About the Copyright

      我在八月份的时候写过一篇技术文章,题目为《关于短信内容格式及压缩方法》,昨天上网无意在baidu上搜索,竞然搜到自己的文章,但是令人有点不爽的是文章被某个汇编语言网站转载了排在了baidu的第一位,但没有注明出处。用‘短信内容格式’在baidu上搜就可以搜到,我觉得转载应该注明作者及出处才对。不过我在网上写技术文章,本着以开放的心态,就是为了让更多人看到,这一点本不与初衷违背,小小牢骚一下。
      以后写blog还要注意一点,在网络的大环境中保护自己,google一个工程师就是因为写blog被开除。不过我写的东西都是规范里所规定的东西,不存在什么秘密,不会有什么问题,况且我写的东西少,其实我在研发的时候发现有很多的技术牛人,他们很少写东西,甚至项目文档都懒得写,有点大隐隐于市的味道,写技术文章有利于自己更好地理解技术,所以是一件大大的好事,我认为。
     短信内容及压缩方法是根据在研发所做的具体项目写的一篇文章,对COS打补丁修改了短信的格式,根据短信规范,打补丁是全汇编实现,连续几天加班,最后所做的项目第二天就要去国密办去测试了,那天晚上加班到凌晨四点多,把代码及相应的东西发给了要去测试的人,然后回家睡觉,基本上连续干二十个小时,丝毫没有倦意。我觉得这种状态只有在特定的环境下才可以出现,有时候对工作的激情是旁人无法想象的,虽然这不是一个正常状态,但是它有时候让人迷恋,我发现我对工作的激情正在消退,好事还是坏事?呵呵。
wall attribute command Syntax wall attribute <facet> <vertex> keyword ... <range> Primary keywords: centrotation | conveyor | cutoffang | displacement | euler | fragment | position | spin | velocity | xcentrotation | xconveyor | xdisplacement | xeuler | xposition | xspin | xvelocity | ycentrotation | yconveyor | ydisplacement | yeuler | yposition | yspin | yvelocity | zcentrotation | zconveyor | zdisplacement | zeuler | zposition | zspin | zvelocity Set the value of wall attributes. This command is a synonym for the wall initialize command. Individual attributes can be listed with the wall list command and all attributes can be visualized. The optional vertex kewyord can be used to with the velocity, xvelocity, yvelocity, or zvelocity keywords to set the vertex velocities for vertices in the specified range. The optional facet keyword can be used with the conveyor, xconveyor, yconveyor, or zconveyor keywords to set the facet conveyor velocities for facets in the specified range. centrotation vcen Set the center of rotation for walls in the range. This is the position about which rotations occur when an angular velocity is supplied to a wall. The center of rotation translates with the wall if a translational velocity is supplied. The default center of rotation is the origin. conveyor vconcvel Set the facet conveyor velocity vector. If given with the facet keyword, then the range applies to facets. Otherwise the conveyor velocity is set for all facets in each wall in the specified range. The conveyor velocity is a fictitious velocity that is added to the wall velocity when calculating the relative velocity between a facet and another piece. A conveyor velocity cannot be active when vertex velocities are active. Setting a nonzero conveyor velocity allows one to simulate conveyance of balls or clumps along facets without moving the facets. cutoffang fang Set the cutoff angle (an angle in degrees) for walls. By default, the cutoff angle is 0. This angle controls contact state information propagation. displacement vdisp Accumulated wall displacement vector as a result of cycling. euler veuler (3D ONLY) Current orientation of Euler angles following the X,Y,Z convention (e.g., rotation about the x-axis followed by rotation about the y'-axis followed by rotation about the z''-axis) in degrees. The orientation is updated only when orientation tracking has been enabled (see set orientation command). When active, the current clump orientation can be visualized. fragment i Fragment ID (see "Fragment"). position vpos Wall location vector. This corresponds to the average position of all vertices. The center of rotation is not modified. spin fspin fspiny fspinz (y- and z- components are 3D ONLY) The wall angular velocity in radians per second. Walls rotate around their center of rotation. velocity vel Wall translational velocity vector. If given with the vertex keyword, then this corresponds to the vertex velocity and the range applies to vertices. xcentrotation fcenx Set the x-component of the center of rotation for walls in the range. This is the position about which rotations occur when an angular velocity is supplied to a wall. The center of rotation translates with the wall if a translational velocity is supplied. The default center of rotation is the origin. xconveyor fconcvelx Set the x-component of the facet conveyor velocity. If given with the facet keyword, then the range applies to facets. Otherwise the conveyor velocity is set for all facets in each wall in the specified range. The conveyor velocity is a fictitious velocity that is added to the wall velocity when calculating the relative velocity between a facet and another piece. A conveyor velocity cannot be active when vertex velocities are active. Setting a nonzero conveyor velocity allows one to simulate conveyance of balls or clumps along facets without moving the facets. xdisplacement fdispx The x-component of the accumulated wall displacement as a result of cycling. xeuler feulerx (3D ONLY) The x-euler angle (in degrees) of the current wall orientation. See the euler keyword for further details. xposition fposx The x-component of the wall location. This corresponds to the average position of all vertices. The center of rotation is not modified. xspin fspinx (3D ONLY) The x-component of the wall angular velocity in radians per second. Walls rotate around their center of rotation. xvelocity fvelx The x-component of the wall translational velocity. If given with the vertex keyword, then this corresponds to the x-component of the vertex velocity and the range applies to vertices. ycentrotation fceny Set the y-component of the center of rotation for walls in the range. This is the position about which rotations occur when an angular velocity is supplied to a wall. The center of rotation translates with the wall if a translational velocity is supplied. The default center of rotation is the origin. yconveyor fconcvely Set the y-component of the facet conveyor velocity. If given with the facet keyword, then the range applies to facets. Otherwise the conveyor velocity is set for all facets in each wall in the specified range. The conveyor velocity is a fictitious velocity that is added to the wall velocity when calculating the relative velocity between a facet and another piece. A conveyor velocity cannot be active when vertex velocities are active. Setting a nonzero conveyor velocity allows one to simulate conveyance of balls or clumps along facets without moving the facets. ydisplacement fdispy The y-component of the accumulated wall displacement as a result of cycling. yeuler feulery (3D ONLY) The y-euler angle (in degrees) of the current wall orientation. See the euler keyword for further details. yposition fposy The y-component of the wall location. This corresponds to the average position of all vertices. The center of rotation is not modified. yspin fspiny (3D ONLY) The y-component of the wall angular velocity in radians per second. Walls rotate around their center of rotation. yvelocity fvely The y-component of the wall translational velocity. If given with the vertex keyword, then this corresponds to the y-component of the vertex velocity and the range applies to vertices. zcentrotation fcenz (3D ONLY) Set the z-component of the center of rotation for walls in the range. This is the position about which rotations occur when an angular velocity is supplied to a wall. The center of rotation translates with the wall if a translational velocity is supplied. The default center of rotation is the origin. zconveyor fconcvelz (3D ONLY) Set the z-component of the facet conveyor velocity. If given with the facet keyword, then the range applies to facets. Otherwise the conveyor velocity is set for all facets in each wall in the specified range. The conveyor velocity is a fictitious velocity that is added to the wall velocity when calculating the relative velocity between a facet and another piece. A conveyor velocity cannot be active when vertex velocities are active. Setting a nonzero conveyor velocity allows one to simulate conveyance of balls or clumps along facets without moving the facets. zdisplacement fdispz (3D ONLY) The z-component of the accumulated wall displacement as a result of cycling. zeuler feulerz (3D ONLY) The z-euler angle (in degrees) of the current wall orientation. See the euler keyword for further details. zposition fposz (3D ONLY) The z-component of the wall location. This corresponds to the average position of all vertices. The center of rotation is not modified. zspin fspinz (3D ONLY) The z-component of the wall angular velocity in radians per second. Walls rotate around their center of rotation. zvelocity fvelz (3D ONLY) The z-component of the wall translational velocity. If given with the vertex keyword, then this corresponds to the z-component of the vertex velocity and the range applies to vertices.
