MY VOYAGE

Repost from https://stackoverflow.com/questions/15176104/c11-range-based-loop-get-item-by-value-or-reference-to-const If you don't want to change the items as well as want to  avoid  making copies, then  auto const &  is the correct choice: for ( auto const & x : vec ) Here is recap: Choose  auto x  when you want to work with copies. Choose  auto &x  when you want to work with original items and may modify them. Choose  auto const &x  when you want to work with original items and will not modify them.

Two necessary steps: Step1: sudo apt-get install libpcl- 1.7 -all libpcl- 1.7 -all-dev libopenni-dev libopenni-sensor-primesense-dev OpenNI should be installed while PCL is installed. PCL can be installed from its offical website. Just don't forget to install ibopenni-sensor-primesense-dev. Check the follwing link if you would like to know more details:  http://robotica.unileon.es/mediawiki/index.php/PCL/OpenNI_tutorial_1:_Installing_and_testing) Step2:  Copied from the following link: http://robotica.unileon.es/mediawiki/index.php/PCL/OpenNI_troubleshooting#ASUS_Xtion_PRO ASUS Xtion PRO In order to get our Xtion device working with OpenNI, we have to modify a configuration file: sudo nano / etc / openni / GlobalDefaults.ini If you installed OpenNI manually instead of using the repositories, the file is located in a different path: sudo nano / usr / etc / primesense / GlobalDefaults.ini Find ( Ctrl+W ) the line that says  ";UsbInterf...

I also tested the following installing procedure for OpenCV 3.0(2015-06-04). It worked well. The following procedure is copied from: http://rodrigoberriel.com/2014/10/installing-opencv-3-0-0-on-ubuntu-14-04/ In this article, we’ll see how to install the computer vision library  OpenCV 3.0.0 alpha , latest release, released two months ago (Ago 21, 2014) , on  Ubuntu 14.04 LTS (Trusty Tahr) 64 bits . For those who already have installed previous releases, you’ll see that, basically, nothing has changed and it’s as easy as always. Watch the  demonstration video  to see how it works. Notes: - Tested on Ubuntu 14.04 LTS 64 bits and 32 bits; - Tested on release 3.0.0  alpha  and  beta  of OpenCV; Pre-requirements: - Ubuntu 14.04 LTS 64 bits or 32 bits installed and updated; Lets get it started! As I wrote in the pre-requirements, is always nice to have your OS updated. Then, run apt-get update and apt-get upgrade before we re...

(This is mainly a record for myself when I need to do all these agian in the future. No any suggestion for others.) I bought a new laptop with Windows 8 preinstalled recently. In UEFI mode, it is completely suffering when trying to install a new Ubuntu with Windows 8. Right now, you may spend a lot of time and effort, but still fail to do that finally. After 2-3 days, I decided to completely remove Windows 8 in UEFI mode (the disk partition is ugly anyway), and switched the fireware mode to LEGACY mode. Then in LEGACY mode, I installed Windows 7 and Ubuntu 12.04.5 LTS. Always remember there can be only 4 primary partitions in the disk in this way. There seems to be a "System Reserved" partition in Windows 7, which is also a primary partition. The partition used for Ubuntu 12.04.5 is an extended partition, which is also a primary partition. As a result, theoretically, there are only two primary partitions left, which you can use for Windows 7. Of course, there are ...

刚刚看完日本电影《嫌疑犯X的献身》，非常不错的一部电影，日本的侦探系列故事一直不错，但这部电影本身也不仅仅停留在侦探系列悬疑的本身了。很多东西被理性地分析以后就索然无味了，所以感性地写下几个小小的感想： （1）石神是数学天才，却遭遇着无人赏识的潦倒人生，回想过往总总，愈发让我觉得人生，小到买一件普通物品，无需在用力刻意追寻过多的完美。因为不完美，才是最完美最真实。 （2）纵观日本电影，从早期的黑泽明《罗生门》，到最近的《入殓师》等等，日本电影在思想性、艺术性上都很有高度，追求对人类本性的探究以及对爱的颂扬。但联系最近的钓鱼岛事情，更加觉得人类又是如此的矛盾，有时候很理性，却有往往被民族性的狂热和斗争冲昏头脑。很多时候，人与人之间能做到的事情，上升到民族、国家层面却很容易因为同类认同感充满了斗争。 （3）也许男主角汤川才是最搅局的，真相很多时候都并不代表正义，石神选择了去坐牢作为他杀害流浪汉的代价，给自己做了审判，也算符合了正义，为何硬要把花冈牵扯在内？她们付出的代价从“正义善良”的角度完全没有意义。对于她们，摆脱过去的阴影，幸福乐观地生活下去才是对这所有的牺牲最大的回报，而不是去坐牢。
