There’s an easier and more reliable way to limit replication; don’t hive them the means to create a small but essential part, and instead load the first probe woth many copies of it and have each replica take a set percentage.

For instance, have the probe able to replicate everything but its CPU, and just load up a rack of them on probe 0. Every time it replicates itself it passes half of its remaining stock to the replica and they both carry on from there.

The article says:

The photons travel through a resonant metasurface, where they mingle with a pump beam.

From that, I think it’s suggesting it needs a separate beam of photons to amplify the signal, much like a transistor needs a supply current to amplify the signal it gets.

They also say:

This new tech also captures the visible and non-visible (or infrared) light in one image as you look through the ‘lens.’

Which sounds like it produces an image showing both the IR and visible spectrum in the visible range.

Mind you, re-readind it, most of the article just talks about IR, so I’m not certain what it’s actually doing. It could just be transparent to the visible spectrum. It wouldn’t be much good for driving if it did that though, the windscreen blocks a lot of IR and you’d need IR headlights!

The material captures visible light too, so headlights would be brighter, but I wonder if there’s a way to reduce the contrast by either filtering out some wavelengths (like driving glasses) or the material simply not boosting it’s output past a certain level?

The device captures visible and infrared light, just like a typical night vision scope. They’re working on expanding the spectrum too, which could lead to some interesting and useful results. I understand that, for instance, skin cancers are more visible under certain UV wavelengths, so imagine a doctor being able to just put on a pair of glasses that convert that wavelength to give you a once over during a checkup.

It doesn’t really matter whether the FMR is one in a hundred or one in a million, for the uses it’s being put to it’s still too high. If it was only being used as one factor for authenticating someone (I.e. the ‘thing for are’) but still required the other factor(s) (the ‘thing you know’ and the ‘thing you have’) then it’d be adaquate.

As it stands, when it’s being used either to pick someone out without further scrutiny, or to make payments with no further checks, it’s simply unacceptable. There’s good arguments to say it’s not just the error rate is unacceptable, but that the technology simply shouldn’t be used in those scenarios as it’s entirely inappropriate, but that’s a separate discussion.

F-ing brilliant.

It’s the same problem with a drive like this, or any long term archive, you either store the data unencrypted and rely on physical security, or make sure you store the encryption key and algorithm for the same length of time, in which case you still need the physical security to protect that instead. In both cases you need to make sure you preserve a means to read the data back and details of the format its in so you can actually use it later.

Paper is actually a pretty good way of storing a moderate amount of data long term. Stored correctly it’s unlikely to physically degrade, the data is unlikely to suffer bitrot and it can be read back by anything that can make an image in the visible spectrum. That means you can read it, or take a photo and use OCR to convert it into whatever format is current when the data is needed.

That may be your perfect search engine, I jyst want proper boolean operators on a sesrch engine that doesn’t think it knows what I want better than I do, and doesn’t pack the results out with pages that don’t match all the criteria just for the sake of it. The sort of thing you described would be anathema to me, as I suspect my preferred option may be to you.

Hackers aren’t the only way to meddle in an election, just the easiest to categorize and deal with.

Maybe a good pair of headphones and the careful application of some spray paint? Mask and holes or areas you don’t want to colour, then apply several light coats until suitable pinkness is achieved. I suspect you’ll get bonus points for personalisation.

Depending on what sort of shirt it is, could you considered sewing an interesting patch over the area? Take a sort of ‘visible mending’ approach? That way it just becomes one more memory associated with the shirt.

A capacitor can’t ‘dump’ it’s energy any faster than tbe circuit attached to it can use it, as illustrated by Ohm’s law (ignoring the capacitor’s self discharge rate, which for a purpose like this can be kept very low).

With a low self discharge rate there’s also nothing brief about the length of time a capacitor can store energy. Think of it like a bucket with a small leak (self discharge rate). We’re adding water/energy to it each day (from solar panels or similar), and taking some out as needed. As long as the leak is small in comparison to the amount of water/energy being put in it’ll still be well topped up when you need it.

With regard to a crack, it sounds like that will just lead to a reduction in storage capacity to worst, if a chunk actually falls off. The carbon forms a branching network throughout the entire block, so just breaking some strands wont stop it being conductive. You’d definitely want to deplete it before working on it though, even a small cap can give you a nasty whack.

Keeping the energy thermal avoids a conversion step, and hence one area of inefficiency, especially as we use a lot of our energy for heating. There’s been some interesting progress on heat batteries which would pair well with a solar concentrator.

Just adding another voice agreeing that I just want to block instance posts, not comments from their users.

If people really don’t want to see anything from an instance then they should join an instance that is bit federated with the one in question.

If blocking all users from an instance does get implemented I believe it should be separate to blocking posts as they’re very different use cases.

Yes, connect lets you block instances, but it still shows that there was a comment there and lets you show it. It’s handy to see how much you’re blocking.

That’s the thing, ‘cloud’ is just another tool in your toolbox. It’s the right tool for some workloads and the wrong one for others. The fact they’ve shifted the work to their own servers and kept the ops team suggests it was the wrong sort of workload to be in the cloud in the first place.

For a while there was an obsession with moving everything to the cloud, and that was always going to be an expensive mistake in a number of different ways. Hopefully, as the hype dies down more nuanced decisions will be made. There’s a whole gamut of options between all in the cloud and all in the data centre, and when people jump straight from one end to the other I’m put in mind of Hamlet’s quote “There are more things in heaven and earth, Horatio, / Than are dreamt of in your philosophy.” Understand your workload, understand your business’ future plans and their needs, and then make a plan, considering all the tools at your disposal.

I’m mostly group 2, but I can ‘see’ simple things if I want to, although they’re somewhat ghostly in appearance. I found that drawing was a good way to start. Begin by drawing simple objects accurately, really focus on their shape and texture. That level of observation help you learn to really see things, rather than just looking at them. With that level of mental model it becomes easier to overlay or insert it into your perception of reality. With practice you get better at it.

Bear in mind that this is just my experience and I don’t have much to base it on except what’s worked for me.

Fair, stating a time-to-live when you’re paying might make some people think twice. At this point though, I think people need to just not be paying unless they get to keep it permanently. Paying for access to the online portion is fine, but the rest should keep working and you should be able to get your data out of the developer’s system.

If people stopped renting games developers would start selling them again. Until then, the incentive is for them to keep pulling this nonsense.

There’s a difference between a game having online elements, such as a MMO, and games that require a connection just so they can keep charging you. Even in the first case though, you should own the client, and ideally it either has a single player mode, or the developer releases the code for a basic server when they shut it down.
