Zec because transactions are NOT public, which is proving to be a problem with BTC
ZEC hides transaction amounts, so the coin supply is not auditable: if someone finds an exploit to create extra coins for free, there's no obvious way to expose the flaw. It may have happened already. Besides, the underlying Zerocash tech is only understood by a handful of cryptographers.
Conversely, Zcoin uses the older Zerocoin protocol which only hides addresses, and it is much more widely understood. Then there's also the Cryptonote family (Monero, Aeon, Boolberry,..) with a lot more mileage in the privacy coin scene.
Prominent Finnish Bitcoin entrepreneurs have indeed compared the current situation to the Dotcom bubble of 2000. There was a lot of fluff, but a lot of solid tech too -- you're using a lot of Internet products/services as we speak.
lol no. Sheesh. Acronyms are pronounced as words. Initialisms are not.
"UFO" is both an initialism and an acronym. It is an initialism because, you know, it is formed from the initials of its constituent words. Just like your wrongfully lower-cased "LOL".
The real question you should ask yourself: Why can Japan have vending machines everywhere like this, and not have them destroyed almost immediately by thuggish little shits.
Or, why does one "culture" include lots of thuggish little shits.
Personally, I was more surprised by the extreme variety of vending machines in Japan when reported by a friend, never having been there myself. In Finland, we have almost perfected the nanny state so something like tobacco vending machines would be unimaginable. And I'm not sure what to think about the machines for buying used panties.
Salt water is more than just a better conductor than fresh water. Pure water doesn't conduct electricity at all; it's an insulator,
Pure water is slightly ionic due to its amphoteric properties, though in practice there's not much conductivity to measure. https://en.wikipedia.org/wiki/...
I agree that network transfers are better for the environment than hunks of plastic, esp. with the associated costs of transport. However, streaming is needlessly wasteful when you could have local copies. Streaming is a choice dictated by businesses who want to control every single listening experience -- we already had our environmentally friendly (pirate)? copies before that.
Oldskool radio is great in that you don't need to waste transfer capacity for every single copy received. Live streaming with broadcast packets would be great, but AFAIK it's not feasible.
You're right, we have options -- Linux is not systemd. I use a Linux distro that doesn't use systemd by default. Plus it's the same distro I've used since 2003, not one of these forks like Devuan that were created to escape the parent distro's systemd mess.
"Crypto" is simply a prefix meaning "hidden", so there's no reason why it should stand for cryptography any more than cryptozoology. OTOH, there are well-established cases where the prefix takes over in this sense. For example, "automobile" became just "auto" in many languages. So instead of driving "mobile", the thing that moves, people drive "self", which is probably fitting in this "culture".
In this particular case, "cryptocurrency" is actually shorthand for currency based on cryptography; it's not necessarily "hidden money", but the ownership and transfer thereof is guaranteed by cryptography. In a way, the meaning of "crypto" as cryptography is assumed, but then you have another level of such shortening into the prefix.
Still, it doesn't make it any more correct. I guess cryptographic currencies are "crypto" as in shady or criminal, but there's nothing shady about using HTTPS for regular banking.
This. I'm generally annoyed by all Slashdot discussions where the subject touches my particular expertise, such as physics. Not the news themselves, but the same old supposedly funny/insightful comments. I'm much happier reading and commenting on something like graphics cards, where I can be the super enthusiastic idiot.
He's a billionaire in America because the current value of those Bitcoins exceeds one billion dollars.
I agree with that. However, in the greater world, simply saying "billionaire" is not enough, so it's better to specify the currency. For instance, a dollar billionaire might not be a euro billionaire. Using the same logic, a bitcoin billionaire would mean having a billion bitcoins. Of course, this assumes that you treat Bitcoin as a currency.
Stocks etc. are different because you might have different types of share for each company. There's no single unit of Nokia share, for example, so it's easier to agree that a "Nokia millionaire" has a million local currency units worth of the company.
Also, why say "1 percent of the entire currency's dollar value equivalent"? They have 1 percent of total coin supply, and that won't change whether you compare 1 BTC to Euro or whatever.
With a hard cap of 21 million bitcoins in total, nobody will ever be a Bitcoin billionaire. I'm not even sure if there are Bitcoin millionaires, though Satoshi could well be one.
I haven't done the precise math, but I think my cup of coffee is closer to 2 than 20 cents. I guess you can waste money at home too, if you use something like those proprietary capsule fads.
Nevertheless, I second the underlying idea. More generally, I don't understand why people feel the need to spend everything they earn, in particular, increasing their spending the moment they get a better job. Though I guess it's a matter of personality. I like to keep things simple, and I also like the opportunity of going back to school or personal art projects now and then. Honestly, since starting my first proper full-time job, I simply haven't been able to spend everything I earn, with all the time taken by the job itself.
It's digital fucking tulips - something that has little or no actual value, but an over-inflating price just because people think they can buy it at any price and sell it on for more...
If I had a bitcoin for every time I have to point out "How does one send tulips pseudonymously across the globe to anyone in 10 minutes? Bitcoin is a practical tool, not just a fancy collectible."... oh, wait, I do.
Agreed, but I'd like to take a step back. IMHO, it is idiotic to first write a loop and then vectorize it -- we should have vector types to begin with. We've had them in Fortran for over 20 years, though not necessarily in all compilers as you point out (I remember using a nice SIMD-aware commercial compiler back in 2001). Today, you can use Julia as a modern replacement of Fortran with a free compiler, though you may need to give the @simd hint in some cases.
I guess my physics background shows here. When we manipulate vectors in physics, we generally don't think of looping over all components sequentially; the components are a matter of representation, while the physical vector concept is independent of the coordinate system. Vectors also come with certain assumptions of independent operations per component.
Your post is also a good reminder to the folks who laud C's ability to work at the low level; in my impression, C was designed to act like a very simple processor, so as real CPUs become more complex, the low-level idea gets ugly with backward constructs like loop vectorization. To effectively deal with SIMD etc. you need a higher-level perspective of vectors/matrices, as paradoxical as that may seem.
Similar issues apply to multiprocessor systems, which have also been used in the scientific/HPC field for decades. So it's funny how it suddenly becomes completely new and hard to program for, when the same tech is sold to the general public in the form of multi"core" systems.
A baseball can get 200 feet or more in the air. The lights don't track the ball
Hmm... why not? Hockey pucks were tracked via IR emitters in the mid-90s. I guess a straightforward version would make the ball glow with visible light, so they wouldn't need any upwards lighting at all.
Interesting! There's a football field near where I live, and I've always wondered why they need such lighting as to glare straight into my eyes when I'm a mile away across the lake.
Still, there must be a lot of energy/money wasted, compared to indoor alternatives. Also during the winter, the same field is used for ice hockey etc. so it has a cooling system to maintain ice when it's near or above zero, which happens quite commonly here in central Finland. I imagine it uses quite a lot of power when it's a few degrees above zero and raining, so that would be another win for an indoor ice rink. OTOH, watching the jocks suffer in bad weather is kind of rewarding.

This. I'm a teacher in Finland and this is pretty common knowledge among the staff.

Sending money pseudonymously, independent of banks/corporations, across the globe in 10 minutes is much, much harder if you use tulips.

Came to say this -- Bitcoin is a lot like traditional investments in many ways, including this.

I agree, a lot of my experiences with alcohol also end with an "Oh".
Vodka always makes me want to hack things.
So...the ideal drink for lumberjacks?
Well, it also makes you feel sexy, so yeah. "I cut down trees, I wear high heels..."
