<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<br>
it's not very useful for most of your users, but I wanted to submit it<br>
to Hacker News. I think that a more technical post would be better<br>
received. (Or perhaps it will get only 2 upvotes and disappear after<br>
an hour.)<br>
<br>
I'd like to see a mix of <a href="https://www.youpatch.com/about/" target="_blank">https://www.youpatch.com/about/</a> and<br>

<br>
How many computers are you using? Real? Virtual?<br>
<br>
Are you using the Racket web server, Apache or other? Photos?<br>
<br>
Why are you using Racket, and why it's "better" than C? Do you hate<br>
the ugly syntax? Do you implement something very complex that is too<br>
long to write in C? Are you processing the images in Racket or using a<br>
library?<br>
<br>
(A comparison of a pixelation with a naive algorithms and a better<br>
algorithm would be nice, but it can be a lot of work and perhaps it's<br>
part of the secret sauce.)<br>
<br>
Problem with the speed? Memory use? Garbage collection?<br>
<br>
Mix this with pixelated pictures like in<br>
<a href="https://www.youpatch.com/about/" target="_blank">https://www.youpatch.com/about/</a>, pictures make it easier to read and<br>
make it more interesting. Pixelated kittens are always welcome :).<br>
<br>
Some additional ideas: (Not sure if they are very useful.)<br>
<br>
* Add some examples of before and after images, perhaps<br>
original->pixelated->final.<br>
<br>
* Add a "click here to edit this image" button to each image in the site.<br>
