How We Moved Rails Development to Windows WSL2 Linux

July 29, 2020

Up till now we had been developing Rails 6 applications on linux using VMWare on a windows laptop. But now with the general availability of WSL 2, we can retire the old laptop and do everything together in one place. Given that WSL 2 does not currently support GUI applications, we cant expect to replicate the Pepermint distro that was so nice to use. Instead we are taking the opportunity to retool to use VS codeOur toolset uncludes “Git”, “Rails”, “PostgreSQL”, and deployment to “AWS Beanstalk” ... Read more

Ubuntu running low on disk space

June 11, 2016

Warnings have been popping up with increasing frequency that the disk space is running low on Ubuntu running on VMware Workstation 12 Player.

Scaling down to single instance Elastic Beanstalk.

Elastic beanstalk is handy for provisioning and deployment, and thankfully the load balancer is not compulsory. ... Read more

February 23, 2015

Recently we embarked on a new feature requiring a gem that is not compatible with Windows. see also: [Moving Rails Development to Windows WSL 2 Linux] (/post/moving-rails-development-to-windows-wsl2-linux/). To re-quote a quote from : “The reality is that Ruby, as used by most Rails apps is full of unixism, performance of Ruby MRI (the default Ruby) on Windows is abysmal, Rails load times are hellish, sooner or later (more likely sooner) you are going to hit gems that simply do not work properly on Windows. ...

Deploying versions with zero downtime

July 24, 2014

Two months, almost to the day since we last hit problems with deployment, it looks like we are here again. Up till the day before, deployments worked fine if a little slow, but now they fail with a timeout. The site is running okay but remains at that version: It is not possible to retrieve the logs - also due to an execution timeout. It is possible to SSH to the EC2 server but looking around the logs it appears everything is rolled back. ... Read more

Bootstrap-sass upgrade for Rails on AWS

June 5, 2014

We recently spent a little time replacing blueprint with twitter bootstrap - precompiled with sass. It looks great. When it came to deploying to Elastic Beanstalk, we hit a few unexpected issues. Here is what we did to get it working. We are running on the 64bit Amazon Linux 2014.03 AMI. The up to then prerequisite nokogiri v 1.6.1 gem was already installed and working fine. The problem came with bundle install requiring nokogiri v 1. ... Read more
