When we designed PrimaryPad we knew that editing content on mobile devices would be an issue for a lot of people especially Apple device owners. Today we are pleased to announce that any Apple device running iOS5 will be able to edit pad contents. Enjoy!

Pictogram or Pictograph – Which is right?
Pictogram’s are dead. Beaten back by our relentless drive to use the correct suffix or descriptive term.
Viva la Pictograph revolution..
What the Google search evidence shows us: Pictogram is a more popular term and was used a whole 2 years before pictograph became popular so what happened?
It’s clear that both pictograms and pictographs are becomming less popular from a search perspective. Why could that be?
So my prediction is that by 2020 pictograph will become the chosen way of describing using pictures to represent counts.
We probably have the Americans to blame for this although I do use “color” instead of “colour” by default now and I have come to be rather fond of the way our language is being bastardized into a more generic, future oriented, mash-up.
All of this research just because I made a free online pictogram/pictograph.
In fact the British among us can see we really only started using pictogram more than pictograph in the 50s then it got dropped somewhat then picked back up in the 80s..
British English:
Whereas American’s have been consistent..
American English:
Would you agree that pictograph is “correct” term? I would say that a graph is the correct suffix to use. I would say this based on the fact that if you go to an image search and search for graph you will get a bunch of graphs but if you search for gram you will get mostly outputs from measurements (ie gram in weight) & mammograms and the like..
It’s time to come off the fence pictogram’ers, it’s pictograph and you love it.

WordPress Varnish Cache Config / VCL
Note: I am now providing VCLs in separate branches on github as the Varnish VCL syntax has changed.
Thanks to scoof for documenting the Varnish VCL changes.
What is this for non-technical folks?
WordPress sucks at delivering the same content over and over again, actually, I should rephrase that, wordpress rocks 99% of the time but if you serve a page over and over again it will quickly exhaust your servers resource which will mean wordpress will go slow. Varnish Cache speeds up WordPress by serving pages from memory instead of doinmagicg a bunch of hard work.
Why should I use this VCL?
I have done a number of different VCLs that can be used with varnish and wordpress but this is the final revision for now. It is designed for Varnish 2 but should work on 3 with no to very little modifications, I have tweaked this VCL over a few years and I’m finally happy with it.
Features:
- Supports multiple back-ends
- Supports round-robin
- Supports Purging using the Varnish WordPress plugin
- Supports logged in users
- Supports password protected pages
- Supports Mobile devices
- Provides long client side caching
- Forwards the correct client IP to the web daemon.
- Doesn’t cache 404s, 503, 500 etc.
- Doesn’t cache wp-admin, login, preview, signup
- Caches static objects such as images
- Supports Multisite
- Includes debug/log messages.
- Really clean code, proper tabbing etc.
Requirements
Varnish, WordPress, The Varnish WordPress plugin installed and working, mod_rpaf installed in apache or an nginx equivalent.
Why have I made this?
I was going to make a VCL generator but then I remembered most people will use this VCL as a point of reference and I’m lazy, let’s face it, being lazy is the biggest factor in me backing out of making a generator. The varnish configs I have done before have been overly verbose for what they did and rewriting them and cleaning them up means this config is much easier to understand and modify. Adding logging means that you can easily use varnishlog to debug any problems you have.
What isn’t included?
I didn’t include Custom error messages in this VCL. It’s not because I’m lazy, it’s because custom error messages put a lot of cruft into the VCL and if you want custom error messages you should see this article.
Let me at it!
Varnish v3
Varnish v3.03
Which version of Varnish am I running?
varnishd -V
What do I need to change?
Search and replace myFirstServer and mySecondServer with your server names adding new backends where required. Make sure new backends are added to the round-robin cluster and the purge list.
Once you are happy with your VCL save it in as /etc/varnish/default.vcl (remember to make a backup of your original file) and restart Varnish. Any problems try to debug yourself but if you are stuck just give me a shout, I will be happy to help!
