I am getting a java.io.FileNotFoundException when trying to update PyCharm/IntelliJ:   Ubuntu 16.04. Installed PyCharm as per GetDeb in . It says it wants to update from PyCharm 2016.3.2 to 2016.3.3.  It says I do not have write access to /usr/share/pycharm.  So I run sudo pycharm. After Downloading Patch File and "Some conflicts were found in the installation area" where its "Solution" is "IGNORE" I click Proceed.   Get "Failed to Apply Patch":  Temp. directory: /root/.PyCharmCE2016.3/system/tmp/patch-update  java.io.FileNotFoundException: /root/.PyCharmCE2016.3/system/log/idea.updater.files.tmp.0/temp.tmp.1/bin/pycharm.png (No such file or directory) at java.io.FileInputStream.open0(Native Method) at java.io.FileInputStream.open(FileInputStream.java:195) at java.io.FileInputStream.&lt;init&gt;(FileInputStream.java:138) at com.intellij.updater.Utils.newFileInputStream(Utils.java:260) at com.intellij.updater.UpdateAction.doApply(UpdateAction.java:65) at com.intellij.updater.PatchAction.apply(PatchAction.java:201) at com.intellij.updater.Patch.lambda$apply$2(Patch.java:323) at com.intellij.updater.Patch.forEach(Patch.java:372) at com.intellij.updater.Patch.apply(Patch.java:321) at com.intellij.updater.PatchFileCreator.apply(PatchFileCreator.java:84) at com.intellij.updater.PatchFileCreator.apply(PatchFileCreator.java:76) at com.intellij.updater.Runner.doInstall(Runner.java:303) at com.intellij.updater.Runner.lambda$install$0(Runner.java:272) at com.intellij.updater.SwingUpdaterUI.lambda$doPerform$4(SwingUpdaterUI.java:190) at java.lang.Thread.run(Thread.java:745)   I think IntelliJ is involved because that is a default for the editor settings.
I want to install the PyCharm IDE by JetBrains for Python (free community edition).  I managed to , but I do not know how to install it. Can you please help me?
How to stop reordering of the same kind multiple preview windows in task switching? Getting Error while starting Google Map v2 Install 18.04 server without network connection Is "Don't do it" a valid answer? If someone asks how to do XYZ, and you think doing XYZ at all is a Bad Idea™, is it valid to post an answer saying so? You aren't answering the question, but instead, arguing the question's validity.  You could do this in a comment, but I don't think comments carry enough weight on occasion.  For example, I came across this today ; for those not wanting to link away:     I would like to build a wiki based website about professors, so that students can share information and check the reputation of the professor before working for him.   and I really wanted to post an answer that said, "I think this is a very bad idea". (In fact I did anyway, despite awareness that it could get myself flamed.)  Was I wrong? What should I have done instead? Is there any tool available for extracting the X, Y and Z coordinates from a .las file and exporting them to a .csv or similar file? Multiple regression in R results different to simple linear regression? Can I access private members from outside the class without using friends? Disclaimer Yes, I am fully aware that what I am asking about is totally stupid and that anyone who would wish to try such a thing in production code should be fired and/or shot.  I'm mainly looking to see if can be done. Now that that's out of the way, is there any way to access private class members in C++ from outside the class?  For example, is there any way to do this with pointer offsets? (Naive and otherwise non-production-ready techniques welcome) Update As noted in the comments, I asked this question because I wanted to write a blog post on over-encapsulation (and how it affects TDD).  I wanted to see if there was a way to say &quot;using private variables isn't a 100% reliable way to enforce encapsulation, even in C++.&quot;  At the end, I decided to focus more on how to solve the problem rather than why it's a problem, so I didn't feature some of the stuff brought up here as prominently as I had planned, but I still left a link. At any rate, if anyone's interested in how it came out, here it is:   (I suggest reading it before you decide that I'm crazy). Opening a context menu (with the Menu key) Why are there holes in the icing? What is the maximum convergent $x$ in the power tower $x^{x^{x^{x\cdots}}}$? In the power tower $x^{x^{x^{x\cdots}}}$ where there is an infinite stack of $x$'s, what is the maximum convergent number? I know the answer by playing with the form $x^y=y$ and using Mathematica, but I don't know how to solve this by hand. The value of a, b and c for this integral Find out the value of $a, b$ and $c$, for which $$ \lim _{x\to 0}\:\:\frac{1}{x^5}\left(\int _0^x\:\left(a+b \cos\left(t\right)+c \cos\left(2t\right)\right)dt\right)=\frac{1}{5} $$  My first thought was to separate the integral into multiple ones because i thought that it is pretty clear that each integral is a common one and a,b,c are constants and can be taken out . After I solved the integral, that's where I had the problem. I couldn't do the limit of the result that I've got in order to find out the value of $a,b$ and $c$ . Determining the characteristic of a field Show every nonempty compact Hausdorff space is not the countable union of nowhere dense sets I know this proof is somewhat similar, or related to the Baire's Category Theorem but I can't seem to figure out how to do it.  The Baire Category theorem asserts that if X is a complete metric space or a locally compact Hausdorff space (my case), then the complement of a countable union of nowhere dense sets is always nonempty.  How can I use this on the proof? Present Perfect with the word "ago"? First, I check that my native language is not English, and the problem described below met on one of the exams.   With this sentence:      "The most important news is that my parents [...] a new restaurant a few   weeks ago."   Is the correct tense to use the Present Perfect (have opened) or Past Simple (opened)?   I know that the word "ago" but rather that time Past Simple, but is it also possible to use the present perfect in some cases?  I would be grateful for clarification. touchdown held down libgdx Motivation  I want to include a list of related equations, say, for a proof, in my LaTeX document. As far as I know, I have two good options, eqnarray and align.   Question  What is the difference between eqnarray and align, and how do I know which I should be using? Or does it matter at all? Screen goes white when posting a comment I'm self-studying Guillemin and Pollack, but I'm stuck on Problem 3 of section 2. It says that if $V$ is a vector subspace of $\mathbb{R}^N$, then $T_x(V)=V$ if $x\in V$.  If $x\in V$, then since $V$ is a manifold, there is a local parametrization $\phi: U\to V$ where $U$ is open in $\mathbb{R}^k$. Without loss of generality, we can require $\phi(0)=x$. Then $T_x(V)$ is defined to be the image of $d\phi_0$ on $\mathbb{R}^k$.   An arbitrary element of $T_x(V)$ looks like $$ d\phi_0(v)=\lim_{t\to 0}\frac{\phi(0+tv)-\phi(0)}{t}=\lim_{t\to 0}\frac{\phi(tv)-x}{t} $$  but this doesn't seem very useful to show $T_x(V)=V$. What is the right approach? Can you recommend a Java library for reading (and possibly writing) CSV files? I have video tutorials that I want to show in my presentation with beamer class. I don't want the video files get embedded to the PDF because they will make the PDF size very very huge.  If you know how the videos can be played on the HTML with a reference rather than embedding the video file to the HTML file, I want something like this to be applied to my PDF presentation. I just want to reference the video URL from my PDF presentation.   Shortly speaking, can we use media9 to show a video on a PDF but the video is not embedded to the PDF?  Uploading those videos to a web server might be difficult for me because internet connection is very slow and sometimes not available in the presentation room. :-)
