ENIanDEM | 4 years ago | on: A backlash against gender ideology is starting in universities

It's literally in response to the posit that trans women would rape strangers in changing rooms. I've tried to make it as far from a strawman as possible by arguing against even a single occurrence of that happening.

Cis women can perpetuate rape. Should we ban them from changing rooms too? How far through the looking glass does this have to go?!

Sorry, I don't buy this concept that hordes of (or any, for that matter) predatory trans women are queuing up for the chance to prowl round changing rooms. Do you, really?

Say you're right. What stops them sneaking in right now? It's not like there are mandatory ID checks at the entrance.

ENIanDEM | 4 years ago | on: Plotly.py 5.0

Hey, thanks for the response - it was actually exactly what you seem to have addressed re the wide & long formats. I'm still using v4.1 and ended up writing my own reshapeForPlotly() function which just called the pandas melt function. Will update to v5 now which sounds like it will simplify things.

I think Plotly is great, btw! I use it a lot with streamlit for quick visualisations of big datasets. Thanks for your work on it. I always found the relationship between plotlyexpress & graph_objects confusing but the docs seem much more explanatory now than I remember from a year or so ago and the code snippets on the main plotly site seem much more abundant. Hopefully as it gets more widely used, the community support on stackoverflow etc will build too.

It's really nice for exploring data. I find whenever I have ~5+ series on a single axis on mpl I start to struggle to differentiate colours & lines etc. I sort of addressed that by getting creative with dash styles etc, but still it's not ideal. Plotly is much more dynamic & I love the call outs etc. I do find it much less intuitive and less well documented than mpl and it's fussy about the shape of the data you give it. Maybe this new version improves on those things.

ENIanDEM | 4 years ago | on: Scientists develop ‘cheap and easy’ method to extract lithium from seawater

Some pretty wild unsourced claims masquerading as facts.

As with pretty much any energy source, (including wind, solar, gas..) nuclear tends to get cheaper the more you build. You can look up FOAK vs NOAK and note the curves. Not sure what you're referring to re difficulty of increasing %share?

How are you measuring "fuel rod lifecycle"? And how does that possibly comparable to "$/kWh solar"?

Here's [0] a good source for some facts. You should note that accounting for the whole lifecycle of mining/processing/operating/defueling/decommissioning, nuclear is ~1/4 of the emissions of solar. And this is only considering electricity; we still have 2-3x the kwh to source for our heating requirements. You're suggesting we get that all sorted with solar & wind too?

Likely just a case of feathering (ha!) the blades: changing their angle of attack so they don't produce as much lift, plus a bit of braking.

Presumably with a bit of surveying pre-construction you can make a good guess at your expected curtailment time and bake that into the financial model

ENIanDEM | 5 years ago | on: Amazon disallows pointing out paid reviews

FWIW, I have a nylon strap-mounted rack (name withheld to avoid accusations of ninja advertising!) which hooks onto the trunk seam. 6 hooks and it's brilliant. Much cheaper than a hitch mounted version, much more compact so I've been able to hang it in a little storage closet in the last few apartments I've lived in and goes on a wide variety of cars without any damage. Rock solid with 3 chunky mtbs on it too. I've even had people come up to me in car parks asking me for details!

Not wanting to derail the discussion but if it was that that put you of the review site you mention, it could be worth reconsidering..

> HSR was never about commuting, capacity is too low

It initially doubles capacity and ultimately triples it https://assets.publishing.service.gov.uk/government/uploads/... (figure 4.2, p76)

What would "proper connection to Europe" have looked like to you? HS2 ends in London where eurostar begins. If HS2 terminated in say, Milton Keynes, I'd wholeheartedly agree with you.

> Linking it to a program of speed improvements on connecting commuter rail would have been a cheaper vote winner

Do you have any evidence for this? Any publicly available report showing even outline calculations? HS2 has always had cross party support.

> before covid19 made public transit irrelevant

In one way or another, the threat of covid will eventually pass. We'll still need public transport when it does.

ENIanDEM | 5 years ago | on: London may have gone into a Covid-accelerated decline

Maybe "slow" is a misnomer or misleading. By slow we're talking about local services which stop at every station. When you relocate fast trains onto another line, those local services benefit considerably. Ultimately you get more local services running, which alleviates the sardine-style travel we currently endure.

ENIanDEM | 5 years ago | on: London may have gone into a Covid-accelerated decline

Sorry, no. High speed rail's main benefit is to increase capacity on existing lines by removing fast trains from the mix. Currently big gaps have to be left in front of the fast trains to allow them to run. The reduction in travel time is a secondary benefit.

I was unaware of this until I recently discovered Gareth Dennis on twitter, who is doing a fantastic job of making up for HS2 ltd's appallingly lacking public engagement "strategy".
