In this case I think we see an illustration of the fact that the notion of a particle as a mathematical point in space - something with zero dimensions - is an abstraction; an approximation that works well enough because we can't in that much detail any way, and it makes the equations so much easier.

All that we ever really measure after all is interactions (not exactly the same as 'forces' but 'force' is the macroscopic equivalent.) Both the notion of particles as either something with zero dimensions, something with many dimensions, or perturbations in some theoretical 'field' is an abstraction.

Take the leptons such as the electrons. In our observations we frequently take several interaction measurements of 'an electron' that together happen to be consistent with a mathematical description of a 'distinct thing' but that doesnt make it so - all we actually witness are the interactions, and in actuality its the interactions many times removed that we are witnessing but thats another topic.

'Electron' is just a label to help describe some interactions that we observe. There is a difference between knowing somethings name and knowing what that somethings is. The most truthful statement that can be made is that the universe appears to preserve some quantities in between interactions. We have given names to these quantities (charge, mass, spin, momentum, ...) as well as names to the sets of these quantities (electron, up quark, ..) that appear to be linked in some fashion.

Richard Feynman cared about the interactions. He didnt bother with the notions of what particles actually are, or even what the quantities preserved actually are (or why they are preserved.). In one interview he notes, when talking about inertia, that there is a difference between knowing something and knowing the name of something. We have a word for a phenomenon we observe called inertia, but we havent a clue why it is so.

Particles are just labels.

Subject says it all:

Don't allow a once-five-star app to rest on its laurels forever. After six months if you haven't inspired anyone new to rate you, your rating should decay to zero. Not only would this tend to favor new apps over old ones, but it would also effectively punish those developers who "fire and forget" app after app after app with zero support or updates for old apps.

Money transfers are also a lot easier to manage [...] Why use this horribly complicated system

Horribly complicated?
Credit: Swipe card, sign the receipt, done.
Debit : Swipe card, enter your PIN, done.

I don't see how you can call the latter process "a lot easier", unless you have some sort of crippling hand disease that makes signing things difficult.

Why use this horribly complicated system if you can transfer money from your savings to the shop anywhere?

This likely varies by country, but in the US, you have a $50 maximum liability, period, for fraudulent credit card swipes (as in, someone physically has your card), and $0 for non-swiped transactions.

For debit cards, you have that $50 liability only if you notify the bank within two days of the fraudulent charges. That shoots up to $500 if you take more than two days but less than 60 days, and you have full liability if you take over 60 days to report it.

Thanks, but I'll go through all the trouble of signing a receipt in exchange for not paying out-of-pocket to redecorate some thief's apartment just because I had two busy days in two consecutive months and didn't have the time to go over my statement with a fine-toothed comb.

It still is. The physics of oil cooling is good, but it's not practical in terms of the effort it takes to both administer and replace/upgrade hardware. If left in an enclosed system like power transformer, sure. But then again, those are mainly "set it and forget it" devices rarely touched once in place.

Reverse discrimination. Jesse Jackson is putting race, not skill level, as the priority imputes to employ more blacks. In his world view, society must bend over backwards to cater to the African American.

Hey Jesse!!! Yeah you. They don't want to be an Uncle Tom. The idea of "white" culture (a culture of being educated and the further pursuit thereof) is what may of the blacks are against. Those that you represent value ignorance over everything else. For them, they derive power through victimization; and the liberal society is all to willing to go along with the coddle-fication of victimization attitude!

Comment: PCI DSS Standards (Score 2) 305

That design tells me that you need to put a PCI-compliant hardware firewall between the POS and its associated DB server, and the rest of the internal network. And you also need to have a firewall logger that is actually looked at daily, plus you need to do vulnerability scans both internally and externally. A Windows firewall is not sufficient and won't meet PCI DSS requirements in any event, ever, and isn't going to provide any benefit if the firewall between the POS network and the rest of the store/enterprise is in place.

Any device that processes, carries, or stores ANY credit/debit card data that isn't encrypted *must* be behind a firewall that only permits it to send traffic to specific hosts that are necessary for the functioning of the system, and even then only on the bare minimum number of ports, and almost all inbound traffic is denied as well.

Real solution is for the people to stop believing that politics is a career. Have people serve us for a few terms the get rid of them. Have our government come from workers, businessmen and entrepreneurs. Let them serve for a bit then go back to their real career.

As long as we allow this behavior it will continue. Also if you are going to murder people ... Murder people who vote based on letters of TV commercials.

If you are not going to take the time to truly understand an issue keep your fucking opinion to yourself and stay the fuck out of the voting booth.

If you are *truly* cynical and/or paranoid, one would almost think that GM set up the lawsuit to further enshrine precedent. Not hard to imagine GM lawyers getting a whiff that the RIAA might be contemplating action, so they find some poor underfunded schmucks to sue them first so they can smack them down hard and discourage well-funded schmucks.

In the USA you can get a low-end tablet for under $60 easy. In many urban areas you can get 768Kbps internet for under $20/month. If your carrier allows previous-generation modems (some don't) you can get a used modem dirt cheap.

If Mom or Dad has a smart phone that acts like a hotspot you don't even need a separate internet - just make sure the kids don't use up all of your gigabytes (most low-end cell data plans in America are metered or they throttle to "2G" speed after a certan amount of usage each month).

So a client of mine uses Comcast Business as their ISP. I drove on-site to configure a SonicWALL. Their modem was in bridge mode with the only option of turning into "pseudo bridge mode" (something like a DMZ). Also, the modem wasn't yet provisioned for their assigned static IP pool. Only Tier 1 answers the phone. If you require Tier 2, a call-back within 24 period IS THE ONLY OPTION! And most of the Tier 1 guys don't know how to do anything other than provision modem, basic reboot troubleshooting, and scheduling a truck roll for physical coax connectivity problems. Or put it another way, I can't schedule in advance (proactively) to setup a business gateway firewall. You have to wait and be reactive, then drive X amount of mile on-site all while the customer is left offline with a business that can't function (IE losing money!!!). But it gets better; Tier 2 will configure the modem and reboot the unit without calling first. Epic fail!

Problem 1: I can't get a modem that will drop down to true bridge mode

Problem 2: Business class support is inharently reactive and not proactive with regards to scheduling downtime.

Problem 3: Tier support of all levels wildly range in competency.

Problem 4: -fill in the blank because I'm sure I missed something here-
