What's the diffeernce between super(SomeClass, self).__init__() AND super(SomeClass, self).__init__(*args, **kwargs)? The first one initializes the constructor of the parent, but what about the second one?
In the following method definitions, what does the * and ** do for param2?  def foo(param1, *param2): def bar(param1, **param2):
Conky Widgets are Opening in their Own Windows I just upgraded to 16.04 and I'm getting all my customization set up again, but it seems that most Conky widgets are opening in their own window, instead of just appearing on the Desktop; although some are working correctly.  For example:  LSD (working properly):    Seamod (not working, opening in own window):    Since it's not affecting every single widget, I assume it could be an issue with the conkyrc with the widgets that aren't working, but this also never happened in 14.04 so I wasn't sure if maybe there was some compatibility issue in 16.04. My Google-fu has failed me in finding a solution.  If anyone can point me in the right direction, it would be much appreciated! :) Let $P(x)$ be a degree $n$ polynomial with distinct roots $r_1, r_2, \cdots r_n$. Prove that   $$\displaystyle\sum_{i=1}^{n}\frac{P''(r_i)}{P'(r_i)}=0$$  My proof: We can equivalently rewrite the polynomial as $(x-r_1)(x-r_2)\cdots(x-r_n)$ and if we plug in the roots in the polynomial, we get that all of them are equal to $0$ so their first derivatives are equal to $1$ and then their second derivatives are equal to $0$ which means that all quotients are equal to $0$ and there for the sum is as well, $Q.E.D$  Don't show the solution please, but if you have a hint, feel free. Thank you. In the US, it is common to use the idiomatic expression "knock on wood" to keep "a good thing going."  Is it the same in the UK, or do they use a different idiomatic expression? In classic OLS regression it is well-known that $(\mathbf{I}-\mathbf{H})\mathbf{y}=\mathbf{r}$, where $\mathbf{I}$ is the identity matrix, $\mathbf{H}$ is the , $\mathbf{y}$ is the vector of response (dependent) values, and $\mathbf{r}$ is the vector of residuals.  My question is whether the scalar $\mathbf{y}^T(\mathbf{I}-\mathbf{H})\mathbf{y}=\mathbf{y}^T\mathbf{r}=\mathbf{y}^T\mathbf{y}-\mathbf{y}^T\mathbf{\hat{y}}$ has some meaningful interpretation. How to Expand , Resize "extended partition"? How do you use plural or singular form of an adjective? I recently obtained a Seagate Expansion 3TB external harddrive. I'm trying to copy over all of my stuff to prepare for reformatting and installing a new OS. A handful of my mp3s did not transfer when I was doing my music folder. I checked them after the fact and the ORIGINAL files became corrupted somehow. I am certain of at least a few that were not corrupted in anyway before doing this. Every now and then during my transfer I got  There was an error copying the file into /media/***/Seagate Expansion Drive. Error splicing file: Input/output error   Each of these files that I check after are corrupted at some point in the duration and will not play. Why did this happen and what can I do to fix it? How to get the ASCII value of a character I often cook fries in a skillet. I put about 1/4 cup vegetable oil into a large skillet and heat on high, then I toss in some frozen fries.   As soon as I toss them in there is an explosion of grease that makes a huge mess. After it simmers down though, I can cook the fries without spilling anymore grease.  Is there anyway to avoid the initial uproar? How to efficiently find positions of duplicates?

What is the difference between the displace socket and a bump map? Aside from the fact that you can control the bump mapping per shader with a bump node, are there any differences between these materials?      As far  as I can tell, they are the same. Is the displacement socket just a convenience thing? Is there a performance advantage? Why not to extend the set of natural numbers to make it closed under division by zero? We add negative numbers and zero to natural sequence to make it closed under subtraction, the same thing happens with division (rational numbers) and root of -1 (complex numbers).  Why this trick isn't performed with division by zero? Is there a way in blender or an addon that allows me to select a bunch of faces (or verts) and evenly distributes (or relaxes) them into quads clean quads.  Without screwing up the vert ID/order.  Edit: I would like to have the shapes of my quads to turn into perfect squares while maintaining the volume of the object and the vertex order. How to change the forgotten root password? I forgot my root password...actually I think I know what it is because it is the same password I have for pretty much everything but in the Terminal in tell me "Sorry, try again." Is there a way to reset the password? If so how? Need help identifying the fantasy book about a portal to a fantasy land in the basement of a house I can't remember any names of characters or locations where the story took place but I do remember the basic plot of this early 90's novel; a human man inherits his father's house. In the basement there is a doorway to a fantastic land where adventure ensues. He fights elves and wins their deadly elf swords which he buries under concrete at the end of the novel (because if you don't get rid of them they will come back and get you).  At the end of the novel he must remake the world in his own imagination, turning the tough Elf King into a cobbler and making Jesse Jackson President. I have been looking high and low and have drawn a blank.  Any help would be appreciated. Thanks! Honey changing into unusable, hardened clump I buy raw, unfiltered honey from the grocery store in jars sold/packed directly by the farmer. When I had used the last jar to about half, I noticed the honey beginning to dry(crystalize?) to the point where I couldn't use the honey around these spots.  Not too long after this, the entire jar had crystallized into a block of unusable hard stuff.   I didn't do anything differently with this jar than the last jar, but only now am I having the issue. My question(s):   Why is the honey crystallizing, and why so rapidly?   1) Is the honey unusable at this point?  2) Should I store the honey differently after purchasing it(move from jar to other container)?  3) I've never seen this happen to the filtered, strained(fake) honey from the store, so what causes this to happen in the raw and unfiltered form?
