Hope Alibaba's Qwen improves a bit after going closed-source Just stop making those rookie mistakes that wipe out a user's entire OS instance. My whole WSL --ubuntu instance went up in smoke.
Last year I came across FrankenPHP, this performance beast, but the Drupal core team has been tight-lipped about fully supporting it—they didn't even respond positively to the Caddyfile the community wrote. Then I saw a French guy who published a Caddyfile and shared his hands-on experience. I get t…
I just examined the directory structure of develope.wangjueju.cn. This is a very standard and extremely mature Monorepo + Shared Packages multi-sub-site architecture.

Today I chatted with Grok about a technical issue, front-end development. Because the conversation had many turns and the context got long, it started hallucinating. The three images below make it clear. This proves that LLM-based AI has no thoughts, and also no accurate memory—and…

Although our technology is lacking and our AI models and hardware lag far behind foreign giants, our experts are quite good with their mouths, having seized the AI discourse first and forcing the translation of "Token" to be "ciyuan" (word element).

There was a question before: What would a Linux user write on a tombstone? I set myself one: Pid's Off Then I screenshotted it and threw it to Google's Gemini and Musk's xAI Grok for analysis. Although Grok's Musk keeps bragging how awesome it is, it's actually pretty dumb. But their agent des…
The other day I saw a piece of news. Microsoft has patched a registry tweak in Windows 11 that originated from Windows Server 2025's native NVMe support, which bypasses SCSI emulation to access SSDs directly, boosting IOPS by up to 80% and random read/write speeds by 64–89%, though it may cause inst…
GitHub posted that notice with the cover image, and here's my take:1. Microsoft knows OpenAI is unreliable; they can't put all their eggs in one basket.2. Vibe Coding is the biggest token-consuming use case for LLM-based AI. The best vibe coding models right now — Claude Opus 4.6 and OpenAI's Codex …
To avoid being accused of targeting a vendor, I won't name the specific model, but it's one of the best coding models in China — top 3.I asked the AI to configure a service with two ports: 61080 and 68080;It fiddled around and kept finding that the 68080 service port wasn't being listened on.Then I …

今天看了杨振宁一个访谈，觉得挺有趣的，就摘录一下，又找了一点参考资料。 首先一句话杨振宁说，“我一生最大的贡献，是帮助中国人克服了自己觉得不如外国人这个心理。”这是很对的。我们现在这个社会崇洋媚外，它是一种病，是我们这个社会很严重的一种心理残疾。比如上次加州艺术学院的庄小姐不幸被人谋杀，就有人翻她的ins然后又对她后来找了一个中年白男男朋友大肆挞伐和泼脏水。这其实反映的就是一种心理上的自卑，群体性的自卑。 然后我重点喜欢他讲他和李政道的关系这段： 刚刚听到杨振宁说到，他和李振道合作了13年，他在西南联大并不认识李振道，到了美国才有了很好的合作。 1949年开始合作。但是到1962年由于不可调和…

咨询，consulting，是当我们有问题的时候，向他人寻求建议与意见的行动过程，叫做咨询。 咨询顾问，consultant，就是指为别人解决某些问题，提供建议与意见的人，叫做咨询顾问，consultant。-ant这个词缀，在英语里面常常指xxx的人，就是我们顾问的“者”的意思。比如助理，就是协助做事的人，assist是协助，assistant就是助理。所以consultant就是咨询顾问。有时候我们也简称为顾问。比如我说我是一个十九年经验的留学顾问，或者说是一个十九年经验的跨国教育咨询顾问 transnational education consultant，都是可以的。 所以咨询顾问有时…

《羊粪球》序 由于一些暂时不可言说的原因，当然日后如果我这个集子出版了我会在后记里把这个原因写出来，不过估计也可能不写了，我好像从这个秋天开始情绪比较亢奋。此处删除100字。 虽然我也觉得我有大作家的才情，但是我没有大作家的技巧啊。要我写长篇巨著？那恐怕有点太缘木求鱼了。但是这两天放羊确实闲得很，又不幸读到了王小波的《一只特立独行的猪》，感觉有点那种老母羊吃多了玉米粒的感觉，一方面在自己口里咀嚼着回味，一边又总想拉点羊粪蛋出来。 所以那就写吧，那就把这个集子取名叫《羊粪球》吧。 不过读者不要太高兴，我的序当然不能只有这么点。我意想中的序应该写个八万字的，至少也得写个三万字嘛。主要…

发现drupal在文件分享和管理方面肯定是存在一些问题的。 Drupal不是有一个电子书阅读功能嘛，就是pdf电子书在线阅读，可以做一个电子书的在线阅读，这样也还可以获得一些流量的嘛，毕竟咱不也要为了流量嘛。 但是显然nextcloud是一个文档管理和协作的瑞士军刀啊。 而且nextcloud是有很好的客户端可以使用的。感觉真的是一个非常不错的私有云web管理系统。
I was too careless before. Too hasty. Holy crap! For someone who's built websites for so many years, this is just damn unprofessional.

It hasn't auto-rebooted for three days now. In the previous post I mentioned the auto-reboot problem of the virtual FreeNAS and the server on ESXi.

The four hard drives are passed through to FreeNAS via a SATA HBA adapter card.

感觉passthrough硬盘对于esxi来说并不是一种好的实践。 或许NAS该从esxi里面独立出来。 现在觉得还是直接上硬件，增加硬件性能吧，堆硬件，反正只要不涉及AI计算或者图形计算的，硬件也不会太贵了 特别想固态硬盘
我不觉得自己配置裸机的文件服务器是一个好的实践。 仅此而已。 所以，其实对于一般中小企业而言，如果你想有一个稳定网络服务系统，首先配置一个优秀的高性能的NAS，然后，再镜像它，最好是镜像服务器和这个生产NAS之间能够实现10G光纤连接。 然后，就是，NAS通过nfs，smba （cifs）等协议，给服务器共享空间。 通过软raid可以实现多硬盘高性能高稳定的存储，其实，如果做了mirror服务器的话，我觉得raid最好就用raid0了。高性能。 华硕推出的那个4条NVME固态的raid卡，也是raid 0的，达到超级高的iops性能。 2025增补 之前deepseek之所以出色的降低了对算力…

rocket.chat 是一款非常不错的内部交流工具，当然，它也能配置成开放的社区形式。 但是我觉得它更加适合做企业内部的沟通工具。 之前华为说要启用自己的内部通信工具，不用微信做工作方面的安排，这是有道理的。 而作为一款专为工作通讯而设计的开源工具，rocket.chat的开源基础版本已经可以取代slack了。 而且，自己架设公司内部的通讯工具，通过自己控制的私有云服务器系统，有个好处，就是数据都在自己手里，只要做好内网的安全配置和对于各种爬虫的反爬配置，就可以防止数据的泄露。 -------------- 现在觉得这些都不重要了 25年增评

关于HHVM和php到底谁更强的争论就尘埃落定了。 赢家当然是php 7 然后现在的主线php 7.3 版本，性能是很强的了。 所以，对你的php app进行性能升级，首先就是，升级到php 7.3（现在的主线稳定版本）。 据说facebook转向了hack，我不知道他们是不是要造一个更快的车轮出来，就像他们造了HHVM这个车轮一样。 不过，车轮多一点，大家竞速一下也是好的。 但是，php 7暂时还是web应用服务器里面的赢家。 年轻人，赶紧学PHP
0. Update to the latest PHP 7.3—at the time I wrote this note, that was 7.3.10. 1. Install and enable OPcache. 2. Install and enable APCu. Right now, I feel upgrading the version is a pretty good way to optimize performance. But the key is whether your own program code supports the new version.

云计算确实很好。 但是公有云计算很贵。 这个，你看看亚马逊aws和阿里云还有微软azure的营收就知道了。 而且，海外的云呢，经常访问是很慢的，这个是没有办法的了，而且我相信在未来一段时间，会越来越慢。你看看，用composer或者git下载一个包，都不知道要等多久，如果你的服务器在国内的话。 而且，云计算供应商都很鬼的，虽然有无限容量，但是，流量收费贵啊，带宽贵啊，实际上按流量收费这种生意，和卖白粉差不多赚了。 其次，容量无限啊，带宽无限啊，内存贵啊。 内存你还付得起的，反正配置费用主要就是内存费用嘛。但是，iops贵啊。 阿里云就有一个，iops随着购买的云盘容量增长的计算公式。所以，你如…
But later they used SaaS subscriptions to scoop up the whole open-source project and its community in one go. Actually, one should be wary of open-source communities. I recall that back then the SugarCRM 7.0 Community Edition was long delayed in release, while SugarCRM itself became a SaaS platform,…
并不是一项新的技术了。 记得好几年之前就有欧洲的通信公司提供了这样的技术给某个石油生产大国，实现了基于数据包的拆包审核与重新打包发送，也就是审核通过的数据包，就继续传递，审核发现含有不合规内容的数据包，那么，这个通信就被截断了。 所以，基于IP和tcp端口层面的所有技术，也就没有什么意义了。 好有一比，有些人想通过虹吸作用，从一个地方把水吸到另外一个地方去。但是很可惜的是，你的水管本身是带滤网功能的，遇到泥沙和颗粒的触发，它就把这个水管直接关闭或者把这部分水给你抽掉从另外的一个口子漏掉了。这样，确保你的水管流出来的是纯净的干净的无害的水。 普天之水，都需要水管才能送到家，水管滤网技术谁家强？ …

As I've said, tinkering with this and that on the Snail Star's native motherboard and chip is truly like putting on a show inside a snail's shell — making a big fuss in a tiny, cramped space. Think about it: the J1900 has glaring limitations — it supports at most 8 GB of RAM. Even just as a NAS, hon…
有天我想，如果把编辑器直接放到了前端，那不就和微博或者facebook或者linkedin的status发布页面一样方便了吗？ drupal有个发行版本social做到了那样，但是它把activities都弄进来了，做得比较复杂了。我用了它几次，关键的是它经常升级出错，卸载模组出错，我被搞的实在太烦了，所以就放弃了。 然后我想，我不就是只是需要一个status log的内容类型（content type）和一个在前端某个位置可以用的编辑器区块（block）吗？ 当然，开始我想到了是把blog和status分开，status用评论系统（comments）来实现，这个想法非常自然，因为评论的编辑器…
具体的解释我就不多说了 反正我都是follow别人的教程 所以，直接连接教程就好了 https://www.linuxtechi.com/install-kvm-hypervisor-on-centos-7-and-rhel-7/ --------------------------------------------------------- 下面是一些啰嗦而已 对于教程，这些英文源的工具（就是说来自歪果仁做的开源的工具的，比如，centos，linux），我一般都是直接看英文的。很少用中文的教程，倒不是有些中文教程不好，尽管大部分中文的教程都是听垃圾的，很多也是机器爬取了英文的教程然后直接…

安装的时候选择的安装内容为虚拟化服务器但是没有UI 然后，安装完之后，重启，拔掉安装介质U盘，进bios设置系统盘启动。 不见屏幕显示任何内容，但是网卡不停的闪烁。 我操作了一会鼠标和键盘，可以响应热键重启，所以，猜想是不是没有装UI它就没有这个显示器的驱动，只是启动了一个没有显示界面的系统。然后，用ssh通过另外一台机子登录，果然是这样。 yeh！ 上次我找这个工控板的开发商，说，你们板子有问题啊，我装ubuntu没问题，但是装centos启动它是黑屏的。看来是错怪了他们。 娃哈哈！ 明天起来给他们售后工程师去说一下这个事情，道个歉。
Just follow this tutorial. https://www.howtoforge.com/tutorial/how-to-upgrade-kernel-in-centos-7-server/
Multilingual Drupal and automatic translation still have quite a few problems, but they're basically usable now. So let's just use it. I never expected a perfect CMS anyway, and as a personal blogging platform, it's good enough.
Publish a long post if you want to publish a long post. And I've made it possible to publish articles right from the homepage. So what's the difference compared to Weibo? At least in terms of usability, there's no real difference either. It's just exposing a content input form to a frontend block. B…
Although earlier, for some inexplicable reason, I forgot to renew the database subscription, which caused a stretch of newly published posts to be lost. This won't happen again. Even if the server lapses, it just becomes inaccessible — but the database lives in my own private-cloud cluster, so unles…
I'm truly glad to be able to use this technology to publish my little records and thoughts to the world. True, the machine-translated foreign languages aren't always precise, but I believe that for native speakers of those languages, getting the gist of what I mean is (if we don't demand word-for-wo…
终于把我的surface book给修好了，自己拆机，自己换电池，自己装回去。 再换电池重新启动看到屏幕背板上四个孔闪出了光亮之后，我就在心里喊了一声，稳了！ 然后再小心翼翼地把屏幕转过来，看到了熟悉的深蓝大海开机界面，我就恨不得把还在睡觉的孩子们喊起来和我一起分享这个喜悦！
Only after using Microsoft's OneDrive did I realize what a load of crap so-called cloud computing is. File sync is dead slow. With a few more files it's a joke — it can freeze the folder browser and leave the whole computer unresponsive. Whoever designed this garbage.
今天又到了六一节了，作为两个儿子的父亲，当然是要写点东西的，虽然儿子们现在还读不懂，但是，还是要写出来，留待日后。 儿子们，我想对你们说，除了你，这个世界一无所有。因为，你就是度量这个世界的尺度。这个世界的好，这个世界的坏，这个世界的美，这个世界的丑，都只有你能够感知，你能够判断，当然，你也能够创造。 在未有人类之前，世界就傻啦吧唧的存在了好多亿年了，大概有40多亿年了吧，但是，直到有了人类，世界才有了度量。至于某些宗教人士说的那些虚无缥缈无法证实的神迹与神话，我们就当它是原始人类一种无知的妄想吧，毕竟，他们的逻辑本身也很混乱，他们的说辞，本身也经不起推敲，当然…
在CN要冲百万的时候，好像没人管什么CN注册的问题。 在央视吹口水的时候，又要企业才能注册了。那在一元时代注册那么多CN域名的站长怎么办呢？ 所以，我看了一下CNNIC的缩写，应该是可以扩展成：Center of Noreason Net Information Control这样的名字了。中国无厘头网络内容控制中心。 附：CNNIC关于进一步加强域名注册信息审核工作的公告 为了提升域名注册信息的真实性、准确性、完整性，进一步加强域名注册信息审核工作，现通知如下要求： 所以，我看了一下CNNIC的缩写，应该是可以扩展成：Center of Nore…

《我看中国大学的教育现状》在华尔街日报中文版网站被刊发之后，也引起了不少的评论，它在本博上原来是针对华尔街日报中文版的一篇文章《中国大学扩招易 学生就业难》而作的一个短评。这我我再把它和它在华尔街日报中文版网站上获得的评论一起整理出来，当做一个存档吧。特别是WSJ经常被墙的情况下。 2014年5月1日：华尔街日报中文网这篇文章的链接得翻墙才能看到了。真是让我很高兴呀。 五年前的文章了，可是，现在的状况有什么改善么？没有，中国经济的兴奋剂依赖症，不是还在么？调控调控，调了几届了，还是走老路来的舒服。引鸩止渴，爽且速衰呀。经济结构调整不力，高知就业就是狗屁呗。创业也舍不得促进，贷款贷…
php文件要求使用 FTP 软件上传 php 文件时，使用二进制（BINARY）方式进行，否则将无法正常使用(安装时,出现页面空白的现象)。 所有的 FTP 服务器端和客户端软件均支持两种方式的文件上传，其一为文本（ASCII）上传，其二为二进制（BINARY）上传。PHP要求用户在上传 PHP 程序文件时，使用二进制的上传方式进行。原因为某些程序文件经过编译处理，使用一般的文本上传会造成文件传输错误，影响您的使用。您可以在所有的 FTP 客户端软件中找到有关二进制上传的选项，例如 LeapFTP， CuteFTP 等。以下举例说明这两种客户端软件设置 PHP 文件二进制上传的方…
现在各大学都流行网上申请，online application. 但是有些学校的网申服务器访问起来却非常的慢（如果你是教育网用户访问起来慢应该是正常的，因为据说有些学校如果要开通国外访问是要另外花钱买代理的）。 今天要拿来批斗一番的是两个学校的网申服务器，Boston University （boston 大学）和University of Arizona（亚利桑那大学）。即使我用电信（注意，电信是中国出国海缆带宽拥有量最大的运营商）的ADSL访问，打开这两家的网申网站仍然像蜗牛一般慢。这不，我这篇牢骚文都写完了，刚刚完成一个登录过程，有时候它干脆给你来个空白页面，NNGX。我觉得肯定这两间学…
