• command line merge tools for windows

  - by hasen j

  Are there command line merge tools for windows? I'm thinking in terms of tools that can be used in conjunction with other tools (e.g. git, unison) to resolve conflicts. Actually, it doesn't need to strictly be command-line based, as long as it "cooperate" with other command line tools (as I mentioned, git for example), then it's fine.

• Generate java code in Eclipse?

  - by drozzy

  Does anyone know what approach one can take to automatically generate Java source code, from for example an xml or json file, in eclipse? One great example of what I am thinking of doing is what Google Android sdk does: they have an R class generated automatically from the resources. Every time a resource file is saved in Eclipse R class is automatically regenerated. Thanks!

• Usecase for Workflow Engine

  - by Icarus

  Hi, We have an issue where a Database table has to be updated on the status for a particular entity. Presently, its all Java code with a lot of if conditions and an update to the status. I was thinking along lines of using a Workflow engine since there can be multiple flows in future. Is it an overkill to use a Workflow Engine here... where do you draw the line ?

• Haskell optimization of a function looking for a bytestring terminator

  - by me2

  Profiling of some code showed that about 65% of the time I was inside the following code. What it does is use the Data.Binary.Get monad to walk through a bytestring looking for the terminator. If it detects 0xff, it checks if the next byte is 0x00. If it is, it drops the 0x00 and continues. If it is not 0x00, then it drops both bytes and the resulting list of bytes is converted to a bytestring and returned. Any obvious ways to optimize this? I can't see it. parseECS = f [] False where f acc ff = do b <- getWord8 if ff then if b == 0x00 then f (0xff:acc) False else return $ L.pack (reverse acc) else if b == 0xff then f acc True else f (b:acc) False

• Switch statements: do you need the last break? (Javascript mainly)

  - by Jon Raasch

  When using a switch() statement, you add break; in between separate case: declarations. But what about the last one? Normally I just leave it off, but I'm wondering if this has some performance implication I'm not thinking about? I've been wondering about this for a while and don't see it asked elsewhere on Stack-O, but sorry if I missed it. I'm mainly asking this question regarding Javascript, although I'm guessing the answer will apply to all switch() statements.

• Can WCF TCP and HTTP endpoints have the same port?

  - by dlanod

  I'm interested in one WCF server exposing both HTTP and TCP interfaces. It'll be used with Silverlight clients, so the thinking is that the HTTP interface will be for secure communications while TCP will be used the rest of the time. Is it possible for these two interfaces to use the same port in their endpoints, e.g. http://localhost:9000/ and net.tcp://localhost:9000/?

• Python: how to inherite and override

  - by Guy

  Consider this situation: I get an object of type A which has the function f. I.e: class A: def f(): print 'in f' def h(): print 'in h' and I get an instance of this class but I want to override the f function but save the rest of the functionality of A. So what I was thinking was something of the sort: class B(A): .... def f(): print 'in B->f' and the usage would be: def main(a): b = B(a) b.f() #prints "in B->f" b.h() #print "in h" How do you do such a thing?

• Delphi Clientdataset Lookup/Aggregate

  - by TheRoadrunner

  Hi, I need a little help with ClientDatasets in Delphi. What I want to achieve is a grid showing customers, where one of the columns shows the number of orders for each customer. I put a ClientDataset on a form and load Customers.xml from Delphi demo-data. Another ClienDataset is loaded with orders.xml. Relatively simple, I can define an aggregate on the orders CDS showing the total amount per customer (or the count). (See Cary Jensens article on this: http://edn.embarcadero.com/article/29272) The problem is getting this aggregate result from orders dataset into the customer dataset. It is kind of an reverse lookup, since there is a 1-n relationship between customers and orders, not an n-1 as normally in lookup scenarios. Any ideas ? Søren

• How to change the HTML text to Right-to-Left order when rendering the text within a WebBrowser.

  - by Java Doe

  hi, I am using a WebBrowser to render some HTML text. The WebBrowser is located within a rich client. I can detect the window's orientation when the rich client is launched. How do I make the text rendered within the WebBrowser to be dispayed in RTL order. I have tried body.setDir("rtl"), but it only aligned all the text in the WebBrowser to the right. It does not really reverse the content. For example, I have a photo that is displayed on the left and then a segment of text displayed on the right. After calling body.setDir("rtl"), it only aligned everything to the right in the WebBrowser, but it did not move the photo to the right, and it did not move the text to the left. Thanks a lot!

  hi everybody, i'm working on google maps in specifically on geometry controls the point is, in this example when I click in line or polygon infowindow show up, but the language is english (by default I think) can I change the language? in the tooltips i can replace the text, but in this particular case i have no place do replace it, this let me thinking that "language" is automatic, i'm wrong? best regards

• JavaScript Used As PHP

  - by Nathan Campos

  I'm now thinking to stabilish my code on Javascript, and begin to do all on it, but I want to know about it's security and flexibility compared to PHP. I want to know too, if it can be sucessfully used to develop things like forum boards, full web-sites and things like this, as PHP does.

• Converting WCF web service to Java

  - by Vitor Py

  I currently have a web service built on WCF. It's still in its infancy, so, major changes are still possible. I've been thinking on porting it from WCF to a Java-based solution since I'd like to have a Linux-based backend. What would be the best way to accomplish this "conversion"? Any advantages WCF may have that Java lacks?

• Are there legitimate uses for JavaScript's "with" statement?

  - by Shog9

  Alan Storm's comments in response to my answer regarding the with statement got me thinking. I've seldom found a reason to use this particular language feature, and had never given much thought to how it might cause trouble. Now, I'm curious as to how I might make effective use of with, while avoiding its pitfalls... So my question is, where have you found the with statement useful?

• Objects With No Behavior

  - by Patrick Donovan

  I've been teaching myself object oriented programming and I'm thinking about a situation where I have an object "Transaction", that has quite a few properties to it like account, amount, date, currency, type, etc. I never plan to mutate these data points, and calculation logic will live in other classes. My question is, is it poor Python design to instantiate thousands of objects just to hold data? I find the data far easier to work with embedded in a class rather than trying to cram it into some combination of data structures.

• What should I do during the summer?

  - by zamN

  I have just recently graduated from High School and I am looking for something productive to do over the summer. I was thinking of possibly learning a new language that can give me an edge in school or a good project to pursue that will look good on my resume for future jobs. Also how would I go about getting a job right out of high school or interning for a company for the summer? Thanks in advance.

• How do VoIP services connect to landlines?

  - by henry

  How do VoIP services, such as Skype and Yahoo, connect to landlines? We have a server connected to a landline using asterisk, so I'm thinking this server will bridge our VoIP conversation and connect it to a landline. But if this is the case, wouldn't Skype need a lot of servers placed around the whole world just to connect to landlines?

• good word whitelist to override bad word black list

  - by dangerousguy

  I've read through the discussion here... http://stackoverflow.com/questions/273516/how-do-you-implement-a-good-profanity-filter I've decided to implement a bad word filter using the badlist referenced in that thread. However I'm thinking about the scunthorpe problem. (see wikipedia I can't post the link, I'm a new user) Is there a white list of words like scunthorpe and manuscript that I can use to override a black list? (not interested in discussions about sensorship etc)

• Why is there no Constant keyword in Java?

  - by harigm

  I am curious learner of Java, and I was thinking about the topic of "CONSTANTS". I have learnt that Java allows us to declare constants by using final keyword. My question is why didn't Java introduce Constant (const) keyword. Since many people say it has come from C++, in C++ we have const keyword. Please share your thoughts.

• What is more interesting or powerful: Curry/Mercury/Lambda-Prolog/your suggestion.

  - by Bubba88

  Hi! I would like to ask you about what formal system could be more interesting to implement from scratch/reverse engineer. I've looked through some existing and rather open (open in the sense of free/open-source) projects of logical/declarative programming systems. I've decided to make up something similar in my free time, or at least to catch the general idea of implementation. It would be great if some of these systems would provide most of the expressive power and conciseness of modern academic investigations in logic and it's relation with computational models. What would you recommend to study at least at the conceptual level? For example, Lambda-Prolog is interesting particularly because it allows for higher order relations, but AFAIK (I might really be mistaken :)) is based on intuitionist logic and therefore lack the excluded-middle principle; that's generally a disatvantage for me.. I would also welcome any suggestions about modern logical programming systems which are less popular but more expressive/powerful. I guess, this question will need refactoring, but thank you in advance! :)

• Is it possible to programmatically talk to MSN messenger / Live messenger?

  - by Ceilingfish

  Hi chaps, I've been researching how to interact with the MSN messenger / Live messenger service programmatically and I can't find any real documentation on this. The documentation for the Live services only seem to implement in Javascript (they're here: http://dev.live.com/Messenger/) It would be possible to reverse engineer this API to obtain the web services that it is actually using, but I am guessing that they didn't provide the sources for a reason (which means that those web services aren't meant for direct access). However I can't find any other official APIs that allow programmatic access (more specifically no APIs that mention sockets, web services, or a proper programming language like Java or .Net). Does anyone know if an API like that exists?

• Swapping data binding in code

  - by Phil J Pearson

  I have two data-bound text boxes. One is bound to a string and the other to a number. The 'default' binding is set in XAML. Under some circumstances I need to reverse the bindings at runtime (the string is usually a prefix but sometimes it's a suffix). I have the following code in my view model, called when the window is loaded: Binding stringBinding = BindingOperations.GetBinding(view.seqLeft, TextBox.TextProperty); Binding numberBinding = BindingOperations.GetBinding(view.seqRight, TextBox.TextProperty); view.seqLeft.SetBinding(TextBlock.TextProperty, numberBinding); view.seqRight.SetBinding(TextBlock.TextProperty, stringBinding); After that the code loads the properties to which the binding refers. The problem is that the 'new' binding doesn't seem to work. What have I missed? Is there a better way?

• Good policy to force all developers in a company to use the same IDE?

  - by Henrik

  In my organization they are thinking about rolling out Eclipse company wide but I prefer using another editor (UltraEdit). I do not have any good arguments against this except subjective opinions that a developer should get to use whatever he/she wants as long as he's productive enough. This to make the developer a happy employee :-) Do you guys think its a good policy to force all developers in the same company to use the same IDE? Would there be any technical (dis)advantages of this decision?

• maven-archetype-webapp eclipse problem

  - by Bruce

  Hi all, I'm trying to create a very simple webapp with maven and eclipse, but I'm having no joy at all, in fact the reverse of joy. I go to File - New Project, select Maven Project, and select the maven-archetype-webapp. When I finish the wizard, a webapp structure gets generated but with no 'java' directory under main, just resources and webapp. So I right click on main and select new Class. The class gets created under resources (?!), and furthermore, there seems to be no compilation of it by java. I can make stupid errors and no syntax highlighting comes up. It's like java isn't recognizing it. Alternatively I have tried creating a new 'java' directory under main where it should be, but still with the same non-existent java symptoms. What gives? This is driving me insane.. Thanks all!
