  • when was Kase born?

    - by Horace Ho
    First time I saw a class Kase, I was scratching my head. My guess it's something to do with a conflict of the keyboard case. BTW, since when, for which language(S), it becomes a norm?

  • Double Timezone offset

    - by gAMBOOKa
    I have a timezone name and I want the name of the timezone double its offset. For instance, Asia/Dubai is +4, I want to double that to +8... and have it resolved to Asia/HonkKong Language: PHP Here's a sample of what it would look like: $timezone = "Asia/Dubai" $offset = $timezone->getOffset(); $offset *= 2; $timezone = $offset->getTimeZone(); Output: Asia/HonkKong

  • Is Ruby on Rails slow with medium traffic?

    - by IHawk
    Hello ! I made some searches on Google, and I read some posts, articles and benchmarks about Ruby on Rails being slow and I am planning to build one website that will have a good amount of users inserting data and there will be some applications to process this data (maybe in Ruby, you can help me choosing the language). What is the real performance of Ruby on Rails with large traffic ? Thank you !

  • What Causes Boost Asio to Crash Like This?

  • 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?

  • Http 400 'Bad Request' and win32status 1450 when larger messages are sended to a WCF service

    - by Tim Mahy
    we sometimes receive Http 400 bad request resultcodes when posting a large file (10mb) to a WCF service hosted in IIS 6. We can reproduce this using SOAP UI and it seems that it is unpredictable when this happens. In our WCF log the call is not received, so we believe that the request does not reach the ASP.NET nor WCF runtime. This happens on multiple websites on the same machine each having their own application pool. All IIS settings are default, only in ASP.NET and WCF we allow bigger readerQuota's etc.... The win32status that is logged in the IIS log is 1450 which we think means "error no system resources". So now the question: a) how can we solve this b) (when a is not applicable :) ) which performance counters or logs are usefull to learn more about this problem? greetings, Tim

    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

  • Tips for learning faster

    - by Helper Method
    When I start to learn something new, a new tool, programming language, etc. it often takes me sooo much time to learn it. In the end, I have a deep understanding (well, most of the time ;-)), but lacking the time for other things also important. Do you know any tips to learn faster without sacrificing too much depth?

  • What C++ pitfalls should I avoid ?

    - by Craig H
    I remember first learning about vectors in the STL and after some time, I wanted to use a vector of bools for one of my projects. After seeing some strange behavior and doing some research, I learned that a vector of bools is not really a vector of bools. Anyone out there have any other common pitfalls to avoid in C++?

  • why does vb not support multiple inheritance?

    - by isolatedIterator
    I've seen some discussion on why c# does not implement multiple inheritance but very little as to why it isn't supported in vb. I understand that both c# and vb are compiled down to intermediary language and so they both need to share similar restrictions. The lack of multiple inheritance in VB seems to have been given as one reason for the lack of the feature in dot net. Does anyone know why VB doesn't support multiple inheritance? I'm hoping for a bit of history lesson and discussion on why this was never considered for VB.

  • Any other kinds of "Task Queue" APIs ?

    - by sork
    I'm curious if it's common practice outside of the GAE platform to be able to defer tasks to background workers via webhooks. I find it particularly useful to speed up the front-end of webapps, by delegating any long process to background tasks. I'd like to hear about open source software allowing to implement a TaskQueue-like API, with webhooks preferably, if anyone has some experience in this area. Thanks!

  • Make NetBeans automatically include newline at end of file?

    - by keithjgrant
    I just switched to NetBeans (6.8) and have noticed some of my files don't end with a newline. This has been a helpful option in other IDEs I've used, but I haven't been able to find it in the NetBeans options menus. Is it buried in there somewhere or is there any other way to make sure it always saves files with a newline at the end? I'm coding primarily in PHP, if it's available in any of the language-specific options.

  • 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?

  • Why is Microsoft not developing a Halo-like next gen title using C#? [closed]

    - by Joan Venge
    The question might look subjective but considering Microsoft: Owns the Xbox 360 platform Owns the Windows platform Have their own game studio (MGS) Own other 3rd party developers Is a major publisher makes me wonder why Microsoft doesn't push their flagship language to prove that not only you can cut down significant development time, and therefore money, but also show that you can release a next gen title where the real time interactivity doesn't suffer. If Microsoft were to do this once, I am sure many AAA developers would jump on that wagon too.

  • Snippets in Vim not working

    - by donut
    I've been trying to get snippets to work with Vim (specifically, MacVim). I have tried both snippetsEmu and snipMate (preferred). Other plugins are working fine. I have been able to get snippetsEmu to temporarily work via A Byte of Vim's note to run :runtime! ftplugin/python_snippets.vim if they aren't working, except the author doesn't mention why they may not be working or what kind of permanent solutions are available. So, basically when I type for<tab> in a PHP file it just puts a tab after 'for' instead of expanding into the snippet. I'm new to Vim and can't seem to figure this out. The only main difference that these two plugins (snippetsEmu and snipMate) have compared to other plugins is that they use the ~/.vim/after directory. But knowing that hasn't helped me any. What I have seen some people suggest is to make sure the following is in your .vimrc file, but this has not helped: set nocompatible filetype on filetype plugin on

  • NHibernate complex one-to-one mapping

    - by Eugene Strizhok
    There is a table A containing common unversioned data for entities. There are also tables B,C,D with versioned data of particular entity type. All of these tables are referencing table A. The task is to add a mapping of a property of entity's type, for example, stored in table B, which would reference table A, and specify a rule how entity should be fetch from table B based on identifier from table A. (For example, to fetch latest version of an entity). It it possible with NHibernate?

  • Visual Studio support for coding directly in *IL?

    - by jdk
    For the longest time I've been curious to code in Intermediate Language just as an academic endeavour and to gain a better understanding of what's "happening under the hood". Does anybody provide Visual Studio support for *IL in the form of: project templates, IntelliSense integration, and those kind of RAD features? Edits: I don't mean restricted to out of the box support. For example, I can download Visual Studio extensions to support Python, COBOL, etc. Want the same for *IL. There is a stand-alone Intermediate Assembler tool.
