  • Around the turn of the century I built a “middleware” layer for an Oracle to MySQL bridge which enabled legacy systems to keep running while modern and open source tooling could be built.

    The biggest challenge was moving from columnar to row based data … that and compiling Solaris tools using Oracle libraries.

    Oracle is like sendmail, user friendly, just very picky whom it makes friends with.

    I’m getting flashbacks to debugging an Oracle connection file.









  • Writing software is about problem solving skills which improve with practice. Often the process involves breaking down a problem into smaller pieces and breaking each of those down, until you know how to “solve” each problem.

    Writing down each “solution” and stringing them together is then the actual “programming” part of this activity … which brings with it a whole new layer of “problems” to “solve”.

    It’s as much art as it is accounting and the more you do it, the better you get at it.

  • Here’s some questions:

    • What happens when you die?
    • What happens if your house is burgled or catches fire?
    • How do you protect against pe(s)ts making themselves at home in your server?
    • What happens with a power or internet outage?
    • What happens with hardware failure?
    • What happens if you suffer dementia?
    • How are you dealing with AI bots?
    • How are you mitigating hacking attempts, security, authentication and exploits?
    • How are you dealing with data corruption?
    • How do you mitigate against ransomware having entered your systems?

    Note that I’m not picking on you, nor is this list comprehensive or in priority order. I’m trying to determine if you’ve considered these common issues and concerns associated with hosting stuff that has great sentimental value, if not actual value.
