"You must have never seen the bug experience that stunned you!"

A word of positive energy every day

A person is like a vine, his existence is supported by other things, and he gains strength from embracing others by embracing others.

"Spiritual event! A new bug has been found in the program, but it is running normally!", "Who would believe that my computer crashed because the resonance amplitude of the hard disk was too large when I put it on the Qinghai-Tibet Plateau—"...There are bugs everywhere in life
, Which one stunned you the most, and you will never forget it for a long time? Come and share it today!

In the programmer's world, a bug is like an annoying ghost that may appear at any time, but it is difficult to eliminate. Sometimes you may find that a seemingly impeccable program has a weird bug, which makes you feel very surprised and helpless. But what can stop programmers' enthusiasm for exploration and creation? Today, let us share some of the most bizarre and unbelievable bug events!

encountered bugs

In program development, everyone will encounter bugs, big or small. Beginners generally encounter relatively simple problems, such as spelling mistakes, missing letters, not distinguishing between upper and lower case, switching between Chinese and English punctuation marks, etc. of. Of course, older programmers make occasional mistakes, but more often they are other mistakes.

The bugs I encountered in the development include the establishment of the development environment, the exact same computer, and the same configuration, sometimes it just fails. The most bizarre one is that I tried all kinds of solutions that day, restarted the computer, thought about all possible solutions, and prepared to ask the leader for help the next day, but turned on the computer the next day and it was fine. Let me talk about the bugs encountered by the programmers around me.

There are countless weird bugs encountered by programmers. Below I will give a few examples to illustrate.

1. "Crash when inputting Chinese characters": When a programmer was writing code, he found that the program always crashed when inputting Chinese characters. He conducted many investigations and attempts, and finally found that the cause of the crash was that he used English single quotation marks instead of Chinese single quotation marks in his code.

2. "Bugs caused by music recognition": When a programmer was developing a speech recognition software, he found that as long as there was music playing next to the computer, the program would have recognition errors. After many experiments, he found that this was caused by the frequency conflict between the speech recognition engine and the music playback engine.

3. "Magical Bug Caused by Time Difference": There is a programmer who is troubled by a strange problem. When he is testing the code, the problem always does not appear, but when he puts it in the formal environment, the problem will appear. Finally, he finally found out the problem. It turned out that this magical bug was caused by the inconsistency between the time of the test and the official environment.

These examples show that it is very common for programmers to encounter bugs when writing code. But as long as you carefully and patiently conduct troubleshooting and analysis, you can eventually find out where the problems are and fix them.

The discovery process of bizarre bugs

In general, bugs may be discovered from multiple sources. Testers may find some abnormalities or errors during testing, and give feedback to developers in time. Alternatively, developers can identify potential issues through code reviews or self-tests. In addition, users may also report some abnormal situations or errors. In general, the discovery of bugs can come from various aspects, requiring the joint efforts of developers, testers and users to ensure the quality of software.

The discovery process of bizarre bugs usually requires programmers to have certain analytical skills and an open mind. The following is the discovery process of the bizarre bug:

1. Confirm the problem: First of all, the programmer needs to make sure that there is a bug, which may be found in user feedback, testing or own use. Programmers need to record the specific manifestations and circumstances of the bug.

2. Analyzing the cause: Analyzing the cause of the bug requires the programmer to have certain analytical skills and an open way of thinking, thinking about the problem from all possible angles. Programmers need to find the root cause of the problem through data analysis, code review, collaborative debugging, etc., and eliminate factors that may not be the cause.

3. Verify the solution: After analysis, the programmer needs to propose a solution and verify it. This step usually requires programmers to write test code, simulate the environment, and verify the feasibility of the solution.

4. Implementation and testing: If the solution works, the programmer needs to implement it into the code and perform additional testing to ensure that the bug is fully resolved, not glossed over.

The discovery process of bizarre bugs requires programmers to have certain analytical skills and creativity, to think about problems from various angles, and to accumulate experience and inspiration in practice.

Subsequent bug handling

Not all bugs can be handled by programmers, but we can avoid some that may arise. However, try to avoid it as much as possible.

The specific methods and steps to deal with strange bugs depend on the specific situation. The following are some common ways to deal with them:

1. Confirm whether the bug really exists: First, you need to confirm whether the bug really exists, that is, by reproducing the problem and checking the code, logs, test reports and other information to determine whether the bug is a real problem, or just a false positive or misjudgment. Try to reproduce the bug and confirm the conditions and circumstances under which it occurs.

2. Priority assessment: If it is determined that the bug is a real problem, then it is necessary to perform a priority assessment on the bug, and determine the priority of processing according to its impact and urgency, as well as the time when the bug needs to be resolved.

3. Analyze the cause of the bug: After the bug is identified, it is necessary to analyze and troubleshoot its cause. It may be necessary to troubleshoot the code, configuration, environment, and other aspects to determine the problem.

4. Submit a repair plan: After analyzing the cause of the bug, you need to formulate a corresponding repair plan, modify the code or perform other operations to solve the problem.

5. Submit test cases: If the bug is discovered through testing, then it may be necessary to write a corresponding test case to verify that the bug has been resolved.

6. Acceptance and Confirmation: Verify and confirm the repaired bugs to ensure that the problems are completely resolved.

7. Reflection and summary: Reflect and summarize the process of dealing with bizarre bugs, and explore the crux of the problem, so as to avoid similar problems in future development work.

Bizarre bugs are often caused by some special circumstances or operation methods, and special attention is required. The reason may be related to system architecture, code implementation, user operation, etc., and in-depth analysis is required to find a solution.

postscript

As a software developer, you are often faced with all kinds of strange bugs, some of which are really jaw-dropping, and it is hard to imagine how they appeared. I remember one time, the application we developed would crash for a certain period of time, but we tested repeatedly and found no problem. Finally, we found a user. Through communication with him, we found that he would perform a very special operation during this time period every day, and this operation was very complicated, and it seemed to have nothing to do with our program. But we decided to try to simulate this user's actions, and finally found a hidden bug, and it was not like any bug we had encountered before. This experience made me realize that sometimes it is really necessary to communicate more with users to understand their specific usage methods and habits in order to find those seemingly unrelated bugs.

Another time, we had a very bizarre bug in our app that would appear on a certain date and only trigger when the user took a certain action on that date. It took us a long time to find the root of the problem. It turned out that we missed a special case in the date processing process, which caused the program to malfunction. This experience made me deeply realize that no details should be missed, and various situations need to be fully considered to avoid such strange bugs.

In general, the emergence of bugs is inevitable, but we need to stay vigilant, communicate more with users, and pay attention to details in order to better discover and solve these bugs and make our applications more perfect.
