What are the most useful gems to use in Rails?
There are many gems to consider. The following article from RubyGarage is a comprehensive overview of many different gems, 57 Best Ruby Gems We Use at RubyGarage.If you’re looking to implement analytics, I’d also recommend checking out Segment and adding our analytics-ruby gem. Segment is a flexible solution for tracking user activity in any system. Segment provides a single API for you to send track calls that describe user activity.Our library will collect user activity that you send to Segment, and then transforms and forwards those events to any connected destination (we have hundreds of tools to choose from).To get a bit more insight into the implementation, I’d recommend looking at the following tutorial Thoughtbot created on implementing Segment into your Rails application.Hope this helps!
Is there an app for both Mac and iPad I can use to quickly read and highlight PDFs?
On a Mac you can just use Preview, which comes with the system. I don’t have an iPad but if I did I’d probably buy PDFpen, which I also use on the Mac, but note that it isn’t cheap. PDF Editor for iPhone - PDF Editor for iPad | Smile Software

What is the best free non-Adobe Mac OS X app for editing PDF files?
I really like using neu.Annotate+, which allows me not only to read, but take nots on the PDFs and send them directly via email in multiple formats. Note taking includes hand-written mark ups, typing in text, various colored pens and highlighters, and the ability to add images as well.
What is the best free PDF editor for iPhone?
The editor I'm suggesting isn't necessarily iPhone specific, however it will work great on that device! PDF Pro (https://www.pdfpro.co/) is a free tool that allows you to edit, convert, and create PDFs. If you use it 3 times or less a month then it will be completely free. If you use it more, there are inexpensive pricing plans available.Personally, I like that it's not an app that is taking up space on my phone. I just saved the site link in my bookmarks for when I need to use it.It's super easy to use, hope it works for you too!
What are the best Mac-only applications?
As a person going into academics - the top programs you have to look forward to (by so far) are:Latexian - LaTeX editor / autocompletion / live preview, there is no equivalent for WindowsOmniGraffle - can make basically anything, from circuit diagrams to basic flowcharts, there are good ones for Windows, but not reallyVersions - subversion client - but they do this incredibly well, there is no equivalent for WindowsFaceTime - video chatting, Skype is the obvious equivalent, but I feel FaceTime has a better video-chatting qualityCyberDuck - this is an FTP/SFTP/everything client (also connects to AWS and Dropbox and the like) so it's a nice all-in-one. It still has features to be desired, closest equivalent might be WinSCP or FileZilla.TextWrangler - this is the equivalent of Notepad++ except that it works a lot better with automatically-updated files like Dropbox (it auto-refreshes your files) and has a streamlined way of switching between files you're editing, the closest equivalent for Windows is Notepad++.On a related note - within Physics - a significant amount of professors and graduate students use a Mac so being able to share files, screen-sharing, and FaceTime is so much better when everyone is using it.
What are some very useful but not so popular iOS apps?
VizzyWig 2017: It's the priciest camera app in the app store, it has lot of controls to fine tune photography & videography but its USP is something completely different. When this app is installed on iPhone SE, 6S, 6S Plus, 7 and 7 Plus then it lets you record 5K videos on them, something no other mobile phone can do.Wondershare PDFElements: This app is a PDF editor for iOS, and by PDF editor I mean a real full fledged PDF editor, not like those stunted and crippled ones like Xodo PDF, Nitro PDF etc. It lets you edit or delete text in pdf, reposition images, add or delete pages, has scanner with OCR technology, sign documents, fill forms etc. It's literally like a Adobe Acrobat Editor in your pocket. Now many of us think that who needs a full fledged PDF editor on his phone, but believe me this app is indeed quite nifty to make last moment edits in your PDFs.Pixelmator: When we think about photo editors for phones we often think about Adobe Photoshop Elements or any other editor which essentially have nothing more than few curve adjustments, brightness & contrast adjustments and few filters. But how about having an advanced raster graphic editor on your phone, well if you are one of those few who crave for an advanced graphics editor with layer support, brush tool etc then Pixelmator is the best tool for you.xkcd-Open Source: It's an open-source xkcd client for iOS and hands down the best xkcd client for iOS. As of xkcd comics, well they are indeed quite funny with witty remarks about scientists, engineers. computer programmers etc.YACReader: The abbreviated name for “Yet Another Comics Reader”. It hands down the best comic book reader for iOS and it’s also available for Mac & Windows. The best feature of this app is to keep your comics synchronised between your iOS device and your Mac or Windows PC. It’s UI is beautiful (the only comic book reader I’ve seen with better UI is the Cover Comic Book reader but it’s a UWP app, available only for Windows 10 Mobile & PCs)
