I was more suggesting that it might be a bit eldritch, but sometimes humor doesn’t come across quite right/

The linked paper is focused on studying the ‘perforation-type anchor’ they use to hold the tissue to the mold as it grows, rather than keeping it alive afterwards. During growth the tissue and mold were submerged, or partially submerged, in a suitable medium to keep the cells healthy, and it was only when the resulting models were tested that they were removed (although one test did seem to involve letting it dry out to see if the anchors held). Growing the various layers of cells seems to be a solved problem, and I suspect that includes keeping them supplied with nutrients and such, so the authors aren’t examining that. What’s not solved is how to keep the tissue attached to a robot, which is what the authors were studying.

Do you really want to know? There are some things that the human mind is not meant to contemplate.

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.

Putting a simple preseed file on a debian install image is probably going to be your best bet. Assuming you can run a VM on your current machine it shouldn’t be too difficult to test it until you’re happy with it.

It’s going to be a balance between your time getting an automated approach to work and the cost/effort of getting a monitor. Getting preseed working can be a bit fiddly, but it does mean you’ve learnt a new skill, getting a monitor sounds like it’ll be a pain, and you might only need it once.

Yes, that’ll work too, it does involve adding the disk to your machine temporarily though, so just be carefully which disk you format to do it. Please don’t ask why I say that, it brings back painful memories…

While I agree with most people here that finding a keyboard and screen would be the easiest option, you do have a couple of other options:

• Use a preseed file A preseed lets the installer run completely automatically, without user intervention. Get it to install a basic system with SSH and take it from there. You’ll want to test the install in a VM, where you can see what’s going on before letting it run on the real server. More information here: https://wiki.debian.org/DebianInstaller/Preseed

• Boot from a live image with SSH Take a look at https://wiki.debian.org/LiveCD in particular ‘Debian Live’. It looks like ssh is included, but you’d want to check the service comes up on boot. You can then SSH to the machine and install to the harddrive that way. Again, test on a VM until you know you have the image working, and know how to run the install, then write it to a USB key and boot the tsrget server from that.

This all assumes the target server has USB or CD at the top of its boot order. If it doesn’t you’ll have to change that first, either with a keyboard and screen, or via a remote management interface sych as IPMI.

Tried with ‘Connect for lemmy’ against lemm.ee and just got a full screen error that vanished after a second.

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.

Easier? Yes. More fun? No.

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.

Our troop bought in bulk them then handed them out to the scouts who earned them, there were no micro transactions involved.

I can’t say that I feel my past accomplishments bring me pain, each was as well done as I knew how, and brought me new knowledge, which is quite rewarding. The bar doesn’t raise beyond reach either, as you already know how to go as far as you have, and you’ve hopefully learnt a little more. You’re not always going to achieve your best results, but that’s where critiquing your performance comes in. You can inevitably learn something from it.

If you don’t need external calling you don’t need a trunk, it’s just for connecting to the outside world. I found [[https://www.asterisk.org/|Asterisk]] was a good place to start. The config is rather involved though, so there are various front ends for it.

You’ll never get it perfect, so I found it useful to reframe it as aiming to get as close as possible to perfect then giving yourself a fair critique so you kniw how to get closer next time. It’s sort of Zeno’s perfection paradox. You get closer each time, but never actually get there.

The difficult bit is to keep the fuel fusing. At the temperatures and pressures that are needed to get atoms to fuse together the whole lot wants to blow itself apart. Being able to reliability sustain the reaction for any length of time is a big achievement.

Once we can get it to keep going, then yes, we can use the excess heat for power, although it’ll probably involve turbines rather than an old school steam engine type setup.
