• Velocity templates seem to fail with UTF-8

  - by steve

  Hi, i have been trying to use a velocity Template with the following content: Sübjäct $item everything works fine except the translation of the tow unicode characters. The result string printed on the commandline looks like: Sübjäct foo I searched the velocity website and the web an this issue, and came uo with differnt font encoding options, which i added to my code. But those won't help. This is the actuall code: velocity.setProperty("file.resource.loader.path", absPath); velocity.setProperty("input.encoding", "UTF-8"); velocity.setProperty("output.encoding", "UTF-8"); Template t = velocity.getTemplate("subject.vm"); t.setEncoding("UTF-8"); StringWriter sw = new StringWriter(); t.merge(null, sw); System.out.println(sw.getBuffer()); Can anyone give me some hints, how to fix this issue?

• How can I rewrite Verilog code to remove extra reg?

  - by EquinoX

  How can I rewrite the code below so that I don't need to have an extra reg mul. I just wanted to take the 32 bits of the resulting 32 * 32 bit multiplication and put it into Result input signed[31:0] Reg1; input signed[31:0] Reg2; output[31:0] Result; reg signed[31:0] Result; reg[63:0] mul; mul = Reg1 * Reg2; Result = mul[31:0];

• Caching result of SELECT statement for reuse in multiple queries

  - by Andrew

  I have a reasonably complex query to extract the Id field of the results I am interested in based on parameters entered by the user. After extracting the relevant Ids I am using the resulting set of Ids several times, in separate queries, to extract the actual output record sets I want (by joining to other tables, using aggregate functions, etc). I would like to avoid running the initial query separately for every set of results I want to return. I imagine my situation is a common pattern so I am interested in what the best approach is. The database is in MS SQL Server and I am using .NET 3.5.

• HTML, jQuery Suggestion for a List

  - by AnApprentice

  Hello, I'm creating an app that will have a list of messages, each message can be either read or unread. Think GMAIL (though I'm not trying to rebuild that)... My question is when I output all these messages, I need to list if the message is read or unread, I also need to provide the ability to change the message status, from read to unread. That being said, how do you suggest I stored this? A checkbox, a hidden input value? Any thoughts? Thanks

• Hibernate - join un related objects

  - by CuriousMind

  I have a requirement, wherein I have to join two unrelated objects using Hibernate HQL. Here is the sample POJO class class Product{ int product_id; String name; String description; } and Class Item{ int item_id; String name; String description; int quantity; int product_id; //Note that there is no composed product object. } Now I want to perform a query like select * from Product p left outer join Item i on p.product_id = i.item_id I want a multidimensional array as an output of this query so that I can have separate instances of Product and Item, instead of one composed in another. Is there any way to do this in Hibernate?

• Java Servlet framework that does things like rencoding images to preferred format etc.

  - by mP

  Are there any frameworks/libraries that provide servlets/filters etc that handle reencoding on the fly of images. interpret the accept headers and output the file, reencoding into the new format if necessary by checking the actual format of the original image file. provide a low and high quality version of an image. re encode an image into new dimensions. width and height parameters might query string parameters. I could create versions of the file in all the formats, at upload time but the seems overkill. I would rather lazily create the rencoded file and stick it in a cache if it gets served again etc.

• Java splitting string by custom regex match

  - by slikz

  I am completely new to regular expressions so I'm looking for a bit of help here. I am compiling under JDK 1.5 Take this line as an example that I read from standard input: ab:Some string po:bubblegum What I would like to do is split by the two characters and colon. That is, once the line is split and put into a string array, these should be the terms: ab:Some string po:bubblegum I have this regex right now: String[] split = input.split("[..:]"); This splits at the semicolon; what I would like is for it to match two characters and a semicolon, but split at the space before that starts. Is this even possible? Here is the output from the string array: ab Some String po bubblegum I've read about Pattern.compile() as well. Is this something I should be considering?

• Visual Studio 2010 Macro - Reporting Progress

  - by user295841

  I have just discovered macros in Visual Studio and I can't be happier. Well... I have my complaints but... you know ;) A few of my macros are taking quite a while to complete and I am looking for a way to track progress. I build a log file during most of my macro processes but I have not found a good way to report progress without pausing the process. Ex. MsgBox("Progress") Any way to access the output window or even better the VS status bar?

• Is there a way to shift the equation numbering one tab space from the right margin (shift towards le

  - by Murari

  I have been formatting my dissertation and one little problem is stucking me up. I used the following code to typeset an equation \begin{align} & R=\frac{P^2}{P+S'} \label{eqn:SCS}\\ &\mbox {where} \quad \mbox R = \mbox {Watershed Runoff} \notag\\ &\hspace{0.63in} \mbox P = \mbox{Rainfall} \notag\\ &\hspace{0.63in} \mbox S' = \mbox{Storage in the watershed $=\frac{1000}{CN}-10$ }\notag \end{align} My output requirement is such that: The equation should begin one tab space from the left margin The equation number should end at one tab space from the right margin With the above code, I have the equation begin at the right place but not the numbering. Any help will be extremely appreciated. Thanks MP

• Library for Dataflow in C

  - by msutherl

  How can I do dataflow (pipes and filters, stream processing, flow based) in C? And not with UNIX pipes. I recently came across stream.py. Streams are iterables with a pipelining mechanism to enable data-flow programming and easy parallelization. The idea is to take the output of a function that turns an iterable into another iterable and plug that as the input of another such function. While you can already do this using function composition, this package provides an elegant notation for it by overloading the operator. I would like to duplicate a simple version of this kind of functionality in C. I particularly like the overloading of the operator to avoid function composition mess. Wikipedia points to this hint from a Usenet post in 1990. Why C? Because I would like to be able to do this on microcontrollers and in C extensions for other high level languages (Max, Pd*, Python). * (ironic given that Max and Pd were written, in C, specifically for this purpose – I'm looking for something barebones)

• Rails 3 respond_with, route constraints and resources

  - by Intelekshual

  I'm building a versioned API, so I have the following nested controllers: ApiController < ApplicationController Api::V1Controller < ApiController Api::V1::EventsController < Api::V1Controller The API is accessed via a subdomain. I have the following routes: constraints(:subdomain => "api") do scope :module => 'api' do namespace :v1 do resources :events end end end This produces the type of URL I want (/v1/events). The problem I'm facing is when using responds_with in Api::V1::EventsController. Just doing something as simple as the below fails with the error too few arguments: def index @events = Event.all respond_with(@events) end I know respond_width is meant to be used with resources, but I'm not sure how the events resource should be accessed from the constrained, scoped, and namespaced route. I can output other things (such as current_user), just not an array of events. Help?

• Does this have anything to do with endian-ness?

  - by eSKay

  This piece of code: #include<stdio.h> void hello() { printf("hello\n"); } void bye() { printf("bye\n"); } int main() { printf("%p\n", hello); printf("%p\n", bye); return 0; } output on my machine: 0x80483f4 0x8048408 [second address is bigger in value] on Codepad 0x8048541 0x8048511 [second address is smaller in value] Does this have anything to do with endian-ness of the machines? If not, Why the difference in the ordering of the addresses? Also, Why the difference in the difference? 0x8048541 - 0x8048511 = 0x30 0x8048408 - 0x80483f4 = 0x14 Btw, I just checked. This code (taken from here) says that both the machines are Little-Endian #include<stdio.h> int main() { int num = 1; if(*(char *)&num == 1) printf("Little-Endian\n"); else printf("Big-Endian\n"); return 0; }

• How to update a library in my application

  - by andho

  I have used a library like ZendFramework in my project which I have put in Subversion. Now I want to update the version that I have put in Subversion. What's the best way to do this? Copying, taking a svn diff and patching the working copy or just copying the new files over the old files? I have tried svn diff with svn diff but this doesn't output anything. Normal diff outputs some stuff but it also considers the .svn directories.

• Custom events and event pooling in jQuery - What's the point?

  - by Nick Lowman

  I've been reading about custom events in jQuery and why they should be used but I'm still clearly missing the point. There is a very good article I read here that has the following code example; function UpdateOutput() { var name = $('#txtName').val(); var address = $('#txtAddress').val(); var city = $('#txtCity').val(); $('#output').html(name + ' ' + address + ' ' + city); } $(document).bind('NAME_CHANGE ADDRESS_CHANGE CITY_CHANGE', function() { UpdateOutput(); }); $('#txtAddress').keyup(function() { $(document).trigger('ADDRESS_CHANGE'); }); $('#txtCity').keyup(function() { $(document).trigger('CITY_CHANGE'); }); Can someone tell me why I just don't call the UpdateOutput() function directly? It would still work exactly the same way, i.e. $('#txtAddress').keyup(function() { UpdateOutput() }); $('#txtCity').keyup(function() { UpdateOutput() }); Many thanks

  I am trying to write a C++ program, but I am not familiar with C++. I have a .txt file, which contains values as follows: 0 0.0146484 0.0292969 0.0439453 0.0585938 0.0732422 0.0878906 What I have done in my C++ code is as follows: #include <iostream> #include <fstream> using namespace std; int main() { string line; ifstream myReadFile; myReadFile.open("Qi.txt"); if(myReadFile.is_open()) { while(myReadFile.good()) { getline(myReadFile,line); cout << line << endl; } myReadFile.close(); } return 0; } I would like to make the output of the program an array, i.e. line[0] = 0 line[1] = 0.0146484 line[2] = 0.0292969 line[3] = 0.0439453 line[4] = 0.0585938 line[5] = 0.0732422 line[6] = 0.0878906

• How can i initialize an array without knowing it size?

  - by Sara

  I have a situation where i have to apply a criteria on an input array and reuturn another array as output which will have smaller size based upon the filtering criteria. Now problem is i do not know the size of filtered results, so i can not initialize the array with specific value. And i do not want it to be large size will null values because i am using array.length; later on. One way is to first loop the original input array and set a counter, and then make another loop with that counter length and initialize and fill this array[]. But is there anyway to do the job in just one loop?

• Stopping and Starting Apache Using PHP (!)

  - by Abs

  Hello all, I have two problems which are related. 1) I have a batch file that contains this: net stop wampapache net start wampapache Which tries to stop and start my wamp server. When I double click the stop.bat file with the above it works successfully. When I try to run that from my PHP script, it stops the server but doesn't start it fully which I am guessing is because Apache is waiting for that PHP process to exit? function php_kill(){ exec('stop.bat', $output = array(), $return); return $return; } 2) Is there a way to restart my webserver (apache) whilst keeping session variables that PHP needs available? Thanks all

• Use a cat + grep as an included source in bash

  - by Andrew

  I'm on a shared webhost where I don't have permission to edit the global bash configuration file at /ect/bashrc. Unfortunately there is one line in the global file, mesg y, which puts the terminal in tty mode and makes scp and similar commands unavailable. My local ~./bashrc includes the global file as a source, like so: # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi My current workaround uses cat and grep to output the global file, sans offending line, into a local file and use that as a source. # Source global definitions if [ -f /etc/bashrc ]; then cat /etc/bashrc | grep -v mesg > ~/.bash_global . ~/.bash_global fi Is there a way to do include a grokked file like this without the intermediate step of creating an actual file? Something like this? . cat /etc/bashrc | grep -v mesg > ~/.bash_global

• Will an optimizing compiler remove calls to a method whose result will be multiplied by zero?

  - by Tim R.

  Suppose you have a computationally expensive method, Compute(p), which returns some float, and another method, Falloff(p), which returns another float from zero to one. If you compute Falloff(p) * Compute(p), will Compute(p) still run when Falloff(p) returns zero? Or would you need to write a special case to prevent Compute(p) from running unnecessarily? Theoretically, an optimizing compiler could determine that omitting Compute when Falloff returns zero would have no effect on the program. However, this is kind of hard to test, since if you have Compute output some debug data to determine whether it is running, the compiler would know not to omit it because of that debug info, resulting in sort of a Schrodinger's cat situation. I know the safe solution to this problem is just to add the special case, but I'm just curious.

• How do I implement an higher lower game algorithm?

  - by lazorde

  The computer will guess a player’s number between 1 and 100. After each guess the human player should respond “higher”, “lower” or “correct”. Your program should be able to guess the player’s number in no more than 7 tries. Begin by explaining the game to the player, telling him/her to think of a number between 1 and 100. Make the computer do what you would normally do to guess a number in a certain range. Allow the user to respond with “higher”, “lower”, or “correct” after each computer guess. Output the number of tries it took the computer to guess the number. Make the game as user friendly as you can.

• Why isn't the copy constructor elided here?

  - by Jesse Beder

  (I'm using gcc with -O2.) This seems like a straightforward opportunity to elide the copy constructor, since there are no side-effects to accessing the value of a field in a bar's copy of a foo; but the copy constructor is called, since I get the output meep meep!. #include <iostream> struct foo { foo(): a(5) { } foo(const foo& f): a(f.a) { std::cout << "meep meep!\n"; } int a; }; struct bar { foo F() const { return f; } foo f; }; int main() { bar b; int a = b.F().a; return 0; }
