my real objective is to reduce the amount of web that i browse. i'm hoping that the possibility of someone viewing a page and judging me for clicking on low quality ars articles or whatever will prevent me from doing so in the first place. also gamification w.r.t. amount of data transferred, time spent browsing, etc. i'm having a hard time coming up with a way to determine from stateless data how long a 'browsing session' as it were lasted, so if anyone has any bright ideas on that, i'd love to hear them. markov chains might be kind of interesting, though. what would be kinda neat would be to use the model created thus to continue browsing on my behalf so that anyone ostensibly monitoring the connection wouldn't be able to tell the difference.

just make it show a yospos indicator based on how much of your browsing is yospos or pos approved sites like apple.com.

so lets say i want to learn microcontroller stuff. i cannot program anything, i havent soldered anything since high school, and i have a very limited knowledge of electronics. but i've got a heart of gold, and a dream. do i: a) buy an arduino uno and use the arduino ide and its associated libraries? or b) buy an atmega32 and a programmer and use winavr? or c) kill my are self? i ask because, while i know arduino is much simpler, i feel like i'd learn a lot more and become a lot more proficient if i learned to live without it. my ultimate goal is to be able to learn smd and dfm stuff so i can actually build and design a device that could, theoretically, be mass-produced if i wanted it to.

depends, what are you trying to actually do imo its more important to Do the Thing in the easiest way possible, and if its actually cool and/or successful you could spend the time replacing the arduino with a purpose-built thing

Socracheese posted:depends, what are you trying to actually do i'm still stuck on the idea of a sous vide immersion circulator, which i raved about on this thread months ago. i guess, if forced to really set a goal, id say that id like to design and build one that cold be mass-manufactured. not really cause i want to sell it or actually mass-produce it, but because i find smt and dfm really interesting, at least from what ive learned of them so far.

you really don't need a book literally every command is on this page: http://arduino.cc/en/Reference/HomePage and the same site has everything you need to know about the ide (the program you code in is called the ide)

people seem unaware that for modern arduinos they solder on ISP (in-system programming/programmer) headers, so if you've got an arduino you've got an AVR dev board. you can do your project with an arduino and use the arduino IDE and whatnot to get it working, and then if you want you can rewrite your code in C and flash it on there with a cheapo AVR ISP. that way you've got a little AVR dev board that has a lot of sample code written for it, and if you need stepper motor controllers or wifi or whatever, but dont feel like designing your own, there are a fuckton of arduino-compatible boards to do all that poo poo that just plug into the arduino and have sample code available (which you'll have to tweak or probably rewrite if you want to use C, of course, but still). and the arduino IDE even has a menu item to reflash the arduino with the arduino bootloader (via an ISP), so if you flash it with something outside of the arduino IDE and want to turn it back into a vanilla arduino that's easy too.
