• What does a well formed XML or Schema look like for InfoPath form creation?

  - by Keith Sirmons

  Howdy, Are there any resources out there that defines how a well formed XML or Schema may look like for InfoPath? When designing a new form, there is an option to base the new form off of an existing XML document or XML Schema as the data source. I am looking for any guidelines or rules that will help me make sure the structure of the XML file I use to create the form will work the best it could work. I am creating the XML structure for another project, but we want to make sure the XML that is created would be InfoPath friendly for possible future applications. Thank you, Keith

• When functionalities of html attributes and css styles overlap

  - by AspOnMyNet

  1) If inside CSS file we specify the following style: .td { text-align:center; } While in a Html file we have <td align=”right” … > then value set in CSS file will take precedence over an inline html attribute and thus elements contained inside <td> cell will be aligned to the center. a) Is same true for all html attributes? Meaning if a CSS rule and an html attribute functionalities overlap , will the CSS rule always take precedence? BTW – I know we should usually prefer using CSS rules vs html attributes thanx

• How to write a linter?

  - by jbdavid

  In my day job I, and others on my team write a lot of hardware models in Verilog-AMS, a language supported primarily by commercial vendors and a few opensource simulator projects. One thing that would make supporting each others code more helpful would be a LINTER that would check our code for common problems and assist with enforcing a shared code formatting style. I of course want to be able to add my own rules and, after I prove their utility to myself, promote them to the rest of the team.. I don't mind doing the work that has to be done, but of course also want to leverage the work of other existing projects. Does having the allowed language syntax in a yacc or bison format give me a leg up? or should I just suck each language statement into a perl string, and use pattern matching to find the things I don't like? (most syntax and compilation errors are easily caught by the commercial tools.. but we have some of our own extentions.)

• Rewrite URL with .htaccess

  - by Joaquin McCoy

  Hi guys, I've this url: http://www.test.com/page.php?k=m1ns and I want this one: http://www.test.com/r/m1ns My .htaccess: Options +FollowSymlinks RewriteEngine on RewriteBase / RewriteRule ^k/([^/\.]+)/?$ page.php?k=$1 [L] # force www. in all requests RewriteCond %{HTTP_HOST} ^test\.com [NC] RewriteRule ^(.*)$ http://www.test.com/$1 [L,R=301] # enable hiding php extension RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^(.*)$ $1.php But it doesn't work. Only the non-www - www and hiding php rules works. If I put http://www.test.com/page.php?k=m1ns does not rewrite. Anyone knows why? Thanks.

• Prolog Program for a recordings database

  - by RP

  I have three types of facts: album(code, artist, title, date). songs(code, songlist). musicians(code, list). Example: album(123, 'Rolling Stones', 'Beggars Banquet', 1968). songs(123, ['Sympathy for the Devil', 'Street Fighting Man']). musicians(123, [[vocals, 'Mick Jagger'], [guitar, 'Keith Richards', 'Brian Jones']]. I need to create these 4 rules: together(X,Y) This succeeds if X and Y have played on the same album. artistchain(X,Y) This succeeds if a chain of albums exists from X to Y; two musicians are linked in the chain by 'together'. role(X,Y) This succeeds if X had role Y (e.g. guitar) ever. song(X,Y) This succeeds if artist X recorded song Y. Any help?

• Css editor with certain features

  - by user255408

  I need a light css editor with certain functions. Already downloaded and tried a few apps but still no luck, none of them fit my requirements. Actually, there is one, CssEdit (or TextMate), but unfortunately i'm a windows user... Already tried: built-in NetBeans IDE css editor (btw nice editor, the one i'm using now for css) IntelJ IDE (very good html and css editor, but using the entire ide just for this - that's crazy) ArduoCss (very buggy in win7 environment) Notepad Notepad++ (it rules, but as i said, i need something more functional for css editing) Style Master ( if i don't find anything else, probably i'll choose this one) Stylizer ( also might be my choice, but it's black interface kills me, also extremy noob-oriented, i even couldn't find a way to see the source code) Some of the features i am looking for: grouping by comments like here snippets autocomplete, if i type for instance f-s, it should recognize and expand it to "font-size" property color picker The editor must have at least the first feature that i listed above. Sorry for my poor english.

• Custom StyleCop rule not working as expected

  - by Jon

  I'm trying to write a StyleCop rule that disallows underscores anywhere. There is a rule to say that you cant have public string _myfield but I don't want underscores anywhere ie/method names, property names, method parameters. Below is my code but its not working properly. Can anyone suggest why? using Microsoft.StyleCop; using Microsoft.StyleCop.CSharp; namespace DotNetExtensions.StyleCop.Rules { [SourceAnalyzer(typeof(CsParser))] public class NoUnderScores : SourceAnalyzer { public override void AnalyzeDocument(CodeDocument document) { CsDocument csdocument = (CsDocument) document; if (csdocument.RootElement != null && !csdocument.RootElement.Generated) csdocument.WalkDocument(new CodeWalkerElementVisitor<object>(this.VisitElement), null, null); } private bool VisitElement(CsElement element, CsElement parentElement, object context) { if (!element.Generated) { foreach(var token in element.Tokens) { if (token.Text.Contains("_")) AddViolation(element, "NoUnderScores"); } } return true; } } }

• Neural Network problems

  - by Betamoo

  I am using an external library for Artificial Neural Networks in my project.. While testing the ANN, It gave me output of all NaN (not a number in C#) The ANN has 8 input , 5 hidden , 5 hidden , 2 output, and all activation layers are of Linear type , and it uses back-propagation, with learning rate 0.65 I used one testcase for training { -2.2, 1.3, 0.4, 0.5, 0.1, 5, 3, -5 } ,{ -0.3, 0.2 } for 1000 epoch And I tested it on { 0.2, -0.2, 5.3, 0.4, 0.5, 0, 35, 0.0 } which gave { NaN , NaN} Note: this is one example of many that produces same case... I am trying to discover whether it is a bug in the library, or an illogical configuration.. The reasons I could think of for illogical configuration: All layers should not be linear Can not have descending size layers, i.e 8-5-5-2 is bad.. Only one testcase ? Values must be in range [0,1] or [-1,1] Is any of the above reasons could be the cause of error, or there are some constraints/rules that I do not know in ANN designing..? Note: I am newbie in ANN

• Why friend overloaded operator is preferred to conversion operator in this case

  - by skydoor

  Hi I have a code like this, I think both the friend overloaded operator and conversion operator have the similar function. However, why does the friend overloaded operator is called in this case? What's the rules? Thanks so much! class A{ double i; public: A(int i):i(i) {} operator double () const { cout<<"conversion operator"<<endl;return i;} // a conversion operator friend bool operator>(int i, A a); // a friend funcion of operator > }; bool operator>(int i, A a ){ cout<<"Friend"<<endl; return i>a.i; } int main() { A aa(1); if (0 > aa){ return 1; } }

• Aborting jQuery().load()

  - by Daniel I-S

  The .load() function of the jQuery library allows you to selectively load elements from another page (subject to certain rules). I would like to know whether it is possible to abort the load process. In our application, a user can browse a list of items. They may choose to click a button which loads and displays additional information about an item from another document (which can take some time). If they choose a different item in the list whilst a .load() is still happening, I would like the loading to be aborted. Is this possible? Is it even worth it? Any ideas? Dan

• UIView Subview Does not autoresize on orientation change

  - by Jason

  In my iPhone app, I have a view controller with two views (essentially, a front & back view). The front view is the main UIView, and the back view is a secondary UIView which is added as a subview using [self.view addSubview:backView] when showing the back and [backView removeFromSuperview] when hiding it. However, when the orientation changes, I have the following issue: the main UIView (frontView) rotates & all of its elements resize properly, but the secondary/subview UIView (backView) does not rotate & all of its elements do not resize properly. Does anyone have suggestions on how to make the secondary UIView autoresize properly according to the rules I have set in Interface Builder?

• Shorten Zend Framework Route Definitions

  - by Sebastian Hoitz

  Hi! How can I shorten the definition of my custom routes in Zend Framework? I currently have this as definition: $route = new Zend_Controller_Router_Route( ":module/:id", array( "controller" => "index", "action" => "index" ), array("id" => "\d+") ); self::$frontController->getRouter()->addRoute('shortcutOne', $route); $route = new Zend_Controller_Router_Route( ":module/:controller/:id", array("action" => "index"), array("id" => "\d+") ); self::$frontController->getRouter()->addRoute('shortcutTwo', $route); $route = new Zend_Controller_Router_Route( ":module/:controller/:action/:id", null, array("id" => "\d+") ); self::$frontController->getRouter()->addRoute('shortcutThree', $route); Is there a way to better combine these rules? And what are your best practices in where to place these? I currently have them in my bootstrap class right after the Front Controller initialization.

• bash tips needed for understanding how to escape characters in command-line

  - by Jesper Rønn-Jensen

  My knowledge of commandline bash is missing on a particular area: I constantly forget how to properly escape characters. Today I wanted to echo this string into a file: #!/bin/env bash python -m SimpleHTTPServer echo "#!/bin/env bash\npython -m SimpleHTTPServer" server.sh && chmod +x server.sh -bash: !/bin/env: event not found That's right: Remember to escape ! or bash will think it's a special bash event command. But I can't get the escaping right! \! yields \! in the echoed string, and so does \\!. Furthermore, \n will not translate to a line break. Do you have some general tips that makes it easier for me to understand escaping rules? To be very precise, I'll accept an answer which tells me which characters I should escape on the bash command line? Including how to correctly output newline and exclamation mark in my example.

• Invoke ngen from NSIS installer

  - by BlackStar

  I am using NSIS to deploy a .Net application. The installation/uninstallation process works fine, but I would like to add a final ngen step to improve startup performance. Unfortunately, Google didn't reveal any relevant material. It's unlikely that noone has ever done this before - maybe someone here has some idea? In the unlikely case that this is impossible to support without ugly hacks, I would be willing to use a different installer technology provided it can run on my Linux build server. (This rules out WiX, for example.) Any ideas?

• z-index has no effect in IE7 with Google Map and Navigation Sub-Menus

  - by bhamrick

  I feel like the problem is extremely apparent. I'm working on an issue with a client's site, which actually happens on several of my clients' sites but this one is the most apparent. IE7 Is refusing to obey z-index rules. I've played around with differing values, particularly on the divs #mapWrapper and #map. Take a look here: http://thepaysongroup.com/wp-content/plugins/hq_idx/searchlistings.php I've done dozens of web searches and I can't find anything that resolves this issue. I also ready through Aleksandar Vacic's article on IE6/7 z-index discrepancies, but still nothing. Any assistance would be much appreciated, I'm tearing my hair out on this one.

• Debugging nth-child selector

  - by Ross

  I have the following selectors: .progress:nth-child(3n+1) { background: teal; } .progress:nth-child(3n+2) { background: red; } .progress:nth-child(3n+3) { background: blue; } However all of the items end up with a teal background. Are these selectors correct? I'm thinking I should get: Teal (every 3, starting with 1) Red (every 3, starting with 2) Blue (every 3, starting with 3) etc. I've tested on Firefox 3.5.8 and Opera 10.10 on Ubuntu. Also tested with nothing but these rules in the CSS. I'm using the YUI Reset stylesheet but excluding it does nothing.

• Exclude a URL from rewrite in .htaccess with "last" flag

  - by songdogtech

  WordPress has been installed as a blog into osCommerce. I'm trying to get the WordPress RSS feed to work. All WP core files exist, but I get all kinds of errors accessing the feed at mydomain.com/wordpress/feed/, like 404s, "the feed can't be updated because the source file is no longer available," or even raw php code in the browser from the osCommerce feed file. I think the problem is the rewrite rules for osCommerce, and I'm thinking if I can exclude the WP feed URL from rewrite, it will fix the feed or help find the real issue. Looking around SO, I found a solution to use the "last" flag on a URL to prevent it from being rewritten. Problem is, the existing .htaccess already has a rule with a "last" flag on it: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)/$ http://www.mydomain.com/index.php?cPath=$1 [L] Is there a way to not rewrite the WP feed URL? Can another "last" rule be added? I'd like to have some definite things to try before messing with .htaccess to avoid disrupting the site.

• Code golf: the Mandelbrot set

  Usual rules for the code golf. Here is an implementation in python as an example from PIL import Image im = Image.new("RGB", (300,300)) for i in xrange(300): print "i = ",i for j in xrange(300): x0 = float( 4.0*float(i-150)/300.0 -1.0) y0 = float( 4.0*float(j-150)/300.0 +0.0) x=0.0 y=0.0 iteration = 0 max_iteration = 1000 while (x*x + y*y <= 4.0 and iteration < max_iteration): xtemp = x*x - y*y + x0 y = 2.0*x*y+y0 x = xtemp iteration += 1 if iteration == max_iteration: value = 255 else: value = iteration*10 % 255 print value im.putpixel( (i,j), (value, value, value)) im.save("image.png", "PNG") The result should look like this Use of an image library is allowed.

• Is this a good way to manage initializations of COM?

  - by BillyONeal

  Hello everyone :) I'm very new to anything involving Component Object Model, and I'm wondering if this method of managing calls to CoInitalize/CoUninitalize makes sense: COM.hpp: #pragma once namespace WindowsAPI { namespace ComponentObjectModel { class COM { COM(); ~COM(); public: static void Setup(); }; }} COM.cpp: #include <Windows.h> #include "COM.hpp" namespace WindowsAPI { namespace ComponentObjectModel { COM::COM() { if (CoInitializeEx(NULL, COINIT_APARTMENTTHREADED) != S_OK) throw std::runtime_error("Couldn't start COM!"); } COM::~COM() { CoUninitialize(); } void COM::Setup() { static COM instance; } }} Then any component that needs COM just calls COM::Setup() and forgets about it. Does this make sense or am I breaking any "rules" of COM?

• How do I get developers to treat test code as "real" code?

  - by womp

  In the last two companies I've been at, there is an overriding mentality among developers that it's okay to write unit tests in a throw-away style. Code that they would never write in the actual product suddenly becomes OK in the unit tests. I'm talking Rampant copying and pasting between tests Code styling rules not followed Hard-coded magic strings across tests No object-oriented thought or design for integration tests, mocks or helper objects (250 line single-function tests!) .. and so on. I'm highly dissatisfied with the quality of the test code. Generally we do not do code reviews on our test assemblies, and we also do not enforce style or code analysis of them on our build server. Is that the only way to overcome this inertia about test quality? I'm looking for ideas to take to our developers, without having to go to higher management saying that we need to use resources for enforcement of test quality (although I will if I have to). Any thoughts or similar experiences?

• In Clojure - How do I access keys in a vector of structs

  - by Nick

  I have the following vector of structs: (defstruct #^{:doc "Basic structure for book information."} book :title :authors :price) (def #^{:doc "The top ten Amazon best sellers on 16 Mar 2010."} best-sellers [(struct book "The Big Short" ["Michael Lewis"] 15.09) (struct book "The Help" ["Kathryn Stockett"] 9.50) (struct book "Change Your Prain, Change Your Body" ["Daniel G. Amen M.D."] 14.29) (struct book "Food Rules" ["Michael Pollan"] 5.00) (struct book "Courage and Consequence" ["Karl Rove"] 16.50) (struct book "A Patriot's History of the United States" ["Larry Schweikart","Michael Allen"] 12.00) (struct book "The 48 Laws of Power" ["Robert Greene"] 11.00) (struct book "The Five Thousand Year Leap" ["W. Cleon Skousen","James Michael Pratt","Carlos L Packard","Evan Frederickson"] 10.97) (struct book "Chelsea Chelsea Bang Bang" ["Chelsea Handler"] 14.03) (struct book "The Kind Diet" ["Alicia Silverstone","Neal D. Barnard M.D."] 16.00)]) I would like to sum the prices of all the books in the vector. What I have is the following: (defn get-price "Same as print-book but handling multiple authors on a single book" [ {:keys [title authors price]} ] price) Then I: (reduce + (map get-price best-sellers)) Is there a way of doing this without mapping the "get-price" function over the vector? Or is there an idiomatic way of approaching this problem?

• Python: Decent config file format

  - by miracle2k

  I'd like to use a configuration file format which supports key value pairs and nestable, repeatable structures, and which is as light on syntax as possible. I'm imagining something along the lines of: cachedir = /var/cache mail_to = [email protected] job { name = my-media frequency = 1 day source { from = /home/michael/Images source { } source { } } job { } I'd be happy with something using significant-whitespace as well. JSON requires too many explicit syntax rules (quoting, commas, etc.). YAML is actually pretty good, but would require the jobs to be defined as a YAML list, which I find slightly awkward to use.

• Cython Speed Boost vs. Usability

  - by zubin71

  I just came across Cython, while I was looking out for ways to optimize Python code. I read various posts on stackoverflow, the python wiki and read the article "General Rules for Optimization". Cython is something which grasps my interest the most; instead of writing C-code for yourself, you can choose to have other datatypes in your python code itself. Here is a silly test i tried, #!/usr/bin/python # test.pyx def test(value): for i in xrange(value): i**2 if(i==1000000): print i test(10000001) $ time python test.pyx real 0m16.774s user 0m16.745s sys 0m0.024s $ time cython test.pyx real 0m0.513s user 0m0.196s sys 0m0.052s Now, honestly, i`m dumbfounded. The code which I have used here is pure python code, and all I have changed is the interpreter. In this case, if cython is this good, then why do people still use the traditional Python interpretor? Are there any reliability issues for Cython?
