Recently I needed to test against an FTPS server. No big deal, I thought to myself, I’ll just set one up real quick. Boy did I end up having a hard time with that. Not because the task was actually hard but because there’s a bit of a general haziness about the whole idea of [...]
After signing up for a (free) account on tunnelbroker.net and creating a (free) tunnel with my ipv4 address as the endpoint I was able to easily configure my AirPort Extreme. View your tunnel, then click on “Example Configurations” and then “Apple Airport.” In TCP/IP prefs for my MacBooks Network/AirPort Preferences I have “Configure IPv6″ set [...]

It turns out that this is actually a tricky problem. It’s super easy to use the OpenSSH command line stuff via PHP when you have key based authentication set up, but it’s not at all easy to use when you want to go the user/pass route. This is for a couple of reasons: First you [...]
I’ve had a need to use the PHP SSH2 PECL recently (working on making a product, at work, more efficient) And thought I would share some of the preliminary code. You can find it here: vpssh.phps The most interesting thing is not vpssh_core or it’s exec (though it’s good code) the really interesting thing is [...]
If you’re ever in a situation where something is only happening intermittently, and only on a live server, and only while it’s under load… Lets say its not generating any error_log or stderr output, and you cant run it manually to reproduce… (we’ve all been in this situation) How do you get any debugging output [...]
When working with user provided images in PHP you run into a problem. Lets say that you want to generate thumbnails of uploaded JPEGs for users. This is a fairly common use case where you would employ PHP and GD (the most prevalent php image extension.) But when you generate the new, smaller, image what [...]
