Maximum length of tags Possible Duplicate:        Is there a maximum limit on the length of tags? I noticed that the tag for SQL Server Management Studio is truncated to sql-server-management-stu.  It seems like this should be an easy thing to correct, if not to allow the creation of new longer tags, but to correct existing tags that have been truncated. Any site that I visit can see my local IP (e.g. 192.168.1.102). Is there any reliable way to block this behavior? (browser setting, OS setting, router setting, etc.) I am particularity interested in Google Chrome and Mozilla Firefox, but any modern open source browser will do. If it is a browser plugin, it should be open source with a solid user base.  By reliable I mean, that I do not need to check the leakage again after every software update.  More info / what I have read so far:   There was a Chrome plugin that is not working anymore Local IP is obtained using JavaScript / WebRTC   Live Demo here:  Source code:   Firefox developers is not going to fix the leak (bug is open from 2014):  In Private / Incognito mode does not prevent this leak. If you use static IPs, and have non typical local IP (e.g. 10.66.77.88 or 192.168.212.121), then there is no need for . Your external IP + internal IP is perfect fingerprint.   Update 1: It is not duplicate of  - I want to prevent private / local IP leak, not disable all WebRTC.  Update 2: No, it is not related to header X-Forwarded-For (HTTP_X_FORWARDED_FOR), that is added when user/administrator chooses to do so. In my provided demo it is not your choice... It is Google's and Mozilla's choice to leak your private IP even when using private browsing mode.  Update 3: Ability to determine my local IP allows malicious JavaScript to quickly identify my local subnet and print on my local network printers from any website in the world without me doing anything.  This  finds my LAN printers using JavaScript.  Update 4: It is not a good idea to reveal private IP to every website. By seeing your private IP, for example 192.168.88.101, I can guess with very high probability that you are using MikroTik router. Also, I can track particular user event if user uses different browsers because local and remote IP stays the same for some time (hours or even days). Openlayers v4.0.1 support Google Maps Javascript API? I want to know if the latest version of Openlayers (v4.0.1) supports Google Maps as a Tile Layer. I can't find any document ion about this. If Openlayers doesn't support Google Maps, could someone  tell me if there is any way to do this? Pullback of a Volume Form Under a Diffeomorphism. I have an exercise here, which I have no idea how to do.     Problem: Let $ U $ and $ V $ be open sets in $ \mathbb{R}^{n} $ and $ f: U \to V $ an orientation-preserving diffeomorphism. Then show that   $$   {f^{*}}(\text{vol}_{V}) = \sqrt{\det \! \left( \left[   \left\langle {\partial_{i} f}(\bullet),{\partial_{j} f}(\bullet) \right\rangle   \right]_{i,j = 1}^{n} \right)} \cdot   \text{vol}_{U}. $$   Notation:         $ \text{vol}_{U} $ and $ \text{vol}_{V} $ denote the volume forms on $ U $ and $ V $ respectively.   $ f^{*}: {\Lambda^{n}}(T^{*} V) \to {\Lambda^{n}}(T^{*} U) $ denotes the pullback operation on differential $ n $-forms corresponding to $ f $. Explicit formulas for Stirling numbers of second kind I have seen some recursive formulas for Stirling I and II kind but I am especially interested in explicit formulas.  I was thinking and get: $$ \left\{ {m \atop n} \right\} =  \sum_{k_i&gt;0 \wedge k_1+k_2+...+k_n = m} \frac{m!}{n!}\cdot \frac{1}{k_1! \cdot k_2! \cdot ... \cdot k_n!}$$ I am not sure if it is ok but supposedly it is (I created it with combinatorics interpretation)  Can somebody look at that and tell me if it is ok/wrong?  By the way,if you have some nice formulas, I will be grateful for sharing that. Why do I not see evidence of discrete energy in the spectrum? The electromagnet spectrum looks to be continuous, yet energy is discrete. Shouldn't one see evidence of the electron's "quantum leap"? What's going on?     Moderator, please size my photo. Thank you. To show: $(\mathbb{Q},+)$ is not isomorphic to $(\mathbb{R},+)$  Now, the equation $x^{2} =3$ has a solution in $\mathbb{R}$, but not in $\mathbb{Q}$.  Hence they are not isomorphic to each other.  Is that right, or do I need to prove something else?  Thanks. 14.04 - Network manager stopped working When I started my laptop, there was no network service, and also no network icon in the top bar. It gives an error when I start OS like "Sorry, Ubuntu 14.04 experienced an internal error". When I click details, it says the error is occurred in the executable path usr/sbin/NetworkManager. Also, when I try to enter Network in the System Settings, it says "the system network services are not compatible with this version"  How can I solve this shocking issue?  p.s. I didn't install any third party packages/apps related with networking. Only system updates are installed. What is the Linux equivalent to Windows' Program Files? meaning of so much as In the following sentence, I want to know if I've understand the correct meaning or not:     This version holds that the wave function does not so much describe the state of the physical system as the state of our knowledge of the system.    Can we say that it means the wave function describes the state of our knowledge  of the system more than it describes the state of the physical system  ?  It is worth noting that in the Cambridge Dictionary, we read:  not so much sth as sth ​ If you say that something is not so much one thing as something else, you mean it is more the second thing: They're not so much lovers as friends. I don't feel angry so much as sad. While googling, I see that using  can be slow.  has a  method that is available as well.  Is there an efficient way in java to get the file size? I've just updated to macOS 10.12 and when I try to execute srm in Terminal, it says -bash: srm: command not found.   Is srm removed? How to fix this? There has been talk of how to answer a negative question without ambiguity, most often with a qualifying phrase needed for clarification. (For example, "yes, I do"/"no, I don't.)  I've noticed that other languages have a single word to address a negative question on the contrary. In German, ja means yes and nein means no. Alternatively, doch is used to respond in the positive to a negative question, in essence meaning "No, I intend to do the opposite of what your question presumes."  Take for example the question, "You don't want to go to the movie then?" German speakers could simply reply, "nein" if they don't want to go or they would say "doch" if they did want to go; an unambiguously positive response to a negatively phrased question. No need for, "no, I actually would like to go" or "yes, I'll come actually". In French, the respective equivalents of ja, nein, and doch are oui, non, and si. I imagine many other languages contain this set as well.  I am wondering whether there was at one time an equivalent word in the English language that has since (unfortunately) disappeared. Any ideas? I'm trying to go into an irb session with specific environment variables from a file with this command:  $ env $(cat env.sh) irb   But when I try press Tab after I type env. to complete it, I get this following error:  $ env $(cat env.-bash: unexpected EOF while looking for matching `)' -bash: syntax error: unexpected end of file   Another interesting thing is that if I'm logged in as root, this error does not occur.

How do I integrate Github files to Orange for ML? I am currently trying to make a facial recognition workflow with Orange but since the widgets are still prototypes they are not all available in Orange. I found the Github files for the widgets but don't know how to install this so that I can see and use the widgets in Orange. I've setup a HTTPS and FTP site in IIS but how can I add users to use the FTP site?  Does they necessarily need an account with password in the computer to be able to use it? My created page with link  The 404 page after following my new url. I read a story--the first part of one, at any rate--years ago, and haven't tracked it down since. It started with a man been sent to a planet under attack to pose as a monk--he arrived in the middle of an assault, but still had to do penance for being late. So he wore a hair shirt, that created an agonising reaction. He was captured by the attackers (who took him for the man he was posing as), who then stood off the planet in their starships and watched as a 'hell burner' weapon tumbled out of deep space and torched the planet. The attackers then explained that they weren't responsible for the hell burner, but every time they arrived at a planet, a hell burner turned up afterwards, at shorter and shorter intervals.  As the story developed, there was some kind of time travelling dimension, and a character turned out to have his organs reversed. I may have got some details wrong, but this was the shape of it.  Anyone know this story, and the author? Do effects with the duration of one minute end at the beginning or the end of your turn? The Rage class feature of the Barbarian allows you to rage for one minute given you either took damage or attacked every round. A round is defined as a 6-second interval. So the rage can last up to 10 rounds. Now my question is, does it end at the end of your 10th round or at the beginning of your 11th round? There are other effects like that, also concentration spells with the duration of 1 or 10 minutes. Sometimes those are activated before combat starts and end during combat. In general: Does an effect/concentration end at the end of your last turn during the timespan or at the beginning of your first turn after the timespan? How do I create a 50x3 cell array from a 50x3 matrix. Keep just getting a 1x1 cell array with a 50x3 submatrix?
