. They are the binary compatibility of the standard Java platform. Java card virtual machine specification, 2.2.2 also defines a file format, which is standard for the binary compatibility of Java card platform: the form of software loading on the device in the CAP file format implemented Java card virtual machine. This javacard virtual machine specification (version 2.2.2) is the key to providing code portability. One way to understand what this
In the iOS app development process, we will use Xcode to package, generate. xcarchive package files, through the Xcode Organizer tool can manage, export the release file, I believe that iOS development for these processes are quite familiar with, here is not to repeat. The main want to say is, after packaging the dSYM file.Get the dSYM file by opening the Archives Management window first, such as:Once per archive, a record is generated to find the directory where the current record is located, s

If the append operation of slice and slice is not well understood, the use of slice as a reference type can result in loss of dataLet's start with an example:
Package Mainimport "FMT" type Dbitem struct {Id int16 Cnt int32}func combineitem (itemList []dbitem, Id int16, Cnt i Nt32) {Item: = Dbitem{id:int16 (Id), Cnt:int32 (Cnt)} itemList = Append (itemList, item) FMT. Printf ("Combineitem itemList addr[%p]
reference to an array. A slice consists of three parts: the pointer, the length, and the capacity. The built-in Len and CAP functions return the length and capacity of the slice, first of all, we'll look at how slice is created: create slice in two main ways: 1. Array-based creation. 2. Create directly 1. Base array creation: Arrvar: = [4]int{1, 2, 3,4}slicevar: = Arrvar[1:3] array Arrvar and slicevar the address is actually the same, that is, if you

Speed up Xcode compile link speed, Xcode compile slow solution
Recently in the development of a big project encountered a very headache problem, because the project code more, each time to compile the link 1 minutes, debugging time is very wasteful, so studied how to improve the speed of compiling links, here to share to everyone.
There are three main ways to increase the speed of compiling links:
1. Increase the number of threads used in Xcode compilation
Defaults Write Com.apple.Xcode pbxn

At the beginning, the understanding was wrong. Then constantly tangled in that, the Internet to see other people's blog, did not see the idea said very clearly, there is a translation of particularly funny.
Here is a careful word:
In a matrix of n rows m columns, each row has a dwarf statue and a candy, the purpose of which is to make every dwarf statue get candy. Now, let each line o
The Go slice (Slice) is an abstraction of the go array. Since the go array allows you to define a variable of type, you can accommodate several data items of the same data type, but it does not provide any built-in method to dynamically increase its size or get its own subarray. There is no such restriction on slicing. It provides many of the practical features required for arrays and is widely used in go programming.Defining slicesvar numbers []int/* not specified size */* numbers = = []int{0,0

A 64 m old USB flash drive is useless. If the USB flash drive is large enough, you can use more powerful mini Linux and winpe with more tools. This time we installed winpe + maxdosv6plux + dwarf dos5.3 + cdlinux0.4.9 + mclinux2.02 + bomberlinux3.7, and there should be more tools. There are many ideas: Method 1: You can first make a DOS boot disk, so that you can directly load various dos tools, and then use grub4dos to load winpe. Method 2: You can cr

through JNI. Because the data is written directly into the heap of memory, it is no longer possible to allocate memory in the JVM-controlled heap to store the data, and there is no operation in the heap of memory and the data copies of the outer heap. So when I am doing an I/O operation, I just need to pass this heap of memory address to the JNI I/O function.Directbytebuffer The source code of the creation and recovery of the outer heap memory heap outside memory allocation

There are three main ways to increase the speed of compiling links:
1. Increase the number of threads used in Xcode compilation
Copy Code code as follows:
Defaults Write Com.apple.Xcode pbxnumberofparallelbuildsubtasks 4
Xcode is compiled by default using the same threads as CPU cores, but because the IO operations in the compilation process tend to be more than CPU operations, the appropriate number of elevated threads can speed up the compilation to some extent.
