Is there any way to make the Ubuntu Dash a 'start-up application'?

Drupal is fast at develop, but the performance is so poor.  It is hard to reach 50 request per second.  And there are so many SQL queries in a simple web page.  If you test the request time of a form submit in Drupal.org it will always take seconds to finish.  How do you improve the speed of your web site?

Find objects between two dates MongoDB Texstudio + Biber + build folder I used  to export my auxiliary files into a different directory. Basically i just add -aux-directory=build in Options -&gt; Configure -&gt; Commands and added the build folder into Options -&gt; Configure -&gt; Build -&gt; Build Options -&gt; Additional Search Paths -&gt; Log. This succesfully generates all the auxilliary files in the build folder and it's also possible to generate the pdf. Unfortunately biber has a problem with this setup:  Prozess gestartet: biber.exe &quot;MyFile&quot; INFO - This is Biber 1.7 INFO - Logfile is 'MyFile.blg' ERROR - Cannot find control file 'MyFile.bcf'! - did you pass the &quot;backend=biber&quot; option to BibLaTeX?

Determining application path in a Python EXE generated by pyInstaller What is the path of an MTP device in Windows? I am running Windows XP and have a phone mounted through USB by MTP.  In Explorer, its address is:  My Computer\SAMSUNG-SGH-I547\Phone\DCIM   I would like to execute a command line command such as  explorer "My Computer\SAMSUNG-SGH-I547\Phone\DCIM\Camera"   so as to quickly go to the Camera folder. (Right-clicking the device or anything in it does NOT provide a "Create Shortcut" dialog.)  But "My Computer" is not a valid PATH in Windows. Unlike USB flash drives, it seems the phone mounted by MTP does not get a letter drive name.  So, what is the path of an MTP device in Windows?  If the answer is there is no command line path, is there workaround? If $\omega \in \Omega^q(M)$, and $(\omega|_{U})_p = 0$, is $\omega_p = 0$? How do I get my device detected by ADB on Linux? I just got my shiny new Wileyfox Swift – and before putting it to use I want to oem unlock and root it (as I usually do with new devices ;) Trouble is, though  is enabled on the device, and a corresponding line in /etc/udev/rules.d/51-android.rules exists, the device is not seen by adb devices.  I know there are several answers scattered around this site, but they are either hard to find, just cover a specific device, or don't cover all steps I finally needed. So I take this as a chance for a canonical, device-independent question and give it a detailed answer below:  How can I get my Android device seen and used by adb on Linux? Why don't electrons crash into the nuclei they "orbit"? If $g \circ f$ is surjective, show that $f$ does not have to be surjective? Suppose $f: A \to B$ and $g: C \to D$ are functions, and that $B ⊆ C$.  I need to come up with an example where $g \circ f$ is surjective but $f$ is not. I'm confused on how exactly to do that, but I understand that to show something is surjective you have to have the range of the function equal to the codomain of the function. Here's my attempt:  So if $g(x) = x^2$ with a codomain of $ℝ$, and $f(x) = \sqrt{x}$ with a codomain of $ℝ$, then $g(f(x)) = (\sqrt{x})^2 = x$. Since the range of this function and codomain are the same, this is surjective.  But, since $f(x) = \sqrt{x}$, its range is only $[0, ∞)$, which is smaller than its codomain of $ℝ$, meaning $f$ is not surjective. Let $a$, $b$, and $c$ be complex numbers with $a\neq0$. Show that the solutions of $az^2+bz+c=0$ are $z_1,z_2=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$, just as they are in the case when $a$, $b$, and $c$ are real numbers. How to install Android Studio on Ubuntu? Please tell me the full process of installing Android Studio and its necessary dependencies. This is a comic book I read no later than 1993 (so is pre-1993).  And probably after 1988 though I can't be certain.  The protagonist is a huge barbarian with an axe, who seems like an old man, who is defending a series of gigantic walls against an invading army, apparently single-handedly. They keep having to fall back to inner walls. He has to get a massage at one point (not that kind of comic btw).  It's not a super-hero or funny comic, it's more of a serious graphic novel.  That's about it, sorry it's so vague. Is there even an automatic ban on meta? Somewhere I heard the automatic question ban on Meta is set lower than on the main site. But looking at the profile of  it looks like there is absolutely no automatic ban on meta.  Is this intended behaviour? Prove that any continuous map on $\mathbb{R}$ which is the identity on $\mathbb{Q}$ is the identity map, hence Aut$(\mathbb{R}/\mathbb{Q})= 1.$  proof: Suppose $\sigma$ is continuous on $\mathbb{R}$ which is an identity on $\mathbb{Q}$. let $a \in R $. Then since $\sigma$ is continuous, then by definition there is $\delta_1 &gt; 0$ such that $|a - b| &lt; \delta_1$.  And assume $|\sigma(a) -\sigma(b)| &lt; \epsilon/2$ .  Let $\delta $= min{$\epsilon/2, \delta_1$}.  And now let $b \in \mathbb{Q}$ such that $|a - b| &lt; \epsilon$. Then  $|\sigma(a) - a| = |\sigma(a)  - b + b - a| \leq |\sigma(a) - \sigma(b) | + |b - a| &lt; \epsilon/2 + |b-a|$.  Can someone please help me? I am not sure . Can I say $|b - a| &lt; \epsilon/2 $?

I have just bought a new computer and I have everything migrated over except for my Steam games.  I looked in Program Files/Steam/ and I found a folder full of the games I have downloaded, but I do not know if it is safe to just copy these folders from one computer to another (seeing as a lot of other applications will not work if you do this), or is there another recommended way?  I don't really feel like re-downloading all my games. I don't have the time nor bandwidth to download 20GB over a 1.5mbps connection.  Is it possible to contact Valve and get a disk with the games on it?
