Lessons of Japanese militarism's aggression must forever serve as alarm: spokesperson_我的网站

一 |     The devastation and tragedies brought by nuclear weapons should never repeat themselves, and the lessons of Japanese militarism's aggression and expansion must forever serve as an alarm, a Chinese foreign ministry spokesperson said Thursday.    Spokesperson Lin Jian made the remarks when answering a query regarding the 81st anniversary of the atomic bombing of Japan's Hiroshima, adding the Japanese side needs to face up to the concerns of the international community, and earnestly fulfill its nuclear non-proliferation obligations under international law.    On Aug. 6, 1945, the United States dropped the first atomic bomb on Hiroshima, accelerating the end of World War II. 81 years on, right-wing forces in Japan are gearing up to revive militarism. The Japanese authorities are rebuilding Japan's war machine, seeking to revise the three non-nuclear principles, and pursuing nuclear sharing with the U.S. side, even the possession of nuclear weapons.    The particular context of the nuclear explosions should all the more be remembered, Lin said, adding that right-wing forces in Japan have long been distorting historical facts, politically exploiting the nation's identity as a nuclear bombing victim for sympathy and deliberately downplaying Japan's invasion that killed and wounded tens of millions of people in Japan's neighboring countries, in an attempt to escape accountability for the war.    "More ironically, the Japanese authorities have been beefing up military buildup, seeking enhanced nuclear protection from the United States, and attempting to break free from the three non-nuclear principles," said Lin. He pointed out that a senior official at the Prime Minister's Office even clamored for Japan's independent nuclear armament, without even hiding the ambition for remilitarization.    This is a provocation to all peace-loving people in the world and reveals their contempt for historical justice, Lin said.    "This year marks the 80th anniversary of the start of the Tokyo Trials. The jury of history is still out and demands reverence from Japan," Lin said, adding the Japanese side should not once again stand before the court of history.                    。    

　    一键部署OpenClaw        网站慢，很多时候不是带宽不够，而是数据库查询慢。优化MySQL其实就两件事：加索引和用缓存。    先说索引。没索引的查询就是全表扫描，10万条数据能查出你服务器CPU飙到100%。加了索引，查询速度能提升百倍。    -- MySQL索引优化示例    -- 查看慢查询（找出需要优化的SQL）    SELECT * FROM mysql.slow_log    WHERE start_time > NOW() - INTERVAL 1 DAY    ORDER BY query_time DESC LIMIT 10;    -- 用EXPLAIN分析查询计划    EXPLAIN SELECT * FROM articles    WHERE category_id = 5 AND status = 1    ORDER BY created_at DESC LIMIT 20;    -- 如果type是ALL（全表扫描），就需要加索引    CREATE INDEX idx_category_status_time    ON articles(category_id, status, created_at);    -- 复合索引遵循最左前缀原则    -- 即：查询条件从左到右依次命中索引    再说缓存。领用最多的场景是Redis缓存。

二 | 把查询结果存到Redis里，下次查询直接从Redis取，不用查数据库。    # Redis缓存示例（PHP + Redis）    // 先查缓存    $redis = new Redis();    $redis->connect('127.0.0.1', 6379);    $cacheKey = 'article_list_page_' . $page;    $cached = $redis->get($cacheKey);    if ($cached) {    // 缓存命中，直接返回    echo $cached;    } else {    // 缓存未命中，查数据库    $articles = $pdo->query("SELECT * FROM articles ORDER BY id DESC LIMIT 20")->fetchAll();    $html = renderArticles($articles);    // 存入缓存，过期10分钟    $redis->setex($cacheKey, 600, $html);    echo $html;    }    MySQL本身也有查询缓存，在my.cnf里开启就行。但注意，数据更新后缓存不会立即失效，对实时性要求高的场景不适合。    # MySQL查询缓存配置（my.cnf）    query_cache_type = 1    query_cache_size = 64M    query_cache_limit = 2M    # InnoDB缓冲池大小（一般设为内存的70%）    innodb_buffer_pool_size = 2G    innodb_log_file_size = 256M    最后，定期清理数据库碎片和日志。数据量大了，碎片会导致查询变慢。每月跑一次OPTIMIZE TABLE就能解决。
