A turbine is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. It is widely applied in various industries such as power generation, aerospace, marine, oil and gas, and manufacturing. Predictive maintenance on turbines can provide significant improvement in reliability, efficiency, and safety, while reducing maintenance costs […]
If you’re new to C++, you may not know how the Boost libraries have helped prototype many of the features you now take for granted in the standard. Before C++ 11, using the Boost Libraries was a must if you wanted to use shared pointers, static assertions, or even create a thread in a portable […]
Business semantics “Just insert the data!” has a very different meaning depending on your field, and it is sometimes frustrating to get the proper behavior from your DataBase Management System (DBMS). For example, in investment banking, you may want to keep all the versions and have (partial) duplicates, whereas, in manufacturing, duplicates may be undesired. […]
This blog post has been co-authored with Marc Recht from FORRS, a Quasar integration partner What is so special about trading electricity? Electricity is special. Unlike other commodities, it is very challenging to store; for most consumers, it is entirely infeasible. As such, purchasing and storing electricity in advance of demand is not viable; hedging […]
Why does it matter Maps, dictionaries, associative containers… However you name it, maps are omnipresent, but do you know how much the implementation matters? This article will go over what we, at Quasar, learned about maps and hash tables after years of squeezing every little bit of power out of our CPUs. Before we dive […]
Once upon a time In November 2017, I was invited by Andy Pavlo to give a talk at the CMU about the internals of QuasarDB. During that talk, I briefly mentioned why we don’t use memory-mapped files and why it’s generally a mistake to do this. To be clear, I only had a strong intuition, […]
