mitchellberry··on RTL-entropy: Uses RTL-SDR to turn a DVB-T dongle into an entropy source
Would be interesting to see this run through some statistical batteries. DieHarder and TestU01 still seem to be the gold standards.

XOR it with /dev/urandom, the result will be as strong as the best source of entropy.

>Exchanges don't actually hold the things they're trading.

Bitfinex has a few billion in publicly known cold wallets.

mitchellberry··on HodlFeed – a Cryptocurrency Newsfeed
Your dollars already do get more valuable over time wrt consumer electronics and cars, yet people still purchase them en masse.

Many still spend in a deflationary environment, they just do so with far more care about the product and it's longevity.

People will invest also, though only with a expected return greater than deflation gains.

Instead the status quo is being forced into overvalued equities or real estate investments. There's no real option to be a saver in the western world anymore.

mitchellberry··on A Cryptocurrency Website Changes Its Data, and $100B in Market Value Vanishes
No one measures the marketcap of gold or soybeans. When was the last time someone mentioned the marketcap of the USD?

It's an absurd metric made worse by the fact that more coins are issued every 5 mins. If price remains the same virtually all coins will go up in marketcap regardless.

What company issues new shares every single day?

mitchellberry··on Live CO2 emissions of electricity consumption
I pay 29c/kwh in a country with abundant solar, wind, coal and uranium. Perhaps there is something more at play here?

Public education about grid engineering and its challenges would be a good thing.

Apart from the asteroids packed with precious metals or water/zero-g vacuum manufacturing /virtually limitless solar energy and near earth rendezvous from interstellar objects?

mitchellberry··on Why you can’t cash out part 1: Bitcoin’s “price” is largely fictional
Fair enough though I'd contend such articles are the motivation for the bubble commentary.
mitchellberry··on Why you can’t cash out part 1: Bitcoin’s “price” is largely fictional
What's the difference between that and the same company buying a pennystock?

This is how markets work.

mitchellberry··on Why you can’t cash out part 1: Bitcoin’s “price” is largely fictional
> All it takes is a change in the media narrative.

Every article I read in the media has huge negative sentiment already. Can you point to some positive articles about bitcoin? Seems to be very few going around, it's all bubbles, energy consumption, hackers, ransomware and terror funding.

Wondering how the narrative can change for the worse from here.

mitchellberry··on Why you can’t cash out part 1: Bitcoin’s “price” is largely fictional
> worth pointing out that less than 1000 entities owns 40% of the bitcoins

The fiat equivalent is saying 10 entities own most of the USD in the world. They are banks with liabilities holding money for others.

Of all the bitcoin conspiracies it's provably false yet people somehow gravitate towards it.

Do worry how easily people and especially journalists fall for this. Go click on the top 10 addresses in a chain explorer, please. They are all exchanges.

mitchellberry··on US prosecutors move to cash in on $8.5M in seized Bitcoin
The most funniest part of this oft-repeated argument is that currently bitcoin blocks are full, the mempool of pending transactions is at record highs and people are happily outbidding each other in fees.

Though apparently no one is using it if you listen to the internet.

There's a massive dichotomy between the cryptographically provable transactions and commentary. Someone is obviously using bitcoin. It's at max capacity.

mitchellberry··on Tesla largely responsible for slide in U.S. home solar sales
Solar and even moreso batteries are advancing so quickly that waiting for further price deflation seems a logical choice for many.

It's the energy equivalent of holding out for next gen cpu's.

mitchellberry··on A Cryptocurrency Without a Blockchain Has Been Built to Outperform Bitcoin
Rolling their own crypto should be a huge red flag by itself. Watching others defend that decision screams vested interest to me.
mitchellberry··on Recycling Chaos in U.S. As China Bans 'Foreign Waste'
So if China were to split into 10 different countries it would somehow become an acceptable level?

Per capita is the only equitable measure of pollution.

I certainly agree overpopulation of the earth is a tragedy likely felt for generations, but petty bickering over these very issues is why global leaders can't make any progress in greenhouse gas emissions.

mitchellberry··on Police Homicides in the United States
Yeah fair call, just don't like the blame game that seems to escalate in cases like this.

Police should certainly worry about general opinion. They are public servants.

mitchellberry··on Police Homicides in the United States
Seen people demanding the names of jurors on various forums.

This is the antithesis of modern justice. Despite my personal feelings about their decision, jurors should never have to fear public opinion.

mitchellberry··on Did Bitcoin just prove it can't scale?
If i gave you a search algorithm with a big db then asked if it could done quicker would you prefer to spin up more cpu's or try to improve the algorithm?
mitchellberry··on Bitcoin boom may be a disaster for the environment
AMD already building coin mining optimised gpu's, making the algorithm memory-hard to exempt asic's doesn't really change much except the direction of hardware manufacture
mitchellberry··on Bitcoin boom may be a disaster for the environment
I can write anything i want into the bitcoin chain for $1 and all the computing power in the world wouldnt be able to undo it after a few days.

Even quantum computing can't touch it (though can trivially work out my private keys).

Many people throughout history can and have been censored, don't see that changing soon.

The bitcoin blockchain is a modern technological wonder without anyone really appreciating the power at their disposal.

Using it only for transactions now is like hiring a tank so you can go get money out from an atm. Predict eventually use cases will come into their own.

mitchellberry··on Don't Talk to the Police (2012)
People don't realise how natural a reaction this is also, if your pants are coming off it's muscle memory to grab them.
mitchellberry··on The U.S. Leads in A.I, but for How Long?
This article seems more higher education or tax policy discussion rather than about AI/ML.

Still intrigued though, is "world rankings" possible to determine or even valid in a multinational corp world?

What was the last actual eureka moment in ML?

Apart from some hello worlds know little on the subject, from the outside looks like the heavy work was done long ago and we've only recently had the hardware advances to make it a reality. Seems to be incremental improvements on models and a myriad of new ways to implement neural nets, but the real improvements are coming from nvidia/amd engineers making gpu advances.

Hardware has moved on but we still in the same position of engineering tradeoffs and physical limitations. Undoubtedly there's wizards out there who can work wonders, and there's people less adept with nation-state resources who could can achieve the same result.

I'm partial to the opinion that being a world leader in ML right now has more to do with your hardware and budget rather than individual talent.

mitchellberry··on Police Homicides in the United States
You watched the entire video?

It's 5 minutes of conflicting instructions and repeated death threats by a man heavily covered in tattoos carrying an assualt rifle with the words "you're f*ed" engraved on it.

How were the multiple police officers incapable of handcuffing the clearly compliant crying victim in 5 whole mins? Am amazed anyone watching that could possibly defend it.

mitchellberry··on Goldman Sachs Plans to Clear Bitcoin Futures When They Go Live
"Fees"

I see the margin lending rates on some exchanges right now being 0.003% daily. This is for coins that move 10% a day.

Probably fair to assume fees aren't what the traders lose sleep over.

mitchellberry··on US Military's Microwave Weapon Can Fry North Korean Missile Electronics
Certainly there are fair reasons for hiding capabilities, and they seem quite adept at determining what is going into the sea or not, but in a war of words environment if it was a certainty as THAAD propenents seem to claim a single shootdown would be a huge PR blow for nk.

It's just not reliable enough to risk and as such is still a last resort measure.

Defending against a nuclear ICBM is not possible to do reliably. It's a sad reality.

mitchellberry··on US Military's Microwave Weapon Can Fry North Korean Missile Electronics
Am just an armchair commentator but surely NK already has hardened facilities prepared for an EMP from a nuclear strike?

I don't see how a b52 with a kerosene powered engine is anywhere near capable of delivering that same level of radiation.

mitchellberry··on US Military's Microwave Weapon Can Fry North Korean Missile Electronics
There is not any proven tech that can take down an icbm reliably.

This is reassuring propaganda plain and simple.

If the US and allies could take down a rocket they'd shoot down every NK test missle just to make a point.

Absolutely delusional saying this system can take down consumer drones and then extrapolate that out to a missle that is travelling at speeds measured in machs.

Even with drones I don't see how this is more effective than radio signal and gps hijacking which can control a malicious drone rather than destroy it in place. Various companies already do this incredibly well, shoutout to D13.
