  • Resolving "require"s when executing IronRuby from C#

    - by James Sulak
    I'm attempting to run an IronRuby script from C#: var runtime = IronRuby.Ruby.CreateRuntime(); runtime.ExecuteFile("ruby/foo.rb"); foo.rb starts with a "require:" #!/usr/bin/env ruby require 'bar' When I try this, I get an exception stating "no such file to load -- bar." The file "bar.rb" and the directory "bar" are both present in the "ruby" directory. So, how do I execute a ruby script that requires other ruby files? I'm targeting .Net 3.5.

  • Characters count only start counting on the 2nd character??

    - by Hwang
    I have a function that calculates how many characters remaining the user can type, but I don't know why it only starts counting from the 2nd characters. Means at the end I will able to type an extra character from the maximum amount I set. wInput.maxChars=30 wInput.addEventListener(KeyboardEvent.KEY_DOWN, calculate); private function calculate(event:Event=null):void { NameRC=wInput.maxChars-wInput.length; remainingA.text=NameRC; }

  • how to start with a voip/public announcement project?

    - by Metiu
    The main requirements are: open source solution on Linux support P2P VoIP calls support presence support multicast VoIP announcements (and maybe some way of setting up such a "conference") preferably serverless (maybe the network can get split and I'd need to keep the functionality for all clients that still see each other) I tried looking at telepathy, in particular telepathy-salut, but it seems to be quite a new technology, so it lacks clear/good documentation and/or working examples. I'm also evaluating SIP (e.g. SofiaSIP), but it's working only if connected to a server.

  • Curious enigma of a network cable / connection / quality

    - by Foo Bar
    So, the situation is like this: I'm renting an apartment in a large house and I'm sharing internet with the landlord who lives downstairs. The internet is (in my best guess) optical 20/20Mbit. I don't know how it's all wired in his flat (haven't been there / seen it). Anyway, in my flat comes a cable which seems to be connected directly to the optic to ethernet router (and the password is the default one, so I have access, he he). There was a switch connected to that and to wires that go around the flat, and the wiring is terrible. It's even mixing phone and ethernet, and from what I see some cables are even interconnected!? Anyways, this cable that comes to my flat is very short. I can barely connect my computer on it, but if I do, I seem to get decent speed / performance. Not great, but decent. If, however, I connect switch to it (tried 2 different switches and a wifi switch) it's all blinking but I can't even connect to 192.168.1.1 (the router). DHCP fails, ping is losing 80-100% of replies. So I connected this cable directly to the other cable which goes to my work room, with a connector that has two female jacks and no electronics. Now when I connect my computer in my room, again, the performance is decent. When I connect WRT54GL (with tomato, DHCP disabled) to it and I plug a cable in this WRT and to my computer... the performance is gone. Download seems okay on Speedtest, but upload is .2Mbps and it's connecting forever. So what kind cable troll am I having here? Any ideas?

  • Why is piping dd through gzip so much faster than a direct copy?

    - by Foo Bar
    I wanted to backup a path from a computer in my network to another computer in the same network over a 100MBit/s line. For this I did dd if=/local/path of=/remote/path/in/local/network/backup.img which gave me a very low network transfer speed of something about 50 to 100 kB/s, which would have taken forever. So I stopped it and decided to try gzipping it on the fly to make it much smaller so that the amount to transfer is less. So I did dd if=/local/folder | gzip > /remote/path/in/local/network/backup.img.gz But now I get something like 1 MB/s network transfer speed, so a factor of 10 to 20 faster. After noticing this, I tested this on several paths and files and it was always the same. Why does piping dd through gzip also increase the transfer rates by a large factor instead of only reducing the bytelength of the stream by a large factor? I'd expected even a small decrease in transfer rates instead, due to the higher CPU consumption while compressing, but now I get a double plus. Not that I'm not happy, but just wondering. ;)

  • Ruby Module Inclusion in Methods

    - by Federico Builes
    In class Foo I'd like to include method Bar under certain conditions: module Bar def some_method "orly" end end class Foo def initialize(some_condition) if !some_condition "bar" else class << self; include Bar; end end end end Is there any cleaner (and clearer) way to achieve the include in the method without having to do it inside the singleton class?

  • I start programming in j2me, how to get the maximum compatibility with every cellphone?

    - by netadictos
    Hi, I am a newbie to J2me. I am programming a Java program to recognise QRs. The specifications of the projects include the compatibility with most of cellphones. For example, Nokia with Symbian, Iphone or HTC with windows mobile. I have started downloading, JDK, WTK, eclipse and MTJ. Any other advice would be of help. To do this, i will need to provide a different distro for every commercial mark? or OS?

  • Learning PHP - start out using a framework or no?

    - by Kevin Torrent
    I've noticed a lot of jobs in my area for PHP. I've never used PHP before, and figure if I can get more opportunities if I pick it up then it might be a good idea. The problem is that PHP without any framework is ugly and 99% of the time really bad code. All the tutorials and books I've seen are really lousy - it never shows any kind of good programming practice but always the quick and dirty kind of way of doing things. I'm afraid that trying to learn PHP this way will just imprint these bad practices in my head and make me waste time later trying to unlearn them. I've used C# in the past so I'm familiar with OOP and software design patterns and similar. Should I be trying to learn PHP by using one of the better known frameworks for it? I've looked at CakePHP, Symfony and the Zend Framework so far; Zend seems to be the most flexible without being too constraining like Cake and Symfony (although Symfony seemed less constraining than CakePHP which is trying too hard to be Ruby on Rails), but many tutorials for Zend I've seen assume you already know PHP and want to learn to use the framework. What would be my best opportunity for learning PHP, but learning GOOD PHP that uses real software engineering techniques instead of spaghetti code? It seems all the PHP books and resources either assume you are just using raw PHP and therefore showcase bade practices, or that you already know PHP and therefore don't even touch on parts of the language.

  • Learning SQL & Microsoft Data Services stack - Where to start?

    - by Jim
    I'm trying to learn the Microsoft data / service stack. I want to build a database in SQL Azure and expose it to a c# client application. I've never worked with any SQL database technology. Looking online, everything just seems so confusing -- too many technologies, hard to tell what's new vs what's old. What's the latest technologies to look at, and what (books?) should I be reading?

  • Storing a NTFS Security Descriptor in C

    - by Doori Bar
    My goal is to store a NTFS Security Descriptor in its identical native state. The purpose is to restore it on-demand. I managed to write the code for that purpose, I was wondering if anybody mind to validate a sample of it? (The for loop represents the way I store the native descriptor) This sample only contains the flag for "OWNER", but my intention is to apply the same method for all of the security descriptor flags. I'm just a beginner, would appreciate the heads up. Thanks, Doori Bar #define _WIN32_WINNT 0x0501 #define WINVER 0x0501 #include <stdio.h> #include <windows.h> #include "accctrl.h" #include "aclapi.h" #include "sddl.h" int main (void) { DWORD lasterror; PSECURITY_DESCRIPTOR PSecurityD1, PSecurityD2; HANDLE hFile; PSID owner; LPTSTR ownerstr; BOOL ownerdefault; int ret = 0; unsigned int i; hFile = CreateFile("c:\\boot.ini", GENERIC_READ | ACCESS_SYSTEM_SECURITY, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, NULL); if (hFile == INVALID_HANDLE_VALUE) { fprintf(stderr,"CreateFile() failed. Error: INVALID_HANDLE_VALUE\n"); return 1; } lasterror = GetSecurityInfo(hFile, SE_FILE_OBJECT, OWNER_SECURITY_INFORMATION , &owner, NULL, NULL, NULL, &PSecurityD1); if (lasterror != ERROR_SUCCESS) { fprintf(stderr,"GetSecurityInfo() failed. Error: %lu;\n", lasterror); ret = 1; goto ret1; } ConvertSidToStringSid(owner,&ownerstr); printf("ownerstr of PSecurityD1: %s\n", ownerstr); /* The for loop represents the way I store the native descriptor */ PSecurityD2 = malloc( GetSecurityDescriptorLength(PSecurityD1) * sizeof(unsigned char) ); for (i=0; i < GetSecurityDescriptorLength(PSecurityD1); i++) ((unsigned char *) PSecurityD2)[i] = ((unsigned char *) PSecurityD1)[i]; if (IsValidSecurityDescriptor(PSecurityD2) == 0) { fprintf(stderr,"IsValidSecurityDescriptor(PSecurityD2) failed.\n"); ret = 2; goto ret2; } if (GetSecurityDescriptorOwner(PSecurityD2,&owner,&ownerdefault) == 0) { fprintf(stderr,"GetSecurityDescriptorOwner() failed."); ret = 2; goto ret2; } ConvertSidToStringSid(owner,&ownerstr); printf("ownerstr of PSecurityD2: %s\n", ownerstr); ret2: free(owner); free(ownerstr); free(PSecurityD1); free(PSecurityD2); ret1: CloseHandle(hFile); return ret; }

  • Are incremental Macro definition possible?

    - by Davorak
    I often find the following type of incremental definition useful: (define (foo) (display "bar")) (foo) ;prints bar (define foo (let ((bar foo)) (lambda () (display "foo") (bar)))) (foo) ;prints foobar How do I preform this type of incremental definition with macros? I could not get let-syntax to provide the same functionality. Currently I use plt scheme, but would like to see answers in different lisp implementations as well.

  • Should I start to use CSS 3 & HTML 5?

    - by LeonixSolutions
    I fear this may sound subjective, sorry. I am wondering how "safe" it is to use CSS3 & HTML5 in a commercial app. I really want the power that they give, but am obviously wary that they are not completely standardized. If it helps any I can probably enforce the use of Chrome as the browser; I can likely offer FireFox as an alternative. I personally do not want to let the user choose their own browser and can probably enforce my choice in a corporate environment which is already heavily biased towards Google. I suppose that if I can enforce a Chrome only policy & carefully test before release then my only worry is that some "behaviour" may change in future. Would you risk it, or would play safe (or go with an alternative, such as a Java app, forgetting the browser)?

  • Visual studio 2010 colourizers, intellisense and the rest. Where to start!!

    - by Owen
    Ok, before I begin I realize that there is a lot of documentation on this subject but I have thus far failed to get even basic colourization working for VS2010. My goal is to simply get to a point where I can open a document and everything is coloured red, from here I can implement the relevant parsing logic. Here's what I have tried/found: 1) Downloaded all the relevent SDK's and such- Found the ook sample (http://code.msdn.microsoft.com/ookLanguage) - didn't build, didn't work. 2) Knowing almost nothing about MEF read through "Implementing a Language Service By Using the Managed Package Framework" - http://msdn.microsoft.com/en-us/library/bb166533(v=VS.100).aspx This was pretty much a copy and paste of all the basic stuff here, and also updating some references which were out of date with the sample see: http://social.msdn.microsoft.com/Forums/en-US/vsx/thread/a310fe67-afd2-4592-b295-3fc86fec7996 Now, I have got to a point where when running the package MEF appears to have hooked up correctly (I know this because with the debugger open I can see that the packages initialize and FDoIdle methods are being hit). When I open a file of the extension I have registered with the ProvideLanguageExtensionAttribute everything dies as if in an endless loop, yet no debug symbols hit (though they are loaded). Looking at the ook sample and the MEF examples they seem to be totally different approaches to the same problem. In the ook sample there are notions of Clasifications and Completion controllers which aren't mentioned in the MEF example. Also, they don't seem to create a Package or Language service, so I have no idea how it should work? With the MEF example, my assumption is that I need to hook into the "IScanner.ScanTokenAndProvideInfoAboutIt" to provide syntax highlighting? Which would be fine if I could ever hit this method. So my first question I guess is which approach should I be taking here? Or do they both somehow tie together? My second questions is, where can I find a basic fully working project that implements bog standard basic syntax highlighting and intellisense or VS2010? Thirdly, in the MEF example when I created a Package there were a bunch of test projects created for me. I appears that the integration tests launch the VS2010 test rig somehow, but the test fails. It would be good to write my service with tests but I have no idea what/how I can test each interaction so any references to testing Language services would be helpful. Finally, please throw any resource/book links my way that I may find useful. Cheers, Chris. N.B. Sorry I realize this is part question part rant, but I have never been so confused.

  • matplotlib - changing rect colours on the fly

    - by Nick
    I am playing with matplotlib - I have a bar chart, and I want to highlight the bar which user clicks. I have a callback that goes through a rect collection (the one I got from self.axis.bar(...)) and finds out which one was clicked (looking at the coordinates). At this point I want to call something to change the colour of the current bar. Is it possible? How do I do that?

  • Should I dive into ASP.NET MVC or start with ASP.NET Webforms?

    - by Sahat
    I plan to pick up Silverlight in the future. Possibility of going into Microsoft WPF. Currently learning Objective-C 2.0 w/ Cocoa. I already know Pros and Cons of ASP.NET MVC vs ASP.NET Webforms. What I want to know is what would be more "efficient" for me to learn given the circumstances above? By efficient I mean learning one design pattern once and then re-using it. Objective-C I believe uses MVC approach? What about Silverlight? WPF? So what do you think? Also as a side question is it true that ASP.NET Webforms is often used by freelancers/small companies and ASP.NET MVC in large enterprises?

  • Django admin: how do I add an unrelated model field to a model change/add page?

    - by NP
    I have the following models: class Foo(models.Model): field1 = models.IntegerField() ... class Bar(models.Model): field1 = models.IntegerField() ... class Foo_bar(models.Model): foo = models.ForeignKey(Foo) bar = models.ForeignKey(Bar) ... In the admin, I want it so that in the Foo change/add page, you can specify a Bar object, and on save I want to create a Foo_bar object to represent the relationship. How can I do this through customizing the Admin site/ModelAdmins? Thanks.
