I am currently using Sheep It! to render my blend (built on v2.68c) on multiple computers, and I noticed something rather strange. According to the log on-site, the frames rendered from other people's blends were completing in 3 to 4 minutes. This was on an 4 core i5. My main rig (with an 8 core i7) was completing frames in no less than half an hour. How is this possible?  To clarify, these people's frames are very complex, often with very detailed textures. I have 2 objects in my blend. Below are the options I changed for my blend:   Aspect Ratio: 1000px x 1000px Output: PNG Clamp Indirect: 0.98 Render Sampling: 128 Min Light Bounces: 0 Max Light Bounces: 4 Cycles Render   Is there something in there that I should change to make it go faster? I can't really comprehend how it's going to quickly.  EDIT: To answer what @Duarte asked...   System Specs: i7-920, 3GB DDR3, GT 630, Windows 10 I have two circles, extended to form a sort of coin with a star on it. It is not complex at all. I have Firefox and Steam running in the background, but not actively. I've been away from the computer for 8 hours and noticed this behavior. (I am running Blender from Steam.) I made sure when I began rendering that the blend was set for CPU rendering.          And to answer what @pycoder asked, yes, I am using Cycles Render.
So I'm at that step where I am finally ready to Render my first big project. Aaaaaand it's been stuck on the first 4 tiles for the last 2 hours?   I am using a MacBook Pro Processor: 2.5 GHz Intel Core i5 Memory: 4 GB 1600 MHz DDR3 Graphics: intel HD Graphics 4000 1024 MB  (I include these because I have no idea what affects a computers ability to render but I assume it's one of them, most liekly the graphics card).  So anyways here are the pictures, as you can see I played with changing the resolution, the sample size and the max steps to see if I got different results but it just keeps getting stuck at those 1st four tiles. I've rendered a few other small projects successfully but this was my first time changing some values. I assume i've managed to accidentally change the wrong values and thats causing some conflict thats either stopping the render itself or is making it just too much for my computer.  My goal was the render this particular picture at a good enough resolution and clarity that it could then be made into a poster. So i wanted the resolution to be good and the sampling to be high.       Since writing this there has been no change to any of the numbers at the top of the render result (the time left, etc)
How to integrate PHP forum system with new Django website I am trying to get an intuitive idea of how the  affects Quantum computation. My understanding is that given a qubit $Q$ in superposition $Q_0 \left| 0 \right&gt; + Q_1 \left| 1 \right&gt;$, NCT states another Qubit $S$ cannot be designed such that $S$ is equivalent to the state of $Q$.   Now the catch is, what does Equivalent mean? It could mean either that:   $S = S_0 \left| 0 \right&gt; + S_1 \left| 1 \right&gt;$ such that $S_0 = Q_0, S_1 = Q_1$. Or it could mean that $S = Q$, meaning that if $S$ is observed to be some value ( for example 0) then $Q$ MUST be that same value, and vice versa.    So it seems that point 2, occurs anyways in entangled systems (particularly cat-states), so I can eliminate that option and conclude that that No Cloning states, given a qubit $Q$, it's impossible to make another qubit $S$ such that:  $S = S_0 \left| 0 \right&gt; + S_1 \left| 1 \right&gt;$ such that $S_0 = Q_0, S_1 = Q_1$.

My first attempt at recovery went like this:  $ tar --ignore-failed-read --ignore-command-error -xf tarball.tar tar: Skipping to next header tar: Archive contains ‘180738 0’ where numeric mode_t value expected tar: Archive contains ‘0.445647 -9.’ where numeric time_t value expected tar: Archive contains ‘.259273 ’ where numeric uid_t value expected tar: Archive contains obsolescent base-64 headers tar: Archive contains ‘-0.94874’ where numeric gid_t value expected tar: text from a text file is here: implausibly old time stamp 1969-12-31 18:59:59 tar: more text file contents are here: Unknown file type 'p', extracted as normal file tar: Skipping to next header tar: Skipping to next header tar: Exiting with failure status due to previous errors   This didn't extract much from the tarball before erroring out.

What is meant by a shell is in "vi" mode or "emacs" mode? This question follows directly from . In this case I am specifically unable to understand the part which says:     In that regard, its behaviour is closer to emacs' than with   bash(readline)/ksh/zsh emacs mode, but departs from the terminal   driver embedded line editor (in canonical mode), where Ctrl-W deletes   the previous word (werase, also in vi).   Here we are talking about shells and not editors which are two completely different programs. What does it mean to say shell is in some editor mode?  P.S: You can base your answer on the premise that I understand what a shell is and how to use vim for basic editing. d'Alembert-like functional equation: $f(x+y)+g(x-y)=\lambda f(x)g(y)$ Direct Link to a Comment The increase in the character limit of comments has led them to become as important as the questions and answers that spawn them.

Does anyone know a SF TV short story in which there were blue men who helped "stage" our world- at least the parts we saw, on a minute by minute basis.  So, at each minute, everyone would be in the "world" that was built for that minute, then they would go on to the next "minute world".  The blue men were in the future minutes building most of reality, but only the parts that would be looked at at that minute (to save work, I think - why build something that will not every be "used")  And they were in the past tearing down all the previously lived minutes.  It was kind of a behind the scenes look at why when you set your keys down and come back to them, they aren't there. Then you look again a few minutes later and they are there. The reason in the show was that the blue men building that minute forgot to include your keys, but the next group got it right.  Years later, my wife and I still refer back to that show, so I would like to find out what it was and see if I can find a copy somewhere.  . Show that $\mu (E \setminus A)>0$ if $A$ is a nonmeasurable subset of $X$ and $A \subseteq E$, $E$ is measurable. This question was asked , but the question wasn't asking for an answer, just a clarification on the proof by contradiction they already had, so I'm reposting it to ask for help arriving at the answer.  Because the asker above said they proved it by contradiction, that is what I'm attempting. But I'm having issues wrapping my brain around the concept of set measurability. So let's give it a good college try with what I can understand.  For clarity, $\mu$ is an outer measure.  A is nonmeasurable, so $\exists B \subseteq X$ such that $\mu (B) \ne \mu (B \bigcap A) + (B \bigcap A^c)$.  E is measurable, so $\mu (B) = \mu (B \bigcap E) + (B \bigcap E^c)$.  This essentially means $\mu (B) \ge \mu (B \bigcap E) + (B \bigcap E^c)$ (Since monotonicity is alredy implied by the definition of outer measure).  So we can attempt a proof (or the start of one) by contradiction.  Assume $\mu (E \setminus A)=0$. So $E \setminus A$ is a null set.  So $\mu (B) \ge \mu (B \bigcap E) + (B \bigcap E^c)$. I assume I'm supposed to show a contradiction using that A is nonmeasurable. I'm unsure how.  Another way I think could work would be to use: $\mu (E \setminus A)= \mu (E \bigcap A^c) = 0$ and arrive at a contradiction given that A is nonmeasurable, but again, I'm unsure how.  I just need some direction from here. Thank you in advance for any advice. I am new to Stack Exchange. I know there is a lot of discussion sites for Stack Exchange.

Variations in the pronunciation of "the" Although there are rather simple rules determining the pronunciation of "the", native speakers quite often deviate from these rules (including, e.g., TV shows). According to the Longman Pronunciation Dictionary,     The EFL learner is advised to use [ðə] before a consonant sound (the   boy, the house), [ði] before a vowel sound (the egg, the hour). Native   speakers, however, sometimes ignore this distribution, in particular   by using [ðə] before a vowel (which is in turn usually reinforced by a   preceding ʔ), or by using [ði:] in any   environment, though especially before a hesitation pause. Furthermore,   some speakers use stressed [ðə] as a strong form, rather than the   usual [ði:].   My question is: when native speakers use [ðə] instead of [ði] before a vowel sound, do they do it on purpose or accidentally? If it is on purpose, how do they (typically) decide which pronunciation to use? What is a valid reason to use [ðə] before a vowel sound? resetPassword problem for enterprise users when called from a community? I'm working within a custom application in a customer community that is used by both community-license users and Salesforce enterprise users.  There is a custom Visualforce page where an application admin can select a user and reset the password.  The VF Controller is using the standard System.resetPassword() method.  We are finding that when an enterprise user receives this password reset email, the user can't get to the expected password reset page.  Instead, it eventually redirects to the community login screen.  The password reset URL for these enterprise users is based on the community's URL, and it seems that these users cannot change password through the community -- it has to be through the enterprise URL, like what you get when you reset password via Setup.  Has anyone run into this and found a workaround?  (Of course community users have no trouble with password resets through this Visualforce page.)
