Aggregator

We’ve developed an energy-based model that can quickly learn to identify and generate instances of concepts, such as near, above, between, closest, and furthest, expressed as sets of 2d points. Our model learns these concepts after only five demonstrations. We also show cross-domain transfer: we use concepts learned in a 2d particle environment to solve tasks on a 3-dimensional physics-based robot.

这个最终的效果呢，就是可以通过手机连接上esp8266创建的wifi，然后连接其创建的服务器，发送特定指令就可实现遥控开门 （做工比较粗糙还请不要见笑...） 一、原理 其实这个一看就会明白，非常简单的，由Arduino连接一个舵机和一个esp8266模块，esp8266工作为AP模式，发出热点信息

一、接线 其中信号线PWN接arduino上任意带波浪号的引脚都可，我这里选择的是10号引脚，注意在程序中绑定的引脚要和连接的引脚相同 二、上传程序

esp8266-01调试 一、硬件设备 1.USB转TTL 2.esp8266-01 3.杜邦线 4.电脑 二、接线 按表格接好线如下 三、调试 把usb转ttl模块插入电脑，在 此电脑-管理-设备管理器 中查看该设备端口号 若是出现上图的黄色箭头警告，就卸载原usb转ttl驱动，重新下载ft232

Introduction This paper was published in CCS 2015. With the introduction of the various mitigation deployed in the user space, especially sandbox, the vulnerability in the linux kernel has become a target of the attacker. However, the memory space in the kernel is hard to predict since the kernel space are used by various tasks. […]

No single defense is perfect, but with the right set of diverse, overlapping controls, most threats can be rebuffed.

也是经过一通扫描和测试，没发现其他有用信息，感觉这是个sql注入。其实对于二阶sql注入我以前没实践过，也没看过资料，只是知道这个名字，但不知道为何看到这道题就让我回想起了这个名词，所以查了一下二阶sql注入的资料：二阶sql注入。简单来说，就是第一次构造的恶意数据直接储存到了数据库中，但在其他地方

这道题其实是考jsp和java的，我没学过jsp，java倒是有一点了解，但是刚拿到题的时候还是看不懂java代码里的内容，所以去简单学习了下jsp（jsp教程），按照教程里的步骤搭建了eclipse 环境并打开这道题提供的项目源码在本地进行调试，然后又去百度了源码中的各个java函数，大致理解了整

首先观察这个web应用的功能，可以任意留言，也可以搜索留言，当然我还用cansina扫描过网站，查看过源码，抓包查看过header等。没发现其他提示的情况下断定这就是个sql注入，可能存在的注入点呢，就是留言时产生 insert into 注入，或者搜索时产生的 like '%xx%' 注入。经过多

We’ve developed Random Network Distillation (RND), a prediction-based method for encouraging reinforcement learning agents to explore their environments through curiosity, which for the first time exceeds average human performance on Montezuma’s Revenge.
