Not really, use your own stem cells to grow the tissue, grow a new heart/arm/etc., and transplant it. Transplant tech has advanced enormously in recent years.
Seriously, who torrents without using a blacklisting program like PeerBlock, anyway? Yes, I know it's not perfect, but it helps, and guess what? It can block ad servers, too! If I hadn't read about this here, they probably could have implemented the ads, and I wouldn't have known about it at all!
If you're more of the DIY type, like myself, I'd suggest building your own from scratch. Remus is an excellent choice for a high-availability environment. Admittedly, it's still a relatively young project, but as of Xen 4.2 (currently the unstable branch), it's been largely stable and easy to work with. You can even use DRBD as the storage backend (currently it's using a modified DRBD with a new "protocol D" synchronization method, but prot D is going to be integrated into the main DRBD branch as of DRBD 9, hopefully later this year).
Basically, you set up a normal Xen virtualization environment, but you mirror the configuration across two (or more) Xen nodes. You have two storage nodes sharing out virtual block devices (AoE is good if you'll have all the nodes on a single switch, iSCSI is good if you'll need to route over an IP network), one Xen node connects to one or more storage nodes, then DRBD running on each Xen node joins the block devices into a DRBD volume (I like to share out the whole disk/array of each node as a single block device, then create an LVM2 logical volume on each block device, and join the LVs together with DRBD). Xen then uses the DRBD volumes as virtual disks for the VMs. Once that's set up, you just configure remus to start when the VM starts, and it will checkpoint the current machine state between the two Xen nodes at a rate you specify. If one node goes down, the other picks up running the VM, without dropping a packet.
I've currently converted all our internal systems at work over to running on this cluster, and it works great. Highly recommend you take a look.
Well, apart from the fact that many of them are in the original packaging, and many of them are factory sealed (this is a huge boost to price for classics), you can't just take an average. For example, I'm currently selling my game collection (hate to do it, but it must be done before I move). I've got most of my games as complete boxed sets. Zelda A Link to the Past sold for $50, while Chrono Trigger sold for over $400 (and a mint sealed copy will net 7 or 8 grand)! Just looking at an average price per game treats all the games as interchangeable commodities, when in reality some games are more prized, more sought-after, and therefore more expensive than others, sometimes by a wide margin.
This story is worthy of note. As others have mentioned, this is the first beta release to use the Android native UI instead of xul. I can attest it is *dramatically* faster, night and day. The previous xul-based builds were largely unusable, taking 30 seconds just to start, even on my heavily oc'd phone. The new native UI builds run smoothly and fluidly. I've been using the native UI builds since they were first released as nightlies (currently on Firefox 15 nightly), and they're a big step forward.
That being said, these do have some big downsides. The native UI builds dropped support for things like text selection, copy/paste (can't copy what you can't select), and generally feel unpolished. Once all the features from the xul builds are available in the native ui builds, it'll be the best browser around, hands down. Until then, it's a nice tech demo from Mozilla.
Youtube is not a "public forum" as some people seem to think. Do I think it's bad policy for Google to handle the site in this matter, caving to corporate interests so easily with no defense of fair use? Absolutely. But Google doesn't "owe" you a forum for public expression, and has every right to manage their site as they see fit. Your videos may bring the traffic, but they own the servers and pay the bills, and therefore get to make the rules. Just because you shop at the local grocery store doesn't give you the right to drop a soapbox down in the produce department and make a speech.
So, say it with me now: It is not good to rely on Youtube as your sole means of publishing video on the internet! Granted, these guys were apparently smart in that regard, and had other venues for publishing their work. Many (possibly most) of Youtube's users are not smart in this regard. I would suspect that the majority of Youtube's users post their video on Youtube exclusively. Which means the longevity of your video relies exclusively on the whim of Google. This is a Bad Thing. I don't care if their slogan is "Don't Be Evil", anyone can have a slogan and not live up to it. If you vest everything in a single entity, that's a single point of failure. I would hope that on slashdot of all places, we'd have enough network admins to recognize the flaw in that thinking.
Or, to summarize your comments in the words of a very wise man, "Anyone even remotely capable of getting themselves elected to office should on no account be allowed to hold the position."
As a followup to my previous question, have you considered releasing Whisper Monitor as a standalone app for rooted devices, rather than integrating it exclusively with WhisperCore?
I really like the idea behind WhisperCore. The problem, as I see it, is that it's only available for two devices, and the Android source is updated regularly, making it difficult to keep WhisperCore up to date with the latest version of Android. Also, there are a wide variety of existing ROMs, each sporting its own array of features, but WhisperCore is the only one focusing on full-device encryption and a quality firewall interface. Given that security is becoming more critical on mobile devices, I would love to see WhisperCore's functionality integrated into every ROM. Have you given any consideration to integrating the WhisperCore project into an existing community such as CyanogenMod, or opening the source to build a community around WhisperCore? It would definitely help with making it available on more devices.
I've been using an OCZ Vertex 3 120GB since April. Throughout that time, their firmware releases have variously resolved certain bluescreen issues, while introducing others. Since installing 2.13, I have had major issues, and just last week was complaining that I would have to return the thing to OCZ and demand my money back. However, I installed 2.15 the day it was released, and all bluescreen issues have stopped.
Through all that, I have never lost any data. I was rather panicked at first (the drive won't show back up after one of these bluescreens until you cold boot the machine), but once I realized I could recover with a cold boot each time, I was merely annoyed. That being said, I knew going in that SSDs in general weren't that mature a product, and that issues like this crop up. I would never have placed important data on those drives, and would have kept a backup even if I had. Just as I never put any important data on an HDD without a backup (or at least a bit of RAID action).
Missing the point entirely. It's not an issue of being required to take cash or not, this law is a matter of being able to take cash or not. Businesses have always been able to reject cash for the purchase of goods and services (unless, as others have mentioned, the good or service is provided ahead of time on credit, thus creating a debt). Want to verify? Go to a gas station late at night with a jar of pennies and ask for a carton of smokes. Keep your eye on the attendant's middle finger.
The issue at hand is that this bill prohibits the use of cash in second-hand transactions. It requires all second-hand transactions to be completed via traceable means, and criminalizes the use of cash for second-hand transactions. This has all manner of negative implications, and if it stands the inevitable SCOTUS challenge, we should all be very worried.
Also, let's jog right past this "catching thieves" bullshit and get right down to what this is really about: unreported income and sales tax collection. You're not going to suddenly see an increase in the amount of recovered stolen property. You're going to see a massive increase in the number of visits from the IRS as well as state and local tax agencies, wanting to know why they didn't receive their protection money from the sale of that nice Persian rug you inherited, or the sales tax you "owe" them for hawking those rare NES games on eBay.
As far as driving an using a cellphone, most countries already make the concession that using a handsfree is okay, even though most studies show it to be just as dangerous as holding the phone. Having an active conversation is the distracting part.
Right, good point. We shouldn't ban cellphones, we should ban conversations. If the police see you talking to your passenger, or yelling at your kids in the back, why, they should pull you right over. Probably best if they beat you, too. Just to ensure you get the message.
Okay, see if you can follow me on this one: Forza is a game. A racing game. A game where you drive really, really fast. Much faster and on much more difficult tracks than you would encounter driving down a typical highway. And, unless he's invested in a wheel, a gamepad is not a steering wheel, R1 is not a clutch, and you don't shift with buttons. You can't compare a game with unrealistic controls where you're supposed to drive fast and take risks to driving in real life under normal circumstances (unless you're a formula one driver, in which case, yes, please get off your phone during the grand prix).
And my advice is: Please, for the love of all that is logical, get the hell off the road and stop driving! Seriously, you can't conflate the fact that you have some weird habit of dazing off and staring in to space with the notion that everyone does that. I don't. My friends don't. That's very odd, and not exactly a common trait amongst our fellow humans, so far as my powers of observation serve me.
That aside, its very good that you recognize this limitation you have. Its wonderful that you make appropriate choices in response. Which is, of course, exactly what I'm advocating. You took an objective assessment of your ability to drive and talk, and made the appropriate choice. Doesn't mean it applies to everyone, though. Hopefully you have enough sense to realize that "Well, if I can't do it, no one can." is not a reasonable argument.
As a quick aside, cops in general seem to be pretty shitty drivers. Had a couple incidents where cops who were simply talking to their partners nearly swerved in to me.
But, more to the point, it's a slippery slope issue. Eating in your car is also distracting. Do you solve it by banning drive-throughs? Reading in your car is a distraction. Do cops issue tickets if they see an atlas or a copy of the local newspaper on the seat when they pull you over? How about if you jotted down directions to where you're going, and a cop sees you check the paper to see if your exit is coming up? How about unruly kids in the back seat? Quite distracting, but you don't hear calls for kids to be anesthetized before getting in a car (although...).
Point is, if the government takes it upon themselves to enact a new rule, regulation, or prohibition for every danger in the world, then there's nothing you can do freely. There are laws against swerving dangerously from lane to lane in traffic. There are laws against running people over, or slamming blindly headlong into a telephone poll. Some people can multitask to the point where they can talk on the phone and drive. Some people need a hands-free device to achieve the same result. Some people (and I'm in this category) would rather stammer through a conversation and lose their train of thought because their primary focus is on driving, not talking. Some people just can't pull it off at all. You, like most statists, are proposing a one-size-fits-all solution to a problem that doesn't have one. At its core, what you suggest is no different than solving alcoholism or other forms of drug abuse through prohibition.
Exactly. I forget who said it, and I don't remember the exact wording, but I once read a very wise quote: "Evaluate any government proposal based not on the supposed benefit that will be imparted if administered properly, but by the harm inflicted if administered improperly."
And besides that, we're talking about a system where one group of people are making decisions about "appropriateness" for a huge mass of people. The notion of what is "adult" or "inappropriate" content varies from individual to individual, as does the notion of "mental preparedness". As with any system of censorship or ratings, those who disagree are left by the wayside (see: "This Film Is Not Yet Rated" for an excellent example using the MPAA).
Well, what about the probability that the system is being subsidized? Or, even if it is not (haven't checked), the salaries of the politicos who sat around thinking this up is being subsidized? Or the opportunity costs of ISPs wasting time and resources implementing this? Or the fact that such systems are already readily available for those who wish to purchase and utilize them, courtesy of market participants who saw a demand for this tech over a decade ago, and undertook all the initiative and risk of their own accord? Or the fact that those who had the prescience to identify and respond to that demand are now facing competition from a market participant who has been granted a distinct unfair advantage from a non-market-participant (the UK government), in the form of an official sanction requiring them to offer this? Or the fact that people will see this as an implicit endorsement from both their ISP and the government that this tech is 100% solid and foolproof? Or the fact that the vast majority of the users will never be aware that their web browsing is being censored by a bunch of kids in a basement?
That's the difference between a company "offering" a product or service, and the government "mandating" that they offer the product or service. In the first case, if you don't want it, don't use it, or even stop doing business with the company entirely. In the second case, walk away and you still pay for the "service". Use a competitor, and you still see the same impact. This is just taking a statist approach to an issue the market solved years ago.
I have had rather the opposite experience. I have a G2 as well, but mine is running Cyanogenmod 7 (one of the nightly builds, something like 220), and is overclocked to 1.5GHz (dynamic, on-demand governor). Despite that, even running at a straight 1.5GHz with no governor, all the latest builds still run slow as hell. And it's not CM, as my buddy has a G2 that is completely stock, not even rooted, and he gets the same performance. That goes for both the stable and the beta versions. I have yet to try the beta (alpha?) version which uses the native Android UI elements instead of XUL (which is insanely slow on Android thus far), but the builds I have tried were horrible. And, even if that version works wonderfully, the problem still remains that many addons rely on XUL for rendering their interfaces, so if they do away with XUL for the mobile version, that would mean addons would need to be re-tooled to eschew XUL (betting noscript uses XUL, from the looks of it). The only reason it is still installed on my phone is because I need to access an old sharepoint site for work (yeah, not happy about that myself, but that changes in two weeks!), and I can't use any of the other browsers I've tried (stock android, Opera, and Dolphin all fail, something about unsupported www-authenticate headers), but Firefox works.
Not all android is created equally. It varies from OEM to OEM, phone to phone, and of course there are all manner of highly-optimized custom builds like Cyanogenmod. Different default settings, different power consumption, different options for managing power consumption.

I for one welcome our new Cyborg Overlords!
Easy solution, slow down on the Diablo! Every high-end mouse I've destroyed this way, I can attribute to either D1 or D2.
The original Quake 1 actually REQUIRED an FPU coprocessor, as I recall. Never was happier to have a shiny new 486DX2!
