  • Image visualization with canvas. How to resize them?

    - by Luca Matteis
    I'm building a website photo gallery for a friend. Images are loaded as simple DOM image objects (<img src="" />), and the size of these images is based on the browser size. So I resize them with CSS. This isn't an optimal solution since CSS resizing seems to change the quality of the image and pixelate it quite a bit. I was thinking of rendering the image with canvas and then resize it with that so that the quality remains effective, but I can't find any info about this online. Any ideas?

  • Aggregating and displaying content from hundreds of RSS feeds

    - by Andrew LeClair
    I'd like to build a website that aggregates and displays content from hundreds of RSS feeds. The feeds will be from different sites: Twitter, Flickr, Tumblr, etc, so the content will be very heterogenous. In a perfect world — and this is more of a side issue — I would like to allow other people to help manage the list of feeds and assign tags to the content from each individual feed so that you can filter the items that are displayed. What I've tried so far: Google Feeds API – I thought this would be the answer, but unless I'm missing something, the FeedController will only output the collected feed content as separate lists. Is there any way to ask the Google Feeds API to aggregate and sort the content from many RSS feeds before displaying? Yahoo! Pipes – This also seemed like a good solution at first. I setup a Pipe that accesses a list of RSS feeds stored in a Google Doc spreadsheet and then aggregates the content. However, the output leaves a lot to be desired; Tumblr video posts, for example, only show a title and a permalink to the post, the embedded Youtube video is lost. PHP – I've seen this question, which looks like a good approach. I'm less proficient in PHP, so although I'm willing to learn, I'd ideally like to find a different approach. Any thoughts? Thanks.

  • Getting req.params in order in Express JS

    - by Adam Terlson
    In Express, is there a way to get the arguments passed from the matching route in the order they are defined in the route? I want to be able to apply all the params from the route to another function. The catch is that those parameters are not known up front, so I cannot refer to each parameter by name explicitly. app.get(':first/:second/:third', function (req) { output.apply(this, req.mysteryOrderedArrayOfParams); // Does this exist? }); function output() { for(var i = 0; i < arguments.length; i++) { console.log(arguments[i]); } } Call on GET: "/foo/bar/baz" Desired Output (in this order): foo bar baz

  • problems piping in node.js

    - by alvaizq
    We have the following example in node.js var http = require('http'); http.createServer(function(request, response) { var proxy = http.createClient(8083, '127.0.0.1') var proxy_request = proxy.request(request.method, request.url, request.headers); proxy_request.on('response', function (proxy_response) { proxy_response.pipe(response); response.writeHead(proxy_response.statusCode, proxy_response.headers); }); setTimeout(function(){ request.pipe(proxy_request); },3000); }).listen(8081, '127.0.0.1'); The example listen to a request in 127.0.0.1:8081 and sends it to a dummy server (always return 200 OK status code) in 127.0.0.1:8083. The problem is in the pipe among the input stream (readable) and output stream (writable) when we have a async module before (in this case the setTimeOut timing). The pipe doesn't work and nothing is sent to dummy server in 8083 port. Maybe, when we have a async call (in this case the setTimeOut) before the pipe call, the inputstream change to a state "not readable", and after the async call the pipe doesn't send anything. This is just an example...we test it with more async modules from node.js community with the same result (ldapjs, etc)... We try to fix it with: - request.readable =true; //before pipe call - request.pipe(proxy_request, {end : false}); with the same result (the pipe doesn't work). Can anybody help us? Many thanks in advanced and best regards,

  • Adobe AIR canvas dimensions messed up

    - by Nikhil
    I'm messing about with Canvas in Adobe Air. But their seems to be some issue with the mouse coordinates. The more I click towards the right, the difference between the draw position and actual click increases. My code is Wb.canvas.fillRect(evt.clientX-canvasTag.clientX, evt.clientY-canvasTag.clientY, 50, 50);

  • Play an AudioBufferSourceNode twice?

    - by alltom
    Should I be able to use the same AudioBufferSourceNode to play a sound multiple times? For some reason, calling noteGrainOn a second time doesn't play audio, even with an intervening noteOff. This code only plays the sound once: var node = audioContext.createBufferSource() node.buffer = audioBuffer node.connect(audioContext.destination) var now = audioContext.currentTime node.noteGrainOn(now, 0, 2) node.noteOff(now + 2) node.noteGrainOn(now + 3, 0, 2) node.noteOff(now + 5)

  • upload a image and insert directly into CKEditor

    - by Timmeh
    I'd like to create the same kind of function tumblr has for uploading images and then inserting them directly into the WYSIWYG editor. I was planning on using uploadify to upload the image, then I am not sure of the method for inserting into the CKEditor. Has anyone done anything similar or know of a plugin that could do this? Ideally I'd like it to insert the image wherever the text cursor was last placed. Thanks in advance, Tim
