Can’t wait to see what they release. There is apparently so much doubt against them that this isn’t even news. Like nobody knows or cares this is happening. If this was listed on polymarket it seems this would be trading at like 5 cents. I’d buy it too purely bc I think that’s way too cheap. No idea if that independent evaluator is legit or not. If true though wow what a game changer. I’m pulling for them.

Do the db guys at your company help you optimize queries and table set up at all? Ours basically don’t at all. Their job is to maintain the db apparently and us devs are left to handle this and it seems wrong. I’ve been partitioning tables and creating indexes the past few weeks trying to speed up a view and running explain analyze and throwing the results in Gemini and my queries are still slow af. I had one sql class in college, it’s not my thing. Seems like if dbas would spend a few minutes with me asking about the data and what we are trying to do they could get this guys results relatively easily. Am I wrong?

“Manipulation” is what? You want to create a rule that says a firm can’t buy more than x shares/dollars/% in a certain amount of time? Or if it does it has to hold onto those shares for a minimum time? A firm should be able to buy as much as it wants, subject to its margin requirements, and then sell whenever it wants, be it one second, one minute, one hour, one day…later.

I’m not sure you are seeing it clearly..or have any trading experience whatsoever. They took substantial risk. There is always someone bigger so if they were wrong they could have been buried. Then they reversed. If there are allegations of insider trading or collusion or something else then I’m ready to pile on but I don’t see anything here.

Grid-tied inverters only push power if it senses the grid. It’s a standard feature and has been around for years. Off grid inverters push no matter what. The situation you fear is somebody not knowing what kind they have and just plugging it in.

Can you share your before and after bills? How long til you break even? What happens if you push 800w but your home is only using 300w? Without a clamp on main panel I don’t think it’s smart enough to know to push only 300 so does 500 go to the grid?

I’m confused what ecoflow says. The Utah law says it must be a UL certified device. Ecoflow says something about not needing to wait for UL standard. Are they talking about the same thing? Or is ecoflow saying don’t need to wait for a UL standard for a receptacle but their micro inverter is UL certified?

There was an article in the LATimes article a few years ago with the former ceo of Ticketmaster who explicitly confirmed the above. Ticketmaster does a deal with the band to charge as much as possible and take all the negative blowback or whatever about it and then gives them a kickback.

New comment by futevolei in "I nearly died drowning"

futevolei — Thu, 18 Apr 2024 01:44:31 +0000

I nearly drowned in my early 30s surfing in conditions that were the biggest I had ever experienced (double to triple overhead). On the skills vs risk chart the author mentions I was low-mid skilled in a higher risk environment. I grabbed the first wave of a large set that rolled through and ended up wiping out. Somehow in the washing machine my leash lasso’d around my legs making them virtually worthless in my struggle. Imagine swimming without legs…it doesn’t work at all. The set waves behind mine were crashing over me and keeping me under. This particular storm was angled perfectly for my break and was very strong at a relatively close distance meaning set waves came in groups of up to 10 as opposed to the normal 2-3. I don’t know how long I was under. My struggle was intense. I feel like the entire time I was thinking clearly but only bc I didn’t have time to panic, maybe? Like the author I thought about my family. I remember being close to the surface once and then getting pounded again. Then an extreme calm came over my body. My vision went black and I remember thinking “this is it, it’s time”. Next thing I remember I surfaced… maybe it was right after I thought it was over, maybe I passed out for some time? Like the author I pretended to just shake it off like no big deal. I told the story like a badge of pride, showing fearlessness and strength or whatever. Never once did I say I was stupid for being out there in the first place. But I was almost that idiot that died after saying “hey y’all watch this”. I do hope my eventual death feels like the calm that came over me here though. I’ll never forget how peaceful that felt…

For real. I’m trying to diy a battery now with 304ah lifepo4 cells and it works out to 125wh/kg. Doesn’t seem like even 300wh/kg will trickle down to the public anytime soon.

futevolei — Mon, 25 Dec 2023 21:22:41 +0000

I’m sorry for that painful price drop you experienced but that is on you for paying 70k, a price that literally and explicitly was jacked up for the purpose of decreasing demand in order to resolve the order backlog at the time. Don’t forget all other car makers were doing the exact same thing at the time so this isn’t a Tesla specific issue though Tesla was probably the most extreme.

Walnuts are where it’s at (but agreed pine nuts are clearly the winner). Homemade pesto with homegrown basil was a revelation in our house. Better than any store bought and a fraction of the price.

I’m 45 and only realized this a few years ago and I think about when my dad was 45 and it’s obvious he had no clue. He was all work, work, work, don’t complain, no crying, no weakness. I know he tried his best but man what a screw up…I’m thankful for my wife and friends who put up with my complete and total lack of maturity for so long. Like wow, what a heavy lift I threw at them and still do because I’m still not caught up and not sure I ever will be?

For real, especially considering since I contributed to the kickstarter or whatever. I’ve dm’d him once or twice over the years on Twitter asking about it and no response.

Did you ask about the bill in winter before signing the lease? It’s a standard question before signing a lease in Chicago. Are you otherwise ‘getting a deal’ on rent and now you know why it was a deal?

A friend who does business with them said if the sec denied them they would file suit (check). If that doesn’t work they will open up a window to let holders convert at nav a portion of their holdings. For the remaining they are considering lowering their fees.

You are referring to mark to market gains/losses and not actually realized, correct? Like jump didn’t actually clear 10 bill in profit or lose 4. They were in early size and let it ride but actually investment was small, do I have it right?

New comment by futevolei in "Carolina Gold was once the most popular rice grown in America (2019)"

futevolei — Sun, 12 Dec 2021 14:45:47 +0000

I agree. I was in South Carolina last week and had Carolina gold rice twice- once in a seafood purloo and again in a broiled seafood combo. Had the menus not made a point of noting it was real Carolina gold I don’t think I would have paid any attention to the rice at all. Since they did I made sure to pay attention and I noticed no flavor difference at all. It might have had a different texture, I can’t be sure. End result is this rice means nothing to me.

My employer keeps hiring more argentinos. It’s a few notches better than India IMO but is not without challenges. It’s still a few hours time difference and the language issues remain. Giving them well capsulated or boilerplate work seems like a slam dunk but if it’s code that we need to work with as well then it sucks.

I get this and think this is most likely scenario as well but at the same time this is equivalent to just getting your app started on the box and loading data or something correctly. It’s a step and you’re happy. These bitcoin guys just got their app to start up with limited functionality. They are happy.
