But if he was not insulted by the possibly insulting comment then he could say that he was insulted by the police by them arresting the original insulter?

Well, currently there is about ~1.4Billion USD in value in the bitcoin network.. Well, maybe quite a bit less but even having more than $100M should say something about the usage..

Bitcoin's are as much for illegal things as normal cash is, the only difference is that it's not government-controlled..
Some things that it would be perfect for:

- Micro-transactions for buying services on the internet.
- Simple way to transfer money all over the world.
- Generic way to buy things instead of VISA/Mastercard etc. No or very small transaction-fees. This also makes the retailers free of subscriptions to the banks for the card-terminals.
- Check https://bitpay.com/ for one currently available service. But they require a transaction-fee, but also converts bitcoins back to your local currency at the time of the sale.

The thing is right now that it has not grown big that's why there have been quite of flux on the exchange, and liquidity is just also something that reflects on how big it is..... But saying that it's only or mostly for illegal things then you are completely wrong..

And i don't know myself if bitcoin is the way to go.. But the concept of it is very promising.

There already exists bitcoin escrow services.... Perfect way to protect against both bad sellers and buyers... Another benefit would be that it would cut out PayPal that are just screwing and locking down peoples accounts for no good reason and then keeping the money themselves.

About that the corrupt and criminally rich (how ever could someone be a criminal for having too much money btw?) would screw society over even more i would like to make you aware that bitcoin's are non-inflatable.. Ie no government can print more money and make your current savings disappear.. No government can go into your bank-account and take any money, like they did in Greece..

I think that having a non-controlled currency would be beneficial to society as a whole.... Not sure if bitcoin is good enough, but it's ideas looks promising.

Actually, bitcoin does not give you the anonymity that you think.. http://anonymity-in-bitcoin.blogspot.se/2011/07/bitcoin-is-not-anonymous.html

And since someone is going to want the bitcoins in a usable currency, since you cannot really buy much with it currently, it can be traced to a broker that made a payout to a person.

Well... They can probably never agree on anything so no new regulations will be introduced :)

To start with, not everyone are native English speakers, and when tired it can be hard to build sentences for some of us.... I can even sometimes surprise myself when reading it the day after..

Have only been working for about 15 years in the field so i think i can say i do have some experience ... Buy of course nobody could be better than you, and any one else that contradicts you must be wrong...

To design a system that is physically safe (factory robots and similar things) are quite easy to make safe... To start with it's both a combination of software and the physical setup.. If the thing is designed the correct way it can be extremely easy to write code making safe in the physical world... There are actually recommended ways you should follow when designing for physical security..

Designing software for safety and/or graceful-failures is not hard.. It's on about on the same level as the rest of the system. If you design things in the correct way to begin with you don't have to hack together a safety system into it but can, with ease, implement a monitoring solution.

Just for your information... Graceful failures is in use quite allot in the world... The simplest example of it is transactions in databases where you can do a rollback if something goes wrong.. .

And you seem to have a problem with understanding that sometimes people can have problems with their non-native language... The point i was making still got made, even if the sentence was screwed up...
Main reasons why software is written in assembler. Resource issues / requirement for exact timing on limited hardware / some cpu's did not have any higher language available at the time this thing was built.
If the problem was resources ie memory or available cpu-cycles, get a faster cpu and/or more memory.
If the problem was timing issues on limited hardware then the hardware should be redesigned. Example would be slave cpu's that would take care of the timing-critical tasks and a main controller with some type of RTOS on it.
If the problem was that the platform did not have any higher-level language available then the it should be switched out.

The largest problem with systems written in assembler is that they become extremely hard to do code-review's on and when adding new features it's very hard to spot problematic areas. I have spent many hours reading assembly of old implementations just to figure out what they do, and since no one had touched it for 5 years no local knowledge existed. Just getting a understanding of the code-flow can be hell, and many developers do not write nice code or the system was written under time-pressure and that resulted in badly written code.

And from looking at your comment-history it looks like all you can do is criticize other people without actually saying anything so my recommendation to you is to move out of your parents basement and get a life. (Just jumping to conclusions the same way as you seem to do in many of your posts..)

It does work and does help out quite a bit...

If you take 2 products that does the same thing. The product-lifetime is ~3 years and new firmware is required every 3 months for it to continue working.
Product 1 have security features X,Y,Z and use obfuscation to make it extremely hard to actually do reverse-engineering on.
Product 2 have security features X,Y,Z.
(X,Y,Z is the same code implemented on both products)

What product do you think will be first to be attacked? If you make the reverse-engineering for the product hard enough so it will take at least 6 month's it will effectively make the product non-interesting for most attackers... Also adding things that make attacks non-scalable or requires soldering and other physical modifications of the product removes quite a bit of incentive too...

There is a big difference in security and security..... Consumer-products do usually require much less security and instead require mitigation of successful attacks, and if the attack is non-scalable to more than a few devices it is usually accepted as secure enough...

1. Remotely attack a car and disable the brakes.
2. While in the car in the car disable the brakes.
3. While in the car required to unscrew a panel to disable the brakes.
4. Before starting the car open the hood and connect a cable to the computer and then when driving disable the brakes..

The only really bad one here is probably nr 1...

Devices like this are usually not connected to any network in that sense.... For this one it would only have to be connected if they wanted the vein images from the machine...
There already exists many types of automated systems in hospitals today, like heart-lung machines or how about pace-makers that people are walking around with outside... If they manage to keep the heart-lung machines working i think they can manage to keep this one running too...

ehmm... "Robotic equipment"... quite broad statement... can be anything from someone tripping over an automated vaccum-cleaner to someone walking into the operating-zone of a factory robot...

And most cars are controlled by computers... so why does not the break's fail or the gas locked to the maximum all the time?

You can design safe systems... If something invalid is detected then go to fail mode and safely stop the procedure. Failure detection can be a combination of both software and physical sensors and could be a secondary system that would operate completely separate from the main one.

And Therac-25 is a really bad example of a poorly designed system.... But there is one interesting thing about it on wikipedia...
"The system noticed that something was wrong and halted the X-ray beam, but merely displayed the word "MALFUNCTION" followed by a number from 1 to 64. The user manual did not explain or even address the error codes, so the operator pressed the P key to override the warning and proceed anyway."
So here it was user-fault again... If something says "MALFUNCTION" and displays an undocumented error-message it might be a good idea to check with the manufacturer what is actually is instead of just proceeding...

Also:
"The software was written in assembly language that might require more attention for testing and good design. However the choice of language by itself is not listed as a primary cause in the report. The machine also used its own operating system."

Why did they write this in assembly??? Make it much harder to do reviews on.... If they did it because they had to little cpu-resources then should have added more resources.

Designing software for safety and/or graceful failures can be tricky, but it's not hard...

Possibility

3'rd party site that wants more visitors creates a booking page for many popular resturants... People fill in their information and then they will get a mail if they managed to get the reservation...

It's not so hard to imagine... And a great way to attract more people to your page...

Then don't watch http://www.imdb.com/title/tt1467304/ or http://www.imdb.com/title/tt1530509/ :)

Well.. People that says these things have never been to a 3-star restaurant...... The thing is that the $50 per meal restaurants cannot afford good (good and good... they are probably not bad anyway .. ) ingredients for those prices.... Good wagyu beef costs about $50 for the restaurant to buy for one portion (150grams or so)... Also there is a big thing on how the animals have been raised so you actually should look at the farm where the meat came from.. (Btw, if you have never tried it then don't... it will ruin all other meat for you :)

Never buy chicken that have been grown in 7-9 weeks and basically force-fed with corn.. Buy a free-ranging chicken that has been grown in the natural speed.. It tastes so much better.

Never buy salmon (or any fish) from fish-farms. To start with they contain less Omega 3 (the good one) and much higher concentration of Omega 6 (one of the bad ones). They are also fed antibiotics and dye to give the flesh an appealing red color... Also fish from fishfarms contain much higher concentrations of PCB/pesticides and other harmful chemicals.

Never buy beef that have only been fed corn, as most meat-animals are. Try and go for free-ranging cattle from a fairly tempered areas with lots of good food...

There is a difference in food and food... And going for quantity over quality is always bad..... Buy a good meal and enjoy the experience... If you are still hungry afterwards then have some fruit or grab a sandwich..

To start with you should read up on this. Radioactivity from coal-plants are actually quite high in comparison.
http://en.wikipedia.org/wiki/Background_radiation

And about the linked article.
To start with i do not believe their statement of 15CPS they stated since they said that this was about double the normal amount, but normal backround radioation is ~20-80CPM so they are off by a factor of altleast 80.
If it would really be 15CPS that would be 900CPM or about 9microseivert per hour and that would be quite huge... But even at those levels
And as they write they found areas with up to 50CPS and that would be 30microseivert per hour and that would be spectacular if nobody except one small paper would have picked up on...
But on the other hand, even with those extremly blown up figures you still only have an increase of cancer risk of 1 in a 1,000 per 12.5 milliSievert (mSv) (or 12500microsieverts) so that would still take about 416 hours to increase the risk by one in 1000 at the most extreme value they reported.

But then the next question is quite important.. What type of radiation is it? Gamma/Beta/Alpha??? Gamma can be quite bad, but Alpha is quite safe unless you manage to inhale highly radioactive material that i doubt exists on that beach with those levels, even if there was 15CPS.....

Just a few simple things that can bring up the background radiation:
- Soot/ash from coal-plants, actually it can be quite high in really bad stuff.
- Spill of potassium (fertilizer)
- Concrete
- Stone from a quarry that contained a bit higher PPM of uranium.

"That is double the amount of radiation normally found in the atmosphere in Britain" this is comparison is also completely invalid.. You don't measure the atmosphere, you measure the ground or material around you.

Normal background radiation is between 25-75 in the US, so 15 CPM is nothing...

Read http://xkcd.com/radiation/ and then take into account that 100 cpm is about equal to 1 microseivert per hour.

From above poster:
A trip from NY to LA would give you 40microsieverts/hr ...
During a normal day you will recieve about 10microsieverts/hr...

Well, nuclear causes less death's than any other energy-source..

http://www.forbes.com/sites/jamesconca/2012/06/10/energys-deathprint-a-price-always-paid/
http://www.geekosystem.com/coal-oil-nuclear-deaths-chart/

Or you could do a google yourself on "number of deaths coal oil nuclear"

The thing with nuclear-power is that everything happens at the same place and affects more people in one go..... And i prefer something that kills ~90 people per year over for example Oil that kills ~36000 per year... Or natural gas that kills ~4000 per year.. Even wind-power kills ~150 per year....

The problem is that it's public opinion that drives the direction of how we generate power, but the problem is that the general population don't have the knowledge to actually make an informed decision, and neither can i fully.
The thing is that nuclear-power, and there are many types of technologies, is probably the only thing that will be able to sustain the human population for the next 50 years until we can perfect fusion-power or something else that do not have the same impact.

If nuclear-power would still be seen positive by the general population we would also build new reactors that are safer instead of staying with the old reactors that have known safety issues.

Makes me sick of a justice system where a 11'yr child could be charged with a crime for something like this.... Does not matter if he was autistic or not, but autistic kids might even flip out a bit more if someone grabs them (not sure if that's the same for everyone?)....

Any police should be able to handle a 11'yr old kid verbally, and worst case taking a hold of his arms and then getting a kick or two from a kid is not really that bad.. If someone work as a police-officer they should at least be able to handle a few bruises when handling kids..

Kids are kids.. They flip out from time to time and it's normal..... The strange thing seems to be that the police that are sent to schools don't get any proper training on how to handle kids..... And working in a place where you have autistic (and other things too?) should require quite a bit more of education...
