Comment Why not concerntrate development on primary batter (Score 1) 171

Maybe it's not necessarily easier to develop higher density primary batteries as supposed to rechargeable ones, but it might not be a bad idea to approach density problem from a couple different approaches. Once batteries can approach 2-3 kwh/kg, 3-4 banks of say 10kg battery packs should be fairly easy to swap, negating charging problems. 30-40 kg battery packs should give similar range to gas burning cars, and they should be fairly easy to build out distribution network using existing gas stations. Of course efficient recycling also should be worked out.

Comment Re:Batteries (Score 1) 904

Why are people so fixated on rechargeable batteries? However much batteries improve, the charging times for batteries would be substantially longer than refueling any way. Why not put more substantial effort into perfecting non rechargeable metal air batteries and have people just swap batteries at depots. It would require a least amount of investment into infrastructure since existing gas stations can simply add storage to distribute batteries, and the most expensive component-battery recycling plants- can be constructed as needed at strategic locations without having to be numerous. The battery cells would be standardized cell size that all cars can use, and cars can have small rechargeable batteries to recapture energy. Metal-air batteries have the energy density to make this a workable solution making electric vehicles for most people. I just don't see why this option isn't explored more.

Who exactly? All the parties of the original war? I mean, technically speaking, is the US, UK, and South Korea at war with China, the Soviet Union, and North Korea, then?

(Genuine curiosity of the techincal details.)

The armistice is between UN (represented US) and NK with China. US would be automatically involved if the armistice was broken by treaty between SK and US. China would automatically be involved also though I'd imagine they'd be in a very uncomfortable position.

Comment Could someone explain fast/breeder reactors? (Score 1) 309

I've read up quite a bit on the fast reactor, so I understand quite a bit on the potential benefits at least in layman terms, but not being a nuclear engineer, I have no clue how well those potentials translates in practical terms.I believe they can be made much safer eventually, but I don't think I understand enough to see if they can really produce less long lived high level waste with cost factored in. Is it possible for them to transmute most of the long lived waste without affecting the economy of power generation too negatively.

Also, I think I understand most of the technical challenges associated with fast type reactors, and it seems to me that most of the challenges should be able to overcome with more trials. Yet, there really aren't production level trials besides BN-600/800 and some research reactors in India. Is it mostly political problems or is there still significant engineering challenges that prevents larger scale trials? And finally, how promising is the BN-600 design really? Is BN-800 off to pretty good start?

I wonder nuclear energy's chance to shine might be sailing away. I have to imagine it'd take another 10-20 years before fast/breeder reactors are ready to replace fossil fuel reactors in large scale, and solar energy probably would be ready for large scale generation by then.

Only violent criminals make real crimes then? You don't think monetary damage do not affect people's lives in general? I'm glad to hear you don't concern yourself over monetary necessities, but I believe most people do. I appreciate that you consider rapists and murderers worse criminals than embezzlers and fraudsters, and I imagine most people do. Yet, the gravity of their crimes comes from the fact that they affect millions of peoples lives. Most of the victims probably would get on with their lives, albeit with worse qualities of lives. Some of them even might scoff at their losses and like to throw blanket statements while acting superior to people around. Still, there will be few that would be devastated and pillaged because their livelihood would had been destroyed. Sure, you can view them as unworthy if you like, but please do a service for all of us and take time to explain the fleeting nature of materialism to them in person. Perhaps you can enlighten them before their desperation drives them to suicide or even violent crimes.

Comment Re:Intel already realized where their market is (Score 2) 113

Medfield was likely just an exercise of sort for Intel. I'm guessing they're going for a big splash with Airmont in 2014 since they're finally pulling up the Atom die size schedule along with the Core line. I'm not sure what Silvermont is going to be. If paired with Haswell graphics, Intel might be able to compete with ARM seriously, but I'm guessing they''re going to concentrate on Airmont design to create something that has a definite edge over ARM. Apple might be a wild card partner with Intel. They seem to have a cozy enough relation already, and Apple probably want to find a way to end their relation with Samsung somehow.

Comment I'd welcome immortality (Score 1) 813

if I get to have health along with it of course. I don't know if my mind would be capable of processing infinite time span, but I'd rather see what's going to happen tomorrow and live it even if I have to forget the past. Immortality would be a selfish and ultimately a dead-end for for the specie as a whole since never reducing population obviously isn't sustainable. Still, even if I have to become a last remaining human in the universe, I would still choose immortality if it's an option. I just want to know.

Comment Re:Tape Solution (Score 1) 326

I always find it surprising that whenever the subject of backup comes up here, there're always only a one or two posts that suggest tapes only to be ignored. In the present day, tapes are still the best archival backup method readily available. Sure, the entry cost is rather high, but I think it would be worth it in your case since your data pool is only getting larger. Keeping backup copies on HDDs are convenient, but I would keep a minimum of 4 copies, at least a pair in 2 different sites since HDDs always have a chance of failure when powered. Cloud is only an option if you have no issues with bandwidth. Even without bandwidth issue, I still don't feel completely comfortable subjecting my data to risks entirely out of my control. Here's what I do personally. All my archival data is backed up on LTO Worm tapes, and I have most of those data on RAID-z2 for availability. Every online data is backed up incrementally daily on a separate array, and I do weekly full backup on tapes on monthly rotation along with month full backup on yearly rotation. Everything that needs permanent storage goes to WORM. While I won't claim my backup strategy is the best for everyone, but I go to bed each night satisfied with the level of safety with my data personally.

The AOL crowd showed up in the mid 90's and essentially destroyed the original internet culture. This was not an improvement.

Well, AOL was merely the beginning of what was probably inevitable any way. Besides, Usenet(where AOL crowd's presence were really felt) is only a small part of the internet, and I'd say the internet is overall more useful place now because of its universal access. That said, I do miss the old Usenet. There just isn't anything quite like it, and I don't think there can ever be anything like it again. /. probably comes closest but not quite.

Now immagine you are locked up between four concrete walls with a toilet and bed. The first few days (Week at the very most) will probably be nice and relaxing. Afterwards I will just simply be going insane from boredom..

I don't disagree that solitary confinement would suck, but for for me, it'd be because of the confinement part. Some people just does not have a problem with boredom part. Growing up as an only child, I have never really felt boredom much less any sense of loneliness. I'm not some weird anti social shut in either. I've always had friends and now a wife with a child. I don't think my social skill is terribly different from most people. I just never had a need to rely on it.

Comment Re:How else does one back up 20TB of personal data (Score 1) 312

The main advantage for me is the inherent stability of tape medium over hard disks especially as an archival medium. Hard drives always have a chance for failure whenever you plug them in. Tapes are safer in that regard. It's not a significant advantage for home users, but I find it a nice luxury to have duplicate data both in always available medium (RAID6) and in archival medium (LTO3).

Comment LTO3 isn't really all that expensive any more (Score 1) 414

If you buy used at least. I bought a 16 tape LTO3 library and 20 LTO 3 tapes for around $500 used on ebay about a year ago. It might be even cheaper now. And if you don't mind changing tapes every hour or so, LTO3 stand alone drive can be had for $200. Also, if you're only going to deal with only 1TB worth of data for a while, LTO2 is more than enough, and a used LTO2 autoloader can be had for under $200. Hard drives are never a proper backup solution. The data can be lost(without paying a few thousands for recovery at least) any time you plug in the hard drive. The tape solution is just so much more stable as a data storage platform, I'd say you look into getting used LTO2 autoloader at least. They really shouldn't cost more than a couple of hard drives.
