• How to create empty folders with maven archetype?

  - by chrsk

  There is an existing issue for this approach, located on Codehaus JIRA #ARCHETYPE-57, but all instructions listed in this ticket failed for me. Also the blog post of marekdec How to get maven archetype to generate empty directories fails for me. The trick within the archetype.xml with the trailing / doesnt works for me: <resources> <resource>src/main/webapp/</resource> Unable to find resource 'archetype-resources/src/main/webapp/' Also the fileSet directory in archetype-metadata.xml does not work for me: <fileSet filtered="true" encoding="UTF-8"> <directory>src/main/webapp/</directory> </fileSet> Is there any other solution? Or did i miss something? Thanks

• Use of serialization in JMX calls on Websphere Appserver to avoid ClasscastException

  - by hstoerr

  We are using JMX for communication between different EARs on the same Websphere application server (6.1). All works well if we only use Java types as arguments, but if we use or own the problem is that we get ClassCastExceptions on the receiver side. This is obviously a classloader problem: if the jar with the argument types is put into the JRE endorsed directory, such that all classloaders use exactly the same class, the Exception disappear. But we would much prefer to put the library that defines the argument types in the EAR itself. Now my question: is there a trick to persuade WAS to serialize and deserialize the arguments during the JMX call? I guess in this case the ClassCastException would dissappear.

• Given a string describing a Javascript function. convert it to a Javascript function

  - by brainjam

  Say I've got a Javascript string like the following var fnStr = "function(){blah1;blah2;blah3; }" ; (This may be from an expression the user has typed in, duly sanitized, or it may be the result of some symbolic computation. It really doesn't matter). I want to define fn as if the following line was in my code: var fn = function(){blah1;blah2;blah3; } ; How do I do that? The best I've come up with is the following: var fn = eval("var f = function(){ return "+fnStr+";}; f() ;") ; This seems to do the trick, even though it uses the dreaded eval(), and uses a slightly convoluted argument. Can I do better? I.e. either not use eval(), or supply it with a simpler argument?

• Videoconference using Flash and SIP

  - by Júlio Santos

  The front-end will be Flash, to run in a browser and have access to the camera. I must use SIP to control the sessions. How could I do this? Will a Red5 server and a MjSip sever do the trick? As in i'd use MjSip to setup the session and warn users about calls, and Red5 to stream the video and audio? Any suggestions? Note: only 1-on-1 conference is required.

• Compare two String with MySQL

  - by Scorpi0

  Hi, I wan't to compare two strings in a SQL request so I can retrieve the best match, the aim is to propose to an operator the best zip code possible. For example, in France, we have Integer Zip code, so I made an easy request : SELECT * FROM myTable ORDER BY abs(zip_code - 75000) This request returns first the data closest of Paris. Unfortunatelly, United Kingdom have zip code like AB421RS, so my request can't do it. I see in SQL Server a function 'Difference' : http://www.java2s.com/Code/SQLServer/String-Functions/DIFFERENCEworkoutwhenonestringsoundssimilartoanotherstring.htm But I use MySQL.. Is there anyone who have a good idea to do the trick in one simple request ? PS : the Levenshtein Distance will not do it, as I really wan't to compare string like if they were number. ABCDEF have to be closer to AWXYZ than to ZBCDEF.

• Retrieve input and output parameters for SQL stored procs and functions?

  - by Darth Continent

  For a given SQL stored proc or function, I'm trying to obtain its input and output parameters, where applicable, in a Winforms app I'm creating to browse objects and display their parameters and other attributes. So far I've discovered the SQL system function object_definition, which takes a given sysobjects.id and returns the text of that object; also discovered via search this post which describes extracting the parameters in the context of a app using the ADO.NET method DeriveParameters in conjunction with some caching for better performance; and for good measure found some helpful system stored procs from this earlier post on Hidden Features of SQL Server. I'm leaning towards implementing the DeriveParameters method in my C# app, since parsing the output of object_definition seems messy, and I haven't found a hidden feature in that post so far that would do the trick. Is DeriveParameters applicable to both functions and stored procs for purposes of retreiving their parameters, and if so, could someone please provide an example?

• Faster projected-norm (quadratic-form, metric-matrix...) style computations

  - by thekindamzkyoulike

  I need to perform lots of evaluations of the form X(:,i)' * A * X(:,i) i = 1...n where X(:,i) is a vector and A is a symmetric matrix. Ostensibly, I can either do this in a loop for i=1:n z(i) = X(:,i)' * A * X(:,i) end which is slow, or vectorise it as z = diag(X' * A * X) which wastes RAM unacceptably when X has a lot of columns. Currently I am compromising on Y = A * X for i=1:n z(i) = Y(:,i)' * X(:,i) end which is a little faster/lighter but still seems unsatisfactory. I was hoping there might be some matlab/scilab idiom or trick to achieve this result more efficiently?

• What's the cleanest way to programmatically kill and restart explorer.exe?

  - by Paul Accisano

  Greetings all, I'm working on a Windows program whose installation necessitates restarting explorer.exe. I know "Reboot your computer to complete the installation" is the standard method here, but I'd like my installer to give users the option of just restarting Explorer so they can start using my program immediately. What's the best way to do that? Of course I could just find and kill the process, but that seems rather icky. Is there some trick to, say, make Explorer think the user is logging off and close cleanly? Thanks!

• Is there a better way of designing zend_forms rather than using decorators?

  - by Hanseh

  Hi, I am currently using zend_decorators to add styles to my form. I was wondering if there is an alternative way of doing it? It is a bit difficult to write decorators. I would love the casual one using divs and css style : <input type="submit" class="colorfulButton" > It is much simpler rather than set a decorator for a certain control and add it. Since it requires creating a decorator for each style implementation and adding it up with the control. Will view helpers to the trick?

• Dice face value recognition

  - by Jakob Gade

  I’m trying to build a simple application that will recognize the values of two 6-sided dice. I’m looking for some general pointers, or maybe even an open source project. The two dice will be black and white, with white and black pips respectively. Their distance to the camera will always be the same, but their position on the playing surface will be random. (not the best example, the surface will be a different color and the shadows will be gone) I have no prior experience with developing this kind of recognition software, but I would assume the trick is to first isolate the faces by searching for the square profile with a dominating white or black color (the rest of the image, i.e. the table/playing surface, will in distinctly different colors), and then isolate the pips for the count. Shadows will be eliminated by top down lighting. I’m hoping the described scenario is so simple (read: common) it may even be used as an “introductory exercise” for developers working on OCR technologies or similar computer vision challenges.

• hidden row causing issue with tablesorter zebra striping

  - by Harvengure

  Sorry if this has already been solved elsewhere but my searches have been able to turn up nothing and my attempts at solving the issue myself have made even less progress. :P Put quite simply I have a table that is using the jquery tablesorter and it's zebra widget. In this table there is a hidden column. I've so far been able to make it so that when a tr contains specific text (I was aiming for * but was seemingly unable to get \* to work for whatever reason...and I suspect my selector is perhaps not specific enough) the containing row is set not to display by ".hide()". The problem I am having though is when the row is hidden, tablesorter does exactly what it should do and stripes all the rows their specific colours based on their odd and even values. Of course .remove doesn't do the trick either as the table still sees some funny striping. Any thoughts on how to make it so that when a row is hidden, the striping compensates?

• Run Python CGI Script on Windows XP

  - by daveywc

  I have a Windows XP machine that has Apache installed via a VisualSVNServer installation. I am . trying to get a simple python cgi script to run in my browser e.g. http://build.procepts.com.au:8080/hg/cgi-bin/test.cgi. However despite trying all the recommended approaches the browser only ever displays the plain text from the cgi script. Amongst many other attempted solutions I have followed the instructions contained here. My ultimate aim is to be able to use the Apache web server to serve repositories from a new Mercurial installation. Seeing as Apache is already installed from VisualSVNServer I thought I might as well make use of it. Is there some other trick to get this working?

• How to trigger saved password autofill in browsers?

  - by Aleksander Kmetec

  I have a web application written in pure JavaScript (no pre-generated HTML except for the document which loads all the JS files). This app contains a login form which is created dynamically when the document.ready event event is triggered. I trick the browser into displaying the "Remember password?" dialog by posting the login form into a hidden iframe before logging in using ajax (in Firefox the password appears on the saved password list, so this part obviously works) but saved passwords never get filled in after the login screen is loaded again at a later time. The same thing happens in Firefox and Safari. Is there something I can do or some function I can call to trigger autofill? UPDATE: autofill works in Safari on initial page load, but not when user logs out and the login form is recreated without a page reload. In Firefox it never works.

• emacs: force ido-mode to forget history...

  - by Stephen

  Hi, I wonder if I can keep ido from not remembering my history and only show completions for files that are in the current directory when I am searching for a file. I understand that this history feature is useful at times, but I often end up editing the incorrect file because I think I am editing file called 'abc.txt' in the current directory but in fact I am editing the file by the same name in another one that I previously visited (often happens when there is not an 'abc.txt' in the current directory, as I mistakenly assume). From reading the ido.el file I thought to set in my .emacs file (also evaluated these expressions in running emacs instance): (custom-set-variables '(ido-enable-last-directory-history nil) '(ido-record-commands nil) ) and deleted a file called .ido.last in ~/, but still it remembers some previous files I've visited before making these changes. How can I purge my previous history, and I am not entirely sure what the difference between the two variables above are but seems to have done the trick to keep ido from remembering files I visit in the future? Thanks for your help!

• Set an Interface Builder created element's state programatically

  - by mvexel

  I have a couple of UISwitch elements in a view controller that is presented modally in my iPhone app. I set up the view in IB. I want these UISwitch elements to reflect the current values in my [NSUserDefaults standardUserDefaults] where I store the appropriate BOOLs. I thought this would do the trick setting the switches to the right state, but no: -(void)viewWillAppear:(BOOL)animated { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [backgroundSwitch setOn:[defaults boolForKey:kTrackInBackgroundKey] animated:NO]; [batterySaveSwitch setOn:[defaults boolForKey:kBatterySaveKey] animated:NO]; } The backgroundSwitch and batterySaveSwitch are declared as properties for the view controller class. They are not initialized; that does not seem to make a difference. I did check the values coming out of the NSUserDefaults dictionary. The method is being called at the right time.

• SQL to retrieve the latest records, grouping by unique foreign keys

  - by jbox

  I'm creating query to retrieve the latest posts in a forum using a SQL DB. I've got a table called "Post". Each post has a foreign key relation to a "Thread" and a "User" as well as a creation date. The trick is I don't want to show two posts by the same user or two posts in the same thread. Is it possible to create a query that contains all this logic? # Grab the last 10 posts. SELECT id, user_id, thread_id FROM posts ORDER BY created_at DESC LIMIT 10; # Grab the last 10 posts, max one post per user SELECT id, user_id, thread_id FROM post GROUP BY user_id ORDER BY date DESC LIMIT 10; # Grab the last 10 posts, max one post per user, max one post per thread???

• Alternative to DITA Open Toolkit

  - by Adam

  I'm working on a web app that will need to process DITA documents from persistent storage (likely a JCR). The DITA Open Toolkit is the only DITA implementation I'm aware of, but it requires all of your documents to exist on the filesystem. Ideally, I'd like something that works like the DITA OT, but allows you to provide a resolver (much like an XSLT URIResolver) to pull referenced content from other sources. If people have other ideas, such as using a virtual filesystem to trick the DITA OT into working, I'd love to hear those too. Thanks!

• Find the minimum gap between two numbers in an AVL tree

  - by user1656647

  I have a data structures homework, that in addition to the regular AVL tree functions, I have to add a function that returns the minimum gap between any two numbers in the AVL tree (the nodes in the AVL actually represent numbers.) Lets say we have the numbers (as nodes) 1 5 12 20 23 21 in the AVL tree, the function should return the minimum gap between any two numbers. In this situation it should return "1" which is |20-21| or |21-20|. It should be done in O(1). Tried to think alot about it, and I know there is a trick but just couldn't find it, I have spent hours on this. There was another task which is to find the maximum gap, which is easy, it is the difference between the minimal and maximal number.

• wheel of fortune collision detection

  - by Andrew

  Hey, I have a wheel segmented into 8 pie pieces, and a picker that is pointing at the currently selected segment (think wheel of fortune). I want to highlight the currently selected segment, and so have started to use Chipmunk to construct the 8 segments, attached to a rotating body, and then the picker that is put in a position to collide with each of the segments. The trick is, how do you allow the picker to pass over top of the segments, while still getting the collision, but not actually colliding and slowing down the wheel? I haven't started down this path yet, but thought this may solve the problem: removing the colliding segment and then putting it back after the picker has started colliding with another segment a bit away (like two segments away). There may be a much simpler solution not even involving Chipmunk that I haven't thought of. Thanks, Andrew

• Winforms - Visually remove button click event

  - by Wayne Koorts

  .NET newbie alert Using Visual C# 2008 Express Edition I have accidentally created a click event for a button. I then deleted the automatically-created method code, which resulted in an error saying that the function, which had now been referenced in the form loading code, could no longer be found. Deleting the following line from the Form1.Designer.cs file's InitializeComponent() function... this.btnCopy.Click += new System.EventHandler(this.btnCopy_Click); ... seems to do the trick, however, it makes me feel very dirty because of the following warning at the beginning of the #region: /// Required method for Designer support - do not modify /// the contents of this method with the code editor. I haven't been able to find a way to do this using the form designer, which I assume is the means implied by this warning. What is the correct way to do this?

• MySQLdb through proxy

  - by MihaiD

  I'm using the above mentioned Python lib to connect to a MySQL server. So far I've worked locally and all worked fine, until i realized I'll have to use my program in a network where all access goes through a proxy. Does anyone now how I can set the connections managed by that lib to use a proxy? Alternatively: do you know of another Python lib for MySQL that can handle this? I also have no idea if the if the proxy server will allow access to the standard MySQL port or how I can trick it to allow it. Help on this is also welcomed.

• SetTimeout() and ClearTimeout() to stop freezing of IE8 and dialog aobut scripts overruning

  - by igl00

  I have some 3rd party software where i can open nsites and run javascript. Because some sites make me stack overflow i ussed the trick wih Registry to modify Styles WRAD to FFFFFF. Still some sites may do stack overflow due to DOM. I thought on start of running each site i would do javascript: setTimeout("window.status='one';",10000); then on then end i would like to clear it - my question is how to if this doesnt have any actual id? Will the usual clearTimeout() without anything inside do it fine?

• Javascript: Pass array as optional method args

  - by Dave Paroulek

  console.log takes a string and replaces tokens with values, for example: console.log("My name is %s, and I like %", 'Dave', 'Javascript') would print: My name is Dave, and I like Javascript I'd like to wrap this inside a method like so: function log(msg, values) { if(config.log == true){ console.log(msg, values); } } The 'values' arg might be a single value or several optional args. How can I accomplish this? If I call it like so: log("My name is %s, and I like %s", "Dave", "Javascript"); I get this (it doesn't recognize "Javascript" as a 3rd argument): My name is Dave, and I like %s If I call this: log("My name is %s, and I like %s", ["Dave", "Javascript"]); then it treats the second arg as an array (it doesn't expand to multiple args). What trick am I missing to get it to expand the optional args?

• Pass elements of a list as arguments to a function in python

  - by Wilduck

  I'm building a simple interpreter in python and I'm having trouble handling differing numbers of arguments to my functions. My current method is to get a list of the commands/arguments as follows. args = str(raw_input('>> ')).split() com = args.pop(0) Then to execute com, I check to see if it is in my dictionary of command- code mappings and if it is I call the function I have stored there. For a command with no arguments, this would look like: commands[com]() However, if a command had multiple arguments, I would want this: commands[com](args[0],args[1]) Is there some trick where I could pass some (or all) of the elements of my arg list to the function that I'm trying to call? Or is there a better way of implementing this without having to use python's cmd class?
