• How to handle User Authentication for program in client’s local machine?

  - by Daniel

  Which user authentication scheme could be used at following scenario? 1.Application A developed by my company is installed at user's local computer. 2.Users login at my company's website. 3.If login is successful, access to the application A in user's local machine is granted. The development environment is .NET. Is there a secure way to authenticate the user to access the application? I've thought about encrypting the login information entered at the website, and then sending that information to the program at user's local machine for authentication. but I think as long as the client program has the decrypting ability, it is vulnerabe to decompiling,etc. Thanks in advance!

• Couldn't run loadjava on user schema to load dbwsclientws.jar dbwsclientdb102.jar

  - by padmaja

  I am trying to load oracle webservice client jars to my schema. I did set the PATH to inlcude: /u01/app/oracle/product/10.2.0/db_1/bin When I try to run loadjava as "loadjava -u myschema/myscehmapwd -r -v -f -genmissing dbwsclientws.jar dbwsclientdb102.jar" I am getting error: Exception in thread "main" java.lang.NoClassDefFoundError: oracle/aurora/server/tools/loadjava/LoadJavaMain. Does it mean that jvm is not setup on the box? How can I check if the jvm is enabled or not? I am running it on Oracle 10g in UNIX environment. Any help with the issue is greatly appreciated.

• How do Go web apps function from a server perspective?

  - by Metropolis

  Hey Everyone, I followed the directions on how to create web applications using Go, and I was able to get an application working great. One thing I am confused about though is, when you run the application (./8.out), the terminal will sit there and listen on port 8080 until somebody accesses a page. Does the terminal need to stay up all of the time to run the web application? Does the application act like apache? Does apache need to be run next to this app? Setting this up on a server environment seems very confusing to me right now because I dont understand what the best way to do this is. Thanks for any help on this, Metropolis

• Looking for a wiki-style, standalone, version-control-"safe" documenation package

  - by basszero

  This may sound like it's not a programming related question, but stick with me here... My team and I have found that documenting our project (a development platform w/ API) with a wiki is both useful to us and useful to the users. Due to some organizational issues, we're forced to do multi-site development without network connectivity. We've switched to a DVCS (Mercurial) and had great success with this. The wiki documentation proves to be a problem as the central site is setup with MediaWiki. The offsite people have no way to access or edit the wiki. Is there any sort of wiki-style package which doesn't not require a server/database and will be useable in a DVCS environment? Update: Should be open-source and cross-platform

• How can I obfuscate my Perl script to make it difficult to reverse engineer?

  - by codaddict

  I've developed a Perl script that the a confidential business logic. I have to give this script to another Perl coder to test it in his environment. He will definitely try to extract the logic in my program. So I want to make my script impossible, or at least very very hard, to understand. I've tried a few sites like liraz, but they did not work for me. The encoded Perl script does not work the same as the original one.

• IPSec help on Windows 2003 please!!

  - by roacha

  Hey guys, I am trying to configure IPSec between a web and app server in our environment. I want all traffic between these two servers to use IPsec and be encrypted. These servers are on the same domain so i am currently using Kerebos for security, I have also tried pre-defined keys and nothing changed. When I try and ping between the servers I get "Negotiating IP Security" everytime. I have also confirmed that when I change "Require Security" to "Permit" everything works so IPSec is working, I believe its something with my security setup. Under the security tab both servers have the default 3DES keys first and then DES keys. I have also specified tunnel endpoints (the alternate server's IP). What am I missing? Thanks for any help..

• An easy way to replace fread()'s with reading from a byte array?

  - by Sam Washburn

  I have a piece of code that needs to be run from a restricted environment that doesn't allow stdio (Flash's Alchemy compiler). The code uses standard fopen/fread functions and I need to convert it to read from a char* array. Any ideas on how to best approach this? Does a wrapper exist or some library that would help? Thanks! EDIT: I should also mention that it's reading in structs. Like this: fread(&myStruct, 1, sizeof(myStruct), f);

• Geeting internal Oracle connection from Hibernate in JBoss

  - by espressoshot

  Hello, I need to set an application context through Hibernate. I found there is a method setApplicationContext on oracle.jdbc.internal.OracleConnection. I wrote a test, in which I was getting the Oracle connection from the Hibernate session and it worked fine. However, when I moved the code to my application running under JBoss where connections are obtained from the pool the solution won't work. The error is: $Proxy51 cannot be cast to oracle.jdbc.internal.OracleConnection. (1) How can I get the internal connection in that environment? (2) Is there a better way to set an application context through Hibernate (docs don't say anything about it). Thanks so much. Kris

• Scala Eclipse IDE suddenly ignoring breakpoints

  - by malsmith

  I've been using Scala 2.8RC1 and Scala Eclipse plugin for 2.8 RC1 happily for a few days. However, last night after adding a couple jar files to my environment (apache http client jars) the debugger just stopped stopping at breakpoints in scala code. Java code stops fine at breakpoints. I tried creating a new mimimal scala app breakpoints don't stop. I've tried switching to sun-jre-1.6.0.20 from the openjdk-1.6.18 I had been using. I've switched to the scala 2.8 nightly and also eclipse plugin for scala nightly builds. No luck. I would greatly appreciate ideas for fixes. Rather frustrating as the initial experience with 2.8 was really great.

• PHP code in drupal pages treating > as ?>

  - by AmaDaden

  While working on an existing Drupal site I've noticed a strange glitch that causes any PHP operator with in it to act like a ? tag. This is happening in in Drupal pages that I create that have a 'Input Format' of 'PHP code'. For example this line of code foreach($array as $key = $value){ results in a very broken page that prints out $value){ Does any one know what could be causing this? My Dev environment is XAMPP. Drupal version is 6.15. PHP version is 5.2.9.

• Software automation testing

  - by dotnet-practitioner

  I work in a .net shop where we need to automate software testing. We write ASP.net web apps, web services, windows services, scheduled console application. Back end for all these applications is SQL Server. We would like to automate testing of any bug fixes, any where from web UI change to, middle tier .net code change to sql code change. This tool would be used by programmers to do unit test and played back in different test environments to ensure that bug fix is test correctly in all the environments including the produciton environment. This test would be executed by different teams such as QA, Build, and production site testers. What tool or approach do you recommend?

• Is it safe to develop for older versions of Zend Framework?

  - by RenderIn

  Our vendor-supported server's O/S only supports PHP 5.1.6, which limits us to ZF 1.6. The current version of Zend Framework requires a higher version of PHP. We're struggling to decide whether to adopt ZF because of this incompatibility. Is it feasible to develop (indefinitely) in these older versions of ZF or should we hold off? Features, security, bugs, etc. Is this a path we don't want to go down or are these older versions perfectly usable in a production environment?

• Automating SSRS Report Deployment

  - by MikeTWebb

  Hello....I have a web site in 3 environments (DEV/TEST/PROD). The Web Site uses SSRS which also has 3 different environments(DEV/TEST/PROD). Currently, I am deploying the reports using the Manual Deployment mechanism provided in the SSRS Solution (i.e., right click a report and click "Deploy"). I have to manually change the Deployment URLs for each environment. Is there a way to Automate this so that reports are automatically deployeed to PROD and TEST if a change occurs in DEV? I've seen some info on RSScripter but it looks a little tricky/clunky...I was hoping for a more succinct/streamlined solution. Thanks MikeTWebb

• Know if a Visual Studio Website project is recompiling itself in the background?

  - by jdk

  A number of team members update a central ASP.NET dev site (Website project, not a Web application type). Some kinds of changes cause a recompile/rebuild in it. The large website takes a while to recompile and we've noticed it will still seemingly serve out dynamic pages before everything is internally updated. During the site's "gestation" period, our mileage varies while hitting it. Sometimes we get a correct page, sometimes an compilation error page that will eventually be served up without a compilation error, and at other times an unexpected hybrid. Is it possible to query an ASP.NET website application to see if it's currently compiling or rebuilding itself? If so I would write a status page that the team could reference when they're getting weird behaviour, so they would know to wait. Update: Our team often edit files manually on the dev server. For production we'd make pre-compiled pushes. The dev environment is a little more malleable and ever-changing so I'm looking for a solution to reducing the "confusion" there.

• git, SSH_ASKPASS on windows

  - by Martin Schreiber

  I am writing a graphical git frontend for Linux and Windows (MSEgit) based on MSEide+MSEgui. MSEgit has an internal console window which communicates with git by pipes. On Linux it uses a PTY so SSH asks for key unlocking passwords on the PTY. On Windows I wrote a small password entry application and set the SSH_ASKPASS environment variable accordingly. SSH calls the password application if git is started with CreateProcess() dwCreationFlags DETACHED_PROCESS set but the password entry window will not be focused, its taskbar icon flashes instead. SSH does not run the password application if FreeConsole() is called to be sure that there is no attached console to MSEgit and git is started without DETACHED_PROCESS but CREATE_NO_WINDOW instead. I assume a Windows equivalent of POSIX setsid() should be called. How can I force SSH to use SSH_ASKPASS without the DETACHED_PROCESS flag? If this is not possible, how can I ensure that the password entry window is focused?

• Do you know of a good program for editing/translating resource (.rc) files?

  - by djeidot

  I'm building a C++/MFC program in a multilingual environment. I have one main (national) language and three international languages. Every time I add a feature to the program I have to keep the international languages up-to-date with the national one. The resource editor in Visual Studio is not very helpful because I frequently end up leaving a string, dialog box, etc., untranslated. I wonder if you guys know of a program that can edit resource (.rc) files and Build a file that includes only the strings to be translated and their respective IDs and accepts the same (or similar) file in another language (this would be helpful since usually the translation is done by someone else), or Handle the translations itself, allowing to view the same string in different languages at the same time.

• Suggestions for a good IDE for DB2

  - by ken

  Hi all, I know, I know... it's a horrible fate but I am forced to work in an environment with DB2 on the back end. OK just kidding but the truth is I do like MSSQL's data studio a lot, and well IBM's tool is sorda crummy in my opinion... I was using the free version of Toad but I just got a new 64bit machine which is nice and all but there isn't a free version of Toad that I can find for win7 64. Does anyone have any suggestions for a good IDE to use with DB2? Being a developer I really just do a lot of looking at the DB structure and querying to see what I get back and how I want to get things back etc... Thanks for any advice!

• BlackBerry responseXML is null

  - by Andrew

  I'm trying to port a portion of AJAX code I wrote over to the BlackBerry application's embedded browser. Our base build is 4.6.1 and the RIM documentation claims that XMLHttpRequest's responseXML is available starting with this version. And when I request an XML file from my local server, I get back the responseText (so I know the request is working), but the responseXML is always null. I've made sure the HTTP "Content-Type" header is set to "text/xml" and I am getting the correct data loaded in a web browser. It's just nulling out in the BB web environment. Does anyone know what might be happening? A backup of using the responseText and piping it through DOMParser is not possible because that object was not added to the BB browser until 4.7.1. So I'm not sure what fallback I have.

• PHP - white screen of death!

  - by Industrial

  Hi everyone, After debugging a codeigniter app that were installed into a new development environment, I have started to freak out when seeing white screens with nothing more available. I have been able to solve each and every one of the errors that have caused this, but it have taken seriously way too long time. PHP error_reporting(E_ALL) & display_errors", 1 is set as well. I even installed Xdebug in hope of getting more output, but no. My logging settings are also working, but nothing is written to the log. Is there a way to get something informative printed out instead of a complete white screen? It would certainly shorten my time spent on solving the eventual errors that causes this? Thanks a lot!

• Minimizing Java Thread Context Switching Overhead

  - by binil

  I have a Java application running on Sun 1.6 32-bit VM/Solaris 10 (x86)/Nahelem 8-core(2 threads per core). A specific usecase in the application is to respond to some external message. In my performance test environment, when I prepare and send the response in the same thread that receives the external input, I get about 50 us advantage than when I hand off the message to a separate thread to send the response. I use a ThreadPoolExecutor with a SynchronousQueue to do the handoff. In your experience what is the acceptable delay between scheduling a task to a thread pool and it getting picked up for execution? What ideas had worked for you in the past to try improve this?

• How can I do these operations in C?

  - by Juan Antonio

  Hello, I'm converting some assembly code to C to be able to use it with the current compiler environment I have to work with. I've reached 2 operations I don't know how to translate to C. Anyone know how to do it? In both, offset is an unsigned 32-bit integer and shift is a signed integer value. C_FLAG is a bool. OP1: __asm { __asm mov ecx, shift __asm ror offset, cl } OP2: __asm { __asm bt dword ptr C_FLAG, 0 __asm rcr offset, 1 } Thank you very much for your expertise. P.S.: I'm not the original developer, nor I have seen many x86 assembly code...

• Is `eval`ing in a CPAN module without localizing $@ a bug?

  - by rassie

  I think I've encountered a bug in Params::Validate, but I'm not sure whether I identified the problematic code piece correctly. The code in question failed to pass exceptions up the chain (using Try::Tiny), so I started debugging and found out that a class used inside the try block has a destructor. This destructor calls object methods which use Params::Validate and looking into Validate.pm source I see an eval without $@ localization, i.e. the global $@ gets overwritten. Now I see two options: Params::Validate should always localize $@ and thus it's a bug that should be reported. The bug is in the class in question, because it shouldn't use Params::Validate in a destructor. Params::Validate can stay as it is now. Which one is it? How I should I handle this situation? PS: I think that CPAN modules should be rock-solid and neither break themselves nor their environment, hence the question title.

• VBScript Writing to Server Text File

  - by Keyfer Mathewson

  I have created a VBScript which pulls the service tag, username, and computer name from a computer. What I need to do now is compile this information in a text document. How it's set up is as follows: We have an Active Directory Server, with a folder for login scripts. I have created a batch file to run this .vbs script, and the script works well so far. What I now need is for a file on the AD server, called "logging.txt", to be populated with the information that is created with the .vbs script. This is the script I have so far: 'Get Dell Service Tag Info set ProSet = GetObject("winmgmts:").InstancesOf("Win32_BIOS") Set ProSet1 = GetObject("winmgmts:").InstancesOf("Win32_SystemEnclosure") For each Pro in ProSet For each Pro1 in ProSet1 ServiceTag=Pro.SerialNumber wscript.echo ServiceTag exit for Next exit for Next 'get username and computername, could also be asked in a batch Set oShell = WScript.CreateObject("WScript.Shell") Set oShellEnv = oShell.Environment("Process") sComputerName = oShellEnv("ComputerName") sUsername = oShellEnv("username") wscript.echo sComputerName & " " & sUsername Thank you very much in advance!
