A ActionView::MissingTemplate occurred in posts#destroy:

Missing template posts/destroy with {:formats=>[:html], :locale=>[:en, :en], :handlers=>[:rjs, :rhtml, :rxml, :erb, :builder]} in view paths...

This exception is raised when you’re missing the template for responding to a request of a certain format. So, if the browser requested HTML and you only expected to receive JS, you might simply modify your controller action like so:

respond_to do |format|
  format.js
end

This specifies that you’re only going to respond to JS requests, and any others will be served a 406 “not_acceptable” response, which will quiet down that exception noise.

Have you handled these in some other way? If so, please let me know!

Commit to that branch locally and regularly push your work to the same named branch on the server
When you need feedback or help, or you think the branch is ready for merging, open a pull request
After someone else has reviewed and signed off on the feature, you can merge it into master
Once it is merged and pushed to ‘master’, you can and should deploy immediately

On Being A Journeyman Software Developer: Being honest vs Making excuses

Often times, we choose to be in certain situations and then, rather than admitting that the situation is bad and dysfunctional, then convince ourselves — and justify to others — that this is the only way it can be. While we are free to choose trade-offs for whatever situation we place ourselves in, it is important to be honest with ourselves about the causes of the situation.

Throw, Catch, Raise, Rescue… I’m so confused!

Ruby is a language that tries to anticipate your needs as a programmer. One common need is a way to terminate execution early when we find there is no further work to be done. Unlike in some languages, where we would have to either abuse the exception mechanism or use multiple loop breaks and method returns to achieve the same effect, Ruby provides us with the catch and throw mechanism to quickly and cleanly make an early escape. This leaves begin/raise/rescue free to be used for errors, and nothing else.

Scaling a web site using HTTP caching and JS async calls | Merbist

The challenge is that a lot of people using the Rails framework are used to doing page caching instead of relying on HTTP caching, even though this feature was added a long time ago. The major problem with page caching is that it doesn’t scale that well as soon as you run more than one server. Indeed you would need to store the page content to a shared drive between your servers or use memcached and do some work to avoid hitting your app every single time. On the other hand, HTTP caching is extremely easy to handle at the application level and it will dramatically reduce the amount of requests hitting your app. Let me explain a little more about HTTP caching.

How to take advantage of Redis just adding it to your stack

Redis is different than other database solutions in many ways: it uses memory as main storage support and disk only for persistence, the data model is pretty unique, it is single threaded and so forth. I think that another big difference is that in order to take advantage of Redis in your production environment you don’t need to switch to Redis. You can just use it in order to do new things that were not possible before, or in order to fix old problems.

For each good idea, there were a large number of stupid ones that didn’t work out. Failing, for this successful designer, was a way to find the good ideas.

You’d have a dyno that should (in terms of memory) be able to spin up 3 or 4 instances, but you were only able to spin up a single Thin instance per dyno. With Thin, even after the introduction of Cedar, this is still the case. But now since the application server constraint no longer exists, you can use Unicorn to do it. With this, you should be able to improve your application’s throughput by a factor of 3 to 4 on the same dyno.

Legacy Development with Pow « Stuff… And Things…

However, there is a downside:  Pow doesn’t play nicely with Apache (or any server listening on port 80). Life isn’t all greenfield, if in the course of the day you need to work on PHP or CGI legacy apps Pow is not so simple.   Pow creates a firewall rule that redirects port 80 to its port; to access Apache you need to either toggle the firewall rule on and off or move Apache to a different port all together. And now you’re running two web servers.  There has to be a better way.

The unix process model is a powerful way to approach running your web app. Procfile gives us a way to declare process types, and Foreman gives us an easy way to run the app’s processes in both development and deployment environments.

Tech Notes: Complexity is the enemy

Another word for this problem is cleverness: to quote another one of the C hackers, “Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.”

Edge Rails.info :: ActiveRecord Identity Map

If you’ve been using rails for a while now you may be familiar with Active Record’s query cache. The query cache is a powerful part of Active Record which reduces unnecessary SQL calls and provides general speed improvements, especially when dealing with associations. The problem with the query cache, however, is when retrieving two identical records from the database two in-memory objects will still be created.

How to Play with Rails 3.1, CoffeeScript and All That Jazz Right Now

Maybe I’m weird (actually, there’s no maybe about it) but when I first heard about Rails 3.1 getting CoffeeScript and Sass out of the box, I wanted to see how it worked and how smooth the process would be. So like quite a few people on IRC I’ve seen, I installed edge Rails (currently 3.1.0-beta) and got playing. (Yes, it’s PRE-RELEASE. Expect mischief!)

Rails 3.1 Adopts CoffeeScript, jQuery, Sass and.. Controversy

I’m glad David’s stepping into these sorts of discussions again. He seemed to fade away during the year before Rails 3 came out, leaving a lot of the “thought leadership” to Yehuda Katz. Now he’s back on top form and talking sense – long may it last.

The Quest Continues: Introducing capybara-webkit – GIANT ROBOTS SMASHING INTO OTHER GIANT ROBOTS

What we need was a real rendering engine coupled with a full Javascript and DOM implementation, but without all the cruft of a GUI browser. What we really wanted was a headless implementation of WebKit’s rendering engine that could be driven by Capybara tests. After Tristan “Websockets” Dunn showed me PhantomJs, I realized this might be possible using Qt’s WebKit implementation.

meskyanichi/hirefire – GitHub

HireFire automatically “hires” and “fires” (aka “scales”) Delayed Job (and soon Resque too!) workers on Heroku. When there are no queue jobs, HireFire will fire (shut down) all workers. If there are queued jobs, then it’ll hire (spin up) workers. The amount of workers that get hired depends on the amount of queued jobs (the ratio can be configured by you). HireFire is great for both high, mid and low traffic applications. It can save you a lot of money by only hiring workers when there are pending jobs, and then firing them again once all the jobs have been processed. It’s also capable to dramatically reducing processing time by automatically hiring more workers when the queue size increases.

Launching Trajectory: Communication Builds Better Software – GIANT ROBOTS SMASHING INTO OTHER GIANT ROBOTS

Over the past 8 years, we’ve used many tools for project communication and planning and we tried very hard to not write our own. The latest combination was Basecamp and Pivotal Tracker. Basecamp was great for discussion and communication. Pivotal Tracker was great for user stories and emergent planning.

However, we’ve grown tired of having one tool that designers love, one tool that developers love, and no tool that clients love.

8 Ways Companies Can Contribute to Open Source Communities

Permit (freely encourage) your developers to engage with the OSS community around each project. They, and your company, will get two primary benefits: You will gain a more intimate understanding of the projects, and you will have social and productive relationships with the other core developers and contributors in the community. It’s easy to ask a friend to help solve a problem. The first step is to contribute to their project; friendship and partnership will follow.

Official Google Blog: +1’s: the right recommendations right when you want them—in your search results

Today we’re taking that a step further, enabling you to share recommendations with the world right in Google’s search results. It’s called +1—the digital shorthand for “this is pretty cool.” To recommend something, all you have to do is click +1 on a webpage or ad you find useful. These +1’s will then start appearing in Google’s search results.

Thoughts on testing – part 1 – Object Reload

It doesn’t take a genius to realise that testing is a very personal matter. From Test::Unit purists to RSpec evangelists, everyone has their own take on testing Ruby code. And whilst we believe that not only there are no silver bullets in most of the problems in software development but personal preferences make it unlikely that there will ever be any, we’d like to share our thoughts about testing in this series of posts. We hope it will be as enjoyable for you to read as it was for us to write.

jamesgolick/always_verify_ssl_certificates – GitHub

Ruby’s net/http is setup to never verify SSL certificates by default. Most ruby libraries do the same. That means that you’re not verifying the identity of the server you’re communicating with and are therefore exposed to man in the middle attacks. This gem monkey-patches net/http to force certificate verification and make turning it off impossible.

Adding additional processing support to CarrierWave » Transcending Frontiers

Thankfully, CarrierWave provides an easy way to extend the default functionality so we can do more.

Rails 3 + Devise + Uploadify = No Flash Session Hacks

So, this token authentication got me thinking. Instead of sending an encoded string with session information to flash, which in turn sends it to the server, which in turn hacks it into an actual session, I could just send the user’s authentication token along! No sever-side hacks required – it’s all built in into devise already!

Ryan Singer at Future of Web Apps, London 2010 on Vimeo

Here’s a talk I gave at Future of Web Apps 2010 in London. In this talk, I walk through the steps of creating a web app including modeling, sketching, HTML, Photoshop explorations, and moving from static mockups to live running code. Each step is illustrated with a real example, including some live sketching and live HTML. I also wanted to give a sense of how we think about apps at 37signals, as a stack of different levels that we can iterate on individually.

Visualizing a product’s UI and code layers – (Ryan Singer)

If I ask you to visualize a software product, a picture of the interface probably comes to mind. From the user’s perspective, the interface is the product. For us on the development side, the product is more than that. It’s the interface, the code, the connections from code to UI, the separations of concerns and the boundaries between features.

Javascript integration testing example: installing and using Mixpanel – GIANT ROBOTS SMASHING INTO OTHER GIANT ROBOTS

We’ve been on a quest for years to make sure our integration tests covered the Javascript components of the app. We noted in November that we felt the community had reached an important plateau with a toolset of Cucumber, Capybara, and Akephalos.

While still frequently painful, our default mentality on new projects is “we will be able to test the Javascript components of this app in our usual integration tests.”

Serve is a small Rack-based web server and rapid prototyping framework for Web applications (specifically Rails apps). It is designed to compliment web application development and enforce a strict separation of concerns between designer and developer. Using Serve allows the designer to work in a separate prototype project, while the developer can work on the actual application and utilize resources from the prototype as needed. This allows the designer to focus on presentation and flow, while the developer can focus on implementation.

I don’t work for reddit anymore (as of about a week ago, although I didn’t get as much fanfare as raldi did), but I can tell you that they’re giving Amazon too much credit here. Amazon’s EBSs are a barrel of laughs in terms of performance and reliability and are a constant (and the single largest) source of failure across reddit.
