• How can I get my progress reviewed as a solo junior developer

  - by Oliver Hyde

  I am currently working for a 2 person company, as the solo primary developer. My boss gets the clients, mocks up some png design templates and hands them over to me. This system has been working fine and i'm really enjoying it. The types of projects I work on are for small - medium sized businesses and they usually want a CMS system. Developed from scratch i'll build a customised backend for the client to add/edit/remove categories, tags, products etc and then output them to the front end according to the design template handed to me. As time has gone on, the projects have increased in complexity, with shopping cart / ordering features and other common e-commerce type features. Again, this system has been working fine and i'm really enjoying it. My issue is my personal development as a programmer. I spend a lot of my spare time reading programming blogs, checking through stackexchange, reading suggested programming books (currently on 'The Pragmatic Programmer', really good so far), doing brain exercises (lumosity.com and khanacademy math problems), doing lots of physical exercise and other personal development type activities. I can't help but feel though, that I'm missing out on feedback, critique. My boss is great and never holds back on praise in regards to my work, but he unfortunately is either to busy to check my code, or to be honest, I don't think it's one of his specialties and so can't provide feedback. I want to know what i'm doing wrong and what i'm doing right. Should I be putting that much logic in the controller, am I modulating my code enough etc. So what I have done is developed a little 'Family Budgeting' app and tried to do it as cleanly and effectively as I currently know how. What i'm wanting to know is, is there somewhere I can submit this app, and have some seasoned developers provide feedback. It's not just a subsection of my code like 'codereview.stackexchange' appears to require, it's my entire workflow that I want critiqued. I know this is a lot to ask, and I expect the main advice given will be to look for a job within a team, which is certainly something I will look into later down the track, but for now I want to persist with my current employment situation, but just don't want to develop too many bad habits. Let me know if I can provide any further information to help clarify, or if this isn't the right place for this type of question I apologise in advance. Didn't want to use reddit as I felt this community fosters more well thought out responses.

• World Record Oracle E-Business Consolidated Workload on SPARC T4-2

  - by Brian

  Oracle set a World Record for the Oracle E-Business Suite Standard Medium multiple-online module benchmark using Oracle's SPARC T4-2 and SPARC T4-4 servers which ran the application and database. Oracle's SPARC T4 servers demonstrate performance leadership and world-record results on Oracle E-Business Suite Applications R12 OLTP benchmark by publishing the first result using multiple concurrent online application modules with Oracle Database 11g Release 2 running Solaris.   This results shows that a multi-tier configuration of SPARC T4 servers running the Oracle E-Business Suite R12.1.2 application and Oracle Database 11g Release 2 is capable of supporting 4,100 online users with outstanding response-times, executing a mix of complex transactions consolidating 4 Oracle E-Business modules (iProcurement, Order Management, Customer Service and HR Self-Service).   The SPARC T4-2 server in the application tier utilized about 65% and the SPARC T4-4 server in the database tier utilized about 30%, providing significant headroom for additional Oracle E-Business Suite R12.1.2 processing modules, more online users, and future growth.   Oracle E-Business Suite Applications were run in Oracle Solaris Containers on SPARC T4 servers and provides a consolidation platform for multiple E-Business instances.   Performance Landscape Multiple Online Modules (Self-Service, Order-Management, iProcurement, Customer-Service) Medium Configuration System Users AverageResponse Time 90th PercentileResponse Time SPARC T4-2 4,100 2.08 sec 2.52 sec Configuration Summary Application Tier Configuration: 1 x SPARC T4-2 server 2 x SPARC T4 processors, 2.85 GHz 256 GB memory 3 x 300 GB internal disks Oracle Solaris 10 Oracle E-Business Suite 12.1.2 Database Tier Configuration: 1 x SPARC T4-4 server 4 x SPARC T4 processors, 3.0 GHz 256 GB memory 2 x 300 GB internal disks Oracle Solaris 10 Oracle Solaris Containers Oracle Database 11g Release 2 Storage Configuration: 1 x Sun Storage F5100 Flash Array (80 x 24 GB flash modules) Benchmark Description The Oracle R12 E-Business Suite Standard Benchmark combines online transaction execution by simulated users with multiple online concurrent modules to model a typical scenario for a global enterprise.

• TDC: The Developer's Conference Day One

  - by Tori Wieldt

  The Developer's Conference (TDC) kicked off Wednesday in São Paulo, Brazil. With over 3000 developers in attendance over five days, it is the premier multi-community developer conference in Brazil, organized by Globalcode. Yara Senger, one of the organizers said, "We like to say multi-community rather than multi-technology because it is interesting and benefical when various communities get together. They learn so much from each other!" TDC includes tracks on Java and several other technologies, including SOA, Python, Ruby, mobile and digital TV. In the mobile track, developers who create a Java ME app will get a Nokia S40 phone!New this year at TDC is the Java University track, sponsored by Oracle.  It is aimed at university students and professionals who are new to Java. The lectures are introductory level, with an educational focus and practical exercises. The Java track and other tracks, such as SOA, mobile and Digital TV, are getting lots of help from the expertise of Brazilian JUGS members. Thanks to GoJava, JavaBahia, JavaNoroeste and SouJava!Carlos Fernando, one of the coordinators on the Digital TV track, said "My goal is to teach developers the basics of digital TV, and show them the tools used to build interactive TV applications." Fernando explained the concept of "the second screen:" that many people watch TV and have second smart device (tablet or smartphone) with them, and this creates many opportunities for developers. For example, while watching TV, a viewer can get extra content (interviews, behind the scenes) on their tablet. More interestingly, while watching their favorite TV show a viewer likes an outfit one of the actors is wearing, their smartphone can tell them where they can buy it nearby, or they can order it online immediately. Fernando exclaimed, "The opportunities for developers are nearly infinite in the area of digital TV!" At the TDC opening keynote, Debora Palermo, Oracle University country manager for Brazil, reminded attendees that Java is present in many devices, from simple to complex, and knowledge of this platform can open many doors in the labor market. She explained Oracle's Workforce Development Program (WDP), managed by Oracle University, which allows educational institutions to deliver Oracle training. WDP allows for easy and low-cost access to Oracle training in local communities across the world. "Oracle University is committed to creating the next generation of Java developers, and WDP can make that happen," Palermo said. As of March 2012, Oracle University is partnering with Globalcode to offer WDP. Students can earn official Oracle Course Certifications, a great way to learn Java.Brazilian developers that cannot attend TDC can watch live streaming.

• The JDEdwards EnterpriseOne PreSales University

  - by Julien Haye

  Istanbul NOV 5-9 Wednesday, NOV 7 - It is raining outside and I am sitting in my hotel room (#106) in Istanbul and create my first blog entry. Today this blog was enabled and I am excited to have the ability to share my (first) thoughts with the EMEA JDE Partner Community. I am here in Istanbul because we are currently running the JDEdwards PreSales University Event series. This PreSales University is an established event series which we deliver the fifth time now and the first time in the ECEMEA region. Delegates value the openness and competence from the Product Strategy and Product Development Team from Denver and India. Together with the regional Oracle PreSales team we had very valuable discussions around product features and functions and about the business value of the new delivered applications and tools. Additionally the event provides endless opportunities to exchange ideas with other JD Edwards Partner and the Oracle PreSales Team. With its focus on sharing and learning, best practice, user experience and transforming technologies, delegates will leave this event with an abundance of new ideas and best practices to try for your coming projects and existing customer implementations. A day out of the office gives delegates a chance to gain a new perspective on their business processes. Everybody sees better ways of working just by being immersed in an environment where the focus is on using products more effectively. Apps Track: Highly concentrated participants in Istanbul listening to Jeff Erickson presenting the news about OneView Reporting. Jeff: We believe “The things you said”. The event is organized into two tracks, one for Apps and one for Tech. Everybody was able to learn new features and functions and how to position this products. The focus was on the new Apps release 9.1 and Tools Release 9.1.2 and their Value Propositions. For all topics hands-on exercises has been given to the participants. Even very experienced senior consultants did learn a lot from this event. In total we have 55 people registered and we still have some more content to deliver. By the way: Istanbul is a nice place to be. I already booked my next trip to this beautiful city. In two weeks we deliver the JD Edwards EECIS Executive Forum again in Istanbul. Once again a tough Agenda. I will let you know if I had the ability to have a walk outside and see a bit more of this beautiful city. At least I expect to have a different room number. Many greetings Hartmut WieseOracle Alliances & Channels EMEA

• Restoring MSDB

  - by David-Betteridge

  We recently performed a disaster recovery exercise which included the restoration of the MSDB database onto our DR server.  I did a quick google to see if there were any special considerations and found the following MS article.  Considerations for Restoring the model and msdb Databases (http://msdn.microsoft.com/en-us/library/ms190749(v=sql.105).aspx).   It said both the original and replacement servers must be on the same version,  I double-checked and in my case they are both SQL Server 2008 R2 SP1 (10.50.2500).. So I went ahead and stopped SQL Server agent, restored the database and restarted the agent.  Checked the jobs and they were all there, everything looked great, and was until the server was rebooted a few days later.Then the syspolicy_purge_history job started failing on the 3rd step with the error message “Unable to start execution of step 3 (reason: The PowerShell subsystem failed to load [see the SQLAGENT.OUT file for details]; The job has been suspended). The step failed.”   A bit more googling pointed me to the msdb.dbo.syssubsystems table SELECT * FROM msdb.dbo.syssubsystems WHERE start_entry_point ='PowerShellStart'   And in particular the value for the subsystem_dll. It still had the path to the SQLPOWERSHELLSS.DLL but on the old server. The DR instance has a different name to the live instance and so the paths are different.   This was quickly fixed with the following SQL Use msdb; GO sp_configure 'allow updates', 1 ; RECONFIGURE WITH OVERRIDE ; GO UPDATE msdb.dbo.syssubsystems SET subsystem_dll='C:\Program Files\Microsoft SQL Server\MSSQL10_50.DR\MSSQL\binn\SQLPOWERSHELLSS.DLL' WHERE start_entry_point ='PowerShellStart'; GO sp_configure 'allow updates', 0; RECONFIGURE WITH OVERRIDE ; GO Stopped and started SQL Server agent and now the job completes.   I then wondered if anything else might be broken, SELECT subsystem_dll FROM msdb.dbo.syssubsystems Shows a further 10 wrong paths – fortunately for parts of SQL (replication, SSIS etc) we aren’t using! Lessons Learnt 1.       DR exercises are a good thing! 2.       Keep the Live and DR environments as similar as possible.

• Improving the performance of JDeveloper11g (part 2) and JVMs in general

  - by asantaga

  Just received an email from one of our JVM developers who read my blog entry on Performance tuning JDeveloper11g and he's confirmed that all of the above parameters are totally supported :-) He's also provided a description of the parameters so we can learn what magic is actually being applied. - -XX:+AggressiveOpts -- this enables the latest and greatest JVM optimizations. It will likely help most Java applications. It's fully supported. The downside of it is that because it has the latest and greatest optimizations, there is some small probability that it may not offer as good of an experience. As those features enabled with this command line option have "matured", they are made the default in a future JDK release. So, you can think of this command line option as the place where the newest optimizations get introduced. Some time later they are moved out from under AggressiveOpts to become default behavior. -XX:+OptimizeStringConcat -- only works with the -server JVM. It may be enabled by the default in a future JDK 7 update release. This option delays the construction of a StringBuilder/StringBuffer and attempts to avoid re-sizing the underlying char[] by attempting to detect the size of the char[] to allocate based on what's being appended to the StringBuilder/StringBuffer. -XX:+UseStringCache -- I would not suggest using this unless you knew that JDeveloper allocated the same string over and over again. And, the string that's allocated over and over again is one of the first 100,000 allocated strings. In short, I'd recommend against using it. And, in fact, in Java 7 (currently) does not include this feature. -XX:+UseCompressedOops -- applicable to 64-bit JVMs. And, if you're using a 64-bit JVM, I'd suggest you use it. It's auto enabled in JDK 7 64-bit JVMs and later JDK 6 64-bit JVMs enable it by default too. -XX:+UseGCOverheadLimit -- by default this option is already enabled. One other command line option to consider is -XX:+TieredCompilation for a JDK 6 Update 25 or later, or JDK 7. This gives you the startup of a -client JVM and the peak performance of a -server JVM. Awesome-ness!  Finally, Charlies also pointed out to me a "new" book he's just published where he goes into the details of JVM tuning, a must for all Fusion Middleware tuning exercises..  (click the book)  Thanks Charlie!

• ConsumeStructuredBuffer, what am I doing wrong?

  - by John

  I'm trying to implement the 3rd exercise in chapter 12 of Introduction to 3D Game Programming with DirectX 11, that is: Implement a Compute Shader to calculate the length of 64 vectors. Previous exercises ask you to do the same with typed buffers and regular structured buffers and I had no problems with them. For what I've read, [Consume|Append]StructuredBuffers are bound to the pipeline using UnorderedAccessViews (as long as they use the D3D11_BUFFER_UAV_FLAG_APPEND, and the buffers have both D3D11_BIND_SHADER_RESOURCE and D3D11_BIND_UNORDERED_ACCESS bind flags). Problem is: my AppendStructuredBuffer works, since I can append data to it and retrieve it from the application to write to a results file, but the ConsumeStructuredBuffer always returns zeroed data. Data is in the buffer, since if I change the UAV to a ShaderResourceView and to a StructuredBuffer in the HLSL side it works. I don't know what I am missing: Should I initialize the ConsumeStructuredBuffer on the GPU, or can I do it when I create the buffer (as I amb currently doing). Is it OK to bind the buffer with a UAV as described above? Do I need to bind it as a ShaderResourceView somehow? Maybe I am missing some step? This is the declaration of buffers in the Compute Shader: struct Data { float3 v; }; struct Result { float l; }; ConsumeStructuredBuffer<Data> gInput; AppendStructuredBuffer<Result> gOutput; And here the creation of the buffer and UAV for input data: D3D11_BUFFER_DESC inputDesc; inputDesc.Usage = D3D11_USAGE_DEFAULT; inputDesc.ByteWidth = sizeof(Data) * mNumElements; inputDesc.BindFlags = D3D11_BIND_SHADER_RESOURCE | D3D11_BIND_UNORDERED_ACCESS; inputDesc.CPUAccessFlags = 0; inputDesc.StructureByteStride = sizeof(Data); inputDesc.MiscFlags = D3D11_RESOURCE_MISC_BUFFER_STRUCTURED; D3D11_SUBRESOURCE_DATA vinitData; vinitData.pSysMem = &data[0]; HR(md3dDevice->CreateBuffer(&inputDesc, &vinitData, &mInputBuffer)); D3D11_UNORDERED_ACCESS_VIEW_DESC uavDesc; uavDesc.Format = DXGI_FORMAT_UNKNOWN; uavDesc.ViewDimension = D3D11_UAV_DIMENSION_BUFFER; uavDesc.Buffer.FirstElement = 0; uavDesc.Buffer.Flags = D3D11_BUFFER_UAV_FLAG_APPEND; uavDesc.Buffer.NumElements = mNumElements; md3dDevice->CreateUnorderedAccessView(mInputBuffer, &uavDesc, &mInputUAV); Initial data is an array of Data structs, which contain a XMFLOAT3 with random data. I bind the UAV to the shader using the Effects framework: ID3DX11EffectUnorderedAccessViewVariable* Input = mFX->GetVariableByName("gInput")->AsUnorderedAccessView(); Input->SetUnorderedAccessView(uav); // uav is mInputUAV Any ideas? Thank you.

• Insanity&ndash;Day 1

  - by D'Arcy Lussier

  Some people do those posts about “Here’s what I’m going to do to change my life”. I don’t really like those. I’m a “don’t tell me what you’re going to do, tell me what you’re doing/have done” type of guy. So while I could say how I’m going to change my life and be healthier and happier and thinner in 60 days, I’m just going to tell you how I’m progressing through the Insanity workout. Insanity is a workout-in-a-box. It’s a collection of DVDs that you work out to. Nothing new here, except that the program is intense. It’s core tenet of the program is intensity – you workout at an elevated heart rate for 3 minutes with a short break in between, as opposed to traditional interval training where you go hard for a short time and recover for a few minutes. The other aspect of it is commitment. There is a timetable to follow – you workout 6 days a week with one rest day. This isn’t meant to be a “pick it up whenever you feel like it” type of program. The videos themselves are kind of…I don’t want to say low quality, but not as polished as I expected. Maybe that’s what they were going for. By that I mean they show shots of cameramen and the production equipment during the workout. Otherwise, it’s the Insanity leader Shawn T. leading a group of pretty fit folks through this gruelling workout. And ultimately, those little production nit-picks are irrelevant compared to the actual workout. Holy crap. I haven’t done an aerobics class in like…ever. And watching the video before my actual workout, I thought “That doesn’t look too hard”. Believe me, it is. No weights, no machines, just various exercises done in circuits and with increasing speed. By the end of the workout, I was drenched. So that was day one. Some stats just so I can track it: I’m 286 lbs at my last weigh-in a week ago or so. Should be interesting to see what 60 days of this does! D

• Why does bash sometimes think my $HOME isn't the correct directory?

  - by Adam Yanalunas

  Like the title says it seems that bash sometimes misidentifies my $HOME. This cropped up after a seemingly unique series of events that I will now replay in broad strokes. Running OS X 10.6 with normal, local account Work binds my account to Active Directory Much time passes with no issues Set up rvm to manage Ruby installs (this becomes important later) Upgraded to OS X 10.7 a few days ago After successful install, attempted to log in, was presented with "Must reset password" dialog that never allowed a password to be reset. Would simply shake the box after new password was entered. Much googling was done. Much more googling was done. Swearing was had. Logged in as root, created new account, set as admin, deleted /Users/[new account], renamed /Users/[old account] to /Users/[new account] Logged out of root, logged into new account with no issues After OS X asking for a my account password a few times to update Keychain and other system-level stuff it was back to business as usual. Opened Terminal, cd to project folder, tried "rails server" and was presented with: /usr/local/lib/ruby/1.9.1/rubygems/dependency.rb:247:in to_specs': Could not find rails (>= 0) amongst [] (Gem::LoadError) from /usr/local/lib/ruby/1.9.1/rubygems/dependency.rb:256:into_spec' from /usr/local/lib/ruby/1.9.1/rubygems.rb:1210:in gem' from /usr/local/bin/rails:18:in' Ran through a few exercises, decided to rm -rf ~/.rvm and reinstall. Running a --trace on the rvm installer shows it dies on this line: mkdir: /Users/[old account]: Permission denied Scrolling back through the --trace log I see many more mentions of /Users/[old account]. When inspect the install script the offending line is looking at "${HOME}/.rvm" as it tries to run the mkdir. To my confusion I also see mentions of /Users/[new account] in the log. I've tried exporting a new HOME in my .bash_profile to no luck. Can anyone guess why /Users/[old account] would still be kicking around?

• NTDS Replication Warning (Event ID 2089)

  - by Chris_K

  I have a simple little network with 3 AD servers in 2 sites. Site A has Win2k3 SP2 and Win2k SP4 servers, site B has a single Win2k3 SP2 server. All have been in place for at least 3 years now. Just last week I started getting Event 2089 "not backed up" warnings (example below) on both of the win2k3 servers. I understand what the message means, no need to send me links to the technet article explaining it. I'll improve my backups. What I'm more curious about is why did I just start getting this message now? Why haven't I been getting it for the past 3 years?!? Perhaps this is related: I recently decommissioned a few other sites and AD controllers (there used to be 3 more sites, each with their own controller). Don't worry, I did proper DCpromo exercises and made sure we didn't lose anything. But would shutting those down possibly be related to why I get this error now? This won't keep me awake at night but I am curious as to what changed...

• Why did you start with Linux ? And why did you continue using it ?

  - by Stefano Borini

  I'd like to know the reasons that moved you towards Linux. Personally, I started because we had to use a Digital for the Fortran 77 exercises during my first year at the university. Linux was installed on many university computers, and I got interested in it. I always liked to code (on the C64) in basic and assembler, but I knew nothing about other languages. I soon discovered a chat engine called NUTS, and the idea of becoming proficient in C appealed me, so I started hacking the code. To do so, I needed a Unix at home, so I bought a Slackware 3.4 and installed it on my Pentium 166. I then continued using it for many years, reason being that I had pleasure in learning new things and the openness of information about the internals. It was a great learning platform. I then moved to osx because I enjoy the power of Unix with the beauty and efficiency of its interface. I am interested in your answer because I believe that the panorama has changed somehow. Although I still guess to find many "hackers" interested in Linux for the sake of knowledge, I also believe that there are other reasons (work, friends, bought a netbook).

The SPECjEnterprise2010 benchmark has been designed and developed to cover the Java EE 5 specification's significantly expanded and simplified programming model, highlighting the major features used by developers in the industry today. This provides a real world workload driving the Application Server's implementation of the Java EE specification to its maximum potential and allowing maximum stressing of the underlying hardware and software systems. The workload consists of an end to end web based order processing domain, an RMI and Web Services driven manufacturing domain and a supply chain model utilizing document based Web Services. The application is a collection of Java classes, Java Servlets, Java Server Pages, Enterprise Java Beans, Java Persistence Entities (pojo's) and Message Driven Beans. The SPECjEnterprise2010 benchmark heavily exercises all parts of the underlying infrastructure that make up the application environment, including hardware, JVM software, database software, JDBC drivers, and the system network. The primary metric of the SPECjEnterprise2010 benchmark is jEnterprise Operations Per Second ("SPECjEnterprise2010 EjOPS"). This metric is calculated by adding the metrics of the Dealership Management Application in the Dealer Domain and the Manufacturing Application in the Manufacturing Domain. There is no price/performance metric in this benchmark. Key Points and Best Practices Sixteen Oracle WebLogic server instances were started using numactl, binding 2 instances per chip. Eight Oracle database listener processes were started, binding 2 instances per chip using taskset. Additional tuning information is in the report at http://spec.org.

• Welcome 2011

  - by PSteele

  About this time last year, I wrote a blog post about how January of 2010 was almost over and I hadn’t done a single blog post.  Ugh…  History repeats itself. 2010 in Review If I look back at 2010, it was a great year in terms of technology and development: Visited Redmond to attend the MVP Summit in February.  Had a great time with the MS product teams and got to connect with some really smart people. Continued my work on Visual Studio Magazine’s “C# Corner” column.  About mid-year, the column changed from an every-other-month print column to an every-other-month print column along with bi-monthly web-only articles.  Needless to say, this kept me even busier and away from my blog. Participated in another GiveCamp!  Thanks to the wonderful leadership of Michael Eaton and all of his minions, GiveCamp 2010 was another great success.  Planning for GiveCamp 2011 will be starting soon… I switched to DVCS full time.  After years of being a loyal SVN user, I got bit by the DVCS bug.  I played around with both Mercurial and Git and finally settled on Mercurial.  It’s seamless integration with Windows Explorer along with it’s wealth of plugins made me fall in love.  I can’t imagine going back and using a centralized version control system. Continued to work with the awesome group of talent at SRT Solutions.  Very proud that SRT won it’s third consecutive FastTrack award! Jumped off the BlackBerry train and enjoying the smooth ride of Android.  It was time to replace the old BlackBerry Storm so I did some research and settled on the Motorola DroidX.  I couldn’t be happier.  Android is a slick OS and the DroidX is a sweet piece of hardware.  Been dabbling in some Android development with both Eclipse and IntelliJ IDEA (I like IntelliJ IDEA a lot better!).   2011 Plans On January 1st I was pleasantly surprised to get an email from the Microsoft MVP program letting me know that I had received the MVP award again for my community work in 2010.  I’m honored and humbled to be recognized by Microsoft as well as my peers! I’ll continue to do some Android development.  I’m currently working on a simple app to get me feet wet.  It may even makes it’s way into the Android Market. I’ve got a project that could really benefit from WPF so I’ll be diving into WPF this year.  I’ve played around with WPF a bit in the past – simple demos and learning exercises – but this will give me a chance to build an entire application in WPF.  I’m looking forward to the increased freedom that a WPF UI should give me. I plan on blogging a lot more in 2011! Technorati Tags: Android,MVP,Mercurial,WPF,SRT,GiveCamp

• SQL Authority News – Presenting at SQL Bangalore on May 3, 2014 – Performing an Effective Presentation

  - by Pinal Dave

  SQL Bangalore is a wonderful community and we always have a great response when we present on technology. It is SQL User Group and we discuss everything SQL there. This month we have SQL Server 2014 theme and we are going to have a community launch on this subject. We have the best of the best speakers presenting on SQL Server 2014 technology. Looking at the whole line of celebrity speakers, I have decided not to present on SQL Server. I will be presenting on the performance tuning subject, but with the twist of soft skills. I will be presenting on “Performing an Effective Presentation“. Trust me, you do not want to miss this presentation, I will be presenting on how to present effectively when presenting SQL Server topics. What this session will NOT have I personally believe that we all are good presenters most of the time. We can all easily call out if someone is bad presenter. There is no point talking about basics like bigger bullet points, talk loudly, talk with confidence, use better analogies etc. In simple words – this is not going to some philosophy session and boring notes. What this session will have Well, this session will tell stories of my life. It will tell how we can present about technology and SQL Server with the help of stories and personal experience. I am going to tell stories about two legends  who have inspired me. Right after that we will be doing two exercises together where we will learn quickly and effectively, how to become better speaker – instantly! There is no video recording of this session. If you want to get resources from this session, please sign up my newsletter at http://bit.ly/sqllearn Here are few of the slides from this presentation: Here is the details about the event and location Venue:Microsoft Corporation, Signature Building,Embassy Golf Links Business Park, Intermediate Ring Road, Domlur, Bangalore – 560071 The agenda is amazing – we have top line SQL Speakers. Everyone is welcome and don’t forget to get your friend along for this event. Loads to learn and tons to share !!! Keynote (20 mins) by Anupam Tiwari – Business Program Manager – GTSC Backup Enhancements with SQL Server 2014 by Amit Banerjee – PFE Microsoft Performance Enhancements with SQL Server 2014 by Sourabh Agarwal - PFE Microsoft LUNCH BREAK Performing an effective Presentation by Pinal Dave – Community Member (SQLAuthority.com) InMemory Enhancements with SQL Server 2014 by Balmukund Lakhani – Support Escalation Engg.

Microsoft I am very big fan of Amit, Balmukund and Vinod – I have always watched their session and this time, I am going to once again attend their session without missing a single min.

• Book Review (Book 12) - 20 Master Plots

  - by BuckWoody

  This is a continuation of the books I challenged myself to read to help my career - one a month, for a year. You can read my first book review here, and the entire list is here. The book I chose for May 2012 was:20 Master Plots by Ronald B. Tobias. This is my final book review - at least for this year. I'll explain what I've learned in this book in particular, and in the last twelve months in general. Why I chose this book: Stories and themes are part of software, presenting, and working in teams. This book claims there are only 20 plots, ever. I wanted to find out. What I learned: Probably my most favorite read of the year. Deceptively small, amazingly insightful. The premise is that there are only a few "base" themes, and that once you learn them you can put together an interesting set of stories on most any topic. Yes, the author admits that this number has been different throughout history - some have said 50, others 14, and still others claim only one or two basic plots. This doesn't change the fact that you can build very complex stories from a simple set of circumstances and characters. Be warned - if you read this book it takes away much of the wonder from almost every movie or book you'll read from here on! I loved it. My favorite part is that the author gives you exercises to build stories, right from the start. I've actually used these as the start of a meeting to foster creativity. Amazing stuff. One of my favorite sections of the book deals with plot and story. Plot: The king died, and the queen died. Story: The king died, and the queen died of heartbreak. Add one or two words, and you have the essence of storytelling. A highly recommended read, for all folks of all ages. You'll like it, your spouse will like it, and your kids will like it. I learned to be a better storyteller, and it helped me understand that plots and stories are not just things in books - they are a direct reflection of human nature. That makes me a better manager of myself and others.   And this is the last of the reviews - at least for this year. I probably won't post many more book reviews here, but I will keep up the practice. As a reminder, the goal was to select 12 books that will help you reach your career goals. They don't have to be technical, or even apply directly to your job - but they do need to be books that you mindfully select as getting you closer to what you want to be. Each month, jot down what you learned from the work. And see if it doesn't in fact get you closer to your goals. These readings helped me - I got a promotion this year, and I attribute at least some of that to the things I learned.

• Calculating for leap year [migrated]

  - by Bradley Bauer

  I've written this program using Java in Eclipse. I was able to utilize a formula I found that I explained in the commented out section. Using the for loop I can iterate through each month of the year, which I feel good about in that code, it seems clean and smooth to me. Maybe I could give the variables full names to make everything more readable but I'm just using the formula in its basic essence :) Well my problem is it doesn't calculate correctly for years like 2008... Leap Years. I know that if (year % 400 == 0 || (year % 4 == 0 && year % 100 != 0)) then we have a leap year. Maybe if the year is a leap year I need to subtract a certain amount of days from a certain month. Any solutions, or some direction would be great thanks :) package exercises; public class E28 { /* * Display the first days of each month * Enter the year * Enter first day of the year * * h = (q + (26 * (m + 1)) / 10 + k + k/4 + j/4 + 5j) % 7 * * h is the day of the week (0: Saturday, 1: Sunday ......) * q is the day of the month * m is the month (3: March 4: April....

• Questions to ask to ensure someone understands programming? (and iOS)

  - by Stephen J

  So, I've been tutoring my friend for 2 years. Most people learn programming on their own in 3-6 months, (sans algorithms). It's confusing 'cause he'll run anywhere I tell him to, understands how to read C and C++ honestly better than the average college student, and he'll modify and repeat anything I do... but for the love of god he doesn't move on to new things and he still has test anxiety. I've recently realized he's copied and toyed with existing, but not once gained an understanding of why. I was under the impression he was learning fast because he could write it, but when you say "Make a function that takes an NSString" and he says "How?" and I say "The same way you make ANY function that takes any parameter, NSString is just a type like int" and all I hear is "No, it's an NSString, it's a special thing." and we get into an arguing match 'cause I'm like "It's just a class like any other class, you've used them for months now" and blah... I've subconsciously avoided comprehension questions because of this. Anyway, if you have him copy a program and say "Just initialize it" "Where?" "I don't care, didLoad or initWithCoder or Awake from nib, anywhere it gets initialized" and "No, it has to be exactly where you had it!" "No it doesn't!" I'm sick of this, but he won't give up. So I'm done avoiding these yelling matches and becoming a sadist from now on. I would like some help in finding questions to ask him that force him to understand what he's doing. I'd like some help and any resources I can find. CQuestions looked like a good site, but now I need some iPhone stuff. For example: *What do properties do? How are they changed? How do you change the name of the getter? *Why are Booleans inefficent? What advantage does int have over a boolean and how does the bit-shift operator help? *What does Copy do to a string? *What's the difference between a view controller and a uiview? *Write a program from memory that displays blah on screen, and flashes each view one by one. From beginner up to intermediate, hobbyist with some algebra at most. I'm just looking for resources to work with. I left in backstory so you know to "twist" the questions so he doesn't know he's supposed to init a variable here or there, but has to figure it out, and learn why it goes "here" or that "anywhere is fine as long as it's". Sample programs, anything. I'm relatively open about this because, being a programmer, I seriously doubt he's the only one who has this issue. I'd like to know how others have overcome similar. What made things "click"? for you? Did you have a hard time finding answers on Google, and how did you learn a better way to find what you were looking for? (He's so exact, he'll search for how to write a checkers program with color X and Y inside a uiview, as his search string, instead of breaking it up into components, I need help with that too, and believe it is related). This type of problem has to remind one of us of someone they know. So, Exercises to force them to think? Ways we overcame this thing in the past? I greatly appreciate any help.

• How to pass a parameter to jQuery UI dialog event handler?

  - by bebraw

  I am currently trying to hook up jQuery UI dialog so that I may use it to create new items to my page and to modify ones existing already on the page. I managed in the former. I'm currently struggling in the latter problem, however. I just cannot find a nice way to pass the item to modify to the dialog. Here's some code to illustrate the issue better. Note especially the part marked with XXX. The {{}} parts are derived from Django template syntax: $(".exercise").click(function() { $.post("{{ request.path }}", { action: "create_dialog", exercise_name: $(this).text() }, function(data) { $("#modify_exercise").html(data.content); }, "json" ); $("#modify_exercise").dialog('open'); }); $("#modify_exercise").dialog({ autoOpen: false, resizable: false, modal: true, buttons: { '{% trans 'Modify' %}': function() { var $inputs = $('#modify_exercise :input'); var post_values = {}; $inputs.each(function() { post_values[this.name] = $(this).val(); }); post_values.action = 'validate_form'; //XXX: how to get the exercise name here? post_values.exercise_name = 'foobar'; $.post('{{ request.path }}', post_values, function(data) { if( data.status == 'invalid' ) { $('#modify_exercise').html(data.content); } else { location.reload(); } }, "json" ); } } }); Here's some markup to show how the code relates to the structure: <div id="modify_exercise" class="dialog" title="{% trans 'Modify exercise' %}"> </div> <ul> {% for exercise in exercises %} <li> <a class="exercise" href="#" title="{{ exercise.description }}"> {{ exercise.name }} </a> </li> {% endfor %} </ul>
