Graham 18-May-2009 [4053] | You're not going to ruin the movie for us are you??? |
Henrik 18-May-2009 [4054] | Not the new one. :-) |
Graham 18-May-2009 [4055] | Gene Roddenbury or his estate executors might object ... |
Henrik 18-May-2009 [4056] | I can see why Carl says it's his favourite Star Trek movie. The computers that Spock uses are in fact Amiga 1000s. :-) |
Graham 18-May-2009 [4057] | aw geez .. spoilers :( |
Henrik 18-May-2009 [4058] | The computer that Scotty uses to show transparent aluminum was originally going to be an Amiga, but Commodore would only provide a computer if they bought it. Apple was willing to loan them the Mac. <--- Commodore marketing in action. |
Graham 18-May-2009 [4059] | someone lent them an Atari portfolio for Terminator |
Geomol 18-May-2009 [4060x3] | Reminds me of the START project at MIT. http://start.csail.mit.edu/ Remember the strange hokus-pokus REBOL script, I wrote some years ago? >> do http://www.fys.ku.dk/~niclasen/rebol/hokus-pokus.r >> hokus-pokus "What is the highest point in Canada?" Canada highest point: Mount Logan 5,959 m >> hokus-pokus "What is the volume of the Earth?" The volume of Earth is 108.321 (1010 km3). etc... |
Other strange use: >> hokus-pokus/quote "Hitchhiker" Ford: [watching the Magrathean recording of Deep Thought] Is that it? Zaphod: No, there's more. They go back. Arthur: What, seven and a half million years later? Zaphod: Yeah, they do. >> hokus-pokus #00113f == 0.17.63 | |
>> hokus-pokus/translate "Yeah, they do." "en2de" Ja, sie tun. :-) I use this too little. | |
Maxim 18-May-2009 [4063] | start is probably where wolfram got his idea from. |
Sunanda 24-May-2009 [4064] | Surprising conclusion on Gregory Higley's blog?: <....I’ve come to the realization that JavaScript is the language in common use that’s most akin to REBOL.> http://blog.revolucent.net/2009/05/javascript-rebol.html |
BrianH 24-May-2009 [4065x3] | JavaScript is a strict subset of the R3 semantics, though there's hidden stuff that isn't hidden in REBOL, and particular implementations can include standard objects that have no analog in REBOL. There's no corresponding concept for JavaScript's objects in R2, but the R3 map! type is close enough. |
The "hidden stuff" is the prototype message delegation, which can be done in REBOL explicitly. | |
On an implementtation level, JavaScript being compiled means that code really is code, rather than data for an interpreter. So JS is more like a subset of what R3 pretends to be, rather than what it is :) | |
Chris 24-May-2009 [4068] | Hmm, DOM (ok, not really what he means, but still vaguely similar): http://www.rebol.org/view-script.r?script=xml-dom.r http://www.ross-gill.com/r/qxml.html(slightly newer) |
Paul 25-May-2009 [4069] | Very cool project managment site. http://www.attask.com/ |
Robert 25-May-2009 [4070] | Looks pretty good. |
Janko 25-May-2009 [4071] | they have "View demo" button that leads to some not so small form to fill, on that page there is try @task that leads to even slightly bigger form |
Chris 25-May-2009 [4072] | Shame there's no product tour (without, I presume, signing up) |
Reichart 25-May-2009 [4073x2] | You also need to have a minimum number of people to use it. In other words, you have to sort of buy in all hog from what I understand... |
But they do have some cool features... | |
Paul 25-May-2009 [4075] | You can get more of a feel for it here. http://www.attask.com/overview/product-tour/project-management |
Henrik 28-May-2009 [4076] | Future spacecraft can use pulsars as an interstellar GPS with a precision of one meter: http://www.technologyreview.com/blog/arxiv/23576/ |
Reichart 28-May-2009 [4077] | Great, the aliens "will" find us.... |
Graham 31-May-2009 [4078x3] | Google's new collaboration tool http://wave.google.com/ |
Kind of underwhelming. | |
The spelling corrector spelly looks interesting. | |
Pekr 31-May-2009 [4081] | I already pointed to in in Links group. Looks interesting. I thing that we might have here some chance with R3. Maybe, as a "killer app", we could think of alternative client frond-end for services, which have public APIs. That way such clients might be downloaded by millions, making REBOL a bit more popular :-) |
Henrik 2-Jun-2009 [4082] | Project Natal for XBox 360 looks very interesting: http://www.xbox.com/en-US/live/projectnatal/ |
Pekr 2-Jun-2009 [4083] | utopia .... |
Henrik 2-Jun-2009 [4084] | http://kotaku.com/5274554/molyneuxs-milo-brings-a-virtual-child-to-the-xbox-360?autoplay=true How it's used. |
Pekr 2-Jun-2009 [4085] | I like this one - http://www.camspace.com/- allows you to take any object for navigation ... |
Henrik 16-Jun-2009 [4086] | A new type of harddisk designed to compete with SSD. Very interesting: http://www.dataslide.com/ |
Gabriele 16-Jun-2009 [4087] | that looks very cool! |
Graham 16-Jun-2009 [4088] | Is it a magneto-optical drive ... like we had years ago? |
Henrik 16-Jun-2009 [4089] | No, it basically a harddrive with a rectangular magnetic plate, and instead of one head it has millions sitting in an array in another plate above the magnetic plate, placed on a very thin lubricant. the thing is that the heads can move up to 250 micrometers back and forth above the plate using a piezo actuator. Everything is tightly packed together with no loose parts. There isn't much motion and the frequency of the motion is only about 800 - 1000 Hz. However the head arrangement allows for massive parallelization of read and write ops. Currently only 64 heads can be accessed simultaneously, but I suspect this number will go way up. If the drive is idle, no power is used as nothing is moving. Due to the low frequency of motion, there can be a latency of about 0.5 ms, but the read/write speeds far exceed that of SSD. I suspect this frequency is used to avoid thermal and power problems. The difference here from SSD is no need for specialized file systems, current manufacturing methods can be used and it uses even less power than SSD. It can also freely be scaled and adapted to 1.8", 2.5" and 3.5" drives, from what I can see. The durability for writeops on the same sector would be same or better than a harddrive. |
Sunanda 16-Jun-2009 [4090] | I can see it reducing latency [head movement time] but rotational delay is likely to be the same. You could optimise for that, but that would need tweaks to the file system. Maybe they got the inspiration from 1950's drum storage -- one head per track :-) http://en.wikipedia.org/wiki/Drum_memory |
Henrik 16-Jun-2009 [4091] | Nothing is rotating. |
Sunanda 16-Jun-2009 [4092] | Sorry -- my mistake. There's some interesting discussion of the device in the comments here: http://www.theregister.co.uk/2009/06/15/dataslide_berkeleydb/comments/ |
Ladislav 16-Jun-2009 [4093] | seems, that digital signatures are becoming quite insecure these days http://www.secureworks.com/research/blog/index.php/2009/6/3/sha-1-collision-attacks-now-252/ |
Maxim 16-Jun-2009 [4094] | wrt the HRD drive: 500MB/sec transfer rate at 4 watts !!! |
Reichart 16-Jun-2009 [4095x2] | DataSlide...finally! |
Of note, about 20 years ago I wrote up a paper to build a camera with a 100x100 CCD that could capture huge images by vibrating the aperture (which would be small than a standard pin hole). The speed of your CPU would control the time it took, thus faster computers = higher ISO values, that simple. You would also be able to point it at something far away, and tell it to focus on that region, thus getting a clear image even at a very far distance. This is still worth building today. A $10 camera that takes 10Kx10K image in about 1 second, not bad. Through software you could remove things that moved as well, for example cars that park over night, people walking around, etc. Over several days you would end up with a crystal clear image of anything that was not moving. | |
