running shark. In this architecture, Spark replaces Hadoop as an ETL, while Shark replaces the commercial Bi/olap tool, taking on reports/dashboards and interactive/ad hoc queries, while interfacing with desktop bi tools such as tableau. The current spark cluster deployed on Yahoo has 112 nodes, 9.2TB of memory, and is considering adding SSDs.
Tim introduces the future of work. First of all, Pig/mapreduce will take the place entirely, with all the ET

However, you can enter the path in the text box on the keyboard. After running, you can generate a result to save the file and save the parameter value to save the file. But click the file button next to it, but you cannot set the path in both text boxes. This is also true for the official registration version. It seems to be a bug.Since 1stOptv1. 5 is like this, why not fix this bug.0068F47A mo

The specific input form can be determined based on my hobbies and habits, without sticking to a fixed pattern.8. questions about how to track programs: beginners often do not know how to track programs when learning to decrypt, how to find a place where the registration code is compared, and are overwhelmed when faced with a long pile of program code. Generally, software programs use a su

Call assert
Sometimes, the emergence of assert () macro is also useful: Usually this macro will leak the source file name, row number and condition.
The most useful information is included in the assert condition, from which we can infer the variable name or struct name. Another useful information is the file name. We can infer the type of code used. It is also possible to identify a famous open source library by fi
Don't optimize it! Let the compiler do it !, Optimize the Compiler
We often perform optimization on our own when writing code. In fact, most cases are unnecessary because the compiler is much smarter than you think!
The example below demonstrates that,
This is a kind of recursive writing. Many veterans will tell you that writing performance is low and loop should be used.
Int rfact (int x)
{
Int rval;
If (x
Return 1;
Rval = rfact (x-1 );
Return rval * x;
}
I don't think everyone has any object
$ indicates address reference, and not adding $ indicates value reference.Note: For local variables, You can reference them through the stack pointer.Intel: [_ booga]★Register indirect addressingAtt: (% eax)Intel: [eax]★Address Change AddressingAtt: _ variable (% eax)Intel: [eax _ variable]Att: _ array (, % eax, 4)Intel: [eax * 4 _ array]Att: _ array (% EBX, % eax, 8)Intel: [EBX eax * 8 _ array]2. Basic Embedded AssemblyThe basic embedded assembly is very simple, generally in the following form

Here, if jnz jumps, the entire process is over. Without a doubt, the call above jnz is the place for verification.
Double-click the call and we will track it in. There is nothing special, but such code is found
