What's up with different contexts in android?
Diffinitive rules for using Android's getBaseContext, getApplicationContext or using an Activity's "this"
Cyclic Group Generators of Order $n$ Datepicker returning uncaught typeError: undefined 'currentDay' Share Wireless connection with Wired Ethernet Port Is there a direct proof that $\pi$ is not constructible, that is, that squaring the circle cannot be done by rule and compass?  Of course, $\pi$ is not constructible because it is transcendental and so is not a root of any polynomial with rational coefficients. But is there a simple direct proof that $\pi$ is not a root of polynomial of degree $2^n$ with rational coefficients?  The kind of proof I seek is one by induction on the height of a tower of quadratic extensions, one that ultimately relies on a proof that $\pi$ is not rational. Does any one know of a proof along these lines or any other direct proof?  I just want a direct proof that $\pi$ is not constructible without appealing to transcendence. What is the difference between HAVING and WHERE in an SQL SELECT statement? EDIT: I have marked Steven's answer as the correct one as it contained the key bit of information on the link:  When GROUP BY is not used, HAVING behaves like a WHERE clause  The situation I had seen the WHERE in did not have GROUP BY and is where my confusion started. Of course, until you know this you can't specify it in the question. How do I find out which dlls an executable will load? Make an Ubuntu bootable USB drive for a PC using Mac? What's the difference between "Service" and "/etc/init.d/"? For example, I can't install package qcad because of error: "can't find qdict.h". How can I find the package which provides the file qdict.h so I can install the package qcad? Is it possible to make armour that can survive /kill? /kill is said to be infinity damage but I have a question can you really survive it in Java edition. However, it is possible that you can pretty much survive this if you are on Minecraft Java Edition in 1.8 or lower and you can just have resistance 5 and you will survive this but can you make armour that helps you survive in 1.16 and in java-edition. In Avengers: Age of Ultron movie,      Ultron infected tech of Avengers Tower just after his birth. It means he is capable of infecting tech. Also, if this wasn't the case, he could never be able to create his drones.   Just after its birth,      He escaped using the Internet and infected digital devices across the entire planet. Again, awesome capability (think Skynet).   We also saw that      Iron Man's armor was connected to the Internet. He googled for the keyword "Hulk" during flight just before he deployed Veronica.   Then, why did Ultron let Iron Man win the fight? Why didn't he simply hack Iron Man's armor to use him as own drone? I want to talk to someone about the house that my wife and I own.  Saying, for example, "My wife's and my house is awesome," sounds a bit funny to me.  What's the best way to express this?  Clarification  I'm asking specifically about the grammar of multiple nouns in possessive form.  I'm particularly curious if it's possible to do this with a first-person pronoun (me).  I am capable of rephrasing this in other ways - my question is not how to express the idea, but about this particular grammatical construction, if it is even legal. How do you prevent web pages from appearing in the Google search index? Can I make a script always execute as root? Impact of deleting 100GB table on Mirroring I'm about to delete a large table which is approximately 100GB in size.  I'd like to understand the impact on the mirroring that's in place on this db.  Can anyone confirm? Ubuntu 14.04: very slow UI in Oracle VirtualBox Short summary: 14.04 is much slower than 12.04 even with more RAM assigned.  I'm using latest VirtualBox 4.3.10 on Mavericks 10.9.2. How can I make it faster? I know how to detect when resistors are arranged in parallel or series arrangement and I can also find their equivalent resistance in simple circuits or when resistances are connected in form of triangle but what happens when the arrangement is complex like this :   Which resistors are parallel and which are in series ? How can I find the equivalent resistance in such cases ? Is there rule or method for figuring this out ? Inverse of a diagonal matrix plus a constant I am looking for an efficient solution for inverting a matrix of the following form:  $$D+aP$$   where $D$ is a (full-rank) diagonal matrix, $a$ is a constant, and $P$ is an all-ones matrix.   gives a solution to the special case where all diagonal entries of $D$ are the same.  The  formula is also capable of providing a solution to this problem by setting appropriate $u$ and $v$, but it loses efficiency ($O(n^3)$ time complexity to compute) at high dimension. I am hoping to get a result in the same form so the space and time complexity are both $O(n)$. How can mixed content compromise an entire HTTPS session? Google Chrome is probably one of the stricter browsers out there in terms of highlighting SSL errors.  Most browsers will point out when you are viewing an HTTPS page which loads insecure images/Javascript, I understand how this is a security issue - an attacker could have modified the non-SSL content in a way which gives them access to the secure content, injected some javascript for example.  However once you have viewed an HTTPS page with mixed content, Google Chrome will continue showing you the mixed content warning (a red line through the 'https://') for as long as you stay browsing the same domain, even for subsequent pages which only include other HTTPS resources. Only once you navigate to another domain, or open a fresh tab does it tell you you're secure again.  What is the danger it's protecting you from here? How could mixed content on a previous page actually affect the security of subsequent secured pages? I understand that mixed content should be flagged up, but there must be a specific reason that Google is persisting this warning, other than "Well you still need to know about it" The user who first created a tag wiki is treated as owner for suggested edits
