Samsung Galaxy S3 , first day of use

There is no reason to introduce the flag ship of Samsung here, everyone knows what’s packed in and all other parameters.

What they did not tell ya is how it feels.

Now I was determined to buy the SGS3 mainly for the reason I had SGS1 , and I do love the phone. It did deliver superb service over the 2 years of use.

So this will be something like Samsung Galaxy S1 vs Samsung Galaxy S3 review.

I didn’t like S2 because it was not so round as S1 was so I didn’t upgrade year back, but S3 looks exactly like over-sized and squashed S1 ūüôā .

Raspberry Pi and GPIO

I had very good time with my RPi (Raspberry Pi) computer, few days with reinstalling and testing it’s performance, however the main reason for my purchase was the available GPIO that can be used for … anything.

My application of the GPIO will be in home security. ¬†Since the RPi will be mainly used as mumble (voice chat like teamspeak) server for my gaming purposes it will be always online and thus why not to add more functions to the home server ? ūüôā

I had found old ribbon cable with MIDI PORT at one end and connector that can be used with RPi GPIO port pins on the other end. The midi connector part was cut so I got my cables and since I intend to use only 2 of the GPIO ports it does not matter that my connector is 10 pins short ūüôā ¬†The other end will go to magnetic sensors. And with use if the GPIO and RPi I can be notified anytime via e-mail if the security of my home will be breached.

You can see in the picture how does my setup look like.

Now I was looking around the net for easy GPIO access software and some suggested some weird stuff that needed just to much guff to be installed, until I found the most easy method using just shell commands.

So I got together some very easy shell script that will show the status of all the GPIO ports of RPi that were ment for such use.

And here it is :

Intro to Raspberry Pi

The waiting is over, and my unit finally arived today. I had ordered it at 29.feb.2012 around 10:00 when the servers came up after the overload shok from users which were interested in purchase.

Well if it was worth 39‚ā¨ with taxes and shipment, only time will tell.

You probably shake your head now and have no idea what I talk about, you might want to have a look at www.raspberrypi.org¬†or read more here. Well in short, it’s miniature 30‚ā¨ personal computer with everything you might need, here are some quick specs:

 

 

 

 

 

 

 

 

CPU : ARM1176JZF-S 700 MHz  , RAM : 256MB on chip , VGA : Broadcom VideoCore IV , HDMI & cinch video output, 2X USB and 1x LAN , 1x SD CARD slot

Sure there is more , however those written above are the most important.

This computer is powered by any mobile phone charger using micro USB connector, which is excellent because I have several of them at home. ¬†What is the computer capable of ? , well as the creator of RPi said, “it’s like computer from -10 years” however does not cost that much.

I am currently in progress of testing of this machine, looks pretty fast however in graphical mode does not seem so great, maybe drivers need to be updated. Anyways , I will be testing this unit for next few days and once I know the perfect solution for any user I will post some tutorials with links pictures etc.

 

Happy 8th birthday UAC !

Universal anti cheat, or in short UAC was created for the first time around end of year 2005, the inital name was SW4TCH and it was ment only for game SWAT4.

The anticheat was a form of IRC client that was able to send screens of the game play to “requester” and scan any user ¬†on¬†request. Detection system was very simple but it was functional to some extent.

First public version of SW4TCH was released at 13.feb.2006.

SW4TCH GUI

The SWAT4 comunity was full of cheaters so any kind of anti cheat was salvation. However SW4TCH did not grow popular and there were only 50-100 users who used this anticheat.

That was no showstopper for me, and I had grasped for more simple solution. Anticheat that did only screenshots.
That’s where UAC1 was born.
It was released at 19.apr.2006 and at the time, everyone liked it, it was simple and it provided the minimal protection of screenshots.

UAC1 GUI

Soon it was not enough, at 13.jul.2006 UAC1 was transformed in to UAC4SWAT , it combined the user friendly GUI of UAC1 and detection system of SW4TCH.

That was the starter of the whole UAC project as we know today. Initial site of UAC was www.uac4swat.com.
Soon after release, UAC4SWAT was used in every existing SWAT4 league and grew very popular.

At some point in year 2006 I was contacted by Snipes who was league admin at Clanbase at the time and he did propose that he will create¬†online database system that will log user logins, screentimes, ip’s etc.
At first it was only for informational purpose and players did not had any access to this database.
However due to vast usage (about 8000 users) we had gathered extreme amount of data.
Snipes  built a site that was displaying this data to all administrators and it did not contain any useful stuff, only time of scans , detections etc.

UAC4SWAT GUI

Approximately month after that, Snipes created pages for UAC where users needed to register (yes, all previous UAC’s were used without¬†registration) and thus new site was started (www.uac4swat.net).

The site grew up to 15000 users, and there were many of updates and changes that made it almost perfect.

UAC4SWAT Site

Site was active for 3 years, and I was continuously contacted by several leagues to create the same anticheat also for their game like¬†Call of duty 2 and counterstrike.¬†So we decided to build “Universal AntiCheat” for all games and not just SWAT4.

The development of UAC2 started around December of 2008, Snipes created new site and I created the application, with much better detection system and the same old well known interface.

The development  lasted around 4-5 months and we had apx.10 internal testers and translators.
Due to vast feedback from users, UAC2 was optimized and changed so all BUGS and twists that users hated about UAC4SWAT were removed.

UAC2 GUI

1st public beta of UAC2 was released at 15.jun.2009 20:00 CEST , it was a blast !
Everyone started to use it, supported games portfolio grew exponentially (32 supported games).

New site was www.uac2.com
It was almost perfect.
Though due to vast use, we had stumbled upon some major issues.
Since our service was FREE of any charge and we want to keep the cost as low as possible, we had used all the time just basic commercial hosting that was not suitable for such vast usage.
Database was super slow after time, there was no space where to store the screenshots and server was easy overloaded if there were 100+ users online.

We switch several hosting companies and nothing had really solved our issue, we only avoided inevitable.
In september of 2010 hard drive of our server crashed, we lost almost all data, backups were around 1 month old.

At this time Snipes decided not to continue on UAC development due to personal issues and due to fact that it was extremely time consuming.
Nobody was up to the task to fix our site and database.

After a week or two, my friend and colleague had volunteered for the task, however he was not aware what is ahead.
It was shii, he fixed the UAC2 site and proposed several changes that inspired me to create UAC3, much more secure and tuned anticheat.
That’s where it started, shii had built a whole new site and we decided to move to cheap dedicated server hosting.
Development of UAC3 was fast, because it was reprogrammed UAC2 with additional detection system and functions and much more optimized for multi game use than UAC2 where 3-4 games were expected to be used.
At 4.dec.2010,we had started new site and 1st public BETA was released.early_uac3

UAC3 GUI

It was a major success, the improvements done were superb and UAC3 was accepted by many leagues and the user base has grown unexpectedly.

Also site and database was optimized to the extreme, and since we had dedicated server we had tweaked the OS of the machine to give us the needed performance so we can provide good and fast pages.

At first UAC3 had domain name www.uac3.com , however the numbering concept within the domain name is not practical so we moved permanently to www.uac.ac where also future UAC’s will have their homepage.

We do not stop here !

Over the time of UAC3 existence we gathered even more requests for functions, changes and many experience what players/admins want and need.
We designed very advanced detection system ever used in UAC series and from old detection systems only small fraction was left for the¬†next generation since the new system used is so much better and accurate even for the most hard to detect cheats.¬†And sadly I can’t show you any pictures of the next UAC due to copycats.

It was decided, work on UAC4 has started, with excellent results after 3 months of testing, the development did slow down and stopped.
That was partially due extreme amount of work needed around UAC3, our user base was doubled (around 200 000 users) and there are just to much things to deal with every day.

Does not sound much to you? well we are only 2 guys working on app that is used by 200 000 users… imagine the amount of work.
However the major slowdown is caused by me, I had many personal things to deal with.
Now it is almost over and rest assured UAC4 will be released even when there is no release date set yet.

[2013 update]

The user base grew +72 000 users (272 014 total) over the year 2012 , we had added support for 8 new games over the period of 12 months and updated the cheat definitions with over 200 new cheats definitions (all games together).

Since everyone is always asking about UAC4 , I have to tell you that it is still in works. I had already started to make definition files, for SWAT4 and CoD4 which are already finished, swat being my favorite and CoD4 the most popular.

There is yet a lot to be done regarding the definition files if we want to add support for all the games we are currently supporting, adding CoD4 cheats alone took full 7 hours, not to mention that we have to start to build whole new server side , with features like screens available directly on the website and many more.

if you did get to this point you must be a big fan of UAC since it’s just several lines of boring history ūüôā

Sooooooooo, happy birthday UAC …

Here are some pictures from the last known version of the page:

UAC server maintenance

UAC3On Monday, January 30th 2012, we will be performing a maintenance.
Server uac.ac will be not accessable for few hours.
This has to be done to guarantee the up-time and service you expect from us.

We anticipate that this work will take no more than 3 hours to complete, and will commence at 07:00AM (UTC + 1).

[UPDATE]

The maintenance had ended around 10:30 CEST . We had updated several server components and teweaked few settings.

Our initial tests show 25% improvement in server speed which is great !

4th UAC almost here?

Some time did already pass after I spoke about UAC4. So here are news and updates.

I did told you last time that the status is about 85% finished. Current status is about 87% , so there was almost no progress in the last two months. And why is that?

All the main major stuff is already done, detection systems are in place and working, new definition file layout and system, server Рclient communication. Though we miss one vital part , which is screenshot system. For testing  purposes currently UAC4 uses the same system as UAC3 which has the black/gray screen issue (BSI).

I can’t wait any longer to release UAC4, I already feel the need for several features that UAC3 is missing and UAC4 will have so we can ban cheaters forever and deliver much better detection rate. That is why I¬†decided to continue even with the BSI. The code will be open to changes so after we will have the solution it can be added anytime.

Anyways, the new UAC4 will support games for DX9 at first ¬†SWAT4 after that COD2 and COD4 etc… and we will add support for new games once the def file for them is finished.

So yes.. we are back on track of development!
