What programming language should I learn in order to freelance?

This Fall I will be starting a PhD in the social sciences. Because of my research interests/subfield, I will have to know the ins and outs of statistical software like R, Stata, and SAS. Can this knowledge enable me to freelance for some supplemental income or should I being learning another programming language? [more inside]

Help a programmer take care of her eyes, please.

I just started my first developer job. I squint at the computer screen all day. By the end of the day, my eyes are red and bloodshot. I can't deal with small text, but I can't make it all bigger - for instance, I can change the size of the code in my IDE, but not the debugger. I've reduced the brightness of my monitors dramatically. The only time my eyes don't hurt is when I'm so absorbed in my work that I don't notice. By the end of the day, I don't want to focus my eyesight on anything; it's even killing me to type this. Even watching tv bothers me. I seriously don't know how to take care of my eyes. Can you please offer some advice, and even give me a few horror stories about what happens to people who don't learn to take care of their eyes? [more inside]

developing a new document format: how to start?

i have a need for a new document format. This document format would be novel, bringing together various kinds of media (text, code, vector and raster image formats, and maybe others) together in one container. These pieces would all have specific relation to one another, as defined by the creator of the document. I know that no document format exists to do what I want to do, and I'd like to develop it - by myself, at first, until I get a handle on the basics of the problem. [more inside]

Please explain to me how Drupal's API works

I'm trying to build a form in Drupal 7 using examples like this but all I've been able to figure out is that I make my own module and... then what? How does the module actually become a form? I feel like I'm missing some huge part of the concept here and Drupal's documentation is either too simple or too advanced. What am I not getting? Thanks MeFi! [more inside]

What's the deal with programming author Yashavant Kanetkar?

This comment in a Hacker News thread introduced me to Yashavant Kanetkar. Apparently his C programming books are the worst of the worst. Yet somehow, the Indian education system uses his books pervasively. I tried to find out more about this guy and the controversy around him, but web searches turned up a flat nothing. Anyone read his books or know about the story?

How to store mathematical expressions as binary tree objects in Python

For a project, I need to store mathematical expressions as binary tree objects in Python, with each operator or operand being stored as a node. But I'm having trouble wrapping my brain around it; partly because this is my first real dive into the object-oriented pool and the specific nuts and bolts seem a little bit out of my reach.

How can I practice coding? (PS How can I tell if I suck at it?)

I'm pretty much a Kindergarten level Python learner. Basically, I'm on Exercise 41 in Learn Python the Hard Way (and confused), and I'm in a 100-level class learning Python. I am not a math person, although I do like formal logic (if that means anything). My biggest problem is that I think I try to solve problems too creatively, i.e. I always try the most complicated/convoluted solution possible, which is usually wrong. [more inside]

How do you know if you are a good programmer?

I was a comp sci major in college. That was 12 years ago. I graduated and as careers often do, I never programmed seriously again since... until now. I've spent the last 2 years teaching myself LAMP and jquery. It was like riding a bicycle. The data structures theory and other small things I managed to retain from my comp sci courses proved useful and in a very short amount of time I was able to rebrand myself a programmer. It's much easier and faster to create powerful, useful software these days than it was 12 years ago. Thing is though, and I imagine a lot of developers do this, the internet has made me more of a code aggregator than a programmer. I have 4 windows open at all times: coding window, app window, the jquery API and stackoverflow.com. Whatever I don't know how to do, I find very quickly on stackoverflow. I copy and paste the code directly and modify it as needed. Done. But I want to be better than that. I follow the general rules of good programming practice as much as I can... don't repeat yourself, be efficient, make your code neat, clean and easy to read. Without having a mentor or a guru around you, how would you know whether or not you are a good programmer or if you are a total hack???

Arduino time alarm without an external interrupt alarm pin on the RTC?

I want to program my Arduino to go to sleep at 6 pm and wake back up at 5 am, and then execute a few simple functions once every hour while it's awake. I have a DS1307 real-time clock, but it doesn't have an alarm interrupt pin, so I can't just set up an external interrupt to tell the Arduino to wake when the alarm pin is set to high. What's the best way to do this without an alarm pin? [more inside]

I need to learn the basics of APIs

I'm a web developer who is very capable with HTML and CSS, but that's about it. I am fairly comfortable with SQL, but now I need to learn to develop an API. I'd like to read a good book on the subject. Is there such a book? All I can find are things that explain why an API is useful, or things that assume you already know what you're doing in order to build/use an API.

PHPFilter: Need to sort array in a weird way - help

I have an array which has listing information for products on a website. The products fit into two categories (call them 'bits' and 'bobs') I need to sort the array so that it goes from a completely mixed up and randomized list to: bit, bit, bit, bit, bit, bit, bob, bob, bob, bob, bob, bob, bit, bit, bit, bit, bit, bit And so on, basically reorganize the array so that the list is in alternating groups of six Array structure is basically a numbered array of keyed arrays, like so: Array ( [0] => Array ( [id] => 39549 [title] => Product Name [author] => Author Name [price] => 7.66 [type] => bit ) [1] => Array ( [id] => 39549 [title] => Product Name [author] => Author Name [price] => 9.66 [type] => bob ) )

Words, bits, or what?

After a torturously long stint in grad school, I’m trying to figure out what to do next.

Spinning, exploding Excel-driven web app: How or should it be?

Sometimes, I am a front-end web developer. Frequently, I meet new people at work who want to turn really complicated Excel documents into dazzlingly interactive web applications. Besides Excel's "Save to Web App" or "Save to SharePoint" features, such people ask if I can tap into an industry to support this -- perhaps scads of agencies and web-based or downloadable tools that make "websites" or at least customizable, interactive reports from Excel spreadsheets, data, and calculations.

How to solve a complex statistics problem with a script?

In this game, you roll a number of six-sided dice to get a total. The total is either the highest single die result, or the sum of any multiples rolled, whichever is higher. For example: If I roll three dice and get a 3, 4, and 6, my total is 6. But if I roll a 4, 4, and 6, my total is 8, the sum of the two 4s.
