Like many other users of the brand new MacBook Pro 2011 model I have been experiencing issues with the GPU crashing, graphics freezing up and other stability issues since I first took delivery of my new MBP.
I have also been lucky enough to have the issue that overnight when my computer locks itself for some reason this causes the GPU to crash also therefore when I try to log on in the morning I find that I have to do a hard boot (which interestingly has caused data corruption on an external volume twice now *sigh*).
I digress, I have figured out a bit of a work around when the GPU crashes which I have only tested twice but I would love to hear feedback (please leave a comment here) on if this has worked for you as well.
When the GPU Crashes, ensure you can still turn your caps lock on and off (this will confirm it is a GPU crash and not a full system crash)
If you can turn the caps lock on and off, press the power button once on your Mac Book Pro (do not hold it down, just press it once).
Wait for the system to hibernate/sleep etc
Once the system has powered off, press the power button again
Wait for the system to start back up again
Disconnect an external display if you have one now, or reconnect it if you do not, then the graphics should come back on
Why does this work???? NFI I am new to the Mac Platform so will not even try to explain it. I have only used this to reset the GPU after a crash overnight but I am guessing it will work if you have a GPU crash during normal work as well.
Let us all just hope that Apple Fixes this ASAP.
Vivid Wireless plus MyNetFone VOIP equals affordable phone calls
For those of you that have the Vivid Wireless Home Gateway but have yet to make the plunge into the realm of VOIP or alternatively have the Vivid Wireless VOIP (Voice over Internet Protocol) but would like to change providers as the pricing is not competitive (a.k.a. expensive) this tutorial is for you.
When I first signed up to Vivid Wireless I decided to give their VOIP a go (which happens to be provided by Engin whom I have used before), however while I found the service to be of a good quality, the price per month was exorbitant in comparison to what else I knew was out there. After managing to find on the web what might as well be considered the “real” admin password to the Vivid Wireless Home gateway I was able to “tweak” the settings so that I could use a provider other than Vivid Wireless for my Voice over IP. While I chose to go with MyNetFone (as is described in this tutorial) the steps could be used to guide through the setup any VOIP provider on the Vivid Wireless Home Gateway.
To begin I have this little gem from MyNetFone, if you want some wicked deals head over to https://www.mynetfone.com.au/whirlpool/VoIP/Plans. I am personally using the NeoSaver yearly plan which (at the time of writing) costs less than $60 per year and gives you:
1 Included DID (i.e. local phone number so people can call you)
60 local, national and certain international calls per month included
10c un-timed local and national calls after the included calls
Up to two lines (so yes, in theory you could have both ports activated on the Vivid Wireless gateway although I have not tried this myself).
Now, before I continue below I would like to say that if you proceed you will be unable to get Vivid to support any VOIP problems because obviously when you log in as the Vivid Wireless engineer you are going outside of what was originally intended for the average Joe. If you ever have any problems you can always do a factory reset and get your original settings. I would like to stress however that logging in as the Vivid Wireless engineer you do so ***at your own risk***.
Now on to the fun stuff. After you have signed up with MyNetPhone (or really any other provider to be honest) follow the steps below to set up the VOIP port.
Go to 192.168.1.1 in a web browser and log in with the username “vividwireless” and password “engineer2009″

In the top right hand corner click on the “Networking” icon

In the Sip Server-Registrar Server, SIP Server-Outbound Server and Sup Server-Proxy Server fill out the IP address to be the SIP server of your provider in the case of MyNetFone it would “sip00.mynetfone.com.au” for all three.

Scroll further down the VOIP settings page to where it says “Line 1 Basic Setting”. Change the User Domain, Number and Authentication Name to be the username for your VOIP line (different to your MyNetPhone login check your line activation email for the line username and password, in the case of MyNetFone the username here will be a number like 1234567). Also enter the password for your VOIP line.

Scroll further down the page again to “Line 1 Codec Setting”. If you have good signal strength I recommend starting with G.711 muLaw then G.711 aLaw, then G.729. If you have signal strength issues or a slower connection I would try G.729 as the first option.

Finally click Apply and you are all done, your phone should now register and you should be able to receive incoming calls and make outgoing calls.
***Please Note*** If a firmware update ever happens you will need to re-input these settings again as the firmware updates to the Vivid Wireless Home Gateway will change these settings back to their default.
Let me know how you go or if you have any issues I have the “Contact the Author” button on the top left here so you can chat to me when I am online.
R1Soft is not discovering partitions or file systems
Today I managed to fix an issue that I had been struggling with for quite a few days. I have been running a new VPS which uses Xen and had been struggling with getting R1Soft to detect the filesystems. The R1Soft client was detecting the partitions however was not picking up the filesystems on the partitions.
After quite literally a week of searching and hunting I found the answer on R1Soft’s site and it has to do with a quirk of the way Xen works. If you find you have run into this issue pop over to “Running the CDP Agent on Xen” and you should be right as rain in no time.
