Why you had to come to the website to read the newsletter

Yeah, yeah, I know it's a pain to have to come to the website to read the newsletter, rather than just getting it in your mailbox. But here's the deal: About half our subscribers weren't getting the newsletters because their spam filters were incorrectly tagging it as spam. So we're testing out this new method where we just send you a plain text message that the newsletter is available and then you can come read it on the website, and nobody gets hurt. We'll be checking to see how many of you actually make it over here to read the newsletter. If filters were trashing 4000 of our newsletters, and now everyone gets the newsletter but 5000 of you don't bother to click over to read it, then we'll go back to the old method of emailing the actual newsletter out directly to you.

Free book by the Wizard

In each newsletter for a while one lucky subscriber will win a free copy of the Wizard's new book Gambling 102. The winner last time was subscriber #458, Bill Blackburn, which he's hopefully enjoying as we speak. This issue's winner is Tom Mags. Congratulations, Tom!

Bluejay's Internet tip o' the month: Keeping spambots from getting your email address

If you have a website, it's crucial that you protect any email addresses on it. Most webmasters fail to do this and as a result those addresses wind up in the hands of spammers. Here's how that happens and how you can prevent it.

Just like humans can visit a website, automated programs can visit a website too. These programs are called robots, or bots for short. This is how search engines know what text is on which pages, for example -- they send out bots to constantly scour the Internet and find out what's there.

But there are evil robots called spambots. They visit all the pages they can find looking for email addresses. When they find an address it gets added to a spam list. If you put a plain email address on a webpage, spammers will get it. It's not a question of whether they will, it's question of when. And usually, the answer is "They already got it, right after you put the page up."

So what can you do to prevent spambots from picking up your address? There are a number of strategies but unfortunately each of them has a downside, usually inconveniencing your site visitors in some way. I run down all the popular methods on my page about combating spambots, but let me share with you what I think is the best general method: Javascripting.

With JavaScript you can disguise an email address so it doesn't look like an email address to a spambot. In theory a spambot could be programmed to recognize a disguised address, but for now nearly all spambots are too dumb to figure it out. There are already so many unprotected email addresses freely available on websites, and so few people hiding their addresses with JavaScript, that the bot programmers haven't bothered to make their bots any smarter. Someday if lots of people use JavaScript to hide their email addresses then that could change, but for now, Javascripting an email address provides very good protection.

Here's how you'd code the address sample@WizardOfOdds.com:

<SCRIPT language='JavaScript'>a='sample'; b='WizardOfOdds.com';
      document.write('<A href="mai');
      document.write('lto:'+a+'@');document.write(b+'">');
      document.write(a+'@');document.write(b);
      document.write('</a>');
    </SCRIPT>
    <NoScript>sample(at)WizardOfOdds.com</NoScript>

Notice the <NoScript> tag at the end. If a user has JavaScript turned off then the browser shows what's between the <NoScript></NoScript> tags instead. For that part we replace the @ sign with (at), so spambots can't recognize it. Our visitors without JavaScript will have to type in our email address to email us, but at least they'll be able to see it. But probably fewer than 1% of visitors have JavaScript turned off anyway.

If you have a lot of email addresses to script, you could create a function and then just call it whenever you need it. For example, you could put this in the HEAD:

<SCRIPT type="text/javascript" src="javascript.txt"></SCRIPT>

Then create a file called javascript.js which contains the following:

  function mail(user,domain) {
        document.write('<A href="mai');
        document.write('lto:'+user+'@'); document.write(domain+'">');
        document.write(user+'@'+domain);
        document.write('</a>');
      }

Then anywhere in your document you want to show an email address, just do it like this:

<P>Email us at <SCRIPT type="text/javascript">mail('sample','WizardOfOdds.com')</SCRIPT>
    <NoScript>sample(at)WizardOfOdds.com</NoScript>

If you have unprotected email addresses on a web page, fix them today!

Advertiser Spotlight: Poker.com

Part of my job is to play our advertisers if the Wizard hasn't played there for a while, or hasn't played there at all yet. Unfortunately I'm not much of a poker player. I actually only learned how to play Texas Holdem a month ago and just played a couple of online games for free. This would be my very first time playing Holdem for real money, which was kind of intimidating. But I figured I'd just deposit $50 and not care too much if I lost it. The Wizard pays me well enough that I can afford to blow $50.

My goal was to play for an hour without busting out. Since I know squat about poker strategy I kept a copy of the Wizard's guide to hand strength handy. I downloaded the software but had some problems getting logged in. A message came up that said a Flash movie was slowing down my computer and did I want to stop it? I clicked Yes, but the music kept playing, and the "Logging In" message stayed forever. So I quit the software, started it again, and this time told it to keep playing the movie, and I was able to get in. I registered and made my deposit with NETeller, but I forgot to enter the bonus code BONUS30FREE to get the 30% bonus. D'oh. Don't make that mistake! And the bonus code might change, so check out the Promotions page on Poker.com to make sure you get the right code to enter.

I settled in at a $2/$4 Limit Holdem game. Most of my initial hands weren't very good so I folded them right away, and in fact the Wizard says in his Holdem strategy that a good player will fold most of his hands. But this is one reason I don't like poker -- it's slow. I want to play, play, play! But here I am, folding my hands and watching everyone else play. Of course in poker patience is rewarded, and you can't win by chasing bad hands. So I consoled myself with the fact that at least I wasn't losing money like some of the other players. And when it was my turn to post the big blind at least I could check for free to maybe see the flop.

The other players were incredibly loose. It was rare to see a fold before the flop, and it seemed like an unreasonable number of players stayed through the showdown every time. That's silly -- it's like playing war where everyone gets their card(s) and you see who wins. So I decided to play a little more aggressively, but nothing too crazy. When I finally did jump in with a good hand I not only stayed in but I raised. I figured that that would cause some of the others to fold. I mean, if I'm here folding hand after hand, and I suddenly jump in and raise, then I've either got a good hand or I'm trying to pull off a hell of a bluff, right? But nobody folded. Fine, I thought I might have the nuts so I kept raising. The showdown came and I won. Whoo-hoo!

Then it was back to folding most of my hands, and playing only when I thought I had a good starting hand, and winning most of those. When my hour was up I'd doubled my money to over $100, even without the 30% bonus that I forgot to claim. If I had more patience maybe I should start a new career as a poker player.

I liked the Poker.com software. The interface was pretty easy to use. Especially interesting is the "ALT VIEW" button which gives you a different perspective of the table. And you can turn off the dealer chat so it's easy to see what the other players are saying, though no one said much at my table. And of course, Poker.com offers free-play too, so if you're new and not comfortable playing for real money yet you can easily get some practice in with no risk to you.
