Using the GET parameter of a URL in JavaScript
How to retrieve GET parameters from JavaScript
A smooth vector field on $S^2$ vanishing at a single point How do I shrink the partition of an img file made from dd? UnboundLocalError: local variable 'url_request' referenced before assignment How can I find such a $z$? (Injectivity of $T(z) = \lambda z + \mu\bar{z}$) We consider $T:\mathbb{C}\to\mathbb{C}$ defined by $T(z)=\lambda z+\mu\overline{z}$, where $\lambda ,\mu\in\mathbb{C}$. I want to prove that if $T$ is injective, then $\lambda\cdot\overline{\lambda}\neq\mu\cdot\overline{\mu}$.  Clearly, if $\mu =0$, then $\lambda\neq 0$ because $T$ is injective.  Now, if $\lambda\cdot\overline{\lambda}=\mu\cdot\overline{\mu}$ and $\mu\neq 0$, then I wanted to find a $z\in\mathbb{C}\setminus\{0\}$ such that $z=-\dfrac{\overline{\lambda}}{\overline{\mu}}\overline{z}$, because we would have that:  $T(z)=-\lambda\dfrac{\overline{\lambda}}{\overline{\mu}}\overline{z}+\mu\overline{z}=\overline{z}(-\lambda\dfrac{\overline{\lambda}}{\overline{\mu}}+\mu)=0$  ('Cause this would prove that $\lambda\cdot\overline{\lambda}=\mu\cdot\overline{\mu}$ implies $T$ is not injective.)  So, the question is, can we always find such a $z\in\mathbb{C}\setminus\{0\}$? Recently I commented on  question   and the text did got bold but the italic word didn't seem to get italic on Android Chrome(Latest Ver.), but when I saw from the PC browser, it rendered as it should...  I've attached a screenshot of my phone ... Cost increase and suspend How do I preload a program for faster start? Is it possible to "preload"(actually not preload, but kinda emulate the startup) e.g. nautilus (or firefox) startup at login, so the first time I launch it myself it launches faster? Probably to start it on another desktop and close after some seconds? SE Android app for tablet has bad formatting on feed The lines wrap so much on v1.0.85 that only a few items can be displayed.  Edit: This is on the world's most low end tablet, Azpen A727.  Screenshots of the old:    and new, showing loss of quality Get latest Flash player on Ubuntu tikz relative coordinates How do I extract a single chunk of bytes from within a file? There's vs There are Run a Windows Service as a console app How do I bind the tmux prefix to a Super? I find even Ctrl+b to be very emacs like but I understand the point. I'm wondering if I could bind it to a single keypress of a key I don't other wise use? namely Super_L (also known as the left windows key. for why I say Super_L start xev in a terminal and press that key) How do I remove any Ubuntu brand and trademark from my Ubuntu install? I am running Ubuntu 17.10 and I would like to build a completely de-branded ISO of it. This means not just dropping the Ubuntu name from /etc/lsb_release but also deleting references in the text of the installation program, in the "about this computer" screen and so on.  I've already checked other questions but I do not consider them duplicate because:    is very old and it just turned into a bunch of "try this tool" suggestions  is also old and suggests a tool called relinux that hasn't seen updates in years  does mention APT packages (and I know how this works) but not trademarks   Therefore my questions are:   Starting from a stock Ubuntu 17.10 (or an official derivative), how can I remove references to the Ubuntu trademark and logo? What exact packages do I need to uninstall? Are there images I need to replace? Are there files I need to edit other than /etc/lsb_release?   Please note that I am not interested in removing other names such as Firefox. I am only interested in the name of the distro. Can Hydrogen Fusion via CNO Cycle Occur in First Generation Stars CNO cycle requires the presence of carbon, nitrogen and oxygen to undergo hydrogen fusion. Does this mean that for first generation stars, no matter how big they are, can't undergo hydrogen fusion by CNO cycle because there is no carbon, nitrogen and oxygen present?   I can't seem to find any website which mentions this. All they say is if a star is large enough, it will undergo hydrogen fusion via CNO cycle, they don't specifically mention it having to be a second generation star. I just got a short algorithm on my page, and it keeps getting aligned at the center of the page. But I want to have it aligned at the top, what do I have to do? Can I use an "if" clause without "then"? Determining application path in a Python EXE generated by pyInstaller I have an application that resides in a single .py file.  I've been able to get pyInstaller to bundle it successfully into an EXE for Windows.  The problem is, the application requires a .cfg file that always sits directly beside the application in the same directory.  Normally, I build the path using the following code:  import os config_name = 'myapp.cfg' config_path = os.path.join(sys.path[0], config_name)   However, it seems the sys.path is blank when its called from an EXE generated by pyInstaller.  This same behaviour occurs when you run the python interactive command line and try to fetch sys.path[0].  Is there a more concrete way of getting the path of the currently running application so that I can find files that are relative to it? It is often stated that the Lagrangian formalism and the Hamiltonian formalism are equivalent.   We often hear people talk about eigenvalues of Hamiltonians but I have never ever heard a word about eigenvalues of Lagrangians.   Why is this so? Is it not useful? is it not possible to do it?
