For the sciency folks out there, some of these may come in handy:
R - A stats program that has exploded in popularity and usage over the last five years. It's based upon the program S+ and is a command line style analysis software. The base program as well as many add on packages and IDEs - I personally find
R Studio to be one of the best and most widely used. I'm still very much a beginner at using R as the language itself has a bit of a learning curve. However, just with my limited use I've already experience how powerful this program is and the wide range of things it can do. I feel that another few years and R will definitely give SAS a run for it's money and probably leave SPSS in the dust.
Python - This is technically a programming language although some folks disagree and call it a scripting language but I think it's just a to-MAY-toe/to-MAH-toe kind of issue. The language is actually fairly intuitive - as programming languages go - and it offers an immense amount of different applications you can use it for. A lot of people in the analytics world are finding a lot of use with it especially in machine learning uses and also as an accessory to already established statistical programs like R and SPSS. Python also has a ton of IDEs available, the one I use and I see often is
PyCharm by JetBrains.
Sublime Text Editor - This text editor has programmers, script writers and command line program users in mind. It is set up with a bunch of preset language syntax environments such as SQL, R, C++, Java and lots more. So you can write your code in the editor, debug it and change it around and write multiple languages separated by tabs just like on the internet browsers.
Oracle SQL Developer - If you have any interaction with databases you'll most often run into Oracle's products - they are one of the big dogs on the block in that area. I found their SQL Developer extremely useful and helpful while learning SQL and making use of databases constructed in Access.
SAS University - If you have an email linked to an institution of higher learning - aimed at mainly college students and instructors, SAS offers a free version of their software based upon their SAS Studio version of SAS. SAS has been around a really long time and is the top of the food chain as far as statistics software is concerned.
Mendeley - If you do a lot of research, you collect documents and end up with a massive amount of them. It can be hard to organize them and that's where this software comes in. It helps organize your references and PDF documents to make it easier to find the info you need in your own literature library.
And an extra for the musicians:
Pro Tools First - Pro Tools is THE name is digital music recording and engineering. Now they offer a free version of their famous software. Gone are the days of trying to get a great engineered sound from Audacity - now you can have something that was specifically designed for recording music, for free.
