Imagine a coating that makes surfaces so slippery that nothing can stick to it, not even water or oily film. Inspired by the Nepenthes carnivorous plant whose slippery surfaces cause insects to slip into its planty belly, scientists have mimicked the properties to create the Slippery Liquid Infused Porous Surface Of course, they tout all sorts of useful functions like surfaces that never need to be cleaned again or ketchup bottles that can expel all of the condiment. But we all know where this substance is really going to end up … pranksters will coat hallways with it and the sex industry will market all kinds of new products. Thanks science!
Just the other day a friend of mine had a nice idea for a website, and like many descriptive names, the website was taken. It’s one of those fake looking websites with some ads links, and of course a page where you can submit an offer to buy the site for an excessive amount of money. Wouldn’t it be nice if we could use the legal system to deal with this?
This problem is quite prevalent. If you look into the domain name owner, you find out he owns about 1000 of these. These people provide no real service to the world, but merely try to anticipate a successful business and try to leech their own bit. Like with spam, a low hit percentage results in a profit. The domain name registration business itself even supports this peripheral industry. Note that Godaddy can help you buy scriptguru.com (link might be broken) for over $3k. Domaintools will help you buy scripthub.com (so despite their legal disclaimer, they do in fact list the domain for sale).
Riddle me this, basketball fans … what’s going on in the NBA?
I was always a baseball fan back in the day, but the 1994 strike pretty much ended my interest in professional sports. I didn’t really pay much attention to the football fiasco just a year or two ago but am now inundated by news reports of the NBA player strike. I finally broke down and read the article from CNN about disbanding some kind of player’s union and this little block caught my attention:
Getting caught on an open mic seems to be a right of passage for many US Presidents. Some prior incidents include Bush’s four minute rant on Hezbollah and other world leaders, Reagan joking about bombing the Soviets and Clinton berating an aide. Recently, at the G20 summit, President Obama joined the club while talking privately with French President Sarkozy. The conversation between them turned to Israeli Prime Minister Netanyahu where Sarkozy commented to the effect, “I can’t look at him [Netanyahu] anymore, he’s a liar.” Obama in turn replied, “You’re fed up with him, but I have to deal with him every day!” The anecdotes were ignored by the press after they agreed to remain mum until the French publication Arret Sur Images decided to run with it.
Quasars, actually quasi-stellar objects (QSO), are amongst the brightest space objects we know of. A quasar accretion disc is formed as the object circles a black hole and is slowly torn apart. According to the lead scientist in imaging one, “a quasar accretion disc has a typical size of a few light-days, or around 100 billion kilometres across, but they lie billions of light-years away. This means their apparent size when viewed from Earth is so small that we will probably never have a telescope powerful enough to see their structure directly.” NASA and ESA astronomers used the Hubble Space Telescope in conjunction with gravitational lensing (see the embedded QuickTime object below for an example) to produce a highly detailed image of a quasar and its accretion disc in order to accurately measure it’s size, shape and temperature. Using this technique, the team was able to determine (and image) a distant, faint object only 4-11 light days across.
The battle between iPhones, Blackberries and Androids continues. Apparently, the Android platform has a higher failure rate and runs carriers nearly $2 billion in repair costs. Unlike the competition whose platform is tightly controlled by their respective manufacturers, the Android is deployed by more than 25 OEMs each attempting to win the market. This, of course, leads OEMs to skimp on the product in order to undercut competing Androids in price and first-to-market features which tends to result in shoddier quality control.
To further hammer nails into Android, the new Siri feature found in the iPhone 4S is being hailed as an Android killer. Some estimate the application puts Google at a two year disadvantage behind Apple. Of course, it hasn’t taken long for the open source community to fire back with Zypr which also provides conversation driven questions and answers.
Most of us don’t give more thought to pancakes than how to wolf them down. But some French computer scientists [Laurent Bulteau, Guillaume Fertin and Irena Rusu] had nothing better to do than study them for some leisurely analysis on the sorting a permutation using prefix reversal algorithm. We can thank them for proving the problem isn’t just hard, it’s NP-Hard. In a nutshell, you’re supposed to sort a pancake stack into size order where your only operation is to insert a spatula and flip the entire upper pile over repeatedly. You can explode your brain with their mathematics reading the published paper.
The IAEA is slated to release a relatively damning report on the state of Iran’s nuclear development. This report will be releasing far more detail than IAEA has previously unveiled which will more or less directly charges the Iranians are developing nuclear weapons in contradiction to the country’s claims. Evidence varies and remains to be seen, but hints have alluded to the report detailing nuclear modelling and computer studies Iranians have performed that have nothing to do with energy production. Prior reports have not been so direct at calling out Iran’s programs as having such a slant towards weaponization.
This is just me being curious … why are various pots and pots not dishwasher safe? I’ve heard reasons given about Teflon coatings, special treatments, blah blah blah.
- If a pot can handle boiling water at 220 degrees, why can’t it handle regular 140-160 hot water?
- If the coatings can handle various food items and sauces stuck to it at high temperatures being mixed via physical contact of a spoon or spatula, why can’t it handle jets of water hitting it?
- If cleaning solutions and a sponge or pad can be used to physically clean off residual particles in a sink, why can’t it handle the cleaning chemicals in a dishwasher?
Last Thursday, Congress received their unclassified Foreign Economic Collection and Industrial Espionage report detailing activities from around the world (particularly in the cyber realm) and their impact on the US. The report directly insinuates the Chinese and Russians are the top offenders for building their economies on American research and technology, excerpted directly as “the nations of China and Russia, through their intelligence services and through their corporations, are attacking our research and development.” China’s Foreign Ministry spokesman rejected the claims stating, “online attacks are notable for spanning national borders and being anonymous. Identifying the attackers without carrying out a comprehensive investigation and making inferences about the attackers is both unprofessional and irresponsible. I hope the international community can abandon prejudice and work hard with China to maintain online security.”
This is downright cool. Some PhD students at the University of Illinois have created a system that allows for a computer to insert fake objects into standard photographs. This isn’t just some algorithm for layering and image insertion. Rather, the system allows for a 3D understanding of converging lines, light sources and objects. Once it has learned the environment, they can insert live, dynamic objects into the photo where it inherits light properties and can interact like pool balls on a table. (NOTE: Some browsers may not recognize the embedded Quicktime object in which case you’ll have to follow the link for the video demo)
Sounds like the Occupy Wall Street folks have a new ploy that’s catching on via Facebook … inciting bank runs. In the wake of Bank of America announcing $5 ATM fees, a Facebook user riled up followers about “Bank Transfer Day” to dump your existing accounts with large financial institutions for local banks and credit unions. Officially, Friday the 5th is marked for action with other movements sponsored by MoveOn.org and the Progressive Change Campaign Committee. While the number of pledged accounts to vanish is small (in the grand scheme of things), one begins to wonder where the threshold is crossed between banks taking notice and actual distress. After all, it wasn’t too long ago that revised Basel rules allowed banks to dip well below the previous fixed 10% liquidity requirement.
The Oakland, CA gathering of Occupy Wall Street protesters clashed with police before during a tear gassing incident. Now they’re clashing again after police attempted to move the protesters that gathered around the Port of Oakland effectively shutting it down where they aim to hurt business by impacting their supply lines. The effect has been twofold, both reinforcing to the protesters the link between business and government while at the same time hurting regular workers – part of the 99%. According to port officials, “continued missed shifts represent economic hardship for maritime workers, truckers and their families, as well as lost jobs and lost tax revenue for our region,” while harassed employees said, “I just want to go home … Why are they on top of my truck?” Meanwhile, occupiers state, “Our government is being bought by corporations. The middle class and lower class are being subjugated …. The port closure sends a message to the corporate world that we’re not going to sit by and take it anymore.”
It was just over two years ago that Google launched Sidewiki – a browser sidebar allowing anyone to comment about any site. I liked the idea at the time and immediately made a Sidewiki entry … on the page explaining Sidewiki:
Sidewiki^2 – What the what?! A Sidewiki post about the page explaining Sidewiki … that’s … that’s … just craziness.
I moved on and made more important entries … like this one on OmniNerd:
OmniNerd = Awesome (if you’re a nerd) – If you’re a nerd like me, then this is the site for you. Write about the nerdy stuff you’re into – and then discuss it with other nerds. (Okay, okay. I’m an admin on this site. Sue me.)
