There will always be some frauds and mentally-ill people, I think that is recognised, hence the lack of arm-flailing.

Nice. I probably won't be around then. Would it be like sonar, as an analogy, measuring the GW Stochastic Background? I just saw this Arxiv paper as I was looking up what you were on about. Have you seen it: Stochastic gravitational wave background: methods and Implications

I thought it was interesting, and seems to be working without further political uproar... as it would be your side of the pond..

I originally put this in the 'Whiteboard'' thread and realized it's in the wrong place. To lift it to here, do people think this was handled well?:

That part about him did cross my mind, but I still thought it was relevant. If you knew about neither, that's how it would look, I think. Here's a story from today of a UK teen abusing in a gender-neutral school toilet. Do you think this is handled well?

Also, one should note that a technique that is at 'proof of concept', doesn't mean it can necessarily be applied substantively in the wild. Not saying this instance is so, but it's something to be aware of.

I reside in the Aquarian/Piscean part of the Zodiac, so I'm more logical than the other zones. It's rubbish.

Isn't it amazing that this theory just keeps on giving and being confirmed?

@Sensei Bear in mind, implementation of security features varies across continents and countries. US aren't using Chip and Pin yet, for instance. The relative risk between nations is not uniform.

Classy and en pointe.

Even black SC judges don't agree on AA. Our discussion is a microcosm of the problem, so let's take note of that and hang back a little when it gets too hot... https://www.reuters.com/legal/us-justices-jackson-thomas-illustrate-heated-us-debate-race-2023-06-29/

If you want to fill the grain with dust, then maybe so. Cabinet makers use scrapers. It depends how much you want the grain to 'pop out', I suppose. I don't think you get chatoyance with orbitals.

A random orbital sander cuts across the grain.

No unperturbed flat spacetime then anywhere?

We are talking about technical issues, not human ones.

Slight correction, it is the fifth transaction, regardless of time length, although it does seem to be more random now when you are prompted to PIN. The cases you cite are examples of exploitative social engineering, rather than inherent technology flaws, I think.

That figures.

Right. Does that mean the US is slightly behind us then in applying newer security technologies? I'm not sure handing your card to a service person is standard practice here. They come to you with portable chip and pin units. You are more often than not filmed in any transaction you undertake in a commercial premises. I had my card stolen last week. I know the staff in my local supermarket pretty well and they said any transaction is fully traceable.

In the shops, not every time, around every fifth time you use a card scanner it will ask you to key in your PIN. That limits how much can be stolen. £100 is the maximum you can pay flashing your card without using your PIN. These limits are across all banking institutions. I think any changes have to be government approved iirc. In online transactions there is a 3-digit number you add as evidence you are in possession of the card.

Going alternately perpendicular probably helps the job go quicker.

Here's a lesson when positive action becomes discrimination. The whistleblower was a female RAF Group Captain:

If you do that, it isn't necessary to go to a full polish, I think. I like an in-line satin finish.

For polishing to mirror, after you've been through the grades, Jeweller's Rouge (iron oxide) or cerium oxide paste or powder

Found this little factoid from one of our UK police forces: Most of this technology is American, so I imagine the risks, or not, are the same as in the UK/Europe.

I have a one-speed grinder, which I want to change to to variable speed water-bath type. I want to match the speed to the item as think it will be safer and less likely to scorch the metal.
