    mondrian.rolap.queryTimeout - we set it typically to 60 seconds to cancel too long running ad-hoc queries which generate too much load on the server
    mondrian.rolap.maxQueryThreads - increase it to higher number to allow more parallel Mondrian query threads if you have many concurrent users
    mondrian.rolap.cellBatchSize - we have been experimenting with this value but typically set it to 100000 (which is now the default value for Mondrian), by changing it you can modify batch size when retrieving large set of result cells
    mondrian.native.ExpandNonNative - set to true to expand more MDX expressions to SQL
    mondrian.rolap.evaluate.MaxEvalDepth - we set it to 20 as otherwise sometimes more complex MDX calculated members were failing
    mondrian.rolap.EnableInMemoryRollup - we set it to false as we have some multi-valued dimensions which cannot be rolled up by making sum of measure values for detailed members therefore we always want rollup to be calculated using SQL
    mondrian.util.memoryMon

radare2 is a very cool set of tools that you probably don't know how to use! Let's go through a simple exploit CTF challenge to understand how to use it for exploit development.

We'll be focusing on "ropasaurus rex" which is a simple challenge from Plaid CTF After checking out the latest and greatest radare from git, let's get started!

Open up ropasaurusrex in r2 and call analyze on the binary. We can list the functions with "afl"
