_coldfire··on Bitcoin's ASICBOOST Problem Explained [pdf]
Best summary here, came to this thread all excited for some technical talk, a bit disappointing to see it immediately descend into the madness of the reddit-schism and bitcointalk

Feels pointless trying to argue an opinion lately, all the arguments have been made ad nauseum, nothing new is being said, all that exists is a WW1 trench warfare stalemate.

If proven, having Asicboost hardware seriously undermines Wu et al, but fear the fact will change little. People have taken sides, it's very hard to undo such a thing.

Note there currently is no proof of these claims, it's legitimacy from authority, would be wonderful to see some proof, and who exactly did the testing on the chip? In such a highly politicised environment, evidence is far preferable to sledging your opponent for a week and then backtracking once the damage is done.

Regardless, Asicboost would explain recent actions by mining pools that looks like self-harm to outsiders.

### On a lighter note ###

_coldfire··on How to Get Rich Trading Bitcoin
Ethereum is still doing pointless hash crunching, just with Keccak-256 instead. The energy wastage will go away with a move to PoS

Regardless, the smart contract computing is still removed from the consensus mechanism.

_coldfire··on Bitcoin arbitrage without market risk
A big red flag in the SEC decision was that large arbitrage opportunities exist in bitcoin markets for far longer than is considered normal.

Anyone wanting more mainstream adoption of bitcoin would do well to promote arbitrage trading to as many as possible.

I truly doubt this for a multitude of reasons, but pay alone suggests otherwise.

_coldfire··on France’s military is training eagles to attack drones
>solve virtually all non-military drone events

That's the same scenario I'm talking about. Overpowering the input signals is a proven, scalable defense that can be easily deployed to police forces, stadiums, national monuments across the world and for minimal cost. You simply will not be able to do that with a highly trained eagle.

_coldfire··on France’s military is training eagles to attack drones
You don't need any tech to solve this problem. Simply buy two drones.

I'd estimate one falcon costing easily $100K annually, compared to a $300 consumer drone.

The entire concept is incredibly expensive, doesn't scale and comes with no guarantees, but is certainly loved by the media.

Radio signal hijacking and GPS jamming would solve virtually all non-military drone events. But companies pursuing this rarely get a single mention in the news for the actual advances being made in counter drone technology.

>Bitcoin community is split

Yet not even the advent of quantum computing with todays algorithms could undo a few hours of the Bitcoin blockchain.

A bit too much credence is given to people arguing on the internet rather than the raw state of things. The sheer computing power of bitcoin is a marvel of the modern world.

For all its problems I would say it has a long way to go yet unless the world solves the reality of a borderless economy.

_coldfire··on Is Private Browsing Really Private?
I'm in the same boat, well aware of chrome option to switch accounts, but the simplicity of dual browsers wins when two people use the same login regularly.

Also I get to keep up to date with changes in firefox.

_coldfire··on Copper is key in burning fat
Millions of tonnes of copper are mined every year. Dietary copper is on the scale of micrograms.

Your conspiracy has a problem of many magnitudes.

Taking large doses of anything is never a good idea, normal doses of zinc over a long period is excellent starting advice for many dermatological conditions.

Zinc in general is one of the few supplements shown to actually have benefit for the average human.

_coldfire··on Why Small Businesses Aren’t Spending More on Tech
There's MSoffice for mac, haven't used it but it certainly exists. Unless you mean VBA? Don't see why they'd sell office without macros.
_coldfire··on Why Small Businesses Aren’t Spending More on Tech
I've seen a few companies using google docs because no one knew excel also has a collaborative spreadsheet mode. All had MSoffice.

Last place had about 60 users. Average load time for the gdocs page is ~90 seconds. Users access the page dozens of times a day, most leave it open as a tab but memory usage became an issue.

Ever-increasing spreadsheet size eventually meant multiple computers were crashing/becoming unusable with the sheet open.

I offered to migrate it to Excel/VBA, was an old tiny codebase for simple calculations. Management bought more RAM instead, made me laugh.

_coldfire··on Introducing ProtonMail's Tor hidden service
Correct.

Vanity addresses are popular in bitcoin, but difficulty rises exponentially with each character. Most people don't want crunch random numbers for 6 months. The solution to 3rd party key generation is split keys.

Essentially the addition of keys to get the desired final key.

Generate key X, give X public address to cloud provider, they search for key Y so that X + Y == YourVanityAddress, when found they send you private Y. Private X + Y is your vanity private key.

Vanity address generated by 3rd party in a trustless environment.

That is certainly not the case. Renewables are solved. Storage is not. Until that problem is fixed 24/7 generation sources will still be needed.
_coldfire··on Study: Eating hot chili peppers linked to decreased mortality
It's speculated to be due to capsaicin which is essentially what determines the scovilles rating. No real evidence yet though.

Everything in moderation also, too much vitamin c actually makes it an oxidant in the body. Beta-carotene in vegetables widely acknowledged to lower incidence of lung cancer. Beta-carotene pills given to smokers raised lung cancer rates so much they had to end the study early on ethical grounds.[1]

Nutrition is far from solved. It's naive to isolate a substance from a food and claim it alone causes an effect.

I'm a huge chilli fan, gone through a fair share of super hots and anecdotally don't think they can be good for your digestive system in ultra-large doses, have ruined meals and myself on a few occasions. What I get from the study is perhaps choose a vindaloo over a korma, rather than eat as many reapers as possible in 60 seconds.

The chances of a sha256 collision is essentially zero barring a vulnerability being found in sha2. Far more likely for a comet to wipe out earth in your lifetime.

_coldfire··on Bitcoin slides as China's central bank launches checks on exchanges
China should simply go into another jurisdiction and start investigating it's nationals? It doesn't work like that.

They already have an annual limit of $50,000 that can be transferred out of the country, they also ask foreign countries for help in identifying corrupt officials and individuals transferring large amounts out of the country, rich Chinese have strategies to avoid the law.

In my own country i've seen that request largely ignored. The benefits are simply too high, the Govt here is well aware that sizable portions of this money is likely dirty money, but the bottom line for the economy eases that discomfort.

The push to crack down on foreign housing investment in cities across the world lately has been driven by angry locals and soaring house prices, despite the Chinese govt asking for something to that effect for over a decade.

Simply talking to or about them in your living room can now be a problem ranging from mild annoyance to credit card purchase.
