Update this tutorial
Hi. I would appreciate an update for this tutorial :) with latest version of deps.
scrape1 HN url needs to be updated with https
In the scrape1 tutorial, the HN url needs to be changed from (def *base-url* "http://news.ycombinator.com/") to (def *base-url* "https://news.ycombinator.com/") in order to work correctly.
Templates can be set to autoreload as of 1.1.2
The paragraph starting "Your templates do not automatically reload..." could be removed or updated in light of a new auto-reload feature.
Auto-reloading (1.1.2)
(net.cgrand.reload/auto-reload ns)
Each time a resource or file used by a template/snippet is updated the namespace is reloaded (as per (require ... :reload))
Scraping nytimes.com outdated
It appears that the HTML source of nytimes.com was changed to HTML5 and the div tags for stories became article tags. As a result, the *story-selector* doesn't work anymore. My quick fix is to change :div.story to :article.story.
scrape1 does not match titles and points correctly
As the screenshot shows, the news site at ycombinator does not always render the amount of points for a news item (likely when no points are given yet). This causes the scrape1 algorith to combine a headline with the points amount of the next item in the resulting output lines.
REPL will not start.
Error Output:
Tried to use insecure HTTP repository without TLS.
This is almost certainly a mistake; however in rare cases where it's
intentional please see lein help faq for details.Tried to use insecure HTTP repository without
TLS.

links to source and html are (still) broken
title says it all :)
:data should be :links or vice verse
Either
:links (see dummy-context) in the text should be :data or
:data (see defsnippet section-model) in the text and sources should be :links
Random RuntimeException: Unable to resolve symbol...
Completely new to Clojure. Sometimes the examples work, other times I get exceptions (on the same function calls) and I haven't detected a pattern, nor do I know how to resolve these, e.g.:
CompilerException java.lang.RuntimeException: Unable to resolve symbol: hn-headlines-and-points in this context, compiling:(/private/var/folders/sn/n9z1wyp964x889brp42y29yw0000gq/T/form-init3666505936293348284.clj:1:1)
I'd appreciate any pointers.

It seems like the composite selector, #{[:td.title :a] [:td.subtext html/first-child]}, is incorrectly selecting bits of the page. By itself it seems fine:

nilI'm using Enlive 1.1.1 and Clojure 1.4.0.
ycombinator returns 403
I'm trying to follow along, but (fetch-url *base-url*) throws an IOException when trying to access https://news.ycombinator.com:
IOException Server returned HTTP response code: 403 for URL: https://news.ycombinator.com/ sun.net.www.protocol.http.HttpURLConnection.getInputStream (HttpURLConnection.java:1615)
I tried changing *base-url* to http://news.ycombinator.com, but that didn't work. I can access https://news.ycombinator.com normally in my browser.
