How do I install a PDF editor in Ubuntu 16.04?
You don really need to install a PDF editor to edit most of your PDF documents on Ubuntu. Ubuntues with the LibreOffice suite. Using LibreOffice Draw you can import and edit PDF documents. In case LibreOffice Draw isn what youre looking for there are plenty of PDF editors available for Ubuntu I prefer to use Master PDF Editor. Open Terminal using CTRL + ALT + T and give the belowmands wget code sudo dpkg -i master-pdf-editor-*.deb code The first line would download the installer for you while the second line would install it. In case you face any issue during the installation especially unmet dependencies run the belowmand sudo apt -f install code Thanks for the A2A italic Muthu Anand italic user 2759425 -) italic
Can Linux become an everyday system like OS X or Windows?
A couple years ago I decided that I was going to go down the Linux is my only desktop road. So before I jumped fully in I installed Ubuntu in a virtual machine on my Mac and tried to run it exclusively for everything. Email entertainment etc. It was aplete bust. I was extremely used to the conveniences that OSX provides. There wasn shit out there for email clients that also integrated with a calendar. There were a lot of options but they all sucked bad. I spent HOURS trying to get things set up like I wanted which admittedly was what I was used to on the OSX clients. And just stop it before you say just use the browser for gmail and calendarit doesn work for me and I hate their interface. Oh and install a printer or any other peripheral? Pffftget ready to search and search for obscure drivers that you have to COMPILE and may just never work. And if you need to use the microsoft office suite youre just SOL. Open office is fine if everyone else uses open office otherwise youre screwed. I LOVE Linux. I really do. Ive developed on Linux for almost 2 years and am pretty handy at administering servers if I do say so myself. But as an everyday system? Forget about it. Not even close unless you adjust your expectations and have a ton of time on your hands. I remember hearing people say that Linux has finally be a full fledged system that can replace Windows 1+ YEARS AGO. It wasn then and it not now (at least for me). Will it ever? Im not sure and I don really think I care that much. Can it ever? Sure as long as someone puts a ton of support and money behind it. If youre a casual user who only browses the internet and checks your email account sure it fine i.e. chromebook. But need to do anything more than that? Good luck!!

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. Unfortunately they aren structured in any way so in order to find ruby gems it better to use a regular search engine and the required key words (check GitHub s ). Our dedicated development team also actively employs Ruby Gems in the process of software development. Here is the top of the most popular and useful ruby gems according to our experience GeoCoder s . Being able to connect through itself over 4 APIs this Ruby gem implements both the direct and reverse geocoding by IP address geographical coordinates and even real physical addresses (e.g. the address of the street). Bullet s . The most downloaded Ruby gems out there. It was initially created with an intention to boost software performance. It does so by decreasing the total amount of client-server requests. Basically Bullet tracks the N+1 cases of requests and notifies the developer when other tools can be used instead (e.g. cache counter). Pry s . We rmend to simplify the bug fixing procedures for your RoR-based application with the Pry gem which is a more advanced alternative to the standard IRB wrapper. 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. It works much faster than Wicked PDF s . This gem is working alongside with wkhtmltopdf s and helps realizing an interaction with the DSL generator. Devise Masquerade s . This Ruby gem helps developing multi user apps. In particular youll be able to test your app from the perspective of users with different levels of access. Devise s . Based on the MVC model the Devise gem can provide secure user authentication and session management. Letter opener s . If you need to create a newsletter mechanism to send notifications to all users that launched your app this gem will help you do that much easier you won need to integrate and configure your own SMTP server. Money Rails s . If you are planning to integrate your app with Ruby Money this gem wille in quite handy. Pundit s . A tool that allows defining different levels of access to the app functionality according to the rights of an authorized user.
Why is the content of a PDF in a weird language when I open it with notepad?
Thanks for A2A. Raw Postscript is mostly human readable. It is primarily a language based on FORTH. The problem that you face when looking at a PDF file in notepad is that it automatically breaks multi-byte characters into individual 8-bit characters. However because of the way PostScript initially handled extended characters even ue7 should be identifiable by the presence of the c and the although I can guarantee this in the days of Unicode. Back in the DOS days MS Word sent a large header file ahead of a document in order to teach a PostScript printer how to understand its own pre-PostScript MSPrint language that was written with the foresight italic of scalable fonts and the anticipation of outputting to Lino machines. While that header file was rather iprehensible at a glance the actual MSPrint generated document could be loaded back into a editor and the of the original document could be extracted for reconstruction purposes. Admittedly if the persons behind converting PostScript to MSPrint had written a direct italic PostScript driver instead the memory overhead on a PostScript printer would have been significant reduced. Imagine that you have an ancient 8-bitputer that runs BASIC on start-up and w ithin that BASIC you wanted to write a new a program that could run C++. That is what the original header file did to a PostScript printer. Admittedly the PostScript printer driver that shipped with DOS Word was only capable of using the inbuilt fonts and was limited to whole-point sizes. A proper PostScript font is also written in the PostScript language so that new fonts can be downloaded to the printer if they aren already present. While the PostScript language and interpreter were extremely well written the emergent fonts were not. Instead of relying on PostScript ability to draw stretch and distort a basic circle (or any part of the arc of that circle) along with the ability to trace a precise curve according to a mathematical equation many writers of pre-Windows drivers only relied on the line-drawing ability and a circle (or other curve) would be defined by multiple lineto italic mands and neer an arcto italic mand to be found. This resulted in jagged edges which were obviously visible even in fonts particularly when enlarged. PostScript was originally only written to handle black & white and gray shading was aplished with varying sized dots much in the same way that an old newspaper photo was created. There was a specific protocol for downloading bitmap of the font in that size. As each character is required for printing it copies the bitmap into place. When you change font size this process is repeated for the new size. Unless it is short on memory the printer will generally retain these bitmap renditions until it finally receives the EndDocumentmand or it may discard an older bitmap rendering in favor of the current one. Windows uses its own pseudo-PostScript italic language for handling fonts and scaling. When you print a page the output is generated in this pseudo-language which is then translated directly to bitmap form by the selected Windows printer driver. The same applies to generating a PDF file. The Windows pseudo-language must be translated to real PostScript so that a PDF viewer can read it. To aplish this Windows often inserts bitmap renderings of fonts in the desired point-size. Originally there were three basic file s for PostScript. A font file a PDF (Portable Document Format) file and an EPS (Ecapsulated PostScript) file. An EPS can be considered as equivalent to a single PostScript character even if it contains a massively detailed graphic. This can be placed anywhere on a page and scaled up or down in size and the Printer takes care of the rest of it. While .ps and .eps files haven changed drastically PDF has. Instead of being just a PostScript language copy of a document that can either be printed or viewed it has evolved into an interactive document of its own. That is why you can fill out PDF forms before printing. Some of these forms are soplex that selecting one option can create or delete an otherwise hidden but section of the document. As I pointed out above the majority of these PDFs will have been generated by Windows. Ever since the DOS days when No one will ever need more than 64kB* MS has been rather sloppy in its coding. If you take the ever so standard first program that people wrote on their home machinesn* Often attributed to Bill Gates although he denies ever having said it. 1 CLSn2 PRINT HELLO WORLD It takes up almost no space in source-code form. When put through a BASICpiler you end up with 5kB+ exe file that is full of unreferenced DOS-error handling routines that would still be handled by DOS rather than your original program. This same sloppiness applies to Word. Create a single paragraph and export it as HTML. The output will be reams of unnecessary material (where my original paragraph in all of that!?) when a good HTML writer could do the whole thing from scratch resulting in something only slightly larger than your original paragraph. While PostScript as a language attempts to retain its human-readability PDFs generated via Windows (and probably later versions of MacOS) will generally have iprehensible headers and extraneous material because no one knows how to write tight code anymore. Further if the OS were tightened down to bare-bones code the application italic used to create the source of the PDF could still be inserting its own unnecessary material.
