Here's one to get shot down: How about letting bounties to be set using the reputation gained through the use of another site? So, for instance, I'm a programmer with a high Stack Overflow rep who hates using computers. Wouldn't it be useful for me to be able to exchange some of my excess Stack Overflow credit to incentivise a question on Super User?   Or perhaps I'd like to highlight a question on Meta Stack Overflow, but I don't spend my time there. According to :     By looking for trades that take place in between the bid and ask, you   can tell when a strong trend is about to come to an end. This is   because these trades are often placed by large traders who take a   small loss in order to make sure that they get out of the stock in   time.   A trader when buying needs to buy at the ask price and when selling needs to sell at the bid price. So how can a trade happen 'in between' the bid and ask? You see him for a split second in the final scene with the Final Order and he has kind of a white beard. I can't find any reference online except Nien Nunb from ROJ. Single question thread with multiple questions, some duplicates I've recently run into many questions where to author asks several related questions in one post, many of them asked before.   I'm wondering what out policy is on such questions:   Should I vote-close them as being not constructive? Should I vote-close them as duplicates? Should I leave them be? Or even suggest an answer?    - Each of the questions: Waiting for an AJAX request with selenium, and headless browsing in selenium have been asked here before, but he asked both in one.  I've done my best to search for similar questions here in meta but I was unable to find any, reading appreciated.

Fourier series of Log sine and Log cos Last month, I was travelling on a backpacking trip across Russia and the Baltic states (Schengen zone). I'm an Indian by nationality. So I had to get the respective single entry visa for Russia and Schengen Europe.  At the border crossing into Estonia by road (at Ivangorod-Narva), I exited the Russian border with an exit stamp (so now I can't go back to Russia since I had a single entry visa). When I was at the immigration checkpoint of Estonia, I was heavily questioned on the intent of my travel to Europe while entering Estonia by road.   Though I finally got into Europe, It got me wondering - what happens if a foreign national is denied entry into a country not at the airport but by land between 2 countries he cannot go into ?  Generally, if you are denied entry at the airport the airline has the obligation to fly you back to your country. But what happens when you are stuck between two countries and you cant get into either ? What happens to you then ? extract the 4th column from a csv file using unix command I have a csv file formatted as below.  "col1","col2","col3","col4" "1","text1","&lt;p&gt;big       html      text&lt;/p&gt; ","4th column" "2","text2","&lt;p&gt;big2       html2      text2&lt;/p&gt; ","4th column2"   I want to extract the 4th column using.  I think that awk is the best tool for this ( let me know if I am wrong). I tried this   awk -F, '{print $4}' myFile.csv    but it fails.  I think because the 3rd column is multiline one.  How can I use awk or any other unix command to extract the 4th column.  I am looking for an efficient solution since my real file is big (> 2GB) I'm new to Linux and Ubuntu. People keep using ~/filename in their answers to my questions. What does ~/ mean? How to remove "phone style" Gnome swipe to unlock I need to remove the annoying new "locking" screen that shows a giant clock: I can't remove it with just moving the mouse (as with any other desktop environment), the animation is slow, and it isn't asking me for a password!  I managed to disable it, just to discover that now I can't lock my screen on purpose, so I can't go away from the computer.  Just to clarify, I want to:   After some time the screen could go black, but if I move the mouse or press any key then I can use it directly (like a normal screensaver). If I press super-L then it is locked, and I must type the password to unlock (like a normal lock screen).   I found several "solutions", but none seems to work: How do I write content to another browser window using Javascript? I've opened a new window with window.open() and I want to use the reference from the window.open() call to then write content to the new window.  I've tried copying HTML from the old window to the new window by using myWindow.document.body.innerHTML = oldWindowDiv.innerHTML; but that's doesn't work.  Any ideas? How does ZFC describe addition? Surprisingly, the Wikipedia article on addition doesn't contain the answer. I looked  elsewhere online for it, but didn't find it.   Intuitively, the cardinal of the union of two sets seemed appealing. But that approach doesn't work, given that the union of 2 and 2 is 2. I wondered whether ordered sets might be essential to the answer.   So, how does ZFC describe addition? Giving a single user write permissions I want to grant a single user write permissions to a directory owned by root over command line. With chmod, it seems that I can only change the permissions for owner, group and other, not for a specific user.

Screenshots for reference: Why doesn't LaTeX hyphenate words containing accents, e.g. "développement"? In this MWE, Latex doesn't hyphen the word "développement" and prefer to create a HUGE hbox.   \documentclass[a4paper,12pt,dvipsnames]{report} \usepackage[utf8]{inputenc} \usepackage[french]{babel} \usepackage{lmodern} \usepackage[a4paper, showframe]{geometry}  % Title Page \title{} \author{}   \begin{document} \section{Section}  \subsection{Subsection} \begin{description}  \item [Marhalie Toucse : ]  ingénieure de la plate-forme SORTATZ.
