manual

I'm reviewing a manual of best practices and recommendation coding java I think is doubtful. Recomendation: String variable; "xx".equals(variable) // OK variable.equals("xx") //Not recomended Because prevents appearance of NullPointerException that are not controlled Is this true? Mark Byers This is a very common technique that causes the test to return false if the variable is null instead of throwing a NullPointerException . But I guess I'll be different and say that I wouldn't regard this as a recommendation that you always should follow. I definitely think it is something that all Java

一、手工编译ceph源代码。 1、下载ceph源代码。 从阿里云开源镜像网站下载当前最新版本的ceph源代码，具体下载地址如下： http://mirrors.aliyun.com/ceph/tarballs/ceph_10.2.1.orig.tar.gz 2、编译ceph源代码。 1）编译运行环境说明。 使用的编译和运行环境是ubuntu16.04-server-amd64，安装完ubuntu镜像后更新运行环境到最新。 #apt-get update #apt-get upgrade 2）解压缩源代码。 #mkdir -p /root/src #tar -xf ceph_10.2.1.orig.tar.gz -C/root/src 3）安装编译依赖包。 A）执行ceph源代码目录下的install_deps.sh脚本来安装必要的依赖（该脚本并不能完全安装编译ceph源代码所有的依赖） #cd ceph-10.2.1 #./install-deps.sh B）安装额外的依赖包。 #apt-get install libtool automake pkg-config cython libsnappy-dev libleveldb-dev libblkid-dev libudev-dev libkeyutils-dev libcryto++-dev libfuse-dev

How to disable autoload in jqGrid and load data manually when I need it? Thanks. Oleg If you set datatype to 'local' the data from the server will be not loaded. To force the loading of data you can change datatype to 'json' or 'xml' with respect of setGridParam method (see http://www.trirand.com/jqgridwiki/doku.php?id=wiki:options and http://www.trirand.com/jqgridwiki/doku.php?id=wiki:methods#grid_related_methods ) and then call trigger("reloadGrid") method. See jqGrid is not loading data which has also the information what you asked. Igor Just don't set the default URL in the table. And

I need to do a rather unusual thing: manually execute an elf executable. I.e. load all sections into right places, query main() and call it (and cleanup then). Executable will be statically linked, so there will be no need to link libraries. I also control base address, so no worries about possible conflicts. So, is there are any libraries for that? I found OSKit and its liboskit_exec, but project seems to be dead since 2002. I'm OK with taking parts of projects (respecting licenses, of course) and tailoring them to my need, but as I'm quite a noob in the linux world, I dont even know where to

There used to be, but there don't seem to be any direct links. A little digging around revealed some answers which I thought it would be useful to share. These are links to the manual in one page - useful for offline use or creating a PDF using Dardo Sordi Bogado's build script. 1.2 Manual in one page https://web.archive.org/web/20120730003805/http://book.cakephp.org/complete/3/The-Manual 1.3 Manual in one page https://web.archive.org/web/20120730004040/http://book.cakephp.org/complete/876/The-Manual GOOGLE DOCS - CakePHP 1.3 Manual You can download CakePHP's manual from their website: http:/

In polymer I'm trying to manually submit a form. My form looks like this: <form id="myForm" on-submit="{{ submitForm }}"> <input class="text" value="{{ someValue}}"> <button type="submit">Submit</button> </form> And in the polymer object I have: submitForm: function(e) { e.preventDefault(); } Whenever I try to do the following: document.getElementById('myForm').submit(); the form totally ignores the on-submit attribute and posts the form to a new page. I'm building a on-screen keyboard for anyone wondering why I would want to do this. I need to submit the form whenever someone hits the enter

I used 'package.skeleton()' to generate .Rd help files a few months ago. I have edited these files, and I have also changed the functions, removed some functions, added others. Is there a function that automates updating the Rd files? update A nice package was just released called Rd2roxygen , it is described by the author Yihui Xie on his blog . As the name implies, this package allows one to retroactively insert documentation currently contained in .Rd into .R files. Sounds like a promising approach for both learning roxygen and for converting packages currently in development to R packages.

How can I manually rotate a view using the autoresizingMasks, as if the user had rotated the phone and it had auto-rotated. Also I want it to be instant, no animation. I you want to know why I need this, look at my other question at iPhone Dev - keeping interface rotation . Thanks!! What you want to do here is use Affine transforms to rotate your View, I have accomplished this though i dont have the code infront of me at the moment. If you do a simple rotation youll find that your view will be cut off and not in the center like youd want, what you need to do here is set the anchor of your
