1)Interface design -Too Cryptic, requiring knowledge of macros to work well. 2)Game play -Extremely tedious and permanent character death is part of it's culture. 3)Story -Uh, you make a character and you go around killing stuff. That's about it. 4)Scope -One town and huge frigging dungeon to crawl. 5)Frustrating -Character Death occurs too frequently and load/save is considered cheating by it's community.
Moral of the story, good programming does not make a good game.

First of all, the game incorporates a draconian DRM system that requires you to activate over the internet, and limits you to a grand total of 3 activations. If you reach that limit, then you'll have to call EA in order to add one extra activation.
"Creating" your creatures is pointless (cosmetic only, because everything is based on stats), and brings you about the same excitement as dressing up a plastic doll.
I seem to recall Will Wright giving a presentation where he said that how you designed your creature would determine it's survival. Apparently it's been dumb-down so much that the creature design is mostly cosmetic; depending on the run-of-the-mill stats and dice rolls of the average RPG. The space phase supposedly pales in comparison to Sins of the Solar Empire that boast 500,000+ sales, in part, thanks to no DRM.
Maybe EA will learn a powerful lesson from this. Who knows?
I know that until they get rid of the DRM, I won't be bothering with Spore or any other EA game.
After starting MOO2:
1) Click Multiplayer->Hotseat->New Game
2) Do the game setup as if you where playing multiplayer
3) Keep adding custom human opponents with good race picks.
4) Start the game and play the first turn for the AI then save it.
5) Click Multiplayer->Network->Load Game then load the AI saved game.
6) Click start game after 1 person as joined.
7) Click yes to confirm start with AI opponents.
Another way to do this would be to save your first turn from a multiplayer game then load that with AI opponents. The idea is that with stronger race picks the AI will have less of a disadvantage. On Impossible, with good race picks, the AI plays about as good as the average new player. They still make lots of mistakes but it's better than just using their default race picks.
The main flaw with the MOO2 AI is that it has MOO1 mentality associated with one habitable planet per system. Instead of building colony bases it tries to expand to get the most systems possible. Since colony bases are cheaper than colony ships, this is inefficient. It also errors when building ships; tending to use lots of bombs and few weapon mods. That doesn't work for well ship-to-ship combat. Another problem is that it values a systems position over it's actual worth. It'll populate and defend a poor planet that is near a rival rather than colonize a back-water rich planet.

Peter Diamandis says it's our moral imperative to keep exploring space -- and he talks about how, with the X Prize and other incentives, we're going to do just that.
During the Olympics we discussed the international monitoring effort as China shut down factories and curtailed automobile travel in an attempt to reduce pollution. Now reader Anti-Globalism sends in a story that reveals that monitoring effort to be ongoing, with a bigger mandate: assessing the impact of China's pollution on the US. In fact the problem is bigger still because, as one researcher put it, "It's one atmosphere." Scientists are finding that pollution from, for example, Europe can travel right around the globe in three weeks. "By some estimates more than 10 billion pounds of airborne pollutants from Asia — ranging from soot to mercury to carbon dioxide to ozone — reach the US annually. The problem is only expected to worsen: Some Chinese officials have warned that pollution in their country could quadruple in the next 15 years. While some scientists are less certain, others say the Asian pollution could destabilize weather patterns across the North Pacific, mask the effects of global warming, reduce rainfall in the American West and compromise efforts to meet air-pollution standards."
Wow. I remember reading about this possibility years ago in environmentalist fiction. Interesting that's is becoming a reality just as they predicted it would.

Lately, its seems like the atheists have really come out of their shells and started aggressively attacking religion. I don't consider myself religious but I respect those who do to the extent that they aren't offended.
Do atheist really need to be so rude and obnoxious to get their point across?

Revelation: The Unseen War
Reply to: see below
Date: 2008-07-28, 9:05AM CDT
There is an unseen war that goes on in our world today between t he forces of good and the forces of evil. The good are the people who are working to make a positive difference that will lead to a better world to live in and prosperity for all. The forces of evil are actively working against the forces of good. They want to make living in the world a misery that never ends. Some of them are actually demonic creatures disguised as humans. They may not even be consciously aware of this, which makes them more difficult to detect. Typically they take try to get into positions of power and influence. Some of their common traits are people that greedy, glutinous and constantly working to undermine anyone that is on the side of good. This is often the reason why people who are good have difficulty working for large corporations. What can we do? We have to expose them for what they truly are. If you spot them, make note of it and bring them to the attention of your spirit guide. Your spirit guide works to protect you against the forces of evil. Praying is a way of speaking to your spirit guide. If you find that are being threatened by a demonic creature pray for help. There is a specialized task force of “Light Bringers” that actively pursue demons and their minions in the spirit world. They won’t kill them out right because the demonic creature would just be put into a new disguise, free to do evil again and even more difficult to root out. What the light bringers do is bring these demonic creatures to light in the real world then real justice is dealt through the courts. The demonic creatures are then sent to prison where they can do no harm to anyone. When ever you see someone of power and influence being indicted, there is a good chance that it’s actually a demonic creature.
So what do you think, for real, fiction or just plain nuts?

Sometimes, you have to learn to be more productive if you want to move ahead with your project.
1. Resolve to accomplish something important to you.
2. Schedule time for work, with no possibility for distractions.
3. Gather the tools and materials you need.
4. Work on the project for the time scheduled.
5. Celebrate your little victories (breakthroughs)
6. Get help if you need it.
7. Don’t give up until you’ve accomplished something.

This is God. Today I will be handling All of your problems for you. I do Not need your help. So, have a nice day. I love you.
P.S. And, remember...
If life happens to deliver a situation to you that you cannot handle, do Not attempt to resolve it yourself! Kindly put it in the SFGTD (something for God to do) box. I will get to it in MY TIME. All situations will be resolved, but in My time, not yours.
Once the matter is placed into the box, do not hold onto it by worrying about it. Instead, focus on all the wonderful things that are present in your life now.
Should you decide to send this to a friend; Thank you. You may have touched their life in ways you will never know!
Now, you have a nice day.
God has seen you struggling,
God says it's over.
A blessing is coming your way. If you believe in God, please send to ten
people (including me) please don't ignore this.
You are being tested.
YOU HAVE 2 0 MINUTES TO TELL 10 FRIENDS THAT YOU LOVE THEM (INCLUDING
ME) SO I LOVE YOU! GO!

From what I understand, Dr. Myers and Dawkins were conned into participation by being deceived into thinking it would be a neutral documentary about evolution vs. Intelligent Design. Instead, it's an awful creationist film that tries to claim that academics are behaving like fascist. In my humble opinion, the creationist are the ones behaving badly now. They should just own up to having made an awful film and having wrongfully excluded a genial participant from the free viewing.
You might have noticed the Expelled ads running on my blog. These are because of Google ad words that I signed-up for a long time ago.

These days, our enjoyment of nature is on the decline. More children are playing on their Xboxes instead of playing on swing sets or riding bicycles. Their idea of a nature hike is taking the shortest path possible through the neighborhood to a friend’s house. If we want to instill in our children a good sense of what nature is, then we need to take them to see it in person. Parks and zoos are nice but they are nothing compared to witnessing the wilderness up close.

For many researchers, the Bush administration will be best remembered for the way it has manipulated scientific advice for political ends. The latest evidence of this tactic is a controversial proposal to change the way US air-quality standards are set, according to the Union of Concerned Scientists (UCS) in Washington DC.
When the Environmental Protection Agency said last week that it would beef up air-quality controls by cutting ground-level ozone limits from 80 parts per billion to 75 ppb, it seemed like good news. Ozone can trigger respiratory problems and heart attacks. The new rules should save lives and, by cutting pressure on hospitals, might create financial benefits that outweigh the cost of implementing the changes.
However, around a year ago the EPA's own scientific advisers told the agency that there was "overwhelming" evidence that an even tighter limit of 70 ppb would save thousands more lives. The decision to ignore that advice has angered public-health groups.
Now worse may be to come. The administration wants to reform the process for setting air-quality standards and may allow political appointees to help draft the advisory reports, a job that is currently in the hands of researchers. The UCS fears this will allow the White House to suppress this kind of independent scientific advice in future.
"The interference in science has been a consistent theme of this administration for many years now," says Tim Donaghy of the UCS. "The administration has changed the rules along the way so that, when the next administration gets into office, the role science plays in setting regulations will be greatly diminished."

The golden age of space is only just beginning... Space travel and space tourism will one day become almost as commonplace as flying to exotic destinations on our own planet.
I hope that we have learned something from the most barbaric century in history -- the twentieth. I would like to see us overcome our tribal factions, and begin to think and act as if we were one family. That would be real globalization.

National Weather Service records going back to 1956 show an average of 30 tornadoes a year in Missouri.
But the totals have been higher in recent years.
Last year the weather service counted 42 confirmed twisters in Missouri.
There have been 35 logged so far this year.
The state record was 102 tornadoes in 2006.
State climatologist Pat Guinan said it's difficult to say if climate change is linked to increasing tornado numbers since records go back only to the 1950s. The numbers could also be linked to better detection and verification.
Missouri observes Tornado Awareness Week March 10-14.

Help Wanted: Embedded Engineers Why the United States is losing its edge in embedded systems…
By Mike Anderson, Chief Scientist, The PTR Group, Inc.
Embedded Systems are Everywhere
With all of the cellularphones, portable media player/MP3 devices, global positioning system (GPS)units, set-top boxes, digital video recorders, automobile telematics systems and digital televisions that were introduced over the past couple of years, I suspect that this number is probably on the low side today. We are surrounded by embedded systems comprised of custom hardware and software designs.
An embedded system can be characterized as any device in which you inherently know there must be a computer in there someplace, but you’re just not sure where. This is not to be confused with real-time systems. Systems that have real-time deadlines may or may not be embedded, and not all embedded systems have real-time deadlines. There is considerable overlap for sure, but they are not one and the same.
For instance, a GPS locator has a computer inside. I suspect that everyone knows that. But, we typically don’t attach a keyboard and mouse to it although it’s probably one of the most computer-like of the embedded systems since the user must input addresses in some way. Nor does the user typically vaporize if the device takes 30 seconds to acquire a satellite fix rather than 15 seconds.The GPS is an embedded device, but we probably wouldn’t classify it as a real-time device.
On the other hand, anti-lock brakes are computer controlled as well. Our input into the anti-lock brakes of the car is limited to the brake pedal. The rest of the operation is completely based on other sensors and the environment. It is clearly an embedded system. However, the anti-lock brake system is a real-time system as well. If it doesn’t function within the real-time deadline constraints, then people get injured.
Embedded systems development typically requires a different mindset than we find in the desktop environments. Embedded systems are frequently resource-limited. These systems have low-power processors, possible battery operation, and limited
memory and storage.
Embedded designers need to pack in lots of features, but keep the costs own so the units are affordable.
So, where does the embedded system designer gain this type of knowledge? Currently, companies are paying to have developers learn these concepts on the job.
What many in the embedded systems community would like to see is that new graduates already have some of this knowledge from their college/university education.
The ability of a new hire to “hit the ground running” could save U.S. embedded systems companies millions of dollars each year. This is money that could be reinvested in additional research and development to make them more competitive in the world market, or simply yield a higher return to their investors. Regardless of what is done with the “savings,” the incoming engineer would make U.S. companies more productive.
I only quoted some of the more interesting tidbits.
If you want the full version, here's the link.

A scanning electron micrograph of the aerobic soil bacterium Pseudomonas fluorescens. The bacterium uses its long, whiplike flagellae to propel itself through the water layer that surrounds soil particles.
Words to Know
Aerobic bacteria: Bacteria that need oxygen in order to live and grow.
Anaerobic bacteria: Bacteria that do not require oxygen in order to live and grow.
Bacillus: A type of bacterium with a rodlike shape.
Capsule: A thick, jelly-like material that surrounds the surface of some bacteria cells.
Coccus: A type of bacterium with a spherical (round) shape.
Decomposers: Bacteria that break down dead organic matter.
Fimbriae: Short, hairlike projections that may form on the outer surface of a bacterial cell.
Fission: A form of reproduction in which a single cell divides to form two new cells.
Flagella: Whiplike projections on the surface of bacterial cells that make movement possible.
Pasteurization: A process by which bacteria in food are killed by heating the food to a particular temperature for some given period of time.
Pili: Projections that join pairs of bacteria together, making possible the transfer of genetic material between them.
Prokaryote: A cell that has no distinct nucleus.
Spirilla: A type of bacterium with a spiral shape.
Spirochetes: A type of bacterium with a spiral shape.
Toxin: A poisonous chemical.
Vibrio: A type of bacterium with a comma-like shape.
As the drawing of the anatomy of a typical bacterium shows, the cytoplasm of all bacteria is enclosed within a cell membrane that is itself surrounded by a rigid cell wall. Bacteria also produce a thick, jelly-like material on the surface of the cell wall. When that material forms a distinct outside layer, it is known as a capsule.
Many rod, spiral, and comma-shaped bacteria have whiplike limbs, known as flagella, attached to the outside of their cells. They use these flagella for movement by waving them back and forth. Other bacteria move simply by wiggling their whole cell back and forth. Some bacteria are unable to move at all.
Two other kinds of projections found on bacterial surfaces include fimbriae and pili. Fimbriae (pronounced FIM-bree-ay) are tiny bristles that allow bacteria to attach themselves to other objects or to surfaces.
Pili are tiny whiskers that allow bacterial cells to exchange genetic material with each other.
The term bacterial growth generally refers to the growth of a group of bacteria rather than a single cell. Single cells generally do not get larger in size, so the term growth refers to the reproduction of cells.
Bacteria most commonly reproduce by fission, the process by which a single cell divides to produce two new cells. The process of fission may take anywhere from 15 minutes to 16 hours, depending on the type of bacterium. A number of factors influence the rate at which bacterial growth occurs, the most important of which are moisture, temperature, and pH.
The anatomy of a typical bacterium.
Bacteria are about 80 to 90 percent water. If too much water passes into or out of a bacterial cell, the cell dies. The bacterial cell wall provides protection against the gain or loss of water in most ordinary circumstances. But conditions may be such as to produce an unusually large gain or loss of water. For example, if a bacterial cell is placed in a highly concentrated solution of salt water, water begins to pass out of a cell and into the salt water. The cell begins to shrink and is unable to carry on normal life functions. It cannot grow and will eventually die. On the other hand, an excess of water can be harmful to bacteria also. If water flows into a bacterial cell, the cell begins to swell and may eventually burst, resulting in the death of the cell.
All bacteria have a particular temperature range at which they can survive. For a specific type of bacteria, that range can be very high, very low, or somewhere in between, although it is always a narrow range. Most bacteria thrive at temperatures close to that of the human body (37°C or 98.6°F). But some bacteria prefer cold temperatures as low as freezing (0°C or 32°F), and others require very hot temperatures such as those found in hot springs (50°C to 90°C or 120°F to 200°F). The most extreme conditions in which bacteria have been found are around the hydrothermal vents near the Galapagos Islands. The temperatures near these cracks in the ocean floor is about 350°C (660°F), an environment just right, apparently, for the bacteria that live there.
Another factor affecting bacterial growth is pH, the acidity of a solution. Most bacteria require a pH of 6.7 to 7.5 (slightly more or less acidic than pure water). Other bacteria, however, can survive at a pH more severe than that of battery acid.
Finally, bacteria may or may not require oxygen to grow. Those that do need oxygen are called aerobic bacteria, while those that do not are known as anaerobic bacteria. Anaerobic bacteria have evolved ways of using substances other than oxygen, such as compounds of nitrogen, to obtain the energy they need to survive and grow. Harmless, beneficial, and harmful bacteria
Bacteria can also be classified according to the effects they have on human life. Some bacteria are used to supply products that improve human life, others cause disease, while still others have no overall affect at all on human life.
Helpful bacteria. Bacteria make possible the digestion of foods in many kinds of animals. Cows, deer, sheep, and other ruminants, for example, have a large organ known as the rumen in which bacteria live and help break down cellulose fibers and other tough plant materials. In humans, bacteria known as Escherichia coli (E. coli) occur everywhere in the digestive system, aiding in the breakdown of many kinds of foods. Bacteria are also responsible for the production of vitamin K and certain B vitamins.
Certain kinds of bacteria are also essential in the decay and decomposition of waste materials. Such bacteria are known as decomposers. Decomposers attack dead materials and break them down into simpler forms that can be used as nutrients by plants.
Finally, bacteria are involved in the production of many foods eaten humans. For example, bacteria that cause milk to become sour are used in the production of cottage cheese, buttermilk, and yogurt. Vinegar and sauerkraut are also produced by the action of bacteria on ethyl alcohol and cabbage, respectively.
Harmful bacteria. It seems likely, however, that most people know bacteria best because of the diseases they cause. Some of these diseases are produced when bacteria attack directly the tissues in a plant or animal. For example, fruits and vegetables that become discolored as they are growing may be under attack by bacteria.
Bacteria also attack organisms by releasing chemicals that are poisonous to plants and animals. Such poisons are known as toxins. A familiar toxin-producing bacterium is Clostridium tetani, responsible for the disease known as tetanus. Tetanus is a condition in which one's muscles are paralyzed, explaining its common name of lockjaw. A related bacterium, Clostridium botulinum, releases a toxin that causes the most severe form of food poisoning, botulism.
Some forms of dangerous bacteria live on the human skin, but cause no harm unless they are able to enter the blood stream through a break in the skin. Among these bacteria is Staphylococcus, responsible for the potentially fatal toxic shock syndrome. And although E. coli is helpful within the digestive system, if it is ingested and enters the bloodstream it causes severe cramping, diarrhea, and possibly even death.
Most forms of food preservation, such as freezing and drying, are designed to kill or inactivate bacteria that would otherwise damage food or cause disease. One of the most common methods of destroying bacteria in foods is pasteurization. Pasteurization is the process of heating a food product to a particular temperature for some given period of time. The temperature and time are selected to be sure that all bacteria in the food are killed by the process. The pasteurization of milk has made it possible to insure safe supplies of one of the most popular of all human foods.

SRI International receives funding from DARPA for its CALO AI program
Artificial intelligence. We've been reading and watching science fiction with walking, talking robots for nearly a century. Researchers have been tinkering with it for decades. Have we come any closer to android production factories? Not quite. But the CALO project, under the direction of SRI International, is looking at making headway in basic intelligence for widely used computer software.
CALO, or Cognitive Assistant that Learns and Organizes, is a very ambitious collaboration between more than twenty different organizations. "The goal of the project is to create cognitive software systems, that is, systems that can reason, learn from experience, be told what to do, explain what they are doing, reflect on their experience, and respond robustly to surprise," states SRI's CALO information page.
CALO brings together many experts from different fields of artificial intelligence, like machine learning, natural language processing, and Semantic Web technologies. Groups work on a different piece of CALO, which will be part of the whole functionality.
The project is being funded by the Defense Advanced Research ProjectsAgency (DARPA) under its Perceptive Assistant that Learns (PAL) program. The PAL program is expected to spawn innovative ideas that bring new science, fundamental approaches to current problems, and algorithms and tools and yield technology of significant value to the military. SRI was awarded the first two phases of a five-year contract to develop a personalized cognitive assistant.
While it’s not the artificial intelligence made popular by science-fiction writers like Dick and Asimov, CALO looks to be genuinely helpful to its targeted end-users, government agencies and possibly business.
The PAL project is aimed at militaryuse, but future packages or derivatives of CALO could be very helpful to business professionals that are constantly on the move by helping them schedule meetings and prioritize information.The package can assist users in this way by analyzing patterns in information such as e-mail correspondence.
Information importance can be learned by CALO so that the data is pushed to the top of the list judged by which projects and people it comes from.The system's speech recognition abilities can also put data prioritization to use in meetings. The software can prioritize the data it gathers in regards to the user's projects and create lists and make appointments with involved parties.
One of the strengths of the system is that it can learn the needs of individuals through their habits and interactions, much like a personal assistant of the human kind. Rather than offering canned advice and only acting on human intervention, the software can make assumptions about a user's needs and plan accordingly. It will even be able to reschedule meetings if participants become unable to attend.
Whether or not it would inform other attendees was not specified, but imagine if the system was interconnected to other learning systems on a network, that it could very well inform those assistants, who could in-turn inform their users of the change.
In an intranet situation, such as for a large business or the given military agency application, the system would be incredibly beneficial in that rather than depending on humans, who sometimes aren't at their desks or transpose numbers in a date or time, the software agents could work together seamlessly and accurately. Since the system is a learning system, mistakes are not probably out of the question, but replacing human error and time delay may outweigh the occasional mis-prioritized e-mail -- which the system could learn was mis-prioritized, reducing the likelihood of a similar mistake in the future.
One of the most challenging endeavors for the project is creating a consistent data system that CALO can use for decision making. Gathered data will likely be very disjointed and uncertain. To use this data, various members of the project are working on a probability consistency engine. This engine brings together two of the traditional approaches to artificial intelligence: logic and probability. Probability will be good for finding related data in the chaotic data the software gathers, while logic will better handle the meaning of the data.
Adam Cheyer, program director of the artificial-intelligence center at SRI says of the project, "What’s different and has never been done before in this way is the truly integrated approach of bringing all of these technologies and all of these capabilities into a single system. It takes a system of this size to give you something that can understand and organize so much information.
"While the CALO project will probably not be able to respond to a user's mood, play them in a game of poker, or drive a car, the ambitious undertaking promises evolution in the artificial intelligence field by combining so many different types of systems, methods and applications. Some of the key features for a true AI are in its ability to learn from many different sources of data, adapt in adverse situations and interact with humans on a level that we are comfortable with. While not housed in an attractive mechanical body, CALO could show us the first steps in unified systems capable of such performance.

"In Western culture, where monotheism has been the dominant mode of religious belief, atheism has generally referred to the denial of the existence of a transcendent, perfect, personal creator of the universe. " -Van A. Harvey
Everyone is born an atheist. We’re not born as Muslims, Christians, or Flying Spaghetti Monsterians. It isn't until we're indoctrinated into religion, usually by acceptance of a deity, do we become religious. Atheists aren't required to be nonreligious. There are religions that don't require the acceptance of a deity such as Buddhism.
Modern Humanism is based on the premise that human morality can exist independent of any religious belief system. Many modern atheists believe that religion results in a break-down of humanism. Without religion we would just have evil people doing evil things and good people doing good things. "It takes religion to get good people to do bad things," according to some atheist.
Darwin's Theory of Evolution is often linked to atheism because it gives a rational explantion for the orgins of life without the need for a divine creator.
Today, Darwin's theory of evolution, backed by another 150 years of scientific evidence, lies at the very heart of modern biology. The study of biology has lead to many advances in modern medicine, agriculture, ecology and computer science.
There is a lot of scientific evidence that proves the Theory of Evolution is true. What we don't yet know is if the mechanisms in place to drive evolution are by design or by chance.
I was inspired to write about this from watching Richard Dawkin's video on The God Delusion and by reading this article on atheism by Van A. Harvey.
I'm somewhere between an agnostic and a believer. For me, it's likely that there is a God but I can offer no proof of his existence. Gaining a better understanding of the natural world, so that we can advance science, is more important than religious traditions.
Atheists are a fine group of people that deserve our utmost respect.

Every network administrator should have on hand a security toolkit that can work independently of a workstation’s OS to find malware. Some anti-virus solutions can scan systems over the network. There are a variety of tools out there but there are also some malware programs in disguise as anti-spyware. Just make sure you know that what you are using is going to work for what you need it to do.
If you’re a programmer, the development/testing environment should be separate from the rest of the network, especially if what you’re working on is experimental. You never want to chance breaking working systems with untested code.
First things first: what are mutations? They are accidental changes to an organism’s DNA; they typically happen when the cellular machinery makes a mistake as it copies DNA from one cell to the next. Once a mutation happens, it may or may not be preserved down the generations — whether it is depends on a variety of factors, not least natural selection.
Some proponents of intelligent design claim there is no evidence for continuing evolution in modern times. This article seems to be making a good case that there is. I have no doubt that evolution has happened and is continuing to happen (even if at a slow pace). The real question that I think needs answering is if the mechanisms that are in place to drive evolution are by design or by random accident.

I mentioned in that post, that sometimes virus programmers will create self-mutating programs in order to evade detection by the anti-virus software. Since us security folks tend to nip these nasty little programs in the bud, they don't get a chance to propagate. What if they were allowed to propagate in a controlled environment? Perhaps, over millions of iterations of random mutations a useful program can emerge.
Can computer programs evolve from something simple to something more complex without the presence of a designer or coders? If true, this could prove useful in cutting down on the man hours of programming. I seriously doubt we'll end up with something like SkyNet from the Terminator movies, but it could generate something interesting to study.
What I propose is to create a self-mutating program in a controlled environment. Let the program spawn mutated variations of itself then test those mutations for usefulness. The mutations should be random additions and alterations of program code. Selected pieces of functional code can be also patched together at random. A selector program will then perform automated test on the resulting programs to see if they are worthy of propagation. Those that meet the worthiness test are allowed to propagate and mutate again. This can go on for however long the controlled environment can support the process and resulting programs.
I don't have the facilities to create such a controlled environment, but I suspect some colleges or universities do. It should be something a graduate Computer Science student could do as a class project.

"The designers of software usually aspire to economy of code, clarity in its operation, and powerful algorithms that, with mathematical and logical beauty, do the work of generating a sophisticated result."
He does note that there are still the ubiquitous “Kludges” and hacks in the software we use.
Since PZ is a biologist, he has the opportunity to examine nature's code in detail. He goes on the talk about the "invisible hand of evolution: the evidence of random accidents."
"We tend to look down on the "kludge," the clumsy addition to fix a problem, or the brute force approach of working case by case to force a desired result (although, to be sure, I've seen enough code to know that the awkward hack is ubiquitous)."
However, what we more often see is the action of the invisible hand of evolution: the evidence of random accidents that have been incorporated into the code, of elaborations built of bricolage, a collage of bits and pieces assembled into a larger structure. Life is a collection of kludges taped together by chance and filtered by selection for functionality; it all works magnificently well, but if you look under the hood you are simultaneously appalled by the sheer inelegance of the molecular gemisch and impressed with the accumulation of complexity.
It would be inappropriate for me to critique PZ's essay from a Biologist standpoint. My only exposure to biology is reading PZ’s blog and high school biology class.
I am a programmer and have been working in the IT industry since 1996. I can tell you from first hand experience that once a code-base reaches a certain size and level of complexity, logical elegance in design becomes less and less of a concern. The emphasis becomes, "Just make it work."
At the start of the project the design team works out a beautiful object-oriented model of all of the components and various interactions. This is done to help manage the complexity and make the system easier to maintain down the road.
Once the main design phase is over, the grunt work of actually implementing the system may or may not follow the exact specifications laid out by the designer(s). Sometimes features are added in the middle of a project and the only way they make it in is to come of up with a kludge or quick hack.
After the software goes into production, the customer often comes back asking for additional changes to meet their specific needs. This often results in even more kludges and hacks. What starts out as logical beauty begins to show a few warts and wrinkles as time goes on. The visible hands of coders can result in an evolution of sorts of the software system.
You can also write a program that randomly mutates itself. Since the program is in essence data, that data can be over-written. In this way, a computer program can mutate into something that looks different from the original. Virus programmers sometimes write this functionality into their creations to get past the detection software. That functionally still requires a designer.
My point is that just because something looks like it was a patched together collection of hacks, doesn't mean it started out that way. Is evolution by design or by random accident? I'm not making any assertions either way. I know that a program that is the result of random self-mutation seldom does anything useful or elegant. The fact that it can change itself is a product of design

Virgin Galactic has unveiled a SpaceShipTwo (SS2) design, created by Scaled Composites, that harks back to the NASA/USAF Boeing X-20 Dyna-Soar glider of the 1960s, while Scaled's carrier aircraft, White Knight II (WK2) has been given a twin-fuselage configuration.To be launched on a Lockheed Martin Titan III rocket, Dyna-Soar was for hypersonic flight research but the programme was cancelled before the first vehicle was completed. Some of its subsystems were used in later X-15 flight research and Dyna-Soar became a testbed for advanced technologies that contributed to projects, including the Space Shuttle.
Here's a tip; buy a thermos, the kind that can store hot drinks (coffee, tea, etc) and helps to keep it hot for hours at a time. When you heat water for coffee or tea, put the excess hot water or hot drink into the thermos for later use. This way you don't waste as much water or energy when you're thirsty later in the day.
I use a thermos for taking herbal tea to work since we don't have many other tea drinkers. Just one tea pot full of hot water is good enough for 3-4 cups of hot tea.
