一九四四年，雾，重庆。日本已停止了对重庆的轰炸，但“重庆大轰炸”的噩梦，留在人们心中的阴影仍然挥之不去。小公务员魏端本原在南京政府某部供职，抗战爆发后辗转撤退到重庆。路上遇到同是难的女孩子田佩芝。同是天涯沦落，发生了感情，结成患难夫妻。这已经是六七年前的事了。如今，他们已有了一对儿女。一家人挤住在一家杂货店的后屋。这是重庆彼时特有的“吊脚楼”--依山崖而建，从顶层出入，成年见不到一丝阳光。陈启这边在忙碌着。One last thing on this subject, The 7.62 mm traced armour-piercing firebombs fired by the 81-1 family, Although the name is a little long, But compared with ordinary munitions, The difference is still well understood: Tracing and burning are simple, Is to add two corresponding drugs, The armor piercing is to replace the steel core behind the bullet's brass back armor (also known as bullet head) with a harder tungsten alloy core with stronger penetration to hard targets. The latter is also the tail-stabilized shelling penetrator used on the third generation of modern main battle tanks (abbreviation: APFSDS) is one of the two main materials (the other is the notorious, highly radioactive depleted uranium penetrator core, The user country is mainly the United States, while China mainly uses tungsten alloy penetrators, Less pollution and better performance, The United States does not need to. First, the United States does not pass the standard of tungsten treatment technology. Far from the level of our country, Secondly, the United States is a tungsten-poor country. It also wants to fully use tungsten alloy bombs, But it can't be used, But as a nuclear Power, There is a lot of depleted uranium as nuclear waste, so depleted uranium is selected as a substitute. As for tungsten alloy and depleted uranium, after putting aside the key additional condition of radioactive pollution, the pure question of who is better in armour-piercing performance is not directly related to this article, so it will not be described in detail).The following list one by one.时间到了10年后……The Slowloris attack exploits a vulnerability in the web server (or an unreasonable parameter configuration) and directly causes a denial of service. Slowloris is an attack method proposed by famous Web security expert RSnake in 2009. Its principle is to send HTTP requests to the server at a very low speed. Since the Web Server has a certain upper limit on the number of concurrent connections, if these connections are maliciously occupied and not released, all connections of the Web Server will be occupied by malicious connections, thus new requests cannot be accepted, resulting in denial of service.
