最近又再次沉迷于SUDOKU。

 

最早接触数独与马尧的一本数独书有关，应该是大三上的事了。那时候完全入门派，逻辑走得少，分支猜测走得多，所以一道题下来往往是每一个空都擦了N多次。

数独的深入接触应该是在大三暑假和大四保研考试前。当时回访一清华朋友Blog时再次发现对数独的介绍，那个亲切啊……第一时间就在网上开始奋斗了。这次由于认真做了很多题，整个逻辑关系已经理得比较清晰了，所以hard几乎能搞定，hardest能搞定一些但速度不快。一种久违的成就感油然而生，也许确实是这个游戏的魔力，也许是天生的数字热情……高中以来就很少接触数字了，现在想起来，高中时在数学上颇多建树，大学四年却极少与数学打交道，总有种怪怪的感觉。

最近再次进入SUDOKU状态。做的hardest越来越多，数字逻辑把握的也越来越多，于是开始佩服发明这个游戏的人——一个规则如此简单的游戏，竟然蕴含了数十种逻辑。而所有逻辑算法的叠加，能够保证一道即使是hardest的SUDOKU的解法，也绝不包含任何猜测和假设成分。

数字的魔力……

 

The rules of Sudoku are surprisingly simple. Just Count to Nine!

Every column, row, and 3×3 square must contain the numbers 1 through 9 exactly once.

Every Sudoku puzzle has exactly 1 solution that can be solved logically without guessing.

规则就这么简单——来解题吧。

建议从hard做起……

 

无意中翻出一张诡异的照片——保研后的一次饭局照的。

惊闻又一儿时好友买了NOKIA的N70，投入Symbian阵营，自觉羞愧万分。那可是从幼儿园时就一同调戏良家妇女的顶级狐朋狗友，居然在手机操作系统上再次误入歧途。呜呼哀哉，作文以记之。

下面将把本人在IT领域的毕生绝学和所有感悟奉出，其对汝等指导意义之重大，不可谓不惨绝人寰。

 

①手机的操作系统

这当然仅仅针对智能手机（还没换的快换吧，最便宜的几百块就能搞定），现存的OS主要有三：Window Mobile、Symbian和Palm。Palm是开山鼻祖，可如今已到末年，好像只有Samsung（本人最为鄙视的垃圾公司之一）等为数不多的几家公司支持，可以说是必挂。Symbian是虾米东西呢？是以NOKIA牵头的几个手机制造商自己做的操作系统，系统之垃圾可谓惨绝人寰（你想想，几个从未做出系统的公司能做出个什么系统？），不过靠NOKIA在硬件的名声还保有一定的市场占有率。然后就是Windows Mobile了，这个才是王道，近年来市场占有率一直在升，最重要的是——与PC的兼容性，与Microsoft所有产品的兼容性。这可就厉害了，Windows Mobile有与Outlook一样完善的Contacts、Notes、Mail、Task、Calendar，有完善的Word、Excel、Power Point（Symbian也有，但很垃圾），有IE、MSN、WMP等等等等，最重要的是Microsoft在不断完善Windows Mobile与Windows的兼容性，也就是说，能实现“Smart Phone is not just a PDA, or PPC, it will be a PC tomorrow”战略的OS只有Windows Mobile。

我见过N多Symbian的机子，N部所谓Symbian的集大成者N70，可当我把基于Windows Mobile的软件show给他们看的时候，没人不承认WM才是王道。

NOKIA如果坚持自己走自己的OS路的话，只有自取其辱的。

 

②聊天工具

现存主要有QQ和MSN，次要有Google Talk、Popo、UC、ICQ等等等等。王道在哪里？

QQ虽然人多，可界面之乱那可不是一般化的，虽然有TM这种弥补产品。可回过头来认真想想，MSN上似乎都是VIP，有上司，国外的朋友，外国人等等等等，而QQ上大多是狐朋狗友（当然狐朋狗友也是重要人士，本人从来都极其器重狐朋狗友）。你是开MSN，还是开QQ呢？

Google Talk是新兴的，理工科牛人特别喜欢（清华的朋友大多对此情有独钟），最大特点是简洁，这也是Google的成功之道。

如果只让开一个聊天工具，我开MSN，如果让开两个，那我的选择会加上Google Talk。

 

③Blog

这可就五花八门了，什么sina、sohu、163、blogchina、blogcn一堆一堆的。王道在哪里？

结论是，在Goolge还没有推出Blog服务的时候，王道还是space。

为什么？兼容性。

至少我的手机能在不开通任何服务的情况下耗费低流量轻松浏览和修改space，而浏览其他的blog则必须耗费大量流量用手机上WEB。更有甚者国内的一些blog网站更是开通手机上blog的收费服务，我KAO，你压榨百姓还是骗你老母啊？

还有一个重点，Microsoft垄断的力量。

速度？校内网速度确实慢，等你毕业开宽带后速度就会好很多了。

 

④新闻

sina？163？sohu？yahoo？tom？抑或MSN那搞笑的“北青网”？

这些门户网站新闻的共同特点是杂、乱。新闻最重要的是什么？精、简。

因此Google又一次成了王道之选。

Google Personal，精简你需要的所有新闻到一个页面。更重要的是，Google有很人性化的手机浏览设定。我能够轻松用我的手机浏览我所设定好的新闻。

每天起床或者睡觉的时候躺着用手机看一下今日之要事，而这些category又都是自己选择的，爽否？

 

⑤Mail

Gmail主mail，163副mail，同时设定Gmail收到邮件自动转发163。

这是完美之选，不要问为什么。

Outlook收邮件已是过时之选，现在已经是网络时代，不是软件时代。

 

⑥Presentation

一般来说PowerPoint够用了，完美掌握它也并非易事。

Presentation实际上的王道应该是Flash，不一定用Macromedia Flash，DreamerWave大体就够用了。

另外记住，做PPT或者Flash重不在技术，重在艺术感，在创意，这是关键。

 

⑦图像和排版

图像：PS还用讨论么？

排版：Adobe Indesign 2.0，王道。

Page Maker？什么北大飞腾？还有那些我都没听过的国产排版软件？全是垃圾。

跟艺术软件相关的领域，没有比Adobe强的公司。

 

⑧股票

大智慧。国内深沪两市分析的王道之选。

 

⑨浏览器

IE纯搞笑，FireFox稍显变态。TT和Maxthon是王道之选。

 

⑩杀毒

Kaspersky，王道。不过不大适合笔记本用。Norton也不错。

瑞星？国内的毒专克国内的杀毒软件，你不知道？

 

先暂时10个，有点多。如果耐心看完的话，对你绝对有帮助。当你需要做出选择的时候，过来人会让你少走弯路。后面的部分没有详细写了，有兴趣的面谈。另外，如果是对手机软件有兴趣的，你更是找对人了。个人觉得，若干年之后，手机软件的重要性会超越PC软件的。或者说，手机软件就是PC软件了，二者融合。总之，懂点手机软件，不是坏事吧？

Cool iPod nano, the black one gave me quite a perfect impression. The only word I could say is COOL, nothing more. I don't know why I love black so much, black notebook, black mobile phone, black joystick and black iPod.

Only .27 inches thin and 1.5 ounces, iPod nano packs a lot into its diminutive design. Up to 14 hours of battery life. 2GB or 4GB of storage. A bright color display. The Apple Click Wheel. A Dock connector that fits an entire ecosystem of iPod accessories. With so many features like these, iPod nano can change the way you listen to music — and more.

Rumors have been rampant about a Motorola Smartphone in the RAZR form factor designed to take on the Tero 650 and BlackBerry devices head on. Well it's official now, the Motorola Q will start shipping first quarter 2006.

From the release:

The first no-compromises QWERTY is here: the new Q from Motorola. Smart, powerful, and devastatingly good-looking, the Moto Q is the ultimate power player. The world's thinnest, lightest QWERTY phone is a seamless fusion of QWERTY and phone delivering a fully-loaded package of email, voice, and entertainment in one amazingly rich but thin device. Like its cousin the RAZR, the Q's superior voice quality makes it a stand out from the competition.

Boasting flexible mobile email featuring Microsoft's Windows Mobile software, advanced cellular phone technology, rich multimedia capabilities and an easy-to-use one-handed navigation thumbwheel, the Moto Q is unique. An all-in-one handheld designed to deliver true seamless connectivity, the Q will help mobile professionals improve productivity through the power of seamless mobility.

"Wickedly cool when's the last time you heard those words used to describe a QWERTY device?" said Ron Garriques, president mobile devices business, Motorola. "Probably never. At least until now. With the Moto Q, we've combined the best voice, data and design technology in one ultra-thin, intelligent, hard-working, and incredibly must-have device. Today's office space has the potential to be any place you want it to be with Q."

Truly Flexible Email
The uber-intelligent Q leverages Microsoft's familiar and trusted Windows Mobile software and is one of the first devices to operate on the latest release, Windows Mobile 5.0. Motorola Q delivers scalable and cost-effective mobile messaging support out of the box with Exchange 2003, and is also optimized for a variety of third party email solutions that enable an even broader set of corporate email capabilities. This provides a cost-effective alternative for businesses looking to leverage their existing infrastructure, training and support systems, while reducing the need for additional IT investment.

RAZR-Sharp Looks & Entertainment
Fifty percent thinner than its top competitors, the lightweight Q features Motorola's renown RAZR-thin design including electro-luminescent keys and a compact "antenna-inside" shape. Moto Q also hosts a large, vibrant, color screen, Net surfing capabilities, a 1.3 mega pixel camera with flash to help you take advantage of any downtime with fun, entertainment options. No need to grab another device on the weekend when you can leverage digital video and audio capabilities, along with cool new Bluetooth -enabled accessories like RAZRWIRE eyewear, to balance work and play.

Best Phone Experience
But great email and good looks aren't enough. True productivity demands superior voice quality too something not always found in QWERTY devices. Leveraging Motorola's expertise in RF technology, the new Moto Q delivers the best phone experience you can get on a QWERTY. Featuring a high-quality speakerphone perfect for conference calls, voice-activated dialing, and Bluetooth functionality the Q enables hands-free multi-tasking for today's busy work environment.

So it looks like we're going to have to wait for this new device, but it certainly holds a lot of promise and with the success of the RAZR and the Treo 650, we should see it on multiple carriers, though it's expected to support EDGE, giving Cingular a clear lead as the premier carrier.
