1. Magic! 1KB JavaScript code written by 3D bees

I believe a lot of net friends remember last year CSDN reported the same 1KB JavaScript code written by the 3D Rose, or 2010 years of 3D Christmas tree. Careful netizen may notice, these two magical works are the Spanish developer Román Cortés in the js1k contest, this year he brought the same magic 3D bee-long tentacles, tie.

Due to js1k rules, the work only supports Firefox 18, Chrome 24, and Opera 12 and 13. If you have installed the above browser, you can choose to view the online demo.

The implementation of this work uses many algorithms and rendering techniques, and the authors explain their technical principles in detail on their blogs. The source code is as follows (compressed):

2. The Father of Warcraft interview: This year the game industry will be a revolution

Through an accidental opportunity, krisviceral.com the owner of Warcraft's father, Patrick Wyatt (Pat) an interview. In the interview, Pat said he was more proud of the Guild War than Warcraft and StarCraft, because the game was not developed as hard as the previous two, and has also succeeded in exercising many new developers.

Patrick Wyatt (Pat) has been Blizzard Development & Search Vice President, participated in Warcraft, StarCraft, Diablo, Battle.net, Guild Wars, and other products development, CSDN has also written about his Warcraft, StarCraft development process related blog post compiled and reported. In this article, from krisviceral.com Bo Master kviceral to Pat's interview, Pat on the game, AI, software development and other aspects have expressed their views.

The Father of Warcraft, Patrick Wyatt.

You've been involved in a lot of popular game development work, which one of the most proud of you?

Pat: This is a difficult question to answer, because every game is devoted to my efforts. It really should be Guild War, which is our success in small teams.

We created a new company (ArenaNet) from the blizzard, built this very innovative game from scratch, and didn't even work hard to get overtime, but in the end we succeeded.

In ArenaNet, we recruited a lot of newly-graduated students, so many of them didn't know how much the development process of Guild War was different from "traditional" game development, but I'm glad they didn't have the same perennial crunching as most of the people in the industry.

When the

Guild War was developed, we were the only commercial MMORPG (large multiplayer online role-playing game) that gave up the subscription model (by paying a monthly subscription fee for unlimited gaming), and you can play indefinitely after you buy the game.

What's your favorite game in the last 2-3 years?

Pat: I'm enjoying Dayz's zombie theme game, and I'm amazed that I've enjoyed this game, and creeping on the ground for 10 minutes doesn't sound like a good idea, but the background of the game will make you crazy! I also occasionally play League of Legends, also very like Kindom Rush (Iphone/ipad) the Warcraft and StarCraft influence of the tower defense game, I and my children are very fond of playing. Recently I also found Airmech, is a good game.

What do you think is the biggest innovation in the game world in the past 5 years?

There is no doubt that the great success of the "Free Game" business model in the Western market has changed the way games are developed. Designers need to be more committed to creating fascinating experiences to keep their long-term stickiness to the user, but the downside is that some designers are using their creativity to get users addicted to the game or other "dark skills" rather than adding to the fun of the game. I would like to use "psychological manipulation" and other "dark skills" of the game will be fewer and less.

The other is the mobile game. Creating fun but Low-cost Games is very commendable! Recently, I found myself playing mobile games much longer than the PC host game. I believe that as game designers are more adept at using the small screen of mobile devices, they can bring us more outstanding works. >> View the original

3. Review: Third party applications blocked by the platform side

An application from the bud to the final real line, the period to experience all kinds of hardships, not very easy to launch, but also to be the platform side of the obstructive. If your application does not conform to the platform's developer agreement, it will be blocked. What about the efforts that have been made before? short In this paper, some typical cases of being blocked by platform are cited for reference only.

No.1 Adblock Browser plugin blocked by Google

Event playback: In March 2013, Google removed a very popular application Adblock Plus from its App store, Google Play, and several other applications related to shielding advertising.

Official reason: The Adblock Application violates Section 4.4 of the developer deployment Agreement: "Unauthorized access to other services or products is prevented by the use of unapproved means".

Developers complain: "We know that advertising revenue is important to Google, but Adblock plus does not automatically block all ads, but lets users choose to shield or not Adblock," said Till Faida, founder of the company.

Comment: Google is advertising to make money, and Adblock Plus plug-ins can shield ads. To be frank, Google's move to this application is now a surprising place.

No.2 Vintage camera was killed by Facebook No.3 third party image hosting service Twitpic, Yfrog was deleted by Twitter No.4 third party payment was blocked by Google Play No.5 Dropbox SDK application by Apple under the No.6 fawave, micro-bo, such as Sina Weibo Third-party applications were blocked No.7 Emoti for Facebook was deleted by Facebook inexplicable

As a netizen said: There is no real open, there is no real fair competition. The platform will always have one vote of veto power. So how can developers move ahead in the lurch? How to avoid the platform side of the "not to see" it?

The author thinks, the platform side and the developer "friction" is nothing but tort or dividend not all caused. How to draw this "red line", Taobao VP Wang Wenbin's answer is very representative, after he received an interview with CSDN reporters on how to view the platform and developers to benefit from the question said: Define what is the official basic tools, which are third-party tools, it is difficult to draw a clear line, there will be some vague areas. It is important to emphasize that Taobao does not want to compete with developers for profits to eliminate third-party applications. Taobao more concerned about the user data on the platform security and privacy can be guaranteed, user experience can improve, Taobao want to see the platform of Third-party manufacturers bigger and stronger.

4. Fly a letter head-on confrontation with micro-trust, users can buy?

An accidental leak in the mobile internal PPT not only stirred up the communications and Internet industry a pool of spring, but also disrupted the heart of the relevant companies. China Mobile wants to reconstruct the letter, the Development and Reform Commission said to the micro-letter to charge, then users can buy it?

Flying Letter is a comprehensive communications service launched by China Mobile in May 2007, that is, fusion voice (IVR), GPRS, SMS and other communication methods, covering three different forms (full real-time voice service, quasi real-time text and small data traffic services, Non-real-time communication services) of customer communication needs, Realize seamless communication between Internet and mobile network.

Micro-letter is Tencent on January 21, 2011 launched a fast through the network to send voice text messages, videos, pictures and text to support many people chat mobile phone chat software. Users can use the micro-letter and friends to form more rich similar to text messages, MMS and other ways of contact. Micro-credit software itself is completely free, the use of any function will not charge fees, micro-mail generated by the Internet traffic charges by the network operators. Micro-letter is a faster instant messaging tool, compared with the traditional way of communication, more flexible, intelligent, and save charges.

2007 China Mobile launched the chat tool, has been 6 years of flying letter software, because of communication with the SMS business is widely concerned, but the situation is not optimistic. According to statistics, now the number of users of the letter is not Tencent QQ One-fifth, the average monthly use of less than one-forty fifth of the latter. Even more so the fear is that, in the 2012 China Internet Conference, Tencent CEO MA in micro-blog announced that the number of micro-letter users has reached 200 million, as of January 2013 registered users have exceeded 300 million. This is the birth of only 2 years of mobile chat software, the development of such a rapid, so that the industry is quite shocked.

Micro-letter because of its easy to operate, can make friends, become a young man's tool for making friends. The initial micro-letter to the text communication, mobile phone photo sharing as a selling point, in the late development process to find "Look around the people" and "shake" the function is more popular with users. The number of new users on the micro-credit day increased by hundreds of thousands of, establishing its absolute dominance in the mobile app market.
