Ive seen lots of suggestions for speech to text, but if you have had any experence with regular powerful PCs and speech->text you will see why that wont work on even a 2ghz intel system, let alone a pda/cel phone. (Didnt we just have an ask slashdot about this?)
A wire frame of a face only requires slightly more CPU power than processing a WinAmp visual (No 32 bit color eyecandy here) and i have actually seen a visualization plugin (For ge-force, avail for winamp and itunes as well as some opensource packages) that has a module that draws a face and it in a way moves with the sound. Granted that was not its design, it was made to look good, but obviously with a few changes it could be made to acuratly simulate a face and mouth for this very purpose.
Im all for any technology that makes interacting with a computer easier. While I personally would prefer direct sound into my ears over this, I also concider myself lucky to have that ability compared to those that dont.
Personally Im all for the direct brain connection, but i have a feeling thats a ways off yet:)
You can do this. First to use BGP you must have a block of 16 C class's (a/20) either from ARIN ($2500 per year) or from one of your ISPs (variable rates)
This is the smallest block that the internets border routers will 'see' a BGP route for. Anything smaller will be ignored and you will not be able to reach those networks.
Next you need both ISPs to add your ASN number to their routers so the internet as a whole knows there are more than one route to you.
As i seriously doubt you have anything above a personal cable/dsl account, they are going to raise your rates accordingly.
In addition, you will most likely want two connections that are atleast a megabit in speed, as anything slower will make BGP routing table transfers/updates to your router a pain in the ass. But it is technically possible with slower links.. It just takes alot more time and will be slow to respond to the global routing table changes.
You also need either a router or a PC router that can do BGP. BSD and linux can do this, so you wont need to buy a cisco capable of bgp, which is fortunate as they are usually rather pricy.
So for $2500/year and around $500+/month/isp you too can do BGP.
It could be fun messing with these. Imagine 10 or so pocket radios modified so their speaker leads were clipped, all on and tuned to different stations, all wired into one power supply that you connect in your trunk.
Let the billboards figure That one out!
Then again, my experence with radio anymore is 2/3rds comercials and only 1/3rds music, and of that small percent, under 10% of the time is anything i care to listen to on, so to me this wouldnt be much of a problem.
The billboard idea itself is sorta neat actually. However knowing that soon after they will have cameras to take pictures of your licence at the same time and match that to who you are using the wonders of databases, may make the jamming option more attractive.
That is if you dont want them to know what you listen to.
So if blocking popups is stealing, does this mean that when their site is unavailable they are obligated to compensate us for the downtime their site was unavailable?
So many times ive been upset because a site i needed to get to was down.. At long last justification for getting money for my loss!
After all, im not paying my ISP for bandwidth just to have these sites be down stealing information from me.
Christ. When someone makes something very useful, small, and in this case CHEAP, all you can do is relate "Well if its attached to the internet it MUST be insecure."
Get a fucking CLUE people.
Ok, if you are too inept to know how to secure anything right, yes i would worry about having this too. If i was you in that situation, id worry about most of the things normal people do through out the day.
[saracsm] Oh my god with one small piece of metal a person can get access to my whole house, and another piece of metal gives them access to my car?? The horror! Wont someone think of the security?! [/sarcasm]
Yes, give an idiot power and the idiots power can be exploited. By adding the internet in there, that still wont change anything.
Does this mean the world shouldnt have this ability? NO!
I for one would love to have remote access control and monitoring for my whole home. I however would also make sure it was secure.
Just because you arnt security experts and so trust M$ to do all of your security work for you and their ineptness lets you down does not mean that is how everyone else would be as well.
Use some comon sense. If your oven is attached to the internet, and that gives it the possibility of starting a fire, well it sounds to me like one should build in safeguards that CANT be overwritten by the remote control to prevent that from happening. An oven already wont get hot enough to simply burst into flames.. and if it can, that is far from a problem with how it is controlled.
I would also love for my car to be remotely monitored and controlled. Imagine the 'bad-ass' points you would get by foiling a car thieft this way. Do i worry that some script kiddie could break in and use this aginst me? Of course i do, thats why i think of all the ways one may go about doing that and add measures to stop it ahead of time.
Would i trust MS to make something like this secure? No.. Would i trust this guy? Depends, if i could look over his work I may be convinced to trust him. If i couldnt, no i would not. Would this stop me from adding my own security in front of all these appliances? Never on your life.
When people come up with new abilitys and resources for doing things such as this, we also must come up with new ways to make sure they arnt abused incorrectly. The two come hand in hand. But at the same time, one generally learns/discovers the way to do something before how to use it correctly. Security will come very shortly after, and just because something can be abused is no excuse to stop its existance or not continue learning.
I hope sony labels these discs as CDs and gets their asses sued for doing so. If it doesnt follow the book standard, its not a CD, and they are not legally allowed to call it such.
At this point it is a disc the same size and shape as a CD with similar data on it, but it is NOT a CD.
They need to be forced to not steal the label 'CD' or 'Compact Disc' for these whatever-they-are things. I hope phillips sues them for it too.
The quark traveled through the earth in 0.73 seconds, the shockwave that resulted is what caused the earthquakes, and the shockwave itself, traveling at the speed of sound, took 27 seconds.
Oops, I think I may have accidentally forwarded my 5000+ spam spool for the day to that email address. Silly me, must be more careful about those typos!
Our company does something similar but we run the service ourself.
Two machines in outside COLO centers, which among other things, run BackupPC software http://backuppc.sourceforge.net/
Its one of the better backup packages out there and I would highly recomend to anyone that likes live online backups to disk.
The software uses tar over ssh for unix and smbclient for windows, can backup hosts on static IPs as well as by netbios names for windows clients or unix DHCP clients.
Restores can be done directly with the tar over ssh / smbclient options, or it can send the files in a tar or zip file over your browser.
It does full backup and incramentals, and uses hardlinking as well as compression on the server side.
275gigs of data accrost multiple machines for the past month packed into 42 gigs of space on the backup server.
Best part is its live, so restores are quick and easy.
You also define an owner for each machine, and when you log into the web frontend with a user/pass, that user only sees his/her own machines. Of course you can also define admin users that see all machines, or can even have only one user that is an admin and not use that aspect.
Sorry to sound like an ad, but this backup package is best for the price if you run your own datacenter or network with a spare fileserver.
Run one local and one over the net from a colo and your good to go!
I use the same keyboard on my windows XP machine (Yes I know I know, but you have to go with what works):)
I had problems with the apple/window keys being where ALT is expected as well, as well as the problem of F13-F15 not functioning as printscreen, scrolllock, and pause/break as expected. The help button is read as insert as expected, but something about those F keys must make them show up different.
The apple USB keyboard took a little getting used to because it has different feeling feedback, its definatly not clicky, but its totally quiet as well.
If you are looking for the click feel, i dont think the apple keyboard will give you what you want.
Personally I find its feedback feeling much better.. but to each their own!
To me providing a patch in source form is exactly the same as providing a description.
You are right.. and reading the patches source would be just as much of a violation of the DMCA. You are only allowed to install the patch blindly without knowing what it will do under the DMCA.
If they wanted to be true bastard operators (Which some may even aggree they should in this situation) they would block p2p 100% from the resnet IPs and provide one single website interface to p2p networks, and keep full control over this application. That app is given limited bandwidth and download queues, and monitored for what is downloaded. If you d/l something copyrighted, they should report you to the authoritys, and if you are convicted of violating copyright, you should be expelled.
You cant argue with the above logic, as if your not breaking a law, there is nothing to worry about, right?
Its amazing how many people bitch and moan that they arnt allowed to use other peoples money and resources to break the law, yet when solutions like the above that prevent that exact thing yet allow legal use are made available, they bitch and moan about those as well.
Not only is UCI being extreamly over fair in this, they are still going out of their way, spending no doubt the same amount of money, to assure you CAN use p2p, legally or not, only making sure it wont interfear with others internet use.
If you want T3 speeds to the internet, shell out the $35,000 per month and get one to your house. This isnt DSL here where it may not be available.. for that kind of money the phone company will MAKE it available to you.
Dont want to spend that much just so you can leech movies and mp3s? Funny, nether do they.
Quoted: ~~~~~~~~~~~~~~~ OK - this is a troll - but could someone explain whether VPNs have any real uses apart from working around insecure servers which trust the network too much. ~~~~~~~~~~~~~~~
Sure. My company paid ARIN lots of money for a large block of IPs for its staff to use.
Well, they COULD pay another (granted not as large) chunk of money to get a C class over my DSL line at home, but it sure is nice to not waste my DSL providers IP space and use the ARIN alloacted space as it was intended, by setting up a tunnel between the two.
Thats just one example.
There are also times when its not possible to do any security above source IP ACLs.. A trollish comment on my part, but I would hate to put a windows machine running a service on the public internet. Im a UNIX admin, not a Windows admin.. I dont want to spend my time making sure my system is as secure as one can possibly make it only to find out there are still hundreds of bugs in their software that are explotable and unfixable.
To me for windows, source IP filtering is weak but exists and works for what it is.
Using secure services is great and all, and I fully aggree, but having two locked doors instead of just one is still a better choice.
If you came by and dropped a laptop in my lap for no reason nor did i ask nor was anything said between us, you lose the right to ask me for payment at a later date.
Noone even ever told me i had to pay to watch tv, short of owning a tv set.
How do i think that stuff gets paid for? Why should i think about it when it is not my concern. If they wanted money in exchange for it they should sell it like cable.
Then you get into the issue of 'they are transmitting their signal through me, so its not up to them to decide what happens with that signal any longer'
If i choose to allow public access to my network by placing a hub outside of my building with a sign stating "Free internet", why do you insist anyone that takes my offer is a thief?
Public WiFi is no different except for the link medium being RF instead of long strands of metal.
You are no doubt using slashdot for free because they said you are allowed to. Guess your a theif too huh.
Point B)
WiFi is radio.. The signal is just protons. It is no different really than light.
If you feel a WiFi signal can be owned, then I declair i own the color blue (And any frequency close to it.)
Anyone that sees the color blue without my express permission is now a theif.
Silly you say? I aggree. You cant own photons, you cant own RF spectrum, and you sure as Hell dont own any photons that are passing through my house and body right this moment.
If you dont want me to have your formatted protons, then keep them to yourself. The second they pass through me and or my house or even arguably anywhere i happen to be standing, those protons are free to be decoded in anyway I see fit.
Dont like it? Dont send those protons to me and i wont come after them.
Patching is modifying something that works without the patch.
Legally, one would assume only the creator of the work can actually distribute patches.
This is actually part of copyright law.
If i make something (a program) you cannot modify and redistribute it without the copyright holders permission.
If they recoded a program to do this from scratch (or atleast from an open code base) it would be fine.
Personally i dont see why apple doesnt let the patch exist, as it will be used by so few. But i do understand their logic.
Its similar to remixes or covers of songs. Without permission, its illegal, even though its done all the time practically (especially in the techno scene.)
As for patching an os by adding software, that simply doesnt happen. They are 100% seperate as defined by the API (usually provided by the OS) being the border between the two.
Now an actual OS patch is different yet again. That WOULD be illegal if you didnt have the permission of the OS copyright holders to do it (Yet again this is done all the time.)
The only 'bad' thing apple did was use the DMCA law as a threat instead of the correct copyright laws already in place for this sort of thing.
If you take microsofts OS loader for the xbox, and patch it to ignore somehow all the encryption features, and boot linux instead of their OS, you are violating the DMCA as it is written.
This is why no one is doing that, and they want to make their OWN software to run on the xbox.
If one made their own full distro of linux to run on the xbox, it will be fine. Same as if someone wrote a DVD player for the mac hardware, im sure that would be fine as well. That isnt the case here however.
Actually there are devices that have nothing to do with lucid dreaming that do this as well.
One 'trick' was to have a pair of goggles with a LED in each eye piece that flashes at a certain frequency. With your eyes closed (Just seeing the color change through your eyelids) your brain would try to match its frequency with that of the LEDs flashing.
This was used to slow the brain down to fall into deep sleeps, and also used to try and keep a person in the 'alpha wave' state, which is used for hypnosis as it is believed your very subjective in this state.
These methods dont require even consious knowledge by the person being effected to be useful, which is far from the case with lucid dreaming.
