Indeed. Sure, lawns do have their place, like for playing sports or for kids to play around. But otherwise, what a waste. Just plant some local flowers or whatever and have a meadow. As an example, at some point my father stopped bothering

My uncle used a semi-DIY lawn mower for many years where he had replaced the original broken engine with an old electric drill. Worked fine enough.

RISC-V has certainly managed to avoid obvious footguns like delay slots or register windows. OTOH there seems to be a lot of people who think RISC-V went too far down the "RISC purity" rabbit hole, and that relying on the C extens

I tried to repurpose an old laptop I had lying around as a "lie on the couch and surf the web or watch youtube" machine. It was one of the last 32-bit only cpus (pentium m), so I installed Debian bookworm (12) on it. Unfortunately

RISC-V being an open source ISA does not imply that devices using that ISA won't be locked down. An open ecosystem in the way that historically emerged around the PC platform seems to be a completely orthogonal issue.

The history of China is perhaps not the history of AN empire, but rather a bunch of states/kingdoms, some of which every now and then managed to subjugate their neighbors and build an empire, for a while.

For all the faults of the NRC (real or imaginary), this still strikes me as an extremely bad idea.

Yes, but that comes from the telecom world. Hence thanks to NIH, that wheel must be reinvented.

There are some good theoretical arguments for such a structure, but OTOH experience trying to apply it on railroads hasn't been exactly positive. UK probably being the prominent example.

Looking at the diagram on the web page, seems the key is the water. When expanding, use heat stored in the water to heat the gas. Likewise when compressing CO2 into liquid, use the water to store the excess heat generated?
255.
by jabl 1y ago
I would say the big issue would be the size and cost of the gas dome. For storing a substantial amount of gaseous CO2 that will be humongous.

There is an additive called 6PPD added to tires to prevent them from degrading in the atmosphere, and it has been found that when this thing reacts with ozone in the air it forms another compound 6PPD-quinone which is highly toxic to some

The kilogram is no longer defined by a physical artifact, fwiw. Anyway, the point is the inconsistency in the system due to the kilogram being the base unit. So derived units are defined in terms of kilogram rather than gram. Say, the unit

Sorry, I was being imprecise. Rebuilds per se are no problem, as both MOFED and Lustre provide sources, and DKMS nicely automates rebuilding when installing a new kernel image. The actual problem is that RHEL minor releases would also break

Perhaps the cure is worse than the disease? There are several reasons to stay with a distro kernel: - Lustre releases target distro kernels, upstream would likely break. - Distro stays on top of CVE's etc. and provide updates when need

Yes, and yes. The kernel parts of MOFED are largely backports of the latest and greatest upstream kernel drivers to the various distro kernels their customers actually run. (The non-kernel parts of MOFED is mostly open source but does conta
