这是一个特殊年代的故事。这是一段人类改造自然利用自然的传奇。这是一部歌颂中国北部高原荒漠塞罕坝上老一代造林人奉献青春和生命的英雄史诗。上世纪六十年代初，为减少京津冀地区的风沙危害，国家指定由林业部和河北省在承德境内高原荒漠塞罕坝上建立机械林场，抵御浑善达克和科尔沁沙地南侵。以主人公冯程、覃雪梅等为代表的第一代造林人——来自全国18个省市的林业大中专毕业生与林业干部职工为骨干的369人开荒队伍，带领当地干部群众拉开了与自然抗争的序幕。岂料，因造林立地条件恶劣机械造林失败，转为人工造林。他们在平均海拔1500米、最低气温超过零下43度的环境下，在长达半个世纪的时光里，战严寒、斗酷暑、抛青春、洒热血，营造起“世界上最大的人工林海”，筑牢京津冀绿色生态屏障，拱卫京津冀蓝天，在荒凉的塞罕坝上，冯程和他的伙伴们同进退，共患难，也收获了友谊和爱情，谱写了壮丽的人生诗篇。

Javascript neither supports abstract classes nor has the concept of interfaces. Therefore, be very careful when using the state mode. If you forget to implement the buttonWasPressed method for a state subclass when writing a state subclass, an exception will be thrown when the state switches. Because Context always delegates requests to the buttonWasPressed method of the state object. Therefore, let the abstract method of the abstract parent class throw an exception directly, which will be found at least during the program run.

B) Use the tool BlueJ. The biggest advantage of BlueJ is that it provides a simple class diagram. As I did in the concise design pattern Java, I seldom draw class diagrams specifically, but take screenshots in BlueJ. When students write demonstration programs on the computer, they often look at his class diagram first to judge whether his program is correct or not, and then look at the source code when necessary.

At present, under the guidance of the Network Security Administration Bureau of the Ministry of Industry and Information Technology, CNCERT organizes provincial sub-centers, operators, security enterprises, cloud service providers, etc. to continuously carry out DDoS attack resource management, requiring all units to timely notify and process servers, computer hosts and intelligent devices found to be used for reflection attacks, and requiring operators to strengthen the fine management of false source address traffic. In addition, it is recommended that users and relevant users improve their network security awareness and security protection capabilities, update and upgrade firmware or service programs in a timely manner, repair vulnerabilities, and standardize security configuration. For servers, computer hosts and smart devices that do not need to provide public Internet services, it is recommended to directly shut down DNS, SSDP, NTP, SNMP, Chargen, Memcached and other services, or block external IP access to these service ports on firewalls or network entrances and exits. For those who need to provide services to designated IP, access control policies such as firewalls can be configured to allow authorized IP access and prohibit other IP access. In addition, some services such as Memcached can also prevent reflection attacks by changing the default service port or changing the transmission protocol type to TCP. For those who need to provide public Internet services, according to the characteristics of reflection attacks, the message traffic of specific reflection attack instructions can be monitored, identified and filtered, and the forged source IP address of reflection attacks can be monitored, identified, limited in speed, limited in flow and intercepted.
