Get Lat,Long from Google Maps Bookmarklet

Chris McKee — Fri, 19 Feb 2010 21:14:50 +0000

I was getting slightly bored (and pissed off) with using the “link to” on Google Maps to get the Latitude,Longitude for making a market file. So this will be a storage area that I’ll be adding more and more bookmarklets to, to simplify my life and hopefully to simplify someone elses. Get the longitude and latitude from … Read on Squire

Chris McKee — Sat, 26 Sep 2009 21:35:11 +0000

Magento Beginners Guide… Its a Book for Magento Beginners, No-Really

Chris McKee — Fri, 18 Sep 2009 21:09:05 +0000

Anyone who already knows me knows I have a ridiculous amount of books; mostly e-books thesedays (the future-wifey takes exception to a book-based house-invasion) and mostly for reference. I am by all definition a book whore. So when PACKT offered to send me their latest so I can review it and didn’t stipulate any real … Read on Squire

Ever wondered why Magento Layered Cache Was SOOOO Slow and Greedy

Chris McKee — Mon, 31 Aug 2009 15:13:01 +0000

Ever wondered why Magento Layered Cache Was SOOOO Slow and Greedy, as in it sees mysql as its bitch and likes to consume as much resource as humanly possible. This is a SINGLE update query based on my test 'footwear' store, several attributes etc. Course the more attributes you have the slower it goes.

Chris McKee — Wed, 29 Jul 2009 10:30:50 +0000

I was nocking up a client script to drag down a news-feed and post it to a Wordpress blog; the script ran fine, no posts appeared and no errors occurred… irritating.

So I figured I'd share this pain in the arse issue fix to the "HTTP/1.1 417 Expectation Failed Error"

Error Contains None UTF-8 Content… Bleh When encoding use content to XML there are often issues that occur… 99.9% of the time stemming from users copy-pasting from MSWord in to text boxes and all the odd characters being carried through.

Solution 2 – Running the Layered Navigation Cache in bits from PHP-CLI Part Three Solves a lot (GO BADGER) So not everyone has half a gig of ram to play with, that’s a git. Funnily though, I don’t have PS on the server I’m developing Magento on (why, oh god why?) so I cant build a shareable … Read on Squire

Magento Commerce – Layered Navigation Cache Error

Chris McKee — Mon, 16 Mar 2009 14:01:01 +0000

When running a cache refresh on Layered Navigation the script times out producing either an Error 500 or server based error. The problem is then made worse by magento's failure to recognise that the process didn't complete.
