• How to tell binary from text files in linux

  - by gabor

  The linux file command does a very good job in recognising file types and gives very fine-grained results. The diff tool is able to tell binary files from text files, producing a different output. Is there a way to tell binary files form text files? All I want is a yes/no answer whether a given file is binary. Because it's difficult to define binary, let's say I want to know if diff will attempt a text-based comparison. To clarify the question: I do not care if it's ASCII text or XML as long as it's text. Also, I do not want to differentiate between MP3 and JPEG files, as they're all binary.

• RESTful web services - best way to return result of an operation?

  - by saille

  I am designing a RESTful API and I would like to know what the most RESTful way is to return details about an operation. E.g. an operation on a resource occurs when some data is POSTed to a URL. HTTP status codes will indicate either success or failure for the operation. But apart from success/failure I need to indicate some other info to the client, such as an ID number. So my question is, should the ID number be returned in an XML document in the response content, or should it be returned in some custom HTTP header fields? Which is more in line with the principles of REST? Or am I free to choose.

• file operations

  - by devtech

  I am writing a script for renaming/copying the content of a file. I have temp & temp1 folders. Inside temp1 I have 1000 .txt files with names 1.txt, 2.txt, 3.txt ... & in temp folder I have sub directories named 1, 2, 3. In the folders 1, 2, 3 ..., I have one file with extension java or xml. My need is to automate the copy of the contents of the .txt file, and paste into the respective file in the temp sub directory. Is it possible to do this using Perl?

• Grouping data in an NSMutable array

  - by padatronic

  Hi guys, I have an array i load with lots of data from an xml file. I am displaying this on a tableview and then when you click on say an author it goes through to display all their books.

• Disable keyboard on EditText

  - by Ferox

  I'm doing a calculator. So I made my own Buttons with numbers and functions. The expression that has to be calculated, is in an EditText, because I want users can add numbers or functions also in the middle of the expression, so with the EditText I have the cursor. But I want to disable the Keyboard when users click on the EditText. I found this example that it's ok for Android 2.3, but with ICS disable the Keyboard and also the cursor. public class NoImeEditText extends EditText { public NoImeEditText(Context context, AttributeSet attrs) { super(context, attrs); } @Override public boolean onCheckIsTextEditor() { return false; } } And then I use this NoImeEditText in my XML file <com.my.package.NoImeEditText android:id="@+id/etMy" .... /> How I can make compatible this EditText with ICS??? Thanks.

• Upgrading a SharePoint list instance that was deployed via feature

  - by Goldmember

  I'm curious how others address this issue. Using VSEWSS 1.3, I have created a site content type, a list definition (w event receivers), and a list instance. All of them are in the same WSP solution and each is activated individually via features. Now let's assume that all the features have been activated for some time, and the list instance contains a number of items (that can't be deleted). Now suppose I need to make a change to the schema.xml (inject some javascript, modify views, whatever) of the list. Is it even possible to "upgrade" the schema of the existing list instance? Otherwise I would think I'm stuck creating a new instance and copying items over.

• How to Compile Sample Code

  - by James L

  I'm breaking into GUI programming with android, trying to compile and analyze Lunar Lander sample program. The instructions for using Eclipse say to select "Create project from existing source" but that option doesn't exist. If I select File-New-Project I can select "Java project from Existing Ant Buildfile". Using that I've tried selecting various xml files as "Ant Buildfile" but all give me the "The file selected is not a valid Ant buildfile" error. I just want to run GUI sample projects, preferably with Eclipse. Any useful tips will be appreciated.

• xmlCtxtGetLastError - Iphone

  - by Raphael Kohn

  Hi, I have been programming with NSXMLParser for quite a while and lately, I came out with this error. The strangiest thing is that it only happens in debug mode. Once I load the App in Simulator and run it from Simulator (without Xcode involved), it runs fine. The code is very straight foward, it is a simple XML parsing whose contents were loaded from the web in a separated thread. Does anybody have alredy encoutered that error?? Thanks in advance.

• Multiple Grails Applications create Ehcache conflicts

  - by Lloyd Meinholz

  I am running multiple Grails Applications on one of my servers. I am using Grails 1.2.2. I am using the default cache configuration in DataSource.groovy. When I try and run two Grails applications, they both seem to be using/writing to: /tmp/org.hibernate.cache.UpdateTimestampsCache.data When I look at how to customize Ehcache with an ehcache.xml file from this page: http://ehcache.org/documentation/grails.html I do not see any information about specifying the locations and/or names or temporary files. How do I avoid this issue when running multiple Grails applications on the same server (without turning off the cache)?

• JAXB - representing an element as a boolean member?

  - by Marcus

  We have this XML: <Summary> <ValueA>xxx</ValueA> <ValueB/> </Summary> <ValueB/> will never have any attributes or inner elements. It's a boolean type element - it exists (true) or it doesn't (false). JAXB generated a Summary class with a String valueA member, which is good. But for ValueB, JAXB generated a ValueB inner class and a corresponding member: @XmlElement(name = "ValueB") protected Summary.ValueB valueB; But what I'd like is a boolean member and no inner class: @XmlElement(name = "ValueB") protected boolean valueB; How can you do this? I'm not looking to regenerate the classes, I'd like to just make the code change manually.

• Inserting nil Values into Sqlite Database?

  - by Chris

  I am working on an iPhone App where I am pulling data from an XML file and inserting it into a sqlite database located in the App. I am able to successfully do this process, but it appears that if I try to sqlite3_bind_text with a NSString that has a value of "nil", the App quickly dies. This is an example of code that fails: (modified for this example) // idvar = 1 // valuevar = nil const char *sqlStatement = "insert into mytable (id, value) VALUES(?, ?)"; sqlite3_stmt *compiledStatement = nil; sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL); sqlite3_bind_int(compiledStatement, 1, [idvar intValue]);; sqlite3_bind_text(compiledStatement, 2, [valuevar UTF8String], -1, SQLITE_TRANSIENT);

• Ruby on Rails: reducing complexity of parameters in a RESTFul HTTP POST request (multi-model)

  - by randombits

  I'm using cURL to test a RESTFul HTTP web service. The problem is I'm normally submitting a bunch of values normally like this: curl -d "firstname=bob&lastname=smith&age=25&from=kansas&someothermodelattr=val" -H "Content-Type: application/x-www-form-urlencoded" http://mysite/people.xml -i The problem with this is my controller will then have code like this: unless params[:firstname].nil? end unless params[:lastname].nil? end // FINALLY @person = People.new(params[:firstname], params[:lastname], params[:age], params[:from]) etc.. What's the best way to simplify this? My Person model has all the validations it needs. Is there a way (assuming the request has multi-model parameters) that I can just do: @person = People.new(params[:person]) and then the initializer can take care of the rest?

• Using Java server-side with PHP front-end

  - by Storm

  Hi!  Does anyone have a real-world experience in building such a project? I'd like to move away questions about "is it good idea or not", but focus on possible solutions. I see one simple way - HTTP GET/POST + xml/json - and one more elegant - AJAX/DWR. As for the first one - I understand that it is possible, but needs quite a lot coding. As for second way - is it possible to use Java DWR engine with PHP front-end? Is DWR language-independent for client side (as it uses just JavaScript)?  Would it be a problem, that client page was generated by one web server (for example, apache+php) and served on server-side by another (for example, tomcat)? I suspect, that Tomcat will complain about sessions. Can this problem be fixed with allowing cross-domain AJAX? Thank you in advance. Denis.

• Two different tables or just one with bool column?

  - by Aidas

  We have two tables: OriginalDocument and ProcessedDocument. In the first one we put an original, not processed document. After it's validated and processed (converted to our xml format and parsed), it's put into Document table. Processed document can be valid or invalid. Which makes more sense: have two different tables for valid and invalid documents or just have one with 'Valid' column? Some of the columns (~5-7) are irrelevant for invalid document. Storing both invalid and valid documents would also make Document table filled with 'NULL' columns (if document is invalid, information like document number, receiver can be unknown). What else should we consider and weigh, when making this decision?

• How do I host a Google gadget? How does it work?

  - by sintaloo

  I just spent 5 hours by checking Google gadgets websites and FAQs, but I still have no idea how to host a gadget. What I've figured from reading the Google documentation: I can write gadgets with XML, JavaScript etc.. Gadgets can be added to iGoogle etc.. Google can host the gadgets for you. Gadgets can be hosted anywhere else??? All of the above information doesn't answer my question. For instance, with jQuery or Dojo Toolkit, I can download the JavaScript framework and use it. With Google gadgets, I can not find a download link for a framework. Why? Does Google provide its framework? If not, why does the documentation indicate that gadgets can be hosted anywhere? I am totally confused. A brief explanation or some helpful links are very welcome! Thanks a lot!!!

• Tomcat not showing Spring Context initialization errors when running from Eclipse WTP

  - by SourceRebels

  Hi all, Im working with Eclipse Galileo (WTP), Spring 2.5.6-SEC01 and Apache Tomcat 5.5.28. When I run my application from Eclipse, I'm able to see Tomcat standard output and error from the console view. When there is a Spring initialization error (ex: malformed spring XML) I'm not able to see the error message or the stacktrace at the Console view. Anyone found before a problem like this? how you solve it? Thanks in advance, I'm getting mad :-) Edited: I'm seeing all Tomcat startup messages and my System.out.println and System.err.println messages in Eclipse Console. I also try to pass this two system properties to my Tomcat Server: -Djava.util.logging.manager="org.apache.juli.ClassLoaderLogManager" -Djava.util.logging.config.file="C:\apache-tomcat-5.5.28\conf\logging.properties"

• How to store or share live data between PHP Requests?

  - by Devyn

  Hi, I want to start a project for facebook and the application will be like real-time multiplayer chess game. The problem I'm having is I have no idea how to store the data when a player moves one piece and update the new position in player2 browser. I'm gonna use PHP, MySQL for server side and jQuery for Client Rendering. The simplest idea is to store the data in XML or MySQL and re-generate the result to player2 browser. But I know that when thousand of players are playing, it will not be an efficient way. Since I don't have time to study new language for this project, I'm gonna have to stick with PHP. I'm not going to use flash either because I want my client side light-weight and flash-free. So is there any way that will solve my problems?

• Sending the variable's content to my mailbox in Python?

  - by brilliant

  I have asked this question here about a Python command that fetches a URL of a web page and stores it in a variable. The first thing that I wanted to know then was whether or not the variable in this code contains the HTML code of a web-page: from google.appengine.api import urlfetch url = "http://www.google.com/" result = urlfetch.fetch(url) if result.status_code == 200: doSomethingWithResult(result.content) The answer that I received was "yes", i.e. the variable "result" in the code did contain the HTML code of a web page, and the programmer who was answering said that I needed to "check the Content-Type header and verify that it's either text/html or application/xhtml+xml". I've looked through several Python tutorials, but couldn't find anything about headers. So my question is where is this Content-Type header located and how can I check it? Could I send the content of that variable directly to my mailbox? Here is where I got this code. It's on Google App Engines.
