How Firewalls Work
Just a general question here. If a network isn't protected by a firewall, how does a virus spread to your computer? Does another computer just have to send a UDP packet or open TCP stream with the virus on it? Could another computer get access to my shell and run scripts on my computer remotely?

.Net Source Debugging on Windows 7
We are trying to debug through a Sql Server CE issue on a Windows 7 Enterprise RTM desktop running the .Net Framework 3.5, SP1. The application is crashing consistently and we are trying to set up .Net Framework debugging for Visual Studio 2008, SP1. Using the scattered resoures around the internet, we set the options: - Symbol Server = http://referencesource.microsoft.com/symbols - Tools->Options->Debugging->Just My code = Disabled - Tools->Options->Debugging->Enable .Net Framework Debugging = Enabled - Tools->Options->Debugging->Enabled Source Server Support = Enabled When we run the application, we are unable to step into the source and we still get the error "There is no source code at this location." We do get the stack trace indicating that the Sql Server CE symbols have loaded and when we click the details on the error dialog, we get a message indicating that the Sql Server CE pdb file was loaded correctly. I did find a blog post indicating that this is an issue with the symbols not being updated for Windows 7 yet here: [http://software.intel.com/en-us/blogs/2009/09/07/visual-studio-2008-sp1-net-framework-source-debugging/][1] However, I cannot find anything official about this issue. Is there anything I'm missing? Has anyone heard anything about Windows 7 Symbols being incorrect and/or when they will be updated? Thanks in advance.

Conflicting results when unit testing MVC controller
I'm writing unit tests (using NUnit) for my MVC 2 controllers, and am following examples in the Pro ASP.net MVC 2 Framework book by Steven Sanderson (great book, btw). However, I've run into problems, which I think are just due to my lack of understanding of NUnit. Here's an excerpt, with the irrelevant parts removed: [Test] public void Cannot_Save_Invalid_Event() { ... repository.Setup(x => x.SaveEvent(evt)).Callback(Assert.Fail); ... repository.Verify(x => x.SaveEvent(evt)); } This test is passing for me, although from what I understand, those two statements should directly conflict with each other. The second one wasn't there originally, but I put it in to verify that it was passing for the right reasons. From what I understand, my repository is set up to fail if "repository.SaveEvent(evt)" is called. However, later in the test, I try to verify that "repository.SaveEvent(evt)" was called. Since it passes, doesn't this mean that it was both called, and not called? Perhaps those statements don't act as I suspect they do. Can someone explain how these two statements are not opposites, and how they can both exist and the test still pass?

How can I break into the development business scene if I'm the new kid on the block?
I'm about 1 semester short of graduating from college with my Systems Engineer degree. I've started my own software development company here in a country in South America last week, and so far I managed to land myself a nice account. I have to build a simple enough program that will take me 6-7weeks to complete and I'll charge 2000$. 40% up front and the rest on completion. While this is great and I'm really excited about my first project (*Hell it's a landmark for any professional!*), I'm already setting my eye on landing projects that will be visible for other companies to see. I've spoken with many people in my trade around town and it seems there are two companies that manage the big accounts with other small companies scrounging around for the scraps. How can I break this so called fellowship that is pretty much a monopoly here? Any and all suggestions will be massively appreciated.

Subdomain locations on server
I have had a look to see if this has been answered but to no avail. Perhaps is so obvious that it doesn't need answering? I have made a subdomains folder on my server where I want to keep all my subdomains in. Does this folder have to be in the public_html folder or can I have this folder on the root (same level as the public_html folder)? I know this works as I have tried it, but is this good practice? The reason I ask is because the subdomains can be access like a subfolder e.g. www.mywebsite.com/subdomains/aNewSubdomain Many thanks

How can I make a search form that searches for snippets of text?
Okay, so, I want to make a search form on my website that when a user searches something, the results come up on a new page and those results are snippets of code, no database. Umm, so something like 'this is a search result <br> this is a link under it'; 'this is another search result <br> this is a link under it'; 'this is a 3rd, bob has a cat <br> this is a link under it' and basically the search form would search through these snippets of code and show the results, so lets say i typed in "bob has a cat" then the search form goes through the snippets of code and on the results page displays this is a 3rd, bob has a cat <br> http://thelink.net I will pray for you on Christmas Eve if you answer this hard-to-explain question. :)

Operation Systems and common stacks
I have to learn something about Operating Systems (especially Linux), but I have problems with the different types of stacks.. There are Interrupt, System, User, Kernel ,... stacks. Where are the differences, implementations and where are they stored (special-CPU-sections, RAM,..)? How many are there? (one per cpu, cpu-core, process, thread, kernel)

buttons turn off everytime I make a change
Here is a [demo][1] of part of an application I am currently working on. Please follow the steps below: - Step 1: On left hand side you will see a green plus button, click on it and it opens up a modal window. - Step 2: In modal window there is a search bar, type in "AAA" and submit search, you will see a bunch of rows appear. - Step 3: In the first row click on the "Add" button, you will see a bunch of letter buttons appear on the right hand side with a button highlighted green. - Step 4: Now click on the "Add Question" button, this will add a row below where it copies the option and answer control from top into the row. Now repeat the steps 1 to 3 again except in step 3, add a different row by clicking on "Add" button in a different row. Problem: The problem is that after you repeat steps 1-3, you will see that the letter buttons within the row you have just appeanded, turns back to white again (in other words all letter buttons are turned off), this should not happen, the letter buttons within the row should not be affected at all if you are using the option and answer control on top. So my question is what is causing the letter buttons within the row(s) to be turned off after you have clicked on the "Add" button for the top option and answer control?

Variable naming discussion: C# vs JavaScript?
I was reading [this post][1] and it left me wondering... Why is it wrong to use a variable named `_` in `C#` for a intensively used library (should one ever surface), but perfectly fine to use `$` for the same purpose under `JavaScript`?

Does C have classes?
Okay, you may call me a noob but I'm realling confused. My ex classmate paid me to write a program in C. She gave me the task and it said something like "blah blah blah make at least TWO CLASSES, write at least ONE CONSTRUCTOR and rewrite at least ONE METHOD" it says that word by word. And then I told her "this is C++ not C" she said "but we're learning C" I ignored it and wrote the program in c++ and sent to her as I thought she didn't know what she was talking about. She said "it doesn't work on code blocks, and wtf is cout <<" and then she sent me a chunk of code that they write and instead of cout and cin there was printf and scanf. It had to be C. So, I rewrote the program with printf and scanf and she still says codeblocks throw errors (I still left classes as task demanded). I want to ask wtf? Does C have classes? Or is there a misunderstanding or something?

Clear list of distinctions between an API, Library, Framework, and Toolkit in Java
I've lots of varying definitions for the following terms, but I'm not clear as to the distinctions between them. Would someone please clarify the following and the distinction(s) between each item? - API - Library - Framework - Toolkit I'm not seeing what makes an API different from a library or a toolkit from a framework or a framework from a library.

Patterns for making c++ code easy to test
Should you design your code to make testing easier? And if so how to design **c++** code so that it is easy to test. - How do you apply dependency-injection in c++? - Should I implement the classes using a pure interface class as the base in order to simplify the creation of fake test objects? - That would force me into making a lot of **virtual** methods. Will that affect performance? - What else should I think about when designing for testability in c++?

Constructing Min/Max Binary Heap
Given an inorder-traversal list, what's the best way to create a Binary Min/Max Heap? I'm trying to confine with the following constructs: 1. No array to be used in the binary-heap. Implementation is node-based. `BinaryNode { value, parent, l_child, r_child }` 2. Let's just stick to Max-Heap. **Question:** Can we do better than standard insertion that involves BubbleDown.

Modifying Spring beans programmatically
I'm currently developing a web application. I know some basics of Spring, however I haven't been working with it that much, hence I've decided to improve my Spring-skills and I've faced a problem that I can't really find a good solution for. I'd like to implement in my app a feature that will allow the user to configure everything without touching any config file (e.g. spring beans), basically the person that wants to deploy, launch and use the app should only copy the .WAR file into for example tomcat and all the configuration should be done within the app (like in OpenFire for example). So I imagine that the user deploys the app goes to certain URL and everything is done through UI, he is being asked about some parameters (e.g. DB connection details) once all details are given everything is stored in cfg file, app restarted and the configuration process is over. I wanted to have all the configuration details in spring beans, but I've discovered that I can't really change them programmatically (one solution would be to modify the file 'out of spring' and reload the app context after wards - is that good approach?). Another one would be to store xml file in WEB-INF for example and save the data there once it's gathered from the user, but then how to load the data from non-bean file into application context? Any advices appriciated!

What's the best optimization you've ever used?
One of biggest optimizations I've used is regard to this question: http://stackoverflow.com/questions/1152414/import-from-text-file-to-sql-server-database-is-ado-net-too-slow with the initialized version, insert each row per query use ADO.NET, I was able to insert about 100 rows/second. When I switched to batch insert, it rose to 1000 rows/second, and then, BulkCopy, I can get, about 7000 rows/second. All in same machine. 70 times better and even smaller, more-readable code. So, what's the best optimization you've ever used to improve your code? Optimization means better tactic/strategy, not premature optimization :)

Silverlight Disabling, Hiding all controls in a container
I'm trying to create a method to disable and hide all controls inside a container. For testing purposes I'm trying to do this with a Grid first but I would like something to work with any container type. At first I was going to do this for the whole view but I realized that the `UserControl` class does not have a Children collection (or at least not by that name and I couldn't find anything like it), so I decided to go for a Grid instead, since that is how it's gonna go in 90% of the cases I'll use it. Keeping in mind that this would be for any type of control I tried something like foreach (Control c in myGrid.Children) { c.IsEnabled = false; c.Visibility = Visibility.Collapsed; } By doing this I realized that the Children property is a `UIElementCollection`, therefore the loop couldn't be used like that. I changed the type of c in the `foreach` to from `Control` to `UIElement`, and that presented antoher problem: `UIElement` doesn't have the `IsEnabled` property. So after playing around with my code a bit, I came to have this method: private void DisableHideControls(UIElementCollection source) { foreach (UIElement ctrl in source) { ctrl.Visibility = System.Windows.Visibility.Collapsed; Control c; c = ((ctrl as TextBox) != null) ? (TextBox)ctrl : null; if (c != null) c.IsEnabled = false; } } I figured I had to convert the `UIElement` to Control, and since I wasn't sure every `UIElement` can be safely converted to a `Control` I tried first with `TextBox`. This has 2 problems: 1. I would need to have to have all the types of controls I need to disable in there 2. I don't think it would disable/hide controls inside other controls (for example a `TextBox` inside a `TabGroup`) So, is there a way to disable and hide all controls in a container (and their children) that could be type independent?

I had NO .NET experience and he had zero Linux experience... I had the app done in 2 days. At two weeks, the boss called the competition done even though my competition wasn't complete yet.

Best way to organize back-end for .NET project I'm doing(C#)
I am currently working on a large project. This project has about 20 relevant tables that are all related. I have a back-end set up where Admins can add new items, edit them, view them etc.... I took this project over from someone else, so in the interest of getting things done in a timely fashion, I'm currently handling everything in 2 pages. The basic layout of both pages is a sidebar including 17 different categories(Products, Brands, Users etc...), with the content of the page displaying the relevant info for the selected category. I am using the first page to display the info. When I click on say Products, the products load in a table from new to old, paginated in the content portion with options to edit/delete for each, as well as an option to add a new item. I'm handling the delete on this page, but the edit and add are on the second page. The second page is the same layout, but the content portion will either be a blank form with the relevant fields, or those fields pre-populated for the item from the edit command on the previous page Now, I am doing this for all different categories in the code-behind of each page. Even though everything works well, and is not even slow really, I don't like the lack of organization, even though the different categories are clearly separated and organized properly in the code-behind. I'm wondering the best way to divide this up. Should I just make a page for each category and have each of those pages handle both displaying as well as editing/adding? Then I can share the common functions through a central base page? Or should I make use of the ASP user controls, and create a control for each category to handle this stuff, again sharing a base control? I'm just not sure which is the most efficient, or even the more standard way to approach this. I'd like to get some feedback before I decide how to break this down, and would appreciate any other suggestions as well. Thanks

How to plot a 3d graph starting from a set of points as a ground XY base
This question might seem a little strange but for my purposes is not that crazy. Its easy but I need you to follow me. The aim -------- My aim is plotting a tridimensional graph. The problem ----------- The problem is the material I have in my hands to start building this graph. Actually I have a collection of points in the 2D space (thus tuples of two real ordered values). Consider a moment to have these collection of points stored into an array and now consider to plot them on a 2D diagram. You will just have a nice sparse view of these points. Well, the second step is this: consider the surface with these points and create a third axis orthogonal to the plane where those points are drawn. The aim is assigning to every point a numerical scalar value (using a function that accepts the couple and returns a numerical value). So the graph should show bars starting from every point and having a specific value according to the assignment function. How can I achieve this in Mathematica? A little note ------------- Basically my points in the 2d space are also connected by a graph. Is it possible to connect the top of the bars to the top of other bars whose base point are connected together in the 2d graph? Some other notes ---------------- My graph doesn`t have to be a surface but just a collection of bars placed on a plane in the exact place where the correspondent point they refer to is located. But if you have a good hint how to draw a surface other than bars, it will be gladly accepted. I hope I was clear. I would like to point that I have Mathematica 8 so all functionalities are available. Thank you.

How to plot a 3d graph starting from a set of points as a ground XY base === This question might seem a little strange but for my purposes is not that crazy. Its easy but I need you to follow me. The aim -------- My aim is plotting a tridimensional graph. The problem ----------- The problem is the material I have in my hands to start building this graph. Actually I have a collection of points in the 2D space (thus tuples of two real ordered values). Consider a moment to have these collection of points stored into an array and now consider to plot them on a 2D diagram. You will just have a nice sparse view of these points. Well, the second step is this: consider the surface with these points and create a third axis orthogonal to the plane where those points are drawn. The aim is assigning to every point a numerical scalar value (using a function that accepts the couple and returns a numerical value). So the graph should show bars starting from every point and having a specific value according to the assignment function. How can I achieve this in Mathematica? A little note ------------- Basically my points in the 2d space are also connected by a graph. Is it possible to connect the top of the bars to the top of other bars whose base point are connected together in the 2d graph?

Custom columns using Django admin
I had a model `Data`, associated to a table like that.

How to develop web based voice chat app in C#
I'm looking for a set of library in C# that could help me develop a web based voice chat app. I would prefer to avoid using Flash or Silverlight if i can. From searching the internet i found WebRTC, libjingle, FreeSwitch, Asterisk could possibly provide what i need, but none is written for C#. Could someone point me to the right direction ?

tool for creating interpreters using java
I am currently looking for tools(either software programs or frameworks) on how to make a compiler using java. I already have the GUI prepared. But I still don't have a clue on how to start creating a compiler. Maybe anyone could give me links or tutorials in creating compilers using java.I am not looking for the exact source code really, but tips, and algorithms on how to create compilers going through the lexical,syntactical and semantic analysis.

Use a SMTP proxy to modifiy mail content
I have a commercial software sending mails and I have modify their content. I can't access to source code of the software. A simplified example : Mail sent by the software : TO : mike@mail.com, john@mail.com. BODY : "Hello #guy# !". I want to modify the content so that mike@mail.com receive "Hello Mike !" and john@mail.com receive "Hello John !". The idea is to use a proxy to transform the mails before forwarding them to the SMTP server. What's the best way to do that ? The solution will be hosted on Linux and has to be in Java or PHP which are the technologies used on the project.

What are good books to study C/C++ programming in Windows?
I'm an experienced Java/C# developer. I studied C/C++ in university but have never used them to build any non-trivial software. Now I'm interested in learning about C/C++ programming in Windows and looking for good books to get started. Specifically, I want to learn about Win32 API, MFC, COM, event hook, screen capturing, multithreading, and networking. Good books that cover many of these topics, even at introductory level (sufficient to start coding in the respective topic & explore more later), are of more interest to me than books covering only one or two of those areas in depth. What are good books which meet these criteria?

Need help in registration/sign-up (OAuth/OpenId with Facebook and Yahoo) and sign in
I have an application that will accept both Facebook and Yahoo registrations as well as normal registration (providing username, email, password). I'm confused on the Facebook and Yahoo side of the registration. The scenario is, upon clicking the Facebook/Yahoo registration links, users will be redirected to the provider's site for login, then redirect to our site with a form pre-filled with their email address and other profile data (photo/profile pic, birthday, gender, address, etc). With OpenId, as far as I know, you can't have access to most of those information since its concern is authentication. So, on the signup part, I'm thinking of using OAuth. However, I saw on Yahoo's registration for an API key (http://developer.yahoo.com/oauth/ or http://developer.yahoo.com/dashboard/createKey.html) that you can't access the user's email under Yahoo! Profiles. I need that email address to save on my accounts database. Then, on sign in, I plan to use OpenID both for Facebook and Yahoo. Is that ok? Using OAuth for sign-up, and OpenID for login/sign-in? Or can I use OAuth for signing in? (I know you can do this on Facebook with their Javascript SDK, but I am not aware about Yahoo's).

How to change all occurances of a word in all files in a directory
I was in the process of creating a `User` class where one of the methods was `get_privileges();`. After hours of slamming my head into the keyboard, I finally discovered that the previous coder who I inherited this particular database spelled the word "**privileges**" as "**privelages**" in the MySQL database, and thus also everywhere in the hundreds of files that access these "**privelages**" it is spelled that way. Is there a way in Linux (*Ubuntu Server*) that I can go through every place in the `/var/www` folder and replace "**privelages**" with "**privileges**", so that I don't have to deal with this typo and code around it?

Building a common set of methods that can operate on any linq table
**Problem:** We make extensive use of a repository pattern to facilitate read/write operations on our datastore (MS SQL using LINQ) across multiple applications and subsections of functionality. We have series of methods that all do something similar to each other. For example, we have the ProcessAndSortXXXXX class of methods. private static IEnumerable<ClassErrorEntry> ProcessAndSortClassErrorLog(IQueryable<ClassErrorDb> queryable, string sortOrder) { var dynamic = queryable; if (!String.IsNullOrEmpty(sortOrder.Trim())) { dynamic = dynamic.OrderBy(sortOrder); } return dynamic .Select(l => new ClassErrorEntry(l.Id) { ClassId = l.ClassId, Code = l.Code, Message = l.Message, Severity = l.Severity, Target = l.Target } ); } ...and... private static IEnumerable<ClassTimerLogEntry> ProcessAndSortClassTimerLog(IQueryable<ClassTimerDb> queryable, string sortOrder) { var dynamic = queryable; if (!String.IsNullOrEmpty(sortOrder.Trim())) { dynamic = dynamic.OrderBy(sortOrder); } return dynamic .Select(l => new ClassTimerLogEntry(l.Id) { ClassName = l.ClassName, MethodName = l.MethodName, StartTime = l.StartTime, EndTime = l.EndTime, ParentId = l.ParentId, ExecutionOrder = l.ExecutionOrder } ); } As you can tell by the code, they're all very similar until you look at the signature and then get to the the return statement where we're building out the instances of the ClassErrorEntry and ClassTimerLogEntry. I want to build a utility method that I'll add into the base class that all of the repositories inherit from. I want to be able to pass in arguments that can be used to instantiate the objects and pack them into the returning IEnumerable. I found [this post](http://weblogs.asp.net/scottgu/archive/2008/01/07/dynamic-linq-part-1-using-the-linq-dynamic-query-library.aspx) by [ScottGu](http://weblogs.asp.net/scottgu/) and that gets me most of what I need. It looks like this (from the sample in the documentation): var query = db.Customers. Where("City = @0 and Orders.Count >= @1", "London", 10). OrderBy("CompanyName"). Select("new(CompanyName as Name, Phone)"); Here's where I get stuck, though. I need a pointer or suggestion how I can pass in the LINQ tables and DataContext in a generic fashion so I can build out the dynamic query. If I were to mock up the signature in pseudocode I think it would look something like this: protected internal IEnumerable ProcessAndSort(IQueryable source, string selectClause, string whereClause, string orderByClause); I realize that the finished signature may look different as we figure this out. Thank you!

Having trouble understanding ninject (or just IOC container in general) over factory DI?
Okay, so recently I've been reading into ninject but I am having trouble understanding what makes it better over why they referred do as 'poor man's' DI on the wiki page. The sad thing is I went over all their pages on the wiki and still don't get it =(. Typically I will wrap my service classes in a factory pattern that handles the DI like so: public static class SomeTypeServiceFactory { public static SomeTypeService GetService() { SomeTypeRepository someTypeRepository = new SomeTypeRepository(); return = new SomeTypeService(someTypeRepository); } } Which to me seems a lot like the modules: public class WarriorModule : NinjectModule { public override void Load() { Bind<IWeapon>().To<Sword>(); Bind<Samurai>().ToSelf().InSingletonScope(); } } Where each class would have it's associated module and you Bind it's constructor to a concrete implementation. While the ninject code is 1 less line I am just not seeing the advantage, anytime you add/remove constructors or change the implementation of an interface constructor, you'd have to change the module pretty much the same way as you would in the factory no? So not seeing the advantage here. Then I thought I could come up with a generic convention based factory like so: public static TServiceClass GetService<TServiceClass>() where TServiceClass : class { TServiceClass serviceClass = null; string repositoryName = typeof(TServiceClass).ToString().Replace("Service", "Repository"); Type repositoryType = Type.GetType(repositoryName); if (repositoryType != null) { object repository = Activator.CreateInstance(repositoryType); serviceClass = (TServiceClass)Activator.CreateInstance(typeof (TServiceClass), new[]{repository}); } return serviceClass; } However, this is crappy for 2 reasons: 1) Its tightly dependent on the naming convention, 2) It assumed the repository will never have any constructors (not true) and the service's only constructor will be it's corresponding repo (also not true). I was told hey this is where you should use an IoC container! And thus my research began...but I am just not seeing it and am having trouble understanding it... Is there some way ninject can automatically resolve constructors of a class without a specific declaration such that it would be great to use in my generic factory (I also realize I could just do this manually using reflection but that's a performance hit and ninject says right on their page they don't use reflection). Enlightment on this issue and showing how it could be used in my generic factory would be much appreciated!

Having trouble understanding ninject (or just IOC container in general) over factory DI? === Okay, so recently I've been reading into ninject but I am having trouble understanding what makes it better over why they referred do as 'poor man's' DI on the wiki page. The sad thing is I went over all their pages on the wiki and still don't get it =(. Typically I will wrap my service classes in a factory pattern that handles the DI like so: public static class SomeTypeServiceFactory { public static SomeTypeService GetService() { SomeTypeRepository someTypeRepository = new SomeTypeRepository(); return = new SomeTypeService(someTypeRepository); } } Which to me seems a lot like the modules: public class WarriorModule : NinjectModule { public override void Load() { Bind<IWeapon>().To<Sword>(); Bind<Samurai>().ToSelf().InSingletonScope(); } } Where each class would have it's associated module and you Bind it's constructor to a concrete implementation. While the ninject code is 1 less line I am just not seeing the advantage, anytime you add/remove constructors or change the implementation of an interface constructor, you'd have to change the module pretty much the same way as you would in the factory no? So not seeing the advantage here. Then I thought I could come up with a generic convention based factory like so: public static TServiceClass GetService<TServiceClass>() where TServiceClass : class { TServiceClass serviceClass = null; string repositoryName = typeof(TServiceClass).ToString().Replace("Service", "Repository"); Type repositoryType = Type.GetType(repositoryName); if (repositoryType != null) { object repository = Activator.CreateInstance(repositoryType); serviceClass = (TServiceClass)Activator.CreateInstance(typeof (TServiceClass), new[]{repository}); } return serviceClass; } However, this is crappy for 2 reasons: 1) Its tightly dependent on the naming convention, 2) It assumed the repository will never have any constructors (not true) and the service's only constructor will be it's corresponding repo (also not true). I was told hey this is where you should use an IoC container! And thus my research began...but I am just not seeing it and am having trouble understanding it... Is there some way ninject can automatically resolve constructors of a class without a specific declaration such that it would be great to use in my generic factory (I also realize I could just do this manually using reflection but that's a performance hit and ninject says right on their page they don't use reflection). Enlightment on this issue and showing how it could be used in my generic factory would be much appreciated!

How to autoload extended classes?
I am planning to use PHP's autoload function to dynamicly load only class files that are needed. Now this could create a huge mess if every single function has a seperate file, So I am hoping and asking is there a way to have related classes remain in 1 class file and still be auto-loaded function __autoload($class_name){ include('classes/' . $class_name . '.class.php'); } Let's say there is a class name animals and then another class named dogs. Dogs class extends animals class, now if I were to call the dogs class but NOT call the animals class, would the animals class file still be loaded?

CMD.exe C# Emulator?
I've been trying very hard to automatically ssh into a Linux server. What's crazy, is that I can create a .bat script, that will do it, but I have to be there physically, to type in the password. I've tried automating this using System.Diagnostics.Process object in c# to no end. There is no way, I've found to make this object allow you to see the password prompt. It out puts every line up until that point, and then doesn't output any more lines. cmd.exe, does really well at allow you to jump process to process in a script. I consolidates everything into one screen, and just prompts you for things such as passwords, and then you type them in. Is any simple way, in C#, to make cmd.exe think you are a human being typing in it, so I can simulated this programmatically? Otherwise, System.Diagnostics.Process, doesn't seem to offer a way to interacted with at process that outputs a password prompt. You never get to see the login prompt that clearly happens when you run the same thing in cmd.exe

strange java socket problem on windows
I've a strange problem with a java server application running on a windows machine; sometimes the SocketChannel I just obtained by ServerSocketChannel.accept immediately returns an error when I try to read data from it - the strange thing is that at the same time the client that started the incoming connection is stuck waiting for the answer it expects to receive from the server, that is the pattern is something like this: 1. client from another machine calls connect, connect returns, client writes logon request, client starts waiting for logon response 2. server wakes up on accept, tries to read and fails immediately, so it closes the socket 3. client keeps on waiting, as if the connection was established and no data was flowing in this pattern keeps repeating for a while (the client eventually times out in a few seconds and retries again) until eventually logon succeeds some minutes later. Has anyone an explanation for this? This looks like some kind of resource exhaustion problem on the server side, but I really have no clear idea of what is going on because I can't reproduce the problem and all I had to understand what is going on is logfiles. TIA

Fixed-point unsigned division in C
I need an algorithm to do unsigned fixed-point division in C. I can use at most 32-bit words. I want to minimize the number of bits needed to represent the integer part while being able to use numbers in the range [0..15]. So apparently the minimum number of bits is 4. Problem is the algorithm which I came up only works using 5 bits. Because it compares the remainder with the divisor and then shifts the remainder until it is bigger than the divisor, if the divisor has the most significant bit 1, then the algorithm will do nothing but shift the remainder (it will never be bigger). Here's the code: int divu(int a, int b){ int pt_int, r, pt_frac=0; int i; pt_int = ((unsigned) a/b) << BITS_FRAC; r = (unsigned) a%b; for (i=BITS_FRAC; i>=0; i--){ if ((unsigned) r < b) r <<= 1; else{ r -= b; pt_frac += 01 << i; r <<= 1; } } return pt_int + pt_frac; } If you do have a solution but don't want to understand the code, please, just post it. :)

Currently they are fixed to the extreme left & right. The styling of these elements is handled by this **CSS file**: http://css.festival.co.nz/yk-minifier/72cdcb814eb3e3beaa50436a9f869b1c.css however I'm really unsure where to begin if I was to try and move the buttons to be on either side of the centre image.

Need help with libcurl username/password authentication.
I'm trying to access a secure webpage on one of our servers. The webpage is inside a .htaccess protected directory that requires a username and password. I'm trying to get libcurl to submit the authentication request so it can access the file. After finding some guidance in various places, I've come up with what I believe should work, but it doesn't. $url="https://www.myurl.com/htaccess_secured_directory/file.php"; $ch = curl_init($url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); curl_setopt($ch, CURLOPT_USERPWD, 'myusername:mypassword'); $result = curl_exec($ch); echo $result; The file.php file should simply echo "Hello World!", but the $result variable is coming up blank. Is there a way to get error messages back from curl? Am I doing something wrong? I've also used CURLLAUTH_ALL without success, but I believe I just have basic authorization anyway.

Convert this c# to vb.net

Persist User Data in ASP.NET MVC
Similar questions have been asked before but I'm still without an answer and have spent a decent amount of time trying to find one. The scenario is this. We have an ASP.NET MVC application which is using Forms Authentication / LINQ-to-SQL data model. Each user can be associated with 1 or more **Accounts**. Upon login, the application checks how many Accounts they're associated with. **0** = Go to error page and let them know they have no access <br /> **1** = Set The *User Data* to use that account <br /> **2 or more** = Go to a page which allows them to select which account they'd like to use (with ability to change during their visit) **How would you store this information?** Furthermore, I'd like to use this Account as the base for my controller actions. i.e. Data on subsequent pages they visit will be related to the Account they've selected. Singleton ***cough*** comes to mind but am unsure how to implement that. An approach which I'm currently investigating is a Base Controller that all controllers will inherit from that will 1. Check whether a user is logged in. 2. If so, check whether they have an Account Selected - No - redirect them to Account Selection page - Yes - proceed with original request What is a recommended/best-practice way of doing this? Thanks Marko

BackTracking Issue in DFS Java Maze Q?
Right now, I am dealing with an ArrayDeque functioning as a stack. I have one to represent my "steps taken" and one to represent my "current position." I need help to figure out how to backtrack all the way to the positions in which there is more than one option. Essentially, I need to trace the path of the maze so that it is left with ONLY the solution. Right now, my whole maze is covered with 'x's except ONLY the positions in which I ran into a wall (are changed back to 0's).

I am formatting my pictures as following, but the problem is that the pictures are like they were suppose to, but the text appear to be only by first image. <p style="float: left; clear: left"><img src="image.jpg" height="200px" width="200px" border="1px"></p> <p>Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text</p> <p style="float: left; clear: left"><img src="image.jpg" height="200" width="200" border="1px"></p> <p>Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text Text</p>

i´m using datagrid with ExtJs .net I bind an object to the store which contains member of enum type: enum Colors {red,yellow,black,brown} and where the enum type is loaded in the grid -> { header: "colors", width: 170, sortable: true, dataIndex: 'colors', editor: { xtype: 'textfield', allowBlank: true } }, When the grid is loaded up it displays just a numbers 2,3,1 for example instead of "red", "yellow" or "black" How can i print out enums values as a string ?

Unwanted Prefixing of Hyperlinks Internet Explorer [Javascript]
What's The Problem? Only in Internet Explorer (surprise) is my code executed incorrectly. The short crap of code below should append an "onclick" action to each "a" tag. This works wonderfully but look at the fifth line, it should set the second function argument to the value of the "href" attribute of the anchor tag. In WebKit, Mozilla etc. it's fine. If we set "href" to say "lorem_ipsum" then WebKit, Mozilla etc. retrieve the correct result and set the second function argument to "lorem_ipsum", Internet Explorer prefixes "http://www.some.site/" so we see "http://www.some.site/lorem_ipsum" reported as the second argument. Internet Explorer is incorrect as that is not the "href" attribute of the anchor tag's actual value. Anchors=Parent.getElementsByTagName("a"); Anchor=0; while(Anchor<Anchors.length){ Anchors[Anchor].onclick=function(){ Plot("",this.getAttribute("href")); return false; }; Anchor++; }; How can I get around this absurd problem? Would I need to strip away from the string everything before the final slash? That seems a long winded approach! Any Ideas?

Should I trust LinqDataSource to clean up properly?
Taking my first stab as using the OnSelecting method of LinqDataSource so that I can specify a more complex query, I wrote this: protected void CategoriesDataSource_OnSelecting(object sender, LinqDataSourceSelectEventArgs e) { using (DataLayerDataContext db = new DataLayerDataContext()) { e.Result = (from feed in db.Feeds where feed.FeedName.StartsWith("Google") select feed.MainCategory).Distinct(); } } The problem, of course, is that the using clause will Dispose the DataLayerDataContext. The 'solution' is to write it without it, but I'm afraid then that the context won't be disposed of in a timely fashion, that it will leave a bunch of connections open until garbage collection runs, and so on. I'm no expert in this area, so any comments on whether this is a real problem, or am I worried for naught?

Using facebook.katana aka facebook app from the code
i´m trying to achieve a solution where the app ask if facebook.katana aka facebook app is installed in your android phone, if it is installed, check if the user is logged, and if it's logged send a picture with a text (better if it is to a folder), if the user is not logged go to the facebook.katana.LoginActivity and log him, after that make the procedure. I have this working with a Web View, but i'm interested on how to do it using the app if possible, what i got so far is the uncompiled facebook.katana in this URL where i'm testing the activities: http://xt720.ru/miui-trans/apk-decompiled/Facebook/smali/com/facebook/katana/ I also know that an image can be attached to that app, since can start the facebook app using this: final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); emailIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); emailIntent.putExtra(Intent.EXTRA_STREAM,imageUri); emailIntent.setType("image/png"); emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Whatever"); startActivity(Intent.createChooser(emailIntent, "Send email using")); This method would be great for an email, but as it says it creates a chooser, but i don't want to let that option open. So i tried something like: Intent intent = new Intent("android.intent.category.LAUNCHER"); intent.setClassName("com.facebook.katana", "com.facebook.katana.LoginActivity"); startActivity(intent); Also you can use the ShareLinkActivity to add an extra to your intent like this: intent.putExtra(Intent.EXTRA_TEXT, "http://www.google.com/"); The problem is that i don't see how to attach the image to the katana, neither, how to add it to a folder, or how to add it through an application, of course this is much easier via facebook API for android, but like i said that's already done, i want to make it with the facebook App, i have tried, attaching the Bundle to the app as a parcelable, with the usual way it is done in the API, but not luck, this is the snippet: Bundle params = new Bundle(); params.putByteArray("picture", bitmapdata); params.putString("title", url); params.putString("message","Wathever message"); and try to send the params, also tried sending only the image, but not luck, maybe i'm not using the right class (see the uncopiled facebook.katana URL) or i´m attaching in a bad way the info, it should work somehow, cause it works for ACTION_SEND, so, anybody knows how to solve any of this problems: 1. Attach an image to the facebook.katana 2. Attach an image to the facebook.katana in a folder 3. Attach an image to the facebook.katana as an external app 4. Request the log status of the user to the facebook.katana (i think this would be automatically) 5. Attach the picture, title, message params to the facebook.katana.

Why wont this move effect work on my sprites when the fade effect does?
Could someone please explain why this doesn't want to work? It's a bit of decoration to go behind a logo. When the dMove var is commented out I get the appropriate line of squares fading in and out at random spots along the x = 78 axis, but when introduced nothing appears at all... private var floatBG:UIComponent = new UIComponent(); private function addDP(event:TimerEvent):void{ var dY:Number = 5+Math.ceil(Math.random()*60); var dSize:Number = Math.ceil(Math.random()*12); var dAlpha:Number = Math.random()*0.5 + 0.2 var dDuration:Number = Math.ceil(Math.random()*5000) + 1000; var d:Sprite = new Sprite(); d.graphics.beginFill(0x1C75BC,dAlpha); d.graphics.drawRect(78, dY, dSize,dSize); d.graphics.endFill(); floatBG.addChild(d); var dMove:Move = new Move(d); dMove.xBy = 300; dMove.duration = dDuration; dMove.play(); var dFade:Fade = new Fade(d); dFade.alphaFrom = 1; dFade.alphaTo = 0; dFade.duration = dDuration; dFade.play(); this.addElement(floatBG); } Also, what would be the best/correct method for destroying the sprites at the end of each cycle?

How to change ListActivity to ListFragment
I have a Pager adapter that will call a ListFragment like this: public Fragment getItem(int position) { Fragment fragment = new ListViewFragment(); // set arguments here, if required Bundle args = new Bundle(); fragment.setArguments(args); return fragment; Then I have a ListActivity that I want to change to ListViewFragment. public class ImageListActivity extends ListActivity implements RadioGroup.OnCheckedChangeListener { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.imagelist); RadioGroup radioGroup = (RadioGroup) findViewById(R.id.radioGroup); radioGroup.setOnCheckedChangeListener(this); setListAdapter(new ImageAdapter()); } public void onCheckedChanged(RadioGroup group, int checkedId) { ImageDownloader.Mode mode = ImageDownloader.Mode.NO_ASYNC_TASK; if (checkedId == R.id.correctButton) { mode = ImageDownloader.Mode.CORRECT; }else if (checkedId == R.id.randomButton) { mode = ImageDownloader.Mode.NO_DOWNLOADED_DRAWABLE; } ((ImageAdapter) getListAdapter()).getImageDownloader().setMode(mode); } } But I really cant put it to work.. Ive tried that: public class ListViewFragment extends ListFragment { int mNum; Context ctx; View v; static int p; /** * Create a new instance of CountingFragment, providing "num" * as an argument. */ static ListFragment newInstance(int num) { ListFragment f = new ListFragment(); // Supply num input as an argument. Bundle args = new Bundle(); args.putInt("num", num); f.setArguments(args); return f; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { v = inflater.inflate(R.layout.imagelist, container, false); ImageDownloader.Mode mode = ImageDownloader.Mode.NO_ASYNC_TASK; mode = ImageDownloader.Mode.CORRECT; ((ImageAdapter) getListAdapter()).getImageDownloader().setMode(mode); setListAdapter(new ImageAdapter()); return container; } } This always crash, I want to use this ImageAdapter that will populate listview with images.

Side-by-side execution and MS Unit Test
Environment here is C#/.Net 4. In my MS Unit Test unit test project I'm testing a piece of code which uses a COM dll for some date conversion calculations (this in turn uses some other COM DLLs so in all three COM DLLs are involved). When running in a normal application/service set-up, I have no problem getting the side-by-side execution to work through use of manifests linking to the COM dlls' assembly identities, but when trying to do the same from my unit test project, I always get failure due to 'class not registered' exceptions. Now, I've tried this already: - Embedding the test DLL manifest - Embedding both the test DLL manifest, the COM dlls manifests + the COM DLLs themselves But to no avail. So I'm wondering: how could I make the unit test environment aware of the COM linking through the manifests? To me, it seems like the DLL manifest linking isn't quite working (the EXE manifests are working fine), but usually those kinds of thoughts equals doing something wrong ... I'm usually pretty successful in searching for stuff like this, but on this one, I've had very few hits, and nothing which resembles this, so please, if you have any thoughts or input, do share :) And if elaboration is needed, please let me know. (I know, that the use of the COM dlls could probably be avoided by some dependency injection the right place, but for now I'd like to explore this case regarding unit testing a side-by-side setup). Kind Regards Jesper

Amazon S3 + CloudFront, 4TB Traffic/Month, 16k Concurrent Users
this is a copy of my question at the amazon aws forum (where no one answered yet :-) ). Maybe someone here can help me out. The post: https://forums.aws.amazon.com/thread.jspa?threadID=99124&tstart=0 The question: Dear Forum, i am currently in the lucky situation to set up a video delivery network system. Besides some other alternatives I really consider to use the Amazon AW Services for the job. I was thinking about using the S3 storage servers together with CloudFront (as a Load Balancer). My question is if someone has experience with that and if he could share some knowledge with me (and all the other readers of this thread). Some background data: 891 GB videos 4.4 TB download transfer / Month 5k to 16k concurrent users. It is VERY IMPORTANT that no user will have lag which can be traced back to the backend. Lag is only allowed to occur if there are problems on the user side. If more information is needed please let me know. Appendix: Hello, I also would like to know if it is possible to easily duplicate S3 instances. For example: cloudFront tells me that we are running over a certain amount of concurrent clients. A script launches a new S3 instance, copies all date from the original S3 to the new one and connects the new S3 to cloudFront. If the high peek goes down again, the S3 instance gets terminated, with all data on it. Is a scenario like this possible? And if not, how can I handle something like this with Amazon? ---- Thanks a lot in advance. :-) Markus

.NET windows service getting stopped abruptly
HI Guys, I have created a windows service which spawns three threads.The first thread wakes up every 15 sec, the second thread wakes up every min. and the third thread once in a day. My COde looks something like this: var timer1 = new Timer(); timer1.Elapsed += ProcessTimerEvent1; timer1.Interval = 60000; timer1.Start(); var timer2 = new Timer(); timer2.Elapsed += ProcessTimerEvent2; timer2.Interval = 15000; timer2.Start(); var timer3 = new Timer(); timer3.Elapsed += ProcessTimerEvent3; timer3.Interval = 86400000; timer3.Start(); From my event logs I can see that it is saying .NET Runtime 2.0 Error Reporting EVENTID:5000. I looked through the net and it says invalid operationexception. DO you guys think whether this stopping of service has to do anything with threads. And the other silly question is am I spawning 3 new threads everytime or the same threads gets up evey 15 sec or 1 min.

Web Client Programming
How do implement a simple web client that will fetch all the required embedded images. More like, if a web page contains the elements like img src=”abcd.gif”, the client should fetch the image file abcd.gif. The client should work with any standard web server. After the contents are fetched, if the html file is opened in a browser locally, it should display the page properly. The client will be invoked as follows:cilent http:// webserver /a.html. How do i go about?

Is this method of static file serving safe in node.js? (potential security hole?)
I want to create the simplest node.js server to serve static files. Here's what I came up with: fs = require('fs'); server = require('http').createServer(function(req, res) { res.end(fs.readFileSync(__dirname + '/public/' + req.url)); }); server.listen(8080); Clearly this would map `http://localhost:8080/index.html` to `project_dir/public/index.html`, and similarly so for all other files. My one concern is that someone could abuse this to access files outside of `project_dir/public`. Something like this, for example: http://localhost:8080/../../sensitive_file.txt I tried this a little bit, and it wasn't working. But, it seems like my browser was removing the ".." itself. Which leads me to believe that someone could abuse my poor little node.js server. I know there are npm packages that do static file serving. But I'm actually curious to write my own here. So my questions are: 1. Is this safe? 2. If so, why? If not, why not? 3. And, if further, if not, what is the "right" way to do this? My one constraint is I don't want to have to have an if clause for each possible file, I want the server to serve whatever files I throw in a directory.
