I came across the :    Which states:     $\pi$ Pi      Pi is an infinite, nonrepeating $($sic$)$ decimal - meaning that   every possible number combination exists somewhere in pi.  Converted   into ASCII text, somewhere in that infinite string of digits is the   name of every person you will ever love, the date, time and manner    of your death, and the answers to all the great questions of    the universe.   Is this true? Does it make any sense ? Is there any way to increase the drop rate of items? Macbook Pro hard drive failing? Can whole chilli peppers be frozen? I have some  chilli peppers bought from the local supermarket.    Aren't they lovely?  :)  Well, unfortunately, my local supermarket (I think the only one in the UK that stocks them) doesn't always have them in stock, so when they do appear on the shelves, I quickly stock-up on them.  Storing them in the fridge, they'll last maybe a week or so before starting to deteriorate.  My question is, can these chili peppers be frozen and, if so, will freezing them have any "negative" effects ?  I buy these particular peppers for their heat (and also their great smoky flavour), so I'd hate for either the heat or the flavour to be negatively impacted if they were frozen. I have just upgraded to Ubuntu 17.10 and found out there is no option to have 2 by 2 workspaces. I was able to configure 4 "static" workspaces using , but I would like to have them in 2 rows by 2. Any ideas? I have a question about subsets $$ A \subseteq \mathbb R $$ for which there exists a function $$f : \mathbb R \to \mathbb R$$ such that the set of continuity points of $f$ is $A$. Can I characterize this kind of sets? In a topological,measurable or in some way? For example, does there exist a function continuous on $\mathbb Q$ and discontinuous on the irrationals? Combine 4 cells in a table Here is a simple table.  I want to merge 4 cells. I want to combine the three "this" cells area in this table. I thought I have to use multirow and multicolum at same time. However, I could not find how to use it.  If possible, could you post the modified LaTeX source code?

They've removed many buttons, most of the preferences, and have in general made it impossibly oversimplified and difficult to use.  Old Skype was fine when I had windows 7.  Is there any way to get it back on Windows 8? Basically the question is how to get from this:   foo_id   foo_name 1        A 1        B 2        C   to this:   foo_id   foo_name 1        A B 2        C Why does the p-value double when using two-tailed test compared to one-tailed one? Since this has been marked as a duplicate, I want to clarify that it's not about critical values of one- vs two-tailed tests, but the calculation of the p-Value in this case.  I get that in a two-tailed test, you look at both sides of the distribution and therefore you split alpha in half and you need a more extreme test statistic to get a significant result (at the same alpha level).   In my understanding, the p-value is the probability to get this or a more extreme test statistics if the H0 is true. This is easily calculated for a one-tailed test: I just calculate the integral right of the empirical test statistic    For a normal distribution, a z-Value of 1.645 gives me a p-Value of ~0.05. But if I do the same procedure with a two-tailed test, SPSS/Excel doubles the p-value. I get that you now look on the other side of the distribution as well, and therefore I think it's the integral of z(test statistic) + z(-test statistic), but why? I did not get the result -1.645, so I don't understand why I should add the 2.5% of the other side. Storing the original document class page layout with geometry Is causality a formalised concept in physics? How would you do a "not in" query with LINQ? I have two collections which have property Email in both collections. I need to get a list of the items in the first list where Email does not exist in the second list. With SQL I would just use "not in", but I do not know the equivalent in LINQ. How is that done?  So far I have a join, like...  var matches = from item1 in list1 join item2 in list2 on item1.Email equals item2.Email select new { Email = list1.Email };   But I cannot join since I need the difference and the join would fail. I need some way of using Contains or Exists I believe. I just have not found an example to do that yet. Can someone please give me the prerequisites and mathematics required for string theory? Are there some good references to study it, both online and in a book? Please consider I am a newbie in string theory, and only about up to the level explained in Hawking's Brief History of Time and Penrose's Road to Reality. I would prefer something which does not omit rigor, but builds it up.Also, are there good online lectures on this?  (I have covered most of GR, but I am not really comfortable with advanced Quantum mechanics. I have studied QM only from Griffith's book, and a few McGraw hill lecture notes.) What does "Baking" mean? I want to make some cool items for Dota 2 and I'm reading a guide. There are some tips about baking  etc. but I can't use them, because I don't even know what baking means. Can somebody explain this, please?  Thanks for all answers. How to use the SSD for caching in Windows without Intel Smart Response? My motherboard is Asus P8B75-M. It doesn't have Intel Smart Response. But recently I bought a SSD. Since I mostly use linux I have Linux installed in it. But can I use it to speed up Windows also? How? I don't have Smart Response... (I run Windows 8.1). The SSD is only 64GB. Node only partially rendered near edge of plot I'm trying to draw a relatively simple chart of a number line, and when one of the nodes is too close to the edge of the plot, it gets cut off.  The code:  \documentclass{article}  \usepackage{natbib} \usepackage{graphicx} \usepackage{pgfplots}  \begin{document}  \begin{tikzpicture} \begin{axis}[   width=\columnwidth,   axis y line=none,   axis lines=left,   axis line style={-},   xmin=0,   xmax=1,   ymin=0,   ymax=1,   xlabel=$\mu$,   scatter/classes={o={mark=*}},   restrict y to domain=0:1,   xtick={0,1} ] \draw[ultra thin] (axis cs:0, 0) -- (axis cs:0,.05); \draw[ultra thin] (axis cs:.4, 0) -- (axis cs:.4,.05); \node[coordinate,label=above:{$B$}] at (axis cs:0.0,0.05) {}; \node[coordinate,label=above:{$A$}] at (axis cs:0.4,0.05) {}; \node[coordinate,label=above:{$b$}] at (axis cs:0.2,0.02) {}; \node[coordinate,label=above:{$a$}] at (axis cs:0.7,0.02) {}; \end{axis}; \end{tikzpicture} \end{document}   The Result:    How do I get the B to fully render? Related posts:    These posts are different from mine in that they merely ask for the &quot;votes&quot; tab back or ask if it is at all possible to get such information, while I propose how to implement this as a search feature. Background I recently found myself facing a problem very similar to one that I had solved before. I remembered that I found the solution on SO and I remembered upvoting the post containing the solution. I wasn't able to find that particular post by just searching with relevant keywords. It would have been nice if I could search only among the questions I have voted on. I searched on meta and found that there had been a tab for looking at what you've voted on, but that it was removed due to lack of interest. This is understandable, since just listing the hundreds/thousands of posts you've voted on isn't particularly useful. Proposal What I want is to be able to search for posts I've voted on similarly to the way I'm able to search on my posts within a specific tag. For instance: user:310121 [iphone] apple  This will return all my posts tagged iPhone, where I mention Apple. This is brilliant. This is just how I want search to work. Now what I want to do is to extend this to include votes. The exact syntax isn't relevant, but I had to make one up to show you what I mean: To show all posts you've voted on: user:310121 {votes}  To show all posts you've upvoted: user:310121 {upvotes}  To show all posts you've downvoted: user:310121 {downvotes}  You could probably omit the the user part, since you're only allowed to see your own votes. (Unless it's desirable to be able to look at other peoples votes. Maybe you should be allowed to do this if you have enough rep? Well, that's another discussion.) I guess that even if you're allowed to see other peoples votes it would make sense to display your own votes if the user part is omitted. So in my case I could have done the following search and found the post I was looking for: {upvotes} keyword  Lastly I just want to suggest that clicking on your vote count will work just like clicking on a tag. If I click on a tag in my profile the following search will be done: user:310121 [tag]  So if I click on my upvote count the following search should be made: user:310121 {upvotes}  The same goes for downvotes: user:310121 {downvotes}  This would be a very useful feature and it wouldn't be intrusive in any way. The users that don't care for this feature might never know that it's there. And just for the record the favorite system doesn't replace this feature. window-switching keyboard shortcuts interfere with emacs and cannot be changed in the main keyboard system preferences A good title helps your question get the attention it deserves.
