How many chapters of a textbook can you go through? And please list concrete examples and the name of the textbook (even if you only did it once). I'm just curious.
I can do 1 chapter of a college textbook per day (without doing exercises).
But it's difficult for my attention span. I've...
So I want to look for specific characters within my .html and .txt files offline. But even when I google offline search engine, I can't find a suitable search engine. Windows Vista Search doesn't seem to have a search engine that works for strings within particular files (it just seems to work...
The problem with such links, though, is that they often link to very small files.
For example, MIT OCW files.

Links to say...
Apparently, not in the Temp folder.
So then, where could I find their locations? Certainly,somewhere on the hard drive because you can instantly switch to an "already-loaded" segment of the video.
So yes, you may ask - why would I need to, since Gmail offers so much space? Well, my reason is that I often like to download everything from Gmail onto disk, and this is where I'd like to delete attachments.
As we know from movies such as "Star Wars" and "Star Trek", the characters move as if they were on a planet. The question is - could there be a mimic to gravity on the spaceship? Obviously, we cannot put too much mass on a spaceship, which would make the spaceship much more inert to...
Thanks for the replies everyone!
If old data can still be retrieved when overwritten (through whatever processes it takes), then is disk-writing an irreversible process? Which means that the more you write/delete off the disk, the more stressed out the hard disk will become? And do different...
So say, I'm writing a program with an infinite loop, and that I'm trying to write a file that is as large as the disk drive is, in the smallest possible time.
What would be the best algorithm to do it?
Clearly, such an algorithm would consume as many system resources as it possibly could. So...
Then you e-mail them to the professor, or visit prof during office hours.
Because some professors are evil and want everyone to attend class, so then they cover some topics ONLY in class, without even posting them on the course website.
And because it costs $$$.
Oh, sorry, title post was wrong, actually, identity matrix cannot be a product of 3 or 5 row exchanges - but did not say odd number of row exchanges.
hm. After 1 swap, we have 2 rows diferent. After 2 swaps, both rows can swap back to identity, one dif row can swap with one same row, or two...
Problem: #29 in Strang Linear Algebra
Prove that the identity matrix cannot be the product of 3 row exchanges (or five). It can be the product of 2 exchanges (or 4).
Now, to start, we try to count the number of rows that are different from the identity matrix. For the first row exchange, it's...
Question. Can someone please interpret what exactly this person is saying?
"Its effect is to permit the brain to seamlessly conduct multiple actions by coordinating thought patterns sequentially in the prefrontal cortex. Under the influence of L-DOPA, a dopamine analogue, Dr Sacks’ patients...
