Comment: Simmilar experiences ... (Score 4, Insightful) 251

A friend of mine lost his job over a simmilar "automation" task on windows.

Upgrade script was tested on lab environement who was supposed to be exactly like production (but it turns out it wasn't - someone tested something before without telling anyone and did not reverted). Upgrade script was scheduled to be run on production during the night.

Result - \windows\system32 dir deleted from all the "upgraded" machines. Hundreds of them.

On the Linux side i personally had RedHat doing some "small" changes on the storage side and PowerPath getting disabled at next boot after patching. Unfortunate event, since all Volume Groups were using /dev/emcpower devices. Or RedHat doing some "small" changes in the clustering software from one month to the other. No budget for test clusters. Production clusters refusing to mount shared filesystems after patching. Thankfuly on both cases the admins were up & online at 1AM when the patching started and we were able to fix everything in time.

Then you can have glitchy hardware/software deciding not to come back up after reboot. RHEL GFS clusters are known to randomly hang/crash at reboot. HP Blades have sometimes to be physically removed & reinserted to boot.

Get the business side to tell you how much is going to cost the company for the downtime until:
- Monitoring software detects that something is wrong;
- Alert reaches sleeping admin;
- Admin wakes up and is able to reach the servers.
Then see if you can risk it.

Listen, lad. I've built this kingdom up from nothing. When I started here, all there was was swamp. All the kings said I was daft to build a castle in a swamp, but I built it all the same, just to show 'em. It sank into the swamp. So, I built a second one. That sank into the swamp. So I built a third one. That burned down, fell over, then sank into the swamp. But the fourth one stayed up.
An' that's what your gonna get, lad -- the strongest castle in these islands.

Here's a better one-chip sollution:

MicroMite.

PIC32 running a full BASIC interperter (ANSI X3.113-1987, with optional line numbers, structured programming features like do loops, multiline if statements, user defined subroutines and functions. )

You don't even need to install Arduino or another IDE to use-it - you just need a VT100 terminal emulator and use the built-in editor.

I recommend MMBasic on a Maximite

Quoting from http://mmbasic.com/ :

MMBasic is a free and open BASIC interpreter for 32 bit microcontrollers.

It includes floating point numbers, extensive string handling, multi dimensional arrays and structured programming features like do loops, multiline if statements, user defined subroutines and functions.

MMBasic is generally backwards compatible with Microsoft's MBASIC and implements much of the ANSI Standard for Full BASIC (X3.113-1987).
