Picking the right architecture = Picking the right battles + Managing trade-offs
This script is intended to be used with the ics files outputted by myStudies, to make importing your schedule into your calendar easier.
myStudies does not export recurring events, but instead individual events for every date. This makes it hard if you want to edit them, because you can't edit them as a series.
Call this script with these arguments:
See dejavuln-autoroot for a simpler exploit that works on webOS 3.5+ TVs (i.e., models from 2017 and later). It is unpatched as of 2024-04-21 and does not require Developer Mode or even a network connection—just a USB drive.

关于比特币套利交易的文章，坊间一搜一大堆，尤以 2014，2015 为甚。那时交易所间价差相当可观，套利的机会很多，躺着赚钱并非难事。如今，套利区间收窄，留在沙场上的估计只剩下大玩家，想要不费力气躺赢机会渺茫。最近帮朋友牵线寻找币圈量化交易的机会，本欲做个打酱油的中间人，事了拂衣去，安安静静做个三河市微胖界扛把子，谁料还是一时技痒，不小心昨夜搭进去六七个小时。
关于如何做套利交易，我就不赘述，大家可以看这篇文章，有内容有故事：https://daily.zhihu.com/story/4831821。
本文没有故事，只有技术和产品上的分析。
既然要做可行性分析，那么第一步就是观察交易数据。国内的交易市场虽然在政策要求下清场出局，国外的交易市场还算红火。从 bitfinex，kraken 一路到 bithumb，korbit 等，都提供 rest API，少量提供 websocket 接口。虽然文档欠缺，但这些接口都很简单，上手并不困难。
