Who else has done this as well? I once put salt on my cereals because our sugar and salt containers were identical.
 
On an April 1 long, long ago, I pranked my parents by switching the salt and sugar. AND THAT WAS THE END OF APRIL FOOLS FOREVER.

Colour isn't everything you think it is in a computer!
 
The recent video "Computer Color is Broken" has set off a small storm on the Internet. We (Inkscape) have even received a bug report about broken color as a result. Blending isn't the only place where using a linear color space is important, as mentioned in my just updated "Color Space and Interpolation" page.
Color Space and Interpolation. Last updated 23 March 2015. The color space used for combining colors or interpolating between color values greatly effects the resulting colors. Most software today uses the sRGB color space. Blending/interpolating in this color space usually leads to unexpected ...

I've discovered café Caritas, near Euston station. Much better than the places at the station and a great place to do business.

I'm really loving modern.ie at the moment - it solves a lot of testing problems with +Microsoft's  unfortunate habit of having lots of old browsers out there in the wild.

I get this in the latest Firefox. Perhaps Mozilla have deprecated some old certificates?

It's true. Even in linear colour space you can get unexpected results if you are doing a gradient in RGB! A straight line interpolation between opposite colours will go through grey when you probably want to just rotate the chrominance.

Developing regular expressions can be a headache if you don't use them constantly. Fortunately, there's a tool that can help.

Something Android needs to get a grip on is phones for children. Children 11+ and younger are getting phones as they go off to bigger schools or parents upgrade. However, +Android​ and Google apps in general are pretty hopeless.

1. Build maturity into the OS. android needs a global maturity setting that apps and websites can take hints from to change their features and content to suit.

2. No porn mode browsing for minors. Browsers must stop adding this as a "worthy" feature on browsers which children have. I'm not living under an oppressive government, I'm just trying to bring up sons

3. Content and DNS filtering for minors. It's of limited value setting this up on your local network if your children have mobile devices. Bake it into the OS.

4. parent controls. Google accounts and android in general desperately need parental controls.

My advice at the moment is if you're not technically savvy and are not going to check over your children's use of mobile devices occasionally, don't get it for them!

What's wrong with Google Plus?

Too many posts from people trying to get your attention to promote what they're doing. Too few posts from people communicating with each other. Posts are increasingly not commented on and increasingly about new stuff.

That's a it better than the Buttons who delayed the start then came on stage so inebriated that he said "he went that way" - looking in one direction and pointing in another!
Then the leading lady had to sing "Cavatina - he is beautiful" about him, and some of our group began to laugh, which started the whole audience laughing their heads off with loud gaffaws...... She cracked up, and had to dance to the tune in the end!
And this was a professional panto!
