Programming :: Saving File Data Using Python In An Embedded System In An Safe And Fast Way?
Apr 19, 2011I am developing a program in a system where the Linux does not take care of the sync command automatically. So I have to run it from my application always I save some data in the disk, which in my case is a 2GB sdcard. It is true that I can make the operation system takes care of the syncronization, using a proper mount option, but in this case the programm's performance drops drastically. In particular I use the shelve module from Python to save data that comes from a socket/TCP connection and I have to deal with the potencial risk of the system being turned off suddenly Initially I wrote something like that to save data using shelve:
Code:
def saveData(vo)
fd = shelve.open( 'fileName' , 'c')
fd[ key ] = vo
fd.close()
os.system("sync")
But that takes too much time to save the data. Note that I use the sync from the OS every time I close a file to prevent data corruption in the case of the "computer" being turned off with data even in the buffer. To improve the performance I made something like that:
Code:
def saveListData( list )
fd = shelve.open('file_name', 'c')
for itemVo in list:
fd[itemVo.key] = itemVo
fd.close()
os.system("sync")
Thus, first I saved an amount of objects in a list then I open the file and save the objects. In this way I have to open the file just one time to save a lot of objects.However I would like to know if adding a lot of objects before closing the file would increase the risk of data corruption.I known that turning off the system after fd.close() and before os.sync may cause problems. But what about turning off the system after
Code:
fd = shelve.open('file_name', 'c')
but before fd.close()?

Dec 16, 2009my partitioning layout was as follows
Vista Recovery
Windows 7
GRUB
Extended
-->Fedora 12 (ext4)
so, I shrunk my recovery in Windows 7 successfully, and booted into my Fedora 12 live cd to run Gparted, and move the partitions so that the free space could go towards fedora, I did such, and then I couldn't expand the partition to my dismay. Next, I woke up this morning, tried to boot to fedora to run SSH, grub loaded, but when I tried to boot fedora, I got the "File system check failed" error, and when I tried 7, it just went to a blank screen with a single "_" in the top left-hand corner.
General :: Export Display From A Terminal To A Windows PC?
Aug 20, 2011Exporting display from a Linux terminal to a Linux desktop is easy; you do the following:
On 192.168.90.121 (localPC):
xhost + 192.168.10.164
On 192.168.10.164 (remotePC):
export DISPLAY=192.168.90.121:0.0 <br/>
firefox
The Firefox window appears on my localPC. In the above case both PCs are Linux.
Can I similarly export the Linux display to a Windows PC? In the above example, localPC would be Windows and remotePC would be Linux.

Dec 24, 2010Gif files display their length at the start of the file, and zip files have a table with the locations of the files at the end of the file. By combining the two it's possible to create a gif file which, when opened in an archive manager, contains hidden files. How would I go about doing this? Do I have to learn the zip standard and manually graft the files together in a hex editor?
Code:
cat input.jpg input.zip > output.jpg
The zip table must show the file location as an offset to the central directory.

Anyways, below is output from fdisk -l. why does windows see only 75GB of a partition that is 500GB in linux?

Apr 19, 2011I am working on a project but it consist of a large amount of numbers. I have tried using OpenOffice to produce this list of numbers but it keeps crashing when I reach a certain point. So I was looking for some help. I need to see if someone could either help me with using a script or program to export these numbers into a .txt file or if someone could just make the list for me.
I am looking for a text file that will have the numbers 1000000000 to 9999999999 in order. I understand this is a large amount of numbers but this something I don't have the time to just do manually and each time I try to do it with OpenOffice it crashes around 1009000001. Oh and I need the text file to look like this:
1000000000

Debian Programming :: HTML Export - Consolidate Several Lines Of CSV File With Firewall Rules
Oct 11, 2013I have a CSV file, which I created using an HTML export from a Check Point firewall policy. Each rule is represented as several lines, in some cases. That occurs when a rule has several address sources, destinations or services.
I need the output to have each rule described in only one line. It's easy to distinguish when each rule begins. In the first column, there's the rule ID, which is a number.
Here's an example. In green are marked the strings that should be moved:
See example. The strings that should be moved are in bold:
NO.;NAME;SOURCE;DESTINATION;SERVICE;ACTION;
1;;fwgcluster;mcast_vrrp;vrrp;accept;
;;;;igmp;;
2;Testing;fwgcluster;fwgcluster;FireWall;accept;
;;fwmgmpe;fwmgmpe;ssh;;
;;fwmgm;fwmgm;;;
What I need ,explained in pseudo code, is this:
Read the first column of the next line. If there's a number:
Evaluate the first column of the next line. If there's no number there, concatenate (separating with a comma) the strings in the columns of this line with the last one and eliminate the text in the current one
The output should be something like this. The strings in bold are the ones that were moved:
NO.;NAME;SOURCE;DESTINATION;SERVICE;ACTION;
1;;fwgcluster;mcast_vrrp;vrrp-igmp;accept;
;;;;;;
2;Testing;fwgcluster-fwmgmpe-fwmgm;fwgcluster-fwmgmpe-fwmgm;FireWall-ssh;accept;
;;;;;;
The empty lines are there only to be more clear, I don't actually need them.
CentOS 5 :: Mounting Windows File System?
Jun 2, 2009I have a dual boot system (CentOS and Windows XP Pro). The computer has 2 disks with the operating systems on sda. My data files are on the 2nd disk (sdb I think). I would like to be able to access the data files on sdb from CentOS. I tried issuing the Linux command:mount -oro -t ntfs /dev/sdb1 /mnt/winbut CentOS tells me that ntfs is not a file system it recognizes. Even if I leave out the -t ntfs I get the same message. Any ideas on how I can get access to the Windows files while in the CentOS boot?. I got the idea for the above mount command from the book: Fedora 10 and Red Hat Enterprise Linux Bible byCristopher Negus.
