Not able to apply macbuntu theme I just started using Ubuntu so please give me an explained answer.  I was trying to install macbuntu theme in my Ubuntu 16.10. I did the first step which was   sudo add-apt-repository ppa:noobslab/macbuntu   This step worked fine. Next when I did,  sudo apt-get update   I got the error  W: The repository 'http://ppa.launchpad.net/docky-core/stable/ubuntu yakkety Release' does not have a Release file. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use. N: See apt-secure(8) manpage for repository creation and user configuration details. E: Failed to fetch http://ppa.launchpad.net/docky-core/stable/ubuntu/dists/yakkety/main/binary-amd64/Packages  404  Not Found E: Some index files failed to download. They have been ignored, or old ones used instead.   These are just the last few lines which gives the error.  How do I solve this?

How can I fix a 404 Error when using a PPA or updating my package lists? PPA seems to be constantly offline. Whenever I use sudo apt-get update, this error is shown:  W: Failed to fetch http://ppa.launchpad.net/ 404  Not Found   How do I fix these errors?

I am struggling with whether I should go for logit or arcsine transformation. One source says that arcsine transformation should not be used . On the other hand, I several zero counts. With logit transformation values 0 and 1 are mapped to infinity, and according to another source I should go with arcsine transformation . Furthermore, I found another study close to my topic in which they used arcsine transformation. The default in R with metaprop function is logit.   Which one I should go with my data? How do I update the GUI from another thread? Nautilus 3.6 doesn't have a status bar? In 12.04, Nautilus showed the amount of remaining space in the status bar , but as of 13.04 the status bar is gone.  gsettings set org.gnome.nautilus.window-state start-with-status-bar true   turned out "no such key".  Is there any way to bring back the status bar? How can I view and examine the Android log? Should I upgrade to the "mainline" kernels? Newer "mainline" versions of the kernel are available from the , e.g. 3.4 and 3.5, while Ubuntu 12.04 is on 3.2.   What are the mainline kernels? Are they better than my existing kernel? What are the pros and cons of upgrading to a mainline kernel? Will I easily be able to go back? What was Natsume hiding in her closet in episode 11?

Algebraic closure of $\mathbb F_p$ Consider a sequence of $n$ Bernoulli trials with $P(\text{success})=p$. Let $X_i$ and $X_j$ be indicator variables of the number of "success" in $i$th and $j$th runs. Given the total number of success was $m$, $m&lt;n$. I am asked to compute the correlation coefficient for $X_i$ and $X_j$.  Now I know the formula for correlation coefficient, but to compute the co-variance I will need to find $E(X_i)$ and $E(X_j)$ first. By definition does $E(X_i)=p_i$ and $E(X_j)=p_j$? I feel this seems a bit too easy but I can't see whats wrong with it. \nameref breaks for star versions of section/paragraph when titlesec is loaded \nameref breaks for the star versions of section, paragraph when titlesec is loaded. I have a document that numbers paragraphs by default, but I have a few I do not want to number but would like to refer to. These are marked with \paragraph*, however, if the titlesec package is loaded at the same time, it causes nameref to display an empty string (the link box of hyperref is still visible).  MWE:  \documentclass[12pt]{article} \usepackage[sf]{titlesec} %comment this out and it works fine. \usepackage{hyperref} \begin{document} \section{Sections} \label{sec} This is \nameref{sec} \paragraph{A named Paragraph} \label{par} This is \nameref{par} \paragraph*{A starred named Paragraph} \label{par:star} This is \nameref{par:star} \end{document}   I suspect titlesec causes this defect for ALL star variants of sectioning commands but have not tested this. For me only paragraph* is relevant however a fix for all variants would be the best.  I have a hunch it might be related to this:  however this happens to go way beyond my latex knowledge and is just "magic" for me. Recently I've been messing around with making a few minigames, and have used a few plugins to help make it easier to create and run them. However, a newer one I'm making requires me to use the /summon command in order to spawn zombies. However, no matter what I put in, I can't spawn hostile mobs. All other entities still spawn perfectly fine. Strangely, the /spawnmob command which comes with Essentials can summon hostile mobs fine. I would rather use /summon since it's more customizable though. Here's a list of plugins I have installed.

In the case of a non-inverting amplifier, if I DC couple the input signal with a capacitor only, \$C_1\$ (i.e. no resistor to ground), sources (as well as an experiment in the lab) show me that the op amp input will be saturated as the input bias current deposits charges on the terminal without having a return path to ground. This is solved by using connecting a resistor (\$R_1\$, as shown in the image below) to ground to create the return path. [The image is reproduced from an answer by "Neil_UK" on one of my previous questions, thanks Neil!]    My questions:   1) How is the input bias current able to continuously deposit charges and saturate the input if I don't use the resistor? The resistor should not allow the DC bias current through, so where is this current flowing from/into?  2) Why is this not a problem for the feedback path to the "-" terminal? There is no resistor to ground in that case, and capacitor \$C_2\$ seems to be causing no issues. The PDFs I've been reading suggest that the feedback behaves similar to when I have a resistor to ground by acting as the return path, how is this? Why is energy in a wave proportional to amplitude squared? Is gravity just electromagnetic attraction? Recently, I  was pondering over the thought that is most of the elementary particles have intrinsic magnetism, then can gravity be just a weaker form of electromagnetic attraction? But decided the idea was silly.    But I then googled it and found  article. Is this idea really compatible with other theories as the article mentions? Is there any chance of this proposition being true? My MacBook Pro has a flashing question mark in a folder against a grey background My MacBook Pro shows a grey screen with a flashing question mark in a folder. I tried connecting it to an older MacBook using firewire cable. I restarted the Macbook Pro in Target Mode. Now I see Thunderbolt and Firewire icons flashing and moving in a grey background.
