Setting up Windows 10 IoT Core on Raspberry Pi from a VM

0 comments

Following Build last week, I wanted to try running Universal Apps on a Raspberry Pi 2, but the setup instructions mention having to provision the SD card from a physical Windows 10 machine. It must be physical because the OS needs raw access to the SD card, and only Windows 10 is able to flash […]

Taming Transaction Logzilla

6 comments

A transaction log, if sized sensibly, is like a ring buffer. It will stay the same size however much data it holds, up to a point. It is when something goes wrong that the log can turn into a disk-space-devouring monster, and my heart sinks whenever I stumble across a forum or Q&A post advocating […]

Looking for outdated statistics

0 comments

Outdated statistics are a major cause of bad query plans in SQL Server’s. Even when we have ‘Auto Update Statistics’ on, this doesn’t solve the problem, because the formula for the number of modifications that triggers the ‘Auto Update Statistics’ is 20% + 500.

Whose fault is it if a database is hacked and its contents appear on a hacker’s site? Sure, the hacker is the criminal, but could you, the DBA, have prevented the crime happening to your servers?  In the end, the odium that follows a data breach descends on the company who is storing the data, […]

How to query Included columns and more index metadata

0 comments

The Database Neighbours From Hell

5 comments

In the Windows environment, there seems little safer for application design than a rather staid single-tiered architecture making ODBC/JDBC calls to the RDBMS. I can say this with years of experience in developing applications ranging from the dull but worthy, to the esoteric. However there is an interesting long-term cost to taking the easy route […]
