• Why are there two different kinds of linking, i.e. static and dynamic?

  - by davidk01

  I've been bitten for the n-th time now by a library mismatch between a build and deployment environment. The build environment had libruby.so.2.0 and the deployment environment had libruby.a. One ruby was built with RVM, the other was built with ruby-build. The reason I ran into a problem was because zookeeper was compiled in a build environment that had the shared library but the deployment environment only had the static library. In all the years I've been writing application code I have never once wished that the binaries I was using where linked against shared objects. What is the reason the dichotomy persists to this day on modern operating systems?

• Managing .NET Deployment Configuration With Rake

  - by Liam McLennan

  Rake is a ruby internal DSL for build scripting. With (or without) the help of albacore rake makes an excellent build scripting tool for .NET projects. The albacore documentation does a good job of explaining how to build solutions with rake but there is nothing to assist with another common build task – updating configuration files. The following ruby script provides some helper methods for performing common configuration changes that are required as part of a build process.  class ConfigTasks def self.set_app_setting(config_file, key, value) ovsd_element = config_file.root.elements['appSettings'].get_elements("add[@key='#{key}']")[0] ovsd_element.attributes['value'] = value end def self.set_connection_string(config_file, name, connection_string) conn_string_element = config_file.root.elements['connectionStrings'].get_elements("add[@name='#{name}']")[0] conn_string_element.attributes['connectionString'] = connection_string end def self.set_debug_compilation(config_file, debug_compilation) compilation_element = config_file.root.elements['system.web'].get_elements("compilation")[0] compilation_element.attributes['debug'] = false end private def self.write_xml_to_file(xml_document, file) File.open(file, 'w') do |config_file| formatter = REXML::Formatters::Default.new formatter.write(xml_document, config_file) end end end To use, require the file and call the class methods, passing the configuration file name and any other parameters. require 'config_tasks' ConfigTasks.set_app_setting 'web.config', 'enableCache', 'false'

• How to register a domain for a beginner?

  - by garbage collection

  I've never registered a .com , .net like domain before, and I would like to do some research before doing so. I currently have a ruby on rails app running Heroku. Is there anything special I have to do prior to registering domain on my ruby on rails app at all? Or is it as easy as just inserting my current Heroku address to mask it with another .com or .net name? Is there some special features I should look for registering domain? Or is it typical for domain seller to just sell domain names only? Any recommendations on sellers? Thank you.

• What do I need to write a small game on Linux?

  - by Michas

  I want to make a simple game: 2d, single-player, without tons of animations and special effects. I am not interested in ready to use game engines, I want to learn to write some code in a quite universal language. I am using Linux (AMD64) and looking for something easy with nice library for games. I do not want to mix few languages, most of them are in fact fast enough themselves for my needs. Cross platform would be an advantage, however all I need is a good Linux support. I have been considering few solutions. Ruby + Language looks very nice. + I am going to learn Ruby. - I am afraid I can have problems with additional libraries. - This thread about game libraries for Ruby could be longer. SDL + C + It is used for games. + It is very easy to set up. + There is a lot of additional libraries. + It is cross-platform. - The solution is quite low level. - The language is sometimes quite hard to read. QT + C++ + It is very easy to set up. + The standard QT libraries supports everything I can possibly need. + It is cross-platform. + The documentation is good. - The compilation is slow. - The language looks horrible. - The size of standard QT libraries is too big to comprehend. Environment of web browser + I am going to learn something more about this environment. + It is somewhat used for games. + It is quite cross-platform. - It would be too much experimental. Java + It is used for games. + The standard Java libraries supports everything I can possibly need. + It is cross-platform. - It is quite hard to set up. - The size of standard Java libraries is too big to comprehend. - The source code in Java could look better. - I think I do not want to learn Java. Google Go + I am going to learn Google Go. - There is big problem with libraries. - The solution would be quite low level. Python + It looks some people do games in Python, according to this thread. + It looks there are probably more libraries than for Ruby. - The Ruby language looks better. - I think I do not want to learn Python. C++ + something else + It is used for games. + It would be probably cross-platform. + There is a lot of libraries. - I do not need C++ extensions over C. - Compilation could be slow, there are fast compilers for C, not for C++. Haskell + I am going to learn Haskell. - Many things about programming computer games looks too much imperative. - It looks I can have some problems with libraries. - Compilation (GHC) looks slow. There is probably something more to consider. Does anyone have experience in making small games for Linux in non mainstream solutions? Does anyone have an advice for me?

• Whats the scope of a c function defined within objective-c class?

  - by roja

  I was reading up about bypassing objective-c's messaging to gain performance (irrelevant to this specific question) when i found an interesting bit of code: #import <Cocoa/Cocoa.h> @interface Fib : NSObject { } - (long long) cFib: (NSUInteger) number; @end @implementation Fib // c implementation of fib long long cFibIMP(NSUInteger number) { return (number < 3) ? 1 : cFib(number - 1) + cFib(number - 2); } // method wrapper for c implementation of fib - (long long) cFib: (NSUInteger) number { return cFibIMP(number); } @end My question is; when using c function, within an objective-c object, what scope is the c function (cFibIMP in this particular case) placed in? Does the objective-c class encapsulate the c function removing change of name-clash or is the c function simply dumped into the global scope of the whole objective-c program?

• CentOS - Configuring Puppet to play nice with SELinux

  - by Mike Purcell

  I am running into an issue every time I attempt to start the puppetmasterd service, for which I receive the following error message: root@service1 ~ # -> /etc/init.d/puppetmaster start Starting puppetmaster: Could not prepare for execution: Got 1 failure(s) while initializing: change from absent to directory failed: Could not set 'directory on ensure: Permission denied - /etc/puppet/ssl [FAILED] Apparently there was a known issue with this scenario as outlined in this bug report, however in the bug report it states the issue has been resolved in selinux-policy-3.9.16-29.fc15, but the latest CentOS default upstream version is 3.7.19-155.el6_3.4. So I am trying to figure out the best solution. I can either create a local security policy to allow puppetmasterd the access it needs, or keep researching and install a newer version of selinux-policy outside of the default upstream channel.

• What's shell script's advantage over interpreted programming languages?

  - by Lai Yu-Hsuan

  (I'm not sure if it's a appropriate question here) Shell script, like bash, can do many things. It can call Unix programs, pipe their output, redirect I/O from/to files, control flow, check whether a file exists, etc. But a modern programming language, e.g, python and ruby, can also do these all. And their are (I think) more readable and maintainable. bash is worldwide spreaded. But many distributions have installed python interpreter, too. So what's the advantage of shell script? If I could write python, ruby or perl, is it worth to learn bash?

• How do you navigate and refactor code written in a dynamic language?

  - by Philippe Beaudoin

  I love that writing Python, Ruby or Javascript requires so little boilerplate. I love simple functional constructs. I love the clean and simple syntax. However, there are three things I'm really bad at when developing a large software in a dynamic language: Navigating the code Identifying the interfaces of the objects I'm using Refactoring efficiently I have been trying simple editors (i.e. Vim) as well as IDE (Eclipse + PyDev) but in both cases I feel like I have to commit a lot more to memory and/or to constantly "grep" and read through the code to identify the interfaces. As for refactoring, for example changing method names, it becomes hugely dependent on the quality of my unit tests. And if I try to isolate my unit tests by "cutting them off" the rest of the application, then there is no guarantee that my stub's interface stays up to date with the object I'm stubbing. I'm sure there are workarounds for these problems. How do you work efficiently in Python, Ruby or Javascript?

• Peer code review for full application

  - by bswinnerton

  My sincerest apologies if this is the wrong place to post something like this, but this seemed like the best fit. I was wondering if there are any websites or resources for a full site peer code review. I'm new to Ruby specifically and want to make sure that my logic is following the overall best standards. I've pieced together multiple different tutorials and I feel like while my understanding is getting better, it'd be great if the overall structure of such an application could be critiqued, and for someone that doesn't really know another Ruby developer - I find that I've run into a roadblock and don't want to develop bad habits now.

• Are there any free hit counters that don't track users?

  - by David Englund

  Are there any free services that increment a simple hit counter without tracking the users of the site? I would like to know how many visitors there are to my site, excluding bots. I don't need detailed information like unique visitors or where the user is from (in fact, that's exactly what I don't want). I have been researching free hit counters, and it seems that most (all?) of them display advertisements and their terms of service indicate that they can use the data they collect from the client site however they want. Google Analytics also does this and tracks users across sites. The site is static HTML, so an external link or iframe of some sort is easiest for me to implement. I could switch to a Ruby or Node.js back-end, in which case lots of other options open up (like Ruby impressionist and more low-level implementations), but my hosting service is pretty limited. If the answer to my question is simply "no," what are my other options?

• Where should I store and verify files manipulated by an app

  - by Alan W. Smith

  I'm working on a little Ruby script to move screenshots while renaming them based on a specific convention. I'll be writing tests to confirm the behavior. Ruby has lots of conventions for where to store files (e.g. the "spec" and "features" directories for RSpec and Cucumber, respectively), but I'm not finding best practices for storing files that will be acted upon by the tests. The same goes for a destination for the final copies of the files. So, the question in two parts is: Where should I store files that the test cases will use for a source input. Where should tests that need to write output files send them to.

• Most Useful New Technology?

  - by Craig Ferguson

  I'm looking to take a sort of sabbatical, and I'd love to use it to learn a new technology. My question is this: What's the most useful "new" technology for a software engineer to use? Node.js, iOS programming, Android, something else? I'd prefer to stay away from anything too new or experimental, since those are, in my experience, rarely actually used in professional production environments (for better or worse). Does anyone happen to have stats on how many jobs there are for each new technology or have anecdotes about how fun each one is? I've been using python/Django, so that's out, and it's similar to Ruby so i don't think learning Ruby would be that useful to expanding my skills. Anyone have any other ideas?

  I have few questions to ask about the following class #import <Cocoa/Cocoa.h> @interface SomeObject { NSString *title; } @property (retain) NSString *title; @end implementation SomeObject @synthesize title; -(id)init { if (self=[super init]) { self.title=[NSString stringWithFormat:@"allyouneed"]; } return self; } -(void)testMethod{ self.title=[[NSString alloc] init] ; } -(void)dealloc { self.title=nil; [super dealloc]; } In the .h file do we need to declare the title and sub when we add the property. is it not enough to add the @property (retain) NSString *title; line. 2.Do i need to autorelease both assignment to title in the init and testMethod. if So why? Can some one explain these things to me.

  I know lots of startups often go for practical, simple, efficient. So maybe tossing a Ruby program on a basic Apache server. Get some users up and running, etc. Then Ruby starts to not be fast enough, so they throw more servers at the problem? And load balancing or something? And then when stuff gets REALLY crazy, language changes, etc? I'm looking for someone who has cleanly and simply told their own company's story like this. Are there any good ones?

• Is it a good idea to run Redmine using Webrick through Nginx?

  - by Rohit

  The task here is to get Redmine setup for a small (<20) team. There may be a few users who would access the setup as business clients. I am familiar with setting up PHP for Apache, and recently, Nginx. I am not familiar with Ruby, Ruby-On-Rails, etc. I prefer to use the OS's (Ubuntu Linux LTS) package manager to install the different components as it takes care of dependencies and updates. I have setup Nginx with PHP-FPM successfully and am struggling with Redmine. As suggested here, I got Redmine running on port 3000. # /etc/init/redmine.conf # Redmine description "Redmine" start on runlevel [2345] stop on runlevel [!2345] expect daemon exec ruby /usr/share/redmine/script/server webrick -e production -b 0.0.0.0 -d And using the Nginx config on this page, I used Nginx to proxy requests to Webrick. server { listen 80; server_name myredmine.example.com; location / { proxy_pass http://127.0.0.1:3000; } } This works well locally. I wanted some opinions before trying this out on the live box (a 256 MB VPS). Further, should I use something like monit to monitor webrick for failure?
