  • Podcasts for Clojurians?

    - by Michiel Borkent
    I regularly listen to the podcasts DotNetRocks and Software Engineering Radio. Lately I have become more interested in Clojure. Are there any podcasts that target more toward the Clojure (more general FP/LISP/dynamic languages) audience? I know of some single podcast episodes but I'm looking for a podcast I can regularly listen to.

    - by Werner
    Hi, this is probably a very stupid question; in a bash script, given the output of, for instance; awk '{print $7}' temp it gives 0.54546 I would like to give this to a variable, so I tried: read ENE <<< $(awk '{print $7}' temp) but I get Syntax error: redirection unexpected Could you tell me why, and what is the easiest way to do this assignment? Thanks

  • How to add a jar build by a project to the project in eclipse?

    - by Xetius
    I have a project which as part of the build process creates an XMLBeans jar file (stbSchemas.jar) which I want to include and reference in this project. Is this the best way to go about this (Single project) or should I have a child project which is built from the parent project? I am building this using Maven2 inside Eclipse. Is there a better way to do this so that I can maintain the integrity of the projects and stability of the builds.

  • Indent or comment several text lines with VI

    - by Werner
    Hi, can vim or vim be used to comment or indent at the same time a number of lines? For instance: for item in Lista: ind = int(floor(1.0*(item-lmin)/width)) if ind==nintervals: ind=ind-1 print item,ind comment it to: #for item in Lista: #ind = int(floor(1.0*(item-lmin)/width)) #if ind==nintervals: #ind=ind-1 #print item,ind or indent it to: for item in Lista: ind = int(floor(1.0*(item-lmin)/width)) if ind==nintervals: ind=ind-1 print item,ind Thanks P.D.

    - by Luke

  • Synthesized property of a protocol not seeing superclass' ivar

    - by hyn
    I have a situation where my subclass is not seeing the superclass' instance variable x. The ivar is obviously @protected by default, so why do I get a compiler error "x undeclared"? - (CGSize)hitSize { // Compiler error return size; } EDIT: hitSize is a property of a protocol my subclass is conforming to. The problem was that I had hitSize @synthesized, which was the culprit. The question then is why can't the synthesized getter see the ivar?

    - by TheVillageIdiot
    Suppose I've following Code: Console.WriteLine("Value1: " + SomeEnum.Value1.ToString() + "\r\nValue2: " + SomeOtherEnum.Value2.ToString()); Will Compiler Optimize this to: Console.WriteLine("Value1: " + SomeEnum.Value1 + "\r\nValue2: " + SomeOtherEnum.Value2); I've checked it with IL Disassembler and there are calls to IL_005a: callvirt instance string [mscorlib]System.Object::ToString() I don't know if JIT optimizes this.

  • Is it possible to make a subclass of NSObject which support subnodes in IB for iPhone project?

    - by Eonil
    I'm making a custom UI element class for iPhone. It'll cool to edit my class on Interface Builder with hierarchy. Some of my class is management class like UINavigationController, but they're not one of them, subclasses from NSObject. Of course, I can place a NSObject instance on IB, but it cannot have a child node. Is there a way to enable adding child node to subclass of NSObject?

  • Is copying /var/lib/mysql a good alterntive to mysqldump?

    - by kemp
    Since I'm making a full backup of my entire debian system, I was thinking if having a copy of /var/lib/mysql directory is a viable alternative to dumping tables with mysqldump. are all informations needed contained in that directory? can single tables be imported in another mysql? can there be problems while restoring those files on a (probably slightly) different mysql server version?
