Here's how to use Plex, a free tool for streaming media from a PC to a Roku set-top box. And if your PC seems to be too sluggish to play media promptly, I'll give you some tips to decide when it's time to reinstall Windows.

My tiny Roku set-top delivers everything I could possibly want to my TV: Amazon (both Prime and Instant), Netflix, Hulu, HBO, and Pandora.

Well, okay, not quite everything: The Roku can't stream my personal library of music, photos, and videos without a little help from Plex, anyway. Plex works like a charm, though it can be tricky to set up. Here's how to get started:

1. Add the Plex channel to your Roku.

2. Download and install the Plex Media Server utility for Windows. This is the software that'll link your media library to your box.

3. Right-click the Plex Media Server icon in your System Tray, then choose Media Manager. That should open a new tab in your browser, which is where you'll set up the media you want to share with your Roku. It may take a minute or two before any options appear, so be patient.

4. Eventually you'll see five options for adding media to your library. The process is the same for all, so click one (say, Photos), then click Add and navigate to the folder containing the photos you want to add. Click Add again if you want to include additional folders.

5. When you've finished making your selections, click Add Section. Again, it may take a minute or two for your media to appear in the browser tab.

6. Now head to your TV, fire up the Roku, and choose the Plex channel. You should see your selected media channels, which you can now browse and view as you like.

If you have trouble navigating your media owning to filename confusion, check out Plex's Naming Guide, which is a bit confusing but can ultimately be of some help.

Also, if you have trouble with pixelation, grab the latest version of Plex Media Server directly from Plex.

The other day I received a lengthy contract via e-mail. The document, delivered in business-ubiquitous PDF, was essentially one long form that needed to be filled out. (Or is that filled in? Oh, English language, you so crazy!)

Just one problem: The document was created with certain administrative limitations, meaning I couldn't perform any editing on it. My only recourse was to print the document, complete it by hand, and then scan it back in.

To borrow from Woody Allen, love is too weak a word to describe how I feel about my Roku box. I lurve it.

Email groups are an important part of business life, yet Apple's iOS offers no support for them.

So what happens if you want to send a message to, say, everyone in the marketing department, or a select batch of customers? If you're using an iPhone or iPad, you have little choice but to manually select their email addresses, one after another.

Chrome has some handy ways to keep your myriad bookmarks just a click away, and for Facebook junkies to keep status updates front and center.

Chrome's Bookmarks Bar puts my most frequently visited sites across the top of the browser, just one click away.

It's been almost a year to the day since I adopted an Acer desktop replacement (i.e. a big honking laptop) as my primary PC.

It's a powerhouse, stocked with a Core i7 processor, 8GB of RAM, a Blu-ray drive, and loads of other goodies. For the most part, it's been great.

There are many ways you can use Twitter to help build your business. For example, you can track trending topics, leverage Web analytics, and tap some 50 million daily users.

Of course, let's not ignore the basics. What if you're simply trying to wrangle multiple Twitter accounts? Do you really have to sign out from one and sign into another every time you want to tweet across them?

Your time is valuable. On the Gmail team, we work hard to offer a user ex­­perience that won't bog you down. But we also want to share some tips for be­­ing even more productive with Gmail.

Alex Gawley, Gmail Product ManagerFocus on search, not folders: Google was built on search, and we've aimed to bring that same search experience to Gmail. Studies show that users save time when they search for an email instead of categorizing it into a folder. In Gmail, you can quickly find the exact message you want by typing keywords into the search box, or you can rely on the program's search autocomplete to specify the attributes you want (try typing 'from:[sender]' or 'has photos').

Are you a Facebook junkie? If so, you probably find yourself hopping back and forth between a Facebook tab and whatever else you happen to be doing in your browser. That's not terribly productive.

Should businesses be interested in Pinterest? On the surface, you might not think so: the service would appear to be little more than a showcase for cool jewelry and favorite recipes.

However, it's also a great way to drive traffic to your site. That's according to a new HubSpot e-book: "How to Use Pinterest for Business".

Knowledge is power, especially for anyone looking to start a new business or boost an existing one. Docstoc, home to hundreds of documents and resources for business folk, packs an awful lot of knowledge into its 30 small-business apps for iPhone and iPad.

The apps cover just about every topic under the business sun, starting with finding a job or developing an idea:

I'm a big fan of Chrome's Bookmarks Bar, which puts my most frequently visited sites across the top of the browser, just one click away.

The problem is that I have so many favorites, they don't all fit. Instead, they get squeezed out of view, requiring me to click the little double-arrow on the right end of the Bookmarks Bar. Then I'm stuck perusing a drop-down menu, which takes, like, all day.
