if by free you mean "free and open source", they're not "unexploitable". The only thing that is IMHO guarateed is the chances for a quick fix in the case of an exploit are higher!
As the chronic gambler should know that the casino wins on the long run.
The thief knows what would happen if he's caught.
He's point, I think, is not about less or more secure. either is as likly to incroporate bugs a the other. It is about the chances of finding a vulnerability and the time it takes to fix it.
With open source, If you happen (or know someone) find a vulnerability chancesa re you can fix it right a way, report/submit a patch. As for a closed source, all you can do is report and wait (slashdot is full of articles about that).
if there's a choice between blaming someone for a problem and avoiding the problem, avoiding (when possible) is always the winner strategy.
I didn't know, I removed everything gnome 2 years ago. I switched full time to kde (always had both installed). If and when kde will require that too, I'll switch to something else (enlightenment may be, since it was my 1st choice years ago).
to each his own:).
Isaid gentoo b/c, I use it (I don't even remember since when), still no systemd forced down my throat (KDE4 seems to not depend heavily on it, and frankly don't care for the desktop env, the only utility it has -for me- is keeping multiple windows open on the same screen, -heavy terminal user-)
Well, he did say "switched to arch from fedora", Linux user was a fair assumption, hence gentoo (which if I remember correctly can run a *BSD kernel).
As to why would he wants to? I don't know (and I don't care). It was a simple suggestion.
45% of what and 15% of what?
I have 50$/day I loose 15% (7.5$), there go my lunch for the day. I have $1B I loose 45% ($450M), it's a lot of monney but I still have $550M to spend.
Taxe brackets may need some rearangement, but I doubt he was talking about your relativeley modest income!
howcome adding a resistor will worsen efficiency? adding the resistor will drop the current so will the power (since the voltage is the same). (genuine question there)
You could try to do a clean shutdown, but then, say, some cleanup code tries to allocate a string to write persistent data to a database, fails, and writes garbage into the database instead.
clean/graceful crash is just that. If an operation you depend on fails, try to recover or exit in a clean fashion.
In most cases, 'just crash' is the better choice.
in production systems it never is (or at least the very last resort).
Also making assumptions may lead to something like this : http://en.wikipedia.org/wiki/Ariane_5#Notable_launches
try doin somthing like this :
....
i = some_calculation function_that_might_return_0();
return res = 1000/i;
what would happen if it = 0, and that piece of code is part of some control software for a say a rocket or a plain.
ok, I'm no expert but I had few courses in programing.
and I remeber that if you did somthing like this you'd get a very bad grade:
int *p;
p = malloc (sizeof (int));
*p = 1;
free (p);
the reason was : what would happen if malloc fails. The answer : possibly all hell will break loose. The lesson was don't assume, always check!!!
in C++/JAVA it's is even easier: there's that thing called try.. catch
even paid for apps can and will gather info.
Take cable TV fort instance.. paid for (a hefty sum sometimes) and still there's almost as much ads as content! paying doesn't magically aleviate or rsolve th problem. it is as you said " because people (generally) are basically lazy, stupid, greedy and short sighted." that we are in this situation !

The engine is mechanically connected to the wheels, so whatever the engine produces propels the vehicle. There cannot be any "extra" energy.
The system can produce more energy by pressing the gas pedal further, using more gas.
the net ouput at the drive shaft (
while my car is idling car if the AC compressor goes on I notice that the engine loses few rpm. On the road, I notice also that I need to press harder on the pedal to get the same speed (engine RPM). An alternator on a car can generate 50 amps at 12 volts (may be more but that's ~2hp at max capacity , since nothing is free is needs at least that amount of mechanical energy), what can this generate in term of electrolysis, how much fuel is consumed to generate that much energy.
the point is not to replenish the full tank, merely extending it. If burning the whole tanks yields a few grams (to move the vehicle few meters) it's not worth it but if it can produce say 1/4 of a tank that 1/4 max distance with a tank gained.
the electricity can come from different sources too, heat (muffler, engine block, which can help cool it -if it is a combustion- ) wind (small wind turbine, at highway speed ), braking (divert energy to shorten breaking distance, like engine braking with manual transmissions or some other contraption)... etc.
the question is, how much does the engine produce, how much is needed to propel the vehicle. ICE do it relatively well (alternator and much of the pumps -mechanical and electrical) but at the expense of MPG. may be by adding something to the breaks it would be better
all in all it looks like a differential eq which has a solution... now is it practical or not I can't say (I'm no expert in chemistry).
well, diverting some of the energy to power the alternator, it doesn't have to be a perpetual motion (which is supposedly impossible). just a way of extending, if a tank will run out in X hours or X miles if left alone without additional production, it'll run out in Y hours/ Y miles (where Y >> X), at that point you'll have to fill it in some way or an other (just like with ICE cars, gas stop). or what you said:)
The problem with fuel cells however is the energy chain. Electrolysis is not a good way to create hydrogen because most countries, or at least the US cannot keep up with electricity demands (at least currently) should cars and other products be switched over. The primary way hydrogen is manufactured now, if my data is still current is through natural gas. And therefore this doesn't get us away from traditional carbon issues. The potential of hydrogen is possibly good intermediate storage, or at least another vector of energy research we can pursue.
how about creating it in the care using some kind of alternator to generate the electric current needed to for the hydrolysis?
not even you can decrypt the message once encrypted with the other person's public key. The only key capable of that is the private key of the recepiant.
#4: TV/Internet Equipment Fees:
Overblown. The break-even point on buying your own equipment is ~2-4 years of ownership, assuming you never have a problem.
modems (DSL, not DOCSIS: see below)? if not free rental it's a rippoff (new 50-70$ used 5-20$, they last years).
TV boxes? well, may be. But the thing is if you want this or that tv/cable internet provider, you need their box,
you can buy your own (except if you bought it used from an ex customer of the same company) sot they charge what ever the hell they can get away with,
especially when they control usually a very large proportion of the market.

there is (sun, wind, heat ). but bot enough apparently.
but what would be the point of having more electricity in a car that do no require more.

I meant electrolysis not hydro... , and it was a simple honest question, no point.

it can be obtained from water (Hydrolysis) no?

a large(sessor) camera is not a requirement for that. doable with a compact point and shoot (not as noticiable nor beatiful but still).
