On my iMac, when one pushes certain character keys after about 1 second a menu appears with the selected character with diacritic marks (accents) - i.e. when one presses S, one is presented with a menu showing ß ś š. You can then choose to insert one of these characters using the numerical keys (i.e. pressing S ... short wait ... press 1 results in a ß).    (I'm not sure if this is the default macOS behaviour, or a setting for my Mac. The keyboard in System Preferences implies that holding a key should repeat that key because it has "Key Repeat" and "Delay Until Repeat" settings.)  Is it possible to decrease this wait time? I've been typing in German a lot recently, and ending up with a4 in my text when I intend to write ä.
Does anyone know how to make the character picker appear more quickly?   I use it enough now in my German language studies that it has become second nature for the critical marks and much faster than using the alt+keypress shortcuts.   Only problem is that it's so second nature that sometimes it doesn't pop up quickly enough so I end up typing the character and the number shortcut sometimes (IE u2 instead of ü). Anyone know how to make it appear with less delay? Ideally, I'd love if I could just hold the character and press the number but it appears that OSX insists on waiting for the menu to pop up.
How to execute consecutive commands from history? Suppose I want to execute a sequence of four commands that I have executed before. If the first one is 432 in the command-history, then I could do:  $ !432; !433; !434; !435   I'm curious, is there a more efficient way to accomplish this? Why does the default Object.toString() include the hashcode? How to create a Windows 7 installation USB from OS X? I'm trying to create a Windows 7 installation USB (for use on a PC) from OS X.  I've tried following these instructions from a :   Insert the USB flash drive and run the command diskutil list to find out the disk name, we'll use /dev/disk1 as an example Now unmount the disk using diskutil unmountDisk /dev/disk1 dd if=/path/to/Win7.iso of=/dev/disk1 bs=8192   But the instructions don't work. When I insert the created USB drive into my PC and try to boot from it, I get this message:     Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key   What am I missing? Find all $x$ such that $x^6 = (x+1)^6$. Turning off and on images in figures Is it possible to prevent the contents of a figure from being rendered? I have a large book document, and to speed up compiling while working on a draft, I would like to have some way of ignoring the content of the images, but ensuring that the figure size remains.  In several cases I am using a line like:  \includegraphics[width=\linewidth]{figure.pdf}     so I do not know the actual size of the image. Do I need to play previous Witchers before Witcher3 I'm thinking about buying The Witcher 3 and I know it's heavily based on a story/narrative.   For the story/narrative to make sense, do I need to play the previous 2 Witcher games - or are the stories for each title independent of one another? I've just created an account to submit an application to the Ubuntu Software Centre and the agreement says: "You are responsible for determining applicable taxes in connection with distributing your App, and you shall pay applicable taxes to the applicable tax authorities.".  Does this mean that Canonical doesn't collect tax (especially VAT in the EU) and it's my responsibility to do it?   Also, am I wrong to assume that the price listed by the USC is the same for both people who pay taxes and for those who don't need to pay them? What really allows airplanes to fly? I have made some changes to a file which has been committed a few times as part of a group of files, but now want to reset/revert the changes on it back to a previous version.   I have done a git log along with a git diff to find the revision I need, but just have no idea how to get the file back to its former state in the past. I am following Carroll's GR book. He explain that it is convention to parameterize geodesics of photons by a parameter $\lambda$ such that  $$p^\mu ~=~ \frac{d x^{\mu}}{d \lambda}.\tag{3.62}$$  But this is the definition of 4-velocity for a massive particle in the case of $\lambda=\tau$ equal to proper time. My question then, is $$u^\mu = p^\mu$$ for all massless particles? I ask because it's well-known that proper time $\tau$ freezes for massless particles. How does the subject-verb agreement work when a singular noun describes a plural one? Of the following, which sentence is righter?  The computers is a good choice. The computers are a good choice.

I am an Indian citizen and have applied for the Standard Visitor visa to the UK, and wish to travel to Ireland by using the BIVS scheme.    Do I need to fill up a separate application for BIVS endorsement or is it handed out automatically?  Also, If I enter the UK, and then travel to Ireland, can I re-enter the UK again? I know the  processors have been around for a long time and are mostly used in servers, but I am curious, why do people not use the Xeons in a high performance desktop?    As far as I know about the best desktop processor out there now is the  line. The i7's and Xeons are both quad-core processors, what is the main difference in these? I just saw that the MacBook Pro's are using the quad core Xeons instead of the i7's. How do I mount shared folders in Ubuntu using VMware tools? MacBook Pro locked with Find My Mac and won't let me boot Independent Edit/Object mode in splitscreen Why is orbital angular momentum not 0 when spin and linear momentum are not collinear?   Why can it be 0 when spin and linear momentum are parallel?  Like in the example of a scalar field at rest decaying into an electron and a positron via interaction $\frac{1}{2}g\phi \bar{\Psi}\Psi $   If spin is along x axis and three-momenta is along z axis, decay rate will be 0 if two spins are opposite because orbital momentum is not 0 after decaying. Proving that $e^{\pi}-{\pi}^e\lt 1$ without using a calculator Prove that $e^{\pi}-{\pi}^e\lt 1$ without using a calculator.    I did in the following way. Are there other ways?  Proof : Let $f(x)=e\pi\frac{\ln x}{x}$. Then,  $$e^{\pi}-{\pi}^e=e^{f(e)}-{e}^{f(\pi)}\tag1$$ Now, $$f'(x)=\frac{e\pi(1-\ln x)}{x^2},\quad f''(x)=\frac{e\pi (2\ln x-3)}{x^3},\quad f'''(x)=\frac{e\pi (11-6\ln x)}{x^4}.$$ Since $f'(x)\lt 0$ for $e\lt x\lt\pi$, one has $f(e)\gt f(\pi)$. By , there exists a point $c$ in $(e,\pi)$ such that  $$\begin{align}f(\pi)&amp;=f(e)+(\pi-e)f'(e)+\frac{(\pi-e)^2}{2}f''(c)\\&amp;\gt f(e)+(\pi-e)\cdot 0+\frac{(\pi-e)^2}{2}\cdot \frac{e\pi(2\ln e-3)}{e^3}\\&amp;=f(e)-\frac{\pi(\pi-e)^2}{2e^2}\tag2\end{align}$$ because $f'''(x)\gt 0\ (e\lt x\lt \pi)$ implies $f''(c)\gt f''(e)$.  By the  and $(2)$,  $$e^{f(e)}-e^{f(\pi)}\lt (f(e)-f(\pi))e^{f(e)}\lt \frac{\pi (\pi-e)^2}{2e^2}\cdot e^{\pi}=\frac{e\pi(\pi-e)^2}{2}\cdot e^{\pi-3}\tag3$$  Since $e^x\lt \frac{1}{1-x}\ (0\lt x\lt 1)$ and $0\lt \pi-3\lt 1$,  $$e^{\pi-3}\lt\frac{1}{4-\pi}\tag4$$  From $(1)(3)(4)$,  $$e^{\pi}-{\pi}^e\lt \frac{e\pi(\pi-e)^2}{2}\cdot\frac{1}{4-\pi}\lt\frac{3\times\frac{22}{7}\left(\frac{22}{7}-2.718\right)^2}{2}\cdot\frac{1}{4-\frac{22}{7}}\lt 0.993\lt 1$$ How to create a label combining different font sizes or types?
