How to use Voxelmap on different versions of Minecraft on the same computer
How can I have 2 different mod folders with the new Minecraft launcher?
What security systems and processes are in place to prevent malicious third parties from hacking/compromising the security of code in the Debian mirrors, or to verify that the packages we get are in fact the ones the maintainers think they are? I practise before the real analysis exam and I got stuck on few excercises.  "if $F$ is an antiderivative of a continuous periodic function and $F$ is bounded, then $F$ is periodic"  $~\to~$ one should give a proof or counterexample.  (I'm convinced it's true, but how to prove it?) Noun-adjective reversal - was it ever in use in plain speech? Reciprocal of Holder's inequality Does anyone know how to do this exercise? I couldn't do it.  Let $(X,S,\mu)$ be a $\sigma$ -finite measure space and $g\in M(X,S)$ such that $gs\in\mathcal{L}_1$ for any simple function $s\in\mathcal{L}_p$, $p\in(1,\infty)$. Suppose there is $A\geq0$ such that $\left|\int gs\,d\mu\right|\leq A||s||_p$ for all $s$. Show that $g\in\mathcal{L}_p$ with $\frac1p+\frac1q=1$ and $||g||_q\leq A$.

Abnormal behavior with iwlwifi driver: the device is shown as not working Recently I've installed Kubuntu in a newly bought laptop with an Intel WiFi 6 AX200 network card, I can connect to the wifi without apparent problems but when I open the driver manager in the settings I face this weird situation:  Intel Corporation: Wi-Fi 6 AX200 This device is not working.

How to I make Cisco WebEx work with 13.10 64bit? I'm having a very hard time getting webex to work under Saucy.  Up until now I've been able to just install a java plugin, install ia32-libs, and I was good to go.  With Saucy ia32-libs is gone and it's up to us to figure out which 32-bit libraries we need to install.    So the question is, how do I install WebEx on 64bit Saucy without ia32-libs? How to sum up values of each two rows across their line in linux I am working on a print for my wall and I am trying to create something like this:      I have already created the letters in Illustrator and now I am adding the colors in Illustrator and then exporting everything to Photoshop and then using the liquify tool to blend the colors to create a similar effect. I also used the healing patch tool to blend in the hard edges.  Is that the right way of doing it? Or is there another way? Is it true that a subset that is closed in a closed subspace of a topological space is closed in the whole space? I have a non homework related question from a text and require a nice clear proof/disproof please  Is it true that a subset that is closed in a closed subspace of a topological space is closed in the whole space?  my ideas:  if $H$ is the subset of the topological space $X$  if the subset is closed in the closed subspace, the complement is open in the subspace, which means the complement is of form $U\cap H$ for some $U$ open in $X$  if the subspace is closed the complement is open which means complement of $H=U$ for some open $U$ in $X$  kind thanks What are some practical examples of a constant current source? Please don't state the obvious that nothing is a perfect constant current source.  And please do not give examples of how to create them from components.  I looked at this  which stated the obvious - that you can not have a perfect current source.  So when I say constant current source, I am not referring to the mathematical concept used in circuits, but "natural" components that provide a close approximation to this. Key word is approximation.  A bit of research pulled up one interesting example which was a solar cell.  Is this a valid example?  A google search pulls up a similar Quora question . Which gave the example of a solar cell.  This is a more technical site and I was looking for a more engineering answer not a mathematical or laymen's answer.  Thanks. Grep equivalent for Windows 7? Is there a command prompt  equivalent for Windows 7? That is, I want to filter out the results of a command:  Bash use:  ls | grep root  What would it be from a Windows command prompt? Are old (>35) faculty candidates discriminated against all over the world? I think that in India research institutes will never take a faculty candidate who is over 35. Is it so all over the world?   I am asking this question from the point of view of if someone starts their PhD. at the age of 27 then its unlikely they will be faculty candidates till they are 40. What are the good ways to migrate a RAID array to bigger disks? $\forall x,y>0, x^x+y^y \geq x^y + y^x$ Prove that $\forall x,y&gt;0, x^x+y^y \geq x^y + y^x$   A friend of mine told me none of the teachers in my school have succeeded in proving this seemingly simple inequality (it was asked at an oral exam last year). I tried it myself, but I made no significant progress. How can I find hard links on Windows? I've created some hard links on my Windows 7 file system using mklink. It was some time ago and I can't remember for sure where, or which files. When I use Explorer, all files look the same. When I use the command line and type "dir", they all look the same.  How do I find hard links? Or how do I determine whether a specific file IS a hard link? How do you secure wood framing to a concrete basement floor? How do I make windows save their position on screen after re-attaching a display? When I attach a second monitor to my MacBook, I drag many windows onto it.  When I detach the monitor, all the windows move back onto my MacBook's display.  How can I make it so that when I re-attach the monitor, all the windows automatically move back to their position on the second monitor again?  I use my personal MacBook at work where I have the extra monitor.  But this means I need to detach and re-attach the monitor every day.  I have many windows I leave open from the previous day's work, so this is a real pain.  I know about an app called , which is almost exactly what I want.  But I need something that works on OS X 10.5.
