  • The new material has eight times better performance than pure cubic silicon carbide

    Nowhere is it stated how efficient either material is, other than to say that the researchers are 5-10 years away from a material that’s 10% efficient. So they must have an efficiency of less than that I guess.

    From the paper, the closest I can see is:

    The applied bias photon-to-current efficiency (ABPE) of the Ni(OH)2/Co3O4/3C-SiC photoanode reached 0.47% at 0.65 V vs RHE, which is 15.6 and 1.8 times higher than that of the 3C-SiC and Co3O4/3C-SiC photoanodes, respectively (Figure 4b)

    I don’t know how representative that measurement is though.





  • There are still opposite charges - each colour has an ‘anti’-colour. So R+R=colourless G+G=colourless etc. This is how mesons work (pairs of quarks). Baryons are triplets of quarks but there are also combined tetra- and pentaquark states also.

    You can think of anti-red as being cyan etc. but the colour theory can be more confusing than it’s worth.










  • In the System settings, under Window Management > Window Behaviour, in the Focus tab, there is a Focus stealing prevention selector. If it’s set to extreme, then it does prevent switching to another desktop when I open a window that gets sent there.

    I think that’s what you want but I guess it would mess with all applications, not just Steam. I don’t think you can do it per application.

    I remember there being a window management protocol that would allow more control but I don’t think Kwin implements it yet.





  • If you have the docker-compose.yml locally, you can nix run github:aksiksi/compose2nix to translate it into a nix file for inclusion in your nixos system config. I think that could be done in the config itself with a git url but I’m not that great at nix. You will surely still need some manual config to e.g. set environment variables for paths and secrets.


  • How do the DNS servers resolve local hostnames then? The pihole DHCP integration adds local hostnames to DNS when they are assigned an address. If there’s two DHCP servers handing out leases, presumable only one would be accepted, how then would the DNS servers sync those names?

    I think I had my secondary pihole resolve local names from the primary, and leases were copied over on a cronjob in case the secondary DHCP server had to be enabled.
