gnome 自启动程序设置

呼...花了几个小时,终于弄明白了,没想到这个东西挺隐蔽而且网上基本搜不到...

以前我一直用~/.gnomerc,不过这个是在gdm刚加载时调用的,如果这个时候运行一个窗口程序,一开始会没有标题栏等等,挺不爽.

后来知道了可以用gnome-session-properties(System->Preferences->Sessions)来进行配置, 里面有个startup.

但是我想知道其具体配置文件在哪里,网上很多说在~/.gnome2/session,我看了,一开始没有这个文件,但是在gnome-session-properties里选择Save the current session后就有这个文件了.

如果这个文件不存在,gdm会找/usr/share/gnome/default.session

不过我觉得这个并不是我想要的,虽然也能起到自启动的效果. 因为它里面的内容和gnome-session-properties的startup配置并不符合.

最后花了九牛二虎之力找到了,在~/.config/autostart目录下,里面有若干.desktop文件. 虽然对其格式还不是非常了解,但是肯定这就是我要找的了.

呼...

Determine Perspective Lines With Off-page Vanishing Point

In perspective drawing, a vanishing point represents a group of parallel lines, in other words, a direction. For any point on the paper, if we want a line towards the same direction (in the 3d space), we simply draw a line through it and the vanishing point. But sometimes the vanishing point is too far away, such that it is outside the paper/canvas. In this example, we have a point P and two perspective lines L1 and L2. The vanishing point VP is naturally the intersection of L1 and L2. The task is to draw a line through P and VP, without having VP on the paper. I am aware of a few traditional solutions: 1. Use extra pieces of paper such that we can extend L1 and L2 until we see VP. 2. Draw everything in a smaller scale, such that we can see both P and VP on the paper. Draw the line and scale everything back. 3. Draw a perspective grid using the Brewer Method. #1 and #2 might be quite practical. #3 may not guarantee a solution, unless we can measure distances/p...

Chasing an IO Phantom

My home server has been weird since months ago, it just becomes unresponsive occassionally. It is annoying but it happens only rarely, so normally I'd just wait or reboot it. But weeks ago I decided to get to the bottom of it. What's Wrong My system set up is: Root: SSD, LUKS + LVM + Ext4 Data: HDD, LUKS + ZFS 16GB RAM + 1GB swap Rootless dockerd The system may become unresponsive, when the IO on HDD is persistantly high for a while. Also: Often kswapd0 has high CPU High IO on root fs (SSD) From dockerd and some containers RAM usage is high, swap usage is low It is very strange that IO on HDD can affect SSD. Note that when this happens, even stopping the IO on HDD does not always help. Usually restarting dockerd does not help, but rebooting helps. Investigation: Swap An obvious potential root cause is the swap. High CPU on kswapd0 usually means the free memory is low and the kernel is busy exchanging data between disk and swap. However, I tried the following steps, none of the...

Moving Items Along Bezier Curves with CSS Animation (Part 2: Time Warp)

This is a follow-up of my earlier article. I realized that there is another way of achieving the same effect. This article has lots of nice examples and explanations, the basic idea is to make very simple @keyframe rules, usually just a linear movement, then use timing function to distort the time, such that the motion path becomes the desired curve. I'd like to call it the "time warp" hack. Demo See the Pen Interactive cubic Bezier curve + CSS animation by Lu Wang ( @coolwanglu ) on CodePen . How does it work? Recall that a cubic Bezier curve is defined by this formula :

B (t) = (1 - t)^{3} P_{0} + 3 (1 - t)^{2} t P_{1} + 3 (1 - t) t^{2} P_{2} + t^{3} P_{3}, 0 \leq t \leq 1.

In the 2D case,

B (t)

has two coordinates,

x (t)

and

y (t)

. Define

x_{i}

to the be x coordinate of

P_{i}

, then we have:

x (t) = (1 - t)^{3} x_{0} + 3 (1 - t)^{2} t x_{1} + 3 (1 - t) t^{2} x_{2} + t^{3} x_{3}, 0 \leq t \leq 1.

So, for our animated element, we want to make sure that the x coordiante (i.e. the "left" CSS property) is \(...
