    They can take either; waiting for confirmations is only a matter of reducing double-spend risk. In practice, seconds after a transaction has been signed and broadcast, it is alread…

    Counterweights provide a constant force, whereas springs can be precisely balanced to the decreasing weight as the overhead door becomes more horizontal. It is inherently related t…

    They can write whatever they like; state law dictates how it actually proceeds. In my state, you must start with arbitration but you have zero obligation to accept that decision an…

    The premise is flawed because that assumes the samples they are studying are identical. Replication is difficult, and particularly difficult for novel processes where the important…

    Benthy, maize, and arabidopsis are the three major plant models. Hundreds of labs specialize in benthy, thousands more use it. It is absolutely a model by any conceivable definitio…

    Most people grow sweet corn in their gardens, so they won't be growing these. There are heirloom sweet corn varieties, but they have to be cooked in minutes/hours from harvesting t…

    What they're really after is using the structure to direct the wind and create stronger flows by the lip of the roof. This is not a new idea, but perhaps they have hit on a shroud …

    > efficiency of 42% of Betz limit, which is inferior to standard utility-scale turbines That isn't surprising at all; wind generation scales very very well with larger size. If it …

    It's just starting to kick in. Most miners stuck it out to the bitter end. Hashrate was only down around 20% from the peak at the switch to PoS. Then it takes a few days to take ap…

    They usually undervolt/clock the GPU, but not the memory. VRAM temps can be an issue and only some miners will try to address that properly with copper shims, etc. The 3090 is noto…

    In theory you could take some percentage of hydrocarbon production and store it to reach zero.

    Replication is far from trivial. It's still worth pursuing, but it's easy to overlook how challenging it can be to successfully execute scientific procedures. Labs generally specia…

    Depends on the card and situation. If 3060ti performance is plenty for you, how much would you expect to save on a 4050? Probably not much, and those cards won't be out until next …

    The idea of an oppressive scientific elite is a bit too neat and tidy. Certainly there are banal human politics at play, but it's hardly an explanation for all that ails. This idea…

    You misunderstand. We've being doing genetics for decades. Molecular biology without mutant studies wouldn't exist. It's the foundation of the field. All this is is a difference in…

    A gene is essentially defined as having a gene product, either an RNA or protein. So yes, all genes are functional. Genes that aren't translated into protein sequences (noncoding g…

    Forking is absolutely central to cryptocurrency. In the end, these are just rule schemes for interacting and communicating about value. If no one chooses to participate in it, it h…

    Electricity doesn't have a thing to do with this. Maybe you're imagining those fancy Japanese toilets that sing to you. A bidet is just a spigot with a valve. Open valve, blast ass…

    Mining economics depend on the mining reward. It doesn't get bigger if more people mine. The rewards just get spread out over more/larger participants until profits are tiny via di…

    Applied Science did a video playing with one. https://www.youtube.com/watch?v=KdfHVcU8U7U There are some significant limits on what it can analyze, but it's terrific for learning a…

    EBMUD actually uses the Pardee Reservoir. But it's a trivial distinction because it's just upstream of the Camanche, both getting water from the Mokelumna watershed.

    Chlorine yes, Chloramine no. You need to know what your water utility is using, and be aware that it can change from time to time. Sometimes they'll use Chlorine most of the time, …
