密码提示问题
December 31, 2008 3:33 pm GMT-0700 | In Life | 11 Comments | hide今天有个网银突然登录不了了,问我密码提示问题:第一个男/女朋友的名字?
我回答了 N 个都不对,感觉眼前刷刷刷的闪过十几年的时光。我想如果某人在我旁边肯定要抓狂了……
到最后我也不知道到底回答对了没有,反正它给我换了个问题。到底是我当初乱写了一个还是?
呼吁去掉这种可能导致家庭矛盾的八卦问题!

Live.com
December 19, 2008 11:29 am GMT-0700 | In Tech | 13 Comments | hide曾几何时,bbs 文章里加了附件就去不掉了,只能把文章删掉。实际上,系统管理员还是看得到删掉的文章的,所以一般推荐的毁尸灭迹的方法是(假设这个论坛系统是由心理健康的团队制作的),删除附件(如果可能)、删除文字、最后再删除文章,这样基本可以保证只有闲得蛋疼且拥有服务器直接操作权限的家伙才有可能恢复那个帖子。KBS 系统里面,后来是 etnlegend 写了增删附件的核心和 term 部分的界面(我只是顺手写了个 web 部分的接口),bbs 才慢慢滑入了 21 世纪的轨道,美女 show 完照片可以及时删掉以防 wsn 骚扰。
就在最土鳖的 bbs 也慢慢披上了 Web 2.0 的衣裳的时候,Live.com 却悄悄的把它们的时钟拨回了 20 世纪。在 Live space 里面删除了的博客文章,仍旧会显示在它自己的 what’s new 里面(包括内容提要,但是可以手动删掉)。好吧,我承认,在如此“庞大”的一个系统里面,要保证 consistency 确实不是一件太简单的事情;但是删掉的博客文章不再让别的用户看到,却理应是最基本的隐私规则,对于 Live 这个 bug 我能说什么呢?要么,是 PM prioritize tasks 策略有问题;要么,是 engineer 缺乏 common sense;要么,这难道是一个 feature??
Live.com 最近一次改版,不但 bug 层出不穷,还搞得很八卦。现在 MSN 昵称变化都有记录了。康神是一个好人,每次上 WC 都要改一下昵称以免误事。结果我等教众只要去康神的 profile 看,就可以知道康神如厕时间表……善哉善哉。Live.com 你向人家 SNS 取经,也要动动脑子,不要什么东西都拿来随便一抄,搞得人不像人鬼不像鬼。再比如说,页面上方大大的一个“People you might know”,我琢磨着 Live.com 的六度理论练得是不是纯熟,顺手点进去一看,蹦出一提示“We don’t have any suggestions for you now.”,你这不耍我么?没货早说啊!
还不止这点破事儿。Live space mover 的作者 broom 怒道:
Stupid Live Space!!!
我就不明白了,评论的时间只显示月日不显示时分秒是啥意思……
而月份的表示,七月份是四个字母“July”,十一月就变成了三个字母的缩写加一个点儿“Nov.”,发指的是九月份居然是四个字母加一个点——“Sept.”…… 这真是癞蛤蟆跳脚背——不咬人恶心人……
管Live Space的同学你们有那么闲吗??有吗???!
broom 说,这一次的升级已经把他击溃了。还有,Photo permalink 换了,导致 rss reader 里面像洪水一样刷出几十屏的老照片。Alpha 对此评论说:“Live space 隔个一年半载就来这么一遭”,看来大家对这个问题也见多不怪了。我以前还提到过另一个问题:
……微软的 Live Spaces 里面的 Blog Entry 发布时间默认是不显示年份的,有时候搜索到一篇文章却死活找不到哪年发表的,告诉我几月几号有个屁用啊……那帮写程序的家伙也许从来没想到过 Live Spaces 能活过一年,所以“前瞻”到年份信息是没有意义的……
博客说到底不就是一个内容发布和留言板系统吗,如果放学校里做顶多算个 network 101 的小作业,final project 都算不上。Live.com 却整得巨复杂,还特慢,稍微差点的机器开个 Live space 就跟死机了似的。随便抓个开源的框架都比 Live 的轻量、简洁、漂亮、全能。Live.com 的 infrastructure 听说也是相当牛逼的,怎么前端会搞成这么个样子呢?
论文答辩流水账
December 11, 2008 6:24 pm GMT-0700 | In Life | 20 Comments | hide10 月底碰到 Jimbond,得知我还没有定答辩时间,大惊。说人家都是提前三个月定时间,五个教授要同时出现三小时,哪有这么容易搞。于是赶紧和教授们讨论把时间定在了 12 月 9 号下午两点。
答辩前一个星期,有个教授突然说时间有冲突,晕,不是说要提前三个月选日子吗,提前一周换时间简直是不可能的任务。Email 群聊了一通,发现最好的情形是改到 12 月 9 号或者 10 号上午 ,这样五位教授里有四位能出席,剩下的问题就是临时改答辩委员会成员。临时改委员会的先例并不是没有,朱棣文有个学生答辩,委员会里有人睡过头了,未来能源部长的时间哪里是随便好浪费的,只见朱棣文冲到会议室外头就近抓了个物理系教授到会议室,然后答辩就顺利开始了。这样看来,我提前一周换委员会也没什么大不了的。于是我找了个很和蔼可亲的教授,好说歹说总算让我傍晚五点半去找他先讲讲概要再决定答不答应我。(感谢 tension 给我开那个楼的门!)然后说了半天,总算答应我了,于是很愉快的给另外四位教授发信,敲定 12 月 10 号的时间(和蔼可亲的教授只有 10 号有空)。
然后过了半小时,那个原本来不了的第五个教授给我发信,说他千辛万苦改了日程,所以 12 月 9 号上午他可以来了……Orz,我如果回信说,谢谢您,不过我不要您了,这样实在很不好吧。(此处省略若干字)最终结果是,我没有换委员会,然后时间定在了 12 月 9 号上午十点。
答辩前四天,得到消息说我们有篇写了四年、才三页的 paper 被接受了,于是很开心的在 ppt 里改了一个词 submitted -> accepted。这是我答辩中唯一在正式杂志上发表过的内容,顿时感觉底气足了很多。不过后来那张幻灯片被我自己砍了,白高兴了一场……
答辩那天提前半小时到会议室,发现投影仪的视频线被偷了。我找楼管一起在他的百宝箱里淘了很久,居然没淘到合适的线,倒。幸好 Ping 跑到旁边楼借了个投影仪。(Ping 是老板的秘书,是大大大好人。)
答辩前 icy 和 baoer 跟我强调,幻灯片数量一定要一减再减,于是我从 29 张减到了 24 张(这里面包括 title、outline、conclusion、acknowledgement,所以实际只有 20 张)。答辩前 15 分钟碰到老板,我说我怕一小时讲不完那,老板说,easy 45 minutes talk,再减幻灯片!于是我又临时减了一张。最后 50 分钟讲完,加上老板 intro 2 分钟,Q&A 5 分钟,成功在一小时之内搞定 public session。
Close session 反而相对轻松,和谐讨论问题显然比我一个人胡侃要便于交流。出来以后,教授在里面讨论了两分钟就发出爆笑(很想八卦他们笑什么,最后没敢问),然后门就开了,一一握手。接着开香槟,在天花板上砸了两个很浅的坑,准备过几天拿支笔去标注一下。
P.S. 偶的论文题目是:Gravity Gradient Survey with a Mobile Atom Interferometer。
Mac 打呼噜
December 11, 2008 3:21 pm GMT-0700 | In Tech | 6 Comments | hide昨天晚上睡不着觉转眼珠玩儿,发现 Mac 那个呼噜灯在视野里是间断的,不连成一条线,于是想到那个呼噜灯应该是脉冲发光的,通过不断调节占空比来调节(视)亮度模拟呼噜。其实早就应该想到的,对于 LED 发光来说,调节占空比显然比调节亮度本身要容易得多,而视觉暂留效果不用白不用。今天到实验室拿仪器测了一下果然如此,脉冲频率 153 Hz 左右。查了一下,苹果有一个相关的专利 US 6658577。

乔帮主八卦
November 21, 2008 2:53 pm GMT-0700 | In Misc | 2 Comments | hideMagicGlaive 前几天在 Facebook 上 share 了 Steve Jobs’ 2005 Stanford Commencement Address。这个 video 很古老了,不过再看还是蛮有意思的,摘要一下乔帮主的讲话:(好吧,我承认这篇 Blog 其实是为了 link MagicGlaive 而写的……)
… …
If I had never dropped out, I would have never dropped in on this calligraphy class, and personal computers might not have the wonderful typography that they do. Of course it was impossible to connect the dots looking forward when I was in college. But it was very, very clear looking backwards ten years later. Again, you can’t connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something — your gut, destiny, life, karma, whatever. Because believing that the dots will connect down the road will give you the confidence to follow your heart, even when it leads you off the well-worn path, and that would make all the difference.
… …
I had been rejected, but I was still in love. And so I decided to start over. I didn’t see it then, but it turned out that getting fired from Apple was the best thing that could have ever happened to me. The heaviness of being successful was replaced by the lightness of being a beginner again, less sure about everything. It freed me to enter one of the most creative periods of my life.
… …
I’m pretty sure none of this would have happened if I hadn’t been fired from Apple. It was awful tasting medicine, but I guess the patient needed it. Sometimes life is going to hit you in the head with a brick. Don’t lose faith. I’m convinced that the only thing that kept me going was that I loved what I did. You’ve got to find what you love. And that is as true for work as it is for your lovers. Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven’t found it yet, keep looking, and don’t settle. As with all matters of the heart, you’ll know when you find it. And, like any great relationship, it just gets better and better as the years roll on. So keep looking. Don’t settle.
… …
No one wants to die. Even people who want to go to heaven don’t want to die to get there. And yet death is the destination we all share. No one has ever escaped it. And that is as it should be, because Death is very likely the single best invention of Life. It is Life’s change agent. It clears out the old to make way for the new. Right now the new is you, but someday not too long from now, you will gradually become the old and be cleared away. Sorry to be so dramatic, but it is quite true.
Your time is limited, so don’t waste it living someone else’s life. Don’t be trapped by dogma — which is living with the results of other people’s thinking. Don’t let the noise of others’ opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.
… …

========== 我是可爱的分隔线 ==========
附:一个听来的八卦。iPhone 第一代出品之前,位于 Cupertino 的整个研发中心大楼是全封闭的,哪怕乔帮主也不可以把 iPhone 带到苹果另外的楼。话说有一天乔帮主去那个楼玩 iPhone prototype,有个工程师上去对乔帮主说,这个 iPhone 设计有问题,耳机插孔不是 flushed 的(背景知识:第一代 iPhone 耳机插孔较深,一般的耳机插头插不到底,而苹果自己的耳机可以)。乔帮主瞪了一眼那个工程师,怒道,但是我们苹果有世界上最好的耳机,不是吗??
这件事情说明了几个问题:1、乔帮主是一个排他性的完美主义者;2、乔帮主很和气,可以随便搭话,有问必答,不会石沉大海;3、不要随便和乔帮主搭话……
有关用电
November 16, 2008 12:59 pm GMT-0700 | In Life | 8 Comments | hide作为一个数字男,每天出门的时候拿手机给电表照张相(像右图这样),这样过一段时间就能拿来琢磨琢磨了。由于照片会自带 Exif 时间戳(同时可用来校正每日拍摄时间不同造成的误差),电表读数则可以通过图像识别或者直接肉眼快速读出,因此整个统计过程几乎可以全自动处理。下面这个图是统计出来的每日用电量。总的来说,还是比较稳定的,最后这六天在外地,果然省电……
昨天刚跨进家门就给 delphij 打电话,delphij 就我最近不及时更新 Blog 的问题表示了担忧。因此我今天更新一篇滥竽充数的,给伟大的 delphij 请安。

吊车工
November 8, 2008 10:40 am GMT-0700 | In Life | 5 Comments | hideMcKinsey 在 What we look for in a resume/CV 里面这样说到:
Similarly, you should include leadership positions, significant involvement in extracurricular activities, and significant participation in sports, games, societies, or hobbies. For example, a high level of achievement in a sport tells us something about your commitment and drive to achieve. Don’t just tell us about your hobbies; tell us what you have achieved in pursuing them. Generally you should only include items that you feel will help us understand your strengths better (rather than including something just for the sake of having it).
于是我在简历里面写:“能熟练操作起重 40 吨的吊车”。结果我的面试往往是这么开场的:面试官从一堆纷乱的文件里面找到我的简历,疲惫不堪的坐下用 10 秒钟扫视一遍,突然两眼放光的指着我说:“啊,我知道了!你是那个会开吊车的!”
你是那个会开吊车的!
你是那个会开吊车的!!
你是那个会开吊车的!!!
另一则:面试官问我们的引力仪什么精度,我说,如果您站在旁边,我们能测出来,当然,您要够肥才行。然后,我们俩同时狂笑……我脑子里面这时候闪出一句话:“Rule number one, never insult the interviewer. [1]”
