Programming :: Displaying The Contents Of Buffers In A Protected And Non-protected Critical Section?
Nov 19, 2010I have this project for my operating systems class and I have put together the basic flow chart to aid me in writing the program. I know how to use pipes as a buffer to hold info. I know how to create a binary semaphore. But what I dont know is this:
How to "use a delay adjustment parameter K in the critical section to adjust the speed of the display process to show that without semaphore protection the displayed contents of the buffer are randomly interleaved."
First off, I am definitely not asking anyone to give me the solution. But I do need some guidance. So I figure there will be an if statement with two options:
1. If true, use semaphore protection to enter/exit critical section
2. If false, no semaphore protection -- this is where the contents of the buffer should be interleaved.
Now does that mean that as each child process enters the non-protected critical section, it should "sleep" for a randomized time? I mean, will this allow my output to be interleaved?
So lets say my command line looks like this:
what happens to the 100? Is it randomized using rand and srand and passed as a parameter to sleep() inside the critcal section?

Mar 22, 2010This is sort of a weird question.'m helping an agency develop a Microsoft Access database. They use windows and I use Fedora. I can run Access in Crossover Office if I don't get too fancy.I've sent what I've done to them for their review and comments and somehow it has become password protected. I've checked the Access settings and their is no password set from Access. I've tried a chmod666 on the file and sent it to him again and he says it is still calling for a password

Nov 30, 2010I created a password-protected .doc file in Windows yesterday using the latest version of OpenOffice (3.2.1)Opening the file worked perfectly; double-clicked the file, OpenOffice popped up and prompted me for the password, then it let me edit the document as usual.Tried it on another computer with Microsoft Word; worked perfectly as wellFor some reason though, it won't work in Ubuntu (10.10). I'll double-click the file, it'll open with OpenOffice and prompt me for the password, but once it opens it's in "Read Only" mode.I tried it on another Windows computer, just to see if it would work, and it did.I right-clicked the .doc file and looked at the permissions: (picture edited for privacy)Every time I tried changing it from "Read-only" to "Read and write" it automatically (and immediately) switched back to "Read-only"

View 2 Replies View RelatedUbuntu :: File-Sync With Unison To A Password-protected Share?
May 11, 2011Been thinking about a new backup-strategy for my family and me. In our house is an Ubuntu Server (10.10) and NAS (Zyxel NSA210). Now I thought I'd create a Cron Tab entry on all machines which will sync specific folders automatically to either the NAS or a specific backup drive in the server. So now the question is: "How do I do that without seriously compromising each family members privacy by making their backed up files available to everyone in the house?" So in essence I'd like to sync/back up the files to a password protected share for each family member. But this process should still be done automatically every few minutes or so without them having to enter any password at all as their specific password is stored locally.

View 3 Replies View RelatedUbuntu :: Any Way To Unlock File Info In Koala?
Jan 8, 2010Is there any way to "unlock" file info in Koala to become visible in the properties of that file? For example, when opening an .mp3 in VLC and checking the information, I am able to see and edit extra info that I do not see when simply right clicking the file and selecting properties. Another example is that GIMP saves comments to images, but I have nowhere to view these comments once they are saved. I would like to see more info when checking the properties of a file, dare I say like Windows enables users to. So is there a terminal code or plugin that I can install?

Apr 1, 2011At work I'm using a windows box with local and network drives. One of drives I have mapped is my Linux home directory (We have separate windows and linux accounts and home directories here). When I view it from windows, all of the files and folders beginning with . are shown, as would be expected. (Although . and .. aren't in any folder)
Just wondering if there is a way to tell windows to not show anything starting with a dot. I was hoping there's a registry entry or something that defines what a 'protected operating system file' is, so I could put dot files in the same category as thumbs.db etc.

Jun 9, 2011I have an 4 GB USB Drive that bugs me. When I insert it, the fallowing device maps are created in /dev.
1: sdb
2: sdb1
3: sr0
The sr0 is registered as an Optical Disk that I can't remove for some reason. I have tried providing sdb with an new empty partition table, but the sr0 partition does not get removed by this. I think it's something created by some Live Linux CD I may have put on the disk at some point. The label is named "U3 System" and it contains the files "LaunchPad.zip" and "LaunchU3.exe".
General :: How To Dd A Copy Protected Disc
Jan 26, 2010I like to make iso backups of my disc. I was going through some game cds that I have not backed up yet. I want to stress I DO OWN THE DISC. I just want to make an iso backup of the disc just in case something happens to them.
I normally use dd to backup my disc to an iso. Typically I use this command
Code:
dd if=/dev/sr0 of=someimagesname.iso bs=2048 count=1234567
I always replace the numbers for count with whatever the volume size is when i run isoinfo -d -i /dev/sr0. However I have a few game cds that I can not back up. I have tried 3 different disk that have this issue. I think they are all copy protected.
I am trying to backup the following disc:
Microsoft Rise of Nations
Sid Meier's Civilization 4 Warlords
Microsoft Empire Earth 3
When I dd any of these disc I get an iso that is 1.7GB and is not a valid iso image.
I was however able to back up other disc. How can I make an iso backup of the copy protected disc?
I would like to stress I do not condone pirating and I understand that some people may think this post is related to piracy. I simply want to make a backup of a disc that I have legally purchased
Security :: Use Protected Password In Script?
Jan 18, 2010I have a bash script that will unencrypt a file, use the unencrypted file for a very short time and then delete the unencrypted file. The problem is that my password is in clear text
[code]...
Obviously this isn't so secure, but I need the script to be non-interactive. How do I hash, encrypt or otherwise make secure the password for the openssl command? I know that the openssl can protect passwords, e.g.:
openssl passwd -crypt "password"
But can I use this protected password in my script?

Jul 31, 2011Each time I try to just open a password protected archive with Ark it just shows a "Loading file" progress bar, but nothing happens after several minutes. And if I just right-click and select "extract" extracts nothing. It doesn't even ask for the password at any moment. I also checked the help typing "man Ark" in the console, but found nothing related to passwords. Has someone successfully opened archives with password with Ark? Or is it still buggy?
And on a side note, I can open normal .rar files, but cannot compress files. It says "failed to locate program RAR in the PATH". I thought Ark was all self-contained. Do I need to install something else?
