ssh_forget_host is keygen for Chrome OS in crosh

By -
As I've spent too much time searching for this... I want to quickly capture this for the world (and myself) for future reference.

SSH allows you to connect to a remote machine (e.g. a Raspberry Pi that does not have it's own screen or keyboard connected).
On the first connection, your operating system will store a signature of the remote machine that you presumably trust, and then on subsequent connections, the signature is checked to ensure you are not subject to a man-in-the-middle attack.

If, like me, your Pi is rebuilt or cloned, then you will see a warning, something to the tune of "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!"

On a Mac you can issue the ssh-keygen -R command, but what do you do on a Chromebox (or Chromebook) in the terminal (or crosh) command?

The answer is simple:
ssh_forget_host
Enjoy.

Planning what we feed our brains

By -
Inspired by my very smart niece, Ilana. I’m no expert on how the brain works, but I do find it fascinating to understand snippets of how I can optimise this fantastic super computer tuned for *real* (as opposed to artificial) intelligence, that we all always carry around with us. TED is jam packed with fantastic presentations about this . Yesterday my niece told me about the early evidence and research in progress of how the brain process facts and data from short term memory to medium term memory to long term memory. From my limited understanding, I’ve translated it to a field I know a bit more of: Just like computers (or the cloud ), the brain also have various kinds of memory, some faster but more scarce, other slower and in greater supply. Data pipelines would process some of the streams of incoming data, and keep relevant info, discarding noise. And eventually data scientists and analysts would process the data to find insights, or train new machine learning mod...

I told you: Google I/O sold out quickly

By -
I recently suggested that developers interested in attending Google I/O should act quickly... Yesterday the public ticket sales for Google I/O opened... and less than an hour later, all were sold out! ... and we're thinking about how we can create a fairer distribution of tickets, rather than just see who can fire up Chrome the quickest after registration opens... If you have any smart ideas, please shout! Also remember that you can watch the live stream of the event and follow the IO team on twitter .

Thank you to the BMJ for the wonderful opportunity to present the keynote #qfk4 at the International Forum for Quality and Safety in Healthcare #quality2015. It was a real privilege and honour to share the stage with HRH The Royal Princess and other distinguished presenters and experts. The content below is intended to provide links for further reading to support the presentation I delivered yesterday at Excel, London. Part 1: recent changes in technology that opens up new opportunities With the story of Mihir Garimella  and his cheap quadcopter, I highlighted four huge shifts in technology: Smaller cheaper more connected  and smarter (using data and processing power to become more relevant, proactive and our of the way) This change was mostly driven by the growth of mobile phones . As examples, I discussed Google Iris Google Nanoparticle platform  (and especially this ) Google Flu trends (and how you can do this yourself ) and this Jawbone...
