I find that oldstyle (or text) figures are much easier to read in any context outside of simple assignment. Are there any low-ambiguity fonts, monospaced or proportional, that have text figures and other programming-friendly features, such as marked zeroes; aligned braces, operations, and other symbols; and bold and it... |
I've been trying to read through the RoR API to try to learn things that the tutorial missed, and I haven't been able to follow it at all.

Azure ACS offers OAuth and OpenID providers, and now that ASP.NET 4.5 offers the same thing, without the added cost, is there any reason for a .NET developer to consider ACS?

Programming languages and programs (as wells as individual functions, objects, etc.) are often described as being "safe" in one way or another. For example, they could be "type safe", "memory safe", "exception safe", "thread safe" - even "reentrant". Each of these concepts is about preventing erroneous or damaging code... |
I am going to be a third year computer science student and I have read Head first Java, Head First C, and I am currently reading C++ which is the language that I like the most since it has a good teaching style for people with experience.

A study shows that lines_written/time is language-independent and application-independent for most programmers. If this were true it would imply that the most terse a language is, the more productive a programmer can be on it.
Where can this study be found?

I was wondering if there was a valid use case for being able to properly define the specific internal properties and functions of a class in a way similar to how an interface defines the public properties and functions of a class.

I've been thinking about that for quite a while actually. I am not a native English speaker myself but still, I have years of programming experience and I always asked myself this. Why is it named as Exception but not Error since they are errors?

In programming we're often faced with a choice: cover each conceivable use case individually, or solve the general problem:

The IO monad in Haskell is often explained as a state monad where the state is the world. So a value of type IO a monad is viewed as something like worldState -> (a, worldState).

I work better when I have some firm foundations. This helps me to solve everyday problems better, because I can generalize them. The thing I find in programming is so many things are black boxes.
