2. Haskell

Michael Snoyman O'Reilly Media ePub

Haskell is a powerful, fast, type-safe, functional programming language. This book takes as an assumption that you are already familiar with most of the basics of Haskell. There are two wonderful books for learning Haskell, both of which are available for reading online:

Learn You a Haskell for Great Good! by Miran Lipovača (No Starch Press)

Real World Haskell by Bryan O’Sullivan, John Goerzen, and Donald Bruce Stewart (O’Reilly)

Additionally, there are a number of great articles on School of Haskell.

In order to use Yesod, you’re going to have to know at least the basics of Haskell. Additionally, Yesod uses some features of Haskell that aren’t covered in most introductory texts. While this book assumes the reader has a basic familiarity with Haskell, this chapter is intended to fill in the gaps.

If you are already fluent in Haskell, feel free to completely skip this chapter. Also, if you would prefer to start off by getting your feet wet with Yesod, you can always come back to this chapter later as a reference.

The Object Model Viewer

Methods

In a way, properties are static, in the sense that they describe a state. Methods, on the other hand, are dynamic in that they “do something.” For instance, many objects have a method called .add (), which, as the name suggests, adds an object; these include document, page, textframe, and index. For instance, app.documents.add () creates a new document and app.activeDocument.pages.add () adds a page at the end of the current document. Methods are listed separately in the object-model viewer, and they can be easily spotted as they have parentheses following them, with or without parameters. To contrast properties and methods, here is an example of each, both to do with capitalization: app.selection[0].paragraphs.item (0).capitalization = Capitalization.smallCaps; app.selection[0].paragraphs.item (0).changecase (ChangecaseMode.titlecase);

In the first line, capitalization is a property that can be inspected or set. To read a property, you use the part of the line up to the equal sign. ESTK tells you what the property is; we’ve seen several examples of that earlier. To set a property, as shown here, use the appropriate parameter (or enumeration). Here, too, the problem is how to find out what enumerations are possible; again, the answer is that you’ll have to read through the OMV.

ELLINGHAM SUFFOLK JANUARY 1972

Below a water-mill at midnight breaking the river Waveney into white an intricate water-dance of forty-one swans and one man leaning from the mill window smokes and broods ravished and nothing understood .

LANCASHIRE NOVEMBER 1971

Inside a vertical cylinder, less than man-sized, the flash has caught rough dark metal, a rectangular slit with shadows of trees waving beyond it, and on the circular floor four letters, and four snails half drunk on glue, rasping their happy night through sandwiches of te n penceworth of stamps.

WASHINGTON SEPTEMBER 1971

The Kennedy Center for the Performing Arts, the crowded image of the dedication.

The ranks and braid, the sapphires and white gloves.

The tiers, the tears, the cheers, the chandeliers.

The brass band and the rock band and the dancers, the ended Mass, the stage in flowers, the curtain falling on pressmen hugging weeping Bernstein.

A spotlight on Rose Kennedy mother of the dead standing at eighty facing like a sphinx beyond the clapping hands, the Kennedys all round like swaying ears of harvest. Stars of crests of diamonds, medals, rings four-deep on fingers flashing programmes flash and twinkle .

2. Save Money with Skype

Andrew Sheppard O'Reilly Media ePub

For some people, Skype might be a sufficiently interesting application of VoIP technology to justify playing with it. For most people, however, the motivation for bringing Skype into their life will be based on simple economics. Skype has the potential to save you money; in fact, quite a lot of money!

In this chapter, I will help you get a handle on whether Skype will save you money and, specifically, how much money. Given the wide range of telephone services that Skype can potentially replace, or complement, I cannot cover every scenario. But this chapter does provide some ways of looking at the potential savings and some tools to quantify those savings. Your goal is to estimate these savings with a sufficient margin for error so that you will feel confident enough to make a decision: switch to Skype, or stick with what you've got.

Switching to Skype is not an all-or-nothing proposition. You may choose to use Skype merely as an adjunct to your existing phone services. Alternatively, you may choose to run Skype in parallel with your existing setup for a while before switching fully to Skype. If you're bold, you may leap right in and make Skype a full-blown replacement to your existing telephone system. Whatever approach you take, when figuring savings your focus will necessarily be on the long-term savings of your telephone system as it will look sometime in the future. For this reason, and as an aid for comparisons, I will express savings on an annual basis.

Chapter Twenty-Four Blown Apart

Carol A. Grund Pauline Books and Media ePub

It had all started with some swelling in her neck, Danny explained. She thought it was just an infection. But when it didn’t go away and her doctor did more tests, their family was stunned to learn that she had lymphoma, a kind of cancer that attacks white blood cells. She started treatment right away. And while Danny understood that none of this was her fault, he couldn’t help resenting the sudden changes in his life.

“I remember visiting her in the hospital,” he said. “Then I remember her being tired all the time. There were a lot of things she couldn’t do anymore. My dad tried to take care of all of us, but he had to go to work. In fact, he had to work as much as he could, in order to pay all the extra bills.”

Everyone knew his mother was sick, he said—it wasn’t like they were trying to keep it a secret or anything. At first people brought meals over, and her name was added to the prayer list at St. Brigid’s. His grandparents came to help out sometimes, and so did the aunts who lived in Indiana. That first summer, they had even taken Danny back there with them. But he’d been so homesick and miserable they’d had to let him go home.
