  • EpiBone Grows New Bones Using Stem Cells

    To grow EpiBone, Tandon explained, scientists take a CT scan of the bone they’ll need to engineer. This helps them create a 3D model. Then, from the model, a 3D printer produces a scaffold (this can be made out of protein and collagen from animal bones or synthetic material). After that, they take stem cells from the patient out of their fat, and those cells are put into the scaffold and then incubated. They regenerate, and form around the bone. This process results in a bone that the body will recognize as the patient’s. The crazy part is that it only takes three weeks to grow a bone that’s personalized to the individual patient.

  • WHAT WENT WRONG IN BRITISH AIRWAYS DATACENTER IN MAY 2017?

    A SPOF UPS. There was a similar AZ-wide outage in one of the Amazon DUB datacenters with a similar root cause, if I recall correctly — supposedly redundant dual UPS systems were in fact interdependent, in that case, and power supply switchover wasn’t clean enough to avoid affecting the servers.

    Minutes later power was restored was resumed in what one source described as “uncontrolled fashion.” Instead of gradual restore, all power was restored at once resulting in a power surge.   BA CEO Cruz told BBC Radio this power surge  caused network hardware to fail. Also server hardware was damaged because of the power surge. It seems as if the UPS was the single point of failure for power feed of the IT equipment in Boadicea House . The Times is reporting that the same UPS was powering both Heathrow based datacenters. Which could be a double single point of failure if true (I doubt it is) The broken network  stopped the exchange of messages between different BA systems and application. Without messaging, there is no exchange of information between various applications. BA is using Progress Software’s Sonic [enterprise service bus].
