Part 1

In the day 2 challenge, we’re playing Rock Papers Scissors.

We’re given a strategy guide like so:

A Y B X C Z

Left column is “their move”: A means Rock, B means Paper, C means Scissors. Right column is “our move”: X means Rock, Y means Paper, Z means Scissors.

Each line corresponds to a turn, and we must calculate the total score we get. Picking “Rock” gives 1 point, “Paper” gives 2 points, and “Scissors” gives 3. Losing the round gives 0 points, drawing gives 3, winning it gives 6.

What’s a ktls

I started work on ktls and ktls-sys, a pair of crates exposing Kernel TLS offload to Rust, about two years ago.

kTLS lets the kernel (and, in turn, any network interface that supports it) take care of encryption, framing, etc., for the entire duration of a TLS connection… as soon as you have a TLS connection.

For the handshake itself (hellos, change cipher, encrypted extensions, certificate verification, etc.), you still have to use a userland TLS implementation.

Just 8 days after the last release, rock 0.9.6 is out.

To update, run git pull && make rescue as usual. To install from scratch, clone the repo, cd into it, and run make rescue from there - it’ll download the latest bootstrap, compile itself from C, then recompile itself from ooc.

Running rock -V should give you something like this:

It feels like an eternity since I’ve started using Rust, and yet I remember vividly what it felt like to bang my head against the borrow checker for the first few times.

I’m definitely not alone in that, and there’s been quite a few articles on the subject! But I want to take some time to present the borrow checker from the perspective of its benefits, rather than as an opponent to fend with.

Damian Sommer did a casual AMA on Reddit recently, about his upcoming game, The Yawhg. I got to ask him a few questions. Here’s what he had to say.

What brought you out of your usual “let’s make fucked up platformers” style?

“I was just kind of tired of them. There’s still one more platformer I really want to finish, (The Clown Who Wanted Everything), but besides that, I’m just extremely bored of them now.”

Intro

When I started my Patreon, I had no idea if it would work at all. The whole thing seemed like a gamble: spend an inordinate amount of time writing quality articles, and hope that folks will like it enough to kick in 5, 10, or 50 bucks a month just to see more of them.

I’m happy to say the gamble paid off - literally. Take that, impostor syndrome!

Hey all, thanks for checking in!

After much soul searching, I have arrived to the following conclusion:

• Teaching folks about stuff is my jam.

I’ve been writing multiple articles that sort of read like course material, if there was no dress code, maybe?

In 2013, I organized a 1st year Computer Science student project. Instead of making them implement “control tower software” for a fictional airline, I decided to go for something real - the BitTorrent protocol.

rock 0.9.5 is out! It’s the meanest, slimmest, baddest rock release yet.

To update, run git pull && make rescue as usual. To install from scratch, clone the repo, cd into it, and run make rescue from there - it’ll download the latest bootstrap, compile itself from C, then recompile itself from ooc.

Running rock -V should print this happy little version line:

Good morning! It is still 2020, and the world is literally on fire, so I guess we could all use a distraction.

This article continues the tradition of me getting shamelessly nerd-sniped - once by Pascal about small strings, then again by a twitch viewer about Rust enum sizes.

This time, Ana was handing out free nerdsnipes, so I got in line, and mine was:
