										<content:encoded><![CDATA[<p style="font-size: 16px; line-height: 26px;">過年期間總是會見到平日難得聚首的親戚們，這是幸福的，席間忽然被年輕一輩問到關於用比特幣賺錢的問題，這個我是幾年前有注意過採礦賺錢的可能性，但是從來沒有投入過，今日再度研究一下，真的時不我予了，5年前可能用GPU採礦還能賺到錢，現在幾乎很難了，Bitcoin的採礦也已經進入規模化的時代，如果還想著要用個人的CPU或是GPU去採礦，應該連電費都賺不到了。</p>
<p style="font-size: 16px; line-height: 26px;">下面是在Linux系統上安裝CPU Miner程式的步驟：</p>
<p><span id="more-190"></span></p>

<p style="font-size: 16px; line-height: 26px;">測試結果：</p>

<p style="font-size: 16px; line-height: 26px;">問題就是出在上面的 76.95 khash/s，以 Intel i5 CPU 這種一般家用等級的運算效能，根本上不了檯面，至少我是放棄了，興趣的可以繼續參考下面的網頁資料。</p>

										<content:encoded><![CDATA[<p style="font-size: 16px; line-height: 26px;">要讓網頁內容達到中文繁簡體的自動轉換，最簡單的方式就是用字表轉換，所以你要先收集繁體跟簡體的差異字，然後用 Lookup Table 的方式去做轉換即可，那麼中文繁簡體的差異字到底有多少個字呢？我自己收集到的部份一共有3060個字，我不是什麼語言研究的專家，所以這個數字不是學術等級的精準，但是仰賴數十位大陸朋友的真人實測，他們一致認為透過這3060個字表轉換後的文章內容，在閱讀上實用性已經很高了。</p>
<p><span id="more-182"></span></p>
<p style="font-size: 16px; line-height: 26px;">如果要求還要再更高，那就進入語意分析的領域了，很抱歉，我沒有那個水準去談語意分析。什麼是語意分析？例如說台灣說&#8221;當機&#8221;等於大陸說&#8221;死機&#8221;，台灣說&#8221;送出&#8221;等於大陸說&#8221;提交&#8221;&#8230;等等這一類就屬於語意分析的範圍，這個難度高很多，也會耗費更多計算資源，但是就像前面說的，透過簡單的字表轉換，其實已經達到實用的等級，實作上跟程式的運行效率都有不錯的CP值。</p>
<p style="font-size: 16px; line-height: 26px;">實作上，繁體轉簡體是容易的，而且效果也比較好，因為很多繁體字經過簡化後，會對應到同一個簡體字，也因為這個特性，簡轉繁難度高上許多，單純的字表轉換會出現語意不同的情況，不像繁轉簡，文章語意幾乎都是通順的，舉例來說：</p>
<p style="font-size: 16px;"><img decoding="async" class=" size-full wp-image-180" src="http://codeant.cc/wp-content/uploads/2017/01/images_Screenshot_from_2017-01-19_121057.png" alt="Screenshot from 2017 01 19 121057" width="199" height="30" /></p>
<p style="font-size: 16px; line-height: 26px;">在進行簡體轉繁體的時候，你要選哪一個？所以簡轉繁要做的好，幾乎都要考慮語意分析！</p>
<p style="font-size: 16px; line-height: 26px;">還有就是繁體常用字等於部份簡體字的問題，舉例來說：</p>
<p style="font-size: 16px;"><img decoding="async" class=" size-full wp-image-181" src="http://codeant.cc/wp-content/uploads/2017/01/images_Screenshot_from_2017-01-19_121114.png" alt="Screenshot from 2017 01 19 121114" width="361" height="55" srcset="http://codeant.cc/wp-content/uploads/2017/01/images_Screenshot_from_2017-01-19_121114.png 361w, http://codeant.cc/wp-content/uploads/2017/01/images_Screenshot_from_2017-01-19_121114-300x46.png 300w" sizes="(max-width: 361px) 100vw, 361px" /></p>
<p style="font-size: 16px; line-height: 26px;">前面說了一大堆，到底要如何去達到網頁的自動繁簡互轉呢？我個人是用判斷HTTP_ACCEPT_LANGUAGE的方式為主，再加上判斷HTTP_USER_AGENT為輔，這樣可以達到大部分來自中國大陸的訪問者，都是看到簡體網頁的內容，這其中當然也包含百度搜尋引擎的蜘蛛，PHP的程式碼如下：</p>
<pre class="prettyprint" style="font-family: 'Courier New', Courier,'gMuli'; font-size: 14px;">$trans = FALSE;  

if (!empty($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {         
    $lang  = explode("," , $_SERVER['HTTP_ACCEPT_LANGUAGE']);          

    if (($lang[0] == 'zh-cn') || ($lang[0] == 'zh-CN')) {
        $trans = TRUE;         
    } 
} 

if (!$trans &amp;&amp; !empty($_SERVER['HTTP_USER_AGENT']) &amp;&amp; 
    strstr($_SERVER['HTTP_USER_AGENT'], "Baidu")) 
{         
    $trans = TRUE; 
} // From TW -&gt; CN 

if ($trans) {         
    require_once '/include/TWtoCN.php';         
    $app = ant_zhtw2cn($app); 
}</pre>
<p style="font-size: 16px; line-height: 26px;">上面這一段 Code ，我大概使用快十年了，如果你是一個以繁體中文為主的網站，同時也想對使用簡體中文的朋友們做到 User Friendly ，這樣就已經很足夠了，當然有部份人士的個性是屬於多毛症的，那就滿足不了。</p>

										<content:encoded><![CDATA[<p style="font-size: 16px; line-height: 26px;">分享一下在網路上找到，用 <span style="color: #333333; font-family: NotoSansTC, gMuli, 'Helvetica Neue', Helvetica, Arial, sans-serif;">PHP 開發的 HTML, CSS, JavaScript minifier</span>，也有人把 minify 稱之為壓縮（compress），我個人認為這並不是真正意義上的&#8221;壓縮&#8221;，&#8221;壓縮&#8221;應該是像是 gzip 或是 apache 的 mod_deflate 才是，所以 minify 會是比較好的說法，minify 是一種瘦身工具，去除了不必要的多餘字元，進而達到減少檔案原始 size 的方式，實際測試呢？本站的首頁原始大小約為 20617 bytes，經過這隻程式 minify 之後，網頁瘦身成 19117 bytes，成功減重 7.27%。</p>

<p style="font-size: 16px; line-height: 26px;">客倌們千萬不要小看這減少的 1500 bytes，而認為這只是區區小數目，這剛好是一個 Ethernet MTU 的大小，也就是說當訪客瀏覽你的網站時，每一次可以節省一個封包的傳送，如果你的網站有百萬PV，就可以節省下將近 1.5 GB 的傳輸流量，有道是『滴水穿石，積沙成塔』，更何況『天下武功，唯快不破』，網路也是一樣的道理。</p>
<p style="font-size: 16px; line-height: 26px;">如果啟用 gzip 壓縮呢？剛剛前面的19117 bytes 會進一步縮減到 6700 bytes 左右，這才是真正的壓縮，一般來說可以減少 60-70％ 的網頁大小，簡單來說：</p>
<p style="font-size: 16px; line-height: 26px;">網頁壓縮(gzip or mod_deflate) ＋ Minifier 等於網頁傳輸的最佳瘦身方案。</p>

										<content:encoded><![CDATA[<p style="text-align: left;"><span style="font-size: 16px; line-height: 26px;">沒有比它CP值更高的大光圈鏡頭了，如果你是 Canon 的 DSLR 用戶。在 EF 50 F1.8 STM 發佈的時後，我就已經決定要第一時間入手，替換掉我手上的 EF 50 1.8 II，最主要的因素就是採用了 STM 對焦馬達，可以提供更快、更準、更安靜的對焦。接下來就分享一下實拍的照片及心得。</span></p>
<p>  <span id="more-145"></span>  </p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">實際的使用感受，加入了STM馬達後的對焦速度，表現確實有所提升，但是仍然比不上使用USM的鏡頭（以EF 24-70 F4 L IS USM為例），而且這個速度上的差異是明顯的，而對焦時馬達的噪音則是大大的降低了，原本我預期STM馬達會非常安靜，但體驗後依然是USM要更為安靜一些（同樣以EF 24-70 F4 L IS USM為比較對象），也許是我一開始的期待太高，所以對於對焦速度跟噪音，我覺得還是有點不夠好的，但實際上絕對是不成問題，毫無疑問是比前代鏡頭有大大的進步。如果把EF 85 F1.2 L II USM 當作比較的對象呢？這支的對焦算是USM馬達中出名的慢，我個人是覺得EF 50 F1.8 STM是有快上那麼一點點，但不是差很多，大概就是這樣對焦速度。<br /></span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">不同於USM的全時手動對焦感受，這隻鏡頭在進行手動對焦時，會有拖著馬達走的感覺，此時也確實可以聽見STM的馬達聲，某種程度上增加了阻尼感，但我相信久了對馬達也會是一種另類的負擔，而USM則是輕快沒有拖拉感而且無聲。而且這顆STM鏡頭的全時手動對焦，在非進行對焦的狀態下，是不起作用的，即便相機是開啟的，轉動對焦環也不會有反應，剛入手時，第一個感覺就像是不支援全時手動對焦一樣。而且STM在機身斷電的狀態下是無法進行手動對焦的，即便切換到MF模式也是一樣。</span></p>
<p style="text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"><img loading="lazy" decoding="async" class=" size-full wp-image-95" src="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2456.jpg" alt="img 2456" width="660" height="440" srcset="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2456.jpg 660w, http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2456-300x200.jpg 300w" sizes="auto, (max-width: 660px) 100vw, 660px" /></span></p>
<p style="text-align: left;"><span style="font-size: 16px; line-height: 26px;">鏡身的整體質感及做工，以這個價位來說，是沒什麼好抱怨的，還是一樣，超值。鏡頭的前方鏡片實際上內凹了1公分左右，某種程度提供保護跟遮光的效果，以這隻鏡頭的價位而言，我個人是不會上保護鏡或是遮光罩了，就讓它裸奔，一路拍到掛為止。<br /></span></p>
<p style="text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"><img loading="lazy" decoding="async" class=" size-full wp-image-96" src="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2552.jpg" alt="img 2552" width="660" height="440" srcset="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2552.jpg 660w, http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2552-300x200.jpg 300w" sizes="auto, (max-width: 660px) 100vw, 660px" /></span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">鏡頭的體積跟重量，依然是非常的輕盈，搭配上 6D 之後，就是目前市面上最平價也最輕量的全幅大光圈組合。這兩天試拍下來，這樣的搭配非常不錯，長時間拍攝並不會造成負擔，有了大光圈的加持，低光源的環境下也多了一點拍攝的可能性。還是開頭的那一句，一整個CP值爆高。</span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">鏡頭在對焦時會有伸縮的情況，並非內對焦的方式，最近對焦會伸至最長，</span></p>
<p style="text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"><img loading="lazy" decoding="async" class=" size-full wp-image-97" src="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2458.jpg" alt="img 2458" width="660" height="440" srcset="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2458.jpg 660w, http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2458-300x200.jpg 300w" sizes="auto, (max-width: 660px) 100vw, 660px" /></span></p>
<p style="text-align: left;"><span style="font-size: 16px; line-height: 26px;">無限遠對焦時，鏡頭處於縮至最短的狀況，</span></p>
<p style="text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"><img loading="lazy" decoding="async" class=" size-full wp-image-98" src="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2460.jpg" alt="img 2460" width="660" height="440" srcset="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2460.jpg 660w, http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2460-300x200.jpg 300w" sizes="auto, (max-width: 660px) 100vw, 660px" /></span></p>
<p style="text-align: left;"><span style="font-size: 16px; line-height: 26px;">跟EF 85 F1.2 L II USM 站在一起，EF 50 F1.8 STM 的體積跟重量，根本就是 nothing，</span></p>
<p style="text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"><img loading="lazy" decoding="async" class=" size-full wp-image-99" src="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2453.jpg" alt="img 2453" width="660" height="440" srcset="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2453.jpg 660w, http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_Blog_img_2453-300x200.jpg 300w" sizes="auto, (max-width: 660px) 100vw, 660px" /></span></p>
<p style="text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"></span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">下面來看看簡易的解析度測試:</span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"></span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">邊緣，光圈 F1.8</span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">EF 50 F1.8 STM</span></p>
<p style="text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"><img loading="lazy" decoding="async" class=" size-full wp-image-100" src="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_ef-50-f1.8-stm-corner-01.jpg" alt="ef-50-f1.8-stm-corner-01" width="660" height="450" srcset="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_ef-50-f1.8-stm-corner-01.jpg 660w, http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_ef-50-f1.8-stm-corner-01-300x205.jpg 300w" sizes="auto, (max-width: 660px) 100vw, 660px" /></span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">坦白說，開放光圈下的邊緣解析度實在是很糟糕。49mm 的口徑，F1.8的最大光圈，大概也就這樣了，失光現象也很重。<br /></span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"></span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">EF 85 F1.2 L II USM</span></p>
<p style="text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"><img loading="lazy" decoding="async" class=" size-full wp-image-101" src="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_ef-85-f1.2-corner-02.jpg" alt="ef-85-f1.2-corner-02" width="660" height="450" srcset="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_ef-85-f1.2-corner-02.jpg 660w, http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_ef-85-f1.2-corner-02-300x205.jpg 300w" sizes="auto, (max-width: 660px) 100vw, 660px" /></span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">只能說一分錢一分貨。這裡沒有放上F1.2最大光圈的測試照，畢竟主角是EF 50 F1.8 STM，但實測照片還是夠清晰的，只有比這張要軟一點點而已，也就是說EF 85 F1.2 II USM 的最大光圈就是可用的。<br /></span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"></span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">邊緣，光圈 F2.8</span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">EF 50 F1.8 STM</span></p>
<p style="text-align: left;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"><img loading="lazy" decoding="async" class=" size-full wp-image-102" src="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_ef-50-f1.8-stm-corner-02.jpg" alt="ef-50-f1.8-stm-corner-02" width="660" height="450" srcset="http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_ef-50-f1.8-stm-corner-02.jpg 660w, http://codeant.cc/wp-content/uploads/2015/05/images_phocagallery_ef-50-f1.8-stm-corner-02-300x205.jpg 300w" sizes="auto, (max-width: 660px) 100vw, 660px" /></span></p>

										<content:encoded><![CDATA[<p style="text-align: justify;"><span style="font-size: 16px; line-height: 26px;">使用數位相機拍攝時，如果遇到高反差的畫面，高亮度的區域很容易爆掉，這是因為感光元件的動態寬容度，比起人眼或是傳統的銀鹽底片（Film），是相對較差的，Canon 6D 有提供高光色調優先（High Tone Priority，D+）的設定選項，目的就是為了保留高光區域的細節，在這邊透過實際的拍攝，測試其效果如何？</span></p>
<p>  <span id="more-93"></span>  </p>
<p style="text-align: justify;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"></span></p>
<p style="text-align: justify;"><span style="font-size: 16px; line-height: 26px;">高光色調優先這個設定選項不同於相片風格只對JPEG直出有作用，而是連 RAW 檔也會起作用，簡單來說，就是高光色調優先無法在後制的作業過程中開啟，而必須在拍攝之初於相機上先行設定，Canon 6D 的機身 JPEG 引擎並非 RIT，所以採用 中性模式+銳利度7 的設定也無法喚回失去的高光細節。</span></p>
<p style="font-size: 16px; line-height: 26px; text-align: justify;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;"></span></p>
<p style="font-size: 16px; line-height: 26px; text-align: justify;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">在近年發售的Canon相機上，想要盡可能的保留高光細節，以原廠的方式來說，就是開啟高光色調優先+DLO，DLO（<span class="st">Digital Lens Optimizer</span>）必須拍攝RAW檔，然後進DPP後製開啟這個功能，這篇文章內先不討論DLO，日後再專文介紹這個Canon DPP獨有的強悍武器。</span></p>
<p style="font-size: 16px; line-height: 26px; text-align: justify;"><span style="font-size: 12pt; font-family: comic sans ms,sans-serif;">如果是採取機身直出JPEG的方式，高光色調優先的開啟就成了目前Canon相機保留高光細節的最佳方案了。下面就是Canon 6D 高光色調優先（D+）及一般狀態下（OFF）的畫質測試。兩張為一組，同組內的拍攝條件（光圈/快門/ISO值）相同，因為開啟高光色調優先之後，相機的最低ISO值為200，所以一律以ISO 200來進行拍攝，相片風格設定為風景模式，銳利度為4（初始值），機身直出JPEG，</span></p>

										<content:encoded><![CDATA[<p style="text-align: left;"><span style="font-size: 16px; line-height: 26px;">&nbsp; &nbsp;手機應用程式也是相當有趣也有發展的前景，目前來說智慧型手機已經成為一大熱門，不管是Apple&nbsp;iOS或是Google&nbsp;Android系統，每天都有需多新的應用程式出現。</span></p>
<p>  <span id="more-32"></span>  </p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-family: 'comic sans ms', sans-serif; font-size: 12pt;">&nbsp;&nbsp;&nbsp; 由於智慧型手機豐富的使用者介面、觸控功能以及多工的作業系統，隨著科技進步、開放原始碼的流行，智慧型手機上提供的服務可能會越來越多、越來越豐富，現在的小孩子第一次上網可能就是透過手機，而不是電腦。</span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-family: 'comic sans ms', sans-serif; font-size: 12pt;">&nbsp;&nbsp;&nbsp; Google最近進行了一份美國智慧型手機用戶使用行為的調查，93%用戶會在家中使用智慧型手機、81%會用來上網、77%會在上面搜尋、72%會和其他媒體一起同時使用、三分之一會一邊看電視一邊用、45%會運用智慧型手機來管理並籌畫活動、然後39%用戶承認自己曾經帶到廁所使用過、而有五分之一表示只要能繼續使用智慧型手機，他們願意放棄有線電視。</span></p>
<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-family: 'comic sans ms', sans-serif; font-size: 12pt;">&nbsp;&nbsp;&nbsp; 手機應用程式的蓬勃發展也衍生出許多新的商業模式，對網路系統營運商的營收也有增加，也相當程度的改善人們的生活模式。</span></p>

<p style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-size: 12pt; font-family: 'comic sans ms', sans-serif;">&nbsp; &nbsp;&nbsp;目前4G無線寬頻分為兩大標準，LTE與WiMAX，兩者在技術上約有80％是相同的，主要都採用了MIMO的技術。兩岸在無線寬頻通訊發展上的差異簡表如下：</span></p>

										<content:encoded><![CDATA[<p style="text-align: left;"><span style="font-size: 16px; line-height: 26px;">惡意電子郵件（Malicious Email）通常被廣泛地稱做垃圾信或廣告信，英文的泛稱則為「SPAM」。根據統計，目前在Internet上所傳遞之電子郵件，「SPAM」占總量的比率高達70%。</span></p>
<p>  <span id="more-30"></span>  </p>
<div style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-family: 'comic sans ms', sans-serif; font-size: 12pt;">換句話說，如果沒有採取任何過濾、防護措施，那麼每十封收到的電子郵件當中，可能只有三封才是真正有效的信件。由此可知，「SPAM」對於使用者、網路頻寬、郵件伺服器甚至網路文化的影響，遠遠超乎我們想像。</span></div>
<div style="font-size: 16px; line-height: 26px; text-align: left;">
<div style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-family: 'comic sans ms', sans-serif; font-size: 12pt;"></span></div>
<div style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-family: 'comic sans ms', sans-serif; font-size: 12pt;">長久以來，電子郵件使用者最常提出的抱怨的，不外乎信箱被廣告信件塞滿。使用者必須浪費許多時間分類處理，有時甚至造成正常信件被誤刪，錯失重要資訊。然而隨著電子郵件服務普及，資訊科技進步，這類惱人的現象非但沒有獲得任何改善，惡意信件反而經過演化變種，發展出更多種類的威脅，對於個人及企業之資訊安全防護，產生嚴重衝擊。</span></div>
<div style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-family: 'comic sans ms', sans-serif; font-size: 12pt;"></span></div>
<div style="font-size: 16px; line-height: 26px; text-align: left;"><span style="font-family: 'comic sans ms', sans-serif; font-size: 12pt;">總而言之，雖然外在的威脅與日遽增，然而養成良好的使用習慣，隨時保持高度警覺，可以有效降低入侵中毒或個人資料外洩的機會。最後也得再度提醒使用者，除了電子郵件之外，同樣的自保之道，也相同適用於網站瀏覽及P2P檔案交換的情況，建議提高警覺，保護自我。</span></div>
