Archive Classic: Evolution Goes Forward, Backward and Sideways

first_img(Visited 86 times, 1 visits today)FacebookTwitterPinterestSave分享0 The story of evolution in easy-to-understand language. Try the exercise in the commentary.According to an article by Becky Ham on MSNBC, evolution can make things more complicated or less complicated.  She referred to iconic cartoons that show the progress of evolution from slime to couch potato.  “It’s just a joke, but the idea that life starts simple and gets more complex over time persists even in scientific circles.”  One counter example, though, is the origin of single celled life.  Archaea and bacteria may be stripped-down versions of eukaryotes.  This idea from David Penny (Massey U, NZ) suggests that eukaryotes appeared first.Penny said, “We do think there is a tendency to look at evolution as progressive.  We prefer to think of evolution as backwards, sideways, and occasionally forward.”  Penny and his colleagues deny the popular hypothesis that eukaryotic cells emerged from the fusion of earlier, simpler life forms.  “Although the idea seems contrary to our cherished notion that evolution makes organisms more complex,” Becky Ham (no relation to Ken Ham, as far as we know) wrote, “Penny and colleagues say it’s possible.”Well, then, it follows that in evolution, anything is possible.  Penny’s colleague Chuck Kurland [Lund U, Sweden] provided more examples of simplification that “illustrate the Darwinian view of evolution as a reversible process in the sense that ‘eyes can be acquired and eyes can be lost.’  Genome evolution is a two-way street,” he said.Visualize a hockey puck on a frictionless surface infinite in all directions, moving about in various ways.  The concepts of forward, backward and sideways lose all meaning.  The same is true in relativistic Darwinland, where an incoming asteroid can cause extinction but also a boom in emergent innovation (see Fox News). In the overall scheme of things, does it matter which direction is forward or backward?For decades, most Darwinists have taught as fact the myth that eukaryotes are a more complex product that emerged from the fusion of simpler, more primitive microbes.  Progressivism is built into such a notion.  Now, if eukaryotes just appeared suddenly, then became stripped down into the other two kingdoms of microbes, then Darwinian miracles of emergence allow for anything.  Why don’t we extend Penny’s theory and conclude that bacteria are stripped-down humans?  (Sorry; that didn’t come out right.  Some people on the beach, though, do resemble amoebas.)Exercise: Read the following paragraph aloud:The Story of EvolutionEvolution explains more complexity, and more simplicity.  It explains why flight arose in some birds, but was lost in others.  With evolution, organs and genomes can become more complicated, or more streamlined.  Eyes emerge through evolution, but eyes are also lost by evolution.  Evolution makes the cheetah fast but the sloth slow.  By evolution, dinosaurs grow to skyscraper size, and hummingbirds grow tiny.  With evolution, peacocks grow more flashy and crows more black, giraffes tall and flatworms flat.  Evolution explains predator and prey, loner and herder, light and dark, high and low, fast and slow, profligacy and stinginess, terrorism and altruism, religion and atheism, virtue and selfishness, psychosis and reason, extinction and fecundity, war and peace.  Evolution explains everything.Now substitute the meaningless word Gribbleflix for Evolution and read it again.  There you have it: the world’s most successful, all-encompassing theory.  Nothing in biology makes sense except in the light of Gribbleflix.  Don’t let the anti-Gribbleflix people sneak their dogma into the schools.  Gribbleflix is science.  Gribbleflix is a FACT!last_img read more

How to Cheat* at LEED: Part 2

first_imgExemplary or “Double Secret” Credits – Needles in the HaystackThroughout the LEED for Homes rating system there are points for “Exemplary Performance.” When you have done more than enough work to max out the points available in certain credits, you can take extra points in the ID section, although you can only take a total of 4 ID points, so don’t overdo it without getting the credit.1. High-Performance Clothes Washer. If you use the performance path (as many people do) and you put in a very efficient clothes washer, you get to take 1½ ID credits. If you try to put in anything but 1 point in an ID credit line on the spreadsheet, you get an error message, but it will accept the 1.5 points and move on.2. Extra Pest Control. Once you max out your 2 points in this category, you can take ½ point for each item, up to a total of 1 ID point.3. Extra Irrigation Measures. Just like Pest Control, after you max out this credit, you can take ½ point, up to a maximum of 2 points in the ID section.4. Framing Efficiencies. Following on the heels of Pest Control and Irrigation, if you max out the framing efficiency credits you can take extra points in the ID section. Documentation – Everyone’s AlbatrossJust like voting in Chicago, do your LEED documentation early and often. The biggest problem that project teams have is getting their documentation together. When done as the job progresses, it doesn’t become a huge mountain to climb at the end, when everyone has moved on. I am the rater on projects that have been finished, sold, and occupied for over a year, and I’m still waiting on paperwork from my clients. If you pay for the certification, you may as well go ahead and get it. And Don’t Forget the Prerequisites!LEED does have a few critical prerequisites – no matter how well you do, if you miss just one of these, you are out of luck. Make sure you understand what is required and that it gets done in the field.1. Durability evaluation form and checklist. I have problems with this particular requirement of the program, but it’s a rule that you have to follow.2. Erosion control. Most of this is a code requirement, but if it isn’t where you are, make sure to do it.3. No invasive plants. Get the list from your extension service and make sure none get planted on your site.4. Energy Star. Unless you use the prescriptive path, the house must meet the requirements for the Energy Star Homes program, although it doesn’t actually have to be labeled as such. Until the new LEED for Homes version is released next year, you don’t need to move to Energy Star Version 2.5 or 3, but that will likely be required in late 2012.5. Framing waste order factor. This calculation has to be done for each project. I am dubious of its value, but you’ve gotta do it.6. FSC letter to vendors. Write it and send it out to everyone who sells you wood for the job.7. Waste management planning and documentation. Check into recycling opportunities and either save all your dump manifests or get monthly reports from you haulers and recyclers.8. Combustion venting. Doors on all fireplaces and wood stoves, no ventless heaters or fireplaces, and no open-combustion appliances or heaters connected to the living space. This helps to keep you from killing your clients.9. Basic ventilation. Hire an HVAC contractor who knows his stuff or buy the ASHRAE 62.2 standard, read it and follow it. It’s not that difficult.10. Manual D duct design. Although this is a code requirement, it’s often neglected. Use the same knowledgeable HVAC contractor, or better yet, hire an independent consultant to design and size the system and then put it out for pricing. Then make sure they do what it says.11. Radon vents in zone 1. If your building is in a radon hazard area, you have to put the vent system in under the slab or in the crawl space. If you forget, you are in for an expensive surprise at the end of the job.12. No HVAC in the Garage. Keep the furnace and ducts out of the garage; see Combustion Venting above about not killing your clients.13. Operations training. You have to either spend an hour with your client or have an outline for an hour of training and have a written owner’s manual. That’s a good business policy, and the hour you spend with them will probably save you lots of phone calls in the future. For Experts Only – The Tough Credits1. Design Charrette. It’s always a good idea to have a design charrette, but not always feasible on single-family projects, although the time and money spent to hold one will probably pay off in both first cost and operating energy savings. If you are doing a large development or a multifamily building, one charrette can cover all the homes and almost guarantees you a better project, money and energy savings, and a point on your score.2. Design for Solar Orientation. The Anazasi did it almost a thousand years ago; I think we should be able to figure out how to design with sun in mind and pick up a point in the process. Why is this one so difficult?3. Efficient hot water distribution. To get the 2 points for this you have to be very careful about where you locate all your hot water fixtures — preferably they will be close together — and make sure that the plumbing is designed to keep wasted water at a minimum. This can be tough, but if you design with an efficient hot water system in mind, it can be done.4. Backdraft potential test. If you install unsealed fireplaces and wood stoves (not a good idea in a high performance house), you can get an extra point if you have a (very complicated) third-party test performed proving that it can’t backdraft. If you have a monster range hood without makeup air, don’t even bother with this one — it won’t pass.5. Test ventilation and duct systems. If you have a third-party rater test the required whole-house, bathroom, and kitchen vent systems, and if the rater confirms that they meet ASHRAE 62.2 requirements, you can pick up 2 points. You can pick up another point for testing and balancing the HVAC duct system and confirming that it meets the designed flows at each register. Keep in mind that these tests aren’t inexpensive, and if they don’t come out right, you don’t get the points.center_img *Are We Really Cheating?Well, no, we’re not cheating to get certification. But LEED is a complex animal, takes some effort to figure out, and requires somewhere between a little and whole lot of extra time and energy to manage, depending on how organized your operation is.Larger contractors with administrative staff and architectural firms that are used to the documentation requirements of commercial projects tend to have an easier time keeping up with everything. Smaller single-family builders, particularly in the current economic climate, often struggling just to keep each job on track and on budget, have more trouble keeping up with the documentation and required field operations to meet certification.LEED is not for the faint of heart or those with weak administrative skills. But it can help make a home better and give the project team some ammunition for future marketing when followed through to completion. Now that all of you who read the first column in this series think you are experts at working the LEED for Homes system, I will show you some of the points that are much harder to qualify for along with a few that are pretty easy, but they are not very obvious and you have to know about them to take them.last_img read more

Oh, The Irony: National Vulnerablity Database Taken Down By Malware

first_imgAs if we needed more evidence that the hackers are winning, here is this: the National Vulnerability Database hosted by the National Institute of Standards and Technology has been stricken with malware and taken offline.The NVD is a comprehensive database that integrates all of the United State’s government publicly available vulnerability resources. It is a resource to many security firms and security officers at enterprises for tracking day-to-day exploits that malicious hackers could use to breach secure systems.In an email to security researcher Kim Halavakoski of Finland, NIST said that it had found multiple instances of malware on its public facing NVD websites and took the appropriate action to take the websites offline. “The National Vulnerability Database public-facing Web site and several other NIST-hosted Web sites are currently unavailable due to discovery of malware on two NIST Web servers,” wrote Gail Porter from the NIST Public Inquiries Office, according to a Google+ post by Halavakoski as reported by The Register.Visits to the NVD website confirm that it is indeed unavailable as of 9:00 a.m. EST, March 14.  The email from Porter to Halavokoski states that NIST’s firewall detected suspicious activity on Friday, March 8 and took steps to block the traffic from reaching the Internet. The malware on the NIST servers was traced to a software vulnerability. NIST said that there was no evidence its websites or the NVD contained or delivered any malware to users. “NIST continually works to maintain the integrity of its IT infrastructure and acts to limit the impact of malware on its systems. We regret the impact this has had on our services,” Porter wrote.Nowadays, everything is a target. That goes for the public facing websites and servers of prominent government agencies such as the NIST and CIA. When it comes to the backbone of government systems (non-public facing servers), those are much harder to crack. That is why we see more distributed denial of service (DDoS) attacks on prominent websites than actual breaches. Much of this DDoS activity came from groups like Anonymous and LulzSec, but the global black hat hacker community has been stepping up its efforts in past years to actually breach internal servers. We have seen this through more advanced spear phishing techniques and the alleged hacker wing of the People’s Liberation Army of China. The NIST NVD site makes for an easy target. It is relied upon by many different groups and has a necessary public-facing websites that is, by basic Internet Protocol, vulnerable. NIST played the breach by the book and took the site down.  3 Areas of Your Business that Need Tech Now Massive Non-Desk Workforce is an Opportunity fo… Tags:#Government#hackers#security Cognitive Automation is the Immediate Future of… IT + Project Management: A Love Affair dan rowinski Related Posts last_img read more

Djokovic Grand Slam run ends at French Open vs Thiem

first_imgEthel Booba twits Mocha over 2 toilets in one cubicle at SEA Games venue It will be the fourth straight day that Thiem is in action because of postponements, whereas Nadal will be well-rested, having played his quarterfinal Tuesday and his semifinal Friday, when he beat Roger Federer 6-3, 6-4, 6-2. Beating Thiem again would allow Nadal to raise his Grand Slam total to 18 titles, moving him with two of Federer’s record for a man.In the women’s final, which started 1½ hours late Saturday because it followed Thiem-Djokovic at Court Philippe Chatrier, No. 8 seed Ash Barty of Australia won her first major title by beating unseeded 19-year-old Marketa Vondrousova of the Czech Republic 6-1, 6-3.On Friday, Thiem had just broken Djokovic to go up a break at 3-1 in the third set when their match was suspended because of a shower. They resumed 18½ hours later, in dry, breezy conditions. The wind that was so fierce Friday — spreading loose, rust-colored clay dust from the court surface all over the place, making for something that seemed like a sandstorm — was much more manageable Saturday. It rippled players’ shirts but did not cause havoc with serve tosses and shots the way it had the evening prior.“One of the worst conditions I have ever been part of,” Djokovic said about Friday. “That’s all I can tell you.”Repeatedly, they engaged in long and entertaining points that lasted 10 shots, 20 shots or more. They used anticipation and enviable court coverage to track down each other’s shots. They walloped the ball from all angles.The very longest of these exchanges tended to go Djokovic’s way: He won 37 of 61 points (61 of nine or more strokes.For whatever reason, Djokovic often felt compelled to try to shorten points often, hardly his usual strategy. So that led to this key statistic: He won only 35 of 71 points when he went to the net. Thiem, meanwhile, took 18 of 20 on his more judicious forays forward.Serving at 15-all while down 6-5 in the third set, Djokovic was agitated by a warning from chair umpire Jaume Campistol for letting the serve clock expire. Djokovic wouldn’t let it go, complaining so much he was called for unsportsmanlike conduct.The lack of focus drifted into his play, too, including a serve-and-volley attempt that handed that set to Thiem.After forcing a fifth, Djokovic faltered again, getting broken to trail 3-1 when he missed a volley, before Thiem held for 4-1, shortly before rain came.

Scouting for Sports talent to come to hotspot communities

first_img Related Items: Facebook Twitter Google+LinkedInPinterestWhatsAppBahamas, June 22nd 2017: Newly Appointed Youth, Sports and Cultural Development Minister, Michael Pintard says government will embark on a vigorous programme to recruit sporting talent from hot spot areas across the country.Speaking during his contribution to the fiscal package, the Minister says it will go to these communities, and not ‘traditional venues’. He says young people can expect them to be in communities where they live, through the mediums that they listen to, and not the ones that we presume that they are listening to or watching”.He added that concentration will be given to “building our feeder system” with focus on training and supporting emerging athletes, budding cultural practitioners and young people”, in other words,  “who may otherwise fall through the cracks or under-achieve if not guided and supported”.Minister Pintard is also promising to pursue finances and other resources nationally and internationally, while it will amend legislation, policies and programs to facilitate the drive. Pintard says his government will look into providing “world-class physical infrastructure for youth, sports and cultural development”.The effort will also demand that everyone is working “closely with other government agencies and ministries to minimize scheduling conflicts and to reduce duplication of efforts and resources”.Minister Pintard noted his Ministry will enter this fiscal year with an aim at being more outreach-minded in staging events, holding discussions and targeting Bahamians. #MagneticMediaNews#MichaelPintardToBringSportsToHotSpotCommunitiescenter_img Facebook Twitter Google+LinkedInPinterestWhatsApplast_img read more

BAHAMAS Statement from the Ministry of Social Services with Respect to Disabilities

first_img Related Items: Facebook Twitter Google+LinkedInPinterestWhatsApp#Bahamas, January 23, 2018 – Nassau – The Persons with Disabilities (Equal Opportunities), Act 2014 and its provisions are largely monitored by the Disabilities Commission, a Board appointed by the Cabinet under the Ministry of Social Services and Urban Development.The Commission recognizes that the date for enforcement with respect to the Disabilities Act was 31st December, 2017.  The public and all persons and businesses affected have been given two (2) years to become compliant with the provisions of the Act, from 1st January, 2016 to 31st December, 2017.  The implementation of such measures require financial adjustments, in addition to engineering and structural arrangements.Given that backdrop, it is the Commission’s considered position that a widespread extension is not preferable.  However, there has been requests for extensions which have been responded to on a case-by-case basis.While not all government or private buildings are compliant to date, we have noticed that private businesses and government building operators have been making considerable efforts to ensure their buildings are accessible as required by law.  The current challenges include the ability of proprietors to make the necessary investments in the physical upgrade of premises, in addition to the difficulty with older building structures challenged with spacing and otherwise to make the necessary accommodations.The Commission on behalf of the Ministry will facilitate the enforcement of the Act for and on behalf of members of the disabled community.  We will continue to work with all stakeholders to ensure the disabled are enabled to obtain equal access and opportunities to function effectively in the society.
