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).
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 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 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?
In linux version of firefox (specifically in my case Debian's rebranded Iceweasel), folders of bookmarks in the personal toolbar show a little down arrow on the right of the name. It serves no real purpouse and just takes up horizontal space, is there a way to remove it?
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).

Hi,
My MacBook's HD started failing recently. Fortunately most of the data was properly backed up and most of the other important data could be retrieved by hooking up the drive with the help of an external USB enclosure, but the problem is that my home directory has been encrypted with FileVault and I currently don't have easy access to a Mac.
So can the FileVault sparsebundle be somehow decrypted and read with Linux?
