in 0.8.1, but to 1.2.0 still not as the default option. Hash Based Shuffle If you modify the logic for sort, the so-called improvements may affect the original spark application that is already stable. For example, an application that uses hash Based shuffle performance is exactly what is expected, so after migrating to spark 1.2.0, you only need to modify the configuration file below to complete this seamless migration. As a common computing platform, your test case will never cover al

take a shortcut. If you are fast into JavaScript practice, you will eventually need more time to study. Try to make the practice interesting, so is it not so resistant? When you learn something new in JavaScript, try to use it as a new toy, new car, new shoe, or anything else you're interested in trying. Then do not use the practice as a work, but exercise as a play. Try something cool with your new skills. Let yourself be amazed by the wonder. and show it to your friends. With a game of mind,

And for this kind of app crack, just find this switch, directly tamper can. And for some server-controlled functions such as video member information cracking is a bit troublesome, because your information in the server, the ser

even hovering could be a dimension of the phone's input. Although the report does not say whether the machine feedback has such a rich amount of value, but at least the hardware is ready, we can expect. If this technology can make a piece of a fixed dead tablet on a laptop feel like a tap, then the phone will naturally.Think about it, the memo on the phone really sticks, and the stamp you get on Facebook can really poke at you, and the world is really crazy.(This article to the automatic Point

, where the electronics engineers were heartily impressed by Apple's black technology. As for how to do it, I understand that: Apple found an FPC manufacturer, a breath of production of 2000 lines, and then one by one on the board to try, and finally pick out the use of the total of the two root. The plan was to do 2000 more if you couldn't pick it up.The so-called real high-tech comes from simple rudeness. Some people would think that this is

About ID tech 5 ID tech 5... it's really strange. Mega texture is actually a technology for dynamically detaching and loading rendering resources. The main topic of the next generation of ID technology is probably because the rendering technology hardware used in movie is unable to keep up with the uniform ID Lighting/shadow/shader solution, similar to the categories involved in global illumination (global
