Already on a couple of mail boxes located on one of the qmail powered mail servers I adminiter, there is an over QUOTA reached problem encountered.
Filling up the mailbox quota is not nice as mails starts get bounced back to the sender with a message QUOTA FULL or EXCEEDED MESSAGE, if this is a crucial mail waiting for some important data etc. the data is never received. Below is a copy of the mail quota waarning notification message:

Your mailbox on the server is now more than 90% full. So that you can continue
to receive mail you need to remove some messages from your mailbox.
As you can read from the copy of the mail message above, the message content sent to the mail owner whose quota is getting full is red from /var/vpopmail/domains/.quotawarn.msg
The mail reaching quota problem is very likely to appear in cases like low mailbox quota set, but sometimes also occurs due to bugs in vpopmail quota handling.
Various interesting configuration settings for mail quotas etc. are in /home/vpopmail/etc/vlimits.default file, (assuming vpopmail is installed in /home).
In my specific case, the default vpopmail mailbox quota size was set to only 40 Megabytes. 40MB is too low if compared to todays mailbox size standards which in Gmail and Yahoo mail services are already a couple of gigabytes. Hence to get around the quota troubles, I removed the quota for the mail. To remove the quota size in vpopmail set for address (email_user@my-mail-domain.net) used cmd:
To save myself from future quota issues, I decided to apply a permanent fix to all those over quota size VPOPMAIL mailbox problems by removing completely quota restriction for all mailboxes in my vpopmail existent mail domain.
To do so, I wrote a quick simple bash loop one-liner script:
qmail-server:~# cd /home/vpopmail/domains
qmail-server:~/vpopmail/domains# cd my-mail-domain.net
qmail-server:~/vpopmail/domains/my-mail-domain.net# for i in *; do \
vmoduser -q NOQUOTA $(echo $i|grep -v vpasswd)@my-mail-domain.net; \
done
This works only on vpopmail installations which are configured to store the mail messages directly on the filesystem. Therefore this approach will not work for people who during vpopmail install had configured it to store mailboxes in MySQL or in other kind of SQL db engine.
Anyways for Vpopmail installed to use SQL backend, the script can be changed to read directly a list with all the mailboxes obtained from databasae (SQL query) and then, loop over each of the mail addresses apply the vmoduser -q NOQUOTA mail@samplemaildomain.net.
I've written also a few lines shell script (remove_vpopmail_emails_domain_quota.sh), it accepts one argument which is a vpopmail domain to which the admin would like to reset all applied mailbox quotas. The script is useful, if you have to often remove all quotas for vpopmail domainsor have to do quota wipe out simultaneously for multiple email domain names located on different servers.
I've hit an interesting article in Wikipedia called Comparison of BSD operating systems The article explains basic difference between different BSD (Berkley Software Distributions) and what is the primary accent of each of the BSD (free software OS) distributions. It also reveals basic details about the history and how each of the BSD's came to existence. I recommend to anyone interested in free software as it is just a great reading for everybody interested in FOSS.
The most interesting part of the wiki thread is a bar chart, provided by BSD Certification Group research conducted in September 2005.
The above diagram is showing the proportion of users of each BSD variant from the BSD usage survey prior conducted
The research is already 6 years old, and unfortunately as of time of writting seems to be the only publicly available. Though being outdated, I believe generally the bar charts distributions along different BSD variants would be mostly true. The only big difference will be probably in PC-BSD which is not even on the diagram should have outbeaten DragonflyBSD's use. Since there is no public data available for 2012 and the years 2005 – 2012 for the use percantage of each of the BSD distributions, I've thought about a pseudo way to get some general statistics on each of the BSD distributions popularity. The methodology to gather the required statistics comes to simply, type in Google each of the BSD variant "code names" (e.g. freebsd, netbsd, openbsd etc.) and look at the number of results returned. It seems logical the more results distribution keyword searched returns, the bigger the probability of more users to be involved in developing or using the respective BSD variant.
Below you see the results, I've gathered in my quick "google research":
As you can see in the above dataFreeBSD is still probably leading the BSD use, the public interest to OpenBSD – BSD focused on security has significantly grow since the last 6 years. Next it is seen the PC-BSD users base has probably tremendously increased and according to the Google results returned it is probably on a 3rd place by users interest (use?) followed by NetBSD with only 1.47% of all the BSD users. Lastly with only 0.99%, orders Dragonfly BSD which no longer is so popular as a Desktop BSD based OS as it used to be back in 2005. Again the presented diagram results are based on only on the factor of Google BSD variant popularity and hence shouldn't be consired too trustworthy, still I'm sure it gives a general idea on how used is each of the BSD variants as of Jan 2012.
Free Software (FS) is free as in freedom as well as free as in price. Free and Open Source Software (FOSS) is developed by geek hobbyist which voluntarily put their time and effort in writting, testing and sharing with anyone for free million of lines of programming code. This doesn't mean however the price of free software costs is 0 (zero). Though the "end product" – Free Software developed is FREE, "real" software costs as with any other product costs huge money.
Here is how JEB got the $19 billions, a quote taken from his blog:
"By using David A Wheeler’s sloccount tool and average wage of a developer of US$72,533 (using median estimates from Salary.com and PayScale.com for 2011) I summed the individual results to find a total of 419,776,604 source lines of code for the ‘pristine’ upstream sources, in 31 programming languages — including 429 lines of Cobol and 1933 lines of Modula3!
In my analysis the projected cost of producing Debian Wheezy in February 2012 is US$19,070,177,727 (AU$17.7B, EUR€14.4B, GBP£12.11B), making each package’s upstream source code worth an average of US$1,112,547.56 (AU$837K) to produce. Impressively, this is all free (of cost).
James has done incredible job with this great research and he deserves applause. However I believe the numbers proposed by his research are slightly different if we speak about realistic cost of Debian GNU / Linux. The real costs of the working software ready to install on a user PC are way higher, as according to Jeb's research only the software cost based on code line count is considered.
Hence James software estimation calculates only the programming costs and miss many, many factors that constitute the software end cost. Some of the many, many REAL COST / expenses for developing a huge Free Software project like Debian GNU / Linux to be considered are:
a) bandwidth costs for hosting free software (on the server side)b) bandwidth cost for developers or FS users downloading the software
a) Time spend to spread the word of the great added value of Debian and bundled software (Mouth by Mouth Marketing)
b) Time spend to advertise Debian and its free software components on blogs, social networks (identi.ca, facebook, twitter) etc.(Voluntary online Marketing, SEO etc.)
c) Time spend on generating ideas on future program versions and reporting them to Debian FS community
d) Time on evaluation and feedback on software
e) Time spend on managing free software repository (download) servers voluntarily (by system administrators)
f) Time spend by users on Bug Tracking & Bug Reporting
g) Time spend on research and self-actualization by software developer)
h) Time spend on software Quality Assurance
This are most of the multiple factors which should probably influence the cost of any non-free (proprietary software) project. No matter this costs apply for non-free software, it perfectly applies for free software as well.With all said if if we assume the non-programming costs are equal to the programming costs of $ 19 000 000 000 (suggested by Jeb). This means the real cost of Debian will presumably be at least $32 000 000 000. Putting $ 19 billion for all this long list of "additional" costs (besides pure source) factors is probably still very under-scored number.
the developers use of their own computers (hardware depreciation)
electricity bill of the volunteer (developer) working on the program or project
electricity bills for servers where free software is stored and available for download
volunteer developer IT skills and tech knowledge (KNOW HOW)
Internet, network, dial up bandwidth cost
personal time put in FS development (programming, design, creativity etc.)! here the sub costs are long:
Costs for Project Management Leaders / Project Coordination
The complexity of each of the projects constituting Debian
Very interesting figure from Jeb's research is the Programming Languages break down by source code figure. Jamesresearch reveals on the 4 major programming languages used in the 17000+ software projects (part of Debian GNU / Linux):
ANSI C with 168,536,758 – (40% of all projects source code)
C++ at 83,187,329 – (20% of all projects source)
Java 34,698,990 – (lines of code 8% of sources)
Lisp – (7% of all projects source code)
His research also provides a general idea on how much the source code of some of the major FOSS projects costs. Here is a copy of his figures

As you can imagine all the source evaluation results, are highly biased and are open for discussion, since evaluating a free software project/s is a hard not to say impossible task. The "open" model of development makes a project very hard to track, open source model implies too many unexpected variables missing from the equation for clear calculation on costs. What is sure however if turned in money it is very expensive to produce. At present moment Debian Project is sponsored only through donations. The usual yearly budget 5 years ago for Debian was only $80 000 dollars a year!! You can check Debian Project annual reports throughout the years here , for year 2012 Debian Project budget is as low as $ 222, 677 (US Dollars)! The output price of the software the project provides is enormous high if compared to the low project expenses!
For us the free software users, price is not a concern, Debian is absolutely free both as in freedom and free as in beer 😉
Linus's name is encountered once in the Scriptures (The Holy Bible) in the second book part of the New Testament scriptures:
I really like King James English version of the bible, here is the text extracted from there, mentioning Linus's name:
2 Timothy 4:21 Doe thy diligence to come before winter. Eubulus greeteth thee,
and Pudens, and Linus, and Claudia, and all the brethren. (From KJV 1611 Translation)
Here is a modernized version of the same verse taken from the New American Standard Bible Version (1995):
2 Timothy 4:21 Make every effort to come before winter. Eubulus greets you,
also Pudens and Linus and Claudia and all the brethren.
- New American Standard Version (1995)
Other curious fact maybe, even uknown to Linus Torvalds himself is Saint Linus used to be the first bishop of Rome, after the Apostles bishopship. This makes Saint Linus the second in place Roman Catholic Pope after Saint Peter in early Western Church. There are some early sources which says Pope Clement I was the second pope of Rome, however probably this sources are erroneous, since some very important early written sources like the Apostolic Constitutions states Linus was the first bishop of Rome and was ordained by St. Paul. The same documents says Pope Linus was succeeded by Pope Clement – ordained by saint Peter.
Below's paste is taken directly from BibleGateway.com cofirming about Pope Linus being the sacond Roman Catholic Pope:
Linus (a net), a Christian at Rome, known to St. Paul and to
Timothy, (2 Timothy 4:21) who was the first bishop of Rome after the apostles. (A.D. 64.)
Something Pope Linus is known with is, to have issued a church decree that woman should cover their heads in church.This ancient church tradition is still observed more or less in the Orthodox Church. It is not known much about how Saint Pope ruled the early Western Church but since the western and eastern Church used to be in communion in these early days, this means the nowdays Roman Catholic saint Linus is probably a saint in the Eastern Orthodox Church as well. According to some unprovable written sources Pope Linus later suffered martyrdom and was buried in Vatican Hill next to saint apostle Peter.
St. Linus according to Church tradition passed away in the 1st securury A.D. Below's paste is taken directly from BibleGateway.com a multilingual website location for reading the bible
Linus
(a net), a Christian at Rome, known to St. Paul and to
Timothy, (2 Timothy 4:21) who was the first bishop of Rome after the apostles. (A.D. 64.)
I've merged a picture of how saint Linus used to look with one of the pictures of Linus Torvalds. It's rather funny they actually look alike 😉 🙂 🙂
The creator of GNU/Linux kernel Linus Torvalds might not be a saint in Christian sense, but his deed is definitely saintly as he initiated the creation of the Linux kernel and decided to share its source and publish it under GPL (General Public License). The phenomenon of GNU / Linux Free Operating System existent today and specific type of development is definitely a miracle. The general philosophy of sharing with neighbor your software is also very close to the Christian philosophy of sharing. Actually too many of the ideas of the free software and "open source" movements resemble purely Christian ideas.
The software sharing philosophy has become a reality thanks to Richard Stallman and his GNU Project, however the existence of GNU / Linux as a complete operating system become reality thanks to the Linus torvalds kernel efforts which is known under the code name Linux. Talking about names, maybe not much will know, that Linux kernel used to have a different name in the early stage of its development, its first code name was FreaX
Some of the computer DOS geeks certainly should remember Terminal Velocity / (Terminal Reality Inc. – TRI) DOS 3D Realms (ex Apogee company) game. For those who are younger or for any reason miss to play TV here is a short review. Terminal Velocity is an addictive fast pace 3D Flight Simulator game. The ship one navigates has a mean to accelerate or down-accelerate flying speed. There is also an AFTER BURNER mode which accelerates the ship movement speed drastically while in use. TRI's AFTER BURNER game feature create unique feeling whilst in game, raising gamers adrenaline and giving feeling of great dynamics 😉 The game graphics are a bit low, the game can be switched between VGA and SVGA from within the internal game menus, anyways for the year 1995 the game graphics looks fine.
TV supports network games of up to 8 Network Players and for 1995 is among the few 3D games supporting so high number of network players simultaneously. As most of the games of its time TRI supports modem network game play. I don't know about you, but for me Modem Network game DooM peered plays brings up some nice memories 🙂
The ability to enter Tunnels while in the midst of the game makes TV unique and sets it apart from the rest of the games which were bombarding the 3D game flight simulator market in '95s. Terminal Velocity MINIMUM HARDWARE REQUIREMENTS are:
486 with 8 megs of memory.
For SVGA graphics (provided only by registered game version) require 486 DX4/100 or Pentium to display at acceptable frame rate.
This requirements are nothing and even looks funny while compared to today's available hardware. Nowdays an Android ver. 2.2 OS running (PriVileg) mobile "smart" phone runs at at least 400 Mhz CPU and has a giga of memory. Its quite interesting to see (from historic point of view) how thoroughful the TV Help manual is, and how well organized software documentation used to be in these old DOS days. If you want to take a look at it launch TVHELP.EXE (you will notice it along with other game .EXE files after extracting)
The game soundtrack is amazingly cool and is one of the main things that add to the great gaming experience.
It took me a while to find Terminal Velocity, as the game download link provided on 3drealms.com/downloads is broken and most of the websites with mirror of 3dtv12.zip file was no longer active.
After about half an hour of search!, I've finally found and managed to download 3dtv12.zip. In order to preserve Terminal Violocity game from disappearing I've made a mirror of 3dtv12.zip you can download from here
Thanks to dosbox DOS Emulator , is playable on both GNU / Linux, FreeBSD, Mac OS and Windows. I did not have the time to check if the game runs fine on other operating system architectures besides mine – a Debian GNU / Linux codename (Squeeze). On my aptop Thinkpad R61 with hardware configuration (Dual core x 1.8 Ghz with 2 GB of Memory), the game runs smoothly with both good playable graphics frame rate and properly timed sound/music.
For all those who want to play the game in the Linux realm, you will have to have earlier installed dosbox dos emulator. Once dosbox is there you can further proceed download / unzip / run and enjoy Terminal Velocity on your Linux Desktop:
Full access on the first call. Simple, short and to the point newuser
questionaire. Over 50 door games online, all of them are registered.
Fun RPG games like LORD, Usurper, TEOS, Trade Wars, Clans, and Quest for Nora.
Strategic war games like BRE, FE, Global Wars, ISA, and Colonies.
Adult door games like Strip Poker, Bordello, Studs and Studette.
...
After unzip is complete you will have the following list of files and directories:
hipo@linux:~/TV$ ls -1

As you can read in the unzip notice the .zip file was taken from Telnet/web: lightningbbs.com I was happy to find out that lightningbbs.com BBS is still up and running in both web and telnet mode! I took the time to telnet to lightningbbs.com and it was charming. lightningbbs.com is a real place of "living computer history"!

2. Run and enjoy Terminal Velocity 😉
The game itself is extracted automatically in TV sub directory. To launch it directly enter TV/ and run GAME.EXE , e.g.
hipo@linux:~/TV$ cd TV/
hipo@linux:~/TV/TV$ dosbox GAME.EXE
Running the game through the game launcher TV.EXE or GAME.EXE worked but the game sound was missing music and sound FX 😐 The no-music and sound issues were however pretty normal and expected. Back in the DOS era setting your exact Sound Card device type was required before the first game launch. Configuring the exact screen resolution (EGA / VGA / SVGA) and Sound Blaster or PC Speaker type (Sound Blaster 16 / Sound Blaster Pro) in TV is done through running SETUP.EXE .
Actually SETUP.EXE used to be like a standard for almost all DOS games I've encountered.
To make Terminal Velocity sound work I had to choose from SETUP.EXE main menu: Sound Setup -> Sound Blaster 16
or
Sound Setup -> Sound Blaster Pro
Choosing any of the two SBs produces the same sound / music effects. I guess this is the case becase dosbox emulates a number of sound cards compatible with soudn blaster. After choosing the SB you should select Save and Launch TV to run the game with sound.
If you quit the game and try to relaunch it with dosbox GAME.EXE unfortunately runs the game without sound fx and music again. Hence the only way to make TRI run properly with music is to everytime configure sound blaster type with SETUP.EXE . TV also supports joystick and it was nice my Genius JoyPad worked like a charm with TV under dosbox emu 😉 To play the game in full screen mode with dosbox press ALT + ENTER simultaneously.
An interesting fact which is not related to the game is Terminal Velocity is a physics term, here is a quite from Wikipedia:
"In fluid dynamics an object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the fluid through which it is moving."
On 3drealms.com, I've found also a collection of Terminal velocity mod music – tvmods.zip. For the sake of preservation tvmods.zip from disappearance I've made a mirror of tvmods.zip on here
TV has also 20 cheat code words which can be typed in while playing the game for various goodies like Invisinbility, Shield Restore, Power up all weapons, skip level etc. Complete list of Terminal Velocity cheat codes is here If you're an absolute TV addict and you want to set a TV screenshot on background Check the TV Planet 1024×768 Background resolution
TV has also a game editor, could be valuable if you want to make yourself some custom game levels here is a mirror you can download tvcad10.zip. I've made also a quick research if someone in the Open Source / Free Software realm is not busy working on a fork of TV, but as of time of writting it seems there is no effort to make an "open source" Terminal Veolocity game. As TV is starting to disappear from the scene and 3DRealms are not existing for so many years now, it would be nice/wise if the company publish some of their prior games source. If they don't, so many great games (like TV)'s source code will be probably lost in max 10 / 15 years time.
We know 3DRealms release some of their source code for Duke Nukem 3D, I think it is now time to release source of TRI and the other old forgotten games.
!!! IMPORTANT UPDATE COMMENT INFO DETECTOR IS NO LONGER SUPPORTED (IS OBSOLETE) AND THE COUNTRY FLAGS AND OPERATING SYSTEM WILL BE NOT SHOWING INSTEAD,
I've come across a nice WordPress plugin that displays country flag, operating system and web browser used in each of posted comments blog comments. Its really nice plugin, since it adds some transperancy and colorfulness to each of blog comments 😉 here is a screenshot of my blog with Comments Info Detector "in action":
Comments Info Detector as of time of writting is at stable ver 1.0.5. The plugin installation and configuration is very easy as with most other WP plugins. To install the plugin;
To enable the plugin Navigate to; Plugins -> Inactive -> Comment Info Detector (Activate)
After having enabled the plugin as a last 3rd step it has to be configured.
3. Configure comment-info-detector wp plugin
By default the plugin is disabled. To change it to enabled (configure it) by navigating to:
Settings -> Comments Info Detector
Next a a page will appear with variout fields and web forms, where stuff can be changed. Here almost all of it should be left as it is the only change should be in the drop down menus near the end of the page:
Display Country Flags Automatically(Change No to Yes) Display Web Browsers and OS Automatically (Change No to Yes
After the two menus are set to "Yes" and pressing on Save Changes the plugin is enabled it will immediately start showing information inside each comment the GeoIP country location flag of the person who commented as well as OS type and Web Browser 🙂
I had to setup a QMAIL auto reply (Out of the Office) message on 5 email addresses and since I haven't done it for a long time it took me a couple 20 minutes to consult Qmail (Life With Qmail http://lifewithqmail.org (great website!) documentation and read a couple of online forum threads until I finally remembered, how I used to be setting up a vacation message manually via qmail's .qmail file.
Of course Setting qmail auto reply can always be done via QmailAdmin or VQadmin .. – Qmail Vpopmail web frontends however on many Qmail mail servers Qmailadmin or/and VQadmin is absent due to some reason or even on a big mail servers the server doesn't run Apache at all. Hence it is good to know how to set qmail vacation message directly via plain SSH terminal connection and this is why how this article got born.
So here is how I enable qmail auto reply "manually", through .qmail for my email address info@my-email-domain.com:
1. Set a /var/vpopmail/domains/my-email-domain.com/info/.qmail file with the following content:
Then put with vim or mcedit etc. an auto-reply vacation message similar to the sample below:
From: info@cadiainsurance.com Subject: We have received your message. Thank you!
Dear Customer, we thank you for the interest in our services.
A member of our team will reply promptly to your enquiry shortly.
4. Set proper permissions for vacation/message and .qmail files
/home/vpopmail/domains/my-email-domain.com/info/vacation/message and /home/vpopmail/domains/my-email-domain.com/info/.qmail files has to be owned by user/group vpopmail:vchkpw, e.g.:
If you are a qmail administration with the requirement to create auto reply message for employees going on a holiday often (in a middle sized company office), setting up the out of the office auto reply manually one by one is a time consuming, annoying task and "crazy" task. Therefore some time ago while still I was employed in a Bulgarian mid-sized company called Design.BG, I've written a tiny shell script which creates qmail email users vacation messages by passing few arguments.
Here is my create_vpopmail_vacation.sh shell script Note that this script might have a lot of bugs and is not much tested, so read it carefully and test it before you put it for daily use 😉 Happy Hacking! 😉
I'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:
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.
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!

Does your camera show video correctly in cheese but shows captured video upside-down (inverted) in skype ? This is an issue a friend of mine experienced on his Asus K51AC-SX037D laptop on both Ubuntu and Debian Linux. As you can see in the picture above it is funny as with this bug the person looks like a batman 😉 As the webcam upside-down issue was present on both latest Ubuntu 11.10 and latest stable Debian Squeeze 6.02, my guess was other GNU / Linux rpm based distro like Fedora might have applied a fix to this weird Skype inverted video (bat human like) issue. Unfortunately testing the webcam with Skype on latest both Fedora 16 and Linux Mint 12 appeared to produce the same webcam bug.
A bit of research for the issue online and try outs of a number of suggested methods to resolve the issue led finally to a work around, thanks to this post Here is few steps to follow to make the webcam show video like it should:
1. Install libv4l-0 package
root@linux:~# apt-get --yes install libv4-0
...
Onwards to start skype directly from terminal and test the camera type:
This is the work around for 32 bit Linux install, most people however will probably have installed 64 bit Linux, for 64bit Linux installs the above command should be little different:
3. Edit the Skype gnome menu to substitute /usr/bin/skype Skype Launcher with /usr/local/bin/skype
Gnome 2 has a handy menu launcher, allowing to edit and add new menus and submenus (menus and items) to the Application menu, to launch the editor one has to click over Applications with last mouse button (right button) and choose Edit Menus
The menu editor like the one in the below screenshot will appear:
In the preceeding Launcher properties window, Command: skype has to be substituted with:
Command: /usr/local/bin/skype
For console freaks who doesn't want to bother in editting Skype Launcher via GUI /usr/share/applications/skype.desktop file can be editted in terminal. Inside skype.desktop substitute:
Exec=skype
with
Exec=/usr/local/bin/skype
As one can imagine the upside-down video image in Skype is not a problem because of Linux, but rather another bug in Skype (non-free) software program. By the way everyone, who is using his computer with Free Software operating system FreeBSD, Linux etc. knows pretty well by experience, that Skype is a very problematic software; It is often a cause for system unexpected increased system loads, problems with (microphone not capturing), camera issues, issues with pulseaudio, problem with audio playbacks … Besides the long list of bugs there are unexpected display bugs in skype tray icon, bugs in skype messanger windows and at some rare occasions the program completely hangs and had to be killed with kill command and re-launched again.
Another worrying fact is Skype's versions available for GNU / Linux and BSD is completely out of date with its "competitor" operating systems MS Windows, MacOS X etc. For people like me and my friend who want to use free operating system the latest available skype version is not even stable … current version fod download from skype's website is (Skype 2.2Beta)!
On FreeBSD the skype situation is even worser, freebsd have only option to run Skype ver 1.3 or v. 2.0 at best, as far as I know skype 2.2 and 2.2beta is not there.
Just as matter of comparison the latest Skype version on Windows is 5.x. Windows release is ages ahead its Linux and BSD ver. From a functional point of view the difference between Linux's 2.x and Windows 5.x is not that much different, what makes difference is is the amount of bugs which Linux and BSD skype versions contain… Skype was about 6 months ago bought by Microsoft, therefore the prognosis for Skype Linux support in future is probably even darker. Microsoft will not probably bother to release new version of Skype for their competitor free as in freedom OSes.
I would like to thank my friend and brother in Christ Stelian for supplying me with the Skype screenshots, as well as for being kind to share how he fixed his camera with me.
How to show country flag, web browser type and Operating System in WordPress Comments
Wednesday, February 15th, 2012!!! IMPORTANT UPDATE COMMENT INFO DETECTOR IS NO LONGER SUPPORTED (IS OBSOLETE) AND THE COUNTRY FLAGS AND OPERATING SYSTEM WILL BE NOT SHOWING INSTEAD,
!!!! TO MAKE THE COUNTRY FLAGS AND OS WP FUNCTIONALITY WORK AGAIN YOU WILL NEED TO INSTALL WP-USERAGENT !!!
I've come across a nice WordPress plugin that displays country flag, operating system and web browser used in each of posted comments blog comments.
Its really nice plugin, since it adds some transperancy and colorfulness to each of blog comments 😉
here is a screenshot of my blog with Comments Info Detector "in action":
Comments Info Detector as of time of writting is at stable ver 1.0.5.
The plugin installation and configuration is very easy as with most other WP plugins. To install the plugin;
1. Download and unzip Comments Info Detector
linux:/var/www/blog:# cd wp-content/pluginslinux:/var/www/blog/wp-content/plugins:# wget http://downloads.wordpress.org/plugin/comment-info-detector.zip
...
linux:/var/www/blog/wp-content/plugins:# unzip comment-info-detector.zip
...
Just for the sake of preservation of history, I've made a mirror of comments-info-detector 1.0.5 wp plugin for download here
2. Activate Comment-Info-Detector
To enable the plugin Navigate to;
Plugins -> Inactive -> Comment Info Detector (Activate)After having enabled the plugin as a last 3rd step it has to be configured.
3. Configure comment-info-detector wp plugin
By default the plugin is disabled. To change it to enabled (configure it) by navigating to:
Settings -> Comments Info DetectorNext a a page will appear with variout fields and web forms, where stuff can be changed. Here almost all of it should be left as it is the only change should be in the drop down menus near the end of the page:
Display Country Flags Automatically (Change No to Yes)Display Web Browsers and OS Automatically (Change No to Yes
After the two menus are set to "Yes" and pressing on Save Changes the plugin is enabled it will immediately start showing information inside each comment the GeoIP country location flag of the person who commented as well as OS type and Web Browser 🙂
