Visited your website but I don’t speak that language so I couldn’t understand it, but looks like you use a method similar Nelson and Pade…? One thing we did to increase rev per area of space was inoculate wood with mycelium and hang it above the water. You could harvest market desirable mushrooms along with your produce and protein. Also, incorporating shrimp to further add to the process of breaking down the ammonia particulates during the transformation to nitrate can be beneficial and another rev stream. Are y’all profitable and scalable with the ops you’re running?

I’m kind of bummed because I was hoping there were going to be a lot more people focused on this and scaling it, but in this thread there are not…
There are mega churches in the US which push the prosperity theology https://en.wikipedia.org/wiki/Prosperity_theology
Many of their pastors make several million USD every year.

Also, There is a strong overlap between conservatives and right leaning politicians.

So there are money and power motives
There already is a lot of pumped storage. It's the most important energy storage technology today.

The biggest problem with it is that you can't built it everywhere.
They generally found messes and left messes, sometimes better sometimes worse (depending on who you ask). You didn't think the Middle East, South America, Africa, subcontinent etc everyone just sat around singing kumbaya until "colonialists" came along did you?

The "noble savage" is a thoroughly debunked, backward idea.
I resisted for a long time, but the reason I use instagram now is that some of my friends have moved to that platform. So I’m sort of split between fb and instagram now. Also, I like checking “stories” on instagram as you get a quick glimpse of what people are up to and you can send them messages to react instead of writing a comment, which is more likely to lead to a real convo.
Nothing wrong with that. It's how we got good at building skyscrapers too.
It's hardly a space war, space race would be a much more fitting title. And it's hardly dystopian, for dystopian you don't have to go as far as space.
Musk has a ginormous 120m dick though..
I like that to comment you have to send them a message also, ends up leading to a conversation as opposed to comments on a post.
These are now distant times for us. Back then, the overall tolerance for loss of life among pilots was much higher. Not least because there were either active conflicts going on (Vietnam) or very fresh memories of other conflicts with large death toll (WWII, Korea).

I don't think that the first astronauts were as expendable as paper tissues, no, but their level of expendability almost certainly exceeded the norm of 2021. We are being much more careful now.

Even civil aviation was much less safe than today and the expectations of deaths around anything that flew were simply higher.

As far as obedience goes, I can believe that test pilots are on average less obedient than an average member of the military. They might be better motivated/manipulated through feelings of national pride etc., though.
You don't need RAM to serve map tiles: Tilemaker and similar can produce the tiles to be served as static files. You can also find pre-made tile sets you can serve.
In many countries, Engineer is a protected status job title. In the US I believe "Professional Engineer" is protected

In the US, going to school to become a Graduate Engineer does not make you a Professional Engineer.
>Where is a country like Ethiopia getting all the money for such a mega-project?

The cost is $4.2 billion according to the article, and Ethiopia's GDP is $272 billion. It's not a mystery to see the project get financing, though I imagine the risk of war warped the deal somewhat.

Curious, is there any promising open source work in this area?
Is there any interest in such kind of "flight" except from some kind of fun/tourism for rich people? Will it provide something in the future, like a first step to something or is it just that? It seems to me that this kind of activity has no scientific interest and no next step. Am I missing something?
Everything that implies taking sides is politics, no matter what.

The one SkyMall i remember from a US flight ages ago was one for shoes with springs built into the heels which claimed they would make you walk faster. Deciding whether the whole magazine was a witty caricature of US capitalism or honest advertising took me a while. I then decided to keep the magazine as a souvenir but have unfortunately lost it since.
Something I found interesting in the emoji usages in China:

1. In Wechat "emoji" is a superset that also includes memes, where you can use any kind of image as an emoji also add other's emoji to your library (kinda like slack emoji, but bigger and more emphasized). The humor and expressiveness is immense, people use them for daily conversations instead of a quick reaction tool (well that too). Everyone's emoji lib is vastly different and it says a lot about you as a person, it's almost like a personal language.

2. The "Smile" emoji in Wechat actually means hostility [0] in younger generations ("it could mean that you just said something really dumb and the sender doesn’t want to speak to you"). Some older generations folks don't "get" it and still use them for good intent. It's always weird to see your parents send you that.

It is quite funny that in Germany every energy hungry industry is looking since the last decade to produce flexible enough to benefit from negative and cheap electricity prices during certain periods. Examples I know of first hand are graphite kathodes and electrodes (the process can be stopped for hours as long as temperature doesn't drip under a certain threshold) and paper. Continuous chemical manufacturing is having a harder time so, but they are looking into ways to store process heat for later use and generating needed heat for storage. Nothing came from that at on of previous employers so.

Funny is that these same companies, already now making a small fortune from these initiatives, are complaining about electricity prices and base load stability.

One of the best complementary sources to renewables are, besides existing nuclear plants, modern gas turbines.
Performance was not the selling point of relational databases in the first place. It is hard to beat the performance of a perfectly tuned hierarchical or graph database on the workloads they are designed for. At best a relational database can be equally fast. For this reason hierarchical/graph databases never went away and are still appropriate for specialized tasks.

The selling point of relational database is they can accommodate long-lived multi-purpose databases used by multiple different users and applications over time and where the data model would change and evolve over time as the world changes. The is achieved by "data independence" - the logical model is decoupled from physical storage structure and is not hard-coded to accommodate particular query patterns. So you can have ad-hoc queries - cross-cutting queries which you didn't know you would need when the schema was designed. The key insight is that relationships between entities are also just data.
Or you can get home batteries LiFePO4 chemistry. Better lifetime/more cycles, requires temps about 100C higher than NMC chemistry to hit thermal runaway, and better temperature ranges. The only problem is that it's not as power dense as NMC batteries but that's not a huge concern for a home battery.
It's worth noting that the EU-paid study was done in 2013, back when streaming and YouTube was on the rise. Billboard called streaming unignorable in 2013.

Well, the original topic of this discussion is water scarcity, and that is determined by absolute # of people living in the Nile basin. Not by just TFR. One can argue that in order to achieve sustainable levels of population, the TFR should have dropped much more and much earlier than it actually did, and discuss the reasons why the decline wasn't as fast.

After all, with the concentration of people in the Nile delta, everyone had to be aware of the fact that their country is becoming dangerously overcrowded by 1990 at least. Possibly sooner.
Again: problem with plastic pollution isn't climate-related, it's about (hypothetical! [0]) food chain poisoning. Disposable plastics are just a tiny fraction of petrochemical industry's emissions.

Yes, as hairdressers are dealing with sometimes extremely toxic or allergy-causing/-triggering chemicals on the skins of their customers.

Hair color and bleach is nasty stuff.
The way I see it, "work time" is usually quite a big chunk of a person's life, especially if you throw in commute time. It also tends to take out the most "useful" time of the day.

Want to go hiking? Swimming in a river? Build some furniture? Build a house? Watch birds? Go shopping? Wrench on your car? Race your motorcycle? All are best done during the "work hours".

So while I can see the appeal of not tying one's meaning to one's job, I also completely understand the sinking feeling of having to postpone these activities for doing... nothing.

Because even though you can "find something to do" while at work, most of the time, you're not fully free. You may not just pick up your stuff and go fishing. You have to stay physically at the office and sometimes even have people dropping by asking random questions. So even getting engrossed in a book / music is out, since you'll be randomly interrupted. At least if you're WFH you can do random chores to free up the time afterwards (do the dishes / laundry / bake a pizza).

Of course, if you have to work to live, you have to go through this. But I don't see how its being necessary can make it less soul-crushing. Quite the contrary. I'm lucky enough to be able to find things to do on my own, or if not, work for one of my hobbies which happen to involve computers and don't require me to be physically somewhere precise. But not everyone's so lucky.

I can guarantee Branson's carbon footprint is going to be several orders of magnitude larger than yours or mine.

You might argue it is insignificant on the world stage but these things are symbolic. It's going to be hard trying to convince people to lower their footprint when they see the rich and famous behaving as if there isn't problem.
Very little. SpaceShipOne/SpaceShipTwo/WhiteKnight* are interesting craft. Real commercial usage of a hybrid rocket engine is new. And 'LauncherOne' is slowly proving itself capable of orbital launch of small sats from a carrier aircraft, like Orbital did with Pegasus.
In my experience, yes.

I can load .apk files directly onto my device, without using Google Play Store, which is optional.

An Android device has NEVER locked up on me, demanding "activation", which then makes me wait 10-20 seconds before timing out and not working. (Happened two different devices, and that's just recently, and one I was not able to recover.)

I can install different versions of Chrome, Chromium, and even non-Google browser distributions and engines like Bromite, all independent of the OS. Bromite is the only mobile browser I know which has a "View Source" command in the menu. (No, adding "view-source:" to the beginning of the address bar using kludgy cursor control and text entry, is NOT workable.)

I can even get a command prompt with a GNU/POSIX environment and bash.

And I can sort-of kind-of access the file system with a whole array of different tools.

All on every stock device I've ever tried. I recently rediscovered a 2013 device with Android 5.0.1 on it, and I was able to install the latest Bromite on it. It's now my daily driver.

I would say that's not just better, that's MUCH better.
The term Engineer is pretty much meaningless in the US. The IT trade is pathetic in this area -- if you swap out a few cat5s you're suddenly an "Network Engineer". Cut and paste some stackoverflow snippets together and you're a "Software Engineer".

In the UK the term is meaningless too, but CEng isn't. You don't become a Chartered Engineer until you've done the education but also have monitored professional practice experience.
Well, maybe I should be more optimistic and someday businessmen will zip to their destinations on tickets of a couple thousand dollar, or in their own private spaceliners. But a real democratization? Okay, I'll leave that open as remote possibility :)
Because the last commit date is a key indicator of activity in a project, and someone who is archiving a project doesn't want to get a viewer's hopes up.
No one believed me when I said this happened, and further password resets tidied it up and I decided I was just wrong.

It seems I wasn’t.
When I went to senior high back in the early 00s I shared a flat with three friends. None of them had their own computer. I had a spare IBM PC with an old Pentium processor which I lent to one of my room mates. I installed Debian, IceWM and Abiword for her. She had no previous experience with Linux, but with this setup she was able to write her school essays and save them to floppy in order to print them out at school. (We didn’t even have a router in the flat.) It worked really well and was much more stable than Win 98/XP :)
Since you mentioned this was your first serious project and some others were giving advice: in the future, I would recommend using snake_case rather than camelCase for Python projects. Not due to any subjective feelings about it, but just because that's the idiomatic Python convention. It's what the standard library and almost all third-party libraries use.

snake_case: Python, Ruby, Rust

camelCase: JavaScript, Java, C#, Go

The build log I linked to is in English. We will also publish more in that if you want to follow it.

This is a pilot facility, but looks similar to what Nelson and Pade offers at a quick glance. The commercial scale facility will be very different than this. The scale is 50-100 times larger and you can think of the growing area of this as one layer in a multi-layer facility.

This small scale pilot is far from profitable. Generally we think you need to be at up to 1000 m2 growing area if you have a facility which is a side business and you take care of it alongside your farm. If it is a business by itself with external distribution you probably need it to be about 10 000 m2. (Of course this depends heavily on your local conditions, what you can sell, at what price etc.)

We are focused on scaling, but that is another story than a demo and pilot plant. :)
Well, these situations usually involve you having to be physically present and won't allow you to be out of office randomly for hours at a time. So that limits the kind of second job you could take.

Also, many people work on fairly locked down computers with nothing much to do aside for (filtered) internet and random "corporate" apps. I'd be quite surprised to learn that in these kinds of situations, where people are required to be physically present to do nothing, they would be allowed to bring in their own computers and openly do private stuff.

Google business is built on using your data, it is truly an Ad company, while Apple is not. And common perception of Android as open source, it is not. Google Play Services runs all the time and is closed source.

"Downvoted for the personal attack on the author"...

Yes, well, I've had it with charlatans in this industry; in every other profession, professionals take on responsibility for their actions, just in information technology and computer industry, almost everybody hacks, builds crap and takes responsibility for nothing. "We never point fingers at people, just at technology..." Yeah well guess what, that technology was "invented" by people, usually one person. When there is personal responsibility in the game, maybe the people responsible will stop reinventing the wheel and start producing small, fast, simple, high quality software...

If you spout nonsense, I will call you out personally for it, as I do not suffer fools, since my patience has worn out: enough with the kindergarten for adults already, that has to stop as well! Take responsibility for what you spout, bear the consequences. Enough with crap technology and constantly reinventing the wheel!

There is no need for JSON in the first place: a flat UNIX text file, delimited by colons or pipes and streamed as an input to another filter or the final program does just fine. So the premise that it has to be JSON is already broken, and anyone who doesn't even question that premise has already missed the elephant in the room. Ergo, if the author is even considering solving the problem so that it would fit into JSON, then the author lacks insight, and if he or she lack insight, then they are not equipped to solve the problem, which in the end, quite unsurprisingly, they do not solve.

Why am I so much against JSON? Because not only is the format ill thought out, but constructing a reliable, robust parser for it is a technological nightmare. How then is this a better solution? How is it a more robust one? How is it a simpler one? The answer to all three questions is quite obvious, at least to me: it is none of those things.

If somebody who is supposed to be a professional with that level of insight completely misses or accepts that JSON isn't simple, that it isn't robust, and that therefore it is not the better solution which does not better the industry and computer science as a whole, then that person has no business writing, let alone designing anybody's software.
Do you imagine a world in which nuclear reactors are as easy to mass produce as solar cells and batteries?
Cut them up!
Cut them up!
CSP (concentrated solar power) isn't on the same price reduction curve as photovoltaic solar though.

But at grid scale there are lots of options for storage. Pump solar is the obvious option.
Edgedb seems very nice.

Is there any plan currently to give back to postgress? If this is already the case, was there anything going upstream from your team?

These kinds of studies should always come with a trigger warning: "Be aware if you are emotionally distressed when your belief in the Just-World-Fallacy is threatened."

Joking aside, having grown up relatively poor and feeling compelled to put work success above everything else to ensure economic stability for my kids these things really do negatively shape my expectations for the second half my life. Not sure what to do about that.

Which is why he uses and advocates for JSON, right? That is so horribly wrong on so many levels, as JSON is an incomplete[1] and completely unnecessary reinvention of a wheel, just because the dispstick who invented it didn't understand that the problem could be solved with flat UNIX, plain ASCII files. "Wait, what is this UNIX thing, is that something to eat...?"

Like Paul Graham wrote, "So it's easy to launch a devastating attack on a new idea, and anyone who does will seem clever to those who don't understand this asymmetry."[2]

While SQL is by no means a new idea, it was easy to shit on E. F. Codd's work, but I don't see a better solution proposed by the author of that essay!

To the salt mines with the lot, for such people have no business touching programming!

Lego boost has two major appeal to me:

- relatively cheap

- easy to get into

But very fast there was a set of hurdles we bumped in, and the boost hub is seriously limited compared to the twice more expensive spike hub.

- It’s way slower (you won’t be able to balance the most basic structure like two wheels with two motors in an autobalancing loop)

- its sensors can have weird edge cases. For instance the gyro only reads from 0 to 180, so it’s a PITA to use it verticaly

- It doesn’t have recharging optons which makes it a PITA in many ways. Apart from dealing with AAA batteries and their size and weight, you also need to plan your builds for changing easily them as they won’t last long,

- the size is awkward, it’s not a full stud count between the anchoring parts, and matches badly with full technic blocks.

- The programming blocks are cute and all, until you realize there’s no manual nor official explanation of what they do and the params they take, and there’s around 50+ of them.

- at the end of the day it’s Lego, and education is a checkbox in their marketing slides more than a focus. There’s parts that are only available in the spike educational pack. Some only in other sets. You get sanctioned scratch only with the prime hub, the app requires a tablet (phone screen is just ridiculously hard to use), and there’s no way to back up/restore programs (up until 6 month ago at least, I haven’t checked since)

The most disappointing part was that it didn’t feel like a gateway drug to something beautiful (the spike hub ?), more like a taste of nickel and diming, no visibility into the future of the ecosystem, not giving a fuck about kids deeply learning (really, no epxort/import, no block explanations ?)

I feel kinda burned and will wait a while to get back to it in a better state of mind. For anyone getting into Lego Technic, I’d recommand the “my first born and an arm” priced Spike option.
