  • Snow Leopard 10.6.3 Freezes Frequently

    - by Abhishek
    Snow Leopard 10.6.3 on my Macbook Pro freezes quite frequently now. It freezes for few seconds and then works fine. During that time trackpad does not work and keyboard works partially (missing keystrokes while I type). Initially it was once or twice in a day but now it has become quite frequent. Is somebody else facing similar issue?

    Hi All, I have created a table called table1 and it has 4 columns named Name,ID,Description and Date. I have created them like Name varchar(50) null, ID int null,Description varchar(50) null, Date datetime null I have inserted a record into the table1 having ID and Description values. So Now my table1 looks like this: Name ID Description Date Null 1 First Null One of them asked me to modify the table such a way that The columns Name and Date should have Null values instead of Text Null. I don't know what is the difference between those I mean can anyone explain me the difference between these select statements: SELECT * FROM TABLE1 WHERE NAME IS NULL SELECT * FROM TABLE1 WHERE NAME = 'NULL' SELECT * FROM TABLE1 WHERE NAME = ' ' Can anyone explain me?

    - by user308368
    Hello. I have an executable (PE) file that load a dll file as represented in the Import table... let say: PEFile.exe Modules.dll my question is how can i remove Modules.dll's import_descriptor from the imports and do its work by loadLibrary without the rely on the import table and without destroy the file???... My bigger problem his i could not understand exactly how the Import thing works... after the loader read the information he needs to do the import's thing, i believe he use the LoadLibrary, GetProcAddress APIs... but i couldn't understated what he doing with the pointers he get... he putting them somewhere in memory... and then what just call them?!? all the papers i found in the net explain the structure of the import table, but i didn't found a paper that explain how it is really work and get used... i hope you cold understand my Gibberish English...

  • Virtual Machine for software renting service

    - by Vilis
    I am currently trying to figure out which solution would be best for software renting service (with proper licensing and stuff). I know its kinda stupid and so on, but I just have to develop it. Long story short - user can connect to a virtual machine (with windows guest os) using vnc and use some specific software for some specific time (eg., 1 hour). I have already considered VirtualBox, Xen and some other, but maybe somebody has a better idea. Thanks.

  • If I use a proxy server, can my computer bypass the ISP?

    - by Torpido
    If somebody is using some kind of proxy server to connect to the internet, does their computer connects to the ISP first and then to the proxy server, or does it connect to the proxy server first and then to the ISP? Some of my friends are able to get free internet on their mobile using some Proxy servers. I am not asking you for free internet, I am only asking you how this would be possible. How are they are able to trick the ISP firewall?

  • Are the atomic builtins provided by gcc actually translated into the example code, or is that just f

    - by Jared P
    So I was reading http://gcc.gnu.org/onlinedocs/gcc-4.1.0/gcc/Atomic-Builtins.html, and came across this: type __sync_and_and_fetch (type *ptr, type value, ...) type __sync_xor_and_fetch (type *ptr, type value, ...) type __sync_nand_and_fetch (type *ptr, type value, ...) These builtins perform the operation suggested by the name, and return the new value. That is, { *ptr op= value; return *ptr; } { *ptr = ~*ptr & value; return *ptr; } // nand Is this code literal? or is it just to explain what gcc is doing atomically using c-like syntax? And if this is the direct translation, can someone explain how it is atomic?

  • Does Windows 7 deleted files generated during hibernation?

    - by Koffeehaus
    Somebody was using my Windows 7 and she hibernated it instead of shutting down. Later, I booted up Ubuntu and moved about 2GB worth of files from the Ubuntu partition to the Windows partition. After booting up Windows (from hibernation), I couldn't find any of the files. Then I restarted the PC, and the files showed for a second or two and then disappeared. Did Windows delete all the files I put on it while it was hibernating?
