  • jQuery: How can I check if a block in my document is inside the viewport or outside of it?

    - by Jannis
    I am basically trying to trigger a function if the footer is inside the viewport. How can I check whether the footer is currently visible in the viewport? I assume I will have to put it into the $(window).scroll() event so that the listener becomes true once the footer becomes visible but what the function should be I just can't figure out. Any help would be much appreciated. Thanks for reading, Jannis

  • Fetch excerpt from Wikipedia article?

    - by Felix
    I've been up and down the Wikipedia API, but I can't figure out if there's a nice way to fetch the excerpt of an article (usually the first paragraph). It would be nice to get the HTML formatting of that paragraph, too. The only way I currently see of getting something that resembles a snippet is by performing a fulltext search (example), but that's not really what I want (too short). Is there any other way to fetch the first paragraph of a Wikipedia article than barbarically parsing HTML/WikiText?

  • Python dealing with dates and times

    - by randombits
    I'm looking for a solution to the following: Given today's date, figure out what month was before. So 2 should return for today, since it is currently March, the third month of the year. 12 should return for January. Then based on that, I need to be able to iterate through a directory and find all files that were created that month. Bonus points would include finding the most current file created for the previous month.

  • How do you access/configure summaries/snippets in Django Haystack

    - by mlissner
    I'm working on getting django-haystack set up on my site, and am trying to have snippets in my search results roughly like so: Title of result one about Wikis ...this special thing about wiki values is that...I always use a wiki when I walk...snippet value three talks about wikis too...and here's another snippet value about wikis. I know there's a template tag for highlighting, but how do you generate the snippets themselves? I know Solr generates these, but I can't figure out how to get them from Haystack.

  • Soon to be PhD in Computer Science - Which Path to Follow?

    - by mttr
    I am going to submit my PhD thesis within the next six months. My PhD is on managing the availabiity of large-scale distributed systems, so I have some experience actually building non-trivial systems (+ I have four years experience working as a programmer). I am now trying to figure out what I should do following the PhD. I enjoy research (a quick definition: identify problem, come up with solution, ask interesting questions, find ways to answer them, build system, experiment, contribute some new knowledge and publish). I also like teaching and supervising students. It would seem that a career in academia is the ideal thing to do (can work on non-trivial problems and contribute something of use to some or more people). However, a career in academia has two significant drawbacks. First, it can be difficult to gain access to real systems with real users which then display real problems. This creates the danger that you do work that seems important (to you and maybe to some of your colleagues), but is not really relevant to anything or anyone. Second, the pay is pretty sad. Apparently, you have to sacrifice this for the privilege of doing research. I enjoy programming, but don't just want to hack some web-based system for the rest of my life. That is, working in IT for a bank is not a future I see myself enjoying. I want to work on interesting problms (that's difficult to define clearly): things where you don't know how to start, that take some time to figure out and attack, that require a rigorous approach to demonstrate that the problem has been solved, and problems that need a solution in the real world. Give the experience of people on stackoverflow, what do you think suitable options are and why (or alternatively, what gaps in my thinking does the above reveal)? Is industrial research (aka IBM Research, Microsoft Research) the only alternative avenue to a career in academia? What other areas, companies, occupations, etc. could provide me with stimulating, inspiring work? Which regions, countries am I most likely to find such work? Please share your experience.

  • Catching an exception class within a template

    - by Todd Bauer
    I'm having a problem using the exception class Overflow() for a Stack template I'm creating. If I define the class regularly there is no problem. If I define the class as a template, I cannot make my call to catch() work properly. I have a feeling it's simply syntax, but I can't figure it out for the life of me. #include<iostream> #include<exception> using namespace std; template <class T> class Stack { private: T *stackArray; int size; int top; public: Stack(int size) { this->size = size; stackArray = new T[size]; top = 0; } ~Stack() { delete[] stackArray; } void push(T value) { if (isFull()) throw Overflow(); stackArray[top] = value; top++; } bool isFull() { if (top == size) return true; else return false; } class Overflow {}; }; int main() { try { Stack<double> Stack(5); Stack.push( 5.0); Stack.push(10.1); Stack.push(15.2); Stack.push(20.3); Stack.push(25.4); Stack.push(30.5); } catch (Stack::Overflow) { cout << "ERROR! The stack is full.\n"; } return 0; } The problem is in the catch (Stack::Overflow) statement. As I said, if the class is not a template, this works just fine. However, once I define it as a template, this ceases to work. I've tried all sorts of syntaxes, but I always get one of two sets of error messages from the compiler. If I use catch(Stack::Overflow): ch18pr01.cpp(89) : error C2955: 'Stack' : use of class template requires template argument list ch18pr01.cpp(13) : see declaration of 'Stack' ch18pr01.cpp(89) : error C2955: 'Stack' : use of class template requires template argument list ch18pr01.cpp(13) : see declaration of 'Stack' ch18pr01.cpp(89) : error C2316: 'Stack::Overflow' : cannot be caught as the destructor and/or copy constructor are inaccessible EDIT: I meant If I use catch(Stack<double>::Overflow) or any variety thereof: ch18pr01.cpp(89) : error C2061: syntax error : identifier 'Stack' ch18pr01.cpp(89) : error C2310: catch handlers must specify one type ch18pr01.cpp(95) : error C2317: 'try' block starting on line '75' has no catch handlers I simply can not figure this out. Does anyone have any idea?

  • "Correct" way to playback user movement with xlib?

    - by Dasuraga
    I'm trying to figure out a way to make demos for a program I've written with xlib, and I came across this, but, according to the author page: This extension is not intended to support general journaling and playback of user actions. Does anyone know of any functions in xlib that are intended to support playback of user actions? Does it even exist? Or could I just use this without any real problems?

  • How to bulk insert from CSV when some fields have new line character?

    - by z-boss
    I have a CSV dump from another DB that looks like this (id, name, notes): 1001,John Smith,15 Main Street 1002,Jane Smith,"2010 Rockliffe Dr. Pleasantville, IL USA" 1003,Bill Karr,2820 West Ave. The last field may contain carriage returns and commas, in which case it is surrounded by double quotes. I use this code to import CSV into my table: BULK INSERT CSVTest FROM 'c:\csvfile.csv' WITH ( FIELDTERMINATOR = ',', ROWTERMINATOR = '\n' ) SQL Server 2005 bulk insert cannot figure out that carriage returns inside quotes are not row terminators. How to overcome?

  • Porting getifaddrs to Win XP

    - by Goz
    Hi all, I'm trying to port a MacOSX app to windows and I've come up against a problem around getifaddrs. Basically windows does not support it. I'm trying to figure a way to re-implement it (for AF_INET and AF_INET6) but the "equivalent" functionality on windows appears to be nothing like the MacOSX support. Has someone done this sort of conversion before? If so is there a nice way I can get windows to report me interface info like MacOSX does?

  • How to show printer properties/preferences dialog?

    - by Patrick Klug
    I can't figure out how to properly show the printer preference dialog of a given printer so that the user can change the printer settings. Most of the examples that I can find online manage to show the dialog but any changes the user might make are lost which makes it useless. Example: http://www.codeproject.com/KB/system/PrinterPropertiesWindow.aspx (I tried to change the code as suggested by BartJoy but that didn't fix it) Does anyone know how to do this properly?

  • FullCalendar Events: Confused how to enable resizing.

    - by Josiah Kiehl
    I'm using the FullCalendar plugin, and am very pleased with it, however I can't figure out how to enable resizing. I looked at the source of the calendar on the main FullCalendar page, and my code is no different save that I get my events from a source rather than explicitly define them. What am I missing? $('#schedule').fullCalendar({ events: '/campaigns/scheduled', editable: true });
