How to have PRTG Server running beside Apache?
Why not use a WAMP stack?
Not packages and not all applications. Just the applications user installed by himself from whatever source (Software Center, manually added PPA, etc.). If the above is not possible - a list of all installed applications or at least a GUI which lists the applications so I can take screenshots of it.  I've read a dozen of similar questions and people posting answers usually don't even get close to OP question merit. Please note that my question includes 'user installed'.   Answer: It is not currently possible in Ubuntu Linux.  (choosing tijybba's answer as the closest one though) Firefox: Downloading files with drag and drop Storage for Eldritch Horror Is there an optimal strategy for storing Eldritch Horror cards and tokens so that game play is facilitated.   I am not looking for answers that including "zip bags" and other things to keep the game element safer while is storage. Although, a strategy that works well for both cases will clearly be superior to one that only works for game play.  I am not limiting this to commercial solutions. I am quiet happy to build your custom made solution if you release the specification/plans of course!  Although, it it requires a 3D printer, more power to you. Tagging best practices I am wondering what I should do when tagging a question that fits multiple tags, in the particular case were the question might belong to general as well as more specific tags.  Let me give you an example to illustrate this:  Let's say I have a question about ASP.NET MVC 3.0 and I use C# as my main language.  The following tags could apply:   c# .net .net-4.0 asp.net asp.net-4.0 asp.net-mvc asp.net-mvc-3   Tagging with C# might make .NET redundant (I don't think C# is used anywhere else outside of the .NET scope), and tagging with  certainly makes  and  redundant. However, my question would get a better visibility with tags such as ,  and , as probably no one browses a tag as specific as .  How shall I tag my questions? Using more general or more specific tags, or a mix of the two? Can a hyphen be used without anything on the right side? Proving by induction that $\sum\limits_{k=2}^n \frac1{k^2}\le 1$ How can I efficiently drive an LED? I understand that I can not connect an LED directly to a battery because it will draw too much current. Thus, there must be something else in the circuit to limit the current. What options are there? Are some methods more efficient than others? SSD drives lifetime Some years ago when I was looking to buy an SSD drive, I remember reading about how SSD drives had low lifetime with frequent read/writes, so I backed off.  Now I see this in Specifications:  MTTF: 1,000,000 Hrs    That's 114 years (ok, it could be a few years less, but still WOW)    What has changed since then? What is your personal experience about this technology? What does "I have straight A's." mean? I have a cryptography workshop question I'm having trouble with as follows;  Person A creates a cipher $E_k(m)$ which produces a ciphertext from message $m$ using key $k$. The function inside $E$ is kept secret but the length of $E_k(m)$ is known.  Person B recommends "increasing" security of the cipher by instead doing :   $(E_k(m) \oplus m)\ ||\ (E_k(m) \oplus 1111...11)$      Does this in fact increase security of the cipher or increase new problems.  My thinking is, depending on the function within $E$, xoring the output of the cipher with the plaintext message $m$ could expose the key $k$, meaning the extra complexity is for nothing. Am I on the right track, or am I missing something?  I have tried searching for examples of similar schemes and found nothing (which probably means it's not a good scheme) but I need to justify my answer.   Any steers in the right direction would be greatly appreciated, I'm more than happy to do the research myself just unsure what specifically to look for.   Unfortunately the above context is all I have been provided for this question. How can I use JavaScript on the client side to detect if the page was encrypted? Is it possible to detect, on the client side, whether the user is using an encrypted page or not?  Put another way -- I want to know if the URL of the current page starts with http or https. Today, on C.SE, I reviewed some 'Late Answers' and First Posts.  I was not even near my daily vote limit.  And yet, I was given a message that said      comments disabled on deleted / locked posts / reviews   It seems I was not the only one either:   The workaround, of course, was simply to go back and provide the guidance - but was this a design or a bug?  If it is design, why would you want to discourage the feedback? Especially with first posts, there is often a high percentage of 'didn't read the FAQ' usage, which can best be addressed by gently providing guidance. (e.g. "Unfortunately, this doesn't answer the question" or "This reads like a comment" or "This really isn't on-topic here - can I suggest you checkout our [faq]" etc...)  Timely first post guidance goes a long way towards making good users.   If it was a bug, was other functionality silently rolled out? Weird sharp vertices with subdivision modifier I have a simple skull model, to which I applied the subdivision modifier. For the most part everything works as expected, except I keep getting these weird sharp vertices and I can't seem to figure out how to flatten them.    I'm using Blender 2.8. Is this some kind of feature I can disable/enable for particular vertices? The distance between the sharp vertices and the gray outline differ.    Any suggestions please? Thank you!  EDIT: I also tried selecting as both - vertexes and edges and then applied Edge->Clear Sharp, but nothing changed. I use Kali Linux and discovered the following "problem":  root@kali:/proc/self# ls -l cmdline -r--r--r-- l root root 0 May 27 13:43 cmdline root@kali:/proc/self# chmod 744 cmdline chmod: changing permissions of `cmdline': Operation not permitted   I am not allowed to change the permissions of that file... but I am root? Why is that? Are there ways to work around this? I allready tried some things like moving the file (what is obviously not possible), change the runlevel etc. I want to compile my program with the latest version of gcc.  Ubuntu 14.04 comes with gcc 4.8.2, however there's 4.9.0 available, moreover, I see that it is available as a package: . I tried to install it  sudo apt-get install gcc-4.9   but it says  Reading package lists... Done Building dependency tree        Reading state information... Done Note, selecting 'gcc-4.9-base' for regex 'gcc-4.9' gcc-4.9-base is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.   Looks like it is already installed, just not as the default one? How do I utilize it to build my program? How to interpret the significant interaction of two non-significant main predictors? I have two non-significant main binary variables in my binary logistic regression model, but their interaction is significant. The variables are centered and no multicollinearity is the case (all VIFs about 1.0). The main variables are nonsignificant, but their interaction is. I want to interpret that significant interaction of two non-significant estimates.   It would read something like this: the effect of the variable A is less visible in the level 1 of the variable B (B1) and more visible in the second level of B (B2). Or I can say the same thing about the effect of B being less visible in A1 and more visible in A2...  However, the problem is that neither the effect of A, nor the effect of B are significant! So the above interpretation, although seemingly correct, sounds inconsistent or strange. (How a non-significant effect is supposed to be boosted by the other variable?)...   On a second thought, it seems that it is actually possible. For example, if I exclude cases with B2 from my sample, now the effect of A in the sample would show up as significant (it is B2 cases in the sample that disallow A to appear as significant)... This is getting more clear in my head now, but do you still have something other than the above interpretation in mind? What is the difference between local and global sequence alignments? There are a bunch of , and I don't want to get bogged down in the maths behind them as this not only between software but varies from software version to version.  There are two main divides in the programs; some use local alignments and others use global alignments. My question is threefold:   What are the fundamental differences between the two? What are the advantages and disadvantages of each? When should one use either a global or local sequence alignment? Why images are blury when extracting image sequence from video clip? I have an issue when generating an image sequence from a video clip. Pictures 1,2,and 3 are three consecutive images from a video clip. Picture 4 is a close-up of the heel of one of them. The camera is on a tripod. As you can see there is no issue with the brick wall, but with any moving part there is. The camera is a Panasonic HDC-SD100. The clip is AVCHD 1920/1080. If I use VLC to extract the image sequence there is no issue. I use all the default settings except for the rendering resolution which I set to 100% and image compression to 0%. I have the issue with Blender 2.79b and 2.80. With this image issue it is impossible to do camera tracking. Any ideas what I need to do in order to solve this. Best regards. In De Broglie's Explanation for Bohr's Quantization Condition, why do we not use 2πr = n λ/2, why do we use 2πr = n λ? In de Broglie's explanation for Bohr's quantization condition, why do we not use $2\pi r = n\lambda/2$, why do we use $2\pi r = n\lambda$?  We know that in waves on strings, for standing waves creation in a string between two rigid supports, we use "Length of String" $ = n \lambda/2$. Why do we not use a similar concept here? There is some conflict or error I don't understand. I can skip it and nothing visible happens. The output is okay and everything seems to be fine. Still I would like to get rid of the error message.
