@meena move fast. forget things.

Tomorrow there will be a pro-nuclear-energy rally in Augsburg, followed by one at the power plant at Gundremmingen.

I made flyers.

Just open-sourced the code, schematic, PCB layout and Bill of Materials for the air quality monitor I'm working on.

let's say that I'd like to have a single board computer for

1) publishing my personal indie blog as a Tor onion service

2) having an IRC bouncer

3) having my own instance of a fediverse service (pleroma ?)

4) having my own xmpp server

what is the best alternative ?

This is one of the articles that introduced the concept of a Carbon Footprint.

It is neither correct nor helpful to claim that this concept was invented by the oil industry and therefore rubbish. CF metrics are very useful at macro level. I know the oil industry used the concept to try and devolve responsibility. But that does not make CF a bad metric.

Hydrogen, which has been touted as a low-emission alternative for aviation, could end up polluting more than coal, a study finds.

Hey, you know that meme that "100 companies are responsible for over 70% of emissions" that's used to imply that individual action is useless against climate change?

It's worth taking a look at the actual report that that meme comes from - the CDP Carbon Majors Report 2017: https://b8f65cb373b1b7b15feb-c70d8ead6ced550b4d987d7c03fcdd1d.ssl.cf3.rackcdn.com/cms/reports/documents/000/002/327/original/Carbon-Majors-Report-2017.pdf

That report did state that, in the 1988-2015 period, 100 fossil fuel companies were responsible for 70.6% of global industrial GHG emissions... but what does "responsible" mean?

Turns out that their methodology looked at two things - "scope 1" (operational emissions - that is, their actual emissions) and "scope 3 category 11" (use of sold products).

In that period, 58,328 Mt of CO2 equivalents were actually emitted by the fossil fuel companies in question.

576,506 Mt of CO2 equivalents were emitted in the "use of sold products".

That is, *not* by the fossil fuel companies.

By their customers.

Fuck off entirely with the "100 companies emit >70% of CO2" meme.

There’s a new LOTR themed cryptocurrency going around now and their birdsite @ is TheTokenOfPower which begs the question: did they understand the books?

The ring of power was pure, corrupting evil that had to be destroyed.

Anyway, GPUs and ASICs are vulnerable to water, fire, and baseball bats.

This is apparently a TI-77 Plus graphing and scientific calculator. So far, I've been unable to find any documentation or even marketing material on it. There's a similar calculator with an LCD that I was able to find, but nothing in this form factor with a CRT

If it went into production, this is probably the one of the thinnest, if not *the* thinnest, CRT in a non-lab setting

beautiful day in the neighborhood

Absolutely gorgeous illustrations of metropolis Tokyo. There's nothing better than the combination of rain + neon colors.

Wellbeing, my new lifestyle magazine for beings who live in wells

I wrote an article about the need for low-carbon and #sustainable #computing and the path towards zero-carbon computing.

tl;dr:

** The problem:
* By 2040 emissions from computing alone will be close to half the emissions level acceptable to keep global warming below 2°C. This growth in computing emissions is unsustainable: it would make it virtually impossible to meet the emissions warming limit.
* The emissions from production of computing devices far exceed the emissions from operating them, so even if devices are more energy efficient producing more of them will make the emissions problem worse. Therefore we must extend the useful life of our computing devices.
** The solution:
As a society we need to start treating computational resources as finite and precious, to be utilised only when necessary, and as effectively as possible. We need frugal computing: achieving the same results for less energy.
** The vision: please read the article, I'm out of characters.

I feel like there's an ideological cold war out there in tech (and possibly in tech education) between

1. "computers MUST be fully user-programmable or a massive social disaster will occur on the order of Fascism and Communism, but now with pervasive surveillance"

vs

2. "computers are far too dangerous to allow users to control, so they MUST be centrally managed and filtered by a genius tech elite".

I stand firmly in camp 1.

Whenever I see people espousing Camp 2 ideas, I shiver and run.
