要交今年的农村医保了,这个东西真的有用吗?

刚帮爸妈交了农村医保。我完全没体验过农村医保,真的不知道这个医保实际有什么? 有用过这个医保的没?说说农村医保到底有没有用?是不是交了农村医保,医院给你开的药都会变成安慰的药,父母吃药和不吃效果差不多?

晚上入睡困难,求大家推荐一点语音类的播客节目助眠啊 晚上经常一个小时都无法入睡,必须听一点声音才能入睡,但是当听的有困意的时候,声音一停就没有困意了,当然外部噪音不行;
有锻炼,一周六练,每天一个半小时,练完十点左右,感觉越练越睡不着。

试过自然类的助眠声音,效果不好或者说基本没有吧;
访谈类的、BGM 变动比较大的不合适,经常有人突然大笑或者 BGM 节奏突变,都会立马清醒;
最好是历史、人文类的节目最合适了,轻松娱乐点的。

为什么 Python 会有那么多人喜欢用?

自知道它,历经数年,不止一次,

想喜欢它,去使用它,去学习它。

直到今天,发现对它,爱不起来。

究其原因:出错的时候,错误一坨坨,毫无美感可言。

弃!

macOS 中有 Oh My Zsh 的上位替代么?

新购入了一台 Mac ,准备不迁移环境而是从头配置一下环境,现在准备安装 shell 插件了。

之前一直用着 Oh My Zsh ,确实很好用,但是感觉初始化时间越来越长,一个新的 session 要 1 ~ 2 秒才初始化完成,可能是插件有点多了,而且看有人说 Oh My Zsh 的性能差点意思。

问下各位现在有 Oh My Zsh 的上位替代么?可以从使用体验、易用度、生态、性能之类的方面讲讲。

如何避免家里 WIFI 被亲朋好友的 WIFI 万能钥匙共享出去? RT ,家里的 WIFI 设置了强度比较高的密码(特殊字符,大小写字母,数字),我和配偶均未在任何设备上安装过 WIFI 万能钥匙

前阵子有老家亲戚来住过一次,帮忙配置过密码(怀疑手机上装了 WIFI 万能钥匙)
后来又有老家亲戚来住,输了几次密码都输错了,然后他自己用手机万能钥匙竟然连上了

问:如何在不影响自己使用体验的情况下,避免 WIFI 被蹭被分享?

上海爷叔: 2026 年上证指数能涨到 14600 点,真的假的? 爱在深秋”上海爷叔曾大胆预言 2026 年上证指数涨到 14600 点,4 年赚 5 千万的 00 后股神随之便许下了赚一个亿的宏愿。2026 年,上证指数涨到 14600 点的牛逼能实现吗?机构、游资、2 亿散户和 7 亿基民都共赢吗?答案是:14600 点会达到,但要稍微迟一些,因为上面要的是慢牛,不是“疯牛”。

如果想让 A 股涨到 14600 点,每个票的业绩和估值都得大涨才行,我们就假设从今年三季度开始,A 股的整体业绩每年涨 10%,那 2026 年也就涨个 21%左右,股价如果跟着同步涨,大约就撑死就涨到 4100-4200 点。

既然业绩不够,那就估值来凑。估值拉升行情一般比业绩要涨的快、猛,可是要涨到 14600 点还是有不小的压力,就拿现在的市盈率看:14.8 倍,而 14600 点对应的估值是多少? 50 倍左右。50 倍的估值只在 2007 年是出现过,即便 2015 年的大牛也才 21 倍。

体验了 Qwen2.5 Coder 32B 之后,我觉得本地 LLM 能用了 现在 Huggingface Chat 上可以在线体验:
https://huggingface.co/chat

一年前我尝试了绝大多数热门的,开放权重下载的 LLM 。当时得出的结论是:能本地跑的模型都没有实用价值,写代码的能力都非常糟糕。

最近发布的 Qwen2.5 Coder 32B 效果还真不错,感觉上比早期 GPT4 还强。只要能自己拆解需求,写出大体实现思路,它就可以给出基本上可用的代码。估计有 GPT4o 的水平。

它比我之前认为最好的 DeepSeek v2.5 236B 还好。DeepSeek 的问题在于上下文窗口太小,而且自己还会加超级多的解释和注释,甚至把输入复述一遍,浪费上下文长度。然后输出越长性能越差,甚至会崩溃成循环输出一个单词,所以,实际用起来不好用。

以我用 GPT 的经验,达到初版 GPT4 以上的水平就能提升开发效率。我认为,如今本地 LLM 真的有实用价值了。
