CAT5110/18/19/23/24/25 linear-taper digitally programmable potentiometers perform the same function as a mechanical potentiometer or a variable resistor. These devices consist of a fixed resistor and a wiper contact with 32-tap points that are digitally controlled through a2-wire up/down serial interface.
The XL6003 regulator is fixed frequency PWM Boost (step-up) DC/DC converter, capable ofdriving 1050mA load current with excellent line and load regulation. The regulator is simple to use because it includes internal frequency compensation and a fixed-frequency oscillator so that it requires a minimum number of external components to work. The XL6003 could directly drive 5~10 3W LED units at VIN=12V.

Abstract:
To overcome drawbacks of ASIC such as fixed functionality and upgrade difficulty, FPGA was used to realize the core functions of STEL-2000A. This paper used the DDS IP core provided by ISE to realize the NCO module, called hard core multiplier and implemented CIC filter in the down converter, described the principle and implementation detail of the demodulation of DQPSK, and derived a simple method to introduce a fixed phase shift of ?仔/4. The VHDL source code was designed by modularity method , and the complete system was successfully implemented on Virtex-II Pro development board. Test results indicate that this system successfully realize the core function of the STEL-2000A.

I. Introduction
This code exploits a previously undisclosed vulnerability in the bit string
decoding code in the Microsoft ASN.1 library. This vulnerability is not related
to the bit string vulnerability described in eEye advisory AD20040210-2. Both
vulnerabilities were fixed in the MS04-007 patch.

. kill-bill : Microsoft ASN.1 remote exploit for CAN-2003-0818 (MS04-007)
by Solar Eclipse <solareclipse@phreedom.org>
Usage: kill-bill -p <port> -s <service> host
Services:
iis IIS HTTP server (port 80)
iis-ssl IIS HTTP server with SSL (port 443)
exchange Microsoft Exchange SMTP server (port 25)
smb-nbt SMB over NetBIOS (port 139)
smb SMB (port 445)
If a service is running on its default port you don t have to
specify both the service and the port.
Examples: kill-bill -s iis 192.168.0.1
kill-bill -p 80 192.168.0.1
kill-bill -p 1234 -s smb 192.168.0.1

DVBstream is based on the ts-rtp package available at
http://www.linuxtv.org. It broadcasts a (subset of a) DVB transport
stream over a LAN using the rtp protocol. There were a couple of
small bugs in the original ts-rtp application, which I have fixed
here.
Following is a repost of the public domain make that I posted
to net.sources a couple of months ago. I have fixed a few bugs, and
added some more features, and the resulting changes amounted to
about as much text as the whole program (hence the repost).一個(gè)編譯器C代碼，詳見REDME。
