I know this question has been asked many times, but I could not find a good answer for my question, yet...  I wanted to develop my own thesis style i.e. \usepackage{harthesis}, which I did, but when I compile it, I got an error saying harthesis.sty is not found...  What is the easiest and best way to create your own thesis style? I am sure this question would be very helpful for many people.  These are part of my developed, but not limited to thesis styles:   \permanentaddress \examiners \convocation   and so on..  These were intended to be my title page and other university requirements before I even start writing my Intro..  Any suggestions?  Thanks.
What are some good tutorials on writing custom styles (classes) that clearly explain commands used and some of the features that TeX has to offer in the way of styles?
Homework question on whether two quotient spaces are homeomorphic Personal Hotspot not working over Wi-Fi on iOS 13 After upgrade to iOS 13 from 12.4, I noticed that personal hotspot isn't working anymore over Wi-Fi (via USB is ok).  Tested on two computers with Win7. The PC can connect to Wi-Fi, but no valid IP (IPv4) is assigned and no connection is working to internet. Using Nouns or Gerunds Could anyone explain when to use a noun or a gerund?  Are these sentences correct? What is the difference between usage of gerund and noun there?

Changing Date format and appending to original file I have file like this called a.txt:  [2016-03-30T04:51:51.599-04:00]!ER_DEV!Port_Conflict!/u05/app/ [2016-01-20T04:30:21.885-04:00]!ER_DEV!Port_Conflict!/u05/app/   I need to modify it so it looks like:    2016-03-30 04:51:51!ER_DEV!Port_Conflict!/u05/app/   2016-01-20 04:30:21!ER_DEV!Port_Conflict!/u05/app/   i already wrote a command to change [2016-03-30T04:51:51.599-04:00] to 2016-03-30 04:51:51 .but how to append the query output to original file.    awk -F'!'

Ice skater increase of energy This may be a very basic question but I am not seeing how it works. Consider the standard example of an ice skate rotating about his/her center of mass and pulling in his/her arms. The torque is zero so we have conservation of angular momentum. This implies that $\omega$ increases to keep $I\omega$ constant, but then $K_{rot}=\frac{1}{2}I\omega^2$ doesn't stay constant, it increases. This implies that there is work done, but what force is doing this work? I have a new laptop which I am setting up as dual boot Windows/Linux.    I would like to access files from both Ubuntu and Windows 7.  Should I create a separate NTFS partition? Network-wide HTTPS: It's time Modern Linux commands that parallel uuencode/uudecode functionality I need to get binary files into text format.  Years ago, I used uuencode/uudecode, and it was easy:  uuencode file.xls &gt; file.txt # Delete file.xls # Do whatever with file.txt # Now I need file.xls back uudecode file.txt &gt; file.xls   But uuencode/uudecode is not on my system, and as I look around, the yum/rpm process is ugly--this gives me the clue that maybe no one uses it any more and instead there is something more modern to do this.  I looked at xxd and hexdump but couldn't get them to do it.  Could just be dumb user issues.  What can I use on Linux to do this?  Would like it to be something that tends to be in the native install so I don't need to yum/rpm it if possible.  Just for your own understanding, what I'm specifically trying to do now is source control an *.xls file but the corporate tool doesn't allow *.xls in.  I respect that constraint normally, but in my context, an *.xls is a configuration table for my code so It is logically like source code, but the corporate SVN trigger is physical--if it's *.xls, it gets rejected, so I'll encode it and source control the *.txt file.  Thanks! Prove that $x^2 = - 1$ has no solution in $\mathbb{Z}$ I have this proposition to prove: The equation $x^2 = -1$ has no solution in $\mathbb Z$. I was told that this is an opportunity for a proof by contradiction. I have already proven that for $m \in\mathbb Z$, if $m \ne 0$ then $m^2 \in\mathbb N$. I have also proven that 1 is a natural number (hence, -1 isn't one).  Here is my strategy: assume that there is a solution. Hence $x^2$ has 3 options: \begin{align*} x^2 \in\mathbb N\\ -(x^2) \in\mathbb N\\ x^2 = 0 \end{align*}  Option 1 is not possible because -1 is not a natural number. Option 2 doesn't make sense because         -$\mathbb N \in \mathbb N$ and option 3 doesn't make sense either because $0 \ne -1$. What do you think? Thank you!    Here is a simpler strategy based on the comments below.  Proof: Assume that $x^2 = -1$ has a solution in $\mathbb Z$, then $x^2$ will either be $0$ or $\in\mathbb N$. However, $-1 \notin\mathbb N$ and $-1 \ne 0$. Hence, there is a contradiction. Here is how I have proven that $-1 \notin\mathbb N$: Let $m \in\mathbb N$. Hence:  \begin{align*} -m \notin\mathbb N\\ (-1)m \notin\mathbb N \end{align*}  If $-1 \in\mathbb N$, the product of $-1$ and $m$ should $\in\mathbb N$, which is not the case here. Hence, $-1 \notin\mathbb N$. First post and late answer review queues always empty? Persist sort/filter selections Playing a remote movie on the remote computer I have two computers (a desktop and a laptop) running linux connected to my local area network. I like to ssh from my laptop over to my desktop and run programs there, and sometimes listen to music on my desktop, which is connected to my stereo system. Lately, I've been wanting to play movies on the desktop and desktop screen, but cue them from my laptop across the room.   Unfortunately, I cannot play a movie in the current X session running on my Desktop on from my laptop. What is odd about this is that I can listen to the audio coming from the speakers that are hooked up to my desktop, by playing the audio files over ssh! This tells me that there must be a way to send the movie to that Xsession, from the ssh shell that I am connected to.  Does anyone have any ideas about this? I am getting these warnings every time I update my initramfs image(-s) with  on my Dell PowerEdge T20 server running    10.0. Is there a fix?

It is the analog to the mommy mommy flag (which my 1.5-year-old child raises quite frequently). It provides no real clue as to what the flagger really wants us to do with the post.   Does she want us to close the question?  Does she want us to edit it into shape?  Does she want us to delete the question?  Does she want us to ban the user?  Does she want us to jump around and have a party?    Should we get rid of this flag reason?   Is it just me? Should and can we replace it with something better?     EDIT I accepted Jeff's answer. The tougher wording has heavily decreased the amount of very low quality flags. We now see only about 25% of the amount we used to and they are usually valid. Additionally, we now only allow very low quality on posts with a score of 0 or lower. What are reserved filenames for various platforms? What is so special about speed of light in vacuum? I will try to be as explanatory as possible with my question. Please also note that I have done my share of googling and I am looking for simple language preferable with some example so that I can get some insight in this subject.  My question is what is so special about $c$? Why only $c$. Its like chicken and egg puzzle for me. Does Einstein reached to $c$ observing light or does he got to light using some number which turned out equal to $c$.   Why is $c$ not relative. If something has zero rest mass like a photon why they only travel at $c$ in vacuum and not with $c+1$ or $c-1$? Possible (but not serious) glitch in close/reopen I just had one of my questions closed. (Hey - it happens to everyone) When I clicked on reopen - lo and behold - it worked. I cast a reopen vote!  Is this a glitch? I know we need 4 more votes anyway but still...  And no  tag please :) Caps-lock remapping stops working
