What are the most useful gems to use in Rails?
RubyGems were developed to simplify and accelerate the stages of the application creation deployment and library connection. Utilizing this package manager for Ruby saves you time as you get ready-made solutions to almost any task instead of writing the functions from scratch. Each gem contains a particular element of functionality including all related files.

How can I convert a PDF to Word?
There is no good way to use Microsoft Word to edit PDFs. Microsoft Word is used for authoring an original document not modifying a portable document. True Word can import some data from a PDF. That feature is useful when you are authoring a new document and wish to salvage data from a PDF to prevent time spent entering data. In that case it is best to import the PDF into a file by itself and strip it of formatting then copy and paste it into your pre-formatted document as Normal . Then you will proceed to make other formatting changes for headings section numbering etc. If you must edit a PDF directly your edits should be minor. Even in Adobe Acrobat DC Pro you are limited in how much editing you can do. Fix a misspelled word maybe replace a word here or there. If you try to rearrange a document or make edits that cause significant changes regarding allocated space you will not get what you expect. The way flows in a PDF is not always what you expect so shortening or lengthening paragraphs will give strange results oftentimes. PDF editors are not page layout programs. So if your edits are minor and you must edit the of an existing PDF get your hands on a PDF editor (not free). If you can get away with obscuring existing and s you just need good annotation capability. If you have a Mac you can use Preview to annotate or cut and paste graphics. The free Acrobat Reader allows some annotations too. You can use annotations to white-out a section of and put in new annotation to replace it. If you are careful it may not be that noticeable. You can white-out s to alter graphics. You can create a Frankenstein Monster of a document if you like using free PDF annotation software. But then youll ask yourself why you didn just make a whole new document in Microsoft Word something you could call your own.

What is your review of Kindle Paperwhite (2015 version)?
I belong to the grandfather style of reading books and for the longest time I believed that physical books was the only way to read books- books and others. I used to scoff at anyone using ebooks to study and read. But modern technology has a way to creep into our lifestyles. I was already using my iPad to read PDFs of scientific papers books and academic articles. But I was actively avoiding a proper e-book reader with e-ink technology for the longest time. That changed this July when my wife gifted me my first kindle- Paperwhite (215 ed.). I've been using it for 3 months now and I'm now a total convert. These are few of my observations The letters are crisp and don't look like digital font. I like the new Bookerly font though I've not used any other font topare in detail. The pages look and feel is paper-like. I would say I don't miss paper at all except for the smell of fresh books. Unlike my iPad which I had to charge every 2-3 days the paperwhite I only have to charge about once in a month. I use my kindle for about 2-3 hours a day. The front-light tech is awesome because you can read with the lights off and there in no glare at all. It is easier to sleep after reading from the kindle. Staring at bright screens causes your biological clock to go haywire ( Bright Screens Could Delay Bedtime ). Shopping experience on Amazon store is excellent. You can buy in mobileputer or directly from the are cheaper than paperbacks and most titles are available in kindle format. Subscribe to some websites like and and you'll get many free eBooks and good deals in many others. From my experience the good and latest titles are difficult toe by in the deal section. Calibre is a useful free software to convert all non-kindle formats to mobi or azw formats. I only have to just email any document directly to my kindle id and WiFi will automatically update my kindle library. One hack I've learnt is that no matter what format the eBook is in when you email the book to your kindle id putting convert in the subject line will convert it to azw format. I've tried it with PDF and epub and this is very useful since this way I don't need to use Calibre. The number of non-academic books I have read has increased since I started using the kindle. I average about 3 books a month now. Pre- Kindle I was more like 1 book in 6 months. The Kindle app is very useful to have in my smart phone and it serves me one specific purpose which I'll detail in my next point. Initially I was having problems for my academic purposes. All scientific paperse in PDF format and not in the kindle format. The direct PDF page rendering is a chore. The enlarging and pinch function of the kindle is not very responsive. when you convert PDFs to kindle formats the graphstables and figures go haywire. I have found a simple way around this PDF is converted to azw format the is more or less spared from any formatting if it is not a scanned copy. So I email the PDF file twice to my kindle id- once with convert in subject line and one without. So now I have both PDF and azw format in my kindle. There is simultaneous syncing of all files in the cloud. I read the from my kindle and look up the graphs and tables in my cell phone. This way I can spare the battery of my cell phone from draining out while I'm reading. I'm especially proud of this hack. In summary I'm a very happy customer. My reading has increased-both academic as well as non-academic (fiction and non-fiction). I'm hardly using my iPad now and the kindle along with some support from my cell phone is doing the job for me. Generally over the last several years my online consumption of information has greatly increasedpared to printed material like newspapers magazines books journals etc. This has been possible because of the many news & magazine apps digitization of even academic content and improvement of internet. So now it is cheaper convenient and more efficient to access information. I think embracing new technology like the Kindle is the way to go! PS I do hope Amazon is working on making PDFs a little better reading experience than it is now.
