  • Calculate the digital root of a number

    - by Gregory Higley
    A digital root, according to Wikipedia, is "the number obtained by adding all the digits, then adding the digits of that number, and then continuing until a single-digit number is reached." For instance, the digital root of 99 is 9, because 9 + 9 = 18 and 1 + 8 = 9. My Haskell solution -- and I'm no expert -- is as follows. digitalRoot n | n < 10 = n | otherwise = digitalRoot . sum . map (\c -> read [c]) . show $ n As a language junky, I'm interested in seeing solutions in as many languages as possible, both to learn about those languages and possibly to learn new ways of using languages I already know. (And I know at least a bit of quite a few.) I'm particularly interested in the tightest, most elegant solutions in Haskell and REBOL, my two principal "hobby" languages, but any ol' language will do. (I pay the bills with unrelated projects in Objective C and C#.) Here's my (verbose) REBOL solution: digital-root: func [n [integer!] /local added expanded] [ either n < 10 [ n ][ expanded: copy [] foreach c to-string n [ append expanded to-integer to-string c ] added: 0 foreach e expanded [ added: added + e ] digital-root added ] ] EDIT: As some have pointed out either directly or indirectly, there's a quick one-line expression that can calculate this. You can find it in several of the answers below and in the linked Wikipedia page. (I've awarded Varun the answer, as the first to point it out.) Wish I'd known about that before, but we can still bend our brains with this question by avoiding solutions that involve that expression, if you're so inclined. If not, Crackoverflow has no shortage of questions to answer. :)

  • Best (functional?) programming language to learn coming from Mathematica

    - by Will Robertson
    As a mechanical engineering PhD student, I haven't had a great pedigree in programming as part of my “day job”. I started out in Matlab (having written some Hypercard and Applescript back in the day, and being introduced to Ada, of all things, in my 1st undergrad year), learned to program—if you can call it that—in (La)TeX; and finally discovered and fell for Mathematica. Now I'm interested in learning a "real" programming language that I can enjoy in the same sort of style as Mathematica, which tries to stress functional programming since it seems to map more nicely to how certain kinds of mathematics can be written algorithmically. So which functional language should I learn? I guess the obvious answer is “as many as possible”, but let's start out humble and give a single, well-considered option a good crack. I've heard good things about, say, Haskell and Scala, but I wonder if (given my non–computer science background) I'd be better off starting in more “grounded” territory and going with Ruby or Python (the latter having the big advantage of being used for Sage, which I'd also like to investigate…after my PhD). Well, I guess this is pretty subjective, so perhaps I could rephrase: would it be better to start looking at Haskell (say) straight after an ad-hoc education to functional programming in Mathematica, or will I get more out of learning Python (say) first? In reference to the question "what do I want to do with it?", I guess my answer is "fun, and learning more". I've got this list of languages that I'd like to look at, and I don't know how to trim them down. And I'd rather start with something a little higher-level than C simply so that I can be somewhat productive without having to re-invent many wheels for any code I'd like to write.

  • How can I configure GIMP 2.8 to be a single window in XMonad?

    - by Pubby
    I'm trying to get GIMP to display as a single window in XMonad. Currently, it's floating strangely in front of every other display and I can't use it. I have tried reading this: http://www.haskell.org/haskellwiki/Xmonad/General_xmonad.hs_config_tips#Gimp But it seems this is for versions of GIMP before 2.8 when there wasn't the option to have GIMP use only 1 window. Because of this, it's an XMonad problem, not a GIMP one. How can I do this?

  • How to set CPU affinity in Wine or CrossOver?

    - by penyuan
    There are some old games who don't like the multicore processors in today's computers. I am wondering if there is a way to set the CPU affinity for them to '1' under Wine or CrossOver? i.e. In a native Windows environment you would right click on the game's process in the Task Manager then set the affinity there. I've came across a program called RunFirst.exe, but can't figure out a way to run it, then the game in one command. Suggestions are appreciated. Thanks!

  • CPU Affinity on ARM processors

    - by dsljanus
    I am using some RaspberryPI boards for a data acquisition system. They are nice boards, with plenty of community support around them, but they are really slow. I am thinking of gradually replacing them with ODROID multicore boards, with the Samsung Exynos processors. I have some experience using taskset to set CPU affinity on my servers because I am always running Node.js applications that are by definition single threaded. Now, is it possible to do this on an ARM board? I do not see why it would not in theory, but I have doubts over how well it is going to work. Does anyone have experience with this kind of hack? Also, I would appreciate any comments about ARM CPUs and how they differ from x86.

  • SQL server availability issue: large query stops other connections from connecting

    - by Carlos
    I've got a high-spec (multicore, RAID) server running MS SQL 2008, with several databases on it. I have a low throughput process that periodically needs a small amount of information from one of the DBs, and the code seems to work fine. However, sometimes when one of my colleagues does a huge query against one of the other DBs, I see full CPU usage on the machine, and connections from my app time out. Why does this happen? I would have thought the many cores and harddisks would somehow (together with cleverly written DB server) be able to keep at least some of the resources free for other apps? I'm pretty sure he doesn't use multiple connections for his query. What can I do to prevent this?

  • Configuring MPI on 2 nodes

    - by Wysek
    I'm trying to create really simple "cluster" from 2 multicore computers using openmpi. My problem is that I can't find any tutorials on that matter. I don't want to use torque because it's not necessary in my case nevertheless all tutorials give configuration details either about torque or mpd (which doesn't exist in openmpi implementation). Could you give me some tips or links to appropriate manuals? Steps I've already completed: - openmpi installation - network configuration (computers see each other) - ssh password-less login to second computer I tried using machinefiles without further configuration and with just 2 IPs in it. But jobs don't seem to start at all after initialization part. (MPI seems to work because I'm able to scatter jobs on multiple cores of both computers without communication between them).

  • C++/msvc6 application crashes due to heap corruption, any hints?

    - by David Alfonso
    Hello all, let me say first that I'm writing this question after months of trying to find out the root of a crash happening in our application. I'll try to detail as much as possible what I've already found out about it. About the application It runs on Windows XP Professional SP2. It's built with Microsoft Visual C++ 6.0 with Service Pack 6. It's MFC based. It uses several external dlls (e.g. Xerces, ZLib or ACE). It has high performance requirements. It does a lot of network and hard disk I/O, but it's also cpu intensive. It has an exception handling mechanism which generates a minidump when an unhandled exception occurs. Facts about the crash It only happens on multiprocessor/multicore machines and under heavy loads of work. It happens at random (neither we nor our client have found a pattern yet). We cannot reproduce the crash on our testing lab. It only happens on some production systems (but always in multicore machines) It always ends up crashing at the same point, although the complete stack is not always the same. Let me add the stack of the crashing thread (obtained using WinDbg, sorry we don't have symbols) ChildEBP RetAddr Args to Child WARNING: Stack unwind information not available. Following frames may be wrong. 030af6c8 7c9206eb 77bfc3c9 01a80000 00224bc3 MyApplication+0x2a85b9 030af960 7c91e9c0 7c92901b 00000ab4 00000000 ntdll!RtlAllocateHeap+0xeac (FPO: [Non-Fpo]) 030af98c 7c9205c8 00000001 00000000 00000000 ntdll!ZwWaitForSingleObject+0xc (FPO: [3,0,0]) 030af9c0 7c920551 01a80898 7c92056d 313adfb0 ntdll!RtlpFreeToHeapLookaside+0x22 (FPO: [2,0,4]) 030afa8c 4ba3ae96 000307da 00130005 00040012 ntdll!RtlFreeHeap+0x1e9 (FPO: [Non-Fpo]) 030afacc 77bfc2e3 0214e384 3087c8d8 02151030 0x4ba3ae96 030afb00 7c91e306 7c80bfc1 00000948 00000001 msvcrt!free+0xc8 (FPO: [Non-Fpo]) 030afb20 0042965b 030afcc0 0214d780 02151218 ntdll!ZwReleaseSemaphore+0xc (FPO: [3,0,0]) 030afb7c 7c9206eb 02e6c471 02ea0000 00000008 MyApplication+0x2965b 030afe60 7c9205c8 02151248 030aff38 7c920551 ntdll!RtlAllocateHeap+0xeac (FPO: [Non-Fpo]) 030afe74 7c92056d 0210bfb8 02151250 02151250 ntdll!RtlpFreeToHeapLookaside+0x22 (FPO: [2,0,4]) 030aff38 77bfc2de 01a80000 00000000 77bfc2e3 ntdll!RtlFreeHeap+0x647 (FPO: [Non-Fpo]) 7c92056d c5ffffff ce7c94be ff7c94be 00ffffff msvcrt!free+0xc3 (FPO: [Non-Fpo]) 7c920575 ff7c94be 00ffffff 12000000 907c94be 0xc5ffffff 7c920579 00ffffff 12000000 907c94be 90909090 0xff7c94be *** WARNING: Unable to verify checksum for xerces-c_2_7.dll *** ERROR: Symbol file could not be found.

What I have tried so far Reviewing all the code related to the point where the crash ends happening. Trying to enable pageheap on our testing lab though nothing useful has been found by now. We have substituted the std::list for a C array and then it crashes in other part of the code (although it is related code, it's not in the code where the old list resided). Coincidentally, now it crashes in another erase, though this time of a std::multiset. Let me copy the stack contained in the dump: ntdll.dll!_RtlpCoalesceFreeBlocks@16() + 0x124e bytes ntdll.dll!_RtlFreeHeap@12() + 0x91f bytes msvcrt.dll!_free() + 0xc3 bytes MyApplication.exe!006a4fda() [Frames below may be incorrect and/or missing, no symbols loaded for MyApplication.exe] MyApplication.exe!0069f305() ntdll.dll!_NtFreeVirtualMemory@16() + 0xc bytes ntdll.dll!_RtlpSecMemFreeVirtualMemory@16() + 0x1b bytes ntdll.dll!_ZwWaitForSingleObject@12() + 0xc bytes ntdll.dll!_RtlpFreeToHeapLookaside@8() + 0x26 bytes ntdll.dll!_RtlFreeHeap@12() + 0x114 bytes msvcrt.dll!_free() + 0xc3 bytes c5ffffff() Possible solutions (that I'm aware of) which cannot be applied "Migrate the application to a newer compiler": We are working on this but It's not a solution at the moment. "Enable pageheap (normal or full)": We can't enable pageheap on production machines as this affects performance heavily. I think that's all I remember now, if I have forgotten something I'll add it asap. If you can give me some hint or propose some possible solution, don't hesitate to answer! Thank you in advance for your time and advice.

  • What are the reasons why Clojure is hyped and PicoLisp widely ignored?

    - by Thorsten
    I recently discovered the Lisp family of programming languages, and it's definitely one of the more diverse and widespread families in the programming language world. I like Elisp because that most wonderful tool Emacs is an Elisp interpreter. But I was looking for one more Lisp dialect to learn and thought Clojure would be the obvious choice nowadays - until I discovered the well hidden gem PicoLisp. That must be the most intelligent programming environment I have ever seen, like taking the best ideas from Lisp and Smalltalk and adding performance and practicability - and the beauty of parsimony. There is even an Emacs-mode for it. PicoLisp must be the productivity world champion when it comes to building business applications with database and web-client - and that's a very common task. It seems that throwing more and more hardware cores at your PicoLisp application makes it faster and faster, and the database is very performant anyway. However, reactions to PicoLisp in in general mailing-lists etc. are almost hostile (envy?), and there is absolutely no hype and very little publicity (ie not one book published). Are there real justified reasons for this (except the vast amount of java-libs accessible by Clojure, I know that one)? Or is the mainstream it getting wrong again (see C vs Lisp, Java vs Smalltalk, Windows vs Linux) and will come to the conclusion 10 years later that the JVM was good as in between solution, but a really fast Lisp interpreter on multicore machines is much better and allows much cleaner concepts? PS 1: Please note: I'm not interested in Scheme or any Common Lisp dialect, although they might be fine languages. It's just PicoLisp vs Clojure. PS 2: another thing I like about PicoLisp is its similarity to Elisp in certain aspects (both are descendants from MacLisp?) - it's easier to learn two similar languages. There is so much "dynamic binding bashing" on the web, but two of the most appealing Lisp applications use it.

  • What Functional features are worth a little OOP confusion for the benefits they bring?

    - by bonomo
    After learning functional programming in Haskell and F#, the OOP paradigm seems ass-backwards with classes, interfaces, objects. Which aspects of FP can I bring to work that my co-workers can understand? Are any FP styles worth talking to my boss about retraining my team so that we can use them? Possible aspects of FP: Immutability Partial Application and Currying First Class Functions (function pointers / Functional Objects / Strategy Pattern) Lazy Evaluation (and Monads) Pure Functions (no side effects) Expressions (vs. Statements - each line of code produces a value instead of, or in addition to causing side effects) Recursion Pattern Matching Is it a free-for-all where we can do whatever the programming language supports to the limit that language supports it? Or is there a better guideline?

  • To maximize chances of functional programming employment

    - by Rob Agar
    Given that the future of programming is functional, at some point in the nearish future I want to be paid to code in a functional language, preferably Haskell. Assuming I have a firm grasp of the language, plus all the basic programmer attributes (good communication skills/sense of humour/hygiene etc), what should I concentrate on learning to maximize my chances? Are there any particularly sought after libraries I should know? Alternatively, would another language be a better bet, say F#? (I'm not too fussed about the kind of programming work, so long as it's reasonably interesting and reasonably well paid, and with nice people)

  • Selling your services when you use uncommon technologies

    - by speeder
    I took a look in Stackoverflow most popular profiles, and then I did the same in several other sites, and then I took a look in job postings in several boards, mostly out of curiosity, because I noticed this: If you work with Java, .NET or other managed languages, or you work with stuff that is popular for web development (Ruby, JavaScript, etc...) you can get lots of points on Stackoverflow, find lots of jobs and clients, find forums, friends, colleagues, etc... But how a programmer of uncommon languages (Lua, pure C, Lisp, D, ADA, Haskell, etc...) find information, sell his services, and so on? EDIT: This also applies to fields: You work with web, corporate software, database, etc... it is great... You dislike those previous 3, noone ever will hire your services...

  • Outdoor Programming Jobs...

    - by Rodrick Chapman
    Are there any kinds of jobs that require programming (or at least competency) but take place outdoors for a significant portion of the time? As long as I'm fantasizing, an ideal job would involve programming in a high level language like Haskell, F#, or Scala* for, say, 50% of the time and doing something like digging an irrigation trench the rest of the time. My background: I triple majored in mathematics, philosophy, and history (BS/BA) and have been working as a web developer for the past six years. I love hacking but I'm feeling a bit burned out. *I only chose these languages as examples since, ideally, I'd want to work among high caliber people... but it really doesn't matter.

  • What's special about currying or partial application?

    - by Vigneshwaran
    I've been reading articles on Functional programming everyday and been trying to apply some practices as much as possible. But I don't understand what is unique in currying or partial application. Take this Groovy code as an example: def mul = { a, b -> a * b } def tripler1 = mul.curry(3) def tripler2 = { mul(3, it) } I do not understand what is the difference between tripler1 and tripler2. Aren't they both the same? The 'currying' is supported in pure or partial functional languages like Groovy, Scala, Haskell etc. But I can do the same thing (left-curry, right-curry, n-curry or partial application) by simply creating another named or anonymous function or closure that will forward the parameters to the original function (like tripler2) in most languages (even C.) Am I missing something here? There are places where I can use currying and partial application in my Grails application but I am hesitating to do so because I'm asking myself "How's that different?" Please enlighten me.

  • Languages/Methods to Learn for Scientific Computing?:

    - by Zéychin
    I'm a second-semester Junior working towards a Computer Science degree with a Scientific Computing concentration and a Mathematics degree with a concentration on Applied Discrete Mathematics. So, number crunching and such rather than a bunch of regular expressions, interface design, and networking. I've found that I'm not learning new relevant languages from my coursework and am interested in what the community would recommend me to learn. I know as far as programming methods go, I need to learn more about parallelizing programs, but if there's anything else you can recommend, I would appreciate it. Here's a list of the languages with which I am very experienced (web technologies omitted as they barely apply here). Any recommendations for additional languages I should learn would be very much appreciated!: Java C C++ Fortran77/90/95 Haskell Python MATLAB

  • Is functional programming a superset of object oriented?

    - by Jimmy Hoffa
    The more functional programming I do, the more I feel like it adds an extra layer of abstraction that seems like how an onion's layer is- all encompassing of the previous layers. I don't know if this is true so going off the OOP principles I've worked with for years, can anyone explain how functional does or doesn't accurately depict any of them: Encapsulation, Abstraction, Inheritance, Polymorphism I think we can all say, yes it has encapsulation via tuples, or do tuples count technically as fact of "functional programming" or are they just a utility of the language? I know Haskell can meet the "interfaces" requirement, but again not certain if it's method is a fact of functional? I'm guessing that the fact that functors have a mathematical basis you could say those are a definite built in expectation of functional, perhaps? Please, detail how you think functional does or does not fulfill the 4 principles of OOP.

  • Type dependencies vs directory structure

    - by paul
    Something I've been wondering about recently is how to organize types in directories/namespaces w.r.t. their dependencies. One method I've seen, which I believe is the recommendation for both Haskell and .NET (though I can't find the references for this at the moment), is: Type Type/ATypeThatUsesType Type/AnotherTypeThatUsesType My natural inclination, however, is to do the opposite: Type Type/ATypeUponWhichTypeDepends Type/AnotherTypeUponWhichTypeDepends Questions: Is my inclination bass-ackwards? Are there any major benefits/pitfalls of one over the other? Is it just something that depends on the application, e.g. whether you're building a library vs doing normal coding?

  • Permissions and MVC

    - by not-rightfold
    I’m in the progress of developing a web application. This web application is mostly a CRUD interface, although some users are only allowed to perform some actions and see only some parts of views. What would be a reasonable way to handle user permissions, given that some parts of views are not available to users? I was thinking of having a function hasPermission(permission) that returns true iff the current user has the given permission, although it would require conditionals around all parts of views that are only visible to some users. For example: {% if has_permission('view_location') %} {{ product.location }} {% endif %} I’m fearing this will become an ugly and unreadable mess, especially since these permissions can get kind of complicated. How is this problem commonly solved in web applications? I’m considering using Haskell with Happstack or Python with Django.

  • Functional programming readability

    - by Jimmy Hoffa
    I'm curious about this because I recall before learning any functional languages, I thought them all horribly, awfully, terribly unreadable. Now that I know Haskell and f#, I find it takes a little longer to read less code, but that little code does far more than an equivalent amount would in an imperative language, so it feels like a net gain and I'm not extremely practiced in functional. Here's my question, I constantly hear from OOP folks that functional style is terribly unreadable. I'm curious if this is the case and I'm deluding myself, or if they took the time to learn a functional language, the whole style would no longer be more unreadable than OOP? Has anybody seen any evidence or got any anecdotes where they saw this go one way or another with frequency enough to possibly say? If writing functionally really is of lower readability than I don't want to keep using it, but I really don't know if that's the case or not..
