发帖数: 922 | 4 dockstar上装 debian并不wipe原来的firmware。只是改了boot order，所有的东西都
装在USB drive上。所以安全很多。你只要把USB drive拔了，就会boot original
firmware。
硬件上CPU强，USB drive space也大多了。而且root是native在USB drive上可以RW的
。你要用pogoplug RAM是256MB，比神油也大一倍。
软件上用的是full-fledged的linux。repository本来就大，你还可以把developement
tools装上去，自己从source-code 编译。 |

对!你用了upgrade,就可能出现这些问题。Ubuntu 12.04LTE和11有很大的区别。Gtk神
马的库也都变了。如果你upgrade，原先的库可能就不能用了。另外，原来的库的
aptget连接更新（repository)都不存在了，也就不能更新了。
答案，就是你得重新装这些库。 |

逼了
一旦ubuntu声称不支持某版本，那个版本上的package很多就都不能自动用aptget来
update了。解决方法一般有两个：一个就是更改/etc/apt/sources.list，让它指向新
的repositories；另一个就是自己下载source code，重新configure, make, make
install。但是用pkconfig装的，就麻烦一些了。新的mesa、gtk+库把很多函数原型都
改了，就是为了和OpenCL之类的竞争，弄了很多麻烦出来。如果你做开发，你的相应的
code都得要改，否则不能make通过的。 |

发帖数: 2771 | 9 一句话 exec's summary: there is no need to mess with it.
试了试几个攻略，一个是装ipkg，相当于redhat下的yum repository。一个是装
archlinux，package新。一个是装debian，用的人多。但是具体到扩展应用，不外乎加
装samba, squeezebox client/server, airplay server, bt, etc。
其实pogo本身带的pogo backup就可以把pogo带着的所有盘映射到本地盘符，还能远程
，比samba方便多了。 pogo本身也带DLNA，不用另装。我觉得pogo软件太赞了。虽然不
能sync directory, 无法取代dropbox，但是比windows上绝大多数backup软件好用多了

unless you do a lot of iOS app dev, I don't really see advantages of xcode
over gcc/llvm in Linux.
xcode compiler/libraries often conflict with those from macports. gcc
version management in xcode is also pretty messy. sometimes "xcode-select"
won't point to the correct version, and one has to manually create links.
if you want to use software repositories to manage packages, like in most
Linux distros, macports is incredibly slow and finicky when installing/
building packages. compare to macpo... 阅读全帖 |

you must have installed grub on the Linux partition (say, /dev/sda5) instead
of the partition with mbr (/dev/sda). you can fix it by reinstalling grub
to /dev/sda.
you can do this by (use sudo fdisk -l to find out which one is your boot

sudo grub-install /dev/XXX

always install cuda via nvidia's upstream repository. make it much easier to
reinstall/upgrade.
also run
nvidia-smi
to make sure your nvidia driver/cards are properly installed
to test for opencl library, run
sudo apt-get install clinfo
and type clinfo to see if your gpu is detected.
if any of these fails, type "echo $LD_LIBRARY_PATH" to see if you have
included the needed path to libopencl.so. |

发帖数: 6599 | 21 I have been using git to manage my core files (almost everything, except

My repository (bare) has grown from from 3GB to 8GB (you will be surprised
how slow your real creations grow once you start organizing your files).
Once you checkout a copy, the total git folder is about 2x of the bare repo
size - to me, is about 16 GB plus un-tracked files (mostly those do not

As must as I like ruby for a script language, I've
never been a big fan of RoR - or any web framework
entirely based on a DSL.
I've been toying with the idea of incorporating
ruby into the JEE framework. Ruby is ideal for
implementing the more "volatile" parts of the architecture,
for instance the request handlers, the business validation
rules, etc.
OTOH, I'd like to stay with good old java for the
domain model, and the service and data repository tiers. |

有一点about windows Xp env,
if you are using it.
by default maven saves all jars under your home dir .m2
but on xp it could be a long dir name with space in it,
e.g.C:\Documents and Settings\youruname\.m2
some compiler/maven plugin may fail because of that.
the solution is to put a settings.xml under the dir to re-direct
it somewhere else:
