What do games have that we miss in UX and Web design? Games have stunning graphics, missions, high scores, etc.. But adding any of those to our designs does not necessarily provide a better user experience — in many cases they’re frippery. What we are really looking for is what those elements bring to the games. Gamification is here to stay, and unfortunately many people will continue to use it the wrong way.

When all you know is SQL Server, it’s tempting to try and solve every problem with a relational database, but often it’s not the best tool for the job. Today I want to introduce you to an excellent example of this, the ‘Database As Queue’ anti-pattern. It’s a common specimen that you’ll find in the wild in many enterprise development shops. “When all you have is a hammer, every problem looks like a nail.”

"Use the right tool for the right job." -- Scotty et al
Many times a database-based queue is the right tool and I would consider it before resorting to message queueing.
I know very little about message queueing (I've never developed such a system, but I've had to maintain some), but they seem much less flexible and more brittle than database-based systems.
Perhaps the systems he's seen have other problems. Or message queues are the only hammer he has.

Message queuing through shared memory is very fast and can be flexible. I have seen this work well and would recommend it over a database solution.

But it duplicates data and in a database-based system you can have a dynamic set of listeners.
Shared memory can't be used between servers, can it?

With multiple applications on a single server, no the data is not duplicated. I don't see why you cannot have a dynamic set of listeners watching shared memory.
PIEBALDconsult wrote: Shared memory can't be used between servers, can it?
No, of course not. However, you could use a publish/subscribe pattern. You could use Apache's HTTPComponents to build a transport system or you could build the system using named pipes which is one of the methods SQLServer uses.

Yes, it is. It's in the database and in the queueing system.

Also, you could use MSMQ on Windows systems to handle messaging or IBM Websphere MQ on Linux.

A hacker can put a lot of code together in a hurry but if a change is needed the code has to be completely rewritten. A programmer may take a little longer but if changes are needed they are more quickly and easily installed without the need for a complete rewrite. But is that the only way to express the difference? Or is there a real difference at all? What is the difference between Hacking and programming?

I think "quick and dirty" fits well...there's a reason VS groups comments starting with "HACK" with those starting with "TODO".

A rather sweeping generalization. A competent and experienced programmer can 'hack' code together quickly to do a job and it may not require anyone to go back and fix it. On the other hand a whole group of 'programmers' can still produce crap code.

Hacking on the C code of giflib after an absence of nearly two decades has been an interesting experience, a little like doing an archeological dig. And not one that could readily be had elsewhere; nowhere other than under Unix is code that old still genuinely useful under any but carefully sandboxed conditions. #ifdef you remember any of this, you're getting old like me.

The iPad’s light, sleek, simple construction belies its complex origins. There’s a lot of stuff in the iPad: aluminum and glass, of course, but also other heavy metals and toxic chemicals. And manufacturing each 1.44-pound iPad results in over 285 times its own weight in greenhouse gas emissions. The manufacturing of and material used in the iPad are two reasons why the iPad must be made in China—and not just in the ways you’d expect. It's not just about cheap labor.
