What are the most useful gems to use in Rails?

ActiveModelSerializers s (which starts lagging while processingpound documents) and uses caching. Fast JSON API s . Fast JSON API wille in handy when you need fast serialization of software code.

Sounds like a question from the OS wars. To some extent it is. I will give you my personal opinion based on 25 years in IT. I have started with 8bitputers with BASIC went through MS DOS first versions of Windows Unix System V Solaris AIX HP-UX. At home I was running Linux since the early days. For 5 years I had a chance in working in apany where we have been developing software entirely on Linux. I waspiling my OS every night (using Gentoo for most of the time). Overall uX of systems got my attention and love. But at some point I was a bit tired of configuring my XOrg server for dual display fixing issues in printer drivers and network card drivers. There it came Mac OS X - everything great from the uX worldbined with flawless usage of peripherals great UI consistent with every next version (not line MS Windows after Windows 7) unix experience with great terminals (I use iTerm with ZSH and VIM as main editor) almost everything that I develop on Mac - works the same way on Linux From personal observation - MacOSX can be used from both IT Professionals and from people who do not have idea whatputers do. Many people will say that it is a closed proprietary OS running only on expensive hardware. For me - I would say that with MacOSX I feel free - to develop both for iOS and Android Linux Docker even Windows and to have the full unix toolset that I need. PS Recently Linux distributions have grown a lot - there are so few issues from the past. Microsoft have also started integrating linux toolset and unix like shells. But once running on MacOS X - rarely someone goes back.

What productive and interesting things can I do with my MacBook OS X El Capitan?
Well that depends now doesn it? At its core your MacBook (you don specify whether this is a MacBook Air MacBook Pro or 12-inch MacBook) is a fairly well-designed laptopputer running an operating system designed specifically for the hardware it has and you can buy applications and suites to add almost any functionality youre willing to pay for. Your Maces with Pages Numbers and Keynote so you have basic office functionality without spending anything more but if you want or need the full Microsoft Office experience that available at an extra cost. Similarly Photos and Preview offer you basic image and PDF editing abilities and if you need to go beyond that Adobe will gladly sell you a Creative Cloud license. If youre into databases you have your choice of open-source engines from the Unix world and if that learning curve is too steep you can buy FileMaker Pro. If youre into video games the Mac App Store has hundreds to choose from but if the one you want is Windows-only you can purchase Crossover install Windows on a virtual machine or use Bootcamp to run Windows natively on your laptop. To my mind the big advantage of using the Mac OS for my work platform is that it lets me be more productive and efficient with my time so I can do go other interesting non-work things some of them on a PC.
