Comment: variable speed limit algorithms (Score 1) 400

by strangedays (#43408281) Attached to: Speeding Ticket Robots — Laws As Algorithms

The idea of using algorithms should be applied to the speed limit itself.

The concept of fixed limits is outdated given modern tech and borderline ludicrous on most roads.
An empty freeway that could safely permit speeds of 100 mph (in a modern vehicle,
with an experienced driver), whereas the exact same stretch of road might need a
limit of 25 mph on a snowy day or in a rainstorm (40), fog (20-50) etc.

Why not tie the "limit" to realistic parameters and then ding anyone breaking the variable speed ceiling displayed by the vehicle (or linked to the cruise control)?

I have often seen drivers on highways going at dangerous speeds in awful conditions,
but nonetheless technically "legal"; we need to drop this one speed fits all circumstances bs.

The other idiocy built into this study is blind and literal interpretation of law.
That may be convenient for the profit seeking highway robbers (you know what I mean),
but even in America that level of ass-hattery is fairly rare (but mindless legal stuff is happening much too often)

It's really disturbing to see the massive disconnect between this kind of academic study and any kind of reality.

Ok... academic faculty dweebs, here are some real world algorithms you should go figure out:

a. How to implement speed algorithms for safe but variable limits
b A study that shows the de-facto algorithm in use for cop pay and grade review cycles as related to ticketing stats (gotta be a function in there somewheres).
c. Develop for the FBI an algorithm that alerts the district attorney of "municipal highway robbery" scams, on the vast stretches of "permanent construction" zones, where no one ever really works but lots of tickets happen near monthly quota time...

In many locations politicians of dubious ethics and room temperature intelligence, have passed laws
to make it illegal and/or impossible to build a community wifi.

I realize there are some technicalities and costs to amortize, but really! so what?
Compared to expecting kids to hang out in fast food joints so they can do homework, or look for a job online,
how can communities really believe that some shared wifi is a bad thing?

It's mostly the "asleep at the wheel" voters fault, that's us folks...

These messed up laws should be reversed at the Federal and/or State level immediately and
funding provided to make community wifi and broadband happen.
Plus some serious people tasked and responsible to make sure it actually does and report progress frequently, this is already way overdue.

We have to choose between allowing our leaders to force us into either:
a third world style information access (no access)
or having a well educated and employed society.

Patriotism, basic community spirit, ethics, makes this seem like a no brainer to me.

IMHO, there can be no excuses, no apologistas, no rationalizations that justify continuing a monopoly at the expense of the USA's future generations.

The way I see it, this is also part of the rich corporations strategy to dumb down America, and we need to make an effort to buy/bribe the politicians into changing their "screw the people, if it helps me get re-elected" laws.

The Europeans have it defined correctly, internet access is now a basic right, a need.

Suggested action: Let your political critters know that voting for this kind of dumb stuff, is not acceptable, if they ever want your vote.

+ - The Struggles of Developing StarCraft->

Submitted by Anonymous Coward
An anonymous reader writes "Patrick Wyatt led production efforts for several of Blizzard Entertainment's early games, including Warcraft 1 and 2 and StarCraft. Wyatt has just published an in-depth look at the development of StarCraft, highlighting many of the problems the team encountered, and several of the hacks they came to regret later. Quoting: 'Given all the issues working against the team, you might think it was hard to identify a single large source of bugs, but based on my experiences the biggest problems in StarCraft related to the use of doubly-linked linked lists. Linked lists were used extensively in the engine to track units with shared behavior. With twice the number of units of its predecessor — StarCraft had a maximum of 1600, up from 800 in Warcraft 2 — it became essential to optimize the search for units of specific types by keeping them linked together in lists. ... All of these lists were doubly-linked to make it possible to add and remove elements from the list in constant time — O(1) — without the necessity to traverse the list looking for the element to remove — O(N). Unfortunately, each list was “hand-maintained” — there were no shared functions to link and unlink elements from these lists; programmers just manually inlined the link and unlink behavior anywhere it was required. And hand-rolled code is far more error-prone than simply using a routine that’s already been debugged. ... So the game would blow up all the time. All the time.'"

Hugh Pickens writes
Hugh Pickens writes writes "Isaac Asimov's idea that the movements of masses of people can be predicted may not be quite so fictional after all as Markus Hammonds writes that researchers at the University of Edinburgh have constructed a statistical dynamic model that makes predictions on levels of violence in conflicts such as the recent war in Afghanistan. Their methodology is to analyze how a conflict unfolds by treating outbreaks of violence the way other researchers model the spread of infectious diseases modeling complex underlying processes in conflicts, such as diffusion, relocation, heterogeneous escalation, and volatility (PDF). The researchers first tested the performance of their methods on a WikiLeaks release which contained over 75,000 military logs by the USA military, describing events which occurred between the beginning of 2004 and the end of 2009 that provided a high temporal and spatial resolution description of the Afghan war in that period. "Remarkably, based entirely on written reports between 2004 and 2009, they were able to predict with impressive accuracy, what events would occur in 2010," writes Hammonds. "Even accounting for sudden changes, like the dramatic increase of US forces in Afghanistan in 2010, the predictions remained accurate. Evidently, events will continue unabated despite any large military offensives which may be taking place." In Baghlan province, for instance, the simulation predicted a 128 percent increase in armed opposition group activity from 2009 to 2010. The Afghanistan NGO Safety Office, a nonprofit group dedicated to protecting aid workers in dangerous parts of the world, reported that activity in Baghlan rose by 120 percent from 100 incidents in 2009 to 222 incidents in 2010. "This kind of work offers some hope in resolving serious conflicts as quickly as possible", concludes Hammonds. "Whatever your feelings on it, the ability to predict violence in conflict situations the same way meteorologists predict the weather has some potentially very useful possibilities.""

+ - Hurricane Windspeed at Landfall Foretell Economic Losses ->

Submitted by sciencehabit
sciencehabit (1205606) writes "A hurricane's final price tag depends on a lot of factors. But after taking population growth, property values in afflicted regions, and inflation into account, it’s possible to roughly estimate the economic losses for a particular storm based on a single aspect of the storm: the wind speed when the storm first makes landfall. For every 1 meter per second increase in a storm's wind speed at landfall, damage costs rise by about 5%. Using the new method, the estimated economic costs of Hurricane Isaac, whose peak winds measured about 130 kilometers per hour when it made landfall as a Category 1 storm in Louisiana last week (image taken 28 August), are about $1.2 billion."

NASA has done a great job, they got us all to this point.
Now, NASA's strategy and role needs to change, their funding must change, it's way overdue, they know it, we know it.

To their great credit, they are doing it, they are adapting and embracing the change; it's hard for them, an era is ending.

Space is big, the opportunities are literally infinite, but science budgets are always way too small, efficiency matters.

So we cut the well known tech and commercially viable elements loose from the taxpayers dollar.

Let whatever NASA morphs into, fund and guide the basic research and science, spend more on that, less on vehicles.
That's the stuff NASA does well, the right stuff, basic research, initial exploration, the stuff that shareholders and businessmen looking at next quarters results typically do poorly.

NASA exploration vehicles and science packages can buy rides on whatever commercial launchers they need, at the going rate.
We buy planes and ships, trains and trucks from commercial vendors, shipyards, and aviation companies, so whats different?

Clear out the cold war, legacy buck rogers, pointy spaceship with fins thinking, and move onto real space-drives, profitable commercialization and real sustainable colonization.

As for the shuttle.... well I am as jingoistic as the next fella, I admire their bravery just getting into the thing (i think i would be terrified, but i'd also go...)
However... continually launching the mass of 7 people crammed into a vehicle that has twice failed, killing the entire crew...

Empirically, it seems obvious that the efficient way to do successful science in space is, small fast vehicles, robotics and AI's; humans should only boldly go... when their is a proven and compelling reason to do so, and little expectation of them making it back alive if anything fails.
Spirit and Opportunity did more, for far less, for far longer... than any human crew could likely have done.

That's the kind of research I want my tax-money to fund. Efficient hard science.

So lets figure out how to mine and move asteroids, survive indefinitely in deep space, harvest the oort cloud, build CHON Food factories, go where the resources are available, easy pickings...

If we want to get off this unguided mud-ball, we must adapt to new strategies as necessary, however hard they may be.

Comment: What has been changed to prevent re-occurrance ? (Score 1) 449

I am not a pilot. I am a regular commercial airline passenger, a so called "frequent flyer", sometimes internationally; all of which often involves taking long night flights over ocean and into undisclosed/random weather.

I like the flying itself, but for the last few years I have avoided casual air travel for two reasons :
1. the airlines for their miserable attitude to passenger comfort and schedules
2. airport/security for their poor facilities, ludicrous security theater, cumulative irradiation and civil rights violations.

Reading this discussion, and writing simply as a passenger, I conclude that the equipment on planes and the capabilities of a regular airline crew are inadequate to prevent a modern airliner from simply flying into the ocean, given what seems to be a very common set of conditions. I appreciate that this is an interim report, fair enough, but are we simply hoping it does not happen again?

I now have a new reason to avoid flying - a credible, common, and yet apparently unmitigated risk:
3. A generic airliner (it's just another passenger vehicle to me), experiencing common high altitude flight conditions, with a nominal/average crew, may kill everyone on board, because the flight control protocols cause the crew to fly it into the ocean.

Is there any clear and credible statement by the airline industry as to what they are doing to prevent this from simply happening again? What have they changed so that more people wont die, the next time this set of circumstances occur ?

I am guessing many people will want to tell me I am wrong to be concerned; if so, that's a good thing, but please explain why, in simple terms a frequent flyer can rationally believe. IMHO, "The next crew won't do the same things..." seems a bit too optimistic and basically unprovable to me...

I accept your point that for some, faith and religion is an irresistible temptation; like a drug, it partially suppresses natural fears and loneliness.

Those that take advantage of human weakness to sell faith, the pushers of religion, the clergy, are the real evildoers in most human cultures.

When history records the worst abuses of the 21'st century it will not be the predatory sexual acts of priests that are viewed as the most horrible of religions crimes against humanity (terrible though they are), but rather the ongoing mental abuses, indoctrination and outright deceptions forced onto defenseless young minds, by many religious organizations.
"suffer the little children to come unto me" is both a mandated and abusive practice, and a terribly irony.
Amazingly, and a real cause for hope, many children survive and recover from these wicked mental abuses, and become Atheists, like myself.

IMHO, Pascal's wager proceeds from the, unstated and unproven premise, that a god will both judge, and require a person to have belief (in that specific deity presumably).

That the premise is unstated, shows either a lack of logical rigor, or an intent to deceive on behalf of Pascal, which detracts from his argument.

That all the arguments premises are also unproven and unprovable, (which Pascal himself acknowledges of his stated premises) makes the entire argument worthless, as the proposition is unfounded.

Extraordinary claims (such as the existence of a god) require extraordinary proof, which Pascal and all religious believers decline to provide.

Another version might claim that a malicious (and arguably insane) deity, may well choose to send all "true believers" the faithful, martyrs, straight to some Dantean hell
simply for having faith, for holding an unconditional belief, for not demanding better proof prior to committing to a "belief".

Dante's hell, is of course a fate no Human could ever possibly deserve, no matter how evil or misguided their lives.

Mea Culpa, you got me, I used a red herring to make my point, as entertainingly and in as few words as possible.

Your logic is sound, there is no reason to subscribe to any specific rationale of judgment by a deity, because there is no deity.

I chose this particularly bloody herring, as a small homage to Socrates.

When he was sentenced to death, Socrates chose to die rather than give up Philosophy, because "The unexamined life is not worth living." I paraphrased (and partially disguised it) as 'choosing' or 'thinking for yourself'

Socrates considered philosophical self examination one of the "highest goods", and paid for that choice with his own blood.

Being a moral atheist is a total win win, compared to being a mere Theist.

Version 1:

Dead Atheist: Oh!, um hi God..., didn't think you existed, oops!

Deity: No problem, it's not like I left any useful clues... Welcome to my heaven.

Dead Atheist: Nice... How come I qualify?

Deity: Because you were a moral and ethical being, because you lived by a code of ethics; you understood that love was the right thing to do even in a universe that you had good reason to believe was completely and utterly godless. You were moral because you chose to be, not because you "believed" in some silly magic book; or were too scared, or weak minded, to think for yourself.
You chose to do the right thing, even when you did not have to; you lived by a moral and honorable code, not by some mythical manifesto of terrorism and fear...

Dead Atheist: So what happens to all the myriad god followers, "believers", the Theists, martyrs, crusaders, suicide bombers, terrorists, etc?

Deity: Tricky one that! They are not really worth anything much, because they never thought for themselves ethically speaking... What do you suggest?
Anyway, no hurry, they can wait outside indefinitely while you decide what to do with them. Welcome to heaven!, go pick yourself out some virgins...
Etc...

Version 2:

Dead Atheist: Hello, Anyone There...! (nothing, nada, zip, zilch, silence, nope...)
Dead Atheist: Thought So! (vanishes in a sudden total existence failure)

So........

Looks like a Win Win to me!
