• MightyMintyBoost Is a 3-in-1 Gadget Charger

  - by ETC

  If you’re looking for a versatile battery booster, this DIY 3-in-1 solar/usb/wall current charger known as the MightyMintyBoost will top of your phone, mp3 player, and other gadgets with ease. Instructables user Honus didn’t just build the MightMintyBoost to geek out and show off his electronics project skills (although it’s certainly a nifty little project to do so), he’s serious about solar power and the impact clean energy has: Apple has sold over 30 million iPodTouch/iPhone units- imagine charging all of them via solar power…. If every iPhone/iPodTouch sold was fully charged every day (averaging the battery capacity) via solar power instead of fossil fuel power we would save approximately 50.644gWh of energy, roughly equivalent to 75,965,625 lbs. of CO2 in the atmosphere per year. Granted that’s a best case scenario (assuming you can get enough sunlight per day and approximately 1.5 lbs. CO2 produced per kWh used.) Of course, that doesn’t even figure in all the other iPods, cell phones, PDAs, microcontrollers (I use it to power my Arduino projects) and other USB devices that can be powered by this charger- one little solar cell charger may not seem like it can make a difference but add all those millions of devices together and that’s a lot of energy! His MightyMintyBoost is a battery booster for devices that can charge via USB and it accepts incoming current from the solar panel on top (or, on cloudy days can be charged via a wall charger or the USB port on your computer). Hit up the link below to see his full build guide and create your own MightyMintyBoost.

• Architecture- Tracking lead origin when data is submitted by a server

  - by Kevin

  I'm looking for some assistance in determining the least complex strategy for tracking leads on an affiliate's website. The idea is to make the affiliate's integration with my application as easy as possible. I've run into theoretical barriers, so i'm here to explore other options. Application Overview: This is a lead aggregation / distribution platform. We will be focusing on the affiliate portion of this website. Essentially affiliates sign up, enter in marketing campaigns and sell us their conversions. Problem to be solved: We want to track a lead's origin and other events on the affiliate site. We want to know what pages, ads, and forms they viewed before they converted. This can easily be solved with pixel tracking. Very straightforward. Theoretical Issues: I thought I would ask affiliates to place the pixel where I could log impressions and set a third party cookie when the pixel is first called. Then I could associate future impressions with this cookie. The problem is that when the visitor converts on the affiliate's site and I receive their information via HTTP POST from the Affiliate's server I wouldn't be able to access the cookie and associate it with the lead record unless the lead lands on my processor via a redirect and is then redirected back to the affiliate's landing page. I don't want to force the affiliates to submit their forms directly to my tracking site, so allowing them to make an HTTP POST from their server side form processor would be ideal. I've considered writing JavaScript to set a First Party cookie but this seems to make things more complicated for the affiliate. I also considered having the affiliate submit the lead's data via a conversion pixel. This seems to be the most ideal scenario so far as almost all pixels are as easy as copy/paste. The only complication comes from the conversion pixel- which would submit all of the lead information and the request would come from the visitor's machine so I could access my third party cookie.

• JSR Updates - Multiple JSRs migrate to latest JCP version

  - by Heather VanCura

  As part of the JCP.Next reform effort, many JSRs have migrated to the latest version of the JCP program in the last month.  These JSRs' Spec Leads and Expert Groups are contributing to the strides the JCP has been making to enable greater community transparency, participation and agility to the working of the JSR development through the JCP program. Any other JSR Spec Leads interested in migrating to the latest JCP version, now JCP 2.9, as of 13 November, incorporating the Merged Executive Committee (EC), see the Spec Lead Guide for instructions on migrating to the latest JCP version.  For JCP 2.8 JSRs, you are effectively already operating under JCP 2.9 since there are no longer two ECs.  This is the difference for JCP 2.8 JSRs migrating to JCP 2.9 -- a merged EC.  To make the migration official, just inform your Expert Group on a public channel and email your request to admin at jcp.org.

• Ubuntu 12.04 VPN default route issue when using the UI

  - by Pieter Pabst

  When setting up a VPN connection using the UI (System settings = Network) the VPN connection is used as the default route after connecting to it. How can I avoid this? That is without assigning manual addresses. I want the connection to use DHCP. It should use the eth* interfaces for my default route, like they are used before making the connection. The VPN route should only be used when connecting to addresses in the ppp0 adapters range. If possible using the UI only, not that I'm not used to editing config files... But the point of using Ubuntu for me was the "it just works" concept (which is true for 99% of the time, keep up the good work). I tried setting the "Method" combobox in the "Configure..." dialogue to "Automatic (VPN) addresses only". That doesn't make a difference. (Another thing I noticed; the UI shows my connection as a "Wireless connection" in the list control on the left. Don't know why... it has the right icon, but that's probably something for the bug tracker)

• Recording custom variables to identify individual users with Google Analytics

  - by mrtsherman

  I have been asked by our marketing department to add Google Analytics custom variable tracking to my company's website. As the website uses server side includes, modifications to the tracking tag roll out globally - maintenance is therefore a headache! So, if I add the following code (keeping in mind SSI so every page has the same code): // visitor level tracking, id = 12345 // Record a unique id for each visitor. When they return also track this id _gaq.push(['_setCustomVar', 1, 'id', '12345', 1]); // page level tracking // If the user signs up for our newsletter we set newsletter to true // Each page they subsequently visit should also mark this as true _gaq.push(['_setCustomVar', 1, 'newsletter', 'true', 1]); I don't use GA and the marketing people don't use custom variables, so we don't actually know how or if this will work. Therefore my questions are:- Do I want Page, Session or Visitor level tracking? What happens when the same code is used on every page? Can GA 'overwrite' a setting. For example, if I set newsletter to true on page X and then user navigates to page Y, will the variable also be marked there?

• Slow to sync music files?

  - by pst007x

  I have created a folder in the Ubuntu One sync folder and called it music. I have added various albums and the folder has started to sync. However the files were added back in October and still only the folders have synced and no music files. I tested this service before and added a single music file directly into the Ubuntu One folder (no sub folders) and within a few days it synced, however it seems anything in sub folders seem to stall or take a very long time. My ubuntu One program always says syncing and the progression bar creeps, but still no files synced. I know there are issues with speed but a month and going to sync? I recently tested the same files with Dropbox and it took 9 hours. I have port forwarded the https (443) port both in the software firewall and in my router, I tried disabling both firewalls too, either way it makes no difference. I have also tried both from home and the office on different Ubuntu systems. Is there anything anyone has done to improve this service? I am trying to integrate Ubuntu One service into the office to share project files but the syncing is taking to long. I am using the latest Ubuntu 10.10 (fully updated, fresh install), I love Ubuntu and wish to continue to support it anyway I can, so a solution would be good :-) Any help would be appreciated. Thanks Paul

• Update Manager won't open (error related to pythonverbose)

  - by Mateus Machado Luna

  I'm having an issue with update-manager. Last night, my computer restart suddenly during the update process. Now it won't open and it keep appearing on the notifier with a message warning that an error occurred. The error is the same that is displayed when I try to open it on the terminal: Error in sitecustomize; set PYTHONVERBOSE for traceback: EOFError: EOF read where not expected Traceback (most recent call last): File "/usr/bin/update-manager", line 26, in <module> from __future__ import print_function EOFError: EOF read where not expected I've already seen some questions here, but most of them are related to problems with ppas and the source.list file. This seems to be a bug on update-manager itself. I've already tried to remove it and install again, but the problem persists. I also noted another bug: my source-center doesn't open too. The message for it is similar to the other one: Error in sitecustomize; set PYTHONVERBOSE for traceback: EOFError: EOF read where not expected Traceback (most recent call last): File "/usr/lib/command-not-found", line 5, in <module> from __future__ import absolute_import, print_function EOFError: EOF read where not expected For now I'm using apt-get update && upgrade for updating and the Synaptic for the source management. But I really would like to fix this stuff. Anyone can help? I'm with Ubuntu 12.10, Gnome-remix, 64-bits.

• Character creation using spritesheets

  - by Patrick Developer

  I am currently creating a 2D fighting game and have implemented a system where upon starting a new game, the player is presented with the option to create a custom character. I have a set of string arrays set with values that correspond to hair, headgear, chest, lower body and shoes. When done selecting a variety of items from the lists, a code is generated based off the index of each item (i.e 01123), which is then used to assign the correct Spritesheet to the player character. This has already presented a lot of work as I have had to create quite a few spreadsheets based of possible combinations, but I am now looking at a massive amount of work to implement each variation. I have started to look into setting layers for each item to reduce workload, but I am also looking at having different stances for the character - Depending on the currently equipped weapon - so this may present a lot of work either way. My question is, do I have any alternatives or am I stuck creating masses of Spritesheets to cover all combinations? As a side note, how much impact will assigning layered items have on overall performance?

• Statistical Software Quality Control References

  - by Xodarap

  I'm looking for references about hypothesis testing in software management. For example, we might wonder whether "crunch time" leads to an increase in defect rate - this is a surprisingly difficult thing to do. There are many questions on how to measure quality - this isn't what I'm asking. And there are books like Kan which discuss various quality metrics and their utilities. I'm not asking this either. I want to know how one applies these metrics to make decisions. E.g. suppose we decide to go with critical errors / KLOC. One of the problems we'll have to deal with with that this is not a normally distributed data set (almost all patches have zero critical errors). And further, it's not clear that we really want to examine the difference in means. So what should our alternative hypothesis be? (Note: Based on previous questions, my guess is that I'll get a lot of answers telling me that this is a bad idea. That's fine, but I'd request that it's based on published data, instead of your own experience.)

• (LWJGL) Pixel Unpack Buffer Object is Disabled? (glTextImage2D)

• C++11 Tidbits: access control under SFINAE conditions

  - by Paolo Carlini

  Lately I have been spending quite a bit of time on the SFINAE ("Substitution failure is not an error") features of C++, fixing and tweaking various bits of the GCC implementation. An important missing piece was the implementation of the resolution of DR 1170 which, in a nutshell, mandates that access checking is done as part of the substitution process. Consider: class C { typedef int type; }; template <class T, class = typename T::type> auto f(int) - char; template <class> auto f(...) -> char (&)[2]; static_assert (sizeof(f<C>(0)) == 2, "Ouch"); According to the resolution, the static_assert should not fire, and the snippet should compile successfully. The reason being that the first f overload must be removed from the candidate set because C::type is private to C. On the other hand, before the resolution of DR 1170, the expected behavior was for the first overload to remain in the candidate set, win over the second one, to eventually lead to an access control error (*). GCC mainline (would be 4.8) finally implements the DR, thus benefiting the many modern programming techniques heavily exploiting SFINAE, among which certainly the GNU C++ runtime library itself, which relies on it for the internals of <type_traits> and in several other places. Note that the resolution of the DR is active even in C++98 mode, not just in C++11 mode, because it turned out that the traditional behavior, as implemented in GCC, wasn't fully consistent in all the possible circumstances. (*) In practice, GCC didn't really implement this, the static_assert triggered instead.

• Sync KeePassX with KeePass2

  - by bioShark

  Simply put: In Ubuntu I am using KeePassX and in Windows KeePass2. In am not able to export/import passwords from one to another. I would prefer to use the same database, but I don't really know how. If there is no possibility to sync the 2, can you recommend another password vault, which is able to sync passwords from 2 OS, using a shared DB. Thanks I am using Ubuntu 12.04 and Win 7. Edit: I have noticed that KeePass2 is available in the Software Center, so I have installed it, and I can successfully open my Win7 database. Now I will migrate my KeePassX passwords. I am seeing now a huge difference in the looks. While KeePassX doesn't exactly have Ubuntu like look&feel, it's 100 times more elegant than the interface KeePass2 comes with. Well, maybe that was my initial decision for installing KeePassX on my Ubuntu machine. I can't remember. @fossfreedom, please add your comment as a response, so that I can accept it. Thank for the suggestion

• Minimizing data sent over a webservice call on expensive connection

  - by aceinthehole

  I am working on a system that has many remote laptops all connected to the internet through cellular data connections. The application will synchronize periodically to a central database. The problem is, due to factors outside our control, the cost to move data across the cellular networks are spectacularly expensive. Currently the we are sending a compressed XML file across the wire where it is being processed and various things are done with (mainly stuffing it into a database). My first couple of thoughts were to convert that XML doc to json, just prior to transmission and convert back to XML just after receipt on the other end, and get some extra compression for free without changing much. Another thought was to test various other compression algorithms to determine the smallest one possible. Although, I am not entirely sure how much difference json vs xml would make once it is compressed. I thought that their must be resources available that address this problem from an information theory perspective. Does anyone know of any such resources or suggestions on what direction to go in. This developed on the MS .net stack on windows for reference.

• Convience of mySQL over xml

  - by Bonechilla

  Currently I use XML to store specific information to correctly load a few things such as a list of specfied characters, scenes and music, Once more I use JAXB in combination with standard compression/decompression(ZIP) functionality to store a list of extrenous data. This data is called to add functionality to the character, somewhat like Skills in an RPG. Each skill is seperated into its own XML file with a grandlist which contains the names of each file with their extensions omitted and zipped in folder that gets encrypted. At first using xml was working fine however as the skill list grow i worry about its stability. I was wondering if I should begin storing the data in mySQL. Originally I planned to simply convert everything to JSON over xml but i think possibly mySQL would be a better move. Can anyone inform me of the key difference and pros and cons of each I guess i'm looking for the best way to store the data more conviently and would be easier to operate on. The data is mostly primatives and strings and the only arraylist of values i have i can just concat into a single field and parse later

• Calculating collision force with AfterCollision/NormalImpulse is unreliable when IgnoreCCD = false?

  - by Michael

  I'm using Farseer Physics Engine 3.3.1 in a very simple XNA 4 test game. (Note: I'm also tagging this Box2D, because Farseer is a direct port of Box2D and I will happily accept Box2D answers that solve this problem.) In this game, I'm creating two bodies. The first body is created using BodyFactory.CreateCircle and BodyType.Dynamic. This body can be moved around using the keyboard (which sets Body.LinearVelocity). The second body is created using BodyFactory.CreateRectangle and BodyType.Static. This body is static and never moves. Then I'm using this code to calculate the force of collision when the two bodies collide: staticBody.FixtureList[0].AfterCollision += new AfterCollisionEventHandler(AfterCollision); protected void AfterCollision(Fixture fixtureA, Fixture fixtureB, Contact contact) { float maxImpulse = 0f; for (int i = 0; i < contact.Manifold.PointCount; i++) maxImpulse = Math.Max(maxImpulse, contact.Manifold.Points[i].NormalImpulse); // maxImpulse should contain the force of the collision } This code works great if both of these bodies are set to IgnoreCCD=true. I can calculate the force of collision between them 100% reliably. Perfect. But here's the problem: If I set the bodies to IgnoreCCD=false, that code becomes wildly unpredictable. AfterCollision is called reliably, but for some reason the NormalImpulse is 0 about 75% of the time, so only about one in four collisions is registered. Worse still, the NormalImpulse seems to be zero for completely random reasons. The dynamic body can collide with the static body 10 times in a row in virtually exactly the same way, and only 2 or 3 of the hits will register with a NormalImpulse greater than zero. Setting IgnoreCCD=true on both bodies instantly solves the problem, but then I lose continuous physics detection. Why is this happening and how can I fix it? Here's a link to a simple XNA 4 solution that demonstrates this problem in action: http://www.mediafire.com/?a1w242q9sna54j4

• Android&ndash;Finding your SDK debug certificate MD5 fingerprint using Keytool

  - by Bill Osuch

  I recently upgraded to a new development machine, which means the certificate used to sign my applications during debug changed. Under most circumstances you’ll never notice a difference, but if you’re developing apps using Google’s Maps API you’ll find that your old API key no longer works with the new certificate fingerprint. Google's instructions walk you through retrieving the MD5 fingerprint of your SDK debug certificate - the certificate that you’re probably signing your apps with before publishing, but it doesn't talk much about the Keytool command. The thing to remember is that Keytool is part of Java, not the Android SDK, so you'll never find it searching through your Android and Eclipse directories. Mine is located in C:\Program Files\Java\jdk1.7.0_02\bin so you should find yours somewhere similar. From a command prompt, navigate to this directory and type: keytool -v -list -keystore "C:/Documents and Settings/<user name>/.android/debug.keystore" That’s assuming the path to your debug certificate is in the typical location. If this doesn’t work, you can find out where it’s located in Eclipse by clicking Window –> Preferences –> Android –> Build. There's no need to use the additional commands shown on Google's page. You'll be prompted for a password, just hit enter. The last line shown, Certificate fingerprint, is the key you'll give Google to generate your new Maps API key. Technorati Tags: Android Mapping

• Most efficient way to handle coordinate maps in Java

  - by glowcoder

  I have a rectangular tile-based layout. It's your typical Cartesian system. I would like to have a single class that handles two lookup styles Get me the set of players at position X,Y Get me the position of player with key K My current implementation is this: class CoordinateMap<V> { Map<Long,Set<V>> coords2value; Map<V,Long> value2coords; // convert (int x, int y) to long key - this is tested, works for all values -1bil to +1bil // My map will NOT require more than 1 bil tiles from the origin :) private Long keyFor(int x, int y) { int kx = x + 1000000000; int ky = y + 1000000000; return (long)kx | (long)ky << 32; } // extract the x and y from the keys private int[] coordsFor(long k) { int x = (int)(k & 0xFFFFFFFF) - 1000000000; int y = (int)((k >>> 32) & 0xFFFFFFFF) - 1000000000; return new int[] { x,y }; } } From there, I proceed to have other methods that manipulate or access the two maps accordingly. My question is... is there a better way to do this? Sure, I've tested my class and it works fine. And sure, something inside tells me if I want to reference the data by two different keys, I need two different maps. But I can also bet I'm not the first to run into this scenario. Thanks!

• Roll a DIY Camera Jib for $25

  - by Jason Fitzpatrick

  Video gear is expensive; save your pennies by building a DIY camera jib for smooth camera movement on a budget. Over at Oliva tech they explain just how few parts you need to build their DIY jib: The guys here at the studio mocked up a simple DIY jib that is not only ridiculously inexpensive to piece together, but also very straight forward. The point of this jib was to get a very wide range of motion from top to bottom with only a few feet of 0.75? square tube, 1? angled aluminum, 1/4? nuts and bolts, and nylon washers is all you’ll need to put the jib together. This light weight jib can be used on small portable tripods, but will require a fluid head for panning left and right. Hit up the link below for a detailed parts list and build guide.

• Crawling a Content Folio

  - by Kyle Hatlestad

  Content Folios in WebCenter Content allow you to assemble, track, and access a logical group of documents and/or links.  It allows you to manage them as just a list of items (simple folio) or organized as a hierarchy (advanced folio).  The built-in UI in content server allows you to work with these folios, but publishing them or consuming them externally can be a bit of a challenge.   The folios themselves are actually XML files that contain the structure, attributes, and pointers to the content items.  So to publish this somewhere, such as a Site Studio page, you could perhaps use an XML parser to traverse the structure and create your output.  But XML parsers are not always the easiest or most efficient to use.  In order to more easily crawl and consume a Content Folio, Ed Bryant - Principal Sales Consultant, wrote a component to do just that.  His component adds a service which does all the work for you and returns the folio structure as a simple resultset.  So consuming and publishing that folio on a Site Studio page or in your portal using RIDC is a breeze!  For example, let's take an advanced Content Folio example like this: If we look at the native file, the XML looks like this: But if we access the folio using the new service - http://server/cs/idcplg?IdcService=FOLIO_CRAWL&dDocName=ecm008003&IsPageDebug=1 - this is what the result set looks like (using the IsPageDebug parameter). Given this as the result set, it makes it very easy to consume and repurpose that folio. You can download a copy of the sample component here. Special thanks to Ed for letting me share this component!

• Google authorship verification issue

  - by Fraser

  I'm trying to get my blog content author verified so my face gets into the Google search results. I managed to achieve this a few weeks back - When testing my content in the Google authorship testing tool it reported that I had been verified and I could see my mug in the results. All I had to do was wait a couple of weeks before I started popping up in the search results (I think(?)). However, I seem to have thrown a spanner in the works. I set up Google apps for my domain and merged my old Google+ profile into my google apps account. This seemed to reset my Google+ profile (no biggy, since it was a new profile and only had 1 connection). I re-set up my G+ account and tied it all in to my blog and it's content. I am now seeing some very strange behaviour. If you take a look at one of my blog posts through the snippet testing tool: http://www.google.com/webmasters/tools/richsnippets?url=http%3A%2F%2Fblog.fraser-hart.co.uk%2Fjquery-fullscreen-background-slideshow%2F&html= You will see that it is not recognising me as an author. However, when you enter my profile URL (https://plus.google.com/108765138229426105004) into the "Authorship verification by email" input, you will see that it does in fact recognise it as verified. Now, if you try and verify the same page again, it reverts back to unverified. I thought I may have to just wait it out but this has been over a week now and previously (before I merged my profile) it happened instantaneously. Has anyone experienced this bizarre behaviour before? What is happening here? More importantly, is there anything I can do to resolve it? (Apologies for the long and boring question). Cheers!

• Android threads trouble wrapping my head around design

  - by semajhan

  I am having trouble wrapping my head around game design. On the android platform, I have an activity and set its content view with a custom surface view. The custom surface view acts as my panel and I create instances of all classes and do all the drawing and calculation in there. Question: Should I instead create the instances of other classes in my activity? Now I create a custom thread class that handles the game loop. Question: How do I use this one class in all my activities? Or do I have to create a separate thread each time? In my previous game, I had multiple levels that had to create an instance of the thread class and in the thread class I had to set constructor methods for each separate level and in the loop use a switch statement to check which level it needs to render and update. Sorry if that sounds confusing. I just want to know if the method I am using is inefficient (which it probably is) and how to go about designing it the correct way. I have read many tutorials out there and I am still having lots of trouble with this particular topic. Maybe a link to a some tutorials that explain this? Thanks.

• Where is the line drawn with domain names which include a trademark?

  - by Thomas Clayson

  A search on google for "iphone developer" turns up loads of websites which have "iphone" in them, a trademarked name by Apple. So I'm led to believe that having a domain such as iphonedeveloper.com is ok? Well, you're still using Apple's trademark, but it would be hard to brand yourself otherwise. You're an IPHONE DEVELOPER... right? Well, what if I want to provide a website where users pay to get a list of the best offers from Ebay? I might have a domain like ebaydeals.com (I don't... i'm just speculating!). Now I've heard that places like Ebay are really hot on the trigger and fire out emails to people who register domains like that straight away. But whats the difference? In both cases I'm making money from the trademark, effectively, so is it just down to how lenient the company who owns the trademark is? Or are there rules? Is there a specific "line" you don't cross? Thanks

• Deleting a row from self-referencing table

  - by Jake Rutherford

  Came across this the other day and thought “this would be a great interview question!” I’d created a table with a self-referencing foreign key. The application was calling a stored procedure I’d created to delete a row which caused but of course…a foreign key exception. You may say “why not just use a the cascade delete option?” Good question, easy answer. With a typical foreign key relationship between different tables which would work. However, even SQL Server cannot do a cascade delete of a row on a table with self-referencing foreign key. So, what do you do?…… In my case I re-wrote the stored procedure to take advantage of recursion:   -- recursively deletes a Foo ALTER PROCEDURE [dbo].[usp_DeleteFoo]      @ID int     ,@Debug bit = 0    AS     SET NOCOUNT ON;     BEGIN TRANSACTION     BEGIN TRY         DECLARE @ChildFoos TABLE         (             ID int         )                 DECLARE @ChildFooID int                        INSERT INTO @ChildFoos         SELECT ID FROM Foo WHERE ParentFooID = @ID                 WHILE EXISTS (SELECT ID FROM @ChildFoos)         BEGIN             SELECT TOP 1                 @ChildFooID = ID             FROM                 @ChildFoos                             DELETE FROM @ChildFoos WHERE ID = @ChildFooID                         EXEC usp_DeleteFoo @ChildFooID         END                                    DELETE FROM dbo.[Foo]         WHERE [ID] = @ID                 IF @Debug = 1 PRINT 'DEBUG:usp_DeleteFoo, deleted - ID: ' + CONVERT(VARCHAR, @ID)         COMMIT TRANSACTION     END TRY     BEGIN CATCH         ROLLBACK TRANSACTION         DECLARE @ErrorMessage VARCHAR(4000), @ErrorSeverity INT, @ErrorState INT         SELECT @ErrorMessage = ERROR_MESSAGE(), @ErrorSeverity = ERROR_SEVERITY(), @ErrorState = ERROR_STATE()         IF @ErrorState <= 0 SET @ErrorState = 1         INSERT INTO ErrorLog(ErrorNumber,ErrorSeverity,ErrorState,ErrorProcedure,ErrorLine,ErrorMessage)         VALUES(ERROR_NUMBER(), @ErrorSeverity, @ErrorState, ERROR_PROCEDURE(), ERROR_LINE(), @ErrorMessage)         RAISERROR (@ErrorMessage, @ErrorSeverity, @ErrorState)     END CATCH   This procedure will first determine any rows which have the row we wish to delete as it’s parent. It then simply iterates each child row calling the procedure recursively in order to delete all ancestors before eventually deleting the row we wish to delete.
