(.hk) é o domínio mais perigoso da Internet

Thu, 05 Jun 2008 09:39:56 GMT

Um estudo levado a cabo pela McAfee, intitulado “Mapping the Mal Web Revisited”, revelou que Hong Kong é o país com o domínio mais perigoso (.hk) e a Finlândia como o mais seguro.

O domínio de Hong Kong (.hk) é considerado o local mais perigoso para navegar e pesquisar na Web, de acordo com um novo estudo da McAfee intitulado “Mapping the Mal Web Revisited”.

O segundo estudo anual da McAfee sobre os locais na Web mais perigosos e mais seguros revelou que 19,2% de todos os websites que terminam no domínio (.hk) constituem uma ameaça de segurança para os cibernautas.

A China (.cn) segue em segundo lugar no ranking com mais de 11%. No lado oposto, a Finlândia (.fi) substitui a Irlanda (.ie) como o domínio mais seguro com 0,05%, seguida do Japão (.jp).

O domínio genérico mais perigoso no estudo de 2007 mantém-se em 2008, com 11,8% de todos os websites terminados em (.info) a constituírem uma ameaça de segurança, e a representarem o terceiro domínio mais perigoso em termos gerais, enquanto os websites governamentais (.gov) permanecem como o domínio genérico mais seguro. O domínio mais comum (.com) é o nono domínio mais perigoso em termos gerais.

Utilizando a premiada tecnologia do McAfee® SiteAdvisor®, a McAfee analisou 9,9 milhões de websites fortemente visitados, provenientes de 265 domínios diferentes por país (por exemplo, websites terminados em (.pt) correspondentes a Portugal) e genéricos (por exemplo, websites terminados em (.net) ou (.info).

SkyDriving

Fri, 29 Feb 2008 09:21:31 GMT

Hello everyone! Long time, no see...

Last week, SkyDrive team has lauched the last version of their application and it brings some new features:

we now have 5Gb of available storing space;
it is available on 38 countries. Previously it was only available on Great Britain, India and U.S. (see this article last paragraph);
bug fixes and improvements to make the site faster and more reliable.

SkyDrive works just as a remote hard drive (for all those who doesn't know it). You have private and public folders and you can do most of the known file operations, even those related to security (users management and permissions).

Of course, the wonderfull thing about it is that it is accessed from any location where a web connection is available. You should try it...

Countries where SkyDrive is available: Argentina, Australia, Austria, Belgium, Bolivia, Brazil, Canada, Chile, Colombia, Denmark, the Dominican Republic, Ecuador, El Salvador, Finland, France, Guatemala, Honduras, Italy, Japan, Mexico, the Netherlands, New Zealand, Nicaragua, Norway, Panama, Paraguay, Peru, Puerto Rico, Portugal, South Korea, Spain, Sweden, Switzerland, Taiwan, and Turkey.

The beauty of the ?? operator

Mon, 20 Aug 2007 14:41:01 GMT

One of the not so known operator in C# is the ?? operator, but it's a very usefull one. If you're working with null values you'll want to work with this operator for sure...

Observe the following code block:

int? x = null;
int y = x;

This will go BOOM with an exception at compile time, but if you do something like this:

int y = x ?? -1;

It'll accept the -1 in case x is null (and doesn't explode). Usefull isn't it? ; )

Check this for more...

Concatenating data from fields

Wed, 11 Apr 2007 17:06:50 GMT

This piece of code is to all those who scratch their heads thinking about how to do some things in SQL... things that are done in a simple and intuitive way with high level languages. But don't despair! SQL is simple enough, including its syntax. All we have to do is go around some things that are more intuitive in other languages, but as a colleague of mine says: "We can do everything with SQL! All we have to do is to achieve a certain feeling about doing things with it"... and I agree : )

So will you : )

DECLARE @parametros varchar(150)
DECLARE @separador char

SET @separador = ','

SELECT @parametros = COALESCE(@parametros + @separador, '') + CAST(parametro AS varchar(5)) FROM tParametros
SELECT @parametros

Getting last day of a month

Wed, 11 Apr 2007 16:07:43 GMT

Here's a string to get the last day of a month:
SELECT DAY(DATEADD(d, -DAY(DATEADD(m,1,GETDATE())),DATEADD(m,1,GETDATE())))

Can you return true?

Tue, 13 Feb 2007 20:19:03 GMT

I banged and banged with my head against the wall after browsing the net for clues without any luck... but I'll start from the beginning...

I have an ASP.Net FileUpload control [ <asp:fileupload> ] in a gridview (what was I thinking... : ).
Although I had the control found and processed on code-behind, one sole method insisted on returning the value 'false'. It was the HasFile method, wich was... well... WRONG! Nothing I did returned differently until I tried a simple line instead: fileUpload1.PostedFile.ContentLength > 0.

So my happy code looks now like this:

FileUpload fileUpload1 = (FileUpload) GridView1.Rows[0].Cells[0].FindControl("Field1");
if(fileUpload1.PostedFile.ContentLength > 0)
{
bla, bla, bla...
}
else
{
bla, bla, bla somemore
}

...and it works just fine!

Hope this helps others : )

Cheers

Application Offline

Thu, 21 Dec 2006 12:23:38 GMT

If you ever need to take down your .Net web application to make big changes or other immense time-consuming tasks you can use the magical app_offline.htm file. Essentially this file will allow to shut down your application, unload its domain from the server, stop incoming request processing and present a nice self-made page to every person trying to hit your application.

All you have to do is to create the file and place it at the web application root directory when needed.

To know more about this read ScottGu's article.

.Net Remoting vs. XML Web Services

Wed, 20 Dec 2006 10:09:44 GMT

Do you know what are .Net Remoting and XML Webservices? Do you know how to choose between the two when needed or how to create them? Just read this article by Thiru Thangarathinam. It's quite enlightening :)

Convert, convert, convert...

Tue, 19 Dec 2006 10:36:10 GMT

Do you have Windows XP? Do you have the FAT32 system installed in your computer? Do you want to convert the file system to NTFS and don't know how? You can do this by simply using the DOS Shell.

Just open the Start menu and choose the Run command;
Type cmd and ENTER;
You're now at the wonderfull Shell of Os... at the prompt, type CONVERT drive_letter /fs:ntfs (example: CONVERT d: /fs:ntfs) et voila! You've initiated the conversion adventure.

This isn't always a straight forward action, but you should get to the end in safety, although my advice to you: is backup your data before you do this and, just in case, have your Windows XP CD at hand if needed : )

If you have a partition with no system installed and want to be a bit more extreme, just backup your data and format the drive with the NTFS system.

Leaking firewalls

Sat, 09 Dec 2006 00:40:59 GMT

How many of us have already installed a firewall more than once? How many try to find the perfect One?

Well... the bad news are nothing's perfect! The good news are there's some non-payed mean firewalls! Even better than some of their payed counter-parts! At least, these are the conclusions of a leaking test described at Techworld.com. You can see the test details and results (and even download them) at Matousec.com.

We have two winners classified as 'Excelent' and two other classified as 'Very Good' among 21 products. The first are Comodo Personal Firewall v2.3 and Jetico Personal Firewall v2.0 beta. The second are the aclaimed Zone Alarm Pro 6.5 and Trend Micro PC-cillin Internet Security 2007.

Other three are classified as 'Good' and the remaining 14 as 'Poor', 'Very Poor' or having no ability to resist the test whatsoever.

We never loose nothing by trying and testing... :)
