• [SCORM 2004] the cmi.total_time parameter does not return anything.

  - by Nephila

  I am programming a SCORM 2004 product. I can update the session_time, it works. I can set the status (passed, failed, etc...) I also can get the cmi.location time. No problems! But I don't succeed atingt get the total time (cmi.total_time). I have tested on 2 LMS: On Ganesha the API.GetValue('cmi.total_time') is an empty string. On Moodle the API.GetValue('cmi.total_time') is just a "P". I do have the correct logs with correct session times. EDIT. I also try on cloud.scorm.com and cmi.total_time returns each time PT0H0M0S.

• Unzip a folder which is programatically downloaded in Silverlight

  - by subbu

  Hi all, My requirement is this. I am programmatically downloading a folder from a remote server in zipped format using WebClient. This part is done. My folder will have only DLLs and EXEs. Can any one suggest an unzipping algorithim or libraries which can be used for unzipping? http://www.sharpgis.net/post/2009/04/21/REALLY-small-unzip-utility-for-Silverlight.aspx I tried out the method suggested in the above link. But my DLLs and EXEs are getting corrupted. Can any one help me out in this? My programming environment is VS2010 and Silverlight 4.0. Application is OOB and has Elevated Priv

• What's your favorite implementation of producing the fibonacci sequence?

  - by Terry Donaghe

  Best, most creative, most clever, fastest, smallest, written in weirdest language, etc etc. For those not familiar with this staple of programming exam question / interview question, check this out: Fibonacci Sequence at Wikipedia The question would be, write a simple program which will spit out the first n digits of the Fibonacci sequence. So, if n == 12, we produce: 0 1 1 2 3 5 8 13 21 34 55 89 144 Your implementation becomes more interesting when you set n to larger values. How long does it take your implementation to return a 25 digit sequence? How about 100?

• MD5 hash differences between Python and other file hashers

  - by Sam

  I have been doing a bit of programming in Python (still a n00b at it) and came across something odd. I made a small program to find the MD5 hash of a filename passed to it on the command line. I used a function I found here on SO. When I ran it against a file, I got a hash "58a...113". But when I ran Microsoft's FCIV or the md5sum.py in \Python26\Tools\Scripts\, I get a different hash, "591...ae6". The actual hashing part of the md5sum.py in Scripts is m = md5.new() while 1: data = fp.read(bufsize) if not data: break m.update(data) out.write('%s %s\n' % (m.hexdigest(), filename)) This looks functionally identical to the code in the function given in the other answer... What am I missing? (This is my first time posting to stackoverflow, please let me know if I am doing it wrong.)

• Combine two views into one view

  - by Kevin

  I have two views that I would like to combine into one. The first view shows all items of X where company ID = Y. This is to give preferential sort to the client first, and then everyone else. So I created a second view, all items of X, where company ID != Y. I created it as an Attachment to attach to the first view, but I don't think I got the intended result. How can I combine these views so the first view results are listed first, and then the second view is too, using the same pager, filters, and arguments? Is there any way of achieving this without programming it?

• How does one search/poll all modal info in a frame automatically?

  - by user310631

  As you'll no-doubt be able to tell momentarily, I have little knowledge of the programming world. That being said, here goes.... In this scenario, there's a Java-based game that has a map of the game world oriented in an X, Y coordinate tile system. Some of the grid tiles are player cities, some are non-player locations. The game runs inside a frame in the browser, the X, Y coordinate map feature is one optional view, and the entire map is not available to view at any one time. Each grid tile has an "Onclick" event and an "Onmouseover" event. The mouseover event is a tooltip, the click event is something called a "modal" that has information specific to that tile. What I'd like to find out is: How can I poll all the grid tiles' "modal" information using some kind of script or other auto-running polling feature?

• Using a different array for vertices and normals in glDrawElements (OpenGL/VBOs)

  - by Tuxer

  I'm currently programming a .obj loader in OpenGL. I store the vertex data in a VBO, then bind it using Vertex Attribs. Same for normals. Thing is, the normal data and vertex data aren't stored in the same order. The indices I give to glDrawElements to render the mesh are used, I suppose, by OpenGL to get vertices in the vertex VBO and to get normals in the normals VBO. Is there an opengl way, besides using glBegin/glVertex/glNormal/glEnd to tell glDrawElements to use an index for vertices and an other index for normals? Thanks

• Using a proxy for NSURLConnection

  - by SideSwipe

  Is there any way to get the content of a webfile (namely a .html Document) using a proxy, which is not defined in the system settings? I know that NSURLConnection is the right way to download a web file into a variable and not into a file (for which we should use NSURLDownload), but I don't find a way to use a proxy for it. Are there some unofficial APIs, Libraries or Classes or such I could use for what I want to do? I'm not that pro in Mac Programming, so I'm searching for something more or less simple. SideSwipe

• Python, implementing proxy support for a socket based application (not urllib2)

  - by Terry Felkrow

  Hey guys, I am little stumped: I have a simple messenger client program (pure python, sockets), and I wanted to add proxy support (http/s, socks), however I am a little confused on how to go about it. I am assuming that the connection on the socket level will be done to the proxy server, at which point the headers should contain a CONNECT + destination IP (of the chat server) and authentication, (if proxy requires so), however the rest is a little beyond me. How is the subsequent connection handled, specifically the reading/writing, etc... Are there any guides on proxy support implementation for socket based (tcp) programming in Python? Thank you

• How can I maximally partition a set?

  - by Gregory Higley

  I'm trying to solve one of the Project Euler problems. As a consequence, I need an algorithm that will help me find all possible partitions of a set, in any order. For instance, given the set 2 3 3 5: 2 | 3 3 5 2 | 3 | 3 5 2 | 3 3 | 5 2 | 3 | 3 | 5 2 5 | 3 3 and so on. Pretty much every possible combination of the members of the set. I've searched the net of course, but haven't found much that's directly useful to me, since I speak programmer-ese not advanced-math-ese. Can anyone help me out with this? I can read pretty much any programming language, from BASIC to Haskell, so post in whatever language you wish.

• Creating a unique id for a Core Data program on the iPhone

  - by Big Twisty

  I am fairly new at programming in Objective-C, having been a windows programmer since I was a kid. I am falling in LOVE with it. I am, however, having a bit of trouble figuring out this Core Data stuff. How do I create a new entry with a unique ID? In SQL I would just declare one field as an autoincrement field. I'm not seeing anything like that here, but I could just be missing something. I just want an auto incrementing NSInteger field, so when I manually add items to the database, I will have some form of reference to them.

• Confusing Perl code

  - by titaniumdecoy

  I don't understand the last line of this function from Programming Perl 3e. Here's how you might write a function that does a kind of set intersection by returning a list of keys occurring in all the hashes passed to it: @common = inter( \%foo, \%bar, \%joe ); sub inter { my %seen; for my $href (@_) { while (my $k = each %$href) { $seen{$k}++; } } return grep { $seen{$_} == @_ } keys %seen; } I understand that %seen is a hash which maps each key to the number of times it was encountered in any of the hashes provided to the function.

• Cilk or Cilk++ or OpenMP

  - by Aman Deep Gautam

  I'm creating a multi-threaded application in Linux. here is the scenario: Suppose I am having x instance of a class BloomFilter and I have some y GB of data(greater than memory available). I need to test membership for this y GB of data in each of the bloom filter instance. It is pretty much clear that parallel programming will help to speed up the task moreover since I am only reading the data so it can be shared across all processes or threads. Now I am confused about which one to use Cilk, Cilk++ or OpenMP(which one is better). Also I am confused about which one to go for Multithreading or Multiprocessing

• Designing a peer to peer network

  - by Varun

  I am designing a simple peer to peer network. The basic architecture will be as follows: A central server- that keeps track of all the peers. The job of this server is to keep track of all the peers that join the network. Every peer could do things: a. Download a file from it's peer b. Push a file (send a file) to it's peer. Could anybody please tell me what would be the best design for such a system? What would be the problems that i might run into and so on. I am planning to use Java as the programming language to implement. Would it be a good choice? Also, is it necessary that i would need a Linux box to develop the system? or is it fine if i use a Windows machine? Your help will be much appreciated! Thanks!

• What is the difference between remote procedure call and web service

  - by xiao

  Is there any clear definition about RPC and Web Service? A quick wikipedia search shows: RPC: Remote procedure call (RPC) is an Inter-process communication technology that allows a computer program to cause a subroutine or procedure to execute in another address space (commonly on another computer on a shared network) without the programmer explicitly coding the details for this remote interaction. Web Service: Web services are typically application programming interfaces (API) or web APIs that are accessed via Hypertext Transfer Protocol and executed on a remote system hosting the requested services. Web services tend to fall into one of two camps: Big Web Services[1] and RESTful Web Services. I am not quite clear what the real difference between the two things. It seems that one thing could belongs to RPC and is kind of web service at the same time. Is Web Service a higher level representation of RPC?

• How to write a technical blog?

  - by Gutzofter

  I have a blog that I would like to increase traffic on. I've read lots of technical blogs, but it's a lot different writing a blog versus reading a blog. There seems to be several ways to write a post. General article: I like this tool. This is how I do it. Specific technical issue: Programming solutions. I do get some traffic, but they don't leave any comments. Should I use HN and Reddit. What are some of the other places I can promote my blog? How to respond to negative comments (trolls)? Another thing is you might want to have some link-thrus. comment on other peoples blog posts. BTW my blog is: (defun ugly-lisp-code () ()) New Blog ugly web development

• Do we really need a safe release macro?

  - by Ian1971

  Quite a lot of people seem to use a macro such as #define SAFE_RELEASE(X) [X release]; X = nil; (myself included). I've been reassessing why I am using it and wanted to canvas some opinion. The purpose (I think) for using this macro is so that if you were to accidentally use your object after releasing it then you won't get a bad access exception because objective-c will quite happily ignore it when the object is nil. It strikes me that this has the potential to mask some obscure bugs. Maybe it would actually be preferable for the program to crash when you try to use X again. That way during testing you can find the issue and improve the code. Does this macro encourage lazy programming? Thoughts?

• In Visual Studio 2008, how can I make control+click do a "Go To Definition"?

  - by Blorgbeard

  I know this is not strictly about programming, but it's pretty close. Anyway, in Delphi, you can hold control and click on a method to jump to its definition. In VS2008, you have to right-click and select "Go To Definition". I use this function quite often, so I'd really like to get VS to behave like delphi in this regard - its so much quicker to ctrl+click. I don't think there's a way to get this working in base VS2008 - am I wrong? Or maybe there's a plugin I could use? Edit: Click then F12 does work - but isn't really a good solution for me.. It's still way slower than ctrl+click. I might try AutoHotkey, since I'm already running it for something else. Edit: AutoHotkey worked for me. Here's my script (I'm a complete n00b, so it's probably suboptimal): SetTitleMatchMode RegEx #IfWinActive, .* - Microsoft Visual Studio ^LButton::Send {click}{f12}

  Hi I hope I can get all the help i can get here. I am new to mobile phone programming. I find networking very interesting and I have this question: Does Mobile phone like WinMo or other phone have Server:Port scheme and what are the ports ? To show what I mean, I use PC to demonstarte, there are many ports ( restricted and established ). The below is the Server : Port scheme Server : port example WebServer 80 So, to use a TCPListener on PC , I can use any port as long as there are not restricted and establsihed) to listen incoming TcpClient . 2) How do I use a TCPListener and Which portNo I need to use to listen incoming TcpClient from the other end in Net Compact Framework?

• Object reference not set to an instance of an object - how to find the offending object name in the

  - by Jason

  This is the bane of my programming existence. After deploying an application, when this error crops up, no amount of debug dump tells you WHAT object was not instantiated. I have the call stack, that's great, it tells me roughly where the object is, but is there any way to get .NET to tell me the actual name of the object? If you catch them while debugging, of course the program breaks right on the offending creature, but if it happens after the program is in the wild, good luck. There has to be a way. I've explored the exceptions returned in these instances and there is just nothing helpful.

• help in security assignment

  - by scatman

  i have to write a program that sniffs network packets (part1-the simple part). and i have to update the program (part2) so that it will be able to terminate connections. the specific requirements are: construct raw packets by specifying data link layer and network layer information including appropriate source and destination MAC and IP addresses. These packets are intended to terminate the connection. To do so, you should used SOCK_RAW as the socket type to be able to set the header information by yourself. can anybody give me some ideas on the second part? should i hijack the session,apply a dos attack on one of the users?? all i need is some tips of how to terminate the connection. i am using c programming language. and this is a course assignment for the security course.
