  • How to automatically print the contents of a folder in OS X?

    - by MDRoz
    I would like to be able to set up a folder on my Mac, where I could dump files and have them be automatically sent to the default printer. This way I would be able to print files at home when I'm not physically at home, using something like Dropbox. It wouldn't have to be real-time; i.e., a scheduled job that checks the folder every so often would be acceptable. What's the easiest approach? Automator? Applescript? Cron job?

  • Java: Switch statements with methods involving arrays

    - by Shane
    Hi guys I'm currently creating a program that allows the user to create an array, search an array and delete an element from an array. Looking at the LibraryMenu Method, the first case where you create an array in the switch statement works fine, however the other ones create a "cannot find symbol error" when I try to compile. My question is I want the search and delete functions to refer to the first switch case - the create Library array. Any help is appreciated, even if its likely from a simple mistake. import java.util.*; public class EnterLibrary { public static void LibraryMenu() { java.util.Scanner scannerObject =new java.util.Scanner(System.in); LibraryMenu Menu = new LibraryMenu(); Menu.displayMenu(); switch (scannerObject.nextInt() ) { case '1': { System.out.println ("1 - Add Videos"); Library[] newLibrary; newLibrary = createLibrary(); } break; case '2': System.out.println ("2 - Search Videos"); searchLibrary(newLibrary); break; case '3': { System.out.println ("3 - Change Videos"); //Change video method TBA } break; case '4': System.out.println ("4 - Delete Videos"); deleteVideo(newLibrary); break; default: System.out.println ("Unrecognized option - please select options 1-3 "); break; } } public static Library[] createLibrary() { Library[] videos = new Library[4]; java.util.Scanner scannerObject =new java.util.Scanner(System.in); for (int i = 0; i < videos.length; i++) { //User enters values into set methods in Library class System.out.print("Enter video number: " + (i+1) + "\n"); String number = scannerObject.nextLine(); System.out.print("Enter video title: " + (i+1) + "\n"); String title = scannerObject.nextLine(); System.out.print("Enter video publisher: " + (i+1) + "\n"); String publisher = scannerObject.nextLine(); System.out.print("Enter video duration: " + (i+1) + "\n"); String duration = scannerObject.nextLine(); System.out.print("Enter video date: " + (i+1) + "\n"); String date= scannerObject.nextLine(); System.out.print("VIDEO " + (i+1) + " ENTRY ADDED " + "\n \n"); //Initialize arrays videos[i] = new Library (); videos[i].setVideo( number, title, publisher, duration, date ); } return videos; } public static void printVidLibrary( Library[] videos) { //Get methods to print results System.out.print("\n======VIDEO CATALOGUE====== \n"); for (int i = 0; i < videos.length; i++) { System.out.print("Video number " + (i+1) + ": \n" + videos[i].getNumber() + "\n "); System.out.print("Video title " + (i+1) + ": \n" + videos[i].getTitle() + "\n "); System.out.print("Video publisher " + (i+1) + ": \n" + videos[i].getPublisher() + "\n "); System.out.print("Video duration " + (i+1) + ": \n" + videos[i].getDuration() + "\n "); System.out.print("Video date " + (i+1) + ": \n" + videos[i].getDate() + "\n "); } } public static Library searchLibrary( Library[] videos) { //User enters values to setSearch Library titleResult = new Library(); java.util.Scanner scannerObject =new java.util.Scanner(System.in); for (int n = 0; n < videos.length; n++) { System.out.println("Search for video number:\n"); String newSearch = scannerObject.nextLine(); titleResult.getSearch( videos, newSearch); if (!titleResult.equals(-1)) { System.out.print("Match found!\n" + newSearch + "\n"); } else if (titleResult.equals(-1)) { System.out.print("Sorry, no matches found!\n"); } } return titleResult; } public static void deleteVideo( Library[] videos) { Library titleResult = new Library(); java.util.Scanner scannerObject =new java.util.Scanner(System.in); for (int n = 0; n < videos.length; n++) { System.out.println("Search for video number:\n"); String deleteSearch = scannerObject.nextLine(); titleResult.deleteVideo(videos, deleteSearch); System.out.print("Video deleted\n"); } } public static void main(String[] args) { Library[] newLibrary; new LibraryMenu(); } }

  • How to read back and print text with newlines from a Python (Django) string with HTML?

    - by user1801486
    If someone types in a phrase, such as: I see you driving round town with the girl I love, and I’m like: haiku. (no blank lines between each line, but the text is written on three separate lines) into a text box on a web page, and then presses a button which is then stored in a database via Django, and that string is read back and printed on a page, how can I get it to print on an HTML page with the newlines still in the text? So instead of it being printed back as: I see you driving round town with the girl I love, and I’m like: haiku. It would print as: I see you driving round town with the girl I love, and I’m like: haiku. I know that if I use: (textarea)soAndSo.body(/textarea), this preserves the newlines that were in the file when the user typed it up originally. How can I get this same effect, but without having to use textarea boxes?

  • Generating a python file

    - by fema
    Hi! I'm havin issues with python (imo python itself is an issue). I have a txt file, it contains a custom language and I have to translate it to a working python code. The input: import sys n = int(sys.argv[1]) ;;print "Beginning of the program!" LOOP i in range(1,n) {print "The number:";;print i} BRANCH n < 5 {print n ;;print "less than 5"} The wanted output looks exactly like this: import sys n = int(sys.argv[1]) print "Beginning of the program!" for i in range(1,n) : print "The number:" print i if n < 5 : print n print "less than 5" The name of the input file is read from parameter. The out file is out.py. In case of a wrong parameter, it gives an error message. The ;; means a new line. When I tried to do it, I made an array, I read all the lines into it, split by " ". Then I wanted to strip it from the marks I don't need. I made 2 loops, one for the lines, one for the words. So then I started to replace the things. Everything went fine until it came to the } mark. It finds it, but it can not replace or strip it. I have no more idea what to do. Could someone help me, please? Thanks in advance!

  • Filtering string in Python

    - by Ecce_Homo
    I am making algorithm for checking the string (e-mail) - like "E-mail addres is valid" but their are rules. First part of e-mail has to be string that has 1-8 characters (can contain alphabet, numbers, underscore [ _ ]...all the parts that e-mail contains) and after @ the second part of e-mail has to have string that has 1-12 characters (also containing all legal expressions) and it has to end with top level domain .com EDIT email = raw_input ("Enter the e-mail address:") length = len (email) if length > 20 print "Address is too long" elif lenght < 5: print "Address is too short" if not email.endswith (".com"): print "Address doesn't contain correct domain ending" first_part = len (splitting[0]) second_part = len(splitting[1]) account = splitting[0] domain = splitting[1] for c in account: if c not in "abcdefghijklmopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_.": print "Invalid char", "->", c,"<-", "in account name of e-mail" for c in domain: if c not in "abcdefghijklmopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789_.": print "Invalid char", "->", c,"<-", "in domain of e-mail" if first_part == 0: print "You need at least 1 character before the @" elif first_part> 8: print "The first part is too long" if second_part == 4: print "You need at least 1 character after the @" elif second_part> 16: print "The second part is too long" else: # if everything is fine return this print "E-mail addres is valid" EDIT: After reproting what is wrong with our input, now I need to make Python recognize valid address and return ("E-mail adress is valid") This is the best i can do with my knowledge....and we cant use regular expressions, teacher said we are going to learn them later.

  • How can you prevent a window being captured by Print-Screen?

    - by John
    I noticed a few times than when I print-screen while Media Player is running, the content is replaced with a grey rectangle. I've no idea if it's deliberate due to DRM, or some technical issue, but it struck me that being able to deliberately block screen-capture might be a useful feature in some scenarios. Is there some specific message each HWND gets for print-screen - does Windows do a special repaint or simply dump buffers to the clipboard? I guess I'd prefer to focus this on Win32 specifically, but as long as it's Windows-related then fine.

  • How can I save/print values in my WATCH list in Visual Studio 2008?

    - by Rising Star
    When I attach the Visual Studio 2008 debugger to my web server process, I sometimes browse a large amount of data in my watch list. Suppose I have an array of string variable that I expand to show 20 entries. It seems that the only way to save these values is to copy and paste them one at a time. I have gone so far as to do a screen-shot in order to have a record of what the values were (to refer to later or print a hard copy). Is there an easy way to save and print these values? I am familiar with the new "IntelliTrace" feature in Visual Studio 2010 Ultimate, but it seems overkill for this purpose. I just want to take something like an array of strings and save it for later reference once I've stopped the debugger. What's a good way to do this?

  • Linux How to print all the files with the same prefix after searching for them?

    - by Alyx
    I need to search through a directory which contains many sub directories, each which contain files. The files read as follows question1234_01, where 1234 are random digits and the suffix _01 is the number of messages that contain the prefix, meaning they are apart of the same continuing thread. find . -name 'quest*' | cut -d_ -f1 | awk '{print $1}' | uniq -c | sort -n example output: 1 quest1234 10 quest1523 This searches for all the files then sorts them in order. What I want to do is print all the files which end up having the most occurrences, in my example the one with 10 matches. So it should only output quest1523_01 - 11

  • : for displaying all elements in a multidimensional array in python 3.1.

    - by Leif Andersen
    I have a multidimensional array in python like: arr = [['foo', 1], ['bar',2]] Now, if I want to print out everything in the array, I could do: print(arr[:][:]) Or I could also just do print(arr). However, If I only wanted to print out the first element of each box (for arr, that would be 'foo', 'bar'), I would imagine I would do something like: print(arr[:][0]) however, that just prints out the first data blog (['foo', 1]), also, I tried reversing it (just in case): print(arr[0][:]) and I got the same thing. So, is there anyway that I can get it to print the first element in each tuple (other than: for tuple in arr: print(tuple[0]) )? Thanks.

  • How to disable/destroy forever Chrome's "print preview" option?

    - by VeryVito
    This question seems to come up a lot (pretty much every time a new version of Chrome is released). Previous answers such as these no longer apply (or don't work for Mac), however: How do I get the "old style" system print dialog for Chrome on Windows? Disable Chromes Ctrl+P handling of printing Sadly, Google seems intent on shoving this broken preview screen down our throats (The thought of someone not want to use their nonstandard, feature-poor alternative to a systemwide service is inconceivable to them, apparently), and the "disable" flag no longer seems to exist in recent versions. Anyone know how to disable it in modern versions of the browser, which no longer include this option under "chrome://flags?" (OS-X specifically?)

  • Self Modifying Python? How can I redirect all print statements within a function without touching sys.stdout?

    - by Fake Name
    I have a situation where I am attempting to port some big, complex python routines to a threaded environment. I want to be able to, on a per-call basis, redirect the output from the function's print statement somewhere else (a logging.Logger to be specific). I really don't want to modify the source for the code I am compiling, because I need to maintain backwards compatibility with other software that calls these modules (which is single threaded, and captures output by simply grabbing everything written to sys.stdout). I know the best option is to do some rewriting, but I really don't have a choice here. Edit - Alternatively, is there any way I can override the local definition of print to point to a different function? I could then define the local print = system print unless overwritten by a kwarg, and would only involve modify a few lines at the beginning of each routine.

  • Java crashes on lubuntu but not Ubuntu

    - by Echogene
    I have lubuntu and Ubuntu partitions on my drive. I've been having an interesting time with the new lubuntu partition. I've encountered strange things with the game Minecraft, Java and graphics drivers on the lubuntu partition. Firstly, I'll say that Minecraft runs fine at about 60fps on the Ubuntu partition with the latest drivers. (This is lower than it should be as it's a pretty decent graphics card [Radeon HD 5700].) When I first started lubuntu, I tried to see if I could get Minecraft running on Java. Java crashed when loading the main game graphics on both Sun and OpenJDK without proprietary drivers. Java also crashed on both Javas with proprietary drivers after the necessary restart. However, after disabling (with 'remove' button) the proprietary drivers with jockey-gtk in the session after the restart to install the drivers, Minecraft ran very well at ~120fps. This didn't continue after another restart, when it ran at 9fps. After failing thereafter on lubuntu to get it working at 15fps, I tried reinstalling lubuntu and installed the exact same driver (the latest one, not the one appearing on jockey) and Java versions as on Ubuntu. That is, now Ubuntu and lubuntu have the same graphics driver and Java version. Minecraft still crashes in the same way on lubuntu but works fine on Ubuntu. I would appreciate any explanation for any of these events. What differences between lubuntu and Ubuntu could cause this? Edit: After installing the 32bit driver version on lubuntu (seeing as lubuntu is 32bit), I have Java "working" for Minecraft. However, it is at <15fps again and it can't log in to servers as it takes too long.

  • Stack Trace Logger [migrated]

    - by Chris Okyen
    I need to write a parent Java class that classes using recursion can extend. The parent class will be be able to realize whenever the call stack changes ( you enter a method, temporarily leave it to go to another method call, or you are are finsihed with the method ) and then print it out. I want it to print on the console, but clear the console as well every time so it shows the stack horizantaly so you can see the height of each stack to see what popped off and what popped on... Also print out if a baseline was reached for recursive functions. First. How can I using the StackTraceElements and Thread classes to detect automatically whenever the stack has popped or pushed an element on without calling it manually? Second, how would I do the clearing thing? For instance , if I had the code: public class recursion(int i) { private static void recursion(int i) { if( i < 10) System.out.println('A'); else { recursion(i / 10 ); System.out.println('B'); } } public static void main(String[] argv) { recursion(102); } } It would need to print out the stack when entering main(), when entering recursion(102) from main(), when it enters recursion(102 / 10), which is recursion(10), from recursion(102), when it enters recursion(10 / 10), which is recursion(1) from recursion(10). Print out a message out when it reaches the baseline recursion(1).. then print out the stacks of reversed revisitation of function recursion(10), recursion(102) and main(). finally print out we are exiting main().

  • How do I get my graphic card to work properly?

    - by Lucas
    I been having some problems with my graphic card for a time now. But I had enough when I did'nt get Oil Rush to work on my HP Pavilion g6. The system has suggested hardware drivers for me, but the first time I installed them they pretty much fucked up the graphics. After some time I managed to get the computere to work properly (I thought) again. When the game did'nt work I tried to the hardware drivers for the graphic card anyway. First of all there was to possible choices insted of one, as the last time I installed the drivers (when it did'nt work out so good). The choices are: ATI/AMDs proprietary video drivers FGLRX (update for edition) and Proprietary FGLRX-video drivers for ATI/AMD I realized the drivers probebly are pretty much the same, so I tried the first one. But this did'nt work. Instead I was asked to "Look in to /usr/var/log/jockey.log". This did'nt helped me much. Instead I choiced the other one, wich was installed and after reboot there where some changes. First of all there was a lot more details for Unity that was'nt there before and some shortkeys are now working that did'nt before (like Ctrl + T and the Prt Sc-button). But overall everything doesn't work as it used to. Like when you browse between the workspaces it doesn't look the same. To get to the point: it doesn't work well right now even if I got some things better and now will not Oil Rush (as I mentioned in the beginning) even start. SO! Can someone give me any advice with this? I'm stuck. Can't manage to see whats wrong right now. Any help? My graphic card is AMD Radeon HD 6470M.

  • What LPR arguments do I need to print a 1400x800 pixel image on a 4x6 label?

    - by Nick
    This is driving me nuts. UPS sends our system a 1400x800 GIF image of a shipping label, which is supposed to fit nicely on a 4x6 page. Unfortunately, I can't seem to get the command line options right to make it happen. We're using an Eltron/Zebra 2844 with a network adapter, and printing from our Ubuntu 8.04 server using CUPS. We're using the correct drivers, and test pages print correctly. No matter what I try though, it insists on printing the UPS labels accross 6 pages, with a little bit of the label on each page, or way too small. I've tried a bazillion different lpr settings, most of them producing garbage. The closest I've gotten is this: lpr -P Eltron2844 -o natural-scaling=55 -o page-right=0 -o page-left=0 -o landscape -o media="4x6" ./1ZY437560399620027.gif but it causes the image to be too small on the page. It's about an inch too short, and there's a 1/2" margin on both sides. If I bump the scale up to 56, it explodes the image onto two pages, and squashes it. Any ideas?

    Hi, Initially C was used for designing drivers / firmwares and all that. Right now this has been taken over by C++. Ok. Let me not deviate this question. I would like to know where else C++ is being used and how you see its future? You can also list out pros and cons of C++ compared to other languages. Would like to see a healthy and meaningful discussion on C++ current usage and its future?! Cheers! AKN
