新编译的系统启动时停止在freeing unused kernel memory：XXXK没有其它的任何信息，不知是何原因？在/etc/inittab文件中有si:sysinit:/etc/rc.d/rc.sysinit这一行，而且单独运行/etc/rc.d/rc.sysinit也可以运行。

Now that you understand variables and operators, it's time to learn about expressions, statements, and blocks. Operators may be used in building expressions, which compute values; expressions are the core components of statements; statements may be grouped into blocks. Expressions An expression is a construct made up of variables, operators, and method invocations, which are constructed accordi...

系统启动出现这个问题，应该怎么处理啊！！！ swap:invalid number of blocks 这个总是应该怎么处理啊！！！拜托各位大侠帮忙！！！ [ 本帖最后由 qq28289877 于 2006-1-20 14:03 编辑 ]

select * from dba_tablespaces where tablespace_name='FST' 显示block_size=4096,initial_extent=65536,在企业控制台里的tablespace map发现每个区占用16个块(可以这样理解吗?)，所以大小应=（4096*65536*16）/（1024*1024*8）=512m,可是我为该表空间建的数据文件只有5m大小，到底哪有问题？

Major IP Addresses blocks By Country In this section, you can find the list of all major IP address blocks allocated for each country. For countries in europe and in the middle east, the name of the company/Internet provider that own these IP blocks is also displayed. In order to show only the major IP blocks, only IP blocks with 4096 addresses or more were added to the list. For United States, on...

class Project has_many :tasks def self.all_names find(:all).collect(&:name) end end 看懂上面的方法没有？ 为什么可以这么用呢： find(:all).collect(&:name)? &的作用是什么呢? 我们习惯的用法是： find(:all).collect{|p| p.name}, 后面的collect方法将每一个对象执行.name方法，然后返回到一个数组中。 而&:name 的作用就是将name 方法转化成proc， 相当于 :name.to_proc 对，&:name 就是一个shortcut...

blocks are supposedly the most liked feature in Ruby . This proposal would enable a similar feature in Python: using webapp.runner do (config): config.time_zone = 'UTC' config.log_level = 'debug' Compare that to the Ruby equivalent: Rails::Initializer.run do |config| config.time_zone = 'UTC' config.log_level = :debug end Unless I am missing something fundamental, adding a do st...

请高手告知有关方面的材料 提供些建议

系统引导至freeing Unused Kernel Memory就不走了 。谁能给点意见。 谢谢 :shock:
