理解並使用 Golang 的 “omitempty” 特性
在使用 Go (Golang) 並將數據編碼爲 JSON 時,您可能會遇到這樣的情況:如果某些字段的值爲空,則需要從編碼輸出中省略這些字段。這就是 Golang 的 omitempty 功能發揮作用的地方。struct 字段標記中的 omitempty 選項會告訴編碼器,如果字段爲空值,則跳過該字段。什麼是 “Empty Value”?在 Go 中,Empty Value 的定義是:布爾類型爲 ⌘ Read more

It took me so long to find the cause of a memory leak in GoBlog. I thought it was smart to use a cache for prepared database statements. But I didn’t read the documentation and didn’t know that prepared statements need to be closed when they are no longer needed to free up the allocated resources. 🤦♂️ I finally fixed it by removing the prepared statement cache altogether. Less code, fewer problems in the future, and the cache wasn’t much of an improvement anyway. I also learned about the usefulness of memory profil … ⌘ Read more

钢铁雄心4 非作战状态时,部队的装备损耗怎么看?
德国兵在西伯利亚深处的战壕中等待指挥部命令,前面是茫茫雪原,后面是还在顶着轰炸修16000锤的补给中心和铁路。
营地里出发的时候有2000套枪。每天没吃的,还好说,因为这个世界是不吃饭不换衣服的。就是有点冷,烧枪托取暖吧,所幸啥都是可以烧的,除了飞机。他们进入一种魔法冻结的状态,只要不起飞就永远是新的。
子弹火药是不需要的,因为弹药已经纯能化了,属于100%空气榨汁那种。
和装甲部队换防后整整一年,除了被动挖战壕和参谋部每天开会,攒蓝色方案条以外;一条狼穴的命令都没来过。原来元首在北非和英吉利打得火热,毕竟那里是帝国通往石油和工厂的捷径。
据说这里已经被忘记了,领导一眼都没看过,只有每45天来的一车骡子,送来3套可怜的,从远东买来的名字很怪的枪,还有0.5门火炮。这个炮非常有趣,如果在正确的侧面看就是一门炮,但是一旦稍微移动视角,就会发现这门炮没入了虚无,仿佛根本不存在,听说45天后还会送剩下0.5门炮的一半,也就是0.25门炮 … ⌘ Read more

光荣公司的历史观点有什么特色?
光荣的英雄史观到达登峰造极的地步,还是得看杀马特打架的无双系列。《战国无双2》作为十几年前发行的割草动作游戏,其内容之充实,底蕴之丰厚,人物之丰满,讲述之流畅,恐怕只有同属光荣的《真三国无双6》可以比拟。
《战国无双2》的主要武将很少,为了游戏性,很多战役出现人物跨时空乱入的情况,但这某种程度上又给不同故事线的人物互相影响、互相埋设伏笔提供了便利。真田幸村的故事始于长筱之战,历史上这是他父辈还正值壮年时参加的战争。在通说中,长筱一役标志着传统武士道的终结,也是天下人所开创的安土桃山新时代的开端。本作中真田幸村就在这里和武田家一起,作为旧武士走向没落,直到前田庆次突入解救他。之后的故事里,真田幸村就开始了上下求索、找寻属于自己的道路的历程。他结识了石田三成和直江兼续,为了三人共同的理想而奋斗。但结果,三成战死在关原、兼续为了上杉的存续向德川投降,当幸村在大阪城面对全天下的大军,仿佛又回到了长筱,那个他失去一切、新时代开始的地方。只不过这一次,幸村不再迷茫,新的 … ⌘ Read more

历代的《三国志》里有哪些细思恐极的细节?
看了一圈没有说三国志12的,三国志12人气这么低吗?补充几句。
1. 高览在本作是单挑王,战法一开无人能制,不愧是“河北四庭柱”之一。如此看来,设计组应该研究过张国良的《评话三国》 。
(高览武力82,战法降敌方30点武力,也就是说武力112才能打平,可吕布+方天画戟才108,可以想象武力七八十的碰到高览该有多绝望。)
2. 作为吉祥物,刘禅能力值全班倒数第一,看起来这辈子就基本告别战场了。但问题是,他的战法是“全攻城强化”。本作有个设定:系统非常青睐拥有攻城类战法的武将,不但让他们出征,而且是第一顺位。由此,吉祥物摇身一变成为战争狂魔,动辄带着四五千士兵敲人城门。这一点与文明系列的“核平使者甘地”有异曲同工之处,不知道是不是光荣有意为之。说好的“乐不思 … ⌘ Read more
