dd With Progress Bar 2.0

many of you might remember my first article about this. It was written in 2009 and by the looks of it is somewhat outdated.

What is dd?

dd is an application to make bit for bit copies of a hard drive, or anything else you need a bit for bit copy of. One of dd’s downfalls is that it doesn’t have a progress bar. Instead you are just staring at a blank screen, waiting for dd to finish copying your drive.

We Have a Android in Our Lives

Yes the phone, my wife bought a HTC Aria.  As all of you know I don’t use a smartphone, I don’t even use a cellphone anymore.  As a result of this I couldn’t get to my servers when on the road without a laptop.  With the Aria this all changes, I can now use the wifes phone to connect to the servers when on the road.  As you all know I am notoriously cheap, so we opted for the cheapest mandatory data plan we could get.  We only plan on using the phone on our home network, and reserving the 3G network for emergencies only.

Introduction

You could see this as part 3 in the series: How To Get Atheros AR242x Wireless To Work
It’s with disappointment that I have to report the following:

I started with a fresh install of Kubuntu 8.10, the reason for this is simple I wanted to make sure that nobody could say “you should have done a clean install”. On a clean install out of the box the AR242x doesn’t work.

What I Tried First

So I started to search for solutions. There a several solutions out there here is a quick list:

  • Install linux-backports-modules-intrepid. This works but you would have to reload the driver every time you log on.
  • Blacklist ath_hal and ath_pci. This didn’t work for me. The idea behind this is that the madwifi module will not load and instead ath5k is used.
  • Download and install the new wireless driver which uses the newest version of ath5k.
  • The last option worked the best for me so that is what I’ll go with for this how to. Let me clarify that ath_hal, ath5k and ath9k are all developed by madwifi so props to them for doing such a great job of developing the drivers that make wireless for the AR242x work under Linux.

    cpufreq-set great little tool to change the frequency scalling of the CPU

    If you have a laptop then you already know about frequency scaling. If you ever watched you CPU frequency while you plugged you laptop in to the wall socket. Guidance will pop-up when the laptop is plugged in telling you that you laptop is now in “performance” mode.

    Why do you need CPU scaling?
    Scaling in a laptop is used to conserve battery power when on battery power. How ever on a regular desktop you will find CPU scaling is on as well, why you might ask? On a desktop it’s a noise thing lowering the CPU frequency reduces heat and therefore reduces the fan speed needed to cool the CPU.

    However I happen to like to have my desktop run in “performance” mode all the time, with the case that I have the increase of noise from the CPU fan is hardly noticeable because of the great noise canceling isolation in the case.

    Sound problem fixed.

    As said I have a A205-S5825 Toshiba Laptop, and I was surprised when sound worked out of the box but dmix didn’t. Haven’t been able to find why but today I had some extra time and I finally fixed it.

    Description of the problem:

    Normally ALSA(Advanced Linux Sound Architecture) will install Dmix out of the box and it will work right away in this case for some reason it didn’t. Possibly because of an issue during installation of the OS.
