• Catching people up

  - by Randy Walker

  It’s been a while since I’ve blogged.  I suppose sometimes when one’s personal life gets busy, there are some things that fall by the wayside.  So what all has happened since I last blogged? Business has been good with lots of lessons learned.  I had hoped I would have had an important announcement several months ago concerning the business I own, but that simply hasn’t materialized yet. Will keep everyone posted.  Ensuring your business has a good sales pipeline and stays ahead in the technology curve is extremely important. I eventually resigned my INETA Board of Directors position.  Never one to mince words, frankly I had several issues with how things are run at INETA.  Mostly centered around some ethical issues compounded by higher expectations and what I felt was a lack of support.  I had put my hat into the ring in order to help change things, but eventually I didn’t really see change a possibility, and so all things must come to an end. I have started writing up a new business plan for a new startup, details to be forthcoming.  It’s new name will be Linker CRM.  I have some aggressive game changing plans ahead for it.  Ping me if you’re interested in finding out more information and don’t mind signing a non-compete and confidentiality agreement. ;) My personal life, has been hectic.  A 4 year old will do that to you.  As well as being divorced and the headaches associated with that.  If you’ve been divorced, I feel your pain, if you haven’t been, I would never wish the emotional roller coaster ride on anyone.  Dating has been interesting.  It’s a lot different at age 35 than your early 20s and relationships are far more complicated. Ethan is an absolutely fantastic adorable charmer of a kid.  He’s definitely going to be a heartbreaker.  His personality is really shining through and he’s taken onto my appreciation of music (and yes I’ll admit dance too).  We watched America’s Best Dance Crew (ABDC) together for the first time, he really loved it and I think he’ll probably start his own break dancing crew eventually.  I’ve posted a few videos on Facebook for those interested.  I’m extremely proud of him, but please say a little prayer for us as we try and continue to curb some behavior issues, as well as his mother and I try to settle some differences. This year’s travel plans have already included Dallas, Seattle, and a trip to Vancouver for the 2010 Olympics (a huge thanks to the Washington State Police for the nice souvenir they gave me).  Future travel plans include a trip to Korea in the 2nd half of May, Nashville again in the summer, and hopefully New Orleans for the Microsoft TechEd 2010 Conference. Look for some new blog posts soon …

• SQL SERVER – Index Created on View not Used Often – Observation of the View – Part 2

  - by pinaldave

  Earlier, I have written an article about SQL SERVER – Index Created on View not Used Often – Observation of the View. I received an email from one of the readers, asking if there would no problems when we create the Index on the base table. Well, we need to discuss this situation in two different cases. Before proceeding to the discussion, I strongly suggest you read my earlier articles. To avoid the duplication, I am not going to repeat the code and explanation over here. In all the earlier cases, I have explained in detail how Index created on the View is not utilized. SQL SERVER – Index Created on View not Used Often – Limitation of the View 12 SQL SERVER – Index Created on View not Used Often – Observation of the View SQL SERVER – Indexed View always Use Index on Table As per earlier blog posts, so far we have done the following: Create a Table Create a View Create Index On View Write SELECT with ORDER BY on View However, the blog reader who emailed me suggests the extension of the said logic, which is as follows: Create a Table Create a View Create Index On View Write SELECT with ORDER BY on View Create Index on the Base Table Write SELECT with ORDER BY on View After doing the last two steps, the question is “Will the query on the View utilize the Index on the View, or will it still use the Index of the base table?“ Let us first run the Create example. USE tempdb GO IF EXISTS (SELECT * FROM sys.views WHERE OBJECT_ID = OBJECT_ID(N'[dbo].[SampleView]')) DROP VIEW [dbo].[SampleView] GO IF EXISTS (SELECT * FROM sys.objects WHERE OBJECT_ID = OBJECT_ID(N'[dbo].[mySampleTable]') AND TYPE IN (N'U')) DROP TABLE [dbo].[mySampleTable] GO -- Create SampleTable CREATE TABLE mySampleTable (ID1 INT, ID2 INT, SomeData VARCHAR(100)) INSERT INTO mySampleTable (ID1,ID2,SomeData) SELECT TOP 100000 ROW_NUMBER() OVER (ORDER BY o1.name), ROW_NUMBER() OVER (ORDER BY o2.name), o2.name FROM sys.all_objects o1 CROSS JOIN sys.all_objects o2 GO -- Create View CREATE VIEW SampleView WITH SCHEMABINDING AS SELECT ID1,ID2,SomeData FROM dbo.mySampleTable GO -- Create Index on View CREATE UNIQUE CLUSTERED INDEX [IX_ViewSample] ON [dbo].[SampleView] ( ID2 ASC ) GO -- Select from view SELECT ID1,ID2,SomeData FROM SampleView ORDER BY ID2 GO -- Create Index on Original Table -- On Column ID1 CREATE UNIQUE CLUSTERED INDEX [IX_OriginalTable] ON mySampleTable ( ID1 ASC ) GO -- On Column ID2 CREATE UNIQUE NONCLUSTERED INDEX [IX_OriginalTable_ID2] ON mySampleTable ( ID2 ) GO -- Select from view SELECT ID1,ID2,SomeData FROM SampleView ORDER BY ID2 GO Now let us see the execution plans for both of the SELECT statement. Before Index on Base Table (with Index on View): After Index on Base Table (with Index on View): Looking at both executions, it is very clear that with or without, the View is using Indexes. Alright, I have written 11 disadvantages of the Views. Now I have written one case where the View is using Indexes. Anybody who says that I am being harsh on Views can say now that I found one place where Index on View can be helpful.

• [MISC GEEKERY] Lucid Lynx to Come Loaded with Ubuntu One Music Store

  - by Vivek

  Ubuntu 10.04 (code name Lucid Lynx) will come loaded with the Ubuntu One music store. Rhythmbox will have the Ubuntu One music store integrated in it. It’ll also allow users to download purchased music to their local machine. Ubuntu One Music Store Users will be able to access Ubuntu One music store from the sidebar of Rhythmbox. The music store is a web page that opens in the Rhythmbox player. There are albums listed on the home page of the Ubuntu One music store page. Ubuntu One music store is powered by 7digital, which is a leading digital B2B media delivery company based in London and operating globally. Canonical, the company behind Ubuntu, has partnered with 7digital to bring the music store to it’s users, integrating it with Rhythmbox and it’s cloud storage service UbuntuOne which was launched last year. The home screen of the Ubuntu One music store displays popular albums and functionality to browse and search. You can search for Artists, Tracks, Albums, or a combination of all three. Users will also be able to browse the store alphabetically, or based on different music genres. Once you select a specific artist, all their available albums are arranged in a grid. Once an album is selected, you’ll will be able to download specific songs or the whole album. You’ll also be allowed to preview different songs for 60 seconds. You’ll be able to buy tracks using a credit card or with PayPal. The purchased tracks will be visible under Library \ Purchased from Ubuntu One. The downloaded tracks are also synced with your UbuntuOne account. This means that you’ll be able to access your tracks from any where on the web. The default UbuntuOne account comes with 2 GB free storage, however, you can also purchase additional space if you need it.   All the music is in mp3 format which is not supported by default in Ubuntu. However, you can get mp3 playback functionality using GStreamer multimedia framework. Conclusion All in all the Ubuntu One music store is a positive move to enhance the user experience and also increase the popularity of Canonical in bringing Ubuntu closer to regular users. This would also provide Canonical to make some revenue in collaboration with 7digital.

• Don&rsquo;t Forget! In-Memory Databases are Hot

  - by andrewbrust

  If you’re left scratching your head over SAP’s intention to acquire Sybase for almost $6 million, you’re not alone.  Despite Sybase’s 1990s reign as the supreme database standard in certain sectors (including Wall Street), the company’s flagship product has certainly fallen from grace.  Why would SAP pay a greater than 50% premium over Sybase’s closing price on the day of the announcement just to acquire a relational database which is firmly stuck in maintenance mode? Well there’s more to Sybase than the relational database product.  Take, for example, its mobile application platform.  It hit Gartner’s “Leaders’ Quadrant” in January of last year, and SAP needs a good mobile play.  Beyond the platform itself, Sybase has a slew of mobile services; click this link to look them over. There’s a second major asset that Sybase has though, and I wonder if it figured prominently into SAP’s bid: Sybase IQ.  Sybase IQ is a columnar database.  Columnar databases place values from a given database column contiguously, unlike conventional relational databases, which store all of a row’s data in close proximity.  Storing column values together works well in aggregation reporting scenarios, because the figures to be aggregated can be scanned in one efficient step.  It also makes for high rates of compression because values from a single column tend to be close to each other in magnitude and may contain long sequences of repeating values.  Highly compressible databases use much less disk storage and can be largely or wholly loaded into memory, resulting in lighting fast query performance.  For an ERP company like SAP, with its own legacy BI platform (SAP BW) and the entire range of Business Objects and Crystal Reports BI products (which it acquired in 2007) query performance is extremely important. And it’s a competitive necessity too.  QlikTech has built an entire company on a columnar, in-memory BI product (QlikView).  So too has startup company Vertica.  IBM’s TM1 product has been doing in-memory OLAP for years.  And guess who else has the in-memory religion?  Microsoft does, in the form of its new PowerPivot product.  I expect the technology in PowerPivot to become strategic to the full-blown SQL Server Analysis Services product and the entire Microsoft BI stack.  I sure don’t blame SAP for jumping on the in-memory bandwagon, if indeed the Sybase acquisition is, at least in part, motivated by that. It will be interesting to watch and see what SAP does with Sybase’s product line-up (assuming the acquisition closes), including the core database, the mobile platform, IQ, and even tools like PowerBuilder.  It is also fascinating to watch columnar’s encroachment on relational.  Perhaps this acquisition will be columnar’s tipping point and people will no longer see it as a fad.  Are you listening Larry Ellison?

• NoSQL with RavenDB and ASP.NET MVC - Part 2

  - by shiju

  In my previous post, we have discussed on how to work with RavenDB document database in an ASP.NET MVC application. We have setup RavenDB for our ASP.NET MVC application and did basic CRUD operations against a simple domain entity. In this post, let’s discuss on domain entity with deep object graph and how to query against RavenDB documents using Indexes.Let's create two domain entities for our demo ASP.NET MVC appplication  public class Category {       public string Id { get; set; }     [Required(ErrorMessage = "Name Required")]     [StringLength(25, ErrorMessage = "Must be less than 25 characters")]     public string Name { get; set;}     public string Description { get; set; }     public List<Expense> Expenses { get; set; }       public Category()     {         Expenses = new List<Expense>();     } }    public class Expense {       public string Id { get; set; }     public Category Category { get; set; }     public string  Transaction { get; set; }     public DateTime Date { get; set; }     public double Amount { get; set; }   }  We have two domain entities - Category and Expense. A single category contains a list of expense transactions and every expense transaction should have a Category.Let's create  ASP.NET MVC view model  for Expense transaction public class ExpenseViewModel {     public string Id { get; set; }       public string CategoryId { get; set; }       [Required(ErrorMessage = "Transaction Required")]            public string Transaction { get; set; }       [Required(ErrorMessage = "Date Required")]            public DateTime Date { get; set; }       [Required(ErrorMessage = "Amount Required")]     public double Amount { get; set; }       public IEnumerable<SelectListItem> Category { get; set; } } Let's create a contract type for Expense Repository  public interface IExpenseRepository {     Expense Load(string id);     IEnumerable<Expense> GetExpenseTransactions(DateTime startDate,DateTime endDate);     void Save(Expense expense,string categoryId);     void Delete(string id);  } Let's create a concrete type for Expense Repository for handling CRUD operations. public class ExpenseRepository : IExpenseRepository {   private IDocumentSession session; public ExpenseRepository() {         session = MvcApplication.CurrentSession; } public Expense Load(string id) {     return session.Load<Expense>(id); } public IEnumerable<Expense> GetExpenseTransactions(DateTime startDate, DateTime endDate) {             //Querying using the Index name "ExpenseTransactions"     //filtering with dates     var expenses = session.LuceneQuery<Expense>("ExpenseTransactions")         .WaitForNonStaleResults()         .Where(exp => exp.Date >= startDate && exp.Date <= endDate)         .ToArray();     return expenses; } public void Save(Expense expense,string categoryId) {     var category = session.Load<Category>(categoryId);     if (string.IsNullOrEmpty(expense.Id))     {         //new expense transaction         expense.Category = category;         session.Store(expense);     }     else     {         //modifying an existing expense transaction         var expenseToEdit = Load(expense.Id);         //Copy values to  expenseToEdit         ModelCopier.CopyModel(expense, expenseToEdit);         //set category object         expenseToEdit.Category = category;       }     //save changes     session.SaveChanges(); } public void Delete(string id) {     var expense = Load(id);     session.Delete<Expense>(expense);     session.SaveChanges(); }   }  Insert/Update Expense Transaction The Save method is used for both insert a new expense record and modifying an existing expense transaction. For a new expense transaction, we store the expense object with associated category into document session object and load the existing expense object and assign values to it for editing a existing record.  public void Save(Expense expense,string categoryId) {     var category = session.Load<Category>(categoryId);     if (string.IsNullOrEmpty(expense.Id))     {         //new expense transaction         expense.Category = category;         session.Store(expense);     }     else     {         //modifying an existing expense transaction         var expenseToEdit = Load(expense.Id);         //Copy values to  expenseToEdit         ModelCopier.CopyModel(expense, expenseToEdit);         //set category object         expenseToEdit.Category = category;       }     //save changes     session.SaveChanges(); } Querying Expense transactions   public IEnumerable<Expense> GetExpenseTransactions(DateTime startDate, DateTime endDate) {             //Querying using the Index name "ExpenseTransactions"     //filtering with dates     var expenses = session.LuceneQuery<Expense>("ExpenseTransactions")         .WaitForNonStaleResults()         .Where(exp => exp.Date >= startDate && exp.Date <= endDate)         .ToArray();     return expenses; }  The GetExpenseTransactions method returns expense transactions using a LINQ query expression with a Date comparison filter. The Lucene Query is using a index named "ExpenseTransactions" for getting the result set. In RavenDB, Indexes are LINQ queries stored in the RavenDB server and would be  executed on the background and will perform query against the JSON documents. Indexes will be working with a lucene query expression or a set operation. Indexes are composed using a Map and Reduce function. Check out Ayende's blog post on Map/Reduce We can create index using RavenDB web admin tool as well as programmitically using its Client API. The below shows the screen shot of creating index using web admin tool. We can also create Indexes using Raven Cleint API as shown in the following code documentStore.DatabaseCommands.PutIndex("ExpenseTransactions",     new IndexDefinition<Expense,Expense>() {     Map = Expenses => from exp in Expenses                     select new { exp.Date } });  In the Map function, we used a Linq expression as shown in the following from exp in docs.Expensesselect new { exp.Date };We have not used a Reduce function for the above index. A Reduce function is useful while performing aggregate functions based on the results from the Map function. Indexes can be use with set operations of RavenDB.SET OperationsUnlike other document databases, RavenDB supports set based operations that lets you to perform updates, deletes and inserts to the bulk_docs endpoint of RavenDB. For doing this, you just pass a query to a Index as shown in the following commandDELETE http://localhost:8080/bulk_docs/ExpenseTransactions?query=Date:20100531The above command using the Index named "ExpenseTransactions" for querying the documents with Date filter and  will delete all the documents that match the query criteria. The above command is equivalent of the following queryDELETE FROM ExpensesWHERE Date='2010-05-31' Controller & ActionsWe have created Expense Repository class for performing CRUD operations for the Expense transactions. Let's create a controller class for handling expense transactions.   public class ExpenseController : Controller { private ICategoryRepository categoyRepository; private IExpenseRepository expenseRepository; public ExpenseController(ICategoryRepository categoyRepository, IExpenseRepository expenseRepository) {     this.categoyRepository = categoyRepository;     this.expenseRepository = expenseRepository; } //Get Expense transactions based on dates public ActionResult Index(DateTime? StartDate, DateTime? EndDate) {     //If date is not passed, take current month's first and last dte     DateTime dtNow;     dtNow = DateTime.Today;     if (!StartDate.HasValue)     {         StartDate = new DateTime(dtNow.Year, dtNow.Month, 1);         EndDate = StartDate.Value.AddMonths(1).AddDays(-1);     }     //take last date of startdate's month, if endate is not passed     if (StartDate.HasValue && !EndDate.HasValue)     {         EndDate = (new DateTime(StartDate.Value.Year, StartDate.Value.Month, 1)).AddMonths(1).AddDays(-1);     }       var expenses = expenseRepository.GetExpenseTransactions(StartDate.Value, EndDate.Value);     if (Request.IsAjaxRequest())     {           return PartialView("ExpenseList", expenses);     }     ViewData.Add("StartDate", StartDate.Value.ToShortDateString());     ViewData.Add("EndDate", EndDate.Value.ToShortDateString());             return View(expenses);            }   // GET: /Expense/Edit public ActionResult Edit(string id) {       var expenseModel = new ExpenseViewModel();     var expense = expenseRepository.Load(id);     ModelCopier.CopyModel(expense, expenseModel);     var categories = categoyRepository.GetCategories();     expenseModel.Category = categories.ToSelectListItems(expense.Category.Id.ToString());                    return View("Save", expenseModel);          }   // // GET: /Expense/Create   public ActionResult Create() {     var expenseModel = new ExpenseViewModel();               var categories = categoyRepository.GetCategories();     expenseModel.Category = categories.ToSelectListItems("-1");     expenseModel.Date = DateTime.Today;     return View("Save", expenseModel); }   // // POST: /Expense/Save // Insert/Update Expense Tansaction [HttpPost] public ActionResult Save(ExpenseViewModel expenseViewModel) {     try     {         if (!ModelState.IsValid)         {               var categories = categoyRepository.GetCategories();                 expenseViewModel.Category = categories.ToSelectListItems(expenseViewModel.CategoryId);                               return View("Save", expenseViewModel);         }           var expense=new Expense();         ModelCopier.CopyModel(expenseViewModel, expense);          expenseRepository.Save(expense, expenseViewModel.CategoryId);                       return RedirectToAction("Index");     }     catch     {         return View();     } } //Delete a Expense Transaction public ActionResult Delete(string id) {     expenseRepository.Delete(id);     return RedirectToAction("Index");     }     }     Download the Source - You can download the source code from http://ravenmvc.codeplex.com

• Stackify Aims to Put More ‘Dev’ in ‘DevOps’

  - by Matt Watson

  Originally published on VisualStudioMagazine.com on 8/22/2012 by Keith Ward.The Kansas City-based startup wants to make it easier for developers to examine the network stack and find problems in code.The first part of “DevOps” is “Dev”. But according to Matt Watson, Devs aren’t connected enough with Ops, and it’s time that changed.He founded the startup company Stackify earlier this year to do something about it. Stackify gives developers unprecedented access to the IT side of the equation, Watson says, without putting additional burden on the system and network administrators who ultimately ensure the health of the environment.“We need a product designed for developers, with the goal of getting them more involved in operations and app support. Now, there’s next to nothing designed for developers,” Watson says. Stackify allows developers to search the network stack to troubleshoot problems in their software that might otherwise take days of coordination between development and IT teams to solve.Stackify allows developers to search log files, configuration files, databases and other infrastructure to locate errors. A key to this is that the developers are normally granted read-only access, soothing admin fears that developers will upload bad code to their servers.Implementation starts with data collection on the servers. Among the information gleaned is application discovery, server monitoring, file access, and other data collection, according to Stackify’s Web site. Watson confirmed that Stackify works seamlessly with virtualized environments as well.Although the data collection software must be installed on Windows servers, it can monitor both Windows and Linux servers. Once collection’s finished, developers have the kind of information they need, without causing heartburn for the IT staff.Stackify is a 100 percent cloud-based service. The company uses Windows Azure for hosting, a decision Watson’s happy with. With Azure, he says, “It’s nice to have all the dev tools like cache and table storage.” Although there have been a few glitches here and there with the service, it’s run very smoothly for the most part, he adds.Stackify is currently in a closed beta, with a public release scheduled for October. Watson says that pricing is expected to be $25 per month, per server, with volume discounts available. He adds that the target audience is companies with at least five developers.Watson founded Stackify after selling his last company, VinSolutions, to AutoTrader.com for “close to $150 million”, according to press accounts. Watson has since  founded the Watson Technology Group, which focuses on angel investing.About the Author: Keith Ward is the editor in chief of Visual Studio Magazine.

• OWB 11gR2 &ndash; Flexible and extensible

  - by David Allan

  The Oracle data integration extensibility capabilities are something I love, nothing more frustrating than a tool or platform that is very constraining. I think extensibility and flexibility are invaluable capabilities in the data integration arena. I liked Uli Bethke's posting on some extensibility capabilities with ODI (see Nesting ODI Substitution Method Calls here), he has some useful guidance on making customizations to existing KMs, nice to learn by example. I thought I'd illustrate the same capabilities with ODI's partner OWB for the OWB community. There is a whole new world of potential. The LKM/IKM/CKM/JKMs are the primary templates that are supported (plus the Oracle Target code template), so there is a lot of potential for customizing and extending the product in this release. Enough waffle... Diving in at the deep end from Uli's post, in OWB the table operator has a number of additional properties in OWB 11gR2 that let you annotate the column usage with ODI-like properties such as the slowly changing usage or for your own user-defined purpose as in Uli's post, below you see for the target table SALES_TARGET we can use the UD5 property which when assigned the code template (knowledge module) which has been modified with Uli's change we can do custom things such as creating indices - provides The code template used by the mapping has the additional step which is basically the code illustrated from Uli's posting just used directly, the ODI 10g substitution references also supported from within OWB's runtime. Now to see whether this does what we expect before we execute it, we can check out the generated code similar to how the traditional mapping generation and preview works, you do this by clicking on the 'Inspect Code' button on the execution units code template assignment. This then  creates another tab with prefix 'Code - <mapping name>' where the generated code is put, scrolling down we find the last step with the indices being created, looks good, so we are ready to deploy and execute. After executing the mapping we can then use the 'Audit Information' panel (select the mapping in the designer tree and click on View/Audit Information), this gives us a view of the execution where we can drill into the tasks that were executed and inspect both the template and the generated code that was executed and any potential errors. Reflecting back on earlier versions of OWB, these were the kinds of features that were always highly desirable, getting under the hood of the code generation and tweaking bit and pieces - fun and powerful stuff! We can step it up a bit here and explore some further ideas. The example below is a daisy-chained set of execution units where the intermediate table is a target of one unit and the source for another. We want that table to be a global temporary table, so can tweak the templates. Back to the copy of SQL Control Append (for demo purposes) we modify the create target table step to make the table a global temporary table, with the option of on commit preserve rows. You can get a feel for some of the customizations and changes possible, providing some great flexibility and extensibility for the data integration tools.

• A Few Words from Oracle’s Channel Chief

  - by Meghan Fritz-Oracle

  As Oracle enters a new fiscal year, I want to take a moment and reflect on my time at Oracle thus far. The technology industry is currently at an inflection point trying to figure out where growth will come from. When you look at Oracle’s portfolio of products, it's a complete stack from applications to disc, offering differentiation in the marketplace. I was initially drawn to Oracle’s leadership, strategy, and world-class technology. Since joining the Oracle team in October 2013, I’ve had the privilege of traveling around the globe visiting our partners and customers, and wanted to share several common themes that came up during these meetings. Cloud: Many partners are trying to figure out how to build a business around the cloud. Oracle partners can currently resell or refer our cloud services. We saw over 300 percent growth from cloud resale last quarter. Engineered Systems: Hardware and software integrated together to simplify IT allows our joint customers to focus on the innovation they need to compete in a complex marketplace. We're seeing great success in a several areas, with more partners saying, “Let’s start with Oracle on Oracle.” The Internet of Things: This is the next big opportunity for device manufacturers and ISV‘s to capture market share in what is projected to be a mulit-trillion-dollar opportunity, according to Gartner.  Competition: We've got a tremendous middleware platform and a tremendous database install base. We’re not just a database company; we are a complete provider. So looking ahead, what are my priorities for fiscal 2015? Oracle PartnerNetwork has some very exciting plans on the horizon. There’s a lot more leadership and announcements to unfold, especially at this year’s Global Partner Kickoff taking place on June 25 + 26 depending on your region and time zone. I along with several other Oracle executives will be shedding light on Oracle’s strategy for the upcoming year, the latest opportunities within the OPN Specialized Program and sales strategies that will help you to continue to grow and profit with Oracle. Stay tuned for registration information next week.We also have Oracle OpenWorld and JavaOne to look forward to. These conferences are taking place in San Francisco from September 28 – October 2. We’ll have a variety of partner-specific activities for you at OPN Central @ OpenWorld including the OPN keynote, the famed AfterDark networking reception, access to the OPN Lounge and more.In the meantime, I hope that everyone has a great end to fiscal 2014.Best regards,Rich Geraffo Senior Vice President, Worldwide Alliances and Channels

• Best development architecture for a small team of programmers

  - by Tio

  Hi all.. I'm in the first month of work in a new company.. and after I met the two programmer's and asked how things are organized in terms of projects inside the company, they simply shrug their shoulders, and said that nothing is organized.. I think my jaw hit the ground that same time.. ( I know some, of you think I should quit, but I'm on a privileged position, I'm the most experienced there, so there's room for me to grow inside the company, and I'm taking the high road ).. So I talked to the IT guy, and one of the programmers, and maybe this week I'm going to get a server all to myself to start organizing things. I've used various architectures in my previous work experiences, on one I was developing in a server on the network ( no source control of course ).. another experience I had was developing in my local computer, with no server on the network, just source control. And at home, I have a mix of the two, everything I code is on a server on the network, and I have those folders under source control, and I also have a no-ip account configured on that server so I can access it everywhere and I can show the clients anything. For me I think this last solution ( the one I have at home ) is the best: Network server with LAMP stack. The server as a public IP so we can access it by domain name. And use subdomains for each project. Everybody works directly on the network server. I think the problem arises, when two or more people want to work on the same project, in this case the only way to do this is by using source control and local repositories, this is great, but I think this turns development a lot more complicated. In the example I gave, to make a change to the code, I would simply need to open the file in my favorite editor, make the change, alter the database, check in the changes into source control and presto all done. Using local repositories, I would have to get the latest version, run the scripts on the local database to update it, alter the file, alter the database, check in the changes to the network server, update the database on the network server, see if everything is running well on the network server, and presto all done, to me this seems overcomplicated for a change on a simple php page. I could share the database for the local development and for the network server, that sure would help. Maybe the best way to do this is just simply: Network server with LAMP stack ( test server so to speak ), public server accessible trough the web. LAMP stack on every developer computer ( minus the database ) We develop locally, test, then check in the changes into the server test and presto. What do you think? Maybe I should start doing this at home.. Thanks and best regards...

• Cost justification for buying a 32GB superfast Alienware M18x with a price tag of around £5K ($10K)

  - by tonyrogerson

  When considering buying a laptop that’s going to cost me around £5,000 I really need to justify the purchase from a business perspective; my Lenovo W700 has served me very well for the last 2 years, it’s an extremely good machine and as solid as a rock (and as heavy), alas though it is limited to the 8GB. As SQL Server 2012 approaches and with my interest in working in the Business Intelligence space over the next year or two it is clear I need a powerful machine that I can run a full infrastructure though virtualised. My requirements For High Availability / Disaster Recovery research and demonstration Machine for a domain controller Four machines in a shared disk cluster (SQL Server Clustering active – active etc.) Five  machines in a file share cluster (SQL Server Availability Groups) For Business Intelligence research and demonstration Not entirely sure how many machine I want to run here, but it would be to cover the entire BI stack in an enterprise setting, sharepoint, sql server etc. For Big Data Research I have a fondness for the NoSQL approach to scalability and dealing with large volumes so I need a number of machines to research VoltDB, Hadoop etc. As you can see the requirements for a SQL Server consultant to service their clients well is considerable; will 8GB suffice, alas no, it will no longer do. I’m a very strong believer that in order to do your job well you must expense it, short cuts only cost you time, waiting 5 minutes instead of an hour for something to run not only saves me time but my clients time, I can do things quicker and more importantly I can demonstrate concepts. My W700 with the 8GB of RAM and SSD’s cost me around £3.5K two years ago, to be honest I’ve not got the full use I wanted out of it but the machine has had the power when I’ve needed it, it’s served me and my clients well. Alienware now do a model (the M18x) with 32GB of RAM; yes 32GB in a laptop! Dual drives so I can whack a couple of really good SSD’s in there, a quad core with hyper threading i7 and a decent speed. I can reduce the cost of the memory by getting it from Crucial, so instead of £1.5K for 32GB it will be around £900, I can also cost save on the SSD as well. The beauty about the M18x is that it is USB3.0, SATA 3 and also really importantly has eSATA, running VM’s will never be easier, I can have a removeable SSD with my VM’s on it and can plug it into my home machine or laptop – an ideal world! The initial outlay of £5K is peanuts compared to the benefits I’ll give my clients, I will be able to present real enterprise concepts, I’ll also be able to give training on those real enterprise concepts and with real, albeit virtualised machines.

• How to Disable Access to the Registry in Windows 7

  - by Mysticgeek

  If you don’t know what your doing in the Registry, you can mess up your computer pretty good. Today we show you how to prevent users from accessing the Registry and making any changes to it. Using Local Group Policy Editor Note: This method uses Group Policy Editor which is not available in Home versions of Windows. First type gpedit.msc into the Search box in the Start menu. When Group Policy Editor opens, navigate to User Configuration \ Administrative Templates then select System. Under Setting in the right panel double-click on Prevent access to registry editing tools. Select the radio button next to Enabled, click OK, then close out of Group Policy Editor. Now if a user tries to access the Registry… They will get the following message advising they cannot access it.   Using Registry Enabler & Disabler 3 If you’re using Home or Starter version of Windows 7, you can use a neat utility called Registry Enabler & Disabler (link below). This app works on XP and Vista as well. There is no installation involved so you can run it from a flash drive, disable the registry, then take the flash drive with you while a the user is on the machine.   Again, if the user tries to access the Registry they will get the following error… Using one of these options will stop users from gaining access to the Registry or running any registry hacks. Of course if you have a shared computer, you may want to set up other users with a Standard Account, as they won’t be able to make changes to the Registry anyway.

• 64-bit 13.10 shows 1GB less RAM than 64-bit 13.04 did

  - by kiloseven

  Multiple 64-bit versions (Kubuntu, Lubuntu and Xubuntu) once installed on my ThinkPad R60 show 3GB of RAM, not the correct 4GB of RAM.

• A few things I learned regarding Azure billing policies

  - by Vincent Grondin

  An hour of small computing time: 0,12$ per hour A Gig of storage in the cloud: 0,15$ per hour 1 Gig of relational database using Azure SQL: 9,99$  per month A Visual Studio Professional with MSDN Premium account: 2500$ per year Winning an MSDN Professional account that comes preloaded with 750 free hours of Azure per month:  PRICELESS !!!      But was it really free???? Hmmm… Let’s see.....   Here's a few things I learned regarding Azure billing policies when I attended a promotional training at Microsoft last week...   1)  An instance deployed in the cloud really means whatever you upload in there... it doesn't matter if it's in STAGING OR PRODUCTION!!!!   Your MSDN account comes with 750 free hours of small computing time per month which should be enough hours per month for one instance of one application deployed in the cloud...  So we're cool, the application you run in the cloud doesn't cost you a penny....  BUT the one that's in staging is still consuming time!!!   So if you don’t want to end up having to pay 42$ at the end of the month on your credit card like this happened to a friend of mine, DELETE them staging applications once you’ve put them in production! This also applies to the instance count you can modify in the configuration file… So stop and think before you decide you want to spawn 50 of those hello world apps  .     2) If you have an MSDN account, then you have the promotional 750 hours of Azure credits per month and can use the Azure credits to explore the Cloud! But be aware, this promotion ends in 8 months (maybe more like 7 now) and then you will most likely go back to the standard 250 hours of Azure credits. If you do not delete your applications by then, you’ll get billed for the extra hours, believe me…   There is a switch that you can toggle and which will STOP your automatic enrollment after the promotion and prevent you from renewing the Azure Account automatically. Yes the default setting is to automatically renew your account and remember, you entered your credit card information in the registration process so, yes, you WILL be billed…  Go disable that ASAP    Log into your account, go to “Windows Azure Platform” then click the “Subscriptions” tab and on the right side, you’ll see a drop down with different “Actions” into it… Choose “Opt out of auto renew” and, NOW you’re safe…   Still, this is a great offer by Microsoft and I think everyone that has a chance should play a bit with Azure to get to know this technology a bit more...     Happy Cloud Computing All

• Nginx and PHP Fundamentals

  - by Elton Stoneman

  Originally posted on: http://geekswithblogs.net/EltonStoneman/archive/2013/08/01/nginx-and-php-fundamentals.aspxHot on the heels of my .NET caching course, I’ve had my first “fundamentals” course released on Pluralsight: Nginx and PHP Fundamentals. It’s a practical look at two of the biggest technologies on the web – Nginx, which is the fastest growing HTTP server around (currently hosting 100+ million sites), and PHP, which powers more websites than any other server-side framework (currently 240+ million sites). The two technologies work well together, both are open-source and cross-platform and both are lightweight and easy to get started with - you just need to download and unzip the runtimes, and with a text editor you can create and host dynamic websites. I’ve used PHP as a second (sometimes third) language since 2005 when I was brought cold into an established codebase to help improve performance, and Nginx to host tier 2 apps for the last couple of years. As with any training course, you learn new things as you produce it, and it was good to focus on a different stack from my commercial .NET world. In the course I start with a website in two parts – one which is just static content, and one which processes a user registration form using ASP.NET MVC, both running in IIS. Over four modules I migrate the app to Nginx and PHP: Hosting Static Content in Nginx – how to deploy and configure Nginx for a basic website; PHP Part 1: Basic Web Forms – installing PHP and an IDE, and building a simple form with server-side validation; PHP Part 2: Packages and Integration – using PECL and Composer for packages to connect to Azure, AWS, Mongo and reCAPTCHA; Hosting PHP in Nginx – configuring Nginx to host our PHP site. Along the way I run some performance stats with JMeter, and the headlines are that Nginx running on Linux outperforms IIS on Windows for static content,by 800 requests per second over 1000 concurrent requests; and Linux+Ngnix+PHP outperforms Windows+IIS+ASP.NET MVC by 700 request per second with the same load. Of course, the headline stats don’t tell the whole story, and when you add OpCode caching for PHP and the ASP.NET Output Cache, the results are very different. As Web architecture moves away from heavy server-side processing, to Single Page Apps with client-side frameworks like AngularJS and Knockout, I think there’s an increasing need for high-performance, low-cost server technologies, and the combination of Nginx and PHP makes a compelling case.

• Oracle collaborates with leading IT vendors on Cloud Management Standards

  - by Anand Akela

  During the last couple of days, two key specifications for cloud management standards have been announced. Oracle collaborated with leading technology vendors from the IT industry on both of these cloud management specifications. One of the specifications focuses "Infrastructure as a Service" ( IaaS )  cloud service model , while the other specification announced today focuses on "Platform as a Service" ( PaaS ) cloud service model. Please see The NIST Definition of Cloud Computing to learn more about IaaS and PaaS . Earlier today Oracle , CloudBees, Cloudsoft, Huawei, Rackspace, Red Hat, and Software AG   announced the Cloud Application Management for Platforms (CAMP) specification that will be submitted to Organization for the Advancement of Structured Information Standards (OASIS) for development of an industry standard, in an effort to help ensure interoperability for deploying and managing applications across cloud environments.  Typical PaaS architecture - Source : CAMP specification The CAMP specification defines the artifacts and APIs that need to be offered by a PaaS cloud to manage the building, running, administration, monitoring and patching of applications in the cloud. Its purpose is to enable interoperability among self-service interfaces to PaaS clouds by defining artifacts and formats that can be used with any conforming cloud and enable independent vendors to create tools and services that interact with any conforming cloud using the defined interfaces. Cloud vendors can use these interfaces to develop new PaaS offerings that will interact with independently developed tools and components. In a separate cloud standards announcement yesterday, the Distributed Management Task Force ( DMTF ), the organization bringing the IT industry together to collaborate on systems management standards development, validation, promotion and adoption, released the new Cloud Infrastructure Management Interface (CIMI) specification. Oracle collaborated with various technology vendors and industry organizations on this specification. CIMI standardizes interactions between cloud environments to achieve interoperable cloud infrastructure management between service providers and their consumers and developers, enabling users to manage their cloud infrastructure use easily and without complexity. DMTF developed CIMI as a self-service interface for infrastructure clouds ( IaaS focus ) , allowing users to dynamically provision, configure and administer their cloud usage with a high-level interface that greatly simplifies cloud systems management. Mark Carlson, Principal Cloud Strategist at Oracle provides more details about CAMP  and CIMI his blog . Stay Connected: Twitter |  Face book |  You Tube |  Linked in |  Newsletter

• Silverlight User Group of Switzerland (SLUGS)

  - by Laurent Bugnion

  Last Thursday, the Silverlight Firestarter event took place in Redmond, and was streamed live to a large audience worldwide (around 20’000 people). Approximately 30 if them were in Wallisellen near Zurich, in Microsoft Switzerland’s offices. This was not only a great occasion to learn more about the future of Silverlight and to see great demos, but also it was the very first meeting of the Silverlight User Group of Switzerland (SLUGS). Having 30 people for a first meeting was a great success, especially if we consider that it was REALLY cold that night, that it had snowed 20 cm the night before! We all had a good time, and 3 lucky winners went back home with a prize: One LG Optimus 7 Windows Phone and two copies of Silverlight 4 Unleashed. Congratulations to the winners! After the keynote (which went in a whirlwind, shortest 90 minutes ever!), we all had pizza and beverages generously sponsored by the Swiss DPE team, of which not less than 5 guys came to the event! Thanks to Stefano, Ronnie, Sascha, Big Mike and Ken for attending! We decided to have meetings every month. Stay tuned for announcements on when and where the events will take place. We are also in the process of creating various groups online where the attendees can find more information. For instance, I created a group on Flickr where the pictures taken at events will be published. The group is public, and the pictures of the first event are already online! We also have the already known page at http://www.slugs.ch/, check it out. A national group Even though the first event was in Zurich, and that 3 of the founding members live nearby, we would like to try and be a national group. That means having events sometimes in other parts of Switzerland, collaborating with other local user groups, etc. Stay tuned for more Join! We want you, we need you If you are doing Silverlight, for a living or as a hobby, if you are interested in user experience, XAML, Expression Blend and many more topics, you should consider joining! This is a great occasion to exchange experiences, to learn from Silverlight experts, to hear sessions about various topics related to Silverlight, etc. If you want to talk about a topic that is of interest to you, If you want to propose a topic of discussion Or if you just want to hang out then go to http://www.slugs.ch and register!

• How to perform feature upgrade in SharePoint2010 part2

  - by ybbest

  In my last post, I showed you how to perform feature upgrade and upgrade my feature from 0.0.0.0 to 1.0.0.1. In this post, I’d like to continue on this topic and upgrade the feature again. For the first version of my solution, I deploy a document library with a custom document set content type and then upgrade the solution so I index the application number column. Now , I will create a new version of the solution so that it will remove the threshold of the list. You can download the solution here. Once you extract your solution, the first version is in the original folder. In order to deploy the original solution, you need to run the sitecreation.ps1 in the script folder. The version 1.1 will be in the Upgrade folder and version 1.2 will be in the Upgrade2 folder. You need to make the following changes to the existing solution. 1. Modify the ApplicationLibrary.Template.xml as highlighted below: 2. Adding the following code into the feature event receiver. </pre> public override void FeatureUpgrading(SPFeatureReceiverProperties properties, string upgradeActionName, System.Collections.Generic.IDictionary<string, string> parameters) { base.FeatureUpgrading(properties, upgradeActionName, parameters); SPWeb web = GetFeatureWeb(properties); SPList applicationLibrary = web.Lists.TryGetList(ApplicationLibraryNamesConstant.ApplicationLibraryName); switch (upgradeActionName) { case "IndexApplicationNumber": if (applicationLibrary != null) { SPField queueField = applicationLibrary.Fields["ApplicationNumber"]; queueField.Indexed = true; queueField.Update(); } break; case "RemoveListThreshold": applicationLibrary.EnableThrottling = false; applicationLibrary.Update(); break; } } <pre> 3. Package your solution and run the feature upgrade PowerShell script. $wspFolder ="v1.2" $scriptPath=Split-Path $myInvocation.MyCommand.Path $siteUrl = "http://ybbest" $featureToCheckGuid="1b9d84cd-227d-45f1-92d4-a43008aa8fe7" $requiredFeatureVersion="1.0.0.1" $siteUrlOfFeatureToBeChecked="http://ybbest" AppendLog "Starting Solution UpgradeSolutionAndFeatures.ps1" Magenta & "$scriptPath\UpgradeSolutionAndFeatures.ps1" $siteUrl $wspFolder $featureToCheckGuid $requiredFeatureVersion $siteUrlOfFeatureToBeChecked Write-Host AppendLog "All features updated" "Green" References: Feature upgrade.

• SQL SERVER – ColumnStore Index – Batch Mode vs Row Mode

  - by pinaldave

  What do you do when you are in a hurry and hear someone say things which you do not agree or is wrong? Well, let me tell you what I do or what I recently did. I was walking by and heard someone mentioning “Columnstore Index are really great as they are using Batch Mode which makes them seriously fast.” While I was passing by and I heard this statement my first reaction was I thought Columnstore Index can use both – Batch Mode and Row Mode. I stopped by even though I was in a hurry and asked the person if he meant that Columnstore indexes are seriously fast because they use Batch Mode all the time or Batch Mode is one of the reasons for Columnstore Index to be faster. He responded that Columnstore Indexes can run only in Batch Mode. However, I do not like to confront anybody without hearing their complete story. Honestly, I like to do information sharing and avoid confronting as much as possible. There are always ways to communicate the same positively. Well, this is what I did, I quickly pull up my earlier article on Columnstore Index and copied the script to SQL Server Management Studio. I created two versions of the script. 1) Very Large Table 2) Reasonably Small Table. I a query which uses columnstore index on both of the versions. I found very interesting result of the my tests. I saved my tests and sent it to the person who mentioned about that Columnstore Indexes are using Batch Mode only. He immediately acknowledged that indeed he was incorrect in saying that Columnstore Index uses only Batch Mode. What really caught my attention is that he also thanked me for sending him detail email instead of just having argument where he and I both were standing in the corridor and neither have no way to prove any theory. Here is the screenshots of the both the scenarios. 1) Columnstore Index using Batch Mode 2) Columnstore Index using Row Mode Here is the logic behind when Columnstore Index uses Batch Mode and when it uses Row Mode. A batch typically represents about 1000 rows of data. Batch mode processing also uses algorithms that are optimized for the multicore CPUs and increased memory throughput.  Batch mode processing spreads metadata access costs and overhead over all the rows in a batch.  Batch mode processing operates on compressed data when possible leading superior performance. Here is one last point – Columnstore Index can use Batch Mode or Row Mode but Batch Mode processing is only available in Columnstore Index. I hope this statement truly sums up the whole concept.
