I have been testing various ways to read and write text files with GZIP in Python. There were a lot of uninteresting results, but there were two I thought were worth sharing.
If you have a big list of strings to write to a file, you might be tempted to do:
f = gzip.open(out_path, 'wb')
for line in lines:
| class TranslucentWin:NSWindow, NSApplicationDelegate, NSWindowDelegate{ | |
| /** | |
| * | |
| */ | |
| override init(contentRect: NSRect, styleMask aStyle: Int, backing bufferingType: NSBackingStoreType, `defer` flag: Bool) { | |
| super.init(contentRect: Win.sizeRect, styleMask: NSTitledWindowMask|NSResizableWindowMask|NSMiniaturizableWindowMask|NSClosableWindowMask|NSFullSizeContentViewWindowMask, backing: NSBackingStoreType.Buffered, `defer`: false) | |
| self.contentView!.wantsLayer = true;/*this can and is set in the view*/ | |
| self.backgroundColor = NSColor.greenColor().alpha(0.2) | |
| self.opaque = false | |
| self.makeKeyAndOrderFront(nil)//moves the window to the front |
| vec3 hsv2rgb(vec3 c) | |
| { | |
| vec4 K = vec4(1.0, 2.0 / 3.0, 1.0 / 3.0, 3.0); | |
| vec3 p = abs(fract(c.xxx + K.xyz) * 6.0 - K.www); | |
| return c.z * mix(K.xxx, clamp(p - K.xxx, 0.0, 1.0), c.y); | |
| } |
All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.
Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

#CMU Course Info 整理自一亩三分地
##08722 – Data Structurefor application programmers 这门课主要是开给EBIZ和MISM的，在MISM那边的课号是95772. 但是很多ECE, INI的同学，以及咱ME转CS帮都在上这门课。这门课只有半学期，一共6个credits，相当于1.5学分。内容非常基础，但是我觉得帮助挺大的，对于非CS科班出身想转CS的同学非常建议上一下， 基础越弱收获越大，要是基础比较硬的话就不用上了。LZ上的其它CS的课几乎都是各种牛校的PHD出身，这门课的老师好像都没有PHD学位，肯定没法去上15的课，但是讲课挺用心，讲的也很清楚。讲课这东西真的不是老师自己越牛就讲的越好。尤其数据结构这种比较基础的内容。这门课从最简单的内容讲起，包括array, arraylist, linked list, stack, queue,sorting(bubble, selection, insertion, merge, quick, heap), hashTable, hashMap,hashSet, BST, TreeMap, TreeSet, Huffman coding, Heap. 每周一次quiz, lab, homework。讲的时候内容都围绕Java Collection 来讲，还涉及与collection有关的comparator, iterator 等内容。这门课完全就是针对面试的，作业要求先手写代码（虽然大部分时候都是先ECLIPSE敲好再抄到纸上的）。
6次homework，前面的非常简单，后面稍微麻烦一点，难度都不大，就是让你去熟悉这些数据结构能自己implement，也能用JAVA COLLECTION。
