• Smarter System Alerts

  - by mellowsoon

  We have a pretty simple system setup, where I get text messages when there is a system problem. It's nothing fancy. I send an email to my phone number within my logging class for alert levels. It works well enough, but it has one major flaw: A small hiccup in the system/site can turn into dozens of rapid fire text messages. Sometimes non-stop text messages until I log into the system and fix the problem. So I'm looking for pointers on software or services I can use that deal with alerts in a smarter way. Perhaps something that only sends me alerts X number of times within Y number of minutes. I'm not looking for a full monitoring suite. We already deal with that in house. I'm only looking to tackle this single problem.

• MySQL: Column Contains Word From List of Words

  - by mellowsoon

  I have a list of words. Lets say they are 'Apple', 'Orange', and 'Pear'.

I know I could query the table once for each word in my list, and use LIKE and the % wildcard character, but I'm wondering if there is a single query method for such a thing?

  - by mellowsoon

  Hi, hopefully this is a simple question. I have a simple custom forum on my site written in PHP. For security reasons I don't allow any HTML in the forum posts. I only allow certain BBCode tags. I would however like to allow embedded YouTube videos. So my question is this: What's the best (most secure) way to validate the YouTube embed code? YouTube is currently using iframes to embed videos, but obviously I can't just allow the iframe tag. I also need to ensure the src of the iframe is a YouTube URL, and ensure there's no other malicious bits of code in the iframe code.
