一、旧家电怎么回收利用有没有好的方法

这个很好解决了，只要量达到一定的标准，可以集体用机器处理的，昌磊就可以帮你的帮

二、请问谁知道各类废旧电器的回收大约价格？如电视机，电脑，空调，冰箱，热水器等？回收这些电器主要作用是什么？

我做家电维修十余年了，处理了各种各样的电器。这些被抛弃的废旧家电，根据它的所用年限，分别处理。其中还有使用价值的整机或部件，自卖自用，多余的发往二手市场，如显像管、压缩机、电动机、CPU、内存条，显卡等，经过那些土专家用改或拼的方法，弄成能用的整机再卖；没使用价值的，就分名别类真的当废品卖掉。干这行的人多的很，利润颇丰。你还有什么问题，记着追问。

三、怎么收藏数码的东西？

如何隐藏你的数码“收藏品”

确保那些“不雅”文件被好好地隐藏在你的电脑之中

近段时间，很多人提到了关于数码文件的保存的事情，这使我想到了一个问题：那些我们不想删除的东西怎么保存？你知道，就是那些不雅的文件。不要假装你不知道我在说什么，你知道的。

说实在，这件事看上去挺复杂的。但实际上，它并没有你想的那么复杂。无论是谁，一定会有那么一些资料，无论是从它们的存在而言还是从你的角度而言，都是很私人的东西。就拿你看的黄书打个比方（你一定有在看），这个事实，还有这本书，都是属于你自己的。但很显然，这些东西没有必要成为你的数字生活的一部分，或者，成为你的数字遗产的一部分（但愿不会如此）。所以现在，我将提供给你几个办法，确保你的“私人收藏”保存在合乎情理，同时又不被发现的隐秘地点。

等级一：混淆术

有谁从没有创建过一个名字为“商务”，而且里面只有各种各样的商务存档的文件夹？要知道，这是一个神圣的传统，在过去的20年之间被几乎所有使用电脑的人遵从。同时，就像那个不仅白痴而且可笑的名字一样，这样做也许会有一丁点用处。

曾经有段时间，操作系统的文件结构是被完完全全的隐藏的。你的家人或者配偶永远不会因为某种原因去浏览C:/Windows/System32，更不会去阅读你狡猾地隐藏于此的“Nrop”文件夹。这个文件夹永远不会暴露，除非有人负极的去搜索关联文件。

但是到了今天，事情已经不一样了。几乎所有的操作系统都有深度搜索和详细搜索功能，就像是MAC OS X的Spotlight和windows7的搜索栏一样，这些东西可以轻轻松松的找出深深地藏在系统文件夹中的文件。它们能在文件定位的基础上将文件分类，所以你深藏于某处的视频和你放在“我的视频”文件夹中的视频一样，很容易就能被找到。只有在你能隐藏材料，并且不要让你那怪异而且缺少趣味，并且看了看之后觉得更加怪异的视频收藏被你刚刚失去亲人的家人发现，（这里对应前文的数字遗产）这种方式就能提供一点点微不足道的保护。

在“嘘”这个不断变化的古老的章节中，有一种很有效的办法来隐藏文件，那就是值得永远信任的文件改名大法。下面我们来介绍一下这种法：首先，保存你的文件，把它的文件名更改为某个看上去无害的名字，最后把文件扩展名改成像谜一样的玩意，比如说把LadiesEatingFriedPigsFeetInLingerie.avi这个名字改为lefpfil.dat。说实在，这样做对于像是.avi=dat .mpeg=.dll, .mp4=.lib or .jpg=doxc这种密码表的制作有很大的推进作用。

现在，看上去以上的方法似乎使实现了你一开始的目标，但是对于长远来说，这种操作似乎有点难以控制，而且这样做对于文件的完整性也有影响。所以，我们还要接着探寻新的方法。

等级二：加密术

话说，“encryption”这个词实际上来自于间谍电影，啊，说到这个，能想到的自认就是那隐藏于黑暗之中的国家机构和比任何事物都要卑微的讨厌的家伙。但事实是：加密术可以说是超级简单的。而且加密术几乎是100%有效地手段来隐藏你的文件。除非有有人很严肃的要求详细的查看你电脑上的每一个文件。要是发生了这种事，请不要说出是我教你怎么隐藏文件的，谢谢！

Mac OS X下的隐藏方法：在你的best option这儿建立一个密码保护，这后你要做的更加简单，合并你的文件夹，之后将你的文件放置在不能被建立搜索目录的文件夹中。最后将一个现存的文件夹打包成一个加密的.DMG文件（这是一种镜像文件，你可以通过双击打开它）。就像这样：

·打开Disk Utility（在Spotlight里面搜索Disk Utility）

·文件>新建>从文件夹制作镜像

·选择文件夹，点击镜像

·选择加密（128bit AES加密）

·选择一个第一无二的密码

之后，完成！现在，你有一个名字为whateveryouwant.dmg的文件，这个文件不可能被你之外的任何人查看或者打开，这就是你的私人不雅胶囊！（呕）

Windows下的操作：

想在windows7或者vista下建立一个密码保护的文件，你需要下载项WinRAR或者WinZip之类的第三方程序。实际上你需要的仅仅只是PeaZip这个免费程序，这比你大部分的软件都要好用百倍。之后：

·打开PeaZip

·文件>新建文件

·选择你想保存在加密文件中的文档

·在输出选项栏中点击加密按钮

·选择“加密文件名”

·选择文件格式为“PEA”（这儿你在使用的其实是这个软件的专用格式，就像是ZIP一样，但这意味着这个文件更难以被确认）

之后，你就得到你想要的了。

等级三：清算术

最后，我要很严肃的告诉你，孩子，别再下载不和谐的内容了。既然你已经能在网络上找到那些文件了，那就让它只存在于网上吧。即时在线视频，浏览图片，这都是很简单的。

火狐，Chrome，Safari，甚至IE都有隐私浏览模式，在这个模式下，你的浏览记录，Cookies记录，各种各样的缓存都不会被记录下来。使用这些浏览器，相信你的数字生活一定会显得非常“干净”。

How to hide your digital ‘collection’

Make sure risqué files on your computer stay hidden

All this talk about preserving digital legacies got me thinking: What about the bits we don't want to leave behind? Y'know, the risqué material? Don't pretend you don't know what I'm talking about.

This seems like a complicated subject. It's not. There's some data that's private, both in terms of content as well as the very fact of its existence, and your viewing of it. Let's say you look at porn. (You do.) This fact — not just the porn itself — belongs to you. There's no need for it to be a discoverable part of your digital life, or, god forbid, your digital legacy. Here's how to make sure your private collections are in order, and out of sight.

Level one: Obfuscation

Who hasn't created a folder called Business only to fill it with an entirely differently kind of business? It's a hallowed tradition, enjoyed by nearly everyone who's used a computer in the last 20 years. And as ridiculous and inept as it sounds, it probably worked—then.

There was a time when hiding a folder deep within an operating system's file structure actually hid it. Family members and spouses never had a reason to explore C:/Windows/System32, much less the Nrop folder you cunningly stashed there. And unless anyone went out of their way to search for incriminating content, it just wouldn't come up.

Today, things are different. Both major OSes have deeply integrated and everpresent search features — Spotlight in OS X and Start menu search in Windows 7 — which bring the depths of your file system bubbling to the surface with alarming ease and frequency. They prioritize file types over file locations, so your buried videos are just about as discoverable as if they were stored your My Videos folder. As far as hiding your stuff, and keeping your bereaved family from discovering your bizarre-but-harmless-but-still-pretty-bizarre video collection, this offers only the slightest protection.

The section age-old variation on pornfuscation is the trusty file rename. Here's how it goes: Save your files, change their names to something innocuous, and switch their file extensions to something inscrutable. LadiesEatingFriedPigsFeetInLingerie.avi becomes lefpfil.dat. And it helps to sew together a little cipher, too. Something like: .avi=dat .mpeg=.dll, .mp4=.lib or .jpg=doxc.

While this will probably accomplish your goals with almost no initial effort, it's pretty unwieldy in the long term, and far from failsafe.

Level two: Encryption

The word encryption evokes spy films, shady government agencies and more than anything, nerds. But here's the thing: It's actually super easy. It's also nearly 100 percent effective, unless someone very serious is looking very seriously for something seriously incriminating on your computer, in which case I probably don't want to help you out anyway. So!

Mac OS X: Creating a password-protected archive is your best option here. It's dead simple, consolidates your files, and puts your stuff one extra layer of abstraction further away from search indices and the like. To make a passworded .DMG file (an image/archive file that you can open with a simple click) from an existing folder, just do this:

? Open Disk Utility (Spotlight search Disk Utility)

? File>New>Disk Image from Folder

? Select the folder, click Image

? Select encryption (128-bit AES will do)

? Choose a unique password

And that's it! Now you have a whateveryouwant.dmg file that can't be viewed, opened or edited by anyone but yourself. Your very own little lockable porn capsule! (Ugh.)

Windows

To create a password-protected archive in Windows Vista or 7, you'll want to download a third-party archive utility, like WinZip or WinRAR. And by like WinZip or WinRAR, I mean just download PeaZip. It's free, and better than the software you're used to. Then:

? Open PeaZip

? File>Create archive

? Select the files you want in the archive

? Click the Lock icon under the Output selector

? Select Encrypt also file names

? Select archive type PEA (the fact that you're using this program's proprietary format, as opposed to something like ZIP, means that it'll be even less identifiable as, well, what it is.)

And there you go.

Level three: Liquidation

Seriously, people, stop storing incriminating material on your computer. You're already getting this stuff from the internet, so just leave it on the internet. Stream videos online, and look at pictures without downloading them. It's easy.

Firefox, Chrome, Safari and even Internet Explorer have private browsing modes, which don't accumulate history, cookies, or local caches of any kind. Use them. Your digital self will thank you.
