I have been involved in a constant struggle with the core IT group over how to best run the operations. They are a traditional, internal facing IT shop. They have stumbled through a private cloud initiative that is only about 30% realized. I have had to drag them kicking and screaming into the world of automated provisioning, IaaS, application performance monitoring, and all of the other IT "must haves" that a reasonable person would expect from a company of our size. All the while, I have never had full access to the infrastructure. I do not have access to the storage. I do not have access to the virtualization layer. I do not have Domain Admin rights. I cannot see the network.
The entire organization has been ham strung by an "enterprise architect" who relies on consultants to get the job done, but does not have the capability to properly scope the projects. This has resulted in failure after failure and a broken trail of partially implemented projects. (VMware without SRM enabled. EMC storage hardware without automated tiering enabled. Numerous proof of concept systems that never make it into production because they were not scoped properly.)
After 5 years of succeeding in the face of all of these challenges, the organization has offered me the Enterprise Architect position. However they do not think that the position should have full access to the environment. It is an "architecture" position and not a "sysadmin" position is how they explained it to me. That seems insane. It is like asking someone to draw a map, without being able to actually visit the place that needs to be mapped.
For those of you in the community who have similar positions, what is your experience? Do you have unfettered access to the environment? Are purely architectural / advisory roles the norm at this level?
"My mental model of CPUs is stuck in the 1980s: basically boxes that do arithmetic, logic, bit twiddling and shifting, and loading and storing things in memory. I'm vaguely aware of various newer developments like vector instructions (SIMD) and the idea that newer CPUs have support for virtualization (though I have no idea what that means in practice). What cool developments have I been missing? "
An article by Dan Luu answers this question and provides a good overview of various cool tricks modern CPUs can perform. The slightly older presentation Compiler++ by Jim Radigan also gives some insight on how C++ translates to modern instruction sets.
It's tough to get more than a general sense of how much money gets contributed to which foundations by which companies – however, the numbers aren't large by the standards of the big contributors. The average annual revenue for the open-source organizations considered in the analysis was $4.36 million, and that number was skewed by the $27 million taken in by the Wikimedia Foundation (whose interests range far beyond OSS development) and the $17 million posted by Linux Foundation.
