New art project.
Train and inference GPT in 243 lines of pure, dependency-free Python. This is the *full* algorithmic content of what is needed. Everything else is just for efficiency. I cannot simplify this any further.

稍微整理了一下知識才發現，其實 coding interview 會被大家搞成這樣真的是 pathetic 的；今天之所以轉職仔/NG 會對 LeetCode 苦手，我認為答案只有：

@johnny____11 已經私訊回過了，這邊公開貼出來給大家參考。

1. 收入的10%拿來做保險。(非投資型，純保障)
2. 收入的30%拿來投資。
3. 收入的60%拿來生活過日子，包含房貸、房租、車貸等。

這30%的投資裡面，再來做所謂的「資產配置」

If you want to protect your "knowledge files", avoid enabling the Code Interpreter and making your @OpenAI GPTs public.

The /mnt/data directory is shared across all ChatGPT sessions, allowing you to easily list and download files in a standard ChatGPT session.

雖然去年學完了 Rust 的 tutorial，但想了很久，覺得如果真要做產品，如果不是非 Rust 不行做的理由，應該還是不會用 Rust 寫。 主要原因就是軟體圈的東西真的太捲了，迭代太快，用 Rust 可能都還沒寫完，還在計較怎麼寫比較漂亮，隔壁用 PHP 寫說不定不用花到1/4時間就寫完了，甚至可能外面競爭者都換完一輪了 😂

如果是一個都還不確定能賺錢的產品，真的不要燒太多時間下去做，年紀越大會越知道時間的寶貴。

世界上多得是程式碼寫得很漂亮最後寫完根本不能賺錢就放著爛的產品。 有朋友公司以前做一個大型專案，十幾二十人在做，全部用 C++ 寫，最後全部寫完，就擺著。 😂

2011 年的時候我開始寫 Go，2012 年時我說用 Go 再戰十年應該沒問題，結果確實如此，沒有投資錯誤 😂 後來 Kubernetes 紅起來，帶動了整個生態發展，Go 相關的徵才也越來越多。

主要原因也不是說 Go 真的好棒棒還什麼的，是以前寫 C, C++ 過來，C/C++ 的效能當然是極致的好，但要開發就是會有很多苦工，而 Go 就是能做到在效能與開發效率間取得最好平衡的工具，有寫過 C/C++ 的人過來寫 Go 基本上寫出來的東西真的都不會差。

評估「一個工程師是否足以足夠資深」的標準中，常常有一項叫做「能否完成複雜的設計」

但我沒聽過有標準是「能否把複雜的設計變簡單」，或者甚至「能否避免過度複雜的設計」

通常這樣會被認為你能力不夠，或者不想學新東西🫠

因此傾向把複雜的東西「講」得很簡單的人就反過來比較吃香。

How do processes talk to each other on Linux?

The diagram below shows 5 ways of Inter-Process Communication.

1. Pipe
Pipes are unidirectional byte streams that connect the standard output from one process to the standard input of another process.

2. Message Queue
Message queues allow one or more processes to write messages, which will be read by one or more reading processes.

3. Signal
Signals are one of the oldest inter-process communication methods used by Unix systems. A signal could be generated by a keyboard interrupt or an error condition such as the process attempting to access a non-existent location in its virtual memory. There are a set of defined signals that the kernel can generate or that can be generated by other processes in the system. For example, Ctrl+C sends a SIGINT signal to process A.

4. Semaphore
A semaphore is a location in memory whose value can be tested and set by more than one process. Depending on the result of the test and set operation one process may have to sleep until the semaphore's value is changed by another process.

5. Shared Memory
Shared memory allows one or more processes to communicate via memory that appears in all of their virtual address spaces. When processes no longer wish to share the virtual memory, they detach from it.

預留擴展空間, 大概只有跟 domain 很熟的人才有機會實現, 講白了就是同樣的東西你做過看過了

對於未知是無法掌控的,程式要做的不是預留,而是花功夫降低未來修改的成本,讓程式碼彈性好改

你要好改就是要架構好, 要架構好就是慢慢琢磨, 也就是要常重構. 怎麼常重構?要寫測試
