Normally, we can restart x server with CTRL+ALT+BACKSPACE keyboard combination in an older version of Ubuntu.But in jaunty this is not possible because newer version of Xorg disabled this property.So that if we want to re-enable this feature we just have to modify Xorg.conf file,lets do that from console
sudo nano /etc/X11/xorg.conf
then add this 3 line to it
Section "ServerFlags"
Option "DontZap""False"
EndSection
then save the file and quit.Logout and login again, it should be work.
Ruby ile yapilmis sadece algoritma gelistirmeye yonelik bir calisma .Konsol programi olmakla beraber eger istenirse glade ile arayuz yapilip ve ya bir kac degisiklik yapilarak eklenti haline getirilebilir.Ornegin doviz birolari icin verilen paranin miktarini gonderip turkce okunus karsiligini geri gonderen bir fonksiyona donusturulebilir.Herneyse olayin genel mantigini anlatmak gerekirse eger turkce sayilarin okunusuna dikkat ederseniz,ilk uc haneden sonra bundan sonra gelen hanelerin sonuna basamak adi getirilerek devam edilir.Bir kac ornek ; 321 = Uc yuz + yirmi + bir 234754 = iki yuz +otuz +dort - bin – yedi yuz+ elli +dort // goruldgu gibi uc hane seklinde tekrarlaniyor sadece her uc hanede bir basamak adi ekleniyor. Ozel durumlar :
Sifir sayi icinde gecerse okunmaz tek oldugunda okunur.
Normalde iki yuz,uc yuz,dort yuz gibi okundugu halde bir yuz okunmaz
Ustteki duruma benzer olarak bir bin okunmaz buna ragmen bir milyon ve sonrari okunur
Bu durumlar goz onunde bulundurularak bir kod yazmak istersek kisaca yazacagimiz kod soyle olmalidir.Sayimiz kac tane uclukten olusuyor.Bu uclukleri sirasiyla yazdirdiktan sonra (sayi degerini basamak degerini falan bulduktan sonra).Push yapip stack’a atiyoruz her atma olayindan once kacinci basamakta oldugumuzuda konrol edip sonuna ekliyoruz ki pop yaptigimizda sonucumuz sirali gelsin.Peki ama sayimiz ucun kati degilse bu olusacak ucluler patlamayacakmi bunuda en sondaki kalan kisminda tekrar baska uclu varmiscasina ama kac haneli olduguna bakarak ve ozel durumlarin ustesinden geliyoruz.

I have a toshiba u305-s5077 laptop.It had a problem with volume wheel like when i tried to use volume wheel it makes the volume iteratively maximize or minimize(And it has no end).While it is happening i cant write anything or i cant click something.That’s why i had to restart X screen with CTRL+ALT+BACKSPACE.
I search the internet and i found a solution for it.
At first if it won’t work if you don’t want to kill X screen at least you can use this;
Change your status to text mode via using CTRL+ALT+ {F1-F2-F3-F4-F5-F6}.Then turn back X Screen with ALT+F7.
Lets make it works:
Firstly lets create a backup if it wont work or if something goes wrong we can handle it. Read the rest of this entry »
Lets develop mobile applications with using google android SDK.
Firstly we have to download Eclipse (at least i download it ).From Eclipse.Org
after that extract it some where and open Eclipse 3.4 Ganymede
Start Eclipse, then select Help > Software Updates….
In the dialog that appears, click the Available Software tab.
Click Add Site…
Enter this as the Location: https://dl-ssl.google.com/android/eclipse/
Alternatively, you can use http in the Location URL, if you are having trouble with https (https is preferred for security reasons). http://dl-ssl.google.com/android/eclipse/
Click OK.
Back in the Available Software view, you should see the plugin. Select the checkbox next to Developer Tools and click Install…
On the subsequent Install window, “Android Developer Tools”, and “Android Editors” should both be checked. The Android Editors feature is optional, but recommended. If you choose to install it, you need the WST plugin mentioned earlier in this page. Click Next.
Accept the license agreement and click Finish.
Restart Eclipse.
After all these operations lets add our SDK.Download sdk from here
Extract your sdk somewhere and add your sdk’s path with clicking Window->Preferences-Android
then with using browse select your sdk location. That’s it.Lets watch how its simple to write code for mobile phones. Read the rest of this entry »
