Hints

  • 无线电干扰 Radio Susceptibility

      Abstract: Engineers often wish that radio susceptibility (RS) or radio immunity could be cured with an antibiotic, a vaccine, or someform of cure-all. Unfortunately, solving the RS problem is not that easy. Indeed, the laws of physics apply. In this article we discusssources of RS. We also offer tips and Hints to protect systems, power supplies, printed circuit boards (PCBs), and electroniccomponents from radio frequency interference.

  • This paper addresses the subject of SQL Injection in a Microsoft SQL Server/IIS/Active Server Page

    This paper addresses the subject of SQL Injection in a Microsoft SQL Server/IIS/Active Server Pages environment, but most of the techniques discussed have equivalents in other database environments. It should be viewed as a "follow up", or perhaps an appendix, to the previous paper, "Advanced SQL Injection". The paper covers in more detail some of the points described in its predecessor, providing examples to clarify areas where the previous paper was perhaps unclear. An effective method for privilege escalation is described that makes use of the openrowset function to scan a network. A novel method for extracting information in the absence of helpful error messages is described the use of time delays as a transmission channel. Finally, a number of miscellaneous observations and useful Hints are provided, collated from responses to the original paper, and various conversations around the subject of SQL injection in a SQL Server environment.

  • VxWorks 6.6 BSP开发执导 This document describes, in general terms, the elements that make up a board

    VxWorks 6.6 BSP开发执导 This document describes, in general terms, the elements that make up a board support package [BSP], the requirements for a VxWorks BSP, and the general behavior of a BSP during the boot process. This document outlines the steps needed to port an existing BSP to a new hardware platform or to write a new VxWorks BSP for custom hardware using a reference BSP or template BSP as a starting point. It provides Hints and tips for debugging a BSP and solving common BSP development problems. It also provides information on the BSP validation test suite [BSP VTS] that is used to assess the functionality of a VxWorks BSP.
