原理 前文 脱离了广大机械硬盘和 USB 2.0 群众的实际情况，是不得人心的。下面介绍一种更加符合科学发展观的定制方法。 启动时，GRUB 或 extlinux 引导 /live/vmlinuz 和 /live/initrd.img， initrd.img 初始化之后会寻找 /live 目录下以 squashfs ext2 ext3 ext4 xfs jffs2 后缀的文件和以 .dir 为后缀的目录，然后将它们 union mount 成根目录。union filesystem，联合文件系统是将多个文件夹联合挂载在一个文件夹下，对联合目录的读写作用在指定为 rw 的分支目录上。 #initrd.img/bin/boot/9990-overlay.sh: 69 if [ -n "${addimage_directory}" ] && [ -d "${addimage_directory}" ] 70 then 71 for FILESYSTEM in squashfs ext2 ext3 ext4 xfs jffs2 dir 72 do 73 for IMAGE in "${addimage_directory}"/*."${FILESYSTEM}" 74 do 75 if [ -e "${IMAGE}" ] 76 then 77 image_string="${image

I'm building quadcopter based on Raspberry Pi. I want to stream video from webcam via cellular conection to my computer. I tryed ffmpeg and mjpg but it has to big delay to make it possible to control Quad only with watching video. My question is if it's possible to stream video with realy small delay (so small that I will be able to drive quad without problems)? If Raspberry's hardware isn't good enough, BeagleBord may do it? Also, mounting smartphone to quad will be last possible solution but I prefer soulution with Pi. UPDATE: I have used gstreamer for the streaming and Raspberry Pi camera.

Using the Windows 8 Live SDK you can have a user give you permission to their Microsoft Account. With this you can get their name and photo and more. But using the Live SDK appears to require the user of the app to use the same Microsoft Account as whoever is signed into the current session of Windows 8. In some scenarios, using a different account is very legitimate. I have simple sign-in working like a charm! This uses the same account. I can't find a way to do use another. Is it possible? You can call Logout after Init and before LoginUser. Here's the code for javascript: function LiveLogin

from jQuery website: As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. with version 1.7.1 i tried to change all my live() to on(), but none worked. Does anyone has any idea why? this is how it gets called: <script type="text/javascript" src="js/jquery-1.7.1.min.js"></script> and this is one of the scripts that don't work: $(".toBeSaved [col=ISRC] input").on('change',function() { var pid = $(this).parent().parent().attr('primary_key'); $("[primary_key="+pid+"] [col=isrc_id] input").val(''); $("[primary_key="+pid+"] [col=isrc_id] input").css({'border':'1px

Is there is a way to only let the inner element of a listitem do something? I have list elements that can contain a tags with a certain class. The inner a tags are bound to a live click event handler. The list items themselves have also a click event handler. Something like this <li>some text<a class="someClassName">some text</a></li> with the handler for the a tags $('#somelist li a').live("click", function(e) and this is how the event for li item is added $(markers).each(function(i,marker){ $("<li />") .html("Locatie "+'<a class="ol id"><strong>'+ids[i]+'</strong></a>') .click(function(e){

I’m currently using StickyFloat http://plugins.jquery.com/project/stickyfloat and am dynamically changing the height of the div the object sits in via jQuery, the changing of the CSS height works perfectly, but StickyFloat doesn’t recognise the new height of the div, it keeps the original height only. Is there any way I can kill stickly float and re-enable it again? It’s enabled with $('#floatCol').stickyfloat(); basically. My question is identical to How to make the jQuery Sticky Float plug-in react live to page changes? and it’s doing my head in big time. I wrote this plugin, and in a
