If I play  (and we know he comes into play tapped) and have a  or something out to untap him, am I prevented from sacrificing the two islands and attacking the turn he came into play? In other words, if a creature comes into play tapped and you untap it, does it still have summoning sickness preventing it from attacking?
Note: this is intended to be a canonical question about summoning sickness.  "Summoning sickness", broadly, is the rule that stops you from attacking or paying {T} costs with a creature that you just played. But how exactly does it work? How does it interact with other rules and effects?  For example, if I'm trying to figure out how a creature is affected:   Does the status matter (tapped/untapped, face down/face up, etc.)? What if it came into play, but I didn't cast it? What if it's a token? What if it was on the battlefield when my turn started, but it wasn't a creature? What if it stops being a creature? What if it's a creature and also another card type? What if it's a double-faced card that just transformed? What if it changes control? What if it's a copy of another creature? Which of the creature's activated abilities can I use? Are any of its other abilities affected? Can I tap the creature to pay a cost that is not a {T} cost?   (These examples are primarily taken from questions about summoning sickness that have already been asked on the site)
Change folder permissions and ownership I would like the user to have full rights on this folder (as well as all sub-directories and files in it):  ~/.blabla   currently owned by root.

Can we get some consensus on what flag to use for link only answers? Related:  (not a dupe, that's a feature request and was closed as a dupe of another one)        (old) post does indeed say that Link-only answers can be flagged as NAA, but there are a lot of posts like  which define Not An Answer is a way that it doesn't apply to link-only answers.

Restore default apt repositories in sources.list from command line I am looking for the best method to restore /etc/apt/sources.list to default from the command line.

Solutions Ruled Out  Before you mark this as a duplicate, note that I have reviewed  already. It is only applicable if you have the Ubuntu GUI available. This question is specific to the command line.  I have also reviewed  where the accepted solution is someone pasted the contents of their sources.list file. This is not an appropriate way to restore the file as the intentions of the person providing the file contents cannot be verified and the file is subject to change with new releases.

Google Analytics - Traffic Source - Search engine - (Not Provided) I am using Google Analytics, now here when I go to "Traffic Source Overview" under that it shows Keyword as "(Not provided)" which is almost 40% of my traffic source. Now more than 90% of search engine traffic is from Google and still out of that for more than 40% of keywords are "(Not provided)".  Can anyone explain me what is going wrong here or how can I get that data? Because that comes as 1st option and is biggest keyword in the list. Will that be some crawler or secure google search? I do not understand how dummy variables work in math.   Suppose we have:  $$I_1 = \int_{0}^{\infty} e^{-x^2} dx$$  How is this equivalent to:  $$I_2 = \int_{0}^{\infty} e^{-y^2} dy$$  How does this dummy variable system work?   Since $y$ is the dependent variable for $I_1$ How can $y$ itself be and independent variable for $I_2$  ??  Thanks!

Connecting desktop computer to the internet through laptop wifi Due to some home network complications I have had to move my router to a seperate part of the house, therefore the wired network I had set up can no longer work. Before I find the time to go out and buy a Wifi adapter for my desktop PC, I have a laptop that uses a built in Wifi card to connect to my router and this can connect to the internet, and I was wondering if I could somehow access the internet on my desktop PC via my laptop.  I'm hoping for a not-so-complex solution as this will only be set up for a few days, but it is quite vital that my desktop computer gets internet access.  Does anyone have experience in this sort of thing and can help me out? Thanks. Totally disconnected space that is not $T_2$ Suppose $f(x)$ is linear i.e. $f(x + y) = f(x) +f(y) $ and monotone on $[-\infty, +\infty]$, then $f(x) = ax$, a real.
