创建linux ios镜像时提示下载ldlinux.sys和ldlinux.bss

ldlinux.sys和ldlinux.bss 下载链接

第一种方法:首先从官网下载最新的Rufus软件,官方地址:http://rufus.ie/

日期目录以双击rufus-xxx.exe文件后,rufus_filessyslinux-6.04 自动生成的文件夹为准。

根据下面路径新建指定文件夹:C:Rufus-xxxrufus_filessyslinux-6.0420200826(日期灵活变通)
下载压缩包,解压两个文件到20200826文件夹里(跟上面对应)

返回Rufus-xxx目录,双击rufusxxx.exe,再次创建linux ios启动盘即可OK。

第二种懒人方法:

直接下载压缩包,解压根目录,运行里面的rufus-XXX.exe即可。链接: https://pan.baidu.com/s/116_ifQTboHJ0reXwa7NeyA 提取码: jvdu

The People's Liberation Army launched two missiles into the South China Sea yesterday (26th) morning, one of which is the Dongfeng 21D aircraft carrier killer anti-ship missile. This move is to warn the United States.

On Tuesday, the U.S. U-2 high-altitude reconnaissance plane once broke into the no-fly zone for live-fire exercises in the northern theater of the People's Liberation Army, prompting the Chinese Ministry of Defense to protest, saying that the United States was provoking. Yesterday the People's Liberation Army conducted a test-fire of anti-ship ballistic missiles in the South China Sea, and the US military dispatched reconnaissance planes to conduct reconnaissance.

The report pointed out that the PLA launched Dongfeng 26B and Dongfeng 21D missiles, intended to warn the United States. The two missiles were launched from Qinghai and Zhejiang, respectively, towards the sea between Hainan Province and the Paracel Islands.

Previously, the Hainan Maritime Safety Administration had announced that it would conduct military training in the waters southeast of Hainan Island from the 24th to the 29th, and both missiles fell into the exercise prohibited zone.

敲黑板划重点

-128 到 127的两个 Integer 对象,怎么比较都一样,超出此范围的的只有 equals() 时才相等。
Java自动装箱是对于从 -128 到 127 之间的信息值,它们在被装箱为对象数据后会在内存中被重用,也就是对于相同的值,返回的是同一个对象(这一点,类似 String 类)。
直接与数值比较时(即 a==300000 这样),大概是拆箱比较了,就跟 int 的比较一样了,所以该相等还是相等的。

所以, 就会出现如下情况

 Integer a = 128;  
 Integer b = 128;  
 System.out.println(a==b);   //false
 System.out.println(a.equals(b));  //true

比较Integer大小可以使用,Integer.intValue进行拆箱,比较的就是int值。

Science and Technology Daily, Beijing, August 25 (Intern Gao Xingjian) According to a recent report on the "Nature" website, through in vivo experiments on small laboratory animals, two groups of researchers in the United States and China have discovered that the infusion of candidate new crown vaccines in the nasal cavity can start To achieve the immune effect, and may be more effective than traditional injection vaccines, it is expected that after the vaccine is put into use, it can be provided to the public more efficiently, and its social benefits cannot be underestimated.

In order to implement the nasal vaccination experiment, a team from the University of Washington School of Medicine designed a candidate vaccine that can encode the spike protein of the new coronavirus. It is through this spike protein that the new coronavirus completes the infection process by binding to the host cell. The researchers injected the vaccine into mice that have the human receptor corresponding to the protein after bioengineering.

According to records and observations, after the injection of the vaccine, no infectious virus was found in the lungs of the mice exposed to the new coronavirus, but a small amount of viral RNA was indeed detected. In contrast, no viral RNA was detected in mice vaccinated nasally, combined with other evidence that nasal vaccination can achieve complete immunity.

At the same time, the research team of the First Affiliated Hospital of Guangzhou Medical University used another vaccine that encodes the spike protein of the new coronavirus to conduct experiments on rhesus monkeys. The researchers found that nasal vaccination is the same as traditional injection. Play the effect of preventing virus infection. At the end of the experiment, the trachea and bronchus of rhesus monkeys who received different doses of injection or nasal drops were sampled to detect viral nucleic acid at 9 sites, and the results were all negative. In contrast, monkeys that have not been vaccinated have detected high levels of virus in different locations.

The researchers said that the discovery of nasal vaccination methods can enable people to instill vaccines by themselves, which makes vaccination more convenient and easy. At the same time, the method of nasal immunization is expected to reduce the potential immune problems caused by the adenovirus vector itself and achieve better The immune effect.
