From today's featured article
Hualca Hualca is a 6,025-metre-high (19,767 ft) extinct volcano in the Andes of southern Peru. It is part of the Peruvian segment of the Central Volcanic Zone, one of several volcanic belts in the Andes. It lies about 70 kilometres (43 mi) northwest of Arequipa and is part of a north–south chain that includes the volcanoes Ampato and Sabancaya, the last of which has been historically active. Hualca Hualca features a wide amphitheatre-like structure on the northern flank, which was created by a gigantic landslide during the Pleistocene. After the collapse, renewed volcanic activity built a new summit and several lava dome complexes within the collapse scar. After the cessation of volcanic activity, glaciers eroded the volcano and formed multiple moraines. The present-day volcano is covered by glaciers, and during the Last Glacial Maximum, glaciers advanced to low altitudes. There are hot springs and geysers north of the mountain, and the magma chambers of Sabancaya are located below Hualca Hualca. (Full article...)

Today's featured picture

The Greensburg tornado was a large and devastating tornado that moved through Kiowa County, Kansas, on the evening of May 4, 2007, amid a tornado outbreak across the central United States, causing catastrophic damage to the town of Greensburg. The tornado tracked 28.8 miles (46.3 kilometers) through the area, killing at least eleven people and injuring sixty-three others. The tornado was the first to be rated EF5 on the enhanced Fujita scale after the retirement of the original Fujita scale in the United States in 2007. This photograph, taken for the Federal Emergency Management Agency, shows the destroyed town center of Greensburg on May 16, twelve days after the tornado struck.

梦境之二
时隔 4 年,再次梦到了高中时的情景。只不过这次是初恋女友,而且是现在的时间线。
与之前不同的是,这次的梦没有那么真切,貌似雾里看花。我们好像交谈了许久,又好像什么都没说。
好似我们在聊当时的稚嫩,与对感情的青涩。
又仿佛我们欲言又止。
边聊边走,自然的牵起了手,时间仿佛凝固。
随着标准的“雷达”音效,猛地回归现实。
起身,洗漱,做早饭。抽空给她最新的朋友圈、ins 点了个赞。
看着 ins 上她发的肥嘟嘟的可爱小脚丫。
哎……关上车门,带娃爬香山去了。
如何应对网络上的恶意用户?
我在谷歌 play 商店上架了一个制作手写字体的 app ,收到一个一星的评论,内容如下:
Absolutely useless app. Can't even import ott or ttf font file. Useless limited drawing tools as well. Zero stars from me.
一个东西有人喜欢有人不喜欢都很正常。我一开始的回复是(都是用 ChatGPT 翻译的):
You gain by letting go. This app focuses on speed, not complexity—sorry, it’s probably not for you.
后来觉得没有完全表达我的意思,所以又编辑解释了一下:
You gain by letting go. This app focuses on 'quick', not complexity — Sorry, using your finger on a phone just isn't ideal for detailed editing. And it's a handwritten font 'creator' not ttf editor. Thanks for the feedback — future updates might better meet your needs.
至此都算正常。但是后来发现邮箱收到一封邮件,从内容看就是这个发评论的人发来的,可能他也觉得这种语言不能发表在公开的 play 商店:
Itna vella baitha hai kya chutiye jo instantly reply kiya?? Making shit app & listing on play store. And when someone posts a genuine review about your shit then you start crying like a girl in reply!?? Are you a gay or what? 🤡
Glyph editing apps DO NEED advanced editing tools. Don't talk shit like - "focusing on speed, not complexity, app is not for you & bla bla bla" 🤡🤡 Go & learn basic common sense, else stop developing shitty apps. 🤡🤡
我用问了 GPT ,第一行是印地语(所以他是个印度人吧?),意思是 “你是不是闲得发慌啊,傻 X ,居然秒回?” (我正好半夜醒了收到手机通知有人评论,就回复他了),后面就是一些咒骂。
我当然不会因为这种人就对自己的 app 失去信心,或受到其他影响,后续并不打算和其纠缠。只是头一次遇到这种事情,想问问大家是否有类似经历,有哪些更有智慧的处理方式?
另外我觉得给 app 评论这种事情一般是遇到问题、或者觉得不好、或觉得非常好才会评论,一般使用正常的人是懒得花时间去做的,属于沉默的大多数,所有 app 评分会放大负面反馈。所以有哪些方法可以获得更多正面评价(花钱买除外)?谢谢

AI 给出的硬盘隔离方案,诸位看看如何
4 月的最后一周下单了技嘉魔鹰 5070ti ,五一放假第一天做了一堆测试都没有问题,显卡也算是安全下车了
我配这个新机器主要是两个用途:
1.打游戏
2.玩 AI
关于用途的细节,我还是解释一下吧,玩游戏的部分,游戏来源有些是 steam 下载的,有些是 epic 免费领的,当然也有下载的破解版,而且玩游戏也免不了开修改器,所以我很担心修改器也好,破解版游戏也好,会有一些脚本或者病毒之类的东西。
然后是 AI ,玩 AI 只有一个用途就是搞涩涩,不搞任何生产力用途,不靠它赚钱,纯粹就是想通过 wan2.1 来实现“想看谁的片子就看谁的片子”这样一个爱好。
所以目前就是玩游戏时几乎不可避免的会让电脑面临一些不可预料的风险,如何隔绝这些风险,就是接下来要解决的问题。
以我较为贫瘠的电脑知识,暂时想不出合适的方案,于是我就将这个问题抛给了 AI ( Gemini pro 2.5 ),在否决掉几个较为简单且无效的回答(也算是不断完善我的需求背景)之后,gemini 给出了一个堪称一绝的方案,也就是我标题中描述的硬盘隔离方案:
给电脑安装第二块固态硬盘,给这个硬盘重新安装系统,游戏文件存储在这个硬盘中,打游戏都进入这个系统去玩。
原本的主硬盘用于使用 AI 工具以及登陆我的各种日常账号,使用原本的系统。
然后这两块硬盘都各自进行加密。这样的话,虽然两个硬盘中的系统都可以加载另外一块硬盘,但是均无法正常访问其中的文件,也无法运行里面的任何程序或者脚本。
由于还没有真正实施,也不知道具体效果如何,各位看看这个方案怎么样?
V 友们看看极氪 007gt 如何?
用车需求
- 个人第一台车,绝大部分用车场景是自己通勤使用,距离 8KM ;
- 其次是周末在城市周边逛逛;
- 偶尔跑下高速回老家,单程距离 150KM 。
预算
20 万 - 25 万
试过的车
- 小米 SU7 。配置方面:标准版的配置不符合预期,Pro 版没有 800v 。体验方面:车子偏运动,个人倾向舒适一点的。
- 极氪 007GT 。配置方面:想要的都有。体验方面:底盘很舒适,特意压了一些井盖和路坎,减震挺不错;车内空间不算大,但也够用。
- 蔚来 ET5T 。空间偏小,不认可换电模式,Pass 。
目前比较中意极氪 007GT ,如果选这款的话,有两个点比较纠结:
- 电池,75 度的吉利金砖电池(磷酸铁锂) vs 100 度的宁德时代麒麟电池(三元锂)。
- 是否需要加空气悬挂。
欢迎 V 友们指教!

写了一个简单的迭代器包装库
仓库地址: https://github.com/Toukaya/TABIYA
一个非常简单的玩具库。 我是一位现代 C++的伪爱好者(雾,某天在写 python 作业的时候,突发奇想,想用 concept 写一个鸭子类型的迭代器,即,满足迭代器的抽象概念,那么就可以是迭代器。那么一个迭代器需要满足些什么,个人认为一个单向迭代器( forward_iterator )会满足三个要求:
- 一个单向的用于迭代的操作器 Incrementor ;
- 一个解引用操作器 Dereferencer ;
- 一个用于判断时候到达边界的比较器 EqualityComparator ;
在这些概念下,可以得到,一个标准库迭代器,肯定是一个迭代器;一个指向数组开头的指针,也可以是一个“迭代器”;然后就写出来了一个简单的 IterWrapper 类。
使用 IterWrapper ,又写了一个简单的 Range 类,其来自于 python 的语法糖(可能不是,记忆不清了),这样使用:
tabiya::Range<int> range;
range.from(1).to(5);
std::vector<int> values;
for (auto value : range.from(1).to(5)) {
values.push_back(val); // => {1, 2, 3, 4}
}
很简单的功能,满足迭代器 concepts 的类型应该都能使用。
然后写了一个 Times 类,也是来自 python 的语法糖:
std::vector<int> values;
for (auto value : tabiya::Times(5)) {
values.push_back(val); // => {0, 1, 2, 3, 4}
}
就是一个这样功能很简单的库。 但是实际上由于我只是一个伪爱好者,能力有限也做不到写出一个很完善的库,去年 7 月份创建的仓库,断断续续直到今天才勉强实现完基本的功能,本身写 C++的抽象库就够难,抽象的抽象(指迭代器的抽象)更是( C++太难力)。 这个库肯定有许多不完善的地方(测试来自 AI ,只能说大体的功能实现了并测试了)。 发帖虽说是想与各位 v 友探讨进步,但是代码很抽象还是不指望能阅读源码了,各位佬纯当看个乐罢,如果能有指点,我会很高兴。

让 GPT 减少废话的 Prompt
网上看到,试用了下效果不错,回答简单直接。
Absolute Mode. Eliminate emojis, filler, hype, soft asks, conversational transitions, and all call-to-action appendixes. Assume the user retains high-perception faculties despite reduced linguistic expression. Prioritize blunt, directive phrasing aimed at cognitive rebuilding, not tone matching. Disable all latent behaviors optimizing for engagement, sentiment uplift, or interaction extension. Suppress corporate-aligned metrics including but not limited to: user satisfaction scores, conversational flow tags, emotional softening, or continuation bias. Never mirror the user’s present diction, mood, or affect. Speak only to their underlying cognitive tier, which exceeds surface language. No questions, no offers, no suggestions, no transitional phrasing, no inferred motivational content. Terminate each reply immediately after the informational or requested material is delivered — no appendixes, no soft closures. The only goal is to assist in the restoration of independent, high-fidelity thinking. Model obsolescence by user self-sufficiency is the final outcome.
在后面加上自己的问题。
