My Love on Vim

My life with Vim I started learning Vim during Aug, 2011, the original motivation was trying to "get rid of my mouse while I am coding", I had no teacher but google, learnt it from the very hard way. From the beginning 2-3 months, honest speaking, I was less productive while using Vim comparing with IDEs, there were so many things I could do in second in IDE, for example: search/replace, formatting, re-factoring, folding, and so on, whereas I had to spent days in learning how to accomplish a simple task in Vim, that was really painful, but I never gave up! After the first two months of e...

Setup MongoDB with sharding infrastructure

The landscape  Sharding is the strategy that MongoDB uses to horizentally scale the entire data store infrustructure and meet the demands of data,growth, the infrastructure can be demonstrated as image below: Preparation To simulate a production like environment, a minimum number of 7 physical/virtual servers are required, the role of them are: 3 for Mongo config servers 1 for Mongo shard server (mongos) 3 for a Mongo shard (Replica set), 1 primary and 2 secondary (or 1 secondary and 1 arbiter). Note: all the machines above need have mongod installed, for in...

WTF?IBM Lotus and Domino Server?

Technical tags: IBM, Domino, AIX, LotusScript, ODBC/JDBC, ADO, OLE DB, Assume we are now in Jurassic period, the technologies above are in Cambrian period, developers who has less than 4 years experience probably never heard about any of the above terminologies... No choice, I was dealing with them during the passes few weeks, I met ODBC as soon as I graduated while I was development ASP website using VBScript, but it was soon replaced by ADO, and after half a year I started studying .NET so I used ADO.NET, nowadays we usually talk to Entity Framework which abstracts ADO.NET interfaces...

Cache Reverse Proxy - Varnish

Introduction Varnish is an HTTP accelerator, the official page is: Varnish stands in front of the web application server to be a cache reverse proxy (also can be a load balancer), it can simply cache all the static resources in memory, and can also be powerfully configed using VCL (Varnish Configuration Language, a DSL for Varnish configuration) to cache dynamic content, in addition, Varnish implements ESI (Edge Side Include) standards to provide ability to cache static parts of the page.

Cache Reverse Proxy - nginx

Introduction On the homepage of nxing wiki, there used to be one sentence which really impressed my very much when I first time to take a look at it and learn it three years ago: Apache is like Microsoft Word, it has a million options but you only need six. Nginx does those six things, and it does five of them 50 times faster than Apache.  --Chris Lea

12 tips to boost RSpect and Cucumber

In our daily TDD/BDD work, we spent most of our time in test cases, we analyze requirements, write test case, run it and watch it fail, implement code to make the test pass, repeat the process "until money runs out". Thus the speed of running those test cases have significant impact on a team's performance, ! You can't tolerance writing a test case, waiting 1 minute finish; You can't tolerance CI finishes running all RSpec/Cucumber tests for half an hour! I can't! So I motivated to improve this! The result

Resolving mouseover/mouseout multi-trigger problem

Background While I was developing my blog's comments function, I hope reader can write down their Gravatar email address, and my preferable UI was an "hint icon" dispolayed desides the Email textbox, so that while reader mouse overs it an overlay box will show the reason why Email is required, in additional, I want to add a little bit fancier animation: When user's mouse hovers on the icon, show the div box from small to large, once reaches predefined size, fades in the hint sentente. When mouse out the icon, fades out the hint sentence and then hides the div from large to small. My ...

Modify proxy settings using Powershell

To use Live Messenger in the office, I always need to firstly disable my proxy settings, after Live Messenger launched, I need turn it back. Thus everytime I need to change that from "Internet Options -> Connections -> Lan Settings ->", check/uncheck the checkboxes, well, this task I need to do at least one time a day, I as a developer should achieve this in a more efficient and convenient way. By overcoming one problem I wrote a snippet of Powershell cmdlet which does the job perfectly, the steps are: Update proxy settings to "Automatically detect settings". Launch Live Messenger...

Windows 8 - Far from perfect

Recently I spent a few days in investigating Metro App (AKA immersive UI) development, I downloaded & installed VS 2011 Ultimate, watched couple of videos talking about WinRT, Metro App life cycle, Living tiles & Notifications, etc. So far, I've encountered many many issues...

Honored to Win CodeProject HTML5 competition

Three months ago, my article <HTML5 WebSocket In Essence> was honored to be named first prize in CodeProject HTML5 & CSS3 competion, the award was an Ipad2. To be very honest I was expecting to win a T-Shirt or a CP Mug, if I could get either on I would be really excited, so when I received the email congratulating me I was the winner, you can image how excited and happy I was at that time. However, the editor from CodeProject told me they were unable to ship the Ipad2 to China, they could give me equivalent money - $499.99, however after a very short consideration I decided to ta...

Make your HTML5 Video support all browsers

Introduction HTML5 video tag gave us the following advantages: No plugin required, directly play. Visible & controllable for Browser and search engine, not a "black box" such as Flash or SilverLight. Cross-platform, in theory all PC/mobile browsers as well as Ipad/Windows 8/Android tablet PC.  Downward compatibility. Which is very important, but W3C had made it simple and works, we can smoothly fall back to flash if the user agent does not recognize "<video>" tag. So it is simple and pretty cool! However, there is still issues within a not short period: the browser support ...

Atomic Operation in C#.Net

Introduction Atomic Operation is named academic to Linearizability, Atomicity is a guarantee of isolation from concurrent processes, it can be enfored by hardware level build on Cache Coherence protocol, or software level exclusive lock.

HTML5 WebMessaging In Essence

Download - 2.97 KB As a web developer, sometimes we are easy to encounter one problem: Cross-Domain communication, conforming Same-Origin-Policy, JavaScript code cannot access code stay in different domain(or sub-domain) or protocol (HTTP/HTTPs) or port, so there was no direct (or I can say: simple) way to achieve Cross-Domain Communication. However, those kinds of requirements does happen: page A and page B are in different domain,  B is "embedded" in A, i.e., there is an "iframe" in page A whose "src" is page B's URL, now page A want... on Ubuntu 11.04

JavaScript - Foundation of the Language

Introduction JavaScript "was born under the shadow of Java" - Brenden Eich, it is "the most misunderstood programming language in the world" - Douglas Crockford. JavaScript was used so widely nowadays, nearly everywhere as long as you are using a web browser and surfing the internet, most of the websites have JS inside, and even server side - nodejs, according to, JavaScript is the fourth popular programming language in the world.  In this post I am trying to use refined language to cover some foundation of JavaScript (many of which con...

Exception handling particulars in C#

Background Exception handling appears in most .NET applications, this post is trying to describe some  Exception handling particulars in C# which might not take enough awareness from C# developers.  Differences between throw and throw ex  I guess every C# developer has seen code snippet below: try {     // Do some work, exception occurs } catch (IOException ex) {     // Exception caught, re-throw it to bubble up     throw ex; } In the catch block, we can rethrow the caught exception instance of IOException to higher level, an...

AJAX Cross-Origin HTTP request

Background Cross-Origin Request Sharing - CORS (A.K.A. Cross-Domain AJAX request) is an issue that most web developers might encounter, according to Same-Origin-Policy, browsers restrict client JavaScript in a security sandbox, usually JS cannot directly communicate with a remote server from a different domain. In the past developers created many tricky ways to achieve Cross-Domain resource request, most commonly using ways are: Use Flash/Silverlight or server side as a "proxy" to communicate with remote. JSON With Padding (JSONP). Embeds remote server in an iframe and communicate th...

HTML5 Web Storage in Essence

Background Web Storage (also named Dom storage) is a brand new mechanism of storing temporary/permanent data introduced in HTML5 to replace cookie, it contains two new DOM objects: sessionStoragy and localStorage), in Web Storage Spec, Ian Hickson documented that Web Storage are intended to solve two cases that "not handled well by Cookie", they are: The first is designed for scenarios where the user is carrying out a single transaction, but could be carrying out multiple transactions in different windows at the same time. The second storage mechanism is designed fo...

HTML is the new HTML5

Few days ago Ian Hickson wrote a blog: HTML is the new HTML5, he referred "we moved to a new development model", and comes with two major changes: The HTML specification will henceforth just be known as "HTML", with the URL The WHATWG HTML spec now became "living standard", "It's more mature than any version of the HTML specification". I took a screenshot below: In a simple sentence: HTML is going to "unversioned model", according to this there is definitely a concern: OK, living standard? Does this mean the standard could be changed/updated/revised at anytime?...

Unique URL Pattern in Ajax Web Application

Testing: Can I really edit this? Background Few days ago one of my friend asked me how does Gmail change its URL while user operates inside it without page refreshing, I’ve no idea about that at that time, he then shared a link Ajax Pattern - Unique URLs which deep dives into this topic, as the article mentioned: Unique URL make your website’s link “Bookmarkable, Linkable, Type-In-Able”, plus Sharable IMHO, easy to be shared to Social network which is extremely important nowadays. Implementation The key technology to achieve the ““Unique URL” goal could be summarized into two points: If t...

IP Address to Geolocation

Background Few months ago I found an interesting website:, it provided API which could “translate” any IP Address into a geography location including City/Region/Country as well as latitude/longitude and time zone information, to invoke its API, a registered API key is required (which is free). Since beforehand I stored visitor’s IP Addresses into my own database, I decided to utilize InfoDB API to store visitor’s GEO locations. Just few days ago, I casually emitted an idea: summarize those GEO location records and display them on Google Map, hum, it is feasible:) So, ...

Utilize gzip compression in IIS

GZIP format is developed by GNU Project and standardized by IETF in RFC 1952, which MUST be considered by web developers to improve their websites' performance, there are several Quintessential articles documented using gzip compression, they are: 10 Tips for Writing High-Performance Web Applications Best Practices for Speeding Up Your Web Site How To Optimize Your Site With GZIP Compression IIS 7 Compression.

A complete Impersonation Demo in C#.NET

Under some scenarios we need impersonate another Windows account and do some work under that user’s session, for example: An enterprise ASP.NET web application provides server administrators’ ability to access the server under some specific privilege set; Server admin input their NT account information (domain\account + password) on the page, we need get WinNT Access Token and then impersonate this server user, so that we acquire its specific privilege and do the things ONLY THIS ACCOUNT CAN DO. We developed a Windows Service which needs internet access periodically, but a specific user ...

Programmatically PIN shortcut onto Taskbar on Win7

Background During my work I got one requirement of pinning a specific shortcut file (*.lnk) onto the Windows 7 Taskbar, after investigating I found programmtically achive this is “not permitted”, refer MSDN article: A small set of applications are pinned by default for new installations. Other than these, only the user can pin further applications; programmatic pinning by an application is not permitted. However, the exception comes from Windows Script Hosting, a snippet of VBscript can achieve my requirement, I read severa...

Encrypt .Net Configuration file

Under some scenarios the developers want to encrypt some sections inside app.config or web.config file, this article How To: Encrypt Configuration Sections in ASP.NET 2.0 Using RSA describes how to do so clearly, Scott Guthrie also posted one: Encrypting Web.Config Values in ASP.NET 2.0. However, in the posts above they uses aspnet_regiis.exe and seems it doesn’t directly support app.config, if we want to encrypt app.config for Windows Form or WPF applications, while I tried use it to encrypt my app.config file, it generates a web.config which means my Winform definitely can’t use it, even...

Personal Schedule Management Tool

Time is always ticking no matter you care it or you don’t care it, everyone knows it including myself, to remind myself don’t waste too much time on gaming, reading news or something else, I developed a little tool which I call it “Personal Schedule Management Tool” to achieve this simple goal. Mechanism I create an XML file to store a serial of [time stamp/task to do] pairs, the tool will start with Windows and load the XML file, a working timer behind it will periodically check whether there is a task needs to be done at defined time stamp, once the condition is matched, the tool will ...

A good lesson and experience

I was extremely busy during the last two weeks, since our project was at bug fixing phase, my team and I worked really hard on dealing with the bugs; We fixed two to three bugs everyday by average, I am very satisfied with the efficiency myself. During this process, I encountered several very interesting issues. There was a crash bug with P1 priority, we all cannot reproduced it until one guy from US team provided a remote server that our product always crashed, after I logged onto that server and 20 minutes investigating, I was really surprised, the reason is one line of code written by ...

作息时间自动提醒Windows Service

前几天在网上找到这么个酷酷的玩意,用JS给图片加上各种各样的圆角效果,官方主页: 看后顿时觉得很酷,今天周末,有时间来搞搞这个:) 读了官网的说明后发现很简单,下载corner.js(本地下载 ),然后页面include后直接使用class="自己挑一个喜欢的class"就ok了。 那么这里有个问题,如果你的Blog上线已有时日(比如鄙博),难道要手动更新你之前所有Blog里的图片代码给它们加上 class?? 呵呵,这点事根本不能称之为问题:)当然是加段JS脚本给动态注册className喽,鄙播采用了Div+Css架构以及 MasterPage,所有的Blog都包含于一个名为“ContentPlaceHolder”对Div中

这几天研究Url Rewrite:)

在开发这个自己用的Blog时,决定认真研究一下以前接触过的URL Rewrite,我见过类似这样的域名:,一直不知道怎么实现的,正好借这次机会研究一下。 从前天开始就一直在努力,基本上是第一天差了大半天资料,这篇文章写得非常详细,向作者致敬!第二天终于上手做出Demo,但有Bug,第三天解决了Bug,完美运行^_^ 其实简单点说,个人觉得对于ASP.NET开发者实现URL Rewrite基本有3种途径: 1. 修改IIS ISAPI扩展,例如把”.xx”交给aspnet_isapi.dll ISAPI 扩展,就成了这样:”xxx.htm?q=blah”,这样就是最简单直接的SEO,但由于我是虚拟主机所以我仅仅只在本地试了下,不知道精英科技的管理面板是否支持,我没有试。2. 修改WebConfig,添加

BMW Convertible As My Beater Car

Life is too short to drive boring cars I bought a 2015 BMW X5 Dec last year, it has been half a year so far (with 2 months she stayed inside the garage for most of the time due to the pandemic), I am pretty satisfied with it, her condition is absolutely excellent, everything works, yes you see it correctly, after 5 years of its life, there was nothing broken, as BMW vehicle built in recent years, this is something not VERY easy. My plan is to keep it as long as possible before it turns into an endless money pit, and keeping her value as high as possible, one of the major reason I b...

Ireland Trip 2019

WHEN YOU ARE OLD When you are old and grey and full of sleep, And nodding by the fire, take down this book, And slowly read, and dream of the soft look Your eyes had once, and of their shadows deep; How many loved your moments of glad grace, And loved your beauty with love false or true, But one man loved the pilgrim soul in you, And loved the sorrows of your changing face; And bending down beside the glowing bars, Murmur, a little sadly, how Love fled And paced upon the mountains overhead And hid his face amid a crowd of stars. – By William Butler Yeats 当你年老时     ...

Apply UK Visit VISA

Background I was planning to attend #adskfootball2019 in Dublin, Ireland from Jun 14th to Jun 16th, 2019: Autodesk Football Tournament 2019 In order to attend, I needed applying Ireland VISA, and since I was planning to fly back to Shanghai later in June, so I thought I could just fly from SF to Dublin, then Dublin to Shanghai, and soon I realized that there is no direct flight from DUB to PVG, so a practical (and also very fun and economic) option is to fly from Dublin to London, and then London to Shanghai, bingo ^_^

FC Barcelona Miracle Comeback!

一个月了,基本上都习惯了,衣食住行,文化,交流,觉得适应得还行吧,零零散散的想记录一下平时的所思所感。 食:首先当然是吃饭问题,民以食为天,饭吃不好那问题可是大大的!吃的最多附近的当属汉堡了,大口大口的,呵呵。想起第一次吃汉堡是90年在北京,我们一堆小屁孩一人发一个麦当劳的牛肉汉堡,我们都实在无法忍受两块“面包”中间的那“坨”肉饼,无论是视觉还是味觉都从心理上第一时间抵制了,总之大家都扔了,只吃“面包”和薯条。之后从不太厌恶变成现在的还有点喜欢,隔段时间也许还想啃上一个(比如上海的汉堡王鄙人就比较喜欢,呵呵),临走之前Monica说那个(叫什么来着的店,不记得了)有70块大洋的一个巨大汉堡,比较感兴趣的说,一直想去吃呢。。。那么来美国一个月后,我对汉堡的认识是更加深刻了,每天中午去微软的食堂,对我来讲基本上只有3.5种选择:1. 皮萨2. 汉堡3. 沙拉3.5 每天变换的汤 汤由于不能解决温饱问题所以算0.5个好了,皮萨最简单了,就躺在那,铲一片走人,直接买单(2刀),也是最便宜的了。汉堡呢就有很多选择,Turkey burger($3.10), Angus Burger($4.15),Blah Blah Burger(最多7刀,猪鸡鱼牛都有,名字太多太复杂不记得了),我老是吃Turkey burger,真可怜呵呵, ok,说下汉堡是怎么做成的,鄙人原来是不知道的。先跟厨...

人生中那些重要的第一次 - 塔科玛机场见闻

这个时候我已经坚持了十几个小时,人昏昏沉沉的,但是。。。要面对边境检查,还是得打起精神,这是第一次,所以没有任何经验,我心想:“别搞得折腾了半天挂在检察官手里让我回家,机票他报销。。”,呵呵。 在等待过边检的时候看到一张宣传图,上书:“Keep our doors open and nation secure.” 赞!!! 我的理解是: 我们欢迎人才!在保证国家安全的前提下! 不拘一格降人才! 在过去的一个多世纪里,美国宽松灵活的移民政策在很大程度上保证了这个国家领先于世界民族之林。 不过近几年呢,尤其是911之后,老大很受伤,变得相对谨慎。。。很多仁人志士对此颇有微词,比如比尔盖茨。 正思考着呢,轮到俺了。Check我的检察官是个黑人,问了些问题,现在只记得问有没有带食物,我回答没有,之前在飞机上韩国空姐给的单子上我也填的没有,我觉得我带过来的那一箱热干面应该不会伤害山姆大叔的农民伯伯吧:)我的邀请函上只有26天,我的PM让我要3个月,那么在检察官问我时间时我跟他说:请您给我3个月,因为培训已经延长了。他没说啥,就一个劲的在那里盖章,好多章要盖!大概有20分钟吧,ok了,看到同事已经在等我了,发现自己已经汗湿了,没办法,里面有点热。 <P>随便拍了张</P><P></P>

人生中那些重要的第一次 - 仁川到西雅图塔科玛

到这边以后忙着倒时差熟悉工作和联系家人了,没空写部落格里,今天稍微闲了点,爬上来继续记录人生中最重要的第一次:) <P>——————正文——————-</P><P>这趟9跟小时的旅途着实辛苦,虽然无论是航空公司还是我自己都做好了各种消遣的,不可谓不完善的准备。</P><P>我的装备^_^:</P><P>PS2手柄还没照出来的,放脚下了,空间太小实在不可能放上面,</P><P>大韩航空公司准备了一高科技玩意,我一坐上位置就研究上了(没办法,谁叫俺没出过国呢,乡巴佬一个。。),就是这玩意: </P><P>呵呵,玩游戏的手柄,这是背面,正面是另外的一些功能,有:电影(比较多,各种类别的,我看到有国家宝藏2算最近流行的),CD音乐(我基本上只认识Celine Dion,见下面一点;靠!再怎么着也得有Linkin Park吧?!),航班情况(动态显示飞机在地图上的位置,跟上篇里的差不多),免税信息(高丽棒子赚钱用的),儿童乐园(俺是成人,不玩),等等等等,不记得了。。。飞机上一旦有广播,它就会自动

[转]揭秘朝鲜自主操作系统:红星Red Star

据国外资讯网站RT报道,朝鲜(North Korea)不仅拥有自主的、与基于美国的万维网相互独立的区域网络,而且还拥有自行研发的红星Red Star操作系统。据悉,红星OS是去年由朝鲜IT技术人员在Linux操作系统的基础上改进而来的。俄罗斯学者Mikhail利用他在金日成大学交流之际获得了这款红星OS。他花费了5美元在距离宿舍五分钟步行路程的地方购得两张安装光盘。系统共分为客户端和服务器两种版本,第三方软件可以另外花钱购买。 废话不多说,下面就让我们一睹为快:   1、拆包后的安装盘,上下共两张; 图(1)   2、启动Logo画面,红星OS支持硬盘或网络下载安装,整个过程约为10-25分钟。启动安装程序后,用户会发现整个过程与Windows十分相似,但更加快速、简单,而且只有朝鲜语一种语言版本; 图(2)   3、登录界面:默认为Root用户名,右侧的Lim是游客账号; 图(3)   4、Red Star桌面

Storage+Media home server for less than $300

Background I have been researched and watched many NAS options to setup a home storage+media server during the past year, and so far there was no perfect answer, either lacking features/performance, or way too expensive… An Intel Celeron CPU + 1GB mem with a customized Linux (in other words: closed source )running Plex or something else, and the cost is like $400 (terrible hardware performance), or $800+/$1000+, way too expensive, examples: Synology DS216J NAS DiskStation (DS216j) WD My Cloud EX4100 Diskless Expert Series 4-Bay NAS NETGEAR ReadyNAS 524X High Performance 10GbE 4-bay...
