Opera 9.5 Review



Pros:
I'm noticing a speed increase. This is a big bonus, as long as it's not delusional.
UPDATE It seems faster cause they turned caching on full blast.
Reading the Opera help forums, people are complaining because Opera doesn't work properly when people browse forums. (Caching is dumb because you need to see the lastest updates).
Nice programming trick Opera Programmers, but looks like it backfired. A little bit of testing would have determined that.


Cons:
Had to get mouse gestures working again.
go to Tools -> Preferences -> Advanced -> Shortcuts -> check the "enable mouse gestures".
They're the best thing since sliced bread.

Another bug is when I click 'edit' to edit a post in tv, an older version of the post is showing up.
It's a caching issue. Pressing F5 brings the most recently posted content.
This might help: go to Tools -> Preferences -> Advanced -> History -> "Check if cashed page is updated on server"
I changed it to update every 5 minutes.

I'm not a big fan of the new look of the tabs. Not as readable.
The skinning is too dark. I changed to the lighter skin look, it's more natural:
go to Tools -> Appearance -> Skin tab -> Windows Native.
You can revert back to the old 9.27 skin look if you want to also.

Installing Torrentflux-b4rt on Ubuntu/Debian

Torrentflux is an excellent torrent creation, downloading, and seeding program that is used in Linux, and is especially helpful in a multi-user environment, as it maintains separate directories for everyone with an account. That being said, let's get started! In order to have a working install of torrentflux, you need a LAMP (Linux, Apache, MySQL, PHP) installation (I should note that lighttpd will work in place of Apache, but for this guide, we're going to use Apache). Let's start with that. (NOTE: if any commands come back with permission problems, simply add sudo to the front of the command, e.g. sudo apt-get rather than just apt-get).

Before doing anything, you should do this:


apt-get update
apt-get upgrade



This will bring your install up to date on all of the installed components (chances are, any box you've gotten from a provider is not up to date, so this is a necessary step).

Now, installing a LAMP.


apt-get install apache2 php5 php5-mysql mysql-server php5-cgi



Now that we've installed a LAMP, we need to set up MySQL. First, we create the root password for MySQL.


MYSQL_PWD=putapasswordhere (I strongly suggest not using your machine's root password)



To verify the entry of the password, we type:


echo "Your password for the root account of MySQL will be : '$MYSQL_PWD'."



What's echoed should be what you put in above. Next, we tell MySQL what password to use.


mysqladmin -u root password "$MYSQL_PWD"



Now that we have that all taken care of, we need to create a database for torrentflux to use. We do this by naming the database:


MYSQL_DB=putadatabasenamehere (I normally just use torrentflux as my database name, but you can choose whatever you want)



and then creating it:


echo "CREATE DATABASE IF NOT EXISTS $MYSQL_DB DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_unicode_ci" \
| mysql --user=root --password



The password that it will ask for above will be the root password you defined in the first step of setting up MySQL.

Now, we need to actually create a user (and their subsequent password) to use the database. We do this by:


MYSQL_USERNAME=putausernamehere (up to you what to use, but remember what you put here)
MYSQL_USERPWD=putapasswordhere (again, I strongly suggest a different password than what's already in use)



To make sure the information you've put in is what you want, we'll ask the system to echo it back to us:


echo "The user account allowed to manage the '$MYSQL_DB' database is '$MYSQL_USERNAME' with password '$MYSQL_USERPWD'."



Now that we've created a user and password, we have to create that user in your new database.


echo "GRANT ALL PRIVILEGES ON $MYSQL_DB.*
TO $MYSQL_USERNAME@localhost
IDENTIFIED BY '$MYSQL_USERPWD';" | mysql --user=root --password



This will again prompt for that password we created when we first started setting up MySQL. Now, our work with MySQL is pretty much done. Now we move on to installing torrentflux itself.

First, we start off with installing its dependencies:


apt-get install bzip2 php5-gd php5-cli unrar-free grep python \
net-tools mawk wget unzip cksfv vlc-nox uudeview python-psyco python-crypto \
libxml-simple-perl libxml-dom-perl libdbd-mysql-perl libdigest-sha1-perl \
bittorrent bittornado



Once that's done, we can get to the nitty gritty install. First, we want to download torrentflux-b4rt:


cd /tmp/
wget http://download.berlios.de/tf-b4rt/torrentflux-b4rt_1.0-beta2.tar.bz2



Now, we need to extract it:


tar -xjf torrentflux-b4rt_1.0-beta2.tar.bz2 (alternatively, you can type torrent and press tab, and it should autocomplete the whole name of the file for you, assuming you don't have any other files in the /tmp/ directory with similar names



Now, we need to move torrentflux to its home:


mv torrentflux-b4rt_1.0-beta2 /opt/torrentflux



Now, we want to create a symbolic link from it's home to a place where the web front-end is visible and available to the HTTP server:


ln -s /opt/torrentflux/html /var/www/torrentflux



Now we need to make the configuration file writable by the webserver:


chown -R www-data:www-data /var/www/torrentflux/inc/config/



Now we need to create the download folder for torrentflux. Some things should be considered before doing this:

1. Are you going to be running an FTP server on this box as well? If so, you should make the torrentflux download directory the root of that FTP server
2. Are you going to be using glftpd as your FTP server? If so, I strongly suggest using /glftpd/site/ as your download directory.

That being said, let's assume you're not using any FTP server at all.


mkdir /var/lib/torrentflux



Now, we need to make it writable by the HTTP server:


chown -R www-data:www-data /var/lib/torrentflux



Most of the work through PuTTY is done. Now, we need to go about configuring it.

Before we do that, we want to restart apache to make sure it has everything loaded that it needs to.


/etc/init.d/apache2 restart



Once that's done, go to your web browser and type:


http://ipofyourbox/torrentflux/



This should forward you directly to setup.php and you can begin there. If it doesn't, simply add setup.php at the end of the above url.

For the most part, the web interface is self explanatory:

When prompted for what type of database you're going to use, use MySQL.
When prompted for the database information for your MySQL database, remember what you named the database, the user you created for it, and the password you created for that user.
[1*]Uncheck the box for "Create new database"
When asked what the Download location will be, use the directory you specified above (this guide has /var/lib/torrentflux as that directory)
On the software dependencies screen, you may have an error for unrar. That's ok, as we'll just adjust that after torrentflux is running. On Debian, VLC may show an error as well..this is ok, as you likely won't be using VLC.
At the completion of the configuration, it will tell you that it could not delete setup.php. This is normal. We'll be doing that manually.

Now, we remove setup.php.


rm /var/www/torrentflux/setup.php



Then, we make it so that the HTTP server can no longer right to the config folder:


chown -R root:root /var/www/torrentflux/inc/config/



We're just about done! Go back to your browser and type:


http://ipofyourbox/torrentflux



This should autoforward to login.php. If it doesn't, simply put login.php at the end of the url.

The first account you'll create is the superadmin account. This account is the only one that has all the features in it. I suggest using admin as the username, and a strong password for the password.

Once logged in, there are a lot of things to play around with, and ultimately, it's up to you to adjust as you see fit. The first page you'll want to look at is the server page, and adjust the unrar dependency. Simply add -free to the end of it, and you'll be fine with that.

Secondly, you'll want to look at the transfer page, where you'll want to adjust the max bandwidth for your connection (e.g. 12500 for a 100Mb connection). Alternatively, you could just put 0 and let it use the max available bandwidth. The rest of the settings are really up to you (I also strongly suggest using bittornado as yoru default torrent client).

That pretty much sums up this guide for installing torrentflux-b4rt.

Speed up downloads - increasing the half-open TCP limit in XP SP2 and Vista

Now if your new to BitTorrent, you might be new to downloading. If so you should know that Microsoft introducted a limit to stop many TCP connection attempts in XP SP2. This well-intentioned modification came as an attempt by Microsoft to limit the speed at which malicious worms (such as the infamous ‘Blaster’) could spread.

However, for software that relies on many connections such as bittorrent applications, this limit has the potential to cause slowdowns in certain situations. So what you want to do is change the half-open limit to a higher number.

For Windows XP SP2: http://www.lvllord.de/?lang=en&url=downloads
unzip it to your desktop and then run the .exe file. Follow the instructions and then change your limit to 75 or higher. Make sure you restart your computer immediately after it is finished--like it tells you.

For Windows Vista: http://www.yaronmaor.net/repair.htm
choose the right fix depending on your version of your tcpip.sys file.

There, now you will certainly increase your download speed, and possibly your upload speed as well.

The Future of Artificial Intelligence

Artificial Intelligence is a term that has suffered from a lot of inflation the past years, with too many companies gladly and freely using the term for marketing to describe their (most definately not "AI") products. That probably has put many off.

This must be very frustrating for researchers in cognitive engineering and neuroscience because really massive steps forward are being made in understanding how the brain works thanks to their hard work.

Understanding how consciousness is formed is of course not the same as simulating it on a computer.
Still, thanks to this understanding expect many steps forward with adaptive / learning / evolving algorithms. These will find their way in the near future into robots, neural prosthetics, UAV's, image recognition, automonous vehicles, your washing machine and much more.
Look on the site of DARPA (always a good indicator) and you'll see the importance the US Army is placing on "intelligent" technologies.

So yes it is the future. But more in terms of a strategic direction than actual products.

Choosing a Content Management System


I have had direct experience with Mambo, Drupal, Apache Lenya, WordPress, Plone, and Zope on everything from small company websites to sites served to millions of users. Here are a couple angles that I keep in mind when selecting the right CMS for any given job:

* How do you want to use it? Many people get hung-up on features lists, pitting various CMSes against one another in a matrix of checks and X's, but this is almost always misleading. You don't seem to be heading down that particular rabbit's hole when you say you want to "edit/change/add/remove pages," but it can become tempting. Writing down some quick use case scenarios can be a good way to stay on track. For a basic CMS I would steer clear of Drupal (even though I'm quite fond of it ;) or Zope and prefer something like WordPress or MovableType.

* How do you foresee your site growing? Drupal and Zope provide a "everything and the kitchen sink" approach that gives you quite a bit of flexibility, but the trade-off is that they assume a certain technical sophistication. Correspondingly, WordPress or MovableType are excellent choices for small sites where workflows are simple or nonexistent, but if you have a need for complex workflows or integrations then they can become constraining. Thinking now about your future needs can save you the pain of a migration later on.

* How do you want to publish to the site? If you want to make changes instantly on the site and don't plan to stage your content, then WordPress, Drupal, or MovableType are good choices. On the other hand, if you need to stage it prior to deploying it to your production site then Apache Lenya would be a good fit, although its learning curve is steep. The trend these days is away from staging content, but sometimes performance considerations or an organization's culture demand it.

* What kind of support, if any, do you want for your CMS? Some CMSes have small consulting industries surrounding them, or are sponsored by a commercial entity that provides support. If it is important to you to be able to pick up the phone and call someone when things break then you should survey the field before selecting a CMS.

Learning curve for C programmers : C++ vs Java


All other things being equal ... actually, all other things are hardly ever equal, so it would be good to know more about your goals. (In particular, what performance goals do you have? Are you doing hard real time systems? Games? Web development? More rapid development is always better than less rapid development, but how much development speed might you willing to trade off for software execution speed? Put another way: If you got your software working, but slowly, what forces would be at play with new features vs. better performance? I'm not saying Java performance is bad, I'm just trying to characterize your goals.)

The Java language is easier to learn than the C++ language. The Java runtime libraries are much bigger (and provide a lot more functionality) than the C++ standard library; and thus, take more time to learn.

Software written in Java is not inherently slow; software written in C++ is not inherently fast.

Tool support is better for Java than C++. Yes, you can use Eclipse for either; but I think Eclipse's Java support is far more mature than its C++ support. I've used Visual Studio and C++, and I've used Eclipse and Java, and I'm far more impressed with the latter. Java compiles much faster than C++. Also, FindBugs is awesome.

The link below shows programming language book sales. Java is the big spike. Make of this what you want.

glftpd and zipscript install guide


So, you need an FTP server on your box, and you don't know which one you should use? I'll solve that dilemma for you. glftpd is easy to install and is a fully functional, fairly robust FTP server.


That being said, lets get started! (NOTE: if any command spits back a permissions error, simply put sudo in front of the command).


cd /tmp/
wget http://www.glftpd.com/files/glftpd-LNX_2.01.tgz
tar -xzf glftpd-LNX_2.01.tgz



Let's grab the dependencies we need to get glftpd to work properly


apt-get install xinetd zip unzip openssl tcpd



Now, we move into the glftpd directory


cd glftpd-LNX_2.01
sh installgl.sh


For the prompts, do:

Use tcpd? [Y]es [N]o: Y
Use a jailed environment? [Y]es [N]o: N
Please enter the directory to install glftpd to [/glftpd]: (press enter) - Installing into /glftpd is the best way to go, imo
Press for the default (glftpd)> (press enter)

The install will then compile (hopefully with no errors).


Enter the port you would like glftpd to listen on [1337]: (pick any port, I suggest something in the higher # range, 40000 plus)
Do you want to use [I]netd or [X]inetd? X
Do you wish to use European weeks? European weeks starts with a Monday.
This is for glftpd's 'reset' binary (see docs for more info) [Y/N]: Y
Please specify location, inside /glftpd, to install the cert (ftpd-dsa.pem) [/etc]: (press enter)
Please specify a generic name for this certificate. This can be any name but should say something about the ftp server like the name for it perhaps (press enter for glftpd): (you can put just about anything here...doesn't matter)


It will then create your certificate. Once that's done, glftpd is almost completely set up.

What you'll want to do next is set up your user account for the FTP. To do this, you:


ftp localhost port
user: glftpd
password: glftpd


This will get you logged in.

Once logged in, you want to create a user, set its flags, set its ratio, set its logins, set its ratio, etc.


site adduser user password ip [e.g., site adduser ronin hdwhore 127.0.0.1) And no, don't use localhost as your IP..was just using that as an example.
site change ronin ratio 0
site change ronin num_logins 0 (if you want unlimited logins to your FTP)
site change ronin flags +1ABCDEFGH


That takes care of the account. Now you're going to want to edit the glftpd.conf. 

To do so, you:

nano /etc/glftpd.conf


There's not much you NEED to edit here, so I'll just highlight what you should.


sitename_long MY[:space:]SITE[:space:]NAME (put whatever you feel like here)
sitename_short MSN (short version of the above
# TLS enforcements.
userrejectsecure !*
userrejectinsecure !* (remove the ! to enable Auth TLS requirements for login)
denydiruncrypted !*
denydatauncrypted !*



The rest doesn't need to be touched, unless you so choose to. CTRL+O, press ENTER, CTRL+X, and you're done editing the file. That completes the install for glftpd. Now, for zipscript.


cd /tmp/
wget http://se.pzs-ng.com/stable/project-zs-ng_r2414-v1.1.0a.tar.gz
tar -xzf http://se.pzs-ng.com/stable/project-zs-ng_r2414-v1.1.0a.tar.gz
cd http://se.pzs-ng.com/stable/project-zs-ng_r2414-v1.1.0a.tar.gz
./configure



When that's done, you need to edit zipscript/conf/zsconfig.h


nano zipscript/conf/zsconfig.h




I recommend changing the following folder listings below:


#define zip_dirs "/site/"
#define sfv_dirs "/site/test/ /site/incoming/mp3/ /site/incoming/games/ /site/incoming/apps/ /site/incoming/musicvideos/ /site/incoming/requests/"
#define audio_nocheck_dirs "/site/groups/ /site/incoming/requests/"
#define check_for_missing_nfo_dirs "/site/incoming/games/ /site/incoming/apps/"




If you don't do music, ignore the auto_nocheck variable

You'll also want to edit:


#define short_sitename "NG"


CTRL+O, PRESS ENTER, CTRL+X, and you're done editing zsconfig.h


make
make install
cd scripts/libcopy/
./libcopy.sh
chmod 666 /glftpd/ftp-data/logs/dupelog (this assumes you installed into /glftpd/)
nano /etc/crontab/
paste the below into your crontab
59 23 * * * chroot /glftpd /bin/cleanup >/dev/null 2>&1
29 4 * * * chroot /glftpd /bin/datacleaner >/dev/null 2>&1



Once that's done, you have 1 more step, and zipscript is complete.


nano /etc/glftpd.conf




Copy/paste this somewhere into your glftpd.conf


calc_crc *
post_check /bin/zipscript-c *
cscript DELE post /bin/postdel
cscript RMD post /bin/datacleaner
cscript SITE[:space:]NUKE post /bin/cleanup
cscript SITE[:space:]UNNUKE post /bin/postunnuke
cscript SITE[:space:]WIPE post /bin/cleanup

site_cmd RESCAN EXEC /bin/rescan
custom-rescan !8 *

cscript RETR post /bin/dl_speedtest

site_cmd AUDIOSORT EXEC /bin/audiosort
custom-audiosort !8 *



CTRL+O, PRESS ENTER, then CTRL+X.

You'll likely want to chmod the incoming (/glftpd/site/incoming) to 777, and any other directory you might dump into:


chmod -R 777 /glftp/site/*


Once that's done, you're done setting up your zipscript.

You now have a fully functioning FTP and file checker installed on your box, and it's ready to be used.

Bit VS Byte....The Broadband Saga

Let's put some light into the bits and bytes discussion.

A lot of people say.... Hey! My ISP said I have 4096/512 kbps speed. So how come, that my torrent client is showing 512/64 kB/s?

It is a simple answer.

Bit is a binary digit, taking a value of either 0 or 1. For example, the number 10010111 is 8 bits long, or in most cases, one modern PC byte. Binary digits are a basic unit of information storage and communication in digital computing and digital information theory.

So, as we see, the smart marketing people paid by ISPs are actually telling the truth. They are talking about bits. And they know, people love big numbers. So why should we say 512 kB/s download, when we can say 4 Mbps (4096 kbps). Huge numbers are better, a lot better for managers and salesmen.

So if you really want to know, what your speeds will be before you sign the next suped duper speed ISP contract, take a calculator, divide kbps by 8 and you will get the torrent client UL/DL speeds.

Here is also some more info about it http://www.t1shopper.com/tools/calculate/ and wikipedia http://en.wikipedia.org/wiki/Bit

Also google.com can help you just enter "4096 kb = ? kB" and change the 4096 with wanted conversion.

Hope this clears things a bit.

How to install rtorrent in Ubuntu


How-to install rtorrent on Ubuntu.


I am just learning about linux myself so bare with me but I have installed rtorrent several times before. Im gonna try and make this as simple as possible. You shouldn't have any problem doing this if you follow step by step. Copy and paste if ya want!


sudo apt-get update


sudo apt-get install build-essential libsigc++-2.0-dev pkg-config comerr-dev libcurl3-openssl-dev libidn11-dev libkadm55 libkrb5-dev libssl-dev zlib1g-dev libncurses5 libncurses5-dev



cd /tmp/


wget http://libtorrent.rakshasa.no/downloads/libtorrent-0.11.9.tar.gz


tar -zxvf libtorrent-0.11.9.tar.gz


cd /tmp/libtorrent-0.11.9


./configure


make


make install


cd /tmp/


wget http://libtorrent.rakshasa.no/downloads/rtorrent-0.7.9.tar.gz


tar -zxvf rtorrent-0.7.9.tar.gz


cd /tmp/rtorrent-0.7.9


./configure


make


make install


If you get any 'access denied' errors just put sudo in front of the command.

Now all you need to do is put a rtorrent cfg file in your /home/name dir. You can grab a cfg file from HERE and edit to your liking.Also make sure you rename rtorrent.rc to .rtorrent.rc so rtorrent will see it. To open rtorrent just type rtorrent from terminal and happy torrenting!

You can find a rtorrent user guide with a list of commands HERE

If for some reason you get this error..."rtorrent: error while loading shared libraries: libtorrent.so.10: cannot open shared object file: No such file or directory" type... sudo ldconfig and it should be golden!

Region-Free DVD-drives, All you need to know


Region-free DVD-Drives can be confusing without full information about them. Already the upload of a simple utility for them has generated some doubts and questions. I have then tried to cover the subject in a simple but all-covering text (at least I hope I achieved both).


This comes from my personal experience and what I read from many sources on the Web. Some subjects I didn't study in depth, so it might be incomplete or slightly imprecise here and there. Still, for its introduction and explanation purposes, I believe it will make no difference.

-------

The holders of the rights for the Movie DVD format (an organization named DVD Forum) impose everyone to implement Region Control. That's in the contract you have to sign with them in order to acquire the information on DVD structure necessary to build a drive or write a player than can play Movie DVDs.
 
Region control means that the drive and player will work together asking for a region choice and storing it inside the drive itself. They will then refuse to play any DVD from a region different from the one you chose. And that they will allow you to change that choice, but for only a limited number of times. They will keep count the changes you made and store it again inside the drive's flash-memory.

You will be able to change the region 5 times only (including the initial choice) then the drive will lock. You will have to send it to the factory where, for a fee, they will reset the region counter and give it back. This is called "Factory Reset", it does cost and it too has a counter. It can be done 5 times, then the drive will lock forever. In the end you will be able to change the region of a drive for 25 times, but once every 5 it will require sending it to the factory and will cost money. (it would look like the changes should be 30, but I believe I remember they are only 25. Probably the initial 5-choices-group is already considered like a Factory Reset and its counter starts at 1. This would mean you could actually send it in only 4 times, rather than 5.)

The DVD-drives have some software inside and and also tables of all the writable DVDs and CDs. They hold the proper parameters to burn each kind, together with the maximum speeds that can be reliably used.
This data is written in Flash-RAM. These are memories that can be re-written, but they retain their content even when they are disconnected from a power supply. That's different from standard RAM that forgets everything if power is interrupted.
Once in a while, the factories send out upgrades that rewrite what's stored inside the flash-RAM. This happens to correct bugs, or to implement a more reliable or faster burning strategy, or to add the parameters for a new CD/DVD kind that was just released.

Studying these upgrades (and the firmware inside the drives) some people have been able to find out how the drive software works and ways to deactivate the region block. Usually these "region free" patches are inserted inside one of the original upgrades from the factory.
Some drives have been "cracked" quickly, other ones have resisted for longer times (like the Mat****a mentioned in the RegionX upload description).
A place to look for a patch for your drive might be rpc1.org and in particular The Dangerous Brothers' pages tdb.rpc1.org
These patches generally run on PCs. In the past there has been a guy nicknamed xvi who worked on producing Mac versions of the patches. A couple of years ago he decided to quit, and since then patches have once again been available for PCs only.
Unfortunately these cannot be run in emulators like VirtualPC, GuestPC or similar. Emulators have only a limited access to DVD-drives (they cannot play movies, for example) that is not enough to support patching.
But those patches can be applied to DVD-drives connected externally to a PC and also an Intel-Mac running Windows via a USB-IDE adapter. (I'm sure this works for Pioneer drives, I've done it personally several times. I believe it should work with any other, but have never tried it).

Is patching a drive dangerous? Yes: it will void the warranty and also, if it doesn't work or if it is interrupted midway (a blackout for example) it will leave you with a dead drive that can not be patched again. If you do things with care it is not likely it will happen, yet it could. Current prices have dropped so low that it is no longer a heavy risk, in my humble opinion.
Just for an example, through the years I have successfully patched one Pioneer DVR-105, one DVR-107, one DVR-109, one DVR-110D, one DVR-111D and two DVR-112D. I never had any dead one. Also: for the last three kinds I applied patches that "took the D away", in other words I turned them into the version that can also write DVD-RAM. The difference is only in the firmware (and in the price), not in the hardware.

There is an utility by the famous xvi that can test your drive(s) and report which is region locked (RPC-2) and which is Region Free (RPC-1). It is called DVD Info X, and I'm uploading it at the same time as this text.


BUT... patching the drive is not enough. If you then try playing some other region DVD you will still be stopped by the same alert and still be asked to change region (if you still have region changes left).
Once again it's the player (DVD-player) that is stopping you, but this time it can no longer use the region stored inside the drive (the drive is region-free now). Rather it is using data (region and counter) stored inside itself.
And this is a much much easier problem to solve, because this data is stored on the Mac Hard Disk: a lot easier to reach and modify. There is a program called RegionX, once again by xvi, that deals with it. It has been uploaded here this past day. It does not apply a patch DVD Player, but simply changes its chosen region and at the same time resets its counters. This means that you will have to run it every time you want to change region, but you can do it as often and as many times you need. Also, this kind of approach has high chances of being still working when a new version of DVD Player is released (it already happened more than once). A patch instead would probably have to be revised and re-released every time.


important note: This RegionX program does NOT patch the drive, it will NOT make it region-free. Rather, if your drive is still region locked it will not work on the DVD-player counter but on the one inside the drive!!! This means you will be eating one of the 5 changes available. To make sure you're not doing that, better double-check that your drive IS region-free by using DVD Info X.


Summarizing: 

To be able to play every region DVDs on your Mac you need to do two things:
1. Only once: patch your drive to RPC-1. This needs to be done on a PC or Intel-Mac running Win and using a software specific for your drive.
2. Each time you need, change the region inside DVD-Player using RegionX.

---

Addendum: How comes VLC can play any region even on region-locked drives without ever asking for a choice?

The VLC project was started by a group of students in a Paris university-like school. VLC was and still is freeware. Those students couldn't afford buying the (quite expensive) papers detailing the internal structure of DVDs and/or purchasing a licence. When purchasing that documentation people also have to sign a non-disclosure agreement, so it cannot be redistributed. But others were already experimenting and discovering how a DVD is structured and were publishing that info on the web. Rather the VLC group did it on their own without any DVD-Forum support by using this "other-sources" info. Not having signed any contract with the DVD-Forum they are not bound to implementing any region lock, and so they didn't: they simply totally ignore whatever region choice is stored inside the drive.

Bypassing Comcast Throttling

Hey, all bittorrent users! Want to download from comcast users? Have comcast and want to upload again like the good 'ol days? Want to show comcast that throttling doesn't work? This guide is for you!

The Story Behind This Fix

Sandvine, everybody's favourite "load balancer" works using a simple Man In The Middle attack to stop torrenting. Whenever the unit detects a network connection that fits the profile of bittorrent seeding traffic it injects a pair of forged TCP reset, or RST packets into the connection. When the uploader and the downloader receive the RST packets, they immediately terminate the connection without finishing the transfer. Sandvine targets both sides of the connection, so both sides have to implement the fix.

There is a way to stop this! While we all can agree that sandvine won't be going away anytime soon, we can speed it's demise by rendering it completely ineffective. All you have to do is block RSTs on your bittorrent port(s) and this tutorial tells you how.

How to install and use Irssi (Linux IRC Client)

How to install:
Irssi follows the general Linux installation steps, either (./configure, make, make install) Or through a package system. To install with a package system, type the following commands in the terminal:

Debian Based:
apt-get install irssi

Red Hat Based:
yum install irssi

Gentoo:
emerge irssi

How to use:
To launch irssi just type the following in the terminal:
irssi

If you wish you leave irssi running after you close the terminal/ssh/putty, you can launch it using screen:
screen irssi

After you have closed your ssh client if you want to resume your irssi session use the following command:
screen -r

If you accidentally choose the wrong screen id, press Ctrl+A, loose go and then press D. That will detach you from the screen session and bring you back to the terminal

To get a list of all screen ID's use:
screen -ls

Once you have irssi installed and running, alot of the commands are the same as they are for all clients.

/server - [ Connect to server ]
/join #channel - [ Join a channel ]
/query nick - [ Send a private message ]


I'm sure you get the drift...The one thing irssi lacks compared to almost every other client out there, is a mouse

So to switch between different windows (channels) you press Ctrl+P or Ctrl+N

Note: If you will be connecting to an SSL server you will need to type:

/set use_ssl on

Irssi also allows you to split windows, and display multiple channels at the same time. The four main window split commands consist of:

/window new - [ Open a new split window ]
/window close - [ Close a split windows ]
/window balance - [ Make all split windows the same size ]
/window
- [ Switch control to another split window ]

If at anytime you want to scroll up through the channel text you can use the PgUp and PgDown buttons

Auto Connect on start up and performs.

Like many other IRC clients, irssi supports auto connect and performs. The first thing you have to do to set this up is create a network name using the command:

/network ADD NetworkName

Once this is done you can set up the commands to use on connect with the command:

/network add -autosendcmd '^nick nickname;/msg nickserv identify pass' NetworkName

Seperate all the commands you want sent to the server with a ';'. Once all the commands are entered, you can tell irssi which server to connect to on start up:

/server ADD -auto -network NetworkName irc.host.com 6667

And finally the last thing to do is add the auto join for the channels:

/channel ADD -auto #channel NetworkName password

Videogame Programing

Here are some sites that might help you with SDL and OGL coding.

Most of them have tutorials with detailed walkthroughs and sample code .. all you need

NeHe

Cone3D Programming - SDL, OpenGL and C++ Tutorials

Lazy Foo' Productions

GLUT Tutorial

Anyways if you want really easy tools, go here:
YoyoGames

3d game maker studio is a little more technical. You can download it from any major torrent site. It takes a little getting used to though.

Other than that, I would suggest just doing your own research. I've had teachers who think they know what the game industry is like, only to have another teacher completely contradict them. Independent research is the best way to go. I suggest looking at the sites everyone has already mentioned, gamedev.net is great, and branching out from there.

Ebook Management Tool

Manage your E-book collection

MediaMan

It does everything you want and more. Well worth the $40 price tag, IMHO.

It has one or two quirks that I wish it didn't, like not being able to merge multiple collection files into one, but the pros far outweigh any cons and a major upgrade is due later in the year, so hopefully, this will be among the improvements.

It's been out for several years now, but is still relatively little-known. Is developed and supported by a lone programmer, who is so obviously committed to it, which is nice to see and another reason I don't mind the price tag.

Not only will it handle your ebooks, but your videos, music, DVDs, games and software.

The really neat thing is its Amazon e-commerce engine, which pulls down descriptions, ratings, images, metadata and all that good stuff within seconds, at the click of a button.

Unfortunately, no imdb, freedb or worldcat (or similar) support yet, but again, this may change in future.

And to top it off, you can link directly to your files to have them open with your default player/viewer at the click of a button. In the most recent version, you can even play your audio from directly within the program.

More? I could go on, but it's best to check it out for yourself.

For Mac users, check out Delicious Monster

Same price. Older and more polished. But pretty much the same app. Well supported by a dedicated team.

Both awesome in their own right. Sure to satisfy your needs.

C ++ - Avoid video tutorials

Don't use videos to learn how to program. Unless there's a strong visual component to the programming (e.g. ActionScript, CSS) it will be a waste of your time. The best way to learn C++, or any other multi-purpose language, is with a good book and a good compiler side-by-side.

If you *really* want to learn C++, and already know some other multi-purpose language, then there is no book better than Koenig and Moo's "Accelerated C++". Period. They teach C++ the way it was meant to be programmed. Most books (Deitel included) teach from a bottom up perspective, which robs C++ of it object orientedness until you reach the later chapters. Additionally, they tend to be 300 page mammoths which you'll never ever finish, no matter how determined you are in the outset.

Accelerated C++ starts you out with the STL: you're face-to-face with OO from page one. They write in a very simplistic, casual, and informal way that is easy to understand and friendly. The book is short. You can really get through it. The whole thing. Cover to cover. And they teach C++ the way it was meant to be written. I can't praise the book highly enough. There is no other book like it.

Once you're done, you'll be ready to tackle the Scott Meyer books (who has a very similar friendly informal style of writing).
