I tried this: cql = "Insert into table_name (my_key, name, my_dict) values (%s, %s, %s)" % (my_key, name, my_dict) session.execute(cql) This obviously didn't work. I already have a map type column in my column family. How do I go about it? Error: TypeError: not all arguments converted during string formatting 回答1: Use parameter passing form instead of string interpolation: cql = "Insert into table_name (my_key,

Jupyter Notebook Low CPU Usage

问题 I have noticed that some cells take a long time to finish executing on my Jupyter Notebooks. When looking in the task manager, I see that the python process is only using up to about 4% of the CPU. I am using Python 3.6.2 I am on Windows but am using the "Bash on Ubuntu on Windows" terminal to launch the Jupyter notebook (maybe this helps). The processor is a Core i7 and the process is not using up all available RAM so it isn't a Swap memory problem. Basically, why is it being "throttled"

本文作者： 牛睾 ﹀ ﹀ ﹀ 事情起因，在暗网中，发现一个帖子，说是极速FQ软件，我就下来看看，没成想到这是一个木马文件。我双击后，过了 2 秒，没有任何反应（ 360 也没报警），这太反常了。我立马断网分析这个程序。 病毒下载地址： https://mega.nz/#!9 ***** ***** ***** ***** EXEslqtgjCSeWQyMTrh9g0 下载后得到 一看体积，就知道不是翻墙工具（可我还是手贱点了），接着查壳，获取到如下软件信息 发现是 c# 的程序。果断反编译，得到如下代码 根据代码可知，木马会从网络上下载一个名为 setup.batt 的批处理文件，该文件内容如下。 同时会下载另一个名为 ed_s.exe 的木马文件，下载成功后，批处理注册服务，开机启动。 接着查看 ed_s.exe 的信息 可知该木马也是 c# 编写的。接下来反编译该木马文件，得知以下代码 这个时候可以猜到，这个木马文件会跟远程 ftp 服务器连接。接着寻找 ftp 服务器信息，获取到如下信息 接下来远程连接他的 ftp 服务器，发现上面有很多受害者电脑上的敏感文件。经过查看木马代码，此木马会自动扫描受害者电脑并上传 xls|doc|rar|txt|xlsx 文件 他服务器内受害者的敏感文件如下，红箭头指向的是我的电脑文件，手还是慢了。钱包文件被木马上传到他服务器了。
