Posted in How ActionCable Uses Redis Discussion

Nice! I d like to see an episode on ActionCable & Redis tuning and optimisation to allow massive number of subscribers (100+) with frequent updates. Im currently pushing matrix with data of size 800*50 each few seconds and struggling to have more than 100 subscribers, as it starts lagging

Posted in Push bitmap to clients in realtime

Hi Chris!

I want to create a service which will show a heatmap with some stocks data in realtime (updated each second). Each second there will be around 100 new data points and in general, chart may contain up to 30 000+ data points. Do you think that creating separate process for data connector (e.g. http://michalorman.com/2015/03/daemons-in-rails-environment/) and pushing data through redis (action cable) to rails application, where .js will generate bitmap is optimal way to go? (https://neil.fraser.name/software/bmp_lib/). Or is it better to let js fetching data directly from the browser?

Posted in Using Purchased Themes with Rails | GoRails - GoRails

Another way to get purchased theme working in minutes is to create subdomain specifically for serving assets, e.g. assets.domain.com. Then configure your server (Nginx, Apache) and add new server block, pointing to your local directory with theme files. I use this approach for sites, where I have mostly static content (e.g. one-pagers), with couple of dynamic features: contact us form and news section.
