• Neo4j Windows Plugin Installation desktop V2.M06

  - by user2904850

  I have downloaded and installed the latest Window V2 Community M06 build of Neo4j on a windows 7 64 bit machine (I have tried the 32bit and 64 bit installs). Installation proceeds without and problems and the system runs normally but there is no /plugins directory (on both versions):- \Program Files (x86)\Neo4j Community\ \Program Files (x86)\Neo4j Community\.install4j \Program Files (x86)\Neo4j Community\bin I am trying to install the Spatial plugin .. so I tried creating the \plugins directory. I extracted the zip file and left the zip file in the directory but the plugins are not found:- C:\Users\WFN44217>curl localhost:7474/db/data/ { "extensions" : { }, "node" : "http://localhost:7474/db/data/node", "reference_node" : "http://localhost:7474/db/data/node/0", "node_index" : "http://localhost:7474/db/data/index/node", "relationship_index" : "http://localhost:7474/db/data/index/relationship", "extensions_info" : "http://localhost:7474/db/data/ext", "relationship_types" : "http://localhost:7474/db/data/relationship/types", "batch" : "http://localhost:7474/db/data/batch", "cypher" : "http://localhost:7474/db/data/cypher", "transaction" : "http://localhost:7474/db/data/transaction", "neo4j_version" : "2.0.0-M06" } I have tried some other plugins, but these are also not found. Any idea what might be missing?

• At times, you need to hire a professional.

  - by Phil Factor

  After months of increasingly demanding toil, the development team I belonged to was told that the project was to be canned and the whole team would be fired.  I’d been brought into the team as an expert in the data implications of a business re-engineering of a major financial institution. Nowadays, you’d call me a data architect, I suppose.  I’d spent a happy year being paid consultancy fees solving a succession of interesting problems until the point when the company lost is nerve, and closed the entire initiative. The IT industry was in one of its characteristic mood-swings downwards.  After the announcement, we met in the canteen. A few developers had scented the smell of death around the project already hand had been applying unsuccessfully for jobs. There was a sense of doom in the mass of dishevelled and bleary-eyed developers. After giving vent to anger and despair, talk turned to getting new employment. It was then that I perked up. I’m not an obvious choice to give advice on getting, or passing,  IT interviews. I reckon I’ve failed most of the job interviews I’ve ever attended. I once even failed an interview for a job I’d already been doing perfectly well for a year. The jobs I’ve got have mostly been from personal recommendation. Paradoxically though, from years as a manager trying to recruit good staff, I know a lot about what IT managers are looking for.  I gave an impassioned speech outlining the important factors in getting to an interview.  The most important thing, certainly in my time at work is the quality of the résumé or CV. I can’t even guess the huge number of CVs (résumés) I’ve read through, scanning for candidates worth interviewing.  Many IT Developers find it impossible to describe their  career succinctly on two sides of paper.  They leave chunks of their life out (were they in prison?), get immersed in detail, put in irrelevancies, describe what was going on at work rather than what they themselves did, exaggerate their importance, criticize their previous employers, aren’t  aware of the important aspects of a role to a potential employer, suffer from shyness and modesty,  and lack any sort of organized perspective of their work. There are many ways of failing to write a decent CV. Many developers suffer from the delusion that their worth can be recognized purely from the code that they write, and shy away from anything that seems like self-aggrandizement. No.  A resume must make a good impression, which means presenting the facts about yourself in a clear and positive way. You can’t do it yourself. Why not have your resume professionally written? A good professional CV Writer will know the qualities being looked for in a CV and interrogate you to winkle them out. Their job is to make order and sense out of a confused career, to summarize in one page a mass of detail that presents to any recruiter the information that’s wanted. To stand back and describe an accurate summary of your skills, and work-experiences dispassionately, without rancor, pity or modesty. You are no more capable of producing an objective documentation of your career than you are of taking your own appendix out.  My next recommendation was more controversial. This is to have a professional image overhaul, or makeover, followed by a professionally-taken photo portrait. I discovered this by accident. It is normal for IT professionals to face impossible deadlines and long working hours by looking more and more like something that had recently blocked a sink. Whilst working in IT, and in a state of personal dishevelment, I’d been offered the role in a high-powered amateur production of an old ex- Broadway show, purely for my singing voice. I was supposed to be the presentable star. When the production team saw me, the air was thick with tension and despair. I was dragged kicking and protesting through a succession of desperate grooming, scrubbing, dressing, dieting. I emerged feeling like “That jewelled mass of millinery, That oiled and curled Assyrian bull, Smelling of musk and of insolence.” (Tennyson Maud; A Monodrama (1855) Section v1 stanza 6) I was then photographed by a professional stage photographer.  When the photographs were delivered, I was amazed. It wasn’t me, but it looked somehow respectable, confident, trustworthy.   A while later, when the show had ended, I took the photos, and used them for work. They went with the CV to job applications. It did the trick better than I could ever imagine.  My views went down big with the developers. Old rivalries were put immediately to one side. We voted, with a show of hands, to devote our energies for the entire notice period to getting employable. We had a team sourcing the CV Writer,  a team organising the make-overs and photographer, and a third team arranging  mock interviews. A fourth team determined the best websites and agencies for recruitment, with the help of friends in the trade.  Because there were around thirty developers, we were in a good negotiating position.  Of the three CV Writers we found who lived locally, one proved exceptional. She was an ex-journalist with an eye to detail, and years of experience in manipulating language. We tried her skills out on a developer who seemed a hopeless case, and he was called to interview within a week.  I was surprised, too, how many companies were experts at image makeovers. Within the month, we all looked like those weird slick  people in the ‘Office-tagged’ stock photographs who stare keenly and interestedly at PowerPoint slides in sleek chromium-plated high-rise offices. The portraits we used still adorn the entries of many of my ex-colleagues in LinkedIn. After a months’ worth of mock interviews, and technical Q&A, our stutters, hesitations, evasions and periphrastic circumlocutions were all gone.  There is little more to relate. With the résumés or CVs, mugshots, and schooling in how to pass interviews, we’d all got new and better-paid jobs well  before our month’s notice was ended. Whilst normally, an IT team under the axe is a sad and depressed place to belong to, this wonderful group of people had proved the power of organized group action in turning the experience to advantage. It left us feeling slightly guilty that we were somehow cheating, but I guess we were merely leveling the playing-field.

• Missing a constant on load.. how can i get around this? (Rails::Plugin::OpenID)

  - by Chris Kimpton

  I have a Rails 2 project that I am trying to upgrade to Rails 3, but getting some issues with bundler. When I run "rake", it runs the tests just fine. But when I run "bundle exec rake" it fails to find a constant. The error is this: /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/dependencies.rb:131:in `const_missing': uninitialized constant Rails::Plugin::OpenID (NameError) from /Users/kimptoc/Documents/ruby/borisbikes/borisbikestats.pre3/vendor/plugins/open_id_authentication/init.rb:16:in `evaluate_init_rb' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:182:in `call' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:182:in `evaluate_method' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:166:in `call' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:90:in `run' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:90:in `each' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:90:in `send' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:90:in `run' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/activesupport-2.3.9/lib/active_support/callbacks.rb:276:in `run_callbacks' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/actionpack-2.3.9/lib/action_controller/dispatcher.rb:51:in `send' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/actionpack-2.3.9/lib/action_controller/dispatcher.rb:51:in `run_prepare_callbacks' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/rails-2.3.9/lib/initializer.rb:631:in `prepare_dispatcher' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/rails-2.3.9/lib/initializer.rb:185:in `process' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/rails-2.3.9/lib/initializer.rb:113:in `send' from /Users/kimptoc/.rvm/gems/ruby-1.8.7-p330@p-borisbikestats-pre-rails3/gems/rails-2.3.9/lib/initializer.rb:113:in `run' from /Users/kimptoc/Documents/ruby/borisbikes/borisbikestats.pre3/config/environment.rb:9 from ./test/test_helper.rb:2:in `require' from ./test/test_helper.rb:2 I have these gems installed: $ gem list *** LOCAL GEMS *** actionmailer (2.3.9) actionpack (2.3.9) activerecord (2.3.9) activeresource (2.3.9) activesupport (2.3.9) authlogic (2.1.3) bundler (1.0.7) gravtastic (2.2.0) linecache (0.43) mocha (0.9.10) newrelic_rpm (2.13.4) parseexcel (0.5.2) rack (1.1.0) rack-openid (1.1.1) rails (2.3.9) rake (0.8.7) ruby-debug-base (0.10.5.jb2, 0.10.4) ruby-debug-ide (0.4.15) ruby-openid (2.1.8, 2.1.7, 2.0.4) sqlite3-ruby (1.3.2) The bundler Gemfile is as follows: source 'http://rubygems.org' #gem 'rails', '3.0.3' gem "rails", "2.3.9" gem "activesupport", "2.3.9" gem "ruby-openid", "2.1.7", :require => "openid" #gem "authlogic-oid", "1.0.4" # Bundle edge Rails instead: # gem 'rails', :git => 'git://github.com/rails/rails.git' gem 'sqlite3-ruby', :require => 'sqlite3' gem "authlogic", "= 2.1.3" gem "newrelic_rpm" # gem "facebooker" gem "parseexcel" gem 'gravtastic', '= 2.2.0' gem "rack-openid", '=1.1.1', :require => 'rack/openid' # not sure what this does... gem "mocha" I have these plugins installed: 2dc_jqgrid authlogic_openid open_id_authentication squirrel I see these similar questions: Missing a constant on load.. how can i get around this? and Requiring gem in Rails 3 Controller failing with "Constant Missing" But their solutions dont seem to work for my situation. I am guessing the issue is around the plugins, but my ruby-foo is too weak. Thanks in advance, Chris

• ASP.NET MVC, Web API, Razor, e Open Source (Código Aberto)

  - by Leniel Macaferi

  A Microsoft tornou o código fonte da ASP.NET MVC disponível sob uma licença open source (de código aberto) desde a primeira versão V1. Nós também integramos uma série de grandes tecnologias de código aberto no produto, e agora entregamos jQuery, jQuery UI, jQuery Mobile, jQuery Validation, Modernizr.js, NuGet, Knockout.js e JSON.NET como parte integrante dos lançamentos da ASP.NET MVC. Estou muito animado para anunciar hoje que também iremos liberar o código fonte da ASP.NET Web API e ASP.NET Web Pages (também conhecido como Razor) sob uma licença open source (Apache 2.0), e que iremos aumentar a transparência do desenvolvimento de todos os três projetos hospedando seus repositórios de código no CodePlex (usando o novo suporte ao Git anunciado na semana passada - em Inglês). Isso permitirá um modelo de desenvolvimento mais aberto, onde toda a comunidade será capaz de participar e fornecer feedback nos checkins (envios de código), corrigir bugs, desenvolver novos recursos, e construir e testar os produtos diariamente usando a versão do código-fonte e testes mais atualizada possível. Nós também pela primeira vez permitiremos que os desenvolvedores de fora da Microsoft enviem correções e contribuições de código que a equipe de desenvolvimento da Microsoft irá rever para potencial inclusão nos produtos. Nós anunciamos uma abordagem de desenvolvimento semelhantemente aberta com o Windows Azure SDK em Dezembro passado, e achamos que essa abordagem é um ótimo caminho para estreitar as relações, pois permite um excelente ciclo de feedback com os desenvolvedores - e, finalmente, permite a entrega de produtos ainda melhores, como resultado. Muito importante - ASP.NET MVC, Web API e o Razor continuarão a ser totalmente produtos suportados pela Microsoft que são lançados tanto independentemente, bem como parte do Visual Studio (exatamente da mesma maneira como é feito hoje em dia). Eles também continuarão a ser desenvolvidos pelos mesmos desenvolvedores da Microsoft que os constroem hoje (na verdade, temos agora muito mais desenvolvedores da Microsoft trabalhando na equipe da ASP.NET). Nosso objetivo com o anúncio de hoje é aumentar ainda mais o ciclo de feedback/retorno sobre os produtos, para nos permitir oferecer produtos ainda melhores. Estamos realmente entusiasmados com as melhorias que isso trará. Saiba mais Agora você pode navegar, sincronizar e construir a árvore de código fonte da ASP.NET MVC, Web API, e Razor através do website http://aspnetwebstack.codeplex.com.  O repositório Git atual no site refere-se à árvore de desenvolvimento do marco RC (release candidate/candidata a lançamento) na qual equipe vem trabalhando nas últimas semanas, e esta mesma árvore contém ambos o código fonte e os testes, e pode ser construída e testada por qualquer pessoa. Devido aos binários produzidos serem bin-deployable (DLLs instaladas diretamente na pasta bin sem demais dependências), isto permite a você compilar seus próprios builds e experimentar as atualizações do produto, tão logo elas sejam adicionadas no repositório. Agora você também pode contribuir diretamente para o desenvolvimento dos produtos através da revisão e envio de feedback sobre os checkins de código, enviando bugs e ajudando-nos a verificar as correções tão logo elas sejam enviadas para o repositório, sugerindo e dando feedback sobre os novos recursos enquanto eles são implementados, bem como enviando suas próprias correções ou contribuições de código. Note que todas as submissões de código serão rigorosamente analisadas ??e testadas pelo Time da ASP.NET MVC, e apenas aquelas que atenderem a um padrão elevado de qualidade e adequação ao roadmap (roteiro) definido para as próximas versões serão incorporadas ao código fonte do produto. Sumário Todos nós da equipe estamos realmente entusiasmados com o anúncio de hoje - isto é algo no qual nós estivemos trabalhando por muitos anos. O estreitamento no relacionamento entre a comunidade e os desenvolvedores nos permitirá construir produtos ainda melhores levando a ASP.NET para o próximo nível em termos de inovação e foco no cliente.

• ASP.NET MVC, Web API, Razor and Open Source

  - by ScottGu

  Microsoft has made the source code of ASP.NET MVC available under an open source license since the first V1 release. We’ve also integrated a number of great open source technologies into the product, and now ship jQuery, jQuery UI, jQuery Mobile, jQuery Validation, Modernizr.js, NuGet, Knockout.js and JSON.NET as part of it. I’m very excited to announce today that we will also release the source code for ASP.NET Web API and ASP.NET Web Pages (aka Razor) under an open source license (Apache 2.0), and that we will increase the development transparency of all three projects by hosting their code repositories on CodePlex (using the new Git support announced last week). Doing so will enable a more open development model where everyone in the community will be able to engage and provide feedback on code checkins, bug-fixes, new feature development, and build and test the products on a daily basis using the most up-to-date version of the source code and tests. We will also for the first time allow developers outside of Microsoft to submit patches and code contributions that the Microsoft development team will review for potential inclusion in the products. We announced a similar open development approach with the Windows Azure SDK last December, and have found it to be a great way to build an even tighter feedback loop with developers – and ultimately deliver even better products as a result. Very importantly - ASP.NET MVC, Web API and Razor will continue to be fully supported Microsoft products that ship both standalone as well as part of Visual Studio (the same as they do today). They will also continue to be staffed by the same Microsoft developers that build them today (in fact, we have more Microsoft developers working on the ASP.NET team now than ever before). Our goal with today’s announcement is to increase the feedback loop on the products even more, and allow us to deliver even better products.  We are really excited about the improvements this will bring. Learn More You can now browse, sync and build the source tree of ASP.NET MVC, Web API, and Razor on the http://aspnetwebstack.codeplex.com web-site.  The Git repository on the site is the live RC milestone development tree that the team has been working on the last several weeks, and the tree contains both the runtime sources + tests, and is buildable and testable by anyone.  Because the binaries produced are bin-deployable, this allows you to compile your own builds and try product updates out as soon as they are checked-in. You can also now contribute directly to the development of the products by reviewing and sending feedback on code checkins, submitting bugs and helping us verify fixes as they are checked in, suggesting and giving feedback on new features as they are implemented, as well as by submitting code fixes or code contributions of your own. Note that all code submissions will be rigorously reviewed and tested by the ASP.NET MVC Team, and only those that meet an extremely high bar for both quality and design/roadmap appropriateness will be merged into the source. Summary All of us on the team are really excited about today’s announcement – it has been something we’ve been working toward for many years.  The tighter feedback loop is going to enable us to build even better products, and take ASP.NET to the next level in terms of innovation and customer focus. Thanks, Scott P.S. In addition to blogging, I use Twitter to-do quick posts and share links. My Twitter handle is: @scottgu

• How can I best manage making open source code releases from my company's confidential research code?

  - by DeveloperDon

  My company (let's call them Acme Technology) has a library of approximately one thousand source files that originally came from its Acme Labs research group, incubated in a development group for a couple years, and has more recently been provided to a handful of customers under non-disclosure. Acme is getting ready to release perhaps 75% of the code to the open source community. The other 25% would be released later, but for now, is either not ready for customer use or contains code related to future innovations they need to keep out of the hands of competitors. The code is presently formatted with #ifdefs that permit the same code base to work with the pre-production platforms that will be available to university researchers and a much wider range of commercial customers once it goes to open source, while at the same time being available for experimentation and prototyping and forward compatibility testing with the future platform. Keeping a single code base is considered essential for the economics (and sanity) of my group who would have a tough time maintaining two copies in parallel. Files in our current base look something like this: > // Copyright 2012 (C) Acme Technology, All Rights Reserved. > // Very large, often varied and restrictive copyright license in English and French, > // sometimes also embedded in make files and shell scripts with varied > // comment styles. > > > ... Usual header stuff... > > void initTechnologyLibrary() { > nuiInterface(on); > #ifdef UNDER_RESEARCH > holographicVisualization(on); > #endif > } And we would like to convert them to something like: > // GPL Copyright (C) Acme Technology Labs 2012, Some rights reserved. > // Acme appreciates your interest in its technology, please contact [email protected] > // for technical support, and www.acme.com/emergingTech for updates and RSS feed. > > ... Usual header stuff... > > void initTechnologyLibrary() { > nuiInterface(on); > } Is there a tool, parse library, or popular script that can replace the copyright and strip out not just #ifdefs, but variations like #if defined(UNDER_RESEARCH), etc.? The code is presently in Git and would likely be hosted somewhere that uses Git. Would there be a way to safely link repositories together so we can efficiently reintegrate our improvements with the open source versions? Advice about other pitfalls is welcome.

• Azure Mobile Services: lessons learned

  - by svdoever

  When I first started using Azure Mobile Services I thought of it as a nice way to: authenticate my users - login using Twitter, Google, Facebook, Windows Live create tables, and use the client code to create the columns in the table because that is not possible in the Azure Mobile Services UI run some Javascript code on the table crud actions (Insert, Update, Delete, Read) schedule a Javascript to run any 15 or more minutes I had no idea of the magic that was happening inside… where is the data stored? Is it a kind of big table, are relationships between tables possible? those Javascripts on the table crud actions, is that interpreted, what is that exactly? After working for some time with Azure Mobile Services I became a lot wiser: Those tables are just normal tables in an Azure SQL Server 2012 Creating the table columns through client code sucks, at least from my Javascript code, because the columns are deducted from the sent JSON data, and a datetime field is sent as string in JSON, so a string type column is created instead of a datetime column You can connect with SQL Management Studio to the Azure SQL Server, and although you can’t manage your columns through the SQL Management Studio UI, it is possible to just run SQL scripts to drop and create tables and indices When you create a table through SQL script, add the table with the same name in the Azure Mobile Services UI to hook it up and be able to access the table through the provided abstraction layer You can also go to the SQL Database through the Azure Mobile Services UI, and from there get in a web based SQL management studio where you can create columns and manage your data The table crud scripts and the scheduler scripts are full blown node.js scripts, introducing a lot of power with great performance The web based script editor is really powerful, I do most of my editing currently in the editor which has syntax highlighting and code completing. While editing the code JsHint is used for script validation. The documentation on Azure Mobile Services is… suboptimal. It is such a pity that there is no way to comment on it so the community could fill in the missing holes, like which node modules are already loaded, and which modules are available on Azure Mobile Services. Soon I was hacking away on Azure Mobile Services, creating my own database tables through script, and abusing the read script of an empty table named query to implement my own set of “services”. The latest updates to Azure Mobile Services described in the following posts added some great new features like creating web API’s, use shared code from your scripts, command line tools for managing Azure Mobile Services (upload and download scripts for example), support for node modules and git support: http://weblogs.asp.net/scottgu/archive/2013/06/14/windows-azure-major-updates-for-mobile-backend-development.aspx http://blogs.msdn.com/b/carlosfigueira/archive/2013/06/14/custom-apis-in-azure-mobile-services.aspx http://blogs.msdn.com/b/carlosfigueira/archive/2013/06/19/custom-api-in-azure-mobile-services-client-sdks.aspx In the mean time I rewrote all my “service-like” table scripts to API scripts, which works like a breeze. Bad thing with the current state of Azure Mobile Services is that the git support is not working if you are a co-administrator of your Azure subscription, and not and administrator (as in my case). Another bad thing is that Cross Origin Request Sharing (CORS) is not supported for the API yet, so no go yet from the browser client for API’s, which is my case. See http://social.msdn.microsoft.com/Forums/windowsazure/en-US/2b79c5ea-d187-4c2b-823a-3f3e0559829d/known-limitations-for-source-control-and-custom-api-features for more on these and other limitations. In his talk at Build 2013 Josh Twist showed that there is a work-around for accessing shared script code from the table scripts as well (another limitation mentioned in the post above). I could not find that code in the Votabl2 code example from the presentation at https://github.com/joshtwist/votabl2, but we can grab it from the presentation when it comes online on Channel9. By the way: you can always express your needs and ideas at http://mobileservices.uservoice.com, that’s the place they are listening to (I hope!).

• Heroku and Github integration (how to structure the project)

  - by Noah

  I'm creating a webservice and I want to store the source on github and run the app on heroku. I haven't seen my exact scenario addressed anywhere on the 'net so far, so I'll ask it here: I want to have the following directory structure: /project .git README <-- project readme file TODO.otl <-- project outline ... <-- other project-related stuff /my_rails_app app config ... README <-- rails' readme file In the above, project corresponds to http://github.com/myuser/project, and my_rails_app is the code that should be pushed to heroku. Do I need a separate branch for the rails app, or is there a simpler way that I'm missing? I guess my project-related non-rails files could live in my_rails_app, but the rails README already lives there and it seems inconsistent to overwrite that. However, if I leave it, my github page for the rails app will contain the rails readme, which makes no sense. Thanks, Noah P.S. I tried just setting it up as described above and running git push heroku from the main project folder. Of course, heroku doesn't know I want to deploy the subfolder: -----> Heroku receiving push ! Heroku push rejected, no Rails or Rack app detected.

• "Pretty" Continuous Integration for Python

  - by dbr

  This is a slightly.. vain question, but BuildBot's output isn't particularly nice to look at.. For example, compared to.. phpUnderControl Hudson CruiseControl.rb ..and others, BuildBot looks rather.. archaic I'm currently playing with Hudson, but it is very Java-centric (although with this guide, I found it easier to setup than BuildBot, and produced more info) Basically: is there any Continuous Integration systems aimed at python, that produce lots of shiney graphs and the likes? Update: After trying a few alternatives, I think I'll stick with Hudson. Integrity was nice and simple, but quite limited. I think Buildbot is better suited to having numerous build-slaves, rather than everything running on a single machine like I was using it. Setting Hudson up for a Python project was pretty simple: Download Hudson from https://hudson.dev.java.net/ Run it with java -jar hudson.war Open the web interface on the default address of http://localhost:8080 Go to Manage Hudson, Plugins, click "Update" or similar Install the Git plugin (I had to set the git path in the Hudson global preferences) Create a new project, enter the repository, SCM polling intervals and so on Install nosetests via easy_install if it's not already In the a build step, add nosetests --with-xunit --verbose Check "Publish JUnit test result report" and set "Test report XMLs" to **/nosetests.xml That's all that's required. You can setup email notifications, and the plugins are worth a look. A few I'm currently using for Python projects: SLOCCount plugin to count lines of code (and graph it!) - you need to install sloccount separately Violations to parse the PyLint output (you can setup warning thresholds, graph the number of violations over each build) Cobertura can parse the coverage.py output. Nosetest can gather coverage while running your tests, using nosetests --with-coverage (this writes the output to **/coverage.xml)

• Good DB Migrations for CakePHP?

  - by Martin Westin

  Hi, I have been trying a few migration scripts for CakePHP but I ran into problems with all of the in some form or another. Please advice me on a migration option for Cake that you use live and know works. I'd like the following "features": -Support CakePHP 1.2(e.g. CakeDCs migrations will only be an option when 1.3 is stable and my app migrated to the new codebase) -Support for (or at least not halt on) Models with a different database config. -Support Models in sub-folders of app/models -Support Models in plugins -Support tables that do not conform to Cake conventions (I have a few special tables that do not have a single primary key field and need to keep them) -Plays well with automated deployment via Capistrano and Git. I do not need rails-style versioned files a git versioned schema file that is compared live to the existing schema will do. That is: I like the SchemaShell in Cake apart from it not being compatible with most of my requirements above. I have looked at and tested: CakePHP Schema Shell http://book.cakephp.org/view/734/Schema-management-and-migrations CakeDC migrations http://cakedc.com/downloads/view/cakephp_migrations_plugin YAML migrations http://github.com/georgious/cakephp-yaml-migrations-and-fixtures joelmoss migrations http://code.google.com/p/cakephp-migrations

• Database structure and source control - best practice

  - by Paddy

  Background I came from several years working in a company where all the database objects were stored in source control, one file per object. We had a list of all the objects that was maintained when new items were added (to allow us to have scripts run in order and handle dependencies) and a VB script that ran to create one big script for running against the database. All the tables were 'create if not exists' and all the SP's etc. were drop and recreate. Up to the present and I am now working in a place where the database is the master and there is no source control for DB objects, but we do use redgate's tools for updating our production database (SQL compare), which is very handy, and requires little work. Question How do you handle your DB objects? I like to have them under source control (and, as we're using GIT, I'd like to be able to handle merge conflicts in the scripts, rather than the DB), but I'm going to be pressed to get past the ease of using SQL compare to update the database. I don't really want to have us updating scripts in GIT and then using SQL compare to update the production database from our DEV DB, as I'd rather have 'one version of the truth', but I don't really want to get into re-writing a custom bit of software to bundle the whole lot of scripts together. I think that visual studio database edition may do something similar to this, but I'm not sure if we will have the budget for it. I'm sure that this has been asked to death, but I can't find anything that seems to quite have the answer I'm looking for. Similar to this, but not quite the same: http://stackoverflow.com/questions/340614/what-are-the-best-practices-for-database-scripts-under-code-control

• Industry-style practices for increasing productivity in a small scientific environment

  - by drachenfels

  Hi, I work in a small, independent scientific lab in a university in the United States, and it has come to my notice that, compared with a lot of practices that are ostensibly followed in the industry, like daily checkout into a version control system, use of a single IDE/editor for all languages (like emacs), etc, we follow rather shoddy programming practices. So, I was thinking of getting together all my programs, scripts, etc, and building a streamlined environment to increase productivity. I'd like suggestions from people on Stack Overflow for the same. Here is my primary plan.: I use MATLAB, C and Python scripts, and I'd like to edit, compile them from a single editor, and ensure correct version control. (questions/things for which I'd like suggestions are in italics) 1] Install Cygwin, and get it to work well with Windows so I can use git or a similar version control system (is there a DVCS which can work directly from the windows CLI, so I can skip the Cygwin step?). 2] Set up emacs to work with C, Python, and MATLAB files, so I can edit and compile all three at once from a single editor (say, emacs) (I'm not very familiar with the emacs menu, but is there a way to set the path to the compiler for certain languages? I know I can Google this, but emacs documentation has proved very hard for me to read so far, so I'd appreciate it if someone told me in simple language) 3] Start checking in code at the end of each day or half-day so as to maintain a proper path of progress of my code (two questions), can you checkout files directly from emacs? is there a way to checkout LabVIEW files into a DVCS like git? Lastly, I'd like to apologize for the rather vague nature of the question, and hope I shall learn to ask better questions over time. I'd appreciate it if people gave their suggestions, though, and point to any resources which may help me learn.

• How to architect Rails site that can be edited while running?

  - by Chris Kimpton

  Hi, I am writing a Rails app that "scrapes/navigates" some other websites and webservices for content. I am using Mechanize and Savon to do the heavylifting. But given the dynamic nature of the web, I'd like to make my calls to these editable by the admin users of the site - rather than requiring me to release a new version of the site. The actual scraping thread happens async to the website, using the daemons gem. My requirements are: Thinking that the scraping/webservice calling code is quite simple, the easiest route is to make the whole class editable by the admins. Keep a history of the scraping code - so that we can fairly easily revert if we introduce a problem. Initially use the code from the file system, but as soon as thats been edited and stored somewhere, to use that code instead. I am thinking my options are: Store the code in the db (with a history table for the old versions) Store the code in a private git repo somewhere and access that for the history/latest versions. I am thinking the git route might be easiest, given its raison d'etre is to track file history... But perhaps there is a gem/plugin that does all this for me, out of the box? Thanks in advance for any tips/advice. ~chris

• Vim, LaTeX, and version controlI

  - by Bkkbrad

  I'm writing a LaTeX document in vim, and I have it hard wrapping at 80 characters to make reading easier. However, this causes problems with tracking changes with in version control. For example, inserting "Lorem ipsum" at the beginning of this text: 1 Dolor sit amet, consectetur adipiscing elit. Phasellus bibendum lobortis lectus 2 quis porta. Aenean vestibulum magna vel purus laoreet at molestie massa 3 suscipit. Vestibulum vestibulum, mauris nec convallis ultrices, tellus sapien 4 ullamcorper elit, dignissim consectetur justo tellus et nunc. results in: 1 Lorum ipsum dolor sit amet, consectetur adipiscing elit. Phasellus bibendum 2 lobortis lectus quis porta. Aenean vestibulum magna vel purus laoreet at 3 molestie massa suscipit. Vestibulum vestibulum, mauris nec convallis ultrices, 4 tellus sapien ullamcorper elit, dignissim consectetur justo tellus et nunc. When I review this change in git, it tells me that all the lines of the paragraph have changed because of the wrapping, even though only one semantic change has occurred. One way around this problem is to have every sentence on its own line. This looks the same in the rendered document, but the source now is harder to read, because each line has quite a different line length: 1 Lorum ipsum dolor sit amet, consectetur adipiscing elit. 2 Phasellus bibendum lobortis lectus quis porta. 3 Aenean vestibulum magna vel purus laoreet at molestie massa suscipit. 4 Vestibulum vestibulum, mauris nec convallis ultrices, tellus sapien ullamcorper elit, dignissim consectetur justo tellus et nunc. (If I soft wrap at 80, things still look bad, just in a different way.) Is it possible to have my text on disk with one newline per sentence, but display and edit it in vim as if the text of each paragraph was one long line, soft wrapped at 80 characters? I assume it requires some vim-foo rather than tweaking git or LaTeX.

• Java SSH2 libraries in depth: Trilead/Ganymed/Orion [/other?]

  - by Bernd Haug

  I have been searching for a pure Java SSH library to use for a project. The single most important needed feature is that it has to be able to work with command-line git, but remote-controlling command-line tools is also important. A pretty common choice, e.g. used in the IntelliJ IDEA git integration (which works very well), seems to be Trilead SSH2. Looking at their website, it's not being maintained any more. Trilead seems to have been a fork of Ganymed SSH2, which was a ETH Zurich project that didn't see releases for a while, but had a recent release by its new owner, Christian Plattner. There is another actively maintained fork from that code base, Orion SSH, that saw an even more recent release, but which seems to get mentioned online much less than the other 2 forks. Has anybody here worked with any of (or, if possible, both) of Ganymed and Orion and could kindly describe the development experience with either/both? Accuracy of documentation [existence of documentation?], stability, buggyness... - all of these would be highly interesting to me. Performance is not so important for my current project. If there is another pure-Java SSH implementation that should be used instead, please feel free to mention it, but please don't just mention a name...describe your judgment from actual experience. Sorry if this question may seem a bit "do my homework"-y, but I've really searched for reviews. Everything out there seems to be either a listing of implementations or short "use this! it's great!" snippets.

• Capistrano fails for multiple host deployments

  - by morris082

  I be at a loss here, and after scouring the seas (read: internet) for solutions I am left with none other than to hit up the stack. any help appreciated. I have capistrano running locally for deployments onto several different environments. (I'm on windows 7, fwiw). All was well until I needed to deploy to multiple :app servers during a single deployment. Usually I'm prompted for my ssh passphrase once when I call 'cap deploy'. I have ssh-agent running (git never pesters for my pass) but despite this Capistrano has always bugged me once each deployment. Regardless, it always worked when deploying to ONE host. Now, when I attempt to deploy to multiple servers at once, it asks for my passphrase what appears to be multiple times: (ips removed by ME) servers: ["redacted", "redacted"]<br /> Enter passphrase for ~/.ssh/id_rsa: Enter passphrase for ~/.ssh/id_rsa: So with the above I enter my passphrase but this doesn't work. It waits as little while, then spits out this error: connection failed for: <one of the server ips> (NoMethodError: undefined method `overwrite' for nil:NilClass) And that's the end of that. I can "passwordless" ssh into the servers I'm deploying on just fine. I'm pretty certain the ssh-agent is running since I can hit Git w/out entering my passphrase every time Using 'forward_agent' setting in cap deploy did not work. This is my role: role :app, "ip 1 removed", "ip 2 removed" If i set default_run_options[:max_hosts] = 1, it works OK but it asks for my passphrase for every single connection to each host I'm deploying to.. which ends up being a lot. Essentially I'm looking for any of the below (but not limited to): - "You're never going to fix that on windows" - "This is how you get REAL passwordless deployment in capistrano" - "Have you overlooked this setting/feature?" - "I have a rock that can fix anything, you may borrow it" Thanks!

• rails not recognizing project

  - by tipu

  I can create a new project using rails and I can use stuff like rails migration ... and i (correctly) get a error because the sqlite gem is missing. but when i try using rails migration ... with a project i checked out from github, it doesn't recognize that it is a rails project i get: Usage: rails new APP_PATH [options] Options: -d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db) # Default: sqlite3 -O, [--skip-active-record] # Skip Active Record files [--dev] # Setup the application with Gemfile pointing to your Rails checkout -J, [--skip-prototype] # Skip Prototype files -T, [--skip-test-unit] # Skip Test::Unit files -G, [--skip-git] # Skip Git ignores and keeps -b, [--builder=BUILDER] # Path to an application builder (can be a filesystem path or URL) [--edge] # Setup the application with Gemfile pointing to Rails repository -m, [--template=TEMPLATE] # Path to an application template (can be a filesystem path or URL) -r, [--ruby=PATH] # Path to the Ruby binary of your choice # Default: /usr/bin/ruby1.8 [--skip-gemfile] # Don't create a Gemfile and it goes on. any ideas? edit: it's probably an important detail that earlier my rails wasn't working at all. i had to cp /usr/bin/ruby to /usr/bin/local/ruby

• Which DVCS would work best on Windows for my scenario?

  - by PoorLuzer

  At work I use ClearCase and SourceSafe, but have found some time to do some time to code for myself enroute thanks to a disposable laptop. However, I wish I had a lightweight VCS on my system using which I would be able to make changes to my code during the commute and then push/grab them from my Linux systems. I use git on my home system, but I can't really get it working on Windows. I don't want all that cygwin hack. If it does not run natively on Windows, it just won't do. What have you guys tried on your Windows system? Something that YOU use. The big player at the moment seems to be Mercurial? What would be best for a one (or maybe two) man team? I just need to maintain : Versioned copies of source code. Checking in and out should be as less obtrusive as possible. I am looking forward to a multiple Undo kind of feature (like that in an EMacs buffer) but persistent. I really like the way git keeps track of lines moving between files in a source code set I should be able to move part(s)/sub tree(s) of the source tree (each sub tree implies a module/plugin to my the main software I am building) to an archival system either completly or partially and restore them back from the archive as and when required and the system should track any changes to this tree as well. I actually want to experiment with my code as much as possible without me manually keeping track of what I modified and what I need to undo once I try out some idea, so that I am back to where I want to continue from. Notes : A similar topic came up a year ago : http://stackoverflow.com/questions/4670/dvcs-choices-whats-good-for-windows I hope things have changed, and I really want people to share their own, real life experiences. Not something they recommend without using it or they think will work.

• Maven exec bash script and save output as property

  - by djechlin

  I'm wondering if there exists a Maven plugin that runs a bash script and saves the results of it into a property. My actual use case is to get the git source version. I found one plugin available online but it didn't look well tested, and it occurred to me that a plugin as simple as the one in the title of this post is all I need. Plugin would look something like: <plugin>maven-run-script-plugin> <phase>process-resources</phase> <!-- not sure where most intelligent --> <configuration> <script>"git rev-parse HEAD"</script> <!-- must run from build directory --> <targetProperty>"properties.gitVersion"</targetProperty> </configuration> </plugin> Of course necessary to make sure this happens before the property will be needed, and in my case I want to use this property to process a source file.
