What skills or concepts would you include in these three areas of Perl?
Perl Automation Test
Perl Development
Network Scripts / Programming
Could you make it look like a course contents so that I can check out those topics for the above three broad subjects of Perl?
how do you include a string variable as part of a regex in Perl?
View 5 Replies View RelatedI currently run Ubuntu 10.04 alongside Vista. I have been looking for a few linux projects to help me learn, the two that I have thought of have been:
1. LFS
2. Something security related
As for no.2, I am interested in learning about network security, intrusion detection, system logging, firewall logging etc. And as a project I would like to work on creating a desktop box as secure as possible, then maybe testing my own box on my home network.
1. Is there a good linux distro that is designed for security?I know people often say "the distro doesn't matter, it only matters how you configure it.
2. Does everyone agree with this? As far as security, learning, etc, are all distros created equally?
We are looking for a web based, server application to manage staff skills running on ubuntu (10.04 lts). Something like we attach tags with skills to people photographs, and then when people connect to the application by means of a browser, they see a list of tags, they click on a tag they get a list of people who have that skill. Ideally, the tags should be hierarchical (for example, skill: statistics, subskill: non-linear).
View 10 Replies View Relatedi have written some really basic loadable kernel modules. There are a couple of concepts that i'll like to get cleared.
In a tutorial, the Makefile was given as follows-
obj-m += try.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
I understand that -C option of 'make' changes the current directory to /lib/modules/$(shell uname -r)/build (which depends on my kernel).
Now, my question is why to change to that particular directory? Also M=$(PWD) will hold the dir where i have written the module. Why is it required? What does 'modules' at the end of that line indicate?
Q2> We need to include <linux/module.h> and <linux/kernel.h> in a module. If i am right, the module uses kernel headers for these definitions. But how does 'make' find these definitions.
Q3> We are planning to write a custom scheduler for linux kernel. cat /sys/block/sda/queue/scheduler gives us the currently loaded schedulers. How do we expose our scheduler to linux kernel so that we can use it by switching to it.

View 2 Replies View RelatedI'm relatively young and equally ignorant as to C or C++ (or any other language for that matter). I've started learning C, but come across a view that C is getting old/obsolete, etc. and If someone just starts out they should start with C++.
I know that most of the linux kernel is written in C and so are a lot of linux tools. Are there any other areas where C still prevails?The reason I'm asking is that I'm now not sure which one to learn. I know that you'll answer: depends what you want to do. The problem is that I don't really know what one can do with C, as opposed to C++.
I have a small problem with Perl and Apache.
If I use "#!/usr/bin/perl" in the beginning of a perl script the script won't work if the script is at all complicated. Simple scripts like "Hello World" works.
But if I use "#!/usr/bin/perl -w" in the beginning all scripts work?
If I don't use the -w this is whats in the logs:
(2)No such file or directory: exec of '/home/test.net/html/cgi-bin/uh/meny.pl' failed
Premature end of script headers: meny.pl
When I use the -w in the script the error-log shows me this.
meny.pl: Name "main::http_path_cgi" used only once: possible typo at /home/test.net/html/cgi-bin/uh/meny.pl line 24.
I upgraded from 9.10 to 10.04 and now the colors are off. I tried different themes which made some of the tabs more readable, but I don't see how to fix it. Things like background colors in Firefox are too light to see. The same for the grid lines in OpenOffice.org Spreadsheets. Form fields are not outlined. If you don't know where they are you have to hunt by dragging the pointer over the area.
Images look OK.
Does this sound like something others have seen?
I've been using Ubuntu consistently for about three days now. I really, really love the interface and how everything works and all that, but I've been having a couple of weird problems with speed.
Graphics things seem to work really well. When I go into the overview of all my workspaces, it's instant and looks great. The problem is when I open and use some applications.
For example, when I open up the software center, it takes longer than it did the first time to start up. Also, when I drag windows off from being maximized, it takes literally about five seconds for it to show up as being dragged around by my mouse.
When I look at the system monitor, about 20% of my CPU cores are constantly being used. That's 20% each. I have a 3-core CPU, could that be the problem?
Another example: when I went to ..... just now, it would take a second for any volume changes in the video to register.
And I also have smooth scrolling in firefox, but it's very unresponsive now. It's slow as all hell. Even notifications are showing up more slowly.
So, what's the deal? What could I have done wrong?
CPU: AMD Phenom II X3 2.8Ghz
GPU: ATI Radeon HD 4860 1gb
RAM: 4gb
One more thing: I have really bad screen tearing when I try to move windows around, as if there isn't any vsync on. Where can I turn it on or fix this?
I'm still pretty new to Ubuntu and Linux, but I'm an advanced computer user. Since I feel linux is killing my CPU I think I'm going to boot back into Windows 7 for now, but if I can fix this problem I think I want to keep Ubuntu as my main OS after this, having Windows for games, unless I can get Wine to work right with them.
I know this is Ubuntu forums, but my other laptop has Ubuntu and I know this is a community full of very smart people (got Ubuntu help the other day).Anyway , this laptop's problem is, the screen goes teal i areas that were once white. Now, originally I thought something was broken, but now my theory is it's a loose connection. On the bottom left of the screen there is a thick black cable that leads up behind the screen and connects with that duct tape looking thing. If I simply lift up on the black cable, the screen goes back to normal.

View 2 Replies View RelatedWhen I installed a new copy of my distro on another partition, in order to preserve all the settings from my old my user account, I made a user account with the same name on the new installation, and then copied my old user account's files (in their entirety) to the new user account, overwriting it. I did the copying from the root account (where else? I assume the new user account can't overwrite itself while it's open), and root became the owner of everything I copied, making it impossible to open the new user account. So I then chowned the new user account's folder to myself. I still can't get in, because apparently, chown only chowned the top folder, leaving all subdirectories owned by root. How do I make chown include all subdirectories? I scanned the man page, but didn't see a parameter.

View 7 Replies View RelatedI have a CMS I have developed, which will run on several sites all hosted in sub directories on my dedicated server. I want to create symlinks for the main files of the CMS, including all config files, functions and admin sections. Then there will be a few files specific to each site.I read some tutorials on creating symlinks, although most are not very good in my opinion.
Do you have to create a symlink for every file I want to include? Or can I just create a symlink to a directory? For example:CMS is located at /www/cms/.Can I make www/domain1/ point to that directory, and if so, will all files include themselves correctly. I think I am a bit confused on how this works.
