I am trying to install some necessary packages but always get the Error "not a local package repository" as you see in picture ?  What can I do?  Thank you Very Much
I used MiKTeX 2.9 on windows. I have downloaded a package I want to install from the internet (manually, not through MiKTeX). The archive (*.lmza) containing the package was saved to a directory on my C:\ drive. Through MikTeX -> Maintenance -> Settings -> Packages -> Change... I can select the directory in which I have saved the archive containing the package. However, if I choose Packages shall be installed from a directory and choose the location of the package, I get this error message: C:\my\package\is\here does not seem to be a local package repository. What does it take for a directory/folder to become a local package repository?
I hope this qualifies as a programming question, as in any programming tutorial, you eventually come across 'foo' in the code examples. (yeah, right?)  what does 'foo' really mean?  If it is meant to mean nothing, when did it begin to be used so? How can I add the session name to my screen status display? This is my current .screenrc files which is mostly copied from the link in the code  #First iteration 2014-09-06, not quite sure of stuff to add # got a fancy hardstatus line noted below hardstatus on hardstatus alwayslastline # hardstatus string "%w"  # blagged this hardstatus like from https://bbs.archlinux.org/viewtopic.php?id=55618, not quite sure what it does hardstatus string '%{= kG}%{C}Screen: %{c}%{= kG}[%= %{= kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{C} %d-%m %{W}%c %{g}]'   I now want the session name to appear in it as well, and the one I have settled on is from this answer -   The solution runs along these line:  hardstatus string '%H:%`' backtick 0 30 30 sh -c 'screen -ls | grep --color=no -o "$PPID[^[:space:]]*"'   It is an area I am not familiar with and I wonder how the backtick command fits in it, ie whether it is a screen command at all. For example, if the ex-dividend date is next Monday, and I buy the stock on next Monday, would I get the dividend? Or would the person who sold the stock to me get the dividend? How does deleting work? What can cause a post to be deleted, and what does that actually mean? What are the criteria for deletion? Since there are gravitational lenses, are there gravitational mirrors? Gravitational lensing is an observed phenomenon. Can one have a gravitational mirror?   A slightly unrelated question: Can gravitational waves be reflected? How to add "Refresh" option to right click menu in Lubuntu? I have many users at the place I work, expressing the notion of switching to Ubuntu.  Most of them, for whatever weird reason wanting to know if its possible to have refresh added when you right click on the desktop.   Is that possible? How to get less spacing in math mode LaTeX commands like this:  Here again, four different simulations are run on networks of size  $C^{G} = 25 \times\ 25 = 625$, $C^{G} = 50 \times\ 50 = 2500$, $C^{G} = 250 \times\ 250 = 62500$, and $C^{G} = 500 \times\ 500 = 250000$...   When compiled generate the following:    The spacing in math mode really irritates me. There's too much white space around the equal sign, and the multiplication sign has more right padding than left padding. Is there any way to reduce this spacing? Change rep required to downvote on MSE To make your opinion known on MSE you need both up and downvotes. Given at the moment you need 125 rep to downvote on this site, the voting patterns will be skewed positive because not everyone is active on the site.   This is to be expected for regular Stack Exchange sites as you are expected to be involved in the community before you are deemed knowledgeable enough to be part of the community voice. However, MSE is different because you are voting for the entirety of the Stack Exchange network and you shouldn't need to be active on MSE itself to have a voice on changes to the entire network.  This is especially important for questions like  because it will effect every network to do with coding at all. This was brought up in .  I would suggest reducing the rep required to downvote on MSE down to 100 (or 101) rep. This is the amount you get for the site association bonus. This is given once you achieve 200 rep on any network site and shows that you are active in at least one community. I think this would be the perfect use of the association bonus in showing that you are a member of the Stack Exchange community. Removing leading zeroes from a field in a SQL statement I am working on a SQL query that reads from a SQLServer database to produce an extract file. One of the  requirements to remove the leading zeroes from a particular field, which is a simple VARCHAR(10) field. So, for example, if the field contains '00001A', the SELECT statement needs to return the data as '1A'.  Is there a way in SQL to easily remove the leading zeroes in this way? I know there is an RTRIM function, but this seems only to remove spaces. Highest power of a prime $p$ dividing $N!$ How does one find the highest power of a prime $p$ that divides $N!$ and other related products?  Related question: How many zeros are there at the end of $N!$?    This is being done to reduce abstract duplicates.

First I want to increase the size of a GameObject and then delay for 0.1s before returning it back to its original size. However, when I try using StartCoroutine(), it keeps giving me the error :  An object reference is required to access not-static members   even though I made my Delay() function static. Can somebody please tell me what I'm doing wrong?  public static void MoveSelected(int choice) {     GameObject rock1 = GameObject.Find("Rock1");     GameObject paper1 = GameObject.Find("Paper1");     GameObject scissors1 = GameObject.Find("Scissors1");      Vector3 scl;      if (choice == 1)     {         scl = rock1.transform.localScale;         scl.x *= 1.1f;         scl.y *= 1.1f;         rock1.transform.localScale = scl;          StartCoroutine(Delay());          scl.x /= 1.1f;         scl.y /= 1.1f;         rock1.transform.localScale = scl;     }     else if (choice == 2)     {         scl = paper1.transform.localScale;         scl.x *= 1.1f;         scl.y *= 1.1f;         paper1.transform.localScale = scl;          StartCoroutine(Delay());          scl.x /= 1.1f;         scl.y /= 1.1f;         rock1.transform.localScale = scl;     }     else if (choice == 3)     {         scl = scissors1.transform.localScale;         scl.x *= 1.1f;         scl.y *= 1.1f;         scissors1.transform.localScale = scl;          StartCoroutine(Delay());          scl.x /= 1.1f;         scl.y /= 1.1f;         rock1.transform.localScale = scl;     }  }  static IEnumerator Delay() {     yield return new WaitForSeconds(0.1f); } What is the meaning of the integral of position? Jerk, $j(t)=\dddot x(t)$, acceleration, $a(t)=\ddot x(t)$ and velocity, $v(t)=\dot x(t)$ are derivatives of position, $x(t)$. What is the meaning of the integral of position?  For example, one could write  $$\int x \mathrm{d}t = \int x \frac{\mathrm{d}t}{\mathrm{d}x}\mathrm{d}x = \int x\frac{1}{v} \mathrm{d}x$$  which reminds the equation for . Does a Vietnamese citizen need a transit visa for South Korea? I am a Vietnamese passport holder. I'm going back to Viet Nam from Montreal this December, and I will transit at Incheon Airport for a few hours. Do I need a Korean visa just for transiting, either from Montreal to Hanoi or from Hanoi back to Montreal? Could gravity accelerate light? Graphical interface for generating presentation slides Is there a good graphical interface, similar to PowerPoint or LibreOffice Impress, for generating presentation slides?  When writing documents I prefer to write my text and LaTeX-markups using a text-editor and not using a graphical tool like LyX. However, in the case of presentation slides I want to see the layout and to have the ability to immediately see what you get e.g. by moving a picture with arrow keys.  ADDITION: The background to my question is as follows. I have used PowerPoint for more than a decade and like to use a WYSIWYG tool when making presentation slides. However, I can not use PowerPoint on my current computer and I think the output from LibreOffice Impress is inferior. As a long-time user of LaTeX, I have considered using SliTeX or Beamer but unfortunately I do not like the way of working. The end result is of course superior, but I found it very time-consuming and tiresome to e.g. adjust the position and size of pictures. Connected to wifi successfully, but no internet connection I'm a relatively new macOS user. Let me try to describe the problem I'm facing as succinctly as possible  Just this morning, when I'm unable to get any internet connection even though WiFi is connected (full strength). All my other devices has no issues when connected to the same network (it's my home network)  I've logged into the router, and checked, there are no blacklisted IP/MAC addresses.  Additional information   I'm using a tMBP 15" for over a year I've had no issues with any WiFi connectivity to my home network before today. ping from terminal doesn't work as well. I'm able to connect to my phone's hotspot, and get internet from my MBP.  I have bootcamp set up. When I boot into Windows, I'm able to get internet access through my home WiFi   How can I troubleshoot this to get to the root cause of the problem? What are the options for managing multiple Ubuntu installations together and keeping them in same state What is different about the Mac ISO image? I know that if you held an infrared remote in front of a digital camera, it'll flash a blue/purplish light when you press the buttons. Why?    (Image by  .)
