• Mootools accordion inside another...

  - by jimbo

  Hi all, This is a funny one... I have created a mootools accordion with tabs, each section appears when clicked. This works fine. Now within the first accordion that shows, I have another accordion that displays more data. This was to keep the area small with the mass of information that is needed on the page. All works fine, the problem come when the information hidden is larger than the area that is worked our for the first tabs accordion, and it wont display. does any-one either understand what i'm trying to say, or have an idea of a fix or workaround? Hope this makes sense!

• Singleton pattern with Web application, Not a good idea!!

  - by Tony

  Hi I found something funny, I notice it by luck while I was debugging other thing. I was applying MCP pattern and I made a singleton controller to be shared among all presentations. Suddenly I figured out that some event is called once at first postback, twice if there is two postback, 100 times if there is 100 postbacks. because Singleton is based on a static variable which hold the instance, and the static variable live across postbacks, and I wired the event assuming that it will be wired once, and rewired for each postback. I think we should think twice before applying a singleton in a web application, or I miss something?? thanks

• Windows service installed successfully but not responding after started.

  - by Ridhi

  I have a windows service written in C#, .Net framework 2.0. I installed it on three machines and it worked fine but on one machine (with .Net framework 2.0) the setup has installed the service successfully but the service is not responding after I start it. I check for this by checking whether a log file is created at a specific path insribed in the config file or not. This log file is created everytime the timer elapses the interval time. I'm unable to figure out the reason. Have checked all the parameters but unable to get any solution to this. The funny thing is that the same setup is running well on other machines. P.S.: I have admin access on all the servers I'm installing this service on.

• .NET applications sometimes doesn’t work on Windows CE

  - by KZChris

  Hi, I write applications for Windowe ME and CE in C# .NET 2.0. Sometimes I’ve got problems because applications don’t work on some navigation devices. On Windowe ME it is not problem because .NET can be installed from a cab, but on most Windows CE devices it is impossible because after soft reset all changes disappear. I found out that in most difficult cases good solution is to put all dll-s belonging to .NET installation cab in the folder where the application runs and everything work well. However there are some devices for example Navroad NR460 (Windows CE 5.0) on which none of .NET applications work (it is funny because previous and next version of that navigation works well). I didn’t found on this device cgacutil.exe program. Is this possible to force the device to run any .NET application without installing the Windows again? What should I try to do to check if running .NET a applications is possible? What conditions should be fulfilled to run easiest application written even in .NET 1.0

• Using php to create a password system with chinese characters

  - by WillDonohoe

  Hi guys, I'm having an issue with validating chinese characters against other chinese characters, for example I'm creating a simple password script which gets data from a database, and gets the user input through get. The issue I'm having is for some reason, even though the characters look exactly the same when you echo them out, my if statement still thinks they are different. I have tried using the htmlentities() function to encode the characters, the password from the database encodes nicely, giving me a working '& #35441;' (I've put a space in it to stop it from converting to a chinese character!). The other user input value gives me a load of funny characters. The only thing which I believe must be breaking it, is it encodes in a different way and therefore the php thinks it's 2 completely different strings. Does anybody have any ideas? Thanks in advance, Will

• javascript call url from different domain

  - by user246114

  Hi, I want to post some data via javascript to another domain. Something like: http://www.othersite.com/submitfunnyname?name=blah The other site (othersite.com) has a REST interface that you can call (well actually this is a get example) to submit a funny name to them. Can I do this already with javascript? I'm a little confused on this - I know if that service wants to return some data, I'd need to use something like JSON-P - even though here I'm submitting some data, I guess the service will return some message structure letting me know the result, so it would have to be JSON-P, right? Thanks

• What's the difference between FireBug's conole.log() and console.debug() ?

  - by 6bytes

  A very simple code to illustrate the difference. var x = [0, 3, 1, 2]; console.debug('debug', x); console.log('log', x); // above display the same result x.splice(1, 2); // below display kind of a different result console.debug('debug', x); console.log('log', x); The javascript value is exactly the same but console.log() displays it a bit differently than before applying splice() method. Because of this I lost quite a few hours as I thought splice is acting funny making my array multidimensional or something. I just want to know why does this work like that. Does anyone know? :)

• "this" in JavaScript

  - by cf_PhillipSenn

  I'm trying to understand the syntax of how to put together a JavaScript function as an object. Q: Is this the right way to do it? The reason why I ask is because I'm looking at it in Firebug and I was hoping to be able to drill down and see the value of myVar and myVariable, but instead Firebug only says that "this" is an object Object. var myObject = { init: function() { var myVar = 1; myObject.myVariable = 2; console.log('"this" when called as an object: ' + this); } } myObject.init(); Also, what's the funny little syntax to call it directly upon declaration? Something about (), but when I remove the last line and put () at the end of the declaration, I get a syntax error.

• PHP export to excel

  - by user1865240

  I'm having a trouble that I can't export japanese texts to excel (xls). I used the following codes: header('Content-type: application/ms-excel;charset=UTF-8'); header('Content-Disposition: attachment; filename='.$filename); header("Pragma: no-cache"); echo $contents; But in the excel file, the text changed to funny characters like this: é™?定ç‰? ã?¨ã??ã?¯ã??ã?£ã?†ã?ªã?¢å??犬ã?®ã?Œæ??ã? ’è??ã??ã?Ÿã?†ã?£ã??ã??ã??ã?? ï??

• Silverlight Firestarter thoughts, and thanks to one and all!

  - by Dave Campbell

  A few metrics that of course got out of hand, but some may find interesting:   1/2 My share of the MVP of the Year award in February of 2009 with Laurent Bugnion 2 Number of degrees I hold: B.S., M.S. Electrical Engineering 3 Number of years in the U.S. Army 3.5 Number of years SilverlighCream has been posted 4 Number of times awarded MVP 6 Number of professional positions I've worked: Antenna Rigger, Boilermaker, Musician, Electronic Technician, Hardware Engineer, Software Engineer 16 Number of companies I've worked for during my career as an Engineer 19 Age at which I turned my first line of code 28 Age at which I hit the workforce as an Engineer 33 Number of years working as an Engineer 43 Number of years writing code 62 Number of years since instantiation 116 Number of tags to search SilverlightCream with 645 Number of blogs I view to find articles (at this moment) 664 Number of articles tagged wp7dev at SilverlightCream right now 700 Number of Twitter followers for WynApse 981 Number of individual bloggers in the SilverlightCream database 1002 Number of SilverlightCream blogposts 1100 Number of people live in Redmond for the Firestarter (I think) 1428 Number of total blogposts at GeeksWithBlogs (not counting this one) 4200 Number of Feedburner subscribers (approximately) 6500 Number of Twitter followers for SilverlightNews (approximately) 7087 Number of posts tagged and aggregated at SilverlightCream right now 13000 Number of people registered to watch the Firestarter online (I think) The overwhelming feeling I have returning from the Silverlight Firestarter: Priceless There is absolutely no way that I could personally thank everyone that over the last few years has held their hand out and offered me a step up to get to the point that Scott Guthrie called me out in his keynote. So I'm just going to hit the highlights here... Scott Guthrie Thanks for not only being the level you are at Microsoft, but for being so approachable, easy to talk to, willing to help everyone, and above all knowledgable. My first level manager at my last position asked if Visual Studio was a graphics program... and you step up to a laptop at a conference and type "File->New Program" ... 'nuff said... oh yeah, thanks for the shoutout! John Papa Thanks for being a good friend, ramroding the Firestarter, being a great guy to be around, and for the poster... holy crap is that cool. Tim Heuer Thanks for all you did as a great DE in Phoenix, and for helping out so many of us, of course being a great guy, and for the poster as well... I think you and John shared that task. In no order at all my buddy Michael Washington, Laurent Bugnion (the other half of the first Silverlight MVP of the Year) Tim Sneath, Mike Harsh, Chad Campbell and Bryant Likes (from back in the day), Adam Kinney, Jesse Liberty, Jeff Paries, Pete Brown, András Velvárt, David Kelly, Michael Palermo, Scott Cate, Erik Mork, and on and on... don't feel bad if your name didn't appear, I have simply too many supporters to name. Silverlight Firestarter Indeed All the people mentioned here, and all the MVPs knew Silverlight was NOT dead, but because of a very unfortunate circumstance, the popular media opinion became that. Consequently the Firestarter exploded from a laid-back event to a global conference. People worked their ass off getting bits ready and presentations using those bits. All to stem the flow of misinformation. All involved please accept my personal thanks for an absolutely awesome job. I had the priviledge of watching the 'prep' on Wednesday afternoon, and was blown away the first time I saw the 3D demo... and have been blown away every time I've seen it since. Not to mention all the other goodness in Silverlight 5. Yes I hit 1000 on my blog, but more importantly, all of you are blogging and using Silverlight, and Microsoft hit one completely out of the park... no... they knocked it out of the neighborhood with the Firestarter. It was amazing to be there for it, and it will be awesome to use the new bits as we get them. Keep reading, there's tons more to come with Silverlight and SilverlightCream following along behind. As usual, this old hacker is humbled to be allowed to play with all the cool kids... Thanks one and all for everything, and Stay in the 'Light

• Java - SAX parser on a XHTML document

  - by Peter

  Hey, I'm trying to write a SAX parser for an XHTML document that I download from the web. At first I was having a problem with the doctype declaration (I found out from here that it was because W3C have intentionally blocked access to the DTD), but I fixed that with: XMLReader reader = parser.getXMLReader(); reader.setFeature("http://apache.org/xml/features/disallow-doctype-decl",true); However, now I'm experiencing a second problem. The SAX parser throws an exception when it reaches some Javascript embedded in the XHTML document: <script type="text/javascript" language="JavaScript"> function checkForm() { answer = true; if (siw && siw.selectingSomething) answer = false; return answer; }// </script> Specifically the parser throws an error once it reaches the &&'s, as it's expecting an entity reference. The exact exception is: `org.xml.sax.SAXParseException: The entity name must immediately follow the '&' in the entity reference. at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:198) at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.fatalError(ErrorHandlerWrapper.java:177) at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:391) at com.sun.org.apache.xerces.internal.impl.XMLScanner.reportFatalError(XMLScanner.java:1390) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanEntityReference(XMLDocumentFragmentScannerImpl.java:1814) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(XMLDocumentFragmentScannerImpl.java:3000) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocumentScannerImpl.java:624) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:486) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:810) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:740) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:110) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1208) at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(SAXParserImpl.java:525) at MLIAParser.readPage(MLIAParser.java:55) at MLIAParser.main(MLIAParser.java:75)` I suspect (but I don't know) that if I hadn't disabled the DTD then I wouldn't get this error. So, how can I avoid the DTD error and avoid the entity reference error? Cheers, Pete

• Eclipse - How can I change a 'Project Facet' from Tomcat 6 to Tomcat 5.5?

  - by pcimring

  (Eclipse 3.4, Ganymede) I have an existing Dynamic Web Application project in Eclipse. When I created the project, I specified 'Default configuration for Apache Tomcat v6' under the 'Configuration' drop down. It's a month or 2 down the line, and I would now like to change the configuration to Tomcat 'v5.5'. (This will be the version of Tomcat on the production server.) I have tried the following steps (without success): I selected Targeted Runtimes under the Project Properties The Tomcat v5.5 option was disabled and The UI displayed this message: If the runtime you want to select is not displayed or is disabled you may need to uninstall one or more of the currently installed project facets. I then clicked on the Uninstall Facets... link. Under the Runtimes tab, only Tomcat 6 displayed. For Dynamic Web Module, I selected version 2.4 in place of 2.5. Under the Runtimes tab, Tomcat 5.5 now displayed. However, the UI now displayed this message: Cannot change version of project facet Dynamic Web Module to 2.4. The Finish button was disabled - so I reached a dead-end. I CAN successfully create a NEW Project with a Tomcat v5.5 configuration. For some reason, though, it will not let me downgrade' an existing Project. As a work-around, I created a new Project and copied the source files from the old Project. Nonetheless, the work-around was fairly painful and somewhat clumsy. Can anyone explain how I can 'downgrade' the Project configuration from 'Tomcat 6' to 'Tomcat 5'? Or perhaps shed some light on why this happened? Thanks Pete

• Filtering documents against a dictionary key in MongoDB

• How do you tune Eclipse IDE? How do you use Eclipse IDE?

  - by Kirzilla

  Hello, I've started to read the book "Code Craft" by Pete Goodliffe. The fourth chapter is about instruments that developer uses during his daily work; this chapter made me to review my work and I've seriously decided to make it easier with fully personalized IDE. Eclipse IDE is what I've started my learning from... I've read documentation and found that it's really easy to do tasks routine from Eclipse. We are using Mantis for tracking tasks and it was great surprise for me to find out Mantis Connector for Mylyn. Also I was pretty glad to see SVN client integrated into Eclipse IDE. Also I've found UML2 tool for Eclipse, but was disappointed because there is no any graphic interface for building diagramms. (Or, maybe, I'm was searching in wrong place?) What useful plugins do you use in your daily work? How do you use Eclipse for collaboration in your team? Do you have any links about intergration Eclipse IDE experience in dev. team? Thank you!

• WordPerfect programmers refusing to use anything but assembler

  - by Totophil

  There is a version (popularised by Joel Spolsky) attributing the demise of WordPerfect to a refusal of its programmers to use anything but assembler that led to delay of the first WPwin release and as result eventually to losing the all important battle with Microsoft. There are a few references to programming work being done using assembler in the autobiographical book "Almost Perfect" by W. E. Pete Peterson who used to have a major influence at running the corporation. But these references go back to early 80's when WordPerfect was trying to gain a significant market share by defeating WordStar and not early nineties when the battle with MS took place. I am looking for a second independent source to confirm the assumption. Maybe someone who worked for WordPerfect Corporation at a time, who was close to the company, or had a chance to see the source could clarify the issue. Your help is much appreciated, thanks! Please note that this question is not about any other theories or reasons behind WordPerfect demise. I really just need to clarify whether they used assembler as a primary language for WPwin and (as a bonus really) whether there were discussions held within the corporation about assembler being the right choice. Concisely: Did WPCorp use assembler as a primary language for WPwin? Were discussions held at a time amongst WP Corp staff about assembler being the right choice (was it management or programmers decision)?

• JUnit Test method with randomized nature

  - by Peter

  Hey, I'm working on a small project for myself at the moment and I'm using it as an opportunity to get acquainted with unit testing and maintaining proper documentation. I have a Deck class with represents a deck of cards (it's very simple and, to be honest, I can be sure that it works without a unit test, but like I said I'm getting used to using unit tests) and it has a shuffle() method which changes the order of the cards in the deck. The implementation is very simple and will certainly work: public void shuffle() { Collections.shuffle(this.cards); } But, how could I implement a unit test for this method. My first thought was to check if the top card of the deck was different after calling shuffle() but there is of course the possibility that it would be the same. My second thought was to check if the entire order of cards has changed, but again they could possibly be in the same order. So, how could I write a test that ensures this method works in all cases? And, in general, how can you unit test methods for which the outcome depends on some randomness? Cheers, Pete

• Join two list comparing their elements properties

  - by 100r

  public class Person() { int ID; string Name; DateTime ChangeDate } var list1 = new List<Person> { new Person { ID= 1, Name = "Peter", ChangeDate= "2011-10-21" }, new Person { ID= 2, Name = "John", ChangeDate= "2011-10-22" }, new Person { ID= 3, Name = "Mike", ChangeDate= "2011-10-23" }, new Person { ID= 4, Name = "Dave", ChangeDate= "2011-10-24" } }; var list2 = new List<Person> { new Person { ID= 1, Name = "Pete", ChangeDate= "2011-10-21" }, new Person { ID= 2, Name = "Johny", ChangeDate= "2011-10-20" }, new Person { ID= 3, Name = "Mikey", ChangeDate= "2011-10-24" }, new Person { ID= 5, Name = "Larry", ChangeDate= "2011-10-27" } }; As output I would like to have list1 + list2 = Person { ID= 1, Name = "Peter", ChangeDate= "2011-10-21" }, Person { ID= 2, Name = "John", ChangeDate= "2011-10-22" }, Person { ID= 3, Name = "Mikey", ChangeDate= "2011-10-24" }, Person { ID= 4, Name = "Dave", ChangeDate= "2011-10-24" } Person { ID= 5, Name = "Larry", ChangeDate= "2011-10-27" } And the Algorithm is like this. Join two list. If elements of lists have same ID, compare them by ChangeDate and take the ond with bigger date. If ChangeDate are equeal take any of them but not both. Maybe its easier to concat both lists and than to filter them with lambda. I tried, but always came out with some ugly code :/ Anyone have any idea?

• Java Constructor Style (Check parameters aren't null)

  - by Peter

  What are the best practices if you have a class which accepts some parameters but none of them are allowed to be null? The following is obvious but the exception is a little unspecific: public class SomeClass { public SomeClass(Object one, Object two) { if (one == null || two == null) { throw new IllegalArgumentException("Parameters can't be null"); } //... } } Here the exceptions let you know which parameter is null, but the constructor is now pretty ugly: public class SomeClass { public SomeClass(Object one, Object two) { if (one == null) { throw new IllegalArgumentException("one can't be null"); } if (two == null) { throw new IllegalArgumentException("two can't be null"); } //... } Here the constructor is neater, but now the constructor code isn't really in the constructor: public class SomeClass { public SomeClass(Object one, Object two) { setOne(one); setTwo(two); } public void setOne(Object one) { if (one == null) { throw new IllegalArgumentException("one can't be null"); } //... } public void setTwo(Object two) { if (two == null) { throw new IllegalArgumentException("two can't be null"); } //... } } Which of these styles is best? Or is there an alternative which is more widely accepted? Cheers, Pete

• python list/dict property best practice

  - by jterrace

  I have a class object that stores some properties that are lists of other objects. Each of the items in the list has an identifier that can be accessed with the id property. I'd like to be able to read and write from these lists but also be able to access a dictionary keyed by their identifier. Let me illustrate with an example: class Child(object): def __init__(self, id, name): self.id = id self.name = name class Teacher(object): def __init__(self, id, name): self.id = id self.name = name class Classroom(object): def __init__(self, children, teachers): self.children = children self.teachers = teachers classroom = Classroom([Child('389','pete')], [Teacher('829','bob')]) This is a silly example, but it illustrates what I'm trying to do. I'd like to be able to interact with the classroom object like this: #access like a list print classroom.children[0] #append like it's a list classroom.children.append(Child('2344','joe')) #delete from like it's a list classroom.children.pop(0) But I'd also like to be able to access it like it's a dictionary, and the dictionary should be automatically updated when I modify the list: #access like a dict print classroom.childrenById['389'] I realize I could just make it a dict, but I want to avoid code like this: classroom.childrendict[child.id] = child I also might have several of these properties, so I don't want to add functions like addChild, which feels very un-pythonic anyway. Is there a way to somehow subclass dict and/or list and provide all of these functions easily with my class's properties? I'd also like to avoid as much code as possible.

• SQL SERVER – Mirroring Configured Without Domain – The server network address TCP://SQLServerName:50

  - by pinaldave

  Regular readers of my blog will be aware of my friend who called me few days ago with very a funny SQL Problem SQL SERVER – SSMS Query Command(s) completed successfully without ANY Results. This time, it did not take long before he called me up with another interesting problem, although the issue he was facing this time was not that interesting and also very specific to him, however, he insisted me to share with all of you. Let us understand his situation at first. My friend is preparing for DBA exam Exam 70-450: PRO: Designing, Optimizing and Maintaining a Database Server Infrastructure using Microsoft SQL Server 2008 and for the same, he was trying to set up replication on his local laptop. He had installed two different instances of SQL Server on his computer and every time when he started the mirroring, it failed with common error message. The server network address “TCP://SQLServer:5023? cannot be reached or does not exist. Check the network address name and that the ports for the local and remote endpoints are operational. (Microsoft SQL Server, Error: 1418) Well, before he contacted me, he searched online and checked my article written on the error in mirroring. However, he tried all the four suggestions, but it did not solve his problem. He called me at a reasonable time of late evening (unlike last time, which was midnight!). I even tried all the seven different suggestions myself, as previously proposed in my article; however, none of them worked. While looking at closely at services, I noticed something very simple. He was running all the instances on ‘Network Services’. In fact, his computer was a stand-alone computer. There was no network at all. Also, there was no domain or any other advance network concepts implemented. I just changed services from ‘Network Services’ to ‘Local System’ as his SQL Server was running on his local system and there were no network services. This prompted to restart the services. As this was not the production server and his development machine, we restarted the services on the laptop (do not restart services on production server without proper planning). After changing the ‘services log on’ account to localsystem, when he attempted to reconfigure the mirroring it worked right away. As usually in production server, proper domains are configured and advance network concepts are implemented I had never faced this type of problem earlier. My friend insisted to post this solution to his situation, wherein there was no domain configured and setting up mirroring was throwing an error. According to him, this is bound to help people, like him, who are preparing for certification using single system.

• Pixel Shader, YUV-RGB Conversion failing

  - by TomTom

  I am tasked with playing back a video hthat comes in in a YUV format as an overlay in a larger game. I am not a specialist in Direct3d, so I am struggling. I managed to get a shader working and am rendering 3 textures (Y, V, U). Sadly I am totally unable to get anything like a decent image. Documentation is also failing me. I am currently loading the different data planes (Y,V,U) in three different textures: m_Textures = new Texture[3]; // Y Plane m_Textures[0] = new Texture(m_Device, w, h, 1, Usage.None, Format.L8, Pool.Managed); // V Plane m_Textures[1] = new Texture(m_Device, w2, h2, 1, Usage.None, Format.L8, Pool.Managed); // U Plane m_Textures[2] = new Texture(m_Device, w2, h2, 1, Usage.None, Format.L8, Pool.Managed); When I am rendering them as R, G and B respectively with the following code: float4 Pixel( float2 texCoord: TEXCOORD0) : COLOR0 { float y = tex2D (ytexture, texCoord); float v = tex2D (vtexture, texCoord); float u = tex2D (utexture, texCoord); //R = Y + 1.140 (V -128) //G = Y - 0.395 (U-128) - 0.581 (V-128) //B = Y + 2.028 (U-128) float r = y; //y + 1.140 * v; float g = v; //y - 0.395 * u - 0.581 * v; float b = u; //y + 2.028 * u; float4 result; result.a = 255; result.r = r; //clamp (r, 0, 255); result.g = g; //clamp (g, 0, 255); result.b = b; //clamp (b, 0, 255); return result; } Then the resulting image is - quite funny. I can see the image, but colors are totally distorted, as it should be. The formula I should apply shows up in the comment of the pixel shader, but when I do it, the resulting image is pretty brutally magenta only. This gets me to the question - when I read out an L8 texture into a float, with float y = tex2D (ytexture, texCoord); what is the range of values? The "origin" values are 1 byte, 0 to 255, and the forum I have assumes this. Naturally I am totally off when the values returned are somehow normalized. My Clamp operation at the end also will fail if for example colors in a pixel shader are normalized 0 to 1. Anyone an idea how that works? Please point me also to documentation - I have not found anything in this regard.

• SQLAuthority News – SafePeak’s SQL Server Performance Contest – Winners

  - by pinaldave

  SafePeak, the unique automated SQL performance acceleration and performance tuning software vendor, announced the winners of their SQL Performance Contest 2011. The contest quite unique: the writer of the best / most interesting and most community liked “performance story” would win an expensive gadget. The judges were the community DBAs that could participating and Like’ing stories and could also win expensive prizes. Robert Pearl SQL MVP, was the contest supervisor. I liked most of the stories and decided then to contact SafePeak and suggested to participate in the give-away and they have gladly accepted the same. The winner of best story is: Jason Brimhall (USA) with a story about a proc with a fair amount of business logic. Congratulations Jason! The 3 participants won the second prize of $100 gift card on amazon.com are: Michael Corey (USA), Hakim Ali (USA) and Alex Bernal (USA). And 5 participants won a printed copy of a book of mine (Book Reviews of SQL Wait Stats Joes 2 Pros: SQL Performance Tuning Techniques Using Wait Statistics, Types & Queues) are: Patrick Kansa (USA), Wagner Bianchi (USA), Riyas.V.K (India), Farzana Patwa (USA) and Wagner Crivelini (Brazil). The winners are welcome to send safepeak their mail address to receive the prizes (to “info ‘at’ safepeak.com”). Also SafePeak team asked me to welcome you all to continue sending stories, simply because they (and we all) like to read interesting stuff) as well as to send them ideas for future contests. You can do it from here: www.safepeak.com/SQL-Performance-Contest-2011/Submit-Story Congratulations to everybody! I found this very funny video about SafePeak: It looks like someone (maybe the vendor) played with video’s once and created this non-commercial like video: SafePeak dynamic caching is an immediate plug-n-play performance acceleration and scalability solution for cloud, hosted and business SQL server applications. By caching in memory result sets of queries and stored procedures, while keeping all those cache correct and up to date using unique patent pending technology, SafePeak can fix SQL performance problems and bottlenecks of most applications – most importantly: without actual code changes. By the way, I checked their website prior this contest announcement and noticed that they are running these days a special end year promotion giving between 30% to 45% discounts. Since the installation is quick and full testing can be done within couple of days – those have the need (performance problems) and have budget leftovers: I suggest you hurry. A free fully functional trial is here: www.safepeak.com/download, while those that want to start with a quote should ping here www.safepeak.com/quote. Good luck!

• SQLAuthority News – MS Access Database is the Way to Go – April 1st Humor

  - by pinaldave

  First of all, today is April 1- April Fool’s Day, so I have written this post for some light entertainment. My friend has just sent me an email about why a person should go for Access Database. For a short background, I used to be an MS Access user once (I will not call myself MS Access DBA), and I must say I had a good time with Database at that time. As time passed by, I moved from MS Access to SQL Server. Well, as for my friend’s email, his reasons considering MS Access usage really made me laugh. MS Access may have a few points where it totally makes sense to use it. However, in the email that I received, there was not a single reason which was valid.  In fact, I thought it is an April 1st joke- just delivered a little earlier. Let us see some of the reasons from that email. Thanks to Mahesh Bhesania for sending this email to me. MS Access comes with lots of free stuff, e.g. MS Excel MS Access is the most preferred desktop database system MS Access can import data from MS Excel and SQL Server MS Access provides a real time database MS Access has a free IDE-to-VB Script MS Access fits well in your hard drive I actually think that the above points are either incorrect beliefs of some users, or someone just wrote them to give some laughter with such inaccurate data. And, for the same reason I decided to browse the Internet and do some research on MS Access database to verify my thoughts. While searching on this subject, I found the following two interesting statements from the site: Microsoft Access Database, Why Choose It? Other software manufacturers are more likely to provide interfaces to MS Access than any other desktop database system Microsoft Access consulting rates are typically lower for Access consultants compared to Oracle or SQL Server consultants The second one is may be the worst reason for you to switch to MS Access if you are already an SQL Server consultant. With this cartoon, have you ever felt like you were one of these chickens at some point in time? I guess that the moment might have just happened before the minute we say “I guess we were on the same page?” Does this mean we are IN the same table, or ON the same table?! (I accept bad joke!) It is All Fools’ Day after all, so just laugh! If you have something funny but non-offensive to share, just  leave your comment here.

• SQL Server Scripts I Use

  - by Bill Graziano

  When I get to a new client I usually find myself using the same set of scripts for maintenance and troubleshooting.  These are all drop in solutions for various maintenance issues. Reindexing.  I use Michelle Ufford’s (SQLFool) re-indexing script.  I like that it has a throttle and only re-indexes when needed.  She also has a variety of other interesting scripts on her blog too. Server Activity.  Adam Machanic is up to version 10 of sp_WhoIsActive.  It’s a great replacement for the sp_who* stored procedures and does so much more.  If a server is acting funny this is one of the first tools I use. Backups.  Tara Kizer has a great little T-SQL script for SQL Server backups.  Wait Stats.  Paul Randal has a great script to display wait stats.  The biggest benefit for me is that his script filters out at least three dozen wait stats that I just don’t care about (for example LAZYWRITER_SLEEP). Update Statistics.  I didn’t find anything I liked so I wrote a simple script to update stats myself.  The big need for me was that it had to run inside a time window and update the oldest statistics first.  Is there a better one? Diagnostic Queries.  Glenn Berry has a huge collection of DMV queries available.  He also just highlighted five of them including two I really like dealing with unused indexes and suggested indexes. Single Use Query Plans.  Kim Tripp has a script that counts the number of single-use query plans.  This should guide you in whether to enable the Optimize for Adhoc Workloads option in SQL Server 2008. Granting Permissions to Developers.  This is one of those scripts I didn’t even know I needed until I needed it.  Kendra Little wrote it to grant a login read-only permission to all the databases.  It also grants view server state and a few other handy permissions.   What else do you use?  What should I add to my list?

• A Small Utility to Delete Files recursively by Date

  - by Rick Strahl

  It's funny, but for me the following seems to be a recurring theme: Every few months or years I end up with a host of files on my server that need pruning selectively and often under program control. Today I realized that my SQL Server logs on my server were really piling up and nearly ran my backup drive out of drive space. So occasionally I need to check on that server drive and clean out files. Now with a bit of work this can be done with PowerShell or even a complicated DOS batch file, but heck, to me it's always easier to just create a small Console application that handles this sort of thing with a full command line parser and a few extra options, plus in the end I end up with code that I can actually modify and add features to as is invariably the case. No more searching for a script each time :-) So for my typical copy needs the requirements are: Need to recursively delete files Need to be able to specify a filespec (ie. *.bak) Be able to specify a cut off date before which to delete files And it'd be nice to have an option to send files to the Recycle bin just in case for operator error :-)(and yes that came in handy as I blew away my entire database backup folder by accident - oops!) The end result is a small Console file copy utility that I popped up on Github: https://github.com/RickStrahl/DeleteFiles The source code is up there along with the binary file you can just run. Creating DeleteFiles It's pretty easy to create a simple utility like DeleteFiles of course, so I'm not going to spend any talking about how it works. You can check it out in the repository or download and compile it. The nice thing about using a full programming language like C over something like PowerShell or batch file is that you can make short work of the recursive tree walking that's required to make this work. There's very little code, but there's also a very small, self-contained command line parser in there that might be useful that can be plugged into any project - I've been using it quite a bit for just about any Console application I've been building. If you're like me and don't have the patience or the persistence (that funky syntax requires some 'sticking with it' that I simply can't get over) to get into Powershell coding, having an executable file that I can just copy around or keep in my Utility directory is the only way I'll ever get to reuse this functionality without going on a wild search each time :-) Anyway, hope some of you might find this useful. © Rick Strahl, West Wind Technologies, 2005-2012Posted in Windows  CSharp   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();
