Wine testing.browser testing.what's the difference? In the earlier days of web development, executing cross-browser testing used to be very easy. There used to be only a few limited browsers, each browser had limited versions in usage, and most importantly, there were not so many different mobile screen sizes to worry about. But time has turned upside-down, now there are multiple devices to check on, there are many different browsers available on the market that are used by a considerable number

My good friend Aaron Bertrand inspired me to write this article. He reminded me of how sometimes we take things for granted when they seem obvious to us and don't always bother checking the full story behind them. The relevance to T-SQL is that sometimes we assume that we know everything there is to know about certain T-SQL features, and don't always bother checking the documentation to see if there's more to them.

Some versions of HammerDB (e.g. 3.2) may induce imbalanced NUMA utilization with SQL Server. This can easily be observed with Resource monitor. When NUMA imbalance occurs one of the NUMA nodes will show much larger utilization than the other. E.g. Imbalanced NUMA usage by SQL Server. The cause and fix is well documented on this blog. In short HammerDB issues a short lived connection, for every persistent connection.

When was the last time you were in the flow while working through some code? Reading code or doing code reviews is an activity that we do often, yet we don’t often get into the zone doing it. Too many times, we have to slow down, check that last line again or try to figure out the structure of the code. Even though we all follow the same principles for clean code, there is always that gut feeling that tells you that one style is better than the other.
