Been happily signing, decrypting and , occasionally, encrypting email in Thunderbird using the Enigmail plugin for years. This morning's routine upgrade has broken that - looks like it now has built-in encryption (good) which doesn't seem to just use ~/.gnupg keys as one would expect (extremely boneheaded). Not impressed at all.

@xurizaemon … the 110V kettle will boil at ~half the speed.

So, it's not that the circuit breaker limits the power of the kettle in use, it's that the common use of that size CB will limit the design of the kettle in the first place: the choice of the resistance of its element.

BTW, European voltages are now standardised on 230V +/- a percentage tolerance to include existing continental 220V and UK and Ireland 240V. Single market for kettles, etc.

@petrichor @cypnk

@xurizaemon Yes, that's a rather muddled article. Some electronics (most stuff with switch-mode power supplies) will work off 110 or 230V but kettles need to be designed for specific supply voltages. If you use a 230V kettle on a 110 volt supply it'll have roughly half the voltage and half the current so boil at one quarter of the speed. If you have a 230V kettle designed to draw 10 amps and a 110V kettle also designed to draw 10 A, each on their own voltage, then…

@petrichor @cypnk

@wezm Irrelevant (unless it's part of the source of this editor, as I suspect) but I hope the author of utf8_to_codepoint has been given a clip round the ear for its trusting lack of validation. That's the sort of nonsense which gives C & C++ their (deserved) bad names.

@wizardofosmium Or a VoIP phone with the Lochmaddy area code?

Try something like: to see who the provider is, at least to some extent. E.g., my VoIP number with a Lybster area code is actually through but shows as “Magrathea Telecommunications Limited” who presumably own a block of 1000 or so numbers in the Lybster area code.

@liw The descent stage is not orbiting; rather the opposite, really. @joeyh

@dredmorbius You realise that's a significant part of why the US got into the International Space Station: to give employment to Russian rocket scientists who would likely otherwise go and work for Iran or similar?

So, the ISS is a rather quick pyramid? Sounds about right.


@jens @cypnk Or it's a market segmentation thing: they'll sell the bitcoin-appropriate version for more money?

@kensanata 1 metric Scott Manley and 1 metric Doug Ellison for scale looking at a model of Curiosity. (If it's the one I'm thinking of it was Doug who made that “7 minutes of terror” video or maybe his was the original one for Spirit and Opportunity - bit hazy on the details.)


@kensanata As @ersatzmaus says, Perseverance is about the same size as Curiosity and only a little more massive, 1025kg vs 899kg. The EDL (entry, descent and landing) process for P is the same as it was for C with a few tweaks; P can do a bit of visual navigation during the landing phase to avoid cliffs, etc.

The two other spacecraft to arrive at Mars recently are from the UAE and China. The Chinese one has a lander, not sure what size, but smaller than P & C I assume.

@kensanata Which one? Perseverance is the third in few days.

@jens Don't get me wrong; I'm not suggesting BTC energy consumption is “only” whatever, I think it's a ridiculous waste and ethically completely unjustifiable even if it's actually a lot less than some claim.

My point is a bit tangential [¹]: the confusion between electricity and total energy use misleads people on what proportion of our energy actually comes from renewables. E.g., 40% renewable electricity might really only be, say, 6% of energy.


[¹] I.e., nothing to do with it.

@zens Indeed - I read that the generation failure was roughly 2/3rds fossil, 1/3rd renewables + the grid failures. But you're probably right, it'll be blamed on wind.

@amiloradovsky @cypnk

@zens No, it wasn't. Most of the lost generation was from fossil-burning plant failing in the cold.

@amiloradovsky @cypnk

@tinyrabbit “The BTC network consumes more energy annually than a number of first-world countries (Argentina and the Netherlands are the ones I remember right now).”

More *electricity* than those countries. BBC article you link says BTC: 121 TWh/a. WP [¹] says NL: 119 TWh/a of electricity.

This confusion between electricity and energy is far too common. Typically energy consumption is around 5 to 10 times electricity.

@kemonine You could try talking to Steve Roberts who spent a few years cycling round America on large geeked-out recumbent bicycles with a chorded one-handed keyboard on the handlebar so he could write while travelling.
