唔識睇英文咩 段news release咪講左

The problem with this isolation is that some programmers are reporting performance hits after systems are patched. The Register reports that the slowdowns could be between 5 and 30 percent depending on the exact Intel processor. While Linux patches have been rolling out over the past month, a Windows 10 patch is not yet available. Some are speculating that Microsoft will deliver this in an upcoming Patch Tuesday, as the company started separating the NT kernel memory with Windows 10 beta builds in November. “We have nothing to share at this time,” says a Microsoft spokesperson, in response to a query from The Verge.

真patch 未出
但呢度已經有人響度試

理得佢
係咪煙條都已經誠信破產
下一次upgrade 就跳槽

睇zen2同9代效能比較
如果9代仲有呢d on9 bug就唔會考慮

今年叫Zen+,下年先Zen2

所以咪話ZEN 2同9代

呢啲hardware bug有排整啊
緊係出咗先啦
2018-01-05 14:19:47
其實個BUG據我了解, 以真實例子來講

1.你去旅行, 去到機場
2.坐上飛機, 去埋目的地
3.入住埋酒店, 仲玩左幾日
4.突然收到你居住地的機場打俾你手提
5.同你講「你上機前我地忘記左睇你PASSPORT是否有效, 不如你影張PASSPORT相俾我睇, 就當CHECK左你好嗎?」

問題係若果你係恐怖份子, 你可能第6步就係準備引爆炸彈

好尷尬。。。。
