&lt;p&gt;&lt;a href="https://openai.com/index/codex-for-almost-everything/"&gt;Codex 随着新版本推出了 Computer Use 功能&lt;/a&gt;，但它并没有在 UK 和欧洲地区正式开放。&lt;/p&gt;
&lt;p&gt;具体表现是：打开 Codex 的设置页面，在 &lt;strong&gt;Computer use&lt;/strong&gt; 一栏里会直接显示 &lt;strong&gt;Computer Use plugin unavailable&lt;/strong&gt;，因此无法宣传里直接安装和使用这个插件。&lt;/p&gt;</description></item><item><title>Wicklow</title><link>https://ecwuuuuu.com/photography/wicklow/</link><pubDate>Thu, 26 Feb 2026 16:53:20 +0800</pubDate><guid>https://ecwuuuuu.com/photography/wicklow/</guid><description>&lt;p&gt;I’d never imagined taking one of those pack-up-and-go trips—until it happened. A close friend came to visit me in Ireland, rented a car, and really wanted to drive somewhere a bit farther out. His first proposal was Galway. It’s only about a two-hour drive, but winter weather here is always a gamble, and no one really knows what conditions will be like once you get there. In the end, I suggested hiking in Wicklow Mountains National Park instead.&lt;/p&gt;</description></item><item><title>关于智能体的实验 1.5 - 讨论式多智能体系统</title><link>https://ecwuuuuu.com/post/agentic-academic-literature-understanding-1.5-cn/</link><pubDate>Thu, 29 Jan 2026 22:50:00 +0000</pubDate><guid>https://ecwuuuuu.com/post/agentic-academic-literature-understanding-1.5-cn/</guid><description>&lt;h2 id="tldr"&gt;TL;DR&lt;/h2&gt;
&lt;p&gt;这篇文章关注我在 SciRead 中实现的&amp;quot;讨论式多智能体&amp;quot;。不同于单智能体的线性推理，这个系统让四个具有不同分析视角的&amp;quot;专家&amp;quot;通过&amp;quot;洞察生成 → 提问 → 回答 → 收敛评估 → 共识整合&amp;quot;的循环讨论论文，最终产出显式记录推理过程、标注分歧、量化共识度的报告。我会说明这种设计的动机、其核心架构、以及相比单智能体方案的权衡。&lt;/p&gt;</description></item><item><title>Authentik - OIDC M2M 认证</title><link>https://ecwuuuuu.com/page/gist/authentik-oidc-m2m-authentication/</link><pubDate>Fri, 02 Jan 2026 12:30:00 +0000</pubDate><guid>https://ecwuuuuu.com/page/gist/authentik-oidc-m2m-authentication/</guid><description>&lt;p&gt;FRP 是一款非常流行的反向代理工具，除了常规的密钥认证方式外，FRP &lt;a href="https://gofrp.org/zh-cn/docs/features/common/authentication/"&gt;也支持 OIDC 认证&lt;/a&gt;。&lt;/p&gt;

&lt;h2 id="tldr"&gt;TL;DR&lt;/h2&gt;
&lt;p&gt;本文介绍了三种不同复杂度的智能体系统设计：单体 Agent、ReAct Agent 和协调多智能体系统。每种设计都有其适用场景和优势。&lt;/p&gt;
&lt;/blockquote&gt;
&lt;h2 id="单体-agent-single-agent"&gt;单体 Agent (single-agent)&lt;/h2&gt;
&lt;p&gt;我打算实现的第一个智能体系统是一个单体智能体，直接复刻我之前在 Cherry Studio 中实现的效果：让一个智能体阅读一篇学术文章，并生成一份详细的报告。使用 PydanticAI 实现 Agent 很简单。创建对象时定义好使用的模型，系统提示词和任务指令，调用 &lt;code&gt;run&lt;/code&gt; 方法传入文章内容就可以了：&lt;/p&gt;</description></item><item><title>关于智能体的实验 0 - 学术文献阅读理解</title><link>https://ecwuuuuu.com/post/agentic-academic-literature-understanding-0-cn/</link><pubDate>Wed, 03 Dec 2025 11:11:00 +0800</pubDate><guid>https://ecwuuuuu.com/post/agentic-academic-literature-understanding-0-cn/</guid><description>&lt;blockquote&gt;

&lt;p&gt;Every developer who maintains a blog eventually faces the question: &lt;strong&gt;Should I use an existing theme or build my own?&lt;/strong&gt; For me, this wasn&amp;rsquo;t just about aesthetics - it was about creating the perfect reading experience for both technical tutorials and personal reflections.&lt;/p&gt;
&lt;p&gt;After years of blogging on various platforms and using different Hugo themes, I found myself constantly wanting just one more feature, a slightly different margin, or better typography for code blocks. Rather than continuing to patch someone else&amp;rsquo;s theme, I decided to build &lt;strong&gt;ecwu-theme&lt;/strong&gt; from the ground up.&lt;/p&gt;</description></item><item><title>探索爱尔兰巴士实时交通数据</title><link>https://ecwuuuuu.com/post/ireland-gtfs-api/</link><pubDate>Sun, 24 Aug 2025 12:00:00 +0100</pubDate><guid>https://ecwuuuuu.com/post/ireland-gtfs-api/</guid><description>&lt;p&gt;直到最近才发现&lt;a href="https://www.nationaltransport.ie"&gt;爱尔兰交通管理局&lt;/a&gt;有一个公开的交通数据。之前我是在使用 &lt;a href="https://transitapp.com/"&gt;Transit App&lt;/a&gt; 来查询时刻表和车辆位置（也是才知道 TFI Live 也可以看到很详细的数据），但有时候这些应用并不能完全满足我的需求（可能只是我个人想要更多的数据，但它们本身是相当不错的软件）。&lt;/p&gt;</description></item><item><title>How I Rebuilt a 2018 Project in 2025</title><link>https://ecwuuuuu.com/post/revisit-uiccourse/</link><pubDate>Sat, 05 Jul 2025 14:10:00 +0100</pubDate><guid>https://ecwuuuuu.com/post/revisit-uiccourse/</guid><description>&lt;h2 id="prelude-the-django-and-jquery-days"&gt;Prelude: The Django and jQuery Days&lt;/h2&gt;
&lt;p&gt;In 2018, I was self-studying the Django web framework for a college course. To apply what I was learning, I decided to build a project to solve a real problem: our school&amp;rsquo;s course information system.&lt;/p&gt;
&lt;p&gt;All official course information was contained within a single, large PDF file. And course details contains in more individual handbooks PDF files. Finding a specific course was a time-consuming process that required extensive scrolling and text searches. I believed I could create a more efficient and user-friendly solution.&lt;/p&gt;</description></item><item><title>Cinestill 800T &amp; Expired Kodak Portra 400</title><link>https://ecwuuuuu.com/photography/new-film-stock-new-thoughts/</link><pubDate>Sat, 18 Jan 2025 18:00:00 +0000</pubDate><guid>https://ecwuuuuu.com/photography/new-film-stock-new-thoughts/</guid><description>&lt;p&gt;My New Year trip to Shenzhen was another photography trip. Alongside catching up with friends on a tight schedule, testing my first roll of CineStill 800T became a side mission. I also brought along a roll of expired Kodak Portra 400 and ILFORD HP5 Plus, as they had been sitting in my fridge for quite some time.&lt;/p&gt;
&lt;h2 id="cinestill-800t"&gt;Cinestill 800T&lt;/h2&gt;
&lt;p&gt;The film isn’t a brand-new release; I heard about its big name from lots of film photograph KOLs at least 3 years ago. This film is basically Kodak&amp;rsquo;s Vision 3 5219 (500T) movie film. A distinctive feature of movie film is it comes with a Remjet layer, a black carbon coating designed to prevent light halation. which is a layer of black carbon coating (calls remjet) on the back of the film to prevents light halation. Traditionally, the film with a remjet layer require one extra step during develop process to remove it.&lt;/p&gt;</description></item><item><title>服务器新装 GPU 的容器化配置笔记</title><link>https://ecwuuuuu.com/post/gpu-container-setup-note/</link><pubDate>Sun, 24 Nov 2024 14:54:00 +0000</pubDate><guid>https://ecwuuuuu.com/post/gpu-container-setup-note/</guid><description>&lt;h2 id="前言"&gt;前言&lt;/h2&gt;
&lt;p&gt;最近需要给一台以前配置的 CPU 服务器装上 GPU，这台机器之前已经配置好了存储和基于 Docker 和 JupyterHub 的计算环境。这里就记录一下装上 GPU 后的配置过程。本文只涉及系统和软件层面的调整。也就是新增的显卡已经安装到设备内，且设备已经能够被系统识别。可以通过 &lt;code&gt;lspci | grep &amp;quot;NVIDIA&amp;quot;&lt;/code&gt; 命令查看设备是否被识别。&lt;/p&gt;</description></item><item><title>Guangzhou, Shenzhen, Hong Kong, and Kodak Gold</title><link>https://ecwuuuuu.com/photography/gz-sz-hk-and-kodak-gold/</link><pubDate>Thu, 03 Oct 2024 23:59:00 +0100</pubDate><guid>https://ecwuuuuu.com/photography/gz-sz-hk-and-kodak-gold/</guid><description>&lt;p&gt;After completing my master’s degree following the COVID-19 outbreak, I transitioned into full-time work. Life became busy, and I gradually set aside my film camera. Recently, I purchased Kodak Gold 200 in 120 format—Kodak’s latest film—during a visit to Guangzhou (新丽照相器材商店). I had planned to capture a few moments before leaving China. I took the film along on a three-day trip to Guangzhou, Shenzhen, and Hong Kong. Eventually, I had the film developed at GZNow Lab in Guangzhou.&lt;/p&gt;</description></item><item><title>Authentik 教程系列：服务的迁移</title><link>https://ecwuuuuu.com/post/authentik-tutorial-5-setup-migration/</link><pubDate>Sun, 08 Sep 2024 22:20:00 +0100</pubDate><guid>https://ecwuuuuu.com/post/authentik-tutorial-5-setup-migration/</guid><description>&lt;div

&lt;p&gt;如果应用不支持统一登录，或者应用比较的简单没用用户系统。想要将它们纳入自己的统一登录体系是比较麻烦。这种情况下 Authentik 提供了一种配合反向代理的鉴权方法：Forward Authentication (没找到中文翻译，我觉得可以译作&lt;code&gt;转发验证&lt;/code&gt;)。&lt;/p&gt;</description></item><item><title>Authentik 教程系列：将应用通过 OIDC，SAML，LDAP 协议接入</title><link>https://ecwuuuuu.com/post/authentik-tutorial-3-setup-oidc-saml-ldap/</link><pubDate>Sun, 21 Apr 2024 14:29:00 +0800</pubDate><guid>https://ecwuuuuu.com/post/authentik-tutorial-3-setup-oidc-saml-ldap/</guid><description>&lt;p&gt;搭建了统一登录平台之后，最重要的事情就是将应用接入。Authentik 支持五种协议接入，分别是 &lt;a href="https://en.wikipedia.org/wiki/SAML_2.0"&gt;SAML 2.0&lt;/a&gt;， &lt;a href="https://openid.net/developers/how-connect-works/"&gt;OAuth 2.0/OpenID Connect (OIDC)&lt;/a&gt;， &lt;a href="https://en.wikipedia.org/wiki/Lightweight_Directory_Access_Protocol"&gt;LDAP&lt;/a&gt;， &lt;a href="https://scim.cloud"&gt;SCIM&lt;/a&gt;，和 &lt;a href="https://en.wikipedia.org/wiki/RADIUS"&gt;RADIUS&lt;/a&gt;，其中 OIDC，SAML，和 LDAP 能覆盖我们大多数的接入需求。在这篇文章我将用具体应用示例的方式演示如何将应用接入 Authentik。&lt;/p&gt;</description></item><item><title>Authentik 教程系列：反向代理的配置</title><link>https://ecwuuuuu.com/post/authentik-tutorial-2-setup-reverse-proxy/</link><pubDate>Mon, 08 Apr 2024 19:55:00 +0800</pubDate><guid>https://ecwuuuuu.com/post/authentik-tutorial-2-setup-reverse-proxy/</guid><description>&lt;p&gt;将服务进行反向代理，我们可以配置通过域名来访问 Authentik。因为 Authentik 实现上不会通过配置写死 URL，所以反向代理的配置非常方便。&lt;/p&gt;

&lt;p&gt;A little bit of context&lt;/p&gt;
&lt;p&gt;This is the tutorial material I prepared in fall 2023, for people with basic foundation of machine learning to get hands-on PyTorch quickly.&lt;/p&gt;
&lt;p&gt;My idea behind the whole document is to teach the reader how to do full model training from the ground up and introduce each component alongside the process.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;ul&gt;
&lt;li&gt;PyTorch is an open-source deep learning framework that provides a flexible and dynamic approach to building and training neural networks.&lt;/li&gt;
&lt;li&gt;Its popularity and widespread adoption by the research and industry communities.&lt;/li&gt;
&lt;li&gt;PyTorch is widely known for its ease of use, Pythonic interface, and excellent support for research-oriented tasks.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;A &lt;strong&gt;computational graph&lt;/strong&gt; represents the flow of data through a computational model in the form of a directed acyclic graph (DAG). It serves as a visual representation of the mathematical operations performed on input data to produce the desired output.&lt;/p&gt;</description></item><item><title>Homelab：我的赛博积木 - 展望</title><link>https://ecwuuuuu.com/post/homelab-journey-future/</link><pubDate>Sat, 07 Oct 2023 02:20:00 +0800</pubDate><guid>https://ecwuuuuu.com/post/homelab-journey-future/</guid><description>&lt;p&gt;从“赛博积木”系列第一篇文章到现在，已经过了两年的时间。受自己需求、实际体验后的感受等多重因素的影响。现有的架构和最初的设计已经有了很大的变化。其中最大的变化应该是在 23 年 6 月新组装的个人服务器，直接影响了我许多服务的部署形式。&lt;/p&gt;</description></item><item><title>Homelab：我的赛博积木 - 访问</title><link>https://ecwuuuuu.com/post/homelab-journey-accessing/</link><pubDate>Sat, 25 Feb 2023 02:20:00 +0800</pubDate><guid>https://ecwuuuuu.com/post/homelab-journey-accessing/</guid><description>&lt;p&gt;前面已经介绍了基础设施和已经部署的服务。对于部署在&lt;a href="https://ecwuuuuu.com/post/homelab-journey-internet/"&gt;公网的服务&lt;/a&gt;，访问是方便的。在 Nginx 中通过反向代理将容器服务绑定在域名上，再配上 SSL 证书就可以实现安全方便的服务访问体验。真正让人头疼的是内网服务的访问和访问控制。&lt;/p&gt;</description></item><item><title>使用 input-overlay 工具在 OBS Studio 中展示鼠标和按键操作</title><link>https://ecwuuuuu.com/post/obs-studio-show-keyboard-and-mouse-activity/</link><pubDate>Tue, 31 Jan 2023 00:16:08 +0800</pubDate><guid>https://ecwuuuuu.com/post/obs-studio-show-keyboard-and-mouse-activity/</guid><description>&lt;blockquote&gt;

&lt;h2 id="配置-ssh"&gt;配置 SSH&lt;/h2&gt;
&lt;p&gt;部署了 GitLab 之后，一直在使用 HTTPS，体验不错。但是当时没有将 GitLab 的 SSH 访问成功配置。&lt;/p&gt;
&lt;p&gt;当初的配置尝试过：1. 将 SSH 与服务器的 SSH 的端口共用。 2. 单独设置一个 SSH 端口并暴露出来。我的操作是直接在域名后面加端口号进行访问：&lt;code&gt;git.ecwuuuuu.com:&amp;lt;port&amp;gt;&lt;/code&gt; 但进行 Git 操作都没有成功过。在排查 Log 发现是链接失败后，对域名执行了 nslookup，发现 IP 并不是预期的服务器 IP，这里是因为我使用了 Cloudflare 的解析服务，真实的 IP 被隐藏了。所以操作行不通。&lt;/p&gt;</description></item><item><title>自建 GitLab 踩坑实录</title><link>https://ecwuuuuu.com/post/self-host-gitlab-instance/</link><pubDate>Fri, 06 May 2022 11:45:36 +0800</pubDate><guid>https://ecwuuuuu.com/post/self-host-gitlab-instance/</guid><description>&lt;p&gt;之前自建了一个 Git 服务来托管自己的非公开代码。考虑要轻量，所以选择了 &lt;a href="https://gitea.io/en-us/"&gt;Gitea&lt;/a&gt; 并通过 Docker + Nginx 的方式进行部署。&lt;/p&gt;
&lt;p&gt;前段时间腾讯云免费提供了轻量服务器配置升级的活动，配置提升到了 4 核心 + 4G 内存。机器性能是一个过剩的状态，为了充分利用，所以我考虑将服务从 Gitea 换到 &lt;a href="https://about.gitlab.com/install/"&gt;GitLab&lt;/a&gt;。这里把我的部署过程进行记录。&lt;/p&gt;</description></item><item><title>500 Hours in 307</title><link>https://ecwuuuuu.com/photography/500hrsin307/</link><pubDate>Thu, 07 Apr 2022 16:07:13 +0800</pubDate><guid>https://ecwuuuuu.com/photography/500hrsin307/</guid><description>&lt;p&gt;This work is the final project of the Photography FE (Free Elective) Course.

&lt;p&gt;Recently, I saw a forum thread. A color-blind person is looking for a solution to identifying the color.

&lt;p&gt;In the &lt;a href="https://ecwuuuuu.com/post/nas-ipv6-ddns/"&gt;Synology DDNS Tutorial&lt;/a&gt;, I have a &lt;a href="https://ecwuuuuu.com/post/nas-ipv6-ddns/#a-firewall"&gt;section&lt;/a&gt; on setting up firewall on an ASUS AC68U Router.&lt;/p&gt;
&lt;p&gt;For a recent update on my home network, the Asus router has been replaced with two Linksys WI-FI 6 tri-band mesh routers (two &lt;a href="https://www.linksys.com/hk/whole-home-mesh-wifi/linksys-mx5-velop-ax-whole-home-wifi-6-system/p/p-mx5300/"&gt;MX5300&lt;/a&gt; or it&amp;rsquo;s SKU MX10600-CN)。&lt;/p&gt;
&lt;p&gt;I thought it will be easy to set up since I already have some experience and documentation, but the firewall is not working as intended.&lt;/p&gt;

&lt;p&gt;When creating the theme announced in the post &lt;a href="https://ecwuuuuu.com/post/new-theme-for-blog/"&gt;Switching to a new theme &amp;hellip; I guess&lt;/a&gt;. I set up a new branch in the original &lt;a href="https://github.com/ecwu/ecwu.github.io.source"&gt;source repository&lt;/a&gt; and uses Cloudflare pages to build the previews for the site. This can make sure all the original Github actions for the main site working normally.&lt;/p&gt;
&lt;p&gt;Since the new branch &lt;code&gt;new-theme&lt;/code&gt; was created using attribute &lt;code&gt;--orphan&lt;/code&gt;, it will be impossible to do pull requests to the original default branch &lt;code&gt;master&lt;/code&gt;.

I choose the theme because I appreciate the aesthetic look of the original Tufte $\LaTeX$ template. Using a dedicated area on the right side of the page for sidenotes, supplements images, or thoughts. Diversify the layout of an article, and make the article fun to read.&lt;/p&gt;
&lt;p&gt;A couple of months ago, under my willingness of making enhancements to the theme. And I start to do some research on how other people are doing sidenote on their blog (Like the &lt;a href="https://www.gwern.net/Sidenotes"&gt;great article&lt;/a&gt; by Gwern Branwen). With some &amp;ldquo;deep thinking&amp;rdquo;. I start to realize. Maybe it is not a good idea to use footnotes on the Internet pages.&lt;/p&gt;</description></item><item><title>I am initiating a new domain!</title><link>https://ecwuuuuu.com/post/new-domain/</link><pubDate>Wed, 01 Sep 2021 14:40:01 +0800</pubDate><guid>https://ecwuuuuu.com/post/new-domain/</guid><description>&lt;p&gt;Starting from Aug 11, 2021. I am starting a new domain name for my website.&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;&lt;a href="https://ecwu.xyz"&gt;ecwu.xyz&lt;/a&gt;&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;Personally, the old domain name (ecwuuuuu.com) is good but is it a little bit longer in length and maybe difficult for people to memorize and use. So, I register this domain name to create some convenience for others (but mostly for myself :)).&lt;/p&gt;
&lt;p&gt;Currently, I am don&amp;rsquo;t have a concrete plan for how to utilize these two domains. But I will probably migrate all my info page and service to the new domain. The domain email and blog will still keep in the old one. I will keep thinking about this, and sync the progress on this page in the future.&lt;/p&gt;</description></item><item><title>Drag</title><link>https://ecwuuuuu.com/photography/drag/</link><pubDate>Tue, 20 Jul 2021 13:57:20 +0800</pubDate><guid>https://ecwuuuuu.com/photography/drag/</guid><description>&lt;p&gt;Hang out with friends in Shenzhen.

&lt;p&gt;On the way back home, I saw more breathtaking scenery. And I captured it with my camera.&lt;/p&gt;
&lt;p&gt;The images are shot using a slow shutter speed, and the shape of the objects is dragged by the movement of the cabin. I arrange the image in a linear (both in time and space) manner. Along with intertwined artificial lights, urban buildings, and twilight sky in the frame. I try to create an emotional transition from active to calm with these four images.&lt;/p&gt;</description></item><item><title>Sigmoid or Softmax for Binary Classification</title><link>https://ecwuuuuu.com/post/sigmoid-softmax-binary-class/</link><pubDate>Mon, 07 Jun 2021 13:06:14 +0800</pubDate><guid>https://ecwuuuuu.com/post/sigmoid-softmax-binary-class/</guid><description>&lt;p&gt;Recently, been asked a question on using neural networks for binary classification.&lt;/p&gt;
&lt;blockquote&gt;
&lt;p&gt;The output layer of the network can be &amp;hellip; &lt;strong&gt;One output neuron with sigmoid activation function&lt;/strong&gt; or &lt;strong&gt;Two neurons and then apply a softmax activation function&lt;/strong&gt;. But what is the difference between these two?&lt;/p&gt;
&lt;/blockquote&gt;
&lt;p&gt;Let start with the equations of the two functions.&lt;/p&gt;
&lt;p&gt;Sigmoid Activation Function
$$
S(x) = \frac{1}{ 1+e^{-x}}
$$&lt;/p&gt;
&lt;p&gt;We input the value of the last layer $x$, and we can get a value in the range 0 to 1 as shown in the figure. If the value is greater than 0.5, we consider the model output as one class, or the other class if the value is less than 0.5.

&lt;p&gt;I can’t really remember when and why I start taking photos from the window. Maybe because of the breathtaking scenery, or just some casual shots. But the first one I can find on my Instagram is taken in March 2014.&lt;/p&gt;
&lt;p&gt;Haven’t thought about making it into a series or project since the beginning. But I have shot a lot of these since 2014 and I think it will be interesting to make it into a series.

Terence is not your typical Political Science enthusiast. His expertise extends beyond social sciences into more technical fields, making him quite a unique addition to the academic landscape. Terence has a deep understanding and expertise in statistics. This proficiency has served him well in his research work, allowing him to analyze and interpret complex data with precision and accuracy. His ability to manipulate numbers and draw meaningful insights from raw data is truly commendable. In addition to statistics, Terence possesses significant knowledge in the field of medical imaging. He understands the nuances of this specialized area and can skillfully interpret the information these images provide. This ability adds an interesting dimension to his research capabilities. Terence's intellectual curiosity does not stop there. He has delved into the intricate world of cryptography. His understanding of the complex algorithms and principles behind secure communication is second to none.
