Geometry clipmap limits I like geometry clipmap very much, and even translated the famous paper of hoppe. Obviously, this is one of the classic examples of more and more graphic computing transfers from CPU to GPU. Unfortunately, there has never been a chance to implement it until some time ago, we had to write a terrain system and finally had a chance to try it. Before completing the terrain, everything was very good. Unfortunately, when texture was

Any UNIX: the limits set by ulimit or setrlimit. FreeBSD:Edit/boot/loader. conf, add the lineset kern.maxfiles=XXXXWhere XXXX is the desired system limit on file descriptors, and reboot. Thanks to an anonymous reader, who wrote in to say he 'd achieved far more than 10000 connections on FreeBSD 4.3, and says "FWIW: You can't actually tune the maximum number of connections in FreeBSD trivially, via sysctl... You have to do it in the/boot/loader.

OSPFThe Protocol is required by the customer and is in the following topology. Only the router R3 and R1 and R2 are allowed to establish a neighbor relationship, and the relationship between R1 and R2 is not allowed. The brief topology is as follows: OSPF limits the establishment of the FULL Neighbor Relationship-method 1 The advantage of changing the network type of OSPF is that LSA only transmits data on the relevant link and does not pass the data

JQuery limits the number of checkbox options This article mainly introduces JQuery's method of limiting the number of optional check boxes. It involves jQuery's skills related to checking the length of check boxes and modifying attributes. It is of great practical value. For more information, see This example describes how to limit the number of checkbox options in JQuery. Share it with you for your reference. The specific analysis is as follows: A sm

Introduction: If you read this book, you may have mastered the basics of iOS development. However, there are some minor features and practices that many developers are not familiar with, even for developers who have years of experience. In this chapter, you will learn some important development skills, but this is far from enough. You still need to accumulate more practices to make your code more powerful. /* This article is translated from Chapter 3 "You May Not Know" in iOS 7 Programming Pushi

Limits MongoDB memory usage Because MongoDB's memory is managed by the system's virtual memory, MongoDB does not interfere with memory management. This can simplify Mongo's work, but the memory usage of Mongo cannot be controlled at the same time.Is it really uncontrollable? You can useUlimitTo control the virtual address space of a user process.Ulimit controls the memory size of all processes. How can we control MongoDB? In fact, it can be changed. W
