无flash收听sky.fm | Listen to sky.fm without a flash player

sky.fm是我的最爱，原来ios有个sky.fm app，但是现在连不上了。

sky.fm现在也提供非flash的播放link，但是要进入那个flash页面，然而在ipad的safari上就会蹦到安装flash player的页面，很恶心。

当然如果有别的电脑可以去把link拷过来，但是没有。

于是搜了半天，发现了sky.fm/mobile。很好用，safari会自动调用quicktime，放后台也ok。

Sky.fm is my favorite online radio, there's been a sky.fm app on ios, but has been not working these days.

Non-flash links are also provided by sky.fm, however you'll need to visit the flash player page first, then get the links. While doing this with safari on ipad, you'll be redirect to a page which asks you to install flash player.

Of course, I can get the links from another computer, but there is not such another computer.

So I googled for a while, until I found sky.fm/mobile. Quite useful, since safari would call quicktime to play the list, so I can even listen to it putting it into background.

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 \(...
