So, you installed .NET Core RC2 , you followed the getting started tutorial and you got your “Hello World!” printed on your command prompt just by using the CLI. Then you went the next step and you tried to use Visual Studio Code and the C# extension to edit the application outside of Visual Studio. And finally you want to try and debug and set a breakpoint inside the application, but you encountered some pr

Exciting times lie ahead for .NET developers. During Build, Microsoft’s biggest developer event of the year, clear roadmaps were given on the future of .NET and C#. Microsoft is re-positioning .NET to be a platform that can be written anywhere and run anywhere, which is a departure from it’s long history of proprietary technologies.

Criminals have long employed the tactic of masking their true identity, from disguises to aliases to caller-id blocking. It should come as no surprise then, that criminals who conduct their nefarious activities on networks and computers should employ such techniques. IP spoofing is one of the most common forms of on-line camouflage. In IP spoofing, an attacker gains unauthorized access to a computer o

Oracle uses a Data Dictionary to store details of all the Tables, Columns etc.. (check out the associated Data Model). You will normally be interested only in your own Tables, which are provided by the 'USER' views, which are for the User who is currently logged in.
The System Administrator or DBA will usually be interested in the 'ALL' Views, which show data for all Users.

“梦想这东西和经典一样，永远不会因为时间而褪色，反而更显珍贵。”这是10月28日上线的网络短片《老男孩》在片尾打出的一行字幕，连日来，这部以草根、怀旧、青春、人生、爱情、友情等为基调的“电影”让众多网友直言“飙泪”、“泪流满面”，截至昨天下午，该片仅在某视频网的官方播放次数就已近1600万次。如果这是一部正式上线的电影，有一半的人买票（每张计半价25元），票房也有两个亿了……《老男孩》为什么红，它凭啥点中了观众的泪穴？

摘要：
Windows Communication Foundation (WCF) 中的可靠会话使用传输窗口保存客户端和服务上的消息。可配置属性 MaxTransferWindowSize 指示传输窗口可以保存多少条消息。在发送方，这指示在等待确认消息时传输窗口可以保存多少条消息，在接收方，则指示为服务缓冲多少条消息。选择合适的大小可影响使用网络的效率以及运行服务的最佳容量。
当编写一个允许从不同的客户端启用可靠会话通信的服务时，可能会有许多客户端同时建立与该服务的可靠会话。在这些情况下，服务的响应取决于 MaxPendingChannels 属性。当发送方创建到接收方的可靠会话通道时，发送方和接收方之间的握手将建立可靠会话。建立可靠会话之后，该通道会放入到挂起的通道队列中以供服务接受。此 MaxPendingChannels 属性指示有多少个通道可以处于此状态。

摘要：我每日坐5路地铁，从伽尼一站出来，都会看到一个没有头的人坐在路边，不时发出些古怪声响，引得途人侧目，他的面前，摆了只扁盒子，零散会有人丢几个硬币进去。
于这城里，这类表演是常见，无非是把肩下垫得很高，头缩下去，便看来效果了。尽管人皆心知肚明，但不免当下兴致，还有支付；或是孩子，不明就里，好奇大作，每每观析过多，父母不过意，扔几枚意思。
一日里，我一样经过这没有头的人，却有几个警察也过来，和他说了些什么。就在身旁，我不觉听了一下，大约是自这一日，上面下了新的时令，便是不得在街上行演了。
无头的人便释解起来，说是平日只是老实地坐在那里，并不妨碍行人；受来多少，任人自愿，从没纠缠；且是每日里收工，也把原地打扫一二，不留丝毫垃圾再去……。声音闷声闷气，从领子的洞里传出。

摘要：In my current project the MVP pattern is used in the supervising controller mode. The MVP pattern is an adaption of the old MVC pattern that incorporates that the capabilities of WinForms views have become smart enough to lift some of the burdens previously implemented in the controller. This applies to e.g. handling click events and data-binding; a presenter only injects the model into the view which

摘要：As discussed last time, delegates can produce memory leaks in our applications if not used carefully. Most often, this happens with events when we add a handler to an event, forget to remove it and the object on which the event is declared lives longer than the object that handles it. The following diagram illustrates the problem.

摘要：Why don't you partition your table if you have millions of rows and get complaints about the degradation of performance?
This is the question I asked my friend and I was amazed to find out he, along with many people, wasn't aware of this feature of SQL Server. This feature was first made available in SQL Server 2005, and today I will discuss what partitioning is.

We're finally seeing major new topics emerging into the early mainstream that are potential game-changers, while at the same time a few innovations that have been hovering in the margins of the industry are starting to break out in a big way.
