  • .net 4.0 Adoption Rate

    - by AKRamkumar
    What is the adoption rate of .net 4.0? When will it be on Windows Update? I heard that it is smaller than 3.5, does that mean if I install .net 4.0, it will decrease the space used by the framework? If I make an application in 3.5 and it runs on a computer that has 4.0, will my application get some of the optimizations that 4.0 uses?

  • html5 video secure streaming?

    - by citizenmatt
    Does html5 allow me to do secure streaming video? And by this, I mean token authentication. I want to be able to stream media only to those people who are authorised to view it. I can do this currently with Flash Media Server hosted by Akamai - they have a custom mechanism where I send them a token as part of the player connection handshake. Does html5 allow for this, and has anyone implemented this with a hosting service such as Akamai? Thanks Matt

  • Scrapy domain_name for spider

    - by Zeynel
    From the Scrapy tutorial: domain_name: identifies the Spider. It must be unique, that is, you can’t set the same domain name for different Spiders. Does this mean that domain_name must be a valid domain name, like domain_name = 'example.com' Or can I name domain_name = 'ex1' The problem is I had a spider that worked with domain name domain_name = 'whitecase.com' Now I created a new spider as an instance of CrawlSpider and named it domain_name = 'wc2' but I am getting the error "could not find spider for domain "wc2""

  • Sparxsystems Enterprise Architect and issuses/tasks tracking system?

    - by peperg
    We (developement team 4 upto 7 people) use Sparxsystems EA for requirement analysis, modeling etc. Do you know any well-working methods to use EA and some task/issue tracking system like Redmine/Mantis/Trac ? The problem is not to duplicate functionality (there are issues/tasks/changes in Redmine and EA) but to have some user friendly interface (preffered web) to manage tasks and issues. By user-friendly I mean "my tasks" page add effort / time tracking easy "add issue" by everyone (simple bug tracking system) mail notifications

    - by Jenea
    I have a asp.net mvc site that references a couple of libraries. Recently I discovered that it is necessary to migrate those dlls to .net 4 (I mean compile them for .net 4). Can I run asp.net mvc 1 on .net 4. Migration to asp.net mvc 2 is postponed because of the removal of response.WriteSubstitution(...) method.

  • Fast Remote PHP Technique To Detect Image 404

    - by Volomike
    What PHP script technique runs the fastest in detecting if a remote image does not exist before I include the image? I mean, I don't want to download all the bytes of the remote image -- just enough to detect if it exists. And while on the subject but with just a slight deviation, I'd like to download just enough bytes to determine a JPEG's width and height information. Speed is very important in my concern here on this system design I'm working on.

  • Do any JS implementations currently support (or have support on the roadmap for) fast, vectorized op

    - by agnoster
    I'd like to do a bit of matrix/vector arithmetic in JavaScript, and was wondering if any browsers or other JS implementations actually have support for vectorized operations, for instance for quickly summing the entries of two Arrays (or summing, or whatever). Even if that currently doesn't mean it compiles down to vectorized operations, at least some language support would be nice for when it does get implemented - I'd take the existence of functions or syntax to support it as a step in the right direction. (Understandably, "vectorization javascript" searches are pretty much all about graphics and SVG.)

  • is (StringComparison.)Ordinal the same as InvariantCulture for testing equality?

    - by Tim Lovell-Smith
    From what I read so far, it sounds like these StringComparison types are meant to differ in how they do sorting of strings, if so, does that mean that it does'nt matter which StringComparison you use when doing an equality comparison? string.Equals(a, b, StringComparison....) Extra credit: does it make a difference to the answer if we compare OrdinalIgnoreCase and InvariantCultureIgnoreCase? What is the answer then? Please provide supporting argument and/or references.
