在任天堂财报大会的问答环节中,任天堂社长君岛达己针对财报中提到的下一个财年软
硬件销量预期回答了投资者的提问。他确认任天堂希望并计划让Switch卖得和Wii一样
好,并通过在接下来的一个财年中卖出1000万套Switch向第三方发行商等合作伙伴证明
Switch的发展前景良好。
以下是君岛达己社长问答中部分重点摘录:
-任天堂Switch硬件的订价不会对收入产生负面影响,但是想仅通过销售硬件就盈利的
话还需要时间,因为当产量达到一定等级的时候才能降低生产成本。多样的Switch外设
销售也能起到帮助。
-向玩家展现Switch创新的游戏风格很困难,所以他们采取了新的企划,诸如前往众多
地点举办体验会以及积极地进行宣传。
-以上两条策略不一定能在接下来的财年中立刻见效,但是君岛社长相信随着Switch的
发展最终将会看到收入的提升,这其中年底的消费季很重要。
-接下来的财年中计划卖出1000万台Switch,这一数字考虑到了在3月份销售超出预期这
一事实以及未来的软件发售计划。另外,有1000万台装机量是创造商机的基础,这可以
让包括发行商在内的合作伙伴意识到Switch的未来前景良好... 阅读全帖

DETROIT/WASHINGTON (Reuters) - General Motors Co in 2005 decided not to
change an ignition switch eventually linked to the deaths of at least 13
people because it would have added about a dollar to the cost of each car,
according to an internal GM document provided to U.S. congressional
investigators.
The U.S. House Committee on Energy and Commerce released the documents on

这个正解。
有些Switch有扩展port,可以在几个switch之间享用同样的带宽。不过没见过。
Wi-Fi只能从router走了。在实际应用中有影响吗?

switch是在同一个子网内连接多台机器。Router是连接两个子网.router的WAN端口在一
个子网中(实际是外面的网络),另一半(LAN)实际就是switch。
如果你在公司,可以连多台机器进网络,用switch就可以了,比router快。
如果你在家连接多台电脑上网,网络公司只让你连一台电脑,你就需要用router.
如果你家需要上网的(有线)设备超过了router的LAN端口数(通常是4个),你就需要
用一个switch增加局域网的连接容量。一个5端口的switch可以多连3个设备(从4个设
备增加到7个设备),一个8端口的switch可以多连5个设备。我家里就是一个router+一
个8port switch.

怕被你骂啊。
1.hub和switch一直都是分的很清楚的。不清楚的是switch和router,现在的switch很
多都是layer3,叫MLS,有router的功能,和router的区别是一个by default,一个需
要command,比如ip routing去enable它,你学了ccnp,就知道有route port这个概念
,不能吃一口大胖子啊。
2.switch也不会记忆mac,switch是记忆port口,你看TCP、IP的书,会画switch是1,2,

我把旧家里的switch都换成那种长方形板的那种,觉得比原来的小switch好看。
除了3个,全都换了。这三个(一个是ceiling fan with lamps, 一个是control
garbage disposal, 还有一个是厨房开关)的电线是#12 or #10 不是其他开关的那种
比较细的#14。
ceiling fan with lamps 的switch换完后,发现电扇转得比较慢,灯也变成只有两个
亮而不是三个都亮。
请教,是我螺丝拧得不够紧还是需要换别的switch?
多谢大家。

非常感谢。 已经解决了,确实是 pressure switch的问题。也是朋友指点,把inducer
和pressure switch之间的管子从inducer那里拔下来,吸了一下,听到pressure
switch那里轻微的嘎巴一声,然后重新安回管子,就工作正常了。
刚开始也是怀疑管子堵塞,把管子都拔下来,吹吸,没有堵塞。后来朋友电话说得连着
pressure switch吸,才解决了问题。
再次感谢,希望对后面有类似问题的人有帮助。

If pressure switch is open, it means the venting system does not work
properly. Without venting, combustion byproducts will stay inside house.
Inducer failure or vent pipe clog and other things could cause pressure
switch open. furnace will shut down if pressure switch is open,it is a kind
of safety feature.
Pressure switch can fail too. But should assume pressure switch does it's

1. Switch operats on the layer 2, data link layer (of course, the regular

2. Router operates on the IP layer, layer 3
So, to answer you question:
Switches don't know the routing. If they are connected to the same subnet,
nothing needs to be done. If they are connected to the different subnet, you
need to put a router between them. Switch isn't counted as a hop, router is.

看了看,context switch分两步:
1. Switching the Page Global Directory to install a new address space; .
2. Switching the Kernel Mode stack and the hardware context, which
provides all the information needed by the kernel to execute the new process
, including the CPU registers.
应该是整个PCB都被switch 进入kernel stack,

thanks~基本知道怎么fix了
找到pressure switch,把那根管子拆了下来拿我的小打气筒一打,switch就咯噔一响
开了
然后开气开电,起来啦~~
可惜起来以后switch又关不上了,所以点不着火。。。明天去买个新的switch装上估计
就行了

Goodman gas Furnace 2004年安装
现买的房子的第一个冬天。前几天可以正常使用。
现不能启动,主板B14933241显示2 flashes,
故障是"Pressure switch stuck closed"
将Pressure switch 和induce motor中间的塑料管断开
或者将Pressure switch上的两根电线断开一下,都能正常启动达到设定的温度,
但温度降低后,又无法启动,只有induce motor在转动。
mechanical venting system出风口检查,没有堵塞。
正常启动后,出风口热风很大。
condensate draining也清理了,现在是干的。
换了新的Pressure switch还是同样的问题。
请问需要换新的induce motor吗?
还有哪些部件可能有问题?
谢谢。

谢谢dealseaker和imore提供的信息。
对不起,前面提供的信息表达可能不是很清楚。
1),尝试了新的pressure switch,故障依旧。
新的和旧的pressure switch用嘴吸都能听到滴答的声音.
2),主板上的黑盒子敲了敲,同样的问题还在。
3),inducer马达只有在室内温度低于设置温度时候才启动,但是无法启动furnace.
只有将Pressure switch 和induce motor中间的塑料管断开,或者将Pressure switch
上的两根电线断开一下,才能启动furnace.
现在的问题,是不是只有尝试换主板?
谢谢

来自主题: shopping版 - router, hub and switch之简易指南
总结一下吧,省的大家越来越糊涂
事先申明,本人不是专家,只是说出自己作为consumer层面的理解
如果你在使用cable/dsl服务, 而且你的isp只支持一个IP(也就是一台机器直连)
那么我建议你使用router, 大多数的router兼有小型hub/switch的功能,它本身相
当于 一台小电脑, 由router去获得外部IP, 再分配给与它星形连接的所有电脑,每个电

获得的IP地址是以192.168开头的内部地址,当然router还有很多其他功能例如firewall,
NAT.....等等就不详细说了
至于hub/switch, 对于个人用户功能基本是一样的,
只是若干台机器共享一个网络口的solution
(所以说一般router也有hub/switch功能), 每台与hub/switch连接的机器独立获得
一个外部IP地址, 独立和Internet连接

我不是说产品啊,瞄了一眼,Cisco ER,switch revenue居然比去年少了7%!!!JNPR
是去年
环比增加了66%,整个switch 产品shipment和去年比,应该是增加的。Cisco的Switch
咋回事
啊?不是出来什么Nexus nK,是不是技术上落后了?

我觉得,好像现在很多的Switch上面的新技术,(最少对我而言,,好久没有碰switch
了),象DCB, ethernet fabric, virtualization,100G,好像Cisco跟进的比较慢啊。
又看了一眼,上个Qtr,Cisco Switch Rev是3.7B,这个Qtr只有3.15B,一般Q4是
Strong Qtr,要是这么算的话,Cisco在Switch上一下子就丢掉了550M!!!
这个肯定不是什么一个两个contract的问题,一定是技术上,或者Strategy,或者2者
上出了大问题。

来自主题: TVGame版 - switch上市后的一些更新
原来老任承诺的要release在switch上的的游戏,一部分跳票,或者转战ps4了。比如怪
物猎人:世界。
首发这几个月,switch居然还是那么几个游戏。跟当年gba, nds上市情况基本一样,出
个官方的模拟器,然后在Switch上卖老游戏。
现在任饭比较期待的游戏居然是,贝姐2的switch版。 youtube上还很多人觉得任天堂干
得很好。
