How to use CardLayout with Netbeans GUI Builder
How do I work with the Card Layout in the NetBeans GUI builder?
Why does the find command blow up in /run/? I used the following command to check python versions as given by . It does work except for one error, shown below. Can any one explain why?  $ sudo find / -type f -executable -iname 'python*' -exec file -i '{}' \; \     | awk -F: '/x-executable; charset=binary/ {print $1}' \     | xargs readlink -f | sort -u | xargs -I % sh -c 'echo -n "%: "; % -V'   Error:  find: ‘/run/user/1000/gvfs’: Permission denied How do I get object names to appear in the render? In my scene I have multiple objects (30+). In the viewport I have the handy control of selecting (in the Properties Editor) Object> Display> Name and copying to selected.  This is beautiful for diagrams etc. as wherever my view is at whatever distance these labels have been placed instantly, always face me and are always the same size.  How can you get these to display in a rendered view?  Is the ONLY option to manually create a label for each object, get them to track to your camera (Probably have to track to an empty miles behind your camera rotation otherwise they offset if your camera isn't facing exactly front on to an object) and add some sort of scaling property to change depending on how far away you are? Hoping someone can give me some thoughts on what might be going on here so I can be a bit more informed when I call a plumber.  Situation is, we got our water heater replaced a few years back and ever since this has been an issue. It's more noticeable when it's cold outside it seems, but still seems to be a year round problem. Whenever we  use hot water, we basically run out of it within minutes. In order to get an acceptable amount of hot water (enough to take a 10 minute shower), we literally have to prime the water first. By that I mean I have to turn on the hot water, let it run for a couple of minutes, then turn it off and wait 20 minutes. Then when we go to use the hot water again we'll get hot water for a respectable amount of time. Now I am fairly ignorant to all this, but it seems a 71 gallon hot water heater should be capable of holding enough water to not need to be primed like this. I should be able to take a 30 minute shower, let alone 10 without running out. My shower this morning was decently warm for maybe 2 minutes before it was just warm-ish.   So if anyone can give me some ideas on what might be going on I would appreciate it. We've just put up with this for some years assuming perhaps it was some eco friendly thing. Like the system doesn't maintain much hot water in the tank so it's not always running and only heats water up when you start to use it? I hope that isn't the case though and even so, I should be able to get more hot water out of it. Any help?  UPDATE Sorry everyone, I meant to tell you all that the water heater was gas. The pilot light is lit. I don't recall the specific model though I can look that up if people think it will help. I have actually turned up the thermostat on it above the default and when the water heater is putting out hot water, it can be very hot. Too hot. But again, that requires us to prime it before we get any decent amount of hot water out.  UPDATE 2 Looked it up, I believe this is the model info if that helps anyone: State Select: High Output.

I tried using MySQL Administrator, but I got the following error:     The selected file was generated by   mysqldump and cannot be restored by   this application.   How do I get this working? I am trying to solve a 2 part question, the first part is to expand $\sqrt{1-x}$ up to and including the term $x^2$ which I did.  This gives me $1-(0.5)x-(0.125)x^2 + ...$  However, the 2nd part of the question says that by taking $x=(1/64)$ in the expansion of part (i) -> which refers to the one above, deduce that $\sqrt 7 = 10837/4096$. How do i do this part?  EDIT (After Hint Given By SimpliFire):  $$ \sqrt{1-\frac1{64}}=\frac{\sqrt{63}}8=\frac38\sqrt7 $$ $$ =\frac83\sqrt{1-\frac1{64}}\;=\sqrt7 $$ $$ =\frac83\left(1-\frac12\left(\frac1{64}\right)-\frac18\left(\frac1{64}\right)^2\right)\; $$ $$ =\frac83\left(1-\frac1{128}-\frac1{32768}\right)\; $$ $$ =\frac83\left(\frac{32768}{32768}-\frac{256}{32768}-\frac1{32768}\right)\; $$ $$ =\frac83\left(\frac{32511}{32768}\right)\; $$ $$ =\frac{260088}{98304} $$ $$ \frac{10837}{4096}\;\approx\sqrt7 $$  I'm not sure if I can present it like this, if it is okay i will post it as my answer :X What should I do when my neural network doesn't generalize well? If $p$ is congruent to $2 \pmod 3$, how can I prove that all $a$, $1 \le a \le p-1$ are cubic residues $\mod p$? If $p$ is congruent to $2 \pmod 3$, how can I prove that all $a$, $1 \le a \le p-1$ are cubic residues $\mod p$?  Here's what I've done:  $1^3$ congruent to $1 \pmod p$ thus, 1 is a cubic residue, Also $(p-1)^3=(p-1) \pmod p$ implies  $$(p-1)^3 - (p-1) = (p-1)[(p-1)^2 -1] = (p-1)(p^2 -2p) = p(p-1)(p-2) $$ implies $$p|(p-1)^3 -(p-1)$$ Thus  $p-1$ is a cubic residue $\mod p$. Now I don't know how to show for $1\lt a \lt p-1$ are all cubic residues when $p$ is congruent to $2\pmod 3$. Punctuation in an indirect quotation Consider the brief passage:     "I love your work, but calling you 'the artist' {1} just doesn't seem to be   cutting it anymore. What shall I call you?"      "OK. Call me George." {2}   So my instincts tell me to put {1} in single quotes as opposed to no punctuation (or perhaps even italics) but to do the opposite for {2}. Is this right? Why?  Let me expand this one further iteration:     "Wow, that's a great name, especially with this crowd. Maybe for your next book    you should call yourself Ringo."{3} jquery disable form submit on enter I installed Linux Mint in 2 partitions: / and /home  Windows 8 is under UEFI boot mode.

Thanks a lot! I am running Ubuntu 14.04 from Windows, using virtualbox 5.0. I tried several options to make size of Ubuntu in virtual box larger, but none helped so far.   I am using latest virtual box with latest guest add on installed. sudo apt-get install virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11 I went to Ubuntu 'software and Updates' and made sure that under 'Additional Drivers' tab, 'using x86 visualization solution...' is active. In virtualbox window, under view->virtual screen 1, all 'resize to' options are disabled.   None of these options helped. This is frustrating. Any comments or help? Can the problem be I am using 64 bit system? Does this problem occurs in earlier/later versions? If not, please suggest a 'good' version of Ubuntu for virtualbox.
