• Verify p2p node

  - by mazzzzz

  Hey guys, I have been working on a p2p namespace for some of my programs. I created a system to encrypt/decrypt the packets send/received with the class. I was using the basic public private key system: 1) encrypt the data with Symmetric encryption 2) encrypt the symmetric key with RSA. Then do the opposite when you decrypted.. I was wondering though, how would you verify if the packet was coming from where it said it was. I was going to use a basic certificate system (where you encrypt with your private RSA key, then they decrypt it with your public key), but I don't know how to do this with C#. I am using the RSACryptoServiceProvider class. Does anyone know how do this? Thanks, Max

• What are your tricks for optimizing your Subversion configuration?

  - by Scott Markwell

  For a Linux or Windows system, what tricks do you do to optimize your Subversion server? The following are my current tricks for a Linux system serving over Apache with HTTPS and backed by Active Directory using LDAP authentication. Enabling KeepAlive on Apache Disable SVNPathAuthz Increase LDAP Cache Using the FSFS storage method instead of BDB Feel free to call this into question. I don't have hard proof that FSFS out performs BDB, only lots of tribal knowledge and hearsay.

• Choosing between assembler and COBOL

  - by Azares Cob

  I have to rewrite and greatly modify parts of a legacy COBOL application. The COBOL source-code is available (around 100.000 lines of copy & pasted code mixed with GOTOs). Some more details on the system: It is a general management system controlling transactions, bank management, customer data and employees of the company I work for. The COBOL-powered database is about 4 Terabytes distributed over 50 old HDDs. (But messing around with them is the sysadmins job) They are using COBOL85 only. Now I have two options: Rewrite and refactor 50% of the old COBOL system, or use X86 assembly. Should I use X86 assembler or COBOL?

• Calling C# from ColdFusion

  - by stomcavage

  I've written a .dll in C# to change the permissions on a folder. I also wrote an .exe to test the .dll and it successfully changes the permissions. Now I'm trying to call the .dll from ColdFusion, but I'm getting an error about System/Security/IPermission not being found. I'm assuming this is an interface in C# that ColdFusion can't find in any of the available assemblies on my system. I've added the System.Security assembly to my References in the C# project. Is there something else I need to do to make sure ColdFusion can find the interface? Here's how I'm using the .dll: <cfobject type="dotnet" name="permObj" assembly="#pathToDLLs#CoursePortal.dll" class="CoursePortal.Permissions"> <cfset permObj.revokePermissions(dir, username)>

• Changing Java from OpenJDK to SunJava

  - by SpiXel

  I want to change OpenJDK to SunJava in my ubuntu linux desktop , i have downloaded the "jdk-7.tar.gz" from sun's website, but there problem is how to make the system to use the newly downloaded java ? I tried adding the new jdk/bin/java to my PATH ( from .bashrc ) but that seem not to work (cause probably OpenJDK's path is inside my PATH variable as well , so the system checks that first) Here's my JDK7 : /usr/lib/jdk7/bin/java Here's what $(which java) outputs : /usr/bin/java Thanks in advance

• Can I serialize a BitArray to XML?

  - by SimonNet

  Hello I have a business class which I need to serialize to xml. It has a BitArray property. I have decorated it with [XmlAttribute] but the serialization is failing with To be XML serializable, types which inherit from ICollection must have an implementation of Add(System.Boolean) at all levels of their inheritance hierarchy. System.Collections.BitArray does not implement Add(System.Boolean). I am not sure whether its possible to serialize to xml? If not what would be an efficient means of serializing the BitArray Thanks for looking

• Is there anything like memcached, but for sorted lists?

  - by depesz

  I have a situation where I could really benefit from having system like memcached, but with the ability to store (per each key) sorted list of elements, and modifying the list by addition of values. For example: something.add_to_sorted_list( 'topics_list_sorted_by_title', 1234, 'some_title') something.add_to_sorted_list( 'topics_list_sorted_by_title', 5436, 'zzz') something.add_to_sorted_list( 'topics_list_sorted_by_title', 5623, 'aaa') Which I then could use like this: something.get_list_size( 'topics_list_sorted_by_title' ) // returns 3 something.get_list_elements( 'topics_list_sorted_by_title', 1, 10 ) // returns: 5623, 1234, 5436 Required system would allow me to easily get items count in every array, and fetch any number of values from the array, with the assumption that the values are sorted using attached value. I hope that the description is clear. And the question is relatively simple: is there any such system?

• Path with no slash after drive letter and colon - what does it point to?

  - by ya23

  I have mistyped a path and instead of c:\foo.txt wrote c:foo.txt. I expected it to either fail or to resolve to c:\foo.txt, but instead it seems to be resolved to foo.txt in a current user's home folder. Powershell returns: PS C:\> [System.IO.Path]::GetFullPath("c:\foo.txt") c:\foo.txt PS C:\> [System.IO.Path]::GetFullPath("c:foo.txt") C:\Users\Administrator\foo.txt PS C:\> [System.IO.Path]::GetFullPath("g:foo.txt") G:\foo.txt Running explorer.exe from commandline and passing it any of the above results in C:\Users\Administrator\Documents to be opened. I haven't found any documentation of that and I'm utterly confused, please explain the behaviour.

• How to validate Windows VC++ DLL on Unix systems

  - by Guildencrantz

  I have a solution, mostly C#, but with a few VC++ projects, that is pushed through our standard release process (perl and bash scripts on Unix boxes). Currently the initiative is to validate DLL and EXE versions as they pass through the process. All the versioning is set so that File Version is of the format $Id: $ (between the colon and the second dollar should be a git commit hash), and the Product Version is of the format $Hudson Build: $ (between the colon and the second dollar should be a string representing the hudson build details). Currently this system works extremely well for the C# projects because this version information is stored as plain strings within the compiled code (you can literally use the unix strings command and see the version information); the problem is that the VC++ projects do not expose this information as strings (I have used a windows system to verify that the version information is correctly being set), so I'm not sure how to extract the version on a unix system. Any suggestions for either A) Getting a string representation of the version embedded in the compiled code, or B) A utility/script which can extract this information?

• Collectable<T> serialization, Root Namespaces on T in .xml files.

  - by Stacey

  I have a Repository Class with the following method... public T Single<T>(Predicate<T> expression) { using (var list = (Models.Collectable<T>)System.Xml.Serializer.Deserialize(typeof(Models.Collectable<T>), FileName)) { return list.Find(expression); } } Where Collectable is defined.. [Serializable] public class Collectable<T> : List<T>, IDisposable { public Collectable() { } public void Dispose() { } } And an Item that uses it is defined.. [Serializable] [System.Xml.Serialization.XmlRoot("Titles")] public partial class Titles : Collectable<Title> { } The problem is when I call the method, it expects "Collectable" to be the XmlRoot, but the XmlRoot is "Titles" (all of object Title). I have several classes that are collected in .xml files like this, but it seems pointless to rewrite the basic methods for loading each up when the generic accessors do it - but how can I enforce the proper root name for each file without hard coding methods for each one? The [System.Xml.Serialization.XmlRoot] seems to be ignored.

• "Dynamic" localized display of custom DateTimePicker format

  - by S.C. Madsen

  I have a Winform application with 2 DateTimePicker's on it, initialized as follows: private void InitializeComponent() { ... this._StartDate.Format = System.Windows.Forms.DateTimePickerFormat.Short; .... this._StartTime.CustomFormat = System.Globalization.DateTimeFormatInfo.CurrentInfo.ShortTimePattern; this._StartTime.Format = System.Windows.Forms.DateTimePickerFormat.Custom; ... } My question is: When I pick a new region from "Regional and Language Options" in the Control Panel, the _StartDate display is updated to reflect the new regional settings, but the _StartTime is not.

• Sequence diagram example

  The use case to model is the register of a new appointment. The user logins in the system as a patient (role). To make an appointment shoudl enter medical specialty and date. System shoudl look for the doctors availables for that specialty on that date. From the results patient should choose one and then system save the appointment. At the end user shoudl receive an email with the information of the appointment. The classes that I have in my model are: User PAtient Doctor Appointment DoctorShcedule and some more but I think these ones will be involve. I have this initial sequnce diagram: I have problem to set the return messages and also with the email step. Thanks

• BigInteger.Parse() on hexadecimal number gives negative numbers.

  - by brickner

  I've started using .NET 4 System.Numerics.BigInteger Structure and I've encountered a problem. I'm trying to parse a string that contains a hexadecimal number with no sign (positive). I'm getting a negative number. For example, I do the following two asserts: Assert.IsTrue(System.Int64.Parse("8", NumberStyles.HexNumber, CultureInfo.InvariantCulture) > 0, "Int64"); Assert.IsTrue(System.Numerics.BigInteger.Parse("8", NumberStyles.HexNumber, CultureInfo.InvariantCulture) > 0, "BigInteger"); The first assert succeeds, the second assert fails. I actually get -8 instead of 8 in the BigInteger. The problem seems to be when I'm the hexadecimal starts with 1 bit and not 0 bit (a digit between 8 and F inclusive). If I add a leading 0, everything works perfectly. Is that a bad usage on my part? Is it a bug in BigInteger?

• How to run shell script with live feedback from PHP?

  - by Highway of Life

  How would I execute a shell script from PHP while giving constant/live feedback to the browser? I understand from the system function documentation: The system() call also tries to automatically flush the web server's output buffer after each line of output if PHP is running as a server module. I'm not clear on what they mean by running it as a 'server module'. I attempted to run the script in the cgi-bin, but either I'm doing it wrong, or that's not what they mean. Example PHP code: <?php system('/var/lib/script_test.sh'); Example shell code: #!/bin/bash echo "Start..." for i in {1..10} do echo "$i..." sleep 1 done echo "Done."

• Using PowerShell class to invoke a "[namespace.class]::method" style command

  - by Marco

  Hello, I created a powershell object via .net to invoke commands. When I invoke normal commands like 'Get-Process' I had no problems: ps.AddCommand("Get-Process").AddParameter(...).Invoke() but I'm not able to invoke a .net method with the syntax "[namespace.class]::method", just to make an example to invoke [System.IO.File]::Exists("c:\boo.txt"). I tried with ps.AddCommand("[System.IO.File]::Exists(\"c:\\boo.txt\")").Invoke() ps.AddCommand("[System.IO.File]::Exists").AddArgument("c:\\boo.txt").Invoke() and some others. It always throws an exception which says that the command specified is not recognized. There is a way to invoke that type of command? Thanks

• Global variable not stable after platform changed.

  - by user350555

  Our embedded system is built on a hw/sw platform made by enea. After the platform updated recently, we found some operations on the global variable keep crashing the system. For example, we have a global map structure holding some data. We can insert/iterate the map once or twice, then the address of the elements in the map suddenly changed to some forbidden addresses like 0x0 or 0x1d, the system just crash. The only different before/after the platform update is : 1) sw part: It's a c++ software and We changed the compiler from diab cc to gcc. 2) hw part: we have a new board, but the cpu is still powerpc405s. I tried every possible way but still can't figure out the reason. Any thoughts?

• I'm trying to implement 2 factor authentication on the cheap. How would I do that?

  - by Biff MaGriff

  Ok so I need 2 of the 3. Something the user knows. Something the user has. Something the user is. I have a system that is exposed to the internet and we need clients to connect in a secure manner to satisfy our security standards. I'm thinking when a user registers to use our system we send them an application that they install on their home system. The application generates a key based on a timed randomness algorithm. Our application server has the same algorithm so when the user submits their credentials with the key we know that they are a legitimate user. Is this a valid method of 2 factor authentication? What is another way of doing this? Are there any pitfalls that I should be aware of? Thanks for your help!
