A New Internet


Governance Minimization by building protocols, not platforms.





Facebooks owns 80% mobile social traffic. Google owns 92% of search and Amazon Web Services is bigger than their next four competitors. No one can survive from these monopolies.

They track our every move, they monitor every moment in our lives, and-and they exploit our data for profit. And you can ask them all the questions you want, but they're not gonna change, they don't have to.

These companies are kings, and they rule over kingdoms far larger than any nation in human history. They won, we lost.

So, why am I here? Because look at where we are. Yeah? - We are in the nation of the Freedom, Taiwan, a government that was founded by people who were, at one point, ruled by kings they couldn't overthrow.

So, what did they do, right? They started over. They came here, to the New World. World 2.0, version 1949.

And the way we win is by creating a new, democratic, decentralized Internet, one where the behavior of companies like this will be impossible, forever. One where it is the users, not the kings, who have sovereign control over their data.

This, I promise to you: I will help you end this tyranny by building an Internet that is of the people, by the people, and for the people, so help me God.

Git 注意事項

使用 Git 的一些技巧 1. git pull 的時候可以用 --rebase 比較不會有多餘的 merge point 2. 善用 squash commit,squash 完心情都很好 3. commit 之前一定要先 format code 一次,不然多出來的 reformat commit 會很難整理 4. 拆 commit,盡可能讓每個 commit 都可以 build & test,也比較好回到上游 5. 如果 local 修改的整理過的 commit tree 要 rebase 上去就只能用 rebase onto e.g., git fetch upstream git checkout -B local-rebase-branch upstream/feature/binance-futures git rebase -i upstream/main .... 改改改 git push -f origin HEAD -B 會洗掉原本就有的 local branch CS Visualized: Useful Git Commands Code Cleanup: Splitting Up git Commits In the Middle of a Branch Git rebase --onto an overview 30 天精通 Git 版本控管

Engineer + Trader can be something else

尋找 Alpha ! 我們的核心目標是透過不斷地進行市場研究來建立交易策略,再透過程式進行相對高頻的交易,而這些策略是必須具有可重複、可規模化等特性。 常見流程如下: 一、研究數據 在研究的工作上,我們會透過觀察數據找出最佳潛在的交易機會 — — Alpha 。 二、發想交易策略 基於交易訊號來建立「交易策略」,通常好的訊號要有很穩固的策略基礎原理,也就是核心邏輯,如果從數據直接推倒訊號,則有點倒因為果。 三、寫程式進行自動交易 最後,利用交易策略來編寫程式進行自動化交易,這階段的重點是「回測」,回測在未來不一定適用,但不回測就沒信心上線。並透過交易的結果持續優化策略。 以我最近(從2021/9/22開始),投入 BTC/USDT 這個 trading pair $5000 USD 的小額試單為例: 首先,比特幣市場特性為 1. 用戶在合約市場可以輕易開高倍槓桿 2. 由於行業缺乏監管,主力可以來回收割散戶籌碼,精準打止損爆倉是家常便飯(所謂價格不變,倉位不見) 3. 存量市場,博弈性質強烈 永遠是散戶賠錢,握有交易數據與龐大資金的量體的主力賺錢 開空的散戶多了,就漲了 開多的散戶多了,就跌了 根據上述先驗知識,我們在想有沒有辦法可以預先解析主力動向?很難。但我們只要知道大部分散戶在做什麼,反著做就可以了!為什麼?因為 BTC的價格會傾向往阻力最小的方向移動。 那什麼是阻力最小?我們得先有一個假設: 散戶喜歡開高倍槓桿,主力機構一般不開槓桿! 多頭槓桿倍率高 ⇒ 多頭車重,容易翻車; 空頭槓桿倍率高 ⇒ 空頭車重,容易翻車 e.g., 空頭平均槓桿是2倍; 多頭平均槓桿是20倍。那麼機構傾向空方,因為拉 -5% 比 拉 +50% 容易 在大多數時候,多空槓桿倍率不會相差太多,但若行情到了關鍵位置:往往多空倍率會嚴重失衡! 這時候選擇當槓桿倍率高的對手方⇒賺錢機率基較高。 該如何知道哪邊的槓桿倍率比較高? 由眾多期貨數據組成,其中一個重要是資金費率。 永續合約的資金費率 在加密貨幣衍生品市場,有一種特別的期貨,它的特色是沒有到期日。所以引入資金費率來平衡價格,用來促使促使永續合約貼近現貨價格的一種機制。 合約價格高於現貨價格時: 資金費率為正 多方支付空方利息 促使多方平倉,賣出手中的合約⇒降低價格 合約價格低於現貨價格時: 資金費率為負...
