  • If .net sha1 hash expects a byte array, and php sha1() wants a string, can I match the results?

    - by lynn
    I have a set of bytes I want to apply an sha1 hash to. One hash will be in .net, the other in PHP. Then I'll test to see if they match. In .net, you can create a byte array and use sha.ComputeHash(). byte[] data = new byte[DATA_SIZE]; byte[] result; SHA1 sha = new SHA1CryptoServiceProvider(); // This is one implementation of the abstract class SHA1. result = sha.ComputeHash(data); In PHP, you call sha1($string). I can't do anything about the .net side of the code, but how can I get the same hash out of PHP that .net will generate? Please note: I am ONLY able to work on the PHP side of this. The .net stuff is fixed and can't be modified. Thanks!

  • Why does subshell not inherit exported variable (PS1)?

    - by amn
    After some debugging I finally narrowed down the problem as to why my X session xterm prompt does not appear according to my PS1 setting. If I run sh -c env, it doesn't even show PS1 in the list. Why? export PS1='test' sh -c env # No PS1 in the list, default prompt appearance (shell name + version) Substituting sh with bash yields same result, alas the behavior appears to be the same for both shells/modes. As far as I understood from man bash, the environment resulting from command run by shell with -c should include the exported variables. And it does - exporting FOOBAR results in FOOBAR listed in env run by subshell. It appears that the story is different if the variable is PS1 however. What is going on? I want my prompt propagated throughout the process tree and system. For matters sake, it is set in /etc/profile.d/user.sh (a file I created myself) with the following: PS1='\u@\H \w \$ ' export PS1 I am running Arch Linux (updated yesterday.)

  • How to make multiple wires quickly in Verilog?

  • c# Generic overloaded method dispatching ambiguous

    - by sebgod
    Hello, I just hit a situation where a method dispatch was ambiguous and wondered if anyone could explain on what basis the compiler (.NET 4.0.30319) chooses what overload to call interface IfaceA { } interface IfaceB<T> { void Add(IfaceA a); T Add(T t); } class ConcreteA : IfaceA { } class abstract BaseClassB<T> : IfaceB<T> { public virtual T Add(T t) { ... } public virtual void Add(IfaceA a) { ... } } class ConcreteB : BaseClassB<IfaceA> { // does not override one of the relevant methods } void code() { var concreteB = new ConcreteB(); // it will call void Add(IfaceA a) concreteB.Add(new ConcreteA()); } In any case, why does the compiler not warn me or even why does it compile? Thank you very much for any answers.

  • A c# Generics question involving Controllers and Repositories

    - by UpTheCreek
    I have a base repository class which contains all the common repository methods (as generic): public abstract class BaseRepository<T, IdType> : IBaseRepository<T, IdType> My repositories from this base e.g.: public class UserRepository : BaseRepository<User, int>, IUserRepository I also have a base controller class containing common actions, and inherit from this in controllers. The repository is injected into this by DI. E.g. public class UserController : BaseController<User> { private readonly IUserRepository userRepository; public UserController (IUserRepository userRepository) { this.userRepository= userRepository; } My question is this: The base controller needs to be able to access the repository methods that are defined in the base repository. However I'm passing in via DI a different repository type for each controller (even though they all inherrit from the base repository). How can the base controller somehow access the repository that is passed in (regardless of what type it is), so that it can access the common base methods?

  • What tool can I use to definitely kill a process on Windows?

    - by Moak
    Can anyone recommend an application (preferably usb-portable that doesn't require setup) That really kills a process immediately in windows XP? I ask this because often when I need to use the XP task manager it seems to want to go about it "the polite way" and sometimes crashed programs don't quit or take a minute to shut down. I need a real stone cold killer, not a pushover-could-you-please-quit-now-no?-ok-sorry-program Edit I'm sorry if it wasn't clear previously but I did mean the situation when even the "End process" command in Process tab of the task manager doesn't kill a program, however one of the answers did point me to the "End Process Tree" command which I've never noticed (when right clicking on the process)

  • Windows' "open with" with java and a jar file

    - by Boldewyn
    I use the rest-client to test REST APIs. It is basically just a .jar file, that is called via java -jar rest-client.jar. The rest-client uses two file extensions, in my case .rcq, to store data in files. I want to let the explorer open .rcq files with java -jar rest-client.jar <infile>, however, if I configure it (via GUI) to use the JAR alone, it obviously doesn't work. I'd be fine with touching HKEY_CLASSES_ROOT for this, as well, but don't know the exact syntax. By the way: It's WinXP.

  • How can I organize movies, with IMDB import and fields for tags?

    - by fluxtendu
    How can I organize movies on Windows? Features wanted: IMDB import fields: director, genre, year, actors,... covers manage DVD / BD / ripped AVIs, MKV moving/renaming files according fields I want to achieve something like: M:\Movies\Director\year. title (genre).avi A syntax that lets me choose how I organize my files (like foobar2000 & mp3 files) according IMDB and personal tags would be great. Auto fetch covers and listing of not-yet-ripped/yet-to-be-seen/wanted/loaned movies (txt, HTML or whatever) would be some nice features too.

  • Zend_Form and Liskov Substitution Principle

    - by blockhead
    A very common pattern I see (I'm picking on Zend Framework, only because I was dealing with it at the moment of this question), is something like this: class My_Form extends Zend_Form { public function init() { $this->addElement(); } } Zend_Form is not an abstract class, but is perfectly usable on its own. This seems to be "recommended" as place to "encapsulate" your forms into a nice class. Does this violate the Liskov Substitution Principle? Each subclass of Zend_Form will have a wildy different behavior than the base class. Would it be better to use composition for this, or am I totally misunderstanding this principle?

But It points to In the Microsoft Internet Security and Acceleration Server 2006 management console, expand the array name, and then click the Firewall Policy node. When I open the ISA Server 2006 Management Console, I can not show the expand list, how can I force ISA to show the expandable tree to start Firewall Policy? Could any one please help me to do this ? Note : I have administrator permission for my account. Thanks in advance :)

  • Life Cycle Navigator?

    - by C.W.Holeman II
    In many environments the file system directory structure and naming conventions attempt to allow one to use a file manager to navigate the life cycle of a document. This overloading of functions makes it difficult for users to handle the complexity. A file browser is a tool that lets the user navigate among files located in a directory structure to find a specific file. Whereas, when given a specific file, a life cycle navigator is a tool that lets the user navigate its life cycle from source to published copy and across versions. Does a Life Cycle Navigator exit? I see a user pointing at an object: Left mouse button displays the document Right mouse button has a Life Cycle Navigator (LCN) The LCN displays a tree for a specific document within a file manger, for example: Published 3.2 Current 3.1 3.0 +2.x +1.x +Archived +All Source Draft 3.2 Current 3.1 3.0 +2.x +1.x +Archived +All +Work Flow +Properties Or from a command line: $ lcn x.pdf --open_source_document | my_favorite_editor $ lcn x.pdf --show_published_version_info $ lcn x.pdf --show_previous_publish_versions_info See also, Life Cycle Navigator.

  • Java generics question

    - by user247866
    So I have 3 classes. Abstract class A Class B extends class A independent Class C In class D that contains the main method, I create a list of instances of class B List<B> b = methodCall(); // the method returns a list of instances of class B Now in class C I have one method that is common to both A and B, and hence I don't want to duplicate it. I want to have one method that takes as input an instance of class A, as follows: public void someMethod(List<A> a) However, when I do: C c = new C(); c.someMethod(b); I get an error that some-method is not applicable for the argument List<B>, instead it's expecting to get List<A>. Is there a good way to fix this problem? Many thanks!

  • clear contents from matched column of data in another sheet

    - by Peta
    I have a column of email addresses on sheet 2 col A (but I could put them on sheet 1 if it would make it easier / faster) that I want to remove from sheet 1 col D if matched (there may be 2 or more occurences of the same email to be removed/cleared). (1000s of rows in each sheet). After all day searching forums I’m getting more confused & can't find what I'm looking for. Not sure whether to use .match or .find & .ClearContents & the syntax for iterating through. Thanks very much in anticipation Peta

  • rsync : Read input from a file and sync accordingly

    - by Dheeraj
    I have a text file which contains the list of files and directories that I want to copy (one on a line). Now I want rsync to take this input from my text file and sync it to the destination that I provide. I've tried playing around with "--include-from=FILE" and "--file-from=FILE" options of rsync but is is just not working I also tried pre-fixing "+" on each line in my file but still it is not working. I have tried coming with various filter PATTERNs as outlined in the rsync man page but it is not working. Could someone provide me correct syntax for this use case. I've tried above things on Fedora 15, RHEL 6.2 and Ubuntu 10.04 and none worked. So i am definitely missing something. Many thanks.

  • .htaccess rewrite all queries to static page

    - by user127219
    I have an account where hundreds of inbound links to their calender are showing up as 404 (they moved their site to a new platform). I would like to make a wildcard redirection of all URLs with a query to their old event calender to land on a new static page, and do the same for their webstore queries. I've tried several variations, but can't seem to get it to work. CASE 1: I need to redirect URLs like these (note the difference between "showDay" and "showWeek"): apps/calendar/showWeek?calID=5107976&year=2011&month=7&day=10 apps/calendar/showDay?calID=5107976&year=2011&month=9&day=10 To: http://domain.com/events/ CASE 2: And also URLs like these: apps/webstore/products/show/1927074 TO: http://subdomain.domain.com/ I can't seem to get the syntax right to take all of the URLS and redirect them. I'm looking for the equivalent of a wildcard like "apps/calendar/*" would give you at a command line. Any help is appreciated!

  • Making OR/M loosely coupled and abstracted away from other layers.

    - by Genuine
    Hi all. In an n-tier architecture, the best place to put an object-relational mapping (OR/M) code is in the data access layer. For example, database queries and updates can be delegated to a tool like NHibernate. Yet, I'd like to keep all references to NHibernate within the data access layer and abstract dependencies away from the layers below or above it. That way, I can swap or plug in another OR/M tool (e.g. Entity Framework) or some approach (e.g. plain vanilla stored procedure calls, mock objects) without causing compile-time errors or a major overhaul of the entire application. Testability is an added bonus. Could someone please suggest a wrapper (i.e. an interface or base class) or approach that would keep OR/M loosely coupled and contained in 1 layer? Or point me to resources that would help? Thanks.

  • Puppet exported resource naming

    - by Tim Brigham
    I am working on setting up a collection of Splunk nodes to be deployed by Puppet. One of the steps in this process is importing the trusts to allow these nodes to automatically find each other. I've looked over several options and it appears that exported resources are the only ready way to go for this to work. The files I need to create are under /opt/splunk/etc/auth/distServerKeys//trusted.pem. The source for each of these files should be /opt/splunk/etc/auth/distServerKeys/trusted.pem, one per node. What syntax do I need to make this work? The samples I've looked at all appear to have the same source and destination file name.

  • C#: reflection alternative for switch on enum in order to select namespace/class

    - by Am
    Hi, I have an interface named IHarvester. There are 3 implementations of that interface, each under their own namespace: Google Yahoo Bing A HarvesterManager uses the given harvester. It knows the interface and all 3 implementations. I want some way of letting the class user say in which harvester it wants to use. And in the code select that implementation, without a switch-case implementation. Can reflection save my day? Here is the code bits: // repeat for each harvester namespace Harvester.Google { public abstract class Fetcher : BaseHarvester, IInfoHarvester {...} } public enum HarvestingSource { Google, Yahoo, Bing, } class HarvesterManager { public HarvestingSource PreferedSource {get;set;} public HarvestSomthing() { switch (PreferedSource) .... // awful... } } Thanks.

  • Manipulating individual rows of a datagrid

    - by pfranchise
    Hey, recently I started working on a webpage that has a datagrid. I understand how to add datasources and that sort of thing, or at least I am starting to get it. But my question is about manipulating individual rows or cells. Is that only possible during the databind event handler, that is the only place I have been able to do it so far. I am sure there is a more abstract way of doing the things I want to do, but there are times where I just want to say Datagrid.add(row). I mean, if the datagrid is made up of a certain object type, can I make a new object of that type and just chuck it on the end? I am still new to this stuff, so perhaps what I want to do would defeat the purpose of this added abstraction, but figured I would ask around. Thanks for any advice, tips, or tricks people feel like sharing. Edit: for clarification I am using c#, entity framework, asp.net, and an SQL database.

  • Two domains hosted on the same server with different root folder shows up the same homepage

    I have hosted two domains from GoDaddy at Linode VPS. They are mobiletoast.com and lesseltechnologies.com Thought the latter site has a separate index folder, whenever I navigate to it, I get the homepage of mobiletoast.com The strange thing is, I see the expected page (It works), when I open the site from my mobile phone. But when I open the site from my PC (any browser, without any cache, hard refresh), I get the homepage of mobiletoast.com The Linode support team says, they see the correct "It works" page. But I am not able to see that page.

  • Create samba shortcut from command line

    - by neurolysis
    I'm currently wanting to deploy a setup to around 300 Macs. I have most of it scripted, but I'm having trouble creating a working alias to a samba share from the command line. I tried copying it from one Mac to another, but it loses its status as an alias, and instead OSX opens it in TextEdit. From a hexdump, it also looks like it has machine-specific information. So, say I wanted to create an alias to 'smb://server/share' on the desktop from the command line, how would I do that? I have also tried a tell in AppleScript, but it complained about the syntax (specifically, too many slashes, seemingly taking about smb://). Thanks.

  • How can I see the structure of a webpage inline?

    - by Coldblackice
    How can I see a webpage's structure "inline" with the visual representation of the actual page, all at once? I'm trying to understand HTML layout better, but it's hard to get a feel for it, even having the source open on a separate monitor, because there's just so much expansive and miscellaneous code. I suppose I could sift through it, clean it up, and set up some type of custom collapsible tree system, but that would take too long for the amount of pages I'd like to get a quick view of the layout/structure of. For reference, I'm using Firefox for my internet browsing.

  • installing packages without sudo access

    - by whitman
    Is there an easy way to install packages with a large dependency tree, provided that you don't have superuser access? For instance, say I wanted to install firefox. Firefox has a ton of dependencies, each of which have their own dependencies, etc. Installing these the "./configure; make; make install" way would take forever. Is there an option I can give apt-get to make it install in a personal directory? Or is there a way to hack it to do all the heavy lifting for me?
