订阅数:40888Is the fan on your PC so clogged with dirt that it sounds like a plane taking off? Then maybe it's time to clean your PC -- for the sake of its health as well as yours.
1. Why you need a clean
PC
At this very moment, dust bunnies may have your PC in a death grip.
Germs are certainly gathering atop your mouse and keyboard, ready
to assault your immune system. And your screen ... well, chances
are it has become smudge central.
Even great PCs can be dragged down by performance-choking dirt. Fortunately, with a few helpful products and a little effort, you can easily rescue your desktop from all that grunge.
2. Computer-cleaning
supplies
Before you even get started with this project, we recommend that
you have the following:
3. How to clean a
keyboard
Keyboard dirt actually takes two forms. Food crumbs and similar
detritus can fall between the keys; leave it alone for too long,
and you could wind up with a malfunctioning keyboard. But
potentially harmful bacteria can accumulate on the keys themselves,
too. Neglecting them may have more serious consequences: making you
sick.
Dislodge physical keyboard detritus with compressed air, then dump it.
To clean out the crumbs, hold your keyboard upside down over a wastebasket and shake it gently. Then hold the keyboard vertically (still over the wastebasket) and use a can of compressed air to spray between the keys. These two actions should dislodge most of the physical grit.
Though plenty of computer-cleaning products are on the market, most are designed to remove only ordinary dust. To obliterate both germs and dirt, antibacterial wipes such as Wet Ones Antibacterial Moist Towelettes should do the trick. Make sure your computer is off, then give the surface of the keys a once-over with the cloth.
For PCs shared among several users, consider investing in a keyboard-and-mouse set with an antimicrobial coating, such as the Logitech Cordless Desktop MX 3200 Laser. The set is made with a compound from AgIon Technologies that purports to inhibit organic growth.
Tip: While you're at it, give your mouse a thorough wipe-down -- it can collect plenty of dirt and finger grime, too.
4. Monitor-cleaning tips
A dusty, smudgy monitor may not harbour dangerous bacteria, but
it's none too attractive just the same. In fact, a screen
seriously caked with grime is unnecessarily hard on your eyes.
Turn off your CRT monitor, then wipe it clear with a nonabrasive, lint-free cloth.
The fix, unsurprisingly, lies in giving your CRT or LCD a good cleaning, but don't just wipe it with any cleaner you have under the sink. Monitors are delicate equipment and must be cleaned accordingly.
While Windex is suitable for the glass on standard CRTs, never spray it directly on the screen -- the liquid could seep under the edges of the monitor bezel and damage the circuitry within. Instead, lightly squirt some Windex on a folded piece of soft cloth or a paper towel, then use that to wipe the glass.
Another option is some form of lint-free wipes, which promise nonabrasive cleaning. Whichever method you use, your monitor should be turned off (better to see the dust and smudges you're trying to remove), and you shouldn't turn it on again until the screen is dry.
For LCD screens, however, steer clear of ammonia-based cleaners like Windex. Instead, use a soft cloth dampened with plain water. Just make sure the cloth isn't too wet, otherwise droplets could seep under the bezel and cause damage.
5. Clean your computer's
fans
Perhaps the most serious dirt-related threat to your PC is dust in
the fans. Dust constantly gets sucked inside the case. Over time,
it clogs both power-supply and cooling fans.
Eradicate dust buildup on fans with well-aimed bursts of compressed air.
As more and more dust accumulates on the blades and in the motors, the fans have to work harder. If the buildup goes unchecked, the fans may significantly slow down or fail completely. This can lead to serious overheating inside the case, which can cause component failure and, ultimately, data loss.
Once again, you'll need your trusty can of compressed air. Start by powering down your PC, removing the case lid, and locating the various fans. Starting with the power supply, blow through the internal slits from inside the chassis, aiming so dust will exit the back.
Next, blow into the intake fan (if there is one) to push more dust out the back. Finally, blow the blades of the rear exhaust fan clean. If possible, aim just beneath the center, where the motor meets the fan assembly, and blast again. Repeat the process for each fan, keeping the can upright at all times.
Now restart your PC, and while the fans are spinning, spray them once more -- very briefly -- to really send the dust flying.
Tip: Don't forget to run air over the vents on your case lid, too. If they're encrusted with dust, the fans won't be as effective expelling warm air.
6. Computer-cleaning
no-nos
While you've got the case open, you'll undoubtedly notice dust in
other places -- quite possibly a lot of it. We've seen computer
interiors absolutely caked from top to bottom.
If yours is, you might be tempted to stick a vacuum-cleaner hose inside and suck out the dust. Don't. Vacuums create static electricity, which is deadly to sensitive electronic components.
On that same note, don't be tempted to reverse the flow of your vacuum and blow the dust out of the computer. The dust inside a household vacuum can be harmful to your health, and you'll be spreading it all over your PC. Also, you risk blowing out sizable particles, which could physically damage internal components, especially if you're using a workshop vacuum.
You can find inexpensive battery-powered vacs for electronics that claim to be ideal for cleaning a PC, but we're hesitant about them, too. You'll want a machine that's rated ESD-safe, such as the 3M Electronics Vacuum. These units cost AU$585, however, and are really worth the money only for IT and service departments that need to clean PCs all the time.
The beauty of compressed air is that it's clean and particle-free. Before you start blasting, unplug your computer and take it outside -- or at least to your garage. Now, working from the top down, blow out all that dust. (Put on a dust mask, unless you want a face full of grime.) As with the fans, be sure to spray air in short bursts, keeping the can upright and the tube at least a couple of inches from the hardware.
Tip: Check all the cables and plugs inside your PC. Make sure they're fastened securely and that you haven't knocked anything loose during cleaning.
7. Get better airflow in your
PC
Dust balls can dramatically impede the airflow inside your PC,
raising case temperature to dangerous levels, but a nest of cables
can also have the same effect. (They also simply get in the way,
making it difficult to quickly replace and install components.)
In most computer enclosures, the prime space-wasting culprits are big, flat IDE ribbon cables. To keep things neat and orderly inside your PC, consider replacing these old-style cables with modern, round ones. Round IDE cables help increase airflow and reduce cable clutter.
With your computer off and its main AC power cord disconnected, simply unplug your current IDE cables and replace them with the new ones. Before replacing the case cover, power up the machine to make sure the cables are connected properly and everything works.
Tip: If you'd rather not splurge on new cables, you can still improve airflow by reorganising the old ones. For instance, fold up any excess cable and fasten it with rubber bands. Just make sure you leave a little slack so that the connectors don't become unseated easily.
南桥最近在他的BLOG《黑三角》里写了一篇文章：《美国博客写什么: 库柏访谈录》。里面谈到了美国BLOG的“自媒体”现象，从这些介绍里可以看出，美国的BLOG和中文BLOG是完全两种概念的东西。中国引入BLOG概念之后，其中的媒体性迅速被文学性代替，文学性又被娱乐性代替。有人可能会想着去讨论文化差异一类的东西，但在我看来，里面只有一条保险系数越来越高的安全曲线。写文学作品比自媒体报道安全，写八卦文章又比文学作品安全。
写什么不是我所关心的问题，因为每个人有权为自己做出最优选择。每个博客都是自由人，而不是雇佣兵，不可能用套索勒了脖子，用长杆顶到锋线上去。我感兴趣的是BLOG怎么写？是什么维持一人不断更新自己的BLOG？在中文BLOG世界里，很多人选择开博，然后写几天就又关闭了。也有人开了一段时间，就宣布去闭关，闭关完了去云游，云游中就人间蒸发。类似的话题我以前在自己的BLOG里说过，我说BLOG是为自己写。现在想起来，可能这种表达有问题，太过文学化，太罗兰小语刘墉絮语。所以，我准备换种说法：
中国人可能永远也写不好BLOG。
写不好BLOG的首要原因是看不起自己。以前在《读者》还是什么地方有那么一句话：倘若一个人看不起自己，那么连神都无法打救他。很多人写了几天，说：我写得不好，所以不想写了。好不好，这是需要对比了以后说的话。好不好，这是需要确立标准以后说的话。但是很多人不假思索地就讲出了这句话，然后就停博了。
好不好这种话我觉得非常无聊。写BLOG的时候，最基本的心态应该是：每个人等同地活在这个世界上，一切生命都有独特的价值。因此，在现实生活中有的人过得很好，有的人过得很烂，但是自杀的是绝少部分。奇怪的是，网上却有如此之多的人选择了自杀。觉得自己在网上的生命毫无价值，觉得自己在网上的表达毫无价值。问题是，你不依然在现实世界里活着吗？你不依然每一天每一天的过活。分分钟呼吸，秒秒钟感受。
在网上写BLOG是完全一样的道理，你如此过活，那么你也如此写作。文笔、深度、哲理这些东西不重要，重要的是你在网上呼吸，你在网上感受。你写下哪怕一行字，那么你也有存在过的痕迹。而且，这一行字对于网络和你个人来说，价值完全和得世界BLOG一等奖的那些博客一样。想一想看，放在现实世界里，普通人绝对不会被写进历史书里，电视台绝对不会主动请你去做访谈，编辑记者不会主动邀见你写报道。因为你的事情，你的感受，你的言论没有什么价值。别人用这样的逻辑对你，已属不公平。可为什么当有了网络，你可以随心所欲地写的时候，你却采用同样的价值观和逻辑对自己自轻自贱呢？
你不因为你觉得是否足够好，足够强而不去买早点、挤公车、看电影、谈恋爱吧？你只可能因此而拒绝竞争某个职位，参加某次比赛，出席某次表演，因为那里面的确有种成败的衡量，而买早点这些事情里没有人给你打分。写BLOG是同样的事情，你一样能在网上写你的买早点，写你的挤公车，写你的看电影，写你的经历和体验，写你的批评和意见。这里不需要你对自己做什么评判，而是需要你去过活。你上学、工作、结婚、抚养，谁能在你这一生结束时告诉你说：你这一生毫无任何意义？
这里需要一种失传了的中国式傲慢，叫自己一声：老子。王三表的BLOG每天1万人次阅览，我的BLOG每天10个人，但是老子和他一样，都是博客。新浪是一个日访问过百万的网站，我的独立BLOG每天过10人，但是老子和新浪CEO一样，都是网站站长。我觉得我的存在天大地大，因为老子一闭眼，你就是宇宙流量第一，也不干我鸟事，老子也不可能知道了。而老子一睁眼，哪怕我的BLOG每天只有老子自己看，它也是天下第一等的BLOG，因为它对于我来说最重要。
如果不承认自己的价值，如果自己看不起自己，那么BLOG的写作很难坚持下去。换个角度想一下，我的BLOG如果写到徐静蕾的流量和知名度，那么她去干什么呢？如果我的网站做到和新浪一样大一样浪，那么新浪又去做什么呢？我做不到他们，但是他们也做不到我的程度。因为他们代替不了我过活，因此不可能有和我一样的经历一样的感受。因此，我是独一无二的，我做什么都具有完全的价值。
所以，要珍视自己，要爱自己。
写不好BLOG的次要原因是没有游戏精神。总觉得提笔千言，一定要有内容有深度有思想，而且风格要睿智要隽永要幽默。总而言之，得“像那么一回事”。问题是，谁他妈规定了必须要那么去做？可不可以无聊无趣无耻无礼无稽之谈？我是这么一个人，我如此想，如此感受，但是我不那么写，我一定要追求“像那么一回事”，一定要虎头猪肚凤尾，一定要格调高雅思想深邃，这不是事逼加装逼简称二逼吗？
没有中心思想可以不可以？没有用开门见山的手法可以不可以？没有个正式的结尾，连句号都不打就结束全文了可以不可以。当然可以，为什么不可以呢？你的BLOG就是你在网上的家，你在家里也穿西装扎领带穿着皮鞋全副武装地上床睡觉？写不了一篇写一段，写不了一段写一句，写不了一句写三个字。“操你妈”总会写吧？N年以后，你翻开这一天的日志，赫然入目三个大字，当时就明白了那一天自己的全部心情，所有遭遇，一切尽在那三个字里了。这有什么不好呢？换了是我，我就觉得这三字尽占风流，完全体现了中文简洁凝练的特点，而且意味深长，回味无穷。
我并非想鼓励大家写脏话，而是说这样都做得，那么又有什么做不得的呢？写BLOG应该是一个完全松弛的状态，想到那里写到哪里，想写什么就写什么。没有人要求你写成什么样子，也没有一种范文名字叫做“博文”。这是你自己制定规则的游戏，按照你的规则来大概没有110会破门而入，印尼不会因此而发生海啸，宇宙不因此而轰地一声毁灭。当一个人觉得一定要按照某种范式写中文的时候，那么这种中文对于自己来说很难写，对于别人来说阅读是一种精神摧残。这一刻，你应该是一个人，你应该是自我灵魂附体，全神贯注在你所想表达的东西上，就像小孩子玩游戏，他绝对不没有多一秒钟时间分心想别的事情。
写不好BLOG的最后一个愿意是太在意别人，唯独不在意自己。还没有动键盘，就已经开始算计别人看了以后会是什么反应？是否有人会激烈反对自己？是否会有人批评自己文笔太烂？网络不是盛装舞会，公司讲评，没人在意你穿成什么样子，说了些什么。人生短短七十年，如果这么过活，大概有一半以上的时间是在考虑别人，哪儿有那么多“人家”？哪儿有那么多生命值得浪费在别人的眼睛里？
如果能把这种担忧和时间节约下来，多为自己考虑考虑，想一想如何才能表达自己想要表达的东西，那么可能不需要多长时间就能很流畅地写BLOG，而且绝对没有任何心理负担。写BLOG应该达到一种效果：别人来我的BLOG看我是如此在评价他，而且因此而惴惴不安。而不是自己紧张地盯着自己的留言板，一头是汗地按着F5，看看又有什么针对自己的评价。对别人达到无视的程度，那么在别人那里你才能达到被重视的程度。
BLOG的核心是自我表达，要点在于边洗澡边唱歌。这里没有舞台，也没有聚光灯，它是你的个人专场。即使真有很多人来看，你也依然得把它视为个人专场。“我”是个单数概念，“他们”是个复数概念，“他们的看法”是个不可计数的概念。用一个单数概念去满足一个不可计数概念，这是不是有点太蠢了？爷爷和孙子扛着驴上路，这就是在乎别人看法的结果。现实生活里，每个人已经扛过太多次驴了，为什么到了网上还不让那驴去吃草，自己轻轻松松上路？
很多人都有这种毛病，看不起自己，缺乏游戏精神，太在意别人的观点，所以中文BLOG是最难写的。什么时候，每个人都能深爱自己，都愿意不计成败利钝写点什么来玩，让其它人都见鬼去，什么时候中文BLOG就能变得好看一些，能坚持写下来的人也就更多一些。所有这一切，需要一个人和自己作战，达到全然“无耻”的状态，那么他在网上也就获得了最大限度的自由。有人说，BLOG是一种民主实践，从每个人都要正视自己的价值这一点上看，从每个人都有权发表自己的看法这一点上看，似乎的确如此。BLOG不以自媒体为诉求的国民，该国相信也不会存在多少新闻自由。BLOG不以自己为核心价值的国民，大概也不可能为自己在现实世界里争取到什么权利。
所以，为了自己，为了自己的那些日子，继续写BLOG吧。------------------------原文:和菜头 <中文BLOG怎么写？>

指画：中国传统绘画中的一种特殊的画法。即以画家的手指代替传统工具中的毛笔蘸墨作画，别有一种特殊趣味和技巧。故被称为指画。历史上清高其佩近人潘天涛，洪世清所作指画作画作品其影响较大。
大拇指作指画，一般情况下是很少用的。但可以用作在一些特殊技法上，如果大拇指蘸色按出小鸟的头部和一些形似大拇指形状的物象。因为大拇指的螺纹较粗，留在画面能体现指画的特点，也是一种美。

弗里德曼表示，“把这三台推土机（Windows操作系统的建立、Web的出现、工作流软件）结合起来看一下。首先是每个人创造自己的电子内容，然后可以免费在网络上传输，接着是人们可以通过网络协同工作。这三台推土机融合在一起，产生了一个平台，使更多的人可以从不同的地点，把不同的内容通过不同的方式，比任何时候更廉价地进行互相协作。” 恐慌三：来自个人的革命
老油桶静静的躺在院子的一角,陈旧印迹与残砖碎瓦,那些青苔见证了岁月,红砖和青石沉默无声,价值在岁月中风化----
也许会留下什么,也许什么都不曾留下
一千年以后
无法想象
此处会有什么
多少年会有一个轮回?也许从来就没有!
只有梦想
在岁月的流逝中呼叫!
每时每刻
时间在老去
一些事物在消失
一些新的东西在发芽,在成长
弹指一挥间
岁月已经改变---
我思念的城市已是黄昏,为何我总对你一往情深,曾经给我快乐也给我创伤,曾经给我希望也给我绝望
我在遥远的城市陌生的人群,感觉着你遥远的忧伤,我的幻想
我在遥远的城市陌生的人群,感觉着你遥远的忧伤,我的幻想
风路过的时候没能吹走,这个城市太厚的灰尘,多少次的雨水从来没有,冲掉你那沉重的忧伤,你的忧伤像我的绝望,那样漫长
风路过的时候没能吹走,这个城市太厚的灰尘,多少次的雨水从来没有,冲掉你那沉重的忧伤,你的忧伤像我的绝望,那样漫长
