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).
É com orgulho que vejo o produto, nascido de muitos sacrifícios e preserverança de uma talentosa equipa, dar os merecidos frutos. O artigo no jornal Semana Informática é apenas mais uma prova disso.
We were present at TechDays 2008, proud to present our solution for Town Hall Meetings on the Innovation Spotlight event. It facilitates the decision-making process, providing full support for the meeting agenda creation and delivery, as well as for all the attached documentation. Hugo Vicente, one of our cherished co-workers, did a great job presenting it!
Have you ever questioned yourself how you could create a Sharepoint Solution Package and still don't know how to do it? Read this great article by Evgeny Tugarev.
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.
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? ; )
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 : )
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.
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.
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 :)
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.
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.
MyWebPages starter kit is a customizable dynamic content management system that you can use to learn how to deploy and maintain your websites (and in the process, a bit of ASP.Net and .Net languages also :).
Microsoft-DS (Microsoft Directory Services) is a port used for file sharing. It was introduced with Windows 2000 and gives you the possibility to use SMB protocol (stands for Server Message Block, but is also known as Samba) directly over TCP-IP on port 445.
