I at first planned to get an Antminer S9 bitcoin mining rig but it requires a power supply plugged into 220 volts. The only 220 outlet in my apartment is for the stove.

I came up with what I regard as a practical and safe way to plug the supply into my stove outlet, but then I had a look at the Antminer L3+ LiteCoin mining rig with the APW3++ supply.

The L3+ only requires 800 watts, well within the amount of juice that the APW3++ can provide when plugged into 110 volts.

Here in the Pacific Northwest electricity is only 8.16 per kilowatt-hour.

I consulted both a bitcoin mining profit calculator and a lite coin one. The L3+ lite coin rig was calculated to earn roughly the same profit as an S9 bitcoin rig, a little over $7,000 per year at the current exchange rate.

In other news I followed the advice of a friend to invest in the NAGA Initial Coin Offering. I bought 1,400 NAGA tokens. This particular friend has always given me good advice.

I was buying and selling bitcoin, lite coin and etherium at coinable but was no more successful than if I bought some then held onto it - "hodling" as the 1337 crypto-investors like to post.

My next paycheck was looking quite remote because my driver was totally borked on macOS 10.13 High Sierra. We were surprised because it works really well on 10.12 Sierra and earlier systems.

However one of my client's coders came up with a different approach that involved a userspace LaunchDaemon talking to the driver via an IOUserClient.

He got it mostly working but there was a serious problem - still a showstopper.

Today I fixed the showstopper.

His workaround unfortunately uses too much CPU. Possibly I can fix that by using an x86_64 assembly instruction that disables one line of the memory cache with the expectation that the code is going to write into the entire line.

I could use intrinsics but I once read an article that made a good case for using assembly instead: sometimes intrinsics yield very poor code generation.

When I get that next check I'm going to devote $6,500 to fund my 2017 Individual Retirement Account at eTrade, then use it all to buy an S&P 500 index fund. I'm not going to blow it all on cryptos, just some of it.

And I'll be donating $1,000 to the Right 2 Dream Too homeless shelter, as well as sending my Mom another $1,000. She was paying for my storage while I was homeless.

I'm going to get most of that stuff out of storage when I receive my renewed passport six weeks from now. This because that "most" is in Canada. To have it shipped into the US the truck driver must have a photocopy of my passport.

R2D2 is operated by homeless people. It's particularly forward-thinking in that one can sleep during the day there. Whenever I lost the bed lottery at the Portland Rescue Mission I stayed up all night then slept at R2D2 the following day.
