I am not mad: yes, we do believe the site to be a spider googlebot easily.
Why would it? Simple, because in some cases this trick saves us the "trouble" of having to adjust to various sites, blogs, forums during our research on the web.

The typical scenario is where, when we type a search on google and follow one of the results we are faced with a request for registration, required to access the desired content. Which sometimes is very annoying.

Clearly, then Googlebot , the famous spider (or crawler) that at any time scours the Web looking for content to be indexed, has opened the doors a bit more than others. The reason I have already said as spider analyzes and indexes the pages, indexing means popularity, popularity means increased visibility and wanting more money for the webmaster, even if their pages show a bit of advertising.
That's why everyone should have an interest to read its content to googlebot in office, even if you normally would not be accessible to unregistered users, and this is what happens for a simple discussion of vision.

How it works?

Just change the User-agent of your browser, a text string ( header ) sent to different servers during the http requests and used to identify the client (browser) used for navigation.
Quite simply, if you have firefox, the string sent is:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; it; rv:1.9.0.3) Gecko/2008092417 Firefox/3.0.3
Googlebot also sends a header when knocking on doors of a web page, and it is this:
User-Agent: Googlebot/2.1 (+http://www.googlebot.com/bot.html)

If you want to try I recommend you use Firefox , installing a lightweight add-ons that change at will the HTTP header: Modify-Headers .
Install it and add the string as googlebot image, activate the change and have fun.
My advice is to turn the header only when you do research, because some domains tend to feed the bot Lo-Fi versions of pages.

DTIData makes available on its official blog a series of articles and tips for the Protection of personal data.
About CHKDSK (checkdisk) utility available in DOS and Windows systems for file system check, Jacqui Best explains why it is important to do a full backup before you use it when the media is not working properly are important data.

CHKDSK is a tool developed for the control and restore the integrity of the file system, can also be used to detect bad sectors and ensure that these are ignored by the system and finally is the first built-in resource available to the system when Windows will not start.
What is usually ignored is that CHKDSK was not thought to check the integrity of the data.
I quote from a Microsoft Knowledge Base article that discusses the utility function:

Also Notes That NTFS Does Not Guarantee the integrity of user data after an instance of disk corruption, even if you Immediately run a full CHKDSK operation. There Might Be That CHKDSK can not recover files, and files CHKDSK does recover That Might still be internally corrupted. It remains vitally important That You protect mission-critical data by performing periodic backups or by using Some Other robust method of data recovery.

If you want to minimize the possibility of losing your data, the advice is to make a disk image before groped checkdisk with the recovery, as well as you lose (much) time and further damage the hard drive could make hard work even for a specialist.

Disable Chkdsk

To prevent any unwanted execution of the command (windows tends to schedule the first reboot in case of errors), at least until the data that concern us are not safe, you can use a little trick:
from a DOS prompt, that if the system we use does not start even in safe mode, we type
Chkntfs /x C:
where instead of <C:> enter the drive letter of the damaged disc.

We talk about openDNS from Italy when we started to feel a strong smell of censorship. Not that these practices had never been implemented by our government (see the long list of sites on gambling that have been banned), but the straw that broke the camel's back was definitely the shutdown of The Pirate Bay , one of the largest BitTorrent trackers in the world.

Those of TPB did talk about him far and wide thanks to their rebellion and protest against the policies of 'country locked' imposed by certain countries that absolutely personal-opinion-have simply fueled the curiosity of people against these channels, because in fact they are resources that have something really interesting and facilitate inter alia, the disclosure of a large amount of free material, such as Linux distributions.

Makes its way OpenDNS at the right time with a DNS service of high quality, competitive, because based on generosity, cooperation, and the 'independence from providers, unfortunately, subject to government influence.

In addition to improving immune to the effects of the coutry lock is definitely superior service and favorable than that provided by common ISP, since the offer has more than reliability, many additional services custom designed for businesses, schools, but also common for home networks. Personally I would be willing to pay even if that was not totally free.
To access these services is only necessary registration, website: free, immediate and open to all, while only service to use the Domain Name System is sufficient to indicate the connection properties in the DNS addresses 208.67.222.222 and 208.67.220.220, without no inscription.

Reasons for use openDNS

As I said, using these DNS 'free' you can circumvent the censorship just because the service is free from any interest to the detriment of the highest user satisfaction.
But let's start talking about security and content filtering: the good one.
The great advantage of this solution is the protection against phishing and fraud for surfers, but you can choose between 6 different levels of filtering for your home or corporate network.
Precise categories and blocks are managed by the community of users of the service (only a few million) through polls and vote on domain names and addresses whose nature is still uncertain. If a valid e escaped content filtering, in addition to report it immediately, you can lock in your network.

here are six possibilities:

• high (block sites in categories: phishing, video sharing, entertainment, social networking, pornography, warez, illegal)
• (grabbing the categories: phishing, pornography, warez-illegal)
• Low (protects against phishing and block pornography)
• minimal (protects against phishing) * recommended mode
• none (no locks, no security)
• Custom (you can select the categories you want to block)

With OpenDNS browsing is faster because the servers are reserved for large amounts of memory for caching address : not having to query other DNS servers for each request received, reduces greatly the response time. More requests are always redirected to the server physically closest to you.

Another 'feature' is interesting Typo Correction feature when typing a wrong URL into your browser (eg writing http://wikipedia.ogr ) recognizes and corrects spelling error point to the correct domain.

If you are users of services like TinyUrl , know that here you can use the same solution, called Shortcut: In fact into your control panel (or dashboard) you will be able to set a few words as shortcuts to address more complex and difficult to store (eg . "mail" -> http://mail.google.com/mail).

For managers of small and medium networks is to facilitate a better service statistics , which helps to analyze the amount of requests made by users through graphs or tables of supporting with the ability to export all data to CSV (fields separated comma) or printable. The data collected are as follows:

1. Total DNS requests
2. Total Unique Domains
3. Total Unique IPs (useful for larger networks)
4. Requested Domains
5. Blocked domains Requested
6. Request Types (A, MX, PTR)

You can see the definitions to distinguish the nature of the requests submitted by your users during the analysis. Plus anytime you can reset all data and start over.

On page http://system.opendns.com (or http://208.67.219.60/ if you have problems of resolution) is always a page server monitoring, ofwhich five are living in America and one in London. The page includes the current status of servers, one of the last 30 days, some statistics on trends and the amount of DNS requests answered per day: very impressive at the time, both in numbers and in the absence of negative reports.

Why all this? What do we gain?

openDNS earns giving an error page containing relevant advertising every time you type an invalid address in your browser. When you offer and the service is very good and reliable you can also earn so little, for the happiness of all.

To use the service, I refer you to the instructions on the official page. You can also configure your router to automatically distribute the OpenDNS service via DHCP.

Updating

In the last hours The Pirate Bay has been release from seizure :-)

If you are having problems with the cancellation, alteration or moving files Excel files on your Windows server, typically with errors like this:

The file can not be deleted: It Is Being Used by Another person or program

and maybe the system is installed Viruscan McAfee Enterprise 8.0i with patch 16 (or 15 + HotFix 311933) does not know where to turn and your users want in the meantime hang from a pole may be interested in this Knowledge Base article that describes the problem on the same version and offers both a workaround that a decisive patch , a fix of the hotfix.

After installing the patch, reboot the server and the problem should be solved.

If for any reason at the moment you can update your Viruscan, McAfee recommends that you disable Opportunistic file locking , which allows the first client to lock a file in order to have exclusive access to a resource, to avoid loss of data if the same an application is modified by other concurrent clients.
