<content type="html"><![CDATA[<p>之前看到有網站的游標長得像這樣，就一直很想用。這次花了些時間研究給弄好了。<br><img src="/img/circle_cursor/cursor.png" alt="游標"></p><p>這個原理其實很簡單，用兩個 div，<code>border-radius: 50%;</code> 呈現圓形。CSS 套用樣式，JavaScript 讓他跟隨滑鼠就完成。</p><p>在程式和樣式部分我參考了這個：</p><div class="container"><p class="codepen object" data-height="300" data-default-tab="js,result" data-slug-hash="zYdmvJE" data-pen-title="Circle Follow Cursor" data-editable="true" data-user="Hakadao" style="height: 300px; box-sizing: border-box; display: flex; align-items: center; justify-content: center; border: 2px solid; margin: 1em 0; padding: 1em;"><span>See the Pen <a href="https://codepen.io/Hakadao/pen/zYdmvJE">Circle Follow Cursor</a> by Hakadao (<a href="https://codepen.io/Hakadao">@Hakadao</a>)on <a href="https://codepen.io">CodePen</a>.</span></p><script async src="https://public.codepenassets.com/embed/index.js"></script></div><p>這是我修改後的程式與樣式，讓他更搭配我的主題，也另外增加了一些顏色與形狀的變化：</p><figure

<content type="html"><![CDATA[<h1 id="前言">前言</h1><p>前幾天正覺得 Windows 10 電腦卡頓，想到一段時間沒有關機了，於是心血來潮將筆電重新啟動。但是電腦卻一直無重新啟動，我只好直接強制關機再開機。沒想到開機登入後一直卡在歡迎的畫面轉圈圈，而這一轉就是一小時。以下是我嘗試的一些方法。</p><h1 id="方法">方法</h1><ol><li><p>重新啟動<br>完全沒用，開機後還是卡在歡迎畫面。</p></li><li><p>直接放著讓他跑<br>應該沒用，嘗試放了一個小時還在歡迎轉圈圈，受不了就關掉了。不知道放更久會不會就進去了。</p></li><li><p>用安全模式登入<br>完全沒用，安全模式登入只要等五分鐘即可進入系統，與一小時相比迅速非常多，不過還是很慢。且使用安全模式進去後再重新用正常模式依然無法登入。</p></li><li><p>禁用硬碟<br>完全沒用，我的筆電有三顆硬碟，我在 BIOS 中將兩顆硬碟禁用，只保留一顆系統碟。依然無法登入。</p></li><li><p>使用其他帳號登入<br>有一點用，正好我的筆電有兩個帳號，另一個帳號十分快速就登入了。但當我要使用我主要的帳號授權管理員權限給第二個帳號時，輸入密碼後依然卡住。到這裡我覺得是軟體的問題，尤其是我主要的帳號。</p></li><li><p>回到還原點<br>有一點用，回到還原點和重設是不一樣的。重設是將電腦的設定與軟體回復預設狀態，還原點則是將設定與軟體回到幾天前的狀態。沒想到回到還原點後再讓他在歡迎跑約二十分鐘就可以登入了！！這時候我會趕緊使用 Windows 的修復指令來嘗試修復電腦：</p> <figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line">DISM.exe /Online /Cleanup-image /Restorehealth</span><br><span class="line">sfc /scannow</span><br></pre></td></tr></table></figure><p>詳細的可以參考這篇：<br><a href="https://support.microsoft.com/zh-tw/topic/%E4%BD%BF%E7%94%A8%E7%B3%BB%E7%B5%B1%E6%AA%94%E6%A1%88%E6%AA%A2%E6%9F%A5%E7%A8%8B%E5%BC%8F%E5%B7%A5%E5%85%B7%E4%BE%86%E4%BF%AE%E5%BE%A9%E9%81%BA%E5%A4%B1%E6%88%96%E6%90%8D%E6%AF%80%E7%9A%84%E7%B3%BB%E7%B5%B1%E6%AA%94%E6%A1%88-79aa86cb-ca52-166a-92a3-966e85d4094e">https://support.microsoft.com/zh-tw/topic/使用系統檔案檢查程式工具來修復遺失或損毀的系統檔案-79aa86cb-ca52-166a-92a3-966e85d4094e</a></p><p>這樣就修好了，但這只是治標不治本。我發現有時我直接<strong>重新啟動</strong>就會出問題，我必須要<strong>關機</strong>再<strong>開機</strong>。就算我都先關機再開機，過不了三四天又會在歡迎卡住。</p></li><li><p>升級 Windows 11<br>我認為會卡在歡迎是軟體的問題，說不定升級系統可以把壞掉的文件洗掉，因此我開始嘗試升級 Windows 11。幸運的是，我的電腦符合規格，不用另外做其他事情就能升級。不幸的是，不知道出了甚麼問題，再升級時一樣遇到了卡死的問題。我使用了各種方法皆是如此：</p><ul><li>Windows Update：卡在 96%</li><li>Windows 11 安裝小幫手：卡在 99%</li><li>Windwos 11 安裝程式：卡在 90%</li></ul><p>只剩製作開機隨身碟升級的這個方法沒有試，但以上三個方法每個都等了六個小時以上，再等下去會影響到我的事情，因此沒有繼續升級。</p></li></ol><h1 id="結論">結論</h1><p>目前已第六個方法效果最為顯著，但我並不認為這個問題就此解決了，這依舊只是一個暫時性的解決方案。如果有任何建議或想法，歡迎留言討論，我需要你的幫助。</p>]]></content>

<title>在 Windows 上安裝 AdGuard Home 並用於路由器 (超簡單教學)</title>

<content type="html"><![CDATA[<p>這次的教學是如何在家中的 Windows 電腦上安裝 <a href="https://adguard.com/zh_tw/adguard-home/overview.html">AdGuard Home</a> 作為路由器的 DNS 伺服器讓全家人免受各種廣告的干擾。</p><h1 id="前言">前言</h1><h2 id="什麼是-DNS？">什麼是 DNS？</h2><p>DNS(Domain Name System)，中文為網域名稱系統，提供域名解析的服務。在網路世界，每台電腦都有它自己的地址，也就是 IP。我們使用瀏覽器上網時，就像我們的電腦去指定的地址拿取其他電腦中的資料，也就是電腦向伺服器 IP 發起請求。但平時瀏覽 Google、Youtube 或者和泉小角落時我們都沒有輸入 IP，都是輸入網址，電腦怎麼知道去哪裡找資料呢？實際上電腦就是用網址取得 IP 的！！在一般常見的網址中包含網站的域名，電腦會透過我們輸入的網址得知欲前往之網站的域名，再詢問 DNS 伺服器這個域名對應的 IP。因此，IP 作為地址，域名就像是地址的名字。例如我今天想瀏覽小明的網站，我先在瀏覽器輸入小明的電腦(域名)，我的電腦轉而向 DNS 伺服器詢問小明的電腦的地址(IP)，得知地址後我的電腦再訪問該地址，成功瀏覽小明的網站！！</p><p>DNS 伺服器有很多，速度、功能以及安全性皆有所差異。</p><h2 id="什麼是-AdGuard-Home">什麼是 AdGuard Home</h2><p>AdGuard 最著名的功能就是擋廣告，許多人都會再瀏覽器上安裝其插件。而 AdGuard Home 是 AdGuard 推出的開源 DNS 伺服器，內含許多阻擋廣告的功能。相比其他 DNS 服務，雖然有些皆有阻擋廣告的功能，但自己架設的 DNS 伺服器可以客製化調整，架設在自己家也較安心。</p><h3 id="AdGuard-Home-如何阻擋廣告">AdGuard Home 如何阻擋廣告</h3><p>AdGuard Home 使用 DNS Sinkhole 的方法來阻擋廣告，這種方法會對特定的域名給出錯誤的結果。假設我今天想要瀏覽小明的網站，但是 DNS 故意回報我錯誤的地址，就會導致小明的網站無法正常顯示。這一樣適用於廣告！！當電腦向廣告的域名發送請求時，DNS故意回報 <code>0.0.0.0</code> 給電腦，導致請求失敗，就無法顯示廣告了。</p><p>但是像 Youtube 這種影片中的影片較難阻檔，若要阻擋這類廣告推薦安裝<a href="https://chromewebstore.google.com/detail/adguard-%E5%BB%A3%E5%91%8A%E5%B0%81%E9%8E%96%E5%99%A8/bgnkhhnnamicmpeenaelnjfhikgbkllg">插件</a>解決。</p><h1 id="教學">教學</h1><p>正式進入教學啦！</p><h2

而得到諾貝爾物理學獎的天野浩教授演講。中午時會和學伴一起吃午餐，印象中我的學伴叫做 Sho Ota さん。他因為忘記帶名牌掛繩所以用充電線綁在脖子上代替，是個十分有個性的人。他們的便當幾乎都是自己在家準備好帶來的，雖然份量小但看上去十分美味。</p><p>午餐後由另一位學伴帶我參觀校園以及觀賞海報展覽，學伴叫做一翔さん。我們互相介紹時十分驚喜，Kazuto 和 Kayato，我們的名字只差一個字！！後來在參觀海報展覽時，遇到的日本同學都很友善。我很驚訝ももなさん第二次看見我時還記得我的名字，令我十分開心。之後又遇到 Yoshito さん等人，是十分有趣、不怕生的一群人，也很愛起鬨。最後我們一起拍了 JOJO 立的照片，<s>看起來就像一群人中二病發作wwww</s>。</p><p>在 Sho Ota さん的班上玩了一些團康遊戲後就到社團參觀，我去的是茶道部。我們被帶進一間鋪上塌塌米的茶室，品嘗和菓子和茶。我第一次知道原來走路時踩塌塌米之間的邊緣是禁忌，好像是邊緣上常有許多家紋或動植物的圖案，如果踩在上面就等於踐踏祖先或動植物。坐定後有許多穿和服的人走進來為我們送和菓子和茶，和菓子有一點點甜，茶不錯喝。他們對於喝茶的方法十分講究，印象中要左手拿碗，右手扶著，接著順時針轉動茶碗再喝，避免從茶碗的正面喝茶，然後必須分二到三口將茶全部喝完。</p><p>再送茶的期間亭主擔心大家腳酸，一直提醒大家不必跪坐，可以照自己舒服的方式坐。不習慣跪坐的話要維持姿勢確實會有點吃力。＞﹏＜</p><p>整趟旅程最有趣的活動莫過於參訪岡崎高中，和許多同年的外國學生互動的機會是十分難得的。<br>由於被日方通知隨意在網路上散播學生的照片會有法律問題，因此這裡就不放照片了。原本想放大門但忘記拍了。╯︿╰</p><h3

<content type="html"><![CDATA[<h1 id="The-traditions-of-Tao">The traditions of Tao</h1><p>We all know that sumo wrestlers only wear a length of cloth on their crotch, but do you know why Tao’s men also wear like that?<br>Before we talk about this question, let’s learn more about Tao. The Tao people, also known as the Yami people, are the only aboriginal ethnic group in Taiwan whose main traditional settlements are located on the outlying islands of Taiwan. They have a marine culture, with great ritual and spiritual significance placed on boat-building and fishing. When it comes to Tao, we must talk about tatala. Tatalas are extremely important instruments on living and traditional events for Tao people. They are made of several boards, smaller Tatalas are made of 21 boards while bigger ones need 27 boards. Every Tatala has a totem in the shape of an eye on their bow and stern. It is believed that it can guide the boat in the sea and disperse disasters.<br>Apart from the Tatalas, Tao’s clothes also have some totems. The traditional clothing of Tao’s women would include a shawl, a short skirt and a rope. On the shawl were stripes in black, blue and white, it was called nyozitan na ayob. The Taos think the nyozitan na ayob could protect their souls and ward off evils. Tao men’s clothing is very different from women’s, they wear a vest with blue and white color and a length of cloth on their crotch. The reason why they wear this way is because of the job they do. Most of the Tao’s men are fishermen who have to work on the sea under scorching sun lights. If they wear too much, water will soak their pants and let them get heavier, the hot and humid weather will also discomfort them. So it is necessary for them to wear less.<br>Besides the aforementioned traditions, there are still a lot of things that we haven’t talked about like the underground house or myths and legends. Undoubtedly, all of the traditions of Tao are indispensable and precious for Taiwan.</p><h1 id="Reference">Reference</h1><p>[1]維基百科（2024）。<em>達悟族</em>。取自 <a href="https://zh.wikipedia.org/zh-tw/%E9%81%94%E6%82%9F%E6%97%8F">https://zh.wikipedia.org/zh-tw/達悟族</a><br>[2]蘭嶼．人之島（2023）。<em>達悟的拼板舟</em>。取自 <a href="https://travel.lanyu.info/tao-culture/%E9%81%94%E6%82%9F%E7%9A%84%E6%8B%BC%E6%9D%BF%E8%88%9F">https://travel.lanyu.info/tao-culture/達悟的拼板舟</a><br>[3]張靈、那牧特、蕭祺等（2015）。Ayob no tao 最好的衣服。<em>952 vazay tamo 第三期</em>。</p>]]></content>
