• ArchBeat Link-o-Rama for November 8, 2012

  - by Bob Rhubart

  Webcast: Meeting Customer Expectations in the New Age of Retail Keep your eye on this live webcast as Sanjeev Sharma (Principal Product Director, Oracle Exalogic), Kelly Goetsch (Senior Principal Product Manager, Oracle Commerce), and Dan Conway (Senior Product Manager, Oracle Retail) offer real-world examples of business value derived by running customer-facing applications on Oracle Engineered Systems. Live, Thursday Nov 8, 10am PT/ 1pm ET. Solving Big Problems in Our 21st Century Information Society | Irving Wladawsky-Berger "I believe that the kind of extensive collaboration between the private sector, academia and government represented by the Internet revolution will be the way we will generally tackle big problems in the 21st century. Just as with the Internet, governments have a major role to play as the catalyst for many of the big projects that the private sector will then take forward and exploit. The need for high bandwidth, robust national broadband infrastructures is but one such example." — Irving Wladawsky-Berger SOA Still Not Dead: Ratification of Governance Standard Highlights SOA’s Continued Relevance So just about the time I dig into Google Trends to learn that the conversation about governance peaked in 2004, along comes all this InfoQ article by Richard Seroter. And of course you've already listened to the OTN Archbeat Podcast about governance, right? Right? Implications of Java 6 End of Public Updates for Oracle E-Business Suite Users | Steven Chan The short version is: "Nothing will change for EBS users after February 2013." According to Steven Chan, "EBS users will continue to receive critical bug fixes and security fixes as well as general maintenance for Java SE 6." You'll find additional information on Steven's blog. ADF Mobile Custom Javascript – iFrame Injection | John Brunswick The ADF Mobile Framework provides a range of out of the box components to add within your AMX pages, according to John Brunswick. But what happens when "an out of the box component does not directly fulfill your development need? What options are available to extend your application interface?" John has an answer. How Data and BPM are married to get the right information to the right people at the right time | Leon Smiers "Business Process Management…supports a large group of stakeholders within an organization, all with different needs," says Oracle ACE Leon Smiers. "End-to-end processes typically run across departments, stakeholders and applications, and can often have a long life-span. So how do organizations provide all stakeholders with the information they need?" Leon provides answers in this post. Thought for the Day "(When) asking skilled architects…what they do when confronted with highly complex problems…(they) would most likely answer, 'Just use Common Sense.' (A) better expression than 'common sense' is 'contextual sense' — a knowledge of what is reasonable within a given content. Practicing architects through eduction, experience and examples accumulate a considerable body of contextual sense by the time they're entrusted with solving a system-level problem…" — Eberhardt Rechtin (January 16, 1926 – April 14, 2006) Source: SoftwareQuotes.com

• Key ATG architecture principles

  - by Glen Borkowski

  Overview The purpose of this article is to describe some of the important foundational concepts of ATG.  This is not intended to cover all areas of the ATG platform, just the most important subset - the ones that allow ATG to be extremely flexible, configurable, high performance, etc.  For more information on these topics, please see the online product manuals. Modules The first concept is called the 'ATG Module'.  Simply put, you can think of modules as the building blocks for ATG applications.  The ATG development team builds the out of the box product using modules (these are the 'out of the box' modules).  Then, when a customer is implementing their site, they build their own modules that sit 'on top' of the out of the box ATG modules.  Modules can be very simple - containing minimal definition, and perhaps a small amount of configuration.  Alternatively, a module can be rather complex - containing custom logic, database schema definitions, configuration, one or more web applications, etc.  Modules generally will have dependencies on other modules (the modules beneath it).  For example, the Commerce Reference Store module (CRS) requires the DCS (out of the box commerce) module. Modules have a ton of value because they provide a way to decouple a customers implementation from the out of the box ATG modules.  This allows for a much easier job when it comes time to upgrade the ATG platform.  Modules are also a very useful way to group functionality into a single package which can be leveraged across multiple ATG applications. One very important thing to understand about modules, or more accurately, ATG as a whole, is that when you start ATG, you tell it what module(s) you want to start.  One of the first things ATG does is to look through all the modules you specified, and for each one, determine a list of modules that are also required to start (based on each modules dependencies).  Once this final, ordered list is determined, ATG continues to boot up.  One of the outputs from the ordered list of modules is that each module can contain it's own classes and configuration.  During boot, the ordered list of modules drives the unified classpath and configpath.  This is what determines which classes override others, and which configuration overrides other configuration.  Think of it as a layered approach. The structure of a module is well defined.  It simply looks like a folder in a filesystem that has certain other folders and files within it.  Here is a list of items that can appear in a module: MyModule: META-INF - this is required, along with a file called MANIFEST.MF which describes certain properties of the module.  One important property is what other modules this module depends on. config - this is typically present in most modules.  It defines a tree structure (folders containing properties files, XML, etc) that maps to ATG components (these are described below). lib - this contains the classes (typically in jarred format) for any code defined in this module j2ee - this is where any web-apps would be stored. src - in case you want to include the source code for this module, it's standard practice to put it here sql - if your module requires any additions to the database schema, you should place that schema here Here's a screenshots of a module: Modules can also contain sub-modules.  A dot-notation is used when referring to these sub-modules (i.e. MyModule.Versioned, where Versioned is a sub-module of MyModule). Finally, it is important to completely understand how modules work if you are going to be able to leverage them effectively.  There are many different ways to design modules you want to create, some approaches are better than others, especially if you plan to share functionality between multiple different ATG applications. Components A component in ATG can be thought of as a single item that performs a certain set of related tasks.  An example could be a ProductViews component - used to store information about what products the current customer has viewed.  Components have properties (also called attributes).  The ProductViews component could have properties like lastProductViewed (stores the ID of the last product viewed) or productViewList (stores the ID's of products viewed in order of their being viewed).  The previous examples of component properties would typically also offer get and set methods used to retrieve and store the property values.  Components typically will also offer other types of useful methods aside from get and set.  In the ProductViewed component, we might want to offer a hasViewed method which will tell you if the customer has viewed a certain product or not. Components are organized in a tree like hierarchy called 'nucleus'.  Nucleus is used to locate and instantiate ATG Components.  So, when you create a new ATG component, it will be able to be found 'within' nucleus.  Nucleus allows ATG components to reference one another - this is how components are strung together to perform meaningful work.  It's also a mechanism to prevent redundant configuration - define it once and refer to it from everywhere. Here is a screenshot of a component in nucleus:  Components can be extremely simple (i.e. a single property with a get method), or can be rather complex offering many properties and methods.  To be an ATG component, a few things are required: a class - you can reference an existing out of the box class or you could write your own a properties file - this is used to define your component the above items must be located 'within' nucleus by placing them in the correct spot in your module's config folder Within the properties file, you will need to point to the class you want to use: $class=com.mycompany.myclass You may also want to define the scope of the class (request, session, or global): $scope=session In summary, ATG Components live in nucleus, generally have links to other components, and provide some meaningful type of work.  You can configure components as well as extend their functionality by writing code. Repositories Repositories (a.k.a. Data Anywhere Architecture) is the mechanism that ATG uses to access data primarily stored in relational databases, but also LDAP or other backend systems.  ATG applications are required to be very high performance, and data access is critical in that if not handled properly, it could create a bottleneck.  ATG's repository functionality has been around for a long time - it's proven to be extremely scalable.  Developers new to ATG need to understand how repositories work as this is a critical aspect of the ATG architecture.   Repositories essentially map relational tables to objects in ATG, as well as handle caching.  ATG defines many repositories out of the box (i.e. user profile, catalog, orders, etc), and this is comprised of both the underlying database schema along with the associated repository definition files (XML).  It is fully expected that implementations will extend / change the out of the box repository definitions, so there is a prescribed approach to doing this.  The first thing to be sure of is to encapsulate your repository definition additions / changes within your own module (as described above).  The other important best practice is to never modify the out of the box schema - in other words, don't add columns to existing ATG tables, just create your own new tables.  These will help ensure you can easily upgrade your application at a later date. xml-combination As mentioned earlier, when you start ATG, the order of the modules will determine the final configpath.  Files within this configpath are 'layered' such that modules on top can override configuration of modules below it.  This is the same concept for repository definition files.  If you want to add a few properties to the out of the box user profile, you simply need to create an XML file containing only your additions, and place it in the correct location in your module.  At boot time, your definition will be combined (hence the term xml-combination) with the lower, out of the box modules, with the result being a user profile that contains everything (out of the box, plus your additions).  Aside from just adding properties, there are also ways to remove and change properties. types of properties Aside from the normal 'database backed' properties, there are a few other interesting types: transient properties - these are properties that are in memory, but not backed by any database column.  These are useful for temporary storage. java-backed properties - by nature, these are transient, but in addition, when you access this property (by called the get method) instead of looking up a piece of data, it performs some logic and returns the results.  'Age' is a good example - if you're storing a birth date on the profile, but your business rules are defined in terms of someones age, you could create a simple java-backed property to look at the birth date and compare it to the current date, and return the persons age. derived properties - this is what allows for inheritance within the repository structure.  You could define a property at the category level, and have the product inherit it's value as well as override it.  This is useful for setting defaults, with the ability to override. caching There are a number of different caching modes which are useful at different times depending on the nature of the data being cached.  For example, the simple cache mode is useful for things like user profiles.  This is because the user profile will typically only be used on a single instance of ATG at one time.  Simple cache mode is also useful for read-only types of data such as the product catalog.  Locked cache mode is useful when you need to ensure that only one ATG instance writes to a particular item at a time - an example would be a customers order.  There are many options in terms of configuring caching which are outside the scope of this article - please refer to the product manuals for more details. Other important concepts - out of scope for this article There are a whole host of concepts that are very important pieces to the ATG platform, but are out of scope for this article.  Here's a brief description of some of them: formhandlers - these are ATG components that handle form submissions by users. pipelines - these are configurable chains of logic that are used for things like handling a request (request pipeline) or checking out an order. special kinds of repositories (versioned, files, secure, ...) - there are a couple different types of repositories that are used in various situations.  See the manuals for more information. web development - JSP/ DSP tag library - ATG provides a traditional approach to developing web applications by providing a tag library called the DSP library.  This library is used throughout your JSP pages to interact with all the ATG components. messaging - a message sub-system used as another way for components to interact. personalization - ability for business users to define a personalized user experience for customers.  See the other blog posts related to personalization.

• Need help with this question [closed]

  - by Jaime

  Occasionally, multiplying the sizes of nested loops can give an overestimate for the Big-Oh running time. This result happens when an innermost loop is infrequently executed. Give the Big-O analysis of the running time. Implement the following code and run for several values of N, and compare your analysis with the actual running times. for(int i = 1; i <= n; i++) for(int j = 1; j<=i * i; j++) if(j%i == 0) for(int k = 0; k < j; k++) sum++;

• Possible to use screen lock as timeout? [duplicate]

  - by Alex

  This question already has an answer here: Any app that tells me to take regular breaks from working? 3 answers What I'd like to do is lock the screen and have it wait a set amount of time (eg 20 mins) before it lets me log back in - so I make myself to have a break from the computer. Is it possible to do this? Thanks EDIT: Thanks for the suggestions - but I don't actually want something to remind me to take scheduled breaks. More something I can click when I realise I'm getting distracted and it'll immediately lock the screen for a fixed amount of time. Or even just lock screen if I can find a way to stop it letting me log in for 20 mins or so.

• Emailing Interviewer after interview regarding technical solution

  - by Raghav Shankar

  I had an interview yesterday where I was given a programming problem and I was asked to figure the optimal solution for it. I gave a solution that worked in linear time, but used 2 loops (not inner loops). At the end of the interview, the interviewer saw I was interested in solving the problem, so he said the optimal solution uses only one loop and has linear complexity and at the end of the interview I had asked for his card and he gave one to me. I think I might have figured out a solution and I was wondering if it's alright to email the recruiter thanking him for his time and also mentioning about the solution I had figured out?

• A rather long question about installation/uninstall

  - by user2364312

  Ok so here's the deal guys, last week I decided I want to install Ubunutu again because I really missed it. (Last time I had an ubunutu was 7.somehting) I downloaded 12.04 and isntalled it via bootable usb device. Knowing how dual boots works I cleared up some space on my hard disc before hand using the windows 7 built in disc manager. During Ubunutu's installation I thought that by choosing "Install Ubuntu alongside Windows 7" will automatically just use the space I cleared before, but apperentaly it did not since that partition is still 100% free space. On what partition is Ubunutu installed when using that method? And how can I uninstall it to re-install it back on the space I cleared up for it? Thank you very your time reading and helping!

• Exit Infragistics, Enter Telerik

  - by Anthony Trudeau

  Today I made the purchase of the Premium Collection of components from Telerik.  This follows an evaluation I’ve been doing to replace the Infragistics components we currently use for Windows Forms, ASP.NET MVC, and WPF. It was not a formal evaluation.  I had already decided to move the company away from Infragistics.  That decision was mostly born out of frustration with support over using the Infragistics components in my first production MVC application. One such issue was a simple scenario where you have a model that has a scalar property that can be one value out of a list.  The built-in combobox does this, but I was told by Infragistics support that they didn’t support it – and it took them several emails and days of waiting between responses to determine that.  I implemented this in Telerik in a minute not including the several minutes it took me to get a rudimentary understanding for the component and its API. Here’s the code using the built-in combobox:@Html.DropDownListFor(x => x.VendorId, new SelectList(ViewBag.Vendors, "VendorId", "VendorName", Model.VendorId), "Select Id") Here’s the code using the Telerik combobox:@(Html.Telerik().ComboBoxFor(model => model.VendorId) .AutoFill(true) .BindTo(new SelectList(ViewBag.Vendors, "VendorId", "VendorName", Model.VendorId)) )   I chose Telerik over other competitors based on the professional appearance of their website, and how easy it was to find information.  I’d like to say I had time to evaluate other Infragistics competitors.  Due to time constraints I had to make an initial decision based on superficial, but still important things. I picked Telerik with the plan to only look further at other companies if my evaluation didn’t meet my expectations.  Luckily they did, because I didn’t relish the thought of carving out more time to evaluate another set of components. Overall my experience with Telerik has been superior to Infragistics in every way.  The installation was easy using their control panel installer application.  Getting up to speed has been easy.  And the communication from Telerik has met my expectations.  And we’ll continue to be good as long as I don’t start getting email messages from a sales rep saying that they want to talk to me about training and consulting – I’m looking at you Infragistics.

• What was the first consumer-oriented hardware/software solution?

  - by Maksee

  We all know the story of the personal computer as a consumer-oriented product. But I just thought that real end user solution should have appeared before that time. So a product that was probably expensive, but allowed using it as a service charging for it, for example computer-terminal for transport time-table access or game machine. On the other site, the video terminals as we know them appeared not so long ago. So if there was something like this, this could be hardware/software most likely offering no interactivity, but probably printing some information based on user actions.

• E.T. Phone "Home" - Hey I've discovered a leak..!

  - by Martin Deh

  Being a member of the WebCenter ATEAM, we are often asked to performance tune a WebCenter custom portal application or a WebCenter Spaces deployment.  Most of the time, the process is pretty much the same.  For example, we often use tools like httpWatch and FireBug to monitor the application, and then perform load tests using JMeter or Selenium.  In addition, there are the fine tuning of the different performance based tuning parameters that are outlined in the documentation and by blogs that have been written by my fellow ATEAMers (click on the "performance" tag in this ATEAM blog).  While performing the load test where the outcome produces a significant reduction in the systems resources (memory), one of the causes that plays a role in memory "leakage" is due to the implementation of the navigation menu UI.  OOTB in both JDeveloper and WebCenter Spaces, there are sample (page) templates that include a "default" navigation menu.  In WebCenter Spaces, this is through the SpacesNavigationModel taskflow region, and in a custom portal (i.e. pageTemplate_globe.jspx) the menu UI is contructed using standard ADF components.  These sample menu UI's basically enable the underlying navigation model to visualize itself to some extent.  However, due to certain limitations of these sample menu implementations (i.e. deeper sub-level of navigations items, look-n-feel, .etc), many customers have developed their own custom navigation menus using a combination of HTML, CSS and JQuery.  While this is supported somewhat by the framework, it is important to know what are some of the best practices in ensuring that the navigation menu does not leak.  In addition, in this blog I will point out a leak (BUG) that is in the sample templates.  OK, E.T. the suspence is killing me, what is this leak? Note: for those who don't know, info on E.T. can be found here In both of the included templates, the example given for handling the navigation back to the "Home" page, will essentially provide a nice little memory leak every time the link is clicked. Let's take a look a simple example, which uses the default template in Spaces. The outlined section below is the "link", which is used to enable a user to navigation back quickly to the Group Space Home page. When you (mouse) hover over the link, the browser displays the target URL. From looking initially at the proposed URL, this is the intended destination.  Note: "home" in this case is the navigation model reference (id), that enables the display of the "pretty URL". Next, notice the current URL, which is displayed in the browser.  Remember, that PortalSiteHome = home.  The other highlighted item adf.ctrl-state, is very important to the framework.  This item is basically a persistent query parameter, which is used by the (ADF) framework to managing the current session and page instance.  Without this parameter present, among other things, the browser back-button navigation will fail.  In this example, the value for this parameter is currently 95K25i7dd_4.  Next, through the navigation menu item, I will click on the Page2 link. Inspecting the URL again, I can see that it reports that indeed the navigation is successful and the adf.ctrl-state is also in the URL.  For those that are wondering why the URL displays Page3.jspx, instead of Page2.jspx. Basically the (file) naming convention for pages created ar runtime in Spaces start at Page1, and then increment as you create additional pages.  The name of the actual link (i.e. Page2) is the page "title" attribute.  So the moral of the story is, unlike design time created pages, run time created pages the name of the file will 99% never match the name that appears in the link. Next, is to click on the quick link for navigating back to the Home page. Quick investigation yields that the navigation was indeed successful.  In the browser's URL there is a home (pretty URL) reference, and there is also a reference to the adf.ctrl-state parameter.  So what's the issue?  Can you remember what the value was for the adf.ctrl-state?  The current value is 3D95k25i7dd_149.  However, the previous value was 95k25i7dd_4.  Here is what happened.  Remember when (mouse) hovering over the link produced the following target URL: http://localhost:8888/webcenter/spaces/NavigationTest/home This is great for the browser as this URL will navigate to the intended targer.  However, what is missing is the adf.ctrl-state parameter.  Since this parameter was not present upon navigation "within" the framework, the ADF framework produced another adf.ctrl-state (object).  The previous adf.ctrl-state basically is orphaned while continuing to be alive in memory.  Note: the auto-creation of the adf.ctrl state does happen initially when you invoke the Spaces application  for the first time.  The following is the line of code which produced the issue: <af:goLink destination="#{boilerBean.globalLogoURIInSpace} ... Here the boilerBean is responsible for returning the "string" url, which in this case is /spaces/NavigationTest/home. Unfortunately, again what is missing is adf.ctrl-state. Note: there are more than one instance of the goLinks in the sample templates. So E.T. how can I correct this? There are 2 simple fixes.  For the goLink's destination, use the navigation model to return the actually "node" value, then use the goLinkPrettyUrl method to add the current adf.ctrl-state: <af:goLink destination="#{navigationContext.defaultNavigationModel.node['home'].goLinkPrettyUrl}"} ... />  Note: the node value is the [navigation model id]  Using a goLink does solve the main issue.  However, since the link basically does a redirect, some browsers like IE will produce a somewhat significant "flash".  In a Spaces application, this may be an annoyance to the users.  Another way to solve the leakage problem, and also remove the flash between navigations is to use a af:commandLink.  For example, here is the code example for this scenario: <af:commandLink id="pt_cl2asf" actionListener="#{navigationContext.processAction}" action="pprnav">    <f:attribute name="node" value="#{navigationContext.defaultNavigationModel.node['home']}"/> </af:commandLink> Here, the navigation node to where home is located is delivered by way of the attribute to the commandLink.  The actual navigation is performed by the processAction, which is needing the "node" value. E.T. OK, you solved the OOTB sample BUG, what about my custom navigation code? I have seen many implementations of creating a navigation menu through custom code.  In addition, there are some blog sites that also give detailed examples.  The majority of these implementations are very similar.  The code usually involves using standard HTML tags (i.e. DIVS, UL, LI, .,etc) and either CSS or JavaScript (JQuery) to produce the flyout/drop-down effect.  The navigation links in these cases are standard <a href... > tags.  Although, this type of approach is not fully accepted by the ADF community, it does work.  The important thing to note here is that the <a> tag value must use the goLinkPrettyURL method of contructing the target URL.  For example: <a href="${contextRoot}${menu.goLinkPrettyUrl}"> The main reason why this type of approach is popular is that links that are created this way (also with using af:goLinks), the pages become crawlable by search engines.  CommandLinks are currently not search friendly.  However, in the case of a Spaces instance this may be acceptable.  So in this use-case, af:commandLinks, which would replace the <a>  (or goLink) tags. The example code given of the af:commandLink above is still valid. One last important item.  If you choose to use af:commandLinks, special attention must be given to the scenario in which java script has been used to produce the flyout effect in the custom menu UI.  In many cases that I have seen, the commandLink can only be invoked once, since there is a conflict between the custom java script with the ADF frameworks own scripting to control the view.  The recommendation here, would be to use a pure CSS approach to acheive the dropdown effects. One very important thing to note.  Due to another BUG, the WebCenter environement must be patched to BP3 (patch  p14076906).  Otherwise the leak is still present using the goLinkPrettyUrl method.  Thanks E.T.!  Now I can phone home and not worry about my application running out of resources due to my custom navigation!

• Stop YouTube Videos from Automatically Playing in Chrome

  - by The Geek

  If you’ve actually used the internet before, you’ve probably come across a page with an auto-playing YouTube clip, and chances are good it was a rather annoying one. Here’s how to stop them from starting automatically in Chrome. We’ve already told you how to stop them from automatically playing if you’re a Firefox user (best answer: use Flashblock!), but now it’s time for Chrome users to get their turn. Use the Stop Autoplay for YouTube Extension The great thing about this extension is that it stops the video from playing, but it allows it to continue buffering, so when you do feel like playing the video, it’ll already be downloaded—really useful for people with slower internet connections. There’s no UI or anything fancy, just head to the extension page and click the Install button. If you want to get rid of it later, use the Tools –> Extensions menu (or you can type chrome://extensions/ into your address bar), and then click the Uninstall link for that add-on.   Download Stop Autoplay for YouTube [Google Chrome Extensions] Using FlashBlock for Chrome If you really wanted to, you could just disable Flash across the board using FlashBlock for Chrome. Once you’ve installed the extension, you won’t see any Flash elements anywhere, and you’ll have to move your mouse over them and click to enable them each time. When I installed the extension the first time, I noticed that YouTube was already in the allow list. I’m not sure if that’s the default setting or not, but you can use the icon in the address bar, or the Options from the Extensions panel to get to the settings page, and from there you can remove anything from the White List that you wouldn’t want. Another nice feature about Flash Block is that it can also block Silverlight, or you could simply uninstall or remove unnecessary Chrome plug-ins.

• Updates about Multidimensional vs Tabular #ssas #msbi

  - by Marco Russo (SQLBI)

  I recently read the blog post from James Serra Tabular model: Not ready for prime time? (read also the comments because there are discussions about a few points raised by James) and the following post from Christian Wade Multidimensional or Tabular. In the last 2 years I worked with many companies adopting Tabular in different scenarios and I agree with some of the points expressed by James in his post (especially about missing features in Tabular if compared to Multidimensional), but I strongly disagree in others. In general, Tabular is a good choice for a new project when: the development team does not have a good knowledge of Multidimensional and MDX (DAX is faster to learn, not so easy as it is sold by MS, but definitely easier than MDX) you don’t need calculations based on hierarchies (common in certain financial applications, but not so common as it could seem) there are important calculations based on distinct count measures there are complex calculations based on many-to-many relationships Until now, I never suggested to migrate an existing Multidimensional model to a Tabular one. There should be very important reasons for that, such as performance issues in distinct count and many-to-many relationships that cannot be easily solved by optimizing the Multidimensional model, but I still never encountered this scenario. I would say that in 80% of the new projects, you might use either Multidimensional or Tabular and the real difference is the time-to-market depending on the skills of the development team. So it’s not strange that who is used to Multidimensional is not moving to Tabular, not getting a particular benefit from the new model unless specific requirements exist. The recent DAXMD feature that allows using SharePoint Power View on Multidimensional is a really important one, even if I’d like having also Excel Power View enabled for this scenario (this should be just a question of time). Another scenario in which I’m seeing a growing adoption of Tabular is in companies that creates models for their product/service and do that by using XMLA or Tabular AMO 2012. I am used to call them ISVs, even if those providing services cannot be really defined in this way. These companies are facing the multitenancy challenge with Tabular and even if this is a niche market, I see some potential here, because adopting Tabular seems a much more natural choice than Multidimensional in those scenario where an analytical engine has to be embedded to deliver one of the features of a larger product/service delivered to customers. I’d like to see other feedbacks in the comments: tell your story of choosing between Tabular and Multidimensional in a BI project you started with SQL Server 2012, thanks!

• Log Blog

  - by PointsToShare

  © 2011 By: Dov Trietsch. All rights reserved Logging – A log blog In a another blog (Missing Fields and Defaults) I spoke about not doing a blog about log files, but then I looked at it again and realized that this is a nice opportunity to show a simple yet powerful tool and also deal with static variables and functions in C#. My log had to be able to answer a few simple logging rules:   To log or not to log? That is the question – Always log! That is the answer  Do we share a log? Even when a file is opened with a minimal lock, it does not share well and performance greatly suffers. So sharing a log is not a good idea. Also, when sharing, it is harder to find your particular entries and you have to establish rules about retention. My recommendation – Do Not Share!  How verbose? Your log can be very verbose – a good thing when testing, very terse – a good thing in day-to-day runs, or somewhere in between. You must be the judge. In my Blog, I elect to always report a run with start and end times, and always report errors. I normally use 5 levels of logging: 4 – write all, 3 – write more, 2 – write some, 1 – write errors and timing, 0 – write none. The code sample below is more general than that. It uses the config file to set the max log level and each call to the log assigns a level to the call itself. If the level is above the .config highest level, the line will not be written. Programmers decide which log belongs to which level and thus we can set the .config differently for production and testing.  Where do I keep the log? If your career is important to you, discuss this with the boss and with the system admin. We keep logs in the L: drive of our server and make sure that we have a directory for each app that needs a log. When adding a new app, add a new directory. The default location for the log is also found in the .config file Print One or Many? There are two options here:   1.     Print many, Open but once once – you start the stream and close it only when the program ends. This is what you can do when you perform in “batch” mode like in a console app or a stsadm extension.The advantage to this is that starting a closing a stream is expensive and time consuming and because we use a unique file, keeping it open for a long time does not cause contention problems. 2.     Print one entry at a time or Open many – every time you write a line, you start the stream, write to it and close it. This work for event receivers, feature receivers, and web parts. Here scalability requires us to create objects on the fly and get rid of them as soon as possible.  A default value of the onceOrMany resides in the .config.  All of the above applies to any windows or web application, not just SharePoint.  So as usual, here is a routine that does it all, and a few simple functions that call it for a variety of purposes.   So without further ado, here is app.config  <?xml version="1.0" encoding="utf-8" ?> <configuration>     <configSections>         <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, ublicKeyToken=b77a5c561934e089" >         <section name="statics.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />         </sectionGroup>     </configSections>     <applicationSettings>         <statics.Properties.Settings>             <setting name="oneOrMany" serializeAs="String">                 <value>False</value>             </setting>             <setting name="logURI" serializeAs="String">                 <value>C:\staticLog.txt</value>             </setting>             <setting name="highestLevel" serializeAs="String">                 <value>2</value>             </setting>         </statics.Properties.Settings>     </applicationSettings> </configuration>   And now the code:  In order to persist the variables between calls and also to be able to persist (or not to persist) the log file itself, I created an EventLog class with static variables and functions. Static functions do not need an instance of the class in order to work. If you ever wondered why our Main function is static, the answer is that something needs to run before instantiation so that other objects may be instantiated, and this is what the “static” Main does. The various logging functions and variables are created as static because they do not need instantiation and as a fringe benefit they remain un-destroyed between calls. The Main function here is just used for testing. Note that it does not instantiate anything, just uses the log functions. This is possible because the functions are static. Also note that the function calls are of the form: Class.Function.  using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; namespace statics {       class Program     {         static void Main(string[] args)         {             //write a single line             EventLog.LogEvents("ha ha", 3, "C:\\hahafile.txt", 4, true, false);             //this single line will not be written because the msgLevel is too high             EventLog.LogEvents("baba", 3, "C:\\babafile.txt", 2, true, false);             //The next 4 lines will be written in succession - no closing             EventLog.LogLine("blah blah", 1);             EventLog.LogLine("da da", 1);             EventLog.LogLine("ma ma", 1);             EventLog.LogLine("lah lah", 1);             EventLog.CloseLog(); // log will close             //now with specific functions             EventLog.LogSingleLine("one line", 1);             //this is just a test, the log is already closed             EventLog.CloseLog();         }     }     public class EventLog     {         public static string logURI = Properties.Settings.Default.logURI;         public static bool isOneLine = Properties.Settings.Default.oneOrMany;         public static bool isOpen = false;         public static int highestLevel = Properties.Settings.Default.highestLevel;         public static StreamWriter sw;         /// <summary>         /// the program will "print" the msg into the log         /// unless msgLevel is > msgLimit         /// onceOrMany is true when once - the program will open the log         /// print the msg and close the log.

• Android - Rendering HUD View to SurfaceView

  - by Jon

  I have developed a relatively simple game in android, to get my head around it all, and on the back of it developed a crude game engine (in the loosest sense!). I use a SurfaceView and canvas (no OpenGL) - I'll cross that bridge another time! I have implemented a game HUD, title screens etc. by overlaying standard Android view widgets over my SurfaceView. This all works reasonably well maintaining an acceptable frame-rate, but it is a simple game with not a lot happening on or off screen. What I am wondering now is whether one could (and whether one would get any advantage by) drawing all my views to the one SurfaceView, all controlled by the main game thread. At the moment I have handlers flinging messages around and runOnUiThreads here, there and everywhere. Quite cumbersome. Any thoughts on this would be much appreciated (before I perhaps waste time trying to do it!)

• How do you update copyright notices?

  - by James

  So now it's 2011, and as I carry on coding on our active projects it's time to update some copyright notices. eg. Copyright Widgets Ltd 2010 to Copyright Widgets Ltd 2010, 2011 My question is when do you update the copyright notices? Do you change the notice in the head of a file the first time you work on that file? Since a module is one piece of code consisting of many files that work together, do you update all notices in that module when you change a single file in that module? Since a program is one piece of code (maybe consisting of many modules), do you update all notices in that program when you change a single file in that program? Or do you just go through and change en-mass over your morning coffee on the grounds your about to start programming and updateing things?

• The best Windows 7 virtual desktop tool by far&hellip; Dexpot

  - by Eric Nelson

  [Oh – and Windows XP, Vista etc] Every so often I yearn for the virtual desktop functionality that is implemented so well under Linux. Unfortunately every time I start looking for a great tool for Windows I ultimately end up disappointed. But … I think this time around I have actually found one that will outlast the first day or two and become a must have. Check out http://www.dexpot.de/ So far this is 100% stable, 100% sensible and offers awesome functionality, yet still is very simple to use. There is a detailed look at the many features on the site but a couple that do it for me: Desktop Manager and next/previous tray icons make it easy to navigate around: Announcement of Desktop as a desktop takes focus: And best of all, Windows 7 preview integration And… it is FREE for private use and you get 30 days to try it out for professional use (e.g. me)

• 2 min video about the SQL_Compare

  - by CatherineRussell

  It is nice to start blogging again! I am working on new project in a small company now. We do not have a full time database admin. I have to cover multiple roles: getting requirements, writing docs and creating diagrams, designing app, writing code, testing and DBA role. I am not a DBA. But, I have to do day to day database changes: adding new new columns and tables. Check out 2 min video about the SQL_Compare. This tool saves time by automatically comparing and synchronizing database schemas; eliminate mistakes migrating database changes from dev, to test, to production; speed up the deployment of new database schema updates; generate T-SQL scripts to update one database to match the schema of another; find and fix errors caused by differences between databases;  keeps an accurate history of all previous database records.  http://www.red-gate.com/products/SQL_Compare/index.htm

• Why did ctrl-f stop working in LibreOffice?

  - by amandabee

  I've basically settled into Unity, but one constant that is kind of giving me agita is that in LibreOffice Calc (and Writer) ctrl-f does nothing. I can go to edit > find ... and the edit menu even suggests ctrl-f as a keyboard shortcut, but actually typing it doesn't do anything. ctrl-alt-f works fine. The only thing that doesn't work is ctrl-f. I had a really hard time getting settled with Unity (mostly trying to get my old Gnome-do and Compiz settings back) so I spent a lot of time monkeying with the Compiz Settings Manager. But I can't figure out where I would have unset/ overrode this. Plus, it isn't like ctrl-f does something unexpected. It just does nothing.

• How long can a user remember what they were working on? [migrated]

  - by GlenPeterson

  A web application lets the user browse its screens for future or past months. The time period the user is currently viewing follows the user through every screen of the system. But users can be logged in for a month or more. After a certain period of inactivity, we will prompt the user: You were viewing November 2008 when you last clicked. Want to view the current (default) time period instead? How long between user clicks should we wait to show this message? I'm guessing somewhere between 30 minutes and 3 hours most people will forget what they were doing, but I'd love to have some data, or someone's experience to base it on. Other suggestions related to this issue?

• A question every programmer has. Maybe.

  - by zengr

  I have been using Java from the last 2yrs (academics). Now, when I am graduating, I received a job offer from a .com. The job is awesome and it's a backend Java work. I wanted to get involved with Ruby on Rails, looked for alot of jobs, gave few interviews, but didn't make it. So, what should I do now? Should I go ahead with Java and learn/do more with Java, a complete 360degree of the java world - Full stack of Java from backend to frontend? OR Java at workplace and try to improve my Ruby on Rails. I understand, this is a very subjective question and depends on the individual, but what would you have done? Have you ever faced a similar problem? I feel I have wasted some time with Rails, where I could not "conquer" Rails, where as I could have used that time to go more into Java.

• Switching between ethernet interfaces on Ubuntu 10.04 SERVER

  - by Chaitanya

  I have ubuntu 10.04 "SERVER" installed on a system with two ehternet ports. I use only one at a time. I wanted to know if I can switch between ports without using ifup and ifdown every time. That means when I connect my Lan cable on eth0 it should work and it does. But when I disconnect the lan cable and connect it on eth1 I have to ifdown eth0 and only then it works. In my /etc/network/interfaces file I have configured both eth0 and eth1. there is no problem other than I have to switch it manually with ifdown and ifup everytime. Please guide. Thanks in advance
