  • Tale of an Encrypted SSIS Package in msdb and a Lost Password

    - by Argenis
      Yesterday a Developer at work asked for a copy of an SSIS package in Production so he could work on it (please, dear Reader – withhold judgment on Source Control – I know!). I logged on to the SSIS instance, and when I went to export the package… Oops. I didn’t have that password. The DBA who uploaded the package to Production is long gone; my fellow DBA had no idea either - and the Devs returned a cricket sound when queried. So I posed the obligatory question on #SQLHelp and a bunch of folks jumped in – some to help and some to make fun of me (thanks, @SQLSoldier @crummel4 @maryarcia and @sqljoe). I tried their suggestions to no avail…even ran some queries to see if I could figure out how to extract the package XML from the system tables in msdb:   SELECT CAST(CAST(p.packagedata AS varbinary(max)) AS varchar(max)) FROM msdb.dbo.sysssispackages p WHERE p.name = 'LePackage'   This just returned a bunch of XML with encrypted data on it:  I knew there was a job in SQL Agent scheduled to execute the package, and when I tried to look at details on the job step I got the following: Not very helpful. The password had to be saved somewhere, but where?? All of a sudden I remembered that there was a system table I hadn’t queried yet: SELECT sjs.command FROM msdb.dbo.sysjobs sj JOIN msdb.dbo.sysjobsteps sjs ON sj.job_id = sjs.job_id WHERE sj.name = 'Run LePackage' The result: “Well, that’s really secure”, I thought to myself. Cheers, -Argenis

  • Java issues on OpenVZ Ubuntu 11.04 (.jar/.sh files)

    - by IWillNotChange
    I've had a whole line of messes with java and .jar files. I've tried both OpenJDK (from software installer) and about three repositories for Sun. /Desktop# java -jar -Xmx1024m ss.jar Exception in thread "main" java.awt.HeadlessException at java.awt.GraphicsEnvironment.checkHeadless(GraphicsEnvironment.java:173) at java.awt.Window.<init>(Window.java:476) at java.awt.Frame.<init>(Frame.java:419) at java.awt.Frame.<init>(Frame.java:384) at javax.swing.JFrame.<init>(JFrame.java:174) at org.powerbot.bd.<init>(Unknown Source) at org.powerbot.Boot.main(Unknown Source) Two separate errors: ~/Desktop# ./ss.sh [SEVERE] org.server.Boot: Default heap size of 490m too small, restarting with 768m and about 30 different crashes were it just "aborts" with a huge file dump.

  • throw new exception- C#

    - by Jalpesh P. Vadgama
    This post will be in response to my older post throw vs. throw(ex) best practice and difference- c# comment that I should include throw new exception. What’s wrong with throw new exception: Throw new exception is even worse, It will create a new exception and will erase all the earlier exception data. So it will erase stack trace also.Please go through following code. It’s same earlier post the only difference is throw new exception.   using System; namespace Oops { class Program { static void Main(string[] args) { try { DevideByZero(10); } catch (Exception exception) { throw new Exception (string.Format( "Brand new Exception-Old Message:{0}", exception.Message)); } } public static void DevideByZero(int i) { int j = 0; int k = i/j; Console.WriteLine(k); } } } Now once you run this example. You will get following output as expected. Hope you like it. Stay tuned for more..

  • Disallow all user agents except one using .htaccess?

    - by Kian Mayne
    I've been struggling to get this .htaccess working. The aim is to disallow all user agents besides my app. The app sends a GET request with a user agent of lets say 'AcmeUpdater'. Whenever I try to navigate to any file in the folder, I get a 500 - Internal Server Error. Here are the rules I'm using: <IfModule mod_rewrite.c> Options +FollowSymLinks RewriteEngine on RewriteBase / RewriteCond %{HTTP_USER_AGENT} !^KMUpdaterClient* RewriteRule .* - [F,L] </IfModule> I have updated the .htaccess file as suggested in the answer by Nick, and restarted Apache. After trying a couple of different things, it seems that just the presence of a .htaccess is causing the 500 error. I'm getting nothing in the error logs. The .htaccess file at the document root looks like the following: <IfModule mod_rewrite.c> Options +FollowSymLinks ErrorDocument 404 /index.php?error=404 RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d </IfModule> So I realised that the error logs were in chronological order rather than the reverse chronological I expected (Oops!). The error I'm getting is: </IfModule> without matching <IfModule> section. I removed the </IfModule> and still I get that error. Ideas?

  • Connecting a Samsung Galaxy S3 in Ubuntu 13.04

    - by Squishy
    In 13.04, whenever I connect an Android device, one of three things happens: 1 . It mounts successfully (maybe once out of 3 attempts) 2 . It fails to mount with the following error message: Oops! Something went wrong. Unhandled error message: Unable to open MTP device 3 . This one occasionally happens: Unhandled error message: No such interface `org.gtk.vfs.Mount' on object at path /org/gtk/vfs/mount/1 Regardless of activity (even when successfully mounted) it will continuously spam the following error message: Unable to mount SAMSUNG_Android Unable to open MTP Device '[usb:003,00x]' where x seems to be an arbitrary number below 10 and continues counting up with each new error message until the device is unplugged. I've also just noticed that even if it mounts successfully, it unmounts after about 30 seconds and starts spamming the error message above. The Android device is unlocked, always on and fully charged. ADB seems to function normally. Any suggestions? Further info: this happens on both a stock Samsung S3 and an Xperia Arc S running a custom AOSP based ROM. I've also tried the steps outlined in this Stack Overflow answer, but the problem persists. UPDATE: After doing a dist-upgrade (May 8th 2013), the Xperia Arc S on AOSP ROM now mounts and behaves normally. The S3, however, still behaves as described above. UPDATE: After careful observation, ABD does not, in fact, behave normally. If the error message above appears while sending an app to the device, the attempt is aborted with an error message saying that the device is unavailable.

  • Windows Azure and Server App Fabric &ndash; kinsmen or distant relatives?

    - by kaleidoscope
    Technorati Tags: tinu,windows azure,windows server,app fabric,caching windows azure If you are into Windows Azure then it would be rather demeaning to ask if you are aware of Windows Azure App Fabric. Just in case you are not - Windows Azure App Fabric provides a secure connectivity service by means of which developers can build distributed applications as well as services that work across network and organizational boundaries in the cloud. But some of you may have heard of another similar term floating around forums and blog posts - Windows Server App Fabric. The momentary déjà vu that you might have felt upon encountering it is not unheard of in the Cloud Computing circles - http://social.msdn.microsoft.com/Forums/en/netservices/thread/5ad4bf92-6afb-4ede-b4a8-6c2bcf8f2f3f http://forums.virtualizationtimes.com/session-state-management-using-windows-server-app-fabric Many have fallen prey to this ambiguous nomenclature but its not without a purpose. First announced at PDC 2009, Windows Server AppFabric is a set of application services focused on improving the speed, scale, and management of Web, Composite, and Enterprise applications. Initially codenamed Dublin the app fabric (oops....Windows Server App Fabric) provides add-ons like Monitoring,Tracking and Persistence into your hosted Workflow and Services without the Developer worried about these Functionalities. Alongwith this it also provides Distributed In-Memory caching features from Velocity caching. In short it is a healthy equivalent of Windows Azure App Fabric minus the cloud part. So why bring this up while talking about Windows Azure? Well, apart from their similar last names these powers are soon to be combined if Microsoft's roadmap is to be believed - "Together, Windows Server AppFabric and Windows Azure platform AppFabric provide a comprehensive set of services that help developers rapidly develop new applications spanning Windows Azure and Windows Server, and which also interoperate with other industry platforms such as Java, Ruby, and PHP." One of the most powerful features of the Windows Server App Fabric is its distributed caching mechanism which if appropriately leveraged with the Windows Azure App Fabric could very well mean a revolution in the Session Management techniques for the Azure platform. Well Microsoft, we do have our fingers crossed..... Read on... http://blogs.technet.com/windowsserver/archive/2010/03/01/windows-server-appfabric-beta-2-available.aspx

  • Biggest mistake you've ever made

    - by Rogue Coder
    Similar to the question I read on Server Fault, what is the biggest mistake you've ever made in an IT related position. Some examples from friends: I needed to do some work on a production site so I decided to copy over the live database to the beta site. Pretty standard, but when I went to the beta site it was still pulling out-of-date info. OOPS! I had copied the beta database over to the live site! Thank god for backups. And for me, I created a form for an event that was to be held during a specific time range. Participants would fill out the form for a chance to win, and we would send the event organizers a CSV from the database. I went into the database, and found ONLY 1 ENTRY, MINE. Upon investigating, it appears as though I forgot an auto increment key, and because of the server setup there was no way to recover the lost data. I am aware this question is similar to ones on Stack Overflow but the ones I found seemed to receive generic answers instead of actual stories :) What is the biggest coding error/mistake ever…

  • How to visually "connect" skybox edges with terrain model

    - by David
    I'm working on a simple airplane game where I use skybox cube rendered using disabled depth test. Very close to the bottom side of the skybox is my terrain model. What bothers me is that the terrain is not connected to the skybox bottom. This is not visible while the plane flies low, but as it gets some altitude, the terrain looks smaller because of the perspective. Since the skybox center is always same as the camera position, the skybox moves with the plane, but the terrain goes into the distance. Ok, I think you understand the problem. My question is how to fix it. It's an airplane game so limiting max altitude is not possible. I thought about some way to stretch terrain to always cover whole bottom side of the skybox cube, but that doesn't feel right and I don't even know how would I calculate new terrain dimensions every frame. Here are some screenshot of games where you can clearly see the problem: (oops, I cannot post images yet) darker brown is the skybox bottom here: http://i.stack.imgur.com/iMsAf.png untextured brown is the skybox bottom here: http://i.stack.imgur.com/9oZr7.png

  • Relationship between SOA and OOA

    - by TheSilverBullet
    Thomas Erl defines SOA as follows in his site: Service-oriented computing represents a new generation distributed computing platform. As such, it encompasses many things, including its own design paradigm and design principles, design pattern catalogs, pattern languages, a distinct architectural model, and related concepts, technologies, and frameworks. This definitely sounds like a whole new category which is parallel to object orientation. Almost one in which you would expect an entirely new language to exist for. Like procedural C and object oriented C#. Here is my understanding: In real life, we don't have entirely new language for SOA. And most application which have SOA architecture have an object oriented design underneath it. SOA is a "strategy" to make the entire application/service distributed and reliable. SOA needs OOPS working underneath it. Is this correct? Where does SOA (if at all it does) fit in with object oriented programming practices? Edit: I have learnt through answers that OOA and SOA work with each other and cannot be compared (in a "which is better" way). I have changed the title to "Relationship between SOA and OOA" rather than "comparison".

  • Slightly off topic - How to Fix Sky Go Error [t6013-c1501] (and [t6000-c1501])

    - by bconlon
    Sky doesn't seem to understand what their own errors mean, so I cobbled together an understanding from some other posts and managed to get it working.When you see the error [t6013-c1501] instead of your TV programme in Sky Go, it seems to mean:'You registered a device, but then changed the hardware, so now I'm confused!'In other words, the Digital rights management (DRM) used between Sky Go and Silverlight stored an old fingerprint of your PC, but rather than recognising this and allowing you to remove the device, it just disappears from the 'Manage Devices' page.DISCLAIMER: Perform the following steps at your own risk. It worked for me, but I didn't care if it broke stuff. If you care....don't do it!So, to fix this I did the following:1. Login to Sky Go and click 'Watch live TV' from the home page. It will attempt to show Sky News and fail with the error [t6013-c1501].2. Right click on the error and you should see the Menu option 'Silverlight'. Select this and a dialog should appear. Click the 'Application Storage' tab and delete any entry that relates to sky go. Clcik OK to close the dialog.3. Open explorer and navigate to the folder C:\ProgramData\Microsoft\PlayReady4. Rename the file mspr.hds to mspr.hds.OLD5. Go back to the browser and click F5. You may need to logout/login (not sure).Note: Don't rename/delete the folder C:\ProgramData\Microsoft\PlayReady or you will get the error [t6000-c1501]. The folder must exist in order for the new file to be created by Silverlight. Techie talk:So whoever wrote the code to create a new mspr.hds file didn't write code to check the folder existed causing what I assume is a generic error t6000, probably something like:catch (Exception ex) { WriteToLog("Oops, something broke!"); }#

  • Issue updating domain name servers from BlueHost to AWS

    - by cowls
    I am trying to migrate my site hosting from bluehost to AWS cloud based service. I have the site up and running on AWS with an elastic IP configured, it loads fine when I specify the IP address in the browser. I have gone into Route 53 on the AWS console and created a "hosted zone" for the domain. I then created a new record set of type "A" using the IP address as the value. I have a domain name registered with bluehost. Ive logged into the bluehost account and updated the domain name servers to point to those specified in Route 53 in the AWS console. When I hit the IP address directly the site loads, however it doesn't load when using the domain name (I get a google chrome oops error page saying page is not found) I've tried using this site: http://dns.squish.net/ to debug but it seems to be giving me the correct results. fizaclegems.com 300 IN A 107.20.209.78 Where 107.20.209.78 matches the elastic IP configured in the AWS console. This is the result it gives for all 4 name servers. Am I missing a step here? Does anyone know what else I should be doing or looking for?

  • Managing game objects/components

    - by Xeon06
    Good day everyone, By far the biggest problem that has always dawned on my when programming games is how to structure my code. It just becomes an incredible mess after a while. The reason for that is because I have no idea how different classes should interact with each other. Let's have an example. Say I have a class Player, a class PlayerInput and a class Map. The player class contains information as to the location of the player, whereas the player input class handles changing that location, but by first making sure it's within a walkable area from the map class. How to structure this? My usual approach is to pass those components as parameters in the constructors of the parameters that need them, like so: var map = new Map(); var player = new Player(); var input = new PlayerInput(player, map); The problem with that is that it quickly gets messy, when you add new components you have to go through your constructors and update them, and it doesn't work well if you have mirroring references: var physics = new Physics(input); //Oops, doesn't work var input = new Input(physics); So, how do you guys usually manage this? Thanks.

  • Why won't this Apache modrewrite RewriteRule work?

    - by Jason Rhodes
    I'm trying to get Apache mod rewrite to work on my local machine. I'm running OSX with PHP 5 and the Apache mod rewrite module is enabled. I have a directory called localhost/~Jason/hfh/admin with various PHP includes called based on a $_GET variable. I want to let users type (in theory) localhost/~Jason/hfh/admin/pages and have that URL stay in the address bar, while what gets displayed is localhost/~Jason/hfh/admin/?admin=pages So. I've created a .htaccess file that sits in the /hfh directory. Inside, I've put this mod rewrite text: RewriteEngine On RewriteRule ^admin/([^/.]+)/?$ admin/?admin=$1 [L] When I go to the browser and type localhost/~Jason/hfh/admin/pages I get a "Problem loading page" error, and Firefox says, "Oops. Firefox can't load this page for some reason." Can anyone help me figure this out? I have such a hard time with regex and mod rewrite...

  • Do you have any tips for comments code to keep them in step with the code?

    G'day, I've read both of Steve McConnell's excellent Code Complete books "Code Complete" and "Code Complete 2" and was wondering if people have any other suggestions for commenting code. My commenting mantra could be summed up by the basic idea of expressing "what the code below cannot say". While enjoying this interesting blog post by Jeff about commenting I was still left wondering "When coding, when do you feel a comment is required?" Edit: Oops. Seems to be a duplicate of this question http://stackoverflow.com/questions/121945/how-do-you-like-your-comments so sorry for the noise.

  • Javascript - Concatenate Multiple NodeLists Together

    - by Emtucifor
    I was originally asking for an elegant way to simulate the Array.concat() functionality in IE or older browsers, because it seemed that concat was not supported. Only, of course it is and the reason the object didn't support it is because it wasn't an array. Oops! getElementsByTagName returns a NodeList, not an array. The real question, then, is: what's a good way to get a single list of all the form elements in a document (input, select, textarea, button) to loop through them? An array isn't required... a single NodeList would be perfect, too. Note that I'm using IE6 as this is for a corporate intranet (soon IE8 though).

  • Inheritance Problem in Perl OOP

    - by Sam
    Hello, I have a sub class that calls a method from a super class. and the method in the super class use a method that is defined in the super class as asbstract(not really abstract) but implemented in the sub class. for example: package BaseClass; sub new { } sub method1 { return someAbstractMethod(); } sub someAbtsractMethod { die "oops, this is an abstract method that should be implemented in a subclass" ; } 1; package SubClass; sub new { } sub someAbtsractMethod { print "now we implement the asbtract method"; } 1; now when I do: $sub = new SubClass(); $sub-method1(); It calls the abstract message and i get the specified error message. if I took off the abstractmethod from the super class and just leave the implementation in the subclass, It does not recognize the method and I get subroutine abstractmethod not found error.

Okay, how about @bar.decor? TypeError: unbound method "decor" must be called with a bar instance as first argument (got function instance instead) Ok, how about @self.decor? Name "self" is not defined. Ok, how about @foo.decor?! Name "foo" is not defined. AaaaAAaAaaaarrrrgggg... What am I doing wrong?

  • jQuery Ajax post with dynamic url

    - by morpheous
    I want to send an AJAX POST, but I want the url that the data is sent to, to be derived from the id of the element that was clicked. This is what I have so far: I have written a javascript function (get_my_url) that returns a url, depending on the element id that was passed to the function. The problem is, it is not clear how to bind the function (get_my_url) to the url param of the .ajax() method. jQuery('.elem1').click(function(){ jQuery.ajax({ async: false, type: 'POST', url: get_my_url(jQuery(this).attr('id')), data: 'id1=1', dataType: 'json', success: function(data){ msg = data.msg }, error: function(xrq, status, et){msg='Oops. An error occured!'} }); Does anyone know how to pass a function to the url param?
