When developing a program in Ruby, you may sometimes encounter a memory leak. For a while now, Ruby has a facility to gather information about what objects are laying around: ObjectSpace.
There are several approaches one can take to debug a leak. This discusses a time-based approach, where a full memory dump is generated every, say, 5 minutes, during a time that the memory leak is showing up. Afterwards, one can look at all the objects, and find out which ones are staying around, causing the
In this talk, I want to share my experience gained during the development of frontend applications in several programming languages.
I think it's not a secret for anybody that developing large JavaScript applications is not so easy as it seems at first glance. We all want something simpler and more reliable. Therefore, many developers and even entire companies switch to different, compiled in JavaScript, programming languages. The bulk of such transitions is accounted for TypeScript and flow, and often, developers faced with more problems than they were before.
I wasn't the exception. Moving to a new project, I started using TypeScript and was disappointed. Luckily in my next project I used ClojureScript and it was like everything is illuminated!
