We really need an analysis done and report made to the public security community. This is a unique chance to discover what are the real vulnerabilities to the mass of computing power on which criminals prey.
A federal or state level court needs to authorize the researchers to do such an analysis. Even a single state would be enough, if the zombie IPs can be reliably mapped to that state. I would envision the analysis to include:
- Make a full study of many individual zombie PCs: What antivirus, firewall, OS, applications, etc. are installed, including version numbers and a fingerprint (to identify whether they are super-vulnerable copies from warez sites, infected OEMs, etc.). - Monitor usage of a small number of PCs to identify what user habits lead to zombification, based on the theory that these PCs will become zombies of another botnet soon probably. What should be monitored, and for how long? - Contact (with law enforcement assistance) a small number of individual users to interview them. Publish anonymized interviews for representative cases so the public can better learn what constitutes dangerous habits. - Report anonymized individual representative cases, trends and statistics.
Discuss whether the defanged botnet should be used to destroy other botnets. Too much discussion would alert the other net owners. People could opt in based on a message sent to infected PCs, if the authorities support it, but unless those bots are hardened they might open the owners to retaliatory attacks.
At least, let's find out if antivirus really doesn't work, what habits led to botnet creation, and how can we alert zombie owners so they adopt more secure practices.
P.P.S. Also I would recommend extending the wireless network to the seminar room. It would allow a computer assisted meeting (CAM) where audience could ask questions instead of just 1 or 2 people and 1 mic then time's up, people could pose questions to that day/time's seminar blog or to a CAM system and a moderator could pick good questions, or the speakers could also type answers, or follow up later. It would be very cool. CAM used to be too expensive for large numbers of people (I once propose one for 2000 but clients are too expensive) but now everyone has a laptop or a cellphone for texting. It can be done now. It would be nice if you could provide multiple projectors too. Speakers will want to run their applications they built and maybe need higher resolution, or show a closeup of the speaker while he's talking in another projector.
P.S. If you go to the ICC page you can see their Metaverse / Hive project, an open video archive. I think some links are Japanese but they have recordings of seminars too. I too dislike the disc changer idea but I don't know how much money you all have. If possible do as some other posters say, bring much high bandwidth cabling around and also put in clients with much horsepower. I was thinking of quad Mac Pro with large screen at each location. The huge fast SAN someone mentioned also sounds scrumptious. If you can't afford it all now just block out purchases in the future maybe. But don't get crappy old stuff.
Anyway on the Hive top page you see it is bilingual, and there is an announcement about licensing, and you can say click on an "ICC artist talk" like this one for Knowbotic Research who are very cool. There is info about the artists and their homepage, plus a link to the exhibit page from when their exhibit was in the museum (yes you have to archive all of that too, and probably hire an admin to manage updates, a student will do). There is a streaming link. And (whoa I just discovered this and will be diving into the hive from now on I assure you) a DOWNLOAD LINK! Where you can get a zip file of the talk which is perfect. The library makes it CC licensed and open to the Net which is also perfect. The file is a WMA at 720x480 and 44Khz audio, perhaps lower quality than you will have in the future. Check it out, the beginning of the file is Japanese but advance a bit and it becomes English. It would be nice to have an editing studio so you can add other language tracks in the future (or just subtitles, that would be easier in a separate file). In this video file you can see how they are having a panel discussion, and the speaker plugs their laptop into the projector. Figure you will have very high-end machines on stage potentially, or connecting to/from the net. And provide a HD camera for the view of the stage. Hope this helps, the ICC really built just what you want and it looks like they have kept it updated technologically. They even have a metaverse project. You may need to host virtual worlds in the future, I guess that is pretty likely right now. Many artworks are in 3d virtual spaces or in a large web of webpages, like i love bees and david blair's wax web (which also included video and was so slow over the web of about 95 or so.). Consider Blair was IIRC the first artist to plug a VCR into the net and stream it, you are definitely going to be having a taxed infrastructure and all you can do is make it delightful to be there and work with boosting it. A big SAN is probably something you need.
One thing I liked from something someone mentioned, the video jog dial (not really a jog, you spin it with your finger in the hole to advance or rewind video). That client looked like crap though. I'd consider how do people use the system and maybe for each station also consider (it's not that expensive) some usb add-ons like a tiny side screen for navigation (if you are full screen video), a 3D round shuttle like this or maybe this, and a cheapo printer. I have no idea if 3d printers will get cheap one day (well yes there's a nice tabletop one I think) but just something now that people can print out a screen shot or notes. Of course best if they can just mail to themselves maybe, then no need to stock paper/ink.
I know one media art museum that has a video library, state of the art 10 years ago and still useful but I could make some recommendations. I am talking about the NTT ICC (Intercommunication Center) and I maybe remember it in a distorted fashion, and it was reduced in size too, but it is at the New National Opera at Opera City, Hatsudai, Tokyo. I haven't been there lately but check it out at http://www.ntticc.or.jp/index_e.html
1. The museum has a big, very expensive SGI machine (20 cpus? I forget) used for graphics intensive installations. I believe it was used on a CAVE, a gesture recognition articifical life generating installation, an interactive 3d sculpting program, etc. Nowadays I would expect you just provide a rack of machines like Mac OS X servers or the new genre of "deskside supercomputer" i.e. many graphics boards, many (up to 80) cpus, etc. If you are going to provide resources for installations. Also a studio where artists can come work to build the final stage of their installations, would be awesome (video and graphics studio would be cool).
2. As for the video library the key is to have the content. The one I knew was a bit hard to navigate but allowed you to view IIRC interviews with artists and video works by video artists. Maybe also video documents of performance type works I forget. The headphones I think were good maybe. Screens etc. sucked. Nowadays, people have powerful laptops and they write their notes on them. Also many artworks may be created with client-side animations (like with Processing). So I would provide at least some high-end clients, and also a wireless network for people to connect their own machines. It would be nice if there were areas where one could use projection for a piece that needs to be seen big (or that requires the user to stand in front and interact) or a little room with a superior sound system, there are lots of kinds of art. Thin client? I read it as a piece of junk that is substandard even before you install it, only able to view old-fashioned NTSC. We're in the days of HD terrestrial broadcast, blue-ray and high def digital cinema man!! To save money make one of the seats a projection or large screen system (could be run by a Mac Pro) that can be viewed by several people at once sharing. If you must put outdated machines in there, at least make them powerful enough to be able to type notes and mail them to yourself. If you could log in and annotate or at least put bookmarks, or type a list of things to research, it would be better, but I am expecting anything you hard wire will likely be clunk and unusable quickly. Much better to make it flexible and growable.
2.5. Growth of the archive. Another thing, the library I knew was really nice but I felt it was quite static. Not that I worked through the whole collection no way! But there were every month, sometimes every week I think seminars held by artists there. It would be natural to try and record them, or store a duplicate of something else an artist or professor might record themselves, and add them to the library. So it should and will grow. As hardware gets higher capacity and cheaper you will have an unhomogenous bunch of different systems. If you just make them all IP addressable it should be okay, maybe you want to consider ZFS. Certainly 32 bit will not be enough either. So I think you should also plan for the archive to grow, and also make it possible to record in high quality in all spaces in the museum - performance, seminar, and heck maybe it would be neat to be able to have a chat with a visiting artist in the coffee shop or lounge which could be unobtrusively captured via a mic/camera combo, enter a filename via your iphone and record something for the archive. Maybe that is even how reporters will write for newspapers in 10 years. Anyway, think about what people will need in 10 years and what will seem clunky. Some things will get cheap over time but you should have some minimal ability to do large projections, video recordi
Okay look, technology has advanced to the point this probably works for 90% of the time awesomely. Just get a modern server, and someone fueled with Coke in front of it. The combo is way more powerful than whatever they had originally.
First make an api to the switching network, then map the nodes to match the geography roughly, using google if you must. Throw a machine learning algorithm that simulates lots of ants (okay cars for this project) going through the traffic signal graph and each can have a few characteristics like average speed to destination, gas consumption, frustration, etc. The traffic signals can be tweaked by hand or you can give them genes for different oscillatory patterns.
If you start with the main arteries first I bet you could quickly develop a traffic signal plan that works great. How much you want to bet this could be done by a bunch of suitably competent types with a nice big prize in a hackathon? Now I'm not saying to plug the network into Wolfram Alpha's server farm but it just might work...
I too was pretty skeptical at first but now things are starting to get spooky.
Face it, the odds are really small that this would happen. It is more likely you have a scientist who is very worried about bad things happening, and who has actually intelligently sabotaged the system by trial and error, ending up with the old baguette-on-the-busbar trick which must be a physics joke among French speaking countries.
On the other hand, if the LHC is really a universe suicide machine then there must be an uncountable number of universes which died, due to the baguette hitting the wrong exterior portion of the LHC, etc.
Particle physics is one place where extremely big or small numbers are a matter of everyday discussion I expect. Unless a perpetrator is found soon (and boy I really hope one is), I doubt this will cause consternation among the public. Maybe if there are some smart people at LHC they may be freaking out now.
But consider what if the "running the LHC kills the Earth or maybe Everything" theory is true. First of all, almost all but a small fraction of all universes stemming from our many universes existing as of say a year ago must be extinguished by now, the odds of a bird with baguette causing a short-circuit being so small. If one more freaky incident occurs (as must happen according to the theory) then I think you will start seeing a lot of people freaking out and trying to stop the thing.
Also, if "LHC kills Earth" is true, and "there is a multiverse built like an ever branching tree" is true, then building the LHC is an act of pruning the tree and the number of universes in which you may potentially exist. In other words, there are way less alternate histories now, so existence for us is a lot less richer according to one way of looking at it (the number of multiverses). Another way of looking at that might be, is that it might become easier or harder to do things like quantum computing, or evolution, or scientific advancement toward a singularity, assuming that some connection among the multiverses, such as gravity, exists.
GP is right. Government should focus on doing what government is needed for success, such as determining standards for formats that everyone can use, with input from academia and industry. For example a human readable parsable format that one could embed in a web page for semantic metadata. Or funding open source software to make it easy (cross platform) to input such data (I am thinking of information about cited papers or books). Typeset information is nice but we already are drowning in information - how many pages of Google results do you usually look at? And we need help before generating 10 times as much.
Why PDF is bad: - It is a potable typeset document package. Not a data sharing package that could be pulled apart easily with tools automatically. - PDF is extremely hard to parse, and using current free software does not always give good results. - You destroy useful document structure, or in the case of ASCII text parsability and small size, when you convert to PDF. You can't just convert back to the original. - It takes significant processing power and commercial software to display well and reliability as far as I can see. Having just gotten the latest Mac I feel like I'm in a dauntless battleship, but I have had many trouble with different unix tools in the past. - Scientists publish PDF too but then also use other formats for data. For example on arxiv, one scientists recently published animations inside a zip but it was hard to find the link - It is difficult to manage bibliographic information automatically. - It is proprietary - It requires a huge amount of data, and arcane knowledge, just to build a parser that works most of the time (such as for Asian languages especially).
If you go to news.google.com you can see Murdoch is being tricky but not entirely incorrect.
A headline shows up and when you click on it you are sent to the publisher's website with its ads. However, one sentence is indeed printed, and a small version of a photo may be displayed. These are probably being done without permission.
I worked in the photo news business in the early 90s and know that photos aren't free, even if they are printed small. (For example we made a lot of money selling tons of tiny photos the same size to a magazine called AB Road.)
Of course you can't really tell, it might be that they are getting the one sentence of text and the small photos from companies they have made a deal with, maybe even the content comes from Murdoch at some point but then he loses control of it. This is a very murky area. I could certainly see news companies cutting deals with Google for more air time.
Also, no ads are actually shown on the Google News page, as far as I can see when not logged in. The purpose seems to be to lead people to the publisher's site, and even suggest reading a similar article in more than one publication.
Murdoch probably doesn't like it when people have lots of choice to read things that aren't his. And, he should clearly be paying Google for the work they do (and their overhead) in bringing people to his website generating ad views on his site, and not the other way around.
Google has been biding its time and taking things slow. They have been scanning in tons of dead tree books ("for search purposes"), and the next steps will be to 1) actually sell book reading to the public, and 2) sell news. A google service that downloads a customized newspaper to your e-ink tablet (which will arrive very soon) would be useful.
So Murdoch has spent all this money making an empire, but it is still a dead tree publishing empire, and that industry is not doing well. Meanwhile Google, even if it does bring in eyeballs to Murdoch's sites, is really anti-empire, offering lots of alternatives to Murdoch. Maybe he thinks he could gain loyal readers if only the clock could be turned back and Google disappeared. Instead the clock is spinning forward and he is clueless about what to do.
What he really should do is go over to Plastic Logic and buy part of their company. But he instead chooses to start a vocal war of perception, in an attempt to move public perception of Google toward the evil side. Murdoch should be building digital news services, instead he is leaving that to others.
What I get from it: - He's been working on it for at least 3 years actually. And it matches with results others have found so far. Hilbert saw a hint of this in the 1920s. It comes from Einstein's work but until about 2005 it had only been solved for a slow driver source, and then only to first order approximation, so it looked like there was not much effect. For relativistic, time-dependent sources, even a weak gravitational field can be repulsive. - According to the 2005 paper, any mass moving faster than 0.58c will repel any mass ahead of it. Under that speed and the ship gets sucked in towards the driver. (Oops!) I don't see this as a drive mounted on a ship myself yet but maybe I misunderstand it. Seems you could shoot a particle beam at the ship to accelerate it in roughly the same direction though. - Such a relativistic driver would accelerate a ship standing in front of it through a gravitational repulsion field acting in a narrow cone within which the ship is found. Occupants would seem not to feel inertia. (This cone is not apparent from the older animations which seem to be more talking about passing a black hole.) From 2006b:
In the "antigravity beam" of a speeding star or compact object, however, a payload would draw its energy for propulsion from the repulsive force of the much more massive driver. Moreover, since it would be moving along a geodesic, a payload would "float weightlessly" in the "antigravity beam" even as it was accelerated close to the speed of light.
- The limit of acceleration can be calculated using equations of motion in a Schwarzschild field (like you are near a black hole). The repulsion field will be evident to a distant observer if the driver is a mass moving faster than 0.58c. - If you look at Felber's 2005 paper Exact relativistic "antigravity" propulsion and download from that page the tar-gzip archive there are some cool video clips. The driver is similar to a black hole. You can see in v58 that if the driver is a black hole moving towards the ship at near the speed of light, the ship gets pushed ahead of it. (the animations don't show the kick to higher speed that is discussed in 2006b). - I read the driver as a relativistic particle beam aimed at a ship but maybe not so, there is speculation that an appropriate driver might be found in space. The idea (from 2005 paper below) is to discover an approaching relativistic black hole and maneuver near its trajectory while not too close to be hurt by its tidal forces. Sounds tricky, and depends on how broad that cone is. - Reference [11] in the recent paper is here (Apr 18, 2006) and animations in the source seem to describe the ship's possible trajectories. - You need a driver with a pretty strong field to be able to kick the ship way up toward light speed, otherwise not as much bang (can only then accelerate the ship from rest to the speed of the driver). - Much stronger effects may be possible if you use a rotating compact driver mass, which would generate a strong Kerr field and could impart energy via inertial frame dragging.
My question: Are there any events that could be hypothesized that are likely to generate a signature easily detectable by radio or X-ray telescopes?
I though
FWIW I was hurt then came to an understanding

Learning Ext JS
·
· Score: 1
FWIW I was planning on using ExtJS in the beginning and got hurt too. They sounded insane the way they were changing the liscense. I spent a lot of hours trying to figure it out and wrestling with do I want to do it or not, and it would have been a nice demo for a small but quite useful site and they could have used to promote their project.
In the end when it all settled out my conclusions were: - If willing to give up the front end to them, then fine - Not at all willing to accept any idea of "tightly bundled" somehow giving them GPL access to my server code - Figured it didn't make much difference for a small site, so didn't impact the project much - But probably best to be a commercial customer and I might want to tell my client and recommend buying it. - I lost a lot of time but the final product they provide looks to be of high quality.
I ended up not using them but might consider it again. It looks nice. They were total idiots and might still be but it looks on the surface at least like the technology works / is sexy.
I would consider it a commercial thing to buy. I am quite uneasy about their claims about what GPL means even now and hesitate to wade into that again.If anybody has success using it as GPL please describe your experience and how you understand it now.

Here are some links I found to papers describing the software used.
FWIW I am also intrigued about what is happening at this planet. I could imagine: - tremendous storms at the twilight zone, perhaps mixing in elements from the cold side, or maybe just spreading ash worldwide? - With the solar winds above and heat from below, it might be like a fluidized bed reactor with all kinds of things being created - all kinds of compounds. Falling gems indeed! - Solar wind buffeting the silica and other things in the atmosphere, could perhaps create spongy material, aerogels, glassy wings that whirl toward ground like maple seeds. - life possible? Maybe somewhere in the world..
Note that according to the abstract of Schaefer and Fegley's Vaporization of High Temperature Magmas on Io "Galileo NIMS observations indicate magmas with temperatures of 1700-2100K on Io. Vaporization of rock-forming oxides should occur at such temperatures. "
Also Exploring the Environment of Volcanoes gives for Earth: 2000 degrees C: Iron-Rich Rock (i.e. still rock even while under tremendous pressure 500 miles underground), and 5000 degrees C: liquid iron
(2900 miles underground).
There is another program called CONDOR that Fegley and Lodders made, which is described on their site. (See condor2.html for algorithm info.) This program is for gaseous atmospheres.
IANAP but based on reading temporal magnifier article the conclusion is that this is cool stuff that is intentionally being massively distorted by New Scientist in a UFO-craze way. Totally turns me off that mag now.
The paper is relatively readable even if you are not a physicist. Basically there is nothing spooky going on as New Scientist would say. The researchers developed a way to greatly stretch a short signal to a long one, is all.
The problem as stated in the Nature abstract, is that the science of photonics delivers such super-high speed signals that electronics are not fast enough to cope, you'd need a computer built of optical circuits. So this is a hybrid photonic and electronic circuit that delivers the next level of sophistication in enabling people to handle high speed signals.
Older ways of analyzing brief signals are limited to signals of low bandwidth, or they only work on repetitive ones, or they are hard to read out quickly. For example you could take a short signal and spread parts of it across several different detectors in space, but that isn't very good.
The researchers used a totally different approach. In information communications science it appears there is an equivalence between the way a signal can disperse diffracts in space and how it disperses in time. One method called four wave mixing (FWM) can be used to stretch out the signal in time.
The scientists at Cornell used FWM but introduced a non-linear process that stretches the signal much more. The process is not just linear, it is quadratic so you can get exponential amounts of stretching.
They call this device a a time lens, as it operates in the time domain, the way a normal optical lens works in the spatial domain. It even has a similar quality they call its focal length. The "lens" can "magnify" (stretch) a very short signal into something long enough that it can be analyzed.
It also can be used in reverse to "shrink" (compress) a signal in time similarly. For example as a demonstration they created a sequence of pulses each 33 picoseconds in length and then compressed each pulse in the sequence to only 4.5 picoseconds in length using their time lens as a compressor.
The lens can be set at different magnification factors, and the maximum they achieved so far is a world record, 520 times magnification. It is very cool and the idea of usign an optical paradigm in the time domain to create a circuit that is a "time lens" seems to be a very powerful technique that will generate a lot of further advances and applications.
I have not used Livescribe recommended by another poster. But it seems to me you will not be able to record your audio unless you actually walk to the blackboard with your tablet. Of course if you are always in tablet mic range then it might be okay.
Another thing is quality. You can get a pin mic (see audio technica brand or there are others) and voice recorder (they all have sd cards and usb these days, the most popular one for business will record 1000 hours or less at MP3 quality, best I am told is Olympus but there are other brands and some are pretty small).
This might give you better quality and you can pin the mic to your lapel or shirt front while slipping the recorder in your pocket. But if you can indeed just use tablet for all drawings and always be near it you might have good enough quality plus be able to synchronize. Of course this assumes you have a way for the student to play it back. I think personally it would probably be much better quality if you do this:
Create written course notes in advance with nicely written equations etc. on your tablet Draw on blackboard with tablet and record that, give this and the advance notes to the students on your course website. Use voice recorder to get high quality sound and dump the sd card to your website. Verbally say which page of notes, or blackboard drawing, you are talking about. Optionally have a video camera synched to voice recorder, depends on how animated you are and how important are the gestures at the blackboard. Maybe not so important. Then organize the files on your site, with a wiki or blog and maybe a rss feed to let people know when it is updated. Maybe scribd would be useful too. I saw some info at http://www.slideshare.net/hebertm3308/interactive-classrooms-presentation and http://www.kn.pacbell.com/wired/fil/pages/listweb20s.html
Bottom of the Top500 as of June is about Max 17 Tflops, Peak 37 Tflops. So if this is really 0.6 Tflops well... maybe one of these would make one node of a many-noded supercomputer.
Interesting to compare to a rack of Apple Xserves. Each rack is 8 cores (same cpus as the Octane III it seems). Again about $50k for 80 cores. Looks like sgi is aiming at that segment.
Can anybody with Xserve experience say how these would compare? I see Apple has something called Xsan too.
Glad to see another news story about this fascinating concept not covered in the press. But since it is obviously a story that is some years old you should credit the discoverer of the superhighway, Martin Lo, whose calculations for a halo orbit around solar lagrange point IIRC made possible the GENESIS mission.
It would be very cool if someone could comprehend the math involved and make a simulation of how it would look in the solar system. I don't understand if it is the multibody problem but have an unwarranted idea that a very rough approximation could be done on a modern PC. Haven't actually ever seen a diagram of such paths.
Should remember they are supposedly near to energy free and very slow. I remember posting on slashdot maybe a year ago about this in fact. It would be useful for creating a solar system wide IP network covering sensors that would report on observations of objects for NEO spaceguard and perhaps for astronomy too.
This would be a perfect thing for the Haiku people to build into their BeOS alpha.
I was shopping for projectors since I wanted to make a touch enabled tabletop - I've seen similar things done by art & tech teams on the net in the past. Haiku would be awesome for its response, quality of media playback, and speed of development I imagine.
And, finally the device Jean Louis was trying to get BeOS into! I bet you could sell touch enabled Haiku to a manufacturer for use in their surface-style desktop / projector / camera combo or to distribute as an open source project.
Yes could be done in Linux with less flair I imagine too..
Electrons act like both particles and waves, following the laws of quantum mechanics. They are not really like moons traveling around planets in a neat circle.
I'm not a physicist but my understanding is that each element has a different number of electrons balancing the positive charge of the protons in the nucleus. These electrons form electron shells which are at different energy levels, and the shells are composed of a combination of atomic orbitals.
Quantum physics says that one cannot know where an electron is until you measure it. The three-dimensional geometric shape of an orbital indicates where the probability is highest that the electron will be found, but it could be just about anywhere. Some orbitals are spherical but others are very different shapes.
Not sure which statement you are pointing at. A recent slashdot interview with a security researcher investigating how to secure hardware says she runs windows in three virtual machines (like virtual pc) on her mac. They are named red, yellow and green IIRC with e.g. green being just for Internet banking and nothing else whereas red would be for daily surfing but it is zeroed on each virtual boot. Regarding iphone being invisible, I read in a post that the iPhone after the latest OS X update is no longer visible in network prefs on the macbook. However the above poster says actually tethering is enabled, so maybe all the tons of posts I have read about it on the net are all nuts. I will wait and see as an iPhone is desirable but not a survival requirement.
Really? Thank you. Then back in the running. One thing you can say about Apple is they make things you want. The Macbook Pro is #3 in top 20 laptops but actually has more hd and cpu than the top 1 and 2.
As posted recently I really wanted an iPhone because of the big screen (big Blackberry not available here, only Bold) but was going to get Blackberry because it allows tethering, my friend said. Then I found out iPhone could too. Oh, okay I go to buy an iPhone last week.
THANK GOD I did not buy the iPhone. I lucked out since they need special papers to buy through my company. Now I'm just going to sit back and watch the fireworks until Apple rolls over. Someone should tell them what happened to Amazon when Jeff stole 1984! (Which reminds me of a famous Apple TV ad... Listening, Steve?)
For the record I went into a store yesterday looking at a new loaded Macbook Pro to go with my planned iPhone, my first return back to Apple since leaving it some years ago for Linux and Windows. I always remembered how Apple screws its customers, going back to the Apple III (yes I had an Apple II Integer Basic/Pascal too). A LONG time Apple lover, who dared to return but NOOOO! Tough love indeed. I was going to run XP in virtual pc instances on the Macbook but it is starting to look like corporate crap sticking out of the corners. I had no idea the iphone would be invisible from the Mac!
My impression is that these prizes are created for specific milestones that delineate an evolutionary path for private, entrepreneurial, kickass space industry. The first steps are simple, and they get harder. They reward excellence for people competing in that space, the best get fantastic press and some (probably not all I would expect) of their investment back. The space elevator competition, the AI automobile competition, etc. all proceed a pace at a time. With respect to your question, IANARS but the idea of skunkworks space developers applying the most modern technologies to achieve aerospace development targets in what sounds like Internet time is new. Also X-Prizes create a competitive community that is a visible target for investors, engineers, and even government planners. Where is the civil space program? THERE!
Most young girls will not realize or care about this I expect.
But to put this in perspective, yesterday I saw a tasty-looking home NAS on the shelf of a store in Akihabara, Tokyo. The high end model, which among other things has some terabytes of RAID and a mysql server in it, can download bittorrent without having a pc connected to it.
I figure people will put music or video on their home-NAS, and maybe if it can be made easy even share the NAS with a bunch of friends. Then just stream to your phone. Encoding for normal phones, and accessing from them, might be a pain. But I expect the more advanced phones will be able to work great with them. So if you move the media off the phone, then you can stream from a home NAS. Everything has SD or microSD in them now too. Will the DRM cover that too?
Slashdot Mirror
We really need an analysis done and report made to the public security community. This is a unique chance to discover what are the real vulnerabilities to the mass of computing power on which criminals prey.
A federal or state level court needs to authorize the researchers to do such an analysis. Even a single state would be enough, if the zombie IPs can be reliably mapped to that state. I would envision the analysis to include:
- Make a full study of many individual zombie PCs: What antivirus, firewall, OS, applications, etc. are installed, including version numbers and a fingerprint (to identify whether they are super-vulnerable copies from warez sites, infected OEMs, etc.).
- Monitor usage of a small number of PCs to identify what user habits lead to zombification, based on the theory that these PCs will become zombies of another botnet soon probably. What should be monitored, and for how long?
- Contact (with law enforcement assistance) a small number of individual users to interview them. Publish anonymized interviews for representative cases so the public can better learn what constitutes dangerous habits.
- Report anonymized individual representative cases, trends and statistics.
Discuss whether the defanged botnet should be used to destroy other botnets. Too much discussion would alert the other net owners. People could opt in based on a message sent to infected PCs, if the authorities support it, but unless those bots are hardened they might open the owners to retaliatory attacks.
At least, let's find out if antivirus really doesn't work, what habits led to botnet creation, and how can we alert zombie owners so they adopt more secure practices.
P.P.S. Also I would recommend extending the wireless network to the seminar room. It would allow a computer assisted meeting (CAM) where audience could ask questions instead of just 1 or 2 people and 1 mic then time's up, people could pose questions to that day/time's seminar blog or to a CAM system and a moderator could pick good questions, or the speakers could also type answers, or follow up later. It would be very cool. CAM used to be too expensive for large numbers of people (I once propose one for 2000 but clients are too expensive) but now everyone has a laptop or a cellphone for texting. It can be done now. It would be nice if you could provide multiple projectors too. Speakers will want to run their applications they built and maybe need higher resolution, or show a closeup of the speaker while he's talking in another projector.
P.S. If you go to the ICC page you can see their Metaverse / Hive project, an open video archive. I think some links are Japanese but they have recordings of seminars too. I too dislike the disc changer idea but I don't know how much money you all have. If possible do as some other posters say, bring much high bandwidth cabling around and also put in clients with much horsepower. I was thinking of quad Mac Pro with large screen at each location. The huge fast SAN someone mentioned also sounds scrumptious. If you can't afford it all now just block out purchases in the future maybe. But don't get crappy old stuff.
Anyway on the Hive top page you see it is bilingual, and there is an announcement about licensing, and you can say click on an "ICC artist talk" like this one for Knowbotic Research who are very cool. There is info about the artists and their homepage, plus a link to the exhibit page from when their exhibit was in the museum (yes you have to archive all of that too, and probably hire an admin to manage updates, a student will do). There is a streaming link. And (whoa I just discovered this and will be diving into the hive from now on I assure you) a DOWNLOAD LINK! Where you can get a zip file of the talk which is perfect. The library makes it CC licensed and open to the Net which is also perfect. The file is a WMA at 720x480 and 44Khz audio, perhaps lower quality than you will have in the future. Check it out, the beginning of the file is Japanese but advance a bit and it becomes English. It would be nice to have an editing studio so you can add other language tracks in the future (or just subtitles, that would be easier in a separate file). In this video file you can see how they are having a panel discussion, and the speaker plugs their laptop into the projector. Figure you will have very high-end machines on stage potentially, or connecting to/from the net. And provide a HD camera for the view of the stage. Hope this helps, the ICC really built just what you want and it looks like they have kept it updated technologically. They even have a metaverse project. You may need to host virtual worlds in the future, I guess that is pretty likely right now. Many artworks are in 3d virtual spaces or in a large web of webpages, like i love bees and david blair's wax web (which also included video and was so slow over the web of about 95 or so.). Consider Blair was IIRC the first artist to plug a VCR into the net and stream it, you are definitely going to be having a taxed infrastructure and all you can do is make it delightful to be there and work with boosting it. A big SAN is probably something you need.
One thing I liked from something someone mentioned, the video jog dial (not really a jog, you spin it with your finger in the hole to advance or rewind video). That client looked like crap though. I'd consider how do people use the system and maybe for each station also consider (it's not that expensive) some usb add-ons like a tiny side screen for navigation (if you are full screen video), a 3D round shuttle like this or maybe this, and a cheapo printer. I have no idea if 3d printers will get cheap one day (well yes there's a nice tabletop one I think) but just something now that people can print out a screen shot or notes. Of course best if they can just mail to themselves maybe, then no need to stock paper/ink.
I know one media art museum that has a video library, state of the art 10 years ago and still useful but I could make some recommendations. I am talking about the NTT ICC (Intercommunication Center) and I maybe remember it in a distorted fashion, and it was reduced in size too, but it is at the New National Opera at Opera City, Hatsudai, Tokyo. I haven't been there lately but check it out at http://www.ntticc.or.jp/index_e.html
1. The museum has a big, very expensive SGI machine (20 cpus? I forget) used for graphics intensive installations. I believe it was used on a CAVE, a gesture recognition articifical life generating installation, an interactive 3d sculpting program, etc. Nowadays I would expect you just provide a rack of machines like Mac OS X servers or the new genre of "deskside supercomputer" i.e. many graphics boards, many (up to 80) cpus, etc. If you are going to provide resources for installations. Also a studio where artists can come work to build the final stage of their installations, would be awesome (video and graphics studio would be cool).
2. As for the video library the key is to have the content. The one I knew was a bit hard to navigate but allowed you to view IIRC interviews with artists and video works by video artists. Maybe also video documents of performance type works I forget. The headphones I think were good maybe. Screens etc. sucked. Nowadays, people have powerful laptops and they write their notes on them. Also many artworks may be created with client-side animations (like with Processing). So I would provide at least some high-end clients, and also a wireless network for people to connect their own machines. It would be nice if there were areas where one could use projection for a piece that needs to be seen big (or that requires the user to stand in front and interact) or a little room with a superior sound system, there are lots of kinds of art.
Thin client? I read it as a piece of junk that is substandard even before you install it, only able to view old-fashioned NTSC. We're in the days of HD terrestrial broadcast, blue-ray and high def digital cinema man!! To save money make one of the seats a projection or large screen system (could be run by a Mac Pro) that can be viewed by several people at once sharing. If you must put outdated machines in there, at least make them powerful enough to be able to type notes and mail them to yourself. If you could log in and annotate or at least put bookmarks, or type a list of things to research, it would be better, but I am expecting anything you hard wire will likely be clunk and unusable quickly. Much better to make it flexible and growable.
2.5. Growth of the archive. Another thing, the library I knew was really nice but I felt it was quite static. Not that I worked through the whole collection no way! But there were every month, sometimes every week I think seminars held by artists there. It would be natural to try and record them, or store a duplicate of something else an artist or professor might record themselves, and add them to the library. So it should and will grow. As hardware gets higher capacity and cheaper you will have an unhomogenous bunch of different systems. If you just make them all IP addressable it should be okay, maybe you want to consider ZFS. Certainly 32 bit will not be enough either. So I think you should also plan for the archive to grow, and also make it possible to record in high quality in all spaces in the museum - performance, seminar, and heck maybe it would be neat to be able to have a chat with a visiting artist in the coffee shop or lounge which could be unobtrusively captured via a mic/camera combo, enter a filename via your iphone and record something for the archive. Maybe that is even how reporters will write for newspapers in 10 years. Anyway, think about what people will need in 10 years and what will seem clunky. Some things will get cheap over time but you should have some minimal ability to do large projections, video recordi
Okay look, technology has advanced to the point this probably works for 90% of the time awesomely. Just get a modern server, and someone fueled with Coke in front of it. The combo is way more powerful than whatever they had originally.
First make an api to the switching network, then map the nodes to match the geography roughly, using google if you must. Throw a machine learning algorithm that simulates lots of ants (okay cars for this project) going through the traffic signal graph and each can have a few characteristics like average speed to destination, gas consumption, frustration, etc. The traffic signals can be tweaked by hand or you can give them genes for different oscillatory patterns.
If you start with the main arteries first I bet you could quickly develop a traffic signal plan that works great. How much you want to bet this could be done by a bunch of suitably competent types with a nice big prize in a hackathon? Now I'm not saying to plug the network into Wolfram Alpha's server farm but it just might work...
I too was pretty skeptical at first but now things are starting to get spooky.
Face it, the odds are really small that this would happen. It is more likely you have a scientist who is very worried about bad things happening, and who has actually intelligently sabotaged the system by trial and error, ending up with the old baguette-on-the-busbar trick which must be a physics joke among French speaking countries.
On the other hand, if the LHC is really a universe suicide machine then there must be an uncountable number of universes which died, due to the baguette hitting the wrong exterior portion of the LHC, etc.
Particle physics is one place where extremely big or small numbers are a matter of everyday discussion I expect. Unless a perpetrator is found soon (and boy I really hope one is), I doubt this will cause consternation among the public. Maybe if there are some smart people at LHC they may be freaking out now.
But consider what if the "running the LHC kills the Earth or maybe Everything" theory is true. First of all, almost all but a small fraction of all universes stemming from our many universes existing as of say a year ago must be extinguished by now, the odds of a bird with baguette causing a short-circuit being so small. If one more freaky incident occurs (as must happen according to the theory) then I think you will start seeing a lot of people freaking out and trying to stop the thing.
Also, if "LHC kills Earth" is true, and "there is a multiverse built like an ever branching tree" is true, then building the LHC is an act of pruning the tree and the number of universes in which you may potentially exist. In other words, there are way less alternate histories now, so existence for us is a lot less richer according to one way of looking at it (the number of multiverses). Another way of looking at that might be, is that it might become easier or harder to do things like quantum computing, or evolution, or scientific advancement toward a singularity, assuming that some connection among the multiverses, such as gravity, exists.
GP is right. Government should focus on doing what government is needed for success, such as determining standards for formats that everyone can use, with input from academia and industry. For example a human readable parsable format that one could embed in a web page for semantic metadata. Or funding open source software to make it easy (cross platform) to input such data (I am thinking of information about cited papers or books). Typeset information is nice but we already are drowning in information - how many pages of Google results do you usually look at? And we need help before generating 10 times as much.
Why PDF is bad:
- It is a potable typeset document package. Not a data sharing package that could be pulled apart easily with tools automatically.
- PDF is extremely hard to parse, and using current free software does not always give good results.
- You destroy useful document structure, or in the case of ASCII text parsability and small size, when you convert to PDF. You can't just convert back to the original.
- It takes significant processing power and commercial software to display well and reliability as far as I can see. Having just gotten the latest Mac I feel like I'm in a dauntless battleship, but I have had many trouble with different unix tools in the past.
- Scientists publish PDF too but then also use other formats for data. For example on arxiv, one scientists recently published animations inside a zip but it was hard to find the link
- It is difficult to manage bibliographic information automatically.
- It is proprietary
- It requires a huge amount of data, and arcane knowledge, just to build a parser that works most of the time (such as for Asian languages especially).
Finally, evidence for those who have held off purchasing their tin-foil hats.
How much of a boost from Slashdot?
If you go to news.google.com you can see Murdoch is being tricky but not entirely incorrect.
A headline shows up and when you click on it you are sent to the publisher's website with its ads. However, one sentence is indeed printed, and a small version of a photo may be displayed. These are probably being done without permission.
I worked in the photo news business in the early 90s and know that photos aren't free, even if they are printed small. (For example we made a lot of money selling tons of tiny photos the same size to a magazine called AB Road.)
Of course you can't really tell, it might be that they are getting the one sentence of text and the small photos from companies they have made a deal with, maybe even the content comes from Murdoch at some point but then he loses control of it. This is a very murky area. I could certainly see news companies cutting deals with Google for more air time.
Also, no ads are actually shown on the Google News page, as far as I can see when not logged in.
The purpose seems to be to lead people to the publisher's site, and even suggest reading a similar article in more than one publication.
Murdoch probably doesn't like it when people have lots of choice to read things that aren't his.
And, he should clearly be paying Google for the work they do (and their overhead) in bringing people to his website generating ad views on his site, and not the other way around.
Google has been biding its time and taking things slow. They have been scanning in tons of dead tree books ("for search purposes"), and the next steps will be to 1) actually sell book reading to the public, and 2) sell news. A google service that downloads a customized newspaper to your e-ink tablet (which will arrive very soon) would be useful.
So Murdoch has spent all this money making an empire, but it is still a dead tree publishing empire, and that industry is not doing well. Meanwhile Google, even if it does bring in eyeballs to Murdoch's sites, is really anti-empire, offering lots of alternatives to Murdoch. Maybe he thinks he could gain loyal readers if only the clock could be turned back and Google disappeared. Instead the clock is spinning forward and he is clueless about what to do.
What he really should do is go over to Plastic Logic and buy part of their company. But he instead chooses to start a vocal war of perception, in an attempt to move public perception of Google toward the evil side. Murdoch should be building digital news services, instead he is leaving that to others.
I looked some of the papers which include animations but am not a physicist. Would much appreciate if a competent one could check them out.
Test of relativistic gravity for propulsion at the Large Hadron Collider (the Oct. 9, 2009 paper)
and 'Antigravity' Propulsion and Relativistic Hyperdrive
presented at 25th International Space Development Conference, Los Angeles, 4-7 May 2006 (2006b as referenced on page 2 of the above paper).
What I get from it:
- He's been working on it for at least 3 years actually. And it matches with results others have found so far. Hilbert saw a hint of this in the 1920s. It comes from Einstein's work but until about 2005 it had only been solved for a slow driver source, and then only to first order approximation, so it looked like there was not much effect. For relativistic, time-dependent sources, even a weak gravitational field can be repulsive.
- According to the 2005 paper, any mass moving faster than 0.58c will repel any mass ahead of it. Under that speed and the ship gets sucked in towards the driver. (Oops!) I don't see this as a drive mounted on a ship myself yet but maybe I misunderstand it. Seems you could shoot a particle beam at the ship to accelerate it in roughly the same direction though.
- Such a relativistic driver would accelerate a ship standing in front of it through a gravitational repulsion field acting in a narrow cone within which the ship is found. Occupants would seem not to feel inertia. (This cone is not apparent from the older animations which seem to be more talking about passing a black hole.) From 2006b:
- The limit of acceleration can be calculated using equations of motion in a Schwarzschild field (like you are near a black hole). The repulsion field will be evident to a distant observer if the driver is a mass moving faster than 0.58c.
- If you look at Felber's 2005 paper Exact relativistic "antigravity" propulsion and download from that page the tar-gzip archive there are some cool video clips. The driver is similar to a black hole. You can see in v58 that if the driver is a black hole moving towards the ship at near the speed of light, the ship gets pushed ahead of it. (the animations don't show the kick to higher speed that is discussed in 2006b).
- I read the driver as a relativistic particle beam aimed at a ship but maybe not so, there is speculation that an appropriate driver might be found in space. The idea (from 2005 paper below) is to discover an approaching relativistic black hole and maneuver near its trajectory while not too close to be hurt by its tidal forces. Sounds tricky, and depends on how broad that cone is.
- Reference [11] in the recent paper is here (Apr 18, 2006) and animations in the source seem to describe the ship's possible trajectories.
- You need a driver with a pretty strong field to be able to kick the ship way up toward light speed, otherwise not as much bang (can only then accelerate the ship from rest to the speed of the driver).
- Much stronger effects may be possible if you use a rotating compact driver mass, which would generate a strong Kerr field and could impart energy via inertial frame dragging.
My question: Are there any events that could be hypothesized that are likely to generate a signature easily detectable by radio or X-ray telescopes?
I though
FWIW I was planning on using ExtJS in the beginning and got hurt too. They sounded insane the way they were changing the liscense. I spent a lot of hours trying to figure it out and wrestling with do I want to do it or not, and it would have been a nice demo for a small but quite useful site and they could have used to promote their project.
In the end when it all settled out my conclusions were:
- If willing to give up the front end to them, then fine
- Not at all willing to accept any idea of "tightly bundled" somehow giving them GPL access to my server code
- Figured it didn't make much difference for a small site, so didn't impact the project much
- But probably best to be a commercial customer and I might want to tell my client and recommend buying it.
- I lost a lot of time but the final product they provide looks to be of high quality.
I ended up not using them but might consider it again. It looks nice. They were total idiots and might still be but it looks on the surface at least like the technology works / is sexy.
I would consider it a commercial thing to buy. I am quite uneasy about their claims about what GPL means even now and hesitate to wade into that again.If anybody has success using it as GPL please describe your experience and how you understand it now.

FWIW I am also intrigued about what is happening at this planet. I could imagine:
- tremendous storms at the twilight zone, perhaps mixing in elements from the cold side, or maybe just spreading ash worldwide?
- With the solar winds above and heat from below, it might be like a fluidized bed reactor with all kinds of things being created - all kinds of compounds. Falling gems indeed!
- Solar wind buffeting the silica and other things in the atmosphere, could perhaps create spongy material, aerogels, glassy wings that whirl toward ground like maple seeds.
- life possible? Maybe somewhere in the world..
Okay. Use of the MAGMA software is described briefly in Fractional Vaporization of Hot Earth-like Exoplanets and a description of the algorithms and data used in the program are provided in
L. Schaefer and B. Fegley. A Thermodynamic Model of High Temperature Lava Vaporization on Io, Icarus, 169, 216-241.
Note that according to the abstract of Schaefer and Fegley's Vaporization of High Temperature Magmas on Io "Galileo NIMS observations indicate magmas with temperatures of 1700-2100K on Io. Vaporization of rock-forming oxides should occur at such temperatures. "
Also Exploring the Environment of Volcanoes gives for Earth: 2000 degrees C: Iron-Rich Rock (i.e. still rock even while under tremendous pressure 500 miles underground), and 5000 degrees C: liquid iron
(2900 miles underground).
You may also be interested in Heavy Metal Frost on Venus
and an overview of some of their research here.
There is another program called CONDOR that Fegley and Lodders made, which is described on their site. (See condor2.html for algorithm info.) This program is for gaseous atmospheres.
IANAP but based on reading temporal magnifier article the conclusion is that this is cool stuff that is intentionally being massively distorted by New Scientist in a UFO-craze way. Totally turns me off that mag now.
The paper is relatively readable even if you are not a physicist. Basically there is nothing spooky going on as New Scientist would say. The researchers developed a way to greatly stretch a short signal to a long one, is all.
The problem as stated in the Nature abstract, is that the science of photonics delivers such super-high speed signals that electronics are not fast enough to cope, you'd need a computer built of optical circuits. So this is a hybrid photonic and electronic circuit that delivers the next level of sophistication in enabling people to handle high speed signals.
Older ways of analyzing brief signals are limited to signals of low bandwidth, or they only work on repetitive ones, or they are hard to read out quickly. For example you could take a short signal and spread parts of it across several different detectors in space, but that isn't very good.
The researchers used a totally different approach. In information communications science it appears there is an equivalence between the way a signal can disperse diffracts in space and how it disperses in time. One method called four wave mixing (FWM) can be used to stretch out the signal in time.
The scientists at Cornell used FWM but introduced a non-linear process that stretches the signal much more. The process is not just linear, it is quadratic so you can get exponential amounts of stretching.
They call this device a a time lens, as it operates in the time domain, the way a normal optical lens works in the spatial domain. It even has a similar quality they call its focal length. The "lens" can "magnify" (stretch) a very short signal into something long enough that it can be analyzed.
It also can be used in reverse to "shrink" (compress) a signal in time similarly. For example as a demonstration they created a sequence of pulses each 33 picoseconds in length and then compressed each pulse in the sequence to only 4.5 picoseconds in length using their time lens as a compressor.
The lens can be set at different magnification factors, and the maximum they achieved so far is a world record, 520 times magnification. It is very cool and the idea of usign an optical paradigm in the time domain to create a circuit that is a "time lens" seems to be a very powerful technique that will generate a lot of further advances and applications.
I have not used Livescribe recommended by another poster. But it seems to me you will not be able to record your audio unless you actually walk to the blackboard with your tablet. Of course if you are always in tablet mic range then it might be okay.
Another thing is quality. You can get a pin mic (see audio technica brand or there are others) and voice recorder (they all have sd cards and usb these days, the most popular one for business will record 1000 hours or less at MP3 quality, best I am told is Olympus but there are other brands and some are pretty small).
This might give you better quality and you can pin the mic to your lapel or shirt front while slipping the recorder in your pocket. But if you can indeed just use tablet for all drawings and always be near it you might have good enough quality plus be able to synchronize. Of course this assumes you have a way for the student to play it back. I think personally it would probably be much better quality if you do this:
Create written course notes in advance with nicely written equations etc. on your tablet
Draw on blackboard with tablet and record that, give this and the advance notes to the students on your course website.
Use voice recorder to get high quality sound and dump the sd card to your website. Verbally say which page of notes, or blackboard drawing, you are talking about.
Optionally have a video camera synched to voice recorder, depends on how animated you are and how important are the gestures at the blackboard. Maybe not so important.
Then organize the files on your site, with a wiki or blog and maybe a rss feed to let people know when it is updated. Maybe scribd would be useful too.
I saw some info at

Bottom of the Top500 as of June is about Max 17 Tflops, Peak 37 Tflops. So if this is really 0.6 Tflops well... maybe one of these would make one node of a many-noded supercomputer.
Interesting to compare to a rack of Apple Xserves. Each rack is 8 cores (same cpus as the Octane III it seems). Again about $50k for 80 cores. Looks like sgi is aiming at that segment.
Can anybody with Xserve experience say how these would compare? I see Apple has something called Xsan too.
Glad to see another news story about this fascinating concept not covered in the press. But since it is obviously a story that is some years old you should credit the discoverer of the superhighway, Martin Lo, whose calculations for a halo orbit around solar lagrange point IIRC made possible the GENESIS mission.
It would be very cool if someone could comprehend the math involved and make a simulation of how it would look in the solar system. I don't understand if it is the multibody problem but have an unwarranted idea that a very rough approximation could be done on a modern PC. Haven't actually ever seen a diagram of such paths.
Should remember they are supposedly near to energy free and very slow. I remember posting on slashdot maybe a year ago about this in fact. It would be useful for creating a solar system wide IP network covering sensors that would report on observations of objects for NEO spaceguard and perhaps for astronomy too.
This would be a perfect thing for the Haiku people to build into their BeOS alpha.
I was shopping for projectors since I wanted to make a touch enabled tabletop - I've seen similar things done by art & tech teams on the net in the past. Haiku would be awesome for its response, quality of media playback, and speed of development I imagine.
And, finally the device Jean Louis was trying to get BeOS into! I bet you could sell touch enabled Haiku to a manufacturer for use in their surface-style desktop / projector / camera combo or to distribute as an open source project.
Yes could be done in Linux with less flair I imagine too..
Electrons act like both particles and waves, following the laws of quantum mechanics. They are not really like moons traveling around planets in a neat circle.
I'm not a physicist but my understanding is that each element has a different number of electrons balancing the positive charge of the protons in the nucleus. These electrons form electron shells which are at different energy levels, and the shells are composed of a combination of atomic orbitals.
Quantum physics says that one cannot know where an electron is until you measure it. The three-dimensional geometric shape of an orbital indicates where the probability is highest that the electron will be found, but it could be just about anywhere. Some orbitals are spherical but others are very different shapes.
Here are some wikipedia links:

Not sure which statement you are pointing at.
A recent slashdot interview with a security researcher investigating how to secure hardware says she runs windows in three virtual machines (like virtual pc) on her mac. They are named red, yellow and green IIRC with e.g. green being just for Internet banking and nothing else whereas red would be for daily surfing but it is zeroed on each virtual boot.
Regarding iphone being invisible, I read in a post that the iPhone after the latest OS X update is no longer visible in network prefs on the macbook.
However the above poster says actually tethering is enabled, so maybe all the tons of posts I have read about it on the net are all nuts.
I will wait and see as an iPhone is desirable but not a survival requirement.
Really? Thank you. Then back in the running. One thing you can say about Apple is they make things you want. The Macbook Pro is #3 in top 20 laptops but actually has more hd and cpu than the top 1 and 2.
As posted recently I really wanted an iPhone because of the big screen (big Blackberry not available here, only Bold) but was going to get Blackberry because it allows tethering, my friend said. Then I found out iPhone could too. Oh, okay I go to buy an iPhone last week.
THANK GOD I did not buy the iPhone. I lucked out since they need special papers to buy through my company. Now I'm just going to sit back and watch the fireworks until Apple rolls over. Someone should tell them what happened to Amazon when Jeff stole 1984! (Which reminds me of a famous Apple TV ad... Listening, Steve?)
For the record I went into a store yesterday looking at a new loaded Macbook Pro to go with my planned iPhone, my first return back to Apple since leaving it some years ago for Linux and Windows. I always remembered how Apple screws its customers, going back to the Apple III (yes I had an Apple II Integer Basic/Pascal too). A LONG time Apple lover, who dared to return but NOOOO! Tough love indeed. I was going to run XP in virtual pc instances on the Macbook but it is starting to look like corporate crap sticking out of the corners. I had no idea the iphone would be invisible from the Mac!
My impression is that these prizes are created for specific milestones that delineate an evolutionary path for private, entrepreneurial, kickass space industry. The first steps are simple, and they get harder. They reward excellence for people competing in that space, the best get fantastic press and some (probably not all I would expect) of their investment back. The space elevator competition, the AI automobile competition, etc. all proceed a pace at a time. With respect to your question, IANARS but the idea of skunkworks space developers applying the most modern technologies to achieve aerospace development targets in what sounds like Internet time is new. Also X-Prizes create a competitive community that is a visible target for investors, engineers, and even government planners. Where is the civil space program? THERE!
Most young girls will not realize or care about this I expect.
But to put this in perspective, yesterday I saw a tasty-looking home NAS on the shelf of a store in Akihabara, Tokyo. The high end model, which among other things has some terabytes of RAID and a mysql server in it, can download bittorrent without having a pc connected to it.
I figure people will put music or video on their home-NAS, and maybe if it can be made easy even share the NAS with a bunch of friends. Then just stream to your phone. Encoding for normal phones, and accessing from them, might be a pain. But I expect the more advanced phones will be able to work great with them. So if you move the media off the phone, then you can stream from a home NAS. Everything has SD or microSD in them now too. Will the DRM cover that too?
