Lithium is expensive and rare (a bit of redundancy there, I know). This carbon-based battery could be the holy grail for inexpensive and eco-friendly batteries.
While. this article was in the queue waiting to be posted, the power was lost at ATL—Hartsfield-Jackson Atlanta International Airport—busiest airport in the US. There was a fire in an equipment room that took out the primary and all backups. What a poor design. Every highly-available data center I have visited has two fully-independent sources of power and local backup power (ie, a generator). The failures in ATL effected more that the passengers flying through ATL. The 1,500 canceled flights had cascading effects throughout the US and the world. This is gross negligence on the part of ATL. The inadequacy was certainly obvious to anyone who cared to look but no one looked. Unfortunately, ATL is not the only critical infrastructure that is negligently designed or maintained. It would be wonderful if the event in ATL perpetuates upgrades systems but I will not hold my breath.
The article that I planned to discuss shows how fragile smart systems have become. Advanced control systems in our power grid are merely internet-connected software programs that are vulnerable to attacks just as any other software. These systems are so critically important to our daily life that they require significantly more protection. However, the reality is that they are carelessly built. Most unfortunate is that fixing these known vulnerabilities in this critical systems may not happen until after a massive disruption (such as happened in ATL). There is a better path but it appears to be untraveled.
In this article the author argues for dumb (ie, not smart, IoT) appliances. One problem is that smart appliances are complex and prone to failure. For example, “[t]he last time a repairman came to my house, he told me that he’d had to get a full-time weekday job at Home Depot because nowadays, when appliances break, most people just buy new ones.” He also coined Owen’s Test “Until I can operate my Samsung TV, Blu-Ray player, Amazon Fire TV Stick, and Cisco cable box with a single remote control, the Internet of Things is a hoax.”
At the HPCC summit, Roger Dev (a truly wonderful name) gave a short course on ML. His couresstarts at 40:30 and ends a 52:00 in the video below.
