• Internationalized strings in Eclipse plugin.xml file are not found when installed in Eclipse applica

  - by Ed

  Hi, I have created 2 plugins, implementing an ODA driver plugin and its UI plugin for the BIRT extension to Eclipse. My plugins both work as expected when eclipse starts up another eclipse application where I can then test the plugins I am developing. However, when I install my plugins into an Eclipse application and then start it from a Windows shortcut, the plugins work but and language keys specified in the plugin.xml files are not found. For example, in my plugin.xml file for the ODA Driver plugin I set the attributes 'id' to '%oda.data.source.id' and the data source 'defaultDisplayName' to '%data.source.name'. I then, in a file 'language.properties', have defined the values for both of these keys (where the keys don't have the preceeding % character). When running the plugins that have been installed into the dropins/plugins directory of an Eclipse application, the wizard for creating my ODA data source names is as '%data.source.name' and saves the data source in the rptdesign (XML) file with an ID of '%oda.data.source.id'. Since 'language' is not the default name for the properties file I went into the manifest for both plugins and changed the 'Bundle-Localization' attribute to 'language'. The language file is located in the root directory of both of my plugins. The properties file is definitely found, since I use the two language files to store other strings used by the plugins, looked up using a java ResourceBundle. The strings are always found whether the plugins are run from Eclipse application loading another, or when properly installed in the dropins/plugins directory of an Eclipse application. Why are the installed plugins not finding language keys reference in the plugin.xml files? There are not errors in the logs and the language.properties files are clearly accessible... Thanks in advance.

• Dreamweaver and GZIP files

  - by Vian Esterhuizen

  Hi, I've recently tried to optimize my site for speed and brandwith. Amongst many other techniques, I've used GZIP on my .css and .js files. Using PuTTY I compressed the files on my site and then used: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{HTTP:Accept-encoding} gzip RewriteCond %{HTTP_USER_AGENT} !Konqueror RewriteCond %{REQUEST_FILENAME}.gz -f RewriteRule ^(.*)\.css$ $1.css.gz [QSA,L] RewriteRule ^(.*)\.js$ $1.js.gz [QSA,L] <FilesMatch \.css\.gz$> ForceType text/css </FilesMatch> <FilesMatch \.js\.gz$> ForceType text/javascript </FilesMatch> </IfModule> <IfModule mod_mime.c> AddEncoding gzip .gz </IfModule> in my .htaccess file so that they get served properly because all my links are without the ".gz". My problem is, I cant work on the GZIP file in Dreamweaver. Is there a plugin or extension of somesort that allows Dreamweaver to temporarily uncompress thses files so it can read them? Or is there a way that I can work on my local copies as regular files, and server side they automatically get compressed when they are uploaded. Or is there a different code editor I should be using that would completely get around this? Or a just a different technique to doing this? I hope this question makes sense, Thanks

• OData / WCF Data Service - HTTP 500 Error

  - by Eric

  I have created an OData/WCF service using Visual Studio 2010 on Windows XP SP3 with all current patches installed. When I click on "view in browser", the service opens and I see the 3 tables from my EF model. However, when I add a table name ("Commands" in this case) to the end of the query string, rather than seeing the data from the table, I get an HTTP 500 error. (This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying.). I have not only followed the examples from 2 sites, but have also tried running the sample application that the blog poster sent me (that works on his machine), and still am not having any luck. The blog post is at Exposing OData from an Entity Framework Model Does anyone have an idea why this is occurring and how to resolve it? Here is the output of the "View in Browser": <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <service xml:base="http://localhost:1883/VistaDBCommandService.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app"> - <workspace> <atom:title>Default</atom:title> - <collection href="Commands"> <atom:title>Commands</atom:title> </collection> - <collection href="Databases"> <atom:title>Databases</atom:title> </collection> - <collection href="Statuses"> <atom:title>Statuses</atom:title> </collection> </workspace> </service> ============================= Thanks, Eric

• Problem connecting to Apache Derby using Hibernate configuration file in Netbeans (ERROR XSDB6)

  - by me_here

  I've created a local Apache Derby database in Netbeans, but am having problems when I try and autogenerate the POJO files, using the "Hibernate Reverse Engineering Wizard". My Hibernate configuration (generated by Netbeans from the database connection, then I added a few bits): <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Default Netbeans generated parameters --> <property name="hibernate.connection.driver_class">org.apache.derby.jdbc.EmbeddedDriver</property> <property name="hibernate.connection.url">jdbc:derby:C:/CerealDatabase</property> <property name="hibernate.connection.username">cerealuser</property> <property name="hibernate.connection.password">cerealpass</property> <!-- Additional parameters --> <property name="hibernate.dialect">org.hibernate.dialect.DerbyDialect</property> <property name="hibernate.show_sql">true</property> <property name="hibernate.default_schema">CEREALUSER</property> </session-factory> </hibernate-configuration> When I try and generate the POJOs using this configuration file, I get the message to check my configuration file, and the derby.log gives the errors: java.sql.SQLException: Failed to start database 'C:/CerealDatabase', see the next exception for details. Caused by: java.sql.SQLException: Failed to start database 'C:/CerealDatabase', see the next exception for details. Caused by: ERROR XSDB6: Another instance of Derby may have already booted the database C:\CerealDatabase. I've closed any other connections to the database before trying this, and there is no "db.lck" lock file at the time, which indicates there are no connections to the database as I understand it. Does anyone have any ideas? Help gratefully received.

• HttpWebRequest does has empty response requesting a search from Bing

  - by Jarrod Maxwell

  I have the following code that sends a HttpWebRequest to Bing. When I request the url below though it returns what appears to be an empty response when it should be returning a list of results. var response = string.Empty; var httpWebRequest = WebRequest.Create("http://www.bing.com/search?q=stackoverflow&count=100") as HttpWebRequest; httpWebRequest.Method = WebRequestMethods.Http.Get; httpWebRequest.Headers.Add("Accept-Language", "en-US"); httpWebRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Win32)"; httpWebRequest.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip,deflate"); using (var httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse) { Stream stream = null; using (stream = httpWebResponse.GetResponseStream()) { if (httpWebResponse.ContentEncoding.ToLower().Contains("gzip")) stream = new GZipStream(stream, CompressionMode.Decompress); else if (httpWebResponse.ContentEncoding.ToLower().Contains("deflate")) stream = new DeflateStream(stream, CompressionMode.Decompress); var streamReader = new StreamReader(stream, Encoding.UTF8); response = streamReader.ReadToEnd(); } } Its pretty standard code for requesting and receiving a web page. Any ideas why the response is empty? Thanks in advance. EDIT I left off a query string parameter in the url. I also had &count=100 which I have now corrected. It seems to work for values of 50 and below but returns nothing when larger. This works ok when in the browser, but not for this web request. It makes me think the issue is that the response is large and HttpWebResponse is not handling that for me the way I have it set up. Just a guess though.

• 3x3 Sobel operator and gradient features

  - by pithyless

  Reading a paper, I'm having difficulty understanding the algorithm described: Given a black and white digital image of a handwriting sample, cut out a single character to analyze. Since this can be any size, the algorithm needs to take this into account (if it will be easier, we can assume the size is 2^n x 2^m). Now, the description states given this image we will convert it to a 512-bit feature (a 512-bit hash) as follows: (192 bits) computes the gradient of the image by convolving it with a 3x3 Sobel operator. The direction of the gradient at every edge is quantized to 12 directions. (192 bits) The structural feature generator takes the gradient map and looks in a neighborhood for certain combinations of gradient values. (used to compute 8 distinct features that represent lines and corners in the image) (128 bits) Concavity generator uses an 8-point star operator to find coarse concavities in 4 directions, holes, and lagrge-scale strokes. The image feature maps are normalized with a 4x4 grid. I'm for now struggling with how to take an arbitrary image, split into 16 sections, and using a 3x3 Sobel operator to come up with 12 bits for each section. (But if you have some insight into the other parts, feel free to comment :)

• Beginner video capture and processing/Camera selection

  - by mattbauch

  I'll soon be undertaking a research project in real-time event recognition but have no experience with the programming aspect of video capture (I'm an upperclassman undergraduate in computer engineering). I want to start off on the right foot so advice from anyone with experience would be great. The ultimate goal is to track events such as a person standing up/sitting down, entering/leaving a room, possibly even shrugging/slumping in posture, etc. from a security camera-like vantage point. First of all, which cameras/companies would you recommend? I'm looking to spend ~$100, more if necessary but not much. Great resolution isn't a must, but is desirable if affordable. What about IP network cameras vs. a USB type webcam? Webcams are less expensive, but IP cameras seem like they'd be much less work to deal with in software. What features should I look for in the camera? Once I've selected a camera, what does converting its output to a series of RGB bitmaps entail? I've never dealt with video encoding/decoding so a starting point or a tutorial that will guide me up to this point would be great if anyone has suggestions. Finally, what is the best (least complicated/most efficient) way to display video from the camera plus my own superimposed images (boxes around events in progress, for instance) in a GUI application? I can work on any operating system in any language. I have some experience with win32 GUIs and Java GUIs. The focus of the project is on the algorithm and so I'm trying to get the video capture/display portion of the app done cleanly and quickly. Thanks for any responses!!

• How to call JSON asynchronous in xcode/ iphone develope

  - by Frames84

  I'm using the JSON framework hosting on Google. What and it's a news app that loads JSON feeds, when app goes off to load the feed I want to display the UIActivityIndicatorView but I've found my JSON Access code is not being called asynchronous which is locking the user interface. I have highlighted the function in the code and can't figuree out without breaking how to change the code. #import "JSON DataAccess Wrapper.h" #import "JSON.h" @implementation JSON_DataAccess_Wrapper @synthesize dataItemList; ////////////////////////////////////////////// /* START FEED CONNECTION/ HANDLE METHODS */ ////////////////////////////////////////////// - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [responseData setLength:0]; } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [responseData appendData:data]; } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { //label.text = [NSString stringWithFormat:@"Connection failed: %@", [error description]]; } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; } - (NSString *)stringWithUrl:(NSURL *)url { NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:30]; NSData *urlData; NSURLResponse *response = nil; NSError *error = nil; /* HOW TO MAKE THE CALL BELOW ASYNCHRONOUS */ urlData = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&response error:&error]; return [[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding]; } -(id) objectWithUrl:(NSURL *)url { SBJSON *jsonParser = [SBJSON new]; NSString *jsonString = [self stringWithUrl:url]; return [jsonParser objectWithString:jsonString error:NULL]; } - (NSMutableArray *) downloadJSONFeed { id response = [self objectWithUrl:[NSURL URLWithString:@"http://www.mysite.co.uk/index2.php?option=JSON"]]; NSMutableArray *feed = (NSMutableArray *) response; return feed; }

• Code Golf: Tic Tac Toe

  - by Aistina

  Post your shortest code, by character count, to check if a player has won, and if so, which. Assume you have an integer array in a variable b (board), which holds the Tic Tac Toe board, and the moves of the players where: 0 = nothing set 1 = player 1 (X) 2 = player 2 (O) So, given the array b = [ 1, 2, 1, 0, 1, 2, 1, 0, 2 ] would represent the board X|O|X -+-+- |X|O -+-+- X| |O For that situation, your code should output 1 to indicate player 1 has won. If no-one has won you can output 0 or false. My own (Ruby) solution will be up soon. Edit: Sorry, forgot to mark it as community wiki. You can assume the input is well formed and does not have to be error checked. Update: Please post your solution in the form of a function. Most people have done this already, but some haven't, which isn't entirely fair. The board is supplied to your function as the parameter. The result should be returned by the function. The function can have a name of your choosing.

• What am I missing with log4net - No log file created

• Linear Layout over relative layout

  - by Sai

  I have a relative layout for Camera preview with some overlay features. The layout file looks like the one in shown below: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" > <android.view.SurfaceView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/preview" android:layout_width="fill_parent" android:layout_height="fill_parent" > </android.view.SurfaceView> </RelativeLayout> I integrated some menu options from the android bluetooth chat example. The menu options work fine but if I click on one of the options, the app just froze. It opens a debug perspective but I am not able to understand them. The app does not seem to crash but it just froze. The layout that I am using for the menu options is: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" > <TextView android:id="@+id/title_paired_devices" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@string/title_paired_devices" android:visibility="gone" android:textColor="#fff" android:paddingLeft="5dp" /> <ListView android:id="@+id/paired_devices" android:layout_width="match_parent" android:layout_height="wrap_content" android:stackFromBottom="true" android:layout_weight="1" /> <TextView android:id="@+id/title_new_devices" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@string/title_other_devices" android:visibility="gone" android:textColor="#fff" android:paddingLeft="5dp" /> <ListView android:id="@+id/new_devices" android:layout_width="match_parent" android:layout_height="wrap_content" android:stackFromBottom="true" android:layout_weight="2" /> Can I attribute this to the fact that I am trying to overlay Linear layout over relative layout? Any suggestions to display the list of bluetooth devices over camera preview would be greatly appreciated

• Creating an MJPEG Viewer Iphone

  - by Tony

  Hey all, Im trying to make a MJPEG viewer in Objective C but I'm having a bunch of issues with it. First off, Im using AsyncSocket(http://code.google.com/p/cocoaasyncsocket/) which lets me connect to the host. Here's what I got so far NSLog(@"Ready"); asyncSocket = [[AsyncSocket alloc] initWithDelegate:self]; //http://kamera5.vfp.slu.se/axis-cgi/mjpg/video.cgi NSError *err = nil; if(![asyncSocket connectToHost:@"kamera5.vfp.slu.se" onPort:80 error:&err]) { NSLog(@"Error: %@", err); } then in the didConnectToHost method: - (void)onSocket:(AsyncSocket *)sock didConnectToHost:(NSString *)host port:(UInt16)port{ NSLog(@"Accepted client %@:%hu", host, port); NSString *urlString = [NSString stringWithFormat:@"http://kamera5.vfp.slu.se/axis-cgi/mjpg/video.cgi"]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"GET"]; //set headers NSString *_host = [NSString stringWithFormat:host]; [request addValue:_host forHTTPHeaderField: @"Host"]; NSString *KeepAlive = [NSString stringWithFormat:@"300"]; [request addValue:KeepAlive forHTTPHeaderField: @"Keep-Alive"]; NSString *connection = [NSString stringWithFormat:@"keep-alive"]; [request addValue:connection forHTTPHeaderField: @"Connection"]; //get response NSHTTPURLResponse* urlResponse = nil; NSError *error = [[NSError alloc] init]; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; NSLog(@"Response Code: %d", [urlResponse statusCode]); if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300) { NSLog(@"Response: %@", result); //here you get the response } } This calls the MJPEG stream, but it doesn't call it to get more data. What I think its doing is just loading the first chunk of data, then disconnecting. Am I doing this totally wrong or is there light at the end of this tunnel? Thanks!

• How do I dynamically create a document for download in Javascript?

  - by Nelson

  I'm writing some Javascript code that generates an XML document in the client (via Google Earth plugin). I'd like the user to be able to click a button on the page and be prompted to save that XML to a new file. If I were generating the XML server-side this would be easy, just make the button open the link. But the XML is generated client-side. I've come up with a couple of hacks that half-work, inspired in part by this StackOverflow question. But neither completely work. Here's a demo HTML with embedded code: <html><head><script> function getData() { return '<?xml version="1.0" encoding="UTF-8"?><doc>Hello</doc>'; } function dlDataURI() { window.open("data:text/xml;charset=utf-8," + getData()); } function dlWindow() { var w = window.open(); w.document.open(); w.document.write(getData()); w.document.close(); } </script><body> <div onclick="dlDataURI()">Click for Data URL</div> <div onclick="dlWindow()">Click for Window</div> </body></html> The dlDataURI() version works great in Firefox, poorly in Chrome (can't save), and not at all in IE. The Window() version works OK in Firefox and IE, and not well in Chrome (can't save, XML embedded inside HTML). Neither version ever prompts a user download, it always opens a new window trying to display the XML. Is there a good way to do what I want in client side Javascript? I'd like this to work in today's browsers, ideally Firefox, MSIE 8, and Chrome.

• Android ListView appears empty, but contains objects

  - by Lethjakman

  I'm having a really odd problem with my android listview. The listview is inside of a fragment, everything's compiling and I'm no longer getting a nullpointer error, but the listview is appearing empty. Even though it's appearing empty, the log is stating that the listview has 385 objects. I can't figure out why it's empty. I do get a blue fragment, and the listview is populated. Any ideas? How I set the adapter: ActivePackages = getList(); LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); LinearLayout mContainer = (LinearLayout) inflater.inflate(R.layout.tab_frag1_layout, null); ListView activeList = (ListView) mContainer.findViewById(R.id.activelist); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, ActivePackages); Log.i("valueof activeList",String.valueOf(activeList.getCount())); //returns 0 activeList.setAdapter(adapter); adapter.notifyDataSetChanged(); Log.i("valueof activeList",String.valueOf(activeList.getCount())); //returns 385. This is the xml for the fragment: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ListView android:id="@+id/activelist" android:layout_width="match_parent" android:layout_height="match_parent" android:background="#0073fd"> </ListView> </LinearLayout>

• Should UTF-16 be considered harmful?

  - by Artyom

  I'm going to ask what is probably quite a controversial question: "Should one of the most popular encodings, UTF-16, be considered harmful?" Why do I ask this question? How many programmers are aware of the fact that UTF-16 is actually a variable length encoding? By this I mean that there are code points that, represented as surrogate pairs, take more then one element. I know; lots of applications, frameworks and APIs use UTF-16, such as Java's String, C#'s String, Win32 APIs, Qt GUI libraries, the ICU Unicode library, etc. However, with all of that, there are lots of basic bugs in the processing of characters out of BMP (characters that should be encoded using two UTF-16 elements). For example, try to edit one of these characters: 𝄞 𝕥 𝟶 𠂊 You may miss some, depending on what fonts you have installed. These characters are all outside of the BMP (Basic Multilingual Plane). If you cannot see these characters, you can also try looking at them in the Unicode Character reference. For example, try to create file names in Windows that include these characters; try to delete these characters with a "backspace" to see how they behave in different applications that use UTF-16. I did some tests and the results are quite bad: Opera has problem with editing them Notepad can't deal with them correctly (delete for example) File names editing in Window dialogs in broken All QT3 applications can't deal with them. StackOverflow seems to remove these characters if edited directly in as Unicode characters, and only seems to allow them as HTML Unicode escapes. So... This was very simple test. Do you think that UTF-16 should be considered harmful?

• Stop UITextView from jumping when programatically setting text

  - by Michael Waterfall

  Hi there, I have to update a small amount of text in a scrolling UITextView. I'll only be inserting a character where the cursor currently is, and I'll be doing this on a press of a button on my navigation bar. My problem is that whenever I call the setText method of the text view, it jumps to the bottom of the text. I've tried using contentOffset and resetting the selectedRange but it doesn't work! Here's my example: // Remember offset and selection CGPoint contentOffset = [entryTextView contentOffset]; NSRange selectedRange = [entryTextView selectedRange]; // Update text entryTextView.text = entryTextView.text; // Try and reset offset and selection [entryTextView setContentOffset:contentOffset animated:NO]; [entryTextView setSelectedRange: selectedRange]; Is there any way you can update the text without any scroll movement at all... as if they'd just typed something on the keyboard? Many thanks, Michael Edit: I've tried using the textViewDidChange: delegate method but it's still not scrolling up to the original location. - (void)textViewDidChange:(UITextView *)textView { if (self.programChanged) { [textView setSelectedRange:self.selectedRange]; [textView setContentOffset:self.contentOffset animated:NO]; self.programChanged = NO; } } - (void)changeButtonPressed:(id)sender { // Remember position self.programChanged = YES; self.contentOffset = [entryTextView contentOffset]; self.selectedRange = [entryTextView selectedRange]; // Update text entryTextView.text = entryTextView.text; }

• C# FileStream position is off after calling ReadLine()

  - by Cristi Diaconescu

  I'm trying to read a (small-ish) file in chunks of a few lines at a time, and I need to return to the beginning of particular chunks. The problem is, after the very first call to streamReader.ReadLine(); the streamReader.BaseStream.Position property is set to the end of the file! Now I assume some caching is done in the backstage, but I was expecting this property to reflect the number of bytes that I used from that file. For instance, calling ReadLine() again will (naturally) return the next line in the file, which does not start at the position previously reported by streamReader.BaseStream.Position. My question is, how can I find the actual position where the 1st line ends, so I can return there later? I can only think of manually doing the bookkeeping, by adding the lengths of the strings returned by ReadLine(), but even here there are a couple of caveats: ReadLine() strips the new-line character(s) which may have a variable length (is is '\n' ? is it "\r\n" ? etc) I'm not sure if this would work ok with variable-length characters ...so right now it seems like my only option is to rethink how I parse the file, so I don't have to rewind. If it helps, I open my file like this: using (var reader = new StreamReader( new FileStream(m_path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))) {...} Any suggestions?

• HTTP requests and Apache modules: Creative attack vectors

  - by pinkgothic

  Slightly unorthodox question here: I'm currently trying to break an Apache with a handful of custom modules. What spawned the testing is that Apache internally forwards requests that it considers too large (e.g. 1 MB trash) to modules hooked in appropriately, forcing them to deal with the garbage data - and lack of handling in the custom modules caused Apache in its entirety to go up in flames. Ouch, ouch, ouch. That particular issue was fortunately fixed, but the question's arisen whether or not there may be other similar vulnerabilities. Right now I have a tool at my disposal that lets me send a raw HTTP request to the server (or rather, raw data through an established TCP connection that could be interpreted as an HTTP request if it followed the form of one, e.g. "GET ...") and I'm trying to come up with other ideas. (TCP-level attacks like Slowloris and Nkiller2 are not my focus at the moment.) Does anyone have a few nice ideas how to confuse the server and/or its modules to the point of self-immolation? Broken UTF-8? (Though I doubt Apache cares about encoding - I imagine it just juggles raw bytes.) Stuff that is only barely too long, followed by a 0-byte, followed by junk? et cetera I don't consider myself a very good tester (I'm doing this by necessity and lack of manpower; I unfortunately don't even have a more than basic grasp of Apache internals that would help me along), which is why I'm hoping for an insightful response or two or three. Maybe some of you have done some similar testing for your own projects? (If stackoverflow is not the right place for this question, I apologise. Not sure where else to put it.)

• How to include multiple tables programmaticaly into a Sweave document using R

  Hello, I want to have a sweave document that will include a variable number of tables in. I thought the example below would work, but it doesn't. I want to loop over the list foo and print each element as it's own table. % \documentclass[a4paper]{article} \usepackage[OT1]{fontenc} \usepackage{longtable} \usepackage{geometry} \usepackage{Sweave} \geometry{left=1.25in, right=1.25in, top=1in, bottom=1in} \listfiles \begin{document} <<label=start, echo=FALSE, include=FALSE>>= startt<-proc.time()[3] library(RODBC) library(psych) library(xtable) library(plyr) library(ggplot2) options(width=80) #Produce some example data, here I'm creating some dummy dataframes and putting them in a list foo<-list() foo[[1]]<-data.frame(GRP=c(rep("AA",10), rep("Aa",10), rep("aa",10)), X1=rnorm(30), X2=rnorm(30,5,2)) foo[[2]]<-data.frame(GRP=c(rep("BB",10), rep("bB",10), rep("BB",10)), X1=rnorm(30), X2=rnorm(30,5,2)) foo[[3]]<-data.frame(GRP=c(rep("CC",12), rep("cc",18)), X1=rnorm(30), X2=rnorm(30,5,2)) foo[[4]]<-data.frame(GRP=c(rep("DD",10), rep("Dd",10), rep("dd",10)), X1=rnorm(30), X2=rnorm(30,5,2)) @ \title{Docuemnt to test putting a variable number of tables into a sweave Document} \author{"Paul Hurley"} \maketitle \section{Text} This document was created on \today, with \Sexpr{print(version$version.string)} running on a \Sexpr{print(version$platform)} platform. It took approx \input{time} sec to process. <<label=test, echo=FALSE, results=tex>>= cat("Foo") @ that was a test, so is this <<label=table1test, echo=FALSE, results=tex>>= print(xtable(foo[[1]])) @ \newpage \subsection{Tables} <<label=Tables, echo=FALSE, results=tex>>= for(i in seq(foo)){ cat("\n") cat(paste("Table_",i,sep="")) cat("\n") print(xtable(foo[[i]])) cat("\n") } #cat("<<label=endofTables>>= ") @ <<label=bye, include=FALSE, echo=FALSE>>= endt<-proc.time()[3] elapsedtime<-as.numeric(endt-startt) @ <<label=elapsed, include=FALSE, echo=FALSE>>= fileConn<-file("time.tex", "wt") writeLines(as.character(elapsedtime), fileConn) close(fileConn) @ \end{document} Here, the table1test chunk works as expected, and produced a table based on the dataframe in foo[[1]], however the loop only produces Table(underscore)1.... Any ideas what I'm doing wrong ?
