With Juju on windows 8 I get the following error:  Cannot parse: C:\Users\user\AppData\Roaming\Juju|enviornments.yaml\YAML error : line 126: did not find expected hexadecimal number   It seems that it does not like my subscription id that I created with a new azure account.  Any ideas on how to fix this? It is a legitimate subscription id...
I am trying to get Juju working on Windows 8 but I am running in to some errors when trying to get juju to see my ssh keys:  C:\Users\username&gt; juju bootstrap error: error parsing environment "azure":     read C:\Users\user\SkyDrive\Documents\Azure\ssh\: The handle is invalid.   I've added a public key I generated with putty to the directory above called azure  My environments.yaml file has this in it:  authorized-keys-path: C:\Users\user\SkyDrive\Documents\Azure\ssh\   Any ideas?
We've got a Windows 10 installation running in an environment where it can occasionally lose power and restart. However, this sometimes leads to corruption of files.  I've had a look at Windows "To-Go" but this seems to be persistent. And I've also checked out virtualisation, but that would require us to run a non-persistent Windows 10, in another Windows 10 environment.  Is it possible to install Windows 10 as a "non-persistent live CD"? So that a user will have a seemingly fresh Windows 10, but doesn't require to re-install it at each startup?

In this case 15. I have 2 quartz crystal resonators in my pcb board: 32.768 kHz &amp; 20 MHz. They are connected to a Freescale MC12311 transceiver IC, which has an HCS08 micro-controller embedded in it. I want to test if these crystals are working properly or not.  Available tools: Oscilloscope, Frequency-Meter (Digital Counter), Digital Multimeter.  How should I use these tools to test the crystals in board?   Note: The capacitive load-effect of probes should probably be considered. If not, the measurement would not be accurate, or even worse, the crystals would not work at all.     Edit1: I used both the oscilloscope and the frequency-meter (with x10 probes), but unfortunately there was nothing monitored at all. What is Change Detection and performing such analysis with open source tools? I was given a laptop with a totally dead display. I do not want to pay to replace the broken display, but I would like to use the laptop as a server and connect to it via SSH to control it.  I have pulled out the internal hard drive from the broken laptop, and I want to install Debian GNU/Linux and the SSH server onto this HDD using a working Debian laptop.  However, the hardware in the two laptops is very different, and I am wondering what kind of problems I would run into when I plugged the drive back in to the laptop with the broken display because of this?  How would I make this work? What is the proper way for me to install a bootable copy of Linux onto a HDD that will be used by a computer with different hardware? I was running my OS off a USB stick fine and the wifi was working. I installed it to my SSD and setup again but not the WIFI adaptor isn't working.  I followed the first time  and it worked but since installing onto the SSD and doing the same its not working.

Electrical Machines based on Electric Fields Our teacher asked us this question during the lecture for Power Electromagnetics. We know that Electric Fields and Magnetic Fields are easily transformable into one another. And they are used greatly in various systems.   He asked us why is it that almost all the electric machines are still based on exchange of magnetic energy? Why isn't electric field used for power exchange and interaction through air gaps for a machine? Need help in proving that $\frac{\sin\theta - \cos\theta + 1}{\sin\theta + \cos\theta - 1} = \frac 1{\sec\theta - \tan\theta}$ We need to prove that $$\dfrac{\sin\theta - \cos\theta + 1}{\sin\theta + \cos\theta - 1} = \frac 1{\sec\theta - \tan\theta}$$  I have tried and it gets confusing.

Please refer to  of our .  Skype 4.3 is just released with considerable improvements. As a regular Skype user I want to use the latest Skype on my Ubuntu 14.04, but there is no updates from Update Manager. Even in Skype website only Skype 4.3 is available only for Ubuntu 12.04. Is there anyway to use this latest Skype on Ubuntu 14.04 or how much we have to wait for the update? I ask this Question on behalf of my neighbor.   Their 12 year old son saw his parents having sex.

What does the term "Extended Partition" mean? Is it safe to use this type of partition? In the image below, what does Extended 103 GB mean? Would someone give a thorough explanation of 1.14 Minecraft's /data modify? Okay, so I've been searching all over the internet for an explanation of data modify ever since I heard Sethbling passively mention it in one of his videos. The only  thing I could find on it was the wiki and the update log for the 1.14 snapshot. So, I checked these, and they hardly explained it at all. I can get /data modify block 123 20 123... and that's as far as I get.  Minecraft wiki does not at all define clearly what  is (the thing meant to go after coords), nor does it specify what each operation does to what. Operations include (without explanation, and excluding set (which it does explain)): append, insert, merge, and prepend. Then, it has from|value as the next option, which aren't explained either. After this, it just has block/entity and coords/id. So, I know the format (mostly), but I haven't the slightest idea what any of it means. And nothing I've seen on the internet even mentions the command save for Minecraft wiki itself.  Please explain if you know what data modify is. Thanks!
