• Combined states, FSM

  - by bobobobo

  Not sure this is the right place to ask, but is it "correct" to combine states of an FSM? Say you have an object with enum State { State1 = 1 << 0, State2 = 1 << 1, State3 = 1 << 2 } ; It just so happens that it makes sense to combine states, as in State myState = State1 | State2 ; however in FSM theory is this illegal?

• Does Microsoft still sell FAST ESP?

  - by Kunal Sen

  I wanted some information about FAST ESP search engine. After failing to get any response from the email query system on Microsoft site I called their ore-sales phone number. The person there told me the only way they sell FAST ESP is as a bundled product with SharePoint. That really does not make any sense and contradicts all the PDF documents they have about FAST ESP on their site. Does anyone know who to contact at Microsoft to discuss this product?

• Eclipse RCP File Explorer

  - by yournamehere

  Is there a good Eclipse RCP file explorer out there? I need a platform independent file explorer which should be extensible through plugins. I only found File Arranger , wich seems to be outdated. I just ask cause i want to develop such an explorer, but it wouldn't make sense if there is already a solution out there.

• Python editor with automatic code completion?

  - by netvope

  I have seen various articles about good Python editors/IDEs, like this. However, none of them points out whether the editors support automatic code completion. I tried notepad++, PyScript and Komodo Edit, but all of these requires a hotkey to invoke the code completion dialog. Do you know any Python editors with automatic code completion?

• Creating a custom device for Swing/AWT to draw to

  - by beta

  I am working on an embedded linux device that requires custom java code to draw to the screen. I was wondering if there was any way to create a custom adapter that can update the display based off our drawing code. I have done some digging and haven't found any information as to how Devices are implemented or plugged into Swing/AWT. Any information is greatly appreciated. Thanks.

• TextMate - must-have Bundles and Plugins for web dev

  - by dscher

  Just curious what experienced Textmate users can't live without in the program. I just ran the trial and bought the program so I'm trying to get a sense of how others might setup their development environment for web development. Also, based on the fact that I just bought the program, I am going to guess that TM2 will come out next week. Yes, that's right, next week. Unfortunately, because of my luck, it will not be a free upgrade...upgrades will cost more.

• Embedding a font in delphi

• Cross developping targetting both Java Swing and GWT

  - by WizardOfOdds

  Does anyone know of any tool that can facilitate/ease porting of an app to both Java Swing and GWT? I've got a few "screens" that makes complete sense to have both in a desktop app and in a browser and I was wondering if there was some kind of common API that could be targetted that would facilitate creating these two different "views" (see my comment)?

• PHP REST Clients

  - by Jamie Rumbelow

  I'm trying to connect to a RESTful web service, but I'm having some troubles, especially when sending data over PUT and DELETE. With cURL, PUT requires a file to send, and DELETE is just weird. I'm perfectly capable of writing a client using PHP's socket support and writing the HTTP headers myself, but I wanted to know whether you guys have ever used or seen a REST client for PHP?

• How to return a file result when I don't know the content type

  - by Jim Geurts

  I have an asp.net mvc action that returns a file result. Behind the scenes, it's just returning a file from a directory. FilePathResult requires a content type, but I don't know that. What is the proper way to return a file result if I only have the path to the file available?

• Javascript iFrame Limitations

  - by Matrym

  I know that, for security reasons, javascript can't read the contents of an iframe if it belongs to a different domain. This makes sense, given that the entire page could be an iframe with snooping scripts outside of the frame. The question is - are there equal limitations in the other direction? Can javascript within an iframe (from a different domain) read and manipulate the dom in its parent window? Thanks!

  I am attempting to have mechanize select a form from a page, but the form in question has no "name" attribute in the html. What should I do? when I try to use br.select_form(name = "") i get errors that no form is declared with that name, and the function requires a name input. There is only one form on the page, is there some other way I can select that form?

• jQuery.ajax(): discard slow requests

  - by Thomas

  I've build a livesearch with the jQuery.ajax() method. On every keyup events it receives new result data from the server. The problem is, when I'm typing very fast, e.g. "foobar" and the GET request of "fooba" requires more time than the "foobar" request, the results of "fooba" are shown. To handle this with the timeout parameter is impossible, I think. Has anyone an idea how to solve this?

• Why are there so many Database Management Systems?

  - by mr.bio

  Why are there so many Database management systems? I am not an DB expert and I've never thought about using another Database other than mySQL. Programming languages offer different paradigms, so it makes sense to choose a specific language for your purpose. Question What are the factors in choosing a specific Database management system ?

• Oracle thin driver vs. OCI driver. Pros and Cons?

  - by Zwei Steinen

  Hi, When you develop a Java application that talks to oracle DBs, there are 2 options right? One is oracle thin driver, and the other is OCI driver that requires its own installation (please correct if I'm misunderstanding). Now, what are the pros and cons? Obviously thin driver sounds much better in terms of installation, but is there anything that OCI can and the thin one can't? Develop environment is Tomcat6 + Spring 3.0 + JPA(Hibernate) + appache-DBCP Thanks in advance.

• Problem with upper-case and lower-case xpath functions in selenium IDE

  - by Aristotelis

  Hi, I am trying to get a xpath query using the xpath function lower-case or uppper-case, but they seem to not work in selenium (where I test my xpath before I apply it). Example that does NOT work: //*[.=upper-case('some text')] I have no problem locating the nodes I need in complex path and even using aggregated functions, as long as I don't use the upper and lower case. Has anyone encountered this before? Does it make sense? Thanks.

• Can I connect to an Oracle database from C# in a way that will work in a mono environment (on Linux)

  - by fantius

  Obviously I'd like to not have to install a Oracle client (other than simply a DLL), because that would prohibit my ClickOnce goal. I tried System.Data.OracleClient, but it threw an exception, "System.Data.OracleClient requires Oracle client software version 8.1.7 or greater." Thanks in advance.

• How can Swing dialogs even work?

  - by Bart van Heukelom

  If you open a dialog in Swing, for example a JFileChooser, it goes somewhat like this pseudocode: swing event thread { create dialog add listener to dialog close event { returnValue = somethingFromDialog } show dialog (wait until it is closed) return returnValue } My question is: how can this possibly work? As you can see the thread waits to return until the dialog is closed. This means the Swing event thread is blocked. Yet, one can interact with the dialog, which AFAIK requires this thread to run. So how does that work?

• Listing defined functions in bash

  - by Charles Duffy

  I'm trying to write some code in bash which uses introspection to select the appropriate function to call. Determining the candidates requires knowing which functions are defined. It's easy to list defined variables in bash using only parameter expansion: $ prefix_foo="one" $ prefix_bar="two" $ echo "${!prefix_*}" prefix_bar prefix_foo However, doing this for functions appears to require filtering the output of set -- a much more haphazard approach. Is there a Right Way?

• Why does a JRuby application on App Engine take so long to start?

  - by Major Tom

  I'm considering using JRuby on App Engine but have heard that Juby app on App Engine have a long startup lag. Why is this? Is it because the JRuby jar files are so large that a cold startup requires them to be loaded into memory before the app can start serving? That would be my guess but I'm not sure if that's a precise technical explanation.
