  • 1/2 a Life of IT predictions: Some hits, and some misses.

    crystal ball

    As of the other day, I’ve been a UNIX or Linux admin for exactly 1/2 my life.  That’s 23 years of UNIX or Linux hacking. Can hardly believe it myself.   Anyway, in all those eons, I’ve made some predictions. As one would expect, some were spot on, some were close, but not quite, some were … well … yea, I missed.

    Sometimes my friends and co-workers made predictions.  One of the more interesting …

  • The Dark Mystery of Time and Space

    alien invasion

    80 years ago, Orson Wells radio broadcast of War of the Worlds broadcast.  Legend has it that it produced in such a way to appear to be a real new cast and people supposedly panicked wildly.   Accounts of what happened vary.  But there were even congressional hearings over it.

    Whatever really happened that night in late October back in 1938, it certainly left a legacy.

    This is my favorite adaption of War of the Worlds …

  • That time when I accidentally crashed all the cash registers at a local grocery store.

    cash register

    It was sometime in mid-‘98 to mid-‘99 while I was working for the ticketing company.

    I had designed the new ticket printing outlets for a local grocery chain.

    It would allow customers to walk up to the costumer service windows at these stores and buy tickets to events at the local playhouse and several other venues and special events that the company sold tickets for.

    I was also the installer, and Level 3 …

  • That time when I had a dream predicting catastrophe … That struck on Friday the 13th!

    the dream

    During the week leading up to January 12th 2012, I was working at the Printing Office.

    There was some issue with the Netapp boxes and Snapmirror working that the network team and myself had been working on.

    The network team had some ideas, but when I left the office on the 12th, it was still not working.

    I worked a so-called “Alternative Work Schedule” where I worked 9 hour days, and had every other Friday …

  • That time when the storage array crashed at the worse possible time, only for the vendor to later denied it even happened

    floppy disk

    It was during the Stanley Cup in the late ‘90’s.  Final game of 6, and the ticket company was the one who sold the tickets for the event.

    As walk-up and will-call ticket holders started getting tickets, the load on the storage array had gotten pretty heavy.

    A KNOWN hardware issue in the array’s single point of failure - it’s cache card - was tripped, and the Array crashed.  It actually was designed to …

  • That time when I caught a ‘hacker’ breaking into a Linux box at the Law Library

    computer at 11 oclock

    Sometime in early-‘94 at the Law Library, we had an ( then ) experimental Linux box.  It was a Dell PC with an early version of Slackware installed.

    It was in the office, and I was just sitting there playing around.

    At the time, I was still learning UNIX commands.  So I was playing with the infamous finger command.

    And then I noticed someone logged in that was NOT authorized.

    Now, I say I “caught” a …

  • The Ghost of Mark, the UNIX sysadm … Deleting users!

    server room of horrors

    Back in the golden age of podcasting, Friends in Tech, a production company for podcasts, produced a few specials for some holidays. The first two of which, released Halloween 2005 and 2006, were The Server Room or Horrors and The Server Room of Horrors 2006.

    Halloween pranks, printers printing by themselves, mysterious SCO UNIX systems, coffee drinking zombies, and the ghost of Mark, the UNIX system admin.

    I present them here for your listening pleasure …

  • SSD, LVM and you: Zero data loss, LVM caching, and properly configuring your Linux box to get the most out of SSD!

    Tux

    I recently upgraded tesla, my primary Linux desktop, to one of the new Ryzen processors from AMD.

    So far it’s working very well, and the performance is sometimes even rather stellar.

    One of the big performance boosters, in addition to the Ryzen CPU and doubling the memory, was I went SSD in a big way.


    Now, it’s important to note, that I have a rather large music collection and some videos, a crap …

  • That time when a computer literally caught on fire!

    government shutdown

    So it was during the government shutdown in October of 2013, which was an odd time.  Fortunately, I was among the lucky ones who got to work, which meant I was guaranteed to get paid, which was good since I was a contractor. The deal for government employees was actually pretty controversial. The trains were running, but on the limited ‘S’ schedule ( while my train line was, I think others ran on normal schedules ).  AWS …

  • An email server in Lightsail: it’s harder than it sounds!

    UPDATE as of 2021-09-18: A few details changed since the original was written. This has been updated to reflect those changes.

    lightsail

    While it’s a little complicated, and takes fair bit of work, setting up your own email server with lightsail can be done.  And it’s pretty cool to have your own email server.

    There is a fair number of prerequisites that need to be done before this will have any chance of actually …
