I currently have libflashplayer.so in the mozilla plugin folder, but still flash is not working with Firefox 49.0 under Ubuntu 14.04?  Any assistance would be greatly appreciated.  Been at this for a look time.  Thanks
I know, it's been asked before but I couldn't really get a satisfying answer for some details/backgrounds and I guess it's an important question for many.    Some application seem only to be running with Adobe Flash 15 (or at least I know it does, because I have that version on my Windows Partition).  The official Adobe website says:     NOTE: Adobe Flash Player 11.2 will be the last version to target Linux as a supported platform. Adobe will continue to provide security backports to Flash Player 11.2 for Linux.   Some search on the web like "Ubuntu Adobe Flash 15" or similar does not return any good websites.  I found something that says   (using a "pepper-based version"), and  .   Is it impossible to use this for Firefox too? Would it be a privacy risk?  Are there no alternative projects (I know it's closed source but there are so many so very bright people out there using something similar to wine but just for the plugin....)?  How about the Mac-Version? Shouldn't someone be able to port that one to Linux?
Why is integration the inverse of differentiation Why is integration the inverse of differentiation, I mean why do I get the same function when I integrate and then differentiate the result? Suppose $f:\mathbb{R}\to\mathbb{R}$ is Borel measurable. I want to show that $\displaystyle \int_a^b f(x)\mathrm dx=0$ for all $-\infty&lt;a&lt;b&lt;\infty$ with $a$ and $b$ rational implies that $f=0$ a.e. I'm really not sure how to approach this problem; any help would be welcome. Quotient rings of Gaussian integers I used this isomorphism today but now I'm having trouble justifying it. The norm function isn't additive so I can't come up with a ring isomorphism to prove the following:     For any $\,a+bi\in\Bbb Z[i],\,\gcd(a,b)=1$, we have a ring isomorphism   $$\Bbb Z[i]/\langle a+bi\rangle\,\cong\Bbb Z/(a^2+b^2)\Bbb Z=:\Bbb Z_{a^2+b^2}.$$   Could someone show me an isomorphism between these rings to prove this? Let's say I have  on the board. He is a 2/2 that says:  Whenever another creature enters the battlefield under your control, creatures you control get +1/+1 until end of turn.  I play a . It says:  Put three 1/1 red Human creature tokens with haste onto the battlefield. Sacrifice those tokens at the beginning of the next end step.  The sacrifice portion is not important to this question. What is important is how these two cards interact with each other. Playing this card in my first main phase, assuming no counters or other shenanigans by my opponent, I will have my Commander and 3 tokens on the battlefield. What will happen in terms of the power/toughness of my tokens and Commander? Option A The tokens will be 1/1 each. They don't see each other come in at all. The Commander is 3/3, as one &quot;enter the battlefield&quot; trigger happens. Option B The tokens will be 1/1. They don't see each other come in at all, because they weren't on the battlefield to see any of the triggers. The Commander is 5/5, as he saw three &quot;enter the battlefield&quot; triggers occur. Option C The tokens will all be different, with one being 3/3 as he saw the other two come in, one being 2/2 as he saw only the last one come in, and 1/1 as the last one saw none come in. Option D The tokens will all be 4/4, as three creatures entered the battlefield this turn. I am obviously hoping for this option. It may be supported by a ruling on Goldnight Commander that says, emphasis mine:  The creature that entered the battlefield will also get +1/+1 until end of turn if it's still on the battlefield when the ability resolves.  The key being the ability resolving. So my thought is thus:  Thatcher Revolt goes on the stack. Thatcher Revolt resolves, and three separate &quot;enter the battlefield&quot; triggers go on the stack as the three humans enter the battlefield as 1/1. The last (it is a stack) &quot;etb&quot; trigger resolves. This puts an ability from Goldnight Commander on the stack. This resolves and the humans are now all 2/2. The next &quot;etb&quot; trigger resolves. This puts a new ability from Commander on the stack, and resolves with the humans being 3/3. The first &quot;etb&quot; trigger finally resolves, puts a Command ability on the stack, which resolves putting the humans at their final state of 4/4.  Option E The tokens will all be 2/2.  Thatcher Revolt goes on the stack. Thatcher Revolt resolves, and one single &quot;enter the battlefield&quot; trigger goes on the stack. The &quot;etb&quot; trigger resolves. This puts an ability from Goldnight Commander on the stack. This resolves and the humans are now all 2/2.  I would really like to have a complete understanding both of the result and how this result is calculated by the game engine. Two ethernet ports on motherboard. How can I get double the bandwidth? Direct Question:  My evga classified motherboard has two ethernet ports.  I want to use them simultaneously to improve the speed of a remote connection.  (Yay for programming remotely).

Is there a package I need to install to bond the two channels.  Background: I do a lot of remote computing both from home to office and office to home.  But (to take my ISP out of the equation), let's frame the question as if I'm really just interested in maximizing the file transfer rate between two computers on the same (local) network.  Both boxes have dual ethernet motherboards.  Using a simple Linksys WRT54GS as a 5 port switch (ignore wireless and isp) -- how do I maximize the transfer rates between the computers?  Please Note: I'm not interested in load balancing -- Correct me if I'm wrong, but I want to bond the two channels together so that the box appears as if it has one connection that's twice as fast.

How can I show that if the second fundamental form of a surface is identically equal to zero, then the surface is a plane? This is my question:  Let P be a plane considered as a surface in 3-space. Show that its second fundamental form is zero. Conversely, show that if the second fundamental form of a surface is identically zero then the surface is a plane.  So far I have that the general equation of the plane is $$ax+by+cz+d=0.$$ Then $$M(u,v)=(u,v,\alpha u + \beta v + \gamma),$$ where $a,b,c,d,\alpha,\beta, \gamma$ are all constants and $c\not=0$. Then $M_u=(1,0,\alpha)$ and $M_v=(0,1,\beta)$. I know that $\vec{n} =\frac{M_u \times M_v}{|M_u \times M_v|}$ which gives $$ \vec{n}=\frac{(-\alpha,-\beta, 1)}{\sqrt{\alpha^2+\beta^2+1}}.$$ Hence, the unit norm is a constant. $$ M_{uu}=M_{uv}=M_{vv}=0$$ Hence $l=m=n=0$, so the second fundamental form is $$ ldu^2+mdudv+ndv^2=0.$$  Now I need to show the converse, but I don't know how. Please help :) I've followed this tutorial to install Ubuntu 15.10:    After restarting my computer I got to the grub menu and chose Ubuntu. Shortly after that I got this error:  /run/lvm/lvmetad.socket: connect failed: No such file or directory WARNING: Failed to connect to lvmetad. Falling back to internal scanning.   These messages keep adding up on a black screen every second. After a while,  I get access to the initramfs ash console.  what am I doing wrong? Hibernate is disabled, hiberfil.sys gets recreated at each boot I have Windows 7 running on a small (40GB) partition, with 4GB ram. This means that the hiberfil.sys file created by Hibernate takes up a significant portion of the available diskspace. I would like to remove it.  I am aware that I can disable Hibernate and remove hiberfil.sys by entering powercfg -h off in an elevated command prompt. This works -- the file is immediately removed, and after doing so, the HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\HibernateEnabled key is (correctly) set to 0.  However, the next time I reboot the PC, hiberfil.sys returns from the dead, Hibernate is reenabled, and that registry key has returned to 1.  I'm pretty much at my wits' end with this. Almost everything I can find online related to removing the hiberfil.sys file simply suggests using powercfg to turn off hibernation, and that appears to work for just about everyone. But it just keeps coming back for me! (Like a vampire, sucking up my disk space.) I did find  from someone who seems to have had the same issue, but none of the suggestions there worked for the original poster (or for me). Still, I have tried everything listed there, including:   Disabling hybrid sleep Disabling Hibernate through the command prompt, through the Power Options GUI, and through both (in both orders) Manually changing the HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\HibernateEnabled key Pretty much everything else I can think of!   I do want to reiterate that I have no problem removing the file -- that works great. It just comes back after every reboot. I'm about ready to throw in the towel and just run a script on login to disable Hibernate each time, even though that seems like a crazily hacky "solution" . . . but I was hoping someone here could suggest something else, first.

I have seen numerous references on the internet of people describing SHA-256 as generating an "almost unique" hash.  . there are more.  Is there some mathematical basis to the almost uniqueness? I would have thought that as SHA-256 is an evenly-distibuted (?) hash algorithm which can accept any message (infinitely many) as an input and produces a fixed length (finite) hash - then there will in fact be an infinite number of each possible output - which I would think hardly qualifies as "almost unique".  Is there a basis for this statement? Find the inverse of a Trig Matrix I don't have a clue of what's going on. We haven't learn this in class so I need all the help possible.
