Ruby on Rails development notes, tips, practices

Development

• Performance tuning tools:
• New Relic
• Useful tips:
• Use rails console to counter check the SQL statements being executed.

Testing

• Unit tests should be written in a way that adding new records in test fixtures shouldn't affect the previous test results.  
• New test fixtures should be added in a way that they should link to existing fixture data so as to avoid breaking existing test cases.

Quality Assurance

• Besides unit, functional and integration test within rails framework.  Create automated browser test using tools like "Selenium" over test/real data.

Maintenance

• Avoid using unnecessary code reflection.  It's not good for performance and maintenance.

Selected web resources and news feeds

• www.programmableweb.com - Keeping you up to date with APIs, mashups and the Web as platform.
• highscalability.com - Building bigger, faster and more reliable websites.
• aws.amazon.com - Amazon web services.
• linux.vbird.org - Comprehensive linux guide .... in Chinese.
• channel9.msdn.com - The microsoft community.
• engineering.twitter.com - Twitter's engineering blog.

System design tips

General tips for develop web based system.

• Action Audits - Keep track of user actions.  In Rails, system may log controller actions and corresponding params and response of every single request.
• Bug/Error tracking - Every error triggered in system should be notified to developers.
• Timestamps - Always keep creation, update and any other timestamps on every records in database.

(to be cont.)

General guidelines for team software development

Development Environment

• Source control - e.g. Git (preferred choice) , Csv, Svn
• May use internal server or public source controls (e.g. Github/ Unfuddle)
• Team members should receive notification whenever there's new push/commit to the server repository.
• Knowledge base - Wiki
• Team members should try to contribute on:
• Project documentations
• Technical know-hows
• Workflow control for agile development.  Some choices:
• Simple and easy to use - Pivotal Tracker
• More comprehensive one - Atlassian JIRA  
• Continuous integration - Build and test server.  For example:
• Jenkins - For Ruby on Rails developments
• CuriseControl.NET - For .NET developments
• Test Automation
• Browser test - Selenium IDE

General Coding Practices

• DRY - Don't repeat yourself.  Never copy and paste same (similar) block of code in multiple places within the project.  Instead, common functionalities should be "extracted" to a single access point like a helper function or by other means.
• Coding conversions - Team members should follow a single set of coding conversion.
• Try to keep each line under 120 to 150 chars.
• Code with comments.
• Should always keep the code clean and easy for maintenance.
• Should keep small code source files.  Every source code file should in general not more than 500 or even 300 lines (excluding large blocks of comments).
• Should keep small functions - not more than 30 to 50 lines.
• Should keep functions as private/protected as possible.  Only expose a function to public whenever necessary.
• Every single function/method should be unit tested.
• Regular code coverage test.
• Developers may keep a work diary to log everyday's work done.

Daily Collaboration Practices

• Team members MUST complete test (unit, functional, integration test) and make sure there's no unexpected error before pushing code to repository.
• The build server (e.g. Jenkins/CuriseControl.NET) should run complete test whenever there's code update on repository.  In this way, whoever broke any tests can be clearly identified.
• If there's unexpected errors (except explicit NotImplementedError) reported by build server, whom pushed the related code should fix the errors ASAP.
• Responsibilities - whenever a feature raised a issue/bug need to be fixed/enhanced, the team member(s) who contributed to that feature should be have the priority to follow the case.
• Communications
• Better communications between team members always save development time and avoid unnecessary bugs.
• Always let other team members know what you're working on.
• Pending or unfinished feature can be marked as "NotImplementedException" and let the corresponding test fail.  Then commit code to repository.
• Any bug reported from QA Engineers should state as much details as possible including the environment and steps to reproduce a bug.
• Code review
• Team members should review each others' code.
• For any problem spotted, one should inform the author of that code.  In addition, adding unit tests to indicate the problem may also helps.
• It there's no QA team in the group.  Developer should write additional test cases for each other!  It's always better for a developer to find a bug before the end users!
• All developers should stand by when a new release is deployed to production.
• Business logic and any updates should be kept in a centralized repository such as work flow control or wiki.
• Every developer should try their best to commit/push the work done on that day before leaving the office.

Source Control Usage Practices

• New project feature should be developed on a separated branch.  Then merge back to master/main trunk when finished and tested.
• Project releases should be tagged.

The Passionate Programmer

Marketing

• Both ends of the technology adoption curve might prove to be lucrative.
• You can't compete on price.  In fact, you can't afford to compete on price.
• Supply and demand.  Exploit market imbalances.
• Don't just know how to program.  Now is the time to think about business domains you invest your time in.
• Be the worst guy in every band you're in.
• The people around you affect your own performance.  Choose your crowd wisely.
• I haven't been given the opportunity...? Seize the opportunity!
• Be a generalist.  Generalists are rare...and, therefore, precious.
• Your skill should transcend technology platforms.
• Be a specialist.  Too many of us seem to believe that specializing in something simply means not knowing about other things.
• Don't invest on single technology or platform.  Vendor - centric views are typically myopic.
• Passionate.  Work because you couldn't not work.

Investment

• Learning.   Don't wait to be told.  Ask!
• Learn the business you work for.   You can't creatively help a business until you know how it works.
• Find a teacher.   It's ok to depend on someone.  Just make sure it's the right person.
• Be a teacher.  To find out whether you really know something, try teach it to someone else.
• Be a teacher.  Mentors tend not to get laid off.
• Practice.  Practice at your limits.
• Implementation.  If you want to feel you own a process, help implement it.
• Stand on shoulder of Giant.  Mine existing code for insights.
• Use existing code to reflect on your own capabilities.

Execution

• It's now.  What can we do?  Right Now?
• Mind reading.  The mind - reading trick, if done well, leads to people depending on you.
• Daily report.  Have an accomplishment to report every day.
• Don't forget whom you work for.  Your managers' successes are your successes.
• Satisfaction.  Be ambitious, but don't wear it on your sleeve.
• Get job well done today.  How much more fun could you make your job?
• What's your value?  Ask, "Was I worth it today?"
• Beware of being blinded by your won success.
• Enjoy Maintenance.  Maintenance can be a place of freedom and creativity.
• Concentrate on 8 working hours per day.  Projects are marathons, not sprints.
• Learn from failure.  Every wrong note is but one step away from a right one.
• Stressful times offer the best opportunities to build loyalty.
• Say "No".  Saying "Yes" to avoid disappointment is just lying.
• Don't panic.  Heroes never panic.
• Say it, implement it, demonstrate it.  Status reports can help you market yourself.

Sales

• Don't ignore feelings.  Performance appraisals are never objective.
• Communication is important.  Your customers are afraid of you.
• Communication and documentation.  You are what you can explain.
• Show up.  Learn about your colleagues.
• The right language to the right people.  Market your accomplishments in the language of your business.
• Change the world.  Have a mission.  Make sure people know it.
• Let people hear your voice.  
• Have your own brand.  Your name is your name.
• Google never forgets.
• Publish your code.  Anyone can use Rails.  Few can say Rails contributor.
• Be a master.
• Relationships.  Fear gets between us and the pros.

Leading technologies

• Outdated technologies.  Your shiny new skills are already obsolete.
• You are not your job.
• Endlessness.  Focus on doing, not on being done.
• Create yourself a product roadmap.  
• Notice the market.  Watch the alpha geeks.
• Developer, review themselves.
• Monkey catching trap.  Rigid values make you fragile.
• Avoid waterfall career plannings.  
• Daily improvement.  
• Independent.

Configure IIS 7.0 for Restful web application

When deploys a Restful web application to IIS 7.0 on Windows server 2008, it would certainly returns 404 when trying to access any restful service in the application.

This is because by default the restful request is handled by "StaticFile" handler in IIS.

The quickest way to solve the problem is change the settings in "StaticFile". (Screenshot #1)
- Select the "Executable" be "...\v4.0...\aspnet_isapi.dll"
- Un-check the "Check if file exists" option.

In addtion to that, make sure the application is running on v4.0 classic (Screenshot #3) or you may see a log in Screenshot #2

Apache Hadoop - Distributed computing

What Is Apache Hadoop?
The Apache™ Hadoop® project develops open-source software for reliable, scalable, distributed computing.

The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-avaiability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-availabile service on top of a cluster of computers, each of which may be prone to failures.

Debug SQL Stored Procedure

In general, any database stored procedure can be debugged by inserting printouts within the procedure.  First, create a debug table to store the printouts.  e.g.

your_debug_table {
    id [int]
    message [string]
    timestamp [datetime]
}

Then, in your stored procedure, print messages to debug table.  e.g.

your_stored_procedure {
    ...
    insert into your_debug_table (message) values (your_message);
    ...
}

Firefox Extension Development

Extensions add new functionality to Mozilla applications such as Firefox, SeaMonkey and Thunderbird. They can add anything from a toolbar button to a completely new feature. They allow the application to be customized to fit the personal needs of each user if they need additional features, while keeping the applications small to download.

Extensions are different from plugins, which help the browser display specific content like playing multimedia files. Extensions are also different from search plugins, which plug additional search engines in the search bar.

Scrum - Agile development

Scrum is an iterative and incremental agile software development method for managing software projects and product or application development. Scrum has not only reinforced the interest in project management,[citation needed] but also challenged the conventional ideas about such management. Scrum focuses on project management institutions where it is difficult to plan ahead. Mechanisms of empirical process control, where feedback loops that constitute the core management technique are used as opposed to traditional command-and-control oriented management.[citation needed] It represents a radically new approach for planning and managing projects, bringing decision-making authority to the level of operation properties and certainties.

Artificial Intelligence

Artificial intelligence (AI) is the intelligence of machines and the branch of computer science that aims to create it. AI textbooks define the field as "the study and design of intelligent agents" where an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success. John McCarthy, who coined the term in 1955, defines it as "the science and engineering of making intelligent machines."

Neural network

The term neural network was traditionally used to refer to a network or circuit of biological neurons.[1] The modern usage of the term often refers to artificial neural networks, which are composed of artificial neurons or nodes. Thus the term has two distinct usages:

Biological neural networks are made up of real biological neurons that are connected or functionally related in a nervous system. In the field of neuroscience, they are often identified as groups of neurons that perform a specific physiological function in laboratory analysis.
Artificial neural networks are composed of interconnecting artificial neurons (programming constructs that mimic the properties of biological neurons). Artificial neural networks may either be used to gain an understanding of biological neural networks, or for solving artificial intelligence problems without necessarily creating a model of a real biological system. The real, biological nervous system is highly complex: artificial neural network algorithms attempt to abstract this complexity and focus on what may hypothetically matter most from an information processing point of view. Good performance (e.g. as measured by good predictive ability, low generalization error), or performance mimicking animal or human error patterns, can then be used as one source of evidence towards supporting the hypothesis that the abstraction really captured something important from the point of view of information processing in the brain. Another incentive for these abstractions is to reduce the amount of computation required to simulate artificial neural networks, so as to allow one to experiment with larger networks and train them on larger data sets.
