It only sounds like it's related to Thanksgiving, but it's not: where cookies come from. (It's not the kitchen.)
That random wireless network that you can connect to?. Don't.
And, a novel use for One Note.
Nope, that's not a typo - the Tech Entusiast Hour is a new weekly podcast, and I'm one of the four "semi-regular" hosts. Each week we discuss the news of the day, highlight what's exciting, and maybe even rant a little from time to time. You know, because we have opinions. :-)
The Tech Enthusiast Hour is available in iTunes, as well as other popular podcatchers and podcast players. The website also includes shownotes, as well as an embedded audio player so you don't need to do the whole "podcast" thing unless you really want to.
Speaking of Thanksgiving
I'm thankful for you! Thank you for being here, and thank you for supporting what I do. I'm honored.
Where Do Cookies Come From?
Yes, it's very possible to find cookies from websites you've never been to. In fact, I'd say it's almost a certainty.
However, I can't think of a way of telling third-party cookies apart from those sites you actually visited.
It gets surprisingly complex.
Let's look at where cookies come from.
The sites you visit
The most obvious source of cookies are those created when you visit a website.
Resources used by the sites you visit
A less-obvious way to accumulate cookies is from sites that pull resources from more than one web server.
For example, a site like http://reallybigbookstore.com might create and leave cookies under its own name, as above.
That's one source of unexpected cookies: when you visit http://reallybigbookstore.com, you get cookies for http://reallybigbookstore.com, but you also get cookies for http://somerandomservice.com.
That's a third-party cookie. You're the first party, the site you visit is the second party, and any additional sites involved are third parties.
Advertisers on the sites you visit
This is what most people think of when they think of third-party cookies.
Much like the image resources I just talked about, ads are also typically served up from another server. That server, too, has an opportunity to leave cookies on your machine.
Once again, Ask Leo! is a fine example. I have advertising on this site provided by Google's AdSense service. As a result, you may find cookies produced from a variety of domains (http://googleads.g.doubleclick.net being one example) Google uses to provide those ads.
If you have third-party cookies enabled in your browser settings, you can expect to find cookies from advertising sites.
Cookies from pop-ups
Many people block or hide pop-up windows. Even if you do, cookies can still result from them.
I know that this sounds a little odd, but the net effect is that a cookie gets left for a web page you never see.
It depends on how your browser detects pop-ups, what kind of pop-up technology is being used, how quickly they're detected, and exactly how they're blocked, closed, or hidden.
In some cases, the pop-up can exist long enough to leave a cookie on your machine.
Cookies from sites you haven't been to … yet
This might be the oddest of all.
Some web browsers pre-fetch pages that are linked on the current page you're viewing.
For example, this page has links to other Ask Leo! articles. Once your browser has completed displaying this page, it may decide to go and fetch those other pages, just in case you decide to go to one of them.
Why? In a word, speed. If you do click one of those links, the page will come up faster, having already been downloaded.
Now, the question is: if there are links to other sites on a page you're viewing, does pre-loading those sites also allow them to leave cookies? My belief is that that answer is: maybe. It depends on the site, the browser, and a number of other technical details.
But if that happens, you'll find cookies for sites you might never have visited.

There are a number of problems that arise from connecting to an unknown but open hotspot.

Use OneNote for Basic OCR
OCR, an acronym for Optical Character Recognition, is a process that converts a picture of text into actual, editable, text.
For example, you might find a picture of a meme on social media, which may be nothing more than text on a nice background saved in an image format, such as .jpg. Or you might scan a document you've received, which often results in a series of image files, or a PDF containing a series of images — “pictures”, if you will, of the individual pages.
Rather than retyping that text by hand to use elsewhere, you can use OCR to automatically extract the text for you.
As it turns out, Microsoft OneNote, present in Windows 10 and Microsoft Office, has basic OCR capability built in.
