  • tools for testing vim plugins

    - by intuited
    I'm looking for some tools for testing vim scripts. Either vim scripts that do unit/functional testing, or classes for some other library (eg Python's unittest module) that make it convenient to run vim with parameters that cause it to do some tests on its environment, and determine from the output whether or not a given test passed. I'm aware of a couple of vim scripts that do unit testing, but they're sort of vaguely documented and may or may not actually be useful: vim-unit: purports "To provide vim scripts with a simple unit testing framework and tools" first and only version (v0.1) was released in 2004 documentation doesn't mention whether or not it works reliably, other than to state that it is "fare [sic] from finished". unit-test.vim: This one also seems pretty experimental, and may not be particularly reliable. May have been abandoned or back-shelved: last commit was in 2009-11 ( 6 months ago) No tagged revisions have been created (ie no releases) So information from people who are using one of those two existent modules, and/or links to other, more clearly usable, options, are very welcome.

  • Does Python work in larger teams?

    - by Kugel
    I read this post last night and it got me thinking. I like python and "batteries", pypi and such. But I've only done python solo. Never tried it in a team. Are the points that Ted mentions valid? If they are how do teams cope with them? Does Python work in teams or even large teams? Or it kills productivity? I personally see the problems he mentions when I come back to my old code. Even when working with other modules sometimes I need to peek inside. I would like to hear people with experience on this.

  • MVC - Loading DLL programmactically

    - by mikechats
    I'm trying to implement a plugable architecture in asp.net MVC. I have based my modules on the following article - http://www.wynia.org/wordpress/2008/12/aspnet-mvc-plugins. I have a DLL that contains a simple controller, and a view. The view is an embedded resource within the DLL. The problem I'm having is, if I drop the DLL in the bin directory of my MVC application manually, then everything works perfectly i.e. the assembly loads correctly. But when I copy the DLL from a file upload input box (via a web form) into the bin directoy, I get an error (The module was expected to contain an assembly manifest.) when trying to load the assembly. I use the same DLL, what could the problem be?

  • WPF Show wait cursor before application fully loads

    - by e28Makaveli
    I want to show the wait cursor before my WPF application, composed using CAL, fully loads. In the constructor of the main window, I have the following code: public MainWindow([Dependency] IUnityContainer container) { InitializeComponent(); Cursor = System.Windows.Input.Cursors.Wait; Mouse.OverrideCursor = System.Windows.Input.Cursors.Wait; ForceCursor = true; //this.Cursor = System.Windows.Input.Cursors.AppStarting; // event subscriptions PresenterBase.EventAggregate.GetEvent<ModulesLoadedEvent>().Subscribe(OnModulesLoaded); } After all modules have been loaded, the following handler is invoked: private void OnModulesLoaded(EventArgs e) { allModulesLoaded = true; Mouse.OverrideCursor = null; Cursor = System.Windows.Input.Cursors.Arrow; } Problem is, I do not see this wait cursor. What I am missing here? FWIW, I got a hint from this post http://stackoverflow.com/questions/2078766/showing-the-wait-cursor TIA.

  • Can someone please explain to me the basic function of Intents in the Android OS?

    - by K-RAN
    I'm new to programming applications for the Android OS. As far as general architecture of the OS goes, I understand that processes are implemented as Linux processes and that each one is sandboxed. However, I'm utterly confused on the IPCs and syscalls (if any) used. I know that the IBinder is a form of this; parcels are sent back and forth between processes and Bundles are array forms of parcels (?). But even that is still unfamiliar to me. Same with Intents. All in all, I don't understand what kinds of IPCs are implemented and how. Could someone briefly explain to me the specific methods used by user level applications in Android OS to communicate with each other and the OS? I've done kernel programming and played with various IPCs in Linux (Ubuntu and Debian) so it would help immensely if this was all explained in relation to what I'm familiar with... Thanks in advance!

  • Software Protection: Shuffeling my application?

    - by Martijn Courteaux
    Hi, I want to continue on my previous question: http://stackoverflow.com/questions/3007168/torrents-can-i-protect-my-software-by-sending-wrong-bytes Developer Art suggested to add a unique key to the application, to identifier the cracker. But JAB said that crackers can search where my unique key is located by checking for binary differences, if the cracker has multiple copies of my software. Then crackers change that key to make them self anonymous. That is true. Now comes the question: If I want to add a unique key, are there tools to shuffle (a kind of obfuscation) the program modules? So, that a binary compare would say that the two files are completely different. So they can't locate the identifier key. I'm pretty sure it is possible (maybe by replacing assembler blocks and make some jumps). I think it would be enough to make 30 to 40 shuffles of my software. Thanks

  • When compiling programs to run inside a VM, what should march and mtune be set to?

    - by Russ
    With VMs being slave to whatever the host machine is providing, what compiler flags should be provided to gcc? I would normally think that -march=native would be what you would use when compiling for a dedicated box, but the fine detail that -march=native is going to as indicated in this article makes me extremely wary of using it. So... what to set -march and -mtune to inside a VM? For a specific example... My specific case right now is compiling python (and more) in a linux guest inside a KVM-based "cloud" host that I have no real control over the host hardware (aside from 'simple' stuff like CPU GHz m CPU count, and available RAM). Currently, cpuinfo tells me I've got an "AMD Opteron(tm) Processor 6176" but I honestly don't know (yet) if that is reliable and whether the guest can get moved around to different architectures on me to meet the host's infrastructure shuffling needs (sounds hairy/unlikely). All I can really guarantee is my OS, which is a 64-bit linux kernel where uname -m yields x86_64.

  • Using C# assemblies from VB6 code. Some issues.

    - by AngryHacker
    I have a C# assembly, which is regasmed, but is not in the GAC. In my VB6 code, I added a reference to the generated type library (the .tlb file). Then I instantiate the C# lib in my VB6 code. If I run it from the VB6 IDE, it does not work. The Set in the code below: Dim obj as MyCSharpNamespace.MyCSharpObject Set obj = New MyCSharpNamespace.MyCSharpObject causes this error: Automation error The system cannot find the file specified However, if I compile the VB6 project to an EXE and run it, it runs perfectly fine. I should add that all the VB6 project files (e.g. forms, modules, etc...) are in the same folder as the C# DLL and TLB. So why can't I run it from the IDE environment?

  • How to make external Mathematica functions interruptible?

    - by Szabolcs
    I had an earlier question about integrating Mathematica with functions written in C++. This is a follow-up question: If the computation takes too long I'd like to be able to abort it using Evaluation Abort Evaluation. Which of the technologies suggested in the answers make it possible to have an interruptible C-based extension function? How can "interruptibility" be implemented on the C side? I need to make my function interruptible in a way which will corrupt neither it, nor the Mathematica kernel (i.e. it should be possible to call the function again from Mathematica after it has been interrupted)

  • How to Redirect a Python Console output to a QTextBox

    - by krishnanunni
    Hello, I'm working on developing a GUI for the recompilation of Linux kernel. For this I need to implement 4-5 Linux commands from Python. I use Qt as GUI designer. I have successfully implemented the commands using os.system() call. But the output is obtained at the console. The real problem is the output of command is a listing that takes almost 20-25 min continuous printing. How we can transfer this console output to a text box designed in Qt. Can any one help me to implement the setSource() operation in Qt using source as the live console outputs.

  • Python - werid behavior

    - by orokusaki
    I've done what I shouldn't have done and written 4 modules (6 hours or so) without running any tests along the way. I have a method inside of /mydir/__init__.py called get_hash(), and a class inside of /mydir/utils.py called SpamClass. /mydir/utils.py imports get_hash() from /mydir/__init__. /mydir/__init__.py imports SpamClass from /mydir/utils.py. Both the class and the method work fine on their own but for some reason if I try to import /mydir/, I get an import error saying "Cannot import name get_hash" from /mydir/__init__.py. The only stack trace is the line saying that __init__.py imported SpamClass. The next line is where the error occurs in in SpamClass when trying to import get_hash. Why is this?

  • How to merge/crosslink Javadoc?

    - by Tom Wheeler
    If you have the standard Javadoc for a few different projects, how can you process them to create a single unified set of documentation in which everything is cross-linked? Ideally, the result would be similar to the documentation for the various modules in the NetBeans Platform: http://bits.netbeans.org/dev/javadoc/index.html but I've looked at their build scripts and they're predicated on you building everything from source. I'm looking for something which could also handle linking in Javadoc for third-party libraries, so I'd imagine it would need to be a post-processing operation. I can't be the first person to ever want this. Any ideas?

  • Any book that covers internals of recent versions of Unix OS

    - by claws
    This summer I'm getting into UNIX (mostly *BSD) development. I've graduate level knowledge about operating systems. I can also understand the code & read from here and there but the thing is I want to make most of my time. Reading books are best for this. From my search I found that these two books The Design and Implementation of the 4.4 BSD Operating System (1996) "Unix Internals: The New Frontiers" by Uresh Vahalia (1996) (See here for 2nd edition) are like established books on UNIX OS internals. But the thing is these books are pretty much outdated. So, Is there any recent books that covers internals of recent Unix OS? How about books on other Unix operating systems? They seem to be recent than above books but how close are they to OpenBSD/FreeBSD? Solaris 10 and OpenSolaris Kernel Architecture, 2 edition (July 20, 2006) HP-UX 11i Internals (February 1, 2004) I really don't prefer HP-UX as its not open source.

  • Why do people still use C these days? [closed]

    - by Joshua
    C++ is clearly a far superior language than C, since it has many features that C lacks (although, C++'s object model isn't as ideal as say C#'s). With the coming off the new C++0x standard, why hasn't C been phased out to obscurity? C++ has been around for so long, since the '80s. The Linux kernel has already been ported to C++ with negligible performance differences. I believe, with no evidence, that larger program structures benefit in performance if written in C++ than in C, if only because of object interaction. Don't get me started on "objects-in-C!" libraries, which are all a terrible hack. (Not that C++'s object model is the most ideal, but it is almost up to snuff with C# using common ad-hoc techniques.)

  • Tool to diagonalize large matrices

    - by Xodarap
    I want to compute a diffusion kernel, which involves taking exp(b*A) where A is a large matrix. In order to play with values of b, I'd like to diagonalize A (so that exp(A) runs quickly). My matrix is about 25k x 25k, but is very sparse - only about 60k values are non-zero. Matlab's "eigs" function runs of out memory, as does octave's "eig" and R's "eigen." Is there a tool to find the decomposition of large, sparse matrices? Dunno if this is relevant, but A is an adjacency matrix, so it's symmetric, and it is full rank.

  • mounting without -o loop

    - by jumpinjoe
    Hi, I have written a dummy (ram disk) block device driver for linux kernel. When the driver is loaded, I can see it as /dev/mybd. I can successfully transfer data onto it using dd command, compare the copied data successfully. The problem is that when I create ext2/3 filesystem on it, I have to use -o loop option with the mount command. Otherwise mount fails with following result: mount: wrong fs type, bad option, bad superblock on mybd, missing codepage or helper program, or other error What could be the problem? Please help. Thanks.

  • xcodeproj merge fails when adding new group

    - by user1473113
    I'm currently using Xcode with Git, and I'm experiencing some troubles during the merge process of my xcodeproj. Developer1 create a new group in Xcode file arborescence the commit and push. Developer2 on an other computer do the same with an other group name, commit and pull(with merge). The xcodeproj of Developer 2 become unreadable with Xcode. But when I create a new file or just drag and drop files from finder to repository, the merge succeed. Did someone has experienced that kind of trouble? I'm using in .gitattributes: *.pbxproj -crlf -diff merge=union # Better to treat them as binary files. *.pbxuser -crlf -diff -merge *.xib -crlf -diff -merge and in my .gitignore # Mac OS X *.DS_Store *~ # Xcode *.mode1v3 *.mode2v3 *.perspectivev3 *.xcuserstate project.xcworkspace/ xcuserdata/ *.xcodeproj/* !*.xcodeproj/project.pbxproj !*.xcodeproj/*.pbxuser # Generated files *.o *.pyc *.hi #Python modules MANIFEST dist/ build/ # Backup files *~.nib \#*# .#*

  • GWT tries to load a deleted module

    - by Dmitry
    I am using Eclispe with Google plugin for AppEngine and GWT. Recently I created a test GWT module, but eventually it has been deleted from the project and I can not find any sign of it in the project now. However, whenever I run the web app locally, I get in console the following message: Loading modules com.piq.exemity.Test [ERROR] Unable to find 'com/XXXXXX/Test.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source? Has anyone got any idea where it can be hiding?

  • Using netlink to obtain arp entries only returns stale entries

    - by Ben
    I'm currently trying to retrieve reachable neighbors from the arp table in a user space program written in c. I've looked through the source code to the "ip neigh" command (ipneigh.c) and it appears that I should use the flag NUD_REACHABLE. struct { struct nlmsghdr n; struct ndmsg r; } req; memset(&req, 0, sizeof(req)); req.n.nlmsg_len = NLMSG_LENGTH(sizeof(struct ndmsg)); req.n.nlmsg_flags = NLM_F_REQUEST | NLM_F_ROOT; req.n.nlmsg_type = RTM_GETNEIGH; req.r.ndm_state = NUD_REACHABLE; However, when I look at the data returned from the kernel, I only have stale entries. In fact, no matter what I put for req.r.ndm_state it seems to return only entries marked as stale by ip neigh. The remainder of my code is modeled after this example: http://linux-hacks.blogspot.com/2009/01/sample-code-to-learn-netlink.html

  • Show extra info for Preference screens when CheckboxPreference summary field is not enough long?

    - by Pentium10
    I have situation when you can enabled/disable modules for my Android application. For this I use a CheckboxPreference screen. This is all good, but the summary field gets cut off if longer descriptions are added than 2 lines. Suppose I have 4-5 lines of description available for each module, I would like to display this in a helper window. I tried to bind a click event to the CheckboxPreference, but that fires for the whole line, so not only when the checkbox is clicked, and more, where ever you click on the line the checkbox is toggled. So now I am wondering if this can be fixed. So if the user needs more info, just taps the text and the helper opens up, and if want to toggle the settings it taps the checkbox. How would you do it? I am open to other ideas too, if they do work.

  • Strategy for developing a multi function asp.net web application

    - by user247023
    I'm about to start a new project and want some advice on how to implement. I need a web application which contains a booking module for reserving timeslots, and a time management module which will enable employees to clock in / clock out. If I am writing an update to the time managment module, I don't want to disrupt the booking engine availability by releasing a new solution containing both modules. to make things more difficult, there is some shared functionality like common users, roles and security. Here's a suggestion I've gotten, which sounds a bit cruddy, but may be functional. Write a 'container' web application which consists of basically a frame, and authentication / security features. This then has links which, will load the 2 independantly built and released web applications into the frame. I can see that say, if I wanted to update the time management module, I would only need to build and release this separately, and the rest of the solution would be 'untouched' Any better alternatives?

  • How to 'hide' spurious "declared but never used" warnings?

    - by Roddy
    I'm using the C++Builder compiler which has a minor bug that certain static const items from system header files can cause spurious "xyzzy is declared but never used" warnings. I'm trying to get my code 100% warning free, so want a way of masking these particular warnings (note - but not by simply turning off the warning!) Also, I can't modify the header files. I need a way of 'faking' the use of the items, preferably without even knowing their type. As an example, adding this function to my .cpp modules fixes warnings for these four items, but it seems a bit 'ad-hoc'. Is there a better and preferably self-documenting way of doing this? static int fakeUse() { return OneHour + OneMinute + OneSecond + OneMillisecond; }

  • How do I get property injection working in Ninject for a ValidationAttribute in MVC?

    - by jaltiere
    I have a validation attribute set up where I need to hit the database to accomplish the validation. I tried setting up property injection the same way I do elsewhere in the project but it's not working. What step am I missing? public class ApplicationIDValidAttribute : ValidationAttribute { [Inject] protected IRepository<MyType> MyRepo; public override bool IsValid(object value) { if (value == null) return true; int id; if (!Int32.TryParse(value.ToString(), out id)) return false; // MyRepo is null here and is never injected var obj= MyRepo.LoadById(id); return (obj!= null); } One other thing to point out, I have the Ninject kernel set up to inject non-public properties, so I don't think that is the problem. I'm using Ninject 2, MVC 2, and the MVC 2 version of Ninject.Web.MVC. Thanks!

  • Understanding top output in Linux

    - by Rayne
    Hi, I'm trying to determine the CPU usage of a program by looking at the output from Top in Linux. I understand that %us means userspace and %sy means system/kernel etc. But say I see 100%us. Does this mean that the CPU is really only doing useful work? What if a CPU is tied up waiting for resources that are not avaliable, or cache misses, would it also show up in the %us column, or any other column? Thank you.
