When is Easter?



Credit: Android Central

Have you noticed
● Easter is on a different weekend each year
● there’s often a full moon just before Easter

● there’s a full moon right now (10:25 GMT 23 March – may not be visible, depending on where in the world you live)

● Easter is this weekend?

When is Easter? – simple answer
Easter Sunday is the first Sunday after the first full moon on, or after, 21 March each year. Other days of Easter are positioned around the date of Easter Sunday – Easter Friday (Good Friday etc.) is two days before – Easter Monday the day after, etc.

Applying this rule to 2016
● today is Wednesday 23 March
● today is a full moon

● so Easter Sunday is the first Sunday after today – Sunday 27 March 2016


Earliest possible Easter Sunday
“In 1818, as a paschal full moon fell on Saturday March 21 (the Spring Equinox), Easter was the following day – Sunday March 22 – the earliest date possible. It will not fall on this date again until 2285, a span of 467 years.” – Wikepedia1

Latest possible Easter Sunday
“In 1943 a full moon fell on Saturday March 20. As this was before the Equinox the next full moon, which fell on Sunday April 18, determined the date of Easter – the following Sunday, April 25. It will not fall on this date again until 2038, a span of 95 years.” – Wikepedia2

SCAMP – Stanford Climbing Aerial Maneuvering Platform (video)

A major use of drones is for surveillance, where their ability to fly & hover, can provide unique video coverage. Downside is high energy consumption, which limits endurance. SCAMP is able to maximise run-time by landing on a wall or other convenient structure, perching, climbing up, down, or across the wall, as necessary, to optimize camera angle or signal (for video feed or control).

Domino’s has delivered pizza by robot



Credit: indiansnews.com/

Drones as delivery robots have been mooted by a number of companies, including Flirtey Zookal & Amazon.

But drones are not a good mix with human beings, as some have found to their cost, including 18-month-old Oscar Webb, when he had an eye sliced in half by a drone.

Much of the danger of drones is due to the relative instability of flight, & propellors spinning at thousands of rpm. A robot with wheels would eliminate those dangers, & that is what Domino's used for its first trial delivery in New Zealand on 08 March 2016.

What killed your smartphone?



Credit: techandroid.net

Check the article below about the threats to your smartphone. Comments are useful reading too.

http://the-gadgeteer.com/2016/03/17/what-is-the-worst-thing-to-happen-to-your-mobile-phone/

Take home message from the article above, is that the major dangers to your phone are being dropped onto a hard surface, or submerged under water.

So, what can you do?

Drop protection – a good case. Most cases are not good when it comes to impact protection. Most only offer protection against abrasion & very short falls onto a hard surface. Unfortunately, the most likely falls are from waist height. Otterbox’s Defender is the only case I have used which can reliably protect against falls from waist height onto a hard surface. They are also available for a wide range of phones. Biggest disadvantage is that they add more to the bulk of a phone than other, less protective cases.

https://www.otterbox.com/

I also hear good things about LifeProof cases, which also claim to be waterproof. LifeProof was acquired by Otterbox in 20131.

https://www.lifeproof.com/

Cases can also protect against drops by preventing the drop altogether – phones constructed of metal & glass are popular, but are relatively slippery. Most cases are grippier than a bare phone.

Water protection is more difficult. LifeProof, mentioned above, are the only waterproof cases I am aware of. Samsung’s S5 & S7 phones are themselves waterproof. As an older model, the S5 is now available quite cheaply, & the S7 is the very latest.
