  • Highly scalable and dynamic "rule-based" applications?

    - by Prof Plum
    For a large enterprise app, everyone knows that being able to adjust to change is one of the most important aspects of design. I use a rule-based approach a lot of the time to deal with changing business logic, with each rule being stored in a DB. This allows for easy changes to be made without diving into nasty details. Now since C# cannot Eval("foo(bar);") this is accomplished by using formatted strings stored in rows that are then processed in JavaScript at runtime. This works fine, however, it is less than elegant, and would not be the most enjoyable for anyone else to pick up on once it becomes legacy. Is there a more elegant solution to this? When you get into thousands of rules that change fairly frequently it becomes a real bear, but this cannot be that uncommon of a problem that someone has not thought of a better way to do this. Any suggestions? Is this current method defensible? What are the alternatives? Edit: Just to clarify, this is a large enterprise app, so no matter which solution works, there will be plenty of people constantly maintaining its rules and data (around 10). Also, The data changes frequently enough to say that some sort of centralized server system is basically a must.

  • How many developers actually have private offices?

    - by Prof Plum
    So I know everyone here is all about private offices, how many developers actually have them. I am sort of half skeptical. I can believe that lead developers have them, but thats normally just one person in your average office. If it would not be to much to ask: Do you work in a totally awesome office or a nasty old cube? (or somewhere in between) What's your relative rank in the office? (junior, programmer II, senior, lead, etc.) are you doing internal software, or are you in a software-centric environment? (the general thought seems to be that internal developers get cubes while others live in "Joel-Spolsky-Programmer-Candyland")

  • Is type safety worth the trade-offs?

    - by Prof Plum
    I began coding in in Python primarily where there is no type safety, then moved to C# and Java where there is. I found that I could work a bit more quickly and with less headaches in Python, but then again, my C# and Java apps are at much higher level of complexity so I have never given Python a true stress test I suppose. The Java and C# camps make it sound like without the type safety in place, most people would be running into all sorts of horrible bugs left an right and it would be more trouble than its worth. This is not a language comparison, so please do not address issues like compiled vs interpreted. Is type safety worth the hit to speed of development and flexibilty? WHY? to the people who wanted an example of the opinion that dynamic typing is faster: "Use a dynamically typed language during development. It gives you faster feedback, turn-around time, and development speed." - http://blog.jayway.com/2010/04/14/static-typing-is-the-root-of-all-evil/

  • UppercuT &ndash; Custom Extensions Now With PowerShell and Ruby

    Arguably, one of the most powerful features of UppercuT (UC) is the ability to extend any step of the build process with a pre, post, or replace hook. This customization is done in a separate location from the build so you can upgrade without wondering if you broke the build. There is a hook before each step of the build has run. There is a hook after. And back to power again, there is a replacement hook. If you dont like what the step is doing and/or you want to replace its entire functionality,...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Programming *into* a language vs. writing C code in Ruby

    - by bastibe
    Code Complete states that you should aways code into a language as opposed to code in it. By that, they mean Don't limit your programming thinking only to the concepts that are supported automatically by your language. The best programmers think of what they want to do, and then they assess how to accomplish their objectives with the programming tools at their disposal. (chapter 34.4) Doesn't this lead to using one style of programming in every language out there, regardless of the particular strengths and weaknesses of the language at hand? Or, to put the question in a more answerable format: Would you propose that one should try to encode one's problem as neatly as possible with the particulars of one's language, or should you rather search the most elegant solution overall, even if that means that you need to implement possibly awkward constructs that do not exist natively in one's language?

  • In what oreder does the Asset-Pipeline in Ruby on Rails load JavaScript Files?

    - by psycatham
    Hello, So, when I decided to remove the tags <script></script> and benefit from the asset-pipeline instead, complications took place. I am working with Google Maps' API V3, and to benefit from their functions and objects that their code provides, you have load the link first <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places"></script> Basically, If I put this line before their code, and put their code in script tags, things work out pretty perfecty, but when I use javascript_include_tag instead of script tag in html and copy my code to the file I pointed at -Like This - <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places"></script> <%=javascript_include_tag "map_new_marker_drag"%> , the asset-pipeline seems to load That file before loading the link of Google Maps API, thus I get the error : - Uncaught ReferenceError : google is undefined I tried putting the link in javascript_include_tag too -Like this- <%=javascript_include_tag "https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places" %> <%=javascript_include_tag "map_new_marker_drag"%> , and it generated this <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&amp;libraries=places"></script> <script src="https://maps.gstatic.com/cat_js/intl/en_us/mapfiles/api-3/17/2/%7Bmain,places%7D.js" type="text/javascript"></script> <script src="/assets/map_new_marker_drag.js?body=1"></script> and the same error Uncaught ReferenceError : google is undefined. Do I have to put it in another order? what am I missing about the asset-pipeline mechanisms ? What should I do to make the link load before the code so to benefit from their objects and get rid of the error? PS : I tried using jquery functions and so , but I seem not to make it happen. If you still think this is a proper solution, please provide me some code I can use this is the jquery function I used jQuery(function($) { // Asynchronously Load the map API var script = document.createElement('script'); script.src = "http://maps.googleapis.com/maps/api/js?sensor=false&callback=initialize"; document.body.appendChild(script); var scriptTwo = document.createElement('script'); scriptTwo.src = "https://maps.googleapis.com/maps/api/js?v=3.exp&libraries=places"; document.body.appendChild(scripTwo); });

  • Is an 'if password == XXXXXXX' enough for minimum security?

    - by Prof Plum
    If I create a login for an app that has middle to low security risk (in other words, its not a banking app or anything), is it acceptable for me to verify a password entered by the user by just saying something like: if(enteredPassword == verifiedPassword) SendToRestrictedArea(); else DisplayPasswordUnknownMessage(); It seems to easy to be effective, but I certainly would not mind if that was all that was required. Is a simple check on username/password combo enough? Update: The particular project happens to be a web service, the verification is entirely server side, and it is not open-source. Does the domain change how you would deal with this?

  • rake test:units fails with status ()

  • How to protect Ruby on Rails code on external server?

    - by Phil Byobu
    I have to deploy a Ruby on Rails Applications on a client's server and I do not want them to be able to view or modify the source code. How would you protect the code technically? I thought about building a linux-based virtual machine with an encrypted filesystem where the application code resides. The client has no root access, or direct access to the system at all. All services start automatically and the application is ready to use. What would you suggest?

  • Debian 6 or CentOS 6 - which one is easiest for latest versions of Ruby and Postgres?

    - by A4J
    I am getting a new server as I've messed up my current box, while trying to install Postgres 9 (on my CentOS 5.8 box). To cut a long story short, I removed postgres but yum decided to remove virtualmin-base as well, which broke my virtualmin install (postfix/dovcot stopped working). Virtualmin advise a fresh install once virtualmin-base has been removed/reinstalled. So I'll probably make a decision based on this simple criteria: which distro out of the two makes it easiest for installing the latest versions of Ruby and Postgres? They are both equally respected as web servers, so I really don't mind either way - I just want to use the one that will work best with the software I need.

  • Watir with IronRuby!

    - by azamsharp
    Has anyone used Watir with IronRuby successfully? I am getting an error that the required file 'Watir' was not found. What path do I need to set to get this file to work in IronRuby? For some reason my igem command is not working: C:\DevTools\IronRuby\ironruby\Merlin\Main\Languages\Ruby\Scripts\binigem instal l watir '"C:\DevTools\IronRuby\ironruby\Merlin\Main\Languages\Ruby\Scripts\bin\ir.exe"' is not recognized as an internal or external command, operable program or batch file. I am using 0.9 version of Ironruby. I remember that in 0.9 you have to indicate the ir tool: I used the following and got the error again! C:\DevTools\IronRuby\ironruby\Merlin\Main\Languages\Ruby\Scripts\binir igem ins tall watir ERROR: While executing gem ... (RangeError) bignum too big to convert into Fixnum The current version of RubyGems is 1.3.5: C:\DevTools\IronRuby\ironruby\Merlin\Main\Languages\Ruby\Scripts\binir igem -v 1.3.5 I even tried using the full path: require File.dirname(__FILE__) + "C:/ruby/lib/ruby/gems/1.8/gems/commonwatir-1.6.2/lib/watir.rb"

  • How can you get the call tree with python profilers?

    - by Oliver
    I used to use a nice Apple profiler that is built into the System Monitor application. As long as your C++ code was compiled with debug information, you could sample your running application and it would print out an indented tree telling you what percent of the parent function's time was spent in this function (and the body vs. other function calls). For instance, if main called function_1 and function_2, function_2 calls function_3, and then main calls function_3: main (100%, 1% in function body): function_1 (9%, 9% in function body): function_2 (90%, 85% in function body): function_3 (100%, 100% in function body) function_3 (1%, 1% in function body) I would see this and think, "Something is taking a long time in the code in the body of function_2. If I want my program to be faster, that's where I should start." Does anyone know how I can most easily get this exact profiling output for a python program? I've seen people say to do this: import cProfile, pstats prof = cProfile.Profile() prof = prof.runctx("real_main(argv)", globals(), locals()) stats = pstats.Stats(prof) stats.sort_stats("time") # Or cumulative stats.print_stats(80) # 80 = how many to print but it's quite messy compared to that elegant call tree. Please let me know if you can easily do this, it would help quite a bit. Cheers!

  • adding mongo to path

    - by Mike
    Bit of a noob question. I have downloaded MongoDb and installed it here /Users/mike/downloads/mongodb In order to start it, I then have to 'cd' into the 'bin' /Users/mike/downloads/mongodb/bin and run ./mongod (to start the database) and ./mongo (to start the mongo shell) The problem is that I can only work with python and ruby scripts using the mongo shell if I have those scripts stored in the same bin directory, and I don't think that's the ideal set up. Will exporting the path allow me to access mongo from outside the bin? For example, I would prefer to have my ruby scripts in /sites/ruby and be able to access mongo by starting ruby in /sites/ruby. If exporting to path is the solution, how do I do that. I'm using a mac

  • ifconfig : Command 'ifconfig' is available in '/sbin/ifconfig'

    - by Sahil Grover
    My question is related to another open question. My echo $PATH gives me an output which is like /home/sahil/.rvm/gems/ruby-1.9.3-p125/bin:/home/sahil/.rvm/gems/ruby-1.9.3-p125@global/bin:/home/sahil/.rvm/rubies/ruby-1.9.3-p125/bin:/home/sahil/.rvm/bin:/usr/local/bin:/usr/bin:/bin:/usr/games:/home/sahil/.rvm/bin{}:/home/android-sdks/{}:/home/android-sdks/platform-tools/{}:/home/android-sdks/tools/{}:/home/sahil/android-sdks/tools{}:/home/sahil/android-sdks/tools:/home/sahil/android-sdks/platform-tools/ But running ifconfig gives me an output like Command 'ifconfig' is available in '/sbin/ifconfig' The command could not be located because '/sbin' is not included in the PATH environment variable. This is most likely caused by the lack of administrative privileges associated with your user account. ifconfig: command not found after running command like given in other question export PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" it runs ifconfig but blocks other commands of ruby rails or rvm. Seeking help how to resolve this. Also why this happens?

  • Community Branching

    - by Dane Morgridge
    As some may have noticed, I have taken a liking to Ruby (and Rails in particular) quite a bit recently. This last weekend I spoke at the NYC Code Camp on a comparison of ASP.NET and Rails as well as an intro to Entity Framework talk.  I am speaking at RubyNation in April and have submitted to other ruby conferences around the area and I am also doing a Rails and MongoDB talk at the Philly Code Camp in April. Before you start to think this is my "I'm leaving .NET post", which it isn't so I need to clarify. I am not, nor do I intend to any time in the near future plan on abandoning .NET.  I am simply branching out into another community based on a development technology that I very much enjoy.  If you look at my twitter bio, you will see that I am into Entity Framework, Ruby on Rails, C++ and ASP.NET MVC, and not necessarily in that order.  I know you're probably thinking to your self that I am crazy, which is probably true on several levels (especially the C++ part). I was actually crazy enough at the NYC Code Camp to show up wearing a Linux t-shirt, presenting with my MacBook Pro on Entity Framework, ASP.NET MVC and Rails. (I did get pelted in the head with candy by Rachel Appel for it though) At all of the code camps I am submitting to this year, i will be submitting sessions on likely all four topics, and some sessions will be a combination of 2 or more.  For example, my "ASP.NET MVC: A Gateway To Rails?" talk touches ASP.NET MVC, Entity Framework Code First and Rails. Simply put (and I talk about this in my MVC & Rails talk) is that learning and using Rails has made me a better ASP.NET MVC developer. Just one example of this is helper methods.  When I started working with ASP.NET MVC, I didn't really want to use helpers and preferred to just use standard html tags, especially where links were concerned.  It was just me being stubborn and not really seeing all of the benefit of the helpers.  To my defense, coming from WebForms, I wanted to be as bare metal as possible and it seemed at first like a lot of the helpers were an unnecessary abstraction. I took my first look at Rails back in v1 and didn't spend very much time with it so I dismissed it and went on my merry ASP.NET WebForms way.  Then I picked up ASP.NET MVC and grasped the MVC pattern itself much better. After this, I took another look at Rails and everything made sense.  I decided then to learn Rails. (I think it is important for developers to learn new languages and platforms regularly so it was a natural progression for me) I wanted to learn it the right way, so when I dug into code, everyone used helpers everywhere for pretty much everything possible. I took some time to dig in and found out how helpful they were and subsequently realized how awesome they were in ASP.NET MVC also and started using them. In short, I love Rails (and Ruby in general).  I also love ASP.NET MVC and Entity Framework and yes I still love C++.  I have varying degrees of love for them individually at any given moment and it is likely to shift based on the current project I am working on.  I know you're thinking it so before you ask the question. "Which do I use when?", I'm going to give the standard developer answer of: It depends.  There are a lot of factors that I am not going to even go into that would go into a decision.  The most basic question I would ask though is,  does this project depend on .NET?  If it does, then I'd say that ASP.NET MVC is probably going to be the more logical choice and I am going to leave it at that.  I am working on projects right now in both technologies and I don't see that changing anytime soon (one project even uses both). With all that being said, you'll find me at code camps, conferences and user groups presenting on .NET, Ruby or both, writing about .NET and Ruby and I will likely be blogging on both in the future.  I know of others that have successfully branched out to other communities and with any luck I'll be successful at it too. On a (sorta) side note, I read a post by Justin Etheredge the other day that pretty much sums up my feelings about Ruby as a language.  I highly recommend checking it out: What Is So Great About Ruby?

  • Can I list file names (or their parent directories) that were recently deleted using rm in OS X?

    - by Andrew Grimm
    Is it possible to find out which files and directories have recently been deleted by rm in OS X? Or failing that, is it possible to find which parent directories have had files or directories within it deleted? The OS version is Snow Leopard. Background: Last night, rvm (ruby version manager) did rm -rf of the ~/ruby directory from the home directory. (This bug has since been fixed) Ideally, I'd like to know what files within the ~/ruby directory were deleted, but failing that, I'd like to know if rvm deleted anything outside of ~/ruby . In case anyone's wondering about backups...: Just about everything within ~/ruby is a git project that has a remote repo, and I have a fairly recent Time Machine backup (only 20 days old).
