How to Access Arduino Video Stream Over Internet I’m working on an Arduino project that capture video and stream the video via web service. The ESP32-CAM moduel is ready-to-use and it provide a web service in LAN (e.g. access it via 192.168.1.11). I hope to access this video streaming web service from Internet. I’m familiar with the process of accessing local network service via LAN exposing services like FRP or Ngrok. I hope to find some frp-like open source code that is compatible with Arduino.

Draw graph(network) with nx_pydot in networkx with nx_pydot in nx.drawing, we can have more plotting style of network/ tree/ graph. Here is a simple sample: import networkx as nx g=nx.DiGraph() edgelist = [(0, 1), (1, 12), (2, 12), (3, 17), (4, 11), (5, 4), (6, 10), (7, 12), (8, 14), (9, 14), (10, 11), (11, 14), (12, 11), (13, 17), (14, -1), (15, -1), (16, 10), (17, 11), (18, -1)] g.add_edges_from(edgelist) p=nx.drawing.nx_pydot.to_pydot(g) p.write_png('pydot_Tree.png') the plot result:

How to Share Wired Internet Via Wi-Fi and Vice Versa on Linux Aaron KiliApril 15, 2020 CategoriesNetworking Commands Leave a comment In this article, you will learn how to share a wired (Ethernet) internet connection via a wireless hotspot and also how to share a wireless internet connection via a wired connection on a Linux desktop. This article requires you to have at least two computers: a Linux desktop/laptop with a wireless card and an Ethernet port, then another computer (which may not necessarily be running Linux) with either a wireless card and/or an Ethernet port.

写在前面：Arm板卡上的 BT 下载器得可以通过web进行操作才比较方便。所以人家推荐了 Deluge 这款工具。 references: Installing Deluge on the Raspberry Pi 7 Best BitTorrent Clients for Linux in 2020 Installing Deluge on the Raspberry Pi by Emmet Jul 30, 2019 Updated May 03, 2020 Beginner In this Raspberry Pi Deluge project, we will show you how to set up the popular Deluge torrent client on the Pi. Throughout this tutorial, we will be showing you how to install and configure the Deluge torrent client alongside the Deluge web interface.

Ubuntu「一键」设置全局代理 sonictl note: the DNS problem may be still there. Except proxychains. WSL (Windows Subsystem for Linux) or Ubuntu is OK for this tutorial. Other linux can also try this. 1. Windows first Proxifier –> Clash Walls on UWP apps: Use Fiddler WinConfig tool to disable it. WSL: 使用 SSTap 直接接管 Windows 除了 Windows 系统进程以外的网络层，当然也包括 WSL Proxifier 并不能实现对 WSL 启用代理 相对最完美的方法是使用 Proxychains, 但不方便 直接在终端配置 proxy， 如果在WSL上使用的app不多。 2. Linux, WSL： Configure proxy in Terminal two lines of cmds： export ALL_PROXY="socks5://127.0.0.1:1080" export all_proxy="socks5://127.

你还在想用 nextCloud 自建NAS? 何不试试P2P Sync? Are you still using nextcloud as your NAS solutions？ Why not use P2P Sync? Why do you need to ditch nextcloud, owncloud, seafile? In a word, it’s too heavy! Deployment trouble! Synchronization requires too much intranet penetration, simple port mappings often lead to file synchronization errors, and deployments on ARM don’t always guarantee Smooth, blah blah blah various holes. Peer-to-Peer Sync Try VerySync, a product based on the P2P Sync design philosophy, which was born to be placed on your router, your computer and your laptop.

. . . 你真的认为大学的牛逼与否是看高考分数排名？是看某个权威杂志发布的专业排名？ . . . 什么是排名？能不能有点自己的判断？ 我的指标： 1. 大学的综合能力看什么： 两院院士人数 国家自然科学基金（各种项目，比如重点项目，杰青项目）的获取资助个数。 待续。 2. 专业能力看什么： 某个专业国际最顶级，最权威期刊、会议，论文数。 某个专业下，是否有杰青（这一条就说明问题了） 博导的博士毕业人数，招录人数，历年统计。（这一条可以发现很多问题😀，人说我考大学，看博导作甚？博导就是专业能力的代表。）

During my time with Zotero, I’ve really enjoyed its various features and the 300MB of file sync space is able to be extended by modifying the path to a synchronized folder under oneDrive or dropBox. reference: Extending Zotero’s syncing folder size by DropBox However, I often get lost when jumping between papers. After jumping from paper A to paper B, I am unable to go back to paper A if I forget its name. I wish I could write an extension to add a history feature for paper viewing.
