Use of "post-hoc" tests - do these require an ANOVA to be performed first?
Do we need a global test before post hoc tests?

Access pictures from Pictures app in my android app Just like the iPhone has a UIImagePickerController to let the user access pictures stored on the device, do we have a similar control in the Android SDK?  Thanks. Why does the Contains() operator degrade Entity Framework' Linq queries? Converting MultiLinestring to Linestring with PostGIS How to delete a file ending in a dot in Windows 7? After installing Cygwin on Windows 7 and realizing I'm better of with using Linux on a different partition, I wanted to uninstall it. However, Cygwin has no uninstaller so I was left with the option of deleting the whole folder it was installed in – which I did.  The problem is that a single file remained, in the whole directory tree, named README. at  C:\cygwin\usr\share\texmf-dist\doc\latex\hausarbeit-jura\README.  I know Windows isn't supposed to allow files with names ending in ., but this one obviously got through, and I cannot delete it. When trying to do that, I get     Item Not Found      This is no longer located in C:\cygwin\usr\share\texmf-dist\doc\latex\hausarbeit-jura. Verify the item's location and try again.   When viewing the properties of the file (Right-click, Properties), Windows tells me that it has 0 bytes.   However, when viewing it in the explorer window, and clicking on it, the windows status bar thing tells me it has 517 bytes.  Any ideas on how to get rid of it? Why do I get blurry pictures when I take a lens attachment off? Search favorite questions by tag Favorite questions on Stack Overflow I feel is highly unused feature of all the features provided on the site. (This again is my personal opinion)  I have favorited around 90 question till date and it gets very very very difficult if I want to search for a question which I remember I have favorited, which defeats the entire purpose of one favouriting a question, so here is my small suggestion.

So I have a torus, and I need it to "telescope" open -- kind of like Pacman's death animation, but with a torus instead of a sphere.  I'm very new to 3D modeling/animating so I really have no clue how to tackle this problem.  Any advice to help me get pointed in the right direction would be most appreciated :) There was the following paragraph in the article that came under the title, “GOP and the rise of Anti-knowledge” written by  (October 29, 2015):     “English unfortunately doesn’t have a precise word for the German   “Fachidiot,” a narrowly specialized person accomplished in his own   field but a blithering idiot outside it. In any case, a surgeon is   basically a skilled auto mechanic who is not bothered by the sight of   blood and palpitating organs. We need the surgeon’s skills on pain of   agonizing death, and reward him commensurately but that does not make   him a Voltaire.”    In Japanese we have a word, 専門バカ, of which literal translation is “specialist idiot” meaning exactly same as defined the above - a narrowly specialized person accomplished in his own field but a blithering idiot outside it.  I’m really curious about the absence of short descriptions of the specialist who knows nothing more than his specialty area in English like German “Fachidiot,” and Japanese "専門バカ."  Isn’t there really any short word counterpart to “Fachidiot,” specialist’s ignorance, for instance, in English?  P.S.  I found "narrow-minded specialisit" as a German-to-English translation of "fachidiot" in the web site, Interglot translation dictionary.

Add JS to NewForm.aspx of a list Sandbox modifies subject on email sent from trigger I am writing a trigger in a sandbox, and am sending an email through the sandbox.

Long live universal login Pgfplots: how to fill bounded area under a curve using addplot and fill? As far as I see the "Blatantly off-topic" flag      Blatantly off-topic (this question has nothing to do with %site topic%)    is only available for low-rep users without the close vote privilege.  What is the reason to remove this option for high-rep users? I think it could be very usefull in some cases where now we must select      Other (add a comment explaining what is wrong)    option and waste time to type obvious message for a reason. I am trying to prove the existence of the square root of $2$.  I have some steps with a very vague explanation and I would like to clarify.  The proof: Let  $$S=\{x\in\mathbb R\mid x\geqslant 0 \text{ and } x^2&lt;2\}.$$  I understand the proof of LUB, ∝   and so I am at the step where $\alpha^2=2$.  I know that we are to prove by contradiction so we state let $\alpha^2 &lt;2$ and $\alpha^2 &gt;2$.  Now my instructor wants us to use the Archimedean Axiom $1/n = \varepsilon$.    $(\alpha^2 + 1/n)^2$  then what..... How was this answer posted after this question was closed? Question:   Answer:   The question was closed at 11:57:57 (according to the hover-over-"x-mins-ago" bar) and the answer was posted at 12:16:35. It's a fairly lengthy answer, so it's possible that it was started to be written before it was closed but I swear I've started to answer a question then I got a banner along the top saying "this question has been closed" and the answer was no longer post-able. Is ignoring emails acceptable in academia? As a grad student, I just find it tremendously frustrating when emails are ignored by faculty (both at my institution and at other places). Is this acceptable? I'd be content with a simple response with one line along the lines of "I have read this email and am busy right now, will respond in X days when I can write a more detailed email." I understand that, as a first year student in my field, I'm not really in a position to request anything of anyone, but it just seems like common decency.  Instead, I never hear back, as if my email has been jettisoned off into oblivion.
