Proxima Centauri Might Not Be the Closest Star To Earth 98

StartsWithABang writes The Alpha Centauri system consists of three stars, including Proxima Centauri, the closest star to Earth. But while main-sequence, hydrogen-burning stars are easy to find due to their visible light output, brown dwarfs — which only fuse the small amounts of deuterium they're born with — often emit no visible light at all, and can only be seen in the infrared. In 2013, WISE discovered a binary pair of brown dwarfs just 6.5 light years away, making them the third-closest star system to Earth, and leaving open the possibility that there may yet be brown dwarfs closer to us than any star, a question that it will take the James Webb Space Telescope to answer.

You mean you do exactly what the rest of the working world does with their laptop docking station?

I have an hp one at work, and a Lenovo one at home. Both have power and peripherals plugged in and I just drop my laptop into place for it all to spring to life.

Yes, a single wire is exactly what a docking station should be distilled down to. Really, screw wires.

for hd video, wifi is NO SUBSTITUTE for wired enet.

This.

And it's not necessarily the speed (bit rate) but the inherent instability and susceptibility to interference that really makes it unstable. If my wireless connection drops momentarily whilst I'm browsing /. I'm not going to notice, if it drops whilst streaming a HD video, chances are I'll notice (even buffering the video wont help too much).

If you want to send video over a network you use wires. If you're really serious or going long distances, you go straight to fibre.

No, it IS about bitrate. I'm getting ~580 Mbps over 802.11ac two rooms over right now, that's ten times the maximum bitrate of Blu-ray, or enough to buffer one at 10x. I would have to use a player that did't buffer at all, or suffer seconds of outage to have a problem.

Good AV playback is ALL about throughput, and has nothing to do with latency. Wifi isn't your problem, you're doing Wifi wrong.

If Wifi was't good enough for video, it absolutely would not be good enough for networked games, and then you're talking to a lot of people who don't have any problems...

try an mkv file; oftentimes it takes 2 or even 3 minutes before vlc (on win7 ultimate) begins to play, and that is with the very latest media bridge of ac to ac wireless (2 asus routers). this is as good as wireless gets for consumers and yet I have a several minute wait time.

why? I think the protocol sucks and there is a lot of seeking or indexing on some mkv's and with wifi latency, small packets take forever (when there are lots of them needed). plug into wired enet and the video plays almost instantly.

do a backup over the net? not likely! yes, I can. but its painful.

wireless also is quite insecure. a lot of people think its ok. many of us don't trust it.

so, anyone saying 'wired is dead for end stations' knows nothing about the vast number of use-cases where wifi falls flat on its arse.

(and try running nfs over wifi. good luck with that!)

That does't make any sense, what kind of video playback is sensitive to latency - at all? You're probably not getting the throughput you think you are supposed to be getting. Go back to the drawing board and fix your network man, Wifi is plenty fast for several HD streams.

WE are only THEORETICALLY capable of making something more intelligent than ourselves. Increasing relative intelligence might be an exponentially difficult task. It's obviously not easy. It may take the same amount of work * time for something more intelligent than us to make the same relative advancement. It may take MORE work * time to improve by the same amount.

From your own source:

There has been much debate of the allegedly poor performance of the bullet on target, especially the first-shot kill rate when the muzzle velocity of the firearms used and the downrange bullet deceleration do not achieve the minimally required terminal velocity of over 750 m/s (2,500 ft/s) at the target to cause fragmentation.

Not only are you wrong, you are so wrong that the round is actually criticized for not causing enough damage.

From what I was told in the service the round was designed to wound not to kill on purpose. If you wound someone, one of their comrades has to drag them back to cover. You thereby take two enemies out of the fight. But hell, what would the armorer know.

I think "designed to wound" is a reassuring way to say "technically not as lethal". We switched to smaller ammo for logistical reasons, to carry more ammo, and statistically less lethality is not a bad thing for the reason you mentioned, it's just not the real reason we switched to 5.56. Way I look at it is, without increasing the weight or cost, is there any obvious thing you can do to make a 5.56 nato round more lethal? The FMJ is for penetrating body armor, and only increases the chances of having exit wounds. So it was light, cheap, and "lethal enough" - not designed to be less lethal, in my opinion.

You can't vote with your wallet with free software. Unless you pay for it, and my wild guess is most people don't.

My understanding is that the military does have a completely isolated network for critical combat communication, but like any other global-scale organization, they're still probably reliant on the now-civilian internet because of the efficient communication it provides. For instance, communication with contractors, other countries' military forces, and so on are all vital for day to day operations, and probably can't be accomplished with a military-only system because of the sheer scale and scope it would require.

I just don't think it's as simple as saying "the military should not be on the internet". They either have to try to use it safely and securely, build a completely separate and parallel internet, or go without it. Granted, there's obviously a percentage of material that should always be air-gapped for maximum security, but the bulk of bureaucratic day to day communication and coordination only needs to be reasonably secure, and can probably safely live on the standard internet given reasonable precautions.

They have more than a few, and I seriously doubt very much reliance on the Internet because even mediumish sized businesses use private connections between themselves rather than some VPN over the public Internet for critical communications. I'm not saying they don't use the Internet, because you can get to it from their non-secure networks, but their private networks are comprehensive. Anything classified is on those air gapped networks.

Anyway, the purpose of our military is to defend US. They've got their own shit locked down better than most private organizations would tolerate. The way the Internet was designed, there isn't much the government can do for the rest of us without employing some sort of Great Firewall of China, or... TALK about the problems... like this journal.

You are right, "XYZ should not be on the Internet" is not the answer. Like abstinence in teenage sex-ed, it can't be THE answer, it's not good enough. The private sector is getting screwed right now, and even if it works for some of us, we can't keep shouting abstinence at the problem.

This. One thing I have never understood this sequence:

2. Court tosses out evidence.

So far so good. No qualms there with the court....

3. Cop is NOT charged with a crime, continues working

That never made any sense. If the search was illegal, he didn't have the authority to do it...so it was....by very definition....outside the parameters of his job. He was NOT acting as a police officer if he was conducting an illegal search.

In fact, if anything he was denying a person their civil rights under color of law....which is a felony. Why should he NOT be charged? Why should a prosecutor even be allowed to know about such an event and not bring up charges?

And no, I am in now way saying such evidence should be used.... I understand fruit of a poisined treee, I just don't understand allowing trees to be poisoned and hoping nobody notices next time.
