LastPass exposed 0-day vulnerabilities, allowing accounts to be accessed by malicious websites
Google Project Zero hacker Tavis Ormandy reported a high-risk 0-day vulnerability was found in the popular password management tool LastPass, allowing malicious websites to fully access users' accounts. The vulnerability has been reported to LastPass, but the details a
Recently the Sony incident has been a buzz, to prevent hackers first from the upgrade password start. Since the development of the need for the general use of Firefox as the default browser, a long time to install the LastPass password Manager as a prerequisite add-on, when registering to click Alt+g will help you to generate a very high complexity of the password, and then save the password. This avoids the practice of many people using the same pass
Of course, this local application includes all the Web features you can expect, such as logging into your favorite pages and accounts, or automatically modifying their passwords. In addition, OS x applications also have a few secret secrets.
First, you can log on to the Web site immediately before you start the browser (with the help of OS X's Quick Search feature), followed by the security check feature, which helps users continuously monitor their password strength.
Finally,
Preface: December 2014, sophomore last semester, the computer composition Principle course design, I wrote some machine instructions, and even designed some micro instructions (extended instruction set, write to the control memory inside), think that I was very strong ...
PS. Just finished the microcomputer interface course Design report, the microcomputer interface reminds me of the principle of computer c
Experimental conclusionLab missions (1)1. Write instructions to memory using the e commandFirst use the e command to the memory unit starting from 1000:0 to write the task requirements of the machine code, and then use the R command to see the register status in the CPU, you can see, CS=073FH, ip=0100h, point to memory 073f:0100, and then use the R command to modify CS, IP content, so that CS : IP points to 1000:0. Then use the T command to execute th
Preface:In the previous section we learned the interaction between the instruction and the controller by adding an action to the instruction and invoking the method in the controller. In this section we learn how the instructions and instructions between the interaction, we through a small game to learn with everyone, listening to the desert teacher said this is a foreign person to write the demo, we can le

When configuring PHP5 to use MySQL as a database, many people think that as long as the php.ini to add Extension=php_mysql.dll, the instructions can not understand why many articles are recommended to add EXTENSION=PHP_ Mysqli.dll of the order;
Just look at the official latest PHP manual, which says:
The following is a built-in list of extension libraries:
The following modifications are available in PHP 5 (up to 5.0.4). New built-in: DOM,LIBXML,IC

$_server instructions for use in PHP, php_server instructions for use
PHP programming often need to use some of the server's information, special $_server detailed parameters to organize, convenient for later use.
$_server[' php_self ') #当前正在执行脚本的文件名, related to document root. $_server[' argv '] #传递给该脚本的参数. $_server[' argc '] #包含传递给程序的命令行参数的个数 (if run in command-line mode). $_server[' Gateway_interface ')
Debug Command supplement
In executiondThe command can contain the address parameter (segment address: Offset address), where the segment address is first sentdsRegister and then hand it over to the processor.
Therefore,dThe command can also be used as follows:d SR:offset(SR refers to segment register)For example:
-R ds: 1000-d DS: 0; view the content in the memory range starting from 1000:0
-R ds: 1000-d DS: 10 18; view 1000:10 ~ Contents in
-D Cs: 0; view the instruction code in the current Cod
