The title says "(1996)", but the document itself says "This is a rendition, after scanning, OCR, and editing, of an internal Bell Labs Technical Memorandum dated January 7, 1972."

If you want to make an argument about instructors giving students incorrect information, make that argument. I might even agree with you. If you insist on conflating it with sexual abuse of children, you are an idiot.

Nobody has mentioned that scanf has undefined behavior on numeric overflow. If INT_MAX is 2147483647 and the user enters 2147483648, the behavior is undefined. (That doesn't just mean you can get an arbitrary value for a and/or b.

I've mentioned elsewhere that strncpy is not a "safer" strcpy. Even if it were, there's safety and there's safety. A function (like strncat, for example) that quietly truncates your data if it's too long isn&#x

NULL is (a macro that expands to) a null pointer constant. The null character '\0' is commonly called NUL. I've written about strncpy: http://the-flat-trantor-society.blogspot.com/2012/03/no-strn...

Does the President's authority as Commander in Chief extend to creating a new branch of the armed forces? The US Air Force was created by an act of Congress (the National Security Act of 1947), not by a Presidential order.

C really does stress the difference. Look up the definitions of "pointer" and "array" in the C standard. They're entirely distinct concepts. p[i] is equivalent to (p+i), and that's possible because both the in

"always use strncpy" I disagree; you should almost never use strncpy. Its name implies that it's a "safer" version of strcpy, but that's not what it is at all. If the target array isn't big enough, it ca

I wouldn't call "arrays are pointers" a polite fiction. I'd call it a dangerous misconception that makes it more difficult to understand what's really going on. The language is partly at fault for a couple of rules

"In C an array is generally just a pointer to the first element." No, arrays are not pointers. "A String is generally a pointer to a series of bytes (chars) which ends in a byte value of 0 to indicate the end of the string.&q

Speaking as someone who happens to have a full beard, I find your use of the slur "neckbeard" insulting. Find another way to say whatever you meant.

We had a Tera MTA (serial #2, IIRC) at SDSC when I worked there. It looked really cool, but I never got to use it. Tera bought Cray Research in 2000 and renamed itself to Cray, Inc.

As I mentioned in my comment on the article, setting $TMOUT if you want a timeout on a 'read' command is unnecessary and unclear. Just use "read -t": read -t 5 foo || foo='No reply' Setting $TMOUT affe

It took me way too long to figure out that the article isn't about literal whale watching. I was expecting something about a small number of customers spending large amounts of money to go on whale-watching cruises.

Yes, it is, but I also initially assumed that this was a successor to SQLite3. No, it didn't take long to correct that misunderstanding, but it would be nice if the title were clearer.

One simple requirement is that a README file should include, near the top, a brief summary of what the project is. I've seen too many README files that leave that out. Knowing what changed in the latest point release doesn't help
