This is why without some future battery revolution, any kind of electric flight will be limited to toys and niches. I suggest to google around a bit and watch some youtube videos to get a clue how many electricity/battery powered air planes we already have. Many of them fly since decades, literally.
All the idiots who want stuff to get done and get payed for it.
It is surprising how ignorant/. readers are.
While the majourity of all big internet software in the USA is written in Java, thy proclaim death to Java all the time. How is the balance between C# and Java in the USA regarding serious back end software? 10% is Python and PHP and 0.5% PERL? And the rest? 60% Java versus 40% C#? No idea just wondering.
In Europe basically 90% of all industrial software on high performance back ends is written in Java. The idiots who decided for C# don't even find developers to maintain their systems. I have requests for C#/.NET developers every day. I would get $1000 for every colleague I would refer to the requesters. Unfortunately I do not know a single person who is so dumb to work with C#/.Net... go figure.
Java is just C++ running on a VM without real templates, anyway. If that is to hard to grasp, you should not be working in the software industry.
Applets where unsecure because the Java Plugins for browsers had bugs. (Because they had to implement more security restrictions than an ordinary VM) That has nothing to do with Java 9 modularity.
and then break reflection (being able to inspect library code from the code using that library). Inspection always ever only worked on objects and classes and not on libraries. So if you have a class loaded from a module, reflection works exactly the same as loaded from an ordinary jar file.
I'm not aware of anything in the Java world that is a mess:D
The stackexchange question you link is simple to answer: because packages and modules are two different things?
Is the trunk of your car a suitcase? Or a pocket in your jeans? Does your jeans pocket have a lock? Does your suitcase have wheels? Regardless of yes or no... are they the same thing?
Laymen don't need to care. For them it makes writing simple programs just more complicated.
A module is a library, aka jar file, that exports a part of its classes, and keeps the other classes private. Unlike ordinary "private classes" non exported classes are basically invisible for everyone outside of that module.
While you can do that with OSGi, too, OSGI is configured via the.MANIFEST file in a jar file and modules in java 9/project Sigjaw are configured via semi Java looking source code processed by the compiler.
Modules can have dependencies and have version numbers, so module x-1.0 can depend on module y-1.2 etc. How the dependency resolution works and how they support maven or similar repositories, I don't know. I did not bother to "learn" that stuff, as it is now postponed to be released since about 5 years.... yawn.
Your rant has nothing to do with Java Modularity, aka project Sigjaw or look at OSGi.
Your reference to SmallTalk is wrong too.
In Java you have a private attribute x, and use accessor methods like getX() and setX(). But if x was public you could write: obkect.x = balls or balls = object.x. In SmallTalk you can not even write that, because it lacks the syntax for it. Hence the SmallTalk IDE/compiler generates you the getX and setX methods... no big deal.
The rest about "modules" you write is utterly wrong.
A module is a jar file, aka a library, that exports (makes public) some of its classes and some not.
When you go to a lawyer, you want a honest opinion. When you go toa doctor, you want a honest opinion.
Google is screewing up search results depending on which device I google, which or if I'm logged in witha google account or plenty of other circumstances.
Stuff I found easily last year suddenly vanishes from its search results.
There is stuff listed in the results that does not even is related to my search query.
And if you want to refer to Bing, bing is such a bad search engine it is close to unuseable. I enter an english search query and it only lists german sites as results because I 'googled' from grrmany.... how brain dead.
Sponsort results in google results or advertizing is clearly marked, no one cares about that. But the order and ranking and weight of search results makes no sense any more... it varies from day to day.
Denmark is what you would call a socialist/communist welfare state. They have a luxury tax on plenty of things, instead of a super high income tax. So what the state considers a luxury good is taxed, regardless if imported or home made. And from that they pay their lifestyle:)
Is the US economy going to be better off without the Paris accord, or worse off? Who knows. As far as I can see the US economy does not follow the rhythm of the world. However every time the US economy has a crash or swing down everyone is fearing it would affect the world economy. Usually it does not. E.g. look at the Dow Jones. Why people believe falling prices for stocks influence the world economy is beyond me. Steel mills have to run... etc. That is completely unrelated to most stock prices, perhaps related to coal and iron mines... Anyway: when stock prices drop my wage stays the same, so do the prices for the goods I consume. Total amount of food etc. is a fixed setting for a society. That might differ for luxury goods. Rents do not magically rise etc. p.p. Perhaps all this is different in USA:D
Come on! Don't be depressive. There are good things about Trump, too! I get dozens of Trump jokes and funny comedian movies about Trump every day on FB and other media, e.g. the latest press release from the white house: "Trump states he was disappointed about his meeting with the Pope. He was only met by Gods proxy".
Sounds like Greg Bears excellent novel "Queen of Angels". He is not explicitly describe the decline of the state and the rice of the cities but it gets clear from the context.
wouldn't they adopt them on their own without... Obviously not, just look at internet speeds and technology and prices in USA. Or the quality of typical throw away american products. People by either cheap and throw away, or a brand and pay premium. Rational "we shift with the cheaper stuff" and "long term _investments_" into high quality goods etc. is not really the strength of the US capitalism.
If you have a large house in a rural area, a boat, and a truck to tow the boat, then climate change policy is a direct attack on your quality of life. Unlikely. You don't lose quality if you have a better engine in the boat and truck, or go both electric or in case of the boat hybrid.
You just prefer to eat more cheap food and get fatter instead of saving some money and upgrade your hardware.
I'm sailing, my boat engine runs less then 20 minutes a day. 10 to get out of the harbor and 10 to get back in. Well, if the sails are tricky to get up, then perhaps a bit longer.
But I understand that people "sailing" on rivers or in the everglades need a motor propelled boat... no one is going to take that away, but probably more bio diesel will be available in future or ethanol.
So, you want to tell us you lived the last 50 years under a rock? And now random/. posters need to dig some links for you? Sorry, I learned this stuff 40 years ago in school, I'm to lazy to dig out links for people who are not working on their own education.
You asked your parent to show that no natural causes are involved.
I'm asking you, the person who claimed that the science was settled for numbers to back your claims. You can google yourself, that is called: getting an education.
When you are on a boat, make a radio call to a coastal radio station, and ask to get patched through via phone to your father in hospital: then obviously everyone on the same channel can hear you both. Nevertheless every one who "randomly catches" the conversation is supposed to be quiet about what he hears and "respect the privacy". Disclosing stuff you pick by that is forbidden by law. That is basically the first thing you learn when you make a radio license.
Usually you would use a duplex channel for that, so you usually only hear one person if you eavesdrop.
I have a hard time believing that intelligent life like us is common in the universe. I think it is extremely common. There is just no technology to discover them, except by accidentally looking at the right spot.
There should be evidence everywhere by now if intelligent life like us is easy and prevalent. The evidence is likely there, but as I said above: we only see it by accident, because there are to many stars to look at and most are for todays telescopes to far away.
A couple of conjectures that I am more likely to believe than intelligent life similar to us is everywhere:
Perhaps your definition of "similar" is extremely strict... I don'T expect exactly humans with our mentality and urge to search/discover and communicate.
Well, but that was not what the author claimed:D Unfortunately in my fridge are non of those foods. I basically only eat fish/meat with salad. And as I'm a Thai friend, the typical thai dishes around green papaya or soups.
Going from 15-20% annual colony loss to 30-40% annual colony loss just means that you have to pay a little more for pollination services. It also means that wild bees probably die out.
Ah, I thought I had seen the A!0 is flying about 33k feet hight, I was actually also checking wikipedia... but perhaps looked wrong or the german and english do not agree.
Regarding the Airships I'm a bit wondering, it is hard to find stuff. But I saw around age of 14 a movie happening during WWI and the enemy side had Airships with planes. I assumed that would be historically accurate. A huge deal was about the problem that the german Airships flew about 1000m higher and the enemy (I believe british) Airships and the planes could not really reach that altitude so they fired from like 500m below the Airship while in climbing flight.
Anyway, one link is a german Zeppelin, build for America after WWI as kind of reparation payment. LZ 126, later ZR-3 âzUSS Los Angelesâoe. It made capture and release experiments with biplanes at 3rd of June 1929.
Later they carried a glider and deployed it successfully. unfortunately the english article does not mention anything of this: https://en.wikipedia.org/wiki/...
So, now I have to search for that old movie, rofl.
Interesting topic, strange that the german wiki article has no references to back ground information either.
