I uninstalled and re-installed steam. I didn't uninstall my games, and they still exist on my hard drive (I checked).  I have an SSD and a HDD, and to save space I install programs (including steam) to C:\Program Files (x86)\Steam drive (SSD) and games to D:\Games\SteamApps (HDD). How to I let steam know the programs are installed there? Is there any way to save the order of spaces in Mission Control? Using apt-get to remove packages and dependencies Effect of switching response and explanatory variable in simple linear regression Programmatically Create X509 Certificate using OpenSSL I have a C/C++ application and I need to create a X509 pem certificate containing both a public and private key.  The certificate can be self signed, or unsigned, doesn't matter.  I want to do this inside an app, not from command line.  What OpenSSL functions will do this for me?  Any sample code is a bonus! I looked around but did not find that anyone has asked this before, but what are the fonts that are standard/recommended while writing academic reports/papers? There are some sections of tracks that allow you to deploy your hang glider or parachute.  This allows you to glide in relative safety until you hit the track again.  But you can also hit forward or back on the control stick to tilt down or up, respectively.  Is there an advantage to staying in the air?  Or does heading back down towards the track give you more speed than just gliding along?

Problem statement  Prove that if $A$ is an uncountable set and $B$ is a countable set, then $A\setminus B$ must be uncountable.  What I think  The statement does not mention $A$ and $B$ relationship. I think there are two possibilities:   If $A \cap B = \emptyset $, then $A\setminus B$ is trivially uncountable If $A \cap B = B$, then $B \subset A$ and as a bijection can not be made between $A\setminus B$ and $\mathbb{N}$, $A\setminus B$ is uncountable.   And there is where I'm stuck. How can I prove that a bijecton can't be made?  TIA. What's the section of the soundtrack used in the second episode of R2 at 8:00, after Kallen defeats a Knightmare and Lelouch gives new orders, called? I want to model the transfer function of a resistor mathematically, and am after some resources / tips on if it's possible to do so.  For example, if I put 1V into a 1 Ohm resistor, I want to know how long and how (shape) it will take to reach a steady state temperature, given 25 deg C ambient.  I.e.   $$ \frac{T(s)}{V(s)} = ??? $$  Where T(s) is the laplace transform of temperature T(t), measured in say Kelvin.  I understand there are a lot of factors which will affect this model (material, size, shape, ambient (?)), but I'm not sure where to even start. A  shows the heat rise at a certain load, but not really how it gets there. I can't find a time-domain function for the temperature rise either. A linear operator commuting with all such operators is a scalar multiple of the identity. Is there a 'rule of thumb' on the upper limit of how many related records in related objects an object should have to avoid slow page loading? Typically, each record in Salesforce will be 2kb large: .   However, let's say in an extreme example, the Opportunity object is related to 40 custom objects, each which has 100,000 records. The page would load much slower, especially in an older browser version.   1) Is there a 'rule of thumb' as to what the upper limit of how many related records an object should have?   2) Also, , there's an indication that there's some sort of tier-tuning per org based on the volume of data it has. Is that correct? And if so, are the volume ranges and respective tier-tuning capacity available? Does "FN" stand for or mean anything? A word for "mercy killing" "Mercy killing" is an act of killing someone who is already dying and in terrible pain, in order to reduce his or her suffering.    Is there any single word for "mercy killing"? Feed lists answered questions as "unanswered" Is it possible to retrieve a previous un-evaluated, un-normalized input? May someone help me? I am trying to use induction to prove that the formula for finding the $n$-th term of the Fibonacci sequence is:   $$F_n=\frac{1}{\sqrt{5}}⋅\left(\frac{1+\sqrt{5}}{2}\right)^n-\frac{1}{\sqrt{5}}⋅\left(\frac{1-\sqrt{5}}{2}\right)^n.$$  I tried to put $n=1$ into the equation and prove that if $n=1$ works then $n=2$ works and it should work for any number, but it didn't work. I need to prove that this formula gives the $n$th Fibonacci number.
