What is software engineering?
Software Engineering (SE) is the branch of computer
science that deals with the design, development,
testing, and maintenance of software.

Things to understand
Every software has to evolve
🐵
More complexity → less quality

Text summarisation
Text:
French authorities have placed seven more
departments covering major cities such as Lille,
Strasbourg and Dijon on high alert as increases
in Covid-19 infections accelerate, the
government said Sunday. Of France's 101
mainland and overseas departments, 28 are now
considered "red zones" where authorities will be
able to impose exceptional measures to slow
the number of new coronavirus cases. The move
comes as France reported a record of nearly
9,000 daily cases on Friday, and a further 8,550
cases in the past 24 hours on Saturday, when the
nationwide test positivity rate increased to 4.7
percent…
Summary:
France puts more departments
on Covid high alert
