What I tweeted this past week, 20151016 edition

Here is some of the interesting stuff I tweeted about this past week

Compile Big Gateway Policy changes in SQL Server 
SQL Server will automatically determine the number of concurrent queries that will be allowed in the Big Gateway depending on the Target Memory. Meaning, SQL Server will allow one query per 25GB of memory up to 80% of target.
The upper limit is only enforced by the medium gateway limit since all queries in big gateway would have first passed through medium gateway. For example, on a system that has 24 physical/48 logical cores and 64GB RAM, the new behavior allows for two large 25GB query compilations up to 48 concurrent compilations (as allowed by the medium gateway) if queries do not need 25GB for compilation. This is a dramatic improvement in number of large compiles compared to earlier versions.

Cloud Computing Finally Gets Some Startups
For years, getting into the business of renting out extra computing power through the cloud has been a bit like getting into the business of nuclear power

That formula is changing as cloud startups such as DigitalOcean and Backblaze begin to compete for customers with the likes of, Microsoft, and Google. The startups have managed to underbid the giants in certain markets by keeping expenses relatively low, either by writing their own versions of the software needed to run a cloud or by handcrafting the hardware needed to house one. “All the tools we’re using really pay dividends,” says DigitalOcean Chief Executive Officer Ben Uretsky. “I think that gives us a leg up.”

Computer science is now the top major for women at Stanford University
Computer science has for the first time become the most popular major for female students at Stanford University, a hopeful sign for those trying to build up the thin ranks of women in the technology field.
Based on preliminary declarations by upper-class students, about 214 women are majoring in computer science, accounting for about 30 percent of majors in that department, the California-based university told Reuters on Friday.
Human biology, which had been the most popular major for women, slipped to second place with 208.
If more women majored in technological fields like computer science, advocates say, that could help alleviate the dearth of women in engineering and related professions, where many practitioners draw on computer science backgrounds.

Finished:  The Devil in the White City: Murder, Magic, and Madness at the Fair That Changed America
This is a book written by Erik Larson about the Chicago World Fair and a serial killer who was active at the same time the fair was happening.

Execution Comparison Tool released with latest SSMS
With the recent release of CTP 2.4, some of you might have noticed something new shipped with SSMS – a Plan Comparison option. The purpose is to provide side-by-side comparison of two different showplans, for easier identification of similarities and changes, that explain the different behaviors for all the reasons stated above, which may include regressions or sudden query performance changes.

The #MH17 investigation points to a revolution in open-source intelligence
A group of Internet sleuths who trawled social media and other open sources in the days after the July 17, 2014, downing and were able to establish that pro-Russian separatists had done the deed. Their remarkable forensic achievements are just the latest example of a citizen-driven open-source intelligence revolution that democratic policy makers must learn to welcome, even when it is a source of embarrassment.
