If you want to develop insights into how technology and specific services work, doing it yourself really gives you a closer look.<\/p>\n<p>Some time ago, I operated a social bookmarking service using <a href=\"http:\/\/sourceforge.net\/projects\/scuttle\/\">open source software called Scuttle<\/a>. I modified the php code of Scuttle to provide some additional services &#8211; allowing users to promote sites they found useful, listing sites by total value to users. Hacking open code is certainly part of the way I learn.<\/p>\n<p>I began to have difficulties with Scuttle and I never figured out if it was because of the code I added or limitations in the original code. There is a problem with MySQL called <a href=\"https:\/\/en.wikipedia.org\/wiki\/SQL_injection\">sql injection<\/a>. Code included with invited input can cause problems that coder does not intend. This seems to be what happened and while I investigated how to clean up the problem I failed to prevent it completely. It seemed my site was on a list of vulnerable sites somewhere and problems became more frequent. I eventually removed Scuttle from the server.<\/p>\n<p>I am trying it again. This time I am using open source bookmarking software named <a href=\"http:\/\/sebsauvage.net\/wiki\/doku.php?id=php:shaarli\">Shaarli<\/a> (share links). The software does not use a database backend so this will eliminate the problem I encountered with Scuttle.<\/p>\n<p><a href=\"http:\/\/learningaloud.com\/blog\/wp-content\/uploads\/2014\/10\/shaarli.png\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"4175\" data-permalink=\"https:\/\/learningaloud.com\/blog\/2014\/10\/26\/hosting-social-bookmarks\/shaarli\/\" data-orig-file=\"https:\/\/learningaloud.com\/blog\/wp-content\/uploads\/2014\/10\/shaarli.png\" data-orig-size=\"432,249\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"shaarli\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/learningaloud.com\/blog\/wp-content\/uploads\/2014\/10\/shaarli.png\" class=\"aligncenter size-full wp-image-4175\" src=\"http:\/\/learningaloud.com\/blog\/wp-content\/uploads\/2014\/10\/shaarli.png\" alt=\"shaarli\" width=\"432\" height=\"249\" srcset=\"https:\/\/learningaloud.com\/blog\/wp-content\/uploads\/2014\/10\/shaarli.png 432w, https:\/\/learningaloud.com\/blog\/wp-content\/uploads\/2014\/10\/shaarli-300x172.png 300w\" sizes=\"auto, (max-width: 432px) 100vw, 432px\" \/><\/a><\/p>\n<p>My intent is to develop an online source of educational resources.
