A quick and easy way to install Social Network on Linux/BSD System with Elgg

Monday, March 14th, 2011

Reading Time: 3minutes

I'm experimenting this days with Elgg – An Open Source Free Software GPLed Social Network which enables users to quickly create Communities.

Elgg is really easy to install and all it requires is a Linux/BSD or Windows system with PHP, MySQL and Apache installed.

Elgg is provided with dozens of nice plugins which for a short time enables individual to create fully operational Social Network like facebook.

Many people nowdays use facebook without realizing how bad facebook is how it breaks their privacy.
Facebook is actually a spy network, it stores data and pictures, likings and user behaviour of million of users around the world.
This needs to be stopped somehow, maybe if people start using the free software networks like elgg to build a mini-community which has profound interests in a certain spheres of work, life and amusement.
The evil empire of facebook will slowly start to loose it's position and the small projects networks based on Elgg and the other Free Software Social Networks which are currently available will start to rise up.
I'm currently really a novice into Elgg but I'm more convinced that the guys who develop it and contribute to it in terms of handy plugins have done really a great job.

It's ultra easy even for non professional middle level user to setup himself an Elgg install.
The installation procedure is not much harder than a simple wordpress blog or joomla based website install.
The installation of elgg takes no more than 10 to 20 minutes, the plugin installation and setup time further could take few days but in the end you have a full featured Social Network! This is really amazing.
The installation of new plugins in elgg is also fool proof / easy all you have to do to equip a newly installed elgg with plugins is to go to it's root directory and look for the mod directory. The new plugins which needs to be installed, could be directly downloaded and saved via links, elinks, lynx or even wget to the elgg installation directory.

Most of the elgg plugins comes in a form of zip files so after being installed simply executing:

server:/home/elgg/mysocialnetwork/mod# unzip

The above cmd will for example unzip the WallToWall elgg plugin and the plugin will be further ready to be enabled via the administrator user set upped during your elgg installation.

The configurations of elgg are being accomplished via:

Administration -> Tool Administration

I should I'm still experimenting with Elgg social, until this very moment I've installed the following elgg plugins:


One very handy feature I truly enjoy about Elgg is that it gives every user an own blog which or in other words when somebody registers in Elgg, he automatically gets a personal blog! How cool this is Yeash 😉
The Elgg photo upload plugin is also another interesting story. The photo plugin is a way better from my first impressions than facebook's buggy upload client.
Elgg also uses heavily jquery for it's various operations and the user experience feels very interactive.

Of course as with all free software things are not perfect some of the elgg plugins or (mods) as they are called are not working.
For example I couldn't make by so far the weather plugin which is supposed to report the weather.

Maybe some tweakening of the not working plugins will easily make them working. What is really important is that the Elgg basis system looks and seems to work really good and enpowers the user with a social network alternatives to the ugly facebook.

In order to experiment with Elgg and I've established a small social network targetting at University College and School Students called MockATeacher –>/i>. The idea behind is to help students in their report writting by providing them with a place where they can meet other students and share files.

Some other aspects I've planned for MockATeacher is to build a small community of people who would like to share about idiot teachers, teacher stupid sayings as well as to mock the idiotic type of education that we and our children are up to in this age.
Just to close up, if you're looking for some time to spend in experimenting in an enjoyable way you definitely need to install elgg and play with it 😉

Frogatto & Friends – One of the TOP 10 Arcade Free Software & Open Source Games for GNU / Linux and FreeBSD

Friday, December 16th, 2011

Reading Time: 4minutes
Frogatto old-school 2d jump and run free software game for GNU / Linux and FreeBSD
1. Frogatto & Friends – Is an Indian Free Software (Open Source) game in the spirit of old-school jump’en runs like Commander Keen, Prehistoric, Jazz Jack Rabbit

The game is really entertaining, the graphics looks approximately nice, the music is awesome, the gamelplay is good even though after some point in the game the moment with “where should I go now, I can’t find exit” comes through and it gets boring.

Generally if you compare with all the existing jump and run arcade games free software games available for Linux and FreeBSD the game will definetely arrange itself in the list of TOP 10 free software Arcade Games
and therefore its my own believe that Frogatto is a game that every GNU / Linux and FreeBSD desktop should have in Application -> Games GNOME menu.

Frogatto is rich of levels, enemies obstacles objects, places to visit (which puts it ahead of many of the linux arcade games which often miss enough game levels, has a too short game plots, or simply miss overall game diversity).

The game’s general look & feel is like a professional game and not just some tiny free software arcade, made by its authors for the sake to learn some programming, graphics or music creation.

Besides that Frogatto & Friends is multi-platform supporting all the major operating systems.
Game supports:

  • Windows
  • Mac
  • iPhone
  • Debian GNU / Linux
  • FreeBSD

The game source code is also available on – The Game’s Official website

The game is available as a deb package in Debian and Ubuntu GNU / Linuxes so to install on those deb based distributions, simply use apt:

debian:~# apt-get install frogatto

The above command will install two packages frogatto (containing the game’s main executable binary) and frogatto-data containinng all the game textures, levels, graphics, music etc.

BTW the package saparation on a gamename and gamename-data in Debian (for all those who have not still noticed), can be seen on most of the games with a game data that takes more disk space.

After the game is installed the only way to start the game is to run it manually through pressing ALT+F2 in GNOME or running the progrtam through gnome-terminal with cmd:

debian:~$ frogatto

Here are few more Frogatto gameplay screenshots:

Frogatto different level screenshot

I’ve noticed Frogatto is also available as an RPM package for Fedora Linux, as well as has a FreeBSD port in the /usr/ports/games/frogatto and this makes it easy to install on most free software OSes in the wild.

While checking , I found an interesting link to a website offering free graphics (pictures), textures and sounds for free and open source games for all those who hold interest into the development of Free Software & Open Source Games make sure you check looks like a great initiative and will definitely be highly beneficial to the development of more and better FSOS Games so I wish them God speed with this noble initiative.

Frogatto is very suitable for growing kids since it doesn’t contain no violence and every now and then the main game actor the Frogatto Frog leads few lines English dialogues with some of the characters found in the quest.
For none speaking English countries, the game can help the kids to learn some basic english words and thus can help develop kids intellect and knowledge
And oh yeah one more criticism towards the game is the Enlish structure, it seems people who wrote the plot can work this out in the time to come. Many of the English sentences during dialogues the frog leads with the cranks he met does not sound like a common and sometimes even correct english / phrases.

Besides those little game “defect”, the game is pretty awesome and worthy to kill some time and relax from a long stressy day.

Free Software Songs and Videos Collection – (Anthem of Free Software) various interpretations

Friday, November 18th, 2011

Reading Time: 2minutes

Richard Stallman picture

I've gathered a collection of 15 Audio and Video songs dedicated to the Free Software / Open Source movement . All of the songs are based on the The Free Software Song Anthem written by Richard Mathew Stallman in the year 1991. The motive of the song is a Traditional Bulgarian song called Sadi Moma Bqla Loza – translated to bulgarian to something like Maid is Planting white Vines
The original Free Software Song symbolizes all free software and the Free Software Movement and GNU and is in the Bulgarian unique / specific folk rhythm of 7 / 8 beats .

Most of the songs which I post hereby could also be found and downloaded from GNU's official Free Software Song page
However some of the songs were only available from Youtube in the non-free format Flash Video (flv) . Hence, since the songs were dedicated to Free Software and apparently were being spread in a non-free format they either was missing any licensing or licensed under GFDL free music / art GNU like license.
To fix up this irragularity and add some freedom in terms of audio format of spreading, I've downloaded them and used ffmpeg2theora to convert the songs to the Free / Open Standard format Ogg Vorbis
I'm quite sure that many people, who use Ubuntu or Linux Mint are pretty much unfamiliar with the Free Software Songs existence, also many people most likely have never heard the Free Software Songs or even those who heard it have rarely heard more than 2 or 3 of the song variations.
Hereby, I'm sure many people who are lovers of Free Software will highly benefit and get inspired to continue in the Free Software by listening to these post shared little Free Software Song Collection .

The covers of the Original version publicly sang by Richard Stallman are in different musical genres, some of the song performances are in Folklore, played on Piano other covers are performed by musical bands in pop / punk en popular music styles, there are one person performances, cheerful christmas like soundings, 8 bit free software song, Metal free software variations etc. In the collection I've included also few other nice songs which are propaganda on free software, even though not a cover of the Free Software Song , I found them myself worthy to be included in the collection..:

Herein you can download or listen all the Free Software Songs version (Enjoyment is guaranteed! 😉 ):

I've also prepared a bundle containing all the 15 Free Software Songs which you can download from here
Enjoy the nice music! Don't forget to share it with everyone you could among with educating the people how important it is to value their freedom in this age of technological human enslavement 😉

Richard Stallman explaining Why IPads and Cell Phones are bad for freedom

Wednesday, July 11th, 2012

Reading Time: 3minutes

It is a public secret that Mobile Phones which does us very good and generally makes our daily lifes way easier are also a big enemy to our natural ihnibited freedom. Life has become such that it is almost inevitable to do any business or do a daily simple jobs without using Mobile Phone. There is almost none practically today that has wilfully rejected to use the mobile phone on any basis, almost anyone except some strangers like Richard Stallman and probably few others security freaks.

I've been shocked to find out the Father of Free Software (Richard Mathew Stallman), well known in the hacker dome as RMS does not own and didn't use any mobiles. The concerns he pointed are very much logical and rightful. Owning a mobile is a great security hole in personal privacy (mobile phones can be easily sniffed by Mobile Operators) as well as anyone wearing a mobile can be tracked up to 5 to 2 meters to the exact location where he is based on the mobile phone cells to which the mobile is connected.

Many people are not aware actually of the severeness of the issue of constant tracking of people everywhere through this call "goodies". Many mobile operators are already running a software which is building place behaviour patterns of every user of their mobile network. In other words, as we're used to bring and use the mobile everywhere in automated program is creating a map for each number assigned in some of the mobile operators. The gathered data about our location going habits can then be easily used as a indicator for predicting our future behaviour, bying habits (how many times we go to super-market), how many times we go to cinema, what kind of interests we hold etc. etc.
This combined with Google, account monitoring could possibly create a system similar to the old movies Big Brother, where all people goods and even attitudes or desires is monitored, influenced and controlled ….

The severeness of the future implications of this constant "personal surveillance and tracking device" as Stallman use to call it is very dangerous for our freedoms.

I tried to live without a mobile phone, just like Stallman for about months, and to tell you the truth the world around seems completely different when you decide not to use 'em. The time I lived wihtout a mobile, clearly show me we have come to the point we cannot any more live without GSM. We fall the trap of dependanding the little "talk box" communication for absolutely everything, obviously sacrificing privacy and freedom for convenience.
Mobiles are just one side of the coin, as the non-free software which is ruling the software market and the use of computers puts another treat and takes away many foundamential freedoms we used to have in the less technological world.

Apple as a vendor of software and hardware also denies and breaks our freedom very badly, as the company tracks everyone who owns anything created by apple connected to the internet. Besides that non-free software producers, could change the user software with a press of a button giving them the opportunity to decide what is good and bad for us, leaving us at a state of a helpless dependable users.

The topic of technological little-by-little enslavement, we're going through nowdays and the denying freedoms, we experience while being convinced by companies that we became more free by each next mambo-jambo gadget or by owning the latest smart-phone is very huge and complex but unfortunately underseen in society. I don't understand why, is it due to the low technical skills of mass users is it due to a "not-care what will happen in future" attitude, but obviously people openly discussing or protesting the technologization taking away our freedom is almost zero ….

Here is the video I found in youtube in which Stallman is asked few, questions on Ipads (IBADS) and Mobile Phone use. I believe his short explanation synthesizes the problem quite well ;;;;

I just wonder after you check the video, Would you still accept an Ipad as a birthday gift ? 🙂
Do you still think cell-phones are "good" freedom safe and reliable ?

The lack of sharing in modern world – One more reason why sharing Movies and any data on the Internet should be always Legal

Saturday, July 7th, 2012

Reading Time: 2minutes

Importance of sharing in modern digital society, sharing should be legal, Sharing caring
 I've been thinking for a lot of time analyzing my already years ongoing passion for Free Software, trying to answer the question "What really made me be a keen user and follower of the ideology of the free software movement"?
I came to the conclusion it is the sharing part of free software that really made me a free software enthusiast. Let me explain ….

In our modern world sharing of personal goods (physical goods, love for fellows, money, resources etc.) has become critically low.The reason is probably the severely individualistic Western World modern culture model which seems to give good economic results.
Though western society might be successful in economic sense in man plan it is a big failure.
The high standard in social culture, the heavy social programming, high level of individualism and the collapsing spirituality in majority of people is probably the major key factors which influenced the modern society to turn into such a non-sharing culture that is almost ruling the whole world nations today.

If we go back a bit in time, one can easily see the idea and general philosophy of sharing is very ancient in nature. It was sharing that for years helped whole societies and culture grow and mature. Sharing is a fundamental part of Christian faith and many other religions as well and has been a people gathering point  for centuries.
However as modern man is more and more turning to the false fables of the materialistic origin of  man (Darwininsm), sharing is started seeing as unnecessary . Perhaps the decreased desire in people to share is also the reason why in large number people started being  self-interest oriented as most of us are nowadays.

As we share less and less of our physical and spiritual goods, our souls start being more and more empty day after day. Many people, especially in the western best developed societies; the masses attitude towards sharing is most evidently hostile.
Another factor which probably decreased our natural human desire to share is technocracy and changing of communication from physical as it used to be until few dacades to digital today.

The huge shift of communication from physical to digital, changes the whole essence of basic life, hence I believe at least the distorted sharing should be encouraged on the Internet (file movies and programs sharing) should be considered normal and not illegal..
I believe Using Free Software instead of non-free (proprietary) one is another thing through which we can stimulate sharing. If we as society appreciate our freedom at all  and  care for our children future, it is my firm conviction, we should do best to keep sharing as much as we can in both physical and digital sense.

BB – A must see ASCII Art Audio / Video portable demo for Linux, FreeBSD, UNIX and DOS

Thursday, May 24th, 2012

Reading Time: 5minutes

bb Audio Visual ASCII art Linux FreeBSD demonstration old school demo logo

I know and I have enjoyed BB – Portable Demo for already a decade.
I'm sure many newbies to the Free And Open Source (FOSS) realm don't know or heard of bb's existence as nowdays ASCII art is not so well known among youngsters. Hence this short post aims to raise some awareness of the existence of this already OLD but GOLD – awesome! text console / terminal demonstation BB 🙂

bb is pretty much in the spirit of Oldschool Assembly DOS demo scene dominating the geeks dome in the late 80's and yearly 90's.

Historically bb used to be one of the main stunning things one could show to a fellow GNU / Linux new comer.

For the year 2000, seeing all this awesome ASCII video demo running on free Operating System like GNU / Linux was a big think.
The fact that such an advanced ASCII art was distributed freely for an OS which used to exist since only (6 / 7 years) was really outstanding of its time.

BB text ascii art Linux demo entry screen characters matrix

I still remember how much I was amazed seeing a plain ascii video stream was possible only Linux. Moreover the minimal requirements of bb were quite low for its time – it worked on mostly all PCs one can find at the time.

BB's minimum requirements to work with no chops is just an old 486/66 DX2 CPU Mhz with few megas of memory (32MB of memory was more than enough to run it)

BB text sacii art Linux demo entry screen char matrix

A very unique feature of bb was it was the first Linux demo that succesfully run simultaneously playing on two monitor screens as one can read on the project website.
Unfortunately I didn't owned two monitors back in the day so never ever had the opportunity to see it running on two screens.
Anyhow I've seen it runnign somewhere on some of the Linux install fests visited some years ago…

The demo was developed by 4 man group ppl – the AA group the same digital artists are also the guys behind the AA Project.

AA Lib mascot logo :)

The main aim of AA-lib was to make possible (Doom, Second Reality, X windows) to run rendered in plain ASCII art text.

The project succeeded in a lot of his goals already as there is already existent such an ascii art ports of large games like QUAKE! Be sure to check this awesome project too AAquake ascii quake page is here
, as well as video and pictures could be viewed under a plain console Linux tty or in terminal (via SSH 🙂 )

Thanks to AA-Lib even text mode doom exists.

bb as well as aa-lib has ports for most modern Linux distros in that number one can easily get rpm or deb packages for most of distros.
On Slackware Linux you should compile it from source. Though compilation should be a straightfoward process, not that i tried it myself but I remember a close friend of mine (a great Slackware devotee) who was the one to show me the demo for a first time on his Slackware box.

1. Installing bb on Debian Linux

Debian Linux users like me are privileged as for already many years a Debian package of bb is maintaned thanks to Uwe Herman

Hence for anyone willing to enjoy bb install it by running:

debian:~# apt-get --yes install bb
ho@debian:~$ bb

If you're running a X server the aa-lib will immediately run with its X server compiled support:

Running BB Music Screesnhot

2. Installing BB demo on FreeBSD

On FreeBSD, bb demo has a port to install it run:

freebsd# cd /usr/ports/misc/bb freebsd# make install clean ...

Here is good time to say that even though in most of the machines, I've tested the demo I had on some of the hosts problems with sound due to buggy sound drivers.
As of time of writting hopefully on most machines there will be no troubles as most of the Linux sb drivers are better supported by ALSA.

Everyone interested in both Free Software and ASCII art knows well how big in significance is the AA-lib project for the historical development and attraction for new hackers to the Linux dome.
In that sense AAlib head developer Jan HubickaBy the way Jan Hubicka is also the author of another Linux tool called xaos. Xaos is a tool to deal with some kind of advanced higher mathematics stuff called fractals.

XAOS Screenshot Debian Squeeze Linux

Unfortunately I don't know a bit for fractal maths and what the purpose of the tool is but as you can see on the shot it looks nice running 🙂

Here are also, lot of the major BB parts in shots:

Why I never liked Mandrake Linux / Mankdrake Linux has took its name from an 1930s comics Mandrake the Magician

Wednesday, May 9th, 2012

Reading Time: 2minutes

I never liked Mandrake Linux, since day 1 I saw it.
Historically Mandrake Linux was one of the best Linux distributions available for free download in the "Linux scene" some 10 to 12 years ago.

Mandrake was simple gui oriented and trendy. It also one the Linux distribution with the most simplified installer program and generally a lot of GUI software for easy configuration and use by the end user.

Though it's outside nice look, still for me it was like an "intuition" that Mandrake is not so good as it appeared.

Now many years later I found by chance that Mandrake has been sued to change their Operating System name with another, due to a law suit requit by the copyright holders of Mandrake The Magician comics. "Mandrake the Magician" used to be a very popular before the Second World war in the 1930's.

Mandrake the Magician Comics Magazine from 1930's Cover, Mandrake the Black Magic Magician

It obviously not a co-incidence that the Mandrake names was after this comics and not the mandrake herb plants available in Europe, Africa and Asia. This is clear in Mandrake Linux distro earlier mascot, you see below:

Mandrake Linux old distribution logo, magician penguin

Later on they changed Mandrake's logo to loose the connection with Mandrake The Magician and used another new crafted logo:

Mandrake GNU Linux newer logo
Its quite stunning nowdays magician obsession, has so heavily infiltrated our lives that even something like a Free Softwre Linux distribution might have some kind of reference to magician and occult stuff (I saw this from the position of being Christian) …

Later due to the name copyright infringement Mandrake Linux was renamed first to Mandragora Linux.
Instead of putting some nice name non related to occultism or magic stuff the French commercian company behind Mandrake rename it to another non-Christian name Mandragora.
Interestingly the newer name Mandragora as one can read in wikipedia means:

Mandragora (demon), in occultism

Well apparently, someone from the head developers of this Linux distribution has a severe obsession with magic and occultism.

Later MandrakeSoft (The French Company behind Mandrake Linux) renamed finally the distribution to Mandriva under the influence of the merger of Mandrake with the Brazillian company Connectiva this put also an over to the legal dispute copyright infringement dispute with Hearst Corporation (owning the rights of Mandrake the Magician).

Having in mind all fact on current Mandriva "dark names history", I think it is better we Christians avoid it …

Editting binary files in console and GUI on FreeBSD and Linux

Thursday, April 26th, 2012

Reading Time: 7minutesI’ve recently wanted to edit one binary file because there was compiled in the binary a text string with a word I didn’t liked and therefore I wanted to delete. I know I can dig in the source of the proggie with grep and directly substitute my “unwatned text” there but I wanted to experiment, and see what kind of hex binary text editors are for Free OSes.
All those who lived the DOS OS computer era should certainly remember the DOS hex editors was very enjoyable. It was not rare case, where in this good old days, one could simply use the hex editor to “hack” the game and add extra player lives or modify some vital game parameter like put himself first in the top scores list. I even remember some DOS programs and games was possible to be cracked with a text editor … Well it was times, now back to current situation as a Free Software user for the last 12 years it was interesting to see what is the DOS hexeditor like alternatives for FreeBSD and Linux and hence in this article I will present my findings:

A quick search in FreeBSD ports tree and Debian installable packages list, I’ve found a number of programs allowing one to edit in console and GUI binary files.

Here is a list of the hex editors I will in short review in this article:

  • hexedit
  • dhex
  • chexedit
  • hte
  • hexer
  • hexcurse
  • ghex
  • shed
  • okteta
  • bless
  • lfhex

1. hexedit on Linux and BSD – basic hex editor

I’ve used hexedit already on Linux so I’ve used it some long time ago.

My previou experience in using hexedit is not too pinky, I found it difficult to use on Redhat and Debian Linux back in the day. hexedit is definitely not a choice of people who are not “initiated” with hex editting.
Anyways if you want to give it a try you can install it on FreeBSD with:

freebsd# cd /usr/ports/editors/hexedit
freebsd# make install clean

On Debian the hexedit, install package is named the same so installation is with apt:

debian:~# apt-get –yes install hexedit

hexedit screenshot Debian Linux Squeeze

2. Hex editting with chexedit

I’ve installed chexedit the usual way from ports:

freebsd# cd /usr/ports/editors/chexedit
freebsd# make install clean

chexedit is using the ncurses text console library, so the interface is very similar to midnight commander (mc) as you see from below’s screenshot:

Chexeditor FreeBSD 7.2 OS Screenshot

Editting the binary compiled in string was an easy task with chexedit as most of the commands are clearly visible, anyways changing a certain text string contained within the binary file with some other is not easy with chexedit as you need to know the corresponding binary binary value representing each text string character.
I’m not a low level programmer, so I don’t know the binary values of each keyboard character and hence my competence came to the point where I can substitute the text string I wanted with some unreadable characters by simply filling all my text string with AA AA AA AA values…

chexedit on Debian is packaged under a deb ncurses-hexedit. Hence to install it on Deb run:

debian:~# apt-get –yes install ncurses-hexedit

Further on the binary to run chexedit on binary contained within ncurses-hexedit is:

debian:~# hexeeditor

3. Hex Editting on BSD and Linux with hte

Just after trying out chexedit, I’ve found about the existence of one even more sophisticated hexeditor console program available across both FreeBSD and Linux.
The program is called hte (sounds to me a bit like the Indian word for Elephant “Hatti” :))

hte is installable on Debian with cmd:

debian:~# apt-get install ht

On FreeBSD the port name is identical, so to install it I execed:

freebsd# cd /usr/ports/editors/hte
freebsd# make install clean

hte is started on Debian Linux (and presumably other Linux distros) with:

$ hte

On FreeBSD you need to run it with ht command:

freebsd# ht

You see how hte looks like in below screenshot:

ht has the look & feel like midnight commander and I found it easier to use than chexedit and hexeditor
4. hexer VI like interface for Linux

As I was looking through the available packages ready to install, I’ve tried hexer

debian:~# apt-get install –yes hexer

hexer does follow the same standard commands like VIM, e.g. i for insert, a for append etc.

Hexer Debian Linux vim like binary editor screenshot

It was interesting to find out hexer was written by a Bulgarian fellow Petar Penchev 🙂
(Proud to be Bulgarian) – Petar Penchev has his own page on

As a vim user I really liked the idea, the only thing I didn’t liked is there is no easy way to just substitute a string within the binary with another string.

5. hexcurse another ncurses library based hex editor

On Deb install and run via:

debian:~# apt-get –yes install hexcurse
debian:~# hexcurse /usr/bin/mc

Hexcurse Debian Linux text binary editor screenshot

hexcurse is also available on FreeBSD to install it use cmd:

freebsd# cd /usr/ports/editors/hexcurse
freebsd# make install clean

To access the editor functions press CTRL+the first letter of the word in the bottom menu, CTRL+H, CTRL+S etc.
Something I disliked about it is the program search is always in hex, so I cannot look for a text string within the binaries with it.

6. ghex – Editting binary files in graphical environment

If you’re running a graphical environment, take a look at ghex. ghex is a gnome (graphical hex) editor.Installing ghex on Debian is with:

debian:~# apt-get –yes install ghex

To run ghex from terminal type:

debian:~# ghex2

GHex2 GNOME hex binary editor screenshot

To install ghex on FreeBSD (and I assume other BSDs), install via port:

freebsd# cd /usr/ports/editors/ghex
freebsd# make install clean

Gnome hex editor have plenty of tools, useful for developers to debug binary files.

Some nice tools one can find are under the the menus:

Windows -> Character Table

This will show a complete list of each keyboard sent character in ASCII, Hex, Decimal, Octal and Binary

Screenshot ghex Character table Debian Linux

Another useful embedded tool in ghex is:

Windows -> Type Convertion Dialog

Ghex type convertion dialog screenshot

Note that if you want to use the Type Convertion Dialog tool to find the representing binary values of a text string you will have to type in the letters one by one and save the output within a text file and later you can go and use the same editor to edit the text string within the binary file you like.

I’m not a programmer but surely for programmers or people who want to learn some binary counting, this 2 ghex edmebbed tools are surely valuable.

To conclude even though there are plenty of softwares for hex editting in Linux and BSD, none of them is not so easy to use as the old DOS hexdedit tool, maybe it will be a nice idea if someone actually rewrites the DOS tool and they package it for various free operating systems, I’m sure many people will find it helpful to have a 1:1 equivalent to the DOS tool.

7. Shed pico like interfaced hex editor

For people, who use pico / nano as a default text editor in Linux shed will probably be the editor of choice as it follows the command shortcuts of picoOn Deb based distros to install it run:

debian:~# apt-get install –yes shed

shed pico like hex binary editor Linux

Shed has no BSD port as of time of writting.8. Okteta a KDE GUI hex editor

For KDE users, I found a program called okteta. It is available for Deb based Linuxes as deb to install it:

debian:~# apt-get –yes install okteta

Screenshot Okteta Debian GNU / Linux Squeeze

As of time of writting this article there is no okteta port for BSDs.
Okteta has plenty of functions and even has more of a functions than ghexedit. Something distinctive for it is it supports opening multiple files in tabs.

9. lfhex a large file text editor

lfhex is said to be a large (binary) file text editor, I have not tested it myself but just run it to see how it looks like. I don’t have a need to edit large binary files too, but I guess there are people with such requirements too 🙂

lfhex - Linux The Large file hex editor

To install lfhex on Debian:

debian:~# apt-get install –yes lfhex

lfhex has also a FreeBSD port installable via:

freebsd# cd /usr/ports/editors/lfhex
freebsd# make install clean

10. Bless a GUI tool for editting large hex (binary) files

Here is the description directly taken from the BSD port /usr/ports/editors/bless

Bless is a binary (hex) editor, a program that enables you to edit files asa sequence of bytes. It is written in C# and uses the Gtk# bindings for theGTK+ toolkit.

To install and use ot on deb based Linuxes:

debian:~# apt-get install –yes bless

On BSD installation is again from port:

freebsd# cd /usr/ports/editors/bless
freebsd# make install clean

Something that makes bless, maybe more desirable choice for GUI users than ghex is its availability of tabs. Opening multiple binaries in tabs will be useful only to few heavy debuggers.

11. Ghextris – an ultra hard hacker tetris game 🙂

For absolute, hacker / (geeks), there is a tetris game called ghextris. The game is the hardest tetris game I ever played in my life. It requires more than regular IQ and a lot of practice if you want to become really good in this game.

To enjoy it:

debian:~# apt-get –yes install ghextris

Unfortunately there is no native port of ghextris for BSD (yet). Anyhow, it can be probably run using the Linux emulation or even compiled from source.
Well that’s all I found for hexedit-ing, I’ll be happy to hear if someone can give me some feedback on his favourite editor.

The day wasn’t so bad at all

Yesterday I was on a birthday of a one girl Krisi she is 18 already. It was a standard teen party. Awful place, I drunk 3 beers and smoked a lot of cigaretes in general we discussed with some ppl Does the Lord exist things. Is evolution real is it possible at all things like this. There was one boy who was keen on Free Software GPL etc. I realized I’m a real psycho after I started to convince him Windows and M$ products are much better than free software :]. After 3 hours speaking like a 15 years m$ user. When walking back for home. I asked my self what the heck? What I did I’m real psycho ;]. Zuio and I broke 1 flowerpot when doing POGO on a Hipodil song. I eat some strange salad with hands ( I pretended to be a Bangla person ) :]. Nomen drunk a lot and got angry at a guy and proposed to start a fight:]. In 5:30 a.m. we were already at home. Our mood got fucked up a little when going back to home. In the morning Papi wake me up and suggested to go to a coffee, I aggreed as usual but I did misunderstood about the place where we decided to see, and waited on other place after that I realized I did a mistake and he meant we have to see each other in the Winter Theather not the Summer One (silly me). After that normal day I eat. I did some server descriptions, played mame in Nomen (I went his home). I was able to start gxmame to work in fullscreen in the end (my integrated video card is doing alot of problems about the games) but I found out the xmame -ef 1 option. That one rules.END—–

Just great our Bulgarian government spend money on buying proprietary software OS to run a Free Software based solution.

This example is pretty examplary of what our country looks like. Sad …
