How can I change the first byte of multiple files in Linux? Willing to use perl/awk/sed/whatever. Must work correctly on binary files (i.e. not change any other bytes).
I know that this laptop (Asus UL30A) does support playing HD material with the help of the GPU on windows. The question is how can I do this under linux? The CPU load as is implies that this is not activated. I assume that it's limited to a handful of codecs. But which player supports this, if its even supported at all?
I am primarily a programmer developing on windows based OS using c# as my primary language. I am evaluating Ubuntu Linux as an alternate platform and would like to know the best stack for doing web development on this.
I had gone through the following thread Moving development from Windows to Linux but it doesn't answer my questions fully.
Some of the points I am interested are outlined below
PHP/Ruby/Python (What would you recommend?)
Is Mono mature enough for any large scale development? Has anyone any real experience using Mono.
IDE (including debugging support, intellisense, source control integration,Unit testing)
Unit testing framework based on the language recommended
Web framework if any.
Load Testing tools
Web server (I know there are many webservers, but would like to know which one is primarily used by most people)
Your inputs is greatly appreciated.
Thanks.
How do I block a user from accessing the internet under Linux?
I'm trying the following:
iptables -A OUTPUT -p tcp --dport 80,443 -m owner --uid-owner $USERNAME -j DROP
Is that the right syntax or command?
How can I passively monitor the packet loss on TCP connections to/from my machine?
Basically, I'd like a tool that sits in the background and watches TCP ack/nak/re-transmits to generate a report on which peer IP addresses "seem" to be experiencing heavy loss.
Most questions like this that I find of SF suggest using tools like iperf. But, I need to monitor connections to/from a real application on my machine.
Is this data just sitting there in the Linux TCP stack?

I am a relative beginner when it comes to choosing web servers and hosting plans. I'm about to signup for a hosting plan with GoDaddy. My main requirement is ColdFusion and MySQL. The plans on offer include Linux and Windows based plans.
Which one should I choose, and why? I don't have a lot of requirements other than what I mentioned above. I never used Linux before but I doubt I'll ever need to do anything beyond tampering with my account.
What are the main advantages of one over the other?
Hello,
I posted this over at stack overflow, but had a suggestion to post it here for better help. Currently, I am running Mint Linux (Release 9). I need to downgrade Java from version 1.6 to 1.5, and have been trying to figure out how to go about this. So far, I've had no luck. The package manager doesn't seem to have it.
Does anyone have any suggestions?
Thanks,
- Chris
I'm looking for a replacement for hnb, which served me well but seems to be abandoned.
Please do not suggest text-editor based approaches like emacs org mode or vim outliner.
I want a stand-alone tool, preferably written in Python, with ncurses interface (so it could run on Linux with no X server).

Is there any software or utility for this purpose.
