Its a question about Excel Data guys plz help me
What is a NullPointerException, and how do I fix it?
Can Ability Score increases caused by magic items qualify me for feats? As far as I know, only a player character's non-temporary ability scores are considered for taking feats, taking prestige classes, etc. Meanwhile, any ability bonus that comes from spells, or magic items that are in effect only while worn, is not counted (except tomes which increase abilities permanently).  So a Fighter with low Int who wants to qualify for Combat Expertise can't use spells or items that gives an Int bonus to raise it high enough to qualify. Is that right?  For example:  Say our fighter has Str 12, so he can not take the Power Attack feat. Suppose he asks for a spell from the wizard to make his Str 16, or to borrow a ring which provides +4 Str from another character. (Or any other method that will provide him a non-permanent bonus). His Str is now 16. Can he take Power Attack with that non-permanent bonus now? Because after the spell duration ends or he takes off the ring, his Str score will be to low again to qualify for Power Attack.

Can somebody show me the method? I am a little confused. Define a new block environment in LaTeX beamer I have two kinds of examples in my document. I want to use different colors, say, red and blue. This is what I am doing now.  \documentclass[]{beamer} \usetheme{Madrid} \begin{document}  \begin{frame} \frametitle{Test} \setbeamercolor{block title}{fg=white,bg=red!75!black} \begin{block}{First Kind Example} This is example of the first kind. \end{block} \setbeamercolor{block title}{fg=white,bg=blue!75!black} \begin{block}{Second Kind Example} This is example of the second kind. \end{block} \end{frame}  \end{document}   I know this is kind of stupid. I want to define two new block environments, one for each color, so I don't need to use setbeamercolor every time I use them.   \begin{block1}{First Kind Example} ... \end{block1} \begin{block2}{Second Kind Example} ... \end{block2}   I know I need to define these two new environments in the preamble, but don't know how. Thanks for the help.  By the way, what is a good reference on these kinds of tricks in LaTeX/beamer? Any recommendations? Annuity notation in LaTeX Why can't Inuzuka clan's dogs use human language?

I was wondering if it's possible to run an Ubuntu virtual machine using VirtualBox in background, I mean, without any window open.  The idea is to connect via SSH to the Linux host, that would be running in background.  Has anyone ever done something like this? Is it possible? As I understand this, firewalls (assuming default settings) deny all incoming traffic that has no prior corresponding outgoing traffic.  Based on  and , reverse SSH tunneling can be used to get around pesky firewall restrictions.  I would like to execute shell commands on a remote machine. The remote machine has its own firewall and is behind an additional firewall (router). It has an IP address like 192.168.1.126 (or something similar). I am not behind a firewall and I know the remote machine's IP address as seen from the Internet (not the 192.168.1.126 address). Additionally, I can ask someone to execute ssh (something) as root on the remote machine first.  Could anyone explain me, step by step, how reverse SSH tunneling works to get around the firewalls (local and remote machines' firewalls and the additional firewall between them)?  What is the role of the switches (-R, -f, -L, -N)? sum of noncentral Chi-square random variables I need to find the distribution of the random variable  $$Y=\sum_{i=1}^{n}(X_i)^2$$ where $X_i\sim{\cal{N}}(\mu_i,\sigma^2_i)$ and all $X_i$s are independent. I know that it is possible to first find the product of all moment generating functions for $X_i$s, and then transform back to obtain $Y$'s distribution. However, I wonder whether there is a general form for $Y$ like the Gaussian case: we know the sum of independent Gaussian is still a Gaussian, and thus we only need to know the summed mean and summed variance.   How about all $\sigma^2_i=\sigma^2$? Will this condition make a general solution? I asked a question that has been marked as a duplicate. I read a lot of similar questions and explanations in advance but I couldn't find a solution. In the question that should answer my question the asker used a different (not working) approach. There is even an answer that would work for my case however I'd rather consider it as a workaround than a solution since I have seen examples using my approach.  So I would like your opinion in that case. Would it be ok to repost my question while explaining why other answers didn't help me? I edited my question but I think it's not getting any attention anymore. Naturally I will remove the old question. The error: "mount: only root can do that" while mounting a partition How do I set bold and italic on UILabel of iPhone/iPad? I've noticed the text of the Hot Meta Posts box is not within its limits. I guess this would happen for any question with a word that's long enough: jQuery - regexp selecting and removeClass()? I've posted a lot to StackOverflow, and I've noticed something kind of irritating with the formatting in writing questions and comments. If I need to put something inside a &lt; and a >, without spaces in the middle (like right there), it will think it's code and not show up, like this   (obviously it won't come up what I wrote there, or else this wouldn't be an issue, but if you open up the question to edit you can see what's written there.)  If I want it to show up, right now I have to add an extra set of brackets inside of the originals with a junk variable, like right &lt;here> (again, open in edit window to see).  This is really annoying when trying to show variables like lists that require those brackets, and I feel like the junk variables could confuse people looking at the edits. Is there a way to get around this formatting? Thanks! Remap Caps Lock to Ctrl-b
