I'm trying to automatically mount a NAS drive on start. The command I'm using to manually mount it is:  sudo mount -t nfs 192.168.1.88:/NAS /media/nas   This works fine. This is what I'm putting in my fstab file which isn't working:  //192.168.1.57/nas /media/nas nas _netdev,auto 0 0   No doubt a basic error but my googling has failed me. Thanks very much.
I am trying to auto-mount my NFS drives, but it doesn't work too well sadly.  What does work is mounting from CLI:  me@client:/$ sudo mount 192.168.178.4:/mountdir /mnt/mountdir me@client:/$ mount -t nfs 192.168.178.4:/mountdir on /mnt/mountdir type nfs (rw,addr=192.168.178.4)   when I try to add mountdir in the fstab, I cannot mount it due to "protocol not supported" (which seems strange as I can mount it)  $ sudo mount films_d3 mount.nfs: Protocol not supported   So there might be something wrong with my fstab entry. This is my current entry:  192.168.178.4:/mountdir /mnt/mountdir  nfs auto,_netdev,noatime,nolock,bg,nfsvers=4,intr,tcp,actimeo=1800 0 0   During startup I also get this error twice: I was trying to fix the mount-from-fstab first, then worry about that, but nevertheless this might be a different problem:  init: idmapd-mounting (/mnt/kazemat/films_d3) main process (445) killed by TERM signal   This seems to be before the eth0 is initialised, while I thought the "_netdev" option would make the entry wait for the network to be up?  can anywone see the mistake in my fstab entry?
Why are empty and non empty TikZ matrix cells not equally placed? I wanted to draw an almost empty matrix of nodes with TikZ similar to the left most one below. All nodes would have same size (through minimum width and minimum height) and no separation between columns and rows. But when I include a text which needs two lines I obtain the central matrix and, if the text just needs one line the right most one. I don't know what's wrong. Do you? I'm using CVS version of TikZ.  \documentclass[tikz,border=2mm]{standalone} \usetikzlibrary{matrix}  \tikzset{ proces/.style={draw, minimum height=15mm, minimum width=2cm, outer sep=0pt, text width=1.5cm, align=center} }  \begin{document} \begin{tikzpicture}  \matrix (A) [matrix of nodes,nodes=proces,nodes in empty cells] {  &amp; \\  &amp; \\ };  \begin{scope}[xshift=4.5cm] \matrix (A) [matrix of nodes,nodes=proces,nodes in empty cells] {  &amp; OOO OOO \\  &amp; \\ }; \end{scope}  \begin{scope}[xshift=9cm] \matrix (B) [matrix of nodes,nodes=proces,nodes in empty cells] {  &amp; A \\  &amp; \\ }; \end{scope}  \end{tikzpicture} \end{document} A secant inequality for convex functions Why does the Community User reject / approve edits? Einstein equation  where $E$ is energy, $m$ mass, and $c$ the speed of light in vacuum.

Whenever my cheese gets too old and has a bit of blue/white mold on the side, I'm not sure whether I should throw it completely out or not. Is it safe to eat if I cut off the edge? Should I cut a bit off of all the sides just to be safe?  I'm particularly interested in the answer for cheddar cheese, but answers about other cheese are welcome. I can't seem to find a story related to mine so here it is.  I am 25 and a German citizen. In 1998 when I was 7 years old my family moved to the states and we stayed until early 2002 and left voluntarily. Basically we overstayed. I am aware that my parents had the ten year ban and since I was a minor at the time of our overstay I did not receive such ban.  Ever since 2002 I have not attempted to go back to the USA for any reason. However now that I am older I would like to go back for vacation and stay for a short period of time (one month) during my christmas break.  I've lived in Germany since leaving, have a great job, enough money in the bank account. My whole life is here and I have no intention on moving anywhere else.  After reading a bunch of stories online I have decided to apply for a B2 visa to be on the safe side but I was curious about the ESTA approval. For the last question. 8) Have you ever stayed in the United States longer than the admission period granted to you by the U.S. government?   I should put yes but is it a no if I stayed when I was a minor? And what are my chances on getting the B2 Visa? Can I boil milk unattended (and still keep the pan clean)? SQL Coalesce in WHERE clause I'm trying to implement optional parameters in a stored procedure that I have but I am running into a problem. Here's a simplified query to illustrate the issue:  SET ANSI_NULLS OFF  DECLARE @MiddleName VARCHAR(20); SET @MiddleName = NULL;  SELECT * FROM [Customer] WHERE [LastName] = 'Torres' AND [MiddleName] = COALESCE(@MiddleName, [MiddleName])   When I run this query I need to get one row back because one Torres has NULL in the [MiddleName] column. But the query returns zero rows. Using IFNULL() produces the same result. From researching COALESCE, I was under the impression that NULL would be returned if all expressions are NULL. As I am not a SQL expert I assume that I am missing something, but what is it.....  Thanks in advance for any help. Calculating sequential numbers into sorted table using ArcGIS Desktop? iPhone screen randomly turns on After installing iOS 10, I found that the screen on my iPhone 6s turned on at seemingly random times, and it slightly annoyed me. I now know that this feature does what it is supposed to (turn the screen on when the phone enters certain positions), but I want to disable it.  Is there a setting can I use to do so?

As I bought in excess of 5000¥, the purchase was tax free and the receipt was stapled to my passport and stamped.  Since I've now come back to Canada and no issues occurred with my imports, Is it safe to remove the receipts from my passport?  As it was stamped and stapled, there will remain a trace that something was there. Could this cause problems when I return to Japan at a later time?

As far as I know, the superconducting gap is necessairy for both zero resistance and the Meissner effect, the two hallmarks of superconductivity. So, what does it mean to have gapless superconductivity and how does it work? Thanks in advance, Greetings unsigned int vs. size_t I notice that modern C and C++ code seems to use size_t instead of int/unsigned int pretty much everywhere - from parameters for C string functions to the STL.  I am curious as to the reason for this and the benefits it brings. I have a range and need to sum it using SUM function but the result is N/A if there is any N/A value. How can I make the SUM function to treat the N/A value as 0 value?  Please help!
