On the last day of AsiaBSDCon, George Neville-Neil gave the keynote talk, Security Fantasies and Realities. Some of it was good and some of it was bad. One of the central points is that the ioshitsunami is coming and in order to save humanity we need to do more of the good security and less of the bad security. One of the, or perhaps just the, good security things to do is hardware root of trust, which I will call TPM, although it has a few brand names.

Some people tweet. (Me, previously.) Some people toot. (No, thank you.) I have decided to honk.

I got a new Thinkpad, the 6th gen (2018) X1 Carbon, herein referred to as the t6x1c because why not. I’m not the first to get this laptop, and I’m sure some complete reviews are out there, but a few more personal notes I found interesting.

I’ve been a rather happy lua user for a few years. In particular, the luajit implementation. But as part of an ongoing overhaul of this and that, I decided to rewrite all my lua code in go. Or wait, let me rephrase that.

I wanted to make an interactive terminal interface for something. Usually I just bang out some vt100 escapes to move the cursor around, color this, erase that. It’s crude but effective as long as the number of screen elements is kept to a minimum. This time, though, I decided on a slightly more disciplined approach, and so I was looking for a library that might assist in drawing views of various sizes, and input fields, and buttons. The works. In go.

I’ve been paying a bit more attention than usual to web interfaces, and there’s a few examples which really get to me. GitHub is one that’s annoyed me for a while, but I didn’t quite know what was wrong until I looked at some screenshots to see what was frustrating me.

I needed a (text) diff algorithm, and if you search for one you mostly come up with the Myers algorithm. But then I stumbled across something called patience diffing, and it turns out to be just what I wanted. It’s already described elsewhere, but it seems more people could stand to know about it, so here we are. It’s easy to understand, and more importantly, usually makes pretty diffs (often prettier than Myers).

But what about screen readers, you ask. Somebody did a web thing you don’t like. Doesn’t this break screen readers?
It seems the easy way to find out would be to test. But that requires caring about screen reader usability enough to actually have one on hand to test. Much easier to wag fingers. Screen readers are the starving children of web accessibility arguments. Why don’t you care about the starving children?
It’s borrowing somebody else’s concerns to score internet points. Oh, hi, I just wanted to try this on and post a few comments, you can have it back now. Thanks. I wouldn’t want to have to think about this all the time.
I mostly like go, but after working with it a bit more I realize there are a few jibs of which the cut I do not like.

I had some go code I wanted to quickly iterate on. Go compiles pretty quickly, but not instantly. Like 2 seconds. In some places, I can use gopher-lua, which gets me pretty close to 0 second iteration delay, but there’s a big up front development cost. It’s useful for scripting an existing program and adding custom behavior, but less useful for experimenting to see what happens when I do X. What I need is an actual interpreter for go, not an interpreter in go.
