Fabulous Adventures In Coding : The Stack Is An Implementation Detail, Part One - 0 views

  • Almost every article I see that describes the difference between value types and reference types explains in (frequently incorrect) detail about what “the stack” is and how the major difference between value types and reference types is that value types go on the stack.
  • I find this characterization of a value type based on its implementation details rather than its observable characteristics to be both confusing and unfortunate. Surely the most relevant fact about value types is not the implementation detail of how they are allocated, but rather the by-design semantic meaning of “value type”, namely that they are always copied “by value”.
  • Of course, the simplistic statement I described is not even true. As the MSDN documentation correctly notes, value types are allocated on the stack sometimes. For example, the memory for an integer field in a class type is part of the class instance’s memory, which is allocated on the heap.

  • As long as the implementation maintains the semantics guaranteed by the specification, it can choose any strategy it likes for generating efficient code
  • That Windows typically does so, and that this one-meg array is an efficient place to store small amounts of short-lived data is great, but it’s not a requirement that an operating system provide such a structure, or that the jitter use it. The jitter could choose to put every local “on the heap” and live with the performance cost of doing so, as long as the value type semantics were maintained
  • I would only be making that choice if profiling data showed that there was a large, real-world-customer-impacting performance problem directly mitigated by using value types. Absent such data, I’d always make the choice of value type vs reference type based on whether the type is semantically representing a value or semantically a reference to something.

Jonathan Schwartz's Blog: Sun's Network Innovations (3 of 4) - 0 views

  • this datacenter systems market is more than $150b annually. And in this datacenter market we build exceptional systems
  • storage, from our new flash based platforms to eco-efficient tape and archive solutions.
  • more than just naked components, they're engineered with remote management and monitoring, component redundancy, integrated virtualization, and on board storage and networking. That's why our margins are higher than the industry's
  • ...7 more annotations...
  • we now build our entire line of storage systems from general purpose server parts, including Solaris and ZFS, our open source file system.
    • David Corking
       
      So, can anyone build a Sun storage device, or are Sun's "general purpose server parts" better (with better management and redundancy ...) ?
  • using a general purpose OS allows us to easily embrace specialized components (from flash memory to GPU's)
  • why am I paying you a million dollars?" I responded, "You can absolutely run it for free. You just can't call me on Christmas day, you'll be on your own." He gave me the PO.

      Schwartz gives the strong impression of an IT company _without_ its hand in your pocket. It is a similar attitude and reputation, though with proprietary software, rather than services (for free software), that seems to have made Microsoft so wealthy in the late eighties and nineties.
  • Solaris OEM agreements with IBM, Dell, Intel, Fujitsu and HP are so important to our end customers - they know they'll never be locked in.
  • These open source platforms generate, alongside the services attached to them, over a billion dollars a year, making Sun by far and away the world's largest open source software company.
    • David Corking
       
      Hundreds of millions of dollars a year from open source Java alone!
  • Fighting free and open software, like fighting free news or free search, is like fighting gravity - and btw, gravity gets a lot stronger during economic downturns.

  • There is a robust, well-designed open source PBX Server called SipX that is primarily backed by Nortel (due to their acquisition of the creators, Pingtel).

Jonathan Schwartz's Blog: Sun's Cloud (4 of 4) - 0 views

  • our sales and partner force has a tenth the resources of our biggest peers.
    • David Corking
       
      Is he talking about IBM, EMC, Microsoft, Oracle, Cisco and SAP? I beat Sun has more pony tails than its peers. I would like to see those numbers.
  • inside Sun, we're just now rolling out a version of OpenOffice extended for the cloud.
    • David Corking
       
      Simple but sweet. I doubt it wil beat Google Docs for attracting collaborating groups, but it might! Corporations may want to do something similar with their private storage. How do they avoid malicious macros propagating from one cloud user to the next?
  • VB users will see a new feature later this year, offering an upload service to those wishing to archive or run multiple OS/application stacks - in Sun's Cloud.
    • David Corking
       
      VB doesn't mean "Visual Basic" any longer. This is clever leverage, I think, and one that will be supported by the open source community, because the cloud specs are open documents.

  • Clouds are just as interesting to students and startups as they are to Fortune 500 customers.
    • David Corking
       
      perhaps much more interesting?

  • By having a domain that isn't just a subdomain (ie, x.facebook.com) like fbcdn.net, each request isn't burdened with the additional cookies and thus minimizes the bandwidth required on the request

    So what is the best way to set up NoScript to avoid XSS attacks from Facebook users?
