This is my default career advice for people starting out in geo/GIS, especially remote sensing, adapted from a response to a letter in 2013.

I'm currently about to start a Geography degree at the University of [Redacted] at [Redacted] with a focus in GIS, and I've been finding that I have an interest in working with imagery. Obviously I should take Remote Sensing and other similar classes, but I'm the type of person who likes to self learn as well. So my question is this: What recommendations would you give to a student who is interested in working with imagery? Are there any self study paths that you could recommend?

I learned on my own and on the job, and there are a lot of important topics in GIS that I don’t know anything about, so I can’t give comprehensive advice. I haven’t arrived anywhere; I’m just ten minutes ahead in the convoy we’re both in. Take these recommendations critically.

Find interesting people. You’ll learn a lot more from a great professor (or mentor, or friend, or conference) o

After installing Arch on my Raspberry Pi, internet worked out of the box: I could plug it into the router, turn it on, ssh in and start downloading things. But the router is in my housemate's bedroom, which isn't ideal. If I want the Pi to be connected to the internet in my room, I need it to be connected to my laptop. (Another option would be a USB wifi dongle, of course.) This is how I did it. Much credit goes to the Ubuntu wiki's Connection sharing page.

I should disclaim that I don't fully understand networking stuff, and some of what I say might be wrong. I also didn't write this as I was going; so while I've consulted my browser and shell histories, it's possible I've forgotten some steps.

My laptop is running Gentoo, and this is where most of the work has to be done. It connects to the internet through wifi, on interface wlan0. The ethernet port is eth0, and eth0 is also the name of the ethernet port on the Pi.

Step zero: plug ev

G-WAN is a new free web server. They seem to be very proud of it, or at least just want to make a lot of money. Well anyway, in almost every sentence they write, they claim that they are 20% cooler than anything else. It feels a bit arrogant. I have to admit, I don't know a lot about web servers, so I can't speak to how good they are.

However, then I saw their Captcha example. I also don't know much about machine learning algorithms, OCR, and stuff like that, but I do know how to read pixels. I also know how to compare values with python :P

They say the following about their Captcha:
