Problem ScenarioLong time not to write blog, recently moved, re-run the network, found the same router, to the ping here is basically no single digit, so try direct broadband dial, ping value is basically 3MS, but after the connection router has an exception, that is not the operator's problem, In the middle of trying out the various methods on the network does not work, so began the following processingNote:The personal network knowledge is too poor, this blog left to use the reserve note1, lan

from the idea of Dijkstra in 1978. We believe that this algorithm can adapt to the needs of modern hardware and low-latency software systems because of the maximum cost-level garbage collector. In a tri-color collector, each object has one of three colors (white, gray, and black). We look at the objects in a connected graph. At the beginning of each GC, all objects are white. The GC accesses those root node objects, including global objects, objects

, although the accessed Website Cannot know your IP address, you can still know that you are using the proxy. Of course, some webpages that can detect IP addresses can still find your IP address.Transparent proxy means that the client does not need to know the existence of a proxy server, but it still transmits the real IP address. Do not use this if you want to hide it.As we all know, the proxy IP address is the foundation of crawler, and the high-availability IP proxy is the top priority of cr

Native javascript implements image scrolling, delayed loading, and javascript latency Effect: loading starts only when the image appears in the visible area in the drop-down scroll bar. Ideas: (1) img label: place the real image address in the property set by yourself, such as lazy-src. (2) obtain the height of the img from the page (offset (). top in JQ). The native is: Img. getBoundingClientRect (). top + document. body. scrollTop | document.doc ume

For front-end engineers, Apicloud undoubtedly provides us with a good platform, there are a variety of modules for us to use, but in the actual project, a lot of code, or we need to use HTML CSS JS to achieve. However, the mobile page has a 300 millisecond delay for the Click event, causing most users to feel that the HTML-based Web application interface on the mobile device is slow to respond.An easy-to-use JS Library is recommended here to eliminate the delay caused by the Click event in the i

In a mobile browser, when you click on a button's click event, it will wait approximately 300ms of time. This is because the browser is waiting to see if you are really doing a double-click.Sample Demo:For more information, please refer to the Fastclick official GitHub project addressHttps://github.com/ftlabs/fastclickFastclick.js File Download linkHttps://raw.githubusercontent.com/ftlabs/fastclick/master/lib/fastclick.jsFastclick Eliminate Mobile-click event

In Cap theory, the database is in (C) onsistency, (A) vailability and (P) artition-tolerance Three can only meet two. For example, MongoDB has better high availability, distributed. The inevitable sacrifice. [Consistency] Some time ago the development group's reflection said a record after inserting, again inquires, did not inqui
