RISC-V is better for Linux due to driver support. Vendors making hardware are more likely to use RISK-V for their controllers due to the costs. Modern computers are putting more functions under control of kernels that run on proprietary compute. (There exists a chart showing how little the Linux kernel directly controls.) As more of those devices run RISC-V, they will become more discoverable.
Also, those that can design or program tge devices will have more transferrable skills. Leading to the best designs spreading, and all designs improving.
Places in a computer with compute (non-exhaustive, not all candidates for RISC-V):
BMC
Soundcard (or subsystem on mainboard)
Video card (GPU and the controller for the GPU)
Storage drives
Networking
Drive interface controlling card
Mainboard (not BMC)
Keyboard
Mouse
Monitor
UPS
Printer
Will it be perfect? Nope.
A lot of the vendors will lock things up as well.
Any good write-ups about Sega? I wonder what was happening financially.
Agreed, but Teens have lots of time. They are likely 90% of the audience.
You know, if the rules for government handouts were more open, another company could gain ground. Just pointing out something congress controls.
My guess as a Linux admin in IT.
I understand the fix takes ~5 minutes per system, must be done in person, and cannot be farmed out to users.
There are likely conversations about alternatives or mitigations to/for crowdstrike.
Most things were likely fixed yesterday. (Depending on staffing levels.) Complications could go on for a week. Fallout of various sorts for a month.
Lawsuits, disaster planning, cyberattacks (targeting crowdstrike companies and those that hastily stopped using it) will go on for months and years.
The next crowdstrike mistake could happen at any time…
Create a series of folders labeled with dates. Every day copy the useful stuff to the new folder. Every night change modified dates on all files to current date.
That and our sun engulfing earth prior to the moon reaching equilibrium.
With 20 TB drives, I would have concerns about a drive failure during a rebuild. I suggest at least 3 drives and a config that can handle 2 failures.
Unless everything is replaceable.
Thank you. It sounds spectacular and well thought out. You must work with a great team.
“Secret Bot” sounds great!
Custom in-house or off the shelf?
So many passwords will be in there. And cat photos.
“Easier” and “simpler” are in the eye of the beholder.
A different way to approach it is to limit the failure domains. If this breaks how sad are you?
I would separate storage from the rest. Networking stuff together may be fine. Home assistant depends on how dependent on it your household is.
The only people I have known with certs didn’t have educations. Generally, the fewer degrees, the more certs. There are exceptions.
If you have a PhD or Masters, then certifications are unlikely worth it.
If you don’t have a Bachelors, then certs are critical. Many jobs will just reject you.
A Bachelors is where certs seem to do the most good.
All of this in my part of the USA (Midwest and West) and speciality (HPC). I have been involved in hiring in several organizations.
I have not had an issue mixing and matching drives in a hardware or software RAID. Just needs to be at least as big as the previous.
I have had issues with non-vendor drives in Dell and/or HP systems.
(I am a pro, but not your pro.)
Sometimes having the problem removed is worth a lot.
Sometimes the time waiting for the professional is not worth it.
If it can be done for less than $200, I pay and move on.
I haved fixed several appliances which stayed working for years after.
It is a natural study. Just compare rates to those of nearby towns. Possibility very fast to do.
Back in the day one had to pay good money for that training data. Now the data frees itself.
The President can have the board killed. Might focus the minds of the next board. /s
Thank you for the reference link.
China has one hell of a note on that page:
