  • How to dealing with the "programming blowhard"?

    - by Peter G.
    (Repost, I posted this in the wrong section before, sorry) So I'm sure everyone has run into this person at one point or another, someone catches wind of your project or idea and initially shows some interest. You get to talking about some of your methods and usually around this time they interject stating how you should use method X instead, or just use library Y. But not as a friendly suggestion, but bordering on a commandment. Often repeating the same advice over and over like a overzealous parrot. Personally, I like to reinvent the wheel when I'm learning, or even just for fun, even if it turns out worse than what's been done before. But this person apparently cannot fathom recreating ANY utility for such purposes, or possibly try something that doesn't strictly follow traditional OOP practices, and will settle for nothing except their sense of perfection, and thus naturally heave their criticism sludge down my ears full force. To top it off, they eventually start justifying their advice (retardation) by listing all the incredibly complex things they've coded single-handedly (usually along the lines of "trust me, I've made/used program X for a long time, blah blah blah"). Now, I'm far from being a programming master, I'm probably not even that good, and as such I value advice and critique, but I think advice/critique has a time and place. There is also a big difference between being helpful and being narcissistic. In the past I probably would have used a somewhat stronger George Carlin style dismissal, but I don't think burning bridges is the best approach anymore. Maybe I'm just an asshole, but do you have any advice on how to deal with this kind of verbal flogging?

  • Install both 64-bit and 32-bit JDK on a 64-bit windows?

    - by Toperi
    I need to use a java library that uses native code requiring a 32-bit jvm. I have 64-bit windows with 64-bit eclipse installed with 64-bit JDK7. In order to develop with it, do I need to have 32-bit JDK? Or would the JRE suffice? If it is possible to install both, what is the naming convention you use for the installation directory for the 32-bit jre or jdk? I have heard rumors there is a performance hit on virtual memory if both are installed, is this true?

  • Performance issue when configuring non HA VM in cluster

    - by laiys
    Hi, I saw this article http://technet.microsoft.com/en-us/library/cc764243.aspx Quote taken from the link “ Important It is recommended that you not deploy virtual machines that are not highly available on your host clusters. Although you can do this by using Hyper-V (VMM does not allow it), the non-highly available virtual machines will consume resources that otherwise would be available to the HAVMs What kind of resources (CPU,memory, NIC, etc) that non HA VM will consume? Just curious as not all VM (in production) not to be in Failover Cluster and Live Migration. If i put the VM into CSV but did not make it as HA, what impact does it make since i allocate same vCPU, vNic and VMemory into the VM. (not to mention that i lost failover feature). Curious to understand more about this. Please advise. Thanks

  • Creating PDF Documents with ASP.NET and iTextSharp

    The Portable Document Format (PDF) is a popular file format for documents. Due to their ubiquity and layout capabilities, it's not uncommon for a websites to use PDF technology. For example, an eCommerce store may offer a "printable receipt" option that, when selected, displays a PDF file within the browser. Last week's article, Filling in PDF Forms with ASP.NET and iTextSharp, looked at how to work with a special kind of PDF document, namely one that has one or more fields defined. A PDF document can contain various types of user interface elements, which are referred to as fields. For instance, there is a text field, a checkbox field, a combobox field, and more. Typically, the person viewing the PDF on her computer interacts with the document's fields; however, it is possible to enumerate and fill a PDF's fields programmatically, as we saw in last week's article. This article continues our investigation into iTextSharp, a .NET open source library for PDF generation, showing how to use iTextSharp to create PDF documents from scratch. We start with an example of how to programmatically define and piece together paragraphs, tables, and images into a single PDF file. Following that, we explore how to use iTextSharp's built-in capabilities to convert HTML into PDF. Read on to learn more! Read More >

  • Step by Step screencasts to do Behavior Driven Development on WCF and UI using xUnit

    - by oazabir
    I am trying to encourage my team to get into Behavior Driven Development (BDD). So, I made two quick video tutorials to show how BDD can be done from early requirement collection stage to late integration tests. It explains breaking user stories into behaviors, and then developers and test engineers taking the behavior specs and writing a WCF service and unit test for it, in parallel, and then eventually integrating the WCF service and doing the integration tests. It introduces how mocking is done using the Moq library. Moreover, it shows a way how you can write test once and do both unit and integration tests at the flip of a config setting. Watch the screencast here: Doing BDD with xUnit, Subspec and on a WCF Service  Warning: you might hear some noise in the audio in some places. Something wrong with audio bit rate. I suggest you let the video download for a while and then play it. If you still get noise, go back couple of seconds earlier and then resume play. It eliminates the noise.  The next video tutorial is about doing BDD to do automated UI tests. It shows how test engineers can take behaviors and then write tests that tests a prototype UI in isolation (just like Service Contract) in order to ensure the prototype conforms to the expected behaviors, while developers can write the real code and build the real product in parallel. When the real stuff is done, the same test can test the real stuff and ensure the agreed behaviors are satisfied. I have used WatiN to automate UI and test UI for expected behaviors. Doing BDD with xUnit and WatiN on a ASP.NET webform Hope you like it!

  • 2D soft-body physics engines?

    - by Griffin
    Hi so i've recently learned the SFML graphics library and would like to use or make a non-rigid body 2D physics system to use with it. I have three questions: The definition of rigid body in Box2d is A chunk of matter that is so strong that the distance between any two bits of matter on the chunk is completely constant. And this is exactly what i don't want as i would like to make elastic, deformable, breakable, and re-connection bodies. 1. Are there any simple 2D physics engines, but with these kinds of characteristics out there? preferably free or opensource? 2. If not could i use box2d and work off of it to create it even if it's based on rigid bodies? 3. Finally, if there is a simple physics engine like this, should i go through with the proccess of creating a new one anyway, simply for experience and to enhance physics math knowledge? I feel like it would help if i ever wanted to modify the code of an existing engine, or create a game with really unique physics. Thanks!

  • With Monit, how do I restart a process when a directory timestamp check fails?

    - by Alterscape
    In my /etc/monit/monitrc I have the following lines: check process foo_server with pidfile /var/run/bwam_server.pid start program = "/Users/foo/foo_server.sh start" stop program = "/Users/foo/foo_server.sh stop" check directory foo_data path "/Users/foo/Library/Application Support/foo_server/data" if timestamp > 1 minute then alert #if timestamp > 1 minute then restart foo_server I know I shouldn't have some of this stuff in my home directory, but this aside: if I uncomment the last line, Monit tells me syntax error on foo_server -- but I am, as far as I understand, correctly defining the process -- how else do I reference it?

  • Music player alternative to windows Media Player

    - by patjbs
    I find the UI and general usability of the prepackaged windows Media Player to be cludgy and at times incomprehensible. I used to use programs like WinAmp and Sonique, many years ago. What are some current alternatives to the windows Media Player? I don't have iTunes - I'm pretty happy with ripping my own audio files from my album collection. I'm specifically looking for the follow qualities/abilities: Easy sorting and manipulation of the media library Easy tagging of media - marking favorites and ratings, etc. Preferably lightweight. Something like a Picasa for audio media.

  • Compiling zip component for PHP 5.2.11 in MAMP PRO

    - by Zlatoroh
    Helo I installed MAMP PRO on my Macbook Pro (10.6) some time ago. Now I would like to use zip functions in php. I found that I must add zip.so to my extension folder and edited php.ini. On my computer I have two different versions of PHP one in MAMP folder and other in user/lib which was pre-installed on my system. Now I wish to compile my zip library for MAMP version. I got zip sources for my version of PHP then in terminal called function /Applications/MAMP/bin/php5/bin/phpize so it uses mamp php version ./configure make then I moved compile zip.so to extensions/no-debug-non-zts-20060613. When MAMP is launched it returns this error: [11-Apr-2010 16:33:27] PHP Warning: PHP Startup: zip: Unable to initialize module Module compiled with module API=20090626, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=0 These options need to match in Unknown on line 0 Can some body explain to me how to do this the right way.

  • July, the 31 Days of SQL Server DMO’s – Day 28 (sys.dm_db_stats_properties)

    - by Tamarick Hill
    The sys.dm_db_stats_properties Dynamic Management Function returns information about the statistics that are currently on your database objects. This function takes two parameters, an object_id and a stats_id. Let’s have a look at the result set from this function against the AdventureWorks2012.Sales.SalesOrderHeader table. To obtain the object_id and stats_id I will use a CROSS APPLY with the sys.stats system table. SELECT sp.* FROM sys.stats s CROSS APPLY sys.dm_db_stats_properties(s.object_id, s.Stats_id) sp WHERE sp.object_id = object_id('Sales.SalesOrderHeader') The first two columns returned by this function are the object_id and the stats_id columns. The next column, ‘last_updated’, gives you the date and the time that a particular statistic was last updated. The next column, ‘rows’, gives you the total number of rows in the table as of the last statistic update date. The ‘rows_sampled’ column gives you the number of rows that were sampled to create the statistic. The ‘steps’ column represents the number of specific value ranges from the statistic histogram. The ‘unfiltered_rows’ column represents the number of rows before any filters are applied. If a particular statistic is not filtered, the ‘unfiltered_rows’ column will always equal the ‘rows’ column. Lastly we have the ‘modification_counter’ column which represents the number of modification to the leading column in a given statistic since the last time the statistic was updated. Probably the most important column from this Dynamic Management Function is the ‘last_updated’ column. You want to always ensure that you have accurate and updated statistics on your database objects. Accurate statistics are vital for the query optimizer to generate efficient and reliable query execution plans. Without accurate and updated statistics, the performance of your SQL Server would likely suffer. For more information about this Dynamic Management Function, please see the below Books Online link: http://msdn.microsoft.com/en-us/library/jj553546.aspx Folllow me on Twitter @PrimeTimeDBA

  • XNA extending the existing Content type

    - by Maarten
    We are doing a game in XNA that reacts to music. We need to do some offline processing of the music data and therefore we need a custom type containing the Song and some additional data: // Project AudioGameLibrary namespace AudioGameLibrary { public class GameTrack { public Song Song; public string Extra; } } We've added a Content Pipeline extension: // Project GameTrackProcessor namespace GameTrackProcessor { [ContentSerializerRuntimeType("AudioGameLibrary.GameTrack, AudioGameLibrary")] public class GameTrackContent { public SongContent SongContent; public string Extra; } [ContentProcessor(DisplayName = "GameTrack Processor")] public class GameTrackProcessor : ContentProcessor<AudioContent, GameTrackContent> { public GameTrackProcessor(){} public override GameTrackContent Process(AudioContent input, ContentProcessorContext context) { return new GameTrackContent() { SongContent = new SongProcessor().Process(input, context), Extra = "Some extra data" // Here we can do our processing on 'input' }; } } } Both the Library and the Pipeline extension are added to the Game Solution and references are also added. When trying to use this extension to load "gametrack.mp3" we run into problems however: // Project AudioGame protected override void LoadContent() { AudioGameLibrary.GameTrack gameTrack = Content.Load<AudioGameLibrary.GameTrack>("gametrack"); MediaPlayer.Play(gameTrack.Song); } The error message: Error loading "gametrack". File contains Microsoft.Xna.Framework.Media.Song but trying to load as AudioGameLibrary.GameTrack. AudioGame contains references to both AudioGameLibrary and GameTrackProcessor. Are we maybe missing other references?

  • I Could Sure Use Some Windows Azure Code Samples…

    - by BuckWoody
    There are multiple ways to learn, and one of the most effective is with examples. You have multiple options with Windows Azure, including the Software Development Kit, the Windows Azure Training Kit and now another one…. the Microsoft All-In-One Code Framework,, a free, centralized code sample library driven by developers' real-world pains and needs. The goal is to provide customer-driven code samples for all Microsoft development technologies, and Windows Azure is included. Once you hit the site, you download an EXE that will create a web-app based installer for a Code Browser.   Once inside, you can configure where the samples store data and other settings, and then search for what you want.   You can also request a sample – if enough people ask, we do it. OneCode also partnered with gallery and Visual Studio team to develop this Sample Browser Visual Studio extension.  It’s an easy way for developers to find and download samples from within Visual Studio.

  • Proper use of disk to disk to tape backup using de-duplication and LTO5

    - by Michael
    I currently have ~12TB of data for a full disk to tape (LTO3) backup. Needless to say, it's now requiring over 16 tapes so I'm looking at other solutions. Here is what I've come up with. I'd like to hear the community's thoughts. Server for Disk-to-Disk BackupExec 2010 Using De-duplication Technology 20+TB worth of SATA drives LTO5 robotic library connected via SAS 1Gbps NIC connected to network What I envision is doing a full backup of my entire network which will initially take a long time over the 1Gbps NIC but once the de-duplication kicks in backups should be quick. I will then use the LTO5 to make disk to tape backups and archive those accordingly. What does everyone think? Any faster way of doing the initial full backup over the 1Gbps NIC? What will be my pain points? Is there a better way of doing what I'm trying to achieve?

  • Munq is for web, Unity is for Enterprise

    - by oazabir
    The Unity Application Block (Unity) is a lightweight extensible dependency injection container with support for constructor, property, and method call injection. It’s a great library for facilitating Inversion of Control and the recent version supports AOP as well. However, when it comes to performance, it’s CPU hungry. In fact it’s so CPU hungry that it makes it impossible to make it work at Internet Scale. I was investigating some CPU issue on a portal that gets around 3MM hits per day and I found unusually high CPU. Here’s why: I did some CPU profiling on my open source project Dropthings and found that the highest CPU is consumed by Unity’s Resolve<>(). There’s no funky use of Unity in the project. Straightforward Register<>() and Resolve<>(). But as you can see, Resolve<>() is consuming significantly high CPU even after the site is warm and has been running for a while. Then I tried Munq, which is a basic Dependency Injection Container. It has everything you will usually need in a regular project. It boasts to be the fastest DI out there. So, I converted all Unity code to Munq in Dropthings and did a CPU profile and Whala!   There’s no trace of any Munq calls anywhere. That proves Munq is a lot faster than Unity.

GlassFish Extension for Oracle JDeveloper by Shay Shmeltzer We just release a new version of Oracle JDeveloper - 11.1.2.3. One new feature here is built-in support for GlassFish. This include the ability to create an "application server" connection to GlassFish and then deploy to that server with one click from inside JDeveloper. You can use this for deploying Oracle ADF Essentials application on Glassfish, but you can also use it to deploy any Java EE application you build in JDeveloper on GlassFish. However, if you are planning to work with GlassFish and JDeveloper on a more regular basis as your development server, then you might find my new extension useful. The new extension allows you to start and stop an external GlassFish instance, as well as start it in debug mode (which will allow JDeveloper to remotely debug your application as it runs on the server. I also added a button that will invoke the web admin console of Glassfish. Here is a quick demo that will show you how to work with the extension.

  • SharePoint 2010 Data Retrival Techinques

    - by Jayant Sharma
    In SharePoint, we have two options to perform CRUD operation.1. using server side code2. using client side codeusing server side code, we have 1. CAML2. LINQusing client side code, we have 1. Client Object Model    1.1.      Managed Client Object Model     1.2.     Silverlight Client Object Model    1.3.     ECMA Client Object Model2. SharePoint Web Services3. ADO Data Service (based on REST Web Services)4. Using RPC Call (owssvr.dll)Which and when these options are used depend upon requirements. Every options are certain advantages and disadvantages. So, before start development of any new sharepoint project, it is important to understand the limitations of different methods.Server Object Model is used when our application is host on the same server on which sharepoint is installed. while Client Side code is used to access sharepoint from client system. In SharePoint 2010 specially Client Object Model (COM) are introduced to perform the sharepoint operations from client system. Advantage of CAML:    -  It is fast.    -  Can be use it from all kind of technology like Silverlight, or Jquery    -  You can use U2U CAML Query builder to generate CAML Query.Disadvantage Of CAML:    - Error Prone, as we can detect the error only at runtimeAdvantage of LINQ:    -  Object Oriented technique (Object Relation Model)    -  LINQ  to SharePoint provider are working with Strongly Type List Item Objects, So intellisence are present at runtime    -  No need of knowledge of CAML    -  Less Error Prone as it as it uses C# syntex.    -  You can compare two Fields of SharePoint ListDisadvantage Of LINQ:    -  List Attachment is not supported in SPMetal Tool    -  Created By, Created, Modified and Modified By Fields are not created by SPMetal Tool.    -  Custom fields are not created by SPMetal Tools    -  External Lists are not supported    -  Though at backend LINQ genenates CAML Query so it is slower than directly using CAML in Code.  Advantage of Client Object Model    -  Used to access sharepoint from client system    -  No WebServer is required at Client End    - Can use Silverlight and JavaScripts to make better and fast User experienceDisadvantage of Client Object Model    -  You cannot use RunwithEleveatedPrivilege    - Cross Site Collection query are not possible    - Lesser API's are availableADO.Net Data Services:    -  Only List based operations are possible, other type of operations are not possible.SharePoint Web Services and RPC Call:    - Previously it was used in SharePoint 2007 but after the introduction  of Client Object Model,  Microsoft recommends not to use Web Services to fetch data from SharePoint. In SharePoint 2010 it is avaliable only for backward compatibility.Ref: http://msdn.microsoft.com/en-us/library/ee539764Jayant Sharma

    - by Eduard Florinescu
    Continuing from my previous question: Javascript simple code to understand prototype-based OOP basics Let's say we run into console this two separate objects(even if they are called child and parent there is no inheritance between them): var parent = { name: "parent", print: function(){ console.log("Hello, "+this.name); } }; var child = { name: "child", print: function(){ console.log("Hi, "+this.name); } }; parent.print() // This will print: Hello, parent child.print() // This will print: Hi, child temp =parent; parent = child; child = temp; parent.print() // This will now print: Hi, child child.print() // This will now print: Hello, parent Now suppose that parent is a library, as a HTML5 application in a browser this cannot do much harm because is practically running sandboxed, but now with the advent of the ChromeOS, FirefoxOS and other [Browser] OS they will also be linked to a native API, that would be a head out of the „sandbox”. Now if someone changes the namespace it would be harder for a code reviewer (either automated or not ) to spot an incorrect use if the namespaces changes. My question would be: Are there many ways in which the above situation can be done and what can be done to protect this namespaces? (Either in the javascript itself or by some static code analysis tool)

  • Where to set Visual studio 2013 property macros

    - by marcp
    I'm a new VS user. I've received some sample C++ projects working with a 3rd party API. They were saved in VS2012 format, but I have VS 2013. After conversion I find that there is an API specific macro defined in the project properties in the "Linker|General|Additional Library Directories" category. If I click on 'edit' I can replace the macro with an actual path, but how do I establish what the macro points to? In other words, how does one create a macro usable in multiple projects?

  • Be Careful When Referencing SPList.Items

    - by Brian Jackett
    Be very careful how you reference your SPListItem objects through the SharePoint API.  I’ll say it again.  Be very careful how you reference your SPListItem objects through the SharePoint API.  Ok, now that you get the point that this will be a “learn from my mistakes and don’t do unsmart things like I did” post, let’s dig into what it was that I did poorly. Scenario     For the past year I’ve been building custom .Net applications that are hosted through SharePoint.  These application involve a number of SharePoint lists, external databases, custom web parts, and other SharePoint elements to provide functionality.  About two weeks ago I received a message from one of our end users that a custom application was performing slowly.  Specifically performance was slow when users were performing actions that interacted with the primary SharePoint list storing data for that app. The Problem     I took a copy of the production site into a dev environment to investigate the code that was executing.  After attaching the debugger and running through the code I quickly found pieces of code referencing SPListItem objects (like below) that were performing very poorly: SPListItem myItem = SPContext.Current.Web.Lists["List Name"].Items.GetItemById(value); // do updates on SPListItem retrieved     As it turns out the SPList I was referencing was fairly large at ~1000 items and weighing in over 150 MB.  You see the problem with my above code is that I retrieved the SPListItem by first (unnecessarily) going through the Items member of the list.  As I understand it, when doing so the executing code will attempt to resolve that entity and pull it from the database and into RAM (all 150 MB.)  This causes the equivalent of a 50 car pile up in terms of performance with a single update taking more than 15 seconds. The Solution     The solution is actually quite simple and I wish I had realized this during development.  Instead of going through the Items member it is possible to call GetItemById(…) directly on the SPList as in the example below: SPListItem myItem = SPContext.Current.Web.Lists["List Name"].GetItemById(value); // do updates on SPListItem retrieved     After making this simple change performance skyrocketed and updates were back to less than a second.   Conclusion     When given the option between two solutions, usually the simplest is the best solution.  In my scenario I was adding extra complexity going through the API the long way around to get to the objects I needed and it ended up hurting performance greatly.  Luckily we were able to find and resolve the performance issue in a relatively short amount of time.  Like I said at the beginning of the post, learn from my mistakes and hope it helps you.         -Frog Out   Image linked from http://www.freespirit.com/files/IMAGE/COVER/LARGE/BeCarefulSafe.jpg
