  • System.Web.Security.FormsAuthentication.Encrypt returns null

    - by Mustafakidd
    I'm trying to encrypt some userData to create my own custom IPrincipal and IIdentity objects using Forms authentication - I've serialized an object representing my logged in user to Json and created my FormsAuthentication ticket like so: string user_item = GetJsonOfLoggedinUser();/*get JSON representation of my logged in user*/ System.Web.Security.FormsAuthenticationTicket ticket = new System.Web.Security.FormsAuthenticationTicket(1, WAM.Utilities.SessionHelper.LoggedInEmployee.F_NAME + " " + WAM.Utilities.SessionHelper.LoggedInEmployee.L_NAME, DateTime.Now, DateTime.Now.AddMinutes(30), false, user_item); string encrypted_ticket = System.Web.Security.FormsAuthentication.Encrypt(ticket); HttpCookie auth_cookie = new HttpCookie( System.Web.Security.FormsAuthentication.FormsCookieName, encrypted_ticket); Response.Cookies.Add(auth_cookie); However, the string encrypted_ticket is always null. Is there a limit on the length of the user_item string? Thanks Mustafa

    Although title is the same problem is different. I've installed Ubuntu 14.04 Trusty on my HP EliteBook 6930p Notebook. And I was trying to create a bootable usb for my DELL XPS 15z. After successful creation of usb with usb-creator-gtk I plugged in bootable usb stick to DELL laptop. The error message was "Operation System not found". I tried several things but could not make it. When I check from working Ubuntu, I can see that usb is bootable and has files for installation.

  • Yelp Like Adjective Rating System

    - by clifgray
    I am building a website that has users list their outdoor adventures (skydiving, surfing, base jumping, etc) and the other people can comment on them. I want to have a rating system like Yelp which has "Useful, Funny, or Cool" but with different adjectives. I have thought of a few such as Daring, Adventurous, and Unique but I wanted to get some feedback on what a few other good adjectives would be. Also does anyone have experience with other such systems or advice for better systems? Primarily I just want the user to have somewhat more descriptive voting options than u and down or 1 though 5.

  • FluentPath: a fluent wrapper around System.IO

    .NET is now more than eight years old, and some of its APIs got old with more grace than others. System.IO in particular has always been a little awkward. Its mostly static method calls (Path.*, Directory.*, etc.) and some stateful classes (DirectoryInfo, FileInfo). In these APIs, paths are plain strings. Since .NET v1, lots of good things happened to C#: lambda expressions, extension methods, optional parameters to name just a few. Outside of .NET, other interesting things happened as well. For...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  • IBM System x3650 M2: Benchmark of Oracle's JDE 9.0 with Oracle VM

    - by didier.wojciechowski
    The IBM Oracle International Competency Center (ICC) in Denver, Colorado in a joint effort with the Oracle JD Edwards performance team was the first to execute a certified JD Edwards EnterpriseOne benchmark running on the new Intel® Xeon® processor 5500 series (Nehalem). This benchmark configuration included the IBM System x3650 M2, partitioned using Oracle Virtual Machine (VM), and Oracle's robust "Day in the Life" (DIL) test kit. In October, 2009 the benchmark scaled to 700 users with early code. In January 2010, with GA level code, the benchmark scaled successfully to 1000 users with sub-second response time.

  • Using Lazy<T> and abstract wrapper class to lazy-load complex system parameters

    - by DigiMortal
    .NET Framework 4.0 introduced new class called Lazy<T> and I wrote blog post about it: .Net Framework 4.0: Using System.Lazy<T>. One thing is annoying for me – we have to keep lazy loaded value and its value loader as separate things. In this posting I will introduce you my Lazy<T> wrapper for complex to get system parameters that uses template method to keep lazy value loader in parameter class. Problem with original implementation Here’s the sample code that shows you how Lazy<T> is usually used. This is just sample code, don’t focus on the fact that this is dummy console application. class Program {     static void Main(string[] args)     {         var temperature = new Lazy<int>(LoadMinimalTemperature);           Console.WriteLine("Minimal room temperature: " + temperature.Value);         Console.ReadLine();     }       protected static int LoadMinimalTemperature()     {         var returnValue = 0;           // Do complex stuff here           return true;     } } The problem is that our class with many lazy loaded properties will grow messy if it has all value loading code inside it. This code may be complex for more than one parameter and in this case it is better to use separate class for this parameter. Defining base class for parameters As a first step I will define base class for all lazy-loaded parameters. This class is wrapper around Lazy<T> and it also offers one template method that parameter classes have to override to provide loaded data. public abstract class LazyParameter<T> {     private Lazy<T> _lazyParam;       public LazyParameter()     {         _lazyParam = new Lazy<T>(Load);     }       protected abstract T Load();       public T Value     {         get { return _lazyParam.Value; }     } } It is also possible to extend Lazy<T> but I don’t prefer to do it as Lazy<T> has six constructors we have to take care of. Also I don’t like to expose Lazy<T> public interface to users of my parameter classes. Creating parameter class Now it’s time to create our first parameter class. Notice how few stuff we have in this class besides overridden Load() method. public class MinimalRoomTemperature : LazyParameter<int> {     protected override int Load()     {         var returnValue = 0;           // Do complex stuff here           return returnValue;     } } Using parameter class is simple. Here’s my test code. class Program {     static void Main(string[] args)     {         var parameter = new MinimalRoomTemperature();         Console.WriteLine("Minimal room temperature: " + parameter.Value);         Console.ReadLine();     } } Conclusion Lazy<T> is useful class that you usually don’t want to use outside from API-s. I like this class but I don’t like when people are using this class directly in application code. In this posting I showed you how to use Lazy<T> with wrapper class to get complex parameter loading code out from classes that use this parameter. We ended up with generic base class for parameters that you can also use as base for other similar classes (you have to find better name to base class in this case).

  • Event system architecture for networking when performance is concerned

    - by Vandell
    How should I design a system for an action game (think in Golden Axe) where events can happen remotely? I'm using TCP for this because the client is in flash. There's so many options, I can make a binary protocol (I don't like this idea, I found it to be too hard to mantain) but I was also thinking that passing jsons through clients and server can be slow (Is that a exaggerated concern?). What about the internal architecture for the server? And for the client? I'm really lost, If it's a question that is too big, please indicate me some material so I can formulate a better question next time.

  • Installing Ubuntu 12.04 on EFI system

    - by aniruddhabhide
    Fellas, need help. Trying to install Ubuntu 12.04 on laptop to dual boot alongside Win7. I have UEFI and GPT partitioning scheme. It has optional Legacy boot mode though. I can boot from Ubuntu USB/CD in both Legacy and UEFI modes. But when I reach partition selection step, it gives me error "ubi-partman failed with exit code 141". I searched forums for this but those who encountered this error said it was resolved when they detached one of two HDs in their system. But I have only one hard disk attached and I am sure Ubuntu's GRUB supports GPT. But looks like it is not able to read GPT partitions on my HD. Any help regarding this will be appreciated.

    - by Rana
    I am working on developing a website, where registered members will be able to write blog/tutorials and each registered site user will be a registered blogger automatically. Site news/announcements will be posted through it too. Now, will it be a wise idea to use wordpress for this purpose, or should I develop custom blogging system myself? Also, is there any impact if I use a subdomain for the blog section. user same domain (sub directory url) for the blog section. Looking forward to hear your feedback/comments/suggestions. Thanks.

  • Practical Meta Programming System (MPS)

    - by INTPnerd
    This is in regards to Meta Programming System or MPS by JetBrains. Thus far, from my efforts to learn how to use MPS, I have only learned its basic purpose and that it is very complex. Is MPS worth learning? Is there anyone who already effectively uses MPS to create their own languages and editors for those languages and uses these created editors as their primary way of programming? If so, what types of programs have they made with this? What are the advantages and disadvantages of working with MPS? What is the best way to learn MPS?

  • How to set Default Web Browser, Mail Client, Video Player & Music Player in the system

    - by Luis Alvarado
    I am trying to find the option that sets, for the whole system the default Web Browser, Mail Client, Video Player and Music Player instead of having to do it for each type of file. I knew where the option was in 11.04 but somehow I can not find it again. Just to not get anymore confused I am not talking about right clicking a file then changing the "Open With" to the one I want. The option I am looking for affects everything in general, so if I change, for example, the default video player to VLC, all movies will be watched with VLC. I am using Unity.

  • Harry Foxwell talks about "Oracle Solaris 11 System Administration: The Complete Reference"

    - by Glynn Foster
    In a previous blog entry, New Oracle Solaris 11 Administration book, I blogged about the fact that a new book has been written to provide an excellent resource for administrators starting to learn some of the new features in Oracle Solaris 11. Despite an extensive set of online resources from the Oracle Technology Network, it's also useful to have something in the bookshelf that you can quickly refer to - and Harry Foxwell and his team of co-authors have done just that. Check out the video below where Harry goes into detail about why the book was written, details about the target audience, and what he's excited about in Oracle Solaris 11. Best of all though, is the fact that this is a brilliant book for any inspiring Linux administrator who wants to start getting to know the Oracle Solaris operating system a little better.

  • System will not boot without USB thumb drive inserted

    - by agent154
    I've had this issue before when trying out Linux Mint, but I was unable to get any assistance. I was then lead to believe that it was a problem related to Mint, and not grub. I installed Ubuntu 12.04 tonight on a second partition alongside Windows 7. I installed from a USB stick, and everything went peachy until I rebooted without the stick in my tower. It now says: error: no such device: 20cec6ca-4024-4237-84c3-2dba3c851497 grub rescue > I've verified via ls -l /dev/disk/by-uuid that my drive where Ubuntu is installed matches the UUID that supposedly doesn't exist. The UUID of my thumb drive when inserted happens to be 06B3-9C68. There is no mention of my USB drive's UUID anywhere in /boot/grub/grub.cfg I've also tried to re-install GRUB after booting into my system, removing the stick, and running grub-install /dev/sda. It still happens, and I cannot boot without the USB drive inserted into the computer. And what really gets my goat is that the boot order of my system is CDROMHard DriveUSB. It's not even reaching the USB to try to boot from it, so why does it matter that it's not there? Edit: Also, I ran grub-config without the stick in followed by another grub-install. Still no go.

  • Developing an analytics's system processing large amounts of data - where to start

    - by Ryan
    Imagine you're writing some sort of Web Analytics system - you're recording raw page hits along with some extra things like tagging cookies etc and then producing stats such as Which pages got most traffic over a time period Which referers sent most traffic Goals completed (goal being a view of a particular page) And more advanced things like which referers sent the most number of vistors who later hit a goal. The naieve way of approaching this would be to throw it in a relational database and run queries over it - but that won't scale. You could pre-calculate everything (have a queue of incoming 'hits' and use to update report tables) - but what if you later change a goal - how could you efficiently re-calculate just the data that would be effected. Obviously this has been done before ;) so any tips on where to start, methods & examples, architecture, technologies etc.

  • Alternative ways to make a battle system in a mobile indie game more fun and engaging

    - by Matt Beckman
    I'm developing an indie game for mobile platforms, and part of the game involves a PvP battle system (where the target player is passive). My vision is simple: the active player can select a weapon/item, then attack/use, and display the calculated outcome. I have a concept for battle modifiers that affect stats to make it more interesting, but I'm not convinced this by itself will add enough of a fun factor. I've received some inspiration from the game engine that powers Modern War/Kingdom Age/Crime City, but I want more control to make it more fun. In those games, you don't have the option to select weapons or use items, and the "battling" screen is simply 3D eye candy. Since this will be an indie game, I won't be spending $$$ on a team of professional 3D artists/animators, so my edge needs to be different. What are some alternatives to expensive eye candy that you or others have used to make a non-3D PvP game more fun and engaging? Did the alternative concepts survive the release?

    In my work, I do requirements gathering, analysis and design of business solutions in addition to coding. There are multiple software systems and packages, and developers are expected to work on any of them, instead of being assigned to make changes to only 1 system or just a few systems. How developers ensure they have captured all of the necessary requirements and resolved any conflicting requirements? An example of this type of scenario: Bob the developer is asked to modify the problem ticket system for a hypothetical utility repair business. They contract with a local utility company to provide this service. The old system provides a mechanism for an external customer to create a ticket indicating a problem with utility service at a particular address. There is a scheduling system and an invoicing system that is dependent on this data. Bob's new project is to modify the ticket placement system to allow for multiple addresses to entered by a landlord or other end customer with multiple properties. The invoicing system bills per ticket, but should be modified to bill per address. What practices would help Bob discover that the invoicing system needs to be changed as well? How might Bob discover what other systems in his company might need to be changed in order to support the new changes\business model? Let's say there is a documented specification for each system involved, but there are many systems and Bob is not familiar with all of them. End of example. We're often in this scenario, and we do have design reviews but management places ultimate responsibility for any defects (business process or software process) on the developer who is doing the design and the work. Some organizations seem to be better at this than others. How do they manage to detect and solve conflicting or incomplete requirements across software systems? We currently have a lot of tribal knowledge and just a few developers who understand the entire business and software chain. This seems highly ineffective and leads to problems at the requirements level.

  • Database Management System do exist?

    - by Bakaburg
    I want to build a database for my no-profit association, and i was planning to do it by myself. But then i realize that really i don't have the time to buid a solid, secure system. So i was thinking, maybe like cms do exist, maybe there are also database management systems. I mean a layer of abstraction over the database that allow you manage data, manage access to data, create widgets with and expand the data. Maybe with a frontend to use this data and a backend to manage it. that is a cms but not based on pages and post but on data! Moreover, i would like some standard solution, because my IT management position ends this year, so i need something that will be easy to use and expand even by someone that is not a developer. So do exist something that fit my need? PS: i would really like some modern and visually pleasant solution, javascritp and ajax heavy and that relies the fewest is possible on server and reloading of the pages.
