## Nim - the first high performance language with full support for hot codereloading at runtime
by Viktor Kirilov
## Me, myself and I
• my name is Viktor Kirilov - from Bulgaria
• creator of doctest int
high: int
iterator items(range: CustomRange): int =
var i = range.low
while i <= range.high:
yield i
inc i
iterator pairs(range: CustomRange): tuple[a: int, b: char] =
for i in range: # uses uses CustomRange.items
yield (i, char(i + ord('a'))
for i, c in CustomRange(low: 1, high: 3):
echo c
# prints: b, c, d

## Symbolic Calculus for High-Performance Computing from Scratch using C++23
Vincent Reverdy
Laboratoire What this talk is not about
■ Complicated maths (you are smart people, you can do it yourself)
☑ High-performance computing (you all know about it + see the 2019 talk for that)
Benchmarks, assembly, concepts
■ Symbolic calculus (derivatives, integrals)
☑ Full blown custom rule-based rewriting
## High-performance
■ Since formulas have the entire information on the mathematical AST, it's possible

MYBATIS Dynamic SQLhttp://www.tutorialspoint.com/mybatis/mybatis_dynamic_sql.htm Copyright $ © $ tutorialspoint.com Dynamic SQL is a very powerful feature of MyBatis. It enables programmers to build queries based on to write the query using the dynamic SQL. MyBatis uses a powerful Dynamic SQL language that can be used within any mapped SQL statement. Following are the OGNL based Dynamic SQL expressions provided by when, otherwise • trim where, set • foreach ## The if Statement The most common thing to do in dynamic SQL is conditionally include a part of a where clause.
