<title>【筆記】APCS 2022 年 6 月場</title>
<url>/APCS-2022-01/</url>
<content><![CDATA[<p>這是我第一次去考 APCS（誰叫你之前都忘記報），當天考觀念時肚子真的痛得要命，直到中午才去宣洩…我的考場在台北大學三峽校區，令我意外的是男女比沒有到很重，但是大佬倒是挺多的。考實作題時，不知道是不是緊張，就是一直在 debug…最後是寫到第三題寫了一點就結束了。我那天超孤單😢，我朋友給我請假…說他抽考沒讀，我也沒讀啊🤬。反正最後考了 4 / 3 還蠻理想的。</p>
<h2 id="數字遊戲易"><a class="markdownIt-Anchor" href="#數字遊戲易"></a> 數字遊戲（易）</h2>
<p>ZJ 連結：<span class="exturl" data-url="aHR0cHM6Ly96ZXJvanVkZ2UudHcvU2hvd1Byb2JsZW0/cHJvYmxlbWlkPWkzOTk=">https://zerojudge.tw/ShowProblem?problemid=i399<i class="fa fa-external-link-alt"></i></span></p>
<p>輸入：3 個 1 ~ 9 的數字</p>
<p>輸出：先輸出數值出現最多的次數，再輸出三個數，且去除重複，由大到小。</p>
<p>想法：既要去掉重複又要排序，我的第一想法就是使用 set。set 是一個容器，它具有資料的唯一性，也就是不可重複，且容器內也會排序，跟 map 一樣。第一筆輸出我會用 4 - set 長度，這樣恰好是重複的個數，再用反向迭代器輸出 set 容器即可。</p>

<title>【心得】少有人走的路：心智成熟的旅程</title>
<url>/The-Road-Less-Traveled/</url>
<content><![CDATA[<p>這本書在講的是自律、愛、心智成長、信仰、恩典等各個問題。主要在於心智的成長</p>
<h3 id="自律"><a class="markdownIt-Anchor" href="#自律"></a> 自律</h3>
<p>作者要求我們要做到 推遲滿足感、承擔責任、忠於事實、保持平衡 並細心理解其中道理。</p>
<p>我們其實早已得知何為推遲滿足感，又或稱延遲享受。最早可推至小時候，那時的我們總能聽到大人說：「去寫完功課再去玩手機」「完成家事後，才能看電視」「被完單字才能睡覺」這都是先苦後樂的道理，而自律就是基於這個道理去執行的。我很常聽到：「要怎麼自律？」其實我也不清楚，我只知道，自律使人充滿幹勁，他會義無反顧的完成他的任務。自從我有了平板、手機的四年級起，我就開始每天玩著諸如此類的 3C 產品，甚至連電視也不跟爸媽搶著看了。說實話，這樣的行為，早已打破了自律。自律是從小就該培養的東西，而父母正是傳遞自律的途徑。在出生不到一歲嬰兒的意識裡，不存在爸媽的形象，只知道這兩個人會不斷的出現在自己眼中，然後供給自己生活所需。因此父母是我們一生的依賴，我們從小就在他們身上學到所有行為，包含吵架方式、打掃方式、溝通方式等處理事務的能力。所以自律也不例外，它是需要被培養的，它能使我們面對問題。</p>
<blockquote>
<p>解決人生問題的首要方案，乃是自律，缺少了這一環，你不可能解決任何麻煩和困難。局部的自律只能解決局部的問題，完整的自律才能解決所有的問題。<br />
《少有人走的路》Page 18</p>
</blockquote>
<p>而它關聯性較強的無非是爸媽的愛，爸媽的愛告訴我們：有他們在，我可以不怕前方恐懼，進而得到勇氣，因為我們知道我們是被愛的，所以不怕被拋棄、遺棄，充滿著安全感。這安全感能讓我們面對問題、正視問題。</p>
<p>倘若沒有了愛，那我們面對世界會變得恐懼、不敢面對，導致常常逃避問題，把問題把在一旁，時常提醒自己要解決它，但都是以不想弄、懶得弄、今天好累不想做、之後有時間再弄作為結尾。</p>
<blockquote>
<p>美國開國先哲本傑明．富蘭克林說過：「惟有痛苦才會帶來教益。」面對問題，聰明者不因害怕痛苦而選擇逃避，而是迎上前去，直至將其戰勝為止。<br />
《少有人走的路》Page 19</p>
</blockquote>
<p>作者還提到人生的意義是甚麼，也正如他所說：許多人應該都答不太出來。或許人生的意義就是遇到問題，然後解決問題，再遇到新的問題，繼續解決它，反覆無常，使我們意識裡得到了許多感悟並從問題中成長，或許這就是人生的意義吧。</p>
<p>而作者特別將沒辦法自律多推究給父母親。通常爸媽面對孩子的不斷詢問後的反應總是不耐煩的說：「你再吵，我就不要你了」這種威脅會不斷出現在孩子的回憶裡，不斷重演，也包括我的過去，爸媽的責怪、罵聲，總能讓我重回當下的陰影裡揮之不去。但幸虧於那些慘不忍睹的記憶，我告誡自己：我不要成為和自己父母一樣的大人。至此之後，我總是一個人在房間度過自己和自己相處的時光，作業、課本似乎一動也沒動，因為我腦中出現太多畫面，根本沒有機會去想我還有甚麼事情沒做，就算想起自己還有一堆課業要顧，但每每還是沒辦法有那動力去學習，不斷的困住自己。</p>
<blockquote>
<p>父母同樣是指揮官，其使命和管理企業一樣複雜。正像軍隊指揮官那樣，大多數父母面對孩子的問題束手無策，連續數月乃至數年都無任何舉措，只可一味拖延。<br />
《少有人走的路》Page 37</p>
</blockquote>
<p>我不怪罪於父母，他們的養育我感恩在心。若父母都不自律，我為甚麼還要與父母親計較，我若有能力自律，我大可不必大吵一架之後，委屈自己還打破家庭的平靜，說實話我不知道甚麼是錯甚麼是對，所謂的叛逆又是什麼，是我們的頂嘴還是與大人之間的爭吵，難道大人都是對的，我們都是錯的，或許並非如此。所以我再次告訴自己：要學會與自己和解，才能與家人和解，到現在我仍過意不去，明明是因為幫你抬瓶汽水，我覺得重所以才嘆口氣，你卻要說我：「你這甚麼態度！」現在才覺得我父親挺可笑的…未釐清事實真相，就血口噴人，我為何要受這委屈呢？我當時若有我現在的想法那有多好啊！我多恨我父親啊！所以即使爸媽沒有自律，我也要變的自律，才有辦法洗掉那些慘痛的經歷。這不是說大話，這位心理學作者接觸過的病人，即變成年了，也沒有能力自律，我同意它所說的。</p>
<p>所以作者希望我們能學會的四個要素</p>
<ol>
<li>推遲滿足感</li>
<li>承擔責任</li>
<li>忠於事實</li>
<li>保持平衡</li>
</ol>
<p>我也大都能理解了。</p>

<title>【經驗】逢甲資工系 APCS 組面試經驗</title>
<url>/FCU-CSIE-APCS-interview/</url>
<content><![CDATA[<h1 id="前言"><a class="markdownIt-Anchor" href="#前言"></a> 前言</h1>
<p>其實面試不用緊張，照你們平常跟老師的講話方式就好。目前我面的學校，教授們都很 Nice，我本人就慢熟，但我的高中有模擬面試，有模擬面試就去試試看，體驗一下那種感覺，然後說實話不用太壓抑自己，把想說的說出來即可，教授特喜歡這種有想法的人。</p>
<span id="more"></span>
<h1 id="面試過程"><a class="markdownIt-Anchor" href="#面試過程"></a> 面試過程</h1>
<p>以下是大致過程，可能有漏問題，但是應該不會影響到整體面試內容。</p>
<p>三對一個人面試，從左至右，教授編號為（A）到（C）用英文字母表示表示</p>
<hr />
<ol>
<li>B 教授：請自我介紹 1 分鐘（自介後就輕鬆聊）</li>
</ol>
<hr />
<ol start="2">
<li>B 教授：我從學習歷程問我你有一點很特別，就是可以選了一個 C 語言，你可以說一下為什麼選擇 C 嗎？</li>
</ol>
<ul>
<li>我：因為 APCS 的觀念題是用 C 語言，我希望可以藉由多元選修來增強 APCS 的觀念題。</li>
<li>B 教授：那有沒有覺得 C 比較難寫？</li>
<li>我：有，但主要是 C 跟 C++ 的寫法都蠻像的，只差在輸出寫法不同。</li>
<li>全部：然後就大家就 Blablabla 嘻嘻哈哈</li>
</ul>
<hr />
<ol start="3">
<li>C 教授：可以說明一下工程應用這門課在幹嘛嗎？</li>
</ol>
<ul>
<li>我：（我沒聽清楚）可以請教授在問一次問題嗎</li>
<li>C 教授：就是你有一個工程課在幹嘛，因為你拿了 99 分，可以說明一下嗎？</li>
<li>我：（前面有點吱吱嗚嗚然後才想到 -_-）喔！在那門課主要是在畫草圖，學習如何建模，然後</li>
<li>A or B 教授：那是用什麼軟體呢？</li>
<li>我：是用網頁上的 Onshape</li>
<li>教授：嗯~（各教授點頭）</li>
</ul>
<hr />
<ol start="4">
<li>B 教授：從這邊的資料，我看到你都是填 APCS 組想元智、淡江等等，想問你如果都上的話你會想進哪間？</li>
</ol>
<ul>
<li>我：我會選擇逢甲，因為在 SITCON 計算機年會中，我有看到逢甲學長在上面演講，也想加入逢甲的黑客社學習以及交流技術。</li>
<li>B 教授：那那入取你的時候，其他的學校就不用考慮了</li>
<li>教授：依舊嘻嘻哈哈</li>
</ul>
<hr />
<ol start="5">
<li>A 教授：那你有什麼想問的問題嗎？</li>
</ol>
<ul>
<li>我：因為我希望可以成為網頁工程師，目前只接觸過 HTML、CSS 和 JavaScript，想問教授我可以往哪個方面學習？</li>
<li>A 教授：其實如果會寫網頁的話，就要注意資安，要確保你的網頁是沒有漏洞的，BlaBlaBla</li>
<li>C 教授：還要看你的網頁的內容阿，架構阿等等等，BlaBlaBla。</li>
</ul>
<hr />
<ol start="6">
<li>A 教授：那還有什麼問題嗎？</li>
</ol>
<ul>
<li>我：嗯…沒有了</li>
<li>B 教授：好，那就到這邊吧，可以請同學出去了。</li>
<li>我：嗯好，謝謝教授們。（走出會議廳點頭示意並關門）</li>
</ul>

<title>作者使用的 C++ 編譯器</title>
<url>/cpp-compiler/</url>
<content><![CDATA[<h2 id="線上"><a class="markdownIt-Anchor" href="#線上"></a> 線上</h2>
<ol>
<li><span class="exturl" data-url="aHR0cHM6Ly9yZXBsaXQuY29tL34=">Repl.it<i class="fa fa-external-link-alt"></i></span><br />
<strong>優點</strong>：線上編譯，可以在不同地方不同電腦上寫 code ，可隨時新增不同程式語言的專案。打好的 code 可以直接複製網址給其他人（放心，其他人更改不了你的 code ）。<br />
<strong>缺點</strong>：帳號的存放大小有限，不過對方變性就已經不錯了。以及部分功能需付費。<em>雖不用按下你的 ctrl + s ，但是如果網站剛好卡住就沒辦法隨時存檔。 （作者曾經歷過…）</em></li>
</ol>
<h2 id="應用程式"><a class="markdownIt-Anchor" href="#應用程式"></a> 應用程式</h2>
<ol>
<li>
<p><span class="exturl" data-url="aHR0cHM6Ly9jb2RlLnZpc3VhbHN0dWRpby5jb20v">Visual Studio Code<i class="fa fa-external-link-alt"></i></span><br />
<strong>優點</strong>：可自行下載延伸模組，自由度較高<br />
<strong>缺點</strong>：也許是作者還不夠理解，新手可能對這個有點難因為還有環境的配置，作者的同學也編譯不了 C++，不過作者本人有成功，但就是在這上面研究許久…</p>
</li>
<li>
<p><span class="exturl" data-url="aHR0cHM6Ly9zb3VyY2Vmb3JnZS5uZXQvcHJvamVjdHMvbWluZ3ctdzY0L2ZpbGVzL21pbmd3LXc2NC9taW5ndy13NjQtcmVsZWFzZS8=">MinGW<i class="fa fa-external-link-alt"></i></span><br />
<strong>特點</strong>：提供一個可執行 gcc 程式開發環境，整合了許多 windows 下可運行的標頭檔案和檔案庫，為 c++ 的開發提供了良好基礎支援，他不是一種編輯器，是一個提供環境做編譯的程式，非常重要。</p>
</li>
<li>
<p><span class="exturl" data-url="aHR0cHM6Ly9zb3VyY2Vmb3JnZS5uZXQvcHJvamVjdHMvb3J3ZWxsZGV2Y3BwLw==">Dev-C++<i class="fa fa-external-link-alt"></i></span><br />
<strong>特點</strong>：使用 MinGW32/gcc 編譯器，可高亮度語法顯示，以減少編輯錯誤。</p>
</li>
<li>
<p><span class="exturl" data-url="aHR0cHM6Ly93d3cuY29kZWJsb2Nrcy5vcmcvZG93bmxvYWRzL2JpbmFyaWVzLw==">Code Blocks<i class="fa fa-external-link-alt"></i></span><br />
<strong>特點</strong>：也是使用 MinGW 做編譯的，擴充性強大，也適合開發應用程式。</p>
</li>
</ol>
<h2 id="結語"><a class="markdownIt-Anchor" href="#結語"></a> 結語</h2>
<p>作者目前使用的是 <span class="exturl" data-url="aHR0cDovL1JlcGwuaXQ=">Repl.it<i class="fa fa-external-link-alt"></i></span> 和 VScode，其他編輯器我也只有在學校電腦上使用，所以還不知道他們的特性。線上的編譯器和延伸模組多到用不完的編輯器真的很好用，包括我撰寫的這篇文章也是用 VScode 編輯出來的，他的延伸模組之後也會出一篇來推薦幾個好用的，提供大家使用。</p>

<title>【教學】EP 2 - Discord.py 之 Cog 篇</title>
<url>/discord-bot-02/</url>
<content><![CDATA[<div class="note info"><p>在閱讀此篇文章前，作者建議：您已有程式的基礎底子，並且此篇著重於程式碼的部分，其餘皆為概略步驟。</p>
</div>
<div class="note warning"><p>請注意文章日期的時效性</p>
</div>
<h2 id="為何要使用-cog-寫法"><a class="markdownIt-Anchor" href="#為何要使用-cog-寫法"></a> 為何要使用 Cog 寫法</h2>
<p>在使用這種寫法前，我是既不熟悉 Python 語法，以及其特色（其實是忘記了），所以好一段時間放棄了用 Python 寫。但現在稍微略懂之後，才發現這種寫法有很多好處：</p>
<ol>
<li>好維護</li>
<li>事件函式與前綴指令不會衝突</li>
<li>前綴指令不用一直重新啟動 Bot</li>
<li>指令可分類</li>
</ol>
<p>總之，其實只需要修改幾行程式碼，就可以讓你的整體結構更清晰易懂，還不快點使用這種寫法。你可以在 <span class="exturl" data-url="aHR0cHM6Ly9kaXNjb3JkcHkucmVhZHRoZWRvY3MuaW8vZW4vc3RhYmxlL2V4dC9jb21tYW5kcy9jb2dzLmh0bWw=">discord.py Cogs 官方文檔<i class="fa fa-external-link-alt"></i></span> 中找到更多詳細解說。</p>
<span id="more"></span>
<h2 id="cog-架構"><a class="markdownIt-Anchor" href="#cog-架構"></a> Cog 架構</h2>
<p>請將你的檔案目錄修改成如下：</p>
<figure class="highlight txt"><table><tr><td class="code"><pre><span class="line">DiscordBot</span><br><span class="line">| bot.py</span><br><span class="line">|</span><br><span class="line">└─cogs</span><br><span class="line"> event.py</span><br><span class="line"> main.py</span><br></pre></td></tr></table></figure>
<p>也就是請在主目錄下，創建一個 <code>cogs</code> 資料夾，以及在其之中分別創建 <code>event.py</code> 及 <code>main.py</code>。</p>
<ul>
<li><code>main.py</code>：主要在寫你的前綴指令（或是斜線指令）</li>
<li><code>event.py</code>：主要在寫事件觸發函式</li>
</ul>
<p>等等，已經有指令、有事件偵測了，那 <code>bot.py</code> 要幹嘛？</p>
<ul>
<li><code>bot.py</code>：主要提供 load、unload、reload 的指令，可以讓 Bot 不掉線，也能修改程式，並讓 Bot 收到最新的指令。</li>
</ul>
<h2 id="cog-實作"><a class="markdownIt-Anchor" href="#cog-實作"></a> Cog 實作</h2>
<h3 id="bot-檔內容"><a class="markdownIt-Anchor" href="#bot-檔內容"></a> Bot 檔內容</h3>
<div class="note warning no-icon"><p>💡小技巧：可以使用 <code>前綴指令+help</code> 來查看可使用的指令</p>
</div>
<h4 id="load-載入"><a class="markdownIt-Anchor" href="#load-載入"></a> Load 載入</h4>
<p>用於將新的程式檔案載入，或是之前未載入的檔案載入。</p>
<figure class="highlight py"><table><tr><td class="code"><pre><span class="line"><span class="meta">@bot.command()</span></span><br><span class="line"><span class="keyword">async</span> <span class="keyword">def</span> <span class="title function_">load</span>(<span class="params">ctx, extension</span>):</span><br><span class="line"> <span class="keyword">await</span> bot.load_extension(<span class="string">f"cogs.<span class="subst">{extension}</span>"</span>)</span><br><span class="line"> <span class="keyword">await</span> ctx.send(<span class="string">f"Loaded <span class="subst">{extension}</span> done."</span>)</span><br></pre></td></tr></table></figure>
<h4 id="unload-卸載"><a class="markdownIt-Anchor" href="#unload-卸載"></a> Unload 卸載</h4>
<p>用於若程式碼有問題，可以先卸載避免機器人出錯</p>
<figure class="highlight py"><table><tr><td class="code"><pre><span class="line"><span class="meta">@bot.command()</span></span><br><span class="line"><span class="keyword">async</span> <span class="keyword">def</span> <span class="title function_">unload</span>(<span class="params">ctx, extension</span>):</span><br><span class="line"> <span class="keyword">await</span> bot.unload_extension(<span class="string">f"cogs.<span class="subst">{extension}</span>"</span>)</span><br><span class="line"> <span class="keyword">await</span> ctx.send(<span class="string">f"UnLoaded <span class="subst">{extension}</span> done."</span>)</span><br></pre></td></tr></table></figure>

<title>【教學】EP 1 - 用 Python 架自己的 Discord Bot 吧</title>
<url>/discord-bot-01/</url>
<content><![CDATA[<div class="note info"><p>在閱讀此篇文章前，作者建議：您已有程式的基礎底子，並且此篇著重於程式碼的部分，其餘皆為概略步驟。</p>
</div>
<div class="note warning"><p>請注意文章日期的時效性</p>
</div>
<h2 id="為何自架"><a class="markdownIt-Anchor" href="#為何自架"></a> 為何自架？</h2>
<ol>
<li>因為興趣（？</li>
<li>市面上太多太多需要付費使用的 Discord Bot</li>
<li>自架的可調性高</li>
<li>可以順便當作自己的小作品</li>
</ol>
<h2 id="從何開始"><a class="markdownIt-Anchor" href="#從何開始"></a> 從何開始？</h2>
<p>這邊建議尋找 YouTube 影片學著做或其他文章。</p>
<h3 id="安裝-python"><a class="markdownIt-Anchor" href="#安裝-python"></a> 安裝 Python</h3>
<ol>
<li>你得先安裝好 <span class="exturl" data-url="aHR0cHM6Ly93d3cucHl0aG9uLm9yZy9kb3dubG9hZHMv">Python<i class="fa fa-external-link-alt"></i></span> 的環境，安裝時，記得 PyPI 也要勾選到，它可以提供許多 Python 實用的套件。</li>
<li>安裝完後，請先新建一份資料夾，這個就是你的專案，我命名：<code>DiscordBot</code>。</li>
</ol>
<h3 id="安裝-visual-studio-code"><a class="markdownIt-Anchor" href="#安裝-visual-studio-code"></a> 安裝 Visual Studio Code</h3>
<p>這是一個文字編輯器，用來編輯檔案。也可以使用其他文字編輯器，但我推薦使用 VS Code。</p>
<ol>
<li>安裝後，請在 Marketplace（延伸模組）中，再搜尋：<span class="exturl" data-url="aHR0cHM6Ly9tYXJrZXRwbGFjZS52aXN1YWxzdHVkaW8uY29tL2l0ZW1zP2l0ZW1OYW1lPW1zLXB5dGhvbi5weXRob24=">Python<i class="fa fa-external-link-alt"></i></span> 和其他你想裝的延伸模組。</li>
</ol>
<h2 id="建立自己的機器人"><a class="markdownIt-Anchor" href="#建立自己的機器人"></a> 建立自己的機器人</h2>
<ol>
<li>請到 <span class="exturl" data-url="aHR0cHM6Ly9kaXNjb3JkLmNvbS9kZXZlbG9wZXJzL2FwcGxpY2F0aW9ucw==">Discord Developer Portal<i class="fa fa-external-link-alt"></i></span> 建立機器人，也就是按下【New Application】。</li>
<li>接著你可以開始先對它做基本的修飾：Name（剛才命名過了）、Description、App Icon（就是頭像）</li>
<li>在左側導覽列進入【Bot】，找尋細項：【TOKEN】，並把它複製起來（記著它）。</li>
</ol>
<div class="note warning"><p>請勿把機器人的 TOKEN 洩漏在其他地方，例如：你可能會想部署到你的 GitHub Repo，或者其他地方。<br />
因為當你洩漏了，其他人就有可能操控它。</p>
<p>當然，你也可以試看看會發生什麼事（其實就只是 DC 會通知你 TOKEN 外洩，請重新生成一個 TOKEN）</p>
</div>
<ol>
<li>接著在左側導覽列進入【OAuth2】，找尋：【OAuth2 URL Generator】，勾選【SCOPES】中的 bot 和【BOT PERMISSIONS】中的 Administrator。</li>
<li>接著進入下方所生成的連結，邀請到你的伺服器就可以看到你的機器人已加入你的伺服器啦！</li>
</ol>
<h2 id="開始寫自己的機器人吧"><a class="markdownIt-Anchor" href="#開始寫自己的機器人吧"></a> 開始寫自己的機器人吧</h2>

<p>先在終端機安裝 Python 的 <span class="exturl" data-url="aHR0cDovL0Rpc2NvcmQucHk=">Discord.py<i class="fa fa-external-link-alt"></i></span> 套件，輸入：<code>pip install discord.py</code></p>

</li>
<li>
<p>存好檔後，就可以執行它啦。可以測試在頻道打出 Hello，它就會回應你 Hello, world!</p>
</li>
</ol>
<p>這部分是透過事件偵測，來觸發機器人的回應。如果要讓機器人使用前綴指令，可以參考下方程式碼。</p>
<figure class="highlight py"><table><tr><td class="code"><pre><span class="line"><span class="comment"># 導入 Discord.py 模組</span></span><br><span class="line"><span class="keyword">import</span> discord</span><br><span class="line"><span class="comment"># 導入 commands 指令模組</span></span><br><span class="line"><span class="keyword">from</span> discord.ext <span class="keyword">import</span> commands</span><br><span class="line"></span><br><span class="line"><span class="comment"># intents是要求機器人的權限</span></span><br><span class="line">intents = discord.Intents.<span class="built_in">all</span>()</span><br><span class="line">bot = commands.Bot(command_prefix = <span class="string">"="</span>, intents = intents)</span><br><span class="line"></span><br><span class="line"><span class="meta">@bot.event</span></span><br><span class="line"><span class="comment"># 當機器人完成啟動</span></span><br><span class="line"><span class="keyword">async</span> <span class="keyword">def</span> <span class="title function_">on_ready</span>():</span><br><span class="line"> <span class="built_in">print</span>(<span class="string">f"目前登入身份 --> <span class="subst">{bot.user}</span>"</span>)</span><br><span class="line"></span><br><span class="line"><span class="meta">@bot.command()</span></span><br><span class="line"><span class="comment"># 輸入 $Hello 呼叫指令</span></span><br><span class="line"><span class="keyword">async</span> <span class="keyword">def</span> <span class="title function_">Hello</span>(<span class="params">ctx</span>):</span><br><span class="line"> <span class="comment"># 回覆 Hello, world!</span></span><br><span class="line"> <span class="keyword">await</span> ctx.send(<span class="string">"Hello, world!"</span>)</span><br><span class="line"></span><br><span class="line">bot.run(<span class="string">"機器人的TOKEN"</span>)</span><br></pre></td></tr></table></figure>
<p>接著試著打 <code>$Hello</code>，它就會回應 Hello, world!</p>
<p>但如果你想讓這兩段程式碼合併，你會發現它無法正常執行，這是因為 on_message 與 command 相互牴觸，所以之後將再額外講解 Cog 寫法，它可以有效的解決前綴指令與事件觸發的牴觸問題，並且在維護上將會變得更容易維護。</p>

<title>【筆記】前序式、中序式與後序式</title>
<url>/infix-postfix/</url>
<content><![CDATA[<h2 id="電腦怎麼進行四則運算"><a class="markdownIt-Anchor" href="#電腦怎麼進行四則運算"></a> 電腦怎麼進行四則運算？</h2>
<p>電腦其實很笨，所以計算機在做運算時，只會依你的命令順序做運算。</p>
<p>比如題目為 3 + 2 * 4</p>
<p>若照著順序按，得到的答案是 20。但以四則運算來說這很明顯已經錯了，答案應該為 11。</p>
<p>那前中後序的差別就是運算子的先後順序，可電腦有更好的方法進行四則運算，那就是後（前）序式。</p>
<p>後序式如：3 2 4 * +</p>
<p>數字在前，而運算子在後。在中序轉後序時，運算子會在過程中有比對先後順序，而非直接把運算式按順序放置後方。</p>
<figure class="highlight text"><table><tr><td class="code"><pre><span class="line">運算子 數字 數字 // 前序</span><br><span class="line">數字 運算子 數字 // 中序</span><br><span class="line">數字 數字 運算子 // 後序</span><br></pre></td></tr></table></figure>
<p>所以如果要讓電腦看得懂四則運算的規則必須要讓電腦知道每個符號的有先順序<br />
如：<br />
<code>*</code> <code>/</code> 大於 <code>+</code> <code>-</code><br />
<code>(</code> <code>)</code> 大於 <code>*</code> <code>/</code></p>
<h2 id="中序式轉後序式"><a class="markdownIt-Anchor" href="#中序式轉後序式"></a> 中序式轉後序式</h2>
<p>若遇到數字則直接輸出或放入字串，遇到運算子就判斷後放進 stack 裡。<br />
若 <code>stack.top()</code> 的運算子權重小於讀取的運算子，如：<code>+</code> <code>-</code> 小於 <code>*</code> <code>/</code> 直接 <code>stack.push(運算子)</code>，<br />
若 <code>stack.top()</code> 的運算子權重大於讀取的運算子，如：<code>*</code> <code>/</code> 大於 <code>+</code> <code>-</code> 則先輸出或放入字串 <code>stack.top()</code>，再 <code>stack.pop()</code>，最後才 <code>stack.push(運算子)</code>。<br />
若符號是 <code>(</code> 則直接放入，繼續進行程式直到遇到 <code>)</code>，才把 stack 到 <code>(</code> 裡的符號輸出或放入字串，記得最後也要把 <code>(</code> pop 掉。</p>

<p>沒錯！它是一個可以幫你快速搭建部落格網頁的工具。</p>
<h2 id="什麼是-github"><a class="markdownIt-Anchor" href="#什麼是-github"></a> 什麼是 GitHub？</h2>
<p>GitHub 是一個商業網站，是目前全球最大的 Git Server。你可以在上面分享你的程式碼、結交相同志趣的朋友、貢獻自己的程式碼將一個專案做的越來越好。當然別人也可以給你回饋，有如一個程式碼的社群，而且上面的環境很乾淨。<br />
同時，這個網站也是開發者最好的履歷，因為做過的專案、寫過的 code、做了什麼貢獻、有什麼勳章，都可以一目瞭然。</p>
<p>Git 與 GitHub 差別在哪？</p>
<p>Git 是工具，GitHub 是網站。<br />
Git 是一個版本控制系統，簡單來說就是一個可以把檔案的狀態作為更新歷史記錄保存起來，<br />
而 GitHub 就是一個提供 Git Server 的網站平台。</p>
<p>所以現在就來用 Hexo 做做看自己的網站吧！</p>
<h2 id="創建-github-帳號-設置專案"><a class="markdownIt-Anchor" href="#創建-github-帳號-設置專案"></a> 創建 GitHub 帳號 + 設置專案</h2>
<p>進入 <span class="exturl" data-url="aHR0cHM6Ly9naXRodWIuY29tLw==">GitHub 官網<i class="fa fa-external-link-alt"></i></span> 後，註冊 <code>Sign up</code> 並登入 <code>Sign in</code><br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/image.png" alt="" /></p>
<p>進到 GitHub 首頁應該長這樣<br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/github-homepage.png" alt="" /></p>
<p>右上角有個加號點下去之後，選擇 <code>New repository</code>，進入後的畫面如下<br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/new_repo.png" alt="" /></p>
<p>於 <code>Repository name</code> 那一欄填上 <code>使用者名稱.github.io</code>。忘記使用者名稱的話，其實就在左側一欄。<br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/new-repository.png" alt="" /></p>
<p>接著就按下綠色的創建鍵 <code>Create repository</code> 即可。</p>
<p>進入專案後，點擊 <code>setting</code> 選項。<br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/github-io-setting.png" alt="" /></p>
<p>並設置主題，後續會更改，可以不用考慮太多，選擇其一即可。<br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/github-io-theme.png" alt="" /><br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/choose-theme.png" alt="" /></p>
<p>你完成了你的網站啦！！！網址為：<code>https://使用者名稱.github.io/</code>，不過剛創建的網站可能要稍後才會顯示。</p>
<h2 id="選定好部落格的位置"><a class="markdownIt-Anchor" href="#選定好部落格的位置"></a> 選定好部落格的位置</h2>
<p>由於我們會存文章在電腦裡面，所以先選好位置。<br />
我的部落格位置是</p>
<figure class="highlight text"><table><tr><td class="code"><pre><span class="line">D 槽</span><br><span class="line">└── Blog // 直接新建一個資料夾放你的 Hexo 文件</span><br></pre></td></tr></table></figure>
<h2 id="hexo-登場"><a class="markdownIt-Anchor" href="#hexo-登場"></a> Hexo 登場！</h2>
<p>我們的主角是 Hexo，當然，也有其他的部落格工具可以使用，如：Hugo, Gatsby, Vuepress, Jekyll… 等。<br />
Hexo 的主題多，且擴充的外掛也很多，所以才使用它當我們的工具，但缺點是當文章足夠多時，上傳速度會明顯比 Hugo 慢很多（超多），不過看在主題好看的誘惑下，我還是選擇了 Hexo。<br />
接下來，來配置 Hexo 環境吧！</p>
<h3 id="前置安裝"><a class="markdownIt-Anchor" href="#前置安裝"></a> 前置安裝</h3>
<p>在使用 Hexo 之前，請先下載：</p>
<ol>
<li><span class="exturl" data-url="aHR0cHM6Ly9ub2RlanMub3JnL2VuLw==">Node.js<i class="fa fa-external-link-alt"></i></span></li>
</ol>
<p>我們選擇穩定的版本，Hexo 官方有提醒至少要大於 10.0 的版本，我們選左邊的 16.15.0，直接安裝即可。<br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/node-download.png" alt="" /></p>
<ol start="2">
<li><span class="exturl" data-url="aHR0cHM6Ly9naXQtc2NtLmNvbS8=">Git<i class="fa fa-external-link-alt"></i></span></li>
</ol>
<p>也是直接安裝即可。<br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/git-download.png" alt="" /></p>
<ol start="3">
<li><span class="exturl" data-url="aHR0cHM6Ly9jb2RlLnZpc3VhbHN0dWRpby5jb20v">Visual Studio Code<i class="fa fa-external-link-alt"></i></span></li>
</ol>
<p>這是一個具有很多外掛的文字編輯器，一樣也是直接安裝即可。<br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/vscode-download.png" alt="" /></p>
<h3 id="初始設置"><a class="markdownIt-Anchor" href="#初始設置"></a> 初始設置</h3>
<p>接著我們來當駭客（誤）<br />
我們開啟 <code>Blog</code> 位置的終端機。輸入 cmd<br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/hexo-blog.png" alt="" /></p>
<p>在 cmd 裡輸入下面指令。</p>
<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">npm install hexo-cli -g</span><br></pre></td></tr></table></figure>
<p>等待下載後，輸入 <code>hexo -v</code> 也就是 <code>hexo version</code> （想也知道你們會選 hexo -v）</p>
<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">hexo -v</span><br></pre></td></tr></table></figure>
<p>有出現各項版本就確定安裝好了！<br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/hexo-v.png" alt="" /></p>
<p>接著配置 Hexo 相關初始套件，輸入下方指令。一行一行複製，<code><資料夾名稱></code> 記得改掉，我建置的名稱是 MyBlog。</p>
<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">hexo init <資料夾名稱></span><br><span class="line"><span class="built_in">cd</span> <資料夾名稱></span><br><span class="line">npm install</span><br><span class="line">npm install hexo-deployer-git --save</span><br></pre></td></tr></table></figure>
<p>第 1 行：新建一個資料夾<br />
第 2 行：選擇資料夾並進入該資料夾<br />
第 3 行：安裝 Hexo 相關初始套件<br />
第 4 行：安裝 Git 部屬套件</p>
<p>你常用的資料應該有</p>
<figure class="highlight text"><table><tr><td class="code"><pre><span class="line">D 槽</span><br><span class="line">└── Blog</span><br><span class="line"> └── MyBlog</span><br><span class="line"> ├── package.json # 各項模組版本</span><br><span class="line"> ├── scaffolds # post, page 和 draft 模板</span><br><span class="line"> ├── source # 資源（資料）</span><br><span class="line"> | └── _posts # 文章資料夾，你所有的文章都在這</span><br><span class="line"> ├── themes # 主題（後續會教如何使用其他主題）</span><br><span class="line"> └── _config.yml # 部落格配置</span><br></pre></td></tr></table></figure>
<p>這樣你就完成 Hexo 的配置了。有沒有覺得自己超棒 (●’◡’●)</p>
<h2 id="設置-blog-相關訊息"><a class="markdownIt-Anchor" href="#設置-blog-相關訊息"></a> 設置 Blog 相關訊息</h2>
<p>接下來就要用到 VS code 啦～<br />
右鍵 D:/Blog/MyBlog，選擇 <code>以 code 開啟</code> 圖標示 VS code 的那個選項，就可以開始編輯屬於自己的部落格啦。<br />
<img src="https://raw.githubusercontent.com/huangmayor0905/image-hosting/main/img/open-by-code.png" alt="" /></p>
<p>在 6 ~ 12 行編輯部落格訊息</p>
<figure class="highlight yml"><table><tr><td class="code"><pre><span class="line"><span class="attr">title:</span> <span class="string">Blog</span> <span class="string">test</span> <span class="comment"># 部落格標題</span></span><br><span class="line"><span class="attr">subtitle:</span> <span class="string">'這是一個簡單的部落格'</span> <span class="comment"># 副標題，以單引好包起來</span></span><br><span class="line"><span class="attr">description:</span> <span class="string">''</span> <span class="comment"># 描述，以單引號包起來</span></span><br><span class="line"><span class="attr">keywords:</span> <span class="comment"># 關鍵詞，直接輸入字詞，以半形逗點隔開</span></span><br><span class="line"><span class="attr">author:</span> <span class="comment"># 作者</span></span><br><span class="line"><span class="attr">language:</span> <span class="string">zh-TW</span> <span class="comment"># 語言</span></span><br><span class="line"><span class="attr">timezone:</span> <span class="string">''</span> <span class="comment"># 空白以使用系統時間</span></span><br></pre></td></tr></table></figure>
<p>在 16 行編輯網站網址</p>
<figure class="highlight yml"><table><tr><td class="code"><pre><span class="line"><span class="attr">url:</span> <span class="string">https://username.github.io/</span></span><br></pre></td></tr></table></figure>
<p>接著設定部屬訊息，這通常在最下面</p>
<figure class="highlight yml"><table><tr><td class="code"><pre><span class="line"><span class="attr">deploy:</span></span><br><span class="line"> <span class="attr">type:</span> <span class="string">git</span></span><br><span class="line"> <span class="attr">repo:</span> <span class="string">https://github.com/username/username.github.io.git</span></span><br><span class="line"> <span class="attr">branch:</span> <span class="string">master</span></span><br></pre></td></tr></table></figure>
<p>接著部屬看看，組合技：</p>
<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">hexo cl</span><br><span class="line">hexo g</span><br><span class="line">hexo d</span><br></pre></td></tr></table></figure>
<p>終於完成了，文章有任何問題，或是不清楚的地方歡迎留言</p>

<content><![CDATA[<h2 id="簡述"><a class="markdownIt-Anchor" href="#簡述"></a> 簡述</h2>
<p>高中生涯就快告一段落了，在畢業前一週閒閒沒事，一直在想除了解題還可以幹嘛，所以更早之前做了一個地震報告的靜態網頁，現在又搞了一個踩地雷╰(*°▽°*)╯</p>
<p>主要會練習到：</p>
<ol>
<li>圖論的 <a href="https://huangmayor0905.github.io/cs/graph/bfs/">BFS</a> or DFS</li>
<li>C++ 時間戳轉當地時間</li>
<li>讀檔、寫檔（iofstream）</li>
</ol>
<span id="more"></span>
<h2 id="解說"><a class="markdownIt-Anchor" href="#解說"></a> 解說</h2>
<p>好，其實我覺得我的程式碼沒有很乾淨，都是為了分區塊才寫成函式，然後我也不太會寫 class 物件，所以就硬寫。目前比較不人性化的一點就是它是用終端機在玩，所以只能輸入座標來開格子，而且如果要插旗子的話又要叫使用者調模式，變得很難玩，所以我只讓使用者開格子。啊也建議只玩簡單，因為困難的格子有 16*30 格 (?</p>
<p>還有一點不好的地方是，如過第一手就是炸彈，我沒有做重新洗炸彈位置的機制。</p>
<div class="tabs" id="程式碼主要區塊解說"><ul class="nav-tabs"><li class="tab active"><a href="#程式碼主要區塊解說-1">difficalty</a></li><li class="tab"><a href="#程式碼主要區塊解說-2">playingGame</a></li><li class="tab"><a href="#程式碼主要區塊解說-3">writeFile</a></li><li class="tab"><a href="#程式碼主要區塊解說-4">showHistory</a></li></ul><div class="tab-content"><div class="tab-pane active" id="程式碼主要區塊解說-1"><p>控制遊戲難度，在個別遊戲難度上將地圖大小和炸彈數做調整。（其實不是，就是呼叫 playingGame 這個 function 而已）</p></div><div class="tab-pane" id="程式碼主要區塊解說-2"><p>這段在寫遊戲階段，我是用 BFS 來開格子，遇到周圍有炸彈就停止往下搜尋。</p></div><div class="tab-pane" id="程式碼主要區塊解說-3"><p>這裡用到寫檔的技巧，將耗時、遊戲時間、難度都寫進去，這樣就可以記錄歷史遊戲。</p></div><div class="tab-pane" id="程式碼主要區塊解說-4"><p>這裡用到讀檔，還有轉換時間戳的方式。將獨到的數字放進結構是 history 的 vector 容器裡並排序排名，cmp 也是為此排序所寫的。</p></div></div></div>
<p>剩下的變數就隨便啦，就是一些地圖大小、炸彈數和搜尋方向的變數。</p>
<h2 id="程式碼"><a class="markdownIt-Anchor" href="#程式碼"></a> 程式碼</h2>
<p>給大家看又臭又長的程式碼，也可以到我的 <span class="exturl" data-url="aHR0cHM6Ly9naXRodWIuY29tL2h1YW5nbWF5b3IwOTA1L0NQUC1nYW1lL2Jsb2IvbWFpbi9NaW5lc3dlZXBlci9tYWluLmNwcA==">GitHub 的 repo<i class="fa fa-external-link-alt"></i></span> 上看。</p>

<title>【C++】 認識 Hello World</title>
<url>/meeting-hello-world/</url>
<content><![CDATA[<h1 id="第一個程式認識-hello-world"><a class="markdownIt-Anchor" href="#第一個程式認識-hello-world"></a> 第一個程式，認識 Hello world</h1>
<h2 id="前言"><a class="markdownIt-Anchor" href="#前言"></a> 前言</h2>
<p>說到程式語言，Hello World 想必是程式入門時最常見的詞，它是什麼時候出現的，那為甚麼會被廣泛流傳呢？</p>
<p>首先，大部分人認為是《C 程序設計語言》此書作者之一，Brian Kernighan 在 1973 年出版的《程式語言 B 教程導論》裡首次提到。以下是當時首次提到 Hello World 的程式碼：</p>
<figure class="highlight javascript"><table><tr><td class="code"><pre><span class="line"><span class="title function_">main</span>(<span class="params"></span>){</span><br><span class="line"> extrn a,b,c;</span><br><span class="line"> <span class="title function_">putchar</span>(a); <span class="title function_">putchar</span>(b); <span class="title function_">putchar</span>(c); <span class="title function_">putchar</span>(<span class="string">'!*n'</span>);</span><br><span class="line"> }</span><br><span class="line"></span><br><span class="line">a <span class="string">'hell'</span>;</span><br><span class="line">b <span class="string">'o, w'</span>;</span><br><span class="line">c <span class="string">'orld'</span>;</span><br></pre></td></tr></table></figure>
<p>但不幸的是他受訪時，他無法準確的講述原因跟時間。「我只記得，我好像看過一幅漫畫，講述一枚雞蛋和一隻小雞的故事，在那副漫畫中，小雞說了一句：『Hello World』。」他是這樣說的。</p>
<p>結論，Hello World 的起源應該是 Brian Kernighan 小時候曾看過的漫畫。</p>
<hr />
<h2 id="用-c-實作吧"><a class="markdownIt-Anchor" href="#用-c-實作吧"></a> 用 C++ 實作吧！</h2>
<p>說了這小小的故事，其實 Hello World 也代表著程式的運行無礙，那我們也可以開始動手做看看 C++ 世界裡的 Hello World 啦！</p>
<ol>
<li>你可以使用 <span class="exturl" data-url="aHR0cHM6Ly9yZXBsaXQuY29tLw==">Repl<i class="fa fa-external-link-alt"></i></span> 線上的編譯器，註冊後，按下右上角的加號，在 Template 那一欄打上 C++，並選擇好 C++ 的環境模板。</li>
<li>在右邊 Title 欄打上這個程式專案的名稱，若是練習通常我會打上今天的日期，如：20220326，除非是特別的專案才會特別取名，如果不取名，你的專案會在左邊的側邊欄 My Repls 的 Unnamed。</li>
</ol>
<figure class="highlight cpp"><figcaption><span>程式範例</span></figcaption><table><tr><td class="code"><pre><span class="line"><span class="meta">#<span class="keyword">include</span> <span class="string"><iostream></span></span></span><br><span class="line"><span class="keyword">using</span> <span class="keyword">namespace</span> std;</span><br><span class="line"></span><br><span class="line"><span class="function"><span class="type">int</span> <span class="title">main</span><span class="params">()</span> </span>{</span><br><span class="line"> cout << <span class="string">"hello world!"</span>;</span><br><span class="line"> <span class="keyword">return</span> <span class="number">0</span>;</span><br><span class="line">}</span><br></pre></td></tr></table></figure>
<p>首先我們可以觀察看看，C++ 有人麼特別之處？如：句尾的共同處、有大括弧、小括弧等。那作者我就開始一一介紹吧！</p>
<ol>
<li>
<p>標頭檔：程式裡 <code>#include <iostream></code> 就像是工具箱，它可以叫出你想用的工具，在這裡，我們使用 <code>cout</code> ，所以每當我們使用輸出時，就會使用到這個 <code><iostream></code> 標頭檔。</p>
</li>
<li>
<p>命名空間： <code>using namespace std;</code> 叫做命名空間，它的用處就像是你在學校裡，可能會有同名的人，所以我們會叫「某班的」誰誰誰，這個「某班的」，就是我們的 std 。若我們不先在程式裡輸入這行，程式碼就要在 cout 前面多打 std:: ，這樣就會變得更複雜。所以為了方便，我們習慣在程式一開始就先打 <code>using namespace std;</code> 。簡單來說，工具也會被重複命名到，然而我們只需要用到其中一個，所以直接在程式上打 <code>using namespace std;</code> 可以免去不斷撰寫的麻煩。</p>
</li>
<li>
<p>main 函式：我們也可以說它是主程式，用來執行你撰寫的程式。我們會在一對大括號內撰寫。int 是變數型態，表整數（integer）之意，在函式前的變數型態與回傳值有關，如下兩行的 <code>return 0;</code> 。</p>
</li>
<li>
<p>輸出 cout：用來輸出箭頭後方箭頭後的字串、變數和值。</p>
</li>
<li>
<p>return 0：表示回傳值為 0，也就是程式正常結束，但現在的編譯器都會在編譯時偷偷幫你補上這行，不過！還是要多多保持多打這行的習慣會比較好。</p>
</li>
</ol>

<title>【工具】用 Spicetify 自訂自己的 Spotify 吧！</title>
<url>/spicetify/</url>
<content><![CDATA[<h2 id="為什麼要自訂主題"><a class="markdownIt-Anchor" href="#為什麼要自訂主題"></a> 為什麼要自訂主題？</h2>
<p>你是否厭倦了醜到不行的電腦版 Spotify（？）還有醜到不行的動態字幕（？）那你應該來嘗試自己自訂 Spotify。</p>
<span id="more"></span>
<h2 id="什麼是-spicetify"><a class="markdownIt-Anchor" href="#什麼是-spicetify"></a> 什麼是 Spicetify？</h2>
<p><s>辣辣的 Spotify（？）</s></p>
<p>Spicetify 是一款多功能開源軟體。透過指令或者他們提供的 Spicetify Marketplace 來使用。主要功能有：</p>
<ol>
<li>Extensions（擴充功能）</li>
<li>Themes（主題）</li>
<li>Snippets（片段微調）</li>
<li>Apps（額外的應用程式）</li>
</ol>
<p>熟悉的話，你只能嘗試跟著他們 GitHub 寫的配置訊息來做安裝或者修改。但若你已經對於網頁開發有一定理解的話（那你應該不用看我文章（沒）），那你可以嘗試製作自己的主題，或者擴充功能。</p>
<p>以下將介紹如何安裝 Spicetify。</p>
<h2 id="如何安裝-spicetify"><a class="markdownIt-Anchor" href="#如何安裝-spicetify"></a> 如何安裝 Spicetify</h2>
<p>Spicetify 可適用於 Windows、macOS 和 Linux。以下介紹 Windows 的安裝方式。其餘二者可以參考 <span class="exturl" data-url="aHR0cHM6Ly9zcGljZXRpZnkuYXBwL2RvY3MvZ2V0dGluZy1zdGFydGVkLw==">Spicetify Docs<i class="fa fa-external-link-alt"></i></span> 。</p>
<h3 id="step-1-安裝原版-spotify"><a class="markdownIt-Anchor" href="#step-1-安裝原版-spotify"></a> Step 1. 安裝原版 Spotify</h3>
<p>若你已安裝，請忽略此步驟。</p>
<p><span class="exturl" data-url="aHR0cHM6Ly93d3cuc3BvdGlmeS5jb20vdHcvZG93bmxvYWQvd2luZG93cy8=">Spotify 下載頁面<i class="fa fa-external-link-alt"></i></span></p>
<p>請按「直接從 Spotify 下載」若使用從 Microsoft Store 下載我不知道會怎樣（應該是不行），而且「直接從 Spotify 下載」會比較快。</p>
<p>然後記得登入自己的帳號。</p>
<h3 id="step-2-安裝-spicetify"><a class="markdownIt-Anchor" href="#step-2-安裝-spicetify"></a> Step 2. 安裝 Spicetify</h3>
<p>請使用 PowerShell 以系統管理員身分執行以下命令</p>
<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">iwr -useb https://raw.githubusercontent.com/spicetify/cli/main/install.ps1 | iex</span><br></pre></td></tr></table></figure>
<p>不知道 PowerShell 怎麼開，可以在「搜尋」搜 PowerShell 找到。</p>
<p>安裝過程中可能會詢問你是否要安裝 Spicetify Marketplace 請輸入 Y 或者 Enter 繼續安裝，安裝 Spicetify Marketplace 可以很方便地去安裝你想要的擴充功能和主題。</p>
<p>接著為確保 Spicetify 已經安裝成功，請在 PowerShell 嘗試輸入</p>
<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">spicetify -v</span><br></pre></td></tr></table></figure>
<p>若有出現版本號，就代表你安裝成功了。</p>
<p>再輸入以下命令以套用 Spicetify</p>
<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">spicetify apply</span><br></pre></td></tr></table></figure>
<p>稍等過後，就會看見你的 Spotify 左上角有個購物車，那個就是剛剛下載的 Marketplace，點開來後你會看見許多的擴充功能、主題等等。以下推薦幾個不錯的擴充和主題。</p>
<h2 id="spicetify-推薦擴充和主題"><a class="markdownIt-Anchor" href="#spicetify-推薦擴充和主題"></a> Spicetify 推薦擴充和主題</h2>
<h3 id="擴充推薦"><a class="markdownIt-Anchor" href="#擴充推薦"></a> 擴充推薦</h3>
<h4 id="adblock"><a class="markdownIt-Anchor" href="#adblock"></a> Adblock</h4>
<p>擋廣告用的，如果你沒有 Premium 這個必裝。</p>
<h4 id="playbar-clock"><a class="markdownIt-Anchor" href="#playbar-clock"></a> Playbar Clock</h4>
<p>提供了時間在播放時間軸下方，當你的電腦工具列是隱藏的時候很好用。</p>
<h4 id="auto-skip-videos"><a class="markdownIt-Anchor" href="#auto-skip-videos"></a> Auto Skip Videos</h4>
