Ubuntu :: GIF / ZIP Embedded File - Grafting In Hex Editor?
Dec 24, 2010
Gif 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.

i recently updated a machine from 4.5 to 4.6 Factory and the Embedded Text Editor function for editing text files inside Konqueror seems to be broken (viewing file is fine, but no editing). Doing research i found that it had been reported, but ignored as an "opensuse problem": Bug 259338 - I cannot edit text files when I preview them in konqueror by using "Embedded Advanced Text Editor" which is not a case in 4.5 seems like i remember that it was a kate plugin or katepart functionality, but others would know more.it was apparently reported in the RC days and disregarded, perhaps someone has more info about it?it doesn't seem to be a config file problem since a new user is in the same boat.for me it is oft-used and would be sorely missed.

Everytime I open Konqueror, it opens in "Embedded Text Editor" mode . So if I open it then click on a bookmark, it opens in edit mode. I can select View->View Mode->khtml and then the page displays properly. If I click on a link from that page, it displays properly. If I open a new tab, it is back to edit mode. If I open konqueror from konsole, it has the same behavior. I have removed all files under ~/.kde that mention konqueror, kong_* or kfmclient.
I checked the menu entry for Konqueror, and it is "kfmclient openProfile web browsing". I have set the view mode properly, then manually saved the profile in Konqueror. I have checked the system settings file associations, and the konqueror entry has the same application command (kfmclient) as the kde menu entry. Does anyone know how to make the view mode "stick" for Konqueror such that when clicking on html urls or selecting bookmarks causes Konqueror to display properly?

I 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()?

On windows I really only used Notepad++ as my text editor, it had two features that I loved.What I need to accomplish is what I would do with Notepad++ column editor.I could have like 100 lines, and place the cursor at a column, and goto edit>column editor, and I could insert an incrementing number. (I could also pad the incrementing number with 0s, this was GREAT for making batch files among other things.)So each line at that column had a number higher than the previous line.The other feature that I used sometimes was a search/replace with regex patterns.Does anyone know of an editor that has those features for linux? I am mostly after the column editor insert feature but if you know of one with both features that would rock.

After installing skype from rpm I wanted to add a skype repo for future updates. As root I did 'touch skype.repo' and tried to open by 'kwrite skype.repo' but get the undermentioned error.

I am having trouble getting a certain program to work. It's called Magic Set Editor and it has a linux version. It seems to install fine, but when I press the link to run the program it always says there is no file type associated with this program. Here is the site to download it: [URL]. I've tried the full and reduced versions, and I tried building it from source, which I have no idea how to do. I am using Fedora 10. Also, I've gone to their linux guy and he tried to help, but has never used Fedora, and so nothing he said worked.

I wanted to know how can I cross compile SMS SERVER TOOL for an embedded computer and make just one binary file for it or how can I change all of its default files places like its demon and object file and gather all of them to one directory to execute and use and run.let me explain it better for you : I have an embedded computer with Linux OS that its file system is read only and I can not add any file to /usr /lib and ..... and I can just mount a SD memory card to it and copy all of my programs to it and run them from there as you understand I have two choices to choose, first make one big binary file for each program that I am doing it now and it is not a suitable solution and the second is finding the way to change default place of shared object file of my program.now you tell me what can I do to solving this problem.

I am using Ubuntu and looking for a good editor to edit a file that is > 4GB. I just need to put content at the end and beginning of the file. I suppose I could use something like
cat "text to add" >> huge_file
To append to the file. Is that the route to go? What about prepending? In general, what is the best route if I wanted to edit somewhere in the middle?
I've tried VIM and it fails miserably. I assume emacs and nano would be even worse. What else is there? I assume to accomplish what I am looking for, the editor would have to be specifically designed for this by not keeping the entirety of the file's contents in memory.

I'm looking for a way to remove embedded features from a PDF document. I recently purchased a Kindle DX. When I try to open some of my PDF files on the device, I get a message saying: this pdf cannot be opened due to embedded features not yet supported by kindleI'm looking for a way to remove the use of these features from the document so I can view it on my Kindle. I'm a Ubuntu Linux user. (I tried opening the PDF in Document Viewer and printing it to a PDF file by going to File->Print. This make it so I could open it on the Kindle DX, but the font is messed up and very difficult to read. This won't do.)

It seems that watching an embedded video crashes my system every once in a while. Is there any way to figure out what is causing the crashes or fix it?
Some extra info - The cpu usage jumps to 45-50 percent when a embedded video is playing.

I am preparing a poster using draw and impress. Everything go well till I save the file and quit the impress. When I open the previous prepared poster in impress, none of pictures embedded retrieved. I have also prepared a diagram using draw. There is no problem importing it into impress. The problem comes when I close the poster and re-open it in impress. It goes crazy. 1.png is before closing the impress and 2.png is after re-opening it.

I recently acquired a few japanese anime which have English subtitles. All the videos are in .mp4 format. They have embedded subtitles (though not hardsubbed, since I can turn them off). My question is how do I edit and re-embed these subtitles, since the translations are less-than-perfect?
