微软当年的成功,还有见天apple的成功充分证明。 软件企业牛不牛逼,和软件一点关
系没有。 99%拼user interface。 google是个例外。
当年微软之所以爆发了,就是因为windows把命令行变成了可视化。 但是,仍然有很大
门槛挡在人们面前。 我们小时候都叫“学电脑”, 学什吗? 学键盘,学鼠标,学
word, 学excel。

Last year, Apple announced that it was phasing out developer access to UDIDs
, the unique iOS device identifiers that allowed developers and advertisers
to not only track usage of their own content, but also in some cases track
users' movements across apps and browsing sessions. The company earlier
this year began rejecting apps that continued to use the UDID rather than
implementing unique identifiers that would enhance privacy by remaining
unique to the developer... 阅读全帖

Among the many software updates Apple has been pushing out associated with
yesterday's keynote announcements, Thunderbolt Software Update 1.2 is a
relatively minor 537 KB download offered to provide support for the company'
s new Thunderbolt to Gigabit Ethernet Adapter. The adapter is intended for
use with Thunderbolt-equipped MacBook Air models and the new Retina MacBook
Pro, which do not come with an Ethernet port built in due to their thin

不懂你的"User"是什么意思,是DB的user还是存在db里的user数目。
Access只有一个用户"admin"。但它用在程序里服务几百上千个user
数目都没问题。比如说,你有个web,用asp和Access连,有1000个用
户访问web,但实际上存取access的只有一个,即admin。其它都是
access里的数据。
很少有dbms支持100个cocurrent用户访问的。

这两天我们请咨询公司的scrum master做顾问,为我们做scrum,开了几天的会,我怎
么觉得他们很忽悠。scrum master帮我们做user story的分析,就写了些As..., I
would like to..., so...的纸条,然后要我们打分,我也不知道为什么纸牌是1,3,5
,8,13,30,然后直接200,300了。而且我觉得他们的user story分析的也不对,有
些是feature,有些很epic,根本break down不出什么task了。
我们知道agile/scrum的基本原则,user story应该以用户的角度为主,粒度尽量小一
点。但是大家做scrum的时候,user story和task都是怎么分析的?sprint是怎么计划
的?

- You are a member of the Administrators group on the system.
- You already have a domain account with a local profile.
- You want to create a local account that shares that profile.

To associate more than one user account with a single local profile, follow

For windows server, you can log in a few users at the same time(such as: you
login from the computer, and some other user can log in and use the same
computer at the same time).
For non server windows, you can still call them "multi-user" os, but you can
only log in one user at a time.

我现在在R里面做Optimization,但是中间需要提取user输入的数值,比如说budget,
然后在不超过这个budget的范围内来做optimization,怎样build一个interface让user
可以输入这个数值,然后R自动提取数值然后run给出结果?
User可以在Excel里面输入,可是不直观,我想知道能不能build一个app之类的东西,
后台是R程序,前台是user interactive的界面,让所有的code能dynamically地运行。
我查了一下Tableau,好像可以跟R integrate,可是能实现的功能非常有限。另外就是
用R里面的Shiny Package,目前还处在初步学习阶段。想请教大家,用Shiny这个方向

标 题: user virtual address space VS kernel virtual address space
发信站: BBS 未名空间站 (Sun Apr 18 17:14:09 2010, 美东)
32-bit machine,virtual address space 4GB,kernel(e.g. linux)会把这4GB,分成
3GB user/1GB kernel。
1GB kernel virtual address space跟物理内存是1-to-1的map。对user virtual addr
做virtual --> physical 转换是也是转到一个kernel virtual addr再到physical
memory。
那这样不是只能用到1GB physical memory,如果有更多
的就用不到了。windows也有这个机制,好奇这样的话不是加内存都没用?大牛给解释
一下啊

少于896M的话,我觉得所有的 physical address都能被kernel直接访问,都有logical
address.
user virtual addr 和 kernel virtual addr 应该可map到同一physical page吧,如
果kernel 想访问的话。
当user app 执行write或者read时,会通过相应system call 进入kernel mode,这个
时候kernel 应该直接用user app的page table 就可以了吧。我也不确定,我自己理解
的。。。

来自主题: JobHunting版 - how facebook stores user data
我想知道facebook是怎么存储user info的,我能想到的是 distributed server存,那
如果一个user在自己的wall上加了comment,这个comment应该和自己的user info一起
存在同一个机器,还是有专门的comment server。 如果在别人的wall上comment哪?
多谢了。

Are "authorized user" accounts considered by the FICO® score?
Published 01/08/2006 02:20 PM | Updated 10/15/2010 10:26 AM
Q: I'm an authorized user on someone else's credit card account that appears
on my credit report? Will it be included in my FICO score?
A: Yes. An account indicating that you are an "authorized user" is included
in your FICO score and is treated no differently than your other accounts in
which you are the account holder.

我以前没有credit card,是我老工卡的authorized user.现在想申自己的卡.听从chase
banker 的建议,前两个月从一张卡的authorized user转成cardmember.可是最近从
karma 看到我有四张chase credit cards.给chase写信,chase告诉我说,两张
authorized user, 两张cardmember.我是不是以后再申卡同样的卡,就不会有bonus了
。即使我撤消一张卡的cardmember.
另,chase sapphire可以申sapphire prefer吗?
