AIX Operating System

 The AIX (Advanced Interactive eXecutive) operating system is a series of proprietary Unix operating systems by IBM. It's based on UNIX System V with 4.3BSD-compatible extensions and was the first operating system to have a journaling file system, with continuous enhanced features such as processor, disk and network virtualization, dynamic hardware resource allocation, and reliability engineering. The Common Desktop Environment (CDE) is AIX's default graphical user interface, with open-source KDE Plasma Workspaces and GNOME desktop also available.

SMIT is the System Management Interface Tool for AIX. It allows a user to navigate a menu hierarchy of commands, rather than using the command line. The F6 function key generates the command line that SMIT will invoke to complete it, while the smit.script file automatically records the commands with the command flags and parameters used, being useful to rerun system configuration tasks.

Smitty also refers to the same program, though it invokes the text-based version, while smit will bring up an X Window System based interface by searching for the DISPLAY variable. Failure to fire up the x window system will instead present the text interface.

Object Data Manager (ODM) is a database of system information integrated into AIX, akin to the registry in Microsoft Windows. Data managed in ODM is stored as objects with associated attributes. Command-line utilities such us odmshow, odmget, odmadd, odmchange and odmdelete allow for interaction with ODM. ODM is stored on disk using Berkeley DB files.

running red lights is now rampant

I have noticed that reckless/murderous driving is at an all-time high. During March 2020-late 2021, driving where I live ebbed, and when people drove in that period they quickly got used to clog-free roads with no coppers on them and drove accordingly. Now that traffic is back to normal, they have not tightened up their driving and are running red lights, impatiently making right turns without looking and ignoring pedestrians crossing, doing U turns dangerously everywhere all the time, cutting corners by driving through gas stations at high speed, etc. It got so bad I started over the last few weeks seriously looking at who is doing this in my neighbourhoods. Most have tinted windows, so those are the usual suspects. They drive like fiends. This is a big deal for me because I don't own a car and walk on heavily travelled streets and roads every day. There have been times in the past where cars hit me but they were slowgoing and low-prowed and I rode up on the hood with no injury or police-legal-hospital-insurance involvement. The vehicles now are tank sized with like 4 or 5 feet grilles and they drive them like they're sports cars and they'll roll over me without the driver even knowing.

handling failure is like handling success- you should always keep the momentum going

We're all more or less cut from the same cloth. The only difference between men (and between our better selves and definitely our lesser selves) is what we do when things look bleak. Do we succumb to the bleakness and spiral further into it? Or do we pull ourselves together and fight through it, finishing the story on our own terms?

It's not always a clear choice. You can have a "bad decade".

One thing I've learnt is to go towards what scares you rather than away from it.

To put it another another way, there is more pain in avoidance than in action.

To put it yet another way, when you come to a fork in the road, take the side that will grow your nads.
