There is a difference between processing & counting. From electioninnovation.org/research/how...

Text: Mail ballots are processed.
Before counting a mail ballot, election officials check the voter’s identity, usually by looking at information on an outer envelope. For identity verification, election officials match the voter’s signature or other information on the envelope to the information from voter registration records, as required by state law. Envelopes with missing or mismatched information may be set aside to be corrected by the voter (called “ballot curing;” see below) or rejected by election officials following state laws. Most states start processing envelopes before Election Day, but some wait until polls open on Election Day.

After each voter’s identity is verified, the envelope is opened and the ballot is removed to keep it secret. In some places, mail ballots may be placed into tabulators before Election Day to prepare for vote counting.

Someone needs to be sat down, and have it explained to them, carefully and slowly, what a mobile home is

BTW this is our lawn. Kept verdant not by cunning gardening strategies, but by living in a country that has been hoarding the continent’s rainfall

A green garden “lawn”. Not much grass but other vegetation. A patch of rhubarb is in the foreground, and a plum tree in the middle.

Oh, and the hedge needs a trim

Ouch. That’s seriously not nice. Want to swap?

Weather forecast for next 7 days in Ranheim (Norway). Temperature varies between 9 & 16C, rain forecast for 6 of the 7 days

Not really the main point but surely Shapps would be invaluable, as he could be several of them

Noooooooo!!!!!!!!!! #NoTheoremsToday

I’ve seen the films. The aliens are coming for @grrlscientist.bsky.social

Had the writer bothered to find out what Scandis have for breakfast, eg by simply going to the supermarket and looking at what was sold in the breakfast aisle, she wouldn’t have written this rubbish

Text: Complain all you like, but I’m eating salad as part of breakfast whenever I can. There’s a reason those Scandinavians have colour in their cheeks and live long and healthy lives, and I want in on that.

Just met the new kids on the block

The trick is to define understanding as prediction, and then there is no conflict.

Third, Wilkenfeld stipulates that the representation must be “accurate” in order to mollify quasi-factivists, but the precise meaning of “accurate” is left undefined. In particular, it is unclear whether it is meant to imply truth in terms of reference of the relevant objects, or to simply imply empirical adequacy. Based on the concepts of algorithmic information theory, I argue that the vague quasi-factive stipulation of “accuracy” can be replaced with a verifiable measure of prediction accuracy. Just as Solomonoff quantified the goodness of a particular combination of programs in terms of their ability to accurately reproduce a sequence of observations, we can use prediction accuracy in a particular context to quantify the relative accuracy of two potential instances of understanding. This conception will be further unpacked in the example below.

This is the main square in Trondheim. A large proportion here are catching Pokemon, but that will change. A lot of people in Norwegian shirts. Not seen anyone with and England shirt

From www.theguardian.com/politics/202...

Screenshot of text: “On Wednesday, the chancellor, Rachel Reeves, approved Farage’s formal resignation as an MP by appointing him steward of the Manor of Northstead, the arcane procedure by which MPs are allowed to quit their seats.

In a social media post announcing his departure, Reeves said: “If he wants to spend the summer arguing with a bin, I won’t stop him.””

Hey @grrlscientist.bsky.social, baby gulls!

A pair of baby gulls sat on a flat roof. The photo is slightly over-exposed, due to some poor digiscoping

Someone is enjoying the rain, at least @grrlscientist.bsky.social

A young gull in its grey plumage walking on a flat grey roof. It is raining in a very grey way

For those of you sweltering in most of Europe, you’re welcome to join us here in Trondheim

I think Trump’s problems with eukaryotes goes way beyond algae Source: www.theguardian.com/us-news/2026...

“Like many people who have struggled to control algae blooms in pools or ponds of standing water, Trump’s battle with eukaryotic organisms has shown no sign of being promptly resolved.”

@vdveenb.bsky.social look what arrived!

A tube, presumably with a poster inside, outside a closed office door

@whysharksmatter.bsky.social bad news should you ever visit Trondheim - the hospital doesn’t like sharks

Sign in Norwegian in St Olaf’s Hospital with symbols for wash your hands, clean your teeth, move around and no sharks (with text ‘HAI-gritty sykehus’).

@grrlscientist.bsky.social look who’s back!

A gull (but definitely not a seagull) stood on a railing, looking at the camera with its head turned. A neighbour’s house (presumably with cleaner windows) is in the background

Bob O’Hara@bobohara· May 5

Yep, summer’s here

A deck with several plants in pots and a hanging basket, with a mostly clear blue sky in the background. Oh, and there is a layer of snow over everything

From this month’s Ansible. news.ansible.uk/a466.html

MARY SHELLEY became another victim of the AI backlash when a report by you-know-what announced that the opening of chapter 5 of _Frankenstein_ is '100% AI GPT'-generated. (Facebook, 4 April) [ChB] It has also been revealed that _Hamlet_ consists largely of quotations.

Wait, oh OK. That’s an n

Cans of Panda express “Asparges snitter” (asparagus pieces) written in a font where the n can be misread

Bob O’Hara@bobohara· Mar 28

OTOH this is quite good

Text from a legal decision: “The proffering of an AI-generated AI policy as a remedial measure in a case involving the submission of AI-generated fabrications to this court is, at best, ironic. It suggests that respondent’s engagement with the consequences of his misconduct has been superficial.”

40% off. A deal not to be spat at

Advert for 40% off capsules from the pharmacy. Capsules are (for some reason) called Saliva. They are for a dry mouth and come in lemon and blackcurrant flavours, but still

If I understand Fig. 2 correctly, she is predicting that Universal Consciousness will, via differentiated states, lead to the illusion of separateness as everyone thinks “who stole my car from the car park?”
