Do you send out annual updates about your family around the holiday season? If so, MacWorld has written a good article about how to create a newsletter using Pages. Pages is Apple’s word processor which competes with Microsoft Word. It comes bundled with some Macs so you may already have a copy. If not, you can buy it as part of iWork. Or, if you have Mac OS X 10.6.6 or higher  on your Mac then you can use the App Store to buy it for about $20. I used the MacWorld article as a guide to design our holiday newsletter this year. Here’s a brief overview.

Start by opening iPhoto and identifying which photos you want to include in your newsletter. I found it easiest to put my photos into an album so I would be able to find them again easily when using Pages.

Next, I opened Pages and selected the “Informal Newsletter” template. I clicked on the Media button in Pages’ toolbar. I clicked on Photos and selected the iPhoto Album containing my selected photos. I then dragged the images on top of the placeholder images that appear in the template.

I clicked on the text box on the first page, selected all of the text and deleted it. Then I typed in our content.

We wanted to add a second page so I went to the Insert menu, selected Pages and added a “Back Page” since it has pre-defined locations for text and photos. I linked the text boxes on page 1 and page 2 so the text would automatically flow between them. I replaced the placeholder photos, of course, as well.

Finally, I realized that I needed more room to fit all of the text so I had to adjust the template’s layout some. I removed one of the photos on page one and added a new text box and linked it to the other box on page 1. I then changed the font and font size a bit to get everything to fit. Finally, I was satisfied with the layout. Pages is a pretty elegant program to use for tasks like this and the templates are really professional so it made this task easy to do.

Safari version 5 introduced a new feature named Top Sites which automatically displays your most frequently visited web sites. Top Sites displays thumbnail depictions of each web site in a grid of several rows and columns. This tech tip tells you how you can customize Top Sites.

You can permanently add a web site to Top Sites by going to the Bookmarks menu and selecting Add Bookmark. Then select Top Sites from the pop-up menu near the top of the small window that appears. Then click the Add button, as depicted below.

By default, Safari 5 displays Top Sites when you open a new window. You can manually display Top Sites by clicking the grid icon located near the upper left-corner of the Safari window. This grid icon is highlighted in the red circle in the picture below.

When the Top Sites grid is being displayed, you can click the Edit button in the lower left corner. Then, in the lower right corner you’ll see that you can switch between Small, Medium and Large. These choices will cause Top Sites to display 24, 12 or 6 thumbnails respectively.

You can also drag the thumbnails around in the grid so they appear in the order that you prefer. Additionally, you can click the Push Pin icon or the X icon located in the upper left corner of a thumbnail to permanently add or remove a web site from your top sites. When the Push Pin icon turns blue then you’ve permanently added the web site.

 When viewing Top Sites look for a star icon to appear in the upper right corner of a thumbnail. The star indicates that the web site has added content since you last visited the site.

RSS is a convenient way to stay abreast of news stories or articles added to a particular web site. Rather then needing to visit your favorite web site over and over, you can use RSS to be notified when a new story or article has been added as well as read some or all of that article. I like to read my RSS feeds in my email application, Mail.

Below are instructions on how to add an RSS feed to Apple’s Mail application.

1. Open a web browser, like Safari and go to a web site that offers an RSS feed. I’ll use Tidbits.com as my example, so go to http://www.tidbits.com

2. In the right-hand end of the address field you’ll see an RSS icon as depicted in this picture. Click on the RSS icon.

3. If the web site offers ONLY 1 feed then the address of the feed will be listed. In this case, Tidbits.com offers 3 feeds so I choose the “Full Text Feed” and then see a window like this one:

4. Copy the feed address, feed://tidbits.com/feeds/tidbits.rss by highlighting it and selecting Copy from the Edit menu.

5. Open Mail and select “Add RSS Feeds” from the File menu.

6.In the Add RSS Feeds window select “Specify the URL for a feed” and then select Paste from the Edit menu to paste the feed address (aka the URL) into the field. Use the picture below as a guide.

7. Click the Add button.

8. In a few seconds, you’ll see the Tidbits feed listed on the left-hand window of the Mail window under the “RSS section” as depicted below. The number to the right of the RSS feed’s name is an indication of the number of unread articles.

9. If you have added a number of RSS feeds, then you may want to rename them so they sort in a particular order as I’ve done by adding number prefixes.

Adding memory (RAM) to a computer is one of the most common upgrades made to a computer so many people think that this will speed up a computer. Adding memory to a computer can slightly improve its performance if the computer didn’t previously have sufficient memory installed to accommodate the applications which were simultaneously used. Let me elaborate to add some clarifying detail.

A computer’s processor (CPU) is a chip which carries out the instructions of an application. The faster the processor the faster tasks can be completed. Currently, common processor chips are the Core Duo, Core 2 Duo and Core i3, i5 and i7. These processors typically run at speeds around 2.0 to 3.0 Gigahertz (GHz). The speed of a computer’s processor is typically the largest factor in the computer’s performance. Typically, it’s not possible to either speed up or replace a processor in today’s desktop or laptop computers. Thus, people have to make other changes to try to improve a computer’s performance.

Applications, like Microsoft Word, are permanently stored on a hard drive. When one opens Microsoft Word then large parts of it are copied into memory (RAM). As one opens more and more applications one uses up all of the available memory in a computer. Eventually, the computer will start to use virtual memory. It’s beyond the scope of this article to explain virtual memory but, trust me, whcn I indicate that it’s slower then regular memory.

If one were to add more memory to a computer then the computer would need to rely on virtual memory less, when a lot of applications are open simultaneously. Consequently, the computer’s performance is improved. It’s common to need to add memory to a computer a few years after it was purchased especially if one has installed updated versions of applications like Word or the Mac operating system, Mac OS X. This is because new versions typically require more memory then their predecessors and thus utilize the computer’s memory faster and cause it to start to use virtual memory sooner.

Here are a few Wikipedia articles which could be useful if you want to dig deeper to try to understand some of the terms that I mentioned above: RAM (random access memory), CPU (central processing unit), GHz (gigahertz), virtual memory.

Did you know that Apple’s Preview lets you easily annotate PDFs, merge PDFs as well as delete and re-order pages within a PDF? Preview is a free application which comes bundled with Mac OS X. Apple has been quietly updating over the years and it has become quite capable and user-friendly. Just a few years ago one would have needed to buy the relatively expensive Adobe Acrobat Standard or Professional PDF Editor to do many of these tasks.

I should note that there are slight differences in how certain tasks are done if you’re using OS X 10.5′s version of Preview. All of these demonstrations are done using OS X 10.6′s version of Preview.

It’s also important to know that the following techniques may not work on all PDFs. It’s possible for a person who creates a PDF to lock the file in such a way as to prevent others from manipulating it. Typically, locking a PDF like this requires use of an application like Adobe’s Acrobat.

I’ve created short video tutorials on how to do the following tasks. Read the brief text description and then click the link to watch the video.

If you need more extensive editing capabilities then what is offered by Preview then you should check out the relatively affordable PDFPen.

1. Reorder pages in a PDF – Open a PDF file, click the Sidebar button to view the thumbnail icons for each page. Click on one of the thumbnails and drag the page up or down. Look for the horizontal blue line that appears indicating the new location of the page. To remove a page you can simply click on the thumbnail icon for a page to select it and the press the Delete key on your keyboard.

2. Extract pages from a PDF – Open a PDF file, click the Sidebar button to view the thumbnail icons for each page. Click on the first page you want to extract. If you want to extract additional pages then hold down the Command key and click on additional thumbnail icons. Release the Command key and then drag the thumbnail icons to the Desktop. A new PDF file will be created on the Desktop. Rename the file as desired. Open this new file by double-clicking to verify that it contains the pages that you want. You can re-order the pages by following the tip listed above.

3. Move pages between PDFs (Merge PDFs) – Open a PDF file, click the Sidebar button to view the thumbnail icons for each page. Open a second PDF and click its Sidebar button too. Position the two PDFs so you can view both file’s Sidebars at the same time. Select one or more pages from one file’s Sidebar and drag them into the other file’s Sidebar. Look for the horizontal blue line that appears in the receiving file’s Sidebar. This blue line indicates where the new page appear. You can re-order the pages by following the tip listed above. Go to the File menu and select Save to save the changes.

4. Annotate text in a PDF -  Open a PDF file, click the Annotate button to review a row of tools at the bottom of the window. Use these tools to highlight text in a variety of colors, draw a line through the text, enclose text inside a rectangle or oval, add a note in the margin of the PDF.

Did you know that Apple’s Mail application automatically builds a list of all recipients to whom you’ve sent email? I think it’s very useful to review this list a few times each year. By reviewing this list you can easily add useful email addresses to your Address Book and you can delete out-dated email addresses or addresses that contain typos.

Before we review this list, it’s important to understand how this list is used by Mail. When you are creating a new email message and you begin to type a person’s name or email address in the To: field you’re typically presented with a list of email addresses which match the letters that you’ve typed. This list of email addresses is a composite of email addresses from your Address Book as well as addresses listed in your Previous Recipients list.

If you ever made a typo in an email address and then sent the email message then this incorrect email address was likely added to your Previous Recipient list. By reviewing this list you can remove such undesirable email addresses.

To view your Previous Recipient list, open Mail, click on the Window menu and select Previous Recipient. You can search this list using the search field in the upper right corner. You can also sort this list by any of the columns listed: Name, Email, Last Used. You can also sort by the left-hand most column which is not named. This column indicates if the email address is saved in your Address Book. If it is then you’ll see an icon which resembles a rolodex card. If the address is not in your Address Book then this space will be blank. I like to sort by this column to find common recipient’s whose email addresses I want in my Address Book. I then select them and use the Add to Address Book button. If you don’t typically add people to your Address Book this can be a fast way to add a whole lot of people to your Address Book.

In order to remove an email address containing a typo, I often use the search field to locate it. Then, I’ll click on it to select it and then use the Remove From List button.

I like to sort the list by the Last Used date. I’ll then review the oldest addresses listed and if I don’t recognize them then I’ll select one or more and remove them from the list too.
