Reply to ELi5 : If you can access a website, why cant you steal the source code and make a 1:1 copy of it? by 13lettersinhere
You can steal and make a copy of the HTML and other code that is delivered to the web browser. If only that is stored on the web server you can make a copy of the website, at least all of it you have access too. If you need to log in what you have access to often is in part specific for you. You can access for example access my Reddit chats
​
The problem is most website is not made by just static HTML files stored on a web server. Reddit, for example, uses phyton code that is executed on the server, and it access databases with all the post, comment, user preferences, etc that are used to create the HTML pages you get and your browser display right now. The website does not give you direct access to the phyton code or the database when you browse the website.
So making an exact copy is not as easy as it first looks like.
​
​
Nothing says the code that generates the website can be published too, you do not need to but it looks like at least part of Reddit is available at https://github.com/reddit I am not sure what is included and if it is complete or not. But I doubt that Reddit provides a public copy of the database.

I didn't learn about imaginary numbers until several decades after leaving college.

Actually if the website mostly is static pages/pictures, you can make 1:1 copy. But if the page doing some backend processing, like searching internal database, processing data, then it is hard to copy the website. For example, weather forecast website

Don't argue with me . . . my opinion is informed by conversations with a PhD who happens to be the Master Blender for J.P. Wiser's in Windsor. Take it up with him.

Only some code is presented to the client on the front end. A lot of the heavy lifting is done on the backend using code that the browser is unaware of.
In addition, most interactions you have with websites involve databases of information. Without having your own similar mirror of data, the code is largely functionless.
Many years ago, web development classes would often have people build a "pizza ordering website", using HTML and eventually CSS - form fields, etc. - but those are just a facade... They rarely actually did anything tangible or saved data anywhere until you got further.
Copying the source code of most websites is going to give you fairly poor results, go ahead and try it, it is basically just stealing the non-working pizza ordering UI, at best case scenario.

Reply to comment by OpenPlex in ELI5: why can't we use electricity to kill microorganisms in small amount of water ? by FreshT3ch
There is less of a distance between a person's two feet than that of a horses front/back legs. Earth, the surface beneath our feet, typically has a high resistance. There is a higher chance "electricity" will choose to flow through a horse, as it has to either travel that distance through the horse, or through the ground. For a person, that distance is smaller, therefore less resistance, and less likely to use us a bridge between two spots on the ground.

Beer has much more to do with ingredient quality and process steps. I can’t speak to Bud vs. Busch, since they are both lagers and have a similar flavor profile (to me). Compare the flavor of, say, Anchor Porter to Budweiser. Worlds apart.

Disagree on both claims.
-
Number of distillations absolutely makes a difference when it comes to high quality vodka. While you are absolutely correct that high reflux columns with lots of plates increases ABV (thus purity) of the resulting distillate, multiple distillation runs result in fewer cogeners in the final product, thus less discernible odor/flavor.
-
Grain makes no difference in vodka if properly (multiply) distilled. You can make vodka from grain, potatos, rice, seaweed, grape juice - anything that can be fermented to produce ethanol. Vodka by definition has no discernible taste or smell. It is very very close to just ethanol and water.

Reply to comment by Diagonalizer in eli5: Why does cheap alcohol taste worse than nicer alcohol? by Chase_The_Dream
I agree. And yes, we do get it in Canada. But we also have better options, as well. My personal favourite in terms of Vodka was a a Dutch Vodka called Van Gogh Triple Wheat.
The gimmick was that they used three different varietals, grown in three different climates (prairie, mountain, and shoreline). It was interesting in that different palates would note different qualities. I tended to focus on a tinge of brininess (sea air), while a friend of mine would note a minerality to it.

You could say "no solution is possible", and for certain starting assumptions that's true, and you can solve certain problems with that. But you could also use the starting assumptions that let you make a coherent answer involving imaginary numbers, and that lets you solve all the old problems and a lot of new ones as well.

I think this video explains it much better than any short reddit reply could, but basically mathematicians historically had a similar opinion compared to yours, until they actually discovered places where this number is relevant and useful (quantum physics).

Ah, so a larger distance wouldn't guarantee a larger voltage, it would merely raise the chances because of changes to the surface being walked on.
Or, wait. No, the voltage difference is because one hoof is over electricity while the other hoof is over zero or fewer electricity, so now electricity will travel through the horse which is electrically conductive.
> The surface beneath our feet usually has fairly high resistance
That's if we're wearing sneakers, right?
Like if one foot were barefoot and the other wearing a sock, we'd create a large difference in voltage?

> So, all air-breathing heat engines (from internal combustion engines in your car to supersonic aircraft engines) require the air to be compressed above atmospheric conditions before you add fuel and combust it.
You can design an engine off the Lenoir cycle (i.e. a pulsejet) that doesn't require compression.

Good explanation. Is this true with like beer beer to? Like why budwiser and bush are basicallu identical but one clearly is better tasting(usually) and cheaper?
I've always heard the better case of bush would taste better than a worse case of budwiser but never understood why.

Grain makes a difference. Number of distillations is a marketing tool, just as Tito's "made in Texas" nonsense is a marketing tool. They truck it in from Indiana (iirc), run it through their own still once, and this is what allows them to claim it's "Texas made".
​
The reason I say that "number of distillations" is just marketing is in the way a column still works. There are plates all the way to the top of a column still which catch the condensate. Technically, each one of these plates can be considered a separate "distillation". So, a column still with 30 plates could legally claim to be "30X distilled)". Not that I have heard of any of them doing that. But no, running it through your column still more than once is not going to significantly improve the spirit. If you didn't get it right the first time, it's not going to get much better afterwards

They really drop that one on you out of left field in higher level math/science/engineering classes. One day, they are just like 'remember that imaginary number bullshit from junior high school? Here is what that is actually for.'

It really is easy tbh. I'm a cider or vodka drinker and have been drinking both since my late teens (25 years now) and I can very easily tell a crap from good vodka even when used with a mixer. I'm sure most vodka drinkers could (that like the good stuff).

Reply to ELI5: Why is charging your phone to 80% better than 100%? by SexysNotWorking
I'm not sure that I accept your premise. If it were really better for the battery, wouldn't the engineers designing the charging circuitry simply force it to stop charging at 80%
