What are the good ways to migrate a RAID array to bigger disks?
INT(5) vs SMALLINT(5): numbers in parenthesis after the numeric type In MySQL table definitions is there a different between INT(5) and SMALLINT(5)?  Or do they both represent the same size? How to link dataframes in ArcGIS or QGIS? The below image shows a layout in ArcGIS 10.1 with four dataframes.  Each dataframe is of the same geographic area, although they are different images. For example, the top left image is a 1989 DOQ, the top right image is a reversed 1989 DOQ, the bottom left image is a 2012 DOQ, and the bottom right image is a reversed 2012 DOQ.   Is it possible to link the dataframes so that panning the image in one dataframe pans the images in all of the other dataframes (i.e. similar to how you can "Link Views" in Erdas Imagine)? Is this possible in QGIS? Launch app only if not already open Throughout Blade Runner we see Gaff (Edward James Olmos) making origami figures at various points in the movie. He makes a chicken, matchstick men and at the end of the film there is a unicorn waiting outside Deckard's apartment.    There is a   of  out there regarding the unicorn in particular, and how it indicates that Deckard is a replicant. I think an answer regarding the use of origami in general will be interesting new ground to cover.  Why origami? What does the origami represent in Blade Runner? During iPhone update to iOS 10.3.1, I was asked for my password using the correct machine name for my Mac mini. To be clear, the request was not for my iCloud password, my actual local user account password for macOS. This can also happen in the other direction - setting up a Mac may ask for verification for you to enter your iPhone / iPad passcode (and not your iCloud password)  I could not find any information about this kind of access. I was thinking it was security for iCloud and possibly related to two step authorization or two factor authorization. This is the first time I can think of that I entered a desktop password outside of that actual desktop.  I don't have a screen shot but I recall an implication that some files in my Mac are encrypted and need my password. '... need to enter the password for .'   Are there settings I can I control this assuming it's a legitimate part of iCloud setup process or iOS setup process? Objects stuck in solid mode? I can't figure out what is causing this I tried removing the materials for the objects as well as re-assigning new materials and flipping normals I don't know what is causing this issue for the model.  The head seems to be working like it should but the body doesn't turn white in textured mode or black in material mode. I'm using default blender render What does this notation mean? $f(x) \equiv A$? If $\lim_{x\rightarrow\infty}f(x) = A$, prove that $f(x)\equiv A$.  Any help would be appreciated! I just don't even understand the question. I have a large array in C (not C++ if that makes a difference). I want to initialize all members of the same value.  I could swear I once knew a simple way to do this. I could use memset() in my case, but isn't there a way to do this that is built right into the C syntax? What is the right first step to take when integrating $1/(2+ \sin x + \cos x)$? I want a hint on this following integral. I don't know the first step, do I do $u$-sub. or do I use trig. sub or something?  $$\int \frac{1}{2+ \sin x + \cos x} ~\mathrm{d}x$$ What's the downtime limit of a domain controller (DC)? On my VMware  environment there are 10 VMs running. One of the VMs is the domain controller (). The other VMs are configured with a static DHCP and DNS IP address in their network settings.  How long is the downtime limit of my domain controller? I have Opportunity-lookup field on Opportunity (self),  Scenario:   Opportunity A if select Opportunity B using lookup then Opportunity B's same lookup field automatically populate with Opportunity A.   I tried to achieve this using trigger - before insert/update but its failing as:  System.DmlException: Update failed.

Options to move the school rucksack during the trip Reset lightning:input textbox Field Value to Null I am trying to create a button which will update a field value to null (RESET it). However, it's not working and not even giving any error. So when I click on the button, nothing happens.  lc.cmp:  &lt;aura:attribute name="myObj" type="Account" default="{'SObject':'Account'}"/&gt; &lt;lightning:input type="text" name="accountPhn" label="Enter Account Phone" value="{!v.myObj.Name}"/&gt; &lt;lightning:button label="Reset" onclick="{!c.resetMe}"/&gt;   lc.js:  resetMe : function(component, event, helper) {         //alert("Called");         component.set("v.accountPhn","");     }   Appreciate help around this. Find three Poisson-distributed random variables, pairwise independent but not mutually independent Prove that $x^2 + y^2 = 3(z^2 + m^2)$ has no solutions in integer What is the difference between "var=${var:-word}" and "var=${var:=word}"? Why was my "shopping list" question closed? My question was closed for being a "shopping list question", even though it was very much related to the topic of the site. Why? Explicit norm on $\mathcal{C}^0(\mathbb{R},\mathbb{R})$ Do you know an explicit norm on $\mathcal{C}^0(\mathbb{R},\mathbb{R})$? Using the axiom of choice, every vector space admits a norm but have you an explicit formula on  $\mathcal{C}^0(\mathbb{R},\mathbb{R})$?  A related question is: Can we proved that $\mathcal{C}^0(\mathbb{R},\mathbb{R})$ has a norm without the axiom of choice?
