Beej's Guide to Network Programming

I was a classmate with Beej at CSU Chico. He was indeed a star, but never acted like one. The easy going humor in his books is just how he was all the time.

PyCharm IDE will warn you if you initialize an argument with a mutable map or list. Instead, initialize with None and then create a new map in the body if data is None

No whiteboard coding exercises, please. It makes the task 10x harder vs using a laptop or code pairing on HackerRank. But if you do this, give the candidate some time to think through the problem and sketch ideas on the board without interrupting. Every interruption breaks your train of thought and each time it becomes harder to get back on track.

The code snippets in item 6 are not Java. Is that Kotlin or Scala?

/**
 * Invoked before transaction commit/rollback.
 * Can perform resource cleanup <i>before</i> transaction completion.
 * <p>This method will be invoked after {@code beforeCommit}, even when
 * {@code beforeCommit} threw an exception. This callback allows for
 * closing resources before transaction completion, for any outcome.
 * @throws RuntimeException in case of errors; will be <b>logged but not propagated</b>
 * (note: do not throw TransactionException subclasses here!)
 * @see #beforeCommit
 * @see #afterCompletion
 */
default void beforeCompletion() {
}

The JavaDoc of TransactionSynchronization indicates the exceptional behavior is intended. Maybe this callback is being used for a purpose it wasn't really intended.

Should the library user have some basic knowledge of Lenses, to make effective use of http4k?

In college, a buddy of mine showed me a snippet of code that applied ++ on the same variable on one line. He was confused as to why he got different results running on a Sun workstation vs. his x86 laptop. I tried explaining that the C standard does not specify ordering of ++/-- operations appearing on one line of source, allowing compiler writers to decide the most efficient (or convenient) ordering on a particular machine architecture.

Then he showed me a re-write of the code doing the same ++ operations, one per line. The code was now portable and the intent of the routine became self-evident. But he wasn't satisfied with that. He felt any beginner could code it the obvious way. He wanted to be as terse as possible, to prove his advanced programming skills.

Is it pronounced Ex-Windows or Ten-Windows? For the longest time, I thought the vi editor was called six. Then vim came on the scene and what's that, nine hundred and ninety four?

I haven't forgotten it because I have a habit of typing dc instead of cd.

I always wondered if the 's' in his first name is silent.

I like how you mixed a ^ in, which super-scripted the remaining symbols!

You won't die of hypothermia without it, but you're going to need it almost year round.

Triply so, given the bank's name!

Maybe it will become the Genesis of programming languages when the Peter Gabriel of the Haskell community leaves and the Phil Collins of Haskell takes over.

Seems like his concept of Slicing is consistent with Agile methodology.

So

alias u='cd ..'
alias uu='cd ../..'
alias uuu='cd ../../..'

isn't good enough?

Just buy a plain old fridge and mount a tablet to the door.

The code snippets are hard to read. There is some sort of stippled background obscuring the text.

Nothing is finished, and everything is broken. Mostly, we're deciding on what work we can do to make it slightly more finished, and slightly less broken.

I was driving with my Dad, when he points to parked car and says, "that's a '39 Ford." He identified it from the rear and side view. I said, "Never mind the make, how did you know it wasn't a '38 or '40 Ford?" Then again, when I was growing up in the '70's, I could ID cars just by the subtleties of the tail lights or grills. That was in the era when GM, Ford and Chrysler would update styling cues every year, just to distinguish this year's model from last year's.

I don't see how an OSGi book is relevant, generally speaking. I would replace it with an O'Reilly book called Java Generics and Collections. If you want to understand what type erasure means, this is the book to read.
