• Pattern Matching

  A pattern cut with a laser JMP's pattern matching functions can do almost everything regex can do and a little bit more. Internally, regex is built from the pattern matching functions and sports an easy-to-use interface. You'll probably never need the little bit more, so if you have experience with regex, it might be a good place to stay. Or, you might find the pattern matching language more attra...

• Sunshine Map

  ( reminds me of Cover the Earth  Sherwin Williams Paint (XXH0284) - R.C. Maxwell Company Outdoor Advertising - Duke Libraries )   The attached JSL file (below) does not use the time zone from the previous post. (But it will, in a post soon.) For now, just capture a set of images to make the animation.   There are a lot of web sites describing how to do this. They all seemed complicated, so I trie...

• HeatColor vs Spline vs Interpolate

  Mapping available colors onto a response: you can use a color theme built in to JMP, or you can build a custom mapping with tools in JMP. You'll have to write JSL to use a custom mapping; it won't be a theme. Using a built in theme: the HeatColor function maps a number between zero and one into a color. This example uses two themes, "jet" and "spectral", and makes the following picture.   New Wind...

  Around 1960, before ZIP codes, before shopping malls, Grandmother shared a telephone connection with several other people on a party line.The Telephone Company supplied a distinctive ring for each customer, and please don't listen in, it isn't polite. This was in the capital city of North Carolina, 90,000 people. Within a few years she was the last one on the party line, but The Phone Company was ...

• Can I make ASCII Art with JMP?

   ASCII is the name of one of the original character encodings. A character encoding maps numbers into character shapes; the number 65 is a capital letter A in the ASCII scheme. ASCII only allows for about 95 printable characters and is very US-centric. But at the dawn of computing, before pictures were invented, there was ASCII Art. Often printed on a Teletype on yellow paper, JMP is going to use ...

• Working with WAV files

  I've made several projects using audio in different ways: midi files, speech api, calling a windows DLL, and reading/writing WAV files. This time I'll be working with WAV files again. JMP's BlobToMatrix and MatrixToBlob functions to operate on blobs (Binary Large OBjects). LoadTextFile and SaveTextFile know how to read and write blobs. A WAV file is a binary object (you won't get much joy opening ...

• Third Branch 4K Video

  4K video!  4K means 2160p 3840x2160, which is really just twice as big (in X and Y) as 1080p 1920x1080.  (You'll need a 4K display to see the high res version; YouTube will present a lower resolution for most of us.  Still looks great.)  This video was made from a series of 2D images of a 3D model saved from JSL.  The attached JSL files build a branching structure out of spheres and send the camer...

• Web site wants a password

  Question from @billkopp. Using cURL to supply basic authentication credentials.  Replace "user" and "pass"  appropriately.  Remove the -k if you don't need it; it bypasses the checking for a valid signing authority on an https site's certificate (you probably know if you are using a self-signed certificate...then you'll need it).  DO use https if available; it will keep others from seeing the pass...

• There's a Hole in my Bitmap

  The JSL below creates two bitmaps: a rainbow-colored background and a Mandelbrot shaped mask.  The two bitmaps are added to a graph and the rainbow is moved around under the mask.  It's very fast because the bitmaps are only created once and the OS provides support for the mask's transparent hole.The transparent hole in the mask is created with the alpha layer, which is similar to the red, green, ...

• Wireworld Computer

  I just discovered the 20-year-old Wireworld computer, which appears to be just a picture.  It's much more than a picture.  Its a functional piece of art that calculates prime numbers.  It's a description and implementation of a computer.  It must have been a labor of love for the folks that created it.From the picture I learned about one choice for the only instruction in a One-Instruction compute...

  I wasn't sure where this project would go.  The attached JSL script (below) generates images to a desktop folder (create it first) that can be combined into a video using other video creation software.  I used Blender's NLE; there are packages with shorter learning curves.Making no apologies for the script, it was a work in progress, and then it was done.There is something happening in the first 7...
