• CSV Anyone?

  - by Tim Dexter

  CSV, a dead format? With today's abilities to generate Excel output (Im working on some posts for the shiny new Excel templates) and the sophistication of the eText outputs, do you really need CSV? I guess so seeing as it was added after the base product was released as an enhancement. But I'd be interested in hearing use cases? I used to think the same of text output. But now Im working in the public sector where older technologies abound I can see a use for text output. Its also used as a machine readable format, etc. BIP still does not support a text format from its RTF templates but its very doable using XSL templates. Back to CSV, I noticed an enhancement in the big list of new stuff in the 10.1.3.4.1 rollup. You can now generate CSV from structured data ie a data template or a SQL XML query. This piqued my interest so I ran off a data template to CSV. Its interesting, in a geeky kinda way, I guess Im that way inclined.Here's my data structure:<EMPLOYEES> <LIST_G_DEPT> <G_DEPT>  <DEPARTMENT_ID>10</DEPARTMENT_ID>  <DEPARTMENT_NAME>Administration</DEPARTMENT_NAME>  <LIST_G_EMP>   <G_EMP>     <EMPLOYEE_ID>200</EMPLOYEE_ID>     <EMP_NAME>Jennifer Whalen</EMP_NAME>     <EMAIL>JWHALEN</EMAIL>     <PHONE_NUMBER>515.123.4444</PHONE_NUMBER>     <HIRE_DATE>1987-09-17T00:00:00.000-06:00</HIRE_DATE>     <SALARY>4400</SALARY>    </G_EMP>   </LIST_G_EMP>  <TOTAL_EMPS>1</TOTAL_EMPS>  <TOTAL_SALARY>4400</TOTAL_SALARY>  <AVG_SALARY>4400</AVG_SALARY>  <MAX_SALARY>4400</MAX_SALARY>  <MIN_SALARY>4400</MIN_SALARY> </G_DEPT>Poor ol Jennifer, she needs some help in the Admin department :0)Pushing this to CSV and BP completely flattens the data out so you get a completely denormalized data output in the CSV.TOTAL_SALARY,DEPARTMENT_ID,DEPARTMENT_NAME,MIN_SALARY,AVG_SALARY,MAX_SALARY,EMPLOYEE_ID,SALARY,PHONE_NUMBER,HIRE_DATE,EMP_NAME,EMAIL,TOTAL_EMPS4400,10,Administration,4400,4400,4400,200,4400,515.123.4444,1987-09-17T00:00:00.000-06:00,"Jennifer Whalen",JWHALEN,119000,20,Marketing,6000,9500,13000,201,13000,515.123.5555,1996-02-17T00:00:00.000-07:00,"Michael Hartstein",MHARTSTE,219000,20,Marketing,6000,9500,13000,202,6000,603.123.6666,1997-08-17T00:00:00.000-06:00,"Pat Fay",PFAY,2Useful? Its a little confusing to start with but it is completely de-normalized so there is lots of repetition. But if it floats your boat, you got it!

• Unit Testing DateTime – The Crazy Way

  - by João Angelo

  We all know that the process of unit testing code that depends on DateTime, particularly the current time provided through the static properties (Now, UtcNow and Today), it’s a PITA. If you go ask how to unit test DateTime.Now on stackoverflow I’ll bet that you’ll get two kind of answers: Encapsulate the current time in your own interface and use a standard mocking framework; Pull out the big guns like Typemock Isolator, JustMock or Microsoft Moles/Fakes and mock the static property directly. Now each alternative has is pros and cons and I would have to say that I glean more to the second approach because the first adds a layer of abstraction just for the sake of testability. However, the second approach depends on commercial tools that not every shop wants to buy or in the not so friendly Microsoft Moles. (Sidenote: Moles is now named Fakes and it will ship with VS 2012) This tends to leave people without an acceptable and simple solution so after reading another of these types of questions in SO I came up with yet another alternative, one based on the first alternative that I presented here but tries really hard to not get in your way with yet another layer of abstraction. So, without further dues, I present you, the Tardis. The Tardis is single section of conditionally compiled code that overrides the meaning of the DateTime expression inside a single class. You still get the normal coding experience of using DateTime all over the place, but in a DEBUG compilation your tests will be able to mock every static method or property of the DateTime class. An example follows, while the full Tardis code can be downloaded from GitHub: using System; using NSubstitute; using NUnit.Framework; using Tardis; public class Example { public Example() : this(string.Empty) { } public Example(string title) { #if DEBUG this.DateTime = DateTimeProvider.Default; this.Initialize(title); } internal IDateTimeProvider DateTime { get; set; } internal Example(string title, IDateTimeProvider provider) { this.DateTime = provider; #endif this.Initialize(title); } private void Initialize(string title) { this.Title = title; this.CreatedAt = DateTime.UtcNow; } private string title; public string Title { get { return this.title; } set { this.title = value; this.UpdatedAt = DateTime.UtcNow; } } public DateTime CreatedAt { get; private set; } public DateTime UpdatedAt { get; private set; } } public class TExample { public void T001() { // Arrange var tardis = Substitute.For<IDateTimeProvider>(); tardis.UtcNow.Returns(new DateTime(2000, 1, 1, 6, 6, 6)); // Act var sut = new Example("Title", tardis); // Assert Assert.That(sut.CreatedAt, Is.EqualTo(tardis.UtcNow)); } public void T002() { // Arrange var tardis = Substitute.For<IDateTimeProvider>(); var sut = new Example("Title", tardis); tardis.UtcNow.Returns(new DateTime(2000, 1, 1, 6, 6, 6)); // Act sut.Title = "Updated"; // Assert Assert.That(sut.UpdatedAt, Is.EqualTo(tardis.UtcNow)); } } This approach is also suitable for other similar classes with commonly used static methods or properties like the ConfigurationManager class.

  Liebe Oracle Partner, und schon wieder ist ein Geschäftsjahr zu Ende gegangen. Als erstes möchte ich Ihnen, unseren Partnern, sagen: Sie leisten seit Jahren einen fundamentalen Beitrag zum Erfolg von Oracle – auch im Fiskaljahr 2012. Herzlichen Dank dafür! Wenn wir auf das letzte Jahr zurückblicken, gab es unter dem Motto „Oracle on Oracle“ herausragende Produktvorstellungen, Events und Partner Programme. Zu den wichtigsten technischen Innovationen gehörte sicherlich die Oracle Database Appliance speziell für kleinere Unternehmen. Auch die Daten-Explosion, zu der wir jeden Tag beitragen, stellt für alle Unternehmen eine Herausforderung dar. Um diese „Big Data“ effizient zu verwalten, haben wir die Exa-Familie erweitert. So stehen neben der Exadata Database Machine nun auch Exalogic und Exalytics – mit zuverlässiger Hardware, ausgereifter Software und Support aus einer Hand – je nach Bedarf zur Verfügung. Da ist für jeden Kunden was dabei. Die Oracle Optimized Solutions unserer VADs waren ein weiteres wichtiges Thema, speziell für den Mittelstand, über das wir auch hier im Blog berichtet haben. Für ISVs wurden die Exastack Ready und Exastack Optimized Programme entwickelt. Speziell für Partner wurden Partner Sales Books zu den Fokus-Themen, wie beispielsweise Cloud Computing, erstellt. Im OPN stehen Ihnen mehr als 30 deutschsprachige Marketing-Kits zur Verfügung, um Sie bei der täglichen Vertriebsarbeit zu unterstützen. Und mit dem überarbeiteten und erweiterten Solutions Catalog im OPN können Sie von Endkunden ganz einfach nach Ihrem Lösungsangebot gefunden werden.

• PASS Summit 2011 &ndash; Part IV

  - by Tara Kizer

  This is the final blog for my PASS Summit 2011 series.  Well okay, a mini-series, I guess. On the last day of the conference, I attended Keith Elmore’ and Boris Baryshnikov’s (both from Microsoft) “Introducing the Microsoft SQL Server Code Named “Denali” Performance Dashboard Reports, Jeremiah Peschka’s (blog|twitter) “Rewrite your T-SQL for Great Good!”, and Kimberly Tripp’s (blog|twitter) “Isolated Disasters in VLDBs”. Keith and Boris talked about the lifecycle of a session, figuring out the running time and the waiting time.  They pointed out the transient nature of the reports.  You could be drilling into it to uncover a problem, but the session may have ended by the time you’ve drilled all of the way down.  Also, the reports are for troubleshooting live problems and not historical ones.  You can use Management Data Warehouse for historical troubleshooting.  The reports provide similar benefits to the Activity Monitor, however Activity Monitor doesn’t provide context sensitive drill through. One thing I learned in Keith’s and Boris’ session was that the buffer cache hit ratio should really never be below 87% due to the read-ahead mechanism in SQL Server.  When a page is read, it will read the entire extent.  So for every page read, you get 7 more read.  If you need any of those 7 extra pages, well they are already in cache.  I had a lot of fun in Jeremiah’s session about refactoring code plus I learned a lot.  His slides were visually presented in a fun way, which just made for a more upbeat presentation.  Jeremiah says that before you start refactoring, you should look at your system.  Investigate missing or too many indexes, out-of-date statistics, and other areas that could be leading to your code running slow.  He talked about code standards.  He suggested using common abbreviations for aliases instead of one-letter aliases.  I’m a big offender of one-letter aliases, but he makes a good point.  He said that join order does not matter to the optimizer, but it does matter to those who have to read your code.  Now let’s get into refactoring! Eliminate useless things – useless/unneeded joins and columns.  If you don’t need it, get rid of it! Instead of using DISTINCT/JOIN, replace with EXISTS Simplify your conditions; use UNION or better yet UNION ALL instead of OR to avoid a scan and use indexes for each union query Branching logic – instead of IF this, IF that, and on and on…use dynamic SQL (sp_executesql, please!) or use a parameterized query in the application Correlated subqueries – YUCK! Replace with a join Eliminate repeated patterns Last, but certainly not least, was Kimberly’s session.  Kimberly is my favorite speaker.  I attended her two-day pre-conference seminar at PASS Summit 2005 as well as a SQL Immersion Event last December.  Did I mention she’s my favorite speaker?  Okay, enough of that. Kimberly’s session was packed with demos.  I had seen some of it in the SQL Immersion Event, but it was very nice to get a refresher on these, especially since I’ve got a VLDB with some growing pains.  One key takeaway from her session is the idea to use a log shipping solution with a load delay, such as 6, 8, or 24 hours behind the primary.  In the case of say an accidentally dropped table in a VLDB, we could retrieve it from the secondary database rather than waiting an eternity for a restore to complete.  Kimberly let us know that in SQL Server 2012 (it finally has a name!), online rebuilds are supported even if there are LOB columns in your table.  This will simplify custom code that intelligently figures out if an online rebuild is possible. There was actually one last time slot for sessions that day, but I had an airplane to catch and my kids to see!

• Cox Communications' Strategic Approach to Enterprise User Experience: How Change Management and Usab

  - by Applications User Experience

  Author: Anna Wichansky, Senior Director, Applications User Experience, and Chair, Oracle Usability Advisory Board As part of our work in the User Experience group, our teams often go to Customer events such as the Higher Education User Group (HEUG) conference, Alliance 2010. This year's event was held in San Antonio, Texas, and was attended by hundreds of higher education, government, and public sector users of Oracle applications. The User Assistance team used this opportunity to reach out to customers in the Educational and Government sectors to better understand how their organizations are currently approaching help, messages, and other forms of user assistance. What is User Assistance? For us, user assistance is more than the old books of users' manuals and documentation. User assistance is anything that helps users get their jobs done quickly and efficiently. Instead of expecting users to stop and look through a guide or manual, we have been developing solutions that are embedded within the interface. We know that when people are having difficulty with a task, they want to be able to search efficiently for solutions and collaborate with coworkers. We know that they want to find their answers right there, right then, so that they can get on with their work. In our interviews at Alliance, we wanted to learn what the participants could tell us about what was happening on their campuses and in their institutions. Figure 1. For Oracle User Assistance, it's not just about books any more. So what did we do? Off to Texas, we recruited 10 people from nine different government and education organizations to come to our Oracle User Experience Onsite Usability Labs. We conducted one-hour interviews with these folks and asked them all about User Assistance--what people are doing, what they would like to do, what technologies they are using, what they would like to use, and ultimately what should we as a company be planning for our future products. We used this as an opportunity also to show them some of our design concepts for Fusion User Assistance, our next generation of user assistance based on the best of our user assistance in other products. Figure 2. Interviewing a technical user at Alliance. What we learned... People are not using paper or online manuals anymore. They don't want to see a manual that is written for technical users and that doesn't make sense to the ordinary end user. They really don't want to have to flip through a manual trying to find an answer to their question. Even when the answer might be tailored to their organization, they don't want to dig through documentation. When they need an answer now, they don't have the patience to dig for something that might or might not be clearly written. What does it mean to an organization when users don't want to deal with documentation? In many cases, it means that frustrated users make phone calls to try to find the answers that they need immediately. Phone calls are expensive to an organization and frustrating to the technical support staff who have provided documentation that no one wants to read anymore. If they don't call, they email for help often, and many users are asking for the same information. The bottom line is that if they could get that help immediately in the interface, they wouldn't have to make those calls or send those emails -- and that saves time and money. Our Fusion User Assistance options to customize help and get help for the task immediately were seen as an opportunity by these technical users to build the solutions that their users need and want. Figure 3. Joyce Ohgi and Laurie Pattison of Applications UX. Chicken Fried Steak. That was huge. But then, this was Texas, where we discovered a lot of things come very big. Drinks are served in quart-size glasses and dishes like Chicken Fried Steaks are served on platters not plates. We saw three-pound cinnamon rolls that you down with tea sweet enough to curl your hair. Deep in the heart of Texas, we learned a lot, and we ate even more.

• SQL SERVER – Updating Data in A Columnstore Index

  - by pinaldave

  So far I have written two articles on Columnstore Indexes, and both of them got very interesting readership. In fact, just recently I got a query on my previous article on Columnstore Index. Read the following two articles to get familiar with the Columnstore Index. They will give you a reference to the question which was asked by a certain reader: SQL SERVER – Fundamentals of Columnstore Index SQL SERVER – How to Ignore Columnstore Index Usage in Query Here is the reader’s question: ” When I tried to update my table after creating the Columnstore index, it gives me an error. What should I do?” When the Columnstore index is created on the table, the table becomes Read-Only table and it does not let any insert/update/delete on the table. The basic understanding is that Columnstore Index will be created on the table that is very huge and holds lots of data. If a table is small enough, there is no need to create a Columnstore index. The regular index should just help it. The reason why Columnstore index was needed is because the table was so big that retrieving the data was taking a really, really long time. Now, updating such a huge table is always a challenge by itself. If the Columnstore Index is created on the table, and the table needs to be updated, you need to know that there are various ways to update it. The easiest way is to disable the Index and enable it. Consider the following code: USE AdventureWorks GO -- Create New Table CREATE TABLE [dbo].[MySalesOrderDetail]( [SalesOrderID] [int] NOT NULL, [SalesOrderDetailID] [int] NOT NULL, [CarrierTrackingNumber] [nvarchar](25) NULL, [OrderQty] [smallint] NOT NULL, [ProductID] [int] NOT NULL, [SpecialOfferID] [int] NOT NULL, [UnitPrice] [money] NOT NULL, [UnitPriceDiscount] [money] NOT NULL, [LineTotal] [numeric](38, 6) NOT NULL, [rowguid] [uniqueidentifier] NOT NULL, [ModifiedDate] [datetime] NOT NULL ) ON [PRIMARY] GO -- Create clustered index CREATE CLUSTERED INDEX [CL_MySalesOrderDetail] ON [dbo].[MySalesOrderDetail] ( [SalesOrderDetailID]) GO -- Create Sample Data Table -- WARNING: This Query may run upto 2-10 minutes based on your systems resources INSERT INTO [dbo].[MySalesOrderDetail] SELECT S1.* FROM Sales.SalesOrderDetail S1 GO 100 -- Create ColumnStore Index CREATE NONCLUSTERED COLUMNSTORE INDEX [IX_MySalesOrderDetail_ColumnStore] ON [MySalesOrderDetail] (UnitPrice, OrderQty, ProductID) GO -- Attempt to Update the table UPDATE [dbo].[MySalesOrderDetail] SET OrderQty = OrderQty +1 WHERE [SalesOrderID] = 43659 GO /* It will throw following error Msg 35330, Level 15, State 1, Line 2 UPDATE statement failed because data cannot be updated in a table with a columnstore index. Consider disabling the columnstore index before issuing the UPDATE statement, then rebuilding the columnstore index after UPDATE is complete. */ A similar error also shows up for Insert/Delete function. Here is the workaround. Disable the Columnstore Index and performance update, enable the Columnstore Index: -- Disable the Columnstore Index ALTER INDEX [IX_MySalesOrderDetail_ColumnStore] ON [dbo].[MySalesOrderDetail] DISABLE GO -- Attempt to Update the table UPDATE [dbo].[MySalesOrderDetail] SET OrderQty = OrderQty +1 WHERE [SalesOrderID] = 43659 GO -- Rebuild the Columnstore Index ALTER INDEX [IX_MySalesOrderDetail_ColumnStore] ON [dbo].[MySalesOrderDetail] REBUILD GO This time it will not throw an error while the update of the table goes successfully. Let us do a cleanup of our tables using this code: -- Cleanup DROP INDEX [IX_MySalesOrderDetail_ColumnStore] ON [dbo].[MySalesOrderDetail] GO TRUNCATE TABLE dbo.MySalesOrderDetail GO DROP TABLE dbo.MySalesOrderDetail GO In the next post we will see how we can use Partition to update the Columnstore Index.

• Healthcare and Distributed Data Don't Mix

  - by [email protected]

  How many times have you heard the story?  Hard disk goes missing, USB thumb drive goes missing, laptop goes missing...Not a week goes by that we don't hear about our data going missing...  Healthcare data is a big one, but we hear about credit card data, pricing info, corporate intellectual property...  When I have spoken at Security and IT conferences part of my message is "Why do you give your users data to lose in the first place?"  I don't suggest they can't have access to it...in fact I work for the company that provides the premiere data security and desktop solutions that DO provide access.  Access isn't the issue.  'Keeping the data' is the issue.We are all human - we all make mistakes... I fault no one for having their car stolen or that they dropped a USB thumb drive. (well, except the thieves - I can certainly find some fault there)  Where I find fault is in policy (or lack thereof sometimes) that allows users to carry around private, and important, data with them.  Mr. Director of IT - It is your fault, not theirs.  Ms. CSO - Look in the mirror.It isn't like one can't find a network to access the data from.  You are on a network right now.  How many Wireless ones (wifi, mifi, cellular...) are there around you, right now?  Allowing employees to remove data from the confines of (wait for it... ) THE DATA CENTER is just plain indefensible when it isn't required.  The argument that the laptop had a password and the hard disk was encrypted is ridiculous.  An encrypted drive tells thieves that before they sell the stolen unit for $75, they should crack the encryption and ascertain what the REAL value of the laptop is... credit card info, Identity info, pricing lists, banking transactions... a veritable treasure trove of info people give away on an 'encrypted disk'.What started this latest rant on lack of data control was an article in Government Health IT that was forwarded to me by Denny Olson, an Oracle Principal Sales Consultant in Minnesota.  The full article is here, but the point was that a couple laptops went missing in a couple different cases, and.. well... no one knows where the data is, and yes - they were loaded with patient info.  What were you thinking?Obviously you can't steal data form a Sun Ray appliance... since it has no data, nor any storage to keep the data on, and Secure Global Desktop allows access from Macs, Linux and Windows client devices...  but in all cases, there is no keeping the data unless you explicitly allow for it in your policy.   Since you can get at the data securely from any network, why would you want to take personal responsibility for it?  Both Sun Rays and Secure Global Desktop are widely used in Healthcare... but clearly not widely enough.We need to do a better job of getting the message out -  Healthcare (or insert your business type here) and distributed data don't mix. Then add Hot Desking and 'follow me printing' and you have something that Clinicians (and CSOs) love.Thanks for putting up my blood pressure, Denny.

• Get to Know a Candidate (9 of 25): Gary Johnson&ndash;Libertarian Party

  - by Brian Lanham

  DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Johnson served as the 29th Governor of New Mexico from 1995 to 2003, as a member of the Republican Party, and is known for his low-tax libertarian views and his strong emphasis on personal health and fitness. While a student at the University of New Mexico in 1974, Johnson sustained himself financially by working as a door-to-door handyman. In 1976 he founded Big J Enterprises, which grew from this one-person venture to become one of New Mexico's largest construction companies. He entered politics for the first time by running for Governor of New Mexico in 1994 on a fiscally conservative, low-tax, anti-crime platform. Johnson won the Republican Party of New Mexico's gubernatorial nomination, and defeated incumbent Democratic governor Bruce King by 50% to 40%. He cut the 10% annual growth in the budget: in part, due to his use of the gubernatorial veto 200 times during his first six months in office, which gained him the nickname "Governor Veto". Johnson sought re-election in 1998, winning by 55% to 45%. In his second term, he concentrated on the issue of school voucher reforms, as well as campaigning for marijuana decriminalization and opposition to the War on Drugs. During his tenure as governor, Johnson adhered to a stringent anti-tax and anti-bureaucracy policy driven by a cost–benefit analysis rationale, setting state and national records for his use of veto powers: more than the other 49 contemporary governors put together. Term-limited, Johnson could not run for re-election at the end of his second term. As a fitness enthusiast, Johnson has taken part in several Ironman Triathlons, and he climbed Mount Everest in May 2003. After leaving office, Johnson founded the non-profit Our America Initiative in 2009, a political advocacy committee seeking to promote policies such as free enterprise, foreign non-interventionism, limited government and privatization. The Libertarian Party is the third largest political party in the United States. It is also identified by many as the fastest growing political party in the United States. The political platform of the Libertarian Party reflects the ideas of libertarianism, favoring minimally regulated markets, a less powerful state, strong civil liberties (including support for Same-sex marriage and other LGBT rights), cannabis legalization and regulation, separation of church and state, open immigration, non-interventionism and neutrality in diplomatic relations (i.e., avoiding foreign military or economic entanglements with other nations), freedom of trade and travel to all foreign countries, and a more responsive and direct democracy. Members of the Libertarian Party have also supported the repeal of NAFTA, CAFTA, and similar trade agreements, as well as the United States' exit from the United Nations, WTO, and NATO. Although there is not an officially labeled political position of the party, it is considered by many to be more right-wing than the Democratic Party but more left-wing than the Republican Party when comparing the parties' positions to each other, placing it at or above the center. In the 30 states where voters can register by party, there are over 282,000 voters registered as Libertarians. Hundreds of Libertarian candidates have been elected or appointed to public office, and thousands have run for office under the Libertarian banner. The Libertarian Party has many firsts in its credit, such as being the first party to get an electoral vote for a woman in a United States presidential election.

• F# and the rose-tinted reflection

  - by CliveT

  We're already seeing increasing use of many cores on client desktops. It is a change that has been long predicted. It is not just a change in architecture, but our notions of efficiency in a program. No longer can we focus on the asymptotic complexity of an algorithm by counting the steps that a single core processor would take to execute it. Instead we'll soon be more concerned about the scalability of the algorithm and how well we can increase the performance as we increase the number of cores. This may even lead us to throw away our most efficient algorithms, and switch to less efficient algorithms that scale better. We might even be willing to waste cycles in order to speculatively execute at the algorithm rather than the hardware level. State is the big headache in this parallel world. At the hardware level, main memory doesn't necessarily contain the definitive value corresponding to a particular address. An update to a location might still be held in a CPU's local cache and it might be some time before the value gets propagated. To get the latest value, and the notion of "latest" takes a lot of defining in this world of rapidly mutating state, the CPUs may well need to communicate to decide who has the definitive value of a particular address in order to avoid lost updates. At the user program level, this means programmers will need to lock objects before modifying them, or attempt to avoid the overhead of locking by understanding the memory models at a very deep level. I think it's this need to avoid statefulness that has led to the recent resurgence of interest in functional languages. In the 1980s, functional languages started getting traction when research was carried out into how programs in such languages could be auto-parallelised. Sadly, the impracticality of some of the languages, the overheads of communication during this parallel execution, and rapid improvements in compiler technology on stock hardware meant that the functional languages fell by the wayside. The one thing that these languages were good at was getting rid of implicit state, and this single idea seems like a solution to the problems we are going to face in the coming years. Whether these languages will catch on is hard to predict. The mindset for writing a program in a functional language is really very different from the way that object-oriented problem decomposition happens - one has to focus on the verbs instead of the nouns, which takes some getting used to. There are a number of hybrid functional/object languages that have been becoming more popular in recent times. These half-way houses make it easy to use functional ideas for some parts of the program while still allowing access to the underlying object-focused platform without a great deal of impedance mismatch. One example is F# running on the CLR which, in Visual Studio 2010, has because a first class member of the pack. Inside Visual Studio 2010, the tooling for F# has improved to the point where it is easy to set breakpoints and watch values change while debugging at the source level. In my opinion, it is the tooling support that will enable the widespread adoption of functional languages - without this support, people will put off any transition into the functional world for as long as they possibly can. Without tool support it will make it hard to learn these languages. One tool that doesn't currently support F# is Reflector. The idea of decompiling IL to a functional language is daunting, but F# is potentially so important I couldn't dismiss the idea. As I'm currently developing Reflector 6.5, I thought it wise to take four days just to see how far I could get in doing so, even if it achieved little more than to be clearer on how much was possible, and how long it might take. You can read what happened here, and of the insights it gave us on ways to improve the tool.

• St. Louis ALT.NET

  - by Brian Schroer

  I’m a huge fan of the St. Louis .NET User Group and a regular attendee of their meetings, but always wished there was a local group that discussed more advanced .NET topics. (That’s not a criticism of the group - I appreciate that they want to server developers with a broad range of skill levels). That’s why I was thrilled when Nicholas Cloud started a St. Louis ALT.NET group in 2010. Here’s the “about us” statement from the group’s web site: The ALT.NET community is a loosely coupled, highly cohesive group of like-minded individuals who believe that the best developers do not align themselves with platforms and languages, but with principles and ideas. In 2007, David Laribee created the term "ALT.NET" to explain this "alternative" view of the Microsoft development universe--a view that challenged the "Microsoft-only" approach to software development. He distilled his thoughts into four key developer characteristics which form the basis of the ALT.NET philosophy: You're the type of developer who uses what works while keeping an eye out for a better way. You reach outside the mainstream to adopt the best of any community: Open Source, Agile, Java, Ruby, etc. You're not content with the status quo. Things can always be better expressed, more elegant and simple, more mutable, higher quality, etc. You know tools are great, but they only take you so far. It's the principles and knowledge that really matter. The best tools are those that embed the knowledge and encourage the principles (e.g. Resharper.) The St. Louis ALT.NET meetup group is a place where .NET developers can learn, share, and critique approaches to software development on the .NET stack. We cater to the highest common denominator, not the lowest, and want to help all St. Louis .NET developers achieve a superior level of software craftsmanship. I don’t see a lot of ALT.NET talk in blogs these days. The movement was harmed early on by the negative attitudes of some of its early leaders, including jerk moves like the Entity Framework “vote of no confidence”, but I do see occasional mentions of local groups like the St. Louis one. I think ALT.NET has been successful at bringing some of its ideas into the .NET world, including heavily influencing ASP.NET MVC and raising the general level of software craftsmanship for developers working on the Microsoft stack. The ideas and ideals live on, they’re just not branded as “this is ALT.NET!” In the past 18 months, St. Louis ALT.NET meetups have discussed topics like: NHibernate F# and other functional languages AOP CoffeeScript “How Ruby Is Making Me a Stronger C# Developer” Using rake for builds CQRS .NET dynamic programming micro web frameworks – Nancy & Jessica Git ALT.NET doesn’t mean (to me, anyway) “alternatives to .NET”, but “alternatives for .NET”. We look at how things are done in Ruby and other languages/platforms, but always with the idea “What can I learn from this to take back to my “day job” with .NET?”. Meetings are held at 7PM on the fourth Wednesday of each month at the offices of Professional Employment Group. PEG is located at 999 Executive Parkway (Suite 100 – lower level) in Creve Coeur (South of Olive off of Mason Road - Here's a map). Food is not supplied (sorry if you’re a big fan of the Papa John’s Crust-Lovers’ Pizza that’s a staple of user group meetings), but attendees are encouraged to come early and bring/share beer, so that’s cool. Thanks to Nick for organizing, and to Professional Employment Group for lending their offices. Please visit the meetup site for more information.

• Ongoing confusion about ivars and properties in objective C

  - by Earl Grey

  After almost 8 months being in ios programming, I am again confused about the right approach. Maybe it is not the language but some OOP principle I am confused about. I don't know.. I was trying C# a few years back. There were fields (private variables, private data in an object), there were getters and setters (methods which exposed something to the world) ,and properties which was THE exposed thing. I liked the elegance of the solution, for example there could be a class that would have a property called DailyRevenue...a float...but there was no private variable called dailyRevenue, there was only a field - an array of single transaction revenues...and the getter for DailyRevenue property calculated the revenue transparently. If somehow the internals of daily revenue calculation would change, it would not affect somebody who consumed my DailyRevenue property in any way, since he would be shielded from getter implementation. I understood that sometimes there was , and sometimes there wasn't a 1-1 relationship between fields and properties. depending on the requirements. It seemed ok in my opinion. And that properties are THE way to acces the data in object. I know the difference betweeen private, protected, and public keyword. Now lets get to objectiveC. On what factor should I base my decision about making someting only an ivar or making it as a property? Is the mental model the same as I describe above? I know that ivars are "protected" by default, not "private" asi in c#..But thats ok I think, no big deal for my presnet level of understanding the whole ios development. The point is ivars are not accesible from outside (given i don't make them public..but i won't). The thing that clouds my clear understanding is that I can have IBOutlets from ivars. Why am I seeing internal object data in the UI? *Why is it ok?* On the other hand, if I make an IBOutlet from property, and I do not make it readonly, anybody can change it. Is this ok too? Let's say I have a ParseManager object. This object would use a built in Foundation framework class called NSXMLParser. Obviously my ParseManager will utilize this nsxmlparser's capabilities but will also do some additional work. Now my question is, who should initialize this NSXMLParser object and in which way should I make a reference to it from the ParseManager object, when there is a need to parse something. A) the ParseManager -1) in its default init method (possible here ivar - or - ivar+ppty) -2) with lazyloading in getter (required a ppty here) B) Some other object - who will pass a reference to NSXMLParser object to the ParseManager object. -1) in some custom initializer (initWithParser:(NSXMLPArser *) parser) when creating the ParseManager object.. A1 - the problem is, we create a parser and waste memory while it is not yet needed. However, we can be sure that all methods that are part ot ParserManager object, can use the ivar safely, since it exists. A2 - the problem is, the nsxmlparser is exposed to outside world, although it could be read only. Would we want a parser to be exposed in some scenario? B1 - this could maybe be useful when we would want to use more types of parsers..i dont know... I understand that architectural requirements and and language is not the same. But clearly the two are in relation. How to get out of that mess of my? Please bear with me, I wasn't able to come up with a single ultimate question. And secondly, it's better to not scare me with some superadvanced newspeak that talks about some crazy internals (what the compiler does) and edge cases.

• Using the SOA-BPM VIrtualBox Appliance

  - by antony.reynolds

  Quickstart Guide to Using Oracle Appliance for SOA/BPM Recently I have been setting up some machines for fellow engineers.  My base setup consists of Oracle Enterprise Linux with Oracle Virtual Box.  Note that after installing VirtualBox I needed to add the VirtualBox Extension Pack to enable RDP access amongst other features.  In order to get them started quickly with some images I downloaded the pre-built appliance for SOA/BPM from OTN. Out of the box this provides a VirtualBox image that is pre-installed with everything you will need to develop SOA/BPM applications. Specifically by using the virtual appliance I got the following pre-installed and configured. Oracle Enterprise Linux 5 User oracle password oracle User root password oracle. Oracle Database XE Pre-configured with SOA/BPM repository. Set to auto-start on OS startup. Oracle SOA Suite 11g PS2 Configured with a “collapsed domain”, all services (SOA/BAM/EM) running in AdminServer. Listening on port 7001 Oracle BPM Suite 11g Configured in same domain as SOA Suite. Oracle JDeveloper 11g With SOA/BPM extensions. Networking The VM by default uses NAT (Network Address Translation) for network access.  Make sure that the advanced settings for port forwarding allow access through the host to guest ports.  It should be pre-configured to forward requests on the following ports Purpose Host Port Guest Port (VBox Image) SSH 2222 22 HTTP 7001 7001 Database 1521 1521 Note that only one VirtualBox image can use a given host port, so make sure you are not clashing if it seems not to work. What’s Left to Do? There is still some customization of the environment that may be required. If you need to configure a proxy server as I did then for the oracle and root users to set up an HTTP proxy Added “export http_proxy=http://proxy-host:proxy-port” to ~oracle/.bash_profile and ~root/.bash_profile Added “export http_proxy=http://proxy-host:proxy-port” to /etc/.bashrc Edited System->Preferences to set Network Proxy In Firefox set Preferences->Network->Connection Settings to “Use system proxy settings” In JDeveloper set Edit->Preferences->Web Browser and Proxy to required proxy settings You may need to configure yum to point to a public OEL yum repository – such as http://public-yum.oracle.com. If you are going to be accessing the SOA server from outside the VirtualBox image then you may want to set the soa-infra Server URLs to be the hostname of the host OS. Snap! Once I had the machine configured how I wanted to use it I took a snapshot so that I can always get back to the pristine install I have now.  Snapshots are one of the big benefits of putting a development environment into a virtualized environment.  I can make changes to my installation and if I mess it up I can restore the image to a last known good snapshot. Hey Presto!, Ready to Go This is the quickest way to get up and running with SOA/BPM Suite.  Out of the box the download will work, I only did extra customization so I could use services outside the firewall and browse outside the firewall from within by SOA VirtualBox image.  I also use yum to update the OS to the latest binaries. So have fun.

• Increasing touch surface (#wp7dev)

  - by Laurent Bugnion

  When you design for Windows Phone 7 (or for any touch device, for that matter, and most especially small screens), you need to be very careful to give enough surface to your users’ fingers. It is easy to miss a touch on such small screens, and that can be horrifyingly frustrating. This is especially true when people are on the move, and trying to hit the control while walking and holding their device in one hand, or when the device is mounted in a car and vibrating with the engine. In my experience, a touch surface should be ideally minimum 60x60 pixels to be easy to activate on the Windows Phone 7 screen (which is, as we know, 800 pixels x 480 pixels). Ideally, I try to make my touch surfaces 80x80 pixels minimum. This causes a few design challenges of course. Using transparent backgrounds However, one thing is helping us tremendously: some surfaces can be made transparent, and yet react to touch. The secret is the following: If you have a panel that has a Null background (i.e. the Background is not set at all), then the empty surface does not react to touch. If however the Background is set to the Transparent color (or any color where the Alpha channel is set to 0), then it will react to touch. Setting a transparent background is easy. For example: <Grid Background="#00000000"> </Grid> or <Grid Background="Transparent"> </Grid> In C#: var grid = new Grid { Background = new SolidColorBrush( Colors.Transparent) }; Using negative margins Having a transparent background reactive to touch is a good start, but in addition, you must make sure that the surface is big enough for my clumsy fingers. One way to achieve that is to increase the transparent, touch-reactive surface, and reposition the element using negative margins. For example, consider the following UI. I changed the transparent background of the HyperlinkButton to Red, in order to visualize the touch surface. In this figure, the Settings HyperlinkButton is 105 pixels x 31 pixels. This is wide enough, but really small in height and easy to miss. To improve this, we can use negative margins, for instance: <HyperlinkButton Content="Settings" HorizontalAlignment="Right" VerticalAlignment="Bottom" Height="60" Margin="0,0,0,-15" /> Notice the usage of negative bottom margin to bring the HyperlinkButton back at the bottom of the main Grid’s first row, where it belongs. And the result is: Notice how the touch surface is much bigger than before. This makes the HyperlinkButton easier to reach, and improves the user experience. With the background set back to normal, the UI looks exactly the same, as it should: In summary: Remember to maximize the touch surface for your controls. Plan your design in consequence by reserving enough room around each control to allow their hit surface to be expanded as shown in this article. Do not cram too many controls in one page. If REALLY needed, use an additional page (or even better: use a Pivot control with multiple pivot items) for the controls that don’t fit on the first one. This should ensure a smoother user experience and improved touch behavior. Happy coding! Laurent   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• Stuck due to "knowing too much"

  - by Ran Biron

  Note more discussion at http://news.ycombinator.com/item?id=4037794 Welcome Hacker News Visitors! While HN is a fine forum for discussion and debate, Programmers - Stack Exchange is not. From the FAQ: If your motivation for asking the question is “I would like to participate in a discussion about ____”, then you should not be asking here. However, if your motivation is “I would like others to explain ____ to me”, then you are probably OK. (Discussions are of course welcome in our real time web chat.) Currently, this question is viewed by the membership of Programmers.SE as more likely to provoke unproductive discussion than constructive answers; while debates on its form and future are conducted, it will be locked to prevent arguments and vandalism. -- Shog9 I have a relatively simple development task, but every time I try to attack it, I end up spiraling in deep thoughts - how could it extending the future, what are the 2nd generation clients going to need, how does it affect "non functional" aspects (e.g. Performance, authorization...), how would it best be architectured to allow change... I remember myself a while ago, younger and, perhaps, more eager. The "me" I was then wouldn't have given a thought about all that - he would've gone ahead and wrote something, then rewrote it, then rewrote it again (and again...). The "me" today is more hesitant, more careful. I find it much easier today to sit and plan and instruct other people on how to do things than to actually go ahead and do them myself - not because I don't like to code - the opposite, I love to! - but because every time I sit at the keyboard, I end up in that same annoying place. Is this wrong? Is this a natural evolution, or did I drive myself into a rut? Fair disclosure - in the past I was a developer, today my job title is a "system architect". Good luck figuring what it means - but that's the title. Wow. I honestly didn't expect this question to generate that many responses. I'll try to sum it up. Reasons: Analysis paralysis / Over engineering / gold plating / (any other "too much thinking up-front can hurt you"). Too much experience for the given task. Not focusing on what's important. Not enough experience (and realizing that). Solutions (not matched to reasons): Testing first. Start coding (+ for fun) One to throw away (+ one API to throw away). Set time constraints. Strip away the fluff, stay with the stuff. Make flexible code (kinda opposite to "one to throw away", no?). Thanks to everyone - I think the major benefit here was to realize that I'm not alone in this experience. I have, actually, already started coding and some of the too-big things have fallen off, naturally. Since this question is closed, I'll accept the answer with most votes as of today. When/if it changes - I'll try to follow.

• SQLAuthority News – Learning Never Ends – Becoming Student Again

  - by pinaldave

  From my past few blog posts you may see a pattern – learning.  I finished my own college education a few years ago, but I firmly believe that learning should never stop.  We can learn on the job, or from outside reading, but we should always try to be learning new things.  It keeps the brain sharp!  In fact, I often find myself learning new things from reviewing old material.  If you have been reading my blog lately, you will recognize the name Koenig Solutions. You might also be rolling your eyes at me and my enthusiasm for learning and training.  College was hard work, why continue it?  Didn’t we all get educations so that we could get jobs and go on vacation? Of course, having a job means that you cannot take vacations all the time.  I have often asked my friend who owns Koenig, jokingly, when he is going to open a Koenig center in Bangalore. I relocated to Bangalore 1.5 years ago, so I wanted a center I could walk to anytime.  Last week I was very happy to hear that they have opened a center in Bangalore. Pinal Dave at Friend’s Company I could not let a new center open without visiting it and congratulating my friend, so I recently stopped by.  I was immediately taken by the desire to go back to “school” and learn something new.  I have signed up to take a continuing education course through the new Koenig center and here is the exciting part: I will be blogging about it so that you all can be inspired to learn, too!  Keep checking back here for further updates and blog posts about my learning experience. However, what is the fun to attend the session in the town where you stay. I indeed visited their center in Bangalore but I have opted to learn the course in another city. Well, more information about the same in near future. Pinal Dave is going to be a student again Honestly, why not learn new things and become more confident?  When we have more education we will become better at our jobs, which can lead to more confidence and efficiency, but may also have more physical rewards – like a raise or promotion.  We don’t always have to focus on shallow rewards like money and recognition, so think about how much more you will enjoy your work when you know more about it.  Koenig is offering training for new certificates in SQL Server 2012, and I am planning on investigating these for sure. I feel good that I am going to be a student again and will be learning new stuff. As I said I will blog my experience as I go. I hope that my continuing education blog posts will inspire you, my readers, to go out and learn more.  I am serious about my education and my goal is to prove how serious I am here, on my blog. I am a big fan of Learning and Sharing and I hope this series will inspire you to learn new technology which can help you progress in your career and help balance your life with work. Note: This blog post is about what inspired me to sign up for learning course. Becoming student should be the attitude of a lifetime. This post is not about a career change.

• Surface V2.0

  - by Dennis Vroegop

  It’s been quiet around here. And the reason for that is that it’s been quiet around Surface for a while. Now, a lot of people assume that when a product team isn’t making too much noise that must mean they stopped working on their product. Remember the PDC keynote in 2010? Just because they didn’t mention WPF there a lot of people had the idea that WPF was dead and abandoned for Silverlight. Of course, this couldn’t be farther from the truth. The same applies to Surface. While we didn’t hear much from the team in Redmond they were busy putting together the next version of the platform. And at the CES in January the world saw what they have been up to all along: Surface V2.0 as it’s commonly known. Of course, the product is still in development. It’s not here yet, we can’t buy one yet. However, more and more information comes available and I think this is a good time to share with you what it’s all about! The biggest change from an organizational point of view is that Microsoft decided to stop producing the hardware themselves. Instead, they have formed a partnership with Samsung who will manufacture the devices. This means that you as a buyer get the benefits of a large, worldwide supplier with all the services they can offer. Not that Microsoft didn’t do that before but since Surface wasn’t a ‘big’ product it was sometimes hard to get to the right people. The new device is officially called the “Samsung SUR 40 for Microsoft Surface” which is quite a mouthful. The software that runs the device is of course still coming from Microsoft. Let’s dive into the technical specs (note: all of this is preliminary, it’s still in the Alpha phase!): Audio out HDMI / StereoRCA / SPDIF / 2 times 3.5mm audio out jack Brightness 300 CD/m2 Communications 1GB Ethernet/802.11/Bluetooth Contrast Ratio 1:1000 CPU AMD Athlon X2 245e 2.9Ghz Dual Core Display Resolution Full HD 1080p 1920x1080 / 16:9 aspect ratio GPU AMD Radeon HD 6750 1GB GDDRS HDD 320 GB / 7200 RPM HDMI In / HDMI out Yes I/O Ports 4 USB, SD Card reader Operation System Embedded Windows 7 Professional 64 bits Panel Size 40” diagonal Protection Glass Gorilla Glass RAM 4 GB DD3 Weight / with standard legs 70.0 Kg / 154 lbs Weight / standalone 39.5 Kg / 87 lbs Height (without legs) 4 inch Contact points recognized > 50 Cool Factor Extremely   Ok, the last point is not official, but I do think it needs to be there. Let’s talk software. As noted, it runs Windows 7 Professional 64 bit, which means you can run Visual Studio 2010 on it. The software is going to be developed in WPF4.0 with the additional Surface SDK 2.0. It will contain all the things you’ve seen before plus some extra’s. They have taken some steps to align it more with the Surface Toolkit which you can download today, so if you do things right your software should be portable between a WPF4.0 Windows 7 Multi-touch app and the Surface v2 environment. It still uses infrared to detect contacts, so in that respect nothing much has changed conceptually. We still can differentiate between a finger, a tag or a blob. Of course, since the new platform has a much higher resolution (compared to the 1024x768 of the first version) you might need to look at your code again. I’ve seen a lot of applications on Surface that assume the old resolution and moving that to V2 is going to be some work. To be honest: as I am under NDA I cannot disclose much about the new software besides what I have told you here, but trust me: it’s going to blow people away. Now, the biggest question for me is: when can I get one? Until we can, have a look here: Tags van Technorati: surface,samsung,WPF

• Oracle WebCenter: Common User Experience Architecture

  - by kellsey.ruppel(at)oracle.com

  You may remember that the key goals of the new release of WebCenter are providing a Modern User Experience, unparalleled Application Integration, converging all the best of the existing portal platforms into WebCenter and delivering a Common User Experience Architecture.  In previous weeks we've provided an overview of Oracle WebCenter and discussed some of the other key goals and this week, we'll focus on how the new release of Oracle WebCenter delivers a Common User Experience Architecture.When Oracle talks about a Common User Experience Architecture, it really focuses on a core set of areas.  First, the way that information is accessed needs to be consistent and extensible so that as requirements change, the applications don't need to be rewritten for every change. Second, this information access layer needs to be securely accessible to any application, site, or any other channel that needs to leverage this information.  Third, there needs to be a consistent presentation layout, Oracle calls it a UI shell, so that all resources can fit together in a useable, productive way.  Fourth, there needs to be a common set of design patterns for how different menus, features, and services fit into this UI Shell for broad and productive usability.  Fifth, there needs to be a set of design patterns for the individual services that plug into this UI shell so that end users can move from one module of the application to another without new learning.  Finally, all of these layers need to be customizable in an easy way that insulates IT from patching and upgrading problems and allows the business owners the agility to quickly change with the market conditions.As Oracle has already announced, we will release our next generation of enterprise applications called Oracle Fusion Applications.  We have thousands of developers building these applications that all had different programming tool experience and UI design experience.  We've educated over 6,000 developers building Oracle Fusion Applications to leverage these Common User Experience Architecture patterns to speed their learning curve of the new Java standards as well as SOA principles to deliver a revolutionary new set of applications.  You could imagine the big challenge with getting all these developers with different backgrounds and different UI design skills to deliver a completely integrated application user experience.  This is why Oracle invested heavily in designing this Common User Experience Architecture, based on Oracle WebCenter and the Oracle Application Development Framework (ADF).  It pulls together the best practices and design patterns that Oracle development required in order to bring Fusion Applications to market and Oracle WebCenter is the user experience layer that all of this is surfaced through.  In this way, customers can quickly brand a deployment for new partnerships without having to redevelop a new site.  Or they can quickly add new options to the UI Shell to enable their line of business managers to quickly adapt to a new competitive product.  And with the core integration of the activities to produce a Business Activity Stream, customers are able to stay on top of all their key business actions when they happen as they happen and more importantly, the system can recommend actions or resources to help act on these activities.And we've authored this whole set of design patterns for Oracle development to take advantage of in delivering Fusion Applications.  We're also applying these design patterns to our existing eBusiness Suite, Peoplesoft, Siebel, and JD Edwards applications so that they can tie in the exact same way that Fusion Applications has been brought together.  This will provide customers with a complete Common User Experience Architecture for their entire ecosystem of applications within their enterprise whether they are from Oracle, another vender, or custom built applications. And this is all provided in the new release of Oracle WebCenter.  These design patterns cover elements around delivering a complete, aggregated menu of all the capabilities that their role allows independent of which application they are trying to access.   It means that as they move from one application to another, they will have a consistent user experience.  And if they are using an Oracle application, any customizations that are made to the application are preserved and managed through upgrades and patches.Be sure to check back this week as we share more information and resources on Oracle's Common User Experience Architecture.

• Why I&rsquo;m Getting an iPad

  - by andrewbrust

  I have never purchased an Apple product in my life.  That’s a “true fact.”  And, for that matter, the last Apple product I really wanted was an Apple IIe, back in the 1980s.  I couldn’t afford it though (I was in high school), so I got a Commodore 64 instead…it had the same microprocessor, after all.  If the iPhone were on Verizon, I probably would have picked one up in December, when I got my Droid.  And if the iPod Touch worked with my Napster subscription (which of course it does not, but my Sonos does) I might have picked on of those instead. That’s three strikes, but Apple’s not out.  I’ve decided I want the iPad.  Why?  Well, to start with, my birthday is March 31st…the iPad comes out on April 3rd, and my wife wanted to know what to get me.  Also, my house is a 7-minute walk from the Apple Store on West 14th Street in Manhattan.  This makes it easy to get my pre-ordered device on launch day, and get home quickly with it.  Oh, and I agreed to write an article for Redmond Magazine, the fee for which will pay for the device…that way the birthday present doesn’t have to be an extravagant expense.  Plus, I’m a contrarian, so I want to buy the one device from Apple that the fanboys have actually panned. Think those are bad reasons? How about this: I want to experience iPhone and iPad development and, although my app will probably never hit the App Store and run on the actual device, I still think owning one will help me develop something better.  i want to see if the slate form factor has good business usage scenarios.  I want to see if Business Intelligence technology on a device like this can work.  Imagine a dashboard on this thing. And, for the consumer experience, I really want a touch device on which I can surf the Web while I’m in the kitchen, or on the couch.  I don’t want the small form factor of my phone, I don’t want to use my TV, and I don’t want a keyboard that will get dirty or in my way. I don’t want to watch movies on it (my TV is good for that), so I don’t care that the iPad has a 4:3 screen.  I don’t want to read books on it, so I don’t care that the display is backlit LCD, rather than eInk. But really what I want is to understand, first hand, why people have such brand loyalty to Apple.  I know the big reasons; I’m not detached from society.  But I want to know the subtle points of what Apple does really well, and also what they do poorly.  And I’d like to know, once and for all, if Microsoft can beat Apple, if Microsoft can think the right way to beat Apple and if Microsoft should  even try to beat Apple. I expect to share my thoughts on these questions, as they develop.

• SQL SERVER – Basic Calculation and PEMDAS Order of Operation

  - by pinaldave

  After thinking a long time, I have decided to write about this blog post. I had no plan to create a blog post about this subject but the amount of conversation this one has created on my Facebook page, I decided to bring up a few of the question and concerns discussed on the Facebook page. There are more than 10,000 comments here so far. There are lots of discussion about what should be the answer. Well, as far as I can tell there is a big debate going on on Facebook, for educational purpose you should go ahead and read some of the comments. They are very interesting and for sure teach some new stuff. Even though some of the comments are clearly wrong they have made some good points and I believe it for sure develops some logic. Here is my take on this subject. I believe the answer is 9 as I follow PEMDAS  Order of Operation. PEMDAS stands for  parentheses, exponents, multiplication, division, addition, subtraction. PEMDAS is commonly known as BODMAS in India. BODMAS stands for Brackets, Orders (ie Powers and Square Roots, etc), Division, Multiplication,  Addition and Subtraction. PEMDAS and BODMAS are almost same and both of them follow the operation order from LEFT to RIGHT. Let us try to simplify above statement using the PEMDAS or BODMAS (whatever you prefer to call). Step 1: 6 ÷ 2 (1+2) (parentheses first) Step 2: = 6 ÷ 2 * (1+2) (adding multiplication sign for further clarification) Step 3: = 6 ÷ 2* (3) (single digit in parentheses – simplify using operator) Step 4: = 6 ÷ 2 * 3 (Remember next Operation should be LEFT to RIGHT) Step 5: = 3 * 3 (because 6 ÷ 2 = 3; remember LEFT to RIGHT) Step 6: = 9 (final answer) Some often find Step 4 confusing and often ended up multiplying 2 and 3 resulting Step 5 to be 6 ÷ 6, this is incorrect because in this case we did not follow the order of LEFT to RIGHT. When we do not follow the order of operation from LEFT to RIGHT we end up with the answer 1 which is incorrect. Let us see what SQL Server returns as a result. I executed following statement in SQL Server Management Studio SELECT 6/2*(1+2) It is clear that SQL Server also thinks that the answer should be 9. Let us go ahead and ask Google what will be the answer of above question in Google I have searched for the following term: 6/2(1+2) The result also says the answer should be 9. If you want a further reference here is a great video which describes why the answer should be 9 and not 1. And here is a fantastic conversation on Google Groups. Well, now what is your take on this subject? You are welcome to share constructive feedback and your answer may be different from my answer. NOTE: A healthy conversation about this subject is indeed encouraged but if there is a single bad word or comment is flaming it will be deleted without any notification (it does not matter how valuable information it contains).

• Are there too many qualified software development engineers chasing too few jobs?

  - by T Gregory

  I am trying to write this question in a non-argumentative way, but it is quite emotionally charged for some, so please bear with me. In the U.S., we hear constantly from CEOs that they cannot find enough qualified software engineers. In fact, it is the position of the U.S. government that demand for software engineering talent outpaces supply. This position can be clearly seen in the granting of tens of thousands of H1B visas, but also in the following excerpt from the official 2010-11 Bureau of Labor Statistics Occupational Outlook Handbook: Employment of computer software engineers is expected to increase by 32 percent from 2008-2018, which is much faster than the average for all occupations. In addition, this occupation will see a large number of new jobs, with more than 295,000 created between 2008 and 2018. Demand for computer software engineers will increase as computer networking continues to grow. For example, expanding Internet technologies have spurred demand for computer software engineers who can develop Internet, intranet, and World Wide Web applications. Likewise, electronic data-processing systems in business, telecommunications, healthcare, government, and other settings continue to become more sophisticated and complex. Implementing, safeguarding, and updating computer systems and resolving problems will fuel the demand for growing numbers of systems software engineers. New growth areas will also continue to arise from rapidly evolving technologies. The increasing uses of the Internet, the proliferation of Web sites, and mobile technology such as the wireless Internet have created a demand for a wide variety of new products. As more software is offered over the Internet, and as businesses demand customized software to meet their specific needs, applications and systems software engineers will be needed in greater numbers. In addition, the growing use of handheld computers will create demand for new mobile applications and software systems. As these devices become a larger part of the business environment, it will be necessary to integrate current computer systems with this new, more mobile technology. However, from the the employee side of the equation, we often hear the opposite. Many of the stories of SDEs with graduate degrees and decades of experience on the unemployment line, or the big tech interview war stories, are anecdotal, for sure. But, there is one piece of data that is neither anecdotal nor transitory, and that is the aggregate decisions of millions of undergraduates of what degree to pursue. Here, a different picture emerges from the data, and that picture is not good for the software profession. According the most recent Taulbee Survey from Computer Research Association, undergrad degree production in CS and CE has fallen nearly 60% since 2004. (Undergrad enrollments have ticked up in the past two years, but only modestly). Here we see that a basic disconnect between what corporate CEOs and the US government are saying and what potential employees really think about job prospects in software engineering. So my questions are these. Who are we to believe? Is there an acute talent shortage, or is there a long-term structural oversupply in the SDE labor market? Can anyone provide reliable data on long-term unemployment among SDEs? How many are leaving the profession due to lack of work? Real data is most helpful. Thanks.

• FairWarning Privacy Monitoring Solutions Rely on MySQL to Secure Patient Data

  - by Rebecca Hansen

  FairWarning® solutions have audited well over 120 billion events, each of which was processed and stored in a MySQL database. FairWarning is the world's leading supplier of privacy monitoring solutions for electronic health records, relied on by over 1,200 Hospitals and 5,000 Clinics to keep their patients' data safe. In January 2014, FairWarning was awarded the highest commendation in healthcare IT as the first ever Category Leader for Patient Privacy Monitoring in the "2013 Best in KLAS: Software & Services" report[1]. FairWarning has used MySQL as their solutions’ database from their start in 2005 to worldwide expansion and market leadership. FairWarning recently migrated their solutions from MyISAM to InnoDB and updated from MySQL 5.5 to 5.6. Following are some of benefits they’ve had as a result of those changes and reasons for their continued reliance on MySQL (from FairWarning MySQL Case Study). Scalability to Handle Terabytes of Data FairWarning's customers have a lot of data: On average, FairWarning customers receive over 700,000 events to be processed daily. Over 25% of their customers receive over 30 million events per day, which equates to over 1 billion events and nearly one terabyte (TB) of new data each month. Databases range in size from a few hundred GBs to 10+ TBs for enterprise deployments (data are rolled off after 13 months). Low or Zero Admin = Few DBAs "MySQL has not required a lot of administration. After it's been tuned, configured, and optimized for size on initial setup, we have very low administrative costs. I can scale and add more customers without adding DBAs. This has had a big, positive impact on our business.” - Chris Arnold, FairWarning Vice President of Product Management and Engineering. Performance Schema  As the size of FairWarning's customers has increased, so have their tables and data volumes. MySQL 5.6’ new maintenance and management features have helped FairWarning keep up. In particular, MySQL 5.6 performance schema’s low-level metrics have provided critical insight into how the system is performing and why. Support for Mutli-CPU Threads MySQL 5.6' support for multiple concurrent CPU threads, and FairWarning's custom data loader allow multiple files to load into a single table simultaneously vs. one at a time. As a result, their data load time has been reduced by 500%. MySQL Enterprise Hot Backup Because hospitals and clinics never stop, FairWarning solutions can’t either. FairWarning changed from using mysqldump to MySQL Enterprise Hot Backup, which has reduced downtime, restore time, and storage requirements. For many of their larger customers, restore time has decreased by 80%. MySQL Enterprise Edition and Product Roadmap Provide Complete Solution "MySQL's product roadmap fully addresses our needs. We like the fact that MySQL Enterprise Edition has everything included; there's no need to purchase separate modules."  - Chris Arnold Learn More>> FairWarning MySQL Case Study Why MySQL 5.6 is an Even Better Embedded Database for Your Products presentation Updating Your Products to MySQL 5.6, Best Practices for OEMs on-demand webinar (audio and / or slides + Q&A transcript) MyISAM to InnoDB – Why and How on-demand webinar (same stuff) Top 10 Reasons to Use MySQL as an Embedded Database white paper [1] 2013 Best in KLAS: Software & Services report, January, 2014. © 2014 KLAS Enterprises, LLC.

• Implementing features in an Entity System

  - by Bane

  After asking two questions on Entity Systems (1, 2), and reading some articles on them, I think that I understand them much better than before. But, I still have some uncertainties, and mainly they are about building a Particle Emitter, an Input system, and a Camera. I obviously still have some problems understanding Entity Systems, and they might apply to a whole other range of objects, but I chose these three because they are very different concepts and should cover a pretty big ground, and help me understand Entity Systems and how to handle problems like these myself, as they come along. I am building an engine in Javascript, and I've implemented most of the core features, which include: input handling, flexible animation system, particle emitter, math classes and functions, scene handling, a camera and a render, and a whole bunch of other things that engines usually support. Then, I read Byte56's answer that got me interested into making the engine into an Entity System one. It would still remain an HTML5 game engine with the basic Scene philosophy, but it should support dynamic creation of entities from components. These are some of the definitions from the previous questions, updated: An Entity is an identifier. It doesn't have any data, it's not an object, it's a simple id that represents an index in the Scene's list of all entities (which I actually plan to implement as a component matrix). A Component is a data holder, but with methods that can operate on that data. The best example is a Vector2D, or a "Position" component. It has data: x and y, but also some methods that make operating on the data a bit easier: add(), normalize(), and so on. A System is something that can operate on a set of entities that meet the certain requirements, usually they (the entities) need to have a specified (by the system itself) set of components to be operated upon. The system is the "logic" part, the "algorithm" part, all the functionality supplied by components is purely for easier data management. The problem that I have now is fitting my old engine concept into this new programming paradigm. Lets start with the simplest one, a Camera. The camera has a position property (Vector2D), a rotation property and some methods for centering it around a point. Each frame, it is fed to a renderer, along with a scene, and all the objects are translated according to it's position. Then the scene is rendered. How could I represent this kind of an object in an Entity System? Would the camera be an entity or simply a component? A combination (see my answer)? Another issues that is bothering me is implementing a Particle Emitter. For what exactly I mean by that, you can check out my video of it: http://youtu.be/BObargIMQsE. The problem I have with this is, again, what should be what. I'm pretty sure that particles themselves shouldn't be entities, as I want to support 10k+ of them, and creating that much entities would be a heavy blow on my performance, I believe. Or maybe not? Depends on the implementation, but anyone with experience: please, do answer. The last bit I wan't to talk about, which is also bugging me the most, is how input should be handled. In my current version of the engine, there is a class called Input. It's a handler that subscribes to browser's events, such as keypresses, and mouse position changes, and also it maintains an internal state. Then, the player class has a react() method, which accepts an input object as an argument. The advantage of this is that the input object could be serialized into JSON and then shared over the network, allowing for smooth multiplayer simulations. But how does this translate into an Entity System?
