There was virtually no CPM software adapted to the C=128

I wasn't aware that it needed to be adapted. When I think of CP/M software I don't think of fancy programs highly customized for specific hardware -- if it had a keyboard and at least an 80x24 screen, it was happy! Being able to run CP/M software was one of the main reasons I got a C128, and I did so for several years with no more adaptation than setting up book scripts on the floppy to automatically load everything the way I wanted.

Comment: Don't forget self-employment tax! (Score 1) 128

For many, self-employment tax is another really good reason to try to steady things and avoid "bouncing revenue", if there's the chance that you could end up taking a loss the next year. Big profit one year? Pay big tax! Loss next year? Sorry, bud, no refund!

I confess to getting first-hand experience with this, as I'm accounting on an accrual basis, and just paid taxes for a rather large amount of work done that may eventually have to be written off as bad debt, or at the least is going to cost me to collect, since the guys behind the business have disappeared, and I'll likely go into the red next year. Paying >15% tax on money I haven't actually got...ouch!

I wouldn't have thought of "dialup" to describe a high-latency connection. (Gee, by eliminating your local router, it drops a hop, and should be faster, right?)

Years ago, the latency from my DSL provider to some locations was so bad (>500ms ping times) that I actually dialed another ISP on when I was using an especially "chatty" protocol, and enjoyed better overall performance, even though the max theoretical throughput was only 1/20th what the DSL connection offered..

When I lived in an urban apt., I had fun making scary audio recordings, etc., but I live out so far now that in 13 years we've never had a single trick-or-treater visit us! So, if anyone visits us on Halloween, it'll probably be someone we know and, and they'll just be invited in for a visit, etc.

> there is no such thing as a "negative" tax bill.

Wrong. in the U.S. *most* federal tax credits are non-refundable, but not all. If you don't make a lot of money, but qualify for refundable credits, it's quite possible to have a negative FIT bill.
I need nothing deducted from my paychecks, because my FIT bill is negative every year. Now if you add in all of the other federal, state, and local taxes I pay, I still pay more than I get, but those are separate "bills".

I have no idea, and anyone "on the grid" who claims to know is fooling themselves.

Perhaps. I'm a member of a smallish PUD, and though I'm not involved in the power purchase, we're regularly apprised of where our power is coming from and going to, and have statistics answering exactly that question. We don't have exact accuracy, but we can get a pretty good idea %-wise at any given time.

The degree of technical confidence is inversely proportional to the level of management.
