the stove over to induction next. I hate it when the batteries fill back up by 10am and I waste solar meanwhile I am still buying propane for the appliances.

It's possible. For the 11 months I've been cooking from excess solar power (December is a little short). I still carry propane for heating and a few things that seem to work better over flame.

In the past I've aliased rm to a wrapper that showed PWD and the files to be affected, slept a couple seconds in case I wanted to abort, then shredded smaller files, rm'ed big files, or placed in a Trash dir for certain kinds of files (.conf, .cfg, etc).

I might try to find or rewrite it.

PDAnet I've tethered a laptop to a phone via usb and bluetooth that way. Nowadays I just run my SIM in an LTE router and share the connection via wifi.

hide tether usage if possible

Some solutions involving tweaking TTL.

I have made countless mistakes since the 90s, mostly involving rm. The most recent one was yesterday when I was trying to rm files in a directory with lots of other unrelated files.

I don't remember the exact failure, but I was shooting for something like rm *lng and typo'ed rm *;ng (those chars are next to each other on the kb). This happily rm'ed * (d'oh!) then errored on the nonexistance ng. :-(

Agreed. I haven't read the article yet, but my first thought was "how am I going to turn that off"

During periods of short supply and/or increased coffee has been often been replaced or augmented by various other ingredients. For example:

... during the American Civil War, Louisianans looked to adding chicory root to their coffee when Union naval blockades cut off the port of New Orleans. With shipments coming to a halt, desperate New Orleanians looking for their coffee fix began mixing things with coffee to stretch out the supply. Acorns or beets (cafe de betterave) also did the trick. Though chicory alone is devoid of the alkaloid that gives you a caffeine buzz, the grounds taste similar and can be sold at a lower rate. -- source

What are everyone’s thoughts on bots like piped bot and tdlr bot

I don't mind them. If I did I'd block them.

Closest I've come to Mad Scientist was probably yeast ranching to control costs in homebrewing.

  • sterilize agar media and plates/tubes in poor man's autoclave (pressure coooker) and hood (open oven door and vent fan) - infection rates were surprisingly low with this low-tech approach. I lost maybe 5% of cultures to spurious growth.
  • streak yeast from $$$ pure liquid cultures, grow, store if successful.
  • also experimented with yeast suspensions in sterile distilled water based on a 1930s science journal article from a dude in Africa. The suspensions did better in the heat where agar would just remelt....
  • a few days before needed scrape the streak into a small amount of sterile wort (20ml? on a homemade stirplate (PC fan and HD magnets under an unpended tupperware bowl!), stepping up to pitchable volume coinciding with the batch cooling to pitch temperature....

It was a lot of fun and instead of one 5gal batch of beer from an exotic $20 yeast sample you could get as many as you wanted. In practice I usually did 5-10 cultures from each pure sample. Could do more than that but there was a limit to how much stuff I could sterilize in my "autoclave" at one time.


Edited to add: I successfully cultured yeast from hefeweizen, but since what's in the bottle is typically for secondary/priming rather than primary it was only for fun. I had 100% failure trying to harvest wild yeast from the air or sampled from fruit skins. I couldn't isolate the yeast from other critters.

I have driven and found joy in many cars: Pinto, beetle, 2CV, original 500s, 1940s Ford tractors, beater pickups including a 1949 International, HMMWV, etc. Mopeds (like 1970s Puch), ratty motorcycles. They all make me giggly.

I had to think a few minutes about one that was just terrible, no redeeming points I could find: first (north american) gen Hyunda Excel What a soul-sucking turd.

 

I recently bought some closeout honeycrisp apples and bosch pears and ate most of them. I had one of each left over and decided to skin each and cook them down with a bit of cinnamon and lime juice. Then I decided I'd make pancakes the next morning to make use of it.

I cooked down the fruit on the 300w lab hotplate. Tried to use it for the pancakes in the naan pan but the 4" head was too hot in center. Tried to use a flame diffiuser but 300w wasn't enough grunt to get through that. So I ended up cooking the pancakes over a single-burner propane stove.

They tasted better than they looked. :-)

 

I found a tennis ball in a park in SF, and figured it’d make a good aromatic medium for the peppermint oil I bought to repel mousemonsters. I cut it into quarters with a utility knife.

I applied peppermint oil to each fuzzy surface and mounted one under the hood and one on the floorboard near where I saw mice enter.

 

I've noted before that when I stealth camp in cities my charging percentage from alternator increases from ~5% to ~10% of total production. The increase isn't needed (solar could cover it) but the alt gets a chance to play.

Since I am moving at least twice a day (3x with PF showers) I've had an opportunity to record a higher frequency of engine starts and LFP bank acceptance. The setup:

  • 180A alternator that typically runs at 14.2v
  • Battery Doctor VSR setup left over from my previous FLA bank
  • 150Ah 12v LFP bank
  • SoC and voltage measurements below taken from BMS before engine start
  • current measurements taken from BMS though it agrees with shunted battery monitor. (I can see the BMS via bluetooth from the driver's seat but I can't see the monitor)
  • solar contribution and loads ranged widely, leading to variance.

Over the last ~20 runs, the average state of charge was 72%, bank voltage 13.20v, charge acceptance 0.183C (27.39A)

    SoC Vbatt       C       A
    60	13.07	0.245	36.75
    72	13.15	0.130	19.50
    69	13.13	0.120	18.00
    27	12.95	0.270	40.50
    80	13.29	0.150	22.50
    80	13.27	0.240	36.00
    81	13.30	0.170	25.50
    77	13.22	0.165	24.75
    39	13.03	0.260	39.00
    95	13.30	0.115	17.25
    48	13.06	0.235	35.25
    86	13.56	0.120	18.00
    90	13.25	0.220	33.00
    90	13.26	0.165	24.75
    62	13.08	0.240	36.00
    92	13.27	0.084	12.60
    92	13.27	0.090	13.50
    58	13.07	0.235	35.25
    89	13.26	0.140	21.00
    84	13.26	0.215	32.25
    49	13.07	0.225	33.75

Given average charge acceptance of 27.39A, the obvious comparison here is to a 30A DC-DC like the Orion-TR. The DC-DC would have a much more stable charge rate, typically ~30A except late in the charging process when acceptance at Vabs tapers.

 

Charge to ~100% SoC then allow the system to settle back to the quasi-float voltage... Final measurements taken when the sun had gone down enough that solar could no longer hold Vfloat.

 

my first vinagaroon IRL and I did not like it. Also a tarantula, but that was much less freaky.

 

I have a prescription from the VA coming in, and an Amazon order in the queue. I’ll try to time everything arriving in 14d so I can collect everything, get a shower at PF, etc

Heavy rain was forecast in Los Alamos for the next few days (and lighter for the next week). Highs in the 60s. I needed to move (14d) so I could either scout a location within acceptable distance or chance going into Santa Fe.

 

You know the locals are well-paid when you see a Ferarri at the grocery store.

 

Made some cheddar biscuits in a sandwich press; yummy!

Normally the dog is in the pics looking at the food but she was still busy on cleanup duty.

[Vpanel] can reveal much after we learn what the controller is doing.

 

The spot was lovely but had mice. I trapped them but they kept coming. By the time I decided to relo it was too late; they had chewed into the wiring harness...

Last night I watched Oppenheier. I took Muffin out for a break afterwards and could see the lights from Los Alamos, the town Oppie built for Project Y.
