NASA-Ames Research Center has produced an online simulation game called AstroVenture that allows kids to try to design a habitable planet. After they pick half a dozen parameters, the game tells them whether humans could live there or not.This is a cute feature that, with caveats, could be useful for parents and teachers. The main problem is that it is too simplistic. The planet-construction dialog asks what kind of star you want to put your planet around, how close to the star, how big it is, whether it has water and a few other things. These are fine and good, but not enough. It doesn’t discuss many other factors that could be show-stoppers: crustal composition, type of atmosphere, place in the galaxy, eccentricity of the orbit, size and distance of moon, and much more. Still, kids may be surprised to find how few of their choices actually work. Of course, the Astrobiology folks behind AstroVenture want kids to learn early how to speculate about life in outer space. They want to help kids exercise the power of imagination and speculation, since these are prerequisites for Darwin Party membership later. All that aside, learning that only a small subset of possible planets are even in the ballpark for life is a worthwhile lesson. For junior high and older, use this in conjunction with the film The Privileged Planet.(Visited 8 times, 1 visits today)FacebookTwitterPinterestSave分享0
5 December 2007Unlike most destinations where tourists have to buy bottled water, South Africa’s tap water is of high quality and compares favourably with that of leading industrialised nations, leaving visitors with extra money to spend elsewhere.The Department of Water Affairs and Forestry’s technical regulation director, Leonardo Manus, told BuaNews this week that according to guidelines issued by the World Health Organisation, South Africa compared favourable with countries such as Canada, which is a world leader in managing the quality of tap water.“We we have great confidence in the quality of the tap water reticulated in our cities and bigger towns,” Manus said.Manus noted, however, that more work needed to be done before the department could claim the same level of confidence in the rural areas and smaller towns in the country.“This is due to the fact that some of our communities are not connected to systems that provide treated water, due to some historic disadvantages and a lack of technical capacity at smaller municipalities,” he said.He said the department had taken various steps to ensure that a “preventative culture” was adopted in the management of drinking water quality.“As part of the 2010 World Cup preparations, the department is joining hands with the host cities and towns to get water safety and security plans in place to ensure that the municipalities are prepared for the occurrence of drinking water quality failures,” Manus said, adding that this would also help in putting early warning mechanisms in place.Sue Freese of the Water Institute for Southern Africa said the reason for the country’s clean water was because of the existing infrastructure, which was properly maintained.“South Africa has a good maintenance programme in place to avoid decay, and the Department of Water Affairs and Forestry is helpful in implementing drinking water qualification regulations to water authorities,” Freese said.Source: BuaNews
Think desktop email is dead? Not so says the latest entrant to this field, San Francisco-based startup Postbox, who is today revealing the final release of their desktop email application based on Mozilla technology. Originally launched into beta a year ago, Postbox has a heavy focus on search and organization with a primary goal of addressing email users’ information overload issues. Like Mozilla’s own Thunderbird email application, Postbox exists only as downloadable software. However, unlike other desktop programs, Postbox natively integrates web services into its interface, including Facebook, Twitter, and FriendFeed.When you first get started with Postbox, you’re promoted to select from a list of web-based email accounts including Gmail, AOL, Windows Live Hotmail, and Yahoo! mail. If you’re using the app for anything else, you can select “other email account” instead. You’re able to import RSS feeds and Newsgroup accounts, too. Top Reasons to Go With Managed WordPress Hosting To-Do’s: For getting things done, Postbox lets you turn email messages into “to do” items which pushes them to the top of your inbox where they stayed pinned until complete. Inspector Pane: When viewing an email message, the so-called “Inspector Pane” on the right summarizes the content detected within that email conversation including information about the sender, attachments, images, links, addresses, etc. What’s interesting is that the sender’s profile picture can actually be retrieved from Facebook or Twitter if you’ve linked your accounts from the Web Services menu (under Tools). Topics: Similar to Gmail’s “labels,” Postbox uses “topics” for organizing email, a system that helps you stay on top of your current projects. And as with Gmail, messages can be flagged with multiple topics. This can be done either after you receive them or as you compose an email. Postbox will also automatically tag future emails within a thread with the same topic.Compose Sidebar: Also in the Compose window is a sidebar which provides easy access to images, attachments, links, contacts, and signatures stored elsewhere in your email. Click on any of these icons and a search box appears allowing you to quickly retrieve items. A Web Developer’s New Best Friend is the AI Wai… Why Tech Companies Need Simpler Terms of Servic… Tags:#Product Reviews#web Related Posts sarah perez Postbox FeaturesSearch: Once configured, Postbox looks very much like any other email program you’ve used in the past – this is no radical redesign like Google Wave plans on being. There’s a message list, preview pane, folder lists, favorite folders, etc. However, the killer features in this application don’t have anything to do with its design. Instead, what makes Postbox so appealing to power emailers are its search and organization features. The application can help you find anything in your email whether a contact, an address, a link, a picture, an attachment, or even just a snippet of text. Searches appear in Postbox’s tabbed interface where visual results – like photo thumbnails, for example – make finding the right result easy. Extensions: Although Postbox doesn’t include a calendar of its own, the Lightning add-on, one of several supported extensions lets you view your calendar as a separate tab in Postbox. It provides access to your Gmail calendar, too. A Lot to LikeEven though many email users are happy with their web-based solution of choice, there’s a lot to like about Postbox’s desktop app. For example, we especially like the ability to post from our email directly to Facebook, Twitter, and FriendFeed. And what we wouldn’t give for visual search like this in Gmail! Postbox’s search features are robust yet simple to use and the handy “Inspector Pane” is a useful tool that could easily become an essential component to your email workflow. For these reasons and more, it’s no surprise that this application made our list of favorites earlier this year. (See: Still Shiny: 23 Apps We’re Using One Month Later). With the public release of version 1.0 of this application, the company isn’t introducing any major upgrades, but that shouldn’t stop you from giving it a look if you’re interested in desktop email clients. Postbox is available as a free trial, but sells for $39.95 if you decide to purchase. 8 Best WordPress Hosting Solutions on the Market

As Greg Maddux, Tom Glavine and Frank Thomas celebrated their inductions in Cooperstown this weekend, the Baseball Hall of Fame announced a change that will make it harder for others to join them. Instead of having 15 years of eligibility for consideration by the Baseball Writers’ Association of America (BBWAA), players will now be limited to 10.1A player becomes eligible five years after retirement. If he doesn’t receive at least 5 percent of the votes the first year, he’s excluded from future ballots.One theory is that the change is designed to exclude players like Barry Bonds and Roger Clemens, who are known or suspected to have used performance-enhancing drugs.2Retired players such as Alan Trammell who have already appeared on at least 10 ballots will be exempt from the rule. But Bonds and Clemens, who joined the ballot in 2013, won’t be. But an attempt to target Bonds and Clemens could produce collateral damage. Players such as Curt Schilling, Edgar Martinez, Mike Mussina and Larry Walker — who are not strongly associated with PED use — could also be less likely to get in.Take the case of Mussina, who received 20 percent of the vote on this year’s ballot, his first year of eligibility. He might seem like a hopeless case — players need 75 percent of the vote to be elected to the Hall of Fame. But players generally gain ground the longer they remain on the ballot. Sometimes they need the full 15 years to get there.Consider other players who received somewhere between 15 and 25 percent of the vote in their first eligible season. There were 16 such players between 1966, when the Hall of Fame began holding elections every year instead of every other one, and 2000, the most recent class of players to have exhausted their 15-year eligibility window:Two of these players, Don Drysdale and Billy Williams, gained ground quickly enough to be elected to the Hall of Fame within their first 10 eligible seasons.Another three — Bruce Sutter, Bert Blyleven and Duke Snider — were elected by the BBWAA at some point between their 11th and 15th eligible seasons.One player, Red Schoendienst, was elected later by the Veterans Committee.The 10 remaining players — Gil Hodges, Jack Morris, Roger Maris, Tommy John, Mickey Lolich, Jim Kaat, Dale Murphy, Dave Parker, Thurmon Munson and Tony Oliva — have not yet made the Hall of Fame, though some are plausible candidates for election by the Veterans Committee at a later date.So by a quick-and-dirty rendering, Mussina’s chances of getting elected to the Hall of Fame by the BBWAA have been sliced from 5 in 16 (representing the five players who made it within 15 seasons) to 2 in 16 (only Drysdale and Williams made it within their first 10 seasons). He might also have some chances with the Veterans Committee. But the Veterans Committee has been stingy about electing players in recent years. The point is that players like Mussina need all the chances they can get.We can formalize this analysis by running a set of logistic regressions that estimate a player’s likelihood of eventually making the Hall of Fame based on his performance in his first year on the BBWAA ballot. First, I ran a regression to consider whether players were selected by the BBWAA within 15 seasons.3As in the Mussina example, this regression considered all players who first appeared on the ballot between 1966 and 2000. I excluded players who were elected in their first year, or who received less than 5 percent of the vote in the first year, as these players have been automatically dropped from the ballot since 1985. Then I ran another regression to evaluate whether players made it within their first 10 eligible seasons. (Among players who first appeared on the ballot in 1966 or later, those who were elected by the BBWAA somewhere between their 11th and 15th seasons were Snider, Sutter, Blyleven and Jim Rice.)4For this regression, I included players who first appeared on the ballot from 2001 through 2005, in addition to those between 1966 and 2000, since they’ve had 10 years to be elected. Finally, I considered whether players made the Hall of Fame at all — whether through the BBWAA or the Veterans Committee.5In this case, I included all players who first appeared on the ballot from 1966 through 1995 — players who began appearing on the ballot after 1995 have not yet been eligible for consideration by the Veterans Committee, as best I can tell. For this regression only, I also included players who received less than 5 percent of the vote in their first year on the ballot — a few of these players (Richie Ashburn, Larry Doby and Ron Santo) were eventually elected by the Veterans Committee. The results are represented in the chart below.To read the chart, scan across until you find a player’s vote share in his first year of eligibility — then scan up to see where the various curves intersect it. For instance, for a player like Mussina who got 20 percent of the vote in his first year:There is a 10 percent chance he gets elected within his first 10 years of BBWAA eligibility, according to the regression analysis. (This is the yellow curve.)There is a 23 percent chance he gets elected within the 15-year eligibility window. (The red curve.)There is a 34 percent chance he gets elected by either the BBWAA or eventually by the Veterans Committee. (The blue curve.)These answers aren’t too far from the quick-and-dirty numbers that I came up with before. They suggest that Mussina is an underdog to make the Hall of Fame — but more of an underdog now that he’ll have only 10 years of eligibility to do so.What about a player — such as Bonds — who got 36 percent of the vote in his first season of eligibility?He’d have a 53 percent chance of being elected by the BBWAA within 10 years.His odds of being elected within 15 years are higher — 69 percent.He has an 89 percent chance of being elected by some means — either the BBWAA or the Veterans Committee.So a player like this will also see his chances of being elected by the BBWAA decrease with the rule change. But he has a much better backstop: The Veterans Committee has usually elected players like this even when they were bypassed by the writers. That hasn’t been true for players like Mussina.Of course, Bonds and Clemens are no ordinary cases — and this method may not do a very good job of describing their chances. There are a couple of other objections that we need to consider first, however.One is that the change in rules could affect voter behavior. Players sometimes receive a boost in their vote share in their 15th and final year of eligibility. Now, knowing that it’s their last chance, the writers could rally around a player in his 10th year instead.That might protect a few players — Snider, for instance, got 71 percent of the vote in his 10th year of eligibility and might have made it then if a few more writers thought it was their last opportunity to elect him. But Blyleven had only 48 percent of the vote in his 10th year. His case, which was pushed by stat-savvy baseball fans for years, needed some extra time to marinate.Another consideration is that rotating players off the ballot sooner could clear slots for more recently retired players. BBWAA voters are limited to naming 10 players on their ballots. A few of them might have run out of room for Mussina this year, for instance, because they were reserving space for Alan Trammell, Jack Morris, or other players between their 11th and 15th years of eligibility.Indeed, this could be of some help to players like Mussina. But there would be a more direct means of providing relief — by liberalizing or eliminating the 10-player limit. Players from the 1980s, 1990s and 2000s are badly underrepresented in the Hall of Fame relative to players who had the good fortune to be born earlier.The rule change, in other words, seems designed to make the Hall of Fame more exclusive, not less so. But how might it affect Bonds and Clemens in particular?As I mentioned, they aren’t ordinary cases. For a player like Mussina, a large fraction of the BBWAA electorate might be thought of as “swing voters” — they could live with him in the Hall of Fame or without. Given how strong feelings are on the issue of performance-enhancing drugs, the choice is likely to be much more binary for Bonds and Clemens. For that reason, their vote shares might not increase as much in future seasons. (Another PED user, Mark McGwire, has been on the ballot for eight seasons and has seen his vote share decrease in almost every one.) Personally, I’d wager a fair amount of money against Bonds or Clemens ever being elected to the Hall of Fame by the writers, whether in 10 years or 15.Nevertheless, baseball’s hive mind could change its stance on PED use with the benefit of hindsight. It’s not that hard to conceive of alternate realities. NFL players who were suspended for PED use, like the former San Diego Chargers linebacker Shawne Merriman, barely seem to suffer any lasting damage to their reputations. (Merriman made the Pro Bowl in 2006, the same year he was suspended for four games.)One scenario could involve a known PED user who is otherwise a more sympathetic case than Bonds or Clemens making the Hall of Fame.6Or a player who is already in the Hall of Fame could disclose his PED use. For instance, Andy Pettitte, who admitted to using human growth hormone, is due to become eligible for the Hall of Fame in 2019. Pettitte’s case is not clear-cut on the statistical merits, but suppose he made it in 2023, his fifth year on the ballot. Under the old rules, Bonds and Clemens would have had a few years left on the ballot with that precedent in place. Now, they’ll already have exhausted their eligibility.Bonds and Clemens would still be eligible for consideration by the Veterans Committee. But whatever misgivings you might have about the BBWAA, the Veterans Committee has been far more problematic. Its rules are constantly changing, its process is not very transparent, and it has oscillated from being far too liberal to being very stingy about letting in players. Depending on the rules it drew up, the Hall of Fame could design a Veterans Committee that was relatively sympathetic to Bonds or Clemens — or firmly opposed to their election.Another theory is that the Hall of Fame doesn’t have strong feelings about Bonds and Clemens per se, but implemented the rule change in the hopes of putting the PED issue behind it sooner. It’s certainly not good advertising for Cooperstown when discussions are dominated every year by arguments over steroids.But these cases won’t go away anytime soon. Pettitte will become eligible in a few years — and a few years after him, Alex Rodriguez. Ryan Braun, another known PED user who could eventually build Hall of Fame statistics, is many years from retirement. In the meantime, players like Mussina could be caught in the crossfire.
