How to add vias and more traces?
How do we know an $ \aleph_1 $ exists at all? I have two questions, actually. The first is as the title says: how do we know there exists an infinite cardinal such that there exists no other cardinals between it and $ \aleph_0 $? (We would have to assume or derive the existence of such an object before we label it something like $ \aleph_1 $.)  My second question is, can we say for certain if there's any limit to the number of cardinals existing between $ \aleph_0 $ and continuum (i.e. $ 2^{\aleph_0} $)? I mean, how could we know that there&#39;s not an infinite number of cardinals between the two - perhaps even more than $ \aleph_0 $?

I am not able to sum all the opportunities under the account ?  How will I do that?  What I have to use in this to run the trigger? Is it possible to create because opp. is child and account is parent ?  trigger sumAllopptyAmtAccount on Account(before insert) {     Set &lt; ID &gt; AccID = New Set &lt; ID &gt; ();     if (Trigger.isInsert)         for (Account oppAc: trigger.New) {             AccID.add(oppAc.AccountID);         }     List &lt; Account &gt; acc = [select id, SumAll_Opprty__c from Account where id in: a.AccID];     List &lt; Opportunity &gt; opp = [selece id from Opportunity where AccountID in: a.AccID];     for (Account a: acc) {         a.SumAll_Opprty__c = con.size();     } } How to specify font size less than 10pt (or more than 12pt)? I seem to have screwed up something that allows you to inset evenly, I think I have tried every combination of settings in inset and pivot center and even is far from even.  I tried uninstalling and re installing blender 2.71 and get the same result.  The image attached is a simple default cube that I tried to inset evenly.  I have also attached the blend file link  help?? Identical creatures entering the battlefield Start script on open blender file How to change an application icon programmatically in Android? Does 'but for' mean:  'If we had X (but we didn't), Y would have been the consequence'?  Or can it also mean; because we had X, as a result Y happened?   Some different examples of but for:  (Case 1)     But for a cup coffee, it was to be a productive day of writing.   Unfortunately, I'd run out, and spent the day craving.    (Case 2)     But for the glass of wine I had dinner, the house work didn't get   done.   (Case 3)     But for the glass of wine I had for dinner, I would have got the   house work done   What is the correct usage of "but for"? Proving a function is Lipschitz continuous Show that the following function is Lipschitz continuous and find a Lipschitz constant  $$y\mapsto f(x,y)\\ f(x,y)=\frac{y}{x}\ln(\frac{y}{x})\text{  , } |x-1|\leq\frac{1}{2}\text{  , } |y-e|\leq\frac{e}{2} $$  I have no clue on where to begin to prove this.   My first question is how I should interpret this function, is $x$ a sort of constant? How can I limit ssh *remote* port forwarding? I need to limit which ports can be remotely 'ssh -R' forwarded by an user.  I know about permitopen option on authorized_keys, but as it says on man page it only limits local 'ssh -L' port forwarding  As discussed  a user would get the same with netcat or similar, but in this case user has no shell access  I also found  that talks about using selinux or LD_PRELOAD, but I never configured selinux before and can't find info on how to do that with LD_PRELOAD.  maybe someone have made a patch for openssh to implement that?  EDIT: I've found  so I guess it's not yet implemented After considering the answers to my previous question (), I've decided to take the 4 or so repositories I have and consolidate them into one. This of course leads to the question, what's the best way to do this?  Is there a way to combine two or more repositories maintaining the version history for both?  Edit: I should also point out that I'm using Assembla.com, which does not provide access to the svnadmin command, AFAIK  Another edit: Does this even matter? If svnadmin works on URLs, then it's no problem then. derivative under integral intuition Is it true that a language is regular? Is it true that for every regular language $L \subseteq \{0,1\}^*$, language $\big\{ w^{|w|} \big| w \in L \big\}$ is regular? I don't know how to prove that.Could you give me a hint? Thank you Destroy chunked block like Minecraft Another phrase for "a chicken and egg situation" Is there any other phrase that conveys the same meaning as  the phrase "a chicken and egg situation" especially if one has to use this phrase in an official/corporate set up? What are some alternatives to "hover" on touch-based devices? Came up recently in a 37signals podcast:    The straightforward, "brute-force" solution is to just use the first touch on a UI object as the hover.    It works. But are there other, more elegant solutions? For instance, could the hardware ever be made to support actual finger hovering? Always sort Recent Places by date modifed
