• What is the best regular expression for validating email addresses?

  - by acrosman

  Over the years I have slowly developed a regular expression that validates MOST email addresses correctly, assuming they don't use an IP address as the server part. Currently the expression is: ^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$ I use this in several PHP programs, and it works most of the time. However, from time to time I get contacted by someone that is having trouble with a site that uses it, and I end up having to make some adjustment (most recently I realized that I wasn't allowing 4-character TLDs). What's the best regular expression you have or have seen for validating emails? I've seen several solutions that use functions that use several shorter expressions, but I'd rather have one long complex expression in a simple function instead of several short expression in a more complex function.

• Javascript object encapsulation that tracks changes

  - by Raynos

  Is it possible to create an object container where changes can be tracked Said object is a complex nested object of data. (compliant with JSON). The wrapper allows you to get the object, and save changes, without specifically stating what the changes are Does there exist a design pattern for this kind of encapsulation Deep cloning is not an option since I'm trying to write a wrapper like this to avoid doing just that. The solution of serialization should only be considered if there are no other solutions. An example of use would be var foo = state.get(); // change state state.update(); // or state.save(); client.tell(state.recentChange()); A jsfiddle snippet might help : http://jsfiddle.net/Raynos/kzKEp/ It seems like implementing an internal hash to keep track of changes is the best option. [Edit] To clarify this is actaully done on node.js on the server. The only thing that changes is that the solution can be specific to the V8 implementation.

• How do I clear the text contents of a div in javascript?

  - by Ben

  I'm temporarily adding contents to a div,tempDiv, and adding that to a link which is appended to a div, #contentHere, that's displayed. I need to clear the contents of tempDiv so that the links aren't appended to each other, creating a string of urls that don't link to anywhere. $(document).ready(function(){ $.getJSON("data.php", function(data){ for(i = 0; i < 5; i++){ $("#tempDiv").append(data.justIn[i].dataLink+ ' '); $("#contentHere").append("<a href=\"#tempDiv\">Click to go to the div link</a>"); //I need to clear the contents of tempDiv here } }); }); Solutions to clearing the temporary contents of the div as I go?

• input URL, output contents of "view page source", i.e. after javascript / etc, library or command-li

  - by Ryan Berckmans

  I need a scalable, automated, method of dumping the contents of "view page source" (DOM) to a file. Programs such as wget or curl will non-interactively retrieve a set of URLs, but do not execute javascript or any of that 'fancy stuff'. My ideal solution looks like any of the following (fantasy solutions): cat urls.txt | google-chrome --quiet --no-gui \ --output-sources-directory=~/urls-source (fantasy command line, no idea if flags like these exist) or cat urls.txt | python -c "import some-library; \ ... use some-library to process urls.txt ; output sources to ~/urls-source" As a secondary concern, I also need: dump all included javascript source to file (a la firebug) dump pdf/image of page to file (print to file)

• Is it possible to run php exec through cygwin?

  - by Scarface

  Hey guys I have one command that works on my remote linux server but not my windows (WAMP package) local server. I really want to create an identical workstation so I can test locally and then update my remote server. If anyone has any suggestions or solutions other than converting to linux, I would really appreciate it. <?php $safe_path = escapeshellarg('fake-virus.txt'); $command = '/usr/bin/clamscan --stdout ' . $safe_path; $out = ''; $int = -1; exec($command, $out, $int); echo $int; if ($int == 0) { // all good; } else { echo 'o no';// VIRUS!; } ?>

• Making dynamic images have static filenames

  - by michaeltk

  My website currently has various links to a php script that generates the images dynamically. For example, the link may say "img source="/dynamic_images.php?type=pie-chart&color=red" Obviously, this is not great for SEO. I'd like to somehow make the filenames of these links appear to be static, and use a solution (like Mod-Rewrite) to ensure that the images can still be dynamically created. I suppose I could have something like "img src="average-profits-in-scuba-diving-industry.png?type=pie-chart&color=red" (and use Mod-Rewrite to take care of changing the filename prefix to dynamic_images.php), but I'm afraid that the search engines would shy away from the querystring on the end of the image filename. Any solutions? Thanks in advance.

• Firefox: how to apply XSLT from plugin to opened XML document? (how to replace document with another

  - by aloispaulin

  Hi! I've developed a plug-in for Firefox, that can read and manipulate the content of the currently opened document. I would like to apply a XLST to the document in case it is XML. I have no problem to read the XML document and apply a XSLT to it in memory, however, I have no idea of how to replace the existing document with the newly created one. Thus, I see two possible scenarios: a) I replace the document with the result of the transformation b) I apply the XSLT directly to the XML All my attempts to realize one of both possible solutions have failed... Hoping the community can provide help! Many tnx in advance! Alois

• User-customizable rails authorization

  - by neutrino

  Hello everyone, Seems there is an abundance of popular declarative-style authorization plugins, which allow you to somehow state in the code that, e.g., this controller action can be accessed by users with such-and-such roles. But what if I need a more dynamic scheme. I want to have an admin area, with a list of all authorizable actions and an ability to assign permissions on actions from the UI. I have ideas how to implement it from scratch, like to define a model corresponding to a controller and/or action and store the permissions via normal associations. Just wonder if there are any ready solutions to this. Thanks a lot

• How to detect first or last element iterating over a container?

  - by Basilevs

  How to do the following in more stylish/short way? for(i=container.begin(); i!=container.end(); ++i) { if (i!=container.begin()) { cout << ", "; } cout << *i; if (i==container.end()) { cout << "!" << endl; } } Solutions like foreach are acceptable (actions on first and last elements need to be configurable, though).

• Rails Rspec testing not saving a transactional model

  - by NolanDC

  I'm currently testing my Rails controllers using RSpec. In one controller, I have a model that uses transactions, so that it will not be saved unless another nested model (whose data is filled in using fields_for) is also saved correctly. The tests hit a snag when they reach the transaction. Some debugging output proves that the model is valid and ready to save. However, upon entering the transaction block, the model does not save. Even stranger, the code never reaches the else clause of "if model.save" (It does, however, enter the transaction block). I can only assume this is a problem with my testing a transactional model. Any ideas/hints/solutions?

• Graphical Submit button doesn't 'post' in Firefox or IE

  - by Ken

  I've looked all over the net to try and solve this problem, but I can't find any solutions. So far, I've checked 3 different browsers. It does not work on IE or FireFox, but it works just fine in Safari. Here's the problem. When I click the button to submit my form, it forwards me to the 'post' URL page - INSTEAD of posting the data, and going to the thank you page like the script commands. Here's the code I'm working with: <form name="loginfrm" method="post" action="http://www.myaffiliatepowersite.com/members/quick_signup.php" style="margin:0; padding:0;"> " /

• Mysql search design

  - by neil

  I'm designing a mysql database, and i'd like some input on an efficient way to store blog/article data for searching. Right now, I've made a separate column that stores the content to be searched - no duplicate words, no words shorter than four letters, and no words that are too common. So, essentially, it's a list of keywords from the original article. Also searched would be a list of tags, and the title field. I'm not quite sure how mysql indexes fulltext columns, so would storing the data like that be ineffective, or redundant somehow? A lot of the articles are on the same topic, so would the score be hurt by so many of the rows having similar keywords? Also, for this project, solutions like sphinx, lucene or google custom seach can't be used -- only php & mysql. Thanks!

• Calculate a div's height with jQuery - minus header and footer

  - by Dirty Bird Design

  I'm using a sticky footer (negative margin solution) and it works fine. What I need to do is calculate the window's height, subtract the known height of the header and footer then apply that number and use it for the height of the main wrapper div. CSS solutions cause other issues, is there a good way to do this? var h = window.height(); var k = 300; //header is 100px footer is 200px $('#wrap').height(h-k); rough idea, pls help.

• dropdown list event is not firing when javascript is used

  - by user1511953

  i have a problem in firing dropdownlist event i have following dropdown asp:dropdownlist id="ddlhello" Runat="server" AutoPostBack="True" onchange="javascript:return ChangeHeader();" i have also added event in code behind i.e. selectedindex change event. Now problem occurs when i execute the page, it executes javascript but server side code doesnot fire, but if i remove this line onchange="javascript:return ChangeHeader();" then server side code fires. when i checked source page it shows me two onchange events associated one for javascript and other for server side. i think that it is picking client side code and neglects server side. I am not pretty sure, so i want to know the behavior reason. And what is the way out for this. i want server and client side code to be executed. i have searched for solutions but i have not found any correct reason. please reply for the same. Thanks in advance

• How to host a naked domain on a CDN?

  - by rjw79

  If I have a domain that I wish to serve "naked" eg http://examp.le/, and efficiently with a CDN, what are my options? The issue is that the CDNs I looked at all want you to use a CNAME so that they can do geo ip lookup. CNAMES are not meant to be served at the same level as other records, and this apparently breaks some dns resolvers. You at least need SOA and MX records at the same level for a naked domain. The only solutions are: having A records in your own dns, thus skipping the geo ip, or finding a cdn who will allow delegation of the whole domain so they can do geo ip things for the A record directly. I've tried googling and can't find any Cdn who offers this. Any ideas? I looked closely at Amazon cloudfront and rackspace cloudfiles. I couldn't work it out for those.

• Is catching NumberFormatException a bad practice?

  - by integeruser

  I have to parse a String that can assume hex values or other non-hex values 0xff, 0x31 or A, PC, label, and so on. I use this code to divide the two cases: String input = readInput(); try { int hex = Integer.decode(input); // use hex ... } catch (NumberFormatException e) { // input is not a hex, continue parsing } Can this code be considered "ugly" or difficult to read? Are there other (maybe more elegant) solutions? EDIT : I want to clarify that (in my case) a wrong input doesn't exist: i just need to distinguish if it is a hex number, or not. And just for completeness, i'm making a simple assebler for DCPU-16.

• Regular Expression to Match All Characters after another Regex Match

  - by Anthony Wood

  I know this may sound a little confusing, so I am open to suggestions on renaming the title. Basically I have string such as C:...\Downloads\Folder\SubFolder\SubSubFolder. and I want to return the SubFolder and SubSubFolder only. So far, my Regex looks like (?=\\Downloads\\.*?\\).* which matches Downloads\Folder\SubFolder\SubSubFolder. Does anybody have any Ideas what I am missing???? All the solutions below seem to work (except if you didn't know "Folder"). Potentially a bug with the tool I was using to test the regular expressions.

• Detecting coincident subset of two coincident line segments

  - by Jared Updike

  This question is related to: How do I determine the intersection point of two lines in GDI+? (great explanation of algebra but no code) How do you detect where two line segments intersect? (accepted answer doesn't actually work) But note that an interesting sub-problem is completely glossed over in most solutions which just return null for the coincident case even though there are three sub-cases: coincident but do not overlap touching just points and coincident overlap/coincident line sub-segment For example we could design a C# function like this: public static PointF[] Intersection(PointF a1, PointF a2, PointF b1, PointF b2) where (a1,a2) is one line segment and (b1,b2) is another. This function would need to cover all the weird cases that most implementations or explanations gloss over. In order to account for the weirdness of coincident lines, the function could return an array of PointF's: zero result points (or null) if the lines are parallel or do not intersect (infinite lines intersect but line segments are disjoint, or lines are parallel) one result point (containing the intersection location) if they do intersect or if they are coincident at one point two result points (for the overlapping part of the line segments) if the two lines are coincident

• What frameworks should we consider for a custom web application?

  - by justkevin

  A client is looking for a custom web application, which will eventually include lots of interconnected components, but the main features are: Subscription based membership as well as virtual/digital product sales Members have their own public web cookie-cutter directories (e.g., storefronts, pages, etc.) and personal member admin area. Site administrators will need both common tools (member admin, password changes, etc.) and custom tools that can be readily developed or integrated with 3rd party solutions. What frameworks should we be looking at? PHP/MySQL is preferable unless something really outstanding is available in another stack.

• Is it possible to run the Android emulator as root from NetBeans on the Mac

  - by catwallader

  I have installed NetBeans 6.8 on my MacOS (Leopard) system and use the Kenai plugin for this platform to create an Android application. The trouble is that I cannot run the Android emulator from NetBeans logged in to the Mac as a normal user. I can run the emulator from the command line and the Eclipse environment when logged in as root. When I try to run NetBeans as root, it displays a message indicating many of components of the Android plugin cannot be loaded because the root user somehow links to Java 1.5 and the plugin needs Java 1.6. There are 3 solutions to this problem as far as I can see: Make the root user environment link to Java 1.6 and use NetBeans as root. Coerce NetBeans to su to root before running the Emulator. Stick to using Eclipse for Android development. If anyone knows how how to do 1 or 2 I would appreciate getting advice from you. Thanks in advance.

• Makefile: expand dependencies

  - by Danyel

  First off, the title is very generic because there are just tons of ways of how to possibly solve this. However, I'm looking for a clean and neat way. Situation: I have two equal object files foo.o and foo-pi.o, the latter of which is position-independent (compiled with -fPIC). Both depend on foo.h and bar.h. Problem: How do I, without code duplication, declare dependency of all foo*.o to bar.h? Solutions so far: $(shell bash -c 'echo -ne foo{-pi,}.o'}: bar.h $(addsuffix .o, $(addprefix fo, o-pi o)): bar.h The first solution is not portable on systems that don't support bash, the second is a dirty solution since I could not figure out how to use empty strings in addprefix.

• Why the valid looking statement gives error in MATLAB?

  - by user198729

  It's from this question? Why the two solutions doesn't work, though it looks very valid for me: >> t = -pi:0.1:pi; >> r = ((sin(t)*sqrt(cos(t)))*(sin(t) + (7/5))^(-1)) - 2*sin(t) + 2 ; ??? Error using ==> mtimes Inner matrix dimensions must agree. >> t = -pi:0.1:pi; >> r = ((sin(t).*sqrt(cos(t))).*(sin(t) + (7/5)).^(-1)) - 2*sin(t) + 2 ; >> plot(r,t) ??? Error using ==> plot Vectors must be the same lengths. What's wrong with the above?

  Hello, How can it be done in most simply way to write (or maybe there is something embedded in haskell) function which takse as arguments list of tuples (String, Int) and Int x and return top x tuples as list according to x value. I wonder if its possible to write a function which also takes 3 argument which is the name of (or index) of filed in tuple according to which sorting has to be done. What are best solutions to make it quite generic, Im new to haskell I would do somethink like that in imperative languages without any problems but I want to know how to write it in quite good way in haskell, thanks for help
