People have allready recomended many excellent books...
Now if you are going to drag any deadweight electronics there, make sure you bring in means to charge them too. Laptop with empty battery is useless.. So solar-panel or two (bigger the better), inverter, battery and battery charge manager.. And you can charge what ever western not needed electronics use you have...
Personally i would look what it-related projects are already there and try help them. Working with actual people will always be superior to any dull book. In fact if you can show that you have managed to come along even with people that you have no common language, might help your career more then any book.
If all else fails, just enjoy scenery and piece of quiet you have there, your soon enough back to civilization and hurry..
