  • Is there a good date/time API available for Scala?

    - by Erik Engbrecht
    I'm looking for something akin to JodaTime or JSR 310 for Scala that leverages nice Scala features such as operator overloading and doesn't rely on implicit conversions (I have an irrational fear of implicit conversions). I'm aware of http://github.com/jorgeortiz85/scala-time, but it just pimps JodaTime with implicits.

  • Group by in Winforms/webforms DataGrid

    - by Kumar
    I'd like to implement the group by features for the default grid as it's available for the commercial grid like devexpress/infragistics et al, if you want a sample, see the 2nd image on http://www.devexpress.com/Products/NET/Controls/WinForms/Grid/dataoperations.xml I'd think there's some pattern or better yet some opensource/free grid which does this already, if not, i would probably implement it if i can find the time (doubtful ! and esp since it's available so easily in most packages, if only i can convince the client to pay for a license ) & want to get some ideas/patterns on the same

  • operator "new" returning a non-local heap pointer for only one class ?

    - by KaluSingh Gabbar
    Language : C++ Platform : Windows Server 2003 I have an exe calling a DLL, in which when I allocate (new) the memory for class A (which is in DLL) it returns me a non-local heap pointer. I try to new other classes which are in DLL and "new" returns a valid heap pointer for them, its only Class A which is not being allocated properly. I am on windows and validating the heap by this function call : _CrtIsValidHeapPointer ( (const void *) pPtr ) I am seriously confused why this only happens with new-ing Class A and no other class ? (All Native Code)

  • Why hasn't MSSQL made a WHERE clause mandatory by default?

    - by Josh Einstein
    It seems like a no brainer to me. I've heard countless stories about people forgetting the WHERE clause in an UPDATE or DELETE and trashing an entire table. I know that careless people shouldn't be issuing queries directly and all that... and that there are legitimate cases where you want to affect all rows, but wouldn't it make sense to have an option on by default that requires such queries to be written like: UPDATE MyTable SET MyColumn = 0 WHERE * Or without changing the language, UPDATE MyTable SET MyColumn = 0 WHERE 1 = 1 -- tacky, I know

  • Benchmarking Java programs

    - by stefan-ock
    For university, I perform bytecode modifications and analyze their influence on performance of Java programs. Therefore, I need Java programs---in best case used in production---and appropriate benchmarks. For instance, I already got HyperSQL and measure its performance by the benchmark program PolePosition. The Java programs running on a JVM without JIT compiler. Thanks for your help! P.S.: I cannot use programs to benchmark the performance of the JVM or of the Java language itself (such as Wide Finder).

  • What is your most irritating quirk of t-sql

    - by Jude Wood
    I realise this is a bit flippant but it may highlight some 'interesting' features of t-sql. Or just provide some light distraction on a Friday morning... I'm currently torn between t-sql allows three part naming when dropping tables but not when dropping procudures and When using Coalesce to produce a delimited string the presence of a leading delimiter is dependant on whether the delimited string was initialised prior to calling Coalesce I'd be interested to hear yours......

  • Cant get description rss tag data with javascript

    - by AdamB
    I'm currently making a widget to take and display items from a feed. I have this working for the most part, but for some reason the data within the tag within the item comes back as empty, but I get the data in the and tags no problem. feed is and xmlhttp.responseXML object. var items = feed.getElementsByTagName("item"); for (var i=0; i<10; i++){ container = document.getElementById('list'); new_element = document.createElement('li'); title = items[i].getElementsByTagName("title")[0].firstChild.nodeValue; link = items[i].getElementsByTagName("link")[0].firstChild.nodeValue; alert(items[i].getElementsByTagName("description")[0].firstChild.nodeValue); new_element.innerHTML = "<a href=\""+link+"\">"+title+"</a> "; container.insertBefore(new_element, container.firstChild); } I have no idea why it wouldn't be working for the tag and would be for the other tags. Here is an example of the rss feed its trying to parse: <rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/"> <channel> <title>A title</title> <link>http://linksomehwere</link> <description>The title of the feed</description> <language>en-us</language> <item> <pubDate>Fri, 10 Jul 2009 11:34:49 -0500</pubDate> <title>Awesome Title</title> <link>http://link/to/thing</link> <guid>http://link/to/thing</guid> <description> <![CDATA[ <p>some html crap</p> blah blah balh ]]> </description> </item> </channel> </rss>

  • Is MapReduce one form of Continuation-Passing Style (CPS)?

    - by Jeffrey
    As the title says. I was reading Yet Another Language Geek: Continuation-Passing Style and I was sort of wondering if MapReduce can be categorized as one form of Continuation-Passing Style aka CPS. I am also wondering how can CPS utilise more than one computer to perform complex computation. Maybe CPS makes it easier to work with Actor model.

  • Looking for an Open Source Project in need of help

    - by hvidgaard
    Hi StackOverflow! I'm a CS student on well on my way to graduate. I have had a difficult time of finding relevant student jobs (they seems to be taken merely hours after the notice gets on the board) , so instead I'm looking for an open source project in need of help. I'm aware that I should choose one that I use, but I'm not aware of any OS-project that I use that needs help. That's why I'm asking you. I don't have any deep experience, but I here are some of my biggest projects so far: BitTorrent-ish client in Python (a subset of BitTorrent) HTTP 1.1 webserver in Java Compiler from a subset of Java to run on JRE Flash-framework project to model an iPad look and feel (not to run actual iPad programs) complete with an API for programs. Complete MySQL database for a booking system, with departure and arrival times, so you could only book valid tickets (with a Java frontend). I know, Java and languages like AS3 and C# feels natural per se, Python, and have done a fair bit of hacking around in C, but I don't feel very comfortable with it. Mostly I'm afraid to make a fuckup because I have such a high degree of control. I would like to think I'm well aware of good software design practices, but in reality what I do is ask myself "would I like to use/maintain this?", and I love to refactor my code because I see optimizations. I love algorithms and to make them run in the best possible time. I don't have any preferred domain to work in, but I wouldn't mind it to be graphics or math heavy. Ideally I'm looking for a project in C++ to learn the in's and out's of it, but I'm well aware that I don't know that language very well. I would like to have a mentor-like figure until I'm confident enough to stand on my own, not one to review all my code (I'm sure someone will to start with anyway), but to ask questions about the project and language in question. I do have a wife and two children, so don't expect me to put in 10+ hours every week. In return I can work on my own, I strive to program modular and maintainable code. Know how to read an API, use Google, StackOverflow and online resources in general. If you have any questions, shoot. I'm looking forward to your suggestions.
