Nicholas Nethercote marks
the 20th anniversary of the Valgrind 1.0 release.

It’s both delightful and surreal to see that Valgrind is still in
wide use today. Julian [Seward’s] original goal was to raise the
bar when it came to correctness for C and C++ programs. This has
clearly been a huge success. Memcheck has found countless bugs in
countless programs, and is a standard part of the testing setup for
many of them.
