  • What is your experience with Nitrogen on Erlang?

    - by Yuval A
    I've been checking out the Nitrogen Project which is supposed to be the most mature web development framework for Erlang. Erlang, as a language, is extremely impressive. However, with regards to Nitrogen, what I am not too keen about is using Erlang's rather uncommon syntax (unless you're native in PROLOG) to build UIs. What is your experience with it as opposed to other mainstream web frameworks such as Django or Rails?

  • assign subset of parent table to objects in R

    - by Brandon
    Hello, I would like to iterate through a table and break it into relvant parts based on the number of visits. I have tried several things but cannot seem to get it to work. I have included the code. for(i in 1:6){ paste("testing.visit",i,"\n",sep="") <- subset(testing,visit_no==2) } But I get the following error. Error in paste("testing.visit", i, "\n", sep = "") <- subset(testing, : target of assignment expands to non-language object Thank you, Brandon

  • A Turing Machine Question

    - by Hellnar
    Greetings, I have been struggling to find a question regarding this theoretical question, even tho it is not directly a programming question, I believe it is really related. Assume a type of Turing machine which cannot have more than 1000 squares. What would be the relationship between the set of such type of recognizable languages and set of normal recognizable languages.

  • What is the best beginner's guide to PHP?

    - by Ami
    I work a lot with Wordpress and I'm trying to customize some of my themes, all of which are written in PHP. I've been trying to learn this language for a little while, but I'm not an experienced coder (My knowledge only includes HTML with some CSS). Can you recommend a guide/book/tutorial/etc that would work for a beginner?

  • Recommended Clang command line options

    - by frou
    The Manual for Clang seems to be work in progress, so could you help me formulate the definitive command line options for compiling ANSI-C (AKA C89, C90) with maximum strictness and relevant/helpful warnings? Clang is a compiler front end for the C, C++, and Objective-C programming languages. It uses the Low Level Virtual Machine (LLVM) as its back end. It is still under development. Its goal is to offer a replacement to the GNU Compiler Collection (GCC)

  • Conditional or in C#

    - by vikitor
    Hello, I've been programming in JAVA and C all my years at Uni, but now I'm learning C# and building a small application, and I've found troubles with this: if (taxonType.Equals(null) ¦¦ taxonID == -1) I get a red underline for this conditional, and I don't really know why, because according to what I've seen that should be ok, but it is not. Is there something I'm missing? thank you all in advance, Victor

  • Programmatically measure size and way-order of L1 and L2 caches

    - by osgx
    How can I measure programmatically (not query the OS, but measure) the size and order of associativity of L1 and L2 caches (data caches)? Assumptions about system: It has L1 and L2 cache (may be L3 too, may be cache sharing), It may have a hardware prefetch unit (just like P4+), It has a stable clocksource (tickcounter or good HPET for gettimeofday). There are no assumptions about OS (it can be Linux, Windows, or something non-standard), and we can't use POSIX queries. Language is C. And compiler optimizations may be disabled.

  • Wildcard searching and highlighting with Solr 1.4

    - by andy
    Hey guys, I've got a pretty much vanilla install of SOLR 1.4 apart from a few small config and schema changes. <requestHandler name="standard" class="solr.SearchHandler" default="true"> <!-- default values for query parameters --> <lst name="defaults"> <str name="defType">dismax</str> <str name="echoParams">explicit</str> <str name="qf"> text </str> <str name="spellcheck.dictionary">default</str> <str name="spellcheck.onlyMorePopular">false</str> <str name="spellcheck.extendedResults">false</str> <str name="spellcheck.count">1</str> </lst> </requestHandler> The main field type I'm using for Indexing is this: <fieldType name="textNoHTML" class="solr.TextField" positionIncrementGap="100"> <analyzer type="index"> <charFilter class="solr.HTMLStripCharFilterFactory" /> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" /> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.SnowballPorterFilterFactory" language="English" protected="protwords.txt"/> </analyzer> <analyzer type="query"> <tokenizer class="solr.WhitespaceTokenizerFactory"/> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" enablePositionIncrements="true" /> <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="0" catenateNumbers="0" catenateAll="0" splitOnCaseChange="1"/> <filter class="solr.LowerCaseFilterFactory"/> <filter class="solr.SnowballPorterFilterFactory" language="English" protected="protwords.txt"/> </analyzer> </fieldType> now, when I perform a search using "q=search+term&hl=on" I get highlighting, and nice accurate scores. BUT, for wildcard, I'm assuming you need to use "q.alt"? Is that true? If so my query looks like this: "q.alt=search*&hl=on" When I use the above query, highlighting doesn't work, and all the scores are "1.0". What am I doing wrong? is what I want possible without bypassing some of the really cool SOLR optimizations. cheers!

  • WPF Coordinates of intersection from two Line objects

    - by Becky Franklin
    I have two Line objects in C# WPF, and I'm trying to construct a method to work out the coordinates at which the lines intersect (if at all). After giving myself a headache reminding myself of high school maths to do this, I can't work out how to map it into programming format - anyone know how to do this? Thanks very much, Becky

    Hi, I am trying get float value with UITextField. On the simulator V3.1.3 in English, I have to use '.' to separate my float values.

  • Change text of UIAlertView when recording a video with UIImagePickerController and reaching the videoMaximumDuration

    - by aimak
    I'd want to know how to change to text of the UIAlertView appearing when I record a video with a UIImagePickerController and I reach the videoMaximumDuration. If it is not possible to change the text of that UIAlertView, is it at least possible to display it in another language ? Edit : the default text is "The maximum length for this video has been reached" with title "Video Recording Stopped". Thank you, aimak

  • Python Mindstorms RCX

    - by Kyle Schmidt
    I've got 30 unopened Lego Mindstorms kits that I'd love to use in my intro programming class to do some simple robotics stuff at the end of the year. We're using Python in the class, so I'd prefer there to be a way for the kids to write the programs in Python. Unfortunately, these are old kits with RCX bricks - not the newer NXT ones, so most of the projects like NXT_Python can't help me. Is there any way to make that happen?

  • generating program structur (nodes) using bison and flex

    - by gruszczy
    I would like to write myself a pretty printer for java using bison and flex. I have written a pretty printer for a script language, but I was only writing visitors, which made the printing. How can I turn a program using my formal grammar into a tree of nodes (made using C++ classes), that afterwards I could visit using my visitor? Maybe you could give me some link with an example of this? What i need to put into flex/bison files?

  • What are 'len', 'dir', 'vars' named?

    - by johannix
    I was wondering what language to use when talking about a function that takes in a specific object, acts on it and returns something else. Clearly they're functions, but I was wondering if there's a more specific term. A couple examples of Python built-in functions that fit this spec are: 'len', 'dir', 'vars' I thought it was 'predicate', but apparently that's specific to functions that return a boolean value.

  • What is a 'thunk'?

    - by fbrereto
    I've seen it used in programming (specifically in the C++ domain) and have no idea what it is. Presumably it is a design pattern, but I could be wrong. Can anyone give a good example of a thunk?

    - by Chathuranga Chandrasekara
    I am in a need of programatically convert an Word-XML file into a RTF file. It has become a requirement, because of some third party libraries. Any API/Library that can do that? Actually the language is not a problem because I just need to work done. But Java, .NET languages or Python are preferred.
