I use ConjuGato on iOS for practicing Spanish conjugations. There’s a game mode where you’re given an infinitive/tense/person and think of the conjugation and you can filter it down to solely irregular verbs to learn the exceptions

There are about 30 Costcos in the UK. You’re right that they aren’t particularly useful for weekly grocery shopping unless you have a car and a large fridge.

I think there’s more preventing the passage of a law protecting an individuals right to abortion than whether it was a matter of political priority.

To pass such a law would require 60 votes in the senate AIUI. Given that this has been a massive part of the republican platform there’s no way ten senators would flip in the current senate.

It could have been passed in the Obama years but I wonder if the public would have had the appetite for it with the assumption that Roe vs Wade would have remained. Let sleeping dogs lie and all that

What this shows to me is the intentional inability for the senate to pass anything but the least offensive bipartisan bills and force other institutions such as the courts to intervene. However as we’ve seen the courts have their own agenda too

Ruby works out pretty nicely in that case!

  def order_list_by_predicate(l, &blk)
    l.partition{|i| blk.call(i)}.flatten
  end

  part(1..6) do |i|
    i % 2 == 1
  end

And you can always sort the incoming list if that's a requirement.

An amusing little sentence to end on:

> Event will be cancelled if hazardous weather conditions are predicted.

You're touching on one of the things that Tesla does that frustrates me to no end. They have this attitude of software being the solution to everything. Waymo has a reason they've mounted lidar to the roofs of their cars, it isn't because they can't build good enough software or their ML models aren't accurate enough, it's because they've realised that you can't just throw a bunch of cameras on a car, add some computer vision algorithms and market it to consumers as being fully self driving capable.

While the wording by the author is technically incorrect in that Google and Facebook aren’t operating a single supercomputer, the computing resources in possession of each company would almost certainly exceed any entry in the top500.

Do you have any thoughts on the benefits of decreasing the fragmentation of the US grid? Presently it's some 3000 utilities who don't have much of an incentive to work together, but you could imagine a future where regions of the US with excess generation transmit to areas at a deficit to diversify the energy supply of any region. This is roughly what's happening in China with their single public utility and usage of HVDC to source renewables from provinces with surplus generation to those operating at a deficit (i.e. the most populous).

With the staggering drop in the cost of renewables and grid-battery storage I just don't see how nuclear has a bright future in any regard.

They're unbelievably capital intensive and have a mean construction time of 7.5 years [0]. I'm from the UK so it's easy to point to Hinkley Point C as an example of this. It's been in planning for a decade and certainly won't be in operation for a similar amount of time, and the currently proposed strike price is around £90/MWh, compared to the ~£60/MWh we've seen from offshore wind projects. Let alone mentioning those have the advantage of being independently deployable with how developers can generate income on a per-turbine basis rather than waiting for the entire farm to be constructed.

And while nuclear is certainly much less CO2 intensive than any fossil-fuel source even a pro-nuclear body's publication shows that wind produces approximately as much CO2/GWh over an installations lifetime as nuclear does [1].

The last time this was posted a few commenters mentioned using PostGIS instead of Uber rolling this themselves.

If anyone's used PostGIS with a similar level of traffic/latency requirements could you comment on your experience?

I can only speak for the brakes. Teslas use regenerative braking on the motor before falling back to traditional frictional brake pads as I understand it. Essentially the motor is put in reverse and that drains off speed. That means less wear on the brakes and so they last much, much longer than an ICE car.

Radiolab had a great episode about nuclear weapons in the US.

At the ~51:26 mark of the episode http://www.wnyc.org/radio/#/747788 there's a great description of what the explosion of a hydrogen bomb was like.

I've always enjoyed the alternate idea of parking areas having shelters covered in solar panels.

Has the nice advantages of keeping your car cool in the summer and removing another piece of complexity in your car.

You could also set up the charge stations such that they either draw from the solar panels or from an alternate power source in the winter when there isn't enough sun to keep a really simple solution.

Do you have any evidence that the passenger was immature or belligerent beyond the United CEO initially claiming so?

And I don't see how you can wave away the incident just by claiming the actions were justified because of aviation law or how United runs.
