Spider
The Spider is a tool that is used to automatically discover new
resources (URLs) on a particular Site. It begins with a list of URLs
to visit, called the seeds, which depends on how the Spider is
started. The Spider then visits these URLs, it identifies all the
hyperlinks in the page and adds them to the list of URLs to visit and
the process continues recursively as long as new resources are found.
The Spider can configured and started using the Spider dialogue.
During the processing of an URL, the Spider makes a request to
fetch the resource and then parses the response, identifying
hyperlinks. It currently has the following behavior when processing
types of responses:
HTML
Processes the specific tags, identifying links to new resources:
- Base - Proper handling
- A, Link, Area, Base - 'href' attribute
- Applet, Audio, Embed, Frame, IFrame, Input, Script, Img, Video - 'src' attribute
- Blockquote - 'cite' attribute
- Meta - 'http-equiv' for 'location', 'refresh' and 'Content-Security-Policy', 'name' for 'msapplication-config'
- Applet - 'codebase', 'archive' attributes
- Img - 'longdesc', 'lowsrc', 'dynsrc', 'srcset' attributes
- Isindex - 'action' attribute
- Object - 'codebase', 'data' attributes
- Param - 'value' attribute
- Svg - 'href' and 'xlink:href' attributes of 'image' and 'script' elements
- Table - 'background' attribute
- Video - 'poster' attribute
- Form - proper handling of Forms with both GET and POST
method. The fields values are generated validly, including HTML
5.0 input types 'form', 'formaction', 'formmethod' attributes of buttons
are also respected.
- Comments - Valid tags found in comments are also analyzed, if
specified in the Options
Spider screen
- Import - 'implementation' attribute
- Inline string - 'p', 'title', 'li', 'h1', 'h2', 'h3', 'h4', 'h5', 'h6', and 'blockquote' tags
Robots.txt file
If set in the
Options Spider
screen, it also analyzes the 'Robots.txt' file and tries to identify
new resources using the specified rules. It has to be mentioned that
the Spider does not follow the rules specified in the 'Robots.txt'
file.
sitemap.xml file
If set in the Options Spider screen,
the Spider also analyzes the 'sitemap.xml' file and tries to identify
new resources.
SVN metadata files
If set in the Options Spider screen,
the Spider should also parse SVN metadata files and tries to
identify new resources.
Git metadata files
If set in the Options Spider screen,
the Spider should also parse Git metadata files and tries to
identify new resources.
.DS_Store files
If set in the Options Spider screen,
the Spider should also parse .DS_Store files and tries to
identify new resources.
OData Atom Format
OData content using the Atom format is currently supported. All included links
(relative or absolute) are processed.
SVG Files
SVG image files are parsed to identify HREF attributes and extract/resolve any contained links.
Non-HTML Text Response
Text responses are parsed scanning for the URL pattern
Non-Text Response
Currently, the Spider does not process this type of resources.
Other Aspects
- When checking if an URL was already visited, the behaviour regarding how
parameters are handled can be configured on the Spider Options screen.
- When checking if an URL was already visited, there are a few common parameters
which are ignored: jsessionid, phpsessid, aspsessionid, utm_*
- The Spider's behaviour regarding cookies depends on how the Spider is started and which options are enabled. For more
details refer to the Spider Options screen.
The spider is configured using the Spider Options screen.

Happy Valley teen admits hate crime hoax
The sheriff’s office in Clackamas County, Or. said how sorry the kid is about what he did. But what about the family that was taunted? Can you believe what the sheriff’s office said about it all?
"It has been determined there is no actual threat or hatred that exists — It is, and remains a Happy Valley," deputies said.
Happy Valley - where the kids taunt their neighbors with racist threats.
That sure is one friendly place - Happy Valley!

In the long-overdue 7 months since I last posted here, I've gone through one of the most difficult situations of my life – one which I'm not seeking your sympathy for, and also not embarrassed to admit the depression the loss brought on. I'll leave all that stuff to Tumblr for you to read should you wish
[su_quote cite="Kristine Lily"]It's not how hard you fall, but how fast you get back on your feet.[/su_quote]
It's taken me four months to reach a point of personal acceptance at mom's loss, but I'm already jumping up. A quotation that went viral on social media after the loss of legendary southern poet Maya Angelou this week cemented my will to get back up, and do so with no inhibitions.

My work on borrow.ly – a first-of-its-kind geofenced neighborhood household item-sharing platform – has already received positive feedback regarding its business model, both from Ava Seave of Quantum Media and Columbia Business School, and from NYC tech-startup collectives such as StartupBoost, which recently listed borrow.ly as "one of the hottest startups in Silicon Alley." Check out the gallery below to get a sneak-peek at what's to come:

Oh, and did I mention I start a Data Science with Python course at GeneralAssemb.ly Tuesday? Looking forward to learning even more as I build borrow.ly out.
