In many places, such as in Pennsylvania, often the state troopers will give a +15 MPH leeway... so a driver going 79 MPH in 65 MPH zone would likely *not* get a ticket. Personally, I stick with 5 to 10 MPH over the speed limit max, but I know many people who swear by the +15 MPH rule.
On a related note, in some states, such as Pennsylvania, some speed detection methods, in particular Vascar (timing), has a +10 MPH leeway... so again, even in lower speed limit zones, such as a 25, one often can drive nearly 15 MPH over that and likely not get a ticket...
Of course, if the driver admits speeding even 1 mile over than that above stated leeway likely won't matter... also, some states have "absolute" speed limits - there is no leeway so to speak... something a driver should be aware of when driving through some small towns that rely on speeding tickets for revenue; PA outlawed radar for most local police decades ago for just that reason and thus many local PA towns are forced to use Vascar instead.
Often an officer will try to get the driver to admit to speeding and then play nice cop by offering to write a ticket for only going x over the limit, etc.
Digressed, but there really is a "secret" speed limit in most places, though many drivers quickly figure it out over time...
I'd imagine similar is true for high-bandwidth users... many of them have figured out how far they can push it.
All that jet fuel rapidly burned off, far before the 1 and 2 towers collapsed.
What most likely caused, according to experts, the 1 and 2 towers to collapse was structure failure of the connections of floor struts due to the heat of furnishings, etc burning (note again, the jet fuel rapidly burned off in the first few moments) and heating the steel, which was poorly insulated...
The floor struts warped, floor connections to the curtain wall failed, causing floors to fall onto the floor below them - now that at first wouldn't be a problem, but once multiple floors fell upon each other, the load limit of the remaining floors below them would rapidly be exceeded; run-away chain reaction leading to total building collapse.
In short, there was no redundency of the floors themselves - using no columns came with a huge tradeoff - large columnless spaces for more usable office space, but risk of major disaster if more than 2 floors callapsed upon each other...
WTC 1 & 2 were fantastic structures for sure, but were built on the cheap - what reportly made matters worse on 9-11... was the use of drywall instead of concrete in some portions of the core, and less / thinner steel utilized in the core and floor / curtain wall connections than what should have been for that type of structure.
Some may be interpret his comment about NY WTC 1 & 2 as over the top, but he's right on... they too were an example "value engineering", to borrow a phrase from above, while having redundency for their outside shells, did NOT for the floor slabs themselves; each floor was designed to around 3x expected load, but that's of little to no help in a "pancaking" scenerio in a tower that had well over 100 floors...
Also, some of the other "value" decisions made during WTC 1 & 2 construction are laughable by today's standards, such as using drywall instead of concrete in various parts of the core structure. Contrast that with the Empire state building, which despite being somewhat smaller, contains over double the steel, considerable amounts of concrete, substantial fire-proofing, and are built with a box frame contruction, which is highly redundent.
There are numerous instances in which a person will win a big jackpot and then shortly afterwards win another, even possibly same exact, one... even on the same machine - and many employees who have worked on the casino floor will attest to observing such happenings.

Either there is more to the story or that casino is operated by idiots because an experienced casino manager is well aware of basic statistics; at minimum from mere observation alone.
The near misses are not "programmed" per se, but rather, as some other posters have pointed out, is due to uneven distribution of the virtual reel symbols*
* a visual symbol on modern slots is assigned to one or typically numerous virtual reel positions (ie. 0 to 255 or whatever); typically "blank" is assigned the vast majority on many machines with the other higher paying symbols being assigned few to as little as one specific number only. The distribution is often different for each of the reels (typically 3) on the machine.
Do some googling on "virtual reel positions" and similar for a better, more detailed explaination of distributions and near misses...
In short, the near misses are NOT programmed - they don't need to be... what you are seeing is statistics at work due to the uneven distribution of symbols on the virtual reels.
"Card Present" and "Card Not Present" transactions are treated very diffently. The latter is what the article is discussing - and yes, the merchant is most always the one liable for bogus charges.
On a related note, there are other *per-transaction* costs of such bogus on-line "test" transactions mentioned in the article that many people aren't aware of, such as:
These are IN ADDITION to the discount fees (ie. ~3% or so) of the dollar amount of sales.
Even if later the transaction is voided / refunded, the merchant typically still pays the above per-transaction fees regardless.
And even worse, depending on the merchant processor, the discount fees may not be refunded either; upon refund it may even be charged again! Doing "auth-only" and hand verifying sales before submitting the batch can help mitigate such refund costs, but is often labor intensive.
One nasty scenerio for an on-line merchant is a carder running thousands of card "tests" on their small business / charity website... the per-transaction auth fees alone can easily run into many hundreds, or even thousands of dollars.
Large merchants have more favorable merchant agreements / absorb such costs with no problems; often have advanced fraud screening in place to throttle such extraneous transactions. The small merchants, such as charities, are those who really suffer from such card "tests".
One should be careful what they wish for... the next school shooter will likely skip the Post Office and go post it on MySpace and YouTube... how does one control that?

I won't be surprised if there's a follow-up posted here in a few months about Google Maps and/or other similar services being strong-armed by government/industry (likely under the guise of "protecting homeland security") into censoring environmental damaged areas from public view.
Below is a quick copy and paste from one of my posts on DNForum regarding IDNs... I own some IDNs and believe they have much potential, but there are still many unanswered questions...
I'm running into a lot of issues that many IDN folks aren't discussing - probably because they've not consider them...
Various issues / threats / questions:
?? The existance of numerous diverse dialects, even totally different languages, etc in the same country... it's among the reasons that English dominates in some areas; some natives, even if they can understand a particular dialect, will sometimes speak a totally non-native language, such as English, instead to avoid risk of offending the other party. One can't assume one language dominates an entire region - languages can also overlap many areas... it's one of the reasons some are pushing for language / culture based TLDs, such as.CAT (among the dumbest ideas ever, but that's another discussion for the.CAT thread running here on DNF).
?? An IDN that contains western european characters that very close matches a non IDN... ie. cafe.com verses café.com... what happens? Will the IDN be highlighted / blocked by default?... likely an easy UDRP target?... introduction of a new IDN specific dispute procedure? -perhaps there already is one?
?? Trademark issues... ie. an IDN that is similar / exact to a trademark in another country... less obvious, what about an IDN that translates to that of a trademarked word / phrase? -I believe there's a thread discussing such an issue now on one of the other boards here.
?? language variants (more applicable to asian languages, etc) related issues... how good / stable are the various language variant tables?
?? what happens when a language variant table changes? -how are conflicts handled?
?? what happens if a character variant (an IDN [IDL package] technically can comprise multiple character variants [code points]) is released?... does the current registrant get first dibs?... even if yes, it may not be quite that simple if a character variant occurs in numerous permutations.
?? What happens if a reserved character variant is changed to a preferred character variant? - while such a change would have little to no effect on affected IDNs (IDL packages), it could result in the appearance of some IDNs changing... probably not a biggie compared to some other issues, but one to be aware of.
?? How reliable, especially for those in languages with numerous character variants, will IDN domain resolution be?... IDN resolution depends on much client-side APIs.
?? How well will IDN resolution APIs be regulated... I can easily envision scenerios in which a web browser and/or other applications (email, IM, etc) implement resolution differently... ie. adding and/or ignoring one or more valid language associations for a particular IDN / converting similar-looking western european characters to standard A-Z characters, etc. A related concern is language table management - I'm a little hazy on if the tables will be internally stored by each app or remotely loaded for each session, etc.
Rambling on, but there are a lot of things that one needs to be aware of with IDNs.

The biggest flaw with DRM is the ease of which digital content can be copied... once one has a "good" copy, it's basically game over.
While it's true the entertainment industry could require players to validate all played content (ie. using reference frames) in real-time to a remote server, such an approach is likely to ultimately fail for numerous technical and practical reasons.

In addition, in both categories of products, many of them embed a unique identifier in their output.

Anyways, there's no need to print a fake boarding pass when one can use self check-in and some fake id / bogus credit card to print a real boarding pass.
On a related note, most, if not all, of the 9-11 terrorists had valid id - in fact, at least one of them was actually flagged as being on a watch-list, and yet was still allowed on...
Before someone says that couldn't happen today, think again... there were news reports the other day explaining how the U.S. government purposedly leaves some names off the watchlist the airlines use - so if that flagged 9-11 terrorist(s) were to try boarding today, it's possible he wouldn't even be flagged at all because the U.S. government doesn't trust the airlines.
In a nutshell, airline security has little to do with safety and instead mostly about monitoring and controlling the populace.
