Re: [racket-dev] long double for racket
Decimal floating point would be a great addition at some point.

The side effect on that flag is that the FPU gives slightly different (more accurate, but not IEEE-compliant) results for 64-bit operations. That is usually not a problem on machines who have SSE2 (introduced in Pentium 4 in 2001). In presense of SSE2, Racket performs 64-bit operations solely on 64-bit SSE2 registers (see MZ_USE_JIT_SSE and --mfpmath=sse), so the results are IEEE-compliant. 80-bit operations are done on FPU anyway as SSE2 can not do them. Therefore, by setting the extended mode on FPU, we introduce a subtle difference in ordinary flonums, but only on old machines that do not have SSE2. Where is a good place to read more about this? In particular, I'm interested in how IEEE-compliant SSE2 implementations tend to be compared to FPUs. About half the new flonum functions in the math library rely on perfectly compliant rounding for good accuracy in difficult parts of their domains. A few use double-double arithmetic to extend precision from 53-bit significands to 106 in these subdomains; most use a combination of precisions. If rounding isn't IEEE-compliant, these functions could suddenly become much less precise: from just one least significant digit wrong to four or five. That includes computations done *entirely in 80-bit registers*, which seems like it should be more accurate. For example, there's a heavily used macro that computes the result of `fl+' and its rounding error. If it were done entirely in 80 bits and then rounded to 64, the error computation would be totally bogus. I'd like to verify independently that this won't happen on machines with an Intel FPU manufactured within the last 12 years or an AMD FPU manufactured within the last 10 (i.e. those with SSE2). That would keep me happy, since FPUs older than those tended to rounding incorrectly anyway. Thanks!

I'm also probably going to go to some trouble to avoid using new 5.3 features in some code that might be deployed to production in the very near term. More information might be reassuring to me.

[racket-dev] Best way to handle duplicate identifiers
Racket now includes nan? and infinite? in the core language, which were already defined and provided by the science collection in PLaneT. This isn't a problem, per se, with the code itself, but the documentation doesn't build in the pre-release because of the duplicate labels. In a perfect world, I'd just remove all traces of them from the science collection and documentation, but then (some) programs that use the science collection would fail for older versions. What is the best way to handle this? Should I remove them from the science collection and change the dependency for the new version to the latest Racket version? Can I easily do that for a pre-release version? [For example I noticed that the pre-release version I downloaded on the 20th was 5.2.901.1 and the one I downloaded today was 5.2.900.1 - at least in the filenames. So the numbers seem (to me) to have gone backwards.] Also, should I consider the new release to not be backwards compatible? [I don't think there would be any breakage of code using it, but there might be some edge cases I'm not aware of.] Should I leave them in the science collection and just change the documentation to exclude nan? and infinite? on the requires? This is what I had done previously when they popped up in the plot/utils module. Should the science collection just export the new nan? and infinite? routines so they are still provided? [That might handle any edge cases I'm not aware of.] I suspect that I will be having more of these as Neil's new math routines are released. So, I should probably figure out the best approach that doesn't break anything. Doug _ Racket Developers list: http://lists.racket-lang.org/dev

Re: [racket-dev] Pre-Release Checklist for v5.3
And one last post on this. Now it is reliably running. I'm assuming once I got a .zo of the offending module actually built, from then on I'm okay as long as I don't play around with it. Does that make sense? And, just to test that, I deleted the compiled directory and the weird behavior comes back. I (re-)load it and hit run enough times until I get it to start and from then on it starts fine.

Re: [racket-dev] New plot library pushed
None of the contracts for any of the plot routines were a problem. I was talking about contracts on my own functions. For example, if I have a function f(x) with a (/c 0.0) contract, I still have to use #:x-min 0.001 (or something like it) instead of #:x-min 0.0 to avoid the contract error. But, I would say that is the expected behavior. Yes, the porting page was helpful. And really, the port was not hard at all. The only thing that required much thought was getting the rectangles to work for histograms. I incorrectly homed in on the word histogram. It might be nice to provide a plain histogram renderer. But, it really wasn't hard after I found rectangles. And thanks for writing the discrete-histogram, that was very useful.

Neil's seems to be much more robust and forgiving. I'll take credit for half of that.

(E.g. polygons with at least one hole don't get drawn, lines get split.)

[racket-dev] Transparent Structures in XML Library
Maybe this is general question or observation, but I specifically have the problem with the xml module in Racket. All of the structures defined in collects/xml/private/structures.rkt are transparent. Most of my xml files are hundreds of thousands of bytes to tens of megabytes in size. Needless to say, if any of these make it to a display statement, it isn't pretty. Actually, since the structures also include location information, the result can be (is) larger than the actual XML was. I don't think they are transparent for any reason other than some east of debugging - and for large xml structures it is actually (in my opinion) detrimental to debugging. And, it doesn't help by adding an equality test because of the location information - equal? is pretty much identical to (an extremely slow) eq? in this case. Could we get rid of the #:transparent option on those structures? Or, if they are really there for a reason, at least add a prop:custom-write that limits the potential output from printing an instance? This is the only case where I have run into the 'problem'. But, there may be other places it exists. I am also guilty of using transparent structures sometimes, so I can't be too critical here.

The fact that transparent structures also print all of their element - in this case recursively, ad nauseam - is more of a side effect.

Re: [racket-dev] Transparent Structures in XML Library
Basically, I'm just suggesting that the xml package have sensible printing of its structures. I can't imagine any case where you really want the default printing of recursive structures of that complexity and potential size to be the visible behavior. Where it was annoying me was in my inference engine when I was doing inference across very large xml documents. I have a trace feature in the inference engine to trace assertions that is very useful for debugging rules. You can imagine the output when I turned it on the first time with one of the large xml documents. Literally, one assertion was 100+ pages. I've pushed a new version of the inference engine that uses ~.s throughout. So, at least it prints it reasonable.

Re: [racket-dev] Adding the new plot library [was: Re: Plot?]
Neil, I haven't had a chance to read the thread thoroughly - hopefully I can this evening at home. But, I'd like to update the science collection graphics to use it. Fortunately, all of the graphics routines are in separate modules, so it shouldn't be too bad. I do use the plot extensions to add new capabilities to the current plot package - for example, for 1d and 2d histograms. Is the plot extension capability still there? [It wouldn't be that hard to write the histograms from scratch if it isn't.] Also, in my analysis code at work we do use the contour plots for some things. Pretty much everything else is in my own specialized plot packages.

So I guess I don't understand. Why would we want to keep that? (I can see why we would want to get rid of it.) Because you wanted to have a completely compatible interface? (Excluding pixels.) My point was that if you don't keep it (which I very strongly prefer), then you don't have a compatible interface to plot anyway, and changing the name from `plot' to `plot/compat' makes more sense. The pixels that make up the plots generated by the compatibility library are quite different. But I can't imagine that nicer plots will be anything but a pleasant surprise. So I don't want to read about pixels anymore. Seriously. Logical reductio ad absurdum about pixels in pictures - which are valuable because of their *semantic* content - borders on fallacious. It won't get us anywhere. What will is discussing the most important user interactions. -- The first is what happens when users run old code that uses the 'plot' library. - (Robby/Sam) The compatibility library is 'collects/plot' and the new library is 'collects/rackplot' (or 'collects/omg-raph' or whatever): their code just runs. - (Eli) The compatibility library is 'collects/plot/compat' and the new library is 'collects/plot': some code will run with more changes than just pixels (semantic errors in the plots), some will give runtime errors, and most will give compile-time errors. Examples: (plot (points (list (vector a b) ...))) = Runs, but puts tighter bounds on the plot (semantic error) (plot (error-bars (list (vector a b c) ...))) = Runs, but puts tighter bounds on the plot (semantic error) (plot (points (list (vector a b) ...) #:sym 'fullsquare)) = points: does not expect an argument with keyword #:sym (plot (vector-field (λ (v) v))) = vector-field: contract violation, expected a procedure that accepts 2 mandatory arguments without any keywords, given: #procedure contract from: (function vector-field), blaming: collects/plot/plot2d/point.**rkt (plot (line sqr)) = expand: unbound identifier in module in: line Also, 'contour', 'shade' and 'surface' do the same as 'line'. Observations: There's nothing that tells the user that changing (require plot) to (require plot/compat) will fix the errors. It just looks like random fail. But if it's random fail only once for a very small percentage of users, it might be okay-ish. -- The second interaction is what happens when new users look for plot in the manual. - (Robby/Sam): They get the old 'plot'. Clicking on it reveals a big red deprecation warning, and a link to the new stuff. Of course, that doesn't guarantee that they will *read* the warning. - (Eli): They get the new 'plot', with a note about the compatibility library that they can ignore. Observations: With Robby/Sam's idea, the apparent bait-and-switch, and needing two clicks to get to the right library, is also fail. And it lasts for years until we finally decide to rip out the compatibility library, and thus break more code. -- To me, the ideal would be to name the compatibility library 'collects/plot', and then somehow keep it from showing up in searches.

[racket-dev] Cross-Collection Documentation - a PLaneT Philosophy Question (or Two)
I have three PLaneT packages that together implement a knowledge-based simulation capability. I did this because each of the packages is useful in its own right. The science collection provides the basic mathematical framework - I use it separately in many analysis applications. The simulation collection provides a hybrid discrete-event and continuous simulation engine. The inference collection provides a hybrid forward-chaining and backward-chaining inference engine. Although they were developed together and I often use them together, they are separate collections. As such, they are documented separately and the examples in each are specific to that collection. Now, I have written a good example knowledge-based simulation that cuts across all of them and I am planning on developing documentation on how to use the packages together. Should I package this up as a PLaneT package itself although it doesn't add any new functionality? Is there a better way to distribute something like this - more like an application note than an applicaton? It seems to be the only way to do it in the current framework. [It will be in the Schematics repository on Sourceforge. But I pretty much just use that as my development repository.] Also, when using the simulation collection one (almost) always uses the random distributions from the science collection. In my development branch, I have now just re-exported the random distributions in the science collection from the simulation collection. Thus, I only have the one PLaneT require in user code instead of two. [I don't want to move the random distributions to the simulation collection because they really are part of the mathematical framework and logically belong in the science collection.] Is this going to bite me later if someone needs other elements of the science collection and does a separate require - i.e., will the names conflict even though they are (ultimately) the same objects?

[racket-dev] Can't use 5.1.2 and later
I reported a problem a few weeks back that keeps me from using 5.1.2 (and now 5.1.3). Matthew believes it is due to an optimizer bug with boxes. Fortunately, 5.1.1 works, but we're stuck there. I tried the latest nightly build this morning and the error is still there. [That was mainly just a friendly nudge to Matthew.] Anyway, the real reason for this e-mail is that the latest nightly build (which was plt-3.1.3.6-bin-x86_64-win32.exe) gave me another problem. When I downloaded the science collection from PLaneT using the latest nightly build, it gave me errors about expecting a module for some files. There are indeed some rkt files that are included - using include - that are not modules. But, they are in the compile-omit-files in the info.rkt file. Is this being deprecated in some way?

Re: [racket-dev] Can't use 5.1.2 and later
You might try running science-test.rkt multiple times and see if it fails. It's the simulation collection where I see the problem mostly. It uses the differential equation solver from the science collection, which is the only place I know of that uses boxes, but there may be others. I was using Windows 7 64-bit today when I tried it. I'll see if science-test works for me. When it does fail for me now, it is consistently with a seg fault in gc. I'll keep checking nightly builds on my home machine in the evenings.

[racket-dev] Problem with latest nightly build
I downloaded the latest nightly build to test a fix that Matthew pushed. That fix (a refresh problem) worked, but when I tried to run some numerically intensive things - like the test for the science collection - I ran into problems. The science test hangs on the last differential equation test - eventually it runs out of memory. Some other examples seg fault in the garbage collector. I tried both 32 and 64 bit windows versions and they both had the same symptoms. These all work fine in 5.1.2. I tried a nightly build from yesterday (5.1.2.4) and one from this morning (5.1.3.1) and they both had the problem. Sorry I can't be more specific. You can require the science collection from PLaneT - williams/science/science - and run science.test.ss. That one fails every time for me by running out of memory eventually - I typically have memory limited to 4096MB on a 64-bit build or 2048 on a 32-bit build. I also tried some of the simulation examples that use the same differential equation solver - they're in williams/simulation/simulation. For example, model-2a.ss will sometime run fine and sometimes fail with a seg fault. Another one that fails sometimes and runs others is interactions.ss in the simulation collection. Let me know if I can get you any other information on the problem. Doug _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
[racket-dev] Different refresh behavior between 4.2.5 and 5.0+
I would like to migrate my production machines from the current PLT Scheme 4.2.5 to the latest release of Racket.However, there is one annoying graphics inconsistency with graphics refresh that is giving me problems. For some of my graphics programs, I update many canvases - some visible and some not, depending on what tabs are selected - and afterwards I just issue one (send the-frame refresh). This works fine in 4.2.5. However, in 5.0+ (at least the last couple versions), some of the canvases update and some don't. One can switch to a different tab and back to force the repaint and that works, but obviously annoys the users. I haven't experimented enough to track down exactly which do and which don't. [I rolled my production machines back to 4.2.5 and haven't moved that code to a development machine to play with it.] There seem to be a couple of open bugs reports that may or may not be related - 11759 and 12065. On my development code that has a similar problem I moved the refreshes down to the individual canvases (as they are updated) and that works. But it seems that one refresh of the frame at the end should work just a well. Is this a new feature that I missed somewhere or a bug?

Re: [racket-dev] (round), etc. in Typed Racket
Since Racket is not Scheme anymore, I think revisiting some of the annoyances of Scheme should be fair game. And, certainly the semantics of integer? is an annoyance. It is useful if you KNOW you are restricted to a range where floating point CAN exactly represent an integer (|x| 15 or so) and you KNOW you don't have any rounding errors, otherwise it isn't. For example: (integer? (+ 1.0e15 0.5)) #f (integer? (+ 1.0e16 0.5)) #t For Typed Racket, I'm not sure there could ever by a safe use of an integer type with those semantics. The semantics of integer? is just a (very limited) subset of what fcmp ( http://fcmp.sourceforge.net/) does. From the web page, It is generally not wise to compare two floating-point values for exact equality, for example using the C == operator. The fcmp package implements Knuth's suggestions for safer floating-point comparison operators as a C function. As an aside, fcmp is in the science collection.

Well, the change to TR would be to change Integer to ExactInteger (or similar) presumably, not to add a useless type. I think not having an `Integer' type would be just as bad. Given that (integer? 3.0) = #t, I think there will be an inevitable discrepancy between what people expect and what the type system does. One of these definitions has to not type check: (: x : Integer) (define x 1) (: f : Integer - Integer) (define (f x) (add1 x)) (: g : Any - Integer) (define (g x) (assert x integer?)) You're suggesting the first one fail, because `Integer' would go away. Right now only `g' fails. Adding an `Integer' type that corresponds to `integer?' would make `f' fail. My feeling is that the fewest people will run into `g', and that it's therefore the right choice, since there will be a FAQ about this regardless. Well, IMO, given that the main driving design force behind TR is matching up with Racket that you should not pick a simple convention for relating Racket predicates to Typed Racket types and stick with it (unless you can change Racket and, in this case, changing Racket seems too hard). When you make exceptions to this rule, you'd want to do that carefully and have big warnings in the docs, etc. Another possible compromise point would be to have two types, Integer and ExactInteger where Integer is a kind of alias for ExactInteger that the type system itself never prints out, but that it accepts as input. And perhaps you could even have a #:warn directive (like the optimization flag) that would print out messages complaining about using such aliases or something. Or would it be possible to have a type Integer that actually matched what integer? does? That would have the problem that people might expect optimizations to kick when they wouldn't, but perhaps that's the least painful point (well, I guess adding more complication to the number hierarchy type system is its own source of pain ...)

Re: [racket-dev] try the GRacket2 branch
I got GRacket2 running under Ubuntu. In general, things work as expected. It is my animations that I'm most concerned about and some work and some don't. I've only tried the ones that are available on PLaneT - I haven't even checked any of the others yet. The animated-canvas library that I have on PLaneT has two examples. The histogram-test.rkt example works as expected. The lines.rkt example draws a few lines and then locks up. Adding a (yield) after (send canvas swap-bitmaps) in line 55 gets it to run - sort of. The animation is fairly smooth for 10 sets of lines, but is really strange at 50 (for example) - with this machine on the old GRacket it would be smooth at 100. And, my stop button implementation doesn't work will - it just sets a global and the graphics routines exit when they see it set - it eventually stops, but may require 10 to 15 seconds or so. I suspect that the animated-canvas functionality for double-buffering may not be needed anymore and the 'flush' operations are what I need to look at. The interactions.ss file in the simulation package on PLaneT also required a (yield) after line 107 to give the animation effect - there is no double buffering or anything here. But, with that added, it seems to run fine. I guess I need a better understanding of how the new canvas is working in order to deprecate the animated-canvas capability for my animations.

[racket-dev] Scribble Racket Code with Here Strings
I sometimes use here strings for readability when building queries, etc.
For example:
(let-values (((variables results)
(get-repository-query-tuple r
#---
select * from {x} sys:repositoryID {y}
using namespace
sys = http://www.openrdf.org/config/repository#
---

(printf Repository ids = ~s~n
(for/list ((bindings (in-list results)))
(binding-string (bindings-ref bindings 'y)
But I haven't found a good way to document this (as Racket code) in
Scribble. Everything I've tried renders like:
(let-values (((variables results)(
get-repository-query-tuple r select * from {x}
sys:repositoryID {y}\r\nusing namespace\r\n sys =
http://www.openrdf.org/config/repository#\r
#:query-language 'SERQL)))(printf Repository ids = ~s~n(
for/list ((bindings (in-list results))) (binding-string (
bindings-ref bindings 'y)
That is, the here string has been rendered as a normal string with lots of
whitespace after.
Any ideas?

[racket-dev] Equality test for Not-A-Number
What is the correct way to test for +nan.0 in Racket? For example, (= +nan.0 +nan.0) = #f. This seems to be the behavior specified in R6RS. In the science collection I implemented nan? using eqv?, which seems to work in Racket; but the result is explicitly unspecified in R6RS, which I assume means that it's up to the implementation. Which pretty much leaves eq? as the proper test. R6RS includes primitives like nan? and infinite?, which I included a long time ago in the science collection.

But, in the random distribution functions it is the first argument that is optional and that won't work. So, for example the flat (i.e., uniform) distribution includes a contract: (case- (-r ((r random-source?) (a real?) (b (/c a))) real?) (-r ((a real?) (b (/c a))) real?)))

But, I am getting different numeric answers for some of my science collection routines (for example, the gamma function) and some of my newer code (for example, FFT) either fails with an error message or DrRacket just dies.

If you have any bug-fixes and changes that need to go in the release then make sure to specify that in the commit message or mail me the commit SHA1s. You can `git checkout release' to try it out directly if needed -- but do not try to push commits on it (the server will forbid it). Note that nightly builds will go on as usual (as v5.0.2.1), and pre-release builds will be available shortly at http://pre.racket-lang.org/release/ Please tell me if you think that this should be announced on the users list for wider testing. -- Ryan Culpepper _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
Re: [racket-dev] expected timing difference between fft-complex-forward and fft-complex-radix2-forward?
On my laptop: #lang racket (require fft.rkt) (define v (build-vector 16384 (lambda (i) (random (define v1 (vector-copy v)) (collect-garbage) (collect-garbage) (collect-garbage) (time (fft-complex-radix2-forward v1)) (define v2 (vector-copy v)) (collect-garbage) (collect-garbage) (collect-garbage) (time (fft-complex-forward v2)) (for/and ([i (in-range (vector-length v))]) ( (magnitude (- (vector-ref v1 i) (vector-ref v2 i))) 1e-4)) == cpu time: 94 real time: 94 gc time: 0 cpu time: 79 real time: 78 gc time: 0 #t I'll look at the rsound/fft implementation and see if I see the problem.

But, when I looked, the longer time was almost exclusively GC - it just happen to hit that particular call. When I put a (collect-garbage) before each call, they were all 50ms on my machine. So, the GC penalty is likely what you're seeing. The other thing is to make sure you aren't calling one of the dft routines instead of the fft routines. Those are the only ones that get anywhere near 24s on my machine - they are about 20s on my machine. The dft routines are the 'straight' mathematical discrete Fourier transform and do not use the FFT algorithms at all. [They're really only useful for a sanity check on results.] Right, got it. No, the times I'm seeing are not GC. I bumped it up to an 8192-point fft, and now the radix-2 version is about 400x faster. Here's my code: #lang racket (require (planet clements/rsound/fft)) (define v (build-vector 16384 (lambda (i) (random (define v1 (vector-copy v)) (collect-garbage) (collect-garbage) (collect-garbage) (time (fft-complex-radix2-forward v1)) (define v2 (vector-copy v)) (collect-garbage) (collect-garbage) (collect-garbage) (time (fft-complex-forward v2)) (for/and ([i (in-range (vector-length v))]) ( (magnitude (- (vector-ref v1 i) (vector-ref v2 i))) 1e-4)) = cpu time: 208 real time: 211 gc time: 0 cpu time: 81357 real time: 82502 gc time: 8337 #t John Clements On Thu, Oct 14, 2010 at 4:34 PM, John Clements cleme...@brinckerhoff.org wrote: On a vector of length 8192 (a power of 2, natch), fft-complex-radix2-forward takes about 1/8 of a second (lost in the noise, essentially), but fft-complex-forward takes more than 24 seconds, a difference of about 200x. They do produce the same answers, up to differences of 1e-4 in the magnitude (didn't check the phase). 1) Is this expected? I thought the non-radix2 one was still fairly clever about subdividing when the number of points is divisible by 2. 2) If so, would it make sense to test for powers of 2?

Re: [racket-dev] Can't Find a Workaround for Bug 11017 in DrRacket
With last night's build, the error message is now: cm: no SHA-1 for dependency: #C:\\Documents and Settings\\williamsm\\My Documents\\Development\\madness\\madness.rkt I am using a development link (using PLaneT) to reference the madness (which is an acronym for Multi-Agent Dynamic Network Simulation System - MADNeSS, not a reference to my mental state) development folder. But, the files in it are actually .ss files - as are all of the files involved. So, I'm guessing that somewhere along the line the development link to (planet williams/madness/madness) didn't 'remember' it was to a .ss file instead of a .rkt file.
