[ANN] zcube 0.0.2
Hi, clojure community. It is my pleasure to announce zcube[1], a Clojure library all about counting trees for analytical purposes. The intent is to compute aggregate sums over multiple hierarchical dimensions, based on the (old) algorithmic ideas exposed in [2] by Pr. Minato et Al, and implemented in an immutable setting suitable for concurrent and functional programming. The 0.0.2 version provides a parallel bulk API to compute aggregates over lazy sequences, taking advantage of multicores.

That is the only set of changes that I know of that negatively affect performance in 1.6.0. However, the absolute differences are quite small and codes are cached.

Re: Clojure 1.6.0-RC1 - LAST CHANCE, PLEASE TEST
Hashes are cached for Clojure collections, keywords and symbols, but not for strings. I wonder if people who report these perf regressions use long string keys in their maps... For this to explain the regression they'd have to be looking up the same String objects a lot, of course (else hashCode caching wouldn't have been helpful before the move to Murmur3).

Re: Clojure 1.6.0-RC1 - LAST CHANCE, PLEASE TEST
Hi Alex, the runtime of the program changed from 19 to 20 seconds for one set of data and from approx 6minutes to 6:30 for another set. To me that is acceptable. We are reading a few MB of files into memory, create lots of intermediate vectors, maps and sets and output up to a few hundred MB of data later. All this with pure Clojure, almost no Interop, no protocols, no records or types, just one multimethod which is only used during the first second. Comparison was done by changing the project.clj to point to the desired Clojure version, followed by lein clean lein uberjar and the running the uberjar with a fresh JVM. All this on a QuadCore with 16GB RAM and OpenJDK 1.7 on Linux. We use tools.logging, tools.cli, core.async and log4j and AOT compile :all in the uberjar. If you still consider this a possible breaker (I humbly don't) please let me know, what I should test for you.

Re: More functional Quil
Hello Nikita, I think Quil should definitely provide a way to write functional style processing code. At the moment, my knowledge of both Clojure and Processing is not enough to evaluate these solutions. I'm certainly going to write my code following some of this and if someone proposes a solution to be part of Quil 2, I would happily adopt it and report back on my experiences. BTW, I noticed you had some discussions on IRC, you can find me there as Pupeno. On Monday, March 10, 2014 12:29:00 AM UTC, Nikita Beloglazov wrote: Hi Pablo You can find similar old thread on Quil github repo: https://github.com/quil/quil/pull/19 It may serve as good background what other people considered to make Quil more functional-style. I like your suggestion though I would split your :draw function to 2 fns: an :update function, which only purpose is to update state and :drawwhich draws state and doesn't change the world at all. If this approach is implemented - other handler functions like :mouse-move, :key-pressed are also need to become update-like functions - they should take state as argument and return new state. The only problem is that it is not backward compatible at all. But probably we still can do it... We can add option :fun-mode? true (stands for functional-mode) which enables all these changes - :draw takes state as argument, new :update function is added for modifying state, all handlers behave like :update. This option is enabled per-sketch. It requires additional work on Quil internals, but I think it is doable. This option can be implemented in coming quil 2.0 and it would be great feature to have. One more thing we could do to make it more functional-like - pass changed values to handlers directly. Currently when :key-pressedhandler is called - no argument is passed to the function and you need to use (key-code) or (raw-key) functions to identify which key was pressed. I think this parameters should be explicitly passed to the function. What do you think? Nikita On Sunday, March 9, 2014 1:21:58 PM UTC, J. Pablo Fernández wrote: On Sunday, March 9, 2014 1:02:52 PM UTC, Laurent PETIT wrote: Hello, To be honest I don't see any fundamental difference between your first attempt and the improvement: both share the fact that the mutation of the state happens within the draw function. So in both cases, you have a temporal coupling between updating the state of the app and rendering a new view of the app's state. Yes, what's happening in both cases is very similar, but the function draw in the functional style, in my opinion, is easier to read and maybe it's also easier to test. I would suggest that you don't swap! at all within draw, just deref and render the result of the dereffing. And, in another thread, at potentially a totally different pace than the redrawing's pace, update the application's state accordingly to business rules / constraints. Schematically, something like this: (def app-state (atom (init-state))) (defn draw [...] (let [app-snapshot (deref app-state)] ... call quil primitives to render the application state snapshot ...)) (future ... logic which updates the app-state atom depending on business rules / constraints, in a separate thread ...) I never worked with future, this is exciting, but I have some questions. Do you mean that future is completely separate from draw? I'm just getting started, but draw is not only a function to draw, but as a side effect is the clock of the app, as it's called according to the set frames per second and you normally *take a step* en each draw. Would draw create these futures for the next draw? -- You received this message because you are subscribed to the Google Groups Clojure group.

[ANN] Gorilla REPL 0.2.0 - all new extensible renderer
Hi all, I'm happy to announce a new release of Gorilla REPL. The number one comment I got from people on the original release was that it looked good, but they'd like to see it extended to some library or other. Jeff Rose hit the nail on the head with: Being able to render values of different types is important, and I think it deserves a lot of attention in both the design and documentation. So with that in mind, on to the changes: - All new renderer. This is the main change. The new renderer is simple and predictable, _very_ flexible, supports first-class pluggable custom rendering, and really respects the structure of Clojure values. In particular it renders aggregates of values as you might hope, so you can draw lists of tables, tables of plots, associatives of tables of tables of plots etc. I've made a couple of videos walking through its features, and how easy it is to extend. I'm really pleased with how it's come out :-) https://vimeo.com/89529751 https://vimeo.com/89532785 As per the request, there's also documentation on it. Enough to choke a horse! http://gorilla-repl.org/renderer.html - You can open multiple tabs on the same REPL. This works really nicely - they each get they own session, but share the REPL. - Runs a real nREPL server now, so should work together with things like vim-fireplace that make their own connection to the REPL server. (I haven't tested this though!) - As you might have guessed from the above, there's now a website. http://gorilla-repl.org - Numerous small bug-fixes and feature requests. There are some minor breaking changes, hence the version bump: - Old worksheets will need to be re-run to regenerate their output. - Code that dabbled with the internals of gorilla-plot might need to be adjusted. It's on clojars now, with coordinates [gorilla-repl 0.2.0] . The new renderer lays the foundation for adding rendering for other libraries. I'd love to see support for core.matrix and Incanter, so I think this will be the immediate focus of development. If you maintain a library and would like to see it supported, then please do get in touch. As always, all comments and criticism gratefully received. [Proof-reading this email, I realise I sound rather pleased with myself. My apologies for that, but in truth I think I _am_ rather pleased with how this version has came together!] Yours, Jony -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Clojure 1.6.0-RC1 - LAST CHANCE, PLEASE TEST
Rich just pushed a change to the String hashing to address this. We're going to grab the string hashcode (which is cached after first call) and murmur the result of that. This gives us constant time hashcode after first call with better distribution for combinations in nested collections. Will be in presumed RC2.

[GSoC] Proposal, question and possible call for menthor
Hello, Clojurians! GSoC application deadline is dangerously close and it's time to fill an application, at last. But here is a problem: I don't know what will be the best for community. I have a few ideas and I will present them here to get some feedback. Sorry for a bit late posting! First: this is the idea listed on Ideas Page [1], Data Visualization Components with Om / React.js. I would like to participate; in particular, I'm very interested in building a decent graph rendering library. It seems like there are a lot of JS libraries to draw graphs out there, but all of them lack features that I needed one time or another: -composable layouts/transformations, like in Gephi (you can run one transformation after another there); -static rendering without fancy animation of force-based layout; -efficient handling of data changes (here is where React can be useful); -ability to add user-defined forces. It's very useful when you have special nodes that should be pulled to particular points. Of course, this should be based on top of React's model, which adds an interesting exploratory aspect to the project. Mentor: I've tried to contact Kovas about this project, but wasn't successful. I hope that was a mail quirk. Second: when I write Erlang, I enjoy PropEr (an Erlang property testing library) a lot. Some time ago a similar system was created for Clojure (test.check [2]). It's a decent property-based checker, but a couple of things are still lacking: -support for stateful system checking. This is called statem in PropEr and described in [3]. It's based on modelling stateful system as FSM and comparing behaviour of model and system under test. One of interesting usages of statem in PropEr is to test external servers: for example, properly-designed REST API can be modelled pretty easily by a FSM. -support for automatic generator inference from type specifications (in Clojure Prismatic's Schema can be used) [4]. Obviously, it makes using property-testing a lot easier. -support for generator statistics — what instances was generated, what was the distribution of test sizes and so on. In this project, if it will be selected, I will implement this three features for test.check. I had very positive experience with PropEr and I hope that this project can help more people start using property-based testing. Mentor: Reid Draper. I contacted him and he agreed to mentor the project. Third: arguably, one of the best plotting libraries around is R's ggplot [5]. It was recently ported to Python, as well [6]. It's different from all other libraries of the kind in that it implements a grammar of graphics: small pieces of reusable functionality that together constitute plots. Here is an example: ggplot(mry, aes(x=year, y=number, group=rating)) + geom_line(aes(colour = rating)) + scale_colour_gradient(low=red) # produces [7] This fits Clojure's ideology nicely. It can also be even better in Clojure after a small modification of original ggplot design, which is replacing overloaded plus style with plain vectors. This is a big project, but I believe I can port this library to Clojure and ClojureScript in GSoC timeframe. The majority of code will be the same, and because this will not be a core.X project, I will be able to use cljx to share code. One of spin-offs from this project will be a simple dataframe-like (think R or Python's pandas [8]) data structure usable in both languages. Mentor: there is no at this point. I will appreciate a lot if someone will volunteer. This concludes the list of ideas. Please share your thoughts and let me know, if you are able to mentor me on third project! I will fill an application in 36 hours from now.

Re: STM and persistent data structures performance on mutli-core archs
Due to the path-copy semantics, the contention gets driven to the root of the tree. Out of curiosity, would reference counting (rather than or in addition to normal GC) help with this? Or is reference counting problematic in a highly concurrent environment? It seems like reference cycles will be less of an issue with immutable data. - John -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: STM and persistent data structures performance on mutli-core archs
1. Due to the path-copy semantics, the contention gets driven to the root of the tree. Out of curiosity, would reference counting (rather than or in addition to normal GC) help with this? Or is reference counting problematic in a highly concurrent environment? It seems like reference cycles will be less of an issue with immutable data. Reference counting tends to be less efficient than a tracing collector in a concurrent environment. Reference counts must employ atomic updates that can be relatively expensive, e.g. similar to how AtomicLong.incrementAndGet() works. I've blogged on how atomic increments work. http://mechanical-sympathy.blogspot.co.uk/2011/09/adventures-with-atomiclong.html -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: [ANN] lein-4clj
Admittedly these two libraries are very similar; I actually hadn't heard about lein-fore-prob before (because it wasn't listed on the leiningen plugin list wiki https://github.com/technomancy/leiningen/wiki/plugins). Because I started working on this without knowledge of the other library, it naturally has a few differences; one of which is that it creates separate files while lein-fore-prob puts all the problems into one file (unless multiple projects are created). Also, lein-4clj supports project-less template creation, allowing for a quicker workflow if a 4clojure user wants to quickly try out a solution using the REPL. Anyhow, the two projects are similar and serve essentially the same purpose, so feel free to use whichever you'd like. --Alex --Alex On Wed, Mar 19, 2014 at 4:55 PM, Alan Malloy a...@malloys.org wrote: Can you explain the difference between this and https://github.com/bfontaine/lein-fore-prob?

Re: STM and persistent data structures performance on mutli-core archs
So, the following test puzzles me. Not because it takes virtually the same time (I know that Fork/Join is not cheap and memory is probably the biggest bottleneck here). But because I do not get why map (as opposed to r/ma) uses all 8 cores on my MacBookPro.

honeysql function call limitation
honeysql supports function calls by joining args with commas, e.g.
= (hsql/format #sql/call [:foo :bar :baz])
[foo(bar, baz)]
However sql functions have more syntax, for example group_concat(a order by
b separator ',')
So #sql/call doesn't work. I tried implementing a clause format for
group_concat:
= (hsql/format {:group_concat [:value {:order :ordering :separator
#sql/call [:chr 9]}]})
[GROUP_CONCAT(value order by ordering separator chr(9))]
However this doesn't work inside a select:
= (hsql/format {:select {:group_concat [:value {:order :ordering
:separator #sql/call [:chr 9]}]} :from [:foo]})
[SELECT group_concat AS value AS ( ) FROM foo]
Is there any solution besides dropping to raw sql?
