Flowers 1.0

As the days warm up, the 2 windows to my room are open almost all the time, and the fan runs pretty continuously while I am there.  The hot water has been off for a while now.

I’ve had quite a bit of damage to the plants from caterpillars, so I have decided to do my first experiment.  Catch a caterpillar in the act, put it in a jar ventilated with screen or punctured aluminum foil, and then after allowing the caterpillar to sample all leaves, leave it inside with a vinegar-soaked leaf, a hand-soap soaked leaf, a coffee soaked leaf, and a lemon-soaked leaf, and a control, and watch to see the order in which the leaves are  consumed.  Still, I like caterpillars, they eventually turn into either butterflies or moths.  I don’t want to kill them, just deter them from eating my plants, and make them think weeds are tastier.

The exciting news this week-end is that my first morning glory appeared.

I took pictures like any proud parent, and set about writing a botany program.

I organized all my wildflower pictures into a directory named botany/botany pics on my device containing a new shell script program that I wrote named  This program is very heavily based on the following pdf file:…/1-BotanyBasics.pdf

In fact, before using the program, I would read the chapter.  Then on the first run of the program, fill in the blanks while reviewing the course material.  Finally, take and time yourself on the quizzes.

The program can run entirely as a bash.script on any unix system I think by simply entering n to all of the questions except using quotes.  I use Lucid Puppy 5.25.  The way that it is currently set up to run on Lucid is with a directory called botany, that contains 2 files and 2 subdirectories:

The first file general_botany_facts.txt contains all of the references to the chapter.

The second file  environmental_quotes.txt contains references I have found on the web to environmental quotes.

The first subdirectory called botany_pics contains jpg pictures that you have taken of the local flora in your area.  In mine, because I am just starting to garden, although 80% of the pictures are wild flora, I consider anything that I have “domesticated and grown” fair game for a picture.  The picture files should be jpg and sequentially numbered like: 01 dandelion.jpg, 02 prickly_poppy.jpg, 03 turkish_cap.jpg …

The second subdirectory called local_flora_facts contains facts found on the internet regarding each species in the picture files.  These fact file should be named 01 dandelion.txt, 02 prickly_poppy.txt, 03 turkish_cap.txt …

For music, I created an itunes music media subdirectory called flower music.  I put links to the 4 seasons by Vivaldi there.

Finally, in order to run the program you will need random1.c and intdiv2float.c compiled and running in the same directory where you have the shell script.

random1.c can be found on this page:

and intdiv2float.c from (it is called average.c there just rename it to intdiv2float.c when you copy it):


So, that’s kind of the nuts and bolts of getting it up and running.  What does the program actually do?

It enters a quiz mode, and times your answering of random questions based on the botany text.  If you get the answer right, it randomly displays a picture of a local flower, and then randomly displays a fact about that flower.  It also displays a random quote from high literature regarding the environment, and plays a 30 second section of Vivaldi’s 4 seasons while you look at the picture and read the quotes.  You then move on to the next question.

Sample output file sommaire.out looks like this for me using no pics, no music, no quotes … just the barebones unix programs.

You worked  16 minutes for an average of:  0.160000 minutes per question, and a sum of  100 questions.
The correct answers ( 88 ): , asexual, Opposite, fertilizer, Tunicate, Vegetative, pubescence, pistil, perennial, Tunicate, tendrils, maturation, Meristems, drought, shrub, germinate, taproot, maturation, organ, Rhizomes, cambium, bulbs, ovary, pubescence, tendrils, cambium, Xylem, style, perennial, summer, Cross, xylem, node, secondary, outside, elongation, bracts, elongation, roots, light, bracts, asexual, sessile, light, spiral, Leaf, bulbs, Rosulate, secondary, vascular, style, summer, axil, Leaf, hardening, dominance, hyphae, dicot, stamen, Fertilization, tendrils, taproot, Spurs, monocot, anther, blade, woody, internode, monocot, girdling, bulbs, sperm, self, tissues, axil, shoot, length, counter, dicot, fibrous, meristematic, Heartwood, fibrous, dicot, sperm, Opposite, twining, Dormant, ovules
The incorrect answers ( 12 ): , axillary, bracts, roots, taproot, Vesicular-arbuscular, Adventitious, tissues, Vesicular-arbuscular, palmate, xylem, petioles, flower
The database had  220 entries.
Your percentage:  0.880000


OK. That’s what it does.  What is the benefit?

Hypothesis: memory impairment can have several origins.

In some cases, stimulating and exercising memory may help to form new synapses, stabilizing or reducing memory loss.

This program would be a nice addition to retirement communities, addiction recovery communities, hospitals through social work intervention, etc.

As a home-schooling aid it allows students to gather and organize information about the natural landscape surrounding them, developing their interest and respect for it.  In this way, the program can be unique for each environment.  It provides a nice reminder for people who cannot visit a site all year round, and might be homesick and want to capture memories of it.  Nice as a gift to a loved one who can’t get out much anymore.

In terms of younger students, it can act on a few levels:

1) memory

2) reading and recognizing words, filling in the blank

3) learning how to deal with unfamiliar words

4) transitioning between rapid highly focused work, and relaxation

5) supporting exploration, novelty and response to novelty (the randomness feature).


So, here is the actual script.  Not as smooth as I would like it to be, I want to switch from xmessage to feh, and work on smoother transitions with options.

01c: I enter Shennongjia through Fangxian in the north.  Even now rumours are rife that there are Wild Men around these parts.  It is recorded in the late Qing Dynasty work “Annals of Yunyangfu” that in this forest running 800 li from north to south “all day long is the roaring of tigers and the screeching of apes”.  I am not here to carry out an investigation into Wild Men, but have come to see if this primitive forest still exists.  I am not mercilessly driven by some burning missionary zeal, it is simply because I have come down all the way from the high plateau and the huge mountains of the upper reaches of the Yangtze and it would be a pity to miss out seeing this mountain region of the middle reaches.  So not having a goal is a goal, the act of searching itself turns into a sort of goal, and the object of the search is irrelevent.  Moreover, life itself is without goals, and is simply travelling along like this. (Soul Mountain, p. 342, Gao Xingijian)
02c: Nature teaches more than she preaches. There are no sermons in stones. It is easier to get a spark out of a stone than a moral. (John Burroughs)
03c: Afoot and light-hearted, I take to the open road,  Healthy, free, the world before me, The long brown path before me, leading wherever I choose. (Walt Whitman, “Song of the Open Road”)
04c: Who didst establish the earth upon its foundations, that it should not be moved for ever and ever; Thou didst cover it with the deep as with a vesture; the waters stood above the mountains. At Thy rebuke they fled, at the voice of Thy thunder they hasted away– The mountains rose, the valleys sank down–unto the place which Thou hadst founded for them; Thou didst set a bound which they should not pass over, that they might not return to cover the earth. Who sendest forth springs into the valleys; they run between the mountains; They give drink to every beast of the field, the wild asses quench their thirst. Beside them dwell the fowl of the heaven, from among the branches they sing. Who waterest the mountains from Thine upper chambers; the earth is full of the fruit of Thy works. Who causeth the grass to spring up for the cattle, and herb for the service of man; to bring forth bread out of the earth, And wine that maketh glad the heart of man, making the face brighter than oil, and bread that stayeth man’s heart. The trees of the LORD have their fill, the cedars of Lebanon, which He hath planted; Wherein the birds make their nests; as for the stork, the fir-trees are her house. The high mountains are for the wild goats; the rocks are a refuge for the conies. Who appointedst the moon for seasons; the sun knoweth his going down. Thou makest darkness, and it is night, wherein all the beasts of the forest do creep forth. (Psalm 104)
05c: I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could learn what it had to teach, and not, when I came to die, discover that I had not lived. (Walden, Thoreau)
06c: Adopt the pace of nature: her secret is patience. (Ralph Waldo Emerson)
07c: The farther one gets into the wilderness, the greater is the attraction of its lonely freedom. (Theodore Roosevelt)
08c: I am glad I will not be young in a future without wilderness. (Aldo Leopold)
09c: The temple bell stops.  But the sound keeps coming – out of the flowers. (Basho, 17th century Buddhist poet)
10c: Today’s mighty oak is just yesterday’s nut that held its ground. (anonymous)
11c: He who is in harmony with Nature hits the mark without effort and apprehends the truth without thinking. (Confucius)
12c: Out through the fields and the woods And over the walls I have wended; I have climbed the hills of view And looked at the world, and descended; (Reluctance, Robert Frost)
13c: Humankind has not woven the web of life.  We are but one thread within it.  Whatever we do to the web, we do to ourselves.  All things are bound together.  All things connect.  (Chief Seattle, 1854)
