So is this a competitor to something like spreedlycore? I'm trying to find a recurring billing provider which can handle multiple merchant accounts, and the only thing close was spreedlycore, which handles the processing but none of the recurring functionality. Nobody seems to provide a recurring billing solution which supports multiple merchant accounts.
I don't have the specs, but 100Mbit operates at 31MHz. Remember, quad-twisted pair. So it is likely 1Gbit operates at ~300MHz.

Now, 10Gbit probably does operate with a period less than 1ns. (1 billionth of a second)

HP should buy Yahoo and then both companies can spiral down until their stock is low enough to be picked up by AOL
No, it is just the bootloader (same way the Android phones work), though MS could craft their signed bootloader to also verify the NT kernel (which would make sense).

The other problem is, in the original article that was published on this topic, that apparently the Linux/grub boot process will be changing so that the "kernel is part of the bootloader", so I think that adds to the complexity of the idea of signing either the bootloader or "the whole OS" (whatever that means anyway.

Hi all,

We just launched MySQLVault, a really easy, really secure way to automatically backup MySQL databases. We know a lot of web developers are focused on making their project awesome, and neglecting their database backups. There are dozens are places to sacrifice peace of mind when building something new, but now creating and tracking database backups doesn't have to be one of them.

We'd love to get your feedback in the comments-
Mailinator has a blog, at http://mailinator.blogspot.com - you should definitely read everything on there. Some things I recall reading:

- Mailinator is designed and written from the ground up to be efficient by someone who seems pretty good (Paul Tyma; on the implementation side, it's completely custom SMTP-to-web software keeping e-mail in compressed form in memory; on the design side, it "sheds load" far more aggressively than mail servers that are intended to be reliable, necessary for the constant DoS attacks);

- Mailinator has lots of imitators, but they tend to find out that the cost of running servers is higher than the ad revenue (see "efficient and cheap", mailinator processes a ridiculous amount of e-mail and recently added its second server because getting that much bandwidth to a single server was more expensive);

- As I understand, this is a hobby for Paul; he's not exactly getting rich (well, not from Mailinator anyway; he's on LinkedIn if you want an idea.)

I don't mean to discourage you, it sounds like a nice project. Just don't expect to get rich off it, or to be done tomorrow...
Um... is there any trace of neutrino bursts before that? Im not sure anyone bothered checking, since such a correlation would have been very hard to justify. A neutrino burst 4 years before a supernova... so what?

Could a physicist clarify whether neutrinos could travel at different speeds in vacuum like any 'normal' particle, or are 'fixed speed' like photons. We could well have had several waves with the bulk arriving at c-epsilon and no one bothering to check outside the expected time frame.

looks pretty cool to me, nice job
Back when I graduated college in 2002 into the tech bust and kept getting credit card offers to "transfer my balances at zero interest for six months", I took a bunch of zero-interest cash advances and put them into the ING savings account yielding 3-4% at the time. I did it for between 6 months and a year and netted a few hundred bucks before closing them all out. I wouldn't recommend it because a) it was more headache than it was worth to keep track of payments, and b) who knows what it did to my credit score. It was definitely an arb, but probably not operationally worth it...
Never mind them going bust in ten years, in a year or two they'll redesign part of the site again and lose it anyway.

For example, a while back they managed to lose parts of my profile (something to do with "pages" I think), and I used to be part of a group for my year at high school which, as far as I can tell, has silently vanished.
Let me get this off my chest: pointers are NOT hard. If every 16 year old with weed can talk about representation and meaning, every CompSci student can grok pointers.

Managing code with pointers is hard, but grasping the concept is easy.

Closures are far more confusing.

I didn't learn regular expressions for a very long time because people said they were hard. That was stupid. It took me a couple of days to get good at them.
I'm sure it depends crucially on the student.

The other thing to remember is that teachers speak to roomfuls of students at a time, not one student at a time. If you've got one student, then sure, you need never explicitly say that a particular concept is tricky. You can determine trickiness by trial-and-error: If the student gets confused at any point, explain again, but otherwise just keep going.

But with a whole roomful of people it's not as if you're going to fool them by avoiding the word "tricky": They're going to know when you cover something that is tricky, because half the audience will be confused, and the other half is then going to have to observe you explaining the tricky thing over and over again to the first half.
This is a really good example of an explanation that is correct in the basics, but almost completely incorrect and potentially dangerous when taken more in-depth.

Pointers are not ints. First off, pointers are unsigned data types. Also, on 32-bit systems, they're 32-bit unsigned longs, and on 64-bit systems, they're 64-bit unsigned long longs.

Both of those are incredibly important to understand, especially because the first can lead to very weird bugs with unsigned/signed comparisons or addition. I recently ran into a bug that involved that. 50% of the time, the program crashed with an incorrect memory address error. The other half, it worked completely fine. It turned out that we were casting a couple of pointers to signed values before doing some range checking. The cast converted them to hugely negative values, which broke the comparison check and sent us down a completely incorrect code path.

The second is important when dealing with structure and class allocation sizes.
Cool, it looks interesting. I put my email on the list. I hate hate hate the "sign up your friends now! The more you sign up, the earlier you get in!" thing that shows up after I do. I don't know anything about your site, so I'm not going to go recommend it to anyone.

I can see how the practice started; help spread the word. It just doesn't inspire confidence in me for a site where I'm going to end up posting all sorts of details of my life...

Still, I'll be interested to check it out myself once I can.
Some days ago I saw some people here saying that billions of dollars was wasted in LHC. I would like to know their opinion about new findings.

Hmm, not sure why you and others respond so negatively on my comment. I am merely pointing out that your original reply did not account for the usual 3-3.5% transaction fee on these 0% loans. Your only mention of such fee may be the "could borrow at %1 (on the "zero interest" plans)", which isn't anywhere close the 3-3.5% that I see. So taking that into account, "safe" investments like CDs will actually give negative return.

Meta: Not only did I read your whole initial parent post, I had also not mentioned a single word about "gold". So I am really intrigued by your negative tone and accusation of me jumping on the "anti-gold argument" bandwangon. Btw, I really enjoy reading your HN posts. But that doesn't prevent me from pointing out flaws in your logic. If my original reply sounded like an attack, then I guess I should be more careful in my wordings.
Perhaps I misinterpreted, but I think DenisM was talking about something completely different. He mentioned that because of a lack of density in the leading photons, the first piece of equipment missed the measurements while the second one picked it up.
That would a problem with the system they're measuring with, not at all to do with treating light as a single entity.

> but once the closed triads are more than a certain percentage the entire social network dies

I'm pretty sure you're misinterpreting a research paper that I'm familiar with. A common measure of network structure is the clustering coefficient, which is the ratio of triads to all possible triads. In real networks, the average clustering coefficient is generally orders of magnitude less than 1%.

Besides, the network is continually growing, and people generally continually meet new people. It's highly unlikely that the FB network is going to stagnate because "everyone already knows each other". At least not for another decade...

After much research... the concept is correct, although 'absorbed' and 'retransmitted' are not the right words to use.
http://en.wikipedia.org/wiki/Slow_light

"Light traveling within a medium is no longer a disturbance solely of the electromagnetic field, but rather a disturbance of the field and the positions and velocities of the charged particles (electrons) within the material. The motion of the electrons is determined by the field (due to the Lorentz force) but the field is determined by the positions and velocities of the electrons (due to Gauss' law and Ampere's law). The behavior of a disturbance of this combined electromagnetic-charge density field (i.e. light) is still determined by Maxwell's equations, but the solutions are complicated due to the intimate link between the medium and the field.
Understanding the behavior of light in a material is simplified by limiting the types of disturbances studied to sinusoidal functions of time. For these types of disturbances Maxwell's equations transform into algebraic equations and are easily solved. These special disturbances propagate through a material at a speed slower than c called the phase velocity."

As another commented pointed out, you're splitting hairs. The "speed" of light and how fast it is "moving" depends on how you define those terms. The second paragraph of the wikipedia speed of light article has it right "The speed at which light propagates through transparent materials" - which does change.

Relativity does not permit particles with mass to go the speed of light. However, the math works just fine with massive particles going faster than light. Further however, the effects are quite bizarre, even if well defined. You know how your physical intuition is basically useless when it comes to understanding relativity? It's even more useless when understanding what the math says about tachyons.

One of the more approachable discussions on the topic is actually http://www.theforce.net/swtc/hyperspace.html . Yes, I am aware of the context, but the author knows what he's talking about. http://www.mssl.ucl.ac.uk/~cjs2/
I'm not familiar with that experiment, but it doesn't sound to me like information traveled faster than the speed of light, which is really the important part of the speed of "light."

It seems more than any one specific CEO, the HP board has proven itself unfit to oversee the company. It's not incomprehensible that the best thing they could do for shareholder value and to protect their employees jobs would be breaking HP up and finding buyers. After all, aside from the earnings shortfalls all the big picture problems the market has with Apotheker have all been board approved.

It's worth noting that if this is true (my gut says it is), what you're measuring is successfulness of companies that go through YC (implies that the company is good enough to be accepted), not that of companies that apply. In any case, correlation != causation. This should be based on how you think YC would benefit you and your company, not potentially misleading statistics.
Ask HN: Where/How can I learn more about general webapp maintenance?
Particularly things like fault tolerance, speed, unit testing, code abstraction, etc.

I've been hacking away/making webapps for a while and although they're functional they aren't optimized for heavy use. Now that I'm working on a startup/production application, I've realized that general maintainance is a skill-set I really haven't perfected. Any good sources for these - especially related to Ruby/Rails? I'm working through code-complete/pragmatic programmer for general good code practice, but would love some other books/blogposts/anything on the matter.<p>Thanks so much!

Yeah, I was just wondering if you could filter based on wavelength or polarization, like photons. Isn't it really hard to "block" neutrinos coming from other directions though?
But that's why it's interesting, because it's possible that that's exactly what happened.
The best argument I see in all that text is that it can leave you with substandard work. The rest of it is a lot of corollaries to the idea that doing speculative work is not a good deal for a designer.

I think the idea in this guide is that substandard work is preferred to burning time or cash on professional design work. You aren't even sure you have a viable business. You should absolutely minimize time to iterate and cash spent in this scenario.

I'm all for supporting designers, doing business locally, and the importance of design. Unfortunately, sometimes people need things in the context of scare resources that don't permit the ideal choice.

Once there is a business...find a good designer and develop a great relationship.

Over Cat5e, it uses all 4 pairs and 2 bits per symbol, so it's only 125M symbols per second (per pair). I was thinking of fiber, which I think also uses 2 bits per symbol so it would need 500M symbols per second.

Aside from all other issues (sheer volume of APIs to port, people depending on it, etc.) it's hard to imagine using another language with Cocoa unless it also chose "theSame:kindOf:calling:convention:".

Objective-C just looks weird when you try to call it like you would a C function, because arguments are almost always intended to be preceded by names. So how would old APIs be invoked? They may work, but it'd be a very awkward transition.
Right, so if conservation of momentum is violated, then it's not a law of nature. That would be quite a discovery!

No one releases data in journals, at least not in astronomy. There are dedicated sites for this, e.g. http://archive.stsci.edu/

About the later date: I think it's reasonable that those that put together the proposal and thought up the project have a chance at getting their results out first. Otherwise, why would you go through the effort of planning and executing observations if you could just poach someone else's data as it comes down the pipe? Think of it as a 1-year patent on the research project.

The article seems a bit misinformed.

All of the UEFI systems I have encountered have native UEFI firmware in flash. On top of the UEFI environment, most shipping systems have a compatibility layer (CSM) that exposes a legacy BIOS emulation to allow traditional MBR-style booting. It is possible to load an EFI environment on top of a legacy BIOS (UEFI DUET), but that isn't usually how it is done.

There is no special bootloader; OS bootloaders are just UEFI applications in a specially-named path on each drive that the firmware finds and lists as boot options.

The mouse-driven GUI is a feature of some specific implementations, not part of UEFI itself.
Thanks for the excellent introduction to my next topic: An important function of programming education is to teach people which things other people often find difficult. Because intuition is not a reliable guide. And the secret to all effective communication -- which certainly includes programming, as well as writing and teaching -- is to write stuff that your audience can understand.

When the teacher says "this is tricky", consider the possibility that they aren't merely trying to motivate the students. It might just be a simple statement of fact: There's a significant population that doesn't get this at first glance, and you have to know that, regardless of whether you get it yourself or not.
By definition the laws of nature cannot be broken, only the "laws" we think nature has.

http://en.wikipedia.org/wiki/Neutrino#Speed

QUOTE

In the early 1980s, first measurements of neutrino speed were done using pulsed pion beams (produced by pulsed proton beams hitting a target). The pions decayed producing neutrinos, and the neutrino interactions observed within a time window in a detector at a distance were consistent with the speed of light. This measurement has been repeated using the MINOS detectors, which found the speed of 3 GeV neutrinos to be 1.000051(29) c. While the central value is higher than the speed of light, the uncertainty is great enough that it is very likely that the true velocity is not greater than the speed of light. This measurement set an upper bound on the mass of the muon neutrino of 50 MeV at 99% confidence.

/QUOTE

The value looks awfully like what we have in front of us today, but the uncertainty was too big to investigate further
