  • Trying to move away from PHP/Yii: RoR, Python/Django or ASP.NET MVC? Your opinions please [closed]

    - by Örs
    I have a CS degree and I've been working as a web developer (front & backend) for about 2 years now. I've been working with PHP mostly because it was easy to pick up and find a job, but I've grown to dislike the language and want to try something new, and possibly get a better paying job. That last point is especially important because in my area (Romania/Eastern Europe) PHP jobs are mostly for people fresh out of college/high school, hence the pay is rather low. I've been working with the Yii framework which, if I understand correctly, borrows a lot from Ruby on Rails (convention over configuration, MVC, Active Record, scaffolding). Other than PHP I only know curly-brace languages (C/C++/Java) and bash so Python/Ruby might be a bit challenging. On the other hand I've been using Linux (with vim and recently Sublime Text 2) for almost 4 years now so Windows and a lack of a terminal would have its downsides as well. I'm leaning towards Python/Ruby because of my *nix bias (plus both look like fun), but I've heard great things about ASP.NET MVC as well. Any suggestions? PS: I think there are more jobs in ASP.NET around here, but that's not necessarily a plus, because there are a lot of CS graduates as well. tl;dr: Romanian PHP/Yii developer trying to move to Python/Django or Ruby/Rails or C#/ASP.NET MVC. Suggestions?

  • Creating dynamic plots

    - by geoff92
    I'm completely new to web programming but I do have a programming background. I'd like to create a site that allows users to visit, enter some specifications into a form, submit the form, and then receive a graph. I have a few questions about this, only because I'm pretty ignorant: Is there a good framework I should start in? I know a lot of java, I'm okay with python, and I learned Ruby in the past. I figure I might use ruby on rails only because I hear of it so often and I think I've also heard it's easy. If anyone has some other recommendation, please suggest. The user will be entering data into a form. I'm guessing the request they'll be making should be one of a GET request, right? Because I don't intend for any of the data they're entering to modify my server (in fact, I don't intend on having a database). The data the user inputs will be used to perform calculations involving lots of matrices. I've written this functionality in python. If I use ruby on rails, should it be instead written in Ruby? Somewhere I've heard that you can either place the load of the work on your server or on the client's computer. Since the code performs heavy math, which option is preferable? How do I alter the setup to either make the client do the work or my server? Should I be using a "cgi-bin"? In the code that I have now, I use matplotlib, a python library, and then "show" the plot in order to see the graph. I specify the x and y limits, but I am able to "drag" the graph in order to see more data within the plot window. Ultimately, I want a graph to be shown on my site with the drag functionality. Is this possible? What if the client drags the graph so far, more computations must be made? Thanks!

  • should/could i use ruby-on-rails 3 for my next project?

    - by fayer
    im new to ruby and ruby on rails. im on a new project and would really like to code in ruby. of course u have to use a framework like RoR for web development. so my question is if i should/could use ruby-on-rails 3 for this new project that i will start with in 2-3 weeks from now. are there tutorials for it? is it stable enough? well tested? cause one thing when entering something totally new, you need tutorials and books that teach you how to use it. i guess there arent a lot of sources for this information so maybe its better for me to use the latest stable version? what do you think? thanks

  • Sparxsystems Enterprise Architect and issuses/tasks tracking system?

    - by peperg
    We (developement team 4 upto 7 people) use Sparxsystems EA for requirement analysis, modeling etc. Do you know any well-working methods to use EA and some task/issue tracking system like Redmine/Mantis/Trac ? The problem is not to duplicate functionality (there are issues/tasks/changes in Redmine and EA) but to have some user friendly interface (preffered web) to manage tasks and issues. By user-friendly I mean "my tasks" page add effort / time tracking easy "add issue" by everyone (simple bug tracking system) mail notifications

  • Dynamic DateTimeRangeValidator using Enterprise Library 4.1?

    - by Toran Billups
    I'm trying to add a range of - 365 days and + 365 days but it appears that using this attribute in EL 4.1 only accepts a special ISO formatted string ... thus I can't simply add a normal string to this validation routine. <DateTimeRangeValidator(DateTime.Now.AddDays(2), DateTime.Now.AddDays(4))> _ I wanted to do something similar to the above - fyi Does anyone know how you can force this attribute to accept this ISO formatted string w/out hand coding this value?

  • 640 enterprise library caching threads - how?

    - by JohnW
    We have an application that is undergoing performance testing. Today, I decided to take a dump of w3wp & load it in windbg to see what is going on underneath the covers. Imagine my surprise when I ran !threads and saw that there are 640 background threads, almost all of which seem to say the following: OS Thread Id: 0x1c38 (651) Child-SP RetAddr Call Site 0000000023a9d290 000007ff002320e2 Microsoft.Practices.EnterpriseLibrary.Caching.ProducerConsumerQueue.WaitUntilInterrupted() 0000000023a9d2d0 000007ff00231f7e Microsoft.Practices.EnterpriseLibrary.Caching.ProducerConsumerQueue.Dequeue() 0000000023a9d330 000007fef727c978 Microsoft.Practices.EnterpriseLibrary.Caching.BackgroundScheduler.QueueReader() 0000000023a9d380 000007fef9001552 System.Threading.ExecutionContext.runTryCode(System.Object) 0000000023a9dc30 000007fef72f95fd System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object) 0000000023a9dc80 000007fef9001552 System.Threading.ThreadHelper.ThreadStart() If i had to give a guess, I'm thinkign that one of these threads are getting spawned for each run of our app - we have 2 app servers, 20 concurrent users, and ran the test approximately 30 times...it's in the neighborhood. Is this 'expected behavior', or perhaps have we implemented something improperly? The test ran hours ago, so i would have expected any timeouts to have occurred already.

  • Enterprise Eclipse Provisioning - Or - How to share your standard Eclipse setup with other developer

    - by nikhil
    We use Eclipse as the IDE for developing all sorts of Java/J2EE applications in our 150 people odd IT department. One of the common problems we have been seeing is that developers download and install different versions of Eclipse and plugins based on their personal likes and dislikes. We have been trying to bring some consistency to this and have standardized on the version and the plugins that developers should be using. So the problem now is how do we distribute this installation to the team. We have zipped the directories and shared it through a shared drive. But I am looking for a better solution using some kind of provisioning tool for Eclipse using which people can install the IDE or get updates. Has anyone faced this problem? What are your solutions to this? How do you ensure a standard Eclipse environment across developers? I found Yoxos as a potential solution to this. Does anyone have any experience with it? Can p2 be used to do this?

  • Multiple Configuration Sources for Enterprise Library 4.1?

    - by Martijn B
    Hi All, We use the caching and logging application blocks from entlib 4.1. We want to keep the configuration of those two in seperate files. How can we achieve this? It looks like entlib is always using the selectedSource as it configuration. I tried the following: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="enterpriseLibrary.ConfigurationSource" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ConfigurationSourceSection, Microsoft.Practices.EnterpriseLibrary.Common, Version=4.1.0.0, Culture=neutral, PublicKeyToken=9057346a2b2dcfc8" /> </configSections> <enterpriseLibrary.ConfigurationSource selectedSource="messagesCache"> <sources> <add name="messagesCache" filePath="Configuration\\messagesCache.config" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=4.1.0.0, Culture=neutral, PublicKeyToken=9057346a2b2dcfc8" /> <add name="logging" filePath="Configuration\\logging.config" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=4.1.0.0, Culture=neutral, PublicKeyToken=9057346a2b2dcfc8" /> </sources> </enterpriseLibrary.ConfigurationSource> </configuration> But this doesn't work because the application blocks always use the selectedSource attribute value. Any suggestions woulde be welcome! Gr Martijn

  • How does ruby's rb_raise stop the execution of the c function calling it?

    - by Adrian
    If you write a ruby method as a function in C that uses rb_raise, the part of the function after the call will not get excecuted and the program will stop and you will think that rb_raise used exit(). But if you rescue the exception in ruby, like: begin method_that_raises_an_exception rescue end puts 'You wil still get here.' The ruby code will go on, but your function will stop excecuting. How does rb_raise make this happen?

  • Log to rolling CSV file with Enterprise Library

    - by Tinminator
    Need logging to: Rolling file, to avoid 1 big log file. CSV format for easier look up. I can see EntLib (5.0) have Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener to log to rolling log file. To make the log entries look like a CSV row, I can change the Logging.Formatters.TextFormatter.Template to put double quote around the values. Also change the Listener's Footer and Header to nothing, so they won't be output. Under normal circumstance, this would give me a well formed CSV file. However if a token value in the Template contain double quote, this would not be escaped, hence the log file become an invalid CSV file. Is there any way to resolve this? Is there any alternative solutions to this problem?

  • Enterprise library Validation block and rulesets

  • What are the most active Ruby forums/blogs on the web?

    - by MOZILLA
    I have just spent 2 days with Ruby, and my observation in last two days is that it is very difficult (as compared to say .NET/Java) to find an active forum/blogs which are helpful for Ruby (or maybe I don't know them since I am new). Which are the most common forums/blogs developers visit when they need help with Ruby (other than Stack Overflow)?

  • Adventures on Enterprise Library 5.0: Who moved my cheese (namespace)

    - by Junior Mayhé
    Jesus, Krishna, Budda! I've migrated to EntLib 5.0, but classes like ISymmetricCryptoProvider are not recognized anymore. Funny to say that Data, Logging and other blocks are working compiling fine. Here's the problematic class: using System; using System.Collections.Generic; using System.Text; using Microsoft.Practices.EnterpriseLibrary.Common.Configuration;//-->it's not working anymore using Microsoft.Practices.EnterpriseLibrary.Security.Cryptography;//-->it's not working anymore namespace MyClassLibrary.Security.EnterpriseLibrary { public sealed class Crypto { public static ISymmetricCryptoProvider MyProvider { get { //IConfigurationSource is not recognized either, neither SystemConfigurationSource IConfigurationSource cs = new SystemConfigurationSource(); SymmetricCryptoProviderFactory scpf = new SymmetricCryptoProviderFactory(cs); ISymmetricCryptoProvider p = scpf.CreateDefault(); return p; } } The references are fine on project too. I really don't know why this particular project it's causing too many trouble on VS2010! Older references were deleted, project was cleaned, rebuilt, but can't make it compile :-( The references are: Microsoft.Practices.EnterpriseLibrary.Common Microsoft.Practices.EnterpriseLibrary.Logging Microsoft.Practices.EnterpriseLibrary.Logging.Database Microsoft.Practices.EnterpriseLibrary.Security Microsoft.Practices.EnterpriseLibrary.Security.Cryptography Why some namespaces can be found while others can't?

  • How do you pipe output from a Ruby script to 'head' without getting a broken pipe error

    - by dan
    I have a simple Ruby script that looks like this require 'csv' while line = STDIN.gets array = CSV.parse_line(line) puts array[2] end But when I try using this script in a Unix pipeline like this, I get 10 lines of output, followed by an error: ruby lib/myscript.rb < data.csv | head 12080450 12080451 12080517 12081046 12081048 12081050 12081051 12081052 12081054 lib/myscript.rb:4:in `write': Broken pipe - <STDOUT> (Errno::EPIPE) Is there a way to write the Ruby script in a way that prevents the broken pipe exception from being raised?

  • Why isn't my Ruby object deleted when the last reference goes out of scope?

    - by Andrew Clegg
    Hi gurus, I've found a weird effect when trying to track down a memory leak in a Rails app. Can anyone explain what's going on here? Save this script as a plain Ruby script (Rails not necessary): class Fnord def to_s 'fnord' end end def test f = Fnord.new end test GC.start sleep 2 ObjectSpace.each_object do |o| puts o if o.is_a? Fnord end When I run this via ruby 1.8.7 (2009-06-12 patchlevel 174) [i486-linux] I get the following: bash $ ruby var_test fnord Although the variable f is out of scope, there are no other references to the single Fnord object, and I've garbage collected, the object still seems to exist. Is this a nefarious memory leak of some sort, or am I completely missing something about Ruby? Further, if I change the test method to this: def test f = Fnord.new f = nil end I get no output. But surely this should not change the semantics here? Many thanks!

  • What's the best way to mix Ruby and other languages? (Especially C++)

    Hi, I'm learning Ruby, and I'm starting to play with building extensions in C. I have Programming Ruby The Pragmatic Programmers' Guide and so I can follow that for the basic nuts and bolts. What I was wondering is if there already existed some nifty frameworks/whatever to help interoperability between Ruby and other languages, with C++ being the most important for me. I've tried googling, but the results focus on language comparisons, rather than language interoperability. TIA, Andy

  • Using Ruby on Rails, can a polymorphic database be created in a few steps (with polymorphic associat

    I thought it could be created in a few steps but it can't yet: rails poly cd poly ruby script/generate scaffold animal name:string obj_type:string obj_id:integer rake:migrate ruby script/generate scaffold human name:string passportNumber:string rake:migrate ruby script/generate scaffold dog name:string registrationNumber:string rake:migrate and now change app/models/animal.rb to: class Animal < ActiveRecord::Base belongs_to :obj, :polymorphic => true end and run ruby script/server and go to http://localhost:3000 I thought on the server then if I create an Michael, Human, J123456 and then Woofie, Dog, L23456 then the database will have entries in the Dogs table and "Humen" or "Humans" table as well as in the Animals table? But only the Animals table has records, Dogs and "Humen" do not for some reason. Is there some steps missing?
