🪑 Armchair activists, assemble! 😜

We need YOU to sign our petition to the Port to stop coal ships during the Blockade.

The Port calls itself “a global leader in sustainability” — let's pressure them to live up to that claim.

No I don't!

I actually want to save time from doing useless admin stuff, so I can spend MORE time reading, understanding and writing research papers!

The same stupidity with the milk thing.
Except it won't even help the meat industry or lobby either. Well, it may help someone in the lobby group itself, because they can go around claiming to their customers that they did a great thing, while in fact they haven't. But it won't help anybody.

I upgrade to MacOS Tahoe, and it is literally broken. There so many issues, it is beyond count. The newest hit is, I wrote a file with excel and want to open it with another application. But Apple refuses.

Despite a lot of potential for cheap solar untapped, I am not 100% convinced is no need/use for seasonal storage. It would mean wasting a lot of electricity in summer. But given how cheap solar is, that may be fine.
I cannot see how digging up coal, oil or gas could possibly be cheaper…

Upgrading the solar and battery in our house is possibLe. Affordable compared to paying for the expensive grid connection. But what do we do with our excess energy in summer then?
I agree we have plenty solar capacity and it is not terrible expensive, but it is a little complicated.

We could add more panels. Easy. We could save electricity, for example using heat pump hot water. But what about an electric car in Winter.

Mark Schira @mschira.bsky.social · 3d

From my own experience: I live in Wollongong, south of Sydney. Sunny, suburban. Ideal. I have 8kW on the roof. Generates about 1.5 times the energy we need. house uses no gas. But over winter we lack about 300kWh. That is too much for a battery, but we have too much electricity in Summer.

If I understand this correctly, this is huge. It increases the theoretical maximum efficiency of solar cells from 29% to 42%.
And it’s apparently close to application.

Yea, since reality is totally against fossil fuels, they just make up lies and bullshit.
Can we please have back conservatives that care about reality?

Mark Schira @mschira.bsky.social · 9d

But these numbers suggest Germany has about 0.87 MWh/ million people, while Australia has 0.56.
Where is all that power and why does it not see, to be a significant contribution to the electricity grid? Or is it, and
just nobody knows about it?

Interesting, this graph suggests Australia has an sig amount of wind power installed, when seen in context to the population. I was under the impression there was barely any because apparently there is massive prejudice against noise and other negative effects of wind power.

Mark Schira @mschira.bsky.social · 9d

Interesting how much unconstructive prejudice a post with the word Oxford generates.
As per solving Oxford’s admission problems, I think interviews are the only option.
Not perfect , many drawbacks, but i see no other solution to avoid immense waste of time and electricity for AI and counter AI.

$2000? Wow, that’s super expensive, unless it also includes a decent battery.
They cost around €500 in Europe.

Nice! And when you can see it you probably do not have AMD! 🥳

There is a point to this madness. The applicant should know what matters for the reference and they know more about themselves than the supporter.
The letter I send at the end is typically still quite different from the draft - a good recommendation letter draws on both supporter and applicant.

Okay, this is tough for me. The em dash has long been one of my writing ticks! (Drives my editors bonkers.)

I'm not a robot. Honest.

I found this article puzzling, too. So there’s an online fad of people thinking em dashes are a GenAI thing? Seriously? Maybe it’s because — much to the humanities’ disgrace — GenAI writes better than many (most?). Or maybe it simply means that if you use em dashes, you’re a better writer than most.

Yes, absolutely the ICE ban is stupid and should go. Instead increase fuel tax, and reduce electricity taxes.
Also tax cars per weight and dimensions. These last two parameters cause cost to the public in space and road damage. (Even though a weight tax isn’t ideal for BEVs ).

I am asking fundamentally open and curious, not judgmental. Please, can someone explain to me what the "study" and the "research" part is?
I am hesitant to read it, is strikes me as clickbait (ish).
@aukehoekstra.bsky.social you suggest it is opinionated. Maybe, but does it provide new insights?

Mark Schira @mschira.bsky.social · Sep 8

Could not agree more, spelling Mark with a c is downright irritating.

Mark Schira @mschira.bsky.social · Sep 4

Sounds exciting. I have a more basic suggestion, I found Python with an online JupyterLab supported with the GenAI of your choice "How do I plot the following using Python...." is super simple and allows rather powerful plots and all control.
