  • 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.



  • 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.









  • NFS-Cache is a specific cache for NFS, and does not represent all caching that can be done of files over NFS. “Direct I/O” is also a specific thing, and should not be generalized in the meanings of “direct” and “I/O”.

    Let’s skip those entirely for now as I cannot simply explain either. I doubt either will matter in your use case, but look back if performance lags.

    One laptop accessing one NFS share will have good performance on a quite local network.

    NFS is an old protocol that is robust and used frequently. NFSv3 is not encrypted. NFSv4 has support for encryption. (ZeroTier can handle the encryption.)

    SSHFS is a pseudo file system layered over SSH. SSH handles encryption. SSHFS is maybe 15 years old and is aimed at convenience. SSH is largely aimed at moving streams of text between two points securely. Maybe it is faster now than it was.
