What is Varkon ?VARKON can be used as a traditional CAD-system with drafting, modelling and visualization if you want to but the real power of VARKON is in parametric modelling and CAD applications development. VARKON includes interactive parametric modelling in 2D or 3D but also the unique MBS programming language integrated in the graphical environment. The system was originally developed by a group lead by Dr. Johan Kjellander at the University of Linkoping in Sweden. In 1985 he founded Microform and Varkon became a commersial product. Varkon was marketed and further developed until year 2000 when Dr. Kjellander left Microform to lead the CAD research group at the University of ?rebro. The sources were then released under the GNU/GPL license and the CAD research group became the maintainers of the system. In august 2007 the Varkon project moved to the SourceForge web. See: http://www.sourceforge.net/projects/varkon where it is still maintained by the members of the CAD research group at the university in ?rebro. VARKON is written in ANSI portable C and has been compiled and successfully executed on many different platforms. The UNIX version has a user interface based on X-Windows/OpenGL and the PC version uses Microsoft WIN32/OpenGL. Prebuilt binaries are available for Linux and Microsoft windows.
Some things you can do with VARKON.VARKON is used to develop and run applications. An application is a VARKON system that's been modified and extended with knowledge and functionality specific to a certain product or problem. VARKON applications can perform any calculations, retrieve data from external databases, make decisions, perform complex geometrical operations, build object oriented structures with attributes and geometry, generate graphic images like 2D drawings or 3D models with shading or hidden lines removed and create any type of datafiles with output of your own choice. VARKON is ideally suited for all types of variational design. Wooden houses, tools for ballbearings, welded steel parts or electrical installations are some of the products currently designed in VARKON using this technique. In variational design the actual design work is often reduced to a few percent of the time spent with traditional methods. Using VARKON with its unique ability to handle geometry as well as other features and store the result in a well structured and object oriented manner it is also easy to produce much more information than paper drawings. Cost estimations, bill of materials and different forms of manufacturing data are usually created automatically in VARKON applications. VARKON is easy to integrate. A VARKON application can communicate using files or pipes and can spawn other processes as well as being spawned itself. Using this technique you can either let a VARKON application be on top and control other systems or you can use other systems to control VARKON. Varkon also includes an ODBC API for communication with commersial databases. VARKON is a powerful geometric modeller. Basic 3D entities are points, lines, arcs, curves, surfaces, coordinate systems and transformations. Several representations of parametric curves are implemented including rational polynomial, analytical offset and curves on surfaces so called UV-curves. Surface representations include rational polynomial, lofted procedural, analytical offset and a faceted surface for approximations. Basic support for trimmed surfaces was introduced in Varkon version 1.19. Operations include intersects, closest point, silhouette, curvatures, transformation, trimming, export, import and approximation. Basic visualization as well as complex rendering based on OpenGL is included in all versions of the system. A key feature in all modeling is the capability to record not only the results of interactive operations but also the operations history, making it possible to go back and inspect what you have done, then change something and automatically update the model. Being a fully generic system this is standard behavior in VARKON. All interactive operations are automatically recorded as MBS-statements and the model can any time be edited using the MBS-editor instead of interactive graphics if this is preferred. Using MBS your own design rules or constraints can easily be linked into the model. Such changes are automatically compiled and the result shown immediately on the screen.
Two things you can't do.VARKON is not a true solid modeller. VARKON surfaces can be trimmed and faceted and images can be produced with shading or hidden lines removed but mass properties like volume or center of gravity can not be calculated automatically. This doesn't mean you cant use VARKON in applications where weight or volume is important. It only means you will have to deal with the problem in other (maybe less automatic) ways. VARKON is not a manufacturing (CAM) system. There are no high level functions in VARKON to support the programming of multi axis numerical machines. You can create your geometry in VARKON but multi axis machine programming will have to be done using other software. For less complicated manufacturing processes though it can surprisingly often be worth the effort to let VARKON applications generate numerical control data automatically even if this means extra programming in MBS initially.

An introduction to Ubuntu
An introduction to Ubuntu:
Ubuntu is “Linux for human beings”, a complete open-source operating system which aims to make Linux simple and a solid option for everyday desktop use. It includes common applications such as a web browser, e-mail client, and a complete office suite that is compatible with Microsoft Office and other document formats, such as the new ODF standard, the rapidly growing standardized format for the future of office documents.
Ubuntu is available completely free of charge, in keeping with the founding principles of the Ubuntu distribution. Ubuntu's active, growing community is one of the core aspects of Ubuntu, with users participating in such ways as providing free support for others, exchanging ideas and suggestions, and developing software, all as volunteers.
Ubuntu is much more stable and less prone to security holes, viruses, and spyware than Windows due to a different security model, is entirely themable and customizable to fit your needs and preferences, and has huge quantities of software available to go with it, all easily accessible and free. Many of these applications, including the office suite, are even available for Windows, so you can comfortably use the same thing on both systems.
You don't have to give up everything you know and jump in headfirst. Ubuntu's Live CD lets you run Ubuntu entirely off a CD without touching your existing Microsoft Windows or Mac OS X installation at all, with no risk of losing data or breaking the existing installation. You can even install Ubuntu without erasing your other operating system, in a “dual-boot” configuration which allows you to simply choose which one to use when you start the computer and share files between the two systems.
Ubuntu is also available with multiple “graphical environments”, that can each be further customized, since everybody has different tastes for the “look and feel” they're comfortable with. Disks are available today with one called “Gnome” as well as “KDE”, so you can try either of those, and if you'd like to take a look at others (like XFCE), screenshots of all versions (called Ubuntu, Kubuntu, Xubuntu, and one even specially tailored towards use with children and schools called Edubuntu) are available at http://shots.osdir.com/.
These CDs are from the 7.04 (April 2007) release and being given to you to make Ubuntu available to people who might otherwise not have been aware of its existence, or of free software in general. Open-source projects such as Ubuntu develop at a rapid pace, so exciting improvements and new features are always becoming available, so watch for future releases too, with the next one coming up this October.
So, feel free to pop the CD in and reboot into the Live environment to check it out. If it doesn't really appeal to you, or you choose one graphical environment over another, please pass unused CDs on to a friend, relative, or coworker you think might be interested or leave it somewhere, like the break room at work perhaps. If you like what you see, just click the “Install” icon on the desktop and enjoy!
The current release supports PC (Intel x86), 64-bit PC (AMD64), PowerPC (Apple iBook and Powerbook, G4 and G5), and Sun UltraSPARC architectures, so if you need a different CD, you can download them [http://www.ubuntu.com/download] or get some shipped for free [https://shipit.ubuntu.com/].

Introducing the Hardy Heron
Hi Folks,
I am delighted to have the pleasure of announcing the Hardy Heron
(Ubuntu 8.04), the next version of Ubuntu that will succeed Gutsy Gibbon
(Ubuntu 7.10, due for release in October 2007). Not only will the Ubuntu
community continue to do what it does best, produce an easy-to-use,
reliable, free software platform, but this release will proudly wear the
badge of Long Term Support (LTS) and be supported with security updates
for five years on the server and three years on the desktop. We look
forward to releasing the Hardy Heron in April 2008.
With the opening of each new release cycle of Ubuntu, we have more and
more opportunity at our fingertips. Not only are our friends in the
upstream world constantly innovating and extending their applications
and software, but the Ubuntu community continues to see incredible
growth in its diverse range of areas such as packaging, development,
documentation, quality assurance, translations, LoCo teams and more.
Each new release gives us all an opportunity to shine, irrespective of
which bricks in the project we are laying, and this is at the heart of
our belief - working together to produce an Operating System that will
empower its users and shape the IT industry, putting free software at
the corner-stone of our direction.
Most people only ever see the end-user view of Ubuntu, running it on
their desktops, servers and mobile devices around the world. For these
users, Ubuntu provides a simple, convenient means to do what they want
to do easily, effectively and without unnecessary complexity. For many
of us though, we want to open up the hood and understand how the system
works and how to extend and grow it. Thousands of us get out of bed
every day, united behind Ubuntu, ready to make a difference, working
together to make our vision happen.
Importantly, our ethos of collaboration and freedom extends to the
development process as well as the end product. As such, the Ubuntu
development process is a very open, transparent one, and anyone is
welcome to get involved. It works like this:
- Everyone is welcome to think of and develop ideas for features that
could be present in the Hardy Heron release. These ideas are written as
specifications (detailed documents outlining how the idea would work and
be implemented). You are welcome to add your specifications to
https://blueprints.launchpad.net/ubuntu.
- In October 2007, we will hold the Ubuntu Developer Summit in
Cambridge, Massachusetts, USA and generate a schedule of sessions to
discuss these specifications. The sessions provide a means for
interested parties to help scope out the proposed feature and determine
methods and plans to implement it. The Ubuntu Developer Summit is a
semi-virtual event in which those who cannot attend can dial in with
VoIP and use IRC and collaborative editing with Gobby to take part in
the summit.
Everyone is welcome to participate, everyone is welcome to get involved,
and everyone is welcome to help shape the form of the Hardy Heron. Let's
work together to shake things up, make things happen and make the most
compelling Ubuntu release yet. Start your engines...

methods and plans to implement it. The Ubuntu Developer Summit is a
semi-virtual event in which those who cannot attend can dial in with
VoIP and use IRC and collaborative editing with Gobby to take part in
the summit.
Everyone is welcome to participate, everyone is welcome to get involved,
and everyone is welcome to help shape the form of the Hardy Heron. Let's
work together to shake things up, make things happen and make the most
compelling Ubuntu release yet. Start your engines...
I am delighted to have the pleasure of announcing the Hardy Heron
(Ubuntu 8.04), the next version of Ubuntu that will succeed Gutsy Gibbon
(Ubuntu 7.10, due for release in October 2007). Not only will the Ubuntu
community continue to do what it does best, produce an easy-to-use,
reliable, free software platform, but this release will proudly wear the
badge of Long Term Support (LTS) and be supported with security updates
for five years on the server and three years on the desktop. We look
forward to releasing the Hardy Heron in April 2008.
With the opening of each new release cycle of Ubuntu, we have more and
more opportunity at our fingertips. Not only are our friends in the
upstream world constantly innovating and extending their applications
and software, but the Ubuntu community continues to see incredible
growth in its diverse range of areas such as packaging, development,
documentation, quality assurance, translations, LoCo teams and more.
Each new release gives us all an opportunity to shine, irrespective of
which bricks in the project we are laying, and this is at the heart of
our belief - working together to produce an Operating System that will
empower its users and shape the IT industry, putting free software at
the corner-stone of our direction.
Most people only ever see the end-user view of Ubuntu, running it on
their desktops, servers and mobile devices around the world. For these
users, Ubuntu provides a simple, convenient means to do what they want
to do easily, effectively and without unnecessary complexity. For many
of us though, we want to open up the hood and understand how the system
works and how to extend and grow it. Thousands of us get out of bed
every day, united behind Ubuntu, ready to make a difference, working
together to make our vision happen.
Importantly, our ethos of collaboration and freedom extends to the
development process as well as the end product. As such, the Ubuntu
development process is a very open, transparent one, and anyone is
welcome to get involved. It works like this:
- Everyone is welcome to think of and develop ideas for features that
could be present in the Hardy Heron release. These ideas are written as
specifications (detailed documents outlining how the idea would work and
be implemented). You are welcome to add your specifications to
https://blueprints.launchpad.net/ubuntu.
- In October 2007, we will hold the Ubuntu Developer Summit in
Cambridge, Massachusetts, USA and generate a schedule of sessions to
discuss these specifications. The sessions provide a means for
interested parties to help scope out the proposed feature and determine
methods and plans to implement it. The Ubuntu Developer Summit is a
semi-virtual event in which those who cannot attend can dial in with
VoIP and use IRC and collaborative editing with Gobby to take part in
the summit.
Everyone is welcome to participate, everyone is welcome to get involved,
and everyone is welcome to help shape the form of the Hardy Heron. Let's
work together to shake things up, make things happen and make the most
compelling Ubuntu release yet. Start your engines...

人最多的一次
国庆回来后，我就在想什么时候去爬山呢，去完成自己定下的一周去一次的目标。
定一个目标容易，坚持下来太不容易了，就像让你把1+1＝2每天在本子算10遍一样简单的事，能坚持一个月也不简单了。
昨天T问起我，这周还去不去爬山。
我也怕自己坚持不下来，我看到天气预报说周六和周日有雨的，有雨可能就去不了了，昨天下午和晚上又要上课。
早上起来看窗户外面，昨天晚上还真下雨了，早上雨停了。
上午四节课要上，当然不能去了。抓紧时间联系人，下午去，第一节下课在教室找了几个人，今天大家答应的还比较快，想出去走走。一共五个人，说好中午1点到东门****。
中午的时候，除了LFZH因为女朋友过来了要陪，其余四人1点都按时到了东门。
四个人：WZHSH、LWY、CHH
没有什么说的，出发了。考虑到天气的关系，这周应该去中山陵了。这是人最多的一次了，本来想去紫金山的，考虑到天气的原因，就去了中山陵。老****下走了一次，回来时想换个新线路走走，就走了明孝陵那条路。
四个人对那里的路都不太熟悉，就随意走吧，到了明孝陵进去参观了下，以前去过的W、CH说现在这里新装修后没有以前那种感觉了，至于是什么感觉，我以前没有去过，现在也没有想得太明白。
在明孝陵参观的时候，L一直提醒我要看那面墙上的字。上去的时候我就专门注意了下，原来是“此山为明太祖安之墓”，呵呵，一个山？
因为下起了小雨，我们就没有上那“山”顶，到了城墙我们就下来了，城墙上面也有个像四方城那样的一个方形的“城堡”。就是少了石碑，听说这当初为了显示孝心，把石碑尽量做大，大的不能移动了，所以就没有放上来。
呵呵

随便写些
一周没有上QQ空间了，也没有来更新下日志。
这一周一直在UBUNTU系统下，没有启动过WINDOWS系统。马化腾设计的这个QQ不仅没有LINUX版的，而且还经常把LINUX自己开发的软件给封掉。
只要在UBUNTU下就没有办法上空间，没有办法用QQ语音和视频，不知道责任在谁呢？虽然我用的不是盗版的WINDOWS，但用UBUNTU的舒心，快速已经让我很少去启动WINDOWS了。
现在记些自己的事情，写些自己的心情，希望QQ的空间不会像传说中的那样要收费。
上周申请了个MSN，一直在MSN上和好友联系。就一个原因，MSN在UBUNTU下用着没有限制。
以前听说QQ只是人小时候的一个玩具，大了之后就不会再用了。但现在这个玩具已经发展得让你离不开它，因为和很多朋友的联系都在QQ上面，国内也开发了不少即时通信软件，但没有一个能竞争过QQ的。
我的MSN：[email=yunfan_1982@hotmail.com]yunfan_1982@hotmail.com[/email]
不说了，按自己喜欢的方式去生活吧！
