NASA using Ruby?

ruby-talk
1

I noticed a reference in the intro blurb for Dave Thomas’s talk at OSCON to NASA doing numerical simulations using Ruby.

However, a number of quick googles have failed to find any mention of it. I expected that it might be in the Real World Ruby section of RubyGarden, but it’s not there, either.

Does anyone have any further information, or a URL?

Cheers,

Harry O.

IIRC, Bil Kleb was using Ruby to help
investigate the Columbia disaster. That’s all
I know about.

It caught the attention of David Alan Black and
me because he was using scanf. :slight_smile:

And David’s comment was, “Well, at least scanf
didn’t CAUSE the disaster…”

I’ve gone there on a couple of occasions to add an entry buy never
found enough gumption to follow through…

Sorry, I’ve let ruby-lang go unread for a while…

He may have been referring to myself and Bill Wood.

We’ve been using Ruby since 2000 or so when we did a prototype
Extreme Programming (XP) project. We developed a couple numerical
simulation prototypes using XP. The experience is written up in
the May-June 2003 IEEE Software magazine as well as the 2002
http://xpuniverse.com/ conference proceedings.

We have been using Ruby at every opportunity since.

Recently using http://www.googlism.com/ I found an IBM article which
mentions some of our work with Ruby:

http://www-106.ibm.com/developerworks/linux/library/l-oslab/

and it seems that we managed to not use the word “Ruby” in our abstract
that was included in the NASA’s Tech Briefs magazine announcement,

http://www.nasatech.com/Briefs/Dec02/LAR16494.html

which also describes how one can request a copy of our code and
inflate our local management by objectives metrics — read DeMarco’s
/Slack/ to uncover the inside joke… :wink:

I don’t know. Was there any foam used in the construction
of scanf?

Maybe. Linux has been in space quite a few times, including older versions of
Debian, Slackware, Flight Linux, and Redhat (RH6.1 was on STS-107). I
couldn’t find a list of what packages the installations used in these
missions used, though.

There should be a group at NASA that makes sure to inform each open source
project that is sent into orbit. :slight_smile:

Hack user friendliness onto a pure and simple system, because
you can’t hack purity and simplicity onto a user friendly system.

Take a look at Rite: it’s “up in the air”.

I’m told that XML actually originated in space (despite what you may say about
it’s SGML origins.) Yeah, it was an alien disease that came down in the
jacket of a cosmonaut. It started as a swarm of hovering ping pong balls and
later formed the noxious mist that we all breathe nowadays.

Okay, that was mean. I won’t do it again.

If it is true that XML is a kind of disease, would you go so far as to
say that it is “viral”? If so, isn’t it like the GPL?

Well, I would go that far, Lyle. But I am considering GPLing a strain of
barley yellow dwarf virus that can be encoded into XML and injected into
wheat. Sure, the plant dies, but the aphids will get a good taste of markup.
This will be a very advantageous to those of us who are willing to employ
aphids, but find that they often lack the experience.

Thanks for having a sense of humor :wink: I was just demonstrating that the
GPL is so viral that mere discussions of it on a mailing list or
newsgroup are able to infect other, nearby, threads of discussion.

This last link has really awesome pictures … where is this beautiful
place?
(sigh, cannot read the Japanese text around the pics).

By the way, these are pictures of Yukihiro Matsumoto ( a fairly common
Japanese name, I understand). Not of ‘Matz’.

‘Matz’ is like the French Mathematician Nicolas Bourbaki. Just a name
adopted
by a team of talented Japanese programmers. Cannot be one person.

Ok, so I was only kidding. Sorry Matz, could not resist :wink:

Park Heesob

Thanks, Park, for hunting these out.

My guesses would be…

Start off with a number of photo’s of Matz’ workplace. You can see that
the frosted office door has the name in English. “NaCl” (like
rocksalt).

Picture 10 is Izumo Taisha Shrine.
[http://www.kankou.pref.shimane.jp/e/must_see/taisha.html]

Pictures 11 - 19 are Matsue Castle.
[http://www.kankou.pref.shimane.jp/e/must_see/shiro.html]

Pictures 20 - 33 all appear to be at the Tamatsukuri Hot Springs, where
you can eat, take a dip, play video games.
[http://www.kankou.pref.shimane.jp/e/events/autumn.html]

He tours another side of Izumo before going home. I’m guessing these
are taken by Masao Kanemitsu, who has a number of Mandelbrot apps in
RAA?

Check out this regional map of Japan:
http://www.jnto.go.jp/eng/RTG/RI/index.html You’ll see that his trip
took place in the Shimane prefecture, in the Chugoku region.
Matz mentions going to church in Matsue on his blog and NaCl is in
Matsue, so I’m sure he lives in close proximity to all of the sights you see in
these photos.
