Kexec is fine but I think the NMBL folk (https://fizuxchyk.wordpress.com/2024/06/13/nmbl-we-dont-need...) found that some hardware doesn't really like being initialized by the kernel twice (or by two different kernels if you prefer). This hardware or the drivers is written to assume that the kernel only boots once between resets.
Im not sure about initializing twice problem, sounds more like FUD to me. it is possible to leave computer as is for next kernel even with "whole memory allocation intact". maybe problem for "soft restart", but not for using linux as bootloader providing NVME boot capability usecase.
you can literally tell linux kernel - make my cpu XYZ look like cpu ABC... and everything works fine. [this was possible even before AI chatbots were a thing (ai joke sorry)]
yes, it can flash new "bios" from USB in case of bad update. this function is inate to intel "chipset" so every motherboard with direct to "chipset" connected usb port can recover bad update.
but you need to have usb flashdrive connected for long time, like 5 minutes or so, after powerup, without leds blinking so it can be scary / confusing.
The ROMs on these old boards typically don't have the driver needed to speak NVMe. Can't load your kernel if the UEFI doesn't know how to talk to your drive. This patch adds a driver to the ROM that allows it to natively access NVMe drives as block devices, solving the problem. Newer boards don't have this issue since nowadays it's standard practice to embed NvmExpressDxe or a similar driver from the factory.
imagine building CPUs with "remote epitaxy" so much manufacturing parallelism we could achieve. i know it does not work like that. but that, should be in scifi movie, not traveling thru wormholes. (not sarcasm)
Computer SSD can hold more books than all books you ever saw in your life.
saw, not read, saw in movies, saw in photographs, saw in magazines. all that can fit into your SSD
So just make freaking daily journal. there is plenty of space. You will be surprised what everything you did forgot. you will be surprised how your brain worked few years back. etc etc
And computer can hold more and retrieve faster then any other mechanism.
Also most wealthy people i know have their own "CRM system", where they note contents of phone calls, meetings etc, it is even easier with current state of AI/ML transcription services. They note names of children, spouse of their business partners. Hobbies, life situations, birthdays.... and they WILL look you up, right before you enter their office for joint meeting, so they can have conversation with you...
same as hardware hacking on "conferences" - they make you go with them on 2 hour journey of unlocking something, just for you to realize after doing some of it by yourself, that they can just download firmware update from manufacturer and run BINWALK utility on it, it will spit out filesystems, which you just mount, and read from that how is everything configured, how things work, what version of linux kernel they use.... so it is just hacking of YOU. it is advertisement, marketing story. XD
i used standard chain link fence on top of my small greenhouse and it works even with such big "holes", no mechanism, just manual labor but needs good forecast which can be issue.
I'm intrigued. Can you expand more on this? Why does it work? I guess because the hail is rarely coming straight-on at the holes and instead makes more glancing blows off the wire?
In any case I think it's a perfect example of a good hack. Original out-of-the-box thinking producing an effective but unconventional solution. Chapeau bas!
i saw chicken wire used for something unknown to me on top of old 1800s greenhouses in France. it was not used for hail because it was resting directly on top of glass. i do not know what it was there for.
but hail and flying debris i got past few years is so big and so frequent that im not sure chicken wire will do the job.
a lot of gardeners use shading cloth for lowering sun light intensity. but that is not always enough to withstand hail.
A lot of times there is multiple pieces of hail stuck in one hole. some just bounce off.
i have PV on roof and not had issue with that. but i had few broken glass pieces of greenhouse glass. even tho it is on same property. it is glass-glass bifacial, i did not do it for back light but for longevity, i saw too many plastic backing tear off, or delaminated or how to call it. so i did not want that. and im not sure if that is also factor in not having broken PV.
doing it on huge PV areas should atleast be by my feeling too much of hassle, investment.
But some people mentioned in other comments small arrays of, if i remember correctly, 5kWp. so that is roughly area im doing it on. so in those small arrays it can be done manually.
well, makes goats not eat precious plants so if it can withstand them, then hail will be ez. XD
(neighbors goats. i do not like animals, too much worry and work around diseases. there are tens, some years even hundred millions of chicken burned because of avian flu, pigs have african swine fewer,.... no thank you, corona cave bats of 2019, was enough for me...)
big desktop cooler for example Corsair A115 can cool 250W TDP under 40db
for sandy bridge XEONS - 2/3 of CPUs were under 100 w TDP, all of them were under 150W TDP
