Irony? Or makes perfect sense.
Cute-looking-samanta-pics
It sounds to me like it's an incremental improvement on existing technique, which the researchers are justifiably excited about, and through the Mighty Power of Mass-Market Science Journalism (TM) it becomes something that has never been done before, instead of it "merely" being done better than ever before. Photons have definitely been "teleported" before, as have individual atoms [1]. Though I scare-quote the word because it doesn't really precisely correspond to what people think of when they hear the term.

It's interesting, but it's not a breakthrough, nor does it herald any sort of advance in anything resembling Star Trek transporters, though to its credit I think this is the first Mass Market Science Journalism (TM) article on quantum teleportation I've seen that managed to avoid that faulty comparison, so points for that I guess.

[1]: http://www.livescience.com/7647-teleportation-milestone-achi... (which I would note fails the Star Trek test)
This is not FTL no, that's still impossible and if they'd done -that- this would be a big deal indeed.

What this allows is simply transmitting "quantum information" from one place to another with any reliability at all, by packing it with classical information that helps accomplish that (being the macro-object/light packet).

http://en.wikipedia.org/wiki/No-teleportation_theorem explains why transmission of quantum information is difficult.

http://en.wikipedia.org/wiki/No-communication_theorem explains why quantum effects do not enable FTL transfer of classical information.
Minimum round trip time between San Francisco and Tokyo is about 60ms due to the speed of light, which means in practice FPS games are unplayable across the ocean.

If they manage to implement this shit, we'll be able to have FPS games hosted anywhere in the world!
Should be enough to ban all software patents. Apparently, the older generation knew how to hack too.
And this is why science is hard to report on
Quantum optics is outside my realm of expertise; to be honest my eyes kind of glaze over whenever these guys give a talk. The real life applications of this are not really teleportation in the "beam me up sense" but more along the lines of encryption.

If your transmission is based on quantum entangled photon states, it is physically impossible to eavesdrop without giving yourself away, since the act of eavesdropping 'collapses the quantum superposition' (like when you open the box with Schrodingers cat). They've actually already rolled out systems based on this technology in various places in the world, but there is a lot of work to improve bandwidth and so forth.

I won't say too much more as I'm well outside the field and will probably garble it.
Hanscom Field is a bit smaller than DCA. A Cirrus is a bit smaller than a 737 (or whatever the planes landing at DCA were.) DCA is, oddly enough, immediately adjacent to Washington D.C. and Hanscom is hundreds of miles from D.C.

If the sleeping controllers were at Hanscom rather than DCA, this situation wouldn't have blown up nearly as far.

ouch... unity's kinda a good idea, but totally immature atm.

Panic has had SFTP built into Transmit since 1998, and a full SSH terminal in Coda since 2007. So Prompt did not come out of nowhere, they have quite a bit of experience in this problem space.

Still if you are in an industry that demands careful vetting of security, I certainly agree one should not jump on a new SSH client right away.
This technology can not be used for faster-than-light communication. If it could, this would orders of magnitude larger news than it is.

Can someone please explain what the term "teleport" mean here? I'm not getting why this is an amazing scientific breakthrough (but I'd love to learn why it is).

If it doesn't mean information travelling instantaneously or faster than light, then did the reporter (or the scientist) put the word "teleport" in the title just so it's attention grabbing?!
Once while driving down to the Oregon coast, I was very surprised to be driving through a rural area and suddenly see a 747 parked near the highway, at what appeared to be a very small airfield. Now that I know what the place is, I definitely won't visit the coast again without going to the Evergreen Aviation & Space Museum.

If you're not into water slides, maybe some of these exhibits at the museum next door will interest you:

- Spruce Goose

- Mercury Space Capsule

- NASA X-38

- SR-71 Blackbird
Can anyone explain what quantum teleportation is? Wikipedia does not help, aside from assuring me that it is not what I thought it was:

Quantum teleportation, or entanglement-assisted teleportation, is a process by which a qubit (the basic unit of quantum information) can be transmitted exactly (in principle) from one location to another, without the qubit being transmitted through the intervening space. It is useful for quantum communication and computation. It does not transport the system itself, nor does it allow communication of information at superluminal (faster than light) speed. Neither does it concern rearranging the particles of a macroscopic object to copy the form of another object.
Heh, I wish. Unfortunately, the word teleport here does not mean what everybody immediately thinks. Otherwise, this would mean sooo much more than lower latency gaming.
Overall, pretty interesting. A lot of those are definitely usability bugs. I wish someone would do a comparison between mac os x, windows, ubuntu with the same tasks to see how they stacked up against each other.

However:

5/11 participants (P2, P3, P5, P9, P10, P11) crashed Unity during their hour of testing. And towards the end of her test, P11 opened a zombie quicklist that stayed on top of everything and didn't respond to clicks.

This ubuntu release is shaping up to be pulseaudio 2.0. I know everyone will just say "use LTS", but somehow debian testing manages to be both more up to date and more stable than normal ubuntu releases. I'm not sure why canonical can't at least match that.

Best Fire Pits For Your Home
A better word for non-quantum-physicists would be "transport" here. It's very difficult to move quantum bits from one place to another at all. The light beam is used to increase the reliability of that process.

This doesn't affect how -classical- information is transmitted or make it any better. It makes -quantum- information transmission reliable, which is actually pretty significant. This should allow for quantum computers of larger sizes than the super-tiny ones that have been created so far to actually work.

http://en.wikipedia.org/wiki/No-teleportation_theorem (why it is difficult to transmit quantum information)

http://en.wikipedia.org/wiki/Quantum_teleportation (what is being done in this experiment) What the breakthrough is is a way to do quantum telportation reliably -and- quickly (which had both been done before)

For maximum safety from registrar screwing up, don't put your main domain name in the glue records either, just ns1.example.com.

But, it appears to be in the registrar's best interest to not encourage users to run their own DNS server -- as the article points out, that contributes to their lockin.
Correct. Python 1991 (20 years ago) & PHP 1995 (16 years ago).
I've used both and performance-wise my team didn't see any drastic differences. We switched to EC2 mostly because of RightScale (which now also runs over top of RackSpace). It's not cheap, but running on RightScale has made server maintenance and scaling a breeze for us. If this is a pain on your team, I recommend them.
If true, it's remarkable that we exist today at all.
A userscript could easily achieve this, no? just extend the width of .wk-today and .tg-col-today. I guess the agenda view would be harder. I'll try this as soon as I get home.
I wonder: 11 people seems like a rather small sample size; does Canonical typically do any testing with larger samples?

I'm surprised that only 5/10 people tried to open another Firefox window by clicking the launcher icon. Personally, I think clicking the launcher icon not opening a new window is silly, but that's because I'm used to Windows 7 and not OSX.
That I did get. Not only did I not get a discussion going,(not for the points--but for the discussion) but at least two people were honestly confused by the post. What I have yet to learn is how deeply to comment if I should comment at all. I'd really like to contribute. But its clear that I would do well to stick to the reading unless its really, really in my field.

Thanks for your help.

The speed limit of the universe isn't just some hypothesis waiting to be disproven. It can't be broken. It's impossible.
Similar argument could be used against staying local: are your engineers as capable at data retention as Google's? What if your in-house people screw it up? Will you have some remedy that isn't available to you if Google had screwed it up?
Have they built prototype receptors to harness this solar magnetic energy yet? It seemed pretty theoretical still. Or did I miss something?
Honestly, I posted a bit impulsively as the first read of your comment sparked my post, but upon review - you were not as rejecting to the idea as I had originally thought... so, my apologies, though I do stand by my points for others who may not think tweets are ads.

Cheers.

I am currently working with seven people in different timezones and I needed to see when they would answer my emails or when I could chat with them.

Although Amy did offer a tool to solve this problem (http://everytimezone.com/), I found it too confusing for my simple brain.

This is how is born the Remote Team Work Hours tool! (I am competing with Microsoft on the longest product name, any suggestion?).

I would love to hear your feedback and how this tool could be improved to be more useful.

I'd really just like to know why your framework reinvents the wheel for nearly every aspect of the application stack? Looking at the code even thus far, I don't see how Paraglide or Paragon improves on any aspect already offered by the largest frameworks Zend Framework, Symfony and Lithium, which already have documentation, encourage new contributions and follow best practices within their respective paradigms.

Why not contribute to an existing framework? Your efforts will be better received and more widely appreciated.

The absolute last thing the PHP community needs is another framework.
If you really like philosophy, dig into it as deeply as you can. Some really excellent programmers were philosophy majors, and benefit continually from the training in rigorous thinking and clarity of expression that studying philosophy teaches you as you get into it further.
One Thing I Really Hate About the JVM

Nice overviews of the history of Lua and how it has and is being used in the Game industry with lots of hints based on hard won experience in game production.

Pluto got mentioned twice as being a strong solution for Lua serialization (think saved games): http://lua-users.org/wiki/PlutoLibrary

LuaPlus is a Lua distribution that has superior C++ integration, and other enhancements for i18n, performance and memory optimization: http://luaplus.org/

One of the key features that makes Lua such a strong candidate for embedding in games is its native support for coroutines which is a real boon for game AI.

There's more to "day-to-day operations" than backups.

The reality is that Google is much less likely to damage or lose your data than you are, but it's always good to keep extra copies around locally. This is important for many reasons, like access when either Google or your whole net connection is unavailable, and more flexibility with the data.
They entangled a q-bit with a packet of light, and then sent it from one place to another (presumably using fiber optic or something), without breaking entanglement.

This is important because it gets you the ability to route quantum information to different places.

Presumably a quantum bus in a computer or a quantum fiber-optic line.

I can see the marketing pamphlets now!
If this were a brand new framework, then maybe it would be a waste of my time, unless I had more compelling reasons. However, I started building my framework a few years ago and have just been making incremental updates here and there. Friends and coworkers have started to use it over time, and people like it. I've been told to publicize it over the last 3-6 months, but haven't gotten around to it.

My framework is minimalist and gets the job done. I'm a big fan of minimalism and I don't like that some modern frameworks are bloated and have something like hundreds of thousands of lines of code, as opposed to just a few thousand, and that includes components outside the core, like helpers.

Paragon has more work in it than Paraglide. Paragon can support multiple different backends with the same code, just different drivers. I know this exists in other PHP ORM frameworks now, but not a few years ago (not saying mine was the first, it just wasn't as widespread). Also, Paragon integrates cleanly with Memcache so the developer doesn't have to deal with cache and uncache logic.

Hope this clears things up!

The Socratic method can be frustrating with one child, because when she doesn't get it, she really doesn't get it, and it takes a lot of questioning to lead her down the right path again. Sometimes you just want to bang your head against the wall when you ask the simplest leading question and she gets it wrong. At least with a group most of the kids will get those questions right.

I think my wife and I use that teaching method quite naturally. I'm never inclined to just give our children the answer; they only learn when they arrive at the answer themselves.

I just read the quote that everyone is printing (although haven't seen the full statement).

GSA certified the Google Apps Premier environment as FISMA compliant in July of 2010. Google Apps for Government uses the Google Apps Premier infrastructure, but adds additional controls in order to meet requirements requested by specific government agencies. The original FISMA certification remains intact while GSA works with Google to review the additional controls to update the existing July 2010 FISMA certification.

It's unclear to me what they're saying with respect to Google Apps for Gov. Are they saying that it is FISMA certified as of today? Or are they saying that its pending recert after the review, but the original Google Apps Premiere is still certified?

It sounds like they're saying its not certified w/ new controls, but they don't have to a full certification process on it as its built on a certified product -- they only need to check the deltas. In which case the DOJ and MS are technically correct.

Or are they saying that if you make a small change that requires recert, you keep you certification as the review takes place and they can revoke cert if they determine there's a problem. I can't believe that would be the case, because it would require pulling down a deployment, which can be expensive.

It would be nice if they simply said, "Google Apps for Gov" is certified. We're doing additional certs on new functionality, but the new functionality can be deployed as the cert is checked. But it's the US gov't, this is probably as clear as they get.
Does he mention what happened to Rasmus?
Yes, of course supply and demand factor into the cost. Your argument above is using the theory of marginal utility (http://en.wikipedia.org/wiki/Marginal_utility) the labor theory of value was replaced by that http://en.wikipedia.org/wiki/Labor_theory_of_value
Documentation is key! Browsing the code on github gives me an icky feeling - no docblocks :o - but I imagine I'd feel the same about my own preferred frameworks. Looking forward to a good read :)
I guess that really wasn't the point. The intention was to find out the usability bugs in Unity.
Jakob Nielsen does suggest [1] that only 5 users will get you about 80% of the problems in your software, and 15 will get you damn-near-everything. So 11 is pretty good.

I have to disagree pretty vehemently.

Are you running 11.04 beta2? I've been running it for months now and I LOVE Unity. I installed on my wife's machine, and while she doesn't love it (she really doesn't care one way or another about computers etc etc) she appreciates it in many ways. Though, the best way I can describe my wife's interaction with Unity is she gets less annoyed with it than she does/did with our iMac. True story.

Unity quickly became part of my workflow and improved it greatly. Super-W, Super-# are awesome, Dash is good (not great) and I like that something is built-in to the system that allows me to do basic searching etc (I hope this improves, but initial pass is really quite good). My workflow feels more fluid and solid w/ Unity, and I feel more comfortable, and hence, more productive than when I was in OSX just a short while ago.

And stability is something that is hard for me to gauge as I've been running since January on my test machine and beta1 on my main machine without too much problem. I get some quirks here and there, but nothing drastic. I'm running it on three machines: a mac mini, a lenovo t61p and a lenovo t60p. The t60p is the least responsive (naturally) and that is mostly b/c the ATI drivers are not as good as Nvidia's. The mini and t61p are nvidia and after installing those drivers everything works great.

And to compare, I used a Gnome3 live CD for several days trying to decide if I wanted to install something with Gnome3 (most likely Ubuntu w/ Gnome3 if that was the case, tbh...Ubuntu packaging makes it worth it alone) and while I think Gnome3 is a good release, it can't really compare to Unity. I like where Gnome3 is going, but I don't see it as something that directly competes with Unity at the moment.

I think Unity has a ways to go, but if you compare Unity in 11.04 to, say, OSX when it first came out...by god man, Unity is lightyears ahead in usability an consistency. People tend to forget how rough OSX was for a couple of releases. Apple has their act together now, but it took some time. And I LOVE something like Unity existing on Linux and being FOSS...pushing boundaries...
Amigas of the day ran Mac software much faster than the mac did - they shared processor architecture (68000), so there was no need to translate code, and unlike the macs of the day, it had hardware acceleration for 2D graphics ("blitter") and sound (paula, denise or angus - can't remember which).

The amiga was a technology marvel when it came out - it could do background 14-bit stereo sample playing in 1985 (PC got there around '92), and true useful multitasking with 128K (PC got there around '94, but not with so little memory).

Graphics wise, it was on par with the arcade machines of the era - the PC got there in '93 or so.

Technically, it was superior. And then the business part was miserably run, and the tech side stagnated (that is, was also miserably run).
Why are people assuming that 'teleportation' means instantaneous travel?

To me, teleporting has always meant transferring the information that describes an object to another location, where the object is reproduced. This transfer of information occurs via light/radio waves or similar.
Hmmm... that's a good question...

Personally, I hope the village-renters have to agree that any current tourists retain access to any normally-public venues. Private is debatable.

If you had asked me 3 years ago to write PHP code to do anything, I would have asked you what PHP was. 6 months after the fact - and 6 months into using CakePHP - and I was definitely a useful PHP developer. I can say the same for those I used CakePHP as a model for.

As far as only knowing the framework, you are preaching to the choir. I regularly give support to people in IRC who forget you can actually write regular PHP code - Reflection class, closures, etc. - in CakePHP. Sometimes even OOP.

A framework gives you structure. Good developers go back and fill in the blanks on the language. Bad developers don't need a framework to be bad, they would give you horrible code samples regardless.
PHP is a complicated templating language ;)
He shouldn't hate the JVM, he should hate his lame system. Rule #1 is "Never trust students' code".

One of the strengths of threads is that they don't have strong protection. If he wants runtime safety like that he should learn what a process is.
Wouldn't a process-based architecture be more suited to what he's doing (running arbitrary code)? It'd give you the chance to lock it down tightly if you wished within the OS itself, on top of the JVM security.
slightly pedantic, but Gnome 3 is the intended successor of Gnome 2 (not its predecessor)
