Python exception handling: rescuing code black holes
1. Introduction Exception handling is a crucial skill in Python development. When an error or abnormal situation is encountered while the program is running, reasonable exception handling can protect the program from crashing and provide error information so that we can debug and repair it in time. This article will delve into the importance of […]

[MIT6.824] Lab 3: Fault-tolerant Key/Value Service
[MIT6.824] Lab 3: Fault-tolerant Key/Value Service Goals Build a disaster-tolerant KV database through the Raft library implemented in Lab2. The services that need to be implemented have three operations: Put(key, value) Both key and value are strings, and put sets the value of the specified key. Append(key, arg) Append arg to the value corresponding to […]

51+OLED IIC hand-torn Ai Kun (128*64 self-drawn Kun picture, open source)
In a trance, I seemed to hear my husband’s famous songs back then, and I couldn’t help but sigh. I am writing this article to express my nostalgia! Finished product effect: Start: Reach out and touch the SSD1306_OLED in the corner. Start: 1. Since the SSD1306_OLED module supports the IIC protocol, if you want to […]
KeepAliveTime analysis in ThreadPoolExecutor
keepAliveTime is the time that idle threads in the thread pool wait for tasks. If this time is exceeded, the thread pool will kick the current thread out of the thread pool. Divided into two scenarios: allowCoreThreadTimeout is set to true. After all idle threads in the thread pool time out, getTask() returns null, and […]
