[racket-dev] Release Announcement for v5.1.2
The hopefully-final release announcement sketch is below. -- * The download page includes 64-bit installers for Mac OS X, Windows, and two Debian flavors. * Racket now includes a new `racket/place' library to support parallelism, complementing `racket/future'. Racket's parallel build process is now based on places instead of multiple OS processes. Places support share-nothing parallelism and message-passing communication. Compared to futures, places are heavyweight, but they have a simpler performance model. * The syntax-certificate system has been replaced by a syntax-taint system. Both certificates and taints were designed to protect otherwise inaccessible bindings from abuse when they appear in macro expansions. Taints are simpler and lighter, and the switch closes known holes in the certificate system. Macros that are not implemented with `syntax-rules' or `define-syntax-rule', however, must explicitly use `syntax-protect' to protect their expansions from abuse. * The `net/url' library supports HTTPS connections, but beware that by default all sites are accepted (equivalent to ignoring a browser's warnings about untrusted certificates). * The `for' forms now support an `#:unless' clause, and a nonnegative integer can be used as a sequence. The new `compose1' function creates single-valued composition functions. The `racket/function' library now provides `identity', `thunk', and `thunk*'. * Error messages in the student languages use a simplified vocabulary and consistent phrasings. If you maintain curriculum material or teachpacks then please consider updating. See the Error Message Composition Guidelines section in the documentation for details. * Typed Racket: almost all core Racket data structures and operations are now accessible in Typed Racket (most of this work is due to prolific contributor Eric Dobson). The performance of the typechecker has been significantly improved. * The `scriblib/bibtex' library supports BibTeX-formatted citation databases in Scribble documents. BibTeX can be tricky to parse, so please report failed entries as bug reports. * The license has been clarified: we now use LGPLv2.1 uniformly. (The license file used to specify LGPLv2, contrary to the download pages.) -- -- ((lambda (x) (x x)) (lambda (x) (x x))) Eli Barzilay: http://barzilay.org/ Maze is Life! _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev

[racket-dev] New plot library [Was: (to Jay) Re: What I'm working on]
Re-routing this email exchange to [racket-dev] for comments. Long story short: Jay roped me into replacing the current `plot' module by wrapping a plot library I was working on for my own use. (FWIW, I'm happy to finally contribute something!) Intended features: 1. Doesn't depend on an FFI to libplplot 2. Can automatically place plot area on functions and points 3. Uses parameters for keyword argument default values 4. Uses only dc% primitives / Is very pretty 5. Is more flexible (when using the new plot2d and plot3d modules) Linux screenshots: http://students.cs.byu.edu/~ntoronto/plot2d.png http://students.cs.byu.edu/~ntoronto/plot3d.png The first shows off the almost-finished plot2d. It's as fast as the original `plot', and `shade' is twice as fast. Props to Matthew and Linux's foreign drawing libs for making it look so nice. The second shows off 3d-plot-area%, which wraps a dc% with 3d drawing primitives. The new plot3d will be 1.5x-2x slower, but the new features (e.g. compositing 3d plots, contours) should be worth it. I'll push code to github soon, and ask for volunteers to verify that it looks good on Mac and Windows. Specific questions -- Matthew: It should look good on Mac and Windows if their drawing libs do subpixel-accurate, high-quality antialiasing. Do they? Doug and other heavy `plot' users: What can I add to plot2d and plot3d to make your life easier? Noel: Do you happen to have a kernel density estimator implementation that uses FFT or is otherwise more efficient than O(n^2)? Currently, (plot2d (density samples)) works, but is slow on large samples. Anyone: Are there any original `plot' features that should *not* be emulated in the new `plot' wrapper module? Anyone: Is it easy/possible to manipulate snip%s with, say, a click-and-drag? How about placing edit boxes on them? If it's not hard, I would like to make the 3d plots manipulatable after rendering.

Re: [racket-dev] New plot library [Was: (to Jay) Re: What I'm working on]
I'll write a backward-compatible wrapper for plot, so yes. Mostly. I'll try to emulate it as closely as possible, but any code that depends on the specific pixels or snip% class `plot' generates will probably break. I want plot2d and plot3d to be a little saner than plot. For example, currently, plot2d automatically shows the entirety of a parabolic curve; in contrast, plot only shows it in the area [-5,5] x [-5,5] unless you override it.

If you have something that is close enough it should be fine. Doug Wiliams is probably the heaviest user of plot, so making his code run is probably a good estimate for close enough. There are also some tests in tests/plot that you can look into (they're being compared directly to the png files in there, so they'd obviously break, but should look similar). Two more notes: * IIRC, the only code that was considered as worth keeping is the curve fitting (and some other things around error estimations?) -- it sounds like you have that part done better anyway. * When you look at the current interface, bear in mind that it started with classes, but that was mostly an abuse to get something like keyword arguments.

Doug and other heavy `plot' users: What can I add to plot2d and plot3d to make your life easier? Do you know about ggplot? It's a plotting library based on a grammar of graphic elements, rather than a bucket of pre-set charts, which is what most plotting libraries offer. The design principles behind ggplot are very Scheme-like: a small base of powerful orthogonal features with as few restriction on composition as possible. http://had.co.nz/ggplot2/resources/2007-past-present-future.pdf It would be great to have something like it in ggplot. I do a lot of charting, but I hardly ever use the plot module since the charts I do are more 'information design'-style charts that can't be made with pre-set charts. If DrRacket had a plotting library like ggplot, I would be able to stop building everything by hand from pict's. _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
