  1. We need to have people off planet on Moon is Stepping Stone, Not Alternative To Mars, NASA Chief Says (scientificamerican.com) · · Score: 1

    You are making some wrong assumptions here. The goal is not to save the human race but the civilisation and Earth itself. Even in the worst case scenarios of asteroid strikes or supervulcano eruption the human race will survive, the human civilization or the earth ecosystem not.
    Technologically we can do any time a self-sustainable earth “colony” anywhere on Earth but there is no need for it. Nobody will invest in a self-sustained outpost in Artic or desert when is much cheaper just to haul supplies from earth.
    Having a permanent presence outside the gravity well is having both short and long term benefits.
    Short time:
    - Having a fuel resupply station in space will decrease the costs of longer range missions and at the same time making impossible missions possible.
    - Have a platform from where you are not only observing the space outside the atmosphere and electromagnetic interference but also a place from where you can launch “strike” missions against dangerous asteroids.
    - A place from where you can launch missions for controlling climate via a solar shade against global warming for example
    Medium time:
    - Start making a self-sustainable habitat step by step by harvesting resources from asteroids and make an artificial biome at the same time
    - Make an industrial base in zero-g which could manufacture some materials which will be more expensive in earth gravity or even impossible
    - Get rid of nuclear waste or even make experiments which are too dangerous on earth like a damned big nuclear weapon able to pulverise an asteroid
    Long time:
    - Create a network of habitats which will help us colonize space and planets.
    - Whatever will make us to not keep all the eggs in the same basket.
    At this moment I’m against focusing on mission to Mars because even if it is technically possible now if you throw a lot of money, it will be nothing more than a gimmick and a onetime shot like the moon landing was. It was an engineering marvel but was written off because of lack of long time vision (politically).

  2. Re:So where's the "Honda crashes into bus!" storie on Days After A Fiery Crash, a Tesla's Battery Keeps Reigniting (mercurynews.com) · · Score: 1

    Except the subject in those articles is the driver/victim and not the brand of the car. "4-year-old dies in fall from moving pickup", "Pair 'flee' crash after car hits bus in Rowley Regis", "Sandwich woman crashes car ..." where any news involving a Tesla car is "Tesla craches ...". Even taking into consideration the "autopilot" function, long before you know the autopilot was involved or not is the Tesla car doing the stuff.

  3. Re: because they're subjected to rigorous inspecti on Trump Withdraws US From Iran Nuclear Deal (nytimes.com) · · Score: 1

    Yes because cleaning in 30 days all traces of radioactive materials with half-life of billions of years it's an easy task. And doing it so with all satellite surveilance.

    If iranians know how to do this we should lift all the sanctions at once and pay them good money for the technology. It will be really usefull in cleaning up the nuclear mess in some places.

  4. The truth is in the middle on Bloomberg Starts Tracking Tesla Model 3 Production (bloomberg.com) · · Score: 1

    Your estimate is wrong. 7,202,335,148,562,342,439,363,104,735,232 units per month will be one month after 7.5 years. The correct number is 3601167574281171219681552367616 (feel free to insert the commas).

    Considering the GP estimate of 1025 cars a week will result 53446 cars/year or 53592 (for a leap year) which translates into a monthly production rate between 4454 and 4466.

    Considering the truth is in the middle I would calculate the monthly production of tesla to be between 1800583787140585609840776181581 and 1800583787140585609840776181575 cars/month.

    Now back to my MBA course.

  5. Strawman argument on Pro-Gun Russian Bots Flood Twitter After Parkland Shooting (wired.com) · · Score: 1

    So policies directed at mass shootings tend to be ineffective at actually reducing gun deaths. Because of the meticulous planning, mass shooters are difficult to detect. Because of their mental illnesses, they are difficult to deter. This is precisely where gun control will be least effective. The world's worst mass shooting was in Norway, not America.

    How many mass shooting are in Europe and how many in US? (according to definition of 4 or more victims). USA have already 30 and it's just the beginning of the year. I will not go over your arguments because ALL of them are false and based on false dichotomies premeditate/impulsive, rifles/guns, crazy/stupid, not criminal/criminal.

    Gun control works. And please do not bring the subject of Switzerland which is sooo different than US including gun legislation.

  6. Not really true on 'How We Made Starship Troopers' (theguardian.com) · · Score: 1

    Hollywood is pathologically incapable of making a movie that conveys a conservative message

    About free market, low taxes, low government, industry deregulation, real freedom and right of having guns you have the "Mad Max" series.

    And about the values of the traditional family in shaping the future you have "A boy and his dog".

    "150 spots gone" This is what I remarked also. Why not arange them as roofs to provide shade for the cars in the parking lot? This will make the cars cooler instead of getting hot in the sun and reduce the need for airco.

  8. Exactly. Russia doesn't have the NSA, it doesn't have a direct point of access to the world's biggest Internet companies...Russia can't do 10% of what the US does in the "cyber sphere".

    No she haves KGB aka FSB. Citation needed for those 10%.

    Any cyber treaty would severely limit what the US can do NOW, while only theoretically limiting what other countries MIGHT do.

    Bullshit.

  10. I did not find statics for week consumption but I tried. Maybe my googlefu is not so strong or data is not easy accessible.
    Despite not being in the industry I tried my best to aggregate data for making sense of the news.
    Looking back at my first post I still consider my estimates very optimistic regarding the advance of renewable energies.

  11. During the we you have mainly residential consumption and during the week you add industrial consumption. This is the reason for my assumption.
    EV's will increase the demand on electrical grid. I do not know if a modern coal plant will be more green than a gas engine.
    EV's charged at night? Only wind power?

  12. 30% of residential consumption energy I found documents for it. 20% for Germany was just a ballpark number as I did not found statistics for it.
    On the other side I did not consider that 85% was the peak number in the weekend but just considering it as an average.
    My estimates where too conservative if anything ignoring the storage of energy of which nobody speaks about.
    If you are at it just consider switch to electric vehicles which will increase demand further.
    Maybe I'm wrong but I see "this green way" being more polluting than alternative solutions (nuclear). Germany dumps nuclear energy in favor of coal.

  13. Not bad but far from being good on Germany Sets New National Record With 85 Percent of Its Electricity Sourced From Renewables (digitaltrends.com) · · Score: 3, Informative

    So in the weekend on the perfect day when solar and wind are at max we are covering 85% of residential consumption.
    In the European Union household electric energy consumption is about 30% rest being the industry and services. Considering Germany industrial sector it will be safe to say the domestic energy consumption will be around 20% of total electric energy consumption.

    So in a perfect weekend Germany was able to provide less than one fifth of electricity consumption during the week.

    To cover the industry renewable capacity will need to increase at least five times to work in perfect conditions. Considering the fact the best spots for solar and wind have been already used (unless they were stupid to chose the worst locations in the first place) we are going to start the law of diminished returns.

    Just adding that EU goal of being totally green and use only renewable resources is made partially by relocating production to China with their record of being "clean" I see a long way to go to reduce CO2.
     

  14. How can they patent it? on A Caterpillar May Lead To a 'Plastic Pollution' Solution (bbc.com) · · Score: 2

    On one side they do not know how it works.

    They think microbes in the caterpillar - as well as the insect itself - might play a role in breaking down plastic.
    If the chemical process can be identified, it could lead to a solution to managing plastic waste in the environment.

    On the other side they patent it

    Dr Bombelli and colleague Federica Bertocchini of the Spanish National Research Council have patented the discovery.

    Bariatric surgery proves the reverse. Just reducing the volume of stomach makes the body filling full faster. And it's effective.

  23. Re:Odd thoughts: on Microsoft To Support SSH In Windows and Contribute To OpenSSH · · Score: 1

    One thing nice about Powershell is that you can truncate options as long as they're not abmiguous. So you can make -Recursive be -Rec, or even -R, as long as there's not also a -Recreate or -Recover options. That seems to be a nice middle-ground.

    Sounds good and cool but what is happening if "Recursive" is the only option now and tomorrow not (adding a new option/functionality Recover)? Your script which was running fine before will create an ambigous command and stop working in the new version of the shell.

  24. Re:Verbosity is easy? on The Reason For Java's Staying Power: It's Easy To Read · · Score: 3, Informative

    A Stream is not a String. A Stream is a pipe which can serve you bytes as soon as some of them available.
    If the InputStream.toString() will give you the full content of the stream you will have some very nasty errors. Eg. A beginner wants to read a file using a stream and is doing a toString() suddenly all the file will be loaded into memory into a big String eating all the memory. Another beginner listens to a tcp port using a stream does a toString() and suddenly the thread hangs until the client closes the channel. Plus you need a reader on top of the stream to have proper String encoding. Stream is for binary Reader is for strings.

    “I find it extremely annoying to have to cast things into the right object type” This is by design, Java is strongly typed. If you find yourself casting too much then is something wrong with your code style or the library that you are using.

    Multiple inheritance is a broad topic. It's needed, but how much and how easy you can avoid it's a matter of balance. Interfaces do it well in Java and C#. You do have some duplicate code but you avoid ambigous calls to methods.

    Operator overloading is a can of worms. Perfect good tutorial are showing complex numbers (and one of the few places you need). Worst gotchas are in c++ overloading operators plus impicit casting. Eg.

    list array;
    list += 2;

    Will add 2 to the list or add an empty list with 2 guaranted spaces to the array? Last time I checked (loong time ago) it was the last. Clean code with a lot of gotchas.
