Can I have two different operating systems (BIOS and UEFI) on two different hard drives? I have windows 7 installed on my hard drive (installed it in BIOS mode not UEFI), and I want to buy another hard drive and install ubuntu 16.04 on it through UEFI. When I have both hard drives connected to my motherboard will I be able to choose which OS to boot into when I turn on my computer or would I have to always go into my BIOS and change the boot order?  I was thinking of just installing ubuntu 16.04 on my current hard drive alongside dual boot but I don't know if I can install it in BIOS mode instead of UEFI?
How do I install Ubuntu alongside a pre-installed Windows with UEFI? I'm absolutely new to Linux. I would like to know how to install Ubuntu alongside the pre-installed Windows 8+ OS.  Should I do it with Wubi, or through the Live USB/DVD?  What steps do I need to take to correctly install Ubuntu?
Correct tracked camera orientation I have been playing around with camera tracking and I'm happy enough with the tracking and alignment of the markers with the footage when viewed through the camera.    The problem is, when I am not looking through the camera I can see that the grid isn't aligned to the camera.    How do you correctly align the grid to this tracked camera? I have set a floor and two points for scale, also clicked setup tracking scene, but this just added cube and plane which were on the grid. when is f@g not the same as f[g]? Is there any hint that some of the beings in Tolkien's lore may have survived into "our" times? In Tolkien's lore, they are many very old beings. Is there any indication that some or even one would have been truly immortal and survived into what we would call "our" history or Age? Galadriel, Cirdan, Ingwe, Bombadil, Ungoliant, or any Maia or Ainur? Anyone or anything? Seems there must be some kind of carry-over seeing as how "man" existed in this time. How to copy files into /usr/local/? (permission denied) I'm still a little new to Ubuntu and was wondering how I can copy files, in this case Aptana Studio, to /usr/local/ without being denied.   Is there a way to do it in terminal? Or a way to allow myself permission?  I should add that I am using 10.10 Desktop edition, not server. Biasing circuit - Voltage follower circuit I am using , which is and Bias controller/sequencer. I am using this for Providing gate voltage and drain voltage to the . In the datasheet, it is mentioned that the module with combination of EVM can be used in two applications. Application Option 1: Fixed negative gate biasing with pulsed drain biasing. Application Option 2: Pulsed negative gate biasing with pulsed drain biasing. I am trying to design both applications on a single board. The second option for future use. For the 1st application option, he has mentioned a few pins as No connection and he has used those NC pins on the 2nd application.  The issue I am facing:- They have used voltage followers for providing a low impedance output path for pin number 3(GCO). I have reverse-engineered the Ckt from the below-attached image, but I am unable to identify the voltage follower they have used. Pin number 2 of the voltage follower has been connected to pin number 2 (NC/GCP) of the Module. There has been no description of this pin number. I am guessing these:-  Pin numbers 1 and 4 are connected together and output is provided through them. Pin number 5 is +Ve supply hence connected to GND(Highest +Ve supply)? Pin number 3 is connected to -8V Pin number 2 is connected to pin number 2 of MABC-001000-DP000L, which I am unable to understand.  I have mailed component manufacturer regarding full schematic, till now I haven't heard from them. Can anybody help me with this? Thanks in Advance. Low-resolution pic of EVM. I don't think it helps in any way.   Layout Image I am working on an iGoogle-like application. Content from other applications (on other domains) is shown using iframes.

In the 3rd and 4th editions of D&amp;D, there were explicit rules for determining if a character knew anything about a monster before them.  In 3rd edition, for example, use of the  skill with a general DC of 10 + the monster's HD allowed for determining one fact, plus one fact per 5 points over the check.  Looking at the Intelligence section of the 5e PHB, I don't see any similar notation.  Does 5e provide any guidance as to when a player could use their out-of-game knowledge about a monster, or when the player might be told things their character would probably know in-game? Database Encryption scan for database  was aborted. Reissue ALTER DB to resume the scan Showing that $Q_n=D_n+D_{n-1}$ Let $T_n$ be the set of permutations of $\{1,2,\ldots,n\}$ which do not have $i$ immediately followed by $i+1$ for $1\le i\le n-1$; in other words, let \begin{align} T_n=\{\sigma \in S_n: \sigma(i)+1\ne\sigma(i+1) \text{ for all } 1\le i\le n-1\} . \end{align} Let $Q_n$ be the number of elements of $T_n$.    Let $D_n$ be the number of  of $\{1,2,\ldots,n\}$.  It is not hard to show algebraically that $Q_n=D_n+D_{n-1}$, but I am having difficulty coming up with a combinatorial argument to show why this is true.  (I believe there are $D_{n-1}$ elements of $T_n$ that leave $n$ fixed, and $D_n$ elements of $T_n$ that move $n$, but I don't know how to justify this combinatorially.) How to show TCP listenings and filter them by local IP on Windows? Server has numerous IP addresses, set up on it's network interface.

It should be mandatory for everyone asking questions on the Internet to read , which says:     Help your community learn from the question. When you field a good question, ask yourself "How would the relevant documentation or FAQ have to change so that nobody has to answer this again?" In the course of creating the content for a site, we've ended up with orphaned content nodes that are not linked to from anywhere. I'd like to find and examine these. Surprisingly, I can't find a module for this.  Tiny hypothetical example: I'm building a brochureware site. Someone wrote a "Contact" page, someone else wrote an "About Us", and someone else wrote "Directions". The person writing "Directions" forgot to put it in a menu link or add a link from "About Us" to "Directions". So "Directions" is orphaned: there are no links to it. I'd like to find all such nodes so I can figure out what to do with them. Mark or don't mark required fields if all are required? If all fields in a form are required should they be marked somehow (eg. with an asterisk)?  I see this done a lot and find it redundant?  There could be a difference in big forms and small forms, but in big ones I would add a note at the top that all fields are required, but I wouldn't necessarily do that on small ones.  What do you think is the right approach? I have a large mesh with > 1.5 million faces. I would like to uniformly add a texture to the object without UV mapping (as blender freezes every time). The texture is quite simple and can be applied evenly throughout the object. Why does the Community user have votes cast?

I have been currently learning Drupal while trying to duplicate a Drupal application into CakePHP.  I have been looking at the  database tables to know where data is being stored so I can safely migrate any data or study how it is working.  I have researched and have come across questions like:     So far, I have only seen the title in my Drupal (7) installation.  What I have seen in my node revisions table for a recipe content type, which includes fields like, field_ingredients, field_instructions, field_description, field_preptime, field_cookingtime, just the title of the recipe. This is a sample record on my node_revision table.  nid   |  vid  |  title         |  log   | timestamp  | status | comment | promote  | sticky ------------------------------------------------------------------------------------------- 1     |  1    |  Awesome Sauce |        | 1369998600 | 1      | 2       | 1        | 0   As you can see I can only see the title.
