"Editor's note" author Li Chen Lei Feng network, the Thunderbolt for 8 years, much of the work involved in the Thunderbolt member. Come listen to hit his Thunderbolt to do four things, those seemingly mundane and important details of the judgment, is one of the culprits of killing the project.
As a result of seniority in the Thunder a little bit for a long time, and participation as key members of a number of failed projects. After most projects fail, you pick up the mood change under a project to work, very few recalled the shortcomings. I think these failures than successes share stunning winning hand, more enlightening.
These items are dead, I should be able to have a peace of mind fails, it tries to write the lesson.
Data analysis
This is the first task I just graduated through a user-end of huge amounts of data to find thunder download speeds where there is a problem and wants to solve the problem.
Download speeds are strong indicators related to the local network, we're wasting a boss "a bunch of" paycheck, the most valuable results, that is: a new edition published in a unified network Environment speed comparison of the old and new versions, to get a real improvement of the report.
Really sounds like nonsense, but at the time we did not know.
I maintain the data in the report has a MP3 download speeds, my boss's boss's boss Li Jinbo Development Division four speed interval statistics, are: 2m, 2~5M, and 5~10m and 10m above.
Because is boring brush exists sense, one day I mail to Lee boss, in mail in the listed has detailed of information and statistics data, also plus has box figure and stems leaves figure, description MP3 main concentrated in 3M~8M, so we of download speed statistics divided should with 3M following, and 3M~8M, and 8M above this three a speed to difference, such on can compared real to reaction out user download Shi of feel.
After the message was sent, Jinbo find me eating lunch, said only one sentence: the index looking at historical trends, changes in this statistic is really important? And not say anything.
This lack of clear objectives, the company also lacks outputs the project over a period of time is natural because the members leave to dissolve, I had Thunder members work just because perhaps by chance.
As a result of this experience, I know a bunch of people on the team have contributed nothing to pretend to work, and also some seemingly professional report to paint the presence (because that's what I play).
Later I team students graduate to a new company, I will refrain from hiring the idea, some people can digest good extra work. Results are often less, thing that can continue to operate. Starbucks iPhone 5 Case
Offline gold bean
This is made Thunder I Member one early work. Starbucks iPhone 5 Case
When I first started doing offline download, because our cost estimate has no bottom, plus some technical bottlenecks, we give very few paying customers offline space (if VIP1 is 3GB, single 1.6GB max), high speed accelerated channel flow on a monthly basis the total file size is less than 10GB.
(Thunder offline soy beans)
Although our background statistics 99% enough for all users, but it is absolutely not enough to download enthusiasts. The mainstay of these enthusiasts and just pay us.
So we want to have a look at that time was an ingenious plan. We had a user conversion, high-speed channel flow in 1GB room =1G/day = 1000 silver = 1 gold beans beans.
User can save each month without traffic and space, just in case one day when I want to download huge files, it can come in handy. Further, we also wanted to give their unused beans to a friend, or interact, generate more value.
My storage space is 3GB, when I want to download a collection of 30GB island country melodrama, can do about it. But with this golden bean conversion system, I 3GB a month of space can be converted into 90 Golden beans and beans with 30 gold exchange 30GB day.
Because basically leveraging future Golden bean, 29 days left I can only have 1GB in space.
You see the problem yet? The conversion is so complex, most people simply don't understand. Users tend to be in space when an overdraft, then no problems after careful consideration, less space.
Suddenly to a lot of things very happy, then discover what happened in a few days, my space is gone do? When recovery? My space is less indefinitely? Careless mistakes do? Since when is one day? My own count and you don't?
Oh, a series of questions, just online I'm part-time answering questions every day of the week, peak times 1000 users per day strengthen our external QQ ask, or swearing.
Originally wanted to help users solve the space problem for downloading larger files, resulting in a foul. Later on QQ cyclone offline download competition and our declining marginal costs, growing to user space (1000TB, is the TB was right), has not finished. Golden bean this feature is no longer necessary.
At one point, temporary supports offline Lu Wenjin class at design time to take off the Golden bean display and operator. In fact, I know this stuff has no value, but the devil is not dead, ask why he didn't.
Just turned me into a sentence: the bean is not important, the interface there is no need in such a small space.
We want to solve the problem of user space and cost controls, but we want to be lazy energy-efficient, not to technically reduce storage costs, not to develop the user reduce the marginal costs of these "stupid" instead of pursuing a kind of manipulative skill.
Not from the sustainable, active upgrading us, not upgrade improvement (improvement) to solve the problem in terms of really stupid.
Moreover, when so many users (thousands a day) complaint or demons don't die, keep fixes, tactical diligence our strategic mistakes, won't admit you, misleading false positives.
File mail
New features for some time a member has been out, so the big boss in the United States called "you send it" after the company got a round of financing, we make one.
You send it solve the problem of the companies receive large attachments mail through Outlook to install a plugin, do you send large attachments automatically converted when you send it a download link. Somewhat similar to the QQ file transfer station, just more business applications.
As we all know, boss of the project, we must actively respond to rapid product. So we are imitating you send it's basic features, released a game called "file-mail" product.
(Thunder file email)
Users to upload attachments, enter each other's email address, you can send big files to each other. If this file (such as island country melodrama) Thunderbolt server has cached, you can achieve instant mass greatly reduces upload time.
Sounds a bit like it.
Funny fart!
My biggest problem was it trying to clean it as a product, by his patience to build, was not considered an important issue: the Chinese people there are very few people who can remember each other's mailboxes?
I want to friend's mailbox but QQ personal message inside to check, or by copying his QQ number. Since I have QQ, simply use QQ file transfer stations are not on the line, fast and good. Also need to post the broken file where stuff here.
So we won't admit you to release several versions, the number in use is our own, after the test, finally ran aground.
Later, in Lv Chang under the guidance of students changed the chain email sharing share Telegraph (station and in forums is required), users with explosive growth. Because behind the company's strategy to give up contraction, another said.
I used to work with when you say when you doubt yourself boldly copying someone else's experience, used for our use. That would be more easily.
Copy the file email when you send it, plagiarism is moving forward rapidly, but overlook one thing: to copy others ', to copy somebody else doing good, than current products of the place, so that they will have to copy the necessary.
But you send it in China do not QQ file transfer more convenient, then how is it possible to copy a good result!
Thunder wallpapers
Countless people have said on the Internet product from the user's needs, and to solve the user's problem, to create value for the customer.
Thunder wallpaper launch is three points above are not detached "three noes."
I led this project is, the starting point is ridiculous. Download Xunlei client team was doing at that time was already in "do what to do are the same" dilemma, so I would like a user's client product team taking the time to do it, in case there is surprise.
It seems that this "gave the team something to do" starting point, were doomed to fail.
Because it is taking the time to do the project, there will be no formal team prepared, I the Thunderbolt's little face to pull a few easily persuaded students to help. Project release cycle, promotion plan, no way to guarantee that all the quality. Later, as a result of that there is no guarantee, wallpapers of products but I repeatedly talk to ask for help.
Then I just graduated a year chatting with him found that he was in the process of with top PM potential talents, in development and design under very limited circumstances, to really let my admiration.
Unfortunately has not been able to provide him with enough resources, then have a better development, also be a relief.
Wallpaper in this case dragged without sufficient ammunition, project cycle is too long, no regulars protection people demoralized.
On the Internet, project development time, the longer the more low morale, the likelihood of success. No one wants to be stuck in a task of no end in sight. Trapped wallpaper people achievements of this project, is a blunt knife murder.
Finally one day I decided to quit, don't be a hero, kill wallpaper.
If you are already not worth wasting a lot of time on things, then hurry. Missed time will never get it back, and worse than continuing to waste time.
This I know, but when I come when I did a mental construction of a long.
Wallpaper is an example of the failure of to solve an old problem, introduced a new issue of the case. Then make a new project, I ask myself, it's going to be another "wallpaper project"?
Above these four things are I, as "the main culprit" of crimes committed. Because my friend has a lot of Thunder's students, I try to objectively describe the feeling at that time, if I have offended you, please forgive me, primary responsibility is on me.
