NPersist focuses on delivering the productivity promise of O/RM, fulfilling performance demands only to the degree that they don’t come into conflict with productivity concerns.
Primary attention is directed toward maintenance of object-graph consistency and features that help developers avoid common pitfalls of O/RM, such as forgetting to explicitly inform the framework which objects have been modified and which objects require lazy loading.
In addition to supporting persistence to relational databases, NPersist also lets you map your objects to:
• XML documents (Object/Document Mapping)
• Other object graphs (Object/Object Mapping), which can be useful, for example, when mapping a presentation model to a domain model
• Web services (Object/Service Mapping), which can be useful when developing rich client applications that don’t have direct access to the database
Together, all these features allow a high level of productivity when using the NPersist framework and make it applicable to a large set of scenarios and development styles.
I have often described my work in the 802.11 working group as the
best job I ever had, even though it was a part-time volunteer position
that came without pay. As a regular attendee, I had a ringside seat for
much of the 802.11n standardization effort, culminating in a vote in the
summer of 2009 to approve the task groups final draft. Procedurally, it
was a vote like many others I attended, but there was an electricity in
the room. After years of exertions to meet the yearning of users for more
speed, we were delivering a long-awaited standard. Even though the outcome
of that final vote was not in doubt, I went to that meeting in part so
that I could say I was there. As it turns out, I do have an interesting
story to tell because the final vote was 53 in favor and one against
proceeding, and many people want to understand why there was one no
When I started with wireless LANs, it would have been unthinkable to
use them as the primary method of connecting to a network. By delivering
802.11n, some of the smartest people I know have made it unthinkable not
to do so. For most practical purposes, wireless networks are now on par
with Ethernet. While wireless networks may seem like the obvious choice,
few have a firsthand appreciation for technical and intellectual firepower
trained within the 802.11 working group that makes it possible.
The high school standards specify the mathematics that all students should study in order to be college and career ready. Additional mathematics that students should learn in order to take advanced courses such as calculus, advanced statistics, or discrete mathematics is indicated by (+), as in this example:
(+) Represent complex numbers on the complex plane in rectangular and polar form (including real and imaginary numbers).
All standards without a (+) symbol should be in the common mathematics curriculum for all college and career ready students. Standards with a (+) symbol may also appear in courses intended for all students. The high school standards are listed in conceptual categories:
The best website in the world wont do you much good if its sitting out there all by its lonesome self. For your site to flourish, you need to find the best way to attract visitorsand keep them flocking back for more. In this Mini Missing Manual, youll learn some valuable tricks for promoting your site. Youll also see how search engines work, how to make sure they regularly index your site, and how to work your way up the rankings of search results. Lastly, youll learn to gauge the success of your site with visitor tracking, and youll use a powerful free service called Google Analytics to learn some of your visitors deepest secrets (like where they live, what browser they use, and which of your web pages they find absolutely unbearable). Before you know it, youll be more popular than chocolate ice cream.
Your Website Promotion Plan
Before you plunge into the world of website promotion, you need a plan. So grab a pencil and plenty of paper, and get ready to jot down your ideas for global website domination (fiendish cackling optional).
The light used for food and tabletop shots is often very similar to daylight, and often it is modulated to give it a soft look. The simplest way to produce soft light is to shine it through a diffuser or bounce it off a reflector. If you deliberately let some light from the flash spill over to light the subject directly, it can help give the scene a sparkling, sunny look. The downside is that the contrast increases and is more difficult to control, which often results in overexposed highlights. In situations like this, shoot in RAW format if you can. It will give you the most leeway for adjusting proportions of the shadows and highlights later.
In this section I discuss three different setups to obtain various looks to the images.
