Channels had to be built, etc, etc. The client gave me a ‘NO WAY’ that it can take that long, they need to move in at the end of the week plus maybe two days... There is a method to the madness. When the power is done, the plugs can be mounted, in turn the cabinets can be populated, etc. When you work out of order, you end up with things that need to be done afterwards. This is not ideal. Also, every project has a gremlin, hidden somewhere waiting to jump out at you - and you need to make allowances for that too. In this case, the basement was locked and no-one had a key or access. Obviously, the current power cables ran through there, forcing us to build other paths. This is why I like recipes; when I use a cake recipe, I never end up with soup. You know your system, you know your workflow. When something breaks, follow a reasonable “recipe” for problem determination and repair. Ask yourself, what changed lately. If nothing had, it may be a hardware issue! Something as minor as a bubbling capacitor in a power supply may cause an issue down the line. Go with what you know, before trying something exotic.** |

**Q: I was once considered somewhat of an ARJ God. I preferred this over LZH, LHA, Zoo, HAP, PAK, ZIP, etc, etc. My question is, just how safe is ARJ today? My query stems from the fact that I no longer know who owns and distributes this (it’s available from more locations than I consider it should be), and, now being a Linux user, should I move to something more contemporary such as 7zip? The command-line use is admittedly similar enough - just curious. | **Q: I was once considered somewhat of an ARJ God.

A: The problem is the old display card. The Nvidia driver you need for that is 3.04, which is not supported in the new version of Ubuntu.
