Comment fundamentally different (Score 1) 72

They are fundamentally different.

On one side you have turn-by-turn games, that progress in fixed steps, and thus simply paint the game field by putting varied wall graphics at exact predefined places.
It's really the discrete position on the map and cardinal headings that are specific,
(That's what you get in most classical RPG).
Could very easily be done back then with a few lines of code. The biggest chunk of work came from the *art* to have a big enough choice of wall to draw to make an interesting world (because it's mostly static, you'll be spending a lot of time at the same, and need something nice to look at).

Basically, the graphic engine has a fixed grid on screen and you put different sprites at said fixed grid positions.

On the other side you have game engines that try to have some actual notion of 3D built into them and allow smooth motion, with complete arbitrary position/headings.
(That's what you get in most FPS and real-time RPG like ultima).
There is really require more advanced coding. (With Origin more concentrating on making an imersive game, emphasis on beautiful graphics, and ID concentrating on make their engine fast and responsive, sacrificing any detail necessary for the sake of being able to make a fast paced game).

Basically, the graphic engine use geometric techniques like wolf's raycasting do determine what is visible where, and gives you total freedom (or at least tons more of freedom, as Carmack used limitation to beat Ultima in speed and fluidity).

From a basic visual composition, both categories have a first person perspective.
From a technical point of view, they are designed completely differently.

Comment Point of comparison (Score 1) 981

Eventually, even the dumbest of the dumb will realize that it doesn't pay.

The dumbest of the dumb can only realise things are going badly when they can compare with things going well. To realise that the current government fucks everything up require to be able to realise that some things could be a little bit less fucked up, and the reason they are still so bad is the government's fault.

But if a country is shot down into dark ages, that gets much more difficult. See the reports about fugitive who have escaped extremely isolated dictature like North Korea. These people had probably the vague notion that perhaps here in the west, things are going a bit easier that in their country. (That's why they ran away in the first place)
But having so few information means that these people are just completely amazed by how far off their perception of the outside world has been, they knew that things could go in a different, better way. But they weren't able to realise that outside the totalitarian prison things are SO different.

Comment Worst summary ever (Score 2) 106

Indeed, IB Times wins the record of the worst ever summary of microbiology subject.
(mixing virus and bacteria and toxins. And multiplication and dead cells. W.. T.. F.. )

(Also, the magnets have nothing to do with the removal. They are just the mecinal technique used to move the metal beads around. It's the manose-binding lecitin on them that hold the magic.
It's not "removing Viruses and bacteria using magnets" but "removing them using lecitins which happen to be moved around thanks to magnets").

The nature paper it self is good, and the method is typical technique used for extraction / purification (so the principle is solid).

The relative novelty of this method is that, instead of using an antibody as the binding agent (something that needs to be targeted specifically. In vertebrate they are part of the *adaptive* immunity : immunity that the body needs to train) this method uses manose binding lectins (something that isn't specific and bind to lots of targets: bacteria, virus, toxins, etc. In eukaryote, they are part of the *innate* immunity: immunity you are born with, you don't need to train. Your body will already produce lecitins against sugar patterns that aren't frequent in your body, even if you've never encountered them).

Thus, its able to purify and extract from a patient's blood bacteria, virus and toxin *THAT YOU DO NOT KNOW beforehand* (i.e.: anything that presents a pattern of sugar on the surface that isn't common in the body and for which they have the corresponding lecitin).
(Where classical extraction usually rely on antibodies targeting what you would like).

It's a bit equivalent to use coal to purify blood: coal will indiscriminately extract any big organic molecule without you needing to know it in advance and thus is a valuable tool in case of poisoning

Comment Smaller vehicle (Score 1) 139

car emissions come out

Now, regarding the CO2 emissions, this might be solved by using a lighter vehicle for such errends.

To transport a few clients and their suit-cases to the airport, yes, a Uber driver needs a big-enough car.
BUT!
To carry and drop around a few lunchboxes or pharmacy bags, a Smart car, a motorcycle scooter or an e-bike is pretty well enough.
(Also european cities tend to have separate lanes for bikes, meaning that the Uber driver can bring your delivery while avoiding traffic jams).

Now on the other side, there are health benefits in taking a break and walking a bit to pick up your food.

Comment Pharmacies (Score 1) 139

In Europe and Asia there are already services like this.

Random example of such service in Geneva, Switzerland.

Pharmacies also operate their own such services (it's a popular job for high-schoolers to earn a few bucks).

Plus there is generally a delivery charge (or the restaurant gives up a cut). If each delivery is $5, zipping around from house to house would be a very good job if it's organized correctly.

And, unlike taxi service, can also be achieved with much lighter transportation vehicle (said drug-delivering high-schooler tend to do it with their motocycle scooter, e-bike, etc. also because it's easier to get a license for it) which overall can potentially lower emission and lower traffic in dense cities.
(well at least here in Europe where bikes, e-bikes, light motorcycle, etc. are very popular... in gaz-gurgling-SUV-land, well, YMMV).

Try Kickstarting A Novel

You mean like this ?
This proves it possible although (as in the case of Star Citizen, and the likes) it got successfully funded because the book has big names behind it: Zach Wiener and Boulet.

I'm always amused when wanna-be novelists want people to give them $50,000 to write a novel in a year and discover that no one will give them money. The novel must be written first.

The book COULD be not finished yet:
- ...if it comes from a known guy. Popular author which has already shown able to produce good work. Can have successful kick-starter (I have this great idea that I want to write about, but my current publisher considers it a bit riské and doesn't want to shell out all the money for it).
Basically, any idea proposed by Terry Pratchet would get insta-funded, no matter how weird the premises.
- ...if it again follows the "prototype" rule. Wannabe authors writes "Chapter 1" on his free time and decides that he want to get paid to make the rest instead of having a main job and doing the book on the side. Wannabe authors makes chapter 1 available. Interested reader notice that current work is better quality than the crappy fan-fic which pollute the interweb and that the wannabe authors shows promising qualities. Book might get funded.
- slight variation of the above: a blogger who has shown very good and promising writing ability. Nothing from the book exist yet, the authors hasn't written a book before either, but has repeatedly shown to be able to output massive amount of written material with a good sense of humour.

Notice that, both situation could also work with a publisher. The only reason to go for Kickstarter is if for some reason no publisher is interested in the material it self (the project is REALLY weird, or the main theme is controversial, etc.)

The main difficulties won't be finding potential funds for Kickstart (as in fact, the main difficulty won't be finding a publisher neither, if the project isn't too much weird).
The main difficulty would be the lack of experience in handling a publishing project.

Comment from *ANY* bitcoin exchange (Score 1) 34

You still need to get the money to and from the Bitcoin exchange.

...to and from a bitcoin exchange. any bitcoin exchange.

Unlike Western Union that you mention (where you're basically stuck with only one single service provider per system), bitcoin leaves you with full freedom of choice of how to process the BTCs you received (coin processor, classical exchange, face-2-face meeting like localbitcoin, or simply keeping them in BTC form to re-use them (just watchout for currently big market fluctuations)).
And your choice of method at your end has no influence at what I chose at my end.
I, the client, could be using localbitcoin, and you the merchant could be using coinbase.

So Paypal, Western Union, or TFA's WebPay aren't directly comparable to bitcoin transactions.

SEPA are more similar: any SEPA-enabled bank in Europe can send amounts of money to any other SEPA bank.
I might be using a Swiss bank, your bank might be German. But both of us can pick any account in any bank as endpoint, as long as both banks support SEPA.
(And bitcoin are a bit faster than SEPA payment).

That's some improvement compared to the current situation of payments over internet, where you're basically forced to have a PayPal account, and have a MasterCard/Visa credit card, just because that's what most of the web is using.

Microphone will pick up *a* bang, and thus will give an information when *some* gun was fired in the vicinity of the police.
It could be any gun on the scene, might by the police worker's own gun just as it could be the gun of the suspect/criminal.
(Though if there are multiple police worker, with multiple microphone, maybe one could triangulate a probable point of origin for the shot)

This wrist bands pick up vibration, and thus will give an information when *the gun held in the hand wearing the wrist band* has recoiled (and thus fired).
It's the exact gun in the hand of the police worker, very few doubt about it.

Comment Following the trail. (Score 1) 134

Regarding: 1, 2 and 3 :
I wasn't referring to matching single transaction/single keys and IP adresses, etc.

I was more referring that, if you want to use bitcoin in a meaningful way, you'll have to interract with the real world.
At some point, a real bitcoin user who isn't just playing with bitcoin for the sake of it, will buy an actual good.
Meaning that the seller will need to send the goods to an actual address.
At the other end of the chain, a would-be future bitcoin customer will need actual BTCs to do transaction. Nowaday it's not practical to mine any significant amount of BTCs using hardware available to the average customer. That means that a future bitcoin customer will need to acquire BTC, usually buying them from money (from an exchange or following a face-to-face meeting, etc.)

So no matter through how many public key the BTCs hops, a motivated enough investigator can always track indentities at both end of the chain:
- initial acquisition
- final spending.
sometime it's going to be the same identity (because it's the same person buying the BTCs and spending them after a few public key hops in-between), sometime it's a different identity (because somewhere along the chain, the BTCs 'changed hands' in a way that wasn't registered and matched to any address: for example 2 random people seeding direct donation to each-others address without an real-world interaction. Might happen several time along a chain).

If a really motivated investigator has enough resources (now we're speaking government-level), it is possible to follow tons of such "money trails". By comparing all of them together, it is possible to build whole nets of interactions, and you can match real identities. Even when 1 single money trails is uncertain (money might have switched hands along the track between known end-point), taking into accounts lots of other such money trails help lift uncertainty.

#4) You can use tumblers and coin exchanges to disconnect a given key from you and a transaction.

That's a good valid way to blur the trail.
In the block chains, what you'll see is thousand of user pouring money into the exchange (user funding their accounts) and thousand of users getting money back (user doing withdrawal from the exchange account). Everything in between happens "behind closed doors". The actual buy/sell actions aren't recorded in the blockchain, they happen in the exchange software's database. In the block chain there's just the exchange who's officially held amount of BTCs corresponds to the amount of BTCs currently being exchange by all users. More or less (see MtGox's heist when those numbers don't match anymore).

So trying to make sense of the complex network of interaction is *hard*, *really hard*. Well beyond the efforts used in simply "lifting uncertainty due to invisible switch of owners". Probably only a few poeple in Russia's FSB and US' NSA might have a slim chance of tracking a suspect. (And the tracking is more likely to rely on backdoors and trojans).

Comment Freeze (Score 2) 134

Joking aside:

at least bitcoin has on purpose been designed in such a way to make it impossible for a central authority to freeze an account, because on purpose there are no central authorities.
So that's a relatively small advantage over paypal.
(although, in both case, these system should be used EXCLUSIVELY for payments only. You should only use them to push money around, you should NOT use them to store money. Neither Paypal, nor the bitcoin network are banks. So if you got a big amount of money frozen, it's only your own fault).
