• Ubuntu Software Center 12.04 Does not install Software

  - by Lester Miller

  I have just loaded Ubuntu 12.04 on a computer. I am new to Ubuntu. I am using an automatic proxy server. When I pick a software package to install the program I input my password. The progress icon displays for a few seconds and then it stops. I tried to load different programs and always the same problem. I can go out on the network through firefox so I know I have a network connection. I do not see any errors or anything. Not sure what to do. I am thinking about switching over to SUSE

• SQL Server 2012 : Changes to system objects in RC0

  - by AaronBertrand

  As with every new major milestone, one of the first things I do is check out what has changed under the covers. Since RC0 was released yesterday, I've been poking around at some of the DMV and other system changes. Here is what I have noticed: New objects in RC0 that weren't in CTP3 Quick summary: We see a bunch of new aggregates for use with geography and geometry. I've stayed away from that area of programming so I'm not going to dig into them. There is a new extended procedure called sp_showmemo_xml....(read more)

• Authenticating clients in the new WCF Http stack

  - by cibrax

  About this time last year, I wrote a couple of posts about how to use the “Interceptors” from the REST starker kit for implementing several authentication mechanisms like “SAML”, “Basic Authentication” or “OAuth” in the WCF Web programming model. The things have changed a lot since then, and Glenn finally put on our hands a new version of the Web programming model that deserves some attention and I believe will help us a lot to build more Http oriented services in the .NET stack. What you can get today from wcf.codeplex.com is a preview with some cool features like Http Processors (which I already discussed here), a new and improved version of the HttpClient library, Dependency injection and better TDD support among others. However, the framework still does not support an standard way of doing client authentication on the services (This is something planned for the upcoming releases I believe). For that reason, moving the existing authentication interceptors to this new programming model was one of the things I did in the last few days. In order to make authentication simple and easy to extend,  I first came up with a model based on what I called “Authentication Interceptors”. An authentication interceptor maps to an existing Http authentication mechanism and implements the following interface, public interface IAuthenticationInterceptor{ string Scheme { get; } bool DoAuthentication(HttpRequestMessage request, HttpResponseMessage response, out IPrincipal principal);} An authentication interceptors basically needs to returns the http authentication schema that implements in the property “Scheme”, and implements the authentication mechanism in the method “DoAuthentication”. As you can see, this last method “DoAuthentication” only relies on the HttpRequestMessage and HttpResponseMessage classes, making the testing of this interceptor very simple (There is no need to do some black magic with the WCF context or messages). After this, I implemented a couple of interceptors for supporting basic authentication and brokered authentication with SAML (using WIF) in my services. The following code illustrates how the basic authentication interceptors looks like. public class BasicAuthenticationInterceptor : IAuthenticationInterceptor{ Func<UsernameAndPassword, bool> userValidation; string realm;  public BasicAuthenticationInterceptor(Func<UsernameAndPassword, bool> userValidation, string realm) { if (userValidation == null) throw new ArgumentNullException("userValidation");  if (string.IsNullOrEmpty(realm)) throw new ArgumentNullException("realm");  this.userValidation = userValidation; this.realm = realm; }  public string Scheme { get { return "Basic"; } }  public bool DoAuthentication(HttpRequestMessage request, HttpResponseMessage response, out IPrincipal principal) { string[] credentials = ExtractCredentials(request); if (credentials.Length == 0 || !AuthenticateUser(credentials[0], credentials[1])) { response.StatusCode = HttpStatusCode.Unauthorized; response.Content = new StringContent("Access denied"); response.Headers.WwwAuthenticate.Add(new AuthenticationHeaderValue("Basic", "realm=" + this.realm));  principal = null;  return false; } else { principal = new GenericPrincipal(new GenericIdentity(credentials[0]), new string[] {});  return true; } }  private string[] ExtractCredentials(HttpRequestMessage request) { if (request.Headers.Authorization != null && request.Headers.Authorization.Scheme.StartsWith("Basic")) { string encodedUserPass = request.Headers.Authorization.Parameter.Trim();  Encoding encoding = Encoding.GetEncoding("iso-8859-1"); string userPass = encoding.GetString(Convert.FromBase64String(encodedUserPass)); int separator = userPass.IndexOf(':');  string[] credentials = new string[2]; credentials[0] = userPass.Substring(0, separator); credentials[1] = userPass.Substring(separator + 1);  return credentials; }  return new string[] { }; }  private bool AuthenticateUser(string username, string password) { var usernameAndPassword = new UsernameAndPassword { Username = username, Password = password };  if (this.userValidation(usernameAndPassword)) { return true; }  return false; }} This interceptor receives in the constructor a callback in the form of a Func delegate for authenticating the user and the “realm”, which is required as part of the implementation. The rest is a general implementation of the basic authentication mechanism using standard http request and response messages. I also implemented another interceptor for authenticating a SAML token with WIF. public class SamlAuthenticationInterceptor : IAuthenticationInterceptor{ SecurityTokenHandlerCollection handlers = null;  public SamlAuthenticationInterceptor(SecurityTokenHandlerCollection handlers) { if (handlers == null) throw new ArgumentNullException("handlers");  this.handlers = handlers; }  public string Scheme { get { return "saml"; } }  public bool DoAuthentication(HttpRequestMessage request, HttpResponseMessage response, out IPrincipal principal) { SecurityToken token = ExtractCredentials(request);  if (token != null) { ClaimsIdentityCollection claims = handlers.ValidateToken(token);  principal = new ClaimsPrincipal(claims);  return true; } else { response.StatusCode = HttpStatusCode.Unauthorized; response.Content = new StringContent("Access denied");  principal = null;  return false; } }  private SecurityToken ExtractCredentials(HttpRequestMessage request) { if (request.Headers.Authorization != null && request.Headers.Authorization.Scheme == "saml") { XmlTextReader xmlReader = new XmlTextReader(new StringReader(request.Headers.Authorization.Parameter));  var col = SecurityTokenHandlerCollection.CreateDefaultSecurityTokenHandlerCollection(); SecurityToken token = col.ReadToken(xmlReader);  return token; }  return null; }}This implementation receives a “SecurityTokenHandlerCollection” instance as part of the constructor. This class is part of WIF, and basically represents a collection of token managers to know how to handle specific xml authentication tokens (SAML is one of them). I also created a set of extension methods for injecting these interceptors as part of a service route when the service is initialized. var basicAuthentication = new BasicAuthenticationInterceptor((u) => true, "ContactManager");var samlAuthentication = new SamlAuthenticationInterceptor(serviceConfiguration.SecurityTokenHandlers); // use MEF for providing instancesvar catalog = new AssemblyCatalog(typeof(Global).Assembly);var container = new CompositionContainer(catalog);var configuration = new ContactManagerConfiguration(container); RouteTable.Routes.AddServiceRoute<ContactResource>("contact", configuration, basicAuthentication, samlAuthentication);RouteTable.Routes.AddServiceRoute<ContactsResource>("contacts", configuration, basicAuthentication, samlAuthentication); In the code above, I am injecting the basic authentication and saml authentication interceptors in the “contact” and “contacts” resource implementations that come as samples in the code preview. I will use another post to discuss more in detail how the brokered authentication with SAML model works with this new WCF Http bits. The code is available to download in this location.

• Authenticated SMTP Using System.Net.Mail

  - by The Official Microsoft IIS Site

  Using system.net.mail to send email messages from your web site makes life so easy. In the old days of Classic ASP you often had to rely on 3rd party components such as AspMail from serverobjects.com or AspEmail from persists.com. While they were very capable products and are still widely used today it added an additional layer of complexity to your programming. If you ever had to move a site from one server to another there was always a risk the components were not in place which would cause problems...(read more)

• Which operating systems book is good as a quick refresher?

  - by rdasxy

  I am preparing for a technical interview and need to review the basics of major operating systems concepts. We used Tanenbaum's Modern Operating Systems in school for our operating systems course, which is a good book, but too long to be reviewed in the course of a few days. For an example, I am looking for what Programming Interviews Exposed is to Weiss's Data Structures & Algorithm Analysis. Any suggestions?

• Is Oracle Solaris 11 Really Better Than Oracle Solaris 10?

  - by rickramsey

  If you want to be well armed for that debate, study this comparison of the commands and capabilities of each OS before the spittle starts flying: How Solaris 11 Compares to Solaris 10 For instance, did you know that the command to configure your wireless network in Solaris 11 is not wificonfig, but dladm and ipadm for manual configuration, and netcfg for automatic configuration? Personally, I think the change was made to correct the grievous offense of spelling out "config" in the wificonfig command, instead of sticking to the widely accepted "cfg" convention, but loathe as I am to admit it, there may have been additional reasons for the change. This doc was written by the Solaris Documentation Team, and it not only compares the major features and command sequences in Solaris 11 to those in Solaris 10, but it links you to the sections of the documentation that explain them in detail. - Rick Website Newsletter Facebook Twitter

  I am programming a 2D sidescroller in python and pygame and am having trouble making a bullet go farther than just farther than the player. The bullet travels straight to the ground after i fire it. How, in python code using pygame do I make the bullet go farther. If you need code, here is the method that handles the bullet firing: self.xv += math.sin(math.radians(self.angle)) * self.attrs['speed'] self.yv += math.cos(math.radians(self.angle)) * self.attrs['speed'] self.rect.left += self.xv self.rect.top += self.yv

• Forced Learning

  - by Ben Griswold

  If you ask me, it can be a little intimidating to stand in front of a group and walkthrough anything remotely technical. Even if you know “Technical Thingy #52” inside and out, public speaking can be unsettling.  And if you don’t have your stuff together, well, it can be downright horrifying. With that said, if given the choice, I still like to schedule myself to present on unfamiliar topics. Over the past few months, I’ve talked about Aspect-Oriented Programming, Functional Programming, Lean Software Development and Kanban Systems, Domain-Driven Design and Behavior Driven Development.  What do these topics have in common? You guessed it: I was truly interested in them. I had only a superficial understanding of each. Huh?  Why in the world would I ever want to to put myself in that intimidating situation? Actually, I rarely want to put myself into that situation but I often do as I like the results.  There’s nothing remotely clever going on here.  All I’m doing is putting myself into a compromising situation knowing that I’ll likely work myself out of it by learning the topic prior to the presentation.  I’m simply time-boxing myself to learn something new while knowing there are negative repercussions if I fall short. So, I end up doing tons of research and I learn bunches to ensure I have my head firmly wrap around the material before my talk. I’m not saying I become an expert overnight (or over a couple of weeks) but I’ll definitely know enough to be confident and comfortable and I’ll know more than enough to ensure the audience will learn a thing or two from me. It’s forced learning and though it might sound a little scary to some, it works for me. Now I could very easily rename this post to something like Fear Is My Motivator because, in a sense, fear of failure and embarrassment is what’s driving my learning. However, I’m the guy signing up for the presentation and since the entire process is self-imposed I’m not sure Fear deserves too much credit.  Anyway…

• How do you structure computer science University notes?

  - by Sai Perchard

  I am completing a year of postgraduate study in CS next semester. I am finishing a law degree this year, and I will use this to briefly explain what I mean when I refer to the 'structure' of University notes. My preferred structure for authoring law notes: Word Two columns 0.5cm margins (top, right, bottom, middle, left) Body text (10pt, regular), 3 levels of headings (14/12/10pt, bold), 3 levels of bulleted lists Color A background for cases Color B background for legislation I find that it's crucial to have a good structure from the outset. My key advice to a law student would be to ensure styles allows cases and legislation to be easily identified from supporting text, and not to include too much detail regarding the facts of cases. More than 3 levels of headings is too deep. More than 3 levels of a bulleted list is too deep. In terms of CS, I am interested in similar advice; for example, any strategies that have been successfully employed regarding structure, and general advice regarding note taking. Has latex proved better than Word? Code would presumably need to be stylistically differentiated, and use a monospaced font - perhaps code could be written in TextMate so that it could be copied to retain syntax highlighting? (Are notes even that useful in a CS degree? I am tempted to simply use a textbook. They are crucial in law.) I understand that different people may employ varying techniques and that people will have personal preferences, however I am interested in what these different techniques are. Update Thank you for the responses so far. To clarify, I am not suggesting that the approach should be comparable to that I employ for law. I could have been clearer. The consensus so far seems to be - just learn it. Structure of notes/notes themselves are not generally relevant. This is what I was alluding to when I said I was just tempted to use a textbook. Re the comment that said textbooks are generally useless - I strongly disagree. Sure, perhaps the recommended textbook is useless. But if I'm going to learn a programming language, I will (1) identify what I believe to be the best textbook, and (2) read it. I was unsure if the combination of theory with code meant that lecture notes may be a more efficient way to study for an exam. I imagine that would depend on the subject. A subject specifically on a programming language, reading a textbook and coding would be my preferred approach. But I was unsure if, given a subject containing substantive theory that may not be covered in a single textbook, people may have preferences regarding note taking and structure.

• Oracle Database 11g Helps Control Exponential Data Growth

  - by [email protected]

  The 2010 ESG annual customer survey is now available. As part of it, ESG interviewed 300 customers about their IT priorities and, unsurprisingly, "Manage Data Growth" is top of the list. Perhaps less self-evident is the proposed solution to target this prime concern: "Often overlooked because it is a database platform, Oracle Database 11g offers additional capabilities such as automatic storage management (ASM), advanced data compression, and data protection that make managing data growth much easier for organizations of any size." The paper goes on to discuss these capabilities and highlights their potential benefits. Oracle Database 11g Helps Control Exponential Database Growth - a worthwhile read for anyone having to deal with rapidly increasing amounts of data. Download your free copy here.

• Which points should be covered in basic Bachelors' level C++ course?

  - by Gulshan

  I have a young lecturer friend who is going to take the C++ course for the bachelors' degree in CS. He asked me for some suggestions regarding how the course should be organized. Now I am asking you. I have seen many trends in universities which leads to a nasty experience of C++. So, please suggest from a professional programmer's point of view. For your information, the students going to take the course, have taken course like "Introduction to programming with C" in previous semester.

• Does The College Matter?

  Does it matter all that much about what college you go to, to get a degree in computer programming/computer science? I didn't do all that well in high school, I actually barely graduated with a general High School Diploma. So getting into a decent college could be difficult. Companies won't deny you just because you got your degree at a college they have never heard of or a community college will they?

• book and resource about vanilla OpenGL ES 2.0 development

  I Found this book but it talks about an SDK created by the author rather than pure simple OpenGL ES 2.0; this sounds more like a commercial to me than a good book for programming, i would like to start with just OpenGL ES 2.0 without talking about anything else: can you give me a good advice on this? A good book or on-line resource. I'm also interested in cross platform development with OpenGL ES, in particular Android and iOS.

• How to implement line of sight restriction in actionscript?

  - by Michiel Standaert

  I have a problem with a game i am programming. I am making some sort of security game and i would like to have some visual line of sight. The problem is that i can't restrict my line of sight so my cops can't see through the walls. Below you find the design, in which they can look through windows, but not walls. Further below you find an illustration of what my problem is exactly. this is what it looks like now. As you can see, the cops can see through walls. This is the map i would want to use to restrict the line of sight. So the way i am programming the line of sight now is just by calculating some points and drawing the sight accordingly, as shown below. Note that i also check for a hittest using bitmapdata to check whether or not my player has been spotted by any of the cops. private function setSight(e:Event=null):Boolean { g = copCanvas.graphics; g.clear(); for each(var cop:Cop in copCanvas.getChildren()) { var _angle:Number = cop.angle; var _radians:Number = (_angle * Math.PI) / 180; var _radius:Number = 50; var _x1:Number = cop.x + (cop.width/2); var _y1:Number = cop.y + (cop.height/2); var _baseX:Number = _x1 + (Math.cos(_radians) * _radius); var _baseY:Number = _y1 - (Math.sin(_radians) * _radius); var _x2:Number = _baseX + (25 * Math.sin(_radians)); var _y2:Number = _baseY + (25 * Math.cos(_radians)); var _x3:Number = _baseX - (25 * Math.sin(_radians)); var _y3:Number = _baseY - (25 * Math.cos(_radians)); g.beginFill(0xff0000, 0.3); g.moveTo(_x1, _y1); g.lineTo(_x2, _y2); g.lineTo(_x3, _y3); g.endFill(); } var _cops:BitmapData = new BitmapData(width, height, true, 0); _cops.draw(copCanvas); var _bmpd:BitmapData = new BitmapData(10, 10, true, 0); _bmpd.draw(me); if(_cops.hitTest(new Point(0, 0), 10, _bmpd, new Point(me.x, me.y), 255)) { gameover.alpha = 1; setTimeout(function():void{ gameover.alpha = 0; }, 5000); stop(); return true; } return false; } So now my question is: Is there someone who knows how to restrict the view so that the cops can't look through the walls? Thanks a lot in advance. ps: i have already looked at this tutorial by emanuele feronato, but i can't use the code to restric the visual line of sight.
