Just last week, the Document
Foundation rolled out LibreOffice 4.0. The updated version of the free open
source productivity suite promises a wide range of improvements, ranging from
enhanced compatibility with Office documents and document management systems to
small upgrades in Writer and Calc. Beyond these, however, LibreOffice 4.0's
significant improvements can be felt upon its thorough use and here are some
good reasons why it is worth the shot.Enhanced inoperability
The
engineers at Document Foundation put a whole lot of work in improving the
inoperability of LibreOffice 4.0. It now better supports Microsoft documents
formats, allowing the import of ink annotations from Word, inclusion of
comments to text ranges, and Microsoft Publisher layouts can now be opened in
Draw.
The
upgraded version now also supports checking documents from almost all document
libraries as long as they support CMIS open standard. These include IBM FileNet
P8, Visio, Microsoft Sharepoint 2010, Alfresco, Nuxeo, SAP NetWeaver Cloud
Service and OpentText.
Remote accessibility of presentations
Perhaps
one of the most promising features that LibreOffice 4.0 has is the Remote
Control App, which allows users to control their presentations from their
Android phones or notebooks over Bluetooth. Here, users can view slide
thumbnails, read speaker notes, and move to the next slide using the volume
control of their phones. According to Michael Meeks, developer of LibreOffice
and distinguished SUSE engineer, this simple addition is something that users
can utilize to carry out product or service demos at customer sites with great
ease.
Although
the feature is currently available for Linux users, Document Foundation assured
that in the next upgrade (which they promise will be released soon), the Remote
Control App can be supported on MacOS X and Windows.
Better-looking user interface
The interface
still has the usual menus, toolbars and icons. However, what makes the UI more
interesting is that it now supports Firefox themes, which means you can choose
from multiple icon sets or pick one from the thousands of personas available to
spiff up the interface. In addition, the Linux version integrates with the
Unity interface for GNOME. Other notable upgrades in the UI include Template
Manager dialog and the ability to preview fonts.
Faster reaction time
LibreOffice
4.0 is faster than its 3.5 version. There is a significant improvement in the
way it loads and saves different kinds of documents, but this is more
noticeable for larger .xls spreadsheets, .ods and .rtf files.
It is free
Of
course, the biggest draw about LibreOffice 4.0 (or LibreOffice in general) is
that you can get it for free. And since it is an open source solution, you have
the power to customize it according to your needs.
Although
LibreOffice 4.0 may not be as powerful as the other ones available as it has
areas that still needs tweaking, it cannot be denied that for a two-year old
office suite, it shows a lot of promise, especially now there is an influx of
developers who are working on providing neat improvements for the program.
Simply put, if you are looking for a free alternative to the usual expensive
office suites available, LibreOffice 4.0 is a smart choice.
Pronounced
yoo-niks, a popular multi-user, multi-tasking operating system developed in the
1960s at the bell laboratory. Created by just a handful of programmers, UNIX
was designed to be a small, flexible system used exclusively by programmers.
UNIX is a highly programmable language (an operating system) and still regarded
as one of the most powerful, versatile, and flexible operating system (OS) in
the computer world. UNIX Systems have Graphical User Interface (GUI) facility
like Microsoft Windows which to easy to use. The most famous varieties of UNIX
are Sun Solaris, GNU/Linux, and MacOS X.
It was designed
for a programmer not for a casual end-user. A programmer can easily operate
UNIX operating system.
Multi-tasking Facility
Many computers do
just only one thing at a time, as anyone who uses a PC or laptop can attest.
But, on the other hand, UNIX lets a computer do several things at once, such as
printing out one file while the user edits another file. This is a major
feature for users, since users don’t have to wait for one application to end
before starting another one.
Multi-user Facility
The computer can
take the commands of a number of users, determined by the design of the
computer to run programs, access files, and print documents at the same time.
This is the best facility of UNIX.
It has fast speed
with respect to others and it is mainly divided in three parts as follows -
1. The Kernel
2. The shell and
3. The programs
The Kernel
It controls the
hardware and turns part of the system on and off at the programmer’s command.
If you ask the computer to list all the files in a directory then, the kernel
tells the computer to read all the files in that directory from the disk and
display them on your screen.
The Shell
Shell is used to
act as an interpreter between the user and the computer as its purpose is same
like Kernel. There are several types of shell as most notably the command
driven Bourne Shell, the C Shell (no pun intended), and menu-driven shells that
make it easier for beginners to use.
The Programs
There are hundreds
of programs available to UNIX users. Typically, they are grouped into
categories for certain functions, such as word processing, business
applications, or programming.
The main features
of UNIX are—
• Multitasking
capability
• Multiuser
capability
• Portability
• UNIX programs
• Library of
application software
Finally, UNIX is
the best operating system, very admired as today it is using by billions of
peoples…
