“Some people become depressed at the scale of the universe, because it makes them feel insignificant. Other people are relieved to feel insignificant, which is even worse. But, in any case, those are mistakes. Feeling insignificant because the universe is large has exactly the same logic as feeling inadequate for not being a cow. Or a herd of cows. The universe is not there to overwhelm us; it is our home, and our resource. The bigger the better.” David Deutsch
> We're already inundated with mediocre programmers, many of whom have CS degrees, which is precisely why the industry looks at job experience more than credentials
How does looking at job experience help to distinguish good from bad developers?
I think your statement "Once you have plasma breakeven you have a self-sustaining heater basically" is false. According to Wikipedia [1] - if I interpret it correctly - the fusion energy gain factor from plasma must be 5 (!) to have a self-sustaining heater:
"Most fusion reactions release at least some of their energy in a form that cannot be captured within the plasma, so a system at Q = 1 will cool without external heating. With typical fuels, self-heating in fusion reactors is not expected to match the external sources until at least Q = 5"
I like this quote from the "Where We Have Failed" paper:
"We are very uncritical of systems created by the large Internet vendors to that
solve application-specific problems, which have been written, until recently, by
development teams with little background in DBMSs. As such, they have tended to
reinvent the wheel. I am especially amused by Google’s adoption and then rejection
of MapReduce and eventual consistency."
Note also that the blueberry test group (WBB) had a higher score in the practice test already (cf. Table 1). In other words: they were probably better before the consumption of the blueberry juice and stayed better afterwards.
Note that the chart in the linked comic begins in the middle of the last ice age. It ends one or two degree celsius above the mean temperature of the previous 500 years (or so). The big hockey stick at the end is a prediction! At the point in the chart at about 16000 BCE it states that the short warming or cooling spikes have probably been smoothed out (after all, those ancient temperatures are only available by proxy).
Export is not the metric you are looking for. Germany exports lots of solar and wind engery during storms or on hot summer days because it cannot use it. The prices for this energy are low, even negative.
"What’s going on here? Why is Postgres wasting its time, continuing to search even though it’s already found the data we’re looking for?"
Because Postgres has not already found what we are looking for. The query is
select *
from users
where name = 'Capitain Nemo'
order by id asc
limit 1;
Only after Postgres has found all users with the name 'Capitain Nemo' it can sort them by their 'id' attribute and limit the result set to the first one in the sorted relation.
