電腦開機不正常,怎辦!
玩電腦那麼久,說幫人組裝電腦也數不清了,不過最近就較少玩硬體,當初年少懞懂,只知道昇級再昇級,消費了不少錢.
人家都會問:你是學本科的嗎? 你怎會懂這些? 種種,其實也只是種熱情罷了,最重要是資訊的獲得,在當時沒有網路之時代,只有從雜誌裡學習,也是最主要獲取電腦常識的途徑,我想最主要的一本雜誌就是第三波,從門外漢進級到組裝工 :>
近年來少碰,也可說成家立業後有所顧忌,coco要少花點,再則現在都是在效能及顯示卡上著眼,一張vga卡的錢,大多超過一張主機板,很敗家,也實在花不下去.
我家現在有三台電腦,p4-1.7g,其實這些都是人家不要的故障品,都是報廢後撿回來,整修一下就可以跑了,大部份的問題都是電容爆漿,在我公司裡還有我那台戰馬k2-400充當伺服器,現在還很勇健持續服務中.
最近我家小姨們也陸續發生電腦中風,一台就是常見的GSC爆漿,換換電容ok,另一台就很奇怪,原以為也是電容的問題,可是拆起主機看,端看都ok,實在看不出那裡出問題,手上又沒有除錯卡,只能土法煉鋼,一一批測,搞了2,3小時,還是無解,它的狀況是偶而開不了機,關機後不能關機,不然又死當(沒有藍色畫面,就是系統卡住).索性把電容全換了,狀況依舊.另外還有一個狀況,就是bios無法儲存,這是最後才發覺的狀況,徵結就在這裡,本想放棄了,發現徵結後,最後一試,唉!好了.bios沒電居然影響那麼大,這是從沒遇過的狀況.總之,換顆cr2032一切搞定,順便昇級一下電容(鳴~).
所以,電腦不正常時,花個時間,給它整理一下,不管是清灰塵也好,它還是可以繼續玩的.

console中文亂碼
使用Debian Lenny由主機終端登入,因為內建zh_TW.UTF-8所以會無法顯示中文字型,而是出現亂碼.若由遠端(Pietty)則正常顯示中文字型說明. 最簡單的方式是將 /etc/default/locale中的LANG="zh_TW.UTF-8"及LANGUAGE="zh_TW:zh"改成LANG="C"及LANGUAGE="C"變成英文模式即可.不過這樣一來,原來遠端登入的中文字型也會被改成英文字了.

exopolysaccharide, EPS
capsular polysaccharide and ropy polysaccharide
Exopolysaccharides are high-molecular-weight polymers that are composed of sugar residues and are secreted by a microorganism into the surrounding environment. Microorganisms synthesize a wide spectrum of multifunctional polysaccharides including intracellular polysaccharides, structural polysaccharides and extracellular polysaccharides or exopolysaccharides (EPS). Exopolysaccharides generally constitute of monosaccharides and some non-carbohydrate substituents (such as acetate, pyruvate, succinate, and phosphate). Owing to the wide diversity in composition, exopolysaccharides have found multifarious applications in various food and pharmaceutical industries. Many microbial EPS provide properties that are almost identical to the gums currently in use. With innovative approaches, efforts are underway to supersede the traditionally used plant and algal gums by their microbial counterparts. Moreover, considerable progress has been made in discovering and developing new microbial EPS that possess novel industrial significance.
The sensory benefits of the exopolysaccharides of lactic acid bacteria are well established and there is evidence for the health properties that are attributable to exopolysaccharides from lactic acid bacteria.
Capsular exopolysaccharides can protect pathogenic bacteria and contribute to their pathogenicity. Attachment of nitrogen-fixing bacteria to plant roots and soil particles, which is important for colonisation of rhizosphere and roots and for infection of the plant, can be mediated by exopolysaccharides. An example for industrial use of exopolysaccharides is the application of dextran in panettone and other breads in the bakery industry.

Bifidobacterium
Bifidobacterium is a genus of Gram-positive, non-motile, often branched anaerobic bacteria. Bifidobacteria are one of the major genera of bacteria that make up the gut flora, the bacteria that reside in the colon. Bifidobacteria aid in digestion, are associated with a lower incidence of allergies and also prevent some forms of tumor growth. Some bifidobacteria are being used as probiotics.
