But if you do that you had better take into account the increased earning potential thereafter...
(That said, when an advisor says that double majoring is going to cost you money in the long run, they probably aren't mistaken).

Only if the double major takes more time. My boyfriend's doing a double-degree in 5 years, so yeah, he might end up hurting from that, since he never intends to use one of his (impractical liberal arts) degrees, but I'm doing a double major in four years, so why would it cost me?

@Chai

If one of your majors is expected to bring you zero dollars, the time spent studying for it could be spent working at a part time job (opportunity cost).

Of course, I'm not criticizing your choice as some things are worth more than money.

I think that misunderstands the way double majoring works. Let me take a simplified model of the system:
Say your degree is divided up into thirds, with one-third general education credits, one-third major credits, and one-third elective credits. Assume your individual semester is broken up approximately similarly. A double major simply takes the one-third elective credits and exchanges it for a major, which also costs 1/3 (note, this will vary from school to school, but is my experience at a research university). On a semester basis, this means that your schedule would be the difference between taking GE, major, and elective classes, and GE, Major 1, and Major 2 classes. Furthermore, it's rare for people to take or not take a job based on the classes they're taking, especially since most students who get part-time jobs do so on federal work-study (us unlucky ones who have no work-study have a hell of a time finding a job at many schools). Lastly, it's pretty hard to calculate whether an additional major would bring you literally $0 or have some added benefit in hiring or salary. My majors are music and philosophy and I'm not pursuing the music. On the surface, music would seem to have a $0 benefit. The calculus changes, however, if my philosophy research is in aesthetics, and the admissions committee looks at my music as a bonus that will give me more practical knowledge, much like a science major might help someone in philosophy of science. Likewise, someone with a double major in art history and French might get a gallery job that gives her $0 additional benefit, but might later send her to a sister gallery in Belgium on the strength of her French skills. Basically, you never know when the other major will come in handy.

There are usually somewhat more classes in a double-major, I think; but it's true that the name is misleading, as it's not really "double." You don't have to take as many classes in either major as you would if you had just one, and there's often a lot of the same classes in both majors, which obviously you only have to take once.

Also, everything (else) is worth more than money. Not just some things.

Err, I think the Commodore 64 was the keyboard. In those days (and I'm talking ancient history, i.e. my generation) computers were all one unit (BBC Micro, Atari, Vic 20, Sinclair Spectrum, etc.). Take a look at http://en.wikipedia.org/wiki/Commodore_64. May be worth something on ebay if you don't want to keep it. All you need is a power supply with whatever bizarre plug they put on it.

No, cost and net loss are different things.
Counting opportunity cost essentially comes down to counting what you could have done instead with the resources that you used other than just money (usually, time). Often things have a really high cost - but also have a net gain, such as education. Sometimes the only significant cost is the opportunity cost, such as taking a month out to renovate your house - the cost of not working for that month far exceeds what you might spend on paint and wood but even then you may consider that to have a net gain if it pushes up the value of your house enough or if you consider the satisfaction of a job well done plus the added value to your house to exceed a months salary (yes, costs can also be really subjective).

In addition to that, the cost to you of that month's labour at either work or your house could be different. And so you would be saving yourself effort.

Well you're freakin' lucky. At my school, in order to double major you HAVE to take 5 years worth of credits. And you only get one minor for each major you already have.

Today I learned that a guy I went to high school with died yesterday. Electrocuted on the job. He was married and had at least one child; and he was my age, so around 28. I didn't know him that well (I didn't socialize much with anyone in high school), but what an incredible tragedy. I can't imagine what his family must be going through.

Today I Learned that Blender's Python API is packed with lies and has a smooth, buttery coating of "returning the wrong data".

If you ask for a global location, you get a global location. That's okay
I need a location relative to an object's parent. This is called "localspace".
I ask for a local location. I get a global location.

Luckily:
If you ask for a local matrix, you get a local matrix.

So that all worked out nicely, and solved an age-old communication issue between Blender and my program.

It's also not a wise idea to relieve the stress immediately after by swigging whisky from a hip flask and lighting a cigar whilst still dressed as the fat guy. You can ruin the image for passing kids. Hey, I've become bad Santa!

Today I learned that many PS2 homebrew/hack-related programs do not support component video output and must be displayed on an analog TV using the A/V cables. I also learned that the "text editor" in uLaunchElf is no good for editing IPCONFIG.DAT because it sticks some NULL bytes at the end of the file, triggering an error along the lines of "IPCONFIG.DAT format is [...]".

For the sake of Googlers (oddly, I did not find this tidbit anywhere on Google), this involves/affects the Playstation 2 program hdld_svr.elf (the server for hdl_dumb and hdl_dump) as well as those mentioned above; you'll just see a black screen.

(Why is it that every time I try to use my PS2 I have to spend several hours doing some completely different hack than last time? Why do these programs that boast over 95% compatibility never work with the few games I have? Why could Sony not have manufactured the damn things properly so I could just use the original discs in the first place? :x )

Yesterday I learned that TV is still as annoying as it was last time I watched it, but Discovery Channel has some decent stuff in between the blaring ads, and apparently India's laws regarding driver's licenses are either very lax or not well enforced. That being my conclusion after someone on Canada's Worst Driver said they learned in India by (his words) "hit and miss", just getting into a car and doing what seemed right (which included such nonsense as driving between lanes for more space, not even knowing what the signal lights are, etc), before ever getting a license. Now that show is pretty damn scary... but I'd like to try those courses myself, maybe improve my own lousy driving skills a bit. :P
