                Try Rust for Linux
              
          
    My note for trying rust-for-linux.
Prepare environment

Here I take arch linux as an example, and I assume you already installed rust and put ~/.cargo/bin inside your PATH.
cd /some/where

# Install requirements
sudo pacman -Syuu --noconfirm bc bison curl clang diffutils flex git gcc llvm libelf lld ncurses make qemu-system-x86 cpio
export MAKEFLAGS="-j32"

                Gemini API load balancer
              
          
    基于 Cloudflare Workers 的 Gemini API 负载均衡器

这是一个部署在 Cloudflare Workers (Serverless) 上的轻量级 Gemini API 负载均衡器和代理。
本项目通过实现 随机密钥选择与重试 (Random Key Selection & Retry) 策略，解决了 Gemini API 免费层级严格的速率限制问题。它暴露了一个 兼容 OpenAI 的端点，允许与支持 OpenAI SDK 的客户端（如 EasyDict）集成。
部署


创建 Worker： 前往 Cloudflare Dashboard 并创建一个新的 Worker（点击"从 Helloworld 开始"）。
部署代码： 将提供的代码粘贴到 Worker 编辑器中。

    A reverse proxy for Telegram Bot API on Aliyun Function Compute / Cloudflare Workers

To help users in China mainland access telegram api stably and conveniently with low cost, this script maybe the one you need.
The server-less means you don't have to run a server to proxy the requests, just pay as you go.
Usage

Edit key_prefix, set it to the prefix of you bot address(like /bot563441998:) can avoid abusing.

    Policy Routing VPN with Tinc and Nftables

This is just a personal backup, but if it helps you, that's even better.
Target


Make linux work as a router.
For domestic targets, connect them directly.
For traffic that need to bypass the firewall, use VPN.

    Pwnable.kr echo1 writeup

ihciah@gmail.com
At first glance, I thought there are 3 ways to exploit this problem, since it gives me 3 choices: BOF, FSB, UAF, however, the last two are not available.
In echo1, it calls get_input to input 128 input, but the buffer equals to bp-20h, so it can only save data with max length of 32.
Above the return address is the old rbp, so we can write 32 + 8 trash and an address to jump to to overflow it.
After searching with jmpcall si in peda, we found no result.
