wynch··on Ask HN: Does Scrum work?
work could mean :

- 'having a broad vision of a project & being able to anticipate', well, this seems unrelated to Scrum to me, Scrum might work, or not. The biggest error in Development management being 'estimates', which was partly solved in scrum by replacing hours/days/months with bananas/story points, but there is still some equivalence in people head. And estimates are WRONG. I've never been good at estimates, and I keep telling my employers that's not what they should be paying me for...

- cutting a project in small iterations so that budget can be adapted / stopped at any time, and developers kept in check (because management don't trust them) : this is maybe the most compelling use-case for scrum / Agile methodologies.

- having happy & productive developers: well this depends on what THEY like. Some people need structure to feel good, and Scrum can provide that. Others are more at ease with autonomy / being responsible for their work...

define 'work'
wynch··on A majority of auto executives still think battery electric cars will fail
Look at the broader picture. I'm talking about world consumption (http://www.tsp-data-portal.org/Breakdown-of-Electricity-Gene...)

Fossil fuels (coal, gas - on which CA depends for more than half its electricity production BTW) represent more than 60% of electricity produced worldwide.

As it is not true in France where I'm from.

Still, when you look at the picture at the 'planet' level, taking into account the big 'giants' whose consumption per capita has yet to reach our western standards - say China, India - Coal is STILL the 1st source for electricity worldwide (source : http://www.tsp-data-portal.org/Breakdown-of-Electricity-Gene...)

It's consumption is deacreasing worldwide, sure...Maybe because resources of coal are in decline ? It's still the 1st resource to produce electricity, with 40% of electricity produced. (electricity is only one part of the energy we consume...)

wynch··on A majority of auto executives still think battery electric cars will fail
As long as we don't find a battery technology providing as much energy density as gasoline, electric cars will only be a fad with no real economic advantage.

Regarding climate change and CO2 emissions, electric cars fail too : making the car AND producing the electricity to run it still produces way to much CO2. (most electricity still comes from coal)

If I had to make a bold prediction : in the future, individual cars (running on gas or electricity) will be rare !
