• Pondering New Technology

  - by MOSSLover

  So I have been standing at the end of a fork for a year peering down a corner looking at this way and that way trying to figure out where I fit in.  I was so enthusiastic and excited about Silverlight when it came out.  It was this amazing awesome technology that had this really cool animation and webcam/multimedia piece.  I thought if I put my money on Silverlight it’s going somewhere, then HTML 5 came out and the wind shifted.  I realized times were changing. I have been working with web technologies since I was 15 years old.  Playing with html and javascript and even css back when it first came out.  In tech years 15 years is forever.  Things change so quickly and so often.  So I guess the question is where am I heading?  The answer is mobile technology.  For some reason I was resisting change and I have no idea why.  I guess I really wanted to see more than one player.  I didn’t quite feel that Microsoft was ready with Windows Phone 7.  It was a great start, but it just didn’t feel like they went all the way.  Now with Windows 8 it feels like they are at version 2.0.  It’s like hitting Silverlight 2.0 where they finally added the .Net bits.  The path is paved, but we don’t know where it’s leading.  Then we had 3.0, 4.0, and 5.0 to mature the technology into what it is today (man I’m hoping they are going to roll some of the cool bits into other tech if they don’t exist). Anyway, I’m on board, but I’m not buying a Windows Tablet just yet.  I was hoping for a 7 inch screen from Apple around $300 or just above and a 7 inch screen from the MS side around the same price.  What I got was the Apple side, but nothing from Microsoft.  I was pretty disappointed with the $500 market price on the RT version.  I realized Microsoft is close, but not quite where Apple is today.  Yes the devices have Office that they are offering, but the sticker is just too much for a first generation device.  If you guys remember correctly the first generation iPad was quite expensive.  I guess for a 1st generation device $500 is pretty good. So I guess what I’m trying to say is that I am shifting my focus entirely away from Silverlight and more towards mobile.  I will be doing a lot of postings on iOS, Windows 8, and Windows Phone 8 with SharePoint 2013.  Since I don’t have a tablet and don’t foresee myself buying one just yet it might be mostly on the phones for right now.  I want to do a bunch of testing on various devices on what needs to be done in apps on each device.  I might add a bit on porting code from one to the other.  I think it’s going to be a lot of fun and make things flow a little better for me.  In a way it’s kind of like Star Trek 6 where they talk about the Undiscovered Country.  I’m going to jump forward completely and see where I land.

• Finding the maximum value/date across columns

  - by AtulThakor

  While working on some code recently I discovered a neat little trick to find the maximum value across several columns….. So the starting point was finding the maximum date across several related tables and storing the maximum value against an aggregated record. Here's the sample setup code: USE TEMPDB IF OBJECT_ID('CUSTOMER') IS NOT NULL BEGIN DROP TABLE CUSTOMER END IF OBJECT_ID('ADDRESS') IS NOT NULL BEGIN DROP TABLE ADDRESS END IF OBJECT_ID('ORDERS') IS NOT NULL BEGIN DROP TABLE ORDERS END SELECT 1 AS CUSTOMERID, 'FREDDY KRUEGER' AS NAME, GETDATE() - 10 AS DATEUPDATED INTO CUSTOMER SELECT 100000 AS ADDRESSID, 1 AS CUSTOMERID, '1428 ELM STREET' AS ADDRESS, GETDATE() -5 AS DATEUPDATED INTO ADDRESS SELECT 123456 AS ORDERID, 1 AS CUSTOMERID, GETDATE() + 1 AS DATEUPDATED INTO ORDERS .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   Now the code used a function to determine the maximum date, this performed poorly. After considering pivoting the data I opted for a case statement, this seemed reasonable until I discovered other areas which needed to determine the maximum date between 5 or more tables which didn't scale well. The final solution involved using the value clause within a sub query as followed. SELECT C.CUSTOMERID, A.ADDRESSID, (SELECT MAX(DT) FROM (Values(C.DATEUPDATED),(A.DATEUPDATED),(O.DATEUPDATED)) AS VALUE(DT)) FROM CUSTOMER C INNER JOIN ADDRESS A ON C.CUSTOMERID = A.CUSTOMERID INNER JOIN ORDERS O ON O.CUSTOMERID = C.CUSTOMERID .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } As you can see the solution scales well and can take advantage of many of the aggregate functions!

• Using a parser to locate faulty code

  - by ryan.riverside

  Lately I've been working a lot in PHP and have run into an abnormally large number of parsing errors. I realize these are my own fault and a result of sloppy initial coding on my part, but it's getting to the point that I'm spending more time resolving tags than developing. In the interest of not slamming my productivity, are there any tricks to locating the problem in the code? What I'd really be looking for would be a line to put in the code which would output the entire faulty tag in the parsing error, or something similar. Purely for reference sake, my current error is Parse error: syntax error, unexpected '}' in /home/content/80/9480880/html/cache/tpl_prosilver_viewtopic_body.html.php on line 50 (which refers to this): </dd><dd><?php if ($_poll_option_val['POLL_OPTION_RESULT'] == 0) { echo ((isset($this->_rootref['L_NO_VOTES'])) ? $this->_rootref['L_NO_VOTES'] : ((isset($user->lang['NO_VOTES'])) ? $user->lang['NO_VOTES'] : '{ NO_VOTES }')); } else { echo $_poll_option_val['POLL_OPTION_PERCENT']; } ?></dd> </dl> <?php }} if ($this->_rootref['S_DISPLAY_RESULTS']) { ?> <dl> <dt>&nbsp;</dt> <dd class="resultbar"><?php echo ((isset($this->_rootref['L_TOTAL_VOTES'])) ? $this->_rootref['L_TOTAL_VOTES'] : ((isset($user->lang['TOTAL_VOTES'])) ? $user->lang['TOTAL_VOTES'] : '{ TOTAL_VOTES }')); ?> : <?php echo (isset($this->_rootref['TOTAL_VOTES'])) ? $this->_rootref['TOTAL_VOTES'] : ''; ?></dd> </dl> <?php } if ($this->_rootref['S_CAN_VOTE']) { ?> <dl style="border-top: none;"> <dt>&nbsp;</dt> <dd class="resultbar"><input type="submit" name="update" value="<?php echo ((isset($this->_rootref['L_SUBMIT_VOTE'])) ? $this->_rootref['L_SUBMIT_VOTE'] : ((isset($user->lang['SUBMIT_VOTE'])) ? $user->lang['SUBMIT_VOTE'] : '{ SUBMIT_VOTE }')); ?>" class="button1" /></dd> </dl> <?php } if (! $this->_rootref['S_DISPLAY_RESULTS']) { ?> <dl style="border-top: none;"> <dt>&nbsp;</dt> <dd class="resultbar"><a href="<?php echo (isset($this->_rootref['U_VIEW_RESULTS'])) ? $this->_rootref['U_VIEW_RESULTS'] : ''; ?>"><?php echo ((isset($this->_rootref['L_VIEW_RESULTS'])) ? $this->_rootref['L_VIEW_RESULTS'] : ((isset($user->lang['VIEW_RESULTS'])) ? $user->lang['VIEW_RESULTS'] : '{ VIEW_RESULTS }')); ?></a></dd> </dl> <?php } ?> </fieldset></div>

• How to create Checkboxes that act like Radio buttons with Jquery

  - by hmloo

  I have a post here to show code examples for check/uncheck all checkbox with Jquery. This time I will implement another request that the user should only be able to check at most one of the checkboxes, it's behave like radio buttons. There are 2 cases. Case 1 shows function that has little difference with radio button. It allows the user to deselect checkbox. Case 2 is same as radio button. Case 1 <head id="Head1" runat="server"> <title></title> <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script> <style type="text/css"> .cbRowItem {display:block;} </style> <script type="text/javascript"> $(document).ready(function() { var $chk = $('input:checkbox .cbRowItem'); $chk.click(function() { $chk.not(this).removeAttr('checked'); }); }); </script> </head> <body> <form id="form1" runat="server"> <div style="display:block;"> <asp:CheckBox id="CheckBox1" runat="server" class="cbRowItem" Text = "CheckBox 1"/> <asp:CheckBox id="CheckBox2" runat="server" class="cbRowItem" Text = "CheckBox 2"/> <asp:CheckBox id="CheckBox3" runat="server" class="cbRowItem" Text = "CheckBox 3"/> <asp:CheckBox id="CheckBox4" runat="server" class="cbRowItem" Text = "CheckBox 4"/> </div> </form> </body> </html> Case 2 <head id="Head1" runat="server"> <title></title> <script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script> <style type="text/css"> .cbRowItem {display:block;} </style> <script type="text/javascript"> $(document).ready(function() { var $chk = $('input:checkbox .cbRowItem'); $chk.click(function() { $chk.removeAttr('checked'); $(this).attr('checked', 'checked'); }); }); </script> </head> <body> <form id="form1" runat="server"> <div style="display:block;"> <asp:CheckBox id="CheckBox1" runat="server" class="cbRowItem" Text = "CheckBox 1"/> <asp:CheckBox id="CheckBox2" runat="server" class="cbRowItem" Text = "CheckBox 2"/> <asp:CheckBox id="CheckBox3" runat="server" class="cbRowItem" Text = "CheckBox 3"/> <asp:CheckBox id="CheckBox4" runat="server" class="cbRowItem" Text = "CheckBox 4"/> </div> </form> </body> </html>

• Is there an IDE that can simplify the process of creating a game matchmaking website?

  - by Scott

  Yes, I'm an old guy. And I'm well versed in "C" and have written several games which I have been selling on the web for a number of years. And now, I would like to adapt one of my games to be "online". Sounds simple. I'm sure I can use the thousands of lines of "C" code that I've already written. Right? So my initial investigation begins. First, I think I'll need a server program that lives on a dedicated server (or a VPS probably) that talks to a bunch of client applications that live on individual devices around the world. I can certainly handle that! (I think to myself). I'll break up my existing game into two pieces, a client piece that is just the game displays and buttons, and a server piece that does everything else. Piece of cake, right? But that means that the "server piece" must be executed on a remote machine somewhere and run 24/7. Can I do that? [apparently, that question is so basic, so uneducated, and so lame, that nobody has ever posed it before. Because hours of Googling does not yield an answer. Fine. I'll assume I can do that and move on.] I'll need a "game room", which to me means a website where you log in and then go to a lobby of some kind where you can setup your preferences, see if any of your friends are connected, and create or join games. Should be easy, but it's not. No way. Can I do all this with my local website builder? (which happens to be 90 Second Website Builder, a nice product, btw). It turns out, I can not. I can start with that, but must modify each page, so I can interact with my sql database. So I begin making each page a "PHP" page and dynamically modifying the HTML code with PHP code. I'm already starting to get a headache. Because the resulting web pages looked terrible, I began looking at using JQuery. I want to user a JQuery dialog on my website to display a list of friends and allow the user to select one to invite to the game. [google search for "how to populate a JQuery dialog from a sql database" yields nothing but more confusion.] Javascript? Java? HTML? XML? HTML5? PHP? JQuery? Flash? Sockets? Forms? CSS? Learning about each one of these, and how they interact with each other and/or depend on each other is too much for my feeble old brain. Can anyone simplify this process for me? Is there an IDE that will help me do all this without having to go back to college for a few years? Thanks, Scott

• Modernizr Rocks HTML5

  - by Laila

  HTML5 is a moving target.  At the moment, we don't know what will be in future versions.  In most circumstances, this really matters to the developer. When you're using Adobe Air, you can be reasonably sure what works, what is there, and what isn't, since you have a version of the browser built-in. With Metro, you can assume that you're going to be using at least IE 10.   If, however,  you are using HTML5 in a web application, then you are going to rely heavily on Feature Detection.  Feature-Detection is a collection of techniques that tell you, via JavaScript, whether the current browser has this feature natively implemented or not Feature Detection isn't just there for the esoteric stuff such as  Geo-location,  progress bars,  <canvas> support,  the new <input> types, Audio, Video, web workers or storage, but is required even for semantic markup, since old browsers make a pigs ear out of rendering this.  Feature detection can't rely just on reading the browser version and inferring from that what works. Instead, you must use JavaScript to check that an HTML5 feature is there before using it.  The problem with relying on the user-agent is that it takes a lot of historical data  to work out what version does what, and, anyway, the user-agent can be, and sometimes is, spoofed. The open-source library Modernizr  is just about the most essential  JavaScript library for anyone using HTML5, because it provides APIs to test for most of the CSS3 and HTML5 features before you use them, and is intelligent enough to alter semantic markup into 'legacy' 'markup  using shims  on page-load  for old browsers. It also allows you to check what video Codecs are installed for playing video. It also provides media queries  and conditional resource-loading (formerly YepNope.js.).  Generally, Modernizr gives you the choice of what you do about browsers that don't support the feature that you want. Often, the best choice is graceful degradation, but the resource-loading feature allows you to dynamically load JavaScript Shims to replace the standard API for missing or defective HTML5 functionality, called 'PolyFills'.  As the Modernizr site says 'Yes, not only can you use HTML5 today, but you can use it in the past, too!' The evolutionary progress of HTML5  requires a more defensive style of JavaScript programming where the programmer adopts a mindset of fearing the worst ( IE 6)  rather than assuming the best, whilst exploiting as many of the new HTML features as possible for the requirements of the site or HTML application.  Why would anyone want the distraction of developing their own techniques to do this when  Modernizr exists to do this for you?

• SQL analytical mash-ups deliver real-time WOW! for big data

  - by KLaker

  One of the overlooked capabilities of SQL as an analysis engine, because we all just take it for granted, is that you can mix and match analytical features to create some amazing mash-ups. As we move into the exciting world of big data these mash-ups can really deliver those "wow, I never knew that" moments. While Java is an incredibly flexible and powerful framework for managing big data there are some significant challenges in using Java and MapReduce to drive your analysis to create these "wow" discoveries. One of these "wow" moments was demonstrated at this year's OpenWorld during Andy Mendelsohn's general keynote session.  Here is the scenario - we are looking for fraudulent activities in our big data stream and in this case we identifying potentially fraudulent activities by looking for specific patterns. We using geospatial tagging of each transaction so we can create a real-time fraud-map for our business users. Where we start to move towards a "wow" moment is to extend this basic use of spatial and pattern matching, as shown in the above dashboard screen, to incorporate spatial analytics within the SQL pattern matching clause. This will allow us to compute the distance between transactions. Apologies for the quality of this screenshot….hopefully below you see where we have extended our SQL pattern matching clause to use location of each transaction and to calculate the distance between each transaction: This allows us to compare the time of the last transaction with the time of the current transaction and see if the distance between the two points is possible given the time frame. Obviously if I buy something in Florida from my favourite bike store (may be a new carbon saddle for my Trek) and then 5 minutes later the system sees my credit card details being used in Arizona there is high probability that this transaction in Arizona is actually fraudulent (I am fast on my Trek but not that fast!) and we can flag this up in real-time on our dashboard: In this post I have used the term "real-time" a couple of times and this is an important point and one of the key reasons why SQL really is the only language to use if you want to analyse  big data. One of the most important questions that comes up in every big data project is: how do we do analysis? Many enlightened customers are now realising that using Java-MapReduce to deliver analysis does not result in "wow" moments. These "wow" moments only come with SQL because it is offers a much richer environment, it is simpler to use and it is faster - which makes it possible to deliver real-time "Wow!". Below is a slide from Andy's session showing the results of a comparison of Java-MapReduce vs. SQL pattern matching to deliver our "wow" moment during our live demo.  You can watch our analytical mash-up "Wow" demo that compares the power of 12c SQL pattern matching + spatial analytics vs. Java-MapReduce  here: You can get more information about SQL Pattern Matching on our SQL Analytics home page on OTN, see here http://www.oracle.com/technetwork/database/bi-datawarehousing/sql-analytics-index-1984365.html.  You can get more information about our spatial analytics here: http://www.oracle.com/technetwork/database-options/spatialandgraph/overview/index.html If you would like to watch the full Database 12c OOW presentation see here: http://medianetwork.oracle.com/video/player/2686974264001

• MVC Portable Areas &ndash; Static Files as Embedded Resources

  - by Steve Michelotti

  This is the third post in a series related to build and deployment considerations as I’ve been exploring MVC Portable Areas: #1 – Using Web Application Project to build portable areas #2 – Conventions for deploying portable area static files #3 – Portable area static files as embedded resources In the last post, I walked through a convention for managing static files.  In this post I’ll discuss another approach to manage static files (e.g., images, css, js, etc.).  With this approach, you *also* compile the static files as embedded resources into the assembly similar to the *.aspx pages. Once again, you can set this to happen automatically by simply modifying your *.csproj file to include the desired extensions so you don’t have to remember every time you add a file: 1: <Target Name="BeforeBuild"> 2: <ItemGroup> 3: <EmbeddedResource Include="**\*.aspx;**\*.ascx;**\*.gif;**\*.css;**\*.js" /> 4: </ItemGroup> 5: </Target> We now need a reliable way to serve up these static files that are embedded in the assembly. There are a couple of ways to do this but one way is to simply create a Resource controller whose job is dedicated to doing this. 1: public class ResourceController : Controller 2: { 3: public ActionResult Index(string resourceName) 4: { 5: var contentType = GetContentType(resourceName); 6: var resourceStream = Assembly.GetExecutingAssembly().GetManifestResourceStream(resourceName); 7:   8: return this.File(resourceStream, contentType); 9: return View(); 10: } 11:   12: private static string GetContentType(string resourceName) 13: { 14: var extention = resourceName.Substring(resourceName.LastIndexOf('.')).ToLower(); 15: switch (extention) 16: { 17: case ".gif": 18: return "image/gif"; 19: case ".js": 20: return "text/javascript"; 21: case ".css": 22: return "text/css"; 23: default: 24: return "text/html"; 25: } 26: } 27: } In order to use this controller, we need to make sure we’ve registered the route in our portable area registration (shown in lines 5-6): 1: public class WidgetAreaRegistration : PortableAreaRegistration 2: { 3: public override void RegisterArea(System.Web.Mvc.AreaRegistrationContext context, IApplicationBus bus) 4: { 5: context.MapRoute("ResourceRoute", "widget1/resource/{resourceName}", 6: new { controller = "Resource", action = "Index" }); 7:   8: context.MapRoute("Widget1", "widget1/{controller}/{action}", new 9: { 10: controller = "Home", 11: action = "Index" 12: }); 13:   14: RegisterTheViewsInTheEmbeddedViewEngine(GetType()); 15: } 16:   17: public override string AreaName 18: { 19: get { return "Widget1"; } 20: } 21: } In my previous post, we relied on a custom Url helper method to find the actual physical path to the static file like this: 1: <img src="<%: Url.AreaContent("/images/arrow.gif") %>" /> Hello World! However, since we are now embedding the files inside the assembly, we no longer have to worry about the physical path. We can change this line of code to this: 1: <img src="<%: Url.Resource("Widget1.images.arrow.gif") %>" /> Hello World! Note that I had to fully quality the resource name (with namespace and physical location) since that is how .NET assemblies store embedded resources. I also created my own Url helper method called Resource which looks like this: 1: public static string Resource(this UrlHelper urlHelper, string resourceName) 2: { 3: var areaName = (string)urlHelper.RequestContext.RouteData.DataTokens["area"]; 4: return urlHelper.Action("Index", "Resource", new { resourceName = resourceName, area = areaName }); 5: } This method gives us the convenience of not having to know how to construct the URL – but just allowing us to refer to the resource name. The resulting html for the image tag is: 1: <img src="/widget1/resource/Widget1.images.arrow.gif" /> so we can always request any image from the browser directly. This is almost analogous to the WebResource.axd file but for MVC. What is interesting though is that we can encapsulate each one of these so that each area can have it’s own set of resources and they are easily distinguished because the area name is the first segment of the route. This makes me wonder if something like this ResourceController should be baked into portable areas itself. I’m definitely interested in anyone has any opinions on it or have taken alternative approaches.

• Review&ndash;Build Android and iOS apps in Visual Studio with Nomad

  - by Bill Osuch

  Nomad is a Visual Studio extension that allows you build apps for both Android and iOS platforms in Visual Studio using HTML5. There is no need to switch between .Net, Java and Objective-C to target different platforms - write your code once in HTML5 and build for all common mobile platforms and tablets. You have access to the native hardware functions (such as camera and GPS) through the PhoneGap library, UI libraries such as jQuery mobile allow you to create an impressive UI with minimal work. Nomad is still in an early access beta stage, so the documentation is a bit sparse. In fact, the only documentation is a simple series of steps on how to install the plug-in, set up a project, build and deploy it. You're going to want to be a least a little familiar with the PhoneGap library and jQuery mobile to really tap into the power of this. The sample project included with the download shows you just how simple it is to create projects in Visual Studio. The sample solution comes with an index.html file containing the HTML5 code, the Cordova (PhoneGap) library, jQuery libraries, and a JQuery style sheet: The html file is pretty straightforward. If you haven't experimented with JQuery mobile before, some of the attributes (such as data-role) might be new to you, but some quick Googling will fill in everything you need to know. The first part of the file builds a simple (but attractive) list with some links in it: The second part of the file is where things get interesting and it taps into the PhoneGap library. For instance, it gets the geolocation position by calling position.coords.latitude and position.coords.longitude: ...and then displays it in a simple span: Building is pretty simple, at least for Android (I'm not an iOS developer so I didn't look at that feature) - just configure the display name, version number, and package ID. There's no need to specify Android version; Nomad supports 2.2 and later. Enter these bits of information, click the new "Build for Android" button (not the regular Visual Studio Build link...) and you get a dialog box saying that your code is being built by their cloud build service (so no building while away from a WiFi signal apparently). After a couple minutes you wind up with a .apk file that can be copied over to your device. Applications built with Nomad for Android currently use a temporary certificate, so you can test the app on your devices but you cannot publish them in the Google Play Store (yet). And I love the "success" dialog box: Since Nomad is still in Beta, no pricing plans have been announced yet, so I'll be curious to see if this becomes a cost-effective solution to mobile app development. If it is, I may even be tempted to spring for the $99 iOS membership fee! In the meantime, I plan to work on porting some of my apps over to it and seeing how they work. My only quibble at this time is the lack of a centralized documentation location - I'd like to at least see which (if any) features of JQuery and PhoneGap are limited or not supported. Also, some notes on targeting different Android screen sizes would be nice, but it's relatively easy to find jQuery examples out on the InterWebs. Oh well, trial and error! You can download the Nomad extension for Visual Studio by going to their web site: www.vsnomad.com. Technorati Tags: Android, Nomad

• JavaOne Latin America 2012 Trip Report

  - by reza_rahman

  JavaOne Latin America 2012 was held at the Transamerica Expo Center in Sao Paulo, Brazil on December 4-6. The conference was a resounding success with a great vibe, excellent technical content and numerous world class speakers. Some notable local and international speakers included Bruno Souza, Yara Senger, Mattias Karlsson, Vinicius Senger, Heather Vancura, Tori Wieldt, Arun Gupta, Jim Weaver, Stephen Chin, Simon Ritter and Henrik Stahl. Topics covered included the JCP/JUGs, Java SE 7, HTML 5/WebSocket, CDI, Java EE 6, Java EE 7, JSF 2.2, JMS 2, JAX-RS 2, Arquillian and JavaFX. Bruno Borges and I manned the GlassFish booth at the Java Pavilion on Tuesday and Webnesday. The booth traffic was decent and not too hectic. We met a number of GlassFish adopters including perhaps one of the largest GlassFish deployments in Brazil as well as some folks migrating to Java EE from Spring. We invited them to share their stories with us. We also talked with some key members of the local Java community. Tuesday evening we had the GlassFish party at the Tribeca Pub. The party was definitely a hit and we could have used a larger venue (this was the first time we had the GlassFish party in Brazil). Along with GlassFish enthusiasts, a number of Java community leaders were there. We met some of the same folks again at the JUG leader's party on Wednesday evening. On Thursday Arun Gupta, Bruno Borges and I ran a hands-on-lab on JAX-RS, WebSocket and Server-Sent Events (SSE) titled "Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket". This is the same Java EE 7 lab run at JavaOne San Francisco. The lab provides developers a first hand glipse of how an HTML 5 powered Java EE application might look like. We had an overflow crowd for the lab (at one point we had about twenty people standing) and the lab went very well. The slides for the lab are here: Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket from Reza Rahman The actual contents for the lab is available here. Give me a shout if you need help getting it up and running. I gave two solo talks following the lab. The first was on JMS 2 titled "What’s New in Java Message Service 2". This was essentially the same talk given by JMS 2 specification lead Nigel Deakin at JavaOne San Francisco. I talked about the JMS 2 simplified API, JMSContext injection, delivery delays, asynchronous send, JMS resource definition in Java EE 7, standardized configuration for JMS MDBs in EJB 3.2, mandatory JCA pluggability and the like. The session went very well, there was good Q & A and someone even told me this was the best session of the conference! The slides for the talk are here: What’s New in Java Message Service 2 from Reza Rahman My last talk for the conference was on JAX-RS 2 in the keynote hall. Titled "JAX-RS 2: New and Noteworthy in the RESTful Web Services API" this was basically the same talk given by the specification leads Santiago Pericas-Geertsen and Marek Potociar at JavaOne San Francisco. I talked about the JAX-RS 2 client API, asyncronous processing, filters/interceptors, hypermedia support, server-side content negotiation and the like. The talk went very well and I got a few very kind complements afterwards. The slides for the talk are here: JAX-RS 2: New and Noteworthy in the RESTful Web Services API from Reza Rahman On a more personal note, Sao Paulo has always had a special place in my heart as the incubating city for Sepultura and Soulfy -- two of my most favorite heavy metal musical groups of all time! Consequently, the city has a perpertually alive and kicking metal scene pretty much any given day of the week. This time I got to check out a solid performance by local metal gig Republica at the legendary Manifesto Bar. I also wanted to see a Dio Tribute at the Blackmore but ran out of time and energy... Overall I enjoyed the conference/Sao Paulo and look forward to going to Brazil again next year!

• DallasXAML.com – A New User Group for Silverlight, WPF, XBAP, etc.

  - by vblasberg

                                   http://DallasXAML.com   I’ve devoted much of last month to starting the DallasXAML User Group.  I finally got back into user group management after 2 years away from leading the Dallas C# SIG.  Now I’m having fun getting a Silverlight/WPF user group going strong for the Dallas / Ft. Worth community.  Our first meeting was March 3rd at the Improving Enterprises offices in North Dallas.  We had about 25 to 35 attendees in the first meeting and it went well.  We covered the most important topic that everyone should understand well – data binding.   So I chose the XAML user group so we can get together for a common group improvement in the Dallas / Ft. Worth area and learn cross-technology information that we can use now.  It is not a lecture hall.  The great thing is that we’ll provide hands-on experience with most every meeting.  The goal is to get the experience that we can use the next work day.  I unfortunately broke that rule by speaking all through the first meeting, but next month is part two with more hands-on data binding.   The differentiation is this group concentrates on XAML, not Silverlight or Windows Client alone.  What we learn in one area, we gain for all areas.  That includes the Silverlight for Windows Phone 7 coming later this year.  Next year it may be Windows Phone 8, 9, or whatever.    I started developing WPF seriously almost a year ago.  I experienced the painful learning curve.  Anyone who reports that there isn’t a big learning curve either thinks in XAML before it was developed, is on the Silverlight or WPF development team, or has already conquered the learning and forgot the pain.  So I wanted to share the pain or make it easier for others – same thing.  I have found that the more I learn and use good disciplined techniques, the more interesting and rewarding development is again.   A few months ago, I was sitting in the iPhone development session at the Dallas C# SIG.  After the meeting, the audience was polled for future topics.  After a few suggestions, Silverlight got the big hands up.  That makes sense because it’s still the hot topic for many Microsoft developers.  So I surfed around and found that there aren’t enough user groups to help in this area.  I polled a few local group leaders and did the work to start the group.  This week I got a telerik controls licence and improved the site with some great controls, namely the RadHtmlPlaceholder control.  It provides a Silverlight control to show HTML in an IFrame-like area.  On DallasXAML.com, the newsletters and resource pages display in HTML because Silverlight just isn’t there yet.  I’m looking forward to a Silverlight XPS viewer with flow documents.  There are some good commercial version available, but this is a non-profit group.    The DallasXAML.com site points to many other resources such as podcasts and webcasts.  I would rather give them the credit than try to out-do them.  So check out the DallasXAML user group site and attend our meetings if you can.  We meet the first Tuesday of the month.   -Vince DallasXAML User Group Leader

• VirtualBox Clone Root HD / Ubuntu / Network issue

  - by john.graves(at)oracle.com

  When you clone a root Ubuntu disk in VirtualBox, one thing that gets messed up is the network card definition.  This is because Ubuntu (as it should) uses UDEV IDs for the network device.  When you boot your new disk, the network device ID has changed, so it creates a new eth1 device.  Unfortunately, this conflicts with the VirtualBox network setup.  What to do? Boot the box (no network) Edit the /etc/udev/rules.d/70-persistent-net.rules Delete the eth0 line and modify the eth1 line to be eth0 --------- Example OLD ----------- # This file was automatically generated by the /lib/udev/write_net_rules # program, run by the persistent-net-generator.rules rules file. # # You can modify it, as long as you keep each rule on a single # line, and change only the value of the NAME= key. # PCI device 0x8086:0x100e (e1000) <-------------------- Delete these two lines SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:d8:8d:15", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x8086:0x100e (e1000) ---Modify the next line and change eth1 to be eth0 SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:89:84:98", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } ---------------------------------------- --------- Example NEW ----------- # This file was automatically generated by the /lib/udev/write_net_rules # program, run by the persistent-net-generator.rules rules file. # # You can modify it, as long as you keep each rule on a single # line, and change only the value of the NAME= key. # PCI device 0x8086:0x100e (e1000) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:89:84:98", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } ----------------------------------------

• EPM troubleshooting Utilities

  - by THE

  (in via Maurice) "Are you keeping up-to-date with the latest troubleshooting utilities introduced from EPM 11.1.2.2? These are typically not described in product documentation, so you might miss references to them. The following five utilities may be run from the command line.(1) Deployment Report was introduced with EPM 11.1.2.2 (11 April 2012). It details logical web addresses, web servers, application ports, database connections, user directories, database repositories configured for the EPM system, data directories used by EPM system products, instance directories, FMW homes, deployment distory, et cetera. It also helps to keep you honest about whether you made changes to the system and at what times! Download Shared Services patch 13530721 to get the backported functionality in EPM 11.1.2.1. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/epmsys_registry.sh report deployment (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\epmsys_registry.bat report deployment (on Microsoft Windows). The output is saved under \Oracle\Middleware\user_projects\epmsystem1\diagnostics\reports\deployment_report.html (2) Log Analysis has received more "press". It was released with EPM 11.1.2.3 and helps the user to slice and dice EPM logs. It has many parameters which are documented when run without parameters, when run with the -h parameter, or in the 'Readme' file. It has also been released as a standalone utility for EPM 11.1.2.3 and earlier versions. (Sign in to  My Oracle Support, click the 'Patches & Updates' tab, enter the patch number 17425397, and click the Search button. Download the appropriate platform-specific zip file, unzip, and read the 'Readme' file. Note that you must provide a proper value to a JAVA_HOME environment variable [pointer to the mother directory of the Java /bin subdirectory] in the loganalysis.bat | .sh file and use the -d parameter when running standalone.) Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/loganalysis.sh -h (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\loganalysis.bat -h (on Microsoft Windows). The output is saved under the \Oracle\Middleware\user_projects\epmsystem1\diagnostics\reports\ subdirectory. (3) The Registry Cleanup command may be used (without fear!) to clean up various corruptions which can  affect the Hyperion (database-based) Repository. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/registry-cleanup.sh (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\registry-cleanup.bat (on Microsoft Windows). The actions are described on the command line. (4) The Remove Instance Command is only used if there are two or more instances configured on one computer and one of those should be deleted. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/remove-instance.sh (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\remove-instance.bat (on Microsoft Windows). (5) The Reset Configuration Tool was introduced with EPM 11.1.2.2. It nullifies Shared Services Hyperion Registry settings so that a service may be reconfigured. You may locate the values to substitute for <product> or <task> by scanning registry.html (generated by running epmsys_registry.bat | .sh). Find productNAME in INSTANCE_TASKS_CONFIGURATION and SYSTEM_TASKS_CONFIGURATION nodes and identify tasks by property pairs that have values of 'Configurated' or 'Pending'. Run it from /Oracle/Middleware/user_projects/epmsystem1/bin/resetConfigTask.sh -product <product> -task <task> (on Unix/Linux)\Oracle\Middleware\user_projects\epmsystem1\bin\resetConfigTask.bat -product <product> -task <task> (on Microsoft Windows). "Thanks to Maurice for this collection of utilities.

• What is the best practice, point of view of well experienced developers

  - by Damien MIRAS

  My manager pushes me to use his self defined best practices. All of these practices are based on is own assumptions. I disagree with them and I would like to have some feedback of well experienced people about these practices. I would prefer answers from people involved in the maintenance of huge products and people whom have maintained the product for years. Developers with 15+ years of experience are preferred because my manager has that much experience himself. I have 7 years of experience. Here are the practices he wants me to use: never extends classes, use composition and interface instead because extending classes are unmaintainable and difficult to debug. What I think about that Extend when needed, respect "Liskov's Substitution Principle" and you'll never be stuck with a problem, but prefer composition and decoration. I don't know any serious project which has banned inheriting, sometimes it's impossible to not use that, i.e. in a UI framework. Design patterns are just unusable. In PHP, for simple use cases (for example a user needs a web interface to view a database table), his "best practice" is: copy some random php code wich we own, paste and modify it, put html and php code in same file, never use classes in PHP, it doesn't work well for small jobs, and in fact it doesn't work well at all, there is no good tool to work with. Copy & paste PHP code is good practice for maintenance because scripts are independent, if you have a bug somewhere you can fix it without side effects. What I think about that: NEVER EVER COPY code or do it because you have five minutes to deliver something, you will do some refactoring after that. Copy & paste code is a beginners error, if you have errors you'll have the error everywhere any time you have pasted it's a nightmare to maintain. If you repsect the "Open Close Principle" you'll rarely get edge effects, use unit test if you are afraid of that. For small jobs in PHP use at least something you get or write the HTML separately from the PHP code and reuse it any time you need it. Classes in PHP are mature, not as mature as other languages like python or java, but they are usable. There is tools to work with classes in PHP like Zend Studio that work very well. The use of classes or not depends not on the language you use but the programming paradigm you have choosen. I'm a OOP developer, I use PHP5, why do I have to shoot myself in the foot? When you find a simple bug in the code, and you can fix it simply, if you are not working on the code where you have found it, never fix it, even if it takes 5 seconds. He says to me his "best practices" are driven by the fact that he has a lot of experience in maintaining software in production (14 years) and he now knows what works and what doesn't work, what the community says is a fad, and the people advocating such principles as never copy & paste code, are not evolved in maintaining applications. What I think about that: If you find a bug fix it if you can do it quickly inform the people who've touched that code before, check if you have not introduced a new bug, ideally add a unit test for it. I currently work on a web commerce project, which serves 15k unique users per day. The code base has to be maintained and has been maintained this way since 2005. Ideally you include a short description of your position and experience in terms of years effectively maintaining an application which has been in production for real.

• Single page not appearing in Google Search

  - by Dan

  Description I have a static franchise website which has various sub pages each dedicated to an individual franchisee. For each franchisee the page, the only thing slightly similar between all of them are the page titles, they follow this structure: <title> Welcome to THE_COMPANY - PRODUCT_DESCRIPTION Services, THE_LOCATION </title> THE_COMPANY and PRODUCT_DESCRIPTION are the same across all franchisees, however THE_LOCATION changes depeding on where they are located in the UK. Each franchisee page has the following <meta /> tags: <meta name="DC.creator" content="user"/> <meta name="DC.format" content="text/html"/> <meta name="DC.language" content="en"/> <meta name="DC.date.modified" content="2014-01-23T11:22:31+00:00"/> <meta name="DC.date.created" content="2014-01-23T11:22:09+00:00"/> <meta name="DC.type" content="Page"/> <meta name="DC.distribution" content="Global"/> <meta name="robots" content="ALL"/> <meta name="distribution" content="Global"/> The main content on each franchisee page is completely different. The Problem There is one particular franchisee page, located in Area A.. Which will not appear in Google Search results at all. However every single other franchisee (if you Google Search for "THE_COMPANY, THE_LOCATION" is number 1). And if I do the same search on Bing, Yahoo or DuckDuckGo, the Area A franchisee is the first result on all of them. Has Google for some reason black listed one page on the site? What I Have Tried Ensuring the page is referenced in my sitemap.xml file 'Fetching as Google Bot' the link www.the_company.co.uk/areaa When that came back as OK I would submit to index Resubmitting the sitemap.xml file in Webmaster Tools Linking to the Area A page from another pages content For this I also waited about 3 weeks before checking again to give Google time to re-index Making a change to the page content and waiting another 2 / 3 weeks Removing the page completely and recreating it with an alternative URL The closest thing I have found to this issue is this StackOverflow question but this particular franchisee has existed for almost a year, it used to appear on Google searches however no longer does. I'm guessing the Panda update wasn't too happy with something on the page, but it hasn't effected anything else on the site and I am at a loss for things to try. I would greatly appreciate any information or thoughts as to what could have caused this Thanks. Update In line with Daniel Fukudas answer below, I have followed some of his steps but everything seems to check out alright: HTTP Headers HTTP/1.1 200 OK => Date => Tue, 25 Feb 2014 16:31:29 GMT Server => Zope/(2.12.16, python 2.6.6, linux2) ZServer/1.1 Content-Length => 40078 Expires => Sat, 01 Jan 2000 00:00:00 GMT Content-Type => text/html;charset=utf-8 Content-Language => en Vary => Accept-Encoding Connection => close Robots <meta /> tag: <meta name="robots" content="ALL"/> I have updated this <meta /> tag to read content="INDEX" instead now. robots.txt: User-agent: * Disallow: User-Agent: Googlebot Disallow: /*sendto_form$ Disallow: /*folder_factories$ Using site:THE_COMPANY.co.uk: Searching for 'AREA A site:THE_COMPANY.co.uk' does not return the page, but regardless of that searching just for site:THE_COMPANY.co.uk will not necessarily return every indexed page, or so I understand... Update It appears Google likes to drop pages every now and then from the index, despite my steps above, I left the site alone and the page appeared back in the SERPs by itself.

• Refactoring existing PHP Project. I need some advices

  - by b0x

  i have a small SAS ERP that was written some years ago using PHP. At that time, it didn't used any framework, but the code isn't a mess as i will explain more detailed in the following lines. Nowadays, the project grow and I’m now working with 3 more programmers. Often, they ask to me why we don’t migrate to a framework such Laravel. Although I'd love trying Laravel, I’m a small business and i don't have time/money to stop and spend a whole year building everything from scratch. I need to live and pay the bills. So, I've read a lot about this matter, and I decided that doing a refactoring is the best way to do it. Also, I'm not so sure that a framework will make things easy. Business goals are: Make the code easier to new hired programmers I must separate the "view", because: I want to release different versions of this product (using the same code), but under different brands and websites at the minimum cost (just changing view) Release different versions to fit mobile/tablet. Make different types of this product, seeling packages as if it were plugins. Develop custom packages for some costumers (like plugins/addon's that they can buy to put on the main application). Code goals: Introduce best pratices, standards for everyone Try to build my own MVC structure Improve validation of data/forms (today they are mixed in both ajax and classes) Create automated testing rotines, to quality assurance. My actual structure project: class\ extra\ hd\ logs\ public_html\ public_html\includes\ public_html\css|js|images\ class\ There are three types of classes. They are all “autoloaded” with something similar with PSR-0, but I don’t use namespaces. 1. class.Something.php Connects to Database using specific methods. I.e: Costumer-list(); It uses “class.Db.php”, that it’s an abstraction of mysqli on every method. 2. class.SomethingProc.php Do things that “join” things that come from “class.Something.php”. Like IF/ELSE, math operations. 3. class.SomethingHTML.php The classes with “HTML” suffix implements only static methods and HTML code only. A real life example: All the programmers need to use $cSomething ($c to class) and $arrSomething (to array). Costumer.php (view) <?php $cCosumter = new Costumer(); $arrCostumer = $cCostumer->list(); echo CostumerHTML::table($arrCostumer); ?> Extra\ Store 3rdparty projects/classes from others, such MPDF, PHPMailer, etc. Hd\ Store user’s fies outsite wwwroot dir. Logs\ Store phplogs and the system itself logs (We have a static Log::error() method, that we put in every method of every class) Public_html\ Stores the files that people use. Public_html\includes\ Store the main “config.php” file and all files that do “ajax things” ajax.Costumer.php, for example. Help is needed ;) So, as you can see we have some standards, and also for database things. But i want to write a manual of our rules. Something that i can give to any new programmer at my companie and he can go on. This is not totally a mess, but It could be better seeing the new practices. What could I do to separate this as MVC, to have multiple VIEW’s. Could you gimme some tips considering my goals? Keep im mind the different products/custom things for specific costumers without breaking the main application. URL for tutorials, books, etc. It would be nice. Thanks!

• Rotating WebLogic Server logs to avoid large files using WLST.

  - by adejuanc

  By default, when WebLogic Server instances are started in development mode, the server automatically renames (rotates) its local server log file as SERVER_NAME.log.n.  For the remainder of the server session, log messages accumulate in SERVER_NAME.log until the file grows to a size of 500 kilobytes.Each time the server log file reaches this size, the server renames the log file and creates a new SERVER_NAME.log to store new messages. By default, the rotated log files are numbered in order of creation filenamennnnn, where filename is the name configured for the log file. You can configure a server instance to include a time and date stamp in the file name of rotated log files; for example, server-name-%yyyy%-%mm%-%dd%-%hh%-%mm%.log.By default, when server instances are started in production mode, the server rotates its server log file whenever the file grows to 5000 kilobytes in size. It does not rotate the local server log file when the server is started. For more information about changing the mode in which a server starts, see Change to production mode in the Administration Console Online Help.You can change these default settings for log file rotation. For example, you can change the file size at which the server rotates the log file or you can configure a server to rotate log files based on a time interval. You can also specify the maximum number of rotated files that can accumulate. After the number of log files reaches this number, subsequent file rotations delete the oldest log file and create a new log file with the latest suffix.  Note: WebLogic Server sets a threshold size limit of 500 MB before it forces a hard rotation to prevent excessive log file growth.

• Recieving and organizing results without server side script (JavaScript)

  - by Aaron

  I have been working on a very large form project for the past few days. I finally managed to get tables to work properly within a javascript file that opens a new display window. Now the issue at hand is that I can't seem to get CSS code to work within the javascript that I have created. Before everyone starts thinking "just use server side script idiot" I have a few conditions and info about the file: The file is only being ran local due to confidential information risks. Once again no option for server access. The intranet the computers are on are already top security and this wouldn't exactly be a company wide program The code below is obviously just a demo with a simple form... The real file has six pages of highly confidential information Only certain fields on this form will actually be gathered (example: address doesnt appear in the results) The display page will contain data compiled into tables for easier viewing I need to be able to create css commands to easily detect certain information if it applies and along with matching design of the original form Here is the code: <html> <head> <title>Form Example</title> <script LANGUAGE="JavaScript" type="text/javascript"> function display() { DispWin = window.open('','NewWin', 'toolbar=no,status=no,width=800,height=600') message = "<body>"; message += "<table border=1 width=100%>"; message += "<tr>"; message += "<th colspan=2 align=center><font face=stencil color=black><h1>Results</h1><h4>one</h4></font>"; message += "</th>"; message += "</tr>"; message += "<td width=50% align=left>"; message += "<ul><li><b><font face=calibri color=red>NAME:</font></b> " + document.form1.yourname.value + "</UL>" message += "</td>"; message += "<td width=50% align=left>"; message += "<li><b>PHONE: </b>" + document.form1.phone.value + "</ul>"; message += "</td>"; message += "</table>"; message += "<body>"; DispWin.document.write(message); DispWin.document.body.style.cssText = 'color:#blue;'; } </script> </head> <body> <h1>Form Example</h1> Enter the following information: <form name="form1"> <p><b>Name:</b> <input TYPE="TEXT" SIZE="20" NAME="yourname"> </p> <p><b>Address:</b> <input TYPE="TEXT" SIZE="30" NAME="address"> </p> <p><b>Phone: </b> <input TYPE="TEXT" SIZE="15" NAME="phone"> </p> <p><input TYPE="BUTTON" VALUE="Display" onClick="display();"></p> </form> </body> </html> >

• How to automate a monitoring system for ETL runs

  - by Jeffrey McDaniel

  Upon completion of the Primavera ETL process there are a few ways to determine if the process finished successfully.  First, in the <installation directory>\log folder,  there is a staretlprocess.log and staretl.html files. These files will give the output results of the ETL run. The staretl.html file will give a detailed summary of each step of the process, its run time, and its status. The .log file, based on the logging level set in the Configuration tool, can give extensive information about the ETL process. The log file can be used as a validation for process completion.  To automate the monitoring of these log files, perform the following steps: 1. Write a custom application to parse through the log file and search for [ERROR] . In most cases,  a major [ERROR] could cause the ETL process to fail. Searching the log and finding this value is worthy of an alert. 2. Determine the total number of steps in the ETL process, and validate that the log file recorded and entry for the final step.  For example validate that your log file contains an entry for Step 39/39 (could be different based on the version you are running). If there is no Step 39/39, then either the process is taking longer than expected or it didn't make it to the end.  Either way this would be a good cause for an alert. 3. Check the last line in the log file. The last line of the log file should contain an indication that the ETL run completed successfully. For example, the last line of a log file will say (results could be different based on Reporting Database versions):   [INFO] (Message) Finished Writing Report 4. You could write an Ant script to execute the ETL process and have it set to - failonerror="true" - and from there send results to an external tool to monitor the jobs, send to email, or send to database. With each ETL run, the log file appends to the existing log file by default. Because of this behavior, I would recommend renaming the existing log files before running a new ETL process. By doing this,  only log entries for the currently running ETL process is recorded in the new log files. Based on these log entries, alerts can be setup to notify the administrator or DBA. Another way to determine if the ETL process has completed successfully is to monitor the etl_processmaster table.  Depending on the Reporting Database version this could be in the Stage or Star databases. As of Reporting Database 2.2 and higher this would be in the Star database.  The etl_processmaster table records entries for the ETL run along with a Start and Finish time.  If the ETl process has failed the Finish date should be null. This table can be queried at a time when ETL process is expected to be finished and if null send an alert.  These are just some options. There are additional ways this can be accomplished based around these two areas - log files or database. Here is an additional query to gather more information about your ETL run (connect as Staruser): SELECT SYSDATE,test_script,decode(loc, 0, PROCESSNAME, trim(SUBSTR(PROCESSNAME, loc+1))) PROCESSNAME ,duration duration from ( select (e.endtime - b.starttime) * 1440 duration, to_char(b.starttime, 'hh24:mi:ss') starttime, to_char(e.endtime, 'hh24:mi:ss') endtime,  b.PROCESSNAME, instr(b.PROCESSNAME, ']') loc, b.infotype test_script from ( select processid, infodate starttime, PROCESSNAME, INFOMSG, INFOTYPE from etl_processinfo  where processid = (select max(PROCESSID) from etl_processinfo) and infotype = 'BEGIN' ) b  inner Join ( select processid, infodate endtime, PROCESSNAME, INFOMSG, INFOTYPE from etl_processinfo  where processid = (select max(PROCESSID) from etl_processinfo) and infotype = 'END' ) e on b.processid = e.processid  and b.PROCESSNAME = e.PROCESSNAME order by b.starttime)

• Checking form input data on submit with pure PHP [migrated]

  - by Leron

  I have some experience with PHP but I have never even try to do this wit pure PHP, but now a friend of mine asked me to help him with this task so I sat down and write some code. What I'm asking is for opinion if this is the right way to do this when you want to use only PHP and is there anything I can change to make the code better. Besides that I think the code is working at least with the few test I made with it. Here it is: <?php session_start(); // define variables and initialize with empty values $name = $address = $email = ""; $nameErr = $addrErr = $emailErr = ""; $_SESSION["name"] = $_SESSION["address"] = $_SESSION["email"] = ""; $_SESSION["first_page"] = false; if ($_SERVER["REQUEST_METHOD"] == "POST") { if (empty($_POST["name"])) { $nameErr = "Missing"; } else { $_SESSION["name"] = $_POST["name"]; $name = $_POST["name"]; } if (empty($_POST["address"])) { $addrErr = "Missing"; } else { $_SESSION["address"] = $_POST["address"]; $address = $_POST["address"]; } if (empty($_POST["email"])) { $emailErr = "Missing"; } else { $_SESSION["email"] = $_POST["email"]; $email = $_POST["email"]; } } if ($_SESSION["name"] != "" && $_SESSION["address"] != "" && $_SESSION["email"] != "") { $_SESSION["first_page"] = true; header('Location: http://localhost/formProcessing2.php'); //echo $_SESSION["name"]. " " .$_SESSION["address"]. " " .$_SESSION["email"]; } ?> <DCTYPE! html> <head> <style> .error { color: #FF0000; } </style> </head> <body> <form method="POST" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>"> Name <input type="text" name="name" value="<?php echo htmlspecialchars($name);?>"> <span class="error"><?php echo $nameErr;?></span> <br /> Address <input type="text" name="address" value="<?php echo htmlspecialchars($address);?>"> <span class="error"><?php echo $addrErr;?></span> <br /> Email <input type="text" name="email" value="<?php echo htmlspecialchars($email);?>"> <span class="error"><?php echo $emailErr;?></span> <br /> <input type="submit" name="submit" value="Submit"> </form> </body> </html>

• The Growing Importance of Network Virtualization

  - by user12608550

  The Growing Importance of Network Virtualization We often focus on server virtualization when we discuss cloud computing, but just as often we neglect to consider some of the critical implications of that technology. The ability to create virtual environments (or VEs [1]) means that we can create, destroy, activate and deactivate, and more importantly, MOVE them around within the cloud infrastructure. This elasticity and mobility has profound implications for how network services are defined, managed, and used to provide cloud services. It's not just servers that benefit from virtualization, it's the network as well. Network virtualization is becoming a hot topic, and not just for discussion but for companies like Oracle and others who have recently acquired net virtualization companies [2,3]. But even before this topic became so prominent, Solaris engineers were working on technologies in Solaris 11 to virtualize network services, known as Project Crossbow [4]. And why is network virtualization so important? Because old assumptions about network devices, topology, and management must be re-examined in light of the self-service, elasticity, and resource sharing requirements of cloud computing infrastructures. Static, hierarchical network designs, and inter-system traffic flows, need to be reconsidered and quite likely re-architected to take advantage of new features like virtual NICs and switches, bandwidth control, load balancing, and traffic isolation. For example, traditional multi-tier Web services (Web server, App server, DB server) that share net traffic over Ethernet wires can now be virtualized and hosted on shared-resource systems that communicate within a larger server at system bus speeds, increasing performance and reducing wired network traffic. And virtualized traffic flows can be monitored and adjusted as needed to optimize network performance for dynamically changing cloud workloads. Additionally, as VEs come and go and move around in the cloud, static network configuration methods cannot easily accommodate the routing and addressing flexibility that VE mobility implies; virtualizing the network itself is a requirement. Oracle Solaris 11 [5] includes key network virtualization technologies needed to implement cloud computing infrastructures. It includes features for the creation and management of virtual NICs and switches, and for the allocation and control of the traffic flows among VEs [6]. Additionally it allows for both sharing and dedication of hardware components to network tasks, such as allocating specific CPUs and vNICs to VEs, and even protocol-specific management of traffic. So, have a look at your current network topology and management practices in view of evolving cloud computing technologies. And don't simply duplicate the physical architecture of servers and connections in a virtualized environment…rethink the traffic flows among VEs and how they can be optimized using Oracle Solaris 11 and other Oracle products and services. [1] I use the term "virtual environment" or VE here instead of the more commonly used "virtual machine" or VM, because not all virtualized operating system environments are full OS kernels under the control of a hypervisor…in other words, not all VEs are VMs. In particular, VEs include Oracle Solaris zones, as well as SPARC VMs (previously called LDoms), and x86-based Solaris and Linux VMs running under hypervisors such as OEL, Xen, KVM, or VMware. [2] Oracle follows VMware into network virtualization space with Xsigo purchase; http://www.mercurynews.com/business/ci_21191001/oracle-follows-vmware-into-network-virtualization-space-xsigo [3] Oracle Buys Xsigo; http://www.oracle.com/us/corporate/press/1721421 [4] Oracle Solaris 11 Networking Virtualization Technology, http://www.oracle.com/technetwork/server-storage/solaris11/technologies/networkvirtualization-312278.html [5] Oracle Solaris 11; http://www.oracle.com/us/products/servers-storage/solaris/solaris11/overview/index.html [6] For example, the Solaris 11 'dladm' command can be used to limit the bandwidth of a virtual NIC, as follows: dladm create-vnic -l net0 -p maxbw=100M vnic0

• Cleaner ClientID's with ASP.NET 4.0

Our Interface Engineers want to be able to predict the ID’s of controls thereby having more control over their client side code for selecting/manipulating elements by ID or using CSS to target them. While playing with the just released VS2010 and .NET 4.0 I discovered some real cool improvements. One of them is the ability to now have full control over the ID being rendered for server controls. ASP.NET 4.0 controls now have a new ClientIDMode property which gives the developer complete control over the ID’s being rendered making it easy to write JavaScript and CSS against the rendered html. By default the ClientIDMode is set to Predictable which results in clean and predictable ID’s by concatenating the ID’s of the Parent and child controls. So the following markup: <asp:Content ID="ParentContainer" ContentPlaceHolderID="MainContentPlaceHolder" runat="server">     <asp:Label runat="server" ID="MyLabel">My Label</asp:Label> </asp:Content>                                                                                                                                                             Will render:   <span id="ParentContainer_MyLabel">My Label</span> Instead of something like this: (current) <span id="ct100_ParentContainer_MyLabel">My Label</span> Other modes include AutoID (renders ID’s like it currently does in .NET 3.5), Static (renders the ID exactly as specified in the code) and Inherit (defers the mode to the parent control). So now I can write my jQuery selector as: $(“ParentContainer_MyLabel”).text(“My new Text”); Instead of: $(‘<%=this. MyLabel.ClientID%>’).text(“My new Text”); Scott Mitchell has a great article about this new feature: http://bit.ly/ailEJ2 Am excited about this and some other improvements. Many thanks to the ASP.NET team for Listening!
