k3s 保平安，raspberry pi 集群可以组起来，咸鱼二手 100 出头一个 3b

怀旧贴，Tiny C Compiler 了解一下

这种方式写 C 的和 C++的用的多

很早我就在吐槽这个了

@Yut 20 现在毛病还有些，最近修复了不少但还是有少许问题

直接 run spider，默认直接命令行输出

@loading linux 怎么切全局，好像只能 iptables 或者路由器处理

@Jirajine 哦，好像是的，之前弄了好久，最后用的 GOPROXY

@shuigui 我随口说一了句，你要不要把我吊起来审判一下

@lsk569937453 我的意思是说用了 proxychains4 后就不用 goproxy 了，或者：

liuxu:～$ export GOPROXY=https://athens.azurefd.net/

这是我以前用的，不知道现在还有没有效果，或者其他第三方：

@Livid 275 天前的帖子再被翻出来在“程序员”节点置顶。。很多人对此帖意见颇深

楼上的各位知不知道苹果要把 x86 换成 arm 了。。

用 proxychains-ng，你这个就是被墙了

@Livid 这类在 v2 持续发贴，往自己博客引，然后博客强制关注公众号才能观看全部内容，算推广么

有钱会这么为难吗？加钱。

@louettagfh #10 https://man7.org/linux/man-pages/man2/mmap.2.html

mmap() creates a new mapping in the virtual address space of the calling process. The starting address for the new mapping is specified in addr. The length argument specifies the length of the mapping (which must be greater than 0). If addr is NULL, then the kernel chooses the (page-aligned) address at which to create the mapping; this is the most portable method of creating a new mapping. If addr is not NULL, then the kernel takes it as a hint about where to place the mapping; on Linux, the kernel will pick a nearby page boundary (but always above or equal to the value specified by /proc/sys/vm/mmap_min_addr) and attempt to create the mapping there. If another mapping already exists there, the kernel picks a new address that may or may not depend on the hint. The address of the new mapping is returned as the result of the call. The contents of a file mapping (as opposed to an anonymous mapping; see MAP_ANONYMOUS below), are initialized using length bytes starting at offset offset in the file (or other object) referred to by the file descriptor fd. offset must be a multiple of the page size as returned by sysconf(_SC_PAGE_SIZE). After the mmap() call has returned, the file descriptor, fd, can be closed immediately without invalidating the mapping.

@zxc1234 找运营商买套餐，企业有企业专线，金融有额外独立专线

1.不是，看指标
2.是，不过我们说的专线没你这么专
