  •  
    Viagra tablet buy online in pakistan is a standout amongst another sexual upgrade supplement. Viagra Tablets is so well known on the planet and now accessible in Pakistan. With a rushed way of life combined with the absence of good dietary patterns, the strength of an individual today is a long way from immaculate. Cialis Tablets in Pakistan One of the most disturbing consequences of such a way of life is the absence of sexual vitality in men. Viagra-Tablets Women surveys are certain about Viagra's capacity to make fulfillment and quietness inside a relationship where dissatisfaction and contact had once been the standard. Viagra-Tablets one of the best early audits demonstrated a progression of couples joyfully moving together after Viagra evidently relieved the loss of beat in their relationship.

Interview with Designer: Marius Roosendaal - 0 views

  •  
    I do a lot of things, but I'm guessing you want to know more about my professional life. I mostly keep myself busy designing interactive and digital stuff, and I've been doing that for about 6 years. I also like to look over other people's shoulders and tell them they need to align something or make something or other red. Aside from that I like to do explorations with abstract geometry, patterns and typography. Some call it art, or at least want to put it on their walls or albums covers. It' s a lot of fun, and it gives some variety to my usual work of designing menus and layouts.

How to Combine Typefaces - 0 views

  •  
    I recently finished reading Tim Brown's new book "Combining Typefaces." It's 63 pages. You can buy it for less than $5 on FiveSimpleSteps, as a pdf or epub. Combining Typefaces is a dense book. It goes through a lot of concepts very quickly, but I'm a fan of that. The book may be primarily about combining types, but I think it serves as a great introduction to typography as a whole. It goes over anatomy and general terminology, but the book primarily approaches typography as a form of artistic communication, instead of just a set of guidelines and formulas. This is important, because that means it accepts subjectivity. There is no one answer to type, no winning approach; all we have are the techniques and patterns observed and used by of artists and designers throughout centuries. It challenges you to think about typography in your own way: how will you create what you want to communicate? What will you use? How will you use it?

Policy Injection App Block - Behind the Scenes - 0 views

  • We use an interception mechanism to get in the way of calls going to that member, collect a list of policies that apply using a matching rules mechanism, run the chain of handlers specified by those policies in a chain of responsibility and at the other end dispatch the call to the target. Once the target is done - successfully or with exceptions - the stack unwinds, returning through each handler and finally back to the caller.

    Very good read (particularly their evaluation of weaving methods).

    Although as a result their "Policy Injection" application block isn't as powerful as most of the straight-up AOP toolkits out there, it does have a *huge* upside: not only is the code produced by this supportable by Microsoft Product Support, it's now officially part of the Patterns and Practices recommendations!

    The down side is that the only injectable objects are ones created through a "Factory" method (you can't just use the *new* constructor) this brings some performance hits ... but then, you get the ability to separate concerns and apply policies and even business rules after the fact!

Joe Duffy's Weblog - OnBeingStateful - 0 views

  • The biggest question left unanswered in my mind is the role state will play in software of the future.
  • The biggest question left unanswered in my mind is the role state will play in software of the future. That seems like an absurd statement, or a naïve one at the very least.  State is everywhere: The values held in memory. Data locally on disk. Data in-flight that is being sent over a network. Data stored in the cloud, including on a database, remote filesystem, etc. Certainly all of these kinds of state will continue to exist far into the future.  Data is king, and is one major factor that will drive the shift to parallel computing.  The question then is how will concurrent programs interact with this state, read and mutate it, and what isolation and synchronization mechanisms are necessary to do so?
  • Many programs have ample gratuitous dependencies, simply because of the habits we’ve grown accustomed to over 30 odd years of imperative programming.  Our education, mental models, books, best-of-breed algorithms, libraries, and languages all push us in this direction.  We like to scribble intermediary state into shared variables because it’s simple to do so and because it maps to our von Neumann model of how the computer works.
  • ...3 more annotations...
  • We need to get rid of these gratuitous dependencies.  Merely papering over them with a transaction—making them “safe”—doesn’t do anything to improve the natural parallelism that a program contains.  It just ensures it doesn’t crash.  Sure, that’s plenty important, but providing programming models and patterns to eliminate the gratuitous dependencies also achieves the goal of not crashing but with the added benefit of actually improving scalability too.  Transactions have worked so well in enabling automatic parallelism in databases because the basic model itself (without transactions) already implies natural isolation among queries.  Transactions break down and scalability suffers for programs that aren’t architected in this way.  We should learn from the experience of the database community in this regard
  • There will always be hidden mutation of shared state inside lower level system components.  These are often called “benevolent side-effects,” thanks to Hoare, and apply to things like lazy initialization and memorization caches.  These will be done by concurrency ninjas who understand locks.  And their effects will be isolated by convention.
  • Even with all of this support, we’d be left with an ecosystem of libraries like the .NET Framework itself which have been built atop a fundamentally mutable and imperative system.  The path forward here is less clear to me, although having the ability to retain a mutable model within pockets of guaranteed isolation certainly makes me think the libraries are salvageable.  Thankfully, the shift will likely be very gradual, and the pieces that pose substantial problems can be rewritten in place incrementally over time.  But we need the fundamental language and type system support first.
