  • What is the possible disadvantage of putting declarations in inner blocks, instead of at beginning of function?

    - by shan23
    At the place where I work, there are explicit guidelines for placement of declarations of variables. According to that, it is required to put them at the global level and / or at the beginning of functions, and not in inner blocks (such as a for loop). Since they've been specified by persons more experienced than I am, I'm sure that there must be a good reason for it, but I cannot figure out what that might be. It would be nice to know if there are any compile time / run time advantages at having them declared at a bigger scope.

  • What should I know before starting my first consulting project?

    - by bo4sho
    I just got a job for a small project. I have all the relevant skills and knowledge to complete the project, but I am concerned about getting screwed over because this is my first time working on a consultant basis. We have already agreed on an hourly wage that I'm happy with, so that's not an issue. I'm just worried that since this is my first time working on my own, I'm going to make some mistakes that could be easily avoided if I had someone give me advice beforehand. This is what I already know to do/not do: -Get everything in writing -Limit the scope of the project. Once I start the actually coding, all features should be frozen. -Make sure to communicate constantly with my client. In addition he wants an max hourly cap. What is a good way to come up with one? What else do I need to know?

  • Social Media JSR 357 NOT approved by Executive Committee

    - by alexismp
    JSR 357 (Social Media API) has not passed the initial ballot which means, according to the JCP rules, that "the JSR submitter(s) who may revise the JSR and resubmit it within 14 days". Given the comments associated with the negative votes, it may be challenging for the submitters to address the concerns about the scope assessed by many as being too wide. Standardization is a difficult task and the JCP (the Executive Committee in fact) played its role by pointing out the challenges ahead of such a JSR as it was envisioned by its submitters, and thus the risk of never completing. If anything this proves that the JCP is working as expected. For those disappointed that Java will not get a standard "Social Media API" (for now at least), let me remind you of the recent open-sourcing of DaliCore.

  • Do I own copyright of program I made in own time?

    - by Dave Mess
    I created a software package that aids electrical engineers with common calculations used on site (substations to be specific). I created the package in my own time, without being asked and without guidance. The package is now widely used within my company and I intend to distribute it nationally. Do I own the copyright? My contract does state that all work produced is theirs, but this was outside of work and outside of my 'scope of work'. My company is mainly a civil and construction company and had no influence in the creation of the program. From comments: This is the paragraph "During the course of your service, you will disclose to the company all information, formulae, processes, inventions or improvements which you have learned, discovered or evolved during the course of your service or in connection with the business of the company and will sign any necessary documents to enable the company to obtain patent protection whether still in the company service or not. " They are taking it seriously and have got their lawyers.

  • Should I create repositories with special functions like getStaffActive()?

    - by Parhs
    I have seen lots of articles but none really help me. That is because I want to use dapper as a DAL. Should I create repositories with special functions? Like getStaffActive()? If I use repositories I can implement with dapper-extension a generic crud I have no idea how to handle database connection. Where to open the connection? If I do this at every function then how am I supposed to use transaction scope? Somehow the repositories I work with should share a connection in order transaction to work. But how to do this? Openning connection in BLL? If I use queries and execute them directly then still the same thing.

  • How to specify ingredients in Schema.org (other than recipes or drugs)?

    - by guillem
    I'd like to use Schema.org for a series of product specs pages. The products are cosmetics (shampoos, creams, etc.) and ideally an INCI declaration will be included for every product. I'd like to use Schema.org in the declaration, but I cannot find a suitable category in Schema.org. Ingredients is meant for cooking recipes, and ActiveIngredient for (medical) drugs and dietary supplements. Did I overlook some part of the tree? Any ideas for a workaround? Or am I trying to do something out of scope?

  • ignore this test

    - by Name
    http://markitup.jaysalvat.com/downloads/markupsets/wiki/set.js Here is a useful construct when trying to hide variables from the parent namespace. All the code within the function is contained in the private scope of the function, meaning it is allowed. So you've become comfortable with jQuery and would like to learn how to write your own plugins. Great! You're in the right spot. Extending jQuery with plugins and methods is very powerful and can save you and your peers a lot of development time by abstracting your most clever functions into plugins. This post will outline the basics, best practices, and common pitfalls to watch out for as you begin writing your plugin.

  • Application of LGPL license on a simple algorithm

    - by georgesl
    The "scope" of the GNU license is troubling me : I know it has been answered many times ( here, here, ... ) but shouldn't we take into consideration the complexity and originality of a code before using GPL license ? I explain : I'm working on a pet project using the DTW algorithm that I have written in C using the pseudo-code given on the wikipedia page . At one point I decided to change it for a C++ implementation ( just for hone my c++ skill ) . After doing so, I've looked for an existing implementation on the web, to compare the "cleanliness" of it, and I found this one : Vectored DTW implementation, which is part of limproved, a C++ library licensed under GPL v3 . Personnally, I don't mind the GNU license because it is a personnal project, which will never led to any kind of commercial purpose, but I wonder if this implementation can abide a company using it to open their code ( and other FOSS permissions ). Theoretically, I think it can ( I may be wrong :p ), but the algorithm in question is so simple (and old) that it should not.

  • MSDTC - Communication with the underlying transaction manager has failed (Firewall open, MSDTC netwo

    - by SocialAddict
    I'm having problems with my ASP.NET web forms system. It worked on our test server but now we are putting it live one of the servers is within a DMZ and the SQL server is outside of that (on our network still though - although a different subnet) I have open up the firewall completely between these two boxes to see if that was the issue and it still gives the error message "Communication with the underlying transaction manager has failed" whenever we try and use the "TransactionScope". We can access the data for retrieval it's just transactions that break it. We have also used msdtc ping to test the connection and with the amendments on the firewall that pings successfully, but the same error occurs! How do i resolve this error? Any help would be great as we have a system to go live today. Panic :) Edit: I have created a more straightforward test page with a transaction as below and this works fine. Could a nested transaction cause this kind of error and if so why would this only cause an issue when using a live box in a dmz with a firewall? AuditRepository auditRepository = new AuditRepository(); try { using (TransactionScope scope = new TransactionScope()) { auditRepository.Add(DateTime.Now, 1, "TEST-TRANSACTIONS#1", 1); auditRepository.Save(); auditRepository.Add(DateTime.Now, 1, "TEST-TRANSACTIONS#2", 1); auditRepository.Save(); scope.Complete(); } } catch (Exception ex) { Response.Write("Test Error For Transaction: " + ex.Message + "<br />" + ex.StackTrace); } This is the ErrorStack we are getting when the problem occurs: at System.Transactions.TransactionInterop.GetOletxTransactionFromTransmitterPropigationToken(Byte[] propagationToken) at System.Transactions.TransactionStatePSPEOperation.PSPEPromote(InternalTransaction tx) at System.Transactions.TransactionStateDelegatedBase.EnterState(InternalTransaction tx) at System.Transactions.EnlistableStates.Promote(InternalTransaction tx) at System.Transactions.Transaction.Promote() at System.Transactions.TransactionInterop.ConvertToOletxTransaction(Transaction transaction) at System.Transactions.TransactionInterop.GetExportCookie(Transaction transaction, Byte[] whereabouts) at System.Data.SqlClient.SqlInternalConnection.GetTransactionCookie(Transaction transaction, Byte[] whereAbouts) at System.Data.SqlClient.SqlInternalConnection.EnlistNonNull(Transaction tx) at System.Data.SqlClient.SqlInternalConnection.Enlist(Transaction tx) at System.Data.SqlClient.SqlInternalConnectionTds.Activate(Transaction transaction) at System.Data.ProviderBase.DbConnectionInternal.ActivateConnection(Transaction transaction) at System.Data.ProviderBase.DbConnectionPool.GetConnection(DbConnection owningObject) at System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection) at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory) at System.Data.SqlClient.SqlConnection.Open() at System.Data.Linq.SqlClient.SqlConnectionManager.UseConnection(IConnectionUser user) at System.Data.Linq.SqlClient.SqlProvider.get_IsSqlCe() at System.Data.Linq.SqlClient.SqlProvider.InitializeProviderMode() at System.Data.Linq.SqlClient.SqlProvider.System.Data.Linq.Provider.IProvider.Execute(Expression query) at System.Data.Linq.ChangeDirector.StandardChangeDirector.DynamicInsert(TrackedObject item) at System.Data.Linq.ChangeDirector.StandardChangeDirector.Insert(TrackedObject item) at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges() at RegBook.classes.DbBase.Save() at RegBook.usercontrols.BookingProcess.confirmBookingButton_Click(Object sender, EventArgs e)

  • WpfToolkit DataGrid does not work in Windows Phone 7

    - by Igor Zevaka
    I am trying to use WpfToolkit DataGrid in Windows Phone 7 project (Silverligt 4) and it's not working. Here is the XAML: <UserControl x:Class="SilverlightControls.Grid" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" xmlns:wtk="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" d:DesignHeight="480" d:DesignWidth="480"> <Grid x:Name="LayoutRoot" Background="#FF1F1F1F" Width="960"> <Grid x:Name="TitleGrid"> <TextBlock Text="{Binding Title}" Style="{StaticResource PhoneTextPageTitle2Style}"/> </Grid> <wtk:DataGrid> </wtk:DataGrid> </Grid> </UserControl> The project compiles fine but crashes at runtime trying to load this control. The best clue I got so far is from Visual Studio Designer. Once I add wtk:DataGrid to the control the visual designer does not load and below is the exception it displays.

  • Eclipse PDT debugging web application: evaluating expressions in a console

    - by dreftymac
    When using Eclipse PDT with XDebug to debug a PHP web application, is there any way to open up a console window that will allow me to type in and see the value of arbitrary expressions in the current scope? This would seem like an obvious element of the debugging environment, and I may be missing something, but the only thing resembling a console says "no consoles to display at this time"

  • EJB3 Transaction Propogation

    - by Matt S.
    I have a stateless bean something like: @Stateless public class MyStatelessBean implements MyStatelessLocal, MyStatelessRemote { @PersistenceContext(unitName="myPC") private EntityManager mgr; @TransationAttribute(TransactionAttributeType.SUPPORTED) public void processObjects(List<Object> objs) { // this method just processes the data; no need for a transaction for(Object obj : objs) { this.process(obj); } } @TransationAttribute(TransactionAttributeType.REQUIRES_NEW) public void process(Object obj) { // do some work with obj that must be in the scope of a transaction this.mgr.merge(obj); // ... this.mgr.merge(obj); // ... this.mgr.flush(); } } The typically usage then is the client would call processObjects(...), which doesn't actually interact with the entity manager. It does what it needs to do and calls process(...) individually for each object to process. The duration of process(...) is relatively short, but processObjects(...) could take a very long time to run through everything. Therefore I don't want it to maintain an open transaction. I do need the individual process(...) operations to operate within their own transaction. This should be a new transaction for every call. Lastly I'd like to keep the option open for the client to call process(...) directly. I've tried a number of different transaction types: never, not supported, supported (on processObjects) and required, requires new (on process) but I get TransactionRequiredException every time merge() is called. I've been able to make it work by splitting up the methods into two different beans: @Stateless @TransationAttribute(TransactionAttributeType.NOT_SUPPORTED) public class MyStatelessBean1 implements MyStatelessLocal1, MyStatelessRemote1 { @EJB private MyStatelessBean2 myBean2; public void processObjects(List<Object> objs) { // this method just processes the data; no need for a transaction for(Object obj : objs) { this.myBean2.process(obj); } } } @Stateless public class MyStatelessBean2 implements MyStatelessLocal2, MyStatelessRemote2 { @PersistenceContext(unitName="myPC") private EntityManager mgr; @TransationAttribute(TransactionAttributeType.REQUIRES_NEW) public void process(Object obj) { // do some work with obj that must be in the scope of a transaction this.mgr.merge(obj); // ... this.mgr.merge(obj); // ... this.mgr.flush(); } } but I'm still curious if it's possible to accomplish this in one class. It looks to me like the transaction manager only operates at the bean level, even when individual methods are given more specific annotations. So if I mark one method in a way to prevent the transaction from starting calling other methods within that same instance will also not create a transaction, no matter how they're marked? I'm using JBoss Application Server 4.2.1.GA, but non-specific answers are welcome / preferred.

  • IronPython and Nodebox in C#

    - by proxylittle
    My plan: I'm trying to setup my C# project to communicate with Nodebox to call a certain function which populates a graph and draws it in a new window. Current situation: [fixed... see Update2] I have already included all python-modules needed, but im still getting a Library 'GL' not found it seems that the pyglet module needs a reference to GL/gl.h, but can't find it due to IronPython behaviour. Requirement: The project needs to stay as small as possible without installing new packages. Thats why i have copied all my modules into the project-folder and would like to keep it that or a similar way. My question: Is there a certain workaround for my problem or a fix for the library-folder missmatch. Have read some articles about Tao-Opengl and OpenTK but can't find a good solution. Update1: Updated my sourcecode with a small pyglet window-rendering example. Problem is in pyglet and referenced c-Objects. How do i include them in my c# project to be called? No idea so far... experimenting alittle now. Keeping you updated. SampleCode C#: ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(null); ScriptRuntime runtime = new ScriptRuntime(setup); ScriptEngine engine = Python.GetEngine(runtime); ScriptSource source = engine.CreateScriptSourceFromFile("test.py"); ScriptScope scope = engine.CreateScope(); source.Execute(scope); SampleCode Python (test.py): from nodebox.graphics import * from nodebox.graphics.physics import Vector, Boid, Flock, Obstacle flock = Flock(50, x=-50, y=-50, width=700, height=400) flock.sight(80) def draw(canvas): canvas.clear() flock.update(separation=0.4, cohesion=0.6, alignment=0.1, teleport=True) for boid in flock: push() translate(boid.x, boid.y) scale(0.5 + boid.depth) rotate(boid.heading) arrow(0, 0, 15) pop() canvas.size = 600, 300 def main(canvas): canvas.run(draw) Update2: Line 139 [pyglet/lib.py] sys.platform is not win32... there was the error. Fixed it by just using the line: from pyglet.gl.lib_wgl import link_GL, link_GLU, link_WGL Now the following Error: 'module' object has no attribute '_getframe' Kind of a pain to fix it. Updating with results... Update3: Fixed by adding following line right after first line in C#-Code: setup.Options["Frames"] = true; Current Problem: No module named unicodedata, but in Python26/DLLs is only a *.pyd file`. So.. how do i implement it now?!

    Hi guys, I'm writing an application with GWT and I found on the internet that there's a library to use easily gdata features. In particular I need to use the integration with Google Calendar. I followed the official guide on gwt-gdata site to do the authentication ( http://code.google.com/p/gwt-gdata/wiki/GettingStarted ) but unfortunately, I got an error. This is the error: 17:59:12.463 [ERROR] [testmappa] Unable to load module entry point class testMappa.client.TestMappa (see associated exception for details) com.google.gwt.core.client.JavaScriptException: (TypeError): $wnd.google.accounts is undefined fileName: http://127.0.0.1:8888 lineNumber: 29 stack: ("http://www.google.com/calendar/feeds/")@http://127.0.0.1:8888:29 connect("http://127.0.0.1:8888/TestMappa.html?gwt.codesvr=127.0.0.1:9997","`gL1<a3s4B&Y{(Ci","127.0.0.1:9997","testmappa","2.0")@:0 ((void 0),"testmappa","http://127.0.0.1:8888/testmappa/")@http://127.0.0.1:8888/testmappa/hosted.html?testmappa:264 z()@http://127.0.0.1:8888/testmappa/testmappa.nocache.js:2 (-2)@http://127.0.0.1:8888/testmappa/testmappa.nocache.js:8 at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:195) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:120) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:507) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java:264) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java:91) at com.google.gwt.accounts.client.User.login(User.java) at testMappa.client.TestMappa.onModuleLoad(TestMappa.java:68) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.ModuleSpace.onLoad(ModuleSpace.java:369) at com.google.gwt.dev.shell.OophmSessionHandler.loadModule(OophmSessionHandler.java:185) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java:380) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java:222) at java.lang.Thread.run(Thread.java:637) I'm not able to understand the reason of this error. My code is simply: String scope = "http://www.google.com/calendar/feeds/"; User.login(scope); And as far as I know it should work as it is. I don't know what to do and I'm here to ask how to solve this problem and if I can directly use gdata native java library, but I believe this other thing is not possible to be done for client-side gwt code (since the code is going to be converted to javascript). Thank you.

  • Jquery Cycle Plugin Question - turning off relative links to photos so it goes to a URL

    - by alpdog14
    I am using Jquery Cycle Plugin and it has a side panel that highlights as the photos change and currently when I click on the text the associated photo pulls up then I have to click on the photo to go to the URL but I would like the text itself to link to the URL. I have looked at the fn.cycle.defaults but not sure what to change and I tried a few things but nothing works. If anyone can help me figure this out it would be most helpful. Here are the fn.cycle.defaults: fx: 'fade', // one of: fade, shuffle, zoom, scrollLeft, etc timeout: 4000, // milliseconds between slide transitions (0 to disable auto advance) continuous: 0, // true to start next transition immediately after current one completes speed: 1000, // speed of the transition (any valid fx speed value) speedIn: null, // speed of the 'in' transition speedOut: null, // speed of the 'out' transition next: null, // id of element to use as click trigger for next slide prev: null, // id of element to use as click trigger for previous slide prevNextClick: null, // callback fn for prev/next clicks: function(isNext, zeroBasedSlideIndex, slideElement) pager: null, // id of element to use as pager container pagerClick: null, // callback fn for pager clicks: function(zeroBasedSlideIndex, slideElement) pagerEvent: null, // event which drives the pager navigation pagerAnchorBuilder: null, // callback fn for building anchor links before: null, // transition callback (scope set to element to be shown) after: null, // transition callback (scope set to element that was shown) end: null, // callback invoked when the slideshow terminates (use with autostop or nowrap options) easing: null, // easing method for both in and out transitions easeIn: null, // easing for "in" transition easeOut: null, // easing for "out" transition shuffle: null, // coords for shuffle animation, ex: { top:15, left: 200 } animIn: null, // properties that define how the slide animates in animOut: null, // properties that define how the slide animates out cssBefore: null, // properties that define the initial state of the slide before transitioning in cssAfter: null, // properties that defined the state of the slide after transitioning out fxFn: null, // function used to control the transition height: 'auto', // container height startingSlide: 0, // zero-based index of the first slide to be displayed sync: 1, // true if in/out transitions should occur simultaneously random: 0, // true for random, false for sequence (not applicable to shuffle fx) fit: 0, // force slides to fit container pause: true, // true to enable "pause on hover" autostop: 0, // true to end slideshow after X transitions (where X == slide count) autostopCount: 0, // number of transitions (optionally used with autostop to define X) delay: 0, // additional delay (in ms) for first transition (hint: can be negative) slideExpr: null, // expression for selecting slides (if something other than all children is required) cleartype: 0, // true if clearType corrections should be applied (for IE) nowrap: 0 // true to prevent slideshow from wrapping }; I have tried changing the pageClick and pagerEvent but nothing seems to be working. Please help!!!

  • Use of XMLHttpRequest in Dashboard widget failing

    - by Peter Zion
    I am unable to get an XMLHttpRequest object to work correctly in a Dashboard widget I am writing. I've isolated it to a trivial example not working in the global scope of the main.js file: xhr = new XMLHttpRequest; xhr.open( 'GET', "http://google.com", false ); xhr.send(''); When the last line is executed I get the error "ABORT_ERR: XMLHttpRequest Exception 102" (this is in the Dashcode debugger). Does anyone have any idea what could be wrong here?
