I'm using wordpress multiste 3.3.1 I'm not gonna update it in the future. So I disabled all upgrade functions.  I want to remove the wordpress admin bar from both frontend as well as dashboard.  I can remove it from frontend using this code.  add_action( 'init', 'disable_admin_bar', 1 ); function disable_admin_bar() {     add_filter( 'show_admin_bar', '__return_false' ); }   But i couldn't find any solution to remove it from dashboard.   I don't want to use css solution to hide admin bar and I'm ready to edit the core files to remove it  Can anyone help me to remove it completely?. Thanks
count() returns a different amount than a simple select I tried for a while to classifiy the singularities of $\frac{1}{z}-\frac{1}{\sin z}$ at the origin, but I am stucked. Is there someone who is able to help me at this point? Why is this markdown for a link not showing properly? The Stack Exchange (Personal Productivity) markdown  is showing literally rather than as a named link. Don't know why. show that $x$ is in $\ell^1$ if $\sum x_ny_n$ is convergent for all $y=(y_n)\in{c_0}$ If $x=(x_n)$ is a sequence of complex numbers such that the series $\sum  x_ny_n$ is convergent for all $y=(y_n)\in{c_0}$. Then prove that $x\in{\ell^1}$. Can anyone tell me what is the meaning of $c_0$  in this question and how to proceed on proving it. One of my friends said that I would die if I drank distilled water (we were using it in a chemistry experiment) I gave it a go and surprisingly did not die.  I did a bit of  and found    It said that drinking only this kind of water could definitely cause death, as distilled water was highly hypotonic and it would make the blood cells expand and finally explode and ultimately cause death.  I wanted to know exactly how much of this water on an average was needed to be consumed to cause death. Mail App keeps popping up in the background in Mac OS Mojave I've noticed in the last couple of days that there have been a few occasions when there's been a sudden surge of questions in the SO "Reopen" review queue.  Normally there's either no questions at all to reopen or at most three or four, and that's still the case, except that for the last couple of days I've gone to the review page and seen about fifty-odd questions in the queue, where just moments before there had been none.  I've gone through the reviews and the questions themselves seem reasonably legitimate (including the occasional audit), so I'm not questioning that... it just seems odd that there would be so many more than usual all of a sudden, and that they'd all appear at once.  Anyone got any insights, or should I just chalk this down as "one of those things"? Hero rescues a minor deity, granted a wish of small value; gets a girl As a high school student just starting in science fiction, I read a short story collection in paperback that included this story – not quite a short-short, but not very long either.  I think that it was written by a familiar author, since the collection was one of those “Best Of…” anthologies.    Our hero is a sympathetic young guy trying to get ahead, in love with a beautiful neighbor, but hopeless in love.  He rescues a miniature Minor Deity (and I've forgotten the mechanism – rescued from a cat perhaps?) and gets a wish in return.  The catch is that since this is only a minor deity, the value of the wish is small – and I forget the actual value, perhaps $2.49.  He asks for help winning at the races to help get the girl – and the minor deity says sure, but the payoff can only be $2.49.  How about help rescuing her from a calamity like an earthquake?  Sure, but the total damage can only be $2.49. Other alternatives are discussed, but the value can only be $2.49. Frustrated, our hero thinks about the problem, but the Minor Deity thinks he has a solution.    Later that evening, the girl knocks on the door, he opens it to her welcoming arms, and the night passes.  The next morning, our hero finds a small clipping on the floor, an article stating the latest estimates of the total value of the elements in the human body were… $2.49.  (The whole story was building to that punch line.) We know that the needle that is used in a compass is a permanently magnetized ferromagnetic material and commonly steel is used.  If we used an unmagnetized iron needle instead, would it still align with Earth's magnetic field lines? If yes, how?

Schengen Visa Refusal: Justification for the purpose and conditions of the intended stay was not reliable I notice that in a pdf file compiled from Latex, "fi" such as in "field" cannot be separated as "f" and "i" when copying text out of the pdf file.

When I open a new Window in Chrome on Windows 7 (by pressing CTRL+N), the new window does not exactly overlap the existing window.   Instead it is offset to the right slightly.   So, immediately after opening a new window I have to manually move it to the left so that it uses the full screen real estate.   Is there a way to prevent this offset?
