How can I have Safari on OS X remember to permanently trust a website with my current location? The only options on the location privacy prompt are 'Allow' or 'Don't Allow', with a 'Remember my decision for one day' modifier checkbox as well. But what if there's a site that I trust in perpetuity? I want to give it permission to access my location forever. Why can't I do that?  Safari 8.0 on Mac OS X 10.10 Yosemite
How do I permanently allow a website to access my location? In iOS, I only need to be asked once whether I want to allow a website to share my location data. Is it possible to permanently do this in OS X version of Safari as well?
I'm having some trouble understanding cosets.  If I understand it correctly, cosets form a partition. So, if I have $|G:H| = 2$, then $G = H \cup xH$. Right?  In an exercise, I'm asked the following:  "For $G$ group and $H \le G$ such that $|G:H| = 2$, prove that $x^2 \in H$ for any $x \in G$"  If $x \in H$, then $x^2 \in H$ because $H$ is a group. But, if $x \notin H$, then $x \in gH$ for any $g \in G$, right? Then $x^2$ = $(gh)^2$ but I can't see why this is in $H$.  Can you give me some hint? Thanks for stopping by. Root filling up although it should have some space This has been perplexing me for some time. I'm on Ubuntu 11.04. My root partition is filling up and I can't figure out what's causing it. Even stranger, when I run df -h, this is the output:  Filesystem            Size  Used Avail Use% Mounted on /dev/sda2             9.2G  8.8G     0 100% /   As you see, there should be about 400 MB free, but Avail shows 0. What could be causing this? I've even uninstalled some programs to free the space and it fills up again. Suggestions on how to find out which, if any, files are filling up the space are also welcome. Help needed with definite integral for $\lim_{n\rightarrow \infty}\sum_{k=1}^{n} \frac{1}{n+k}$ How to handle :java.util.concurrent.TimeoutException: android.os.BinderProxy.finalize() timed out after 10 seconds errors? Cleaning small block of code (Switch, Case, If?) How to clear the interpreter console? I would like to show that $a^n \mid b^n$ implies $a \mid b$  I thought I could convert it to congruences and work backwards, but as far as I remember, $a \equiv b \pmod{m}$ implies $a^n \equiv b^n \pmod{m}$, not the opposite, unless $m$ is prime. Is that right?  So I am not sure how to approach this one. Any ideas?  Thanks!

In my blog I publish articles with date below under it.  My questions are:   Using dates will have positive impact or negative impact? After few years of publishing the post, since my post age is old will it remain in same position of search results or it will go down? Finally, should I use published dates or not? How to find the id of the last added feature using pyQGIS? Is it possible to programmatically (in python) access the attribute info of the last added feature in QGIS 2.0 before edits are saved? I'm failing to find a way to get the ID and subsequently other attributes of my feature of interest (the one most recently added).  idx = layer.fieldNameIndex('myField') myList = [] lastEdited = ID THAT I'D LIKE TO RETRIEVE for feature in layer.getFeatures():     if feature.id() == lastEdited:         print feature.attributes()[idx]   From this I'd like to get 'myField' of my most recent addition.   UPDATE: Following lead of this , I was able to achieve my goals via the Python console, but am failing to get it to work for my plugin.  def updateTableWidget(self, fid):     idx = layer.fieldNameIndex('myField')     myList = []     for feature in layer.getFeatures():         if feature.id() == fid:             myList.append(feature.attributes()[idx])   Via the python console, I was able to connect to my layer like so:  layer.featureAdded.connect(updateTableWidget)   After adding a QgsMessageLog to my function, the attributes were correctly identified. I now have a beginner python issue, however. Calling the function in my plugin as shown below gives me TypeError: updateTableWidget() takes exactly 2 arguments (1 given):  self.updateTableWidget()   The function was called from feature form python file. Schengen Visa Refusal: Justification for the purpose and conditions of the intended stay was not reliable How to join a LAN / IPX game on Diablo 1? Recently some of my friends and I grew nostalgic about the original Diablo and realized we've never truly tried the multiplayer aspect of that game. So we set up a modern VPN LAN solution via tuungle (using the appropriate IPX Wrappers) but the problem is, while any of us can manage to create session in Diablo FULL, others cannot find a way to join my IPX/LAN game.  There are no "join" buttons in the game itself.  I've read somewhere that Spawn version is a trial version but can be used to join Multiplayer games. If they can, is it possible for them to play the entire game on LAN or is trial restricted from choosing some classes/accessing some areas?  Or are there some other ways to join? How do you mark a struct template as friend? For simple linear regression, the regression coefficient is calculable directly from the variance-covariance matrix $C$, by  $$ C_{d, e}\over C_{e,e} $$ where $d$ is the dependent variable's index, and $e$ is the explanatory variable's index.  If one only has the covariance matrix, is it possible to calculate the coefficients for a model with multiple explanatory variables?   ETA: For two explanatory variables, it appears that $$\beta_1 = \frac{Cov(y,x_1)var(x_2) - Cov(y,x_2)Cov(x_1,x_2)}{var(x_1)var(x_2) - Cov(x_1,x_2)^2} $$ and analogously for $\beta_2$. I'm not immediately seeing how to extend this to three or more variables. A novel where a woman from "future" of 1999 speaks leet-speak I'm trying to remember the name of a novel/series I read back in the mid-eighties.  I can't remember the author other than that it was a known older author.  I initially thought maybe Saberhagen or Harrison, but can't find it in their bibliographies.  It involved a collection of 4-5 people from different times/places.  The distinctive bit I can remember was that one of them (not the main character) was a cyberpunkish woman from the "future" of 1999 who spoke in futuristic dialect of English that the other characters, including the protagonist, from the "present" (from the eighties) could not understand.  Unfortunately, I don't remember much else of the plot other than that they were making their way through ruins. We know that $$\int_0^\infty \left(\frac{\sin x}{x}\right)^2 dx=\int_0^\infty \frac{\sin x}{x} \, dx=\frac{\pi}{2}.$$ How do I show that $$\int_0^\infty \left\vert\frac{\sin x}{x} \right\vert \, dx$$ converges? ggmap: create circle symbol where radius represents distance (miles or km) How can I know what speed card to get for my camera? Cameras rarely specify exactly what speed cards you should be using in them - I just checked the manual for my DSLR, and all it says is to use an SDHD card, and a "high speed" card should be used for recording video.  On the other hand, there are a number of different rating systems for memory card speed (33x! 150x! Class 2! Class 10!) and price seems to increase with speed.  Is there any way to test the maximum write speed the camera is capable of?  Are the read/write speeds documented anywhere? Windows Smart Screen can't be reached in Windows 10?
