經過一周多的時間，終于完成的我的這個KTV項目，說實話，做這個項目我收獲了不少，難點也非常多，不過經過重重磨難，總算是過來了。不簡單呀！
這個項目主要分為前后臺。
前臺主要實現的功能是：歌星點歌，拼音點歌，字數點歌，
類型選擇，金曲排行，一些切歌，重唱，已點歌曲列表，主要是這些功能。
后臺主要實現的功能是：增加歌手，增加歌曲，修改歌曲路徑，修改歌手圖片路徑。
首先先看前臺：
前臺核心類：

CUDA之通用矩陣乘法：從入門到熟練！
Mar 25, 2024 pm 12:30 PM
通用矩陣乘法（GeneralMatrixMultiplication，GEMM）是許多應用程序和算法中至關重要的一部分，也是評估計算機硬件性能的重要指標之一。通過深入研究和優(yōu)化GEMM的實現，可以幫助我們更好地理解高性能計算以及軟硬件系統(tǒng)之間的關系。在計算機科學中，對GEMM進行有效的優(yōu)化可以提高計算速度并節(jié)省資源，這對于提高計算機系統(tǒng)的整體性能至關重要。深入了解GEMM的工作原理和優(yōu)化方法，有助于我們更好地利用現代計算硬件的潛力，并為各種復雜計算任務提供更高效的解決方案。通過對GEMM性能的優(yōu)

AI攻克費馬大定理？數學家放棄5年職業(yè)生涯，將100頁證明變代碼
Apr 09, 2024 pm 03:20 PM
費馬大定理，即將被AI攻克？而且整件事最意味深長的地方在于，AI即將解決的費馬大定理，正是為了證明AI無用。曾經，數學屬于純粹的人類智力王國；如今，這片疆土正被先進的算法所破譯，所踐踏。圖片費馬大定理，是一個「臭名昭著」的謎題，在幾個世紀以來，一直困擾著數學家們。它在1993年被證明，而現在，數學家們有一個偉大計劃：用計算機把證明過程重現。他們希望在這個版本的證明中，如果有任何邏輯上的錯誤，都可由計算機檢查出來。項目地址：https://github.com/riccardobrasca/flt
