  • Polymorphic association in reverse

    - by Erik
    Let's say that I have two models - one called Post and one other called Video. I then have a third model - Comment - that is polymorphically associated to to each of these models. I can then easily do post.comments and video.comments to find comments assosciated to records of these models. All easy so far. But what if I want to go the other way and I want to find ALL posts and videos that have been commented on and display these in a list sorted on the date that the comment was made? Is this possible? If it helps I'm working on Rails 3 beta.

  • Deleting YouTube videos using Zend/PHP

    - by Mikael
    Hello, I'm using Zend and PHP to upload and delete videos from my home page. The uploading part is working fine but to download is more complicated. $videoEntryToDelete = $yt->getVideoEntry($videoId); $yt->delete($videoEntryToDelete); I use this code to delete a video and the first row do work. The video object is created and I can get all data from it. But when I try to delete it I get this error message: "You must specify an URI to which to post" Do anyone know how to solve this problem? Thanks!

  • FLVPlayback, go fullscreen smooth?

    - by Marcel
    Hello, Im looking into using and customizing FLVPlayback in a project. How to go about this is clear, but I noticed 1 anoying thing. When going fullscreen, first Flash player goes fullscreen and then briefly shows the FLVPlayback component in its original size, before jumping to show the video itself fullscreen. I noticed on Youtube this doesnt happen. How can I escape this 'flicker' and have the video go fullscreen as the videos do on youtube? Thanks a lot for any tips! Marcel

  • What to filter when providing very limited open WiFi to a small conference or meeting?

    - by Tim Farley
    Executive Summary The basic question is: if you have a very limited bandwidth WiFi to provide Internet for a small meeting of only a day or two, how do you set the filters on the router to avoid one or two users monopolizing all the available bandwidth? For folks who don't have the time to read the details below, I am NOT looking for any of these answers: Secure the router and only let a few trusted people use it Tell everyone to turn off unused services & generally police themselves Monitor the traffic with a sniffer and add filters as needed I am aware of all of that. None are appropriate for reasons that will become clear. ALSO NOTE: There is already a question concerning providing adequate WiFi at large (500 attendees) conferences here. This question concerns SMALL meetings of less than 200 people, typically with less than half that using the WiFi. Something that can be handled with a single home or small office router. Background I've used a 3G/4G router device to provide WiFi to small meetings in the past with some success. By small I mean single-room conferences or meetings on the order of a barcamp or Skepticamp or user group meeting. These meetings sometimes have technical attendees there, but not exclusively. Usually less than half to a third of the attendees will actually use the WiFi. Maximum meeting size I'm talking about is 100 to 200 people. I typically use a Cradlepoint MBR-1000 but many other devices exist, especially all-in-one units supplied by 3G and/or 4G vendors like Verizon, Sprint and Clear. These devices take a 3G or 4G internet connection and fan it out to multiple users using WiFi. One key aspect of providing net access this way is the limited bandwidth available over 3G/4G. Even with something like the Cradlepoint which can load-balance multiple radios, you are only going to achieve a few megabits of download speed and maybe a megabit or so of upload speed. That's a best case scenario. Often it is considerably slower. The goal in most of these meeting situations is to allow folks access to services like email, web, social media, chat services and so on. This is so they can live-blog or live-tweet the proceedings, or simply chat online or otherwise stay in touch (with both attendees and non-attendees) while the meeting proceeds. I would like to limit the services provided by the router to just those services that meet those needs. Problems In particular I have noticed a couple of scenarios where particular users end up abusing most of the bandwidth on the router, to the detriment of everyone. These boil into two areas: Intentional use. Folks looking at YouTube videos, downloading podcasts to their iPod, and otherwise using the bandwidth for things that really aren't appropriate in a meeting room where you should be paying attention to the speaker and/or interacting.At one meeting that we were live-streaming (over a separate, dedicated connection) via UStream, I noticed several folks in the room that had the UStream page up so they could interact with the meeting chat - apparently oblivious that they were wasting bandwidth streaming back video of something that was taking place right in front of them. Unintentional use. There are a variety of software utilities that will make extensive use of bandwidth in the background, that folks often have installed on their laptops and smartphones, perhaps without realizing.Examples: Peer to peer downloading programs such as Bittorrent that run in the background Automatic software update services. These are legion, as every major software vendor has their own, so one can easily have Microsoft, Apple, Mozilla, Adobe, Google and others all trying to download updates in the background. Security software that downloads new signatures such as anti-virus, anti-malware, etc. Backup software and other software that "syncs" in the background to cloud services. For some numbers on how much network bandwidth gets sucked up by these non-web, non-email type services, check out this recent Wired article. Apparently web, email and chat all together are less than one quarter of the Internet traffic now. If the numbers in that article are correct, by filtering out all the other stuff I should be able to increase the usefulness of the WiFi four-fold. Now, in some situations I've been able to control access using security on the router to limit it to a very small group of people (typically the organizers of the meeting). But that's not always appropriate. At an upcoming meeting I would like to run the WiFi without security and let anyone use it, because it happens at the meeting location the 4G coverage in my town is particularly excellent. In a recent test I got 10 Megabits down at the meeting site. The "tell people to police themselves" solution mentioned at top is not appropriate because of (a) a largely non-technical audience and (b) the unintentional nature of much of the usage as described above. The "run a sniffer and filter as needed" solution is not useful because these meetings typically only last a couple of days, often only one day, and have a very small volunteer staff. I don't have a person to dedicate to network monitoring, and by the time we got the rules tweaked completely the meeting will be over. What I've Got First thing, I figured I would use OpenDNS's domain filtering rules to filter out whole classes of sites. A number of video and peer-to-peer sites can be wiped out using this. (Yes, I am aware that filtering via DNS technically leaves the services accessible - remember, these are largely non-technical users attending a 2 day meeting. It's enough). I figured I would start with these selections in OpenDNS's UI: I figure I will probably also block DNS (port 53) to anything other than the router itself, so that folks can't bypass my DNS configuration. A savvy user could get around this, because I'm not going to put a lot of elaborate filters on the firewall, but I don't care too much. Because these meetings don't last very long, its probably not going to be worth the trouble. This should cover the bulk of the non-web traffic, i.e. peer-to-peer and video if that Wired article is correct. Please advise if you think there are severe limitations to the OpenDNS approach. What I Need Note that OpenDNS focuses on things that are "objectionable" in some context or another. Video, music, radio and peer-to-peer all get covered. I still need to cover a number of perfectly reasonable things that we just want to block because they aren't needed in a meeting. Most of these are utilities that upload or download legit things in the background. Specifically, I'd like to know port numbers or DNS names to filter in order to effectively disable the following services: Microsoft automatic updates Apple automatic updates Adobe automatic updates Google automatic updates Other major software update services Major virus/malware/security signature updates Major background backup services Other services that run in the background and can eat lots of bandwidth I also would like any other suggestions you might have that would be applicable. Sorry to be so verbose, but I find it helps to be very, very clear on questions of this nature, and I already have half a solution with the OpenDNS thing.

  • remuxing mpv files from h264 AVI files

    - by crankharder
    I have a bunch of, I think, x264 encoded AVIs that I'd like to convert to m4v so that I can play with Quicktime. Here's how I created them First I dump the vob from DVD with this: $ mplayer -dumpstream -dumpfile new.vob dvd://1 Then I compress it: $ mencoder -oac copy -o new.avi -ovc x264 -x264encopts crf=18 new.vob I tried doing this to convertthem to m4v, but it's blowing up... I tried dumping the h264/acc streams: $ mplayer new.avi -dumpvideo -dumpfile new.h264 $ mplayer new.avi -dumpaudio -dumpfile new.acc And remuxing(?) with MP4Box but I'm getting an error: $ MP4Box -add new.h264#video -add new.aac#audio new.m4v Cannot find H264 start code Error importing new.h264#video: BitStream Not Compliant So not sure what to do now...

  • paperclip callbacks or simple processor?

    - by holden
    I wanted to run the callback after_post_process but it doesn't seem to work in Rails 3.0.1 using Paperclip 2.3.8. It gives an error: undefined method `_post_process_callbacks' for #<Class:0x102d55ea0> I want to call the Panda API after the file has been uploaded. I would have created my own processor for this, but as Panda handles the processing, and it can upload the files as well, and queue itself for an undetermined duration I thought a callback would do fine. But the callbacks don't seem to work in Rails3. after_post_process :panda_create def panda_create video = Panda::Video.create(:source_url => mp3.url.gsub(/[?]\d*/,''), :profiles => "f4475446032025d7216226ad8987f8e9", :path_format => "blah/1234") end I tried require and include for paperclip in my model but it didn't seem to matter. Anyideas?

  • Using Ogg Vorbis in Flash/Flex applications

    - by Aravindan
    I am looking to use ogg vorbis, instead of mp3s to stream audio. It seems that Flash player does not natively support ogg. Is there a codec engine that can be embedded with the app itself that can play .ogg instead of .mp3? In general, what would be a better format than mp3 for streaming audio and that is supported by Flash?

  • Lightbox: how to parse the lightbox dynamically loaded html content (AJAX)

    - by Patrick
    hi, I'm using a (modal) lightbox on a page of my website to display my nodes. I'm using some plugins such as an external jquery-plugin for tooltips and the drupal plugin jQuery Media (to load flash video player for some video file-fields). These plugins are loaded when the main page load and they parse the html content of the page. When I dynamically load the lightbox (and I use AJAX to update its content) the html inside the lightbox is not parse... so no tooltips, no videos. how can I solve this ? Should I trigger the plugins again from Lightbox callback function ? Or should I use something else instead of the lightbox ? Thanks

  • SQL Server: Are temp tables or unions better?

    - by Jonathan Allen
    Generally speaking, for combining a lot of data is it better to use a temp table/temp variable as a staging area or should I just stick to "UNION ALL"? Assumptions: No further processing is needed, the results are sent directly to the client. The client waits for the complete recordset, so streaming results isn't necessary.

  • SQL Like question

    - by mike
    Is there a way to reverse the SQL Like operator so it searches a field backwards? For example, I have a value in a field that looks like this "Xbox 360 Video Game". If I write a query like below, it returns the result fine. SELECT id FROM table WHERE title like "%Xbox%Game%" However, when I search like this, it doesn't find any results. SELECT id FROM table WHERE title like "%Video%Xbox%" I need it to match in any direction. How can I get around this?

  • Is MacBook powerful enough to do Ipad development? or do I need a MacBook Pro?

    - by ronaldwidha
    The title probably says it all. Considering an ipad's processor is nothing compared to a macbook, I would think a Macbook should be more than capable to run the simulator. However, not knowing much about iphone/ipad development, I'd like to get some opinions on this. for e.g. how many apps are typically need to be run for ipad dev (editor, debugger, perf monitor, trace log, etc). are these apps resource (memory, cpu) intensive? please do not take into consideration the actual image, 3d, video, sound development. I understand one would need quite a beefy machine to produce these type of creative assets. What I'm looking at is a machine to do code development, physics, putting together the produced assets (images, vector graphics, 3d video, sound, etc).

  • Loading Youtube Iframe API with RequireJS

    - by davidgnin
    I'm trying to use the Youtube Iframe API inside a module definded with Require JS. As this API is loaded async and calls a function once is loaded, I used a requireJS plugin called "async", that worked before with google maps api. However, this time something isn't working. My module starts this way: define(['text!fmwk/widgets/video/video.html','fmwk/utils/browser','async!http://www.youtube.com/iframe_api'], function (videoTpl,root) { ... }); and chrome console fires this error: Uncaught Error: Load timeout for modules: async!http://www.youtube.com/iframe_api_unnormalized3,async!http://www.youtube.com/iframe_api http://requirejs.org/docs/errors.html#timeout If I don't use async plugin the object YT or its functions are undefinded, and the same happens if I download the API code. The API is loaded sometimes if I put an script tag in the head tag of the html file. All this is expected, but I don't understand because async plugin fails. Thank you for your attention and help :)
