tcl is what you get when you take shell and lisp, and smash them into each other.

In many ways, its a lisp whose central data structure is the string, rather than than the linked list (so, a sisp?). And instead of macros, you have fexpressions (functions which can decide at runtime whether or not to evaluate its arguments).

When you understand it like that, you can write some elegant code in it. And as it does have proper, efficient data structures under the hood, performance is on par with most other mainstream, traditional "scripting" languages. Although semantically, everything has a string representation - if you're creating a list, and use it as a list, it only exists in memory as a list (as so you dont pay performance costs of auto-casting to and from its string representation).

2 things really tick (goes with tickle, I guess) me off though:

1. because everything has a string rep, its hard to write code which can handle polymorphic types. For example, say a parsing routine which can take either a string, or a list of strings.

You end up having to 'tag' your data somehow (basically, roll your own static typing), which just feels wrong in such a dynamic language.

(could just be my deficiencies in using it, though)

(on the plus side, rolling your own tagging system using tcl ensembles shows just how malleable the language is. You can almost turn it into anything)

2. the parser could do with some changes. Too much tcl code just looks ugly because you (well, I) can't indent it the way I would like. So you (err, I) end up with /'s everywhere.

Bottomline: tcl is so close to being the perfect drop-in replacement for bash (if only the last extra yard was taken) that its painful to go back to using bash for, well, anything.
The thing about the invisible hand is that it works really well if you buy a chocolate bar that you don't like. The next day, you won't buy that same chocolate bar. However, when a handsome man in a suit offers my cousin a loan for a house that she can't afford and puts her in severe financial trouble, she might very well not use that bank again the next time she's looking for a loan (in maybe 30 years), but that doesn't help much.

The free market self regulates well in some areas. Others need some assistance.

I didn't cut meat out specifically for financial reasons, or any particular reason really, I just stopped wanting to eat meat. The financial benefits are just a bonus.

Ask HN: Can we deserialize organisms from DNA yet?
Not a specific organism (with its synapses, memories, methylation, quantum state, soul etc), but an "instance" of the species from a "representative, accurate" copy of its DNA on a hard disk.

The question is not "is the DNA accurate enough" (tho maybe that is a thing, I don't know), but if we have "accurate" DNA, can we somehow create a living thing (not knowing how accurate this is, but to illustrate the meaning: print DNA into bases, put these in a cell, somehow grow that cell into the organism). Has it been done?
There is very little, but what I have found is good work from The Math Citadel folks: https://www.themathcitadel.com/category/spire/probability-th... ,, also one in the stats category.
Make sure most of your tutorials are around the language and not specific to some frameworks.

Being able to understand the underlying language has been key to finally get a grasp on what happens under the hood with Modern Magical Frameworks.

Also, being able to understand the event-loop and how JS manages memory etc is worth getting into once you have the basics clear. I recommend understanding the internals of V8 at some-point down the line.

So was I. Fredrick Douglass spoke about the experience of the Negro being enslaved in USA. That was a powerful image. Normally, it would be quite appropriate to point out that people from the same continent, with the same skin, were enslaved also in Arab countries all through the 20th century and discuss the institution of slavery there and how it compared throughout history with the US institution. (Mamluks for example.) It can unearth a lot of interesting and historically useful information. But more to the point, Black people are being enslaved even today, but you would prefer to suppress this fact because why? Because freedom and independence wasn’t for everyone in Douglass time, IN THE USA. And what, only the USA matters?

I am just trying to get you to see that if this was any other topic on HN, like eg a speech by Linus Torvalds about Git, a wide array of comments would be perfectly fine eg someone asking whether distributed VCS has really taken off, or (like I did) whether people still use centralized version control in some companies.

Here we are talking about the lives of human beings. But apparently Black lives matter ONLY in the USA, women’s lives matter only in the USA, because mentioning current honor killings of women in some countries is racist. That is a perverse reaction and no, saying it’s “off topic” just makes it worse. You either don’t actually care about women's rights or ending slavery, or there is some overriding principle I am still not aware of that makes the same exact issue outside the USA so off topic as to be essentially unwelcome as a comment!

Meanwhile, solar appears to be leaping forward in China. From the end of the article:

"All the while, nuclear is falling further behind renewable solar and wind power. As Schneider notes, the 3.3 GW of new nuclear capacity connected to the grid worldwide in 2017 (including three in China and a fourth in Pakistan built by Chinese firms) pales in comparison to the 53 GW of solar power installed in China alone. "
Because there are serious costs to bringing everything in-house; you've got to get hold of the capital, you lose any economies of scale that come from addressing a larger market, etc.

With regards to transportation costs, you're assuming that a restaurant running a private vertical farm could do so on its storefront premises, which is a big assumption. Most pricey restaurants are space-limited.
Every time I read an article about vertical farming its always leafy greens, and very occasionally strawberries and tomatoes. It doesn't seem like vertical farms can grow anything else
You are never going to beat the efficency of the sun shining down on plants for free, no matter what. I mean the entire idea is absurd, what are you going to have solar panels on the building that somehow collect light and re-emit it, and have that be more efficent than just the plants collecting the light directly?

So you take more land area for solar, why wouldnt you just plant crops on that land area instead...

As a commenter on the same top-level comment noted:

"The investors funding these enterprises do not understand agricultural economics. I keep investigating these stories looking for some kind of 'breakthrough tech' that would dramatically reduce costs or increase yields. I've been tracking these vertical greenhouses for fifteen years, they open and a couple of years later they're gone."

Higher productivity per watt in the broader industrial sense does not equal higher productivity per watt in the smaller sector that is agriculture.
How'd you figure out which solution was the lowest cost? Because if subsidizing these power plants was the lowest cost, that would probably be already happening. Normally grid operators use an economic model (including huge penalties for blackouts) to pick the solution with the lowest cost. Batteries are cost-effective in the short-term, and natural gas storage is cost-effective in the medium-term. Subsidizing expensive coal and nuclear is not cost-effective at any timescale.

Add a carbon tax, then maybe nuclear might still make sense.

That energy and equipment is priced a lot better than land use, on average.
I've seen this phenomenon almost everywhere. A lot of times it kicks into high gear when "the powers that be" start making big, dumb changes (though often times they don't seem quite so bad in the moment). The best talent with the most important experience evaporates.

The thing that is the most pernicious about this effect is that it can be difficult to notice objectively. People who are in the trenches, are clueful, and know first hand the qualities of individuals who leave will know immediately that this is a bad development and that the organization has lost something of significant value. Even so, it can often be difficult to back up that gut instinct with factual evidence. It often takes years for it to become fully evident unless there's utter incompetence on display, and that evidence is usually in the form of it being more difficult and taking longer to execute on challenging projects, while achieving less success as a result. The thing is, in almost every dev shop on Earth and especially in the "higher level" ones the projects from year to year or "release cycle to release cycle" are often not 1:1 comparable, each has their own unique difficulties and complexities and even without losing any talent it would take a different amount of time to tackle those projects and the results and "level of success" would still be different. Without a window into a parallel universe it's hard to say how much you've fallen behind the nominal "unevaporated" track.

And in the eyes of management it's even more difficult because they are even more resistant to the notion that something they've done has had a negative impact on the company. If the end result is anything other than abject failure, if the lower quality "dead sea" org is still able to achieve a decent measure of success, still operate a profitable and successful enterprise, and so on, then they will think everything is fine. Even if the difference might have ultimately been orders of magnitude difference in levels of success, because that alternate timeline is unknowable.

And if you wonder why so very much software is surprisingly mediocre despite many hundreds, thousands, or tens of thousands of dev-years of work being put into making it better, well, maybe there's a reason for that.

> ‘interchangeable code monkeys’ mindset

Which is pretty much the default mindset these days...
I've actually started mastering this technique and using it where it makes sense. When a salesperson tries to get you - always be a buyer but a buyer of something they aren't selling. I think it's like the Benjamin Franklin technique where you build up immediate rapport and control by getting the other person to do something for you. So by asking for something it's like saying "parlay" in Pirates of the Caribbean. It stops them from their normal process.

Example: on the Vegas strip they always have people selling strip clubs and pestering you. I'll say "can't do that tonight but do you have any (insert legit magician) tickets?"

They'll go oh man sorry don't have those tonight. Was going to get some, oh shoot. Have a nice night and take care!!!!

It's like the sale that got away. You're still cool to them so they back off.

I do this with the CD artists - don't have a CD player, you streaming? Nah man.

So always be a buyer of whatever they don't have to sell haha.

The company is a small startup with an amazing breakthrough called Optimizing Mind.

They have magical ways of 'explaining' black box models.

But it's not what DARPA is pushing (box remains black), rather the opposite, illuminating what's inside the box, making it a transparent open box. So much so, that the models they make you can edit by hand, since they make sense (to mere humans). Has rather immense implications.

Here's their crappy website: https://optimizingmind.com
Not competitively - the added cost of indoor equipment isn't that high compared to the already-high costs of those products, whereas the competition in bulk grains production is a lot tougher.
The current vertical farming is in its infancy,
sooner or later, new optimizations will emerge that will allow major increases in productivity(e.g. producing only the exact wavelengths of light optimal for growth, computer rationed water supply, advances in genetic editing like CRISPR, better knowledge of small-scale processes when studied in isolation such as their nutrient/energy needs, the selection and study of nutrient rich strains, how plants respond to increases in light/sound/vibration, etc).
The idea that natural environment is optimal for growth is a conservative assumption that we need to replicate it exactly. There many factors out of control with natural environment that we apply pesticides, fertilizers, greenhouses, soil tilling, herbicides and weed removal, etc.
A closed vertical farm environment will allow much cheaper overall control over production process.
I'd say that's less something evolution has and more something it is. Although "overall surviving fecundity" or something probably describes what it's optimising for pretty well.
Sure, if the compiler can find optimizations by inserting vector instructions, it will. But, typically you'll want to specifically format your code using matrices/a library like BLAS to maximize performance and use as many vector instructions as possible.

"I'll make the logo"
One of the smartest thing I’ve seen in the crypto realm was the realization by the Codius folks some years ago that smart contracts are something that would benefit from an “off chain” execution framework/platform, independent of any specific blockchain.

Hence, the cryptocurrency part is purposely orthogonal to Codius. I don’t think it’s tacked on, it’s more agnostic and it’s up to end users to decide what if any blockchain integrations they want.
The potential for Codius (and yes, it is an ambitious vision, with a long way to go) is a framework where you could deploy much more functional and powerful distributed applications than would ever be possible with a blockchain based approach like etherium.
I was speaking in the context of two different frameworks, not code, but I suppose the clarification is nessesary.

> I one worked with someone who changed all i++'s in a codebase to ++i's

Did you use the previous value of i, or did you just intent to increment it? ++i communicate that I'm not interested in the old value, where as i++ does the opposite. I actually use it as such, because my intent to a future reader of the code is more clear.

That said, for complex types, and with "stupid" compilers ++i can absolutely be significantly faster.
