Keynote for the static ones, After Effects for the gifs


I got the same impression, especially the "Powered by WordPress.com VIP" at the bottom


By looking at the headers you now have a great way of writing some analytics tools to see how much your website is shared on Facebook...


I would imagine that they cache the page contents and hence hit a URL only once in a certain period of time, thus skewing any analytics built around this.


Yeah it's cached by Facebook. That's why if you want to change your meta and/or open graph tags info, you need to feed your page to Facebook's Url Linter (https://developers.facebook.com/tools/lint/).


you can also programmatically force it to refresh the cache via a POST to https://graph.facebook.com/?id=http://google.com&scrape=...


If you register your site with Facebook, you can get that information on Facebook's end:

under "Domain Insights."


ive been writing python for ages but never found a simple introduction to how to package modules - always thought it was voodoo, so thanks a lot! so simple...


It is but now you know the correct incantations ~computers~ :)


Launched http://www.TrickedOutTimeline.com on HN in february (see http://news.ycombinator.com/item?id=3522255) and have made ~$2500 on around $100 costs from advertising and hosting on google app engine. Nothing huge, but good for a weekends work with a friend!


I remember your post when you guys launched. I went to your site and spent about 5 minutes trying to figure out what the hell it was. I see now that you've greatly improved this, and added several clear examples that show it. Great work!

Do you mind answering a couple of question? I'm curious how you guys have advertised this product, and where your users come from.


yeah no problem - shoot me an email if you want. we took a lot of feedback on board from that HN post and really changed the layout since the initial launch. Most of our traffic comes from blogs and StumbleUpon! We are also now on the first page of Google for some relevant search terms


really cool tech here! have you guys published any papers on this?


Not yet but actually we're working on it. We hope to publish something before end of 2012! Any idea on the good confs for such subject?


Looking forward to it! Not sure for your subject, as I am computer vision guy. In fact, I work on large scale image recognition and there is something about this which I love...there's a lot of potential for image analysis here.


just a design point - i find the black on dark green background quite uncomfortably hard to read on my screen!


You should have seen the inverse ;)

I'm constantly playing with the design and I've also found it can be a bit bright; I'll be looking to refine it soon.


this is very good! is it possible to save the filtered images locally?


Try this one: https://gist.github.com/1747707

It basically uses the toDataURL() method to get the image data of the canvas.


well, this method downloads a file without a .png at the end (and most users are overwhelmed with the task of renaming a file)

think there is something coming with BlobBuilder and FileSaver, but i haven't hat time yet to give it a spin http://dev.w3.org/2009/dap/file-system/file-writer.html#idl-... and an example here http://updates.html5rocks.com/2011/08/Saving-generated-files...


hah yes you are right, thank you


i do agree, but also eager to get the likes in. may a/b test like to download/suggeting a like after download.


A/B testing is fine and all, but you might want to think of it from an ethical standpoint.

Are you okay with requiring someone to shout "I like this service" to be able to use said service, on first use? Does it feel right to disclose the like requirement after the user has already put time in using the service?

It sounds backwards to me at least and you're definitely alienating some people, but if you think it's no big deal then you're entitled to your own opinion.


Rather than A/B test the conversion rates of liking before-or-after, think really hard about what you want to convey. What does a like give you? Is it worth alienating potential users?

You don't need an A/B test to tell you that "If you enjoyed our service, please Like us on Facebook." is a friendlier, more positive request. People have already tweeted about it more than they liked it on Facebook without additional prodding. Let the site stand on its own merits, rather than trying to force promotion through potentially sleazy methods.
