@JerryTurin @tchbstrd @Noahpinion Wikipedia says it was developed by Bytedance in China, originally released only there under a different name, and then taken international by the same firm under the TikTok name?

@tchbstrd @Noahpinion TikTok is a US product/company that was acquired by China. It’s possible they’ve taken it further, however, they did not innovate or create it

I want to say that this is meaningless and it's all relative, and China is now at the technological frontier so they'll invent more new stuff, and if we were Chinese we'd appreciate their cultural output more, etc. etc. ...But, yeah, kind of. Damn.

@zhil_arf @Noahpinion What has China invented in the last 30 years? I can't think of anything.. 🤯 No fundamentally new tech A few good writers No good music No good films Step back and consider the wealth, population and education levels. It's mind-blowing that they've created almost nothing new

@JohnSmillie42 @caelan_saunders Why is it that American Leaders can not look and see how detrimental wind and solar are to our environment and economy. Look at Germany and other nations that have and are be destroyed by this.

I think the answer to this is no but can you replicate to TimescaleDB from a Postgres instance? I’m trying to think of the simplest cheapest way to get data into a reporting instance without an ETL process.

@jgkoomey Looks like it’s on a retaining wall? Probably best not to lean too hard on it..

@jimwebber There are like 30M cars in the UK; in 15 years the majority of them contain, say, a 50kWh battery. 30M * 50kWh makes a big distributed battery!

@jimwebber Smart meters is why our whole portfolio peaks during cheapest energy hours, from our customers smart-charging their EVs in the cheapest time slots. Customers pay significantly (50-75%) less to charge EVs, and shape grid load so it follows cheap intermittent renewables.

I like computers, but refuse to have smart meters in my house (database error = power cut off etc) as my power company insists. Am I being unreasonable?

@tagir_valeev Watching the “here’s how it’s done proper” - indexing into lookup tables after rounding with no bounds checks, loops allocating on every iteration… Vs original that is so utterly clearly correct, has no logic for the reader to mentally execute, no allocations..

In general, all of these are optional for a private method that 'just works'.

@mdavidallen @EastlondonDev @Tailscale @NotionHQ Backstage is kind of that, like.. Wordpress or Django for company portals, tons of off-the-shelf plugins, trivially extensible. Though it’s very development focused, eg things like “directory of services, their API docs and dashboards”

@duncancampbell Like if you boil some water and then measure the energy delivered by the stove into the pot while it’s boiling, that would Make the stove seem super efficient, but it’s just maintaining an equilibrium at that point

@duncancampbell Guessing, know nothing about fusion: Is there maybe a ton of accumulated heat delivered by the laser “ahead” of the output measurement time window?

@EricMCornelius @Noahpinion Then why do the cost optimising papers not say to build more nukes? You said because they don’t consider storage costs. Can you show an example of a paper that does whole-energy-system least-cost-path optimization that does not include “build tons of PV+Wind” in solver output?

@jakewins @Noahpinion Meanwhile an actual carbon free alternative exists - that we've known how to build for 70+ years. And could be deployed at scale. It isn't because the combined PV + Wind (+ Gas, secretly) lobbyists have vested interest to ensure it doesn't happen. Cheap energy bad for biz.

All the people claiming that solar and wind capacities are fake (because of intermittency) need to explain to me how they think the lines from non-renewable sources are all going down while humanity's total electricity usage is going up.

@nuclearzak @xiaowang1984 @Noahpinion Yes, exactly this. RE enables rapid reduction in burning and shipping of fossil fuels. We then need dispatchable power to meet the gap given by max(demand - all wind in grid - all solar in grid - demand flexibility )

@EricMCornelius @Noahpinion Oh “gen capacity”+”first chart”: Yes that is true, but how is that relevant here, discussion was energy not power. The discussion was: people say pv+wind cannot replace dispatchables, yet less energy is generated by them, more from PV+wind, so they clearly *are* replacing
