now you have ay least >5GB space. for more

also you can edit the maximum allowable ram size for a running program with this guide.

You may change the maximum ram for dedicated to a  running program from 768 to 1024 etc, with the steps below:

To resolve this problem, modify the desktop heap size. To do this, follow these steps:

1. Click Start, type regedit in the Start Search box, and then click regedit.exe in the Programs list.

   Note If you are prompted for an administrator password or for confirmation, type your password, or click Continue.

2. Locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems
3. Right-click the Windows entry, and then click Modify.
4. In the Value data section of the Edit String dialog box, locate the SharedSection entry, and then increase the second value and the third value for this entry.

Notes

• The second value of the SharedSection registry entry is the size of the desktop heap for each desktop that is associated with an interactive window station. The heap is required for each desktop that is created in the interactive window station (WinSta0). The value is in kilobytes (KB).
• The third SharedSection value is the size of the desktop heap for each desktop that is associated with a “non-interactive” window station. The value is in kilobytes (KB).
• We do not recommend that you set a value that is over 20480 KB for the second SharedSection value.

By default, the Windows registry entry contains the following data in an x86-based version of Windows Vista.

%SystemRoot%\system32\csrss.exe
ObjectDirectory=\Windows
SharedSection=1024,3072,512
Windows=On
SubSystemType=Windows
ServerDll=basesrv,1
ServerDll=winsrv:UserServerDllInitialization,3
ServerDll=winsrv:ConServerDllInitialization,2
ProfileControl=Off
MaxRequestThreads=16

Note By default, the second value for the SharedSection entry is 3072 in an x86-based version of Windows Vista. By default, this second value for this entry is 20480 in an x64-based version of Windows Vista.

In Windows Vista and in later operating systems, memory allocations are dynamic. Therefore, there is no limitation for memory allocation. However, if you allocate too much memory to the desktop heap, negative performance may occur. This is the reason why we do not recommend that you set a value that is over 20480.

Note The desktop heap size is not affected by the physical RAM on the computer. Therefore, you cannot improve the performance by adding physical RAM.

Asssume that we have the following example.c code:

#include <stdio.h>
#include <math.h>
int main(void)
{
        double x = 4.0;
        double result = sqrt(x);
        printf("The square root of %lf is %lf\n", x, result);
        return 0;
}

If we compile this code in bash terminal with:

$ gcc -lm test.c -o test

we have an error as undefined reference to `sqrt‘ (or any other function that called from math.h library) Interestingly if we have a static variable inside the sqrt like ‘sqrt(12.2)’ the compiler don’t give us any error. This happens because when we give the gcc  ‘-lm‘ option, we link the libm.a and libm.so to the compiler. “.a" files are static libraries, as opposed to “.so" files which are dynamic libraries. Normally gcc looks for dynamic libraries if available unless passed -static.  In ”sqrt(12.2)” case gcc is called ‘libm.a’ and not call the function sqrt in the run time, simply assign the value to the static variable.

In bash terminal. if we compile this code with:

$ gcc test.c -o test -lm

problem would be solved for bothe cases. to to this in Eclipse:

1. Right click on your project in Project Explorer and select Properties.
2. Go to C\C++ Build -> Settings -> Tool Settings -> Gcc Linker -> Libraries and click on green plus button to add a new library. When the dialog pops up, write m, and Eclipse will automatically add the –Im flag.

 resizebox komutundaki “.9” o sütunun onda olarak kaçta kaçına sığdırmanızı istediğiniz belirtiyor. misal .9 denklemi sütun genişliğinin 9/10 (%90) sığdırılmasını sağlayacaktır 

Güç yönetimi/power management ile ilgili bir sorun bu. bu nedenle Aygıt yöneticisi(Device Manager) altından Bluetooth sekmesine geliyoruz ve buradan donanımımızı çift tıklayıp Power Management/güç yönetimi altsekmesinden “Allow the computer to turn off this device to save power” (Bilgisayarın bu aygıtı güç tasarrufu için kapatmasına izin ver) deki seçimi kaldırıyoruz. Aşağıda ilgili ekran görüntüsü de bulunmakta. taa taaa..

sudo apt-get install xserver-xorg-input-mutouch

ardından, xorg.conf dosyasına birkaç satır bir şeyler ekleyeceğiz. öncelikle xorg.conf dosyasını açalım:

sudo gedit /etc/X11/xorg.conf

bu dosyada aşağıdaki satırları aynen kopyalayıp, oturumu yeniden başlatalım

Section “InputDevice”
Identifier “Touchpad”
Driver “microtouch“
Option “Device” “/dev/input/mouse1”
EndSection

 

bir başka sorun da touchpad i istenildiği zaman açma/kapatma. onun için de buradaki çözümü uygularsanız sorununuz hallolacaktır.

elbette buna da bir çözüm bulunmuş durumda. kernel’de physical adres extension (pae)kullanılarak arttırılabilir. sözü uzatmadan kodları verelim:

öncelikle işlemcinizin pae destekli olup olmadığına bakalım:

$ grep --color=always -i PAE /proc/cpuinfo

işlemci “flag”larında pae kırmızı olarak görünüyorsa işlemcinizin pae desteği vardır. pae desteği ile adresleme için 4 bit daha kazanmış oluyorsunuz. kaba bir hesapla bu normal 32 bit sistemin 2^4=16 katı fazla yani 2^36 bellek gözünü adresleyebileceğiniz anlamına geliyor. zaten günümüzde max 4 ram slotuyla 4x8GB=32GB ram sahibi olabiliyorsunuz. pae desteğiniz varsa devam edelim:

#sudo apt-get install linux-generic-pae linux-headers-generic-pae


ve yeniden başladıp default olarak da seçili olan bu kernel ile oturum açıldığında artık tüm ram’inizi adresliyebiliyor olmanız gerekir ;)

kaldırmak için:

#sudo apt-get remove linux-generic-pae linux-headers-generic-pae


öncelikle ubuntu için matlab kurulumundaki adımları biraz kendimize yontarak gerçekleştiriyoruz. Dökümanda bahsedildiği gibi gcc-4.3.4 kullanmak şart değil. Sadece adamlar testlerini o sürümde yapmışlar, başımız ağrımasın diyorlar ;)

2. MATLAB a özel bir bin klasörü oluşturalım:

mkdir ~/.matlab/bin

3. gcc ile sistemimizde kurulu(bende 4.5) gcc-4.5 ile via MATLAB a özel bin klasörü arasında sembolik link oluşturalım.

ln -s /usr/bin/gcc-4.3 ~/.matlab/bin/gcc

4.local startup.m dosyası oluşturup, bin dosyasını $PATH değişkenine ekleyelim. böylece her çalışma öncesi bin yolu PATH a yazılmış olur:

printf “setenv(‘PATH’,sprintf(‘/home/%%s/.matlab/bin:%%s’,getenv(‘USER’),getenv(‘PATH’)));\n” >> ~/Documents/MATLAB/startup.m

/usr/local/MATLAB/R2011b/bin klasörüne gidip “mexopts.sh” dosyasını düzenleyelim:

sudo gedit /usr/local/MATLAB/R2011b/bin/mexopts.sh

bu dosyada CC=’gcc’ yi CC=’gcc-4.5′ e, CXX=’g++‘ yi CXX=’g++-4.5′, ve FC=’gfortran’ ı FC=’gfortran-4.5′ olacak şekilde değişikliklerini yapalım. Elbette bunlar bende kurulu olanlar, siz kendinizde olan derleyicilere göre değiştirebilirsiniz.

bu işlemi yaptıktan sonra kaydedip kapatalım. Ardından

sudo /usr/local/MATLAB/R2011b/bin/mex -setup

komutunu çalıştırıp bu ayarları /home klasörü altındaki ayar dosysına yazmasını sağlayalım

derleme sonrası mex şöyle bir sorunla(kısaltılmış) karşılaştı:

libstdc++.so.6: version `GLIBCXX_3.4.14′ not found (required by /usr/lib/libppl_c.so.2)
libstdc++.so.6: version `GLIBCXX_3.4.11′ not found (required by /usr/lib/libppl_c.so.2)

libstdc++.so.6: version `GLIBCXX_3.4.11′ not found (required by /usr/lib/libgmpxx.so.4)

çözümü mevcut libcstd++ kütüphanesine sembolik link oluşturmaktan geçiyor

sudo ln -s /usr/lib/i386-linux-gnu/gcc/i686-linux-gnu/4.5/libstdc++.so /usr/local/MATLAB/R2011b/sys/os/glnx86/libstdc++.so.6

Ubuntu Keyboard Layout diye aradığımızda da genelde OS düzeyinde müdahalelerde bulunmak gerekir(di). Ancak şimdi çok basit bir özellikle bu sorunu halledebiliriz:

1. Setings>Keyboard dan Layout sekmesini açıyoruz 
2. burada Options butonuna tıklıyoruz.
3. Gelen menüden envai çeşit ayarı değiştirebilme seçeneğine sahibiz artık

5. Four-level key with dot butonuna tıklıyoruz

Ubuntu 10.10 Flash Player | Facebook Video Unavailable Solved | Even 64 bit Flash Player Installation Guide | Firefox Chrome Opera Flash Player in Ubuntu 64 bit

After all those Video and Flash player issues in Ubuntu whether Firefox or Google Chrome, I finally got a solution to all of those. The 64 bit Flash Player issue also has the same solution. So let’s get started.

STEP 1 :

64 bit Users

go to Link : http://labs.adobe.com/downloads/flashplayer10_square.html

fron the release list download the one for 64 bit linux extract it get the ‘libflashplayer.so’ file.

32 bit users

go to http://get.adobe.com/flashplayer/ from the ‘select version to download’ drop down menu download the ‘.tar.gz’ file for linux extract it get the ‘libflashplayer.so’ file

STEP 2:

FIREFOX –

a. Open terminal go into the folder/directory where ‘libflashplayer.so’ file is using ‘cd’ (eg. cd Downloads or cd Desktop )command or any other way you like.

After that …..

b. In Terminal type

sudo cp libflashplayer.so /usr/lib/firefox-4.0-4.0b13pre/plugins

Note: Look carefully at bold folder ‘firefox-4.0-4.0b13pre’, this is my installation you can change this to your installation like ‘/usr/lib/firefox-3.6.15pre/plugins’ etc. rest remains same.

GOOGLE CHROME –

a. same as for firefox.

b. In Terminal type

sudo cp libflashplayer.so /opt/google/chrome

OPERA –

a. same as for firefox.

b. sudo cp libflashplayer.so /usr/lib/opera

That’s it Enjoy every video in Firefox, Opera, Chrome in Ubuntu
