Top tools for junior Linux admins

cmake

www.cmake.org believe it or not... this make file generator is great for automating the configuration of linux. It has the ability to script, generate files from templates, a full suite of file manipulation commands, and to top it off integration with the tools ctest and cdash. Setup tests that confirm your desired configuration and then have those tests posted on a web based dashboard.

cmake- it ain't just for making make files .

[I acknowledge that there are better configuration management systems out there. BUT for those forced to homebrew their own for whatever reasons (such as no external internet connection because of security) this tool rocks. Not to mention you can find thousands of people who already know cmake.]

At 7:40 you see the balloon and parachute wrapped around the truss carrying the camera, etc etc...

Thanks again...

Balloon to Platform... twist of cable, string, and rope...

I know the balloon in going to spin and that wind will also cause LOHAN to impart more spin....

But i have been thinking about the spin since watching a number of the balloon videos available.

Would it be worth it to use some form of rotation resistent rope and/or a swivel between the balloon and platform.

If you do just go with a standard twine or climbing rope, it might do a bit of good to pre-untwist it by allowing LOHAN to hang from it overnight prior to launch....

LOHAN MUST FIRE... Before the balloon bursts... I forgot this other example

http://www.youtube.com/watch?v=zf1i2qyvei8&feature=endscreen&NR=1

at 7:40 you see great example of your chute and balloon wrapped around your wildly tumbling near MACH 1 falling LOHAN of death...

Fire LOHAN before that balloon bursts...

LOHAN MUST FIRE... Before the balloon bursts...

LOHAN MUST FIRE before the balloon bursts because the balloon and connecting cables will WRAP AROUND LOHAN before it gets off the rod....

-------------------------------------------

I direct you to this video http://www.youtube.com/watch?v=kAhaIDNVyC0

at 5:20 the balloon bursts.

at 5:33 the remnants of the balloon are shown WRAPPED around the truss which held their camera...

at 5:37 you see the horizon at 90 degrees and the bag hold the control circuitry at 90 degrees to the camera... ie. the truss is tumbling...

at 1:31 you see the small chute they had on the contraption to act as a stabilizer during descent...

at 5:55 you see it open and working it's stabilizing magic... the camera is now facing upwards again...

-------------------------------------------

LOHAN MUST FIRE before the ballon bursts because no chute can stop the spin of the truss in a short enough amount of time to fire LOHAN:

----------------------------------------------

In this video: http://www.youtube.com/watch?v=_00eZtsuJ9M

at 2:35 ice is shown flaking off the parachute... interestingly the metal can does not have any ice... What materials on LOHAN might ice up?

While this project's chute seems to have immediately stabilized the platform relative to the horizon, from 2:35 to 2:50 we see the a pronounced wobble which surely would cause LOHAN unhappiness whilst leaving the mighty rod...

Oh and one other thing... it is spinning like crazy...

------------------------------------------------------------------------

LOHAN MUST FIRE before the balloon bursts because upon burst the truss as designed will immediately fall forward (nasty gravity) and POINT DOWN allowing LOHAN to either fire straight down or just slide off:

-----------------------------------------------------

I direct you to this video of a contraption which was heavier in front of the camera... http://www.youtube.com/watch?v=ZCAnLxRvNNc

at 4:10 the balloon bursts and the we see an immediate pitch forward because of unequal weight ratios...

The inevitable tumbling begins....

In this video http://www.youtube.com/watch?v=zf1i2qyvei8&feature=endscreen&NR=1

at 4:14 the balloon bursts and the camera which was pointed UP... by 4:17 is pointed 90 degrees to the horizon and at 4:19 is pointed DOWN....

The inevitible tumbling begins....

FORGET THE PARACHUTE DEPLOYMENT GIZMO... I SAY THIS FOR YOUR OWN GOOD

Sincerely

Daniel
