Top 5 Worst Computer Blunders In History

The computer has become an indispensable part of our lives. We use it for work, play, and everything in between. But even the most powerful computers are susceptible to blunders that have serious consequences – millions of dollars in loss, embarrassment, reputation damage and even deaths.

It is important for us to look at these computer blunders as an important lesson that software testing is an essential part of the software build.

Below here are some of the worst computer blunders in history:

1. The Y2K Bug

The Y2K bug, also called the Year 2000 bug or Millennium Bug, was a computer glitch feared to cause widespread problems when the calendar rolled over to the year 2000. The problem was that many computer systems stored the year as two digits, such as 99. When the year changed to 2000, these systems would interpret the year as 00, which could have caused them to malfunction. Fortunately, the Y2K bug was averted thanks to thousands of computer programmers working around the clock to fix the problem.

2. The Pentium FDIV Bug

The Pentium FDIV bug was a floating-point division error that affected some Pentium processors. The bug caused the processor to return incorrect results for certain division calculations. The bug was discovered in 1994 and was quickly fixed by Intel. However, the bug tarnished Intel’s reputation and led to a class-action lawsuit.

3. The Therac-25 Accidents

The Therac-25 was a radiation therapy machine that was used to treat cancer patients. However, the machine was plagued by software problems that caused it to deliver overdoses of radiation to patients. The accidents caused the deaths of six patients and the injuries of several others. The problems with the Therac-25 were caused by a combination of factors, including software bugs, hardware failures, and human error.

4. The Ariane 5 Disaster

The Ariane 5 was a European space rocket that was launched in 1996. However, the rocket exploded shortly after liftoff due to a software error. The error was caused by a mismatch between the units of measurement used in the rocket’s software and the units of measurement used in the ground control system. The Ariane 5 disaster was a major setback for the European space program.

5. The Sony BMG Rootkit Scandal

In 2005, Sony BMG was caught inserting a rootkit into some of its CDs. A rootkit is a type of malware that gives an attacker full control over a computer. The rootkit was installed on computers when users played CDs that were infected with the malware. The rootkit scandal caused a major backlash against Sony BMG and led to a class-action lawsuit.

Conclusion

These are just a few of the worst computer blunders in history. While these blunders caused many problems, they also served as an important reminder of the importance of testing and quality control in software development.
