How much mana should I put in a deck with Mountains and Forests? How much of each? I counted the mana in my black deck to see how much I need, but I still don't know.
When choosing cards for a deck, one of the most important things to consider is the number of land you put in. The biggest issue is mana curve, of course. What shortcuts are best for determining the proper amount of land with a given mana curve?
Short story about a man stranded on a red planet with a sentient hand as his friend I remember reading a short story 10 to 15 years ago about a man stranded alone on a red planet, where nothing would be green, and so he would miss that color. There was a sentient hand to keep him company, and it talked to him. I don't remember if the hand was a native life form or his own hallucination.  The story was not very old at that time, so it may have been written in the late 90s or 00s. Is there a difference between single and double quotes in Java? What graphics packages are there for creating graphics in LaTeX documents? $ d_1,d_2\mid n\iff {\rm lcm}(d_1,d_2)\mid n\ $ [LCM Universal Property] unblock slime presta valve My Son's bike has slime inner tubes.  The bike has been sitting in the garage since last summer and the front tyres valve now seems blocked.  Its has what feels like 15-20 psi in it but I can not get the valve to let any air out or take any more in.  I have no idea at this point how to get it to unblock the valve so I can use it again.  For that matter I don't know how I could get the tire off as it has a reasonable (not ridable) amount of air in it without slashing the tyres (nice kings 2.2 which are pretty new).  I have tried putting the pump on it and putting a bit of air into it to try and clear the blockage but that didn't do anything.  Any ideas please? Disabling Intel Turbo Boost in ubuntu I cannot remember anyone writing the letter epsilon in any other way than \varepsilon in any math class; but in LaTeX \epsilon and \varepsilon are different symbols. Do any of you know why there are two different symbols? (I.e. if \epsilon is the correct way to write the letter epsilon, why aren't mathematicians using it, and when is, according to the standards today, the correct situation to use each of the symbols?) Is there a safe way to run a diff on two zip compressed files? Seems this would not be a deterministic thing, or is there a way to do this reliably? Wouldn't it be nice if we have a command to end an environment in a generic way? Example:  \begin{itemize}    \item Apple    \item Banana \endenv       % replaces / is an alternative to, \end{itemize} or any other environments.   so that if I change my mind, I can just replace the first line with, for instance, \begin{enumerate}, without changing the closing part. This is also useful when one changes from normal to starred environment, etc.  This feature would serve as an alternative to the normal closing, which will still be available. And this hypothetical \endenv can be restricted to work only for 'normal' environment, and will not work for complex ones such as verbatim, frame, listings.  Should we have that \endenv? Is there already a package for this feature?  Edit:  To future visitors: from the accepted answer below one can see that this is not a very good idea. If one still demands the presumed convenience, this kind of thing should/can be delegated to the editor. limit of $\lim\limits_{x \to \infty}((x+1)^a - x^a)$ Hello everybody, i couldn't figure out how to demonstrate this equation without L'Hopital i wonder if its possible.   $a \in (0,1)$ $\lim\limits_{x \to \infty}((x+1)^a - x^a) = 0$ When applying to a PhD program in the US, how does the admissions process work? If an applicant is weak in a particular area, is it possible to offset that by being strong in a different area?  Note that this question originated from this . Please feel free to edit the question to improve it. Why won't this ocelot do anything but breed? Current situation: I'm required to cite "normative" documents (read: standards and manuals) separately from articles and books etc. Using biblatex and biber with the numeric style I'm doing that by issuing multiple printbibliography commands like so:  \usepackage[style=numeric,backend=biber,bibencoding=utf8]{biblatex} %... lots of stuff \printbibliography[type=standard,title=Standards \&amp; Manuals] \vskip\baselineskip \printbibliography[type=manual,heading=none] \printbibliography[nottype=standard,nottype=manual]   which gives a heading Standards &amp; Manuals, prints a list of manuals, leaves a bit of space then the list of standards and finally, under a new heading Bibliography gives books and articles etc. Thus far everything is fine, enter:  The Problem: I'm using the shorthand field in my database for the standards and manuals which works perfect as far as output within the text is concerned and sets the shorthand as the label in the bibliography and prints the details to the right of it - problem is: my shorthands are considerably longer than the labels generated by the numeric style, but even though they're in three different \printbibliography commands, everything gets indented to the maximum width of the label, making the part for books and articles look quite ridiculous.  The following shows the problem with only two separate \printbibliography (and an obviously exaggeratedly long shorthand):   Now  what I would obviously want is for each of the \printbibliography commands to only use the indentation actually necessary to accommodate the largest label appearing within, i.e. rendering the Manuals section as above, but the Bibliography section like follows:   Can anyone help me to achieve this? Or give me some pointer where to look?

I have hundreds of PDF files (related to documentation etc.) on my computer (Windows machine), and very often I receive/have to send dozens of PDFs via email. It is now a normal routine that the PDF I receive or send is corrupted. This creates serious trouble sometimes, when the source file (e.g. Word file or the Tex file) is missing/not available instantly. Checking these thousands of PDFs is not possible in finite time, so I have searched for a tool which I can run once and it would scan all PDFs (in directories and sub-directories), and finally I would get a list of files which I should re-create. Up to now, it seems there is no such tool. When I spoke with a friend of mine, I had noticed she used sentences similar to "I need to go buy food."   Is it correct to say "to go buy," or should I say "to go to buy"?    I know that I could say "I need to buy food," but I think that in "I need to go buy food," who is speaking is putting in evidence s/he needs to go and that s/he cannot stay any longer, or that her/his time to stay is limited.
