Here are my recommendations for software solutions that might increase your productivity, improve your product quality, and save you tons of time and money. My philosophy is to use software that is high quality, reliable, secure, multi-platform, and cost-effective. Your feedback and suggestions are welcome. User-friendly programs have an asterisk (*). Enjoy ...
Life / Time / Task Management
Org-mode (http://orgmode.org/) (for Emacs users)Org-mode is an Emacs mode for keeping notes, maintaining ToDo lists, and doing project planning with a fast and effective plain-text system (GNU Emacs is a text editor---see below under Text Editors). Org-mode develops organizational tasks around NOTES files that contain information about projects as plain text. Visibility cycling and structure editing help to work with the tree. Tables are easily created with a built-in table editor. Org-mode supports ToDo items, deadlines, time stamps, and scheduling. It dynamically compiles entries into an agenda. Plain text URL-like links connect to websites, emails, and any files related to the projects. For printing and sharing of notes, an Org-mode file can be exported as a structured ASCII file, HTML, and PDF LaTeX.

Task Coach* (http://www.taskcoach.org/)Task Coach is a simple open source todo manager to manage personal tasks and todo lists. If you don’t use Emacs, try Task Coach. Price = $0.
Computer Operating Systems
Ubuntu Linux (http://www.ubuntu.com)Ubuntu Linux is an open source operating system based on Debian Linux, and is the clear choice if you want excellent functionality, reliability, and security at an very affordable price. You can convert your old MS Windows computer to Ubuntu Linux, or purchase a computer with it pre-installed (e.g., System76). Linux is an affordable alternative to Mac OS (also Linux-like). For the average workplace and home, Ubuntu Linux will have everything you need (including hundreds of free software solutions). For a limited budget, Ubuntu Linux is the clear choice.
Here is a screenshot of Ubuntu Linux on a System76 computer. On the left upper corner is GNU Emacs running AUCTeX; Gmail on the right upper corner; and Terminal on the lower right corner.

Mac OS* (http://www.apple.com)Mac OS X is an alternative choice if you want the functionality, reliability and security of Linux combined with the popularity of Macs. After many years of dissatisfaction with Windows, I had switched to the Mac OS, and I have never looked back. Mac OS X is a derivative from the FreeBSD operating system (originally from UC Berkeley!) with lots of open source (free) tools/software (although not nearly as many as Linux). If you are comfortable with Macs you are one step away from moving up to Linux. (Personally, I find Ubuntu Linux much more user-friendly than Macs. Unfortunately, Apple has become much more “closed” and they lock you into their “ecosystem.” So, I no longer used Macs at all. However, Macs are a still significant improvement over Windows!)
Integrated Office Suite
LibreOffice* (http://www.libreoffice.org)LibreOffice is a free, open source, Microsoft Office-compatible and cross-platform (Windows, Linux, Solaris, and Mac OS) productivity software suite that includes a word-processor, spreadsheet, presentation program, and relational database, comparable to Microsoft Office’s Word, Excel, PowerPoint, and Access. OpenOffice can read and output these MS Office files (I have not used MS Office products since 1997). It also includes editors for HTML, drawing, and math equations. LibreOffice exports to many formats, including Portable Document Format (PDF) and LaTeX. LibreOffice.org output is of the highest professional quality and gives you the most flexibility in making your work available to the widest audience worldwide. At home, we only have and use LibreOffice. Price = $0.

Google Chrome* (http://www.google.com/chrome)Google Chrome is a web browser designed for speed, simplicity, security and much more: search, chat, email, shop, bank, read the news, watch videos online, etc.Price = $0.
Mozilla Firefox* (http://www.mozilla.com)Mozilla Firefox is an open-source web browser designed for standards-compliance, performance and portability. Firefox is an award winning preview of next generation browsing technology from mozilla.org. Firefox empowers you to accomplish your online activities faster, more safely and efficiently than any other browser, period. Built with Tab browsing, pop-up blocking and a number of other seamless innovations, Firefox stands out ahead. Price = $0.
Read about R in the New York Times.

RStudio* (http://www.rstudio.com)RStudio is a free and open source integrated development environment (IDE) for R. You can run it on your desktop (Windows, Mac, or Linux). Install R first, then install RStudio. This is the dream IDE customized to running R. RStudio is for newbies and experts alike. You will not be disappointed. Price = $0.

GNU Emacs (http://www.gnu.org/software/emacs)GNU Emacs is an open source, extensible, and powerful text editor. Absolutely the best! My clear favorite for R programming, editing (text, HTML), and preparing technical documents using LaTeX. For Mac OS, I recommend the modified Emacs for Mac OS X with AUCTeX, Emacs Speaks Statistics (ESS), and much more. Also consider Aquamacs Emacs --- an easy-to-use, Mac-style Emacs for Mac OS X. For Windows OS, I recommend the Emacs/AUCTeX bundle; however, you will need to add ESS. For Ubuntu Linux, I prefer the Emacs meta package which is available from the package manager. Price = $0.
Here is a desktop screenshot of GNU Emacs running Emacs Speaks Statistics (ESS) and R (left), and an R plot (right).

Portable Document Format (PDF) manipulation
pdftk --- The PDF Toolkit (https://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/)pdftk is a command line program to merge, delete, burst, rotate pages from PDF documents — and much more! Please do not purchase expensive PDF manipulation software! Price = $0.
Photo & Image Editors
GIMP* (http://www.gimp.org)GIMP is the GNU Image Manipulation Program. It is an open source program for such tasks as photo retouching, image composition, and image authoring similar to Adobe Photoshop. I use the GIMP primarily for cropping and rescaling images, converting images (e.g., TIFF to EPS, etc.), and creating images for the Web (e.g., PNG). This is the only image (including photos) editing software you will ever need. Price = $0.
Inkscape* (http://inkscape.org)Inkscape is an open source vector graphics editor, with capabilities similar to Adobe Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format. Inkscape supports many advanced SVG features (markers, clones, alpha blending, etc.) and great care is taken in designing a streamlined interface. It is very easy to edit nodes, perform complex path operations, trace bitmaps and much more. Price = $0.
ImageMagick (http://www.imagemagick.org)ImageMagick is an open source software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. The functionality of ImageMagick is typically utilized from the command line. Price = $0.

Freeplane* (http://www.freeplane.org/)Freeplane is a multi-platform (Linux, Mac, Windows), free and open source software to support thinking, sharing information and getting things done at work, in school and at home. The core of the software consists of functions for mind mapping, also called concept mapping or information mapping, and tools for using mapped information. Freeplane runs on any operating system on which a current version of Java is installed and from USB. Freeplane can be used to prepared papers in LaTeX, and is the core of an academic literature suite call Docear (http://www.docear.org). Price = $0.

LaTeX (http://www.latex-project.org)LaTeX is a high-quality typesetting system, with features designed for the production of technical and scientific documentation, especially that involving mathematical notation. LaTeX is the de facto standard for the communication and publication of scientific documents. For Ubuntu Linux, just install Texlive using the package manager. For Mac OS, I recommend the MacTeX Texlive distribution. For Windows OS, I recommend the MiKTeX distribution. Price = $0.
If you are new to LaTeX, see my tutorial LaTeX for Public Health and Medicine.
AUCTeX (http://www.gnu.org/software/auctex)AUCTeX is an open source, extensible package for writing and formatting TeX files in GNU Emacs. It supports many different TeX macro packages. AUCTeX includes preview-latex which makes LaTeX a tightly integrated component of your editing workflow by visualizing selected source chunks (such as single formulas or graphics) directly as images in the source buffer. AUCTeX makes creating LaTeX documents easier, fun, and error-free. Price = $0.
JabRef (http://www.jabref.org/)JabRef is an open source bibliography reference manager. The native file format used by JabRef is BibTeX, the standard LaTeX bibliography format. JabRef runs on the Java VM, and should work equally well on Windows, Linux and Mac OS X. I use JabRef to search PubMed, and import and manage references. As a bibliography manager, JabRef is clearly superior to EndNote. If you don’t use LaTeX and/or BibTeX, you don’t need JabRef. Price = $0.
