Thanksgiving/Columbus Day and, Internet Safety

It seems that today is a special day – a “double holiday”

Folks, I only have time this morning to wish my readers up there in the Great White North a very happy and joyous Thanksgiving!

And to tell those of you who are lucky enough to get Christopher Columbus day off — I’m jealous!

Here is a tech tutorial from days gone by:

How To Block Websites

Preventing access to websites is called “blacklisting”. (Parents, take note.)

In yesterday’s article, I mentioned that I was going to boycott any website that started showing me image advertising – just won’t go there no more – and I used the Geekspeak word ‘blacklist’. Which prompted a few letters asking how that was done. Today I will show you how it’s done.. and I’ll try to keep the Geekspeak to the very minimum.

If you should decide that you want to block access (called “access control”) to websites you do not approve of, or think may be dangerous to you and/or your family, (and yes, there’s plenty of those) there are several strategies and methods — which you choose will probably be decided by how many websites you wish to block and for how many machines.

Simplest first: The web browser.
Say I just wanted to make sure my own, one machine, here, (or perhaps my child’s) never went to MSNBC, regardless of what I accidentally clicked or Googled (or perhaps I discovered a website that tried to do a “driveby” virus download) – I could add that site to my browser’s Do Not Go There list.

In Internet Explorer:

• Click Tools, and then Internet Options
• Next click on the Security tab
• Now click on the red-circle icon for Restricted sites
• Click the Sites button

[Notice that the URL for the web page you are currently on is – by default – filling the “Add this site” pane… Which is fine if you happened to be on the site you want to block; but you may (probably) want to manually type in URL for the website. You can add more than one – just separate the URL’s by comma+a space.]

• Click the Add button. You will now see the URL(s) listed in the blocked Websites list pane. (You can add as many sites as you want.)
  If you make a mistake, click on the list entry, and then the Remove button.
• Click Close to close that window, then OK to close Internet Options. You’re done.

Other Web browsers can work much the same way (though may use slightly different wording) though my preferred “alternative browser”, Firefox, needs an Add on for this (called Blocksite).

A better way: In the “home computing” environment, it was assumed that it would mostly be parents – wanting to prevent their children from visiting “mature” websites – who would desire to block (blacklist) Internet access. Because of this, most ‘Internet access control’ tools can be found under Parental Controls though, obviously, you do not need to be a parent to take advantage of it.

A good place to get started learning about enabling Parental Controls (to block websites) in Windows is here, Set up Parental Controls (and a brief video can be seen here); and on an Apple Mac, here.

Better yet: The best place to block Internet access is at the front door.. which in computer land is the device known as the “router” (or “wireless router”, or “WAP”), if you have one. Here you can block access by machine, time of day, and more.

This screenshot shows me blocking the website MySpace on a Linksys router, as well as by some “adult” keywords. It is taken from my step-by-step How To article here, Protecting your network–use your router for access control.

Managing your email: eliminating junk (repost)

Much to do and too little time, and so a reposting today.. though I am staying on the subject of e-mail. This is the season of spam, so these tips seem timely. 

I detest spam. Today, I’m going to tell you how to fight it.
And I don’t mean just the random mass mailings of the F@rmis_UtiCal come-ons. I mean unwanted newsletters a well-meaning friend signed me up for… that just won’t let me “unsubscribe”. I mean the “pass it on” jokes (which, allow me to take a moment and ask, does anybody ever find them funny???) and chainletters that some clown forwards to EVERYONE in their address book. I mean the “please take a survey” and “Win a free iPod…” come-ons. I mean the friend/relation who’s trying to convert your politics, and sends you official-looking kook propaganda from Kook HQ.. are you with me?

Tip of the day: Take a few steps and configure your machine to ‘filter’ out the garbage. The first thing to do is start “training” the spam filter that comes with your email account. If you use a free mail service, like Yahoo, Gmail, or Hotmail — or your ISP’s — you can teach your mailbox what to filter (somewhat; it will never be perfect) automatically simply by using the “mark as spam” option or, in some services, the “move to” (and move the offending items to the Junk folder) tool.

If you simply delete the junk, the learning algorithms back at Hotmail Command will not be able to determine why you deleted it (maybe you’re done reading it?), and will make no improvements to your filtering. But if you mark it — this is spam! — notice will be taken of the Subject, Sender, and Sender URL, and that info will be analyzed for ‘spam patterns’. When enough people mark “Great Deal, Act Now!” from “Joe Blow” at “Shady Company.Com” as Junk and as spam — they will, first, mark all email from that source as “suspected junkmail” and deliver it to a different box than your Inbox, and then (and this is the point), with gathering confirmations, block it at the source, essentially putting Mr. Blow out of business (temporarily). Hitting “Junk” instead of “Delete Message” is a public service and, over time, will keep a cleaner Inbox.

The next step is to start working on your blacklist. This is usually done by clicking the Block Sender option. A “blacklist” is a list of senders, or sender URLs, that will not be accepted. An excellent first step is to add anything you receive from the Domain “.info” to your Blocked Senders list. Then add that newsletter that just won’t go away.
I will demonstrate with Hotmail, but these general steps apply to all email accounts… the names and locations of the Settings may be slightly different, but the principle’s the same. (If the Block This Sender option is presented, use it) Click on the mail Options button (in some cases, this will be called “Preferences”)  and then you will be presented with a list of optional settings you can “tweak”, as shown below.

In today’s lesson, we’re looking to out-and-out block a newsletter, so we’ll click on “Safe and blocked senders” (our “white” and “black” lists). Then click “Blocked Sender”.

As you can see, Hotmail Command has already blacklisted many senders. This is because enough people marked these folks (instead of just deleting) as junk mailers. You can also see how to block the newsletter I want to stop. I typed in annoyer@newsletter.com (or copy>paste the URL from a newsletter in my mailbox) and click “Add to list >>”.
This is actually a smarter way to deal with unwanted list-mailings than clicking on the “unsubscribe” link at the bottom of the newsletter itself. Why? Because, while they’re required by law to post such a link, they’re in no way truly obligated to honor it (there’s no enforcement), and you are telling them that your address is valid (and thus valuable to other list users). Add as many junk mailers to this “black” list as you like.

Since there are more steps you can take — the technique described above is a good start, but not the end-all-be-all — to control what appears in your Inbox, I believe I will make this a series of articles, and stop here for today. [Addenda: and I did write a few more; to read them, click here.]

Today’s free link: Have some fun and add useful doohickies to your desktop with Yahoo Gadgets (formerly Konfabulator). From site: “The Yahoo Widget Engine is a JavaScript runtime engine for Windows and Mac OS X that lets you run little files called Widgets that can do pretty much whatever you want them to. Widgets can be alarm clocks, calculators, can tell you your WiFi signal strength, will fetch the latest stock quotes for your preferred symbols, and even give your current local weather.”
