Normally, you ferment at lower temperatures because your drink will taste disgusting… (there will be terrible byproducts) this article has no explanation as to why this traditional drink suddenly tastes fine with a high temperature yeast other than something about regulators accepting some shit. I imagine that traditionally they they didn’t add commercial yeast… they just opened the top of it and prayed.. and the wild yeast which probably where they live Ferments fine at higher temperatures however, I had to make this all up in my head because there is no fucking information in this entire article and certainly no science and I’m amazed it’s number three. What the is this shit
I think you need to try some kveik yeast, that might change your mind on high temperature fermentation: kveik is a Norwegian yeast, somewhat recently (last 25 years) rediscovered but brewed with for centuries, and can handle 37ºC without the byproducts.

He's writing an essay on why they are wrong.
"But here's the problem - when seeing code like this, somebody somewhere will invariably propose the following "optimization", which replaces what they believe (erroneously) are "conditional branches" by arithmetical operations."
Hence his branchless codegen samples are sufficient.
Further, regarding.the side-issue "The second wrong thing with the supposedly optimizer [sic] version is that it actually runs much slower", no amount of codegen is going to show lower /speed/.
Well, it went too far in one direction and now it’s gonna go too far and the other direction and I guess the only people we have to blame and the only ones who care are the ones who cared
A good 2.5 inch RC car is 30 bucks on AliExpress now, A standalone 5.8 GHz analog camera is 25 bucks.
Just for those that may be more interested in the outcome than just a fun project to do
A standalone (you mean AIO) camera with a builtin VTX is generally even shittier than regular analog, and you still need analog goggles for it. For anyone who doesn’t need prescription glasses or wears contacts, DJI O4 ‘lite’ with the N3 goggles is a much better idea.
You don’t need goggles you can just get a receiver for your TV… or any screen.. also
Qualify shittier do you mean the range of the antenna? A 2 1/2 inch car it does not go outside, so not relevant. If you mean the camera well buyer beware i guess the ones I got were fine. Also, I thought we were comparing this to a cheap ESP 32 build and not some top-of-the-line digital thing the SP 32 build is gonna have a terrible lag. You’re not actually gonna be able to race your friend with it… my setup is cheap and has low latency. no one is gonna buy top-of-the-line DJI crap to race a 2 inch car around their basement
Top of the line would be Goggles 3, N3 is the budget line and it costs less than analog goggles. Maybe with cars it's different, but nobody flies with a screen - the immersion just isn't there..
Depends on where you are. Where I live, it's cold seven months out of the year so keeping the resultant heat inside the house lowers the heating bill somewhat.
I've always wished for a fridge that was mounted to an exterior wall. In the summer, it operates like a normal fridge but with the condenser coil outside of the house. In the winter, the compressor system turns off when the outside temp goes below a certain value and little door/shutters with fans regulate the temperature of the refrigerator either by letting in cold air from outside (if the interior needs to be colder) or from the inside (if the interior needs to be warmer to prevent food from freezing).
There's probably a few good reasons why this is not actually practical but I'm tempted to try something like it in retirement.
Aside the complexity and standardization needed for building it, which alone will absolutely not make it worth it, you'd also have the problem of temperature fluctuations. You probably don't want your milk to be frozen right? ;-)
So if you really need to push indoor air inside to avoid that, you are basically killing the efficiency. And not only that, you would push warm and comparibly humid air inside the fridge a lot. It will condense and now your fridge has to deal with a lot of condensation and probably get moldy.
But good to see that I'm not the only one making these thought experiments.
My personal conclusion is: eventually we will have a single refrigerant distribution system where other systems can be connected and then make use of it (similar to multi-split ACs, but extended to more devices). Then, your fridge would just be part of the system.
And, just to understand: transferring heat from inside the fridge to the outside in the case that the outside is colder is so energy efficient already, there's no need at all to optimize anything. A solar panel as big as your hands will be sufficient even in winter to take care of keeping the fridge cool. That's how little energy is needed.
An energy star fridge uses about 400kWh/year. In pittsburgh, we have 5710 cooling degree days and 736 cooling degree days. Those cooling degree days are spread across about 4 months. So we only need to dump heat from the refrigerator about 1/3 of the time: 133kWh. With an A/C CoP of 5, that means that cooling the extra load from your fridge costs you about an extra 26kWh / year, or about $5.
On the heating side, it's actually better to heat the house from the fridge than to burn gas - you've basically got a heat pump system! Heat pumps are more efficient than direct heating. If you already have an efficient heat pump system this may not be as true but it probably comes out in the wash.
The physical modifications to the house would have to be very cheap to make this cost-effective -- and more penetrations through the house envelope create opportunities for leaks.
Oh man I just watched that whole video. What a ride. I loved that tossing your cigs in the driveway was the correct solution, instead of dip on the front porch. Also the maid taking the service guy’s hat and coat.
That's actually commonly done in industrial cooling applications with rapid turnover (think dockside food storage warehouses), but it's not practical for the heat output of domestic units.
Even in parts of Europe and Iceland with ready access to a common municipal heat exchange, household refrigerators don't have have enough heat output to justify the infrastructure.
The typical domestic fridge just needs to "get cold once" and the remainder of its duty-cycle (aside from the rare holiday feast or party) it's just trickle-cooling.
AFAIK, that's how lots of restaurants keep their stock chilled, at least in my area. They have relatively noisy exchangers outside connected to their fridges that are indoors.
During pregnancy the mothers immune system is muted, which prevents "rejection" of the fetus.
However, in an almost "parting gift" fashion, the departing fetus actually leaves behind immune cells that can provide years of boosted immune activity.
