How to use the 3-D scale/rotate tool to create depth in Illustrator? I've a very simple rectangular shape that has been filled with a hexagon texture. I'm looking to create a sense of depth by keeping the lowermost row of the hexagons largest while transforming the top row to be smaller so they are appear to be in the distance.  This would be similar to creating a chessboard like 3-D feel. Any recommendations or proper ways to use the tool without relocating the actual placement of the rectangle – just be inner dimensions?
Illustrator CS5 brick pattern with perspective I created a curving arrow shape that starts wide at the bottom and thins out near the top where the point is. I also created a brick pattern swatch but when I apply it to the shape it appears like the pattern is overlaid instead of like a real road where the bricks follow the shape and narrows near the most distant point. How can I apply a perspective to the brick pattern without looking like I used a clipping mask?  Here is a link to what I achieved with a clipping mask - not what I want though. I need the bricks to look like they are inlaid just like in real life.
3D graphics render as though no illumination Why are there $1 / 1.602176634 \times 10^{-19}$ electrons in a coulomb? Why that exact number of electrons in one coulomb? who decided it? there is nothing wrong with the number, it just seems slightly messy. Why didn't the scientific community just settle on an easier number, such as $1\times10^{-19}$ for example? Can a PC be a lich? The heading says it all, can a PC be a lich? If so, how? The DMG hints that the Book of Vile Darkness contains the secrets of how; there is nothing official otherwise. I have made a script that will sort files according to their extension and place them in the proper folder. For example, place abc.jpg in the directory jpg.  #!/bin/bash #this script sorts files according to their extensions oldIFS=$IFS IFS=$'\n' (find . -type f) &gt; /tmp/temp for var in `cat /tmp/temp` do name=`basename "$var"` ext=`echo $name | cut -d'.' -f2- | cut -d'.' -f2- | cut -d'.' -f2- | cut -d'.' -f2- | cut -d'.' -f2- | cut -d'.' -f2- | cut -d'.' -f2-` mkdir -p $ext mv "$var" $ext/ 2&gt; /dev/null done IFS=$oldIFS   problem with this script:    it involves use of IFS, it is said to avoid use of IFS, as much as possible it does not sorts file without file extensions  it will sort files like abc.tar.bz in folder named bz, but however such a file should go in tar.bz folder see line 9 of my script; if any file contain more no. of dots(in its name) than no. of cut -d'.' -f2- in the script than if will result in file name taken in extension part. for example, a file named i.am.live.in.india.and.i.study.computer.science.txt will be placed in folder named study.computer.science.txt   you may also suggest any tweaks to make this script more smaller and neat. How is it possible to use the GNU find command to match several file types at a time (one search command)?  The man page says:  -type c     File is of type c:     b      block (buffered) special     c      character (unbuffered) special     d      directory     p      named pipe (FIFO)     f      regular file     l      symbolic link; this is never true if the -L option or the -follow            option  is in  effect,  unless  the  symbolic link is broken.  If            you want to search for symbolic links when -L is in effect, use            -xtype.     s      socket     D      door (Solaris)   and I want to search for files (f) and symbolic links (l) and pipe it to another process. How can I search for both at the same time?  I have tried  find -type fl | … find -type f -type l | … find -xtype f -type l | …   I know a workaround would be to use a subshell  (find -type f; find -type l) | …   but I just want to know if it is possible. Why does increasing the number of features reduce performance? Deduction of $\forall y \exists x (x=y)$ Give a deduction of $\forall y \exists x (x=y)$  My thinking is I can prove $\exists x(x=y)$ then use generalization theorem， which is equivalent to prove $\neg \forall x \neg (x=y)$ but I got stuck proving this... thanks in advance  Sorry that I did not specify what deduction system that I want to use here, it is the deduction sequence  where ai is either Axiom or original hypothesis or obtained from MP For some reason, when I try to run any programs (I am trying to run a rootkit hunter: rkhunter) as root on the command line with sudo like this:  sudo rkhunter   Then I get this message:  You must be the root user to run this program   and then I get these lines:  sudo: error in /etc/sudo.conf, line 0 while loading plugin 'sudoers_policy' sudo: /usr/lib/sudo/sudoers.so must only be writable by owner sudo: fatal error, unable to load plugins   I try typing in just sudo but that comes up with the same three errors as above. Also in /etc/ sudo.conf does not exist.  I cannot run any other programs as root through sudo. It was also strange because I could run as root a day ago. I would like it to work.  Just so you know, I am the only user of this computer, and the administrator, running Lubuntu 14.04.1. Neutrino Oscillations and Conservation of Momentum I would like to better understand how neutrino oscillations are consistent with conservation of momentum because I'm encountering some conceptual difficulties when thinking about it. I do have a background in standard QM but only rudimentary knowledge of particle physics.   If the velocity expectation value of a neutrino in transit is constant, then it would appear to me that conservation of momentum could be violated when the flavor eigenstate at the location of the neutrino source is different from that at the location of the interaction, since they are associated with different masses.  For this reason I would think that the velocity expectation value changes in transit (for instance, in such a way to keep the momentum expectation value constant as the neutrino oscillates), but then it seems to me that the neutrino is in effect "accelerating" without a "force" acting on it (of course, since the momentum expectation value is presumed constant, there may not be a real problem here, but it still seems strange).   Any comments? Word: how to show hidden ribbon tabs? How can I control which tabs are available to be opened in the MS Word 2010 ribbon?  Under Word Options > Customize Ribbon > Main Tabs there are several groups checked (Blog Post, Insert (Blog Post), Outlining, Background Removal), but they don't appear on the ribbon even though there is space for them. How is one supposed to turn them on or get to them?  The one in particular I'm after today is the Blog Post tab, which I know I can get to in a round about way via File > New > Blog Post Template. However I don't want a new post, rather an old one, which means File > New > Blog Post Template > Open existing > [select from list] > [close new blog post window] > [slap No I don't to save darn it]. Extra work for nothing is irritating; how do I get Blog Post (or Outlining or ...) to show up in that nice empty space next to AddIns? carrier concentration - distance graph of PN junction i am trying to plot the distance-carrier_concentration graph above with these formulas:   -and-  (p-side: x &lt; -xp , n-side: x &gt; xn) But i could draw only red lines on the graphs with these formulas. How can i or with what formula draw black lines on the graph that majority carrier and space charge region concentration? I am new and i need your help :) Thanks in advance. How can I check for Python version in a program that uses new language features? If I have a Python script that requires at least a particular version of Python, what is the correct way to fail gracefully when an earlier version of Python is used to launch the script?  How do I get control early enough to issue an error message and exit?  For example, I have a program that uses the ternery operator (new in 2.5) and "with" blocks (new in 2.6).  I wrote a simple little interpreter-version checker routine which is the first thing the script would call ... except it doesn't get that far. Instead, the script fails during python compilation, before my routines are even called. Thus the user of the script sees some very obscure synax error tracebacks - which pretty much require an expert to deduce that it is simply the case of running the wrong version of Python.  I know how to check the version of Python. The issue is that some syntax is illegal in older versions of Python. Consider this program:  import sys if sys.version_info &lt; (2, 4):     raise "must use python 2.5 or greater" else:     # syntax error in 2.4, ok in 2.5     x = 1 if True else 2     print x   When run under 2.4, I want this result  $ ~/bin/python2.4 tern.py  must use python 2.5 or greater   and not this result:  $ ~/bin/python2.4 tern.py    File "tern.py", line 5     x = 1 if True else 2            ^ SyntaxError: invalid syntax   (Channeling for a coworker.) Are these solutions of $2 = x^{x^{x^{\:\cdot^{\:\cdot^{\:\cdot}}}}}$ correct? If you have the ability to cast a spell without a spell slot, can you cast that spell using a spell slot?

MySQL get missing IDs from table Manifold that is NOT smooth Could someone provide an example of a manifold that is not smooth? All manifolds that come to mind are smooth! By a manifold, I mean a hausdorff, second countable locally euclidean space. Determining relationship (e.g. number of removes) with cousin? How do I figure out if someone is a first cousin, second cousin, cousin once-removed, etc? I have looked in several different Fate games' rulebooks, including Fate Core, DFRPG, Atomic Robo, FAE, and Jadepunk, which all describe Boosts as temporary Aspects you get to invoke for free, one time, and which disappear after being invoked.  In the other "invoke for free" situation I'm aware of (on Aspects newly-created via the Create Advantage action), they aren't singled out as "temporary."  I looked in many books but I'm interested in Fate Core.  So I haven't been able to figure out whether Boosts need to be invoked immediately or they disappear, without having been invoked at all? How precisely do I need to post close to 7:00 (somewhere) to get hero of time? Timezones... are complicated. We have full hour offsets, half hour offsets...  And time keeping isn't always accurate. So does the Hero Of Time hat assume full or half hour offsets (or literally any timezone) and how close to 7:00 at somewhere do I have to post for my hat?
