What will the last two lines print. Will they be the same?


SELECT @first = ISNULL(@test, 'test')
SELECT @second = COALESCE(@test, 'test')

PRINT @first
PRINT @second

What do you think?

One complaint about rel=”nofollow” is that you just might want to reward people who post related and constructive links in the comments section of your blog.

My answer to that is to implement reverse comment moderation. As far as I’m concerned, I’d like comments to appear immediately on my site. However, I don’t want them getting Google juice. Call me vindictive if you will. I know it won’t stop comment spam. But I do think it’s a fine complement to other methods that do attempt to stop Spam

Instead, I’d be happy to go in and remove rel=”nofollow” for all links within a post. Ideally there’d be a really nice interface for it. A simple checklist of the day or week’s comments and I could check them off and post it.

Then again, I don’t really care that much. If you really post a comment with something worthwhile, I’ll just mention it in my next blog entry sprinkling a tiny bit of Google juice on your link. (And I do mean tiny. I’m part of that long tail Chris Anderson talks about).

I’m proposing a new attribute. Place rel=”willfollowforfood” in your link and I will index it in exchange for food.

There’s a debate going on about how effective the rel=”nofollow” solution really is. Some believe that Google is flattering itself by thinking that the primary motivation for comment spam is Google juice.

I do not believe that rel=”nofollow” will stop comment spam as I’ve stated before (though I’ve applied it myself). Getting their links out there may be motivation enough. However I think it will have a bigger impact than some people think.

In terms of sheer economies of scale, I don’t think comment spam is like regular email spam. Sending an email to millions of users is very easy both technically and costwise. Buy a list and start sending. Comment spamming millions of websites takes a lot more work.

The primary benefit to comment spam was that a sites page rank increased. Think of it this way, if I spam 100 sites, that might increase my exposure a little, say 10,000 people come via those sites. But suppose those 100 sites increases my page rank and now scores of users are finding my site via Google. That’s where the big financial impact comes in. Those 100 sites might now bring in 1,000,000 users. (I’m pulling these numbers out of my ass but I’m probably not too far out there).

Removing the Google juice increases the comment spammer’s work by a factor of 10 or even 100 to get the same financial impact. This might not stop the comment spammer, but it will hopefully put a damper on their activities in the long run.

From now on, no person, whether an individual or a body corporate, shall look directly upon my person nor speak of me without my written permission. I was inspired to enact this notice by this tidbit from Raymen Chen.

A Dr. at Cardiff University has created a scientific formula to prove that January 24th will be the worst day of the year.

The formula for the day of misery reads 1/8W+(D-d) 3/8xTQ MxNA. Where W is weather, D is debt - minus the money (d) due on January’s pay day

  • and T is the time since Christmas. Q is the period since the failure to quit a bad habit, M stands for general motivational levels and NA is the need to take action and do something about it.

Well I could have told him that without this fancy formula. January 24 is the day after my 30th birthday. It’s all downhill from there. ;)

MonkeyHello y’all. In case you haven’t noticed, links in my comments now have a rel=”nofollow” attribute attached. That means no more Google juice when you post a list of links in the comments section of my site. So you can stop now. No really. Move along. No point in comment spamming here.

Ok, since you’re still here, you’ve apparently noticed, this hasn’t placed a magical barrier around comment spamming. You’ve forced me to unveil my next weapon against comment spam. When posting a comment, my server will obtain your IP address and location and unleash a legion of angry lonely Ninjas to dispatch anyone found at the address. Not to mention that my server will start streaming Yanni’s greatest hits to your browser. If you make me really angry, I’ll send Yanni himself. But only in rare occasions as his hourly rate burns a hole in my wallet.

Besides, your comments will be removed from my site expediently. I have a crack team of monkeys in Nigeria who are highly trained to identify and remove comment spam from my site. For one banana a month, comment spam is cleansed from my site. (Sorry to American monkeys for offshoring, but I really couldn’t afford the standard five banana rate).

captcha comments edit

I read an article recently that talked about how ticket scalpers have a 10% success rate against TicketMaster’s CAPTCHA controls. That might not seem like a very good rate, but when you have an automated process attacking it, 10% is plenty good.


CAPTCHA for the uninitiated stands for Computer Aided Program to Tell Humans and Computers Apart. It’s a method or program used to distinguish between a computer and a human.. The most popular type out there is the letter or word warping kind you often see when signing up for a web based email account.

It turns out that character recognition programs are getting better by the second. As cool as these type of controls are, I think a simple text based semantic approach might prove stronger. For example, asking a simple question such as “RGB Stands for Red Green and what color?”. If you can’t answer that question, I probably don’t mind the fact that you’re not commenting on my blog. ;)

The one problem with this question approach is that you can’t generate these questions automatically. You’d have to create a decently sized database of questions. However, the benefit is that language recognition is still very difficult for a computer. Especially when dealing with mispellings.

What is the nomber after foure?\ Waht is the nmuber aeftr fuor?”

You can probably answer that easily. A computer is going to have a much more difficult time.


In any case, rel=”nofollow” and CAPTCHA aren’t going to be the final solution. At some point, our blog engines will have to learn to tell the difference like a human would. One approach is to enlist the concept of trust. If you’ve been subscribed to my blog a while or I’m subscribed to yours, I’ll let your comments in no problem. Otherwise your comment will have to pass a series of heuristics to get in the door.

Humans, feel free to comment…

UPDATE: It’s worth noting that Bayesian Spam Filtering is not a silver bullet. Spammers have gotten smart and are now employing a tactic called Bayesian Filter Poisoning. By including random legitimate words along with their message, they either get their message through, or cause you to teach your filter to regard legitimate words as suspect.

I’ve seen a particularly tricky approach via email where they used a font in the same color as the background. Check out the following quote. Highlight it with your mouse and see what it says.

This looks does like Spam to the human naked eye. BuyecheapodrugssandtimprovesyourasexOlife. But it doesn’t to the computer

My neighbor Chris is working for the Army Corps of Engineers on several construction projects in Iraq to help rebuild their infrastructure. While they’ve enjoyed some success, they also have their fair share of setbacks.

Infrastructure also provides the insurgents with an attractive target. Around Basra, they regularly blow the oil pipelines that run to the port of Umm Qasr. If you stand out at the army base for awhile in the evening, you can usually spot a billowing cloud of smoke in the distance marking the most recent hit.

I applied a patch to my .Text installation as recommended by Scott Watermasysk in this entry of his blog.

New comments will now have the rel=”nofollow” attribute applied, thus preventing Google (and others) from indexing the link and giving the comment spammers a higher page rank.

I found a slight problem with the patch. It works for URLs within the body of the comment but if the user specifies a URL in the URL field, it doesn’t modify that URL. Thus you can still comment spam me, but only one URL at a time. I posted a comment in Scott’s blog about this.

In any case, I doubt this will stop the comment spam anyways. It may well be good enough for the spammers to continue. Despite the fact that their Google page rankings won’t increase as a result, by spamming enough sites, they’ll get enough exposure on enough blogs (et all) that enough users will click through. It’s the same way with email spam. All it takes is a very small percentage of suckers to bite.

This does take away one of the key motivators to comment spam. I will probably add a CAPTHA tool later after some investigation.

Schwimmer makes some good points in his clarification to his decision to ask Bloglines to remove his feed. A few points in particular warrant further discussion.

Creating the free content for advertisements that Bloglines will sell to other trademark law firms. This isn’t baseless conjecture - read this discusssion of Bloglines’ plans for advertising keyed to the content of blogs. At least with Google’s contextual ad program, the blog creator gets some money.

The question I have is how is this different than if say FeedDemon or Newsgator decided to release a free version of their aggregator that included targeted ads. Tyme White claims…

there is a big difference between Bloglines search/preview feature where anyone can view a blogs content and someone adding the feed for private viewing. The argument of desktop readers having ads is completely different - that would be for private viewing only by the user and the ad would NOT be on the feed, it would in the software.

Seems to me it’s only a difference in mechanics. Most aggregators contain search features as well. Wouldn’t be hard for them to include targeted ads. Not only that, it’s still making money off your content. Even a desktop aggregation company could print the following ad…

Find out how our sales team can help you reach you reach new customers with targeted advertisements on ACME Aggregator. Contact sales@acmeaggregator.com for more information.

In my view, there’s a big difference in what Bloglines is doing and some website blatantly ripping your content. I can see the problem if Bloglines was a profit motivated legal website and the main content of the site was taken from legal blogs that provide feeds. With Bloglines, the primary usage is for private users to subscribe to feeds. Yes, your content is available via search, but it’s the same as with Google. Likewise, don’t you want people to find your content, regardless?

Tyme goes on to say…

The bottom line, if money is being made off of a feed it could be deemed commercial use and you should receive permission from the author before redistributing unless the content is considered public domain.

Does that mean Google must ask permission to display your site in search results which might contain ads for your competitors (which was recently ruled completely legal).

Suppose you send copyrighted email to a gmail user? Does it infringe on your copyright that Google can target ads to be displayed alongside your email?

I don’t ask these questions to be contrarian, but to really understand the issue. As I see it, yes martin is right. He does have the right to control his content. But true wisdom is knowing when one should excercise a right. As Scoble points out,

…(by the way, how come you guys aren’t yelling about Google’s caching? Did you see that all your pages are cached over on Google? That breaks with traditional copyright law too, but so far we’ve been cool with that too. Why? It helps everyone.

My advice to Martin is that yeah, you’re right. You have a copyright over your content, but think about the big picture. You’ve definitely got yourself noticed. Now let Bloglines use your content for fun and profit, become a blogging hero, and watch your own clientele list and profit grow as a result. Everyone can win in this situation. Don’t try to force a new technology to fit within the confines of an outdated copyright system that’s winded and unable to keep up.

Probably the best thing to come out of all this is a discussion of copyright as it pertains to an entirely new medium. Let’s hope the right decisions are made that reflect the cooperative nature of RSS.

Saw this on Scoble’s link blog.

THE ACCIDENTAL BLOGGER is what I’m going to call what happens when a blogger writes a post that accidentally becomes far more important to their site than ever intended. I certainly never intended that racing frogs and the death test would be among my more popular threads, but there you …

[Via Scoble]

A while back I blogged about a hilarious Dave Chappelle skit called (and if you tend to read aloud, I recommend reading the next words silently) “The Niggar Family” (and please note that the derogatory N-word is spelled differently lest you flame me miserably).

Unfortunately, the search word that brings the most visitors to my site via Google is “Niggar”. Egads! A mispelling of a most offensive epithet is NOT what I want to be associated with. I can only hope that these users are indeed searching for the skit video and aren’t a bunch of bad spelling ignorant racists.

As you might guess, the search phrase that brings the most visitors is “Niggar Family”. That post has seen 7881 web views according to .Text’s reporting. In second place is the phrase “German Car Video” (25,981 web views). You’ll just have to watch it to see why.

My most popular post of all time is “Nerds Protest The RNC” (41,635 web views). It’s the photo of the sign with the html tag “</bush>.

So like Molly, I’ve had my share of being an Accidental Blogger. The day I write a technical post (the intent of my blog) that matches those numbers is the day I say to myself that haacked.com has done good (thus exposing my poor grammar skills).

I love me some electronic gadgets.

Take today for example, I was in the middle of a fantastic pick-up soccer game under clear blue skies when I received a page on the company Treo (I had it by the goal). A socket server service was down and needed to be restarted (long story, it will get replaced by something yours truly wrote).

A few years ago that probably would have required me muttering a litany of swear words under my breath while driving in to restart the malcontent service. But not this time baby! We live in the digitial wireless mini-this and mini-that age.

I took over as goalie for a bit, busted out the Treo, navigated to our secure administration tool on the web, and restarted that sucker (all while blocking a few deadly shots on goal). Life is good.

I’ve just removed Martin Schwimmerfrom my subscription list. Why? Because he doesn’t want his posts reprinted in Bloglines (and, I assume, in sites like my link site).

The real trick here is: if you don’t want your full posts reprinted somewhere else, don’t put them into RSS. That’s one reason most commercial sites don’t include full content in their feeds.

I don’t mind that Bloglines reprints my content and I don’t mind that anyone using an RSS News Aggregator looks at my content without seeing my design or my navigation links or my email address or cell phone number.

If I did care, I’d switch my RSS feeds to only shove out partial content, or I’d delete my RSS feed altogether.

[Via Scobleizer: Microsoft Geek Blogger]

After reading Martin’s post and his reasoning for contacting Bloglines, it sounds like much ado over nothing. In my humble opinion, he’s making a myopic mistake in action and reasoning.

First of all, if he’s going to provide an RSS feed for his blog, his argument against Bloglines is disingenous. His RSS feed is stripped of his contact info and branding as well.

I have a simple solution for him, simply put your contact info at the head or tail of every blog post. Problem solved! You can now take a step forward instead of a step back. If you’re trying to get your promotional information out there, why make it harder for others to receive and consume. Especially given the popularity of bloglines. It just seems so short sighted to me. Then again, never underestimate the power of controversy to get you noticed.

Here’s an example of how to do a tagline:

This post was brought to you by Haacked, please send money. <— Sample of a promotional tag line.

We have perfect timining. We arrived in Los Angeles this morning to beautiful blue skies. Rumor has it that it’s been raining for the past four days or so, but I don’t believe it.

It’s nice to be home after a wonderful vacation. We picked up Twiggy from the doggy day care and are now fighting the effects of jet lag. I am also struggling with my new addiction, NeverWinter Nights Platinum edition. As if I don’t have enough on my plate with RSS Bandit Dev, Contracts, Book Proposal Reviewing, and general reading. Oh yeah, and my day job.

Due to my love for sake, my father-in-law gave this bottle to me as a parting gift.

Castle Sake \ top exposed \ *hic* I’m ready to shtorm the castle shir *hic*

He also gave me two bottles of “Negori” Sake (not pictured). This is a milky looking sake that contains the live cultures used in the sake making process. I absolutely love it, but I learned that it’s more of a commoners drink and not served in many of the fine restaurants.

Now I just need some people to share it with when I get back to LA.

Do you remember that episode of the Simpsons (number 24 to be exact) where Homer takes his family to a Japanese restaurant and orders the blowfish? Yeah, me too.

My father-in-law took us out to a very traditional Japanese dinner as a celebration of TY’s (Akumi’s brother) impending wedding. Here’s a picture of our room and Akumi listening attentively as our server tells her the menu (or something like that. I couldn’t understand as it sounded like a bunch of jibberish to me. I think they call it “Nihongo” or “Japanese” to you and me).

Japanese Dinner \ And for the main course, I will feed you poison.

The food was outstanding and very delicately prepared. At least for the two microseconds before I clumsily destroyed my dishes with my two chopsticks of death.

\ Thar’s gold in them there soup.

Much to our surprise, we were served Fugu. It’s not a typical part of this meal and isn’t listed on the menu, but apparently Akumi’s dad is such a regular he received a bit of special treatment.

Now back to that Simpsons episode. Homer discovers that he’s eaten poison and is going to die. He makes a list Homer’s List of Dumb Things I Gotta Do Today Before Dying (the first item on the list is “Make List”) and hilarity ensues.

Fugu is an ugly fish that is capable of inflating itself and exposing protective spikes (think Finding Nemo). Those spikes contain tetrodotoxin, a poison that is 1200 times more lethal than cyanide. It only takes a small amount to kill a person and each blowfish contains enough to kill 30 people. It is the one delicacy that is not allowed to be fed to the emperor (and no wonder). Approximately 100 people die from it in Japan yearly, though mostly in outlying areas where fugu is prepared by those who are not trained to prepare it. This is probably less than the number of people who choke and die on mochi rice each year.

Blowfish (fugu) \ Meet the maker of your doom.

But I happily dug in. In the picture above, the plate is covered in Fugu sashimi, the main meat of the fish. At the top left, the white stuff is the skin of the fish (the best part in my opinion) and at the right is something explained to me as the “stuff between the skin and the meat”.

Apparently the word “delicacy” in Japanese means “Food that has very little taste. What little taste it has, is too subtle for your western tastebuds”. The fugu meat had a very subtle taste and a very slight chewy consistency. We dipped it in a sauce to give it more taste. Later we were served fried fugu (not pictured) and that was very delicous. Cooking it brings out more flavor.

One of my favorite parts of this meal was the expensive bottle of sake we consumed. For only 10,000 yen (around $100), we enjoyed this very smooth and clean concoction with a slight fruity aroma and taste.

Sake \ Mmmmm Sake

I’ve become quite a connoiseur of sake, so much so everyone wonders if I’m secretly Japanese myself.
