是否有可能以某种方式让X轴上的值在matplotlib中以十六进制表示法打印？对于我的绘图,X轴表示内存地址.
谢谢.
我最近在我的archlinux盒子上安装了mariadb,并希望用不同的数据和tmp目录运行mysqld
[mysqld]
user = mysql
port = 3306
datadir = <datapath>
tmpdir = <datapath>/tmp
运行mysqld时,我收到以下错误消息:
InnoDB: The InnoDB memory heap is disabled
InnoDB: Mutexes and rw_locks use GCC atomic builtins
InnoDB: Compressed tables use zlib 1.2.8
InnoDB: Using Linux native AIO
[ERROR] mysqld: Can't create/write to file '<datapath>/tmp/ib8dOkCX' (Errcode: 13)
InnoDB: Error: unable to create temporary file; errno: 13
[ERROR] Plugin 'InnoDB' init function returned error.
[ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed.
[ERROR] mysqld: Can't create/write to …如何使用 tcpdump 捕获流量并仅以原始二进制格式保存完整的有效负载（应用程序层数据，无 tcp/ip 标头）？
我试图从PE文件(一个DLL)中提取.text部分,即代码.在Linux或某些python或ruby lib中是否有任何简单的工具可以让我轻松完成这项工作？
我想知道是否可以在数组中保存一些ruby语句,如:
a = 1
b = 0
statements = ['a += 1','b = a + 4']
statements.each { |s| s.execute }
我想要这样做的原因是能够使用Array置换来执行数组中语句子集的每个组合.
也许我让自己变得困难,并且有一种更简单(也许更明显)的方式.
感谢任何帮助.
我安装了1.7.4,然后将其解压缩到〜/ go并相应地设置GOROOT.我还创建了〜/ work/src/github.com/user/hello并相应地设置了GOPATH.
从https://golang.org/doc/install#testing尝试hello world示例时,我收到以下错误:
$ go install github.com/user/hello
../work/src/github.com/user/hello/hello.go:3:8: cannot find package "fmt" in any of:
/home/user/go/src/pkg/fmt (from $GOROOT)
/home/user/work/src/fmt (from $GOPATH)
package github.com/user/hello
imports runtime: cannot find package "runtime" in any of:
/home/user/go/src/pkg/runtime (from $GOROOT)
/home/user/work/src/runtime (from $GOPATH)
检查〜/ go,我在〜/ go/src/fmt中找到fmt而不是〜/ go/src/pkg/fmt
感觉我错过了至关重要的事情.感谢您的帮助.
