  • If item not in the lst in scheme

    - by ms. sakura
    I'm working on context-free grammars, and I have a function that returns the (terminal values of grammar) for example: i have non-terminal function that results in (A B) , from calling say ((A cat) (B happy np) (A B sad)) so technically A and B are non terminals of the grammar. Now I want to be able to get the terminals (cat happy np sad) (define terminals (lambda (lsts) (cond ((null? lsts) lsts) ((not(member? (car(car lsts)) (n-terminals lsts))) (cons (car(car lsts)) (terminals (car (cdr lsts))))) (else (terminals (cdr lsts)))))) PS: functionality of n-terminals is described above. member? is a boolean function that returns true if an item is a member of the list, false otherwise. My function returns an empty lst. What am I missing here?

  • about buffer overflow

    - by Abed
    hello guys, I am new to the ethical hacking world, and one of the most important things is the stack overflow, anyway I coded a vulnerable C program which has a char name [400] statement, and when I try to run the program with 401A's it doesn't overflow, but the book which I am following says it must overflow and the logic sense says so, so what's wrong???

  • Computer science undergraduate project ideas

    - by Mehrdad Afshari
    Hopefully, I'm going to finish my undergraduate studies next semester and I'm thinking about the topic of my final project. And yes, I've read the questions with duplicate title. I'm asking this from a bit different viewpoint, so it's not an exact dupe. I've spent at least half of my life coding stuff in different languages and frameworks so I'm not looking at this project as a way to learn much about coding and preparing for real world apps or such. I've done lots of those already. But since I have to do it to complete my degree, I felt I should spend my time doing something useful instead of throwing the whole thing out. I'm planning to make it an open source project or a hosted Web app (depending on the type) if I can make a high quality thing out of it, so I decided to ask StackOverflow what could make a useful project. Situation I've plenty of freedom about the topic. They also require 30-40 pages of text describing the project. I have the following points in mind (the more satisfied, the better): Something useful for software development Something that benefits the community Having academic value is great Shouldn't take more than a month of development (I know I'm lazy). Shouldn't be related to advanced theoretical stuff (soft computing, fuzzy logic, neural networks, ...). I've been a business-oriented software developer. It should be software oriented. While I love hacking microcontrollers and other fun embedded electronic things, I'm not really good at soldering and things like that. I'm leaning toward a Web application (think StackOverflow, PasteBin, NerdDinner, things like those). Technology It's probably going to be done in .NET (C#, F#) and Windows platform. If I really like the project (cool low level hacking), I might actually slip to C/C++. But really, C# is what I'm efficient at. Ideas Programming language, parsing and compiler related stuff: Designing a domain specific programming language and compiler Templating language compiled to C# or IL Database tools and related code generation stuff Web related technologies: ASP.NET MVC View engine doing something cool (don't know what exactly...) Specific-purpose, small, fast ASP.NET-based Web framework Applications: Visual Studio plugin to integrate with Bazaar (it's too much work, I think). ASP.NET based, jQuery-powered issue tracker (and possibly, project lifecycle management as a whole - poor man's TFS) Others: Something related to GPGPU Looking forward for great ideas! Unfortunately, I can't help on a currently existing project. I need to start my own to prevent further problems (as it's an undergrad project, nevertheless).

  • Nested Row problem

    - by Patrick
    Hi, I'm using the 1kb css grid framework for a site, and although nested rows are apparently supported by the framework, when I try to drop in a nested row it doesn't work! Sorry not to explain it better - the site's here, may be easier to just look at the source: http://2605.co.uk/saf/build/ the grid: /grid.css the stylesheet: /style.css I'm a graphic designer hacking his way through a site he shouldn't be having to build but there's no budget to speak of! Cheers for any help, Patrick

  • Robust, Mature HTML Parser for PHP

    - by Alan Storm
    Are there any robust and mature HTML parsers available for PHP? A quick skimming of PEAR didn't turn anything up (lots of classes for generating HTML, not so much for consuming), and Google taught me a lot of people have started and then abandoned a variety of parser projects. Not interested in XML parsers (unless then can consume non-well formed HTML) or hacking it on my own with regular expressions. Clarification of Intent: I'm not interested in filtering of HTML content, I'm interesting in extracting information from HTML documents.

  • Rookie PHP question

    - by Thomas
    I am hacking together a theme for wordpress and I am using the following code to pull out data from a custom field with several values: <?php $mykey_values = get_post_custom_values('services'); foreach ( $mykey_values as $key => $value ) { echo "<span>$value, </span>"; } ?> I use a comma to seperate the results, but I don't want a comma after the last result. How do I get around this?

  • Getting Data From Webpages?

    - by fuzzygoat
    When looking to get data from a web page whats the recommended method if the page does not provide a structured data feed? Am I right in thinking that its just a case of doing an NSURLRequest and then hacking what you need out of the responseData(NSData*)? I am not too concerned about the implementation in Xcode, I am more curious about actually collecting the data, before I start coding a "hunt & peck" through a list of data. gary

  • iPhone App Licenses

    - by Hilde VanJoose
    Hi, After months of hacking, I am about to release my first iPhone app into the wild. Before I release I'm wondering if I should include some sort of licensing information in the help page of my app. Are all iPhone apps that are downloaded through the App Store covered under some sort of Apple license, or do I need to provide my own license information? If I do, are there any examples out there that I could use as a reference? Thanks very much!

    Hi, I have an activity that uses VideoView and MediaController. I have a .mp4 file. (1) When I put the file in res/raw folder, I can play the video using Uri.parse("android.resource://<package>/" + R.raw.id_video) (2) However, when I put the same file in the file-system, it plays properly. I use videoView.setVideoPath("/sdcard/myfile.mp4"); What can be the problem? -- Happy Hacking, Gaurav www.mastergaurav.com

  • How do I disable "eager" validation entirely using jquery validate ?

    - by Kevin J
    Is there a way to disable "eager" validation using the jquery.validate plugin? Either through an option in the script or as a hack? "Eager" validation kicks in once the form has been validated once - after that, invalid fields are validated onfocusout. I want to disable this behavior, and change my forms to only be validated when the submit button is pressed. I don't mind hacking through the validate script itself also, so if that's what the solution requires that's acceptable.

  • How are you using IronPython?

    - by Will Dean
    I'm keen to drink some modern dynamic language koolaid, so I've believed all the stuff on Michael Foord's blog and podcasts, I've bought his book (and read some of it), and I added an embedded IPy runtime to a large existing app a year or so ago (though that was for someone else and I didn't really use it myself). Now I need to do some fairly simple code generation stuff, where I'm going to call a few methods on a few .net objects (custom, C#-authored objects), create a few strings, write some files, etc. The experience of trying this leaves me feeling like the little boy who thinks he's the only one who can see that The Emperor has no clothes on. If you're using IronPython, I'd really appreciate knowing how you deal with the following aspects of it: Code editing - do you use the .NET framework without Intellisense? Refactoring - I know a load of 'refactoring' is about working around language-related busywork, so if Python is sufficiently lightweight then we won't need that, But things like renames seem to me to be essential to iteratively developing quality code regardless of language. Crippling startup time - One of the things which is supposed to be good about interpreted languages is the lack of compile time leading to fast interactive development. Unfortunately I can compile a C# application and launch it quicker than IPy can start up. Interactive hacking - the IPy console/repl is supposed to be good for this, but I haven't found a good way to take the code you've interactively arrived at and persist it into a file - cut and paste from the console is fairly miserable. And the console seems to hold references to .NET assemblies you've imported, so you have to quit it and restart it if you're working on the C# stuff as well. Hacking on C# in something like LinqPad seems a much faster and easier way to try things out (and has proper Intellisense). Do you use the console? Debugging - what's the story here? I know someone on the IPy team is working on a command-line hobby-project, but let's just say I'm not immediately attracted to a command line debugger. I don't really need a debugger from little Python scripts, but I would if I were to use IPy for scripting unit tests, for example. Unit testing - I can see that dynamic languages could be great for this, but is there any IDE test-runner integration (like for Resharper, etc). The Foord book has a chapter about this, which I'll admit I have not yet read properly, but it does seem to involve driving a console-mode test-runner from the command prompt, which feels to be an enormous step back from using an integrated test runner like TestDriven.net or Resharper. I really want to believe in this stuff, so I am still working on the assumption that I've missed something. I would really like to know how other people are dealing with IPy, particularly if they're doing it in a way which doesn't feel like we've just lost 15 years'-worth of tool development.

  • msysgit git-am can't apply it's own git format-patch sequence

    - by Andrian Nord
    I'm using msysgit git on windows to operate on central svn repository. I'm using git as I want to have it's awesome little local branches for everything and rebasing on each other. I also need to update from central repo often, so using separate svn/git is not an option. Problem is - git svn --help (man page) says that it is not a good idea to use git merge into master branch (which is set to track from svn's trunk) from local branches, as this will ruin the party and git svn dcommit would not work anymore. I know that it's not exactly true and you may use git merge if you are merging from branch which was properly rebased on master prior merge, but I'm trying to make it safer and actually use git format-patch and git am. We are using code review, so I'm making patches anyway. I also knew about git cherry-pick, but I want to just git am /reviewed/patches/dir/* without actually recalling what commits was corresponding to this patches (without reading patches, that is). So, what's wrong with git svn and git am? It's simple - git am for a few very hard points is doing CRLF into LF conversion for patches supplied (git-mailsplit is doing this, to be precise), if not rebasing. git format-patch is also producing proper (LF-ended) patches. As my repo is mostly CRLF (and it should remain so), patches are, obviously, failing due to wrong EOL. Converting diffs to CRLF and somehow hacking git am to prevent it from conversion is not working, too. It will fail if any file was removed or deleted - git apply will complain about expected /dev/null (but he got /dev/null^M). And if I'm applying it with git am --ignore-space-change --ignore-whitespace that it will commit LF endings straight to the index, which is also weird. I don't know if it will preserve over commiting into svn (via git svn dcommit) and checking it out and I don't want to try out. Of course, it's still possible to try hacking around patches to convert only actual diffs, but this is too much hacks for simple task. So, I wonder, is there really no established way to produce patches and apply them to the same repo on the same system? It just feels weird that msysgit can't apply it's own patches.

  • Is there a way to prevent UIImagePickerController change statusbar style?

    - by Eonil
    UIImagePickerController changes statusbar style to black/opaque. I want to keep status-bar style black/translucent. I'm finding a way to prevent status bar style changing. Or making it transited smoothly. Now, presenting UIImagePickerController changes status-bar style instantly, even -[presentModalViewController:picker animated:YES] specified. Any method, welcome, including hacking or private method. This is an app for AppStore, however I want to even try.

  • How do you protect your software from illegal distribution?

    - by petr k.
    I am curious about how do you protect your software against cracking, hacking etc. Do you employ some kind of serial number check? Hardware keys? Do you use any third-party solutions? How do you go about solving licensing issues? (e.g. managing floating licenses) EDIT: I'm not talking any open source, but strictly commercial software distribution...

    I'm making a program to improve your gaming skills, so its not a hacking program!! Now, i'm stuck on 1 thing, i need sort of a keylogger, that will logg what you do, For example, when you press space, it has to put Jumped in a Rich Text Box. When you left mouse click, it has to add Shots Fired to the Rich Text Box, and then , when right mousebutton is clicked, add Aiming Down Sights, but when its released it should also add something like Stopped Aiming Down Sights Can anyone help me on this?

  • Detecting a stale Mutex

    Is there any technique or tool available to detect this kind of a deadlock during runtime? picture this in a worker thread (one of several, normally 4-6) try WaitForSingleObject(myMutex); DoSTuffThatMightCauseAnException; Except ReleaseMutex(myMutex); end; or more generally is there a design-pattern to avoid these kind of bugs? I coded the above code in the little hous after a longer hacking run

  • coco2d tab view for multi player

    - by godzilla
    I am currently developing a card game for the iphone using cocas2d. I am currently in need of a tab view with each tab representing a player and his / her set of cards. Currently i have a single view representing just one player. It seems as though cocas2s is not really built do have multiple views, to do this and it would require some serious amount of hacking around with the code. What would be the most efficient way to accomplish this?

    I can already see that I'm not going to enjoy the experience, but I have to do some sql cleanup on this 1000 file asp classic web-app, and before I get to hacking away at it I'd like to be aware of any major gotchas to watch out for with asp classic/sql parameter preparing/asp whitespace altering. What are some good quick overview resources, and what should I watch out for?

  • Instead of buying VS 2010 what options will you use for .net development in the future?

    - by Eric Neunaber
    Given the recent release of VS 2010 I was shocked to see the pricing structure for the different versions of the product. I was lucky enough to receive free versions of VS 2005 and 2008 from attending various MS events. For the hacking I do at home I'm not sure I'm going to spend the money to purchase the IDE and wanted to see what others were using. Like SharpDevelop MonoDevelop Expess Editions
