JUNE 14, 2010 -- JUNE 27, 2010 IS WEAKER COPYRIGHT PROTECTION A BOON FOR SOCIETY?
A lot of the misery the industry is feeling is its own fault.. Read the article ARS TECHNICA/File sharing has weakened copyright and hepled society. <> Breaking laws is never a good thing, except to the extent that it's an indication that the laws themselves are bad, unjust, or impractical. IMO, we should look at the results of this paper as telling us that the framing of the discussion provided by large copyright holders (piracy is bad, piracy is killing us, piracy must be stopped, etc.) is extremely problematic. Casting this as a moral issue (amoral thieves and law-breakers versus hard-working rightsholders), or as an issue of law and justice (if you disagree, don't break the law, change it) ignores crucial features of the situation. You pointed out, quite correctly that this is a complicated issue, but the fact is that those arguing for more rights for rightsholders are over-simplifying at least as much, and at least as disingenuously, as anyone else.

ONCE UPON A VAST AND ANCIENT OCEAN OF MARS
Mars lost it's oceans because it's so small. That sounds obvious but it's a bit more subtle than it seems. Mars is slightly smaller than the size needed for gravitational pressure to allow molten iron to exist at the centre. If it was slightly larger, we are talking 10% or so then it would. Earths molten iron centre creates our magnetic field, which is quite big considering the size of earth, as it is largley iron and is rotating at a fairly high rate. The magnetic field blocks solar radiation and the solar wind. Because Mars doesn't have a molten iron centre it's magnetic field is very small so the solar winds and radiation can strip the upper atmosphere away.Over millions of years this would gradually reduce the density of the atmosphere allow the water to evaporate and then be removed. The lack of water on the planet means CO2 levels would increase leaving the planet we see now, largley dry, low density atmosphere and a very high level of CO2 (about 65% I think of hand). Read the article DAILY MAIL/The red plains of Mars were once covered by a vast ocean <> Maybe all the asteroids in the belt beyond Mars were once a planet with an advance race of beings that destroyed themselves. Then a chunk of that planet crashed into Mars, causing Mars to lose its oceans. Then those beings migrated to Earth to start the self destruction process all over again.

In 1938 University of Oregon archaeologist, Louis Cressman, found several sandals in a cave near Fort Rock in the Christmas Valley, in Oregon. The oldest one has been carbon dated to 9,188 +/-480 B.P. As the story of this Armenian shoe find is trickling around the world, it seems that history has forgotten Cressman's find. The sandal is on display in their museum on campus.

JUNE 7, 2010 -- JUNE 13, 2010
Honestly, I find it amazing that people still haven't learned their lesson when it comes to Apple. Every time Apple releases something, the nay-sayers start telling how their favourite device has had the same features for years already. And this happens every single time. And those people never learn the one simple fact: it's not about what you can do with the device, it's how you do it. Read the article ARS TECHNICA/iPhone 4 unveiled <> Those of you who think apple is making a "mistake" by failing to make the iphone available through networks other than just AT&T have conveniently forgotten the way that cell phone service tends to work in the U.S. The carrier normally dominates the customer relationship and has complete control over the equipment. For many reasons, this would not have been suitable for the Apple and the iPhone. Apple managed to alter this hegemony in its relationship with AT&T, but only by offering unusual consideration -- a multi-year exclusive relationship. Read the article WALL STREET JOUNRAL/Apple unveils iPhone 4 <> I am on my computers all day. My home office and remote sites have WiFi. I can’t use the phone when I’m driving anyway. I know where I’m going so don’t need the GPS. I make, oh maybe three to five calls a week. I have a really great Canon camera we got last year. There’s so many reasons to not get an iPhone. But you know, that camera is sweet. And the prospect of having Skype available so my aged family members could call me anytime at no cost is appealing. And supposedly the data plans have improved in the last year. And being able to check weather on the road would be nice. And…well… I’m tired of being the odd man out. OK, fine, I’ve said it. There is a degree of feeling like the poor kid with K-Mart shoes on the playground when everyone else is wearing Nike. Everyone, literally EVERYONE I work with has a smart phone as do most of my friends and relatives. Half iPhones and the rest a mix of BlackBerries and Android phones. Heck my 80 YEAR OLD MOTHER has a phone that does more than mine. My phone doesn’t even have a camera, or voicemail, or IM. It’s the bottom end, cheapest, talk only and do nothing else whatsoever phone. It’s getting embarrassing for me, an IT Guru, to have such a crappy phone. Sure it does what I ask it to. I keep wondering though if I’d use my phone more if it could do more. Heck, for the first time I might even start to LIKE my phone. Well, 6 months till my contract is up. Then I’ll decide.

MAY 31, 2010 -- JUNE 6, 2010 WHAT IS THE INTERNET DOING TO OUR MINDS? It’s not the internet that’s the problem. It’s individuals that want to be butterflies instead of bees. They think it’s the superficial, rather than the profound, that is important. It’s perfectly possible for any sensible person to use the internet in a productive way. What is really the problem is television. It has taught many young people that if what you are watching doesn’t titillate you within ten seconds change the channel. Twitter follows in this path. If you can say it in one sentence its not important. Twitter may use the internet, but it ignores what is really important about the internet, the depth of information that can be accessed if you’re not perverted by the TV generation. Many of us pre-TV old timers don’t have a problem doing this. Turn off the TV and get off Twitter. Don’t be a Facebook or email junkie. Then you will be able to take advantage of what the internet really has to offer. Blaming the internet is a classic case of blaming the messenger. Read the article REUTERS/Book asks: Is the Internet ruining our minds? <> Having worked on computers ever since 8 a.m. on 2 Feb 1982 (the day I started my apprenticeship), my observation on the internet is that it has destroyed value. It has destroyed the value of information and destroyed the value and the value chain of goods and services to a greater than lesser degree (yes there are possibly a greater number of hobby sized businesses, but they are making comparative pennies).
Read the article REUTERS/Book asks: Is the Internet ruining our minds? <> If you think that the internet is taking away some mental skills then you are probably one the people who will be left behind and have yet to evolve which would make sense for someone who seems so lost. With all the information that is “overwhelming,” it can be said that as we get better at dissecting and consuming we can leave the rest to game theory what will happen next, best practices will be adopted and erroneous information will be filtered out. I mean if you look at what we do in our daily lives there are a few things that get past us and answers that are rarely left unanswered, collaboration is happening on grander scales and to connect to someone personally is no longer needed, we can connect with the world without a physical connection. Today you meet a group a people that barely understand you, tomorrow you meet a world of people that think just like you. Read the article REUTERS/Book asks: Is the Internet ruining our minds?
MS. ROSENBERG SUES GOOGLE MAPS FOR BAD WALKING DIRECTIONS This is a frivolous lawsuit. That being said, I was horrified when I invited several people from the South Bay to my place in the Outer Richmond, and learned that Google maps had told them to turn left from Crossover onto Fulton. There are many clearly marked "no left turn" signs at that intersection, but that explains the many people I see there every weekend determined to turn left. Read the article SAN FRANCISCO CHRONICLE /Lawyer of suing woman: Google maps "created a trap" <> Google and similar map websites have a disclaimer that the directions they provide are only "guidelines" and the user needs to check other sources.

RIDING THE WAVE AT MACH 5 WITH X51 SCRAMJET
Scramjet tech is pretty cool, but so far I'm not seeing the practical applications. The engines only work at high supersonic speeds, so developing an aircraft that can take off from a runway, accelerate to hypersonic speeds, fly for an extended period at those speeds, then slow down and land is a long, long way off. The comparison of the leap into scramjet engines as being just like the change from piston driven propellers to turbojets post WWII is a bit off. It didn't take much to adapt common airframe shapes and materials to jet propulsion. With hypersonic scramjets we're on the bleeding edge of materials science and aeronautical science. I worry about these aircraft being left to splash into the ocean and not be recovered. Who wants to take the bet that the Chinese were watching this test and sent in a boat to pick up the pieces for study and reverse engineering? Read the article SPACE.COM/Air Force's X51 scramjet sets record for longest hypersonic flight
<> I can't see turbojet -> scramjet being a particularly pleasant (or survivable) experience for a squidgy human. Then there's the whole issue of materials science - throw away experiments (as impressive as this one is) are one thing, having a boat that can fly mach 5+, be refuelled and turn around for another sortie without bits (like engines, wings etc) falling off is another. The friction on that thing must be crazy. I know it's not quite in the region of atmospheric re-entry, but it ain't *that* far off. I don't imagine ejection would be that healthy an option either! Hope they (as in America) don't think that using it as a cruise/Exocet type missile is a good idea tho. You can imagine the news story already - "an American missile today destroyed a terrorist training camp killing 80 combatants. On its path to its target its shockwave destroyed 14 schools and 3 market towns killing 1500 civilians. Officials said they were 'looking into the matter'".
