Batch mining
&# 8205;&# 8205;&# 8205;&# 8205;&# 8205; Now the price of bitcoin is very high, so many people want to dig bitcoin. To dig for bitcoin, you first need to understand what bitcoin mining is. Bitcoin mining is the process of packing data and generating blocks. According to the computing power you contribute, you can get the rewards corresponding to the packed blocks

unknowingly, it came to 2014, with several Avalon generation USB mining machines in hand. You're right. It's not a roasted cat USB miner or any other chip. It's a USB miner of Avalon generation, with a single computing power of about 300m. Of course, the USB mining machine with more than 300 m computing power is of little practical value. It's just a souvenir for everyone<
first, the appearance
first, let's look at the appearance. The workmanship is regular, not exquisite, but slightly rough:
Second, the required software
let's start running cgminer to see how to use it in practice. Before starting work, you need to download three softwares:
1. Cgminer. Anyway, the latest version of 3.9.0 is also available for testing, http://ck.kolivas.org/apps/cgminer/
2. Zadig. This software is needed to replace the driver later. Download it from the same directory as cgminer
3. USB driver of mining machine, http://www.silabs.com/procts/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
3. Install and run
after downloading the above software, start to install and run
1. Insert the USB miner first, and you will be prompted to find the new hardware, and then complete the driver installation according to the prompts
2. After the driver is installed, you can see the new things in the device manager
3. Run Zadig, first click options -- list all devices, then drop down to select port, and replace the driver silabser (v6.6.1.0) with the driver WinUsb (v6.1.7600.16385) recognized by cgminer. After this step is completed, it is recommended to restart the computer
4. Create a new batch file in the cgminer directory, The following command: cgminer - O pool address - U miner name - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: number of mining machines
there are six USB mining machine fish pools, for example: cgminer - O stratum+ tcp://stratum.f2pool.com : 3333 - U AAAA. 2 - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: 6
since cgminer3.2.0, The method of supporting USB mining machine is modified, which does not need to add the - S - com parameter
5, run batch processing, and start to display mining data, about 300m, which is basically normal.
search for bitcoin data blocks, first understand the concepts of blocks and mining, and then talk about ASIC
1. Network hi
Network hi supports up to 1000 friends, which is a very large number. No one should say "friends are full" any more. Experience the video and voice chat function of hi
2. Alibaba Wangwang
is a new brand integrating Taobao Wangwang and Alibaba Tradelink. Taobao and Alibaba are free online business communication software tailored for businessmen
3, wechat
in Android wechat version 5.1, if users install Tencent mobile Manager Version 4.6, they can enable the mobile security protection function on wechat, which can make wechat and other mobile applications avoid the intrusion of malware and viruses, rece the risk of number theft, and improve the privacy security
{rrrrrrr}
4. Eason is the latest and most popular mobile chat software at present, which not only supports sending high-definition voice, text and pictures, but also has free SMS, telephone messages and rich and interesting expressions
Shangxun BB, also known as Shangxun baby, Shangxun baby and Shangxun Beibei, is a powerful web communication software that Chongqing Zhongshang science and technology group spent three and a half years and invested millions to develop. It is safe, reliable and stable Sina UC also provides chat rooms, online games, alumni records, online karaoke and other entertainment services. UC instant messaging tool has about 80 million registered users, and the maximum number of online users is about 200000Main differences between CPU and GPU:
1. CPU is the central processing unit of computer
GPU is the graphics processor of computer CPU is a very large-scale integrated circuit, which includes Alu arithmetic logic unit, cache memory and bus CPU is the core of a computer's control and operation, its main function is to interpret the instructions issued by the computer and process the big data in the computer software GPU is the abbreviation of image processor. It is a kind of microprocessor which is specially used for PC or embedded device to perform image operation The work of GPU is similar to that of CPU mentioned above, but not entirely. It is designed to perform complex mathematical and geometric calculations. This game has high requirements in this respect, so many game players also have deep feelings for GPU
so CPU and GPU are two completely different things, they just sound the same
extended data:
CPU and GPU are different in design because they are used to deal with different tasks at first, and some tasks are similar to the problems that GPU is used to solve at first, so we use GPU to calculate. The operation speed of GPU depends on how many pupils are employed, and the operation speed of CPU depends on how powerful professors are employed, The professor's ability to deal with complex tasks is very good, but for less complex tasks, it still can't hold many people
of course, today's GPU can also do some slightly complicated work, which is equivalent to upgrading to the level of junior high school students and senior high school students, but it still needs CPU to feed data to the mouth before it can start to work, which is still managed by CPU
attention
this is a pure novice tutorial
let's start from the beginning:
batch bat document creation, so you need to use batch command, which is a bat document
create a new TXT document directly, and then change the suffix to. Search some batch commands on the network. It feels like an advanced tutorial, because you need to use a batch command to batch add domain users in Windows Server. Where is the bat file, and where is its running path

2004 and as version 2.0 in flash
8, and AS3.0 in flash
9
CS3. You can see that as2.0 is to maintain software compatibility, In other words, flash
9 can normally open and run the old version of flash files.
the difference between as1.0 and as2.0 is not very big, because the programming commands in 1.0 can be used normally in 2.0, and 2.0 can be understood as an extension of as1.0 function. Although it introces a new programming idea (OOP), it is not perfect. Therefore, AS3.0 was launched later, and this version has fundamental changes, In addition to the functional expansion, the language architecture has also been greatly adjusted. Many AS1 and as2 commands can't be used in AS3.
I personally like AS3
flash
javescript
this thing is simply used to control the Flash software itself. It is similar to batch processing. The general personnel engaged in flash seldom contact with it. After you have enough understanding of flash and as, I will tell you in detail:)
I often use flash to develop games, so I have accumulated a lot of knowledge about flash ~ ha ha
