I'm back from a long vacation. I wanted to see Tron: Ares.
It isn't in any theater near me.
It isn't on Disney+ (which has horrible stream quality, btw...is this 720p?).
It isn't for sale on bluray.
Disney, I'm trying.
Work with me, here.

You ever just pause and recall how INSANE it is that we have satellites in space to monitor weather?

Today I learned RDMA (Remote DMA) is a thing that exists.
This is wild to me. Apparently, it can be secure. But I'm skeptical.
Anyway, with it you can write to another comp's memory without either CPU being involved.

Possible race condition · Issue #29 · ProgramMax/FileReadSpeedTest
There seems to be a race condition when thread_count != queue_depth. The timing values are printed as 0. It is possible that context[i]->time is set on the wrong i.

Someone make a motherboard with two temperature sensors already so I can do coolant vs ambient.
Actually, heck...maybe I'll just make my own USB device to do it.
"Be the change you want to see", right?
But the BIOS still won't recognize it.
I guess it needs to control fans + pumps then.

I just gave my PNG presentation and I think it was well received.
The part I thought would get a lot of push back (new lossy PNG format!!) actually got support and contributing ideas.
Crazy stuff coming around the bend for PNG.

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...

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:

Eff.
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.
