It's mostly unstable up. Virtually anyone who holds Bitcoin over 1 year sees their savings not lose value, often with a good upshot, unlike _every_ currency in the world.

Phrasing it "extreme of either side" sends a message that you place either extreme in the same moral bucket. Some people may argue that extreme personal protection is good and extreme personal vulnerability is bad, which makes the

Have you looked into VRFs (verifiable random functions)? This is essentially a public key crypto version of HMACs. You have a piece of data and a blinding factor, both are committed into a single point on an elliptic curve, and blinding fac

I think it's only fair to compare dockless scooters/bikes with dockless cars. https://slate.com/business/2018/04/astounding-photos-capture...

Monero is less scalable because you have to store all tx outputs (key images) instead of just unspent tx outputs, since Monero does not know which outputs are fully spent (for larger ring sizes). And these must all be stored in fast random

I don’t see how your insult adds any value to the conversation. I can equally argue about you narrow-mindedness while bluntly stating the opposite argument.

10 days of mining alone = 1440 blocks = 72K BTC at 50 BTC/block. $1M per coin gives $72B, not $1000B.

Bitcoin never escaped the "trough of disillusionment" since its birth. 2008: Satoshi posts a paper to mailing list, nearly everyone declares the idea non-workable. 2009-2010: Satoshi releases software, no one cares. People throw a

What you described is called "second preimage attack", that's != "first preimage attack".

Yes. From $10-15K to $5-7K. Just like it collapsed from $1000 to $300 in 2014, or from $270 to $100 in 2013, or from $15 to $10 in 2012, or from $30 to $3 in 2011.

So did computers and tcp/ip. Should we roll them back too?

APS-C fujis with their excellent XF lenses are simply 2x lighter than DSLRs and still lighter than full-frame Sony a7.

GC highlight time-memory tradeoff at its worst because GC-based languages typically do not allow programmer to explicitly express his memory model forcing a lot of unnecessary "garbage" to be created. In Ruby all objects that do n

This is similar to "stack promotion" in Swift ( http://fossies.org/linux/swift-swift/lib/LLVMPasses/LLVMStac... ). Objects that can be determined to stay within a local scope get allocated on the

Here is my proposal for syntax support for the existing callback+libdispatch patterns: https://gist.github.com/oleganza/7342ed829bddd86f740a#async-... The idea is to flatten the syntax without change of the runtime mod

Encrypting to a ECC public key will involve Diffie-Hellman process described above, plus extra data mixed in. So just D-H would be easier ;)

Why implicit? There are braces around `now - INIT now`. In Ruby it'd be "Code took #{Time.now - start_time} seconds to run".

I can't help but notice that the only news about Bitcoin that ever enter HN front page are some sort of drama, or "issue with bitcoin". There are a lot of truly great things going on in the space, yet these are carefully kept

In case of Bitcoin pubkeys you don't want to publish them anywhere for privacy reasons (that turn into real physical security reasons once you have enough BTC). Also, notice how pubkeys are normally hidden under hashes and revealed onl

Not exactly. You can prune txs if you don't need to keep them for archiving purposes. But you have to validate the whole blocks to verify your own payments. You cannot selectively validate portions of blocks ("shard blockchain&quo

Yup. And my comment is about when it does and when it does not matter that you make more and more of them. If your society is in fiat credit bubble, then you are doomed into Mad Max Scenario when you slow down the exponential growth (bubble

Exponential growth is needed only for keynesian economists because it keeps their pyramid scheme called welfare state running. If you have a decent one-digit economy growth on non-inflatable money (bitcoin), then everything Just Works. Mone
