Does anyone have any experience/knowledge with mourning dove nesting behavior?

The top left platform was used continually during the nesting season the previous two years after I built it. I think I had 4 successive pairs of fledglings each summer.

At the beginning of this season, in may, the first fledgings were taken by crows. I have a backyard security camera that I was able to watch the action. The nest sits on a beam beneath my pergola and there's not enough vertical space for a crow to land, but one managed to figure how to basically fall from above and land sideways and get his head in there to grab a baby dove before completely falling down.

The nest has been scoped out by crows before but this was the first time one was taken.

So I built the lower right one, which puts the nesting area about six inches back, hoping it will be enough that the crows won't be able to get them. But it hasn't been used at all this season. Doves will occasionally check it out for a few days in a row. One pair even began building a nest but then abandoned it.

Also not shown is a small roof above the pergola I built to protect the nest from rain. I also made it a tiny bit bigger as the mentioned Crow was trying to get his face between the pergola slats but couldn't reach the squabs. I'm also hoping this slightly bigger roof makes the platform more hidden from predators.

I don't really want to reduce the size of the roof because of the crow issue.

So why was the slightly smaller platform so successful, and this one isn't? Any strategies for attracting doves to nest?

I'm a very amateur programmer and recently started learning rust. I started reading the standard rust book but was browsing Amazon for some other books. I'm seeing so many books published in the past year or two. I bought one:

Functional programming with rust by Danny Lehman

It is self published with poor formatting and layout. The language in it is rather repetitive and I'm suspecting it is mostly written using AI.

I found one specific author, Julian Lornfeld, who has nearly 50 published books on Amazon in the past year..

I didn't have hot water last night. Checking the water heater, the LED on the front wasn't blinking which meant it either wasn't receiving power or the pilot light was out. It's an AO Smith with a Honeywell control unit on the front as in only about 5 years old.

No breakers were tripped, so I was confident it at least had power, though it's a bit annoying that there's no obvious light on the box to demonstrate it actually does have power. I followed the procedure for relighting the pilot light several times and LED would not start blinking normally. My stupid water heater is behind a door in a tiny room in my garage with my furnace / HVAC stuff. Because of the cramped space, I could not actually look through the small window at the bottom of the water heater to see if the pilot light was even sparking.

So I found a small mirror and set it up to get a view inside the window. After turning off the garage lights and some awkward positioning, I was finally able to see the tiny flame when following the lighting procedure. So at least that was working. But the pilot light would never seem to catch to make the system operate normally. The flame would go out immediately after releasing the pilot button.

Watched a bunch of youtube videos and returned to the task this morning. Possibly an air flow problem or ignitor safety reset. Safety reset thing wasn't tripped so I tried to clean all the filters and retried the procedure. Same outcome as last night with the initial flame from the ignitor but no normal operation. I was about to give up and call a plumber, but decided to watch one more youtube video, which demonstrated measuring the voltage from the wires at the front of the unit to test for a defective something or other.

Found my voltmeter and detached the small connector on the front of the control box to measure the voltage. The voltage went up past 350 mV as expected. So at least that part wasn't defective. Though that meant I had no more ideas, so again was about to call a plumber, but plugged the connector back in and gave the procedure one more go, and it TURNED ON!

I have no idea why, maybe there was some sort of reset that needed to occur that happened when I disconnected that small connector. Took like 3 hours of troubleshooting. We'll see if it stays on.

I want to incorporate some vegan meals in my diet. I'm not a vegan, but want to start eating less meat and dairy to lower my cholesterol. I do a bit of strength training, so would like to still get sufficient protein.

I regularly do curry in my large crockpot using chicken because it is an easy meal prep for 2 weeks of lunches. How does tofu do in a crock pot?

I'm also looking at some vegan chili recipes for the crock pot, and again, thinking about throwing some tofu in to increase the protein.

I lean towards tofu as a complete protein source. Though to be honest, I'm kind of ignorant about vegan sources of complete protein, so maybe others have better recommendations.

Somewhere online I read that tofu might break down in a crock pot? Is this true? I might be okay with this because the other potatoes, beans, veggies etc should be enough texture. Unless it turns super gross?
