That is probably inspired by EN IEC 81346-2 where “X” indicates a connector of some kind and the numbers following the X identify the connector and the relative position on the connector (for connectors with multiple contacts).
Actually using AI gibberish for this might be the best strategy of all, since Reddit seems hell bent on making money with AI training and feeding AI generated text into AI training has been shown to yield increasingly worse results over time. So you make the product Reddit is selling less attractive.
ah ok i mistunderstood what the group head is. if they are both permanently in contact with the water in the boiler then it would depend a lot on the water quality. Water with only a little conductivity (<100µS/cm) would not be a problem for pure aluminium or most alloys, since the aluminium would passivate much quicker than the corrosion could dig into it.
i would assume that a vessel made for boiling water is made of a highly corrosion resistant alloy but i can not know for sure.
but that only happens while there is water there, right? so given the limited amount of contact time i think this is not a concern. aluminum has a great capacity for self-passivation too, at least the typical alloys do.
So what do you think when you work with HeLas?
centigrade
and he was doing so well until this abomination 😡
Do you mean oldest as in invented the longest time ago or oldest as in that specific technological artefact that i use is the oldest one i have?
For the first one i guess cooking?
For the second one its definitely my microwave oven, made in 1991.
expensive pharmaceuticals
antiretroviral meds are getting very cheap though, so not sure if that is really a valid point anymore. https://en.wikipedia.org/wiki/Cost_of_HIV_treatment
There is a limit on the spacing of the colour bands though. If you want colours then you have to hit the spots where the correct phosphors are and this limits the usable resolution.
Unfortunately for you most tablets were created for business transactions like bills etc. This is fortunate for archaeology though because it means that there were a LOT of them and it also gives us a pretty good view of what ppl. back then spent their money on.
So it still uses a MSDOS partition table, interesting. This usually only happens on systems that do not support EFI at all.
Is your BIOS and main board fairly old per chance?
Ok, that looks like a fairly standard setup. I guess taking a look at the boot loader itself would be the next step. When you see the Debian bootloader you could try pressing ‘e’ to view what commands it uses internally to boot. The lines starting with “linux” and “initrd” would be most interesting.
Hi, it would be useful to know what kind of device you are installing on. For a laptop the model and make would be especially useful. If it is a PC then the drive configuration would be interesting (what kind of drive, how many etc.)
Nope, not compression tech. The Einstein refrigerator is an absorption refrigerator and these don’t use compressors.
Librarians are trained to disseminate many different kinds of information and find relevant or related media and publications, because that is literally their job. This skill can be very useful in finding relevant info for checking a news story.
So, i read the “Red Mars” trilogy. I also keep up with research into the Martian atmosphere, its soil and geology.
My take is that all of this is still a pipe dream as much as it was 30 years ago when we did not know many of these things.
People don’t want to see just how hostile Mars is to life. They pick a couple of the most obvious problems (e.g. radiation, no liquid water, no oxygen) and then they look for the first solution that seems viable and then declare Mars somehow liveable because look we can just implement those things.
But they are completely ignoring that: none of these proposed solutions have been implemented at scale yet, at least not outside of earth’ atmosphere, there are hundreds of other known problems that often just don’t make it to the head lines because they don’t look that interesting or threatening (example: dust is suuuuper deadly on Mars, probably even worse than moon dust) and many problems will undoubtedly only become obvious once living beings are on the surface of Mars.
I am glad that there is hard sci-fi dealing with some of these problems in very optimistic ways, because we should try to better our understanding of them and not just give up, but we also should not have any illusions about how hard this task is and that this can take centuries of work.
Most modern operating systems randomize the MAC.
[citation needed]
having the option to randomize the MAC is not the same as actually doing that. There are also a few downsides to random MACs, like captive portals not remembering you on public WiFis.

basically since around the 1960s bombers dont need to “drop” bombs anymore. They only designate the target and the FCS drops the bombs.
