Cloned Food Silliness

by RMD 28. December 2006 12:50

The media is in quite the frenzy over the upcoming FDA announcement that declares meat from cloned animals to be safe for human consumption. Everybody seems to be against the decision. (Which, by the way, isn't really a "decision" so much as a finding of fact, which makes people's anger over this all the more funny).

Dolly the cloned sheep But why would cloned animals be dangerous to eat? All they are is the equivalent of man-made identical twins, albeit twins born many years apart, which doesn't happen all that often. :)

I wonder if the people objecting to this are really aware of what cloning is all about. Do they think that natural twins are also unfit for consumption? If not, why do they make a distinction for the man-made variety?

My hunch is that the people who are against this fall into one of three categories.

 

  1. People who are against us "playing God"
  2. People who don't really understand cloning or confuse it with genetic modification
  3. People who stand to lose money due to the first two types of people not buying their stuff anymore

I suspect that the market for cloned meat will be primarily limited to the very high end suppliers which provide meat for savvy consumers and upscale restaurants. Breeders will be able to clone their finest cattle (or whatever animal) and sell it at an increased price. The same people who buy Kobe beef will buy meat from cloned animal known for its tastiness and quality. (Assuming they're not members of groups 1 and 2 mentioned previously.)

Furthermore, unlike mad cow, cloning isn't contagious. Just because a rancher has one or more cloned cattle doesn't mean that they can't sell non-cloned animals as well. So I'm not exactly sure why other countries would ban US animal products since we could simply not sell them the cloned animals.

Whatever. I welcome cloned animals into my diet. I want my baby back... baby back... baby back cloned ribs, damnit.

Windows Vista TCP/IP Performance

by RMD 8. December 2006 21:07

Among the many improvements in Windows Vista is an entirely rewritten TCP/IP stack. The new stack support some very cool stuff such a PNRP, IPv6, Teredo, improved QoS support, and a new congestion control protocol called Compound TCP, or CTCP for short.

CTCP promises to greatly increase the efficiency of high latency connections. Most of today's congestion protocols (which determine how fast to send data over the network) leave a great deal to be desired when it comes to dealing with high latency connections. They end up under utilizing the available pipe. What does that mean?

It means that if you have a connection that spans a long distance, like from Boston to Los Angeles, even if that connection has a "fat pipe" (it can support very large transfer rates), you'll often get significantly less than the maximum transfer rate. So while you should be getting 8Mb/s, you might actually only get 5Mb/s. The reason for this is that, for most congestion protocols, high latency is a signal to slow down because something is wrong, when in fact it's just the nature of the connection.

CTCP handles things differently. Honestly, the math is way over my head... but the end result is something we can all comprehend: MORE POWER... er... speed... um... faster downloads.

Since I'm running Windows Vista on my trusty IBM T42P laptop, I decided to kick the tires on this fancy new TCP stack. The first thing I had to do was enable CTCP, as it comes disabled by default. To do this you must enter the command shown in the screen shot to the right. Be sure to do this in a command prompt running as Administrator.

The exact command is: netsh interface tcp set global congestion=ctcp

Once you've done this you should be enjoying your new super-fast net connection, right? Well, not so much. The testing that I've done shows almost no change in my transfer rates. I conducted my tests using Speakeasy's nifty speed test page. These numbers are the average of 5 tests each for both my transfer rates from Boston to NYC, and from Boston to LA.

As you can see, while I gained a bit during downloads from NYC, I lost a bit during uploads. Strangely enough, the much higher latency connection to LA seemed to only suffer from turning on CTCP.

So what's the conclusion? Well, I really doubt I created the proper environment to showcase CTCP. I know Microsoft's tests show that it can more than double the bandwidth available on certain connections. I'm also less than confident that using a flash speed test app was probably not the most scientific way to test this. Furthermore, a Comcast cable connection (8Mb/768Kb) is also probably not the best way to judge CTCP's effectiveness.

So my conclusion is that I'll defer to the judgment of people who are more qualified to test this than I am.

Damn Addictive Flash Game Called Dice Wars

by RMD 8. December 2006 16:35

I've been playing a lot of this damn addictive flash game called Dice Wars. The game is very similar to Risk.

As far as I can tell, a combination of a conservative attack strategy and picking a map where your "areas" have limited avenues of being attacked, are key to winning the game. And, as would be expected with a game called "Dice Wars", the element of chance can mix things up a bit.

Good stuff.
