Comment Re:Bitcoin, Ethereum or Monero (Score 1) 96

On the fringe you can add Monero

Fringe? IMHO, Monero is the Microsoft of second generation cryptocurrencies -- it's the big, slow, conservative choice of Cryptonote coins. For a leaner and generally more interesting alternative, have a look at Boolberry, but keep Monero in mind for long-term investment. (At the moment, a Monero node is taking over 14 GB of virtual memory on my machine, Boolberry "only" 4.)

It looks like the OP is a newbie to cryptocoins, so let me elaborate a bit. Traditional 'altcoins' are based on the Bitcoin codebase, so for things like proper anonymity, look for independently developed codebases such as Cryptonote (whose implementations include Monero and Boolberry) and Ethereum.

For mining profitability, Boolberry and Ethereum on GPUs are doing nicely at the moment, Bitcoin and Monero not so much. Of course, this may change rapidly and you need to do your homework. Good old bitcointalk.org is still a useful hangaround for learning about coins, though many notable coins have their own forums for more detail.

Bitcoin is still the gold standard in value of cryptocoins, technically viable and well accepted by merchants. Forget about mining it, but don't dismiss it otherwise. For example, the programming aspects of Ethereum were largely present in Bitcoin already, it's just that Ethereum takes these to the front stage and makes them easier to use.

In the physical world, there are plenty of things that involve frequencies in the analog sense, and there you find bandwidth in its original meaning. These things include digital transmissions when you consider their physical representation, so it's important to people that design "broadband" modems, for example. They also include completely analog systems such as human hearing. I understand that laypeople often take scientific terms and use them in some vague, narrow and "wrong" sense, but that's far from having the actual scientific language evolve.

If the network speed were crazy high enough, you could run as if you had completely dynamic RAM online for loads that suddenly require it (that would require an approximately 100Gbps connection, FWIW).

Latency would still be an issue, so this wouldn't replace local RAM for all purposes, though it could be good enough for some cases. It's more like a disk than memory, and many people already use The Cloud(TM) this way, privacy and availability be damned.

I technically know how to type both on German and US keyboards. In practice, I find German layouts to be incredibly tedious -- even when typing German.

I much rather prefer a US keyboard layout and a working "Compose" key. Typing accented character is very straight forward and logical when composing the character from its underlying parts. Yes, it requires multiple keystrokes to type a single character; but I have gotten pretty fast at typing those.

Alternatively, some of my friends/relatives have switched to a US layout and refuse to enter native accented characters altogether. German officially sanctions the use of substitutes "ä" becomes "ae", "Ö" becomes "Oe" and "ß" becomes "ss". Maybe, the French should come up with a similar system.

It's the same issue in Finland, coding on our native layout is excruciating. Fortunately, there are simple ways to change the layout on the fly, for typing longer native texts, such as

setxkbmap "us,fi" -variant "altgr-intl," -option "grp:alt_shift_toggle"

The US intl variant is nice for having combos like AltGr+q for ä rather than separate accent/compose keys.

'S' (for "Statistics" - originally with single quotes, those are usually being dropped now) is a programming language created in 1975-1976 at Bell Labs (which had a tradition of single letter named programming languages, such as C) on General Electrics GCOS mainframes and since 1979 on UNIX.

I guess back then they didn't worry about the name being easy to google, unlike today's new languages with unique and descriptive names such as "go".

regular spinning drives don't provide any assurance against catastrophic data loss, either. you should always have backups.

When the power suddenly goes out, regular spinning drives don't generally lose everything that's already on platters. With SSDs, their internal state is more in flux, as older blocks can still be reorganized all the time. Also, there's much more logic between the actual storage and the outside interface, so a bad controller can easily make everything inaccessible, even if the data is still there in the storage medium.

I agree that alcohol is an addictive drug. What bugs me is its classification relative to other drugs in most Western jurisdictions. To get the psychoactive effects of alcohol, you need to drink huge amounts that mess up your body in many unwanted ways. Apparently, our governments prefer this to specific psychoactives that work in much smaller amounts.

Comment Re:You shouldn't use one hash. (Score 1) 87

hashsha1(hashmd5(data)) is strong

A hash is a many-to-one function. If you combine many hashes this way, you'll map a huge range of different data onto the same output. To me this seems it would be easier to find collisions, not harder. For starters, the output of sha1 has a fixed length, which greatly limits the range of the final output.

Combining different hashes is a good idea, but one weak link in the chain will probably ruin it all. I'd rather combine the outputs of different hashes into one long string to keep them independent.
