For the past year, I’ve been working mainly with AngularJS and before that Ruby on Rails. I’ve never heard of Meteor until a few weeks ago. I am intrigued by the idea of tightly connecting the client and server together in a synergistic manner that allows for fast responsiveness, which is what Meteor is all about. I decided to go through Meteor’s tutorial online and get a feel for why the framework differentiates itself from other current technologies. From a very high level perspective, Meteor is a very good solution for quickly building an application from the ground up and provides some cool features out of the box.
Over the weekend I made performance optimizations to an internal web app that we use for time tracking and invoicing. The app runs on tomcat and is built using grails 2.4.2. Grails 2.4 included some major changes including asset pipelining. This is the first time I’ve tuned a grails app, and I had to do quite a bit of web crawling in order to find my way. I thought I would share some of the helpful tips I encountered, parts of the configuration I used, as well as some dead ends that could waste your time.
Heroku is one of those really great tools to help you get started fast with hosting. They support a variety of stacks and save you blood, sweat and tears when it comes to deploying an app. But what about those times where you need to mess with filesystems or have custom binaries that you want to run? How about just having more control of your servers?
As a consultant, approaching new code bases is something that happens every day. As exciting as it sounds however, working on many different projects can be really tough. This is because in many occasions we are not provided with all the details that we need, but we just requested to fix something that is broken.
What makes these tasks difficult is that the data and code structures can be very large and not very intuitive. Also, it might not be clear who holds the knowledge on them, or in some cases the knowledge can be even lost; for example being held by people who left the company.
Recently, I had the opportunity to work on an exciting in-house project for Grio called Filedart. This service, which will launch in the near future, affords the denizens of the web the ability to effortlessly upload content to the cloud by dragging photos or files to a small icon in their taskbar. After the file is uploaded by the client, the service automatically copies a mini-fied URL to the client’s clipboard. This URL leads to a brand-new, public web hosting wrapper for that file that they can easily distribute to their friends of colleagues to share. The service is free, and users don’t even have to log-in to use it.
Google’s AppEngine is a very useful platform in the way it allows developers to have an application server up and running within 10 minutes.
It leverages the Google infrastructure, too, offering high speed, high capacity, etc.
However (Hmm), AE does not allow for the usual multi-threading mechanisms…
What is Capistrano?
Capistrano is an open source tool mainly used to deploy web applications from source code management (SCM) to one or more servers. The aim of this guide is showing how to easily deploy your app to amazon EC2 using Capistrano. We can leverage its multi-stage extension to provide a different deployment strategy in different scenarios.
What’s Amazon DynamoDB?
DynamoDB is one of the most recent services offered by Amazon.com. Announced on January 18, 2012, it is a fully managed NoSQL database service that provides fast and predictable performance along with excellent scalability. Let’s quickly analyze its positive and negative aspects in the lists below:
Solr is an open source enterprise search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, rich document (e.g., Word, PDF) handling, and geospatial search. Solr is highly scalable, providing distributed search and index replication, and it powers the search and navigation features of many of the world’s largest internet sites.
