  • LighTPD and PHP not working if outside of LightTPD folder

    - by Marco83
    I need to set up a simple web server with PHP on Windows XP that a number of different people will use for local testing. I'm using LightTPD 1.4.30-4-IPv6-Win32-SSL and PHP 5.2. So far I've created this folder structure: tools/ LightTPD/ htdocs/ PHP/ I set up PHP as CGI and the document root as server_root + "/htdocs". It works fine (well, it's slow but I don't want to bother with FastCGI for now :) ). My problem is when I try to put the htdocs outside of LightTPD folder, like this: htdocs/ tools/ LightTPD/ PHP/ I update the document root to server_root + "/../../htdocs" and while static HTML pages work fine, PHP pages stop working (they return a "No input file specified"). I literally just change the document root, I didn't change anything in the php.ini or anywhere else. Please also note that I left all doc_root, user_dir and cgi.force_redirect to the default values in php.ini, and it works when htdocs is inside LightTPD, but not when I move it ouside. Any idea of why it's breaking?? Here's my lightTPD.conf: server.modules = ( "mod_access", "mod_accesslog", "mod_alias", "mod_cgi", "mod_status", ) include "variables.conf" include "mimetype.conf" # THIS WORKS server.document-root = server_root + "/htdocs" # THIS DOESN'T #server.document-root = server_root + "/../../htdocs" server.upload-dirs = ( temp_dir ) index-file.names = ( "index.php", "index.pl", "index.cgi", "index.cml", "index.html", "index.htm", "default.htm" ) server.event-handler = "libev" url.access-deny = ( "~", ".inc" ) $HTTP["url"] =~ "\.pdf$" { server.range-requests = "disable" } static-file.exclude-extensions = ( ".php", ".pl", ".cgi" ) server.errorlog = server_root + "/logs/error.log" ######### Options that are good to be but not neccesary to be changed ####### dir-listing.activate = "enable" #### CGI module cgi.assign = ( ".php" => server_root + "/../PHP/php-cgi.exe" ) status.status-url = "/server-status" status.config-url = "/server-config"

  • Windows 7 doesn't start anymore

    - by 0xFF
    I've experienced some BSOD on windows 7 RC, and some freezing when startup, but today was big surprise, it doesn't start anymore. I tried to start on safe mode and no results too, it shows the starting animation, then a blue screen for less than a second and turns off immediately. The only thing I remember did today is update flash player under Firefox, then chrome stopped working even after logging off, and once restarting, it doesn't start anymore. Anyone experienced the same issue? any hints? [EDIT 3] Solved : Windows 7 have a very smart repair strategy, it works automatically, and it tried every possible fix, what fixed my problem was the system restore to a previous date, all this happened automatically. [EDIT2] these are the last lines in the ntbtlog.txt file Did not load driver \SystemRoot\System32\drivers\vga.sys Loaded driver \SystemRoot\System32\Drivers\NDProxy.SYS Did not load driver \SystemRoot\System32\Drivers\NDProxy.SYS Did not load driver \SystemRoot\System32\Drivers\NDProxy.SYS Did not load driver \SystemRoot\System32\Drivers\NDProxy.SYS Did not load driver \SystemRoot\System32\Drivers\NDProxy.SYS Loaded driver \SystemRoot\system32\drivers\CHDRT32.sys Loaded driver \SystemRoot\system32\DRIVERS\VSTAZL3.SYS Loaded driver \SystemRoot\system32\DRIVERS\VSTDPV3.SYS Loaded driver \SystemRoot\system32\DRIVERS\VSTCNXT3.SYS Loaded driver \SystemRoot\system32\drivers\modem.sys Loaded driver \SystemRoot\system32\DRIVERS\usbccgp.sys Loaded driver \SystemRoot\System32\Drivers\usbvideo.sys [edit] this is the BSOD I get : http://twitpic.com/i87cx Thank you.

  • Game Asset Management

    - by user964123
    I am making my first small mobile game in C# XNA. Lets say I have 3 screens, the main menu, options and game screen. A single game session usually lasts for 1 min, so the user will alternate frequently between the main menu and game screen. Therefore, once I load the textures for either screen, I want to keep them in memory to avoid frequent reloading. Both screens share some assets like their background textures, but differ in others. The first solution I came up with is making 2 texture factory classes, MainScreenAssetFactory and GameScreenAssetFactory, each with their own content manager, and ill store them in a globally accessible point so that they persist after either screen is destroyed. There is also a OptionsScreenAssetFactory, but that I dont want to cache it since the options screen is rarely visited. A typical Factory would look something like this public class MainScreenAssetFactory { private readonly ContentManager contentManager; public MainScreenAssetFactory(IServiceProvider serviceProvider, string rootDirectory) { contentManager = new ContentManager(serviceProvider) { RootDirectory = rootDirectory }; } public Texture2D ListElementBackground { get { return return contentManager.Load<Texture2D>("UserTab"); } } public Texture2D ListElementBulletPoint { get { return return contentManager.Load<Texture2D>("TabIcon"); } } public Texture2D LoggedOutUser { get { return return contentManager.Load<Texture2D>("LoggedOutUser"); } } } Since both Main, Options and Game Screen share some common resources, instead of loading them more than once, I created another class CommonAssetTexFactory which holds the common stuff and stays in-memory during the app lifetime. For example, this class gets passed to the options screen when it is created. However, given my small game with its few assets, I am already finding this solution cumbersome and inflexible. Changing anything would require looking to see if its already in the common factory, and if not, modifying existing factories and so on. And this is just considering textures currently, i didnt add sound files yet. I cant imagine bigger games with thousands of resources using this approach. A better idea must exist. Would someone please enlighten me?

  • Choosing the Database Solution for Large Data Application

    - by GµårÐïåñ
    I have been tasked to write an application that will be a combination of document and inventory management in VB.net which will be used to store document images in TIFF, PDF, XPS, TXT, DOC, PPT and so on as binary data that can be retrieved for viewing, printing, and possible OCR to be searchable as well along with meta data such as sender, recipient, type of document, date, source, etc. So the table would probably be something like: DOC_NAME, DOC_DATE, NOTES, ... DOC_BINARY (where the actual document will be put inside) What my concern is finding a database solution that will not become unstable due to size restrictions, records limitations and performance. Some of the options are MS_SQL, SQL Express, SQLite, mySQL, and Access. Now I can pretty much eliminate Access right off the bat as it is just too limiting and not scalable. I can further eliminate SQL Express because of the 2 GB limit and again scalability. So that leaves me with MS_SQL, SQLite and mySQL (although if anyone has other options they think would be good as well, please feel free to share them, by no means am I set on these only). So this brings me to what you guys think is the best option for what I have described. The goal is that the data is all in one place (a single file) that will make backup and portability easier. For small volume usage, pretty much any solution will hold for a while, but my goal is to think ahead and make sure its able to withstand heavy large volume usage as well. Another consideration is also the interoperability with .NET and stability of such code to avoid errors and memory leaks. Your feedback would be greatly appreciated.

  • How can I remove unwanted cropped pages from Acrobat

    - by Servant
    Executing the crop command in Acrobat from a 3000pt * 2000pt document to 1500pt*1800pt only hides the document outside of the new boundaries but the original document still remains without change; if anyone uses the touch-up tool and moves the content, all "hidden" information outside the cropped page may appear again by dragging it into view. The page acting as a window (or a mask) to display the 3000pt * 2000pt. I am wondering if there is a solution to crop permanently the document without reprinting it again into PDF file? Please find pictures attached: http://i.stack.imgur.com/5JTPg.png http://i.stack.imgur.com/HPokv.png

  • I can not cd "LaunchAgents" on macbook

    - by why
    after installing mongdb on my macbook-pro, it tells me: If this is your first install, automatically load on login with: cp /usr/local/Cellar/mongodb/1.6.3-x86_64/org.mongodb.mongod.plist ~/Library/LaunchAgents launchctl load -w ~/Library/LaunchAgents/org.mongodb.mongod.plist If this is an upgrade and you already have the org.mongodb.mongod.plist loaded: launchctl unload -w ~/Library/LaunchAgents/org.mongodb.mongod.plist cp /usr/local/Cellar/mongodb/1.6.3-x86_64/org.mongodb.mongod.plist ~/Library/LaunchAgents launchctl load -w ~/Library/LaunchAgents/org.mongodb.mongod.plist Or start it manually: mongod run --config /usr/local/Cellar/mongodb/1.6.3-x86_64/mongod.conf but after i copy org.mongodb.mongod.plist to ~/Library/LaunchAgents, it tells me launchctl load -w ~/Library/LaunchAgents/org.mongodb.mongod.plist launchctl: Couldn't stat("/Users/liuqiang/Library/LaunchAgents/org.mongodb.mongod.plist"): Not a directory and also i can not cd "~/Library/LaunchAgents", but i can ls the directory! "~/Library/LaunchAgents" is a strange directory in mac.

  • Siege - running a stress test benchmark

    - by morgoth84
    I need to do a benchmark test of a HTTPS server using Siege, to see how it behaves under massive load. I'm initiating tests from another machine which is quite powerful and it is connected to the same physical switch the server is connected on. But when I initiate a test, I can't get it to make more than 170 requests per second. With this load the server's CPU usage is at 15-20% and the average response time for a request is approx. 0.03 seconds. Load of the client machine is approx. at 10%. So, I gradually increase the number of users in Siege (the number of worker threads) and request rate linearly increases up to 170 reqs/sec, but it never gets over it. No matter how many more worker threads I start, the load on the server is never more than 20% (and the client's load also doesn't increase any more). How can I overcome this? I've googled a bit and found out that after a request is completed, a socket associated with one ephermal port remains in WAIT_TIME state for some time during which it can't be reused. I tried to overcome this by doing these things: sysctl -w net.ipv4.ip_local_port_range="1024 65535" echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle Oh, and the client machine is a Linux (RedHat, I think, but I'm not sure). Any help would be appreciated.

  • PDF form (not) saving

    - by gregseth
    I've created a form in a PDF with Adobe Acrobat Pro. When empy, I want to use it as a template which the user opens, fills in, and saves as a copy to preserve the blank state of the template. Here's the trick : I found both ways to make the document read only - the user can't save the form value, only print them make the document writeable, but in this case the document acting as a template can be modified too. Any ideas? Thanks.

  • MS Excel: Can I link images using a relative path?

    - by Port Islander 2009
    I am working on an MS Excel document that contains a lot of (around 200) images. They are currently saved within the document, so the file becomes huge and working gets very slow. Linking the pictures without saving them works very well - I now have the Excel document and a folder "pictures" next to it that contains all my image files. However, when I move the document and the folder to a new location, all my pictures disappear. This seems to be because Excel saves the link information as absolute paths. (Update: Actually, according to this thread, Excel stores the link information as relative paths as well. Now I really don't know why my links break down..) Is there a convenient way to save them as relative paths or have Excel automatically update the path information? Update: It's important that the images get displayed on the sheet and can be printed. I am working with Microsoft Excel for Mac 2008 and 2011. I really appreciate your help.

  • Apache 2 settings for high traffic website

    - by Harry
    I'm having problems with the load on my website. It's an amazon ec2 server with 15Gb ram and 4 CPUs behind an LB. apachetop says I'm getting around 80 reqs per second which seems really low for this kind of server and the load ( given by top ) is usually around 15 but does increase to about 150 in 24 hrs. I'm seeing about 100 active apache processes at any time. Apache is in prefork mode. Mysql is used very little on the server and there are almost no static files. Here are my Apache settings: Timeout 20 KeepAlive Off MaxKeepAliveRequests 0 KeepAliveTimeout 3 <IfModule mpm_prefork_module> StartServers 40 MinSpareServers 25 MaxSpareServers 40 ServerLimit 400 MaxClients 400 MaxRequestsPerChild 4 </IfModule> Can anyone advise on how to tweak the settings? Thanx! Edit: The config was gotten by trial and error. Any and I mean by a number, change to these lines make the load skyrocket in like 5 minutes. It literally jumps to like 200-300 in a matter of minutes. Especially MaxRequestsPerChild. I've tried with 10, 15, 100, 1000 and the load just skyrockets. About php - there are actually only a few php files which aren't really that expensive at all. They just spit some simple stuff out. If I turn on KeepAlive load also goes to space..

  • Creating MS Word 2010 Relative Links?

    - by leeand00
    Okay here is what I've tried so far for creating relative links in my MS Word Documents. In my document from the ribbon I select the File tab. I then select Info from the side bar. Click the properties drop down from the right hand column. (a bit difficult to find initially, since it looks like text not a drop down, but it's there). Click Advanced Properties The <document-name>.docx Properties Dialog Appears I enter .\ to specify that I want a relative path for the links in my document. I click OK. I go back into my document select some text and attempt to make a link out of it clicking the Insert tab of the ribbon, and then clicking Hyperlink. I then select a document from the current folder, and strip the full path from it, leaving just the name of the .docx file to which I wish to link. Then I click OK. The link appears, I try to click it using Ctrl+Click. I am informed that the address of the site is not valid. Check the address and try again. What could I possibly be doing wrong here? I just want a relative link. It's so easy in to do this in HTML.

  • ASP.NET, IS7 and IE8 caching?

    - by jdege
    We're suddenly having problems with some of our sites having old versions of .css and .js files show up in the browser. Generally, these problems go away, when the user clears cache in the browser. Is there something we can do either in the code or in IIS7, to convince the browser to not used the cached files? In our weirdest case, we have one customer whose users hit our site, and get an old version of a js file. They clear cache, load the page, get the current version, and the page runs fine. Then they load the file again, and suddenly have the old version, again. Any ideas as to how that might be happening? I can think of three: The browser is somehow holding on to the old version, when we clear cache, and is putting it back in the cache, before the second page load. One of our servers has an old version of the file, and while the first page load after a clear cache pulls it from one of the servers with the current version, second and subsequent page loads pull it from the server that has the old version. The first load after a clear cache goes straight to our servers, while subsequent loads pull the file from the cache on the customer's web proxy. I have to say, all three of those scenarios seem outlandishly unlikely, but it's a repeatable behavior. Any ideas?

  • Drawing chunks, and positioning the camera

    - by Troubleshoot
    I've seen many questions and answers regarding how to draw tiled maps but I can't really get my head around it. Many answers suggest either loading the visible part of the map, or loading and unloading chunks of the map. I've decided the best option would be to load chunks, but I'm slightly confused as to how this would be implemented. Currently I'm loading the full map to a 2D array of buffered images, then drawing it every time repaint is called. Q1: If I were to load chunks of the map, would I load the map as a whole then draw the necessary chunk(s), or load & unload the chunks as the player moves along, and if so, how? My second question regards the camera. I want the player to be in the centre of the X axis and the camera to follow it. I've thought of drawing everything in relation to the map and calculating the position of the camera in relation to the players coordinates on the map. So, to calculate the camera's X position I understand that I should use cameraX = playerX - (canvasWidth/2), but how should I calculate the Y position? I want the camera to only move up when the player reaches cameraHeight/2 but to move down when the player reaches 3/4(cameraHeight). Q2: Should I check for this in the same way I check for collision, and move the camera relative to the movement of the player until the player stops moving, or am I thinking about it in the wrong way?

  • Google Maps API v3: Turning user input coordinates to latlng?

    - by Leventhan
    I'm new with Google Maps. I'm trying to turn coordinates a user inputs to move a marker I have on my map to those coordinates. For instance, if the user inputs 50.75, 74.1 the marker will pan to that coordinate. Unfortunately, I couldn't get it to work. Here's my function: function moveMarker() { var Markerloc = document.getElementById("Markerloc").value; var newLatlng = new google.maps.LatLng(Markerloc); marker.setPosition(newLatLng) } Here's my HTML code: <input type="text" id= "Markerloc" value="Paste your coordinates" /> <input type="button" onclick="moveMarker()" value="Update Marker"> EDIT: I thought that'd fix it, but somehow, it still doesn't work. Here's my code: <script type="text/javascript"> var map; var zoomLevel; function initialize(){ var myLatlng = new google.maps.LatLng(40.65, -74); var myOptions = { zoom: 2, center: myLatlng, mapTypeId: google.maps.MapTypeId.ROADMAP, } var map = new google.maps.Map(document.getElementById('map_canvas'), myOptions); var zoomLevel = map.getZoom(); var marker = new google.maps.Marker({ position: myLatlng, map: map, draggable: true }); // Update current position info. updateMarkerPosition(myLatlng); // Add dragging event listeners. google.maps.event.addListener(marker, 'dragstart', function() { updateMarkerAddress('Dragging...'); }); google.maps.event.addListener (map, 'zoom_changed', function() { updateZoomLevel(map.getZoom()); }); google.maps.event.addListener(marker, 'drag', function() { updateMarkerStatus('Dragging...'); updateMarkerPosition(marker.getPosition()); }); google.maps.event.addListener(marker, 'dragend', function() { updateMarkerStatus('Drag ended'); geocodePosition(marker.getPosition()); }); }; var geocoder = new google.maps.Geocoder(); function geocodePosition(pos) { geocoder.geocode({ latLng: pos }, function(responses) { if (responses && responses.length > 0) { updateMarkerAddress(responses[0].formatted_address); } else { updateMarkerAddress('Cannot determine address at this location.'); } }); } function updateZoomLevel(zoomLevel){ document.getElementById('zoomLevel').innerHTML = zoomLevel; } function updateMarkerStatus(str) { document.getElementById('markerStatus').innerHTML = str; } function updateMarkerPosition(myLatlng) { document.getElementById('info').innerHTML = [ myLatlng.lat(), myLatlng.lng() ].join(', '); } function updateMarkerAddress(str) { document.getElementById('address').innerHTML = str; } function moveMarker() { var lat = parseFloat(document.getElementById('markerLat').value); var lng = parseFloat(document.getElementById('markerLng').value); var newLatLng = new google.maps.LatLng(lat, lng); marker.setPosition(newLatLng) } google.maps.event.addDomListener(window, 'load', initialize); </script> </head> <body> <div id="map_canvas" style="width: 29%; height: 50%; float: left; position: relative; background-color: rgb(229, 227, 223); overflow: hidden;"></div> <b>Zoom level: </b><div id="zoomLevel"> Scroll mousewheel</div> </div> <input type='text' id='markerLat' value='Target Latitude' /> <input type='text' id='markerLng' value='Target Longitude' /> <input type="button" onclick="moveMarker()" value="Move Marker"> </body> </html>

  • Problem with the output of Jquery function .offset in IE

    - by vandalk
    Hello! I'm new to jquery and javascript, and to web site developing overall, and I'm having a problem with the .offset function. I have the following code working fine on chrome and FF but not working on IE: $(document).keydown(function(k){ var keycode=k.which; var posk=$('html').offset(); var centeryk=screen.availHeight*0.4; var centerxk=screen.availWidth*0.4; $("span").text(k.which+","+posk.top+","+posk.left); if (keycode==37){ k.preventDefault(); $("html,body").stop().animate({scrollLeft:-1*posk.left-centerxk}) }; if (keycode==38){ k.preventDefault(); $("html,body").stop().animate({scrollTop:-1*posk.top-centeryk}) }; if (keycode==39){ k.preventDefault(); $("html,body").stop().animate({scrollLeft:-1*posk.left+centerxk}) }; if (keycode==40){ k.preventDefault(); $("html,body").stop().animate({scrollTop:-1*posk.top+centeryk}) }; }); hat I want it to do is to scroll the window a set percentage using the arrow keys, so my thought was to find the current coordinates of the top left corner of the document and add a percentage relative to the user screen to it and animate the scroll so that the content don't jump and the user looses focus from where he was. The $("span").text are just so I know what's happening and will be turned into comments when the code is complete. So here is what happens, on Chrome and Firefox the output of the $("span").text for the position variables is correct, starting at 0,0 and always showing how much of the content was scrolled in coordinates, but on IE it starts on -2,-2 and never gets out of it, even if I manually scroll the window until the end of it and try using the right arrow key it will still return the initial value of -2,-2 and scroll back to the beggining. I tried substituting the offset for document.body.scrollLetf and scrollTop but the result is the same, only this time the coordinates are 0,0. Am I doing something wrong? Or is this some IE bug? Is there a way around it or some other function I can use and achieve the same results? On another note, I did other two navigating options for the user in this section of the site, one is to click and drag anywhere on the screen to move it: $("html").mousedown(function(e) { var initx=e.pageX var inity=e.pageY $(document).mousemove(function(n) { var x_inc= initx-n.pageX; var y_inc= inity-n.pageY; window.scrollBy(x_inc*0.7,y_inc*0.7); initx=n.pageX; inity=n.pageY //$("span").text(initx+ "," +inity+ "," +x_inc+ "," +y_inc+ "," +e.pageX+ "," +e.pageY+ "," +n.pageX+ "," +n.pageY); // cancel out any text selections document.body.focus(); // prevent text selection in IE document.onselectstart = function () { return false; }; // prevent IE from trying to drag an image document.ondragstart = function() { return false; }; // prevent text selection (except IE) return false; }); }); $("html").mouseup(function() { $(document).unbind('mousemove'); }); The only part of this code I didn't write was the preventing text selection lines, these ones I found in a tutorial about clicking and draging objects, anyway, this code works fine on Chrome, FireFox and IE, though on Firefox and IE it's more often to happen some moviment glitches while you drag, sometimes it seems the "scrolling" is a litlle jagged, it's only a visual thing and not that much significant but if there's a way to prevent it I would like to know.

  • Flash As3 Loader Problem

    - by Hadar
    Hi iam trying to load a few external jpegs in As3. It works fine locally in Flash, but it dosen't work at all ion my server. My app also loads a youtube video simultaneously. function drawResult(index,videoID,song_title,thumbnail:String=null) { var theClip:resultRowClip=new resultRowClip (); _clip.addChild(theClip); myArray[index] = new Array(videoID,theClip); theClip.y=0+(43*(index-1)); theClip.rowText.text = song_title; theClip.rowBack.visible = false; if (thumbnail != ""){ theClip.tHolder.visible=true; loadImage(thumbnail,index); } } function loadImage(url:String,index):void { //this.myClip.myText.text += "load image"; // Set properties on my Loader object var imageLoader:Loader = new Loader(); imageLoader.load(new URLRequest(url)); imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, function (evt:Event){imageLoaded(evt,index)}); } function imageLoaded(evt,id):void { //this.myClip.myText.text += "id : evt : " + evt.status; // Load Image var image:Bitmap = new Bitmap(evt.target.content.bitmapData); myArray[id][1].tHolder.addChild(image); myArray[id][1].tHolder.width=myArray[id][1].tHolder.width*0.35; myArray[id][1].tHolder.height=myArray[id][1].tHolder.height*0.35; } Does anyone knows what the problem is ? ** I added two Evenet listeners from io Error : imageLoader.addEventListener(IOErrorEvent.IO_ERROR,ioErrorHandler); imageLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,ioErrorHandler); This is the function for handling the errors : private function ioErrorHandler(event:IOErrorEvent):void { this.myClip.myText.text +=("ioErrorHandler: " + event); } anyway, I got no errors... I also tried to move the listeners before imageLoader.load but it's still the same...no errors and no data loaded.. I change my code to patrikS suggestion : function loadImage(url:String,index):void { //this.myClip.myText.text += "load image"; // Set properties on my Loader object //if (index != 1) return; var imageLoader:Loader = new Loader(); imageLoader.name = index.toString(); //myArray[index][1].addChild(imageLoader); //imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, function (evt:Event){imageLoaded(evt,index)}); imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,completeHandler); imageLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR,ioErrorHandler); imageLoader.load(new URLRequest(url)); } My current completeHandler function(tnx patrikS ) : private function completeHandler(evt:Event):void{ //this.myClip.myText.text += "id : evt : " + evt.status; // Load Image trace("evt target loader name : "+ evt.target.loader.name ); evt.target.removeEventListener(Event.COMPLETE, completeHandler ); var image:Bitmap = new Bitmap(evt.target.content.bitmapData); myArray[evt.target.loader.name][1].tHolder.addChild(image); myArray[evt.target.loader.name][1].tHolder.width=myArray[evt.target.loader.name][1].tHolder.width*0.35; myArray[evt.target.loader.name][1].tHolder.height=myArray[evt.target.loader.name][1].tHolder.height*0.35; //trace (hadar.y + "Y / X" + hadar.x); } It still work only on flash IDE and dosent work on any browser...

  • JQuery Checkbox with Textbox Validation

    - by Volrath
    I am using Jorn's validation plugin. I have a a group of checkboxes beside a group of textboxes. The textboxes are disabled by default and will enable when the matching checkbox is checked. At least 1 checkbox has to be checked which is not a problem. However, when I check more than 2 checkboxes only 1 textbox validates. The form still submits even when the second checkbox is empty. $count = 0; while($row = mysql_fetch_array($rs)) { ?> <tr> <td> <label> <input type="checkbox" name="tDays[]" id="tDays<?php echo $count; ?>" value="<?php echo $row['promoDayID'];?>" onClick="enableTxt();" <?php if((isset($arrTDays) && in_array_THours($row['promoDayID'], $arrTDays)) || (!empty($arrSelectedTHours) && in_array_THours($row['promoDayID'], $arrSelectedTHours))) { echo "checked='checked'"; }?> validate="required:true" /> <?php echo $row['promoDay'];?>: </label> </td> <td align="right"> <input type="textbox" size="45" style="font-size:12px" name="tHours[]" id="tHours<?php echo $count; ?>" <?php if(isset($arrTDays) && in_array_THours($row['promoDayID'], $arrTDays)) { echo "value='" .getHours($row['promoDayID'], $arrTDays) ."'"; } elseif (!empty($arrSelectedTHours) && in_array_THours($row['promoDayID'], $arrSelectedTHours)) { echo "value='" .getHours($row['promoDayID'], $arrSelectedTHours). "'"; } else { echo "value='' disabled='disabled'"; }?> class="required" /> <label for="tHours[]" class="error" id="tHourserror<?php echo $count; ?>">Please enter the Trading Hour.</label> </td> </tr> <?php $count++; }//while ?> This is done using javascript: function enableTxt() { for (i = 0; i <= 7; i++) { if (document.getElementById("tDays" + i) != null && document.getElementById("tDays" + i).checked == true) { document.getElementById('tHours' + i).disabled = false; document.getElementById('tHourserror' + i).style.visibility = "visible"; } else if (document.getElementById("tDays" + i) != null) { document.getElementById('tHours' + i).disabled = "disabled"; document.getElementById('tHours' + i).value = ""; document.getElementById('tHourserror' + i).style.visibility = "hidden"; } } } Please kindly advise in detail as to how this problem can be solved. I am fairly weak in JQuery.

  • Problems with :uniq => true/Distinct option in a has_many_through association w/ named scope (Rails)

    - by MikeH
    I had to make some tweaks to my app to add new functionality, and my changes seem to have broken the :uniq option that was previously working perfectly. Here's the set up: #User.rb has_many :products, :through = :seasons, :uniq = true has_many :varieties, :through = :seasons, :uniq = true #product.rb has_many :seasons has_many :users, :through = :seasons, :uniq = true has_many :varieties #season.rb belongs_to :product belongs_to :variety belongs_to :user named_scope :by_product_name, :joins = :product, :order = 'products.name' #variety.rb belongs_to :product has_many :seasons has_many :users, :through = :seasons, :uniq = true First I want to show you the previous version of the view that is now breaking, so that we have a baseline to compare. The view below is pulling up products and varieties that belong to the user. In both versions below, I've assigned the same products/varieties to the user so the logs will looking at the exact same use case. #user/show <% @user.products.each do |product| %> <%= link_to product.name, product %> <% @user.varieties.find_all_by_product_id(product.id).each do |variety| %> <%=h variety.name.capitalize %></p> <% end %> <% end %> This works. It displays only one of each product, and then displays each product's varieties. In the log below, product ID 1 has 3 associated varieties. And product ID 43 has none. Here's the log output for the code above: Product Load (11.3ms) SELECT DISTINCT `products`.* FROM `products` INNER JOIN `seasons` ON `products`.id = `seasons`.product_id WHERE ((`seasons`.user_id = 1)) ORDER BY name, products.name Product Columns (1.8ms) SHOW FIELDS FROM `products` Variety Columns (1.9ms) SHOW FIELDS FROM `varieties` Variety Load (0.7ms) SELECT DISTINCT `varieties`.* FROM `varieties` INNER JOIN `seasons` ON `varieties`.id = `seasons`.variety_id WHERE (`varieties`.`product_id` = 1) AND ((`seasons`.user_id = 1)) ORDER BY name Variety Load (0.5ms) SELECT DISTINCT `varieties`.* FROM `varieties` INNER JOIN `seasons` ON `varieties`.id = `seasons`.variety_id WHERE (`varieties`.`product_id` = 43) AND ((`seasons`.user_id = 1)) ORDER BY name Ok, so everything above is the previous version which was working great. In the new version, I added some columns to the join table called seasons, and made a bunch of custom methods that query those columns. As a result, I made the following changes to the view code that you saw above so that I could access those methods on the seasons model: <% @user.seasons.by_product_name.each do |season| %> <%= link_to season.product.name, season.product %> #Note: I couldn't get this loop to work at all, so I settled for the following: #<% @user.varieties.find_all_by_product_id(product.id).each do |variety| %> <%=h season.variety.name.capitalize %> <%end%> <%end%> Here's the log output for that: SQL (0.9ms) SELECT count(DISTINCT "products".id) AS count_products_id FROM "products" INNER JOIN "seasons" ON "products".id = "seasons".product_id WHERE (("seasons".user_id = 1)) Season Load (1.8ms) SELECT "seasons".* FROM "seasons" INNER JOIN "products" ON "products".id = "seasons".product_id WHERE ("seasons".user_id = 1) AND ("seasons".user_id = 1) ORDER BY products.name Product Load (0.7ms) SELECT * FROM "products" WHERE ("products"."id" = 43) ORDER BY products.name CACHE (0.0ms) SELECT "seasons".* FROM "seasons" INNER JOIN "products" ON "products".id = "seasons".product_id WHERE ("seasons".user_id = 1) AND ("seasons".user_id = 1) ORDER BY products.name Product Load (0.4ms) SELECT * FROM "products" WHERE ("products"."id" = 1) ORDER BY products.name Variety Load (0.4ms) SELECT * FROM "varieties" WHERE ("varieties"."id" = 2) ORDER BY name CACHE (0.0ms) SELECT * FROM "products" WHERE ("products"."id" = 1) ORDER BY products.name Variety Load (0.4ms) SELECT * FROM "varieties" WHERE ("varieties"."id" = 8) ORDER BY name CACHE (0.0ms) SELECT * FROM "products" WHERE ("products"."id" = 1) ORDER BY products.name Variety Load (0.4ms) SELECT * FROM "varieties" WHERE ("varieties"."id" = 7) ORDER BY name CACHE (0.0ms) SELECT * FROM "products" WHERE ("products"."id" = 43) ORDER BY products.name CACHE (0.0ms) SELECT count(DISTINCT "products".id) AS count_products_id FROM "products" INNER JOIN "seasons" ON "products".id = "seasons".product_id WHERE (("seasons".user_id = 1)) CACHE (0.0ms) SELECT "seasons".* FROM "seasons" INNER JOIN "products" ON "products".id = "seasons".product_id WHERE ("seasons".user_id = 1) AND ("seasons".user_id = 1) ORDER BY products.name CACHE (0.0ms) SELECT * FROM "products" WHERE ("products"."id" = 1) ORDER BY products.name CACHE (0.0ms) SELECT * FROM "products" WHERE ("products"."id" = 1) ORDER BY products.name CACHE (0.0ms) SELECT * FROM "varieties" WHERE ("varieties"."id" = 8) ORDER BY name I'm having two problems: (1) The :uniq option is not working for products. Three distinct versions of the same product are displaying on the page. (2) The :uniq option is not working for varieties. I don't have validation set up on this yet, and if the user enters the same variety twice, it does appear on the page. In the previous working version, this was not the case. The result I need is that only one product for any given ID displays, and all varieties associated with that ID display along with such unique product. One thing that sticks out to me is the sql call in the most recent log output. It's adding 'count' to the distinct call. I'm not sure why it's doing that or whether it might be an indication of an issue. I found this unresolved lighthouse ticket that seems like it could potentially be related, but I'm not sure if it's the same issue: https://rails.lighthouseapp.com/projects/8994/tickets/2189-count-breaks-sqlite-has_many-through-association-collection-with-named-scope I've tried a million variations on this and can't get it working. Any help is much appreciated!

  • Wishful Thinking: Why can't HTML fix Script Attacks at the Source?

    - by Rick Strahl
    The Web can be an evil place, especially if you're a Web Developer blissfully unaware of Cross Site Script Attacks (XSS). Even if you are aware of XSS in all of its insidious forms, it's extremely complex to deal with all the issues if you're taking user input and you're actually allowing users to post raw HTML into an application. I'm dealing with this again today in a Web application where legacy data contains raw HTML that has to be displayed and users ask for the ability to use raw HTML as input for listings. The first line of defense of course is: Just say no to HTML input from users. If you don't allow HTML input directly and use HTML Encoding (HttyUtility.HtmlEncode() in .NET or using standard ASP.NET MVC output @Model.Content) you're fairly safe at least from the HTML input provided. Both WebForms and Razor support HtmlEncoded content, although Razor makes it the default. In Razor the default @ expression syntax:@Model.UserContent automatically produces HTML encoded content - you actually have to go out of your way to create raw HTML content (safe by default) using @Html.Raw() or the HtmlString class. In Web Forms (V4) you can use:<%: Model.UserContent %> or if you're using a version prior to 4.0:<%= HttpUtility.HtmlEncode(Model.UserContent) %> This works great as a hedge against embedded <script> tags and HTML markup as any HTML is turned into text that displays as HTML but doesn't render the HTML. But it turns any embedded HTML markup tags into plain text. If you need to display HTML in raw form with the markup tags rendering based on user input this approach is worthless. If you do accept HTML input and need to echo the rendered HTML input back, the task of cleaning up that HTML is a complex task. In the projects I work on, customers are frequently asking for the ability to post raw HTML quite frequently.  Almost every app that I've built where there's document content from users we start out with text only input - possibly using something like MarkDown - but inevitably users want to just post plain old HTML they created in some other rich editing application. See this a lot with realtors especially who often want to reuse their postings easily in multiple places. In my work this is a common problem I need to deal with and I've tried dozens of different methods from sanitizing, simple rejection of input to custom markup schemes none of which have ever felt comfortable to me. They work in a half assed, hacked together sort of way but I always live in fear of missing something vital which is *really easy to do*. My Wishlist Item: A <restricted> tag in HTML Let me dream here for a second on how to address this problem. It seems to me the easiest place where this can be fixed is: In the browser. Browsers are actually executing script code so they have a lot of control over the script code that resides in a page. What if there was a way to specify that you want to turn off script code for a block of HTML? The main issue when dealing with HTML raw input isn't that we as developers are unaware of the implications of user input, but the fact that we sometimes have to display raw HTML input the user provides. So the problem markup is usually isolated in only a very specific part of the document. So, what if we had a way to specify that in any given HTML block, no script code could execute by wrapping it into a tag that disables all script functionality in the browser? This would include <script> tags and any document script attributes like onclick, onfocus etc. and potentially also disallow things like iFrames that can potentially be scripted from the within the iFrame's target. I'd like to see something along these lines:<article> <restricted allowscripts="no" allowiframes="no"> <div>Some content</div> <script>alert('go ahead make my day, punk!");</script> <div onfocus="$.getJson('http://evilsite.com/')">more content</div> </restricted> </article> A tag like this would basically disallow all script code from firing from any HTML that's rendered within it. You'd use this only on code that you actually render from your data only and only if you are dealing with custom data. So something like this:<article> <restricted> @Html.Raw(Model.UserContent) </restricted> </article> For browsers this would actually be easy to intercept. They render the DOM and control loading and execution of scripts that are loaded through it. All the browser would have to do is suspend execution of <script> tags and not hookup any event handlers defined via markup in this block. Given all the crazy XSS attacks that exist and the prevalence of this problem this would go a long way towards preventing at least coded script attacks in the DOM. And it seems like a totally doable solution that wouldn't be very difficult to implement by vendors. There would also need to be some logic in the parser to not allow an </restricted> or <restricted> tag into the content as to short-circuit the rstricted section (per James Hart's comment). I'm sure there are other issues to consider as well that I didn't think of in my off-the-back-of-a-napkin concept here but the idea overall seems worth consideration I think. Without code running in a user supplied HTML block it'd be pretty hard to compromise a local HTML document and pass information like Cookies to a server. Or even send data to a server period. Short of an iFrame that can access the parent frame (which is another restriction that should be available on this <restricted> tag) that could potentially communicate back, there's not a lot a malicious site could do. The HTML could still 'phone home' via image links and href links potentially and basically say this site was accessed, but without the ability to run script code it would be pretty tough to pass along critical information to the server beyond that. Ahhhh… one can dream… Not holding my breath of course. The design by committee that is the W3C can't agree on anything in timeframes measured less than decades, but maybe this is one place where browser vendors can actually step up the pressure. This is something in their best interest to reduce the attack surface for vulnerabilities on their browser platforms significantly. Several people commented on Twitter today that there isn't enough discussion on issues like this that address serious needs in the web browser space. Realistically security has to be a number one concern with Web applications in general - there isn't a Web app out there that is not vulnerable. And yet nothing has been done to address these security issues even though there might be relatively easy solutions to make this happen. It'll take time, and it's probably not going to happen in our lifetime, but maybe this rambling thought sparks some ideas on how this sort of restriction can get into browsers in some way in the future.© Rick Strahl, West Wind Technologies, 2005-2012Posted in ASP.NET  HTML5  HTML  Security   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • Conversion of BizTalk Projects to Use the New WCF-SAP Adaptor

    - by Geordie
    We are in the process of upgrading our BizTalk Environment from BizTalk 2006 R2 to BizTalk 2010. The SAP adaptor in BizTalk 2010 is an all new and more powerful WCF-SAP adaptor. When my colleagues tested out the new adaptor they discovered that the format of the data extracted from SAP was not identical to the old adaptor. This is not a big deal if the structure of the messages from SAP is simple. In this case we were receiving the delivery and invoice iDocs. Both these structures are complex especially the delivery document. Over the past few years I have tweaked the delivery mapping to remove bugs from original mapping. The idea of redoing these maps did not appeal and due to the current work load was not even an option. I opted for a rather crude alternative of pulling in the iDoc in the new typed format and then adding a static map at the start of the orchestration to convert the data to the old schema.  Note WCF-SAP data formats (on the binding tab of the configuration dialog box is the ‘RecieiveIdocFormat’ field): Typed:  Returns a XML document with the hierarchy represented in XML and all fields being represented by XML tags. RFC: Returns an XML document with the hierarchy represented in XML but the iDoc lines in flat file format. String: This returns the iDoc in a format that is closest to the original flat file format but is still wrapped with some top level XML tags. The files also contained some strange characters at the end of each line. I started with the invoice document and it was quite straight forward to add the mapping but this is where my problems started. The orchestrations for these documents are dynamic and so require the identity of the partner to be able to correctly configure the orchestration. The partner identity is in the EDI_DC40 segment of the iDoc. In the old project the RECPRN node of the segment was promoted. The code to set a variable to the partner ID was now failing. After lot of head scratching I discovered the problem was due to the addition of Namespaces to the fields in the EDI_DC40 segment. To overcome this I needed to use an xPath query with a Namespace Manager. This had to be done in custom code. I now tried to repeat the process with the delivery document. Unfortunately when we tried to get sample typed data from SAP an exception was thrown. The adapter "WCF-SAP" raised an error message. Details "Microsoft.ServiceModel.Channels.Common.XmlReaderGenerationException: The segment or group definition E2EDKA1001 was not found in the IDoc metadata. The UniqueId of the IDoc type is: IDOCTYP/3/DESADV01/ZASNEXT1/640. For Receive operations, the SAP adapter does not support unreleased segments.   Our guess is that when the WCF-SAP adaptor tries to down load the data it retrieves a data schema from SAP. For some reason the schema does not match the data. This may be due to the version of SAP we are running or due to a customization. Either way resolving this problem did not look easy. When doing some research on this problem I found an article showing me how to get the data from SAP using the WCF-SAP adaptor without any XML tags. http://blogs.msdn.com/b/adapters/archive/2007/10/05/receiving-idocs-getting-the-raw-idoc-data.aspx Reproduction of Mustansir blog: Since the WCF based SAP Adapter is ... well, WCF based, all data flowing in and out of the adapter is encapsulated within a SOAP message. Which means there are those pesky xml tags all over the place. If you want to receive an Idoc from SAP, you can receive it in "Typed" format (in which case each column in each segment of the idoc appears within its own xml tag), or you can receive it in "String" format (in which case there are just 2 xml tags at the top, the raw xml data in string/flat file format, and the 2 closing xml tags). In "String" format, an incoming idoc (for ORDERS05, containing 5 data records) would look like: <ReceiveIdoc ><idocData>EDI_DC40 8000000000001064985620 E2EDK01005 800000000000106498500000100000001 E2EDK14 8000000000001064985000002000000020111000 E2EDK14 8000000000001064985000003000000020081000 E2EDK14 80000000000010649850000040000000200710 E2EDK14 80000000000010649850000050000000200600</idocData></ReceiveIdoc> (I have trimmed part of the control record so that it fits cleanly here on one line). Now, you're only interested in the IDOC data, and don't care much for the XML tags. It isn't that difficult to write your own pipeline component, or even some logic in the orchestration to remove the tags, right? Well, you don't need to write any extra code at all - the WCF Adapter can help you here! During the configuration of your one-way Receive Location using WCF-Custom, navigate to the Messages tab. Under the section "Inbound BizTalk Messge Body", select the "Path" radio button, and: (a) Enter the body path expression as: /*[local-name()='ReceiveIdoc']/*[local-name()='idocData'] (b) Choose "String" for the Node Encoding. What we've done is, used an XPATH to pull out the value of the "idocData" node from the XML. Your Receive Location will now emit text containing only the idoc data. You can at this point, for example, put the Flat File Pipeline component to convert the flat text into a different xml format based on some other schema you already have, and receive your version of the xml formatted message in your orchestration.   This was potentially a much easier solution than adding the static maps to the orchestrations and overcame the issue with ‘Typed’ delivery documents. Not quite so fast… Note: When I followed Mustansir’s blog the characters at the end of each line disappeared. After configuring the adaptor and passing the iDoc data into the original flat file receive pipelines I was receiving exceptions. There was a failure executing the receive pipeline: "PAPINETPipelines.DeliveryFlatFileReceive, CustomerIntegration2.PAPINET.Pipelines, Version=1.0.0.0, Culture=neutral, PublicKeyToken=4ca3635fbf092bbb" Source: "Pipeline " Receive Port: "recSAP_Delivery" URI: "D:\CustomerIntegration2\SAP\Delivery\*.xml" Reason: An error occurred when parsing the incoming document: "Unexpected data found while looking for: 'Z2EDPZ7' The current definition being parsed is E2EDP07GRP. The stream offset where the error occured is 8859. The line number where the error occured is 23. The column where the error occured is 0.". Although the new flat file looked the same as the old one there was a differences. In the original file all lines in the document were exactly 1064 character long. In the new file all lines were truncated to the last alphanumeric character. The final piece of the puzzle was to add a custom pipeline component to pad all the lines to 1064 characters. This component was added to the decode node of the custom delivery and invoice flat file disassembler pipelines. Execute method of the custom pipeline component: public IBaseMessage Execute(IPipelineContext pc, IBaseMessage inmsg) { //Convert Stream to a string Stream s = null; IBaseMessagePart bodyPart = inmsg.BodyPart;   // NOTE inmsg.BodyPart.Data is implemented only as a setter in the http adapter API and a //getter and setter for the file adapter. Use GetOriginalDataStream to get data instead. if (bodyPart != null) s = bodyPart.GetOriginalDataStream();   string newMsg = string.Empty; string strLine; try { StreamReader sr = new StreamReader(s); strLine = sr.ReadLine(); while (strLine != null) { //Execute padding code if (strLine != null) strLine = strLine.PadRight(1064, ' ') + "\r\n"; newMsg += strLine; strLine = sr.ReadLine(); } sr.Close(); } catch (IOException ex) { throw new Exception("Error occured trying to pad the message to 1064 charactors"); }   //Convert back to stream and set to Data property inmsg.BodyPart.Data = new MemoryStream(Encoding.UTF8.GetBytes(newMsg)); ; //reset the position of the stream to zero inmsg.BodyPart.Data.Position = 0; return inmsg; }

  • European Interoperability Framework - a new beginning?

    - by trond-arne.undheim
    The most controversial document in the history of the European Commission's IT policy is out. EIF is here, wrapped in the Communication "Towards interoperability for European public services", and including the new feature European Interoperability Strategy (EIS), arguably a higher strategic take on the same topic. Leaving EIS aside for a moment, the EIF controversy has been around IPR, defining open standards and about the proper terminology around standardization deliverables. Today, as the document finally emerges, what is the verdict? First of all, to be fair to those among you who do not spend your lives in the intricate labyrinths of Commission IT policy documents on interoperability, let's define what we are talking about. According to the Communication: "An interoperability framework is an agreed approach to interoperability for organisations that want to collaborate to provide joint delivery of public services. Within its scope of applicability, it specifies common elements such as vocabulary, concepts, principles, policies, guidelines, recommendations, standards, specifications and practices." The Good - EIF reconfirms that "The Digital Agenda can only take off if interoperability based on standards and open platforms is ensured" and also confirms that "The positive effect of open specifications is also demonstrated by the Internet ecosystem." - EIF takes a productive and pragmatic stance on openness: "In the context of the EIF, openness is the willingness of persons, organisations or other members of a community of interest to share knowledge and stimulate debate within that community, the ultimate goal being to advance knowledge and the use of this knowledge to solve problems" (p.11). "If the openness principle is applied in full: - All stakeholders have the same possibility of contributing to the development of the specification and public review is part of the decision-making process; - The specification is available for everybody to study; - Intellectual property rights related to the specification are licensed on FRAND terms or on a royalty-free basis in a way that allows implementation in both proprietary and open source software" (p. 26). - EIF is a formal Commission document. The former EIF 1.0 was a semi-formal deliverable from the PEGSCO, a working group of Member State representatives. - EIF tackles interoperability head-on and takes a clear stance: "Recommendation 22. When establishing European public services, public administrations should prefer open specifications, taking due account of the coverage of functional needs, maturity and market support." - The Commission will continue to support the National Interoperability Framework Observatory (NIFO), reconfirming the importance of coordinating such approaches across borders. - The Commission will align its internal interoperability strategy with the EIS through the eCommission initiative. - One cannot stress the importance of using open standards enough, whether in the context of open source or non-open source software. The EIF seems to have picked up on this fact: What does the EIF says about the relation between open specifications and open source software? The EIF introduces, as one of the characteristics of an open specification, the requirement that IPRs related to the specification have to be licensed on FRAND terms or on a royalty-free basis in a way that allows implementation in both proprietary and open source software. In this way, companies working under various business models can compete on an equal footing when providing solutions to public administrations while administrations that implement the standard in their own software (software that they own) can share such software with others under an open source licence if they so decide. - EIF is now among the center pieces of the Digital Agenda (even though this demands extensive inter-agency coordination in the Commission): "The EIS and the EIF will be maintained under the ISA Programme and kept in line with the results of other relevant Digital Agenda actions on interoperability and standards such as the ones on the reform of rules on implementation of ICT standards in Europe to allow use of certain ICT fora and consortia standards, on issuing guidelines on essential intellectual property rights and licensing conditions in standard-setting, including for ex-ante disclosure, and on providing guidance on the link between ICT standardisation and public procurement to help public authorities to use standards to promote efficiency and reduce lock-in.(Communication, p.7)" All in all, quite a few good things have happened to the document in the two years it has been on the shelf or was being re-written, depending on your perspective, in any case, awaiting the storms to calm. The Bad - While a certain pragmatism is required, and governments cannot migrate to full openness overnight, EIF gives a bit too much room for governments not to apply the openness principle in full. Plenty of reasons are given, which should maybe have been put as challenges to be overcome: "However, public administrations may decide to use less open specifications, if open specifications do not exist or do not meet functional interoperability needs. In all cases, specifications should be mature and sufficiently supported by the market, except if used in the context of creating innovative solutions". - EIF does not use the internationally established terminology: open standards. Rather, the EIF introduces the notion of "formalised specification". How do "formalised specifications" relate to "standards"? According to the FAQ provided: The word "standard" has a specific meaning in Europe as defined by Directive 98/34/EC. Only technical specifications approved by a recognised standardisation body can be called a standard. Many ICT systems rely on the use of specifications developed by other organisations such as a forum or consortium. The EIF introduces the notion of "formalised specification", which is either a standard pursuant to Directive 98/34/EC or a specification established by ICT fora and consortia. The term "open specification" used in the EIF, on the one hand, avoids terminological confusion with the Directive and, on the other, states the main features that comply with the basic principle of openness laid down in the EIF for European Public Services. Well, this may be somewhat true, but in reality, Europe is 30 year behind in terminology. Unless the European Standardization Reform gets completed in the next few months, most Member States will likely conclude that they will go on referencing and using standards beyond those created by the three European endorsed monopolists of standardization, CEN, CENELEC and ETSI. Who can afford to begin following the strict Brussels rules for what they can call open standards when, in reality, standards stemming from global standardization organizations, so-called fora/consortia, dominate in the IT industry. What exactly is EIF saying? Does it encourage Member States to go on using non-ESO standards as long as they call it something else? I guess I am all for it, although it is a bit cumbersome, no? Why was there so much interest around the EIF? The FAQ attempts to explain: Some Member States have begun to adopt policies to achieve interoperability for their public services. These actions have had a significant impact on the ecosystem built around the provision of such services, e.g. providers of ICT goods and services, standardisation bodies, industry fora and consortia, etc... The Commission identified a clear need for action at European level to ensure that actions by individual Member States would not create new electronic barriers that would hinder the development of interoperable European public services. As a result, all stakeholders involved in the delivery of electronic public services in Europe have expressed their opinions on how to increase interoperability for public services provided by the different public administrations in Europe. Well, it does not take two years to read 50 consultation documents, and the EU Standardization Reform is not yet completed, so, more pragmatically, you finally had to release the document. Ok, let's leave some of that aside because the document is out and some people are happy (and others definitely not). The Verdict Considering the controversy, the delays, the lobbying, and the interests at stake both in the EU, in Member States and among vendors large and small, this document is pretty impressive. As with a good wine that has not yet come to full maturity, let's say that it seems to be coming in in the 85-88/100 range, but only a more fine-grained analysis, enjoyment in good company, and ultimately, implementation, will tell. The European Commission has today adopted a significant interoperability initiative to encourage public administrations across the EU to maximise the social and economic potential of information and communication technologies. Today, we should rally around this achievement. Tomorrow, let's sit down and figure out what it means for the future.
