The Latest Version of Apache Lucene Search Engine

Filed under Technology

Apache Lucene is the highest performing, full-featured text search engine library that has been completely written entirely in Java. It is currently in use by many large organizations since it is a technology that has been developed suitable for nearly any application that requires full-text search, especially across platforms. Apache Lucene is an open source project available for free download from their websites.

Lucene usually plans events to commemorate a particular release. The last release was in September 2009, where many new features were introduced to users. Some of the improvements are per segment searching and caching, near real-time search capabilities added to IndexWriter, new query types and smarter and more scalable multi-term queries (wildcard, range, etc).

Some of the other new features included last time were a freshly optimized collector/scorer API, improved unicode support, a new attribute based TokenStream API, and a new QueryParser framework in contribution with a core QueryParser replacement included.

Analyzers like PersianAnalyzer, ArabicAnalyzer and SmartChineseAnalyzer were new capabilities that were added to the existing ones. A new fast-vector-highlighter for large documents was also included in the release.

The new Lucene version included high-performance handling of numeric fields. The fields are indexed with a tree structure, making simple to use and faster numeric range searching without having to externally pre-process numeric values into textual values.

In November 2009, another major event has been planned which includes two full days of talks, plus a meet up and the usual bevy of training that is usually conducted by the teams across many cities in the US.

With Lucene and Solr going ahead and building new technologies for enterprise search, the economical benefits realized through their usage is also increasing. Lucene powers searches in areas like discussion groups, commercial issue trackers and in email searches. It is used by many Fortune 100 companies including Microsoft, Akamai, Overture, Technorati, HotJobs, Epiphany, FedEx, Mayo Clinic, MIT, New Scientist Magazine, and many others.

Lucene search application and Solr download can be made from Lucene home page.

Win32 Viruses – What Are They And Where Do They Come From?

Filed under Computers

This virus was started in 2005, so as viruses go they are quite old, they enter your system on an incoming mail with an attached. Exe file. If you open this file, it activates the virus and while it does not actually harm your data or computer they are not good to have. No virus is and it should be removed. This can be done manually or with anti virus tools.

This little bug first came to light in 2005 and when it come in on an ingoing email it shows as an. Exe file. The virus is activated when the. Exe file is opened, but it actually does no harm to your computer, and it also doesn't harm you information. It is easily and simply removed manually by using anti-virus software.

Otherwise known as the HAPP99. EXE, this is one of the Win32 Trojans. It has an inoffensive enough harm and after all it only causes a fireworks display. It spreads really quickly by people who don't know they are sending it and by the same token, it is highly unlikely you will know that you are sending it to someone else.

"SKA. EXE" is a copy of the virus and "SKA. DLL" is the modification file. This is the one that is going to modify one of your existing files. The existing file is "WSOCK32. DLL' and after modification it becomes "WSOCK32. SKA" and it is this that allows the sneaky attachment of HAPPY99. EXE to invisibly attach to your outgoing emails.

This virus is sneaky, but it does not do the same kind of damage that other Trojans do. For example it will not destroy any programs or crash your computer, and it will also not steal any of your private information. However it is still not wise to have any virus on your computer and this one can overload a server. This happens if it attaches itself to too many emails consecutively.

There is also the probability that other viruses will attach to the Win32. This is when some real problems can be experienced. It happens easily as Win32 gets passed around a great deal without anyone knowing.

Manual removal of Win32 through DOS is relatively simple. There must be some of you out there who remember DOS? Firstly, you know if your computer has the virus if you see a lovely fireworks display when you send an email. Getting rid of it is just a matter of finding it and making it ineffective. That way, you can't be responsible for infecting any other computers.

If a more dangerous third party virus manages to attach itself to Win32, it can become extremely dangerous. Information can be compromised and mutations occur, meaning more harmful threats, so it is best to get rid of it asap.

Remove win32 vundo is important to make sure that your computer is running well.
