Using `heroku pg:transfer` to Migrate Postgres Databases Using `pg:transfer` to Migrate Postgres Databases Development of most applications takes place in several disparate environments with the most common pattern being dev-staging-production. While it's necessary for the source versions in each environment to differ it is quite useful to retain some level of data synchronicity between the environments (for example, to populate your local database with production data to diagnose a bug). When managing environments on Heroku the recommendation has been to use Taps and heroku db:pull/heroku db:push to transfer data to and from the remote Postgres database. While Taps aimed to be database-agnostic (allowing you to import/export between different database vendors) this came at the expense of robustness and maintainability. The Heroku pg:transfer CLI plugin is a more stable and predictable tool that automatically transfers data between two Postgres databases using native pg tools and protocols.

My Ultimate Developer and Power Users Tool List for Mac OS X (2012 Edition) This is the fourth installment of my must have must have list of tools and utilities as a Mac and iOS developer (2009, 2010, 2011). A lot can change in twelve months when you work in the technology space. The biggest change for Apple developers each year are the platform updates. This year saw the transition from iOS 5 to 6 as well as Lion turning into a more powerful Mountain Lion. The idea for this list was shamelessly ripped off from Windows developer Scott Hanselman whose list is an enjoyable read every year. Many of the products you will recognize from previous years’ lists. Hardware Though I am currently working on the road, I am still maintaining a dual Mac setup under normal circumstances. Presently I am using my 15” Retina MacBook Pro with a 512GB SSD and 8GB of RAM. I am using Dropbox more than ever to keep everything between the two machines in sync. In terms of accessories and upgrades: I use a Das Keyboard. Software I am really hard on software. The Essential Power User 5

Protocol Buffers are a way of encoding structured data in an efficient yet extensible format. Google uses Protocol Buffers for almost all of its internal RPC protocols and file formats. Latest Updates Documentation Read the documentation. Discussion Visit the discussion group. Quick Example You write a .proto file like this: message Person { required int32 id = 1; required string name = 2; optional string email = 3;} Then you compile it with protoc, the protocol buffer compiler, to produce code in C++, Java, or Python. Then, if you are using C++, you use that code like this: Person person;person.set_id(123);person.set_name("Bob");person.set_email("bob@example.com"); fstream out("person.pb", ios::out | ios::binary | ios::trunc);person.SerializeToOstream(&out);out.close(); Or like this: Person person;fstream in("person.pb", ios::in | ios::binary);if (!

6 Ways to get More Bang for your Heroku Buck While Making Your Rails Site Super Snappy · Storm Consultancy 6 Ways to get More Bang for your Heroku Buck While Making Your Rails Site Super Snappy We love Heroku. It makes deployment so easy and quick. However, it can start to get pricey when you add additional dynos at $35 each a month. With a small amount of work, you can get a lot more out of your Heroku hosting whilst drastically improving the performance of your site. So how do we max out the performance of our Heroku apps? 1. By default a Heroku dyno is responsible for serving all the assets for your site, so every page load will involve multiple requests to the dyno. The asset_sync gem modifies asset pre-compilation to sync all of your assets to an Amazon S3 bucket from where they are served directly and freeing up your dyno to handle more requests. If you want to speed things up even more, you can slap Amazon’s Cloudfront CDN in front of your S3 bucket with multiple subdomains. 2. To prevent this from happening you need to decouple the upload process from your dyno. 3. 4. 5. 6.
