For those which have been using Java since its beginings, the jump from JDK 1.4 to JDK 5 was a big step.

One of the major changes were the introduction of Generics, a very powerful feature in my opinion.

Using them just to specify the type of the collections or list at compiling time is very simple, but when we start dealing with our own generic classes and methods, using wildcards and so on, it get’s much more complicated.

Brian Goetz from SUN microsystems, bring us a great tutorial divided in two parts, to fully understand the use of them and avoid getting stack on the road.

With only two days from its public release, TippingPoint’s Zero Day Initiative reported a critical vulnerability affecting Firefox 3.0 as well as 2.0 versions yesterday.

It’s unreleased and Mozilla is working on a fix already. Whatever the exploit is, it does require the user to visit a malicious site or click a link to executed. It came in 5 hours after the FF3 release, but since it affects previous versions, we wonder if the researcher was just sitting on it to be first. The Zero Day Initiative pays researchers for the exploits they submit.

Mozilla released Firefox 3 Release Candidate 1, which already have 33 months of development and whose final release doesn’t have a certain release date.

Some of the new features are:

• Javascript machine performance improvements. Applications like Google Mail and Zoho Office run twice faster than in Firefox 2.
• Better memory management thanks to new technologies.
• Bookmarks, history, cookies and user preferences are stored in a secure transaccional database, which will allow data loss in case of system failure.

I’ve been trying the earlier betas of Safari for Windows, but none of them have really conviced me at all, mainly because the majority of the websites I usually visit don’t look right.

Nevertheless, I downloaded and installed the new Apple Safari 3.1, and to be honest, it surprised me.

Unfortunately, it hangs up the first time I tried it.

Apart from that, then it works ok and there are some characteristics that really deserve some lines:

An interesting feature is Private Browsing. When activivated Safari doesn’t store Google’s search we made, cookies, history, downloads and forms data.

Another feature, maybe not very useful but different, is the possibility to change the size of the text areas. I haven’t seen this in other browsers.

The integrated RSS reader is quite good.

Searching text in a web page with Safari it’s very easy and clean. The search results are highlighted so you can find them quickly.

There are some other features that I haven’t tried yet, such as SnapBack, bookmarks handling Itunes style and the form autocomplete.

Anyway, I think that which brower is best than the other is a matter of how comfortable do you feel working with it or which is easier to use.
Personally, I use Firefox since its earlier releases, it seems to be fast, realible, it has the best tab browsing, although the memory use problem hasn’t be solved yet.
All in all, Apple Safari 3.1 has some innovations over the other competitors, but i think that it’s too much saying that is the best browser in the world, as Apple said.

Or maybe is beacuse of her?

If you migrate from SQL Server 2000 to SQL Server 2005, probably the database indexes had to be rebuild again.
This is the script to do that:

USE database_name
GO
EXEC sp_MSforeachtable @command1=”print ‘?’ DBCC DBREINDEX (‘?’, ‘ ‘, 80)”
GO
EXEC sp_updatestats
GO
