• Is there any project estimation tool to give estimate for web design/ development work?

  - by jitendra

  Is there any project estimation tool which gives estimates for web design/ development work? I don't have to calculate Price just want to calculate estimated time. Just for example, for things like: Page creation (layout in XHTML) CSS creation Content creation (Word to HTML, including images in some pages) Bulk PDF upload PHP Script for Form Testing all pages I need like Items Quantity Time for each task(min) Estimated total (in hour) PDF upload x 30 = 2 min = 60 Min pages with images x 30 = 15 min for each = 60 Min Is there any simple JQuery calculator power with JQuery? Where we can add add/remove custom thing to calculate time? Or any other free online/offline tool ?

• Infix to Postfix and unary/binary operators

  - by Jaapjan

  I have a piece of code that converts an infix expression to an expression tree in memory. This works just fine. There's just one small trouble. I just connect work out how to involve the unary operators correctly (the right associative ones). With the following infix expression : +1 + +2 - -3 - -4 I would expect an RPN of: 1+2++3-4-- Yet, none of the online infix-post converters I can find handle this example in the way I would expect. Does anyone have a clear explanation of handling right associative operators, specifically the binary ones that can be mistaken for the unary ones?

• C++ Ambiguous call to Overloaded Function (const variety)

  - by Joe

  After researching this online, I've only found solutions that don't apply to my problem, so please bear with me. Code snippet: typedef my_map_t<int const *, float> _test; my_map_t::const_iterator not_found = my_map_t::end(); if (_test.find(&iKeyValue) == not_found) { _test[iKeyValue] = 4 + 5; // not the actual code, but here for simplicity } The compiler complains that there's an ambiguous call to my_map_t::end(). This makes sense, because the only difference is the return type. Output: error C2668: 'std::_Tree<_Traits>::end' : ambiguous call to overloaded function Normally you can disambiguate the call by casting the parameters, but end() has no parameters. Any ideas?

• How to prepare for a Java test?

  - by Zenzen

  Ok so in two days I have a test for my dream job (well it's an internship, but still!) and for quite some time now I've been reading the SCJP Guide book in order to prepare myself. BUT seeing how slow my reading speed is I guess finding a website with some "java essentials" or "standard java test questions" and going through it in those 2 days would be a better idea. Don't misunderstand me, I do have java experience and it's "only" an internship, but we all know how programming tests look like and how tricky they can be. So are there any online resources you could recommend me? I know 2 days is not much, but well I was informed bout the test 1-2days ago.

• Parsing JPEG file format: Format of entropy-coded segment (ECS) segments?

  - by me2

  I'm having difficulty understanding the ITU-T T.81 spec for the JPEG file format. Hopefully someone else here has tried to parse JPEG files and/or knows about the details of this file format. The spec indiates that the ECS0 segment starts after the SOS segment but I can't find where in the spec it actually talks about the format of the ECS0 segment or how do detect its start. Simple JPEG implementations online are of limited help because they assume many things about the JPEGs they parse. Can anyone point me in the right direction?

• How can I skip the current item and the next in a Python loop?

  - by uberjumper

  This might be a really dumb question, however I've looked around online, etc. And have not seen a solid answer. Is there a simple way to do something like this? lines = open('something.txt', 'r').readlines() for line in lines: if line == '!': # force iteration forward twice line.next().next() <etc> It's easy to do in C++; just increment the iterator an extra time. Is there an easy way to do that in Python? I would just like to point, out the main purpose of this question is not about "reading files and such" and skipping things. I was more looking for C++ iterator style iteration. Also the new title is kinda dumb, and i dont really think it reflects the nature of my question.

• How do you implement file drag-and-drop upload in Google Chrome?

  - by Chris R

  I've found several tutorials online about implementing file drag/drop with Firefox 3.6 (they involve using a FileReader object to get the file binary data). However, I cannot create a FileReader object in Chrome on Windows or Mac. Does anyone know what the API is to read and manipulate data from a drag-and-dropped file in Chrome? If I can get the binary data of the file, I already have the rest of the code to perform the upload. Note: I've also tried using the getAsBinary() function call on the file object of the drag event (event.dataTransfer.file) but I believe that is a Mozilla-specific function and not implemented in Chrome. Also, I'm not interested in a solution using google gears or one that requires a user to select files from a dialog. I'm specifically trying to implement a drag-and-drop file upload.

• Is wordpress a good platform for webapp development?

  - by darlinton

  I am planning a webapp to control bank paying orders. In a quick review, the user goes online and creates a payment order. This order goes to other people that pays it and register the payment on the system. The system keeps track of all the payments, keeping the account balance up-to-date. The system needs a login system, bank integration, and to support at some point thousands of clients. We can find articles on the web about the benefits of using wordpress platform to build webapps. However, I could not find discussion with counterarguments to user wordpress. As the platform the most important choice in webapp project, I would to know more about the pitfalls and harms for choosing wordpress. The question is: What are the benefits and harms for choosing wordpress as a development platform for a webapp that need to be integrated with other system (backend systems) and to handle thousands of users (does it scale up?)?

• gdata youtube api 302 'The document has moved'

  - by zalew

  I'm trying to get YouTube feeds with the python gdata library. Authentication features work ok, yt_service.ProgrammaticLogin() works, generating subauth token works, etc., but when I try to get some feeds (GetMostRecentVideoFeed, GetYouTubeVideoEntry, even GetFeed, and any other) I get: RequestError: {'status': 302, 'body': '<HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">\n<TITLE>302 Moved</TITLE></HEAD><BODY>\n<H1>302 Moved</H1>\nThe document has moved\n<A HREF="http://www.google.com">here</A>.\r\n</BODY></HTML>\r\n', 'reason': 'Redirect received, but redirects_remaining <= 0'} 302 to 'google.com'???

• Deploying web service

  - by baron

  I am trying to build a webservice that manipulates http requests POST and GET. Here is a sample: public class CodebookHttpHandler: IHttpHandler { public void ProcessRequest(HttpContext context) { if (context.Request.HttpMethod == "POST") { //DoHttpPostLogic(); } else if (context.Request.HttpMethod == "GET") { //DoHttpGetLogic(); } } ... public void DoHttpPostLogic() { ... } public void DoHttpGetLogic() { ... } I need to deploy this but I am struggling how to start. Most online references show making a website, but really, all I want to do is respond when an HttpPost is sent. I don't know what to put in the website, just want that code to run. Some links i've tried so far: http://my.execpc.com/~gopalan/dotnet/webservices/webservice_server.html http://www.beansoftware.com/asp.net-tutorials/deploy-asp.net.aspx http://msdn.microsoft.com/en-us/library/6x71sze4%28VS.80%29.aspx http://www.c-sharpcorner.com/UploadFile/rajaduraip/SimplestwaytoCreateNDeployWebServices12232005054219AM/SimplestwaytoCreateNDeployWebServices.aspx

• Creating a directory in linux assembly language

  - by Jayson Kane

  I am trying to create a small assembly program to create a folder. I looked up the system call for creating a directory on this page: http://www.ctyme.com/intr/rb-8144.htm It says that it is identified by 27h. How would I go about implementing the "mkdir somename" in assembly? I am aware that the program should move 27 into eax but I am unsure where to go next. I have googled quite a bit and no one seems to have posted anthing about this online. This is my current code (I don't know in which register to put filename and so on) section .data section .text global _start mov eax, 27 mov ???????? .... int 80h Thanks

• multiple login pages in ASP.NET forms authentication

  - by Brad

  My bank's website has 2 login pages for online banking. On the first page, I enter my username. If I don't enter a valid username, I get an error message, and do not get to the 2nd page. The 2nd page displays a picture based on my user name, and has me enter my password. If I manually type a URL to a page inside the site after entering my username but before entering my password, I am redirected back to the first login page. Is there a good way to implement this in ASP.NET with Forms Authentication? I only get 1 loginUrl in my web.config. I am fairly certain my bank uses Java.

• Multiple merchant accounts with Activemerchant gem.

  - by sosborn

  I am developing a rails site that will allow a group of merchants (5 - 10) to accept credit card orders online. I plan on using the Activemerchant gem to handle the processing. In this case, each merchant will have their own merchant accounts to handle the payments. Storing banking information like that is not something I am a fan of. This could be solved by queing orders and allowing the merchant to log in to the site, input their credentials and process the order. However, if I go that route then it seems to me that I would have to store the customers' credit card information temporarily until the merchant has the opportunity to log in and process the order, which to me is the greater evil. Has anyone dealt with this situation? If so, what are the options available and what pitfalls should I look out for? In my mind, security customer credit card information is priority number one with the merchant account information a close second.

• How to give you website customers a secure feeling

  - by Saif Bechan

  I was wondering how you can give your website customers the confidence that you are not tinkering with the database values. I am planning on running a website which falls in the realm of an online game. There is some kind of credit system involved that people have to pay for. Now I was wondering how sites like this ensure there customers that there is no foul play in the database itself. As I am the database admin i can pretty much change all the values from within without anyone knowing i did. Hence letting someone win that does not rightfully is the winner. Is it maybe an option to decrypt en encrypt the credits people have so i can't change them. Or is there maybe a company i can hire that checks my company for foul play.

• Alternative to google map api, so that I can use it on a HTTPS/SSL encrypted website.

  - by Zeeshan Rang

  I have a question regarding map api. I was using the the google map api in my website before. But since I have encryption the site using HTTPS/SSL support, the google map api stopped working. I checked online, and realised that google has a Premier account only that would allow me to use HTTPS supported maps api and it cost $10,000 per year. I do not this kind of money with me. So, can you give any other alternative to have a map api on my website. Anything that could give me driving directions would be fine. Regards Zeeshan

• How to set up 3rd party developer portal

  - by Michael

  I am developing a web service and depend on 3rd party developers to write client applications for it. I need to set a developer portal, a web site where existing and potential developers would find documentation html pages doc files for download libraries downloads wiki forums support ticketing system. There should be a public part and a part protected by login. I want only logged in users to submit tickets, for example. I don't want to host it. I would prefer a generic design based on a sensible template, where I can add minimal customization, such as logo. I don't want to add code to get any of the above functionality. I will do all that if necessary, but I'd hope there would be an online service to do thing like that. What services would you guys recommend?

• Drag and drop: jQuery UI or Scriptaculous?

  - by jpartogi

  Dear all, I am in the middle of the road whether to use jQuery UI or Scriptaculous for drag and drop. I am using Ruby on Rails, and Scriptaculous support in Ruby on Rails is superb with the existence of scriptaculous_helper.rb. But I have already use jQuery for the ajax and DOM manipulation. I do not mind to use scriptaculous since we can use jQuery.noConflict() in the code. I also kind of get the impression that scriptaculous drag and drop is better than jQuery UI drag and drop based on the online demos. So back to the original question, which one would you recommend as a drag and drop library and which one do you think is better than the other? Scriptaculous or jQuery UI?

• How to use Netbeans platform syntax highlight with JEditorPane?

  - by Volta

  There are many tutorials online giving very complex or non-working examples on this. It seems that people recommend others to use the syntax highlighters offered by netbeans but I am totally puzzled on how to do so! I have checked many many sites on this and the best I can find is : http://www.antonioshome.net/kitchen/netbeans/nbms-standalone.php However I am still not able to use this example (as it is aimed to people who don't want to use the Netbeans platform but just a portion of it) and I am still not sure if I can just use syntax highlighting in a simple plug 'n play way. For example netbeans supports several language highlights by default, can I just use the highlighters in a JEditorPane to parse Ruby/Python/Java for example ? or do I need to write my own parser :-| ? I will really appreciate a small simple example on how to plug syntax highlight in a standalone application using the netbeans platform.

• referencing a WCF web service

  - by ErnieStings

  Our current project uses an asmx service. We want to keep this service for now, but would like to add an additional wcf service for ajax calls. I followed a procedure i found online to set up the service and it works fine with javascript in aspx files within that particular project but i'm unsure how to reference it in javascript files in a different project (in the same solution). If someone could point me in the right direction it would be much appreciated. Thanks, Shawn EDIT: i wish to make calls in javascript similar to the following: function Button1_onclick() { var service = new AjaxServices.TestService(); service.wcfTest(4, onSuccess, null, null); } function onSuccess(result){ document.getElementById("ajaxPlaceHolder").innerHTML = "<p>" + result + "</p>"; } // ]]> but i'm willing to explore the jQuery option as well.

• sending instant messages through python (msn)

  - by code_by_night

  ok I am well aware there are many other questions about this, but I have been searching and have yet to find a solid proper answer that doesnt revolve around jabber or something worse. (no offense to jabber users, just I don't want all the extras that come with it) I currently have msnp and twisted.words, I simply want to send and receive messages, have read many examples that have failed to work, and msnp is poorly documented. My preference is msnp as it requires much less code, I'm not looking for something complicated. Using this code I can login, and view my friends that are online (can't send them messages though.): import msnp import time, threading msn = msnp.Session() msn.login('[email protected]', 'XXXXXX') msn.sync_friend_list() class MSN_Thread(threading.Thread): def run(self): msn.start_chat("[email protected]") #this does not work while True: msn.process() time.sleep(1) start_msn = MSN_Thread() start_msn.start() I hope I have been clear enough, its pretty late and my head is not in a clear state after all this msn frustration. edit: since it seems msnp is extremely outdated could anyone recommend with simple examples on how I could achieve this? Don't need anything fancy that requires other accounts.

• How to properly use Gearman with my PHP application?

  - by luckytaxi

  For now I just want to use Gearman for background processing. For example, I need to email a recipient that they have a private message waiting for them once the sender submits their message into the DB. I assume I can run the worker/client and server on my primary server but I have no problems offloading some of the tasks to a different web server. Anyways, my question is how do I handle multiple "functions?" Let's say I need a job that handles the email portion and a job to handle image manipulation. Can I have multiple functions in the worker? I've followed a couple of examples I found online but each example only shows one function being initialized. Do I have to start up multiple "workers" to handle multiple functions?

• possible to create sql query with table wildcards?

  - by Rees

  this is probably a simple question, but i have been unable to find a solution online, any help would be much appreciated. I'm trying to create an SQL query in PHP and would like to somehow apply a wild card to the TABLE filter... something perhaps like.... select * from %table%. However, I have only so far been able to see filters for column values not table names. as an example i would have tables such as: jan_table_1 feb_table_1 jan_table_2 feb_table_2 and would want to say, select only tables with a "jan" prefix... or "1" suffix. Is there a quick and easy solution to this that I have not seen? Thanks in advance!

• Default Database Collations PenTesting Env

  - by dominicdinada

  I am using Ubuntu 9.10 with XAMPP ( Lampp "MYSQL 5.1.45 PHPMYADMIN 3.3.1 PHP 5.3.2 ) What my problem is, is that I set up my testing env to debug my scripts locally and when I did so there arose a problem. This problem is that I used firefox's addon SQLinject ME to test for weakness' and upon doing so it caused mysql to change the default local collations; character sets dir /opt/lampp/share/mysql/charsets/ collation connection latin1_general_ci (Global value) latin1_swedish_ci collation database latin1_swedish_ci collation server latin1_swedish_ci I have searched for quite sometime in regards to a solution to this problem and have come up with searching for the db.opt file which stores this information without success. Upon not finding a solution I removed lampp with the "sudo rm -fR /opt" command and reinstall and the problem still persists. I have tried to change the collations manually and still come up with the database displaying latin1_swedish_ci as the default language. Why is this a problem?? Why is it a problem with mysql? Because the application I am testing and debugging locally is built on the CodeIgnitor with Smarty framework and since this combination of framework is built to detect the LOCALES, Rather what the database defaults are I keep getting errors saying no language file for swedish...... Of course I could get the swedish language file to work around this problem but I do not feel the need to make this work around a perminant solution as with time when I move on to projects I will run into simular problems every time that A; When importing database files, backups etc it will default to import such databases as the locale swedish. B; As time passes on I might completly forget of this error and will be back to square one. I have found this code in searches for a fix,which seems to alter the tables to a desired Collaion; $value) { mysql_query("ALTER TABLE $value COLLATE latin1_general_ci"); }} echo "The collation of your database has been successfully changed!"; ? Which is handy to switch collations in One Schema at a time however this is not a fix when a framework doesnt care that the said database is in one langugae. It tests for the Default of the entire server. Someone with any knowledge of a purge or fix to this I would greatly appricate the help. One more final note is that when I was testing I only figured to back up the applications DataBase and not the entire Schema of the install. No matter if I uninstall or reinstall the database still seems to carry these problems.

• Making GWT application crawlable by a search engine.

  - by Philippe Beaudoin

  I want to use the #! token to make my GWT application crawlable, as described here: http://code.google.com/web/ajaxcrawling/ There is a GWT sample app available online that uses this, for example: http://gwt.google.com/samples/Showcase/Showcase.html#!CwRadioButton Will serve the following static webpage to the googlebot: http://gwt.google.com/samples/Showcase/Showcase.html?_escaped_fragment_=CwRadioButton I want my GWT app to do something similar. In short, I'd like to serve a different flavor of the page whenever the _escaped_fragment_ parameter is found in the URL. What should I modify in order for the server to serve something else (a static page, or a page dynamically generated through a headless browser like HTML Unit)? I'm guessing it could be the web.xml file, but I'm not sure. (Note: I thought of checking the Showcase app provided with the GWT SDK, but unfortunately it doesn't seem to support serving static files on _escaped_fragment_ and it doesn't use the #! token..)
