Full day PreCon Practical Performance Analysis in Melbourne at Asia & Australia Tour 2018
As it has almost become a habit by now for me, I will be touring Asia this summer. This year not only Asia, but for the first time also Australia. (There, however, is winter, which sometimes leads to funny confusion in agreements until you get used to this.) 1st stop: Singapore – Azure SQL Database […]
