<div dir="ltr"><div><div>Daniel, </div>Congratulations on the launch! I had a play with the site and it's seems very slick. Like Gustavo, I'm curious about the technology stack you used. I had a look on builtwith (<a href="http://builtwith.com/youpatch.com">http://builtwith.com/youpatch.com</a>) and saw that you're using nginx and django in conjunction with racket? </div>Tobias </div><div class="gmail_extra"> <div class="gmail_quote">On 4 February 2014 23:38, Gustavo Massaccesi <<a href="mailto:gustavo@oma.org.ar" target="_blank">gustavo@oma.org.ar</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I looked in your site for a technology stack page. I understand that it's not very useful for most of your users, but I wanted to submit it to Hacker News. I think that a more technical post would be better received. (Or perhaps it will get only 2 upvotes and disappear after an hour.) I'd like to see a mix of <a href="https://www.youpatch.com/about/" target="_blank">https://www.youpatch.com/about/</a> and <a href="http://meta.stackoverflow.com/questions/10369/which-tools-and-technologies-are-used-to-build-the-stack-exchange-network" target="_blank">http://meta.stackoverflow.com/questions/10369/which-tools-and-technologies-are-used-to-build-the-stack-exchange-network</a> How many computers are you using? Real? Virtual? Are you using the Racket web server, Apache or other? Photos? Why are you using Racket, and why it's "better" than C? Do you hate the ugly syntax? Do you implement something very complex that is too long to write in C? Are you processing the images in Racket or using a library? (A comparison of a pixelation with a naive algorithms and a better algorithm would be nice, but it can be a lot of work and perhaps it's part of the secret sauce.) Problem with the speed? Memory use? Garbage collection? Mix this with pixelated pictures like in <a href="https://www.youpatch.com/about/" target="_blank">https://www.youpatch.com/about/</a>, pictures make it easier to read and make it more interesting. Pixelated kittens are always welcome :). Some additional ideas: (Not sure if they are very useful.) * Add some examples of before and after images, perhaps original->pixelated->final. * Add a "click here to edit this image" button to each image in the site.
