One on the disadvantages of having a PhD in computer science is that I get asked really difficult questions. Like - "In gmail on my iPhone I press archive - can I get my mail back?" and "Why have they changed the interface?" Why no easy questions like what's a monad?

I have just discovered that I can send pictures in my tweets and texts. I have no idea if this a good 🍒I suspect it will lead to a lot of ☃️ Probably a silly idea that won’t catch on.

Any idea how to get a carriage return into tweets. Sometimes out of great kindness the iPhone adds a return button to the keyboard - but then it unkindly removes it just when I would like to add a hard carriage return.

Not only can you send pictures of cats in tweets you can also speak the tweets and use voice recognition this is amazing. If fact the voice recognition is better than the typing interface. unfortunately it get some big words wrong.

Discovered that I can speak tweets by pressing the microphone button and it gets it right most of the time this is amazing and saves a lot of time. well done clever programmers

Your majesty will notice that in the first line of her program her loyal subject has put in a module declaration. We do not understand.... I use this technique when rubber duck debugging fails.

I've been playing with dictation SW on my iPhone etc. Recognition is good, but post editing is bad so I need a lot of voice commands to delete the last word and correct typos etc. Any recommendations?

I love home office. The kids have learned that when I'm working in the office with the door closed they can't disturb me. Unless something really important happens, like they see a squirrel out the window, in which case they have to come and get me right away.

Prediction: Brexit has a long delay Uk will take part in EU elections Lab+con get very low vote Remain + leave parties get very high votes This serves as a proxy referendum Might be wrong but solves many problems

Oh and I guess I should add relative energy might be interesting - but Absolute Energy in Joules is the important thing to measure. K times 0 is still 0 even if K is huge. Q: How many Joules does it take to transfer 1 GB of data from your machine to Dropbox? - tricky question.

Once upon a time my boss asked me to study if we should use C++ or Erlang for a specialist XML parser to be used in a product (for reasons of speed not energy). My recommendations was an FPGA We built an FPGA. Relative speed of C++/Erlang was irrelevant compared to FPGA.
