... Wait, it's all unreasonable.
In memory, the data and instructions are completely indistinguishable, and in the register, data and instructions are different, because different registers to save the various types of data address (CS save instruction Data segment address, DS save operation number of address ...) And the CPU is responsible for reading CS:IP determine the next instruction to store the address, read DS know will be processed
After reading the code at the Android Framework, I can find that the ubiquitous SP has a visual impact on me. What is this? At the beginning, I think this is basically used as a pointer, and I don't know its internal beauty. So I will learn and sum up the charm of the SP class here.
1 SP this product is a template class. Let's look at its structure.

About android's Unit (dp, sp) and androiddp
Android is a headache.
---------Android has the following units:
Common dip and sp, sometimes using px.
---------Two classes are introduced:
TypedValue: There are some methods related to unit conversion.
DisplayMetrics:
DisplayMetrics dm = new DisplayMetrics();getWindowManager().getDefaultDisplay().getMetrics(dm);DisplayMetrics has fields related to these unit

This algorithm can be used without noise and noise. In the case of no noise, if the matrix Phi satisfies the RIP condition with certain parameters, the SP algorithm can reconstruct the original signal accurately. When the measurement is not accurate, or

Display Unit: pixel, dip, and SP
Dip: Device Independent pixels (device independent pixel ). different devices have different display effects, which are related to the hardware of the device. We recommend that you use this function to support WVGA, hvga, and qvga without pixels.
Px: pixels (pixels). Different devices have the same display effect. Generally, we use hvga to represent 320x480 pixels, which is usually used.

1. There are two basic operations on the stack: Inbound and Outbound
In the stack, a new element is placed at the top of the stack. In the stack, an element is taken from the top of the stack;
2. The elements at the top of the stack always last in the stack and first out of the stack. This operation rule of the stack is called LIFO (last in first out) and then in first out.
3. The 8086cpu provides the inbound and outbound commands. The two most basic commands are push (inbound) and POP (outbou
Yesterday a friend came to me and asked if I could help find a programmer who couldn't get a job. I asked about their recruitment to go and treatment, in fact, is not low, but my friend still said to me, bad strokes.

Px: pixels (pixels). Different devices have the same display effect. Generally, we use hvga to represent 320x480 pixels, which is usually used.
If PX is used, it will be drawn with the actual pixel. For example, draw a horizontal line with a length of 4
Solution:
Manage IP:

Maintain IP:
spa:128.221.1.250 spb:128.221.1.251
Subnet Mask: 255.255.255.248
Note that due to subnet and IP restrictions, the client's IP can only be one of the following if you want to access the machine through the maintenance port:
128.221.1.248
