Software

Below is all software that I install when I get a new pc.

Windows Utilities

SlickRun : Starts programs quickly but what I especially like is hitting Win+j which pops up a small note taking utility that I use as a longer term clipboard.
KeePassXC: Password manager, if you're using Chrome I can also recommend using the Chrome extension.
f.lux: Automatically adjusts the colors of your monitor during the day to prevent eye fatigue.
7-zip: The best open source file archiver with a high compression ratio.
BareTail: follow log files
BareGrep: search in files

Development

Notepad++
Visual Studio + ReSharper
Visual Studio Code
R + RStudio
Python

GIS

Quantum GIS
gdal

Chrome extensions

pocket: In one click saving an url to read on my phone.
StayFocusd: Block procrastination websites while working.
AdBlock: Block excessive ads.
Tab Outliner: Crash resistant session manager, saves my life when Chrome doesn't restore my tabs after a crash.
Books

I might not read as much as fogus but I should start listening to his advice of keeping a record of what you've read. Below is a short selection of books I remember I've read AND that where really good. For the last years I've been keeping track of my reading (except comics) on GoodReads.

Programming & CS

Real World Functional Programming: With Examples in F# and C# by Thomas Petricek and Jon Skeet: This book really delivers on what the title promises. It starts gently but the last chapters are more advanced and challenging. Parts of this book can be read on MSDN.
Functional JavaScript: Introducing Functional Programming with Underscore.js by Michael Fogus: an introduction to functional programming presented in JavaScript, if you're totally new to the concepts of functional programming then it won't be an easy book but it's definitely worth the effort (my review).
JavaScript: The Good Parts by Douglas Crockford (he popularized JSON and wrote JSLint and JSMin): if you develop regularly in JavaScript then this book is a must read.

Other Non-fiction

Harry Potter and the Methods of Rationality by Eliezer Yudkowsky
Culture & Empire: Digital Revolution by Pieter Hintjes: Take a look on Amazon  or read my review.
The Art of Learning by Josh Waitzkin: The title says it all, a few years ago I wrote the following notes part 1, part 2 and part 3.
