan*.rpm
On the official website, there are also instructions to compile from source, Slackware users and users of other distros which doesn't have a package build should compile manually with the usual:
$ tar -zxf aewan-1.0.01.tar.gz
$ cd aewan-1.0.01
$ ./configure
$ make
$ su -c "make install"
For those inrested to make animations with aemakeflic you need to first save a multiple layers of pictures. The idea of creating ASCII art video is pretty much like the old school way to make animation "draw every scene" and movie it. Once all different scene layers of the ASCII art animation are prepared one could use aemakeflic to export all the ASCII layers as common video.
aemakeflic has the ability to export the ASCII animation in a runnable shell script to display the animation. The other way aemakeflic can be used is to produce a picture in kind of text format showing the video whether seen with less cmd.
Making ASCII animation takes a lot of time and effort. Since i'm too lazy and I lack the time I haven't tested this functionality. Anyways I've seen some ascii videos on telnet to remote hosts (some past time); therefore I guess they were made using aewan and later animated with aemakeflic.
I will close this post with a nice colorful ASCII art, made with aewan (picture is taken from the project page):
Talkonaut should also support VoIP (voice conversations), between mobile users, I'm curious if somebody used the program for VoIP and can share feedback?
late and the whole concept was unknown in the Orthodox Christian countries, just until the end of the 19th century.

How to add OpenID functionality to WordPress Comments / What is OpenID?
Tuesday, February 14th, 2012I've recently decided to add Comment as OpenID functionality to my wordpress blog. The reasons to do that is that I myself have today created an OpenID account. Already million of people have OpenID account without even knowing. Most major search engines and social websites like Google, Yahoo, Live Journal, Hyves, Blogger, Flicker, MySpace automatically creates an OpenID account for newly registered users.
It is up to the user to check with each of the aforementioned providers what is the URL of their OpenID account.
Even though OpenID popularity is steadly rising, I'm sure there are still plenty of users who did not heard, used or noticed OpenID yet.
So What the heck is OpenID?
For all those who still haven't heard about it, OpenID is a universal web site login system With just one "unified" OpenID account the user can login to multiple websites with no need to create multiple accounts across each and every different website on the internet.
The only requirement for the user to be able to use OpenID is that the website in question to have (support) for OpenID credential and the user to have existing OpenID account.
Therefore using one single OpenID you can sign in as a certain user to multiple websites on the internet with no need for annoying registration process to each and every new website you encounter. Another benefit OpenID gives to the user is that you don't have to memorize or keep notes of a tens or thousands of different login accounts across the many different websites on the net.
Using OpenID also saves the user from troubles with forgotten password or username as just one OpenID login is used to login you everywhere.
For WordPress blogging platform the Russian Igor Korolev, has written a wordpress plugin – comments-to-wordpress . This plugin adds support for OpenID authentication in WordPress comments.
Here is how to OpenID to WordPress:
1. Download the comments-with-wordpress plugin and unzipAs of writting of this article latest comments-to-wordpress plugin is ver. 1.4.
Download the plugin to blog path directory lets say, /var/www/blog/wp-content/plugins/ and unzip:
# cd /var/www/blog/wp-content/plugins
# wget http://downloads.wordpress.org/plugin/comments-with-openid.zip
...
# unzip comments-with-openid.zip
...
I've also done a mirror for download of comments-with-openid 1.4 here
2. Enable Comments with OpenID wp plugin
Next the plugin has to be Enabled, just like any other wordpress plugin via admin menus:
Plugins -> Inactive -> Comments with OpenID (enable)
Once the plugin is enaabled it is necessery to add some code with a text editor in file /var/www/blog/wp-content/themes/default/comments.php
Small noet to make here: If you're not using the default WordPress theme (like I do), you will have to edit the /themes/your-theme-name/comments.php instead.
Inside the file look for the form input fields:
<p> <input type="text" name="author" ....
...
<p> <input type="text" name="email" id="email" ....
...
<p> <input type="text" name="url" id="url" ....
...
Before the html tags code:
Paste the following code:
<?php comments_with_openid(); ?>
Save the comments.php file and you Identification for new comments with OpenID will appear in your wordpress Comments form.
The OpenID plugin will add a number of service OpenIDs to choose between like you can see in my blog's plugin section or the screenshot below:
The URL https://www.google.com/accounts/o8/id is just a sample and showed because I clicked on the Google icon. If you have a Google profile you can check the exact ID and use it as URL there. Simply if your browser is logged in Gmail and you have Google profile. OpenID should work. As you can see the plugin supports a number of services which already support OpenID auth, the list of services can be easily extended by adding minor changes in …/plugins/comments-with-openid/comments-with-openid.php
There is also another wordpress plugin with the openid name – http://wordpress.org/extend/plugins/openid/
Downloading and enabling the other openid plugin also adds support for OpenID login in your http://your-url.com/wp-admin/ login page.
Installing the OpenID plugin is needed especially if you're a blogger blogging on 5 or 10 different topic oriented blogs, once downloading and installing the OpenID plugin will allow you to login across the blog ring without loosing time or bothering to remember different passwords across all the blogs. Here is a screenshot of the /wp-admin wordpress login page with the OpenID wp plugin enabled:
As of time of writting according to http://openid.net/get-an-openid/what-is-openid/'s website there are over 50000 major websites on the net already accepting OpenID login.
Of course as every technlogy OpenID is not perfect and along with its convenience in some cases it could impose security hole. OpenID opponents claim under some circumstances OpenID is prone to forgery, XSS (cross site scripting) and XSFR attacks. Everyone who is about to use OpenID should be also aware of the great security risk it impose if one OpenID account gets stolen through sniffing, this could mean multiple websites can be accesses with the one single OpenID by the malicious user and a lot of confidential data owned by the user can be revealed or deleted …
With this said I think OpenID is not a recommended login technology for Windows users, as windows is famous for being vulnerable to so many Viruses and Spyware/Malware etc..
With non-free software OSes like MS Windows, the user never cannot for sure if the system is infected, hence using OpenID to transfer credentials over the internet or store an OpenID SSL/(TLS) certificate to identify in websites is TOO DANGEROUS!
Hope this article was helpful. Cya
