spiorf··on Bitcoin emissions alone could push global warming above 2°C: study from 2018
Actually, the "inefficiency" of everything is converted to heat. So, a PC is more efficient because it does useful work in the meantime.
spiorf··on Bitcoin emissions alone could push global warming above 2°C: study from 2018
This is completely wrong. They scaled energy with number of transactions.

> At each time step, CO2e emissions for the given number of transactions were estimated based on the emissions generated to mine that number of transactions in 2017.

Bitcoin network does not work that way. Energy is spent securing the blockchain, not per transaction.

Why does every article about this talks about the energy per transaction? Energy spent is completely independent from the number of transactions.
spiorf··on An Absurdly Basic Bug Let Anyone Grab All of Parler's Data
Being a public website is not a "bug".

Being able to see deleted posts and download deleted videos is a bug.

I consider a bug also not stripping metadata from videos and images on upload.

spiorf··on Ask HN: Is there any alternative to Dropbox?
I tried that, but i missed the remote storage. I use Nextcloud and is almost a perfect replacement for dropbox.
spiorf··on There's No Good Reason to Trust Blockchain Technology (2019)
You will not be on the main chain if the modified version changes some consensus rule. That's called hard-fork. Look at the segwit2x debate to see how this worked in real world.

If a modified version doesn't follow the same rules, it will never finish the initial sync.

And you can still sync with very old clients. Most of the work on the bitcoin client is optimizing validation. Consensus rules are rarely touched.

Transactions are already public.
spiorf··on Pentagon official: FCC decision on 5G threatens GPS, national security
Deploying a 10KW sat is not a problem. Replacing a whole fleet just to keep it operating the same way as before is.

That train departed a few weeks ago.
spiorf··on “Just walk out” technology by Amazon
I bought a new phone in a store, then bought a cover and a screen protecton on amazon. It sent me a notification: "We think you might be interested in a new phone".

It's pretty obvious that people don't go around shopping for screen protectors and then buy phones to match.

spiorf··on Europe sees warmest winter since records began
> rom what I read long time ago (before the global warming histeria) this is cyclic - periods of warmer climate intertwined with ice ages.

For a bit of perspective, see https://xkcd.com/1732/

spiorf··on U-Haul to Implement Nicotine-Free Hiring Policy
The survival of hundreds of people has more value than freedom of an individual in his free time. One should not be allowed to put other people at risk for fun/entertainment/whatever.

Profit for a business, on the other hand, must not have more value than freedom of an individual. Otherwise, taking this to the extreme, it means slavery. Max profit for no freedom.

In a way NSA did publicly disclosed Eternalblue.
spiorf··on A Teenager's IoT worm is bricking thousands of devices
If your air conditioner clicks on after 3 seconds, you push the button 3 seconds earlier.
spiorf··on Amazon can't yet completely delete Alexa voice transcriptions
The issue here is that a not too powerful local device could do that without recording everything you say in the cloud and keeping it forever with a label with your name on it.
spiorf··on Amazon can't yet completely delete Alexa voice transcriptions
Because it does upload everything you say to the cloud, and saves it for undisclosed amount of time, and has the ability to link those recordings to your account and the motivation to exploit it for business purposes? Not to mention possible data breaches in case that data is not perfectly secured.

spiorf··on Ten Years of Bitcoin
Maybe the information asymmetry is part of the problem itself. Banking system is centuries upon centuries of arbitraty constructs. It does not make sense from the ground up.

I cleaned browser cache to fix it. didn't work.
spiorf··on Ask HN: What's your favorite elegant/beautiful algorithm?
Bloom filters are interesting. A bunch of different hashes as kind of fingerprint that make search fast but with caveats: negative answer is negative, positive answer might be negative.

Haha, "your" library...
spiorf··on Bitcoin’s Price Was Artificially Inflated Last Year, Researchers Say
It would be an economic suicide for the first country that decides to disconnect itself from the internet. Or do you think that for the first time in history of mankind, every single government will come together against bitcoin? Besides, there are satellites beaming down bitcoin transactions, so...
spiorf··on Bitcoin’s Price Was Artificially Inflated Last Year, Researchers Say
51% lets you censor transactions. You need more than that to reverse a week old tx. Way more. You have to outrun the rest of the world and gain a week of advantage. So if you have 90% of the hashrate, you go 9 times faster than the honest miners. Every day, you can erase 9 days of blockchain. But that 90% means that you build a mining farm that is 9 times greater that the current hashrate. Redo the math on the costs and logistics of that.

This is the internet, and those weapons can't fire down here. Try, instead, to delete a two week old transaction from the bitcoin blockchain. You will find that even with military-sized funding, you can't. That's what is backing up bitcoin's value

spiorf··on Bitcoin forks and airdrops
By market cap. That is a meaningless number for a coin that magically rained on those who have bitcoins.
spiorf··on Bitcoin Futures Start with a Bang as Rally Trips Circuit Breaker
If you do that, in a year a new full node will take a year to fully sync. That means no new nodes. That means that over time bitcoin is dead.

That's just luck. The 10 minute is an average. There are times where you need three hours for 6 confirmations.
