I am done with a first pass on my slides for Friday's presentation.
I am confident I can get buy-in to improve PNG compression.
But to REALLY compete, we need lossy PNGs. And I think that will be an uphill battle.

Oh my.
First time I've received an email from "GitHub Staff".
There is a CVE being filed against libpng.
I'm at a conference in Japan where I am giving a presentation. Not a great time to be reviewing patches...

Easiest way to get the Japan-only packaging is to fly to Japan. Obviously.

I need to take more vacations.
I got SOOO MUCH programming done while on the plane / during a rest day.
I got ~90% done (to launchable) with a compile-time state machine.

A Spooky Unix story for Halloween.
A new programmer accidentally ran “rm -rf *” as root, on one of the main computers at the University of Manchester.
He stopped halfway, but /bin, /etc, /dev, and /lib were gone.
What followed was one of the most insane live recoveries in computer history:

I finally decided to stop being lazy and do a proper analysis of my server logs after being front page of HackerNews.
But I didn't backup the logs and the default nginx rotation is only 2 weeks.

I see plenty of posts about the spending here vs. cuts elsewhere.
And also plenty of posts about how this is symbolic.
Am I the only person curious about the White House's construction?
That seems like more concrete and rebar than normal, maybe? I assume it is built to a high security standard.

Bloodlines 2 was originally announced in Feb, 2019.
I preordered the Premium Edition back then and waited 6.5 years.
I'm 2 hours in. So far, I am not feeling the negativity I see from a lot of people.
It is an story action game, not a RPG. I get people will dislike that.
More as I get further.

This whole government shutdown thing is wild.
Elected Republicans are claiming Dems want to give health care to immigrants.
Republicans, you know that sounds silly.
You know there is probably more to it...info being left out.
I urge you to think critically.

TIL about polyhedral optimization.
Neat.
I'm curious how often it can actually be used, though.

Huh. Neato.
So there is tension (pulling linearly on a thing).
And there is torsion (putting a rotational force on a thing).
There are also tensors and TORSORS. TIL.

I think a lot of programming debate (like the current OOP hate) would be resolved if languages allowed expressing compile-time & design-time better.
Some day, I'll do a talk on it and show a better language approach.

Wow.
Servers have gotten even cheaper. I thought I was getting a bargain (I am). But..I can get EXTRA bargain.
Time to start reading their acceptable usage policies.
Will they let me host game servers?

I tried but couldn't get into D&D.
I noticed Critical Role is starting their 4th campaign. So I gave it a listen.
Omg, this is so good.
Is it Thursday yet?

Man, USB is neato.
I'm already in love with differential pairs--such an elegant and simple solution to the complex problem of interference.
A separate clock line would be vulnerable to interference. Could pair two clock lines. Ooor..
USB recovers the clock from the data lines.
