...uccessfully vmkit I have tried running my java applications, but it failed. I have installed the latest stable release of vmkit (0.29) using the introduction text of the LLVM website. The application does consist of two programs. The first one is a network-based class loader, the other one is a clojure-based Lisp-environment. The network class loader starts slowly with j3, but all is fine at the first moment. After requesting to load some classes and clojure files via an emacs session to the second program, I get following exception trace: Exception in thread "pool-2-thread-1" jav...

However, I managed to crash it once: > j3 -cp clojure-1.1.0.jar clojure.main Stack overflow in VM code or in JNI code. If it is from the VM, it is either from the JIT, the GC or the runtime. This has to be fixed in the VM: VMKit makes sure that the bottom of the stack is always available when entering the VM. Segmentation fault There is no JNI code...

Hi Konrad, I have added some diagnostic message when failing that early in the bootstrap in the VM. Please svn up and let me know what it prints. About the SIGSEGV you get with clojure.jar, I ran the code and got the same error. After investigation, it turns out that the methods you have in that .jar are quite big (50,000 bytecodes) and the static initializer of the core__init class just crashes LLVM because the stack of the thread is not big enough. I hate Java bytecode genera...

...input vector x = runif(n=10e6, min=0, max=1000) x = round(x) #Find one-period difference y = diff(x) Question is: How can I get the 'diff(x)' part as fast as absolutely possible? I queried some colleagues who work with other languages, and they provided equivalent solutions in Python and Clojure that, on their machines, appear to be potentially much faster (I've put the code below in case anyone is interested). However, they mentioned that the overhead in passing the data between languages could kill any improvements. I don't have much experience integrating other languages, so I&...

VMKit runs multiple threads (for example for GC, finalization, etc), so I need the back trace of other threads as well :) Thanks!

Dear R-devel, There is a new feature in R-devel, which explicitly refers to LISP @ operator for splicing. > The backquote function bquote() has a new argument splice to enable splicing a computed list of values into an expression, like ,@ in LISP's backquote. Although the most upvoted SO question asking for exactly LISP's @ functionality in R doesn't seems to be addressed by this

Hi, ' Not specific to 'R'. I search for patterns and found http://patternsinfp.wordpress.com/ which is too heavy for me. There is a 'Pragmatic Programmer' book on such patterns for Scala and Clojure. Is there anything for R ? I wanted to code this. Is there a functional pattern in R for multiple 'if' loops like this ? if( is.na(str_extract(input,"T[^.]*")[1]) ){ }else{ Thanks, Mohan This e-Mail may contain proprietary and confidential information a...

...ery similar to ..(1). In the former case a list of size 1 would be spliced, in the latter case a vector of size 1 is spliced. This would explain why .() and ..() have the same behaviour with scalars. While an interesting thought experiment, this is not how scalars work in R. It seems relevant that Clojure is a lisp that does not allow splicing scalars. Like rlang, Clojure defines the splicing operation in other contexts than pairlists, such as vectors. I suspect the rationale of making scalar-splicing an error in Clojure, even in pairlist context, is to avoid overloading the semantics of this funda...

Much bigger crowd actually :-) - this will work for Scala, Clojure, Jython and all the other cool JVM languages too. (I''ll be doing something similar for .NET, which will bring Cucumber goodness to C#, F# and whatever languages run on .NET. But IronRuby must catch up on speed first). I had the pleasure of going back to visit PicoContainer - a pioneering...

Thanks! I am trying to use it in R. (Actually, I try to give my students experiences with different kinds of files and I was wondering if there were tools available for such kinds of files. I don't know Lisp so I do not actually know what the lines towards the bottom of the file mean.( Many thanks for your response! Best wishes, Ranjan On Wed, 17 Jan 2018 20:59:48 -0800 David Winsemius

I'm in the process of writing a library and giving a talk about writing compilers using LLVM (llvm-c) and Clojure. As part of my talk I'd like to give an example of a program running on CUDA. Are there any papers, tutorials, examples, on writing a custom frontend for NVPTX? For instance, I'm trying to figure out how to get access to "global" variables like blockidx. I know that libc won'...
