The company that provides our web hosting had an issue last night resulting in all of our sites, including the blog, being down for several hours. I had to manually generate the Daily Feed this morning — cue more errors that need fixing. This will likely be the norm for the next couple of days.

You know that feeling when you've been working on something for ages and Excel crashes before you've saved it? Well, that ...

I went downstairs and made myself a drink before the laptop ended up across the other side of the room. It's a massive sheet with 113K+ rows and Excel just said 'No!' when I tried to do pivot tables and row grouping.

@colinwalker Don’t blame you, that really sucks! I’ve heard enough about pivot tables that I’m quite happy not having to deal with them. Ever.

A few weeks after launching (b)log-In I implemented PHP sessions as part of the revised authentication system and discovered that a custom session.gc_maxlifetime can be overridden by default settings unless you also specify a custom session.save_path.

What I didn't know until yesterday was that setting your own path stops garbage collection from removing dead session files after the maxlifetime — I discovered tens of thousands of session files.

I got bored of clearing them out so created a nightly cron job to delete any session files older than the maxlifetime value (1 day) which will help to keep things under control.
