SLIDES.EXE Opening Screen Slide Management: SLIDES.EXE is a photo slide manager that keeps a database of all your slides listed in alphabetical order or numbered order (or combination) in one (usually) or several databases. A description of each slide (80 characters) is shown in an editor so you can add, delete or modify entries. A help popup window is always available by pressing [F1], as seen in the picture of program screen. The list of slides, after you enter some, can be searched for key words or combinations of key words, which if found are highlighted. The searches take less than a second even for several thousand slides. Another feature is that you can enter a word processor and make a slide show by sequencing a list of slide letter-numbers separated by commas for a particular seminar. You may have up to 999 of these slide-show talks. The program also can make a list of these slides plus short descriptions if desired and allows you to enter the time in seconds that you expect the slide to require in a talk. The program makes a running total time (in minutes and seconds) as you update the times for the slides. The list is automatically updated whenever you change the slide-show file in the word processor.

Fallen Norway spruce near Torsby, Sweden Animation: FLASH.EXE is a program system for teaching that makes and presents computerized flashcards (slower flash rates) or animation sequences (faster flash rates). The flash rate can range from once per 5 minutes down to many times per second. On a 233 MHz Pentium in DOS it was possible to view 40 images per second from the hard disk. The sequences of pictures are made from *.PCX images with an enclosed program called PCX-13.EXE. Using the converted images and textfiles of these names, the program FLASH.EXE reads and shows the images for specific times. A sequence of 40 images that repeat is included as an example (showing what a flying bark beetle might view while travelling toward an infested fallen tree and then leaving again). 185K partial animation?

Netscape view of Expert Quiz Expert Quizzes on the Internet: HTML and JavaScript web pages interactively pose questions at random with multiple choice answers. Questions are ranked for difficulty based on prior student tests. During a quiz, the system tracks the percentage of correct answers and adjusts the difficulty of questions appropriately. A compiled BASIC program (QUIZMAKE.EXE) allows teachers to make specialized web quizzes from text files of questions and answers, without the need to know HTML, JavaScript, and BASIC programming languages.

HEARING.EXE tests your hearing for higher frequencies from 18000 Hz down to 40 Hz (hope you can hear something before you get to 40 Hz). A program that is fun for everyone, and can be helpful to know when you are not hearing so well due to clogged ears, age (unfortunately), or some other reason (like damage from music). Program requires only the pc's speaker. Download: HEARING.ZIP 37K


REFLEX.EXE tests your reflex speed from when you either see a white spot on the screen (eye to hand speed) or hear a peep (ear to hand speed). They should be similar if not identical. Compete with your friends or yourself. You could cheat but it is not easy since the start is random and false starts are not allowed. Still you might once in a while "jump the gun" but you can't do it very often. Download: REFLEX.ZIP 37K Test your reflexes on the Internet

Mineralogy - Geology: GEO-CARD.EXE - This program is for geologists (mainly those specialized in mineralogy). I made this program for my Dad who retired from the US geological survey (USGS) at age 65 and again from Los Alamos Nat. Labs. at 75. Now he is doing service work for them by looking at sample points on a microscope slide with a thin section of a rock. He identifies which minerals are present at the points to determine what kind of rock and geological formation the thin section is from in order to make geological maps (by USGS) or for other purposes. Earlier he used cards to record the data and had to add up the values manually, so I made a program that would print up the cards, act as a dedicated spreadsheet, and maintain a database on the rock thin-sections.

Software for DOS/Windows 3.1 or 95. The ZIP files must be unzipped before use.
To uncompress *.ZIP files you must have PKUNZIP.EXE or UNZIP.EXE. After downloading you must be in DOS and type:
pkunzip geo-card.zip
or whatever the name is. Download: PKUNZIP.EXE 29K - or you may download my general setup program JB-SETUP.EXE 50K which will install any of the program systems here.

PEDIGREE.EXE Opening Screen Genealogy: PEDIGREE.EXE - A program for showing your pedigree, or direct line of your ancestors. For example, you have a mother and father (yes you do) and they each had a mother and father etc. etc. The number of ancestors doubles each generation backwards, e.g. 2, 4, 8, 16, 32, 64 etc. so you have 32 great great great grandmothers and an equal number of great great great grandfathers (I hope). If you or someone in your family have done genealogical work, as my mother did, then you can enter all your ancestors names, births, deaths, and other personal information into a database. The program allows one to explore the relations graphically (actually as a text screen that appears as a graphic screen) using the cursor keys. The percentage of genes that you and a distant anscestor share is always calculated (let's get things in perspective). Notes can be looked at for each ancestor and these can be updated in a word processor of your choice. A calendar shows the birth, marriage and death dates of your anscestors and the appropriate day of the week (e.g. born on a Friday 1 OCT 1920, yes that is the correct day). A companion program can take a database called a *.GED file made by the program PAF (Latter Day Saints, or Mormon church) and convert it to the database used with PEDIGREE (or you can enter all the data manually in the program).

COMBINATIONS- COMBI.EXE can show and make a file of all combinations of up to 100 things in any size groups up to 100. For example, it can show all combinations of ABCDE (5 things) in groups of 3: ABC ABD ABE ACD ACE ADE BCD BCE BDE CDE. Also, permutations (order is important, so ABC, ACB, BCA, CAB etc.) and all possibilities (even AAA, AAB etc.) can be listed, but only up to 100 things in groups of 6 maximum. The program was upgraded to handle up to 100 ASCII characters (A to ñ) on 1 June 2000.
