### Broken images

HJG 2015-05-20: There are a lot of wiki-pages with broken images,because external links have expired (many of them from user gold). Does the wiki have a way to check for this, and make a list ?gold1may2016,Thanks for your help in restoring offsite images. I'm going to cut many of my references to offsite images. Can't easily retrieve some images and not sure images add that much. I'll restore my offsites into onsite WIKI storage, what I can. Would like some posted (approved consensus) specifications or suggestions of image type (png or gif) and usefull byte size on the how_to page. Since have seen arguments on use of jpegs and fuzzies on TCL WIKI. There are some search key words that will pull the older images.

AMG: Please note that in this Wiki, spaces at the beginning of the line interfere with proper formatting.

What is the meaning of your "#start of deck" and "#end of deck" comments in your code examples? And why do you need a plural set of the comments at the start and end?gold Like i said, I'm an old Fortran programmer. The multiple start and stop statements including subroutine stop and return statements were used in scanning big reams of Fortran code with 10E5+ lines. I can tell you that obvious stop,end,and return statements are helpful in that size of code. Come to think of it, I have seen lots of TCL wiki code with out end statements, obvious exit paths,obvious return statements, and graphic displays without exit buttons. The advantage of the wiki is that people can cut and paste what they want to use.Ah, I see. Also, consider that maintaining a consistent code indentation and spacing can help immensely when scanning a block of code, and not just at the start and end of the chunk. Compare the before and after code look here: Example Linear Interpolation CalculatorMuch of the wiki code is examples, and many times keeping an example focused on the example, without extras, makes for a clearer presentation. As well, modern GUI's provide out of band exit methods (the X in the mswin title bar, etc.) such that a lack of an exit path and/or exit button does not result in an unrecoverable situation. When the OS already provides a default "exit method" to every running program (and one or more out of band "kill" systems) there is less of a need to include an explicit exit in the code of each program.

aspect The amount of code you're pumping out in here is impressive, and I find some of the topics very interesting, but I'm finding the presentation less than useful. A few pointers, which I hope should be of value to yourself as well as anyone reading (and considering contributing) to your pages:

- Try to keep the wiki content example-focussed. Having multiple versions of the same long program in one page is distracting and confusing. If you need an online repository for your code I'd suggest using http://github.com/ keeping the wiki page for interesting extracts others can learn from or comment on.
**Please**be consistent with indentation and formatting! Your code will become much more readable to others and easier to maintain for yourself. The Tcl Style Guide (start with the linked PDF) is a good place to start.- Wherever you can, breaking out shared functions into a separate library script that can be loaded via source (or better yet package require), will make the library more solid and the main program more readable.
- If your explanatory commentary can be moved closer in the page to the code it concerns, that will also aid readability. Use inline comments (#) or the "if 0" trick -- an example is diff in tcl

- a set of labelled boxes for user input
- a "Solve" button which calls your main logic with the inputs as arguments
- a few "Testcase" buttons to illustrate examples and test the code
- "About", "Clear" and "Exit" buttons

namespace eval linear_interp { set name "Linear Interpolation Calculator" set inputs {"First X value" x1 "First Y value" y1 "Second X value" x2 "Second y value" y2 "Solve for x" xx} set about "This is Gold's linear interpolation calculator, © 2011 .. with some more information on how it works and is used, etc" set testcases { {10. 10. 200. 50. 123.} # etc } proc calculate {x1 x2 y1 y2 xx} { return [expr {some magic here to calculate the result}] } } load generic_calculator_gui.tcl generic_calculator_gui linear_interpAs a secondary advantage, your calculator could then without modification be used in other contexts, such as a command line or web tool or automatically invoking all the test cases. Of course, the GUI can also be easily re-skinned to the user's preferences without impacting the main code.I hope you don't find the above overly critical or discouraging, that's certainly not my intention -- but I do think keeping the above points in mind will make your pages more appealing to other wiki'ers and encourage collaboration .. which is what we're all here for, after all!

In some of the Sumerian literature, the constants for gold are called tube of gold or kus of gold, which possibly refer to a wire or rod. The Sumerians were experts at gold wire jewelery and used wire etc for trade in the early days. For example, the gold constant was 1:48 or decimal 108 in unspecified units. From modern estimates of density, a gold rod of 1mm diameter about a cubit (50cm) would have 0.15158 modern grams per cubit or 0.904 gin per cubit. There were about 8.3 metric grams in a Sumerian shekel or gin. Prospective formula is alpha times circumference squared equals 2 sila. sexagesimal 4:48 or decimal 288 is reciprocal 0;0,12,30 or decimal 12/3600+30/216000. alpha*circumference squared eguals 2 sila. height is circumference * sqrt(thickness/alpha) 1mm diameter silver wire of one cubit length .7854 * 10.5 gm/cc = 0.08246 gm/cm 0.08246 gm/cm, mass/length 0.08246 gm/cm (1gin/8.33grams) (49.7 cm/cubit) = 0.491 gin/cubit or sexagesimal 0;30 gin/cubit 288/6300=0.04571 gin/nindan 12*288/6300 equals 0.548 gin/cubit constant has units nindan*nandin/( volume in sar) formula is area*density=mass/lengthIn some of the Sumerian literature, the constant for gold are called tube of gold or kus of gold, which possibly refer to a wire or rod. The Sumerians were experts at gold wire jewelry and used wire for trade in the early days. Several remaining tablets give coefficients for the metals and the thickness of coefficient. For example, the gold constant was 1:48 or decimal 108 in unspecified units. From modern estimates of density, a gold rod of 1mm diameter about a cubit (50cm) would have 745.75 modern grams per cubit or 82 Sumerian grains per cubit. Normally the Sumerians measured gold, silver, and electrum in shekels or gin. There were about 8.3 metric grams in a Sumerian shekel or gin. The thickness of log coefficient is sexagesimal 4:48 or decimal 288. The reciprocal thickness of log coefficient is 0;0,12,30 or fraction 12/3600+30/216000, or decimal 0.003472 . An ancient math problem ref. Thoureau Dangin helps define the log thickness coefficient on a cylinder as the thickness of log coefficient (alpha) times circumference squared ( 0;25 or fraction 25/3600) equals the answer ( 2 sila). From inference on the math problem, the units of alpha are sila/(nindan*nindan) or volume per length*length. This method sets up a reference unit on the cylinder such that one nindan of the cylinder length approximates 2 sila. For example, the ratios for a half nindan length would be 1/2 nindan/1 nindan is as 1 sila to 2 sila. This method would have a possible use in breweries, a nindan stick and the circumference of the vat could used to find volume in a vat of beer. Continuing further with other uses for the thickness of log coefficient, the volume per length times density or mass per volume gives mass per length. Dividing the thickness constant by the gold constant gives the gin per unit length or gin per nindian. Multiplying by twelve gives the gin per cubit.Although subject to interpretation of Sanskrit text, the Sanskrit number words were used in Vedic formulas which are prologues to the atomic theory. #developed from instances of zero/error handling in the calculators on this TCLwiki.For example, an attempt to divide by zero will produce an error (1/0). In numerical analysis, erratic conditions can develop from subtracting a set of nearly equal numbers or very small numbers approaching precision limits (1.002-1.001 or 0.00002 - 0.00001 or [1.002-1.001]/[0.00002 - 0.00001] ). If divide by zero is a problem error, sets of numbers may contain zero values or numbers that approach zero value from the negative side (eg. 0.0001,0.0002,-0.0001,0.0003). Also, clipping,quantization, or reduction of real numbers may produce zero. values ( eg. 0.0001 at precision .02 clips to zero).Errors can be avoided using control ps for testing division by zero, offsetting numbers from zero, deleting zeros from sets of numbers, or atleast warning the operator that the calculations are approaching erratic conditions.For the push buttons, the recommended procedure is push testcase and fill frame, change entries , push solve, and then push report. Report allows copy and paste from console, but takes away from computer "efficiency".In planning any software, there is a need to develop testcases.

#### Testcase 1.

operation result 1/0 Inf, defined as error condition here 0/0 0/1 zero, defined as correct TestcaseThe Indian astronomy texts of 620 CE. used multiple Sanskrit words for zero (and numbers 1-9). The Sanskrit aternate words for zero were kha,ambara,akasa,antariksa,gagana,abhra,viyat,nabhas,sunya,bindu.The Sanskirt word sunya (void) is more common in the online wordlists. In transliterated Sanskrit , the decimal number 1000 could be expressed as left to right (0001) viyad(sky or zero)/ambar(atmosphere or zero)/akasa(space or zero)/eka(1). #Trying to find some earlier estimates of atomic theory from other cultures. The Svetasvatara Upanisad of Vedic literature indicated an atman was one ten thousanth of the diameter of a human hair, expressed as (1/00)*(1/100). or 10-4 .A human hair averages 80 microns or 8E4 nanometers.An atman would be 8E4/1E-4 or 8 nanometers. Since an insulin molecule is 5 nanometers and a hemogoblin molecule is 6 nanometers, an atman of 8 nanometers compares to human molecules within an order of magnitude.Possibly, the Sanskrit word atman (soul) was derived from atman (breath) and in some texts the root word ama (mother) seems associated or used as meaning soul. The Sumerians used oil films in bowls for divination purposes under tutoring of gods Enhil, Enki, and Ea, ref WG. Lambert (Enmeduranki,pg115). Early reference to atomic theory in English.It is as easy to count atomies as to resolve the propositions of a lover. Shakespear,As You Like It " 1590 CE. This Shakespear quote is believed to be derived from the Roman Lucretius, 20 CE.

"Oil Molecule Dimension Calculator "There are coefficients for concave square figures, which are of uncertain shape. These coefficients of transverse length 1 and area coefficient 0;26:26 or 0.43988. For a unit circle inscribed inside a unit square, the total area of the bits in the four corners is (area of square) - (area of circle), 1*1-.5*pi*.25*.25, 1-0.78539, decimal 0.2146. For a possible area formula, area is constant*transverse*transverse, 0.43988*1*1 or 0.43988 area units. Hence, eight of the corner bits or 2*0.2146 or 0.4292 would be closer to the formula result. Other coefficients and possible other geometric figures refer to short transverse of 0;33,20 (decimal 0.5555) and long transverse of 0;48 (decimal 0.8) with an area constant of 0;53,20 (decimal 0.8888) and a concave triangle of 0;15. For a possible area formula, area is constant*transverse*transverse, 0.8888*.8*.8 or 0.5688 area units. If a generic formula for is N1 * s. transverse * l. transverse equals area units, then rearranging terms gives N1 equals s. transverse * l. transverse / area units. N1 = 0.5555*0.8/0.5688 or 0.78. The simple shapes such as triangles, rhombus, and trapezoids usually have a factor of 1/2 involved. One can factor out 0.78 as 1.56 * 0.5 or even (pi/2) * 0.5 for a semicircle. What about an hourglass figure with 2 back to back concave?Some of the ship constants range from sexagesimal 0:05 to 0:12 or decimal fractions 5/60 to 13/60. The reciprocal constant for the Akkadian long ship (elippi or elonga type) was listed as 0;07:13.The ship constant times ship length cubed gives ship volume. The ship constant times ship length cubed times density gives ship mass (eg. cargo mass).In planning any software, it is advisable to gather a number of testcases to check the results of the program.

pseudocode: enter ship length,ship constant,density pseudocode: ship constants of 5/60, 6/60, & 7/60 fractions pseudocode: answers are ship volume, cargo mass pseudocode: go/ no_go condition (7/60)* [(ship length)**3] = 0.1166 cubic units (7/60) *[ 1 cubit**3] * 740 kg/[cubits**3] = 74 kilograms If cargo mass is greater than ship b., flag go/no go .

#### Testcase 1.

The trading ship hull has a length of 18.3 meters, beam of 3.96 meters, and a body height of 1.82 meters. With normal loading, the draw is 0.914 meters and the freeboard is 0.914 meters. The displacement is 30,000 kilograms with a hull weight estimated at 10,000 kilograms. The float or potential cargo is 20,000 kilograms. The surface area of the deck was estimated to be 46.4 square meters. The perimeter of the entire deck was estimated to be 44 meters. The arclength on one side of the deckship arclength is 22.65 meters or 45.57 kus, which was used in Sumerian calculations. Allowing for crew, spare consumables, and equipment at 8,000 kilograms, this is believed to be a "20 gir ship" with a cargo of 12,000 kilograms, 6000 liters (= 20 gir units), or 12,000 rations of grain. The normal ship crew is 30 rowers, 4 steermen, and 3 officers for a forty day cruise. Two rowers each are assigned to a 20 foot oar. Also, there are 2 steering oars at the back of the ship. Under oars alone, the trading ship has a speed of 6000 meters per hour. Under sail alone and ideal conditions, the speed is 160 kilometers per day or average 6600 meters per hour. However, the trading ship is rarely under power at night.0.5*18.3*3.98=36.4 sq meters deck area 36.4 sq. meters radius figure 12.727922 meters ship arclength is 22.65 meters or 45.57 kus. trading ship is 64 gurs by modern rating formula. liter wheat = 0.78 kg liter barley = 0.62 kg constant*sq. deck area = silas? 7/60 * 371 * 371 = 16058 silas, 16058 silas * 1 gur/300 sila = 53 gur 95 sq.cubits*95 liters sq cubit/300 liters/gur =30 gurs

#### Testcase 2.

The grain storage ship has a length of 29.2 meters, beam of 9.7 meters, and body height of 3.96 meters. The deck area of the grain ship approximates 0.5*29.5*9.7 or 143 sq meters. The grain ship arclength is 36.14 meters or 72.7 kus. The displacement is 245,000 kilograms with a hull weight estimated at 82,000 kilograms. The float or cargo is 163,000 kilograms. The storage ship allows for crew at 6,000 kilograms, spare consumables at 73,000 kilograms, and equipment at 48,000 kilograms. The storage ship is believed to be a "60 gir ship" with a cargo of 36,000 kilograms, 18,000 liters (= 60 gir units), or 36,000 rations of grain. The normal ship crew is 50 rowers, 5 steermen, and 5 officers for a ninety day cruise. Under oars alone, the storage ship has a speed of 4000 meters per hour. Under sail alone and ideal conditions, the speed is 160 kilometers per day or average 6600 meters per hour. There are 2 steering oars at the back of the ship. The grain ship hull has a length of 25 meters, beam of 6 meters, and a body height of 4 meters. With normal loading, the draw is 2 meters and the freeboard is 2 meters.grain ship: 58.4 cubits 935 sq cubits. 59.1 cubits long grain ship arclength is 36.14 meters or 72.7 kus. grain ship is 585 gur, by modern formula deck area of grain ship approximates 0.5*29.5*9.7 or 143 sq meters constant*sq. deck area = silas? sq cubits deck area 996.8*95literspergur*/300=315.4 gurs 88/.3 92.4690 sq. meters 25 meters =35 cubits deck area = 349 square cubits

(under proofreading) The research made some trial calculations with density of bronze from 1 )modern density values and 2) ancient density values from the Old Babylonian coefficients. For the modern density values in kilograms per cubic meters, the values were tin (7176),bronze (8189), and copper (8890). Using r1:1 as the copper:tin ratio, the generic formula was tin_density*(1/(r1+1))+copper_density*(r1/(r1+1)=bronze_density. Multipling (ri+1) term and substituting, 7176+r1*8890=8169+r1*8169, and combining r1*99.3=721. The alloy ratio r1 for the modern bronze density value was 721/99.3, 7.26. (under proofreading)In the eTCL calculator, kilograms are used with the price ratios of copper (1/90) and tin (1/20) for UrIII. From the trial calculations, these price ratios were transferred correctly to kilograms of silver. The price table contains redundant entries from different texts. However, the trade values or price ratios were undoubtedly different in different eras, countries, and texts.

### Schedule for the Gades brick piles, many assumptions

In some Sumerian contexts, the Giparu or sacred precinct was the residence of the en-priestess of the Moon god (Nanna or Ninnar), effectively a state cult for enthroning the king. The Giparu was the site of the Sacred Marriage Rite, probably conducted every year at various major cities. "pa4" is a Sumerian root word meaning priest; "gi6" is a Sumerian root word meaning earth or dark place. Sometimes, the en-priestess was the daughter or other kin of the king. In Sumerian, "en" means the king or shepherd. Also, successive en-priestesses or other offerings were buried under the floor of the Giparu. A later era calcite medallion of Enheduanna shows the Akkadian en-priestess conducting a threshold sacrifice. The medallion shows a triangular wall of 15 degrees face which would be called a buttress wall in modern terms.Locally in the Umma tablets , the local temple was called the Shara or Sara. The Sumerian word “Sar,Sa, or Sagina” is a root word meaning king, general, or royal officer in some contexts (ref. sag means head). The temple at Umma is sometimes referred as Sara on the quay, house of Sara, Sara of Umma. The temple was supported by the province of Umma and further received revenues and products locally. While not all the Umma tablets can be dated to the reign of King Amar-suen ( 2046-2038 BCE ), many tablets can be correlated by the local calendar of Umma, seals/names of the project personnel, and by personal names such as Ur-Sara (steward of Sara), Lu-Sara (man servant of Sara), Sara-mutum (woman servant of Sara. There was even a common beer called Sarazi (Sara Beer) and a common ration cereal called Sara-emmer (Sara Wheat).There was an Inanna temple near Zabalum. Men were normally forbidden in the temple (after consecration). Aside from the priestess there were about 60 women singers who served in the temple rites, but probably were housed on the dower estate of Girsana.The brick piles at Gaes can be placed in a tentative association with the events in the reign of King Amar-Suen. The associations are not really a formal history, but are culled from clay tablets on receipts, chits, and legal documents from the Ur III period. King Amar-suen came to the throne in 2046 BCE and the reign numbers refer to this date. The following individuals received a staff of high office:Akhuni, Ue-Enlilla son of the Elamite(?), Lu-Shara son of Urzu, Lu-ibgal son of Lugal-massu, the military governor, and Ur-Lisi, the governor of Umma province (no dates given). One tablet cites Lu-Shara as a scribe and another tablet as a hazannu official (mayor ). Lu-Shara was probably the mayor or administrative scribe under Ur-Lisi, in the reign of Amar-Suen. In Amar-Suen 1, Ur-Shara the scribe paid a credit for 19 copper sickles and 8 copper pickaxes. In Amar-Suen 1, the governor of Umma paid a credit for 170 male workers or about 5 workcrews for one day. Three promissory notes and two receipts on the Gades bricks were dated to the month of Akiti of Amar-Suen 4, mostly similar descriptions of the brick piles. Lu-sin accepts 33 sar of brick for the (moon?) temple and 10 sar of bricks for the military depot (marsa) storage house (no dates or specific location given). While not all the bricks can be established as fired, the fired bricks were probably intended as foundation bricks, underground dedication shrine boxes ,and high use floors/thresholds (ref. the Nimintabba temple at Ur and the Inanna temple at Nippur. Some of the fired bricks were probably used in rebuilding the Karzida quay in front of the moon temple. By custom, the buttressed walls of the en-priestess residence were exceptionally thick and the foundation under the walls was extra strong. In Amar Suen 7, The en-priestess En-Nanna-Amar-Sin-kiagra was installed at Gades/Karzida (for the first time). In Amar Suen 9, the en-priestess En-Nanna-Amar-Sin-kiagra was installed at Gades/Karzida (third time). The project was believed to be completed in the ninth and last year of the reign of Amar-Suen. The available data suggests the building or restoration on the moon temple was completed in 4 to 6 years.### Schedule for Gaes bricks, tentative and many assumptions

In one coefficient list, there was a coefficient for wool (igigubbum-hi-a) as 48 in a base 60 fraction (48/60). The term igigubbum is Akkadian, apparently borrowed from Su, igi-gub-ba ( I see fraction (used as reciprocal)). The term hi-a appears in URIII texts associated with wool and textiles, and means processed wool or processed fleece. In the Nippur lexical lists, the term siki al-hi-a was translated as processed wool (work). A math problem using the wool coefficient is not available, but will try to convert 48 in base 60 into modern decimal units and proportions. In modern terms, the equation is coverage area * reciprocal coefficient equals material. Starting with Sumerian units, the coverage area in sar units times reciprocal coefficient (60/48) equals weight of wool in gu units, simply sar*(60/48)=gur. Rearranging terms, the proportion is gu units/ sar units = 60/48 or sar units / gu units = 48/60. The proportions hold true if 60 /48 is reduced to 5/4, meaning 5 gus of wool equals 4 sar of woven cloth. 5 gu/4 sar equals (5*60*0.4977) kg/4*32 sqm, 1.166 kg/sqm, 1166 grams/sqm for wool cloth. This figure of 1166 grams/sqm is probably one weight of wool cloth and probably the Sumerians used other cloth weights also.For the clothing, its easier to use square cubits than sars. A sar equals 144 square cubits, and a gu equals 60 manas. So the 5/4 ration above would equal (5*60)/(4*144), 0.521, rounding 0.5 manas per square cubit. Or the reciprocal was equivalent to 2 square cubits per mana. The 2 mana ration to low status men would be equivalent to 2*2 or 4 sq cubits of woolen cloth. The 3 mana ration to craftswomen would be equivalent to 3*2 or 6 sq. cubits. The 4 mana payment to project overseers would be 4*2 or 8 sq. cubits. The child's garment above would be 3*2 or 6 sq. cubits. The high status female full skirt would be 3.5*2 or 7 sq. cubits. The tug-guz-za long shirt for the high statue male weighed 5.474 manas and was 5.5*2 or 11 sq. cubits. In general, the wool ration and the weight of clothing was a measure of status.

### Is Thales theorem easier to use ?

Dear uniquename, I noticed you referred to Thales Theorem in one of your posts. I have a question on the use of Thales Theorem by Old Babylonian mathematicians (circa 1900 BCE). By remainders and artifacts in base 60 problems and math coefficients, there appears to be one tradition of Babylonian mathematicians that derived formulas from Thales Theorem and one tradition of Babylonian mathematicians that derived formulas using Pythagoras or sqrt(sum squares). Apparently, the Greek Thales was of the former persuasion in a different era. Especially the dual use of Thales Theorem and sqrt(sum squares) is seen in the Old Babylonian coefficient lists (base 60), ref. Eleanor Robson paper on coefficient lists at Oxford. Supposing no computers or slide rules, is the Thales Theorem easier to use than sqrt(sum squares)? Does the Thales Theorem produce numbers that are easier to factor in simple primes (2,3,5),use in pi multiplication, use in base 10, or surveying land (with equilateral triangles)? Old Babylonians are known to have avoided division and usually numbers 7 and 9 in math problems, as producing numbers difficult to factor in the base 60 system. My email service is erratic lately, please post your reply at the end of my tcl wiki homepage, thanks gold### Gaming solutions or false positions with eTCL calculator

It is possible to find solutions to equations using the method of false positions (regula falsi) or gaming with the eTCL calculator. Suppose a coating of some known thickness is applied on known surface area and one wished to estimate the coating coefficient. From an initial solution either from the testcases already loaded into the calculator or from order of magnitude calculations, the coating coefficient can be estimated from a series of guesses or false positions in incremented steps. The accuracy of the coefficient solution depends on step size and is usually given as half step size (0.5*step). For example, the solution if found in the series <1, 1000, 2000, 3000, 4000,5000> would have a accuracy of plus or minus 1000/2 or 500. Loosely speaking, this is operating the eTCL calculator in reverse. Finding the coefficient that gives a solution of specified input (2 sides of a surface area) and specified output (volume).This is the gist of an Old Babylonian (OB.) math problem for water irrigation, converted to metric units from clay tablet YBC4186. A cubic water cistern of L/W/H 60/60/60 meters was used to irrigate a square field to a depth of 0.015 meters. The volume of the cistern would be L*W*H, 60*60*60, 2.16E5 cubic meters. What are the dimensions of the field, assuming square field? In terms of a modern algebraic equation, the answer was field area equals L*W*H/D, 60*60*60/0.015, 14.4E6 square meters, or 14.4 square km. Each side of the field would be sqrt(14.4) or 3.8 km. To initialize the eTCL calculator, press testcase 1 and push solve, returning the first test case solution. In the length and width fields, enter 3.8E3 meters and solve should return the correct surface area (14.4E6).Continuing with the OB. water irrigation problem, it is possible to game on a eTCL solution for the coefficient (not in the OB. solution or outside the OB. text). Loading and solving for possible test solutions (regula falsi) as (coefficient = 1000, 2000, 3000, 3500, 4000), the coefficient in the test problem is close to 3400.RLE (2014-05-20):You have the following statement in almost all of your pages:

- Report allows copy and paste from console, but takes away from computer "efficiency".

for {set i 0} {$i < 10000} {incr i} { for {set j 0} {$j < 10000} {incr j} { lset matrix $i $j [ expr { [lindex $matrix $i $j] * [lindex $matris $j $i] } ] puts "$i $j [ lindex $matrix $i $j]" } }This (made up) numerical computation loop above iterates 100,000,000 times. The result is it runs puts 100,000,000 times, which will slow down the loop because puts has to do output (lots of other code to execute to ultimately achieve the "output" operation). Removing that puts (or commenting it out) would speed up that loop by quite a large amount.Also, note that while debugging, sometimes running a puts inside the inner loop to see intermediate results can help you locate a bug or a math error.But there is a difference when it comes to output of results to a human (or another machine). At that point, you have little choice but to perform at least one puts (assuming you appended your result together beforehand). For an "output of results" routine, the point is to perform

**output**, so running puts is not reducing "efficiency", rather it is the whole point of the output routine.With that said, if you were doing something like outputting one character at a time of the result, with a puts per character, then yes, that would have been inefficient.So the "gripe" was most likely not a blanket "this applies to everything" statement, it was much more likely a "given what you have here, you are being inefficient" "gripe". The difference is important. It seems you may have over-generalized the "gripe". gold Text on console puts and efficiency mostly pulled from my wiki pages, 22may2014

Alternate English translations by William Scott Wilson in “Life Giving Sword” and Thomas Cleary in “Book of Five Rings” desparately need a glossary for common definition of terms. I have supplied a starter glossary for “Life Giving Sword”. As a common ground between east and west, a Romanji equilvalent text on shujishuriken (paraphrased) terms would be useful. I hope others can make contribution to meaning of shujishuriken and other terms in Life Giving Sword. If we can not build the whole bridge, we can add a few blocks.Glossary of Yagyu-Ryu terms and words in Yagyu Family Memorial text (c. 1632 CE) . Terms below are from 17th century text, not necessarily same as Modern Japanese usage. Takuan Soho, Yagyu Munenori, and Miyamoto Musashi used homonyms, puns, or specialized terms, which are not found in conventional Romanji dictionaries. Romanji dictionaries contain homonyms, which are words that sound the same but have different meanings. Special combined terms in martial arts (Buddhist traditions) are noted by capitals, hyphens, or quotes. bo: wooden staff bocuto: wooden sword bokken: wooden sword, usually heavy wood for exercise. chi: vital energy, or broadly energy from earth and sky. Sometimes in Japanese texts by extension, chi or ki refers to manifested chi or force. The manifested chi in Chinese texts is called jing (muscular power), jinli (martial power), or jin ( combination of emitted chi and muscular power applied to a specific target spot). daiki taiyu: divine transformation. Usually, transformation from potential or resting energy to active motion and force. human, or heaven in Chinese philosophy. chudan: sword held in middle position gedan: sword held tilted down ha: attack hachimaki: headband hakarigoto: "strategy" hakama: pleatted skirt or culottes, usually worn for exercise. hara: navel or belly heihou : “strategy”, literal “dark hidden deception” hiro: color ho:martial art hyori: deception inka: martial arts diploma isshin, “One Mind” isshin itto, “One Heart, One Sword” kan: listening with mind and contemplative insight. ken: sword or used as homonym for “plain sight or ordinary sight” as opposed to contemplative insight (kan). kendo:way of the sword kenjutsu : swordsmanship. kannen:mind should see through one’s emotions or mind should be clear of emotions. kizen:”take initiative” jo: preliminary attack jodan:sword held above forehead kage-ryu: shadow sword style, sometimes refers to following, reacting, and basing actions on opponent’s shadow. Especially, staying outside opponent’s cast shadow until closing for attack. kami: shinto diety or dieties kanshin: seeing with mind or insight. katana: long sword. katsu: refers to attainment of essential nature or “Life-Giving” katsujinken: “Life-Giving-Sword”, sometimes refers to resolution of problems without force. ken: sword kenshogodo: seeing into essential nature. ki: vital energy kiai: focused shouts, loud scream used to disturb opponent. koku: empty space kyusho: vital point kuji: 9 hand signs or mudras used in kendo training. kyu: counter strike majutsu, techniques of invisibility mondo: question and answer in Zen dialogue. mu: “Non-existence”, sometimes refers to Yin side (left) of opponent or hidden side (shadow) of object. mu-kyu: “Non-existence counterstrike”, sometimes refers to circling counterclockwise (in Yin direction) around opponent for one or more paces and attacking the “Non-Existence” (left,Yin) side of the opponent. Here, “Existence” may refer to sword held by right handed swordsman and “Non-Existence” may either refer to empty hand on left side or the palm of the right sword hand viewed from the left (by the opponent). munen muso: (literal) No-Desires, No-Thought muto: “No-Sword”, sometimes refers to resolution of problems without force. Also techniques of unarmed combat. munen: “No-Thought” or refers to actions under suspension of consciousness. mushin, "No-Mind", suspension of consciousness, usually during meditation. mushinjo: suspension of consciousness, usually during meditation. myo (na) : strange, odd, without reason naginata, long spear with heavy blade. nakazumi: “mysterious-sword” is holding sword around navel or hara. nitto ryu: “two-swords-style” ryu: sword style or school satori: "enlightenment" setsuninken: “death-dealing-sword”, sometimes refers to solving problems by force only as opposed to solving problems without force. satsuninto: “death-dealing-sword”, sometimes refers to solving problems by force only as opposed to solving problems without force. seiza:kneeling position for meditation practice sensei:teacher shin: mind shinken: “Real-Sword”. shinken sho-bu: contests with “Real-Sword”. shinku: emptiness of mind shinmyo: “Mysterious”, refers to the combination of mind (shin) and strange outside action (myo). Usually found in combination as “Mysterious-Sword” or implied sword. shinmyoken: “Mysterious-Sword” , refers to the combination of mind (shin) and strange outside action (myo) holding the sword (ken) around navel, just as hara is considered center of being/energy. suigetsu, literally moon on water, refers to keeping 3 pace distance from opponent or out of opponent’s cast shadow. Note: sun and moon both cast shadows. shuji: crosspattern sword block (literal from Sino. characters, hand ji (noun suffix)). Sometimes refers to crosscounterpoint target on body of opponent. shujishuriken: (literal from Sino. characters, hand ji (noun suffix) hand inside see) perception of abilities and intentions. By extension, see inside technique of opponent. Sometimes refers to the 9 healing sounds and ideographs (mudras) used to increase alertness, warmup shoulders, and loosen hands prior to combat. tachi: great sword tsumeru: deflection or block leading to counterstrike. not a hard block. yang: positive energy or active principle . heavenly energy. clockwise movement. yin: negative energy or inactive principle. earthly energy, counterclockwise movement. tai: substance or fundamental property of all things tao: way of philosophy wakizashi: sidearm sword or short sword yari: spear zazen: meditation practice zen: meditation practice towards Self-Realization Katsujinken, “life-giving-sword by Yagyu Munori,C. 1632 CE”.Heiho Kadensho of Yagyu Munenori.Also known as Yagyu Family Memorial text in paraphrased Romanji terms, kk kk k lll jjj kkk bbb bb nn nnn mmm mmm mmm mmm

From a clay tablet, internal and external volumes of a hollow cylinder is equated to squared ratio of radius1*radius1 over radius2*radius2. Not sure about the accurate math derivation and maybe numerical coincidence, but the tablet appears to be using inner volume equals outer volume times radius1*radius1 over radius2*radius2. Hereafter, the paragraph will use the modern decimal notation, PI (3.14...), and carry extra decimal points from the eTCL calculator, whereas the Sumerians used 3 and round numbers. radius1 would be the radius of the hollow and radius2 would be the radius of the outer cylinder. In the tablet, the circumference of the outer cylinder was 1.5 units and the ratio of the inner radius to outer radius would be 1:4. The diameter of the outer cylinder would be 1.5/PI or 0.4774, and radius2 would be 0.4774/2 or .2387. radius1 would be .2387/4 or 0.0597. The height of the cylinder would be 1 unit. Using conventional formulas the volume of the outer cylinder would be 2*PI*radius2*radius2*height, substituting 2*3.14*.2387*.2387*1, 0.3578. The conventional volume of the inner cylinder would be 2*PI*radius2*radius2*height, substituting 2*3.14*.0597*.0597*1, 0.0224. The volume of the hollow cylinder would be outer cylinder minus inner cylinder, 0.3578-0.0224, 0,3354. In squared proportions, the radius1*radius1 over radius2*radius2 would be (1*1)/(4*4),1/16,0.0625. The Sumerians found the inner cylinder vol (hollow) as (1/16) * outer cylinder vol, (1/16) * 0.3578, 0.0224 in modern notation. Not on the tablet, but it follows that the hollow or outer cylinder volume would be (1-1/16)* outer cylinder vol, (15/16)* 0.3578, 0.3354.In Sumerian base60, the factor would be 1/16 or 3/60+45/3600.

Several Babylonian tables of powers have been published. Some of these tables are equivalent to even powers of prime numbers. For example the table of nines would give numbers, equivalent to even powers of 3. The table of 16 would give equivalent numbers based on even powers of 2. Conjecture is that these tables could have been used to generate Babylonian triplets. Ref, Babylonian Pythagorean Triplets by Michael Fowler.
