  1. Thanks! Anyway I am still using firefox.

    Another question is window 10 also keep your search records in search bar, and you have to delete them one by one, not delete all of them by one click.

    I am not surprise that The West is falling, it is just so dumb, example every website ask you do you accept "cookies" or not? lol, the rule must be made by those politicians know nothing about IT

    And those dumb webmasters use three frames, and give you 2 inches space to view their web pages.

     

     

  2. Why China, Vietnam, North Korea support Russia?

    China, Vietnam, North Korea  all called Russia as big brother.

    Mao called Satin as big boss.

    Chinese Called Stain as Kind father, "cifu".

    Chinese President Dr Sun Yat-sen said "Russia is our teacher."

    The West laughs at Russia lost a war to Japan, which Japan lost more soldiers. The West must forget the battle of Singapore, and the battle of Indonesia.

     

     

     

  3. have a look at the short paper attached.

    The number of the equal triangles should be 1+n/(n/2), if n=10, it is 55.

    Of you also count those up side down equal triangles, it should be n^2, if n = 10, it is 100.

    Then what is the author talking about?

    'Binary numbers' do not exist, neither do 'decimal numbers'. Numbers exist, but we can use different notations for them.

    Take the number 153, in decimal notation. This means:

     (1 x 100) + (5 x 10) + (3 x 1).

    With exponents you could write it as:

    (1 x 10²) + (5 x 10¹) + (3 x 10⁰).

    So the number is expressed as sums of multiples of powers of 10. So the base number is 10.

    In binary, 153 is written as 10011001, which means:

    (1 x 2⁷) + (0 x 2⁶) + (0 x 2⁵) +(1 x 2⁴) +(1 x 2³) + (0 x 2²) + (0 x 2¹) +(1 x 2⁰) 

    Which is in decimal:

    (1 x 128) + (0 x 64) + (0 x 32)+ (1 x 16) + (1 x 8 ) + (0 x 4)+ (0 x 2) + (1 x 1) = 153.

    Every number can be written in every base.

    Thanks.

  5. Do they have common sense?

    1) Mongolia conquered China.

    Mongols killed 50% of the Chinese population.

    "...According to the Chinese history not more than one hundredth part of the population survived, the countryside was covered with human bones, the cities left desolate..."

    —“The Mongol Conquest Of China And Its Consequences”, by George Tait Edwards.

    2)Mongols divided people into four classes, Chinese were the lowest.

    1. Mongols 2. Semu people  3. Northern Chinese 4. Southern Chinese

    ---Society Under Mongol Rule, www.encyclopedia.com

    3) Bayan, the Mongolian Grand Chancellor suggested killing  all Chinese with one of the most popular surnames.
    Bayan of the Merkid, Wikipedia

    4) Genghis Khan’s Yassa.

    “In cases of murder, one could ransom himself by paying fines which were: for a Mohammedan - 40 golden coins; and for a Chinese - one donkey (which was the cheapest).”

    5) Marco Polo  recorded that he met the Mongolian King,  Kublai Khan,  in Beijing.

    When Mongols took Beijing, Mongols killed  almost the entire population of  Beijing, and used the dead bodies to cook human oil.

    6) After Mongols conquered China, China became a part of Mongol Empire.  The Chinese King was ordered to commit suicide.

    Emperor Gong of Song, Wikipedia

    7) Marco Polo  recorded that Mongols  called China as Manzi(barbarians).

    As European and Arab travelers started reaching the Mongol Empire, …. Southern China, ruled by the Song dynasty (By the Chnese King), was (called) Mangi, Manzi, Chin, or Sin. The word Manzi  or Mangi is a derogatory term in Chinese meaning "barbarians of the south" but it was adopted by the Mongols to describe the people and country of Southern China.

    The name for South China commonly used on Western medieval maps was Mangi, a term still used in maps in the 16th century.

    Cathay, Wikipedia

    9) At the tome of Marco Polo, China was a part of Mongol Empire.

    Please have a look at the map.

  6. I think

    1) If there is one transaction, the first one.

    There are one database and one record,

    if there are x transactions,

    There are x databases and x records. in each database, they have the same records.

     

    2) The password is 32 characters long.

    If 0/0= a then 0 X a= 0 is also "well defined".

    a/0, for non-zero a, is "undefined"  because if we set a/0= b then a= bX0= 0 which is not true.

    0/0 is not defined because if we set 0/0= b then 0= bX0 for any b.

     

    Many people say 0/0 is "undetermined" rather than "undefined".  But there is no good reason to set it equal to 0.

    I still do NOT think so.

    1) 0/0 =0, it is like 1/1=1, there is no such thing, "if we set 0/0= b then 0= bX0 for any b.".

    0/0 only has one value, which is 0.

    1/1 has only one value, which is 1.

    2) It is easy to prove that X/0, X!=0 is NOT defined.

    since if X/0 = Y,  then 0 X Y = X, and X!=0 are NOT possible.
