• Ruby On Rails -

  - by Adam S

  I am trying to create a collection_select that is dependent on another collection_select, following the railscasts episode #88.. The database includes a schedule of all cruise ships arrival dates. See attached schema diagram,... (The arrow side of the lines indicate has_many, the non-pointy side indicates belongs_to) In the "booking/new" view I have a collection_select for choosing a cruiseline, then another collection_select will appear for selecting a ship, then another for selecting the date that ship is in. If I ONLY put a collection_select for shipshedule it works fine(because of the direct association with the bookings model). However, if I try to add a collection_select for cruiselines....it breaks(Im assuming because their isnt a direct association). The collection_select for cruiselines returns an undefined method error for "cruiseline_id".....if I simply use "id" the collection_select works, but of course isnt fully functional due to incorrect naming of the form field. I have tried "has_many :shipschedules, :through = :cruiseships" in the cruiseline model and "has_many :bookings, :through = :shipschedules" in the cruiseships model... As you can see in the diagram, I need to access the cruiseships and cruiselines model through the bookings model. I have the models set up so a cruiseline has_many cruiseships, a cruiseship has_many shipschedules, and a shipschedule has_many bookings. But, the bookings model cant directly access the cruiseline model. How do I accomplish this? THANKS!!! http://www.adamstockland.com/common/images/RoRf/PastedGraphic-2.png http://www.adamstockland.com/common/images/RoRf/PastedGraphic-1.png

• Is it best to make fewer calls to the database and output the results in an array?

  - by Jonathan

  I'm trying to create a more succinct way to make hundreds of db calls. Instead of writing the whole query out every time I wanted to output a single field, I tried to port the code into a class that did all the query work. This is the class I have so far: class Listing { /* Connect to the database */ private $mysql; function __construct() { $this->mysql = new mysqli(DB_LOC, DB_USER, DB_PASS, DB) or die('Could not connect'); } function getListingInfo($l_id = "", $category = "", $subcategory = "", $username = "", $status = "active") { $condition = "`status` = '$status'"; if (!empty($l_id)) $condition .= "AND `L_ID` = '$l_id'"; if (!empty($category)) $condition .= "AND `category` = '$category'"; if (!empty($subcategory)) $condition .= "AND `subcategory` = '$subcategory'"; if (!empty($username)) $condition .= "AND `username` = '$username'"; $result = $this->mysql->query("SELECT * FROM listing WHERE $condition") or die('Error fetching values'); $info = $result->fetch_object() or die('Could not create object'); return $info; } } This makes it easy to access any info I want from a single row. $listing = new Listing; echo $listing->getListingInfo('','Books')->title; This outputs the title of the first listing in the category "Books". But if I want to output the price of that listing, I have to make another call to getListingInfo(). This makes another query on the db and again returns only the first row. This is much more succinct than writing the entire query each time, but I feel like I may be calling the db too often. Is there a better way to output the data from my class and still be succinct in accessing it (maybe outputting all the rows to an array and returning the array)? If yes, How?

• look up constants based on value.

  - by PLangeberg

  I have a 3rd party struct that is comprised of the following: [StructLayout(LayoutKind.Sequential, Size=1)] public struct BigBlueReasonCodes { public const int ABC_REASONCODE_DESCRIPTION01 = 1000; public const int ABC_REASONCODE_DESCRIPTION01 = 1005; public const int ABC_REASONCODE_DESCRIPTION01 = 1010; public const int DEF_REASONCODE_DESCRIPTION01 = 2001; public const int DEF_REASONCODE_DESCRIPTION01 = 2010; public const int DEF_REASONCODE_DESCRIPTION01 = 2013; public const int GHI_REASONCODE_DESCRIPTION01 = 3050; public const int GHI_REASONCODE_DESCRIPTION01 = 3051; public const int GHI_REASONCODE_DESCRIPTION01 = 3052; public const string JKL_REASONCODE_DESCRIPTION01 = "XYZ; public const string GHI_REASONCODE_DESCRIPTION01 = "ST"; static BigblueReasonCodes(); } I am trying to look up the reason description(the field name) based on the reason code(the value) so my class can do someting like: string failureReason = GetReasonDescription(reasoncode); Somethings of mention are some have int values and some have string values. I am only worried about the ones with int values. I also only want the ones that start with GHI_ if possible but not a big deal.

• Force the use of interface instead of concrete implementation in declaration (.NET)

  - by gammelgul

  In C++, you can do the following: class base_class { public: virtual void do_something() = 0; }; class derived_class : public base_class { private: virtual void do_something() { std::cout << "do_something() called"; } }; The derived_class overrides the method do_something() and makes it private. The effect is, that the only way to call this method is like this: base_class *object = new derived_class(); object->do_something(); If you declare the object as of type derived_class, you can't call the method because it's private: derived_class *object = new derived_class(); object->do_something(); // --> error C2248: '::derived_class::do_something' : cannot access private member declared in class '::derived_class' I think this is quite nice, because if you create an abstract class that is used as an interface, you can make sure that nobody accidentally declares a field as the concrete type, but always uses the interface class. Since in C# / .NET in general, you aren't allowed to narrow the access from public to private when overriding a method, is there a way to achieve a similar effect here?

• problem by displaying images stored in a MySQL database?

• jQuery validation plugin: valid() does not work with remote validation ?

  - by a-dilla

  I got started by following this awesome tutorial, but wanted to do the validation on on keyup and place my errors somewhere else. The remote validation shows its own error message at the appropriate times, making me think I had it working. But if I ask specifically if a field with remote validation is valid, it says no, actually, its not. In application.js I have this... $("#new_user").validate({ rules: { "user[login]": {required: true, minlength: 3, remote: "/live_validations/check_login"}, }, messages: { "user[login]": {required: " ", minlength: " ", remote: " "}, } }); $("#user_login").keyup(function(){ if($(this).valid()){ $(this).siblings(".feedback").html("0"); }else{ $(this).siblings(".feedback").html("1"); } }) And then this in the rails app... def check_login @user = User.find_by_login(params[:user][:login]) respond_to do |format| format.json { render :json => @user ? "false" : "true" } end end I think that my problem might have everything to do with this ticket over at jQuery, and tried to implement that code, but, being new to jQuery, it's all a bit over my head. When I say bit, I mean way way. Any ideas to fix it, or a new way to look at it, would be a big help.

• Textbox time validations (javascript)

  - by unos

  I have a textbox in which user can enter time (eg- 01:00) and also a drop down box for entering AM/PM fields. (Since the AM/PM field is used, 12-hour time format is used.) The text box allows a max entry of 5 chars only (eg - 01:00). Pls let me know how I can set the 3rd char as a default -colon : , so that the user simply has to enter only the time. How to check if the time entered by the user is numeric or not?. Autocompletion feature : for eg, if user enters 1 then it would automatically be set to 01:00 Javascript Validations for 12-hour format. Eg: if user enters 13:00 then it should change to 01:00 How can I append the text box time values with the am/pm value selected in the drop down box?. Once the values are appended, automatically populate another text box (text box 2) with the result. Eg: 01:00 + pm should be set as 01:00p in the new text box (text box 2). Any help would be appreciated.

• asp.net mvc postback

  - by user266909

  I have a controller with the following two Edit methods. The edit form displays correctly with all additional dropdown lists from the FormViewModel. However, when I changed some field values and submitted the form. None of the changed fields were saved. The fields in the postbask collection have default or null values. I have another edit form which update another table. On submit, the changed values are saved. Does anyone know why? // GET: /Transfers/Edit/5 public ActionResult Edit(int id) { Transfer transfer = myRepository.GetTransfer(id); if (transfer == null) return View("NotFound"); return View(new TransferFormViewModel(transfer)); } // // POST: /Transfers/Edit/5 [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(int id, Transfer collection) { Transfer transfer = vetsRepository.GetTransfer(id); if (transfer == null) return View("NotFound"); else { try { UpdateModel(transfer); vetsRepository.Save(); return RedirectToAction("Details", new { id = transfer.TransfersID }); } catch { ModelState.AddModelErrors(transfer.GetRuleViolations()); return View(new TransferFormViewModel(transfer)); } } }

• Generic list/sublist handling

  - by user628661

  Let's say we have a class class ComplexCls { public int Fld1; public string Fld2; //could be more fields } class Cls { public int SomeField; } and then some code class ComplexClsList: List<ComplexCls>; ComplexClsList myComplexList; // fill myComplexList // same for Cls class ClsList : List<Cls>; ClsList myClsList; We want to populate myClsList from myComplexList, something like (pseudocode): foreach Complexitem in myComplexList { Cls ClsItem = new Cls(); ClsItem.SomeField = ComplexItem.Fld1; } The code to do this is easy and will be put in some method in myClsList. However I'd like to design this as generic as possible, for generic ComplexCls. Note that the exact ComplexCls is known at the moment of using this code, only the algorithm shd be generic. I know it can be done using (direct) reflection but is there other solution? Let me know if the question is not clear enough. (probably isn't). [EDIT] Basically, what I need is this: having myClsList, I need to specify a DataSource (ComplexClsList) and a field from that DataSource (Fld1) that will be used to populate my SomeField

• '??' Not a valid unicode character, but in the unicode character set?

  - by Steve Cotner

  Short story: I can't get an entity like '𠂉' to store in a MySQL database, either by using a text field in a Ruby on Rails app (with default UTF-8 encoding) or by inputting it directly with a MySQL GUI app. As far as I can tell, all Chinese characters and radicals can be entered into the database without problem, but not these rarely typed 'character components.' The character mentioned above is unicode U+20089 and html entity &#131209; I can get it to display on the page by entering <html>&#131209;</html> and removing html escaping, but I would like to store it simply as the unicode character and keep the html escaping in place. There are many other Chinese 'components' (parts of full characters, generally consisting of 2 or 3 strokes) that cause the same problem. According to this page, the character mentioned is in the UTF-8 charset: http://www.fileformat.info/info/unicode/char/20089/charset_support.htm But on the neighboring '...20089/index.htm' page, there's an alert saying it's not a valid unicode character. For reference, that entity can be found in Mac OS X by searching through the character palette (international menu, "Show Character Palette"), searching by radical, and looking under the '?' radical. Apologies if this is too open-ended... can a character like this be stored in a UTF-8-based database? How is this character both supported and unsupported, both present in the character set and not valid?

• BizTalk and IBM WebSphere MQ Errors

  - by Christopher House

  The project I'm currently working on is going to make heavy use of IBM WebShere MQ to send messages from BizTalk to the client's iSeries box.  I'd never previously worked with WebSphere MQ, so I didn't really have any idea what it would take to get this to work.  I was pleasantly surprised that it wasn't too difficult to configure a send port and pass messages through it to a queue.  Or so I thought... A couple of weeks ago, the client gave me the name of a host, queue manager and queue that I'd been using for my development.  Everything was going great, I was able to put messages onto the queue, I was happy, the client was happy.  Life was good.  Then the client tells me that the host I've been connecting to is actually a Solaris box and that in prod, we'll actually be sending to an iSeries.  We both agree that it would behoove us to start pointing my dev environment to their dev iSeries box in order to flush out any weirdness there might be.  As it turns out, it was a good thing we made the change.  As soon as I reconfigured my BRE policy that sets endpoint information to point to the iSeries queue, we started seeing failures in the event log.  An example from the event log: Event Type: Error Event Source: BizTalk Server 2009 Event Category: BizTalk Server 2009 Event ID: 5754 Date:  6/9/2010 Time:  10:16:41 AM User:  N/A Computer: WINDOWS2003 Description: A message sent to adapter "MQSC" on send port "<my dynamic sendport name>" with URI "mqsc://client/tcp/<hostname>(1414)/<queue manager name>/<queue name>" is suspended.  Error details: Failure encountered while attempting to open queue. queue = <queue name> queueManager = <queue manager name>, reasonCode = 6124  MessageId:  {76825C7C-611A-4A56-8A6F-35E1124BDB5C}  InstanceID: {BA389103-DF9B-493F-8C61-44574822AAD6} The key piece of information in the event entry is the reasonCode, 6124.  A quick Google search shows that reasonCode 6124 is the code for MQRC_NOT_CONNECTED.  According to IBM's docs, this means that you've tried to send a message without first opening a connection to the queue manager.  Obviously, in the context of BizTalk, this is an unexpected error, since this sort of thing should be managed entirely by the send adapter. Perusing IBM's documentation a bit more, I came across some info on how to turn on tracing for MQ.  With tracing enabled, I tried sending a message again, then went and reviewed the trace files.  The bulk of the information in the trace files didn't mean a thing to me, but at the end of one of the files, I did notice this: 00006257 15:40:20.327795   3500.4      RSESS:000009 ------{  reqReleaseConn 00006258 15:40:20.328714   3500.4      RSESS:000009 ------}  reqReleaseConn (rc=OK) 00006259 15:40:20.328727   3500.4      RSESS:000009 ------{  xcsClearTraceIdent 0000625A 15:40:20.328739   3500.4           :       ------}  xcsClearTraceIdent (rc=OK) 0000625B 15:40:20.328752   3500.4           :       -----}! trmzstMQCONNX (rc=MQRC_NOT_AUTHORIZED) 0000625C 15:40:20.328765   3500.4           :       ----}! MQCONNX (rc=MQRC_NOT_AUTHORIZED) 0000625D 15:40:20.328766   3500.4           :       ---}! ImqQueueManager::connect (rc=MQRC_NOT_AUTHORIZED) 0000625E 15:40:20.328767   3500.4           :       --}! ImqObject::open (rc=MQRC_NOT_CONNECTED) 0000625F 15:40:20.328768   3500.4           :       --{  ImqQueue::lock 00006260 15:40:20.328769   3500.4           :       --}! ImqQueue::lock (rc=Unknown(1)) 00006261 15:40:20.328769   3500.4           :       --{  ImqQueue::unlock 00006262 15:40:20.328769   3500.4           :       --}! ImqQueue::unlock (rc=Unknown(1)) It seemed like the MQRC_NOT_CONNECTED error was being caused by a security related issue (MQRC_NOT_AUTHORIZED).  I did notice something earlier in the log where it appeared that MQ was passing a field named UID with a value equal to the account name that my BizTalk service was running under.  I ended up creating a new local account on the BizTalk server that had the same name as a user which had access to the queue manager on the iSeries.  I then created a new host instance that ran under this new account, created a send handler for the MQSC adapter on this new host instance and reconfigured my orchestration to run on the new host instance.  After bouncing all my host instances, I was now able to send messages to the iSeries. It's still not clear to me why we were able to connect to the Solaris server.  I ended up contacting IBM's support and they did confirm that the process sending to MQ does in fact pass the identity to the queue manager it's connecting to.

• Create a Customized Tab on the Office 2010 Ribbon

  - by Mysticgeek

  Some MS Office users were put off a bit by the Ribbon feature in 2007 for being cumbersome and confusing. Today we look at a cool new feature in Office 2010 that allows you to create your own custom tabs with specific commands for easier document creation. Create a Customized Tab In our example we’re using Word, but you can create a custom tab in the other Office apps as well. To do so, right-click on the Ribbon and select Customize the Ribbon. The Word Options screen opens up and from here you can manage a lot of customization options. We want to create a new customized tab, so click on the New Tab button.   Now give it a name… Now just drag the commands you want to add from the left column over to your new custom group. You have every command available to choose from. You can select specific groups or all commands from the dropdown menu on the left. That is all there is to it…now you have your own customized tab with the commands you use most often to help you work more efficiently. In this example We didn’t add a whole lot of commands, but you can customize it with as many as you need. You can also create other tabs with different sets of commands too. When you create a customized tab in one application, it’s only going to be in that app. For example if you create on in Word, it’s not going to show in Excel as commands differ between apps. If you want a custom tab in another Office app you’ll need to create one for it. Another very cool thing you can do is export the customizations to use on another machine or pass them to a coworker. To export the customizations, go to the Customize Ribbon section and at the bottom of the right field click Import/Export then Export all customizations. Then save the file to a location on your hard drive.   To import the settings to another machine, go into Ribbon Customizations and select Import customizations file… then browse the the file you exported. You’ll be prompted to confirm you want to import he customizations… After confirming the choice now you’ll see the customization show up on the other machine. This is very handy if you work on several machines throughout the day and want to easily bring your customized tabs with you. If you find yourself using a lot of specific commands throughout the day, creating your own customized tab will help access them more quickly. If you want to test out Office 2010 it’s currently in Public Beta and can be downloaded for free.

• How To Disable Control Panel in Windows 7

  - by Mysticgeek

  If you have a shared computer that your family and friends can access, you might not want them to mess around in the Control Panel, and luckily with a simple tweak you can disable it. Disable Control Panel with Group Policy Note: This process uses Local Group Policy Editor which is not available in Home versions of Windows 7. Skip down below for the registry hack version that works on Home editions as well. First type gpedit.msc into the Search box in the Start menu and hit Enter. When Local Group Policy Editor opens, navigate to User Configuration \ Administrative Templates then select Control Panel in the left Column. In the right column double-click on Prohibit access to the Control Panel. In the next window, select Enable, click OK, then close out of Local Group Policy Editor. After the Control Panel is disabled, you’ll notice it’s no longer listed in the Start Menu. If the user tries to type Control Panel into the Search box in the Start menu, they will get the following message indicating it’s restricted. Disable Control Panel with a Registry Tweak You can also tweak the Registry to disable Control Panel. This will work with all versions of Windows 7, Vista, and XP. Making changes in the Registry is not recommended for beginners and you should create a Restore Point, or backup the Registry before making any changes. Type regedit into the Search box in the Start menu and hit Enter. In Registry Editor navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer. Then right-click in the right pane and create a new DWORD (32-bit) Value. Name the value NoControlPanel. Then right-click on the new Value and click Modify…   In the Value data field change the value to “1” then click OK. Close out of Registry Editor and restart the machine to complete the process. When you get back from reboot, you’ll notice Control Panel is no longer listed in the Start menu. If a user tries to access it by typing Control Panel into the Search box in the Start menu… They will get the following message indicating it is restricted, just like if you were to disable it via Group Policy. If you want to re-enable the Control Panel, go back into the Registry and change the NoControlPanel value back to “0” then reboot the computer. This comes in handy if you have inexperienced users working on your machine and don’t want them messing with Control Panel settings.

• Screen Scraping Twitter

  - by BRADINO

  I got an email today asking for help to scrape Twitter. In particular, to be able to login. So I am going to show everyone, NOT to encourage anyone to violate Twitters terms of use but as an educational blog post about how PHP and cURL can be used to post variables and store cookies. Again, I am using the cScrape class I wrote, which you can download. Step 1 First go to twitter.com and look at the source code of the login to get the form field names and the form post location. You will see that the form posts to https://twitter.com/session and the username and password fields are session[username_or_email] and session[password] respectively. Step 2 Now you are ready to login. So using the fetch function in the Scrape class you create an associative array to contain the form values you want to post. The other thing you will need to do is uncomment the lines for CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR. Cookies will be required to stay logged in and scrape around. The paths to the cookie files need to be writable by your app. Also you will need to uncomment the line about CURLOPT_FOLLOWLOCATION. $data = array('session[username_or_email]' => "bradino", 'session[password]' => "secret"); $scrape->fetch('https://twitter.com/sessions',$data); Step 1.5 Oops that didn't work. All I got back was 403 Forbidden: The server understood the request, but is refusing to fulfill it. Ahhh I see another variable called authenticity_token I bet Twitter was looking for that. So let's back up and first hit twitter.com to get the authenticity_token variable, and then make the login post request with that variable included in our array of parameters. $scrape->fetch('https://twitter.com'); $data = array('session[username_or_email]' => "bradino", 'session[password]' => "secret"); $data['authenticity_token'] = $scrape->fetchBetween('name="authenticity_token" type="hidden" value="','"',$scrape->result); $scrape->fetch('https://twitter.com/sessions',$data); echo $scrape->result; So that's basically it. Now you are logged in and can scrape around and request other pages as you normally would. Sorry it wasn't a longer post. I really do enjoy this kind of stuff so if anyone has a request, hit me up. Errors? 1) Make sure that you are properly parsing the token variable 2) Make sure that you uncommented the lines about CURLOPT_COOKIEFILE and CURLOPT_COOKIEJAR, those options need to be enabled and be sure the path set is writable by your application 3) Make sure that the path to the cookie file is writable and that it is getting data written to it 4) If you get a message about being redirected you need to uncomment the line about CURLOPT_FOLLOWLOCATION, that option needs to be enabled true

• SharePoint.DesignFactory.ContentFiles–building WCM sites

  - by svdoever

  One of the use cases where we use the SharePoint.DesignFactory.ContentFiles tooling is in building SharePoint Publishing (WCM) solutions for SharePoint 2007, SharePoint 2010 and Office365. Publishing solutions are often solutions that have one instance, the publishing site (possibly with subsites), that in most cases need to go through DTAP. If you dissect a publishing site, in most case you have the following findings: The publishing site spans a site collection The branding of the site is specified in the root site, because: Master pages live in the root site (/_catalogs/masterpage) Page layouts live in the root site (/_catalogs/masterpage) The style library lives in the root site ( /Style Library) and contains images, css, javascript, xslt transformations for your CQWP’s, … Preconfigured web parts live in the root site (/_catalogs/wp) The root site and subsites contains a document library called Pages (or your language-specific version of it) containing publishing pages using the page layouts and master pages The site collection contains content types, fields and lists When using the SharePoint.DesignFactory.ContentFiles tooling it is very easy to create, test, package and deploy the artifacts that can be uploaded to the SharePoint content database. This can be done in a fast and simple way without the need to create and deploy WSP packages. If we look at the above list of artifacts we can use SharePoint.DesignFactory.ContentFiles for master pages, page layouts, the style library, web part configurations, and initial publishing pages (these are normally made through the SharePoint web UI). Some artifacts like content types, fields and lists in the above list can NOT be handled by SharePoint.DesignFactory.ContentFiles, because they can’t be uploaded to the SharePoint content database. The good thing is that these artifacts are the artifacts that don’t change that much in the development of a SharePoint Publishing solution. There are however multiple ways to create these artifacts: Use paper script: create them manually in each of the environments based on documentation Automate the creation of the artifacts using (PowerShell) script Develop a WSP package to create these artifacts I’m not a big fan of the third option (see my blog post Thoughts on building deployable and updatable SharePoint solutions). It is a lot of work to create content types, fields and list definitions using all kind of XML files, and it is not allowed to modify these artifacts when in use. I know… SharePoint 2010 has some content type upgrade possibilities, but I think it is just too cumbersome. The first option has the problem that content types and fields get ID’s, and that these ID’s must be used by the metadata on for example page layouts. No problem for SharePoint.DesignFactory.ContentFiles, because it supports deploy-time resolving of these ID’s using PowerShell. For example consider the following metadata definition for the page layout contactpage-wcm.aspx.properties.ps1: Metadata page layout # This script must return a hashtable @{ name=value; ... } of field name-value pairs # for the content file that this script applies to. # On deployment to SharePoint, these values are written as fields in the corresponding list item (if any) # Note that fields must exist; they can be updated but not created or deleted. # This script is called right after the file is deployed to SharePoint.   # You can use the script parameters and arbitrary PowerShell code to interact with SharePoint. # e.g. to calculate properties and values at deployment time.   param([string]$SourcePath, [string]$RelativeUrl, $Context) @{     "ContentTypeId" = $Context.GetContentTypeID('GeneralPage');     "MasterPageDescription" = "Cloud Aviator Contact pagelayout (wcm - don't use)";     "PublishingHidden" = "1";     "PublishingAssociatedContentType" = $Context.GetAssociatedContentTypeInfo('GeneralPage') } The PowerShell functions GetContentTypeID and GetAssociatedContentTypeInfo can at deploy-time resolve the required information from the server we are deploying to. I personally prefer the second option: automate creation through PowerShell, because there are PowerShell scripts available to export content types and fields. An example project structure for a typical SharePoint WCM site looks like: Note that this project uses DualLayout. So if you build Publishing sites using SharePoint, checkout out the completely free SharePoint.DesignFactory.ContentFiles tooling and start flying!

• SQL SERVER – What is a Technology Evangelist?

  - by pinaldave

  When you hear that someone is an “evangelist” the first thing that might pop into your mind is the Christian church.  In fact, the term did come from Christianity, and basically means someone who spreads the news about their faith.  In the technology world, the same definition is true. Technology evangelists are individuals who, professionally or in their spare time, spread the news about the latest new products.  Sounds like a salesperson, right?  No they are absolutely different. Salespeople also keep up to date with a large number of people, and like to convince others to buy their product – and some will go to any lengths to sell!  An evangelist, on the other hand, is brutally honest about the product, even if sometimes it means not making a sale.  An evangelist is out there to tell the TRUTH.  A salesperson needs to make sales. An Evangelist offers a Solution independent of Technology used – a Salesperson offers Particular Technology. With this definition in mind, you can probably think of a few technology evangelists you already know.  Maybe it’s a relative or a neighbor, someone who loves keeping up with the latest trends and is always willing to tell you about them if you ask even the simplest question.  And, in fact, they probably are evangelists and don’t even know it.  For a long time, the work of technology evangelism was in the hands of community and community technology leaders. Luckily now various organizations have understood the importance of the community and helping community to reach their goals. This has lead them to create role of “Technology Evangelists”. Let me talk about one of the most famous Evangelist of the SQL Server technology. Technology Evangelist only belongs to technology and above any country, race, location or any other thing. They are dedicated to the technology. Vinod Kumar is such a man, who have given a lot to community. For years he was a Technology Evangelist for Microsoft, and maintained a blog that was dedicated to spreading his enthusiasm for his favorite products.  He is one of the most respected Evangelists in the field, and has done a lot of work to define the job for other professionals. Vinod’s career has since progressed to the Microsoft Technology Center (read his post), but he is continuing to be a strong presence in the evangelism community.  I have a lot of respect for Vinod.  He has done a lot for the community and technology evangelism.  Everybody has dream to serve community the way he does, and he is a great role model for evangelists everywhere. On his blog, Vinod created one of the best descriptions of a Technology Evangelist.  It defined the position and also made the distinction between evangelist and salesperson extremely clear.  I will include the highlights of that list here, because no one can say it better than Vinod: Bundle of energy – Passion is their middle name Wonderful Story tellers Empathy, Trust, Loyalty, Openness, Accessibility and Warmth Technology Enthusiast – Doers Love people, people and more people – Community oriented Unique Style and Leadership qualities !!! Self-Confident, Self-Motivated but a student (To read the full list, see: Evangelism Beyond Borders with Evangelists) His blog is a must-read for anyone interested in technology evangelism as a career or simply a hobby.  His advice about how to gain an audience and become a trusted advisor is the best in the business. I think there is an evangelist in everyone. I, too, consider myself a technology evangelist.  Regular readers of this blog will recognize that I am dedicated to bringing information to the masses, and that I pride myself on being both brutally and honest and giving every product fair consideration. I think there is no better way of saying following subject. “Once an Evangelist – Always an Evangelist!” Reference: Pinal Dave (http://blog.SQLAuthority.com)     Filed under: About Me, Database, MVP, Pinal Dave, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, SQLAuthority News, T SQL, Technology Tagged: Evangelist

• Change a File Type’s Icon in Windows 7

  - by Trevor Bekolay

  In Windows XP, you could change the icon associated with a file type in Windows Explorer. In Windows 7, you have to do some registry hacking to change a file type’s icon. We’ll show you a much easier and faster method for Windows 7. File Types Manager File Types Manager is a great little utility from NirSoft that includes the functionality of Windows XP’s folder options and adds a whole lot more. It works great in Windows 7, and its interface makes it easy to change a bunch of related file types at once. A common problem we run into are icons that look too similar. You have to look for a few seconds to see the difference between the movies and the text files. Let’s change the icon for the movie files to make visually scanning through directories much easier. Open up File Types Manager. Find the “Default Icon” column and click on it to sort the list by the Default Icon. (We’ve hidden a bunch of columns we don’t need, so you may find it to be farther to the right.) This groups together all file extensions that already have the same icon. This is convenient because we want to change the icon of all video files, which at the moment all have the same default icon. Click the “Find” button on the toolbar, of press Ctrl+F. Type in a file type that you want to change. Note that all of the extensions with the same default icon are grouped together. Right click on the first extension whose icon you want to change and click on Edit Selected File Type, or select the first extension and press F2. Click the “…” button next to the Default Icon text field. Click on the Browse… button. File Types Manager allows you to select .exe, .dll, or .ico files. In our case, we have a .ico file that we took from the wonderful public domain Tango icon library. Select the appropriate icon (if you’re using a .exe or .dll there could be many possible icons) then click OK. Repeat this process for each extension whose icon you would like to change. Now it’s much easier to see at a glance which files are movies and which are text files! Of course, this process will work for any file type, so customize your files’ icons as you see fit.

• Data Quality and Master Data Management Resources

  - by Dejan Sarka

  Many companies or organizations do regular data cleansing. When you cleanse the data, the data quality goes up to some higher level. The data quality level is determined by the amount of work invested in the cleansing. As time passes, the data quality deteriorates, and you need to repeat the cleansing process. If you spend an equal amount of effort as you did with the previous cleansing, you can expect the same level of data quality as you had after the previous cleansing. And then the data quality deteriorates over time again, and the cleansing process starts over and over again. The idea of Data Quality Services is to mitigate the cleansing process. While the amount of time you need to spend on cleansing decreases, you will achieve higher and higher levels of data quality. While cleansing, you learn what types of errors to expect, discover error patterns, find domains of correct values, etc. You don’t throw away this knowledge. You store it and use it to find and correct the same issues automatically during your next cleansing process. The following figure shows this graphically. The idea of master data management, which you can perform with Master Data Services (MDS), is to prevent data quality from deteriorating. Once you reach a particular quality level, the MDS application—together with the defined policies, people, and master data management processes—allow you to maintain this level permanently. This idea is shown in the following picture. OK, now you know what DQS and MDS are about. You can imagine the importance on maintaining the data quality. Here are some resources that help you preparing and executing the data quality (DQ) and master data management (MDM) activities. Books Dejan Sarka and Davide Mauri: Data Quality and Master Data Management with Microsoft SQL Server 2008 R2 – a general introduction to MDM, MDS, and data profiling. Matching explained in depth. Dejan Sarka, Matija Lah and Grega Jerkic: MCTS Self-Paced Training Kit (Exam 70-463): Building Data Warehouses with Microsoft SQL Server 2012 – I wrote quite a few chapters about DQ and MDM, and introduced also SQL Server 2012 DQS. Thomas Redman: Data Quality: The Field Guide – you should start with this book. Thomas Redman is the father of DQ and MDM. Tyler Graham: Microsoft SQL Server 2012 Master Data Services – MDS in depth from a product team mate. Arkady Maydanchik: Data Quality Assessment – data profiling in depth. Tamraparni Dasu, Theodore Johnson: Exploratory Data Mining and Data Cleaning – advanced data profiling with data mining. Forthcoming presentations I am presenting a DQS and MDM seminar at PASS SQL Rally Amsterdam 2013: Wednesday, November 6th, 2013: Enterprise Information Management with SQL Server 2012 – a good kick start to your first DQ and / or MDM project. Courses Data Quality and Master Data Management with SQL Server 2012 – I wrote a 2-day course for SolidQ. If you are interested in this course, which I could also deliver in a shorter seminar way, you can contact your closes SolidQ subsidiary, or, of course, me directly on addresses [email protected] or [email protected]. This course could also complement the existing courseware portfolio of training providers, which are welcome to contact me as well. Start improving the quality of your data now!

• Principles of Big Data By Jules J Berman, O&rsquo;Reilly Media Book Review

  - by Compudicted

  Originally posted on: http://geekswithblogs.net/Compudicted/archive/2013/11/04/principles-of-big-data-by-jules-j-berman-orsquoreilly-media.aspx A fantastic book! Must be part, if not yet, of the fundamentals of the Big Data as a field of science. Highly recommend to those who are into the Big Data practice. Yet, I confess this book is one of my best reads this year and for a number of reasons: The book is full of wisdom, intimate insight, historical facts and real life examples to how Big Data projects get conceived, operate and sadly, yes, sometimes die. But not only that, the book is most importantly is filled with valuable advice, accurate and even overwhelming amount of reference (from the positive side), and the author does not event stop there: there are numerous technical excerpts, links and examples allowing to quickly accomplish many daunting tasks or make you aware of what one needs to perform as a data practitioner (excuse my use of the word practitioner, I just did not find a better substitute to it to trying to reference all who face Big Data). Be aware that Jules Berman’s background is in medicine, naturally, this book discusses this subject a lot as it is very dear to the author’s heart I believe, this does not make this book any less significant however, quite the opposite, I trust if there is an area in science or practice where the biggest benefits can be ripped from Big Data projects it is indeed the medical science, let’s make Cancer history! On a personal note, for me as a database, BI professional it has helped to understand better the motives behind Big Data initiatives, their underwater rivers and high altitude winds that divert or propel them forward. Additionally, I was impressed by the depth and number of mining algorithms covered in it. I must tell this made me very curious and tempting to find out more about these indispensable attributes of Big Data so sure I will be trying stretching my wallet to acquire several books that go more in depth on several most popular of them. My favorite parts of the book, well, all of them actually, but especially chapter 9: Analysis, it is just very close to my heart. But the real reason is it let me see what I do with data from a different angle. And then the next - “Special Considerations”, they are just two logical parts. The writing language is of this book is very acceptable for all levels, I had no technical problem reading it in ebook format on my 8” tablet or a large screen monitor. If I would be asked to say at least something negative I have to state I had a feeling initially that the book’s first part reads like an academic material relaxing the reader as the book progresses forward. I admit I am impressed with Jules’ abilities to use several programming languages and OSS tools, bravo! And I agree, it is not too, too hard to grasp at least the principals of a modern programming language, which seems becomes a defacto knowledge standard item for any modern human being. So grab a copy of this book, read it end to end and make yourself shielded from making mistakes at any stage of your Big Data initiative, by the way this book also helps build better future Big Data projects. Disclaimer: I received a free electronic copy of this book as part of the O'Reilly Blogger Program.

• 11 Types of Developers

  - by Lee Brandt

  Jack Dawson Jack Dawson is the homeless drifter in Titanic. At one point in the movie he says, “I figure life’s a gift, and I don’t intend on wasting it.” He is happy to wander wherever life takes him. He works himself from place to place, making just enough money to make it to his next adventure. The “Jack Dawson” developer clings on to any new technology as the ‘next big thing’, and will find ways to shoe-horn it in to places where it is not a fit. He is very appealing to the other developers because they want to try the newest techniques and tools too, He will only stay until the new technology either bores him or becomes problematic. Jack will also be hard to find once the technology has been implemented, because he will be on to the next shiny thing. However, having a Jack Dawson on your team can be beneficial. Jack can be a great ally when attempting to convince a stodgy, corporate entity to upgrade. Jack usually has an encyclopedic recall of all the new features of the technology upgrade and is more than happy to interject them in any conversation. Tom Smykowski Tom is the neurotic employee in Office Space, and is deathly afraid of being fired. He will do only what is necessary to keep the status quo. He believes as long as nothing changes, his job is safe. He will scoff at anything new and be the naysayer during any change initiative. Tom can be useful in off-setting Jack Dawson. Jack will constantly be pushing for change and Tom will constantly be fighting it. When you see that Jack is getting kind of bored with a new technology and Tom has finally stopped wetting himself at the mere mention of it, then it is probably the sweet spot of beginning to implement that new technology (providing it is the right tool for the job). Ray Consella Ray is the guy who built the Field of Dreams. He took a risk. Sometimes he screwed it up, but he knew he didn’t want to end up regretting not attempting it. He constantly doubted himself, but he knew he had to keep going. Granted, he was doing what the voices in his head were telling him to do, but my point is he was driven to do something that most people considered crazy. Even when his friends, his wife and even he told himself he was crazy, somewhere inside himself, he knew it was the right thing to do. These are the innovators. These are the Bill Gates and Steve Jobs of the world. The take risks, they fail, they learn and the get better. Obviously, this kind of person thrives in start-ups and smaller companies, but that is due to their natural aversion to bureaucracy. They want to see their ideas put into motion quickly, and withdrawn quickly if it doesn’t work. Short feedback cycles are essential to Ray. He wants to know if his idea is working or not. He wants to modify or reverse his idea if it is not working or makes things worse. These are the agilistas. May I always be one.

• Making a Job Change That's Easy Why Not Try a Career Change

  - by david.talamelli

  A few nights ago I received a comment on one of our blog posts that reminded me of a statistic that I heard a while back. The statistic reflected the change in our views towards work and showed how while people in past generations would stay in one role for their working career - now with so much choice people not only change jobs often but also change careers 4-5 times in their working life. To differentiate between a job change and a career change: when I say job change this could be an IT Sales person moving from one IT Sales role to another IT Sales role. A Career change for example would be that same IT Sales person moving from IT Sales to something outside the scope of their industry - maybe to something like an Engineer or Scuba Dive Instructor. The reason for Career changes can be as varied as the people who make them. Someone's motivation could be to pursue a passion or maybe there is a change in their personal circumstances forcing the change or it could be any other number of reasons. I think it takes courage to make a Career change - it can be easy to stay in your comfort zone and do what you know, but to really push yourself sometimes you need to try something new, it is a matter of making that career transition as smooth as possible for yourself. The comment that was posted is here below (thanks Dean for the kind words they are appreciated). Hi David, I just wanted to let you know that I work for a company called Milestone Search in Melbourne, Victoria Australia. (www.mstone.com.au) We subscribe to your feed on a daily basis and find your blogs both interesting and insightful. Not to mention extremely entertaining. I wonder if you have missed out on getting in journalism as this seems to be something you'd be great at ?: ) Anyways back to my point about changing careers. This could be anything from going from I.T. to Journalism, Engineering to Teaching or any combination of career you can think of. I don't think there ever has been a time where we have had so many opportunities to do so many different things in our working life. While this idea sounds great in theory, putting it into practice would be much harder to do I think. First, in an increasingly competitive job market, employers tend to look for specialists in their field. You may want to make a change but your options may be limited by the number of employers willing to take a chance on someone new to an industry that will likely require a significant investment in time to get brought up to speed. Also, using myself as an example if I was given the opportunity to move into Journalism/Communication/Marketing career from my career as an IT Recruiter - realistically I would have to take a significant pay cut to make this change as my current salary reflects the expertise I have in my current career. I would not immediately be up to speed moving into a new career and would not be able to justify a similar salary. Yes there are transferable skills in any career change, but even though you may have transferable skills you must realise that you will also have a large amount of learning to do which would take time. These are two initial hurdles that I immediately think of, there may be more but nothing is insurmountable. If you work out what you want to do with your working career whatever that may be, you then need to just need to work out the steps to get to your end goal. This is where utilising the power of your networks and using Social Media can come in handy. If you are interested in working somewhere why not proactively take the opportunity to research the industry or company - find out who it is you need to speak to and get in touch with them. We spend so much time working, we should enjoy the work we do and not be afraid to try new things. Waiting for your dream job to fall into your lap or be handed to you on a silver platter is not likely going to happen, so if there is something you do want to do, work out a plan to make it happen and chase after it.
