• I never really understood: what is CGI?

  - by claws

  CGI is a Comman Gateway Interface. As the name says, it is a "common" gateway interface for everything. It is so trivial and naive from the name. I feel that I understood this and I felt this every time I encountered this word. But frankly, I didn't. I'm still confused. I am a PHP programmer. I did lot of web development. user (client) request for page --- webserver(-embedded PHP interpreter) ---- Server side(PHP) Script --- MySQL Server. Now say my PHP Script can fetch results from MySQL Server && MATLAB Server && Some other server. So, now PHP Script is the CGI? because its interface for the between webserver & All other servers? I don't know. Sometimes they call CGI, a technology & othertimes they call CGI a program or someother server. What exactly is CGI? Whats the big deal with /cgi-bin/*.cgi? Whats up with this? I don't know what is this cgi-bin directory on the server for. I don't know why they have *.cgi extensions. Why does Perl always comes in the way. CGI & Perl (language). I also don't know whats up with these two. Almost all the time I keep hearing these two in combination "CGI & Perl". This book is another great example CGI Programming with Perl Why not "CGI Programming with PHP/JSP/ASP". I never saw such things. CGI Programming in C this confuses me a lot. in C?? Seriously?? I don't know what to say. I"m just confused. "in C"?? This changes everything. Program needs to be compiled and executed. This entirely changes my view of web programming. When do I compile? How does the program gets executed (because it will be a machine code, so it must execute as a independent process). How does it communicate with the web server? IPC? and interfacing with all the servers (in my example MATLAB & MySQL) using socket programming? I'm lost!! They say that CGI is depreciated. Its no more in use. Is it so? What is its latest update? Once, I ran into a situation where I had to give HTTP PUT request access to web server (Apache HTTPD). Its a long back. So, as far as I remember this is what I did: Edited the configuration file of Apache HTTPD to tell webserver to pass all HTTP PUT requests to some put.php ( I had to write this PHP script) Implement put.php to handle the request (save the file to the location mentioned) People said that I wrote a CGI Script. Seriously, I didn't have clue what they were talking about. Did I really write CGI Script? I hope you understood what my confusion is. (Because I myself don't know where I'm confused). I request you guys to keep your answer as simple as possible. I really can't understand any fancy technical terminology. At least not in this case. EDIT: I found this amazing tutorial "CGI Programming Is Simple!" - CGI Tutorial Which explains the concepts in simplest possible way. I've only have one complaint about this tutorial. Just to make what ever he explained complete he should have shown the C code he used for generating response for those GET / POST requests. I've also added link to this tutorial to Wikipedia's article : http://en.wikipedia.org/wiki/Common_Gateway_Interface

• Rails Action and Fragment Caching during Development?

  - by viatropos

  I'm just starting to get into Rails caching and am wondering how to test whether or not caching is working in my development environment. I have set these two config variables for both the development (temporarily) and production environments: config.action_controller.perform_caching = true config.action_controller.page_cache_directory = File.join(RAILS_ROOT, 'public', 'cache') And my controller basically looks like this (using the resource_controller gem): class EventsController < Spree::BaseController resource_controller caches_page :index index.response do |format| format.html format.xml { render :xml => @collection.to_xml } end # ... end If I do that, I get these files: public/cache/events.html public/cache/events.xml But when I change caches_page to caches_action, I don't see any generated files and am not sure how to tell if the response has been cached. What do I need to know to know that this is working? I've read the docs and related, the rails caching guides, the railscast, and a few other docs, but I'm still wondering where everything is stored. Thanks!

• Is this design possible with ExtJS?

  - by gargantaun

  I've been asked to do the front end for a web app, and to use ExtJS specifically. I've been working through a couple of tutorials, but I've not seen much variation on the default ExtJS look and feel except for some subtle changes to the colors and what not. The design I've been handed seems to be a radical departure from the standard ExtJs look and feel. So before I head down a dead end or start chasing wild geese, I wondered wether any ExtJS experts out there could point out any potential pit falls in the design, or is everything do-able? The design is here... cheers -t

• JSF Custom EL function works only on the first load of the page.

  - by jsfQ

  I created a ( JSP-based) custom EL function to use in the rendered tag. The function will return a boolean to decide if a page component needs to be rendered on a page or not. I import it onto the jsp page using <%@ taglib uri = "/WEB-INF/mine.tld" prefix = "g" %. Everything works perfect on the first load of the jsp page. Once a button is clicked, the form submits and then I am getting errors like 'No ClassLoaders found for: the class which implements my EL function' and 'Function not found'. What is going on here? What will be a fix?

• Interchanging presentModalViewController and pushViewController

  - by Neffster

  I am using a sample ViewController that is displayed in the sample program as a presentModalViewController. However, I want to use pushViewController on the UIViewController instead. The problem is that when I switch to pushViewController, the ViewController no displays properly. Functions in the ViewController are called, but I don't see anything. I change back to presentModalViewController and everything works. The question is what do I need to do to make pushViewController work? FCVC *fcVC; NSArray *array = [[NSBundle mainBundle] loadNibNamed:@"fcVC" owner:self options:nil]; fcVC = [array objectAtIndex:0]; A. [self presentModalViewController:fcVC animated:YES]; // "WORKS" or B. [self.navigationController pushViewController:fcVC animated:YES]; // "Doesn't work

• Replacing Credit Card Numbers

  - by Del

  Hi, I'm using an sql to replace credit card numbers with xxxx and finding that REGEX_REPLACE does not consistently replace everything. Below is the SET command i'm using on the SQL SET COMMENTS_LONG = REGEXP_REPLACE (COMMENTS_LONG,'\D[1-6]\d{3}.\d{4}.\d{4}.\d{3}(\d{1}.\d{3})?|\D[1-6]\d{12,15}|\D[1-6]\d{3}.\d{3}.?\d{3}.\d{5}', ' XXXXXXXXXXXXXXXX') Before Elizabeth aclled to change address.5430-6000-2111-1931 A After Elizabeth aclled to change address XXXXXXXXXXXXXXXX1 A I tried increasing the number of X but result is the same. I also find that i have to put a space in front of the first X as it appears to move 1 char to the left.

• Modifying an old Windows program not to call exit after a keypress without source access

  - by rustyn2

  I have an older C++ Windows program that I've been asked to get run in a kiosk style environment for a student project. From the main menu, hitting ESC will exit the program, which is undesirable. In ye olden days I would have trapped the keyboard interrupt or whatever and dug around to NOOP whatever JMP or CALL was getting referenced in the case statement that likely decides all that, but on Windows everything goes through various registered event handlers, and I haven't done any windows internals work in about 10 years. Is there a good tool to breakpoint a program on certain WM_EVENT (WM_KEYDOWN being a prime target) messages or similar, so that I can narrow down where in the executable the check is made? I'm currently stepping back from various potential system calls made before the various thread cleanups and final exit calls but it seems like there has to be a better way to do this that I'm forgetting.

• How to decode Google spreadsheet's Json respose as a Php Array

  - by Mohammad

  My google Docs Spreadsheet call returns this response in the json format (I only need everything after "rows") please look at the formatted response here : ) I use php's json_decode function to parse the data and use it (Yes, I am awful at php) This code returns NULL, and according to the documentation, NULL is returned "if the json cannot be decoded". $json = file_get_contents($jsonurl); $json_output = json_decode($json); var_dump ($json_output); // Returns NULL Basically, what i want to accomplish is to make a simple array from the first row values of the Json response. like this $array = {'john','John Handcock','[email protected]','2929292','blanc'} You guys are genius, I would appreciate your insight and help on this very much! Answer as "sberry2A" mentions bellow, the response is not valid Json, google offers the Zend Json library for this purpose, tho I decided to parse the tsv-excel version instead :)

• No styles / images on asp.Net MVC 2 application

  - by xenolf

  Greetings i have a little problem with my ASP MVC application. On my local development server everything works just fine but when i try to publish the application to an IIS 7.0 server it just displays plain pages without any styles / markups / images. I put all those things in the /Content/ subfolder but when i try to access that folder on the production server it just returns me a 404 not found error. I set the IIS server up with .Net 4.0 and followed the deployment guide on here: http://www.asp.net/learn/mvc/tutorial-08-cs.aspx All views / controllers / classes seem to work just fine, the only thing which does not is the content subfolder and i cant see why. Anyone got a suggestion what i could have overlooked or does anyone know that problem?

• Declaring data types in SQLite

  - by dan04

  I'm familiar with how type affinity works in SQLite: You can declare column types as anything you want, and all that matters is whether the type name contains "INT", "CHAR", "FLOA", etc. But is there a commonly-used convention on what type names to use? For example, if you have an integer column, is it better to distinguish between TINYINT, SMALLINT, MEDIUMINT, and BIGINT, or just declare everything as INTEGER? So far, I've been using the following: INTEGER REAL CHAR(n) -- for strings with a known fixed with VARCHAR(n) -- for strings with a known maximum width TEXT -- for all other strings BLOB BOOLEAN DATE -- string in "YYYY-MM-DD" format TIME -- string in "HH:MM:SS" format TIMESTAMP -- string in "YYYY-MM-DD HH:MM:SS" format (Note that the last three are contrary to the type affinity.)

• noweb dpp filter and latex not printing curly braces

  - by Dervin Thunk

  Hello. Well, this smells like a tumbleweed, but I will ask it anyway. Suppose you have a noweb file with some c# code. You also have the c++ pretty-print filter dpp. If you run the command noweave -filter ./dpp -x test.nw > csharp.tex on the file below, it will print everything except for the curly braces. Instead of them, I get an em-dash and a closing quotations marks (i.e. ?) in the dvi. The tex source looks fine... Any ideas? @ C\# test file <<test.c>>= while( (a[right] >= pivot) && (left < right) ) { right--; }

• jQuery and Canvas.toDataURL

  - by Jeff

  I'm working on a script, and a small part of that involves taking a canvas and converting it to a downloadable image. To do this, I do: var thumb_jpeg = thumbnail.toDataURL("image/jpeg"); $("#" + options.dest).attr('src',thumb_jpeg); ...where thumbnail is a canvas tag and options.dest is the name of an img id. This code works perfectly in Chrome, but when I try it in Firefox, Firebug throws up this error: Security error" code: "1000 var thumb_jpeg = thumbnail.toDataURL("image/jpeg"); I would link to the whole script, but everything is hosted on my computer. Does anyone have any idea what this might mean? Thanks! Jeff

• Using MS Moles with datacontext and stored procedures without using a Connection string.

  - by Brian

  I have just begun to work with MS Moles for testing and I have followed the idea/pattern in which jcollum(thanks) uses a Mole for a table in this stackoverflow question here. But I am having a problem as I do not want to have to pass a connection string when I use the datasource as such: using (TheDataContext dataContext = new TheDataContext(myConnectionString)) { dataContext.ExecuteStoredprocedure(value, ref ValueExists); } I really like the fact that I just need to mole the table and everything else is done for me. I realize I could just mole the ExecuteStoredProcedure method, but I am wondering if I could just somehow avoid the sql exception I am getting here when I do not pass in the connection string. Or, if I there is a better way to do this? Therefore, does anyone have a solution so that I can avoid placing in the connection string? Thanks in advance.

• bundle .NET dlls to run application in .NET-less machine?

  - by Camilo Martin

  AFAIK, ngen turns MSIL into native code (also reffered to as pre-JIT), however I never payed too much attention at it's startup performance impact. Ngen'd applications still require the .NET base class libraries (the runtime). Since the base class libraries have everything our .NET assemblies need (correct?) would it be possible to ship the framework's DLLs with my ngen'd application so that it does not require the runtime to be installed? (e.g., the scenario for most Windows XP machines) Oh, and please don't bother mentioning Remotesoft's Salamander Linker or Xenocode's Postbuild. They are not for my (and many's) current budget (and they seem to simply bundle the framework in a virtualized enviroinment, which means big download sizes and slow startup times I believe) EDIT: I know now, ngen doesn't do what I thought it did. But is it possible to bundle the .NET files with an application, without using a VM?

• Visual Assist X: curly braces are moving during refactoring

  - by overrider

  I use Visual Assist X, build from 05.01.2009, but the same problem occurred in the previous releases as well. (I run it on MSVS 2005) When I do some refactoring (like extracting a method), everything's fine, but all the curly braces move forward. For example, before refactoring the code looked like this: while (expr) { doSmth(); } After refactoring: while (expr) { doSmth(); } So, I need to move manually all the brackets. Sure, the problem is minor, but it becomes annoying when you do a lot of refactoring. Is it a bug or just default settings? So, does anyone know a workaround?

  I seem to have run into a bit of an issue. I am busy creating an app, and over the last few weeks setup my server to use Git, mod_wsgi to host this app. Since deploying it, everything seems to be running smoothly however, I had to go through all my files and insert the absolute url of the project to make sure it works fine. on my local machine from registration.models import UserRegistration on server from myapp.registration.models import UserRegistration Am I doing something wrong? And this has also caused an issue for me where I cannot access my django admin interface. All i get is this: Caught an exception while rendering: No module named registration Exception Value: Caught an exception while rendering: No module named registration As far as I am concerned my app has all the relevant urls, but it does not seem to work. Thank you in advance

• MinGW Doesn't Generate an Object File When Compiling

• Oracle .NET Provider DLL hell

  - by Pablo Santa Cruz

  I am currently developing on a Win7-32bits computer. Everything works fine. It's a ASP.NET application. I was able to use Microsoft's Oracle deprecated .NET provider to connect to Oracle (using 32 bit instant client) and also ODP.NET. No problems at all. Application runs fine. The problem comes when I deploy it to IIS7 on Windows 2008 Server 64bit computer. I can't get Microsoft's deprecated .NET provider or ODP.NET to work easily. Is there a straightforward way to use a 32bit based ODP.NET or Microsoft's Oracle deprecated .NET provider in Windows 2008 Server 64bits? DLL hell here! Thanks.

• Young people using Emacs?

  - by bigmonachus

  I am a college student that has fallen in love with Emacs. I have used IDEs in the past, and although features like Intellisense made the switch to Emacs very hard, I now think that Emacs is much more powerful, and features like Intellisense can be pretty closely matched by various modes depending on language (and I am not referring to M-/). I am happily writing Elisp code for everything that I need that isn't provided by modes or by Emacs itself and I love the way that it adapts and molds to my needs. However, I do think that its main disadvantage is the fact that it has a pretty steep learning curve and that most new programmers will not even begin to learn it out of many common misconceptions. So, I want to know the opinions of young people (or any person who didn't start using Emacs before there were IDEs) that are Emacs users. Just to get some reassurance that Emacs is not dead within our Eclipse-loving generation =). (Opinions of users of any other highly extensible editor like Jedit are also welcome)

• Java Timers - Functions called not completing!

  - by Matt Swanson

  So I have a TimerTask task calling a function onTimerComplete() in its run() onTimerComplete() looks something like this: private void onTimerComplete(){ myFunc1(); myFunc2(); } I make a Timer t and I schedule the TimerTask with t.schedule(task, 2000); The problem is, when the timer is up and the task runs my onTimerComplete() but that function does not finish. It runs myFunc1() but never finishes it nor does it ever call myFunc2() However, if I call onTimerComplete() directly, everything works. What's the deal here?

• My C#.NET application is running slower when the exe is located on the network

  - by leo

  Hi, My C#.NET application is running much slower when the exe is located on the network. And I'm talking about everything, even the graphical dispay is slower. For example: when a form is already loaded, if I unplug my network cable and minimize and maximize the window, it takes a very long time to redraw itself. I'm using framework .NET 3.5 SP1. Any idea on the cause? My hypothesis so far: I'm missing some options when building the app? my corporate antivirus checks more stuff because the exe is on the network the cache of Windows XP SP3 doesn't work the same way when the exe is on the network the server is a Novell server: maybe this does change something ? Thanks for your help! Leo
