iting should be used everywhere though.
and of course the idea is not new. in fact, every lock is internally impleme

tely hardware guarantees an operation is atomic. |

标 题: OpenSuse在KDE下点击了lock screen之后，机器废了
发信站: BBS 未名空间站 (Mon Mar 13 10:17:49 2017, 美东)
有没有用OpenSuse的大虾？我在KDE桌面下，点开始
菜单（蜥蜴头），选择电源按钮，里面有log out,
lock screen,power off 等等，一旦选择了lock screen，
这机器就完旦了，症状就是等logout之后，再想login进
入图形desktop, 机器慢得无法使用，几十分钟才能完
成login过程，然后点一下鼠标需要十几分钟才见反映，
非得重装操作系统。这问题我从10.1到13.2都中过招儿，重
装过不下5次。有没有人遇到过类似问题，可知道解决办法？
多谢！ |

但是对于web来说一般没啥问题。
：lock应该是通过CPU的特殊寄存器实现一段代码的atomicity,多个server不知道是不是
：lock,你不怕慢，就用 MYSQL 搞个transactional counter,同步的核心就是TCP那套，
：握手，校验，sliding window. |

须lock in rate以后才给，只是给了我口头上的estimate，interest rate和closing
cost都要比A低。
但是
1. A已经fully underwritten，我还有3个礼拜就要close，所以A时间上没有问题。但B
还需要我提交资料在审核，所以时间上我不太确定
2. A家可以matchB家offer，但是需要B的正式的estimate。但到现在B还没给我
我现在倾向A家，想等B家给了我正式的offer就让A match。但是B家已经lock in rate
，不知道这样以后换有没有问题。我现在在B家什么也没有签，只是提交了资料，签了

换出(anti-lock system), 只好使用手动release, 就是打开P挡边小孔盖子,用镙丝刀
揿下时,换出P挡. 到修车铺一问,老板说可能是有根cable坏了,修一下要300刀. 本人
寻思太贵,加上车子挺老,遂作罢. 过了段时间,发现表盘指示灯也不亮了. 最可气的是,
尾灯,刹车灯,high mount light通通不亮了. 去修车铺问,答曰, 电路有问题,检查要2
小时,35刀, 修至少3小时,费用再说. 由于当天没时间,就回来了.
后来, 到了周末,决定DIY一下再说. 先打开手册, 找到有关保险丝部分. 读了以下, 发
现有一个保险丝控制尾灯,刹车灯,仪表盘灯和anti-lock system, 大喜. 于是,按图索
骥, 找到了保险丝,发现有两个保险丝烧坏了. 接着打开尾灯座,发现有一个刹车灯炮
底部的两个金属接触点熔合了(一个管尾灯,一个管刹车). 还有两个灯座看上去有问题(
左右各一个).是买来了保险丝和刹车灯, 我就开始试.. 先换下坏灯, |

发帖数: 2386 | 41 Hi,
I have a 2001 Honda accord, the trunk lock can be opened without any
problem before, yesterday while I am opening it using the latch inside below
the driver's seat, my son was goofing around sitting on top of the trunk,
then I found out when I put the key in the trunk lock, it cannot turn ( the
master key can insert deeper, the valet key seems have trouble to insert
deep). I can still open it from the latch under the driver's seat. Is
there any way to fix this?
Thanks |

Wheel lock的作用就是给小偷造一点麻烦，也许小偷就跳过这辆车了。要是小偷铁了心
要偷，那也是没有办法了。我知道MDX的wheel lock，一共有十种pattern，小偷把十种

发帖数: 12525 | 47 大部分wheel lock都是高强度不锈钢的,强度非常大,普通钻头根本钻不下来,
要用碳化钨的,一个碳化钨钻头好几十块钱,投资太大,这还没算买电钻的钱,
所以除非你象他一样是开shop的,不然完全不实用.
最佳办法是在menard买个dremel的9910号碳化钨cutter,10块钱:
http://www.dremel.com/en-us/Accessories/Pages/ProductDetail.asp
然后去买个menard自己牌子的最便宜的rotary tool,10多块钱,然后用这个玩意沿
wheel lock 四周切割,把圆形外形切成六角形的,不需要精确,大致象就行了,然后敲
一个socket进去,就能拧出来了.
对了,最后提一下,这碳化钨切刀真是削铁如泥,除了金刚钻,就这玩意最好用了,
不出几分钟就切好了. |

发帖数: 1342 | 48 Had a flat tire yesterday. Tried to take off the flat tire, found out one
bolt is different from the other 4: that one is locked. Called AAA. They
asked me check the glove compartment to see if there is a key to the lock. I
found it. I removed the flat tire.
Initially I put on the spare on the wrong way (Inside out). When I tried to
drive, I coud hear the noise. Had to do it all over again. Eventually I got
it right.
Today I took the car to garage and they fixed the flat tire. |
