Shape gets distorted when adding stroke in Illustrator CS6 I very recently started learning how to use Adobe Illustrator (CS6), and just now I noticed something strange. When I add a 1pt stroke to my shape, it gets slightly distorted. This distortion does not disappear if I remove the stroke. (But only if I remove the stroke by setting its weight to 0. Using CTRL+Z does return the shape to its former state.)  After adding and removing the stroke a few times, the difference becomes quite noticable:   Am I doing something wrong? Is it a bug? I can't imagine this being the expected behaviour.  EDIT: I think I figured it out. Appearantly, turning 'Align to pixel grid' off doesn't affect previous shapes. If I turn it off and then recreate my shape from scratch, the problem is fixed.   However, I was wondering if their is a way to disable the effect for existing shapes. In other words, can I 'fix' the shapes I created while 'Align to pixel grid' was still on? Prove that $\sum_{r=1}^nr(r+1)=\frac{n(n+1)(n+2)}{3}$ using induction $$\sum_{r=1}^nr(r+1)=\frac{n(n+1)(n+2)}{3}$$  could you help me with how exactly I work this out? Hint:  $a^2 -ab +b^2 = (a+b)^2 -3ab.$  I know we can say that there exists an $x,y$ such that $ax + by = 1$.  So in this case, $(a+b)x + ((a+b)^2 -3ab)y =1.$  I thought setting $x = (a+b)$ and $y = -1$ would help but that gives me $3ab =1.$  Any suggestions?

Context and Chronological info I'm trying to find the title/author of a short story that I read in some or other anthology ages ago. I couldn't give you an exact date but I'd say it was probably 50s/60s. Plot The human population has increased to the point where input and output of resources on Earth is in exact equilibrium. As such, no other living matter can be permitted to exist, as its use of resources would throw this equilibrium out of balance. One man in a vast tower block has managed to hide some flowers, and, I think, one or a few small animals - perhaps a mouse. These are detected by the relevant authorities, and the story ends when an official arrives at the apartment and requires the man to destroy them - the last non-human living things on Earth.

Mass Lead Conversion - Programmatically or Using Data Loader Delay in approval leads to missing out on being awarded an "Explainer" badge Singular vs. Plural with Multiple Gerunds as Subject (IE: [Gerund] and [Gerund] are/is [something].) I'm trying to find out whether I should use a singular or plural verb when there are multiple gerunds as the subject of the sentence. For example:  Running the correct course and keeping a steady pace are/is necessary in order to win.  With either one of these by itself, &quot;is&quot; would be correct:  Running the correct course is necessary in order to win. Keeping a steady pace is necessary in  order to win.  With both gerunds combined, I can't seem to figure out whether the verb should stay singular since each phrase is singular, or if it should become plural since there are two connected by &quot;and&quot;. If we just treat the gerunds as regular nouns, then obviously it would become &quot;are&quot;, but I'm not sure if gerunds have the exact same rules as regular nouns. I know that if the sentence was:  Running the correct course and keeping a steady pace are both necessary.  That &quot;are&quot; would be correct, but without the &quot;both&quot; it sounds incorrect to me. Does anyone know the official rule here?
