Prepare the environment:
Because no 1000 m network machine is available, connect the two laptops with a direct connection to form a M Ethernet network. Yes, it's a straight-through line. Now, the network card can adapt to cross-line and direct-through lines, and the speed is not affected. After a while, the machine has no problem.

Support for accessing or configuring MONGODB through the Bson statement. Hubbledotnet provides two stored procedures sp_excutesql and Sp_querysql to allow users to manipulate MongoDB directly with Bson via Hubble
Support for incomplete documents. Mongodb is a document database, and it does not enforce that the fields of each record are fixed as a relational database, and that each record may have different fields. Hubbledotnet supports this design, which is handled as nul

And in reality, is to spend six hundred or seven hundred to buy a i3, or 1000 buy a i5, the specific situation of the specific analysis, there is no fixed answer.4) If it is local tyrants, just a ' cool ' word.

Here is an example of pruning. For example, during the generation process, the listed 3_item set includes {I1, I2, I3}, {I1, I3, I5 }, {I2, I3, I4}, {I2, I3, I5}, {I2, I4, I5}, but because of {I3, I4} and {I4, i5} does not appear in the middle, so {I

(Tip: Why do you compress CK?) Because the actual situation of transaction records are often stored on the external storage, such as databases or other formats of the file, in each calculation of the candidate count will need to compare the candidate with all transactions, it is known that access to the external memory is often relatively low efficiency, so Apriori joined the so-called pruning step, The candid

, these five packaging classes create cache data of the corresponding type of value [-128,127], but new objects will still be created beyond this range. The packaging classes Float and Double of the two floating point number types do not implement the constant pool technology.1) Integer and constant pool
Integer i1 = 40;Integer i2 = 40;Integer i3 = 0;Integer i4 = new Integer(40);Integer i5 = new Integer(40);Integer i6 = new Integer(0);System.out.print
scenario
(1 ). integeri1 = 40; Because Integer is the packaging class of the basic data type int, it is an object, so Java will execute the automatic packing operation during compilation to directly encapsulate the code into Integeri1 = Integer. valueOf (40) to use objects in the constant pool
(2). Integeri1 = newInteger (40); in this case, a new object is created.
Integer i1 = 40;Integer i2 = new Integer(40); System.out.println(i1 == i2);//false
In this case, new Integer does not automatically
