Will Rogers on “Trickle Down”

A few weeks ago I was scrolling through my Facebook feed when I saw one of my liberal friends had posted humorist Will Rogers’s famous “trickle down” quote. My friend didn’t offer much (if any) commentary on it other than to post it, and indeed I’ve seen it widely shared. It’s worthy of sharing.

Then I noticed a few comments down that the quote had drawn a dissenting voice. A conservative friend of his took offense at the quote, essentially griping that if people would simply work hard they’d get whatever manna that was coming to them. Conservative Guy then berated Liberal Guy for doing nothing for the country and implied that Liberal Guy wasn’t a true citizen because Conservative Guy served in the military and Liberal Guy did not. It didn’t seem to matter to Conservative Guy that Liberal Guy had worked since he was 16 in a very physically-demanding line of work.

I now remember why I left DOS behind

This is harder to emulate than you think.

Because I apparently haven’t had enough technical challenges to solve, this weekend I decided to return to my little side project of getting my old DOS-based PCBoard BBS running in a virtual machine. For this project I’m using oVirt as the VM host and booting FreeDOS 1.2.

Needless to say, I’m running into some challenges. My first thought is: oh my God what a kludgy mess DOS is! It’s a half-assed solution on top of a half-assed solution on top of a half-assed solution. Device drivers up the wazoo. More than 640K memory? Gotta load EMM drivers. Want to use a CD? Load an ATAPI driver. Want USB? Hah, not available! Want networking? Find a packet driver for your specific network card and ensure you use the right interrupts. Oh, and you’ll still need to load a separate TCP/IP stack! With so many parts to the puzzle it’s a miracle anything ever worked at all!

It took me a little while but I finally did get my DOS VM networked via TCP/IP. Then when I loaded PCBoard it initially seemed to be looking for a (non-existent) modem. Subsequent runs had it complaining about “Cannot run as a child of BASIC” before exiting. I am assuming this is a problem with the way PCBoard was compiled using QuickBASIC and QuickBASIC (QB) might not be playing nicely with FreeDOS. I’ve seen others say QB works fine with FreeDOS but I don’t know if that applies to the compiled programs or not.

So, now I’m on to installing a DOS VM using MS-DOS 6.22. I can’t imagine QuickBASIC not liking MS-DOS.

The project continues. It may or may not be worth the trouble but at the very least it is a reminder of just how far we’ve come with operating systems!

Sound bite: Despite Pono’s promise, experts pan HD audio – CNET

This isn’t a new story but it’s one that I found very enlightening on the topic of digital audio formats.

Pono Music’s roaring success on Kickstarter, raising $4.3 million so far, shows that thousands of people believe better audio quality is worth paying for.

The company — backed by star musician Neil Young and selling a $400 digital audio player along with accompanying music — promises people will hear a difference between Pono Music and ordinary music that’s “surprising and dramatic.” The company’s promise is based in part on music files that can contain more data than not only conventional MP3 files, but also compact discs.

There’s no doubt that highly compressed music files, played over tinny laptop speakers or cheap earbuds, leave a lot of room for improvement. But outdoing CD quality? That’s a harder sell.
