In his post, Adam talks about his reading journey, and that he wants to get some regular reading done.
As I have followed business leaders and entrepreneurs, a common theme has come up. They all read regularly, and a lot!Fast(er) reading
As Adam states in his post that he's a slow reader, I'm also not one of the fastest readers myself. I did start out with some (fast) reading techniques on lifehacking.nl earlier this year which already helped me in reading a little bit faster. The site is in Dutch, but you can probably find similar sources in English or translate it.
I'm currently at the stage of reading at 90 bpm and 2-3 stops per line. At that speed I can notice I stop the subvocalization (inner speech), which is a big part of slowing readers down. Sometimes it's hard to keep following the rules of speed reading, I'm having a hard time with regression (looking back in the text). So this reading goal is a good place to keep practicing those things and progressing even further.
For my goal to be SMART, I'm going to start out small and set my goal to 25 pages a day for 100 days, that will take me to October 11th, because I already started last Monday.

One of the packages in SSIS was taking ages to process so I used sp_WhoIsActive by Adam Machanic (b | t) and came to the conclusion the process had a wait type of PREEMPTIVE_OS_WAITFORSINGLEOBJECT, which can be found in sys.dm_os_wait_stats.
Jonathan Kehayias (b | t) mentions on MSDN:
For a thorough understanding of (Non-)Preemptive waits in SQL Server, Pinal Dave (b | t) has written an excellent blog post here. A little excerpt:
PREEMPTIVE: Simply put, this wait means non-cooperative. While SQL Server is executing a task, the OS interrupts it. This leads to SQL Server to involuntarily give up the execution for other higher priority tasks. This is not good for SQL Server as it is a particular external process which makes SQL Server to yield. This kind of wait can reduce the performance drastically and needs to be investigated properly.You see the word drastically there? That's kinda what happened :)
The buffer manager has allocated # bytes even though the memory pressure has been detected and repeated attempts to swap buffers have failed.
The buffer manager failed a memory allocation call for 65536 bytes, but was unable to swap out any buffers to relieve memory pressure. # buffers were considered and # were locked. Either not enough memory is available to the pipeline because not enough are installed, other processes were using it, or too many buffers are locked.
The maximum server memory can be set by editing the Server Properties (in SSMS):
or by using plain T-SQL. The beneath example sets the maximum memory to 4 GB:
sp_configure 'show advanced options', 1; GO RECONFIGURE; GO sp_configure 'max server memory', 4096; GO RECONFIGURE; GO

As you may have noticed, I'm starting tomorrow, June 1st, at Pulse (t | web) in Venlo, that's near the border with Germany. I had a couple of days off so my last day at ADA was last week. I already said goodbye to my colleagues, had some time to clear my head and spend some extra time with the kids, which is always great!
I have to say I enjoyed my time at ADA (t | web). I really liked my colleagues and the laughs I had with them. That doesn't mean I was always doing what I really wanted or liked most. I understand that the best jobs and the nicest customers aren't always available (for me). But in the long run you have to have fun and find a challenge in what you do!
So I decided to take a leap of faith and that's how I found Pulse, or actually they found me (ok, actually a recruiter found me). I'll be fulfilling an MS BI Consultant role there.
Pulse is an MS Gold Partner with Dynamics AX (ERP) on which they also built a BI framework. And now with the content packs of PowerBI the availability and quality of the solutions will only get better I believe.
Hopefully I will get (yes I know, I have to make time) a bit more time to blog and I'll let you know how my choice turns out!
