First, I’ve written about this before but it keeps happening. Why why WHY do people feel obliged to update the data dictionary. That has to be the most reckless thing I can think of anyone doing or suggesting – unless it was support (and they had development ‘bless’ it). It happened again today – someone asked how to update the ALL_DIRECTORIES view (it wouldn’t update, thankfully). Why? They wanted to change the path a directory pointed to. I was very thankful the view wasn’t updatable – explained that DDL is the only way to modify the dictionary. Said “don’t go there”. Unfortunately, they figured out DIR$ is the table underlying the view and updated it. Sigh. I cannot understand why this happens. It is the reason asktom got started, someone suggesting a dictionary update. I will never understand the mindset that thinks it would be OK to do this.
On a lighter note, remember punch cards? In high school, we loaded up the card punch, punched our code into it (Cobol and RPG) and mailed them downtown to be compiled (not making that up, mailed them downtown). We would get the compiled listings back the next week. You made darn sure things were going to be as perfect as possible. It made you program differently, that is for sure – no typing in and seeing what sticks. You wanted it perfect the first time around. Well, today someone related an MP3 in terms of punch cards. They calculated how tall the stack of punch cards would need to be to hold a 3 minute MP3. Turns out that I would be able to hide behind the stack (if it were wide enough, it would be just tall enough).
Lastly, I stumbled upon these three very cool optical illusions. I agree with the comment on that site that illusion 3 is the most incredible. Very cool, you cannot believe what your eyes see all of the time. Seeing is not always believing!
Oh, I’ll add a fourth thing, just downloaded RH 4.0 and will be giving that a go. Doing a trial install in vmware right now and if I like what I see, I’ll be rebuilding my server with it tonight. I got the kernel, I got it compiled, but I ran out of time trying to boot with it last night. Thought it might be easier just to go to version 4.0
