  • [HOWTO:; Linux; Linux] Getting Started with SE Linux HOWTO: the new SE Linux #
    Getting Started with SE Linux HOWTO: the new SE LinuxFaye Coker faye@lurking-grue.org Last update: 06 December 2003 This document has been revised for the new SE Linux. The old 'Getting Started with SE Linux HOWTO' will remain in place as a legacy document, but it is highly recommened that all new installs of SE Linux use the new SE Linux. The new SE Linux runs on 2.6.x kernels and has also been backported for 2.4.x. This document is largely a duplicate of that for the old SE Linux, with modifications made where necessary. This document is a general introduction to NSA Security Enhanced Linux. It is mainly focused on Debian and as such command examples given for package management are largely Debian based. This document is tailored towards people wanting to get started with SE Linux so there's no confusing advanced stuff here. See the Resources section for links to other SE Linux material.
  • [Debian; HOWto; Oracle] Oracle10g on Debian Linux HOWTO | linux.inet.hr #
    Is running Oracle10g on Debian Linux possible? Oh yes, definitely! And it runs great, really. It's even easier to install than the older versions of Oracle as there are no problems with incompatible libc library & other bugs. You need to make just two simple preparations before you can enjoy your new development database.Important note: I tested this only on the Debian unstable distribution and only with the 2.6 kernel, as that's what I'm running. I believe that most of you that are running Debian unstable are also running the newest stable kernel, so that shouldn't be a problem, right? Let's go step by step...

  • [Windows Server 2003&Windows Vista] WindowsDevCenter.com -- Best Windows Admin Downloads #
    More than 9,000 tools, templates, white papers, and other items are currently available from the Microsoft Download Center, and all of them are free. What's a busy admin to do? To help you sort the wheat from the chaff, I've compiled the following list below of must-have downloads every Windows admin should have from the Download Center. To make it easier for you, I've categorized my selections into two groups -- product downloads, and documentation and templates -- with the focus on general tools and documentation for administering Windows Server 2003-based networks.

Attack

  • [Attack] Category:Attack - OWASP #
    Note: many of the items marked vulnerabilities from CLASP and other places are really attacks. Some of the more obvious are: Command injection Log injection Resource exhaustion SQL injection Reflection injection Reflection attack in an auth protocol

Advanced Linux and Unix Programming

  • [Advanced; Linux; Programming] Advanced Linux Programming | linux.inet.hr #
    The book written by Mark Mitchell, Jeffrey Oldham and Alex Samuel (CodeSourcery LLC), originally published by New Riders Publishing.If you're a developer already experienced with programming for the GNU/Linux system, are experienced with another UNIX-like system and are interested in developing GNU/Linux software, or want to make the transition from a non-UNIX environment and are already familiar with the general principles of writing good software, this book is for you.Advanced Linux Programming is published under the Open Publication License, Version 1, no options exercised.
  • [Secure; Unix; Programming; Linux] Secure Programming for Linux and Unix HOWTO -- Information on Creating Secure Software #
    Secure Programming for Linux and Unix HOWTO -- Creating Secure Software This is the main web site for my free book, the Secure Programming for Linux and Unix HOWTO. This book provides a set of design and implementation guidelines for writing secure programs for Linux and Unix systems. Such programs include application programs used as viewers of remote data, web applications (including CGI scripts), network servers, and setuid/setgid programs. This document includes specific guidance for a number of languages, including C, C , Java, Perl, Python, and Ada95. I give this book away in the hope that future software developers won't repeat past mistakes, resulting in more secure systems.

CDN

  • [web2.0; web; cdn] 系统管理员社区 - CDN 内容分发网络技术 #
    高速缓存服务器(Cache Server)是软硬件高度集成的专业功能服务器,主要做高速缓存加速服务,一般部署在网络边缘。根据加速对象不同,分为客户端加速和服务器加速,客户端加速Cache部署在网络出口处,把常访问的内容缓存在本地,提高响应速度和节约带宽;服务器加速,Cache部署在服务器前端,作为Web服务器的前置机,提高Web服务器的性能,加速访问速度。如果多台Cache加速服务器且分布在不同地域,需要通过有效地机制管理Cache网络,引导用户就近访问,全局负载均衡流量,这就是CDN内容传输网络的基本思想

MPU6050是一款广泛应用在无人机、机器人和运动设备中的六轴姿态传感器,它集成了三轴陀螺仪和三轴加速度计。这款传感器能够实时监测并提供设备的角速度和线性加速度数据,对于理解物体的动态运动状态至关重要。在Arduino平台上,通过特定的库文件可以方便地与MPU6050进行通信,获取并解析传感器数据。 `MPU6050.cpp`和`MPU6050.h`是Arduino库的关键组成部分。`MPU6050.h`是头文件,包含了定义传感器接口和函数声明。它定义了类`MPU6050`,该类包含了初始化传感器、读取数据等方法。例如,`begin()`函数用于设置传感器的工作模式和I2C地址,`getAcceleration()`和`getGyroscope()`则分别用于获取加速度和角速度数据。 在Arduino项目中,首先需要包含`MPU6050.h`头文件,然后创建`MPU6050`对象,并调用`begin()`函数初始化传感器。之后,可以通过循环调用`getAcceleration()`和`getGyroscope()`来不断更新传感器读数。为了处理这些原始数据,通常还需要进行校准和滤波,以消除噪声和漂移。 I2C通信协议是MPU6050与Arduino交互的基础,它是一种低引脚数的串行通信协议,允许多个设备共享一对数据线。Arduino板上的Wire库提供了I2C通信的底层支持,使得用户无需深入了解通信细节,就能方便地与MPU6050交互。 MPU6050传感器的数据包括加速度(X、Y、Z轴)和角速度(同样为X、Y、Z轴)。加速度数据可以用来计算物体的静态位置和动态运动,而角速度数据则能反映物体转动的速度。结合这两个数据,可以进一步计算出物体的姿态(如角度和角速度变化)。 在嵌入式开发领域,特别是使用STM32微控制器时,也可以找到类似的库来驱动MPU6050。STM32通常具有更强大的处理能力和更多的GPIO口,可以实现更复杂的控制算法。然而,基本的传感器操作流程和数据处理原理与Arduino平台相似。 在实际应用中,除了基本的传感器读取,还可能涉及到温度补偿、低功耗模式设置、DMP(数字运动处理器)功能的利用等高级特性。DMP可以帮助处理传感器数据,实现更高级的运动估计,减轻主控制器的计算负担。 MPU6050是一个强大的六轴传感器,广泛应用于各种需要实时运动追踪的项目中。通过 Arduino 或 STM32 的库文件,开发者可以轻松地与传感器交互,获取并处理数据,实现各种创新应用。博客和其他开源资源是学习和解决问题的重要途径,通过这些资源,开发者可以获得关于MPU6050的详细信息和实践指南
