How should a one-man development shop document their code?

- by CKoenig

Hi, please let me first describe my situation. I work in an IT department for a small-to-medium sized industrial-company and basically I'm the only real developer (sometimes a second guy joins in for his own projects). I programm mostly in C#/.net. Of course I only programm for internal need (Intranet, reporting, data-driven apps, some mobile apps, ...). My question is how should I document my work? It's a highly dynamic environment (the features and bug fixes I implement are tested by me during production, and go live, often within a day. If I technical documentation like MSDN or even overview diagramms those would take me more time to sync than the whole programming process. Also I feel it's a waste of time because I would be the only one who ever read it. I do understand that if I get sick, leave, or forget this documentation would be valuable. PS:well of course you are right - the quesion is how much and how/where. I try using the XML-docu comments for the public exposed parts but as I'm a believer in self-documenting code the comments mostly restates in plain text what you can read from the method-head itself :(Maybe using the remarks section is the key but if you have 30 lines of code with a 15 line xml-comment in front it just looks dirty (sorry for posting it here but our firewall rejects JSON :( )

uninitialized constant Test::Unit::TestResult::TestResultFailureSupport

- by Vitaly Kushner

I get the error in subj when I'm trying to run specs or generators in a fresh rails project. This happens when I add shoulda to the mix. I added the following in the config/environment.rb: config.gem 'rspec', :version => '1.2.6', :lib => false config.gem 'rspec-rails', :version => '1.2.6', :lib => false config.gem "thoughtbot-shoulda", :version => "2.10.2", :lib => 'shoulda', :source => "http://gems.github.com" I'm on OSX. ruby 1.8.6 (2008-08-11 patchlevel 287) gems 1.3.5 rails 2.3.4 rspec - 1.2.6 shoulda - 2.10.2 test-unit - 2.0.3 I'm aware of this and adding config.gem 'test-unit', :lib => 'test/unit' indeed solves the genrator problem as it doesn't throw an exception, but it prints 0 tests, 0 assertions, 0 failures, 0 errors, 0 pendings, 0 omissions, 0 notifications at the end of the run so I suppose it tries to run tests which is unexpected and undesired, also the specs stop to run at all, seems like rspec is not running at all, when running rake spec I get the test-unit output again (with 0 tests as there are only specs, no tests defined)

ruby on rails: undefined method "version_requirements' when attempting to start server after new install

- by ezabak

Hi there, I had to newly install ruby on rails recently. When I attempted to start the server for a project I had already been working on previous to this new install, I received the following error: $ ruby script/server => Booting WEBrick... ./script/../config/../vendor/rails/railties/lib/rails/gem_dependency.rb:107:in `requirement': undefined method `version_requirements' for #<Gem::Dependency:0xb74bf764> (NoMethodError) from ./script/../config/../vendor/rails/railties/lib/initializer.rb:292:in `check_gem_dependencies' from ./script/../config/../vendor/rails/railties/lib/initializer.rb:292:in `map' from ./script/../config/../vendor/rails/railties/lib/initializer.rb:292:in `check_gem_dependencies' from ./script/../config/../vendor/rails/railties/lib/initializer.rb:165:in `process' from ./script/../config/../vendor/rails/railties/lib/initializer.rb:112:in `send' from ./script/../config/../vendor/rails/railties/lib/initializer.rb:112:in `run' from /media/78C0-455B/bidmc/schedule/config/environment.rb:13 from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require' from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' from /media/78C0-455B/bidmc/schedule/vendor/rails/activesupport/lib/active_support/dependencies.rb:153:in `require' from /media/78C0-455B/bidmc/schedule/vendor/rails/activesupport/lib/active_support/dependencies.rb:521:in `new_constants_in' from /media/78C0-455B/bidmc/schedule/vendor/rails/activesupport/lib/active_support/dependencies.rb:153:in `require' from /media/78C0-455B/bidmc/schedule/vendor/rails/railties/lib/commands/servers/webrick.rb:59 from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require' from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' from /media/78C0-455B/bidmc/schedule/vendor/rails/activesupport/lib/active_support/dependencies.rb:153:in `require' from /media/78C0-455B/bidmc/schedule/vendor/rails/activesupport/lib/active_support/dependencies.rb:521:in `new_constants_in' from /media/78C0-455B/bidmc/schedule/vendor/rails/activesupport/lib/active_support/dependencies.rb:153:in `require' from /media/78C0-455B/bidmc/schedule/vendor/rails/railties/lib/commands/server.rb:49 from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require' from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' from script/server:3 I have the latest versions of ruby, rubygems, and rails.

Starting with versioning mysql schemata without overkill. Good solutions?

- by tharkun

I've arrived at the point where I realise that I must start versioning my database schemata and changes. I consequently read the existing posts on SO about that topic but I'm not sure how to proceed. I'm basically a one man company and not long ago I didn't even use version control for my code. I'm on a windows environment, using Aptana (IDE) and SVN (with Tortoise). I work on PHP/mysql projects. What's a efficient and sufficient (no overkill) way to version my database schemata? I do have a freelancer or two in some projects but I don't expect a lot of branching and merging going on. So basically I would like to keep track of concurrent schemata to my code revisions. [edit] Momentary solution: for the moment I decided I will just make a schema dump plus one with the necessary initial data whenever I'm going to commit a tag (stable version). That seems to be just enough for me at the current stage.[/edit] [edit2]plus I'm now also using a third file called increments.sql where I put all the changes with dates, etc. to make it easy to trace the change history in one file. from time to time I integrate the changes into the two other files and empty the increments.sql[/edit]

Why is there unreachable code here?

- by Richard

I am writing a c# app and want to output error messages to either the console or a messagebox (Depending on the app type: enum AppTypeChoice { Console, Windows } ), and also control wether the app keeps running or not ( bool StopOnError ). I came up with this method that will check all the criteria, but I'm getting an "unreachable code detected" warning. I can't see why! Here is the whole method (Brace yourselves for some hobbyist code!) public void OutputError(string message) { string standardMessage = "Something went WRONG!. [ But I'm not telling you what! ]"; string defaultMsgBoxTitle = "Aaaaarrrggggggggggg!!!!!"; string dosBoxOutput = "\n\n*** " + defaultMsgBoxTitle + " *** \n\n Message was: '" + message + "'\n\n"; AppTypeChoice appType = DataDefs.AppType; DebugLevelChoice level = DataDefs.DebugLevel; // Decide how much info we should give out here... if (level != DebugLevelChoice.None) { // Give some info.... if (appType == AppTypeChoice.Windows) MessageBox.Show(message, defaultMsgBoxTitle, MessageBoxButtons.OK, MessageBoxIcon.Error); else Console.WriteLine(dosBoxOutput); } else { // Be very secretive... if (appType == AppTypeChoice.Windows) MessageBox.Show(standardMessage, defaultMsgBoxTitle, MessageBoxButtons.OK, MessageBoxIcon.Error); else Console.WriteLine(standardMessage); } // Decide if app falls over or not.. if (DataDefs.StopOnError == true) Environment.Exit(0); // UNREACHABLE CODE HERE } Also, while I have your attention, to get the app type, I'm just using a constant at the top of the file (ie. AppTypeChoice.Console in a Console app etc) - is there a better way of doing this (i mean finding out in code if it is a DOS or Windows app)? Also, I noticed that I can use a messagebox with a fully-qualified path in a Console app...How bad is is to do that ( I mean, will I get tarred and feathered when other developers see it?!) Thanks for your help

Migrating MOSS 2007 from SQL 2000 to SQL 2005 - Addendum

- by lunacrescens

This is a continuation of an earlier question I had about moving the databases for a MOSS 2007 installation from SQL 2000 to SQL 2005. Here's the URL for the original question: http://stackoverflow.com/questions/254517/migrating-moss-2007-from-sql-2000-to-sql-2005 In my test environment, I've successfully moved the databases to the SQL 2005 test machine and things appear to be working fine. But, on the "Servers in Farm" page of the Central Admin | Operations, it still shows the old (i.e. SQL 2000) server as the Configuration Database Server. Also, it shows the old config database as being the Configuration Database. I know that the SQL2000 server and old config database (that are showing on this page) are NOT being used, because we've deactived the SQL instance in SQL2000. I've tried "removing" the server, and get a message about "Uninstalling SharePoint products and technologies" being the better route. So, I disconnected from the test databases, uninstalled SharePoint from the test WFE server, and reinstalled it. That didn't do anything. Before uninstalling/reinstalling I also tried simply rerunning the SharePoint Configuration wizard, and that didn't do anything either. Does anyone know how to update the Config Server and Config Database on the "Servers in Farm" page after having moved the Config and Content DBs? Is there something I'm missing or overlooking? Thanks.

How to move/drag multiple images with CALayer???

- by gbf.sara

I have more than 10 images in screen and i want to move each image using CALayer concept. While am trying to move first image,its working. Even when i drag my second image also, its working. But after that when i get back to first image and when i try to move , am struck up. its not working. I dono where it went wrong. Here's ma code //Assigning Layer to UIImage// layer = [CALayer layer]; UIImage *image1 = [UIImage imageNamed:[NSString stringWithFormat:@"%@_thumb.png",[tiv imageName]]]; layer.contents = (id)image1.CGImage; layer.position=CGPointMake(200,200); layer.frame = CGRectMake(110, 180, 100, 100); [self.view.layer addSublayer:layer]; [layer needsDisplay]; [self.view.layer needsDisplay]; [layer needsLayout]; //Here i try to move my image// - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesMoved:touches withEvent:event]; NSArray *allTouches = [touches allObjects]; int count = [allTouches count]; if (count == 1) { if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:0] locationInView:self.view])) { layer.position = [[allTouches objectAtIndex:0] locationInView:self.view]; return; } } if (count > 1) { if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:-1] locationInView:self.view])) { layer.position = [[allTouches objectAtIndex:0] locationInView:self.view]; return; } } } Also ive planned to use single CALayer for multiple images.. When i click an image, it should be placed in that CALayer and when i click another, the same CALayer should take the latter one. So tat whenever i drag an image it should move(no matter how many images r there) . Do u think this concept will work out or is there any other idea??? My concept may seems to be a basic one. Am new to this environment n so kindly help me..

Ruby script/console and Ruby script/server using two different DBs?

- by aronchick

Has anyone seen where script/console and script/server load two different databases (though both report using the same)? Here's the first output $ script/server => Booting WEBrick => Rails 2.3.5 application starting on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server [2010-03-21 15:54:05] INFO WEBrick 1.3.1 [2010-03-21 15:54:05] INFO ruby 1.8.7 (2010-01-10) [i386-mingw32] [2010-03-21 15:54:05] INFO WEBrick::HTTPServer#start: pid=7148 port=3000 No errors. I then run my standard code for entering a form - no problems. Checking the Dev Database (.yml at bottom): mysql> select * from books; [...] | 712 | Book | Book Name | 2010-03-21 22:29:22 | 2010-03-21 22:29:22 | [...] 712 rows in set (0.00 sec) The code CLEARLY saved it seconds ago And now here's the output of script/console: $ script/console Loading development environment (Rails 2.3.5) >> Books.all => [] Nothing. Further, upon further inspection, it's using the production database, but I can't figure out why. Any thoughts here? All consoles have been closed and reopened.

How do I fix this installation problem with multicore Solr on Ubuntu 10.04?

- by coleifer

Following instructions from the two sites below, I've installed Tomcat 6 and Solr 1.4. http://gist.github.com/204638 https://wiki.fourkitchens.com/display/TECH/Solr+1.4+on+Ubuntu+9.10+and+CentOS+5 I have successfully got it up and running on a server running 9.04 with multicore support, but on the 10.04 I can't seem to get it to work. I am able to reach localhost:xxxx/solr/ on the 10.04 box and see a single link to the Solr Admin, but following the link takes me to a 404 page with the following output: /solr/admin/ HTTP Status 404 - missing core name in path The requested resource (missing core name in path) is not available I am also unable to access /solr/site1/ as I would except - it similarly returns a 404.  <cores adminPath="/admin/cores"> <core name="site1" instanceDir="site1" /> <core name="site2" instanceDir="site2" /> </cores>  <Context docBase="/var/solr/solr.war" debug="0" privileged="true" allowLinking="true" crossContext="true"> <Environment name="solr/home" type="java.lang.String" value="/var/solr" override="true" /> </Context>

Change select's class based on selected option's class

- by Alasdair

I have a page that contains numerous <select> elements. What I'm trying to achieve is to ensure that if a <select>'s selected <option> has a class called italic, then the <select> then has the italic class added (i.e. jQuery.addClass('italic')). If it doesn't, then the italic class is removed from the <select> to ensure other <option> elements are displayed correctly (i.e. jQuery.removeClass('italic')). What I'm noticing with most of my attempts is that either all the <select> have the italic class or that the italic class isn't being removed accordingly. Since I'm unsure my choice in selectors and callback logic are particularly sound or good practice in this instance (as I've been frustratingly trying to make it work) I've decided not to include the code I used in previous attempts. Instead, refer to this small HTML & CSS example: .italic { font-style: italic; } <select id="foo" name="foo" size="1" <option value="NA" selected="selected" - Select - </option <option value="1"Bar</option <option value="2"Fu</option <option value="3"Baz</option </select Also, I am aware that not all browsers support CSS styling of <select> and <option>. The related J2EE web application will only ever be accessed via Firefox under a controlled environment.

Cannot upload media via Wordpress uploader

- by Justin Johnson

This has to do with media uploading in Wordpress. Every time WP creates a folder for new uploads (it organizes uploads by year and month: yyyy/mm), it creates it with the "apache:apache' user and group, with full access to all (777 or drwxrwxrwx). However, after that, WP cannot create a folder within that folder (e.g.: mkdir 2011 succeeds, but mkdir 2011/01 fails). Also, uploads cannot be moved into these newly created folders even though the permissions are 777 (rwxrwxrwx). Once a month, I have to chown the newly created folders to be the same as user:group as the rest of the files. Once I do that, uploading works fine (which doesn't make sense to me The really frustrating part is that this problem doesn't exist in other WP installs on other domains on the same server. * I wasn't sure if this should be here or on serverfault. Edit: The containing directory /.../httpdocs/blog/wp-content/uploads has the correct ownership drwxrwxrwx 5 myuser psaserv 4096 Jun 3 18:38 uploads This is a Plesk/CentOS environment hosted by Media Temple (dv). I've written the following test script to simulate the problem <pre><?php $d = "d" . mt_rand(100, 500); var_dump( get_current_user(), $d, mkdir($d), chmod($d, 0777), mkdir("$d/$d"), chmod("$d/$d", 0777), fileowner($d), getmyuid() ); The script always creates the first directory mkdir($d) successfully. On domain A, where the WP problem is, it cannot create the nested directory mkdir("$d/$d"). However, on domain B, both directories are successfully created. I am running each script at /var/www/vhosts/domainA/httpdocs/tmp/t.php and /var/www/vhosts/domainB/httpdocs/tmp/t.php respectively I checked the permissions on tmp, httpdocs, and domain[AB] and they are the same for each path. The only thing that differs is the user.

MongoDB - proper use of collections?

- by zmg

In Mongo my understanding is that you can have databases and collections. I'm working on a social-type app that will have blogs and comments (among other things) and had previously be using MySQL and pretty heavy partitioning in an attempt to limit possible concurrency issues. With MySQL I've stuffed all my user data into a _user database with several tables to further partition the data (blogs, pages, etc). My immediate reaction with Mongo would be to create a 'users' database with one collection per user. In this way user 'zach' blog entries would go into the 'zach' collection with associated comments and such becoming sub-objects in the same collection. Basically like dynamically creating one table per user in MySQL, but apparently without the complexity and limitations that might impose. Of course since I haven't really used Mongo before I'm having trouble gauging the (ahem..) quality of this idea and the potential problems it might cause down the road. I'd like user data to be treated a lot like a users directory in a *nix environment where user created/non-shared (mostly) gets put into one place (currently with MySQL that would be the appname_users as mentioned above). Most of the users data will be specific to the users page(s). Some of the user data which is queried across all site users (searchable user profiles) is currently kept in a separate database/table and I expect things like this could be put into a appname_system database and be broken up into collections and/or application specific databases (appname_profiles). Anyway, since the available documentation on this is currently a little thin and my experience is extremely limited I thought I might find a little guidance from someone with a better working understanding of the system. On the plus side I'd really already been attempting to treat MySQL as a schema-less document-store and doing this with Mongo seems much more intuitive/sane/rational so I'm really looking forward to getting started. Thanks, Zach

How to organize integrity tests and code unit tests?

- by karlthorwald

I have several files with code testing code (which uses a "unittest" class). Later I found it would be nice to test database integrity also. I put this into a separate directory tree. (Things like the keys have correct format, parent and child nodes are pointing correctly and such.) I use the same unittest class for the integrity tests. Now I wonder if it makes really sense to keep this separate. To test the integrity of data I often duplicate parts of code that I use to test the code that handles the data. But it is not the same. The code tests use test databases (that get deleted after each test) and the integrity tests connect to the live data and analyze it. The integrity tests I want to call from cron and send an alarm if something happens in the live database. How would you handle that? Are there standards for such a setup? What is your experience? My tendency is to put everything in the same file, which would result in the code tests also being executed by the cron on the production environment.

ColdFusion blank page in IE7 on refresh?

- by richardtallent

I'm new to ColdFusion, have a very basic problem that's really slowing me down. I'm making edits in a text editor and refreshing the page in web browsers for testing. Standard web dev stuff, no browser-sniffing, redirection, or other weirdness, and no proxies involved. When I refresh the page in Chrome or Firefox, everything works fine, but when I refresh in IE7, I get a blank page. View Source shows me: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=utf-8"></HEAD> <BODY></BODY></HTML> That's it. While I am rendering to the transitional DTD, the real head contains a title, etc. My development server is CF 9, production is 8. This problem has been happening in both. Seems it may only be happening on pages that are the the result of a POST action. I've never experienced this in ASP.NET (my usual development environment) using the same browsers.

Retrieving dll version info via Win32 - VerQueryValue(...) crashes under Win7 x64

- by user256890

The respected open source .NET wrapper implementation (SharpBITS) of Windows BITS services fails identifying the underlying BITS version under Win7 x64. Here is the source code that fails. NativeMethods are native Win32 calls wrapped by .NET methods and decorated via DllImport attribute. private static BitsVersion GetBitsVersion() { try { string fileName = Path.Combine( System.Environment.SystemDirectory, "qmgr.dll"); int handle = 0; int size = NativeMethods.GetFileVersionInfoSize(fileName, out handle); if (size == 0) return BitsVersion.Bits0_0; byte[] buffer = new byte[size]; if (!NativeMethods.GetFileVersionInfo(fileName, handle, size, buffer)) { return BitsVersion.Bits0_0; } IntPtr subBlock = IntPtr.Zero; uint len = 0; if (!NativeMethods.VerQueryValue(buffer, @"\VarFileInfo\Translation", out subBlock, out len)) { return BitsVersion.Bits0_0; } int block1 = Marshal.ReadInt16(subBlock); int block2 = Marshal.ReadInt16((IntPtr)((int)subBlock + 2 )); string spv = string.Format( @"\StringFileInfo\{0:X4}{1:X4}\ProductVersion", block1, block2); string versionInfo; if (!NativeMethods.VerQueryValue(buffer, spv, out versionInfo, out len)) { return BitsVersion.Bits0_0; } ... The implementation follows the MSDN instructions by the letter. Still during the second VerQueryValue(...) call, the application crashes and kills the debug session without hesitation. Just a little more debug info right before the crash: spv = "\StringFileInfo\040904B0\ProductVersion" buffer = byte[1900] - full with binary data block1 = 1033 block2 = 1200 I looked at the targeted "C:\Windows\System32\qmgr.dll" file (The implementation of BITS) via Windows. It says that the Product Version is 7.5.7600.16385. Instead of crashing, this value should return in the verionInfo string. Any advice?

Register and Resolve Generic Interfaces Unity

- by user1643791

I am trying to register some generic interfaces and resolve them . I have the registering function private static void RegisterFolderAssemblies(Type t,string folder) { var scanner = new FolderGenericInterfaceScanner(); var scanned = scanner.Scan(t,folder); // gets the implementations from a specific folder scanned.ForEach(concrete => { if (concrete.BaseType != null || concrete.IsGenericType) { myContainer.RegisterType(t, Type.GetType(concrete.AssemblyQualifiedName), concrete.AssemblyQualifiedName); } }); } which is called by the bootstrapper with RegisterFolderAssemblies(typeof(IConfigurationVerification<>),Environment.CurrentDirectory); The registration seem to go through ok but when I try to Resolve them with Type generic = typeof(IConfigurationVerification<>); Type specific = generic.MakeGenericType(input.Arguments[0].GetType()); var verifications = BootStrap.ResolveAll(specific); The input.Arguments[0] is an object of the type the generic is implemented in I also tried using typeof(IConfigurationVerification<) instead and get the same error . When ResolveAll is public static List<object> ResolveAll(Type t) { return myContainer.ResolveAll(t).ToList(); } I get a ResolutionFailedException with them message "The current type, Infrastructure.Interfaces.IConfigurationVerification`1[Infrastructure.Configuration.IMLogPlayerConfiguration+LoadDefinitions], is an interface and cannot be constructed. Are you missing a type mapping?" Any help will be great. Thanks in advance

Rubygems on Debian: Gems won't load (LoadError)

I've installed the development version of Crunchbang, a linux distro based off Debian. I got Ruby and Rubygems installed, but I can't get the gems I've installed to load. Here is a command-line session: $ ruby -v ruby 1.9.1p378 (2010-01-10 revision 26273) [i486-linux] $ gem env RubyGems Environment: - RUBYGEMS VERSION: 1.3.6 - RUBY VERSION: 1.9.1 (2010-01-10 patchlevel 378) [i486-linux] - INSTALLATION DIRECTORY: /usr/lib/ruby1.9.1/gems/1.9.1 - RUBY EXECUTABLE: /usr/bin/ruby1.9.1 - EXECUTABLE DIRECTORY: /usr/bin - RUBYGEMS PLATFORMS: - ruby - x86-linux - GEM PATHS: - /usr/lib/ruby1.9.1/gems/1.9.1 - /home/corey/.gem/ruby/1.9.1 - GEM CONFIGURATION: - :update_sources => true - :verbose => true - :benchmark => false - :backtrace => false - :bulk_threshold => 1000 - REMOTE SOURCES: - http://rubygems.org/ $ echo $PATH /home/corey/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games:/home/corey/.gem/ruby/1.9.1:/usr/lib/ruby1.9.1/gems/1.9.1 $ gem list -d nokogiri `*** LOCAL GEMS ***` nokogiri (1.4.1) Authors: Aaron Patterson, Mike Dalessio Rubyforge: http://rubyforge.org/projects/nokogiri Homepage: http://nokogiri.org Installed at: /usr/lib/ruby1.9.1/gems/1.9.1 Nokogiri (?) is an HTML, XML, SAX, and Reader parser $ ruby -r rubygems -e "require 'nokogiri'" -e:1:in `require': no such file to load -- nokogiri (LoadError) from -e:1:in `' I've encountered similar problems on Ubuntu before, but they were easy to fix. I can't figure out what's wrong in this particular case, and Google didn't seem to know either. Any help would be greatly appreciated! By the way... this is my first submission to stackoverflow. I hope this question is relevant. :)

What should be the "trunk" development, or release

- by Nix

I have the unfortunate opportunity of source control via Borland's StarTeam. It unfortunately does very few things well, and one supreme weakness is its view management. I love SVN and come from an SVN mindset. Our issue is post production release we are spending countless hours merging changes into a "production support" environment. Please do not harass me this was not my doing, I inherited it and am trying to present a better way of managing the repository. It is not an option to switch to a different SCM tool. Current setup Product.1.0 (TRUNK, current production code, and at this level are pending bug fixes) Product.2.0(true trunk anything checked in gets tested, and then released next production cycle, a lot of changes occur in this view) My proposal is going to be to swap them, have all development be done on the trunk (Production), tag on releases, and as needed create child views to represent production support bug fixes. Production Production.2.0.SP.1 I can not find any documentation to support the above proposal so I am trying to get feedback on whether or not the change is a good idea and if there is anything you would recommend doing differently.

How/when to hire new programmers, and how to integrate them?

- by Shaul

Hiring new programmers, especially in a small company, can often present a Catch-22 situation. We have too much work to do, so we need to hire new programmers. But we can't hire new programmers now, because they will need mentoring and several months of learning curve in your industry/product/environment before they're useful, and none of the programmers has time to be a mentor to a new programmer, because they're all completely swamped with the current work load. That may be a slightly frivolous way of describing the situation, but nevertheless, it's difficult for a small company on a tight budget to justify hiring someone who is not only going to be unproductive for a long time, but will also take away from the performance of the current programmers. How have you dealt with this kind of situation? When is the best time to hire someone? What are the best tasks to assign to a new team member so that they can learn their way around your code base and start getting their hands dirty as quickly as possible? How do you get the new guy useful without bogging your existing programmers down in too much mentoring? Any comments & suggestions you have are much appreciated!

rake task via cron problem loading rubygems

- by Matenia Rossides

I have managed to get a cron job to run a rake task by doing the following: cd /home/myusername/approotlocation/ && /usr/bin/rake sendnewsletter RAILS_ENV=development i have checked with which ruby and which rake to make sure the paths are correct (from bash) the job looks like it wants to run as i get the following email from the cron daemon when it completes Missing these required gems: chronic whenever searchlogic adzap-ar_mailer twitter gdata bitly ruby-recaptcha You're running: ruby 1.8.7.22 at /usr/bin/ruby rubygems 1.3.5 at /home/myusername/gems, /usr/lib/ruby/gems/1.8 Run `rake gems:install` to install the missing gems. (in /home/myusername/approotlocation) my custom rake file within lib/tasks is as follows: task :sendnewsletter => :environment do require 'rubygems' require 'chronic' require 'whenever' require 'searchlogic' require 'adzap-ar_mailer' require 'twitter' require 'gdata' require 'bitly' require 'ruby-recaptcha' @recipients = Subscription.all(:conditions => {:active => true}) for user in @recipients Email.send_later(:deliver_send_newsletter,user) end end with or without the require items, it still gives me the same error ... can anyone shed some light on this? or alternatively advise me on how to make a custom file within the script directory that will run this function (I already have a cron job working that will run and process all my delayed_jobs. Cheers!

How to organize live data integrity tests and code unit tests?

- by karlthorwald

I have several files with code testing code (which uses a "unittest" class). Later I found it would be nice to test database integrity also. I put this into a separate directory tree. (Things like the keys have correct format, parent and child nodes are pointing correctly and such.) I use the same unittest class for the integrity tests. Now I wonder if it makes really sense to keep this separate. To test the integrity of data I often duplicate parts of code that I use to test the code that handles the data. But it is not the same. The code tests use test databases (that get deleted after each test) and the integrity tests connect to the live data and analyze it. The integrity tests I want to call from cron and send an alarm if something happens in the live database. How would you handle that? Are there standards for such a setup? What is your experience? My tendency is to put everything in the same file, which would result in the code tests also being executed by the cron on the production environment.

Run a PHP script every second using CLI

- by Saif Bechan

Hello, I have a dedicated server running Cent OS with a Parallel PLESK panel. I need to run a php script every second, that updates my database. These is no alternative way timewise, i have checked every method, it needs to be updated every second. I can find my script using the url: http://www.mysite.com/phpfile.php?key=123, and this has to be executed every second. Does anyone have any knowledge at all on doing this, i can not seem to find the answer. I heard about doing it with CLI and putty, but i have no knowledge of this at all. Or can this be done using the PLESK Panel? And can the file be executed locally every second. Like \phpfile.php If someone helps me on answering these question i would really appreciate it. Regards EDIT It has been a few months since i added this question. I ended up using the following code: #!/user/bin/php $start = microtime(true); set_time_limit(60); for (i = 0; i < 59; ++$i) { doMyThings(); time_sleep_until($start + $i + 1); } Thank you for this code guys! My cronjob is set to every minute. I have been running this for some time now in a test environment, and this works out great. It works really supperfast, and i see no increase in CPU nor Memory usage.

Anything speaking against the bitnami.org Ruby/Rails/Redmine Stack?

- by Pekka

I am looking to set up a Redmine server on a Windows virtual machine on my local workstation. (Background in this related question.) I have zero knowledge of Ruby nor Rails, and while Redmine may be the opportunity to dip into those platforms somewhat, my first goal is to get it running as quickly and easily as possible. For that, I am eyeing the Bitnami Redmine Package. It promises point-and-click install, and a self-contained environment with everything you need. Apart from the learning factor, are there any serious limitations this method implies? Any serious cutdowns in customizability? I will be wanting to customize the template right away, for example, and install plugins. The package looks o.k. to me but before I install it, I was curious to know whether anybody would advise against it and why. Edit: The first impression is great. From 0 to a working Redmine installation in twelve minutes! Wow.
