PHP substring not working for intergers
Zero-pad digits in string
I know references are syntactic sugar, so code is easier to read and write. But what is the difference between a pointer variable and a reference variable? setSystemUiVisibility(SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION) does not work Learn Bayesian inference applied to astronomy / astrophysics? I'm using pdfLatex (with --shell-escape option) and I had a problem of compilation with TexWorks that was successfully solved with the help of other post in this site: .  After correcting that error the code compiles smoothly but just displays the logarithmic grids, not the function. The gnuplot files are created in the right place, but the graphic doesn't come out in the PDF.  Code from :  \documentclass{article}  \usepackage{tikz} \usepackage{bodegraph}  \begin{document}  \begin{tikzpicture}[     gnuplot def/.append style={prefix={}}, % Fixed the issue (prefix was 'gnuplot/\jobname/' before) ] \begin{scope} \UnitedB \semilog{-1}{2}{-50}{60}  \BodeAmp{-1:1.35}{\POAmpAsymp{4}{2.0}+\IntAmp{1}}  \end{scope} \end{tikzpicture} \end{document}   Any clues? I'm making a call:  myResult = MakeMyCall(inputParams, out messages);   but I don't actually care about the messages.  If it was an input parameter I didn't care about I'd just pass in a null.  If it was the return I didn't care about I'd just leave it off.    Is there a way to do something similar with an out, or do I need to declare a variable that I will then ignore? in a file containing :  ... 18-11-2018:othercharacters 10-11-2018:othercharacters 03-10-2018:othercharacters 30-10-2018:othercharacters 27-09-2018:othercharacters 03-12-2018:othercharacters ...   the command :  sort -t- -k2 -k1    does not sort by date, what am I missing ? Book: World covered in trees that are miles high Torque relationship to speed in a DC motor I have a conceptual doubt about torque-speed relation in a DC motors. It's probably a gap in my thinking but I'm posting this question anyway.  Torque and speed in a DC motor are said to be inversely proportional. But doesn't an increase in torque result in increase in Angular Acceleration and consequently, angular speed?  I know that back EMF/counter-EMF is responsible for the inverse relation but it seems counter intuitive to me. What happens to the angular acceleration, angular speed when the torque is increased and where does all that work go? What do you call a person who is utterly independent and a loner? Hamiltonian Monte Carlo for dummies Could you provide a step-by-step for dummies explanation of how Hamiltonian Monte Carlo work?  PS: I've already read the answers here, , and here, , and here,  and they do not address it in a step-by-step way. Is "reserved" an adjective or verb in this example? I need an answer about this sentence please:     We had a reserved seat.   Reserved in this sentence is a verb. I read that in a morphology book.  My question is: how does this become a verb?  I thought it was an adjective. Where can I find computer modern fonts for use in other programs, e.g. Adobe Illustrator? For some complicated diagrams, I need to use something like Adobe Illustrator or Inkscape, and would like to include nicely typeset labels. (I'm aware of post-processing solutions, such as pinlabel.) One way to do this is to use a closely-matching font, and then convert fonts to outlines. Better, however, would be to use Computer Modern directly in Illustrator.  Where can I find a Computer Modern font compatible with Adobe Illustrator? Before we launched our website, we had set up a "coming soon" page and google picked up the title and description from its contents. So the description in the search results said:     Coming soon! Visit example.org for updates.   It's been a few weeks since we launched our website. We've even created a sitemap and submitted it to Google. In Google Search Console, the pages have been crawled and all the pages are appearing as expected on Google, EXCEPT the homepage which is still not updated! The title and description of the homepage in google search results still says "coming soon.".***  I checked on bing too, but it appears to be fine there.  All other pages seem to be indexed fine on Google. I don't even have any crawl errors in my reports. So what seems to be the problem? I've already waited for 2 weeks. "Less" vs. "fewer" I've just received a memo which says (effectively)      As more people leave, there will be less people available.   I want that word to be fewer. Are there guidelines for which word ought to be used when? Can I use Wubi for manual installation? Is it possible to use Wubi for Ubuntu 13.04? I read that it will not be supported in the official release due to some problems. Is this going to change in the future, and can we expect to see a future release with support for 13.04? The Quotation Mark character in TeXworks editor has vanished Now, my version of TeXworks is 0.4.5r.1280 and I can't have the " character on the keyboard.    I have ``  or '' instead. Why?  And It's the same with Alt+034. I'm very disappointed with that. Does Power Word Kill kill druids in wild-shape? I think these terms almost refer to the same thing, when used loosely:   terminal shell tty console   What exactly does each of these terms refer to? Does it make a difference if your URL path ends in a trailing slash or not? Does it make any difference to SEO ratings what-so-ever if your url has a trailing slash:  http://www.example.com/some/slug/paths/   as opposed to one that does not:  http://www.example.com/some/slug/paths Reducing resolution of huge categorical raster in QGIS?
