  • How to handle javascript & css files across a site?

    - by Industrial
    Hi everybody, I have had some thoughts recently on how to handle shared javascript and css files across a web application. In a current web application that I am working on, I got quite a large number of different javascripts and css files that are placed in an folder on the server. Some of the files are reused, while others are not. In a production site, it's quite stupid to have a high number of HTTP requests and many kilobytes of unnecessary javascript and redundant css being loaded. The solution to that is of course to create one big bundled file per page that only contains the necessary information, which then is minimized and sent compressed (GZIP) to the client. There's no worries to create a bundle of javascript files and minimize them manually if you were going to do it once, but since the app is continuously maintained and things do change and develop, it quite soon becomes a headache to do this manually while pushing out new updates that features changes to javascripts and/or css files to production. What's a good approach to handle this? How do you handle this in your application?

  • .htaccess file on localhost throwing an error when using a Virtual Host config on my Localhost!!

    - by Chris
    I am trying to set-up my localhost development server. I have everything working but when I try to add an .htaccess it throws this error: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. I dont know exactly why this is, this is pretty much the exact same setup as the other developers machine, but when using my .htaccess file I get that error. Here is my .htaccess file (NOTE: They are commented because I left my site with this setup. It only lets me view the index page. Without this .htaccess file, I can navigate.): Options -indexes RewriteEngine On ErrorDocument 404 /404 RewriteRule ^battery/([^/]+)$ /browser/product?sku=BATTERY+$1&type=battery RewriteRule ^vehicles/([^/]+)/([^/]+)/([^/]+)/product([0-9]+)$ /browser/index.php?make=$1&model=$2&id=$3 [L,NC] RewriteRule ^vehicles/([^/]+)/([^/]+)/([^/]+)/([0-9]+)$ /browser/product.php?make=$1&model=$2&year=$3&id=$4 [L,NC] RewriteRule ^vehicles/([^/]+)/([^/]+)/([^/]+)$ /browser/index.php?make=$1&model=$2&year=$3 [L,NC] RewriteRule ^vehicles/([^/]+)/([^/]+)$ /browser/index.php?make=$1&model=$2 [L,NC] RewriteRule ^vehicles/([^/]+)$ /browser/index.php?make=$1 [L,NC] RewriteRule ^vehicles/$ /browser/index.php [L,NC] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^(.*)$ $1.php

  • Use `require()` with `node --eval`

  • Selective replication with CouchDB

    - by FRotthowe
    I'm currently evaluating possible solutions to the follwing problem: A set of data entries must be synchonized between multiple clients, where each client may only view (or even know about the existence of) a subset of the data. Each client "owns" some of the elements, and the decision who else can read or modify those elements may only be made by the owner. To complicate this situation even more, each element (and each element revision) must have an unique identifier that is equal for all clients. While the latter sounds like a perfect task for CouchDB (and a document based data model would fit my needs perfectly), I'm not sure if the authentication/authorization subsystem of CouchDB can handle these requirements: While it should be possible to restict write access using validation functions, there doesn't seem to be a way to authorize read access. All solutions I've found for this problem propose to route all CouchDB requests through a proxy (or an application layer) that handles authorization. So, the question is: Is it possible to implement an authorization layer that filters requests to the database so that access is granted only to documents that the requesting client has read access to and still use the replication mechanism of CouchDB? Simplified, this would be some kind of "selective replication" where only some of the documents, and not the whole database is replicated. I would also be thankful for directions to some detailed information about how replication works. The CouchDB wiki and even the "Definite Guide" Book are not too specific about that.

  • Configuration Error , Finding assembly after I swapped referenced dll out. Visual Studio 2003

    - by TampaRich
    Here is the situation. I had a clean build of my asp.net web application working. I then went into the bin folder under the web app and replaced two referenced dll's with two older version of the same dll's. (Same name etc.) After testing I replaced those dll's back to the new ones and now my application keeps throwing the configuration error === Pre-bind state information === LOG: DisplayName = xxxxx.xxxx.Personalization (Partial) LOG: Appbase = file:///c:/inetpub/wwwroot/appname LOG: Initial PrivatePath = bin Calling assembly : (Unknown). LOG: Policy not being applied to reference at this time (private, custom, partial, or location-based assembly bind). I found this issue on the web and tried all the solutions to it but nothing worked. I then went into all my projects that it references under the solution and cleared out the bin/debug folder in each, I cleared out the obj folder under each and also deleted the temporary files associated with the application. I rebuilt it and it still will not work due to this error Not sure what is causing this or how to fix this issue. I have tried restarting IIS, stopping index services which was said to be a known issue. This is .net framework 1.1 app and visual studio 2003 Any suggestions would be great. Thanks.

  • Which web solution should I use for my project?

    - by BenIOs
    I'm going to create a fairly large (from my point of view anyway) web project with a friend. We will create a site with roads and other road related info. Our calculations is that we will have around 100k items in our database. Each item will contain some information like location, name etc. (about 30 thing each). We are counting on having a few hundred thousand unique visitors per month. The 100k items and their locations (that will be searchable) will be the main part of the page but we will also have some articles, comments, news and later on some more social functions (accounts, forums, picture uploads etc.). We were going to use Google AppEngine to develop our project since it is really scalable and free (at least for a while). But I'm actually starting to doubt that AppEngine is right for us. It seems to be for webbapps and not sites like ours. Which system (language/framework etc.) would you guys recommend us to use? It doesn't really mater if we know the language since before (we like learning new stuff) but it would be good if it's something that is future proof.

  • How to check user input for correct formatting

    - by Arcadian
    This is what i've come up with so far private void CheckFormatting() { StringReader objReaderf = new StringReader(txtInput.Text); List<String> formatTextList = new List<String>(); do { formatTextList.Add(objReaderf.ReadLine()); } while (objReaderf.Peek() != -1); objReaderf.Close(); for (int i = 0; i < formatTextList.Count; i++) { } } What it is designed to do is check that the user has entered their information in this format Gxx:xx:xx:xx JGxx where "x" can be any integer. As you can see the user inputs their data into a multi-line textbox. i then take that data and enter it into a list. the next part is where i'm stuck. i create a for loop to go through the list line by line, but i guess i will also need to go through each line character by character. How do i do this? or is there a faster way of doing it? thanks in advance

  • md5_file() not working with IP addresses?

    - by Rob
    Here is my code relating to the question: $theurl = trim($_POST['url']); $md5file = md5_file($theurl); if ($md5file != '96a0cec80eb773687ca28840ecc67ca1') { echo 'Hash doesn\'t match. Incorrect file. Reupload it and try again'; When I run this script, it doesn't even output an error. It just stops. It loads for a bit, and then it just stops. Further down the script I implement it again, and it fails here, too: while($row=mysql_fetch_array($execquery, MYSQL_ASSOC)){ $hash = @md5_file($row['url']); $url = $row['url']; mysql_query("UPDATE urls SET hash='" . $hash . "' WHERE url='" . $url . "'") or die("MYSQL is indeed gay: ".mysql_error()); if ($hash != '96a0cec80eb773687ca28840ecc67ca1'){ $status = 'down'; }else{ $status = 'up'; } mysql_query("UPDATE urls SET status='" . $status . "' WHERE url='" . $url . "'") or die("MYSQL is indeed gay: ".mysql_error()); } And it checks all the URL's just fine, until it gets to one with an IP instead of a domain, such as: http://188.72.215.195/config.php In which, again, the script then just loads for a bit, and then stops. Any help would be much appreciated, if you need any more information just ask.

  • Logic: Best way to sample & count bytes of a 100MB+ file

    - by Jami
    Let's say I have this 170mb file (roughly 180 million bytes). What I need to do is to create a table that lists: all 4096 byte combinations found [column 'bytes'], and the number of times each byte combination appeared in it [column 'occurrences'] Assume two things: I can save data very fast, but I can update my saved data very slow. How should I sample the file and save the needed information? Here're some suggestions that are (extremely) slow: Go through each 4096 byte combinations in the file, save each data, but search the table first for existing combinations and update it's values. this is unbelievably slow Go through each 4096 byte combinations in the file, save until 1 million rows of data in a temporary table. Go through that table and fix the entries (combine repeating byte combinations), then copy to the big table. Repeat going through another 1 million rows of data and repeat the process. this is faster by a bit, but still unbelievably slow This is kind of like taking the statistics of the file. NOTE: I know that sampling the file can generate tons of data (around 22Gb from experience), and I know that any solution posted would take a bit of time to finish. I need the most efficient saving process

  • Merging multiple docx files to one

    - by coding
    I am developing a desktop application in C#. I have coded a function to merge multiple docx files but it does not work as expected. I don't get the content exactly as how it was in the source files. A few blank lines are added in between. The content extends to the next pages, header and footer information is lost, page margins gets changed, etc.. How can I concatenate docs as it is without and change in it.Any suggestions will be helpful. This is my code. public bool CombineDocx(string[] filesToMerge, string destFilepath) { Application wordApp = null; Document wordDoc = null; object outputFile = destFilepath; object missing = Type.Missing; object pageBreak = WdBreakType.wdPageBreak; try { wordApp = new Application { DisplayAlerts = WdAlertLevel.wdAlertsNone, Visible = false }; wordDoc = wordApp.Documents.Add(ref missing, ref missing, ref missing, ref missing); Selection selection = wordApp.Selection; foreach (string file in filesToMerge) { selection.InsertFile(file, ref missing, ref missing, ref missing, ref missing); selection.InsertBreak(ref pageBreak); } wordDoc.SaveAs( ref outputFile, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); return true; } catch (Exception ex) { Msg.Log(ex); return false; } finally { if (wordDoc != null) { wordDoc.Close(); } if (wordApp != null) { wordApp.DisplayAlerts = WdAlertLevel.wdAlertsAll; wordApp.Quit(); Marshal.FinalReleaseComObject(wordApp); } } }

  • Sending variable data from one of two text boxes to javascript

    - by Enyalius
    Greetings, all! I am fairly new to JS (my background is in C++, enterprise languages like assembly and COBOL, and some light .NET), so I was wondering if I could get some advice regarding how to send variable information from one of two text boxes to some javascript and then have the JS do some basic checks and such. Here's the pseudocode for what I am trying to do: <form = webForm> <p> _____________ textboxPeople| searchIcon //a text box to search an online phonebook at my company. ------------- //It has a little "magnifying glass" icon to search //(onClick), but I would also like them to be able to //search by hitting the "enter" key on their keyboards. </p> <p> _____________ texboxIntranet| searchIcon //Same as above search textbox, but this one is used if ------------- //the user wishes to search my corporate intranet site. </form> So ends the front-facing basic form that I would like to use. Now, onClick or onEnter, I would like the form to pass the contents of the text box used as well as an identifier such as "People" or "Intranet," depending on which box is used, to some basic JS on the back end: begin JavaScript: if(identifier = 'People') fire peopleSearch(); else if(identifier = 'Intranet') fire intranetSearch(); function peopleSearch() { http://phonebook.corporate.com/query=submittedValue //This will take the person //that the user submitted in the form and //place it at the end of a URL, after which //it will open said complete URL in the //same window. } function intranetSearch() { http://intranet.corporate.com/query=submittedValue //This will function in the //same way as the people search function. } end JavaScript Any thoughts/suggestions would be greatly appreciated. Thank you all in advance!

  • Response time increasing (worsening) over time with consistent load

    - by NJ
    Ok. I know I don't have a lot of information. That is, essentially, the reason for my question. I am building a game using Flash/Flex and Rails on the back-end. Communication between the two is via WebORB. Here is what is happening. When I start the client an operation calls the server every 60 seconds (not much, right?) which results in two database SELECTS and an UPDATE and a resulting response to the client. This repeats every 60 seconds. I deployed a test version on heroku and NewRelic's RPM told me that response time degraded over time. One client with one task every 60 seconds. Over several hours the response time drifted from 150ms to over 900ms in response time. I have been able to reproduce this in my development environment (my Macbook Pro) so it isn't a problem on Heroku's side. I am not doing anything sophisticated (by design) in the server app. An action gets called, gets some data from the database, performs an AR update and then returns a response. No caching, etc. Any thoughts? Anyone? I'd really appreciate it.

  • BlackBerry 5.0 causing full menu to show on navigationClick

    - by jwadsack
    I have a BlackBerry app that is built for 4.5.x SDK. The first page of the app shows a list of fields and each field can be highlighted and clicked. The click action shows a new view with additional information about the field. This all works fine in 4.5, 4.6 and 4.7 and on the sim with 5.0. On a real 9000 running 5.0, when clicking the trackball on an item in the list, the full menu is showing rather than the click event getting consumed (or even fired) for the field. The view is derived from MainScreen and looks something like this: public class ListView extends MainScreen { public ItemCollection list = new ItemCollection; protected void sublayout( int maxWidth, int maxHeight ) { int i = 1; while(( item == (Item)list.nextElement()) != null) { ItemField field = new ItemField(item, i++); add(field); } } } This class does not consume navigationClick, but shouldn't need to, right? The field class does consume navigationClick event: public class ItemField extends Field { protected boolean navigationClick(int status, int time) { controller.showDeal(item.id, Session.current); return true; } } Is there something that changed in 5.0 that I need to add to have this app work the same for all platforms?

  • Best practices for "search data class" in ASP.NET MVC

    - by Tim Ridgely
    Hi everybody, I'm hoping this isn't too subjective, but I'm new to ASP.NET MVC and I'm trying to figure out how others may have solved similar problems. Basically, I have two entities, Customers and Orders. A customer has many orders; an order belongs to exactly one customer. I'm making an Order Search feature that should allow a user to search for orders based on order or customer information. Pretty straightforward, I think. I've read in other posts that the search controller should use GET, but I think it makes more sense to use POST because of the large number of search params. I'm using Entity Framework to create my models, and that's in a separate class library project and namespace. This article talks about using binding instead of Request.Form to get at the POST data. Would it make decent sense to make a class to hold all the search data that could be materialized by the magic model binding? Otherwise I'd just be poking through the FormCollection to pull out particular values, which might be fine. Where would you recommend making such a class?

  • Unsure how to come up with a good design

    - by Mewzer
    Hello there, I am having trouble coming up with a good design for a group of classes and was hoping that someone could give me some guidance on best practices. I have kept the classes and member functions generic to make the problem simpler. Essentially, I have three classes (lets call them A, B, and C) as follows: class A { ... int GetX( void ) const { return x; }; int GetY( void ) const { return y; }; private: B b; // NOTE: A "has-a" B int x; int y; }; class B { ... void SetZ( int value ) { z = value }; private: int z; C c; // NOTE: B "has-a" C }; class C { private: ... void DoSomething(int x, int y){ ... }; void DoSomethingElse( int z ){ ... }; }; My problem is as follows: Class A uses its member variables "x" and "y" a lot internally. Class B uses its member variable "z" a lot internally. Class B needs to call C::DoSomething(), but C::DoSomething() needs the values of X and Y in class A passed in as arguments. C::DoSomethingElse() is called from say another class (e.g. D), but it needs to invoke SetZ() in class B!. As you can see, it is a bit of a mess as all the classes need information from one another!. Are there any design patterns I can use?. Any ideas would be much appreciated ....

  • Generating HTML Programmatically in C#, Targeting Printed Reports

    - by John Passaniti
    I've taken over a C# (2.0) code base that has the ability to print information. The code to do this is insanely tedious. Elements are drawn onto each page, with magic constants representing positioning. I imagine the programmer sitting with a ruler, designing each page by measuring and typing in the positions. And yes, one could certainly come up with some nice abstractions to make this approach rational. But I am looking at a different method. The idea is that I'll replace the current code that prints with code that generates static HTML pages, saves them to a file, and then launches the web browser on that file. The most obvious benefit is that I don't have to deal with formatting-- I can let the web browser do that for me with tags and CSS. So what I am looking for is a very lightweight set of classes that I can use to help generate HTML. I don't need anything as heavyweight as HTMLTextWriter. What I'm looking for is something to avoid fragments like this: String.Format("<tr><td>{0}</td><td>{1}</td></tr>", foo, bar); And instead take have this kind of feel: ... table(). tr(). td(foo). td(bar) Or something like that. I've seen lightweight classes like that for other languages but can't find the equivalent (or better) for C#. I can certainly write it myself, but I'm a firm believer in not reinventing wheels. Know anything like this? Know anything better than this?

  • Code thinks Datagrid footer textbox is empty...

    - by The Sheek Geek
    Hello All, I am working on an .net (C#) web application. Recently a defect came my way that stated that when two users were logged into the application at the same time they both could not update values without one refreshing the page. When I looked into the issue I discovered that the author of the code has used static datasets. I changed the datasets to not be static and everything works great. However, This issue spans many pages in the application and I must fix it everywhere. On some of these pages the application uses datasets to bind data to datagrids. The datagrids are populated with the information in the dataset and the footer contains some textboxes and an add button to add extra rows. Here is where the problem starts: When the page was using static datasets and the user attempted to add a row through the interface everything worked fine. However, when I changed it to use datasets that were not static (they are loaded every time the page loads) and the user attempts to add a row, the code thinks that the textbox is empty (discovered when debugging even though I can see the text that I entered) and empty field validation fails and a message is displayed. Can someone please tell me why on Earth this is happening? Why does it see the text when the dataset is static (the dataset NEVER populates the foot row) and not see the text when it is not static? Some insight would be awesome! Thanks in advance!

  • Python server open all ports

    - by user1670178
    I am trying to open all ports using this code, why can I not create a loop to perform this function? http://www.kellbot.com/2010/02/tutorial-writing-a-tcp-server-in-python/ #!/usr/bin/python # This is server.py file ##server.py from socket import * #import the socket library n=1025 while n<1050: ##let's set up some constants HOST = '' #we are the host PORT = n #arbitrary port not currently in use ADDR = (HOST,PORT) #we need a tuple for the address BUFSIZE = 4096 #reasonably sized buffer for data ## now we create a new socket object (serv) ## see the python docs for more information on the socket types/flags serv = socket( AF_INET,SOCK_STREAM) ##bind our socket to the address serv.bind((ADDR)) #the double parens are to create a tuple with one element serv.listen(5) #5 is the maximum number of queued connections we'll allow serv = socket( AF_INET,SOCK_STREAM) ##bind our socket to the address serv.bind((ADDR)) #the double parens are to create a tuple with one element serv.listen(5) #5 is the maximum number of queued connections we'll allow print 'listening...' n=n+1 conn,addr = serv.accept() #accept the connection print '...connected!' conn.send('TEST') conn.close() How do I make this work so that I can specify input range and have the server open all ports up to 65535? #!/usr/bin/python # This is server.py file from socket import * #import the socket library startingPort=input("\nPlease enter starting port: ") startingPort=int(startingPort) #print startingPort def connection(): ## let's set up some constants HOST = '' #we are the host PORT = startingPort #arbitrary port not currently in use ADDR = (HOST,PORT) #we need a tuple for the address BUFSIZE = 4096 #reasonably sized buffer for data def socketObject(): ## now we create a new socket object (serv) serv = socket( AF_INET,SOCK_STREAM) def bind(): ## bind our socket to the address serv = socket( AF_INET,SOCK_STREAM) serv.bind((ADDR)) #the double parens are to create a tuple with one element serv.listen(5) #5 is the maximum number of queued connections we'll allow serv = socket( AF_INET,SOCK_STREAM) print 'listening...' def accept(): conn,addr = serv.accept() #accept the connection print '...connected!' conn.send('TEST') def close(): conn.close() ## Main while startingPort<65535: connection() socketObject() bind() accept() startingPort=startingPort+1

  • Properly handling NSURLConnection errors

    - by Cal S
    Hi, I have a simple form interface set up that send username and password information to a server: (working) NSString *postData = [NSString stringWithFormat:@"user=%@&pass=%@",[self urlEncodeValue:sysUsername],[self urlEncodeValue:password]]; NSLog(@"Post data -> %@", postData); /// NSData* postVariables = [postData dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]; NSMutableURLRequest* request = [[[NSMutableURLRequest alloc] init] autorelease]; NSString* postLength = [NSString stringWithFormat:@"%d", [postVariables length]]; NSURL* postUrl = [NSURL URLWithString:@"http://localhost/~csmith/cocoa/test.php"]; [request setURL:postUrl]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody: postVariables]; NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:NULL error:NULL]; NSLog(@"Post data SENT & returned -> %@", returnData); How do I handle connection errors such as no internet connection, firewall, etc. Also, does this method use the system-wide proxy settings? Many of my users are behind a proxy. Thanks a lot!

  • Making firefox refresh images faster

    - by Earlz
    I have a thing I'm doing where I need a webpage to stream a series of images from the local client computer. I have a very simple run here: http://jsbin.com/idowi/34 The code is extremely simple setTimeout ( "refreshImage()", 100 ); function refreshImage(){ var date = new Date() var ticks = date.getTime() $('#image').attr('src','http://127.0.0.1:2723/signature?'+ticks.toString()); setTimeout ("refreshImage()", 100 ); } Basically I have a signature pad being used on the client machine. We want for the signature to show up in the web page and for them to see themselves signing it within the web page(the pad does not have an LCD to show it to them right there). So I setup a simple local HTTP server which grabs an image of what the current state of the signature pad looks like and it gets sent to the browser. This has no problems in any browser(tested in IE7, 8, and Chrome) but Firefox where it is extremely laggy and jumpy and doesn't keep with the 10 FPS rate. Does anyone have any ideas on how to fix this? I've tried creating very simple double buffering in javascript but that just made things worse. Also for a bit more information it seems that Firefox is executing the javascript at the correct framerate as on the server the requests are coming in at a constant speed. But the images are only refreshed inconsistently ranging from 5 times per second all the way down to 0 times per second(taking 2 seconds to do a refresh) Also I have tried using different image formats all with the same results. The formats I've tried include bitmaps, PNGs, and GIFs (GIFs caused a minor problem in Chrome with flicker though) Could it be possible that Firefox is somehow caching my images causing a slight lag? I send these headers though: Pragma-directive: no-cache Cache-directive: no-cache Cache-control: no-cache Pragma: no-cache Expires: 0

  • Installing Image_Graph and using with BASE

    - by PPowerHouseK
    Hello all, I have Windows 7 with the latest XAMPP installation. I configured BASE to work, for the most part. My problem is that in BASE, when I click on the graph alerts button, I get this error: Error loading the Graphing library: Check your Pear::Image_Graph installation! * Image_Graph can be found here:at http://pear.veggerby.dk/. Without this library no graphing operations can be performed. * Make sure PEAR libraries can be found by php at all: pear config-show | grep "PEAR directory" PEAR directory php_dir /usr/share/pear This path must be part of the include path of php (cf. /etc/php.ini): php -i | grep "include_path" include_path => .:/usr/share/pear:/usr/share/php => .:/usr/share/pear:/usr/share/php</code> I think it may have to do with the include path of the php.ini so here is what it currently says: ;;;;;;;;;;;;;;;;;;;;;;;;; ; Paths and Directories ; ;;;;;;;;;;;;;;;;;;;;;;;;; ; UNIX: "/path1:/path2" ;include_path = ".:/php/includes" ; ; Windows: "\path1;\path2" ;include_path = ".;c:\php\includes" ; ; PHP's default setting for include_path is ".;/path/to/php/pear" ; http://php.net/include-path include_path = ".;C:\xampp\php\PEAR" I am really at a loss as to how to resolve this. I searched for a while for some documentation but most referred to installing on ubuntu. I don't know any pear or php, so if you know how to fix this please explain thoroughly. I am willing to supply as much information as needed.
