First, obtain the output data of different corn in two minutes.
Because python's pandas package is used, you need to introduce the pandas package before reading data.

Different corn kernels are represented by a B. The first five rows of data are read below.

Reverse analysisLater, in the main function where we conducted a more in-depth sample analysis of the sample through IDA, the function dec_conf was first called to decrypt a large number of encrypted strings in the sample, as shown in.In the function dec_conf, the Encrypt_code function is actually called to decrypt, an
Sample Analysis instanceThe sample is an executable file disguised as a wmv media file,
Using the wmvfile icon, because Windows does not display the extended name of the known file, the actual name of the target sample is wr.wmv.exe.

Recently, an Heng engineer found a high-risk alarm in an APT threat analysis device deployed on a network, which contains many suspicious behaviors, this includes adding self-starting content, creating network socket connections, reading network files, collecting disk information, and obtaining the current
Recently took over a sample, the sample used a large number of XOR encryption, due to its own sample is not complete, can not run (ok my most porridge of the dynamic debugging is not, the sample is very interesting, there is time to do the big ticket analysis), this time had
Microsoft SQL Server Each version will have a corresponding sample project, from the 2000 FoodMart to 2005 after the Adventure Works, inside the design methods and specifications have a lot of things we deserve to learn. Not only do ordinary development, if you do BI development then you will find that this is a good guide, and Microsoft SQL Server installed in the Books Online tutorial is to use these sample
This article describes how to use XMLHTTP to obtain the web access header information and analyze the sample code of the web page. it has some reference value. let's take a look at it.

connection is made according to the key of two source entering mapper. Therefore, the data source is required to be ordered according to the key value. This connection is implemented on the map side. I used Keyvaluetextinputformat to handle the test and the default format was Key\tvalue, so I used the code above to reset the format. But if your file is not a key in the first place, you need to write your own fileinputformat. But it's obvious that the data source you're dealing with is going to

Attempts to write data to the memory that has been freed.
Cross-border operations (which are indeed the most common causes).
An attempt is made to write data to memory that has not been allocated.

I. Summary
The micro-credit public platform provides a simple example code for PHP, which we need to learn more about before further development.
Second, get the code

Idea: first set two subscripts, initialize them as the starting addresses of the two arrays respectively, and push forward in sequence. The advancing rule is to compare the numbers in two arrays. the subscript of the small array is pushed forward until the subscript of any array reaches the end of the array. if the same number is not touched yet, it indicates that the array does not have the same number.
PHP checks whether two ordered arrays have the same sa

2.3-xmn young belt space settings
Analyze the information of Def new generation. The current memory usage is 6464 K, Eden space 5760 K, from/to space: 704 K. its maximum space address is the same as the current address space location: 0x35580000, but the current memory usage is not completely completed, so we can guess that it sets the memory size of the young band.
Its maximum space address is 0x35580000-the minimum space address 0x34e80000 = 7 M. Therefore, its-xmn is 7 m.
