VGA programming

Ah, the good old days of using INT 10h, AH=0x00 graphics modes to write directly to video memory at 0xA0000/0xB0000/0xB8000 (depending on the mode).

Nir Lichtman walks us through some of the things I was teaching myself in middle school – writing VGA graphics in assembly (often using the great book Programmer’s Guide to the EGA and VGA Cards by Ferraro, Richard F.

I even wrote my own (terrible) little paint program that would then save the buffer into a file and reload it. What good times!

Jon Krakauer Talk

Jon Krakauer Talk

Jon Krakauer is probably most famous for his book Into Thin Air that covered his first-hand experience of the 1996 Everest Disaster, but he also wrote tons for Outside magazine.

What’s interesting about this talk is his description of the climbing and outdoor world of the late 80’s and early 90’s. It is interesting how much of a different world it was back then. This kind of 90’s era spirit of adventure is what got me into Mazamas and climbing in the Pacific Northwest in the early 2000’s. I remember it well. It was a very idealistic time in which people talked about the purity of pushing yourself in climbing. Portland saw famous climbers come through town semi-regularly as they practice on the peaks in the Pacific Northwest and to do talks – as mini-celebrities.

Climbing of that era was almost a religion that saw young, incredibly talented and athletic people from everyday backgrounds flying around the world to the most remote locations when the world was much less accessible as it is today. It’s a great little time capsule of an era that’s long gone.

Airpod/iPod cleaning that actually works

Airpod/iPod cleaning that actually works

I bet like a lot of folks, you have a set or two of airpods. I have an older set I use for running since the sound in them after a year or so was starting to get quieter and duller. Then, it got to the point I could barely even hear out of the right one.

Before I tossed them, I decided to see if cleaning them out would help. There wasn’t any obvious ear wax in them. So I looked online and sure enough Apple itself now has a video and procedure on how to do this.

I tried the method out. The first go seemed to improve things, but I wasn’t sure. The next day I tried it again, and the right airpod suddenly had a lot more volume. I tried it a 3rd time on the 3rd day, and low and behold – they were practically like new (well – except the battery life was still only good enough for a 60 minute run – but that’s another story).

I had tried this method before, but using isopropanol alcohol. It largely gave poor results. It seems the key is to use micellar water – usually for removing makeup and dirt on sensitive skin. I use Bioderma – Sensibio – H2O Micellar Water and it seems to be what they use in the video (it has a distinctive translucent red cap).
