Grep treats the pattern as a newline-separated list of items to search for.

From https://www.gnu.org/software/grep/manual/grep.html#Introduct...: "Since newline is also a separator for the list of patterns, there is no way to match newline characters in a text."

It's a little more clear in the abstract. (At http://spie.org/OPO/conferencedetails/digital-image-processi...)

> x265 outperforms libvpx in most cases, but the performance gap narrows (or even reverses) at the higher resolutions.

So libvpx is sometimes better than x265 at resolutions > 1080p.

If you had more money, you could trade futures, which are mentioned in the article. If you sell the future before the date of delivery, then you never have to deal with the physical aspect of the commodity. There are lots of online brokerages you can use for this, for example, E*Trade and TradeStation. But they have higher minimums than $1000.

With $1000, you could trade ETFs, for example USO [0]. The account minimums for ETFs are lower. If you look at what's inside USO [1], it's basically a wrapper for a future (NYMEX WTI Crude Oil CL).

New comment by uraza in "Swiss to vote on 2,500 franc basic income for every adult"

From the original article:

  In March, Swiss voters backed some of the world's strictest controls
  on executive pay, forcing public companies to give shareholders a
  binding vote on compensation.

  A separate proposal to limit monthly executive pay to no more than 
  what the company's lowest-paid staff earn in a year, the so-called
  1:12 initiative, faces a popular vote on November 24.

The two articles you linked to refer to the first proposal.

set = <> looks like the other empty container literals, but it's not consistent with the literal notation for sets with one or more elements: my_set = {1,2,3}.

I believe sciencerobot is saying that "<>" could be used as the empty set literal.
