  • Correct way to protect a private API key when versioning a python application on a public git repo

    - by systempuntoout
    I would like to open-source a python project on Github but it contains an API key that should not be distributed. I guess there's something better than removing the key each time a "push" is committed to the repo. Imagine a simplified foomodule.py : import urllib2 API_KEY = 'XXXXXXXXX' urllib2.urlopen("http://example.com/foo?id=123%s" % API_KEY ).read() What i'm thinking is: Move the API_KEY in a second key.py module importing it on foomodule.py; i would then add key.py on .gitignore file. Same as 1 but using ConfigParser Do you know a good programmatic way to handle this scenario?

  • Jquery Scrolling

    - by Rich - Pixel Vector
    I have implemented the following code from this page: http://tympanus.net/codrops/2010/06/02/smooth-vertical-or-horizontal-page-scrolling-with-jquery/ $(document).ready(function() { $('ul.navone li a, ul.navtwo li a,a.toplink, a.bodylink').bind('click',function(event){ var $anchor = $(this); $('html, body, header').stop().animate({ scrollTop: $($anchor.attr('href')).offset().top }, 1500,'easeInOutExpo'); event.preventDefault(); }); }); This all works correctly. However, in my layout I have a fixed header div (i.e. it stays in place when the user scrolls). Therefore I need to set an offset for the scrolling script of 117 pixels. How do I do this please?

  • How do I reload servlet classes without restarting my web application?

    - by Ramon
    I want to reload just my web layer classes without reloading my service layer classes (which take longer to initialize and change less frequently). There are no references from my service layer into the web layer and I can create a whole new instance of the web layer without problems. I can conceive of a solution involving complicated class-loader tricks to isolate the web layer in its own class-loader and I think this is probably the only way to do this so what I'm asking is, is there a library out there which does this? I know about JavaRebel - I don't need that much power and I'm really looking for a more lightweight free solution.

  • Why learn Perl, Python, Ruby if the company is using C++, C# or Java as the application language?

    - by szabgab
    I wonder why would a C++, C#, Java developer want to learn a dynamic language? Assuming the company won't switch its main development language from C++/C#/Java to a dynamic one what use is there for a dynamic language? What helper tasks can be done by the dynamic languages faster or better after only a few days of learning than with the static language that you have been using for several years? Update After seeing the first few responses it is clear that there two issues. My main interest would be something that is justifiable to the employer as an expense. That is, I am looking for justifications for the employer to finance the learning of a dynamic language. Aside from the obvious that the employee will have broader view, the employers are usually looking for some "real" benefit.

  • Writing jQuery functions that allow chaining.

    - by Rich Bradshaw
    I want to write some code that allows me to replace jQuery's animate function with one that does different things, but still allows me to call a secondary function on completion. At the moment, I'm writing lots of code like this; if (cssTransitions) { $("#content_box").css("height",0); window.setTimeout(function() { secondFunction(); }, 600); } else { $("#content_box").animate({ height:0 }, 600, function() { secondFunction(); }); } I'd much rather write a function that looks like this: function slideUpContent(object) { if (cssTransitions) { object.css("height",0); // Not sure how I get a callback here } else { $("#content_box").animate({ height:0 }, 600, function() { }); } } That I could use like this: slideUpContent("#content_box", function(){ secondFunction(); }); But I'm not sure how to get the functionality I need - namely a way to run another function once my one has completed. Can anyone help my rather addled brain?

  • Why do i get segfault at the end of the application after everything's beed done properly ?

    - by VaioIsBorn
    #include <string.h> #include <stdlib.h> #include <stdio.h> int main(void) { unsigned char *stole; unsigned char pass[] = "m4ak47"; printf("Vnesi password: \t"); scanf("%s", stole); if(strncmp(stole, pass, sizeof(pass)) != 0) { printf("wrong password!\n"); exit(0); } else printf("Password correct\n"); printf("some stuf here...\n\n"); return 0; } This program is working nice, but with one problem - if the password is correct then it DOES do the printing of 'some stuf here...' but it also shows me segmentation fault error at the end. Why ?

  • What would be a good starting point for development of a 3D application for representation of struct

    - by Lela Dax
    I was thinking QT on OpenGL. Multiplatform ability and being able to be closed (at no cost) at a later point would be important points. But I'm very interested in finding a way that is not only viable but also has the least amount of reinvention of the wheel. e.g. "Why not Ogre? A ready powerful 3D engine without reinventing that part". But I'm very uncertain in what is the optimal collection of tools for that job.

    - by senrulz

    - by Nader Rahimizad
    Hi Guys, Do you know what could cause this as a return for a Facebook Canvas app. It works for most users of our site but some users, it generates this and i cant figure out what would cause this. The userID is returned as 0 and the Token seems to be missing something. there is no other way for the users to reach the site other than visiting the Facebook App page... Please let me know what i can do to prevent this from happening UserID: 0 Token: 104743107829|b8bbc20eac6127d8a9a85451490a0663 Quesrty String:signed_request=W13Y8eiSHTyyqBnyJjll8WngPFeQqabhVBkJaHnXYb4.eyJhbGdvcml0aG0iOiJITUFDLVNIQTI1NiIsImlzc3VlZF9hdCI6MTI5NDU5NjIwMywidXNlciI6eyJsb2NhbGUiOiJpdF9JVCIsImNvdW50cnkiOiJpdCJ9fQ

  • Is it possible to talk to the iPhone simulator/device.

    - by Plumenator
    I need to automate the build/deploy process for my iphone applications from a script. I can use xcodebuild to build the project, then use Applescript to deploy and debug/run the application. Assuming the application will stop by itself after a while, I need to collect the generated logs for verification. But the problem is I have no way to know when the application ended from outside of the application itself. If the running time is fixed, I can again use Applescript to stop the application (Cmd+Shift+Enter). So there has to be a way to connect to the device/simulator and wait on the application somehow.

  • What things can I teach a group of children about programming in one day?

    - by Rich Bradshaw
    I'm running a day for 30 kids aged 11-18 about computer game programming. They have all opted to do it, but they have no experience at all of programming. My main aim is for them to learn a few things: programming is hard/challenging programming is something they can learn to do being a computer games programmer != playing games all day a little more insight into how games actually work I'd thought of splitting them into two groups, of younger/less experience and older/more experience, then doing slightly different things. I'd considered showing them Scratch, Game Maker, before showing them the basics of Python and getting them to write a simple text based game (perhaps something like, computer picks a random number, you have to guess it in as few guesses as possible, computer says higher/lower for each guess). Does anyone have any ideas of things to do/show them/ways to teach them?

  • How can I use multithreading in a Windows Forms application to update a progress bar?

    - by Steve Syfuhs
    There are two objects. The Windows Form with a button and a progress bar, and another object that handles an algorithm. In the algorithm object there is an event, and a property. The event is ProgressChanged, and the property is Progress (which is an int). In the calling window, the button starts off a set of steps in the algorithm object. As each step (or substeps) occurs, the ProgressChanged event fires, and in the window there is an event handler that essentially increments the progress bar relative to the Progress property. The problem I am running into is that because the algorithm has a possibility (and high liklihood) of running a relatively long time, I need to move it into it's own background thread and push the event back up to the window. My issue is that I'm not completely sure what I'm doing when it comes to multi-threading. I've looked at Control.Invoke and I'm a little lost. Can someone point me in the right direction?

  • Is pthread_spin_trylock safe inside of sigsegv handler of multithreaded application?

    - by TWMouton
    I am trying to implement a handler that on SIGSEGV will collect some information such as process-id, thread-id and a backtrace and write this information to a file/pipe/socket. The problem lies in that there is the (probably pretty high) possibility that if one thread experienced a SIGSEGV that the others will shortly follow. If two threads happen to make it to the bit of code where they're writing their report out at the same time then they'll interleave their writing (to the same file). I know that I should only be using async-signal-safe functions as detailed in signal(7) I also have seen at least two cases here and video linked in top answer here where others have used pthread_spin_trylock to get around this problem. Is this a safe way to prevent the above problem?

  • How can I layout a sidebar or pullquote?

    - by Rich
    I have 4 divs in a fixed width layout: a, b, c, and d, and they are ordered in the html like this: <div id="a"> </div> <div id="b"> </div> <div id="c"> </div> <div id="d"> </div> Using CSS, I want them to be laid out with divs a, b, and d in a vertical column, and div c to the right of and top-aligned with div b, like this: aaa aaa aaa bbbccc bbbccc bbbccc ddd ddd ddd I need this layout to work even though the divs contain unknown content, and so could be of varying length: aaa aaa aaa bbbccc bbbccc dddccc dddccc ddd or: aaa aaa aaa bbbccc bbb bbb ddd ddd ddd or even (if possible): aaa aaa bbbccc dddccc eeeccc eee I can't simply float div c to the right and then move it up, because, without using Javascript, I don't know the height of div b, and so don't know how much to move it up by. Is this possible in HTML and CSS, without reordering the divs?

  • How to design the application to conform to the n-tier architecture? (Winform sample in .net with li

    - by AlexRednic
    Rather a simple question. But the implications are vast. Over the last few weeks I've been reading a lot of material about n-tier architecture and it's implementation in the .NET world. The problem is I couldn't find a relevant sample for Winforms with Linq (linq is the way to go for BLL right?). How did you guys manage to grasp the n-tier concept? Books, articles, relevant samples etc.

  • How much does it cost to develop an iphone application?

    - by delooks
    How much can a developer charge for an iphone app like twitterrific. I want to know this because I need such an app with the same functionality for a new community website. I can do Ruby but have no experience with Objective C. So it would be interesting for me if I should start reading books about iPhone programming or outsource the work to a iPhone programmer.

  • Getting the current item number or index when using will_paginate in rails app

    - by Rich
    I have a rails app that stores movies watched, books read, etc. The index page for each type lists paged collections of all its items, using will_paginate to bring back 50 items per page. When I output the items I want to display a number to indicate what item in the total collection it is. The numbering should be reversed as the collection is displayed with most recent first. This might not relate to will_paginate but rather some other method of calculation. I will be using the same ordering in multiple types so it will need to be reusable. As an example, say I have 51 movies. The first item of the first page should display: Fight Club - Watched: 30th Dec 2010 Whilst the last item on the page should display: The Matrix - Watched: 3rd Jan 2010 The paged collection is available as an instance variable e.g. @movies, and @movies.count will display the number of items in the paged collection. So if we're on page 1, movies.count == 50, whilst on page 2 @movies.count == 1. Using Movie.count would give 51. If the page number and page size can be accessed the number could be calculated so how can they be returned? Though I'm hopeful there is something that already exists to handle this calculation!
