Algebra

My mind was completely blank during today’s mathematics test. I stoned for 1/3 of the time, just staring at one of the questions. For some reason I just couldn’t solve the equation, which involves cube-rooting 121. After wasting 10 minutes and finally giving up, I didn’t even have the time to check or attempt the bonus question. Later after the test I found out that I had made a simple subtraction mistake in the previous step and the number I’m supposed to be cube-root was 125…

I think that was my WORST performance in a maths test/exam EVER. I don’t even think I have get above 75%… Sigh, it was reeeeeeeeaaally easy, but somehow I JUST didn’t see all my obvious mistakes. Maybe it’s because I didn’t sleep well last night. Sigh…

I’m pretty sure I’ll do horribly for Friday’s Chinese test too… Well there’s always next week’s Japanese test to look forward to.

And for news: Microsoft could lead to doom. Wired news.

CAMBRIDGE, Mass. — Dan Geer lost his job, but gained his audience. The very idea that got the computer security expert fired has sparked serious debate in information technology. The idea, borrowed from biology, is that Microsoft has nurtured a software “monoculture” that threatens global computer security.

Geer and others believe Microsoft’s software is so dangerously pervasive that a virus capable of exploiting even a single flaw in its operating systems could wreak havoc.

So, what’s new?

IO2Technology.com. Remember that mid-air display technology I posted some months ago?… Looks pretty promising. The images are slightly distorted due to the nature of vapours, but it certainly looks better than those projectors in Star Wars episode 4.
