lurker456··on CBS's Showtime caught mining crypto-coins in viewers' web browsers
I hate it being done without informed consent. It's also a huge waste of electricity. On the plus side it could lead to micropayment funded instead of ad-funded sites.
lurker456··on Facebook’s war on free will
facebook is as much just a website as the catholic church is just some buildings with a book. there is a lot behind it.
lurker456··on Equifax Stock Sales Are the Focus of U.S. Criminal Probe
If they had a requirement to report each breach promptly, we'd have known far sooner there was a problem there, and the pressure to improve security would have been higher. They have been leaking for years.
lurker456··on Brain-Machine Interface Isn't Sci-Fi Anymore
if the nerve endings between brain and shoulder are there, it could still work. The device would need to give consistent feedback for the brain to be trained. it's similar to a stroke victim learning to walk again.
lurker456··on 60 journalists all spend one week covering Cincinnati's battle with heroin
less, for several reasons

- in the US system, treating symptoms instead of the underlying cause is easier for the doctor and more profitable in the long run.

- "an ounce of prevention is worth a pound of cure"; less patients that wait until pain is unbearable (due to its cost) which then need different treatment.

- less conflict of interest that affect what doctors prescribe

- there is only one buyer, with a strong negotiation position, potential profits are capped

lurker456··on Bank of Canada increases overnight rate target to 1 per cent
The odds of a commercial bank going bust is higher then Germany going bust. Commercial banks only need to keep a few % of the money deposited at them on their books (its called fractional reserve banking), the other 95% or so can be invested or lent out elsewhere. There are regulations that restrict the risk, require hedging, insurance, etc but those don't help much if the insurer or a significant amount of the borrowers go bust as well due to systemic problems.
lurker456··on Bitcoin's Golden Future
bitcoin is a byzantine fault tolerant distributed database, it's performance characteristics are different.
lurker456··on Houston’s Mayor Was Right to Not Evacuate
suburban sprawl is arguably a result of the obsession with cars
lurker456··on Alaska’s Permafrost Is Thawing
And past performance guarantees future performance ?

Also, bear in mind that an overwhelming majority of the people who invented all this good stuff (scientists) agree that we're approaching a cliff.

lurker456··on An Electronic Voting Firm Exposes 1.8M Chicagoans
To paraphrase a comment about virtual currencies: If you have a hard problem and try to solve it with a blockchain, you now have 2 hard problems.
lurker456··on An Electronic Voting Firm Exposes 1.8M Chicagoans
what alternative do you have in mind ?
lurker456··on GOP lawmakers shamed on billboards for trying to repeal net neutrality rules
How many ISPs can you choose from where you live ? They have an effective monopoly or duopoly in many regions in the US.

in addition to that, "but what about google" is no defence for what last mile ISPs are doing. If google ever becomes too ubiquitous as a gatekeeper (it's already at that point according to the EU antitrust commission) they'll also need to be regulated.

lurker456··on Coco: Framework for enterprise blockchain networks
While a 51% attack is a real concern, an even more likely scenario is the network going down. During a network split the local node(s) will happily continue to ingest logs which once the network is healed will all be rejected.
lurker456··on Timescale, an open-source time-series SQL database for PostgreSQL
further evidence of how postgreSQL is eating noSQL. Every good concept first implemented in a custom noSQL solution eventually becomes an extension in postgres.
lurker456··on Coco: Framework for enterprise blockchain networks
A blockchain does not offer that guarantee either. The shared consensus it achieves comes at the cost of occasionally discarding stuff.

The few protections it does offer against tampering can be achieved in a much simpler way for your scenario (signing)

lurker456··on Hacking Voting Machines at Defcon
especially when the customer differs from the users
lurker456··on A Brutal Intelligence: AI, Chess and the Human Mind
While having a plan is important, it's not the only way a human approaches chess. Experienced chess players develop an ability to evaluate positions intuitively. Without being able to explain fully why and without a specific plan in mind, they're able choose the best position out of several options. In a way, it's very similar to a evaluation function without access to its internal logic.
lurker456··on Close-Up View of DNA Replication
I imagine there are not many things with unexpected shapes at that level that aren't accounted for somehow. Anything that doesn't slot into it perfectly will get knocked away by collisions. Bad shapes do exist however (prions) and are a cause of diseases.
lurker456··on Americans from Both Political Parties Overwhelmingly Support Net Neutrality
That's a bit like comparing a water utility company versus a company selling bottled water. One has a natural monopoly (and likely only exists thanks to generous government support), the other does not.
lurker456··on APFS is not safe to use with names which have Unicode normalisation issues
RDBMS's have gone through the same journey. First it was hardcoded, now for many of them we can specify the codepage or UTF encoding and collation of a DB, some even offer it per table or column, and so on.

Filesystems should do the same. Either pick one way and stick to it (expose it as UTF8, with a sensible normalization and collation) or offer several options that can be specified when creating a volume and do on the fly conversions for clients that need it.

lurker456··on Uber Fires Anthony Levandowski
Couldn't google offer him immunity of sorts in return for spilling the beans on Uber ? They dont need to claw back the money, it is pocket change to them. Restricting Uber from entering that market (on potentially near equal footing) is far more valuable.
lurker456··on With state budget in crisis, many Oklahoma schools hold classes four days a week
But spending that $200 billion on primary education doesn't make it disappear in a black hole either.

One could even argue that money spent on DOD budgets trickles down less to the inhabitants of the state that raised the money in taxes in the first place compared to money spent on education.

lurker456··on Chelsea Manning released from prison
Michael Hastings and Kenneth Lay come to mind. No proof obviously.
lurker456··on How a Blind Developer uses Visual Studio [video]
Would that be a bad thing though ? Assuming assistants are ubiquitous. We don't use punch cards in interviews today. Even today whiteboard interviews are sometimes not the best method to fill certain roles.
lurker456··on Leaked document reveals UK plans for wider internet surveillance
Yes, and it's been going on for at least a decade. It's why they rushed through an emergency bill with support from both parties in 2014 to retroactively grant immunity. http://www.theregister.co.uk/2014/07/10/uk_government_rushes...
lurker456··on Coinbase adds support for Litecoin
The amount of dormant coins is not that large anymore. I read somewhere it's on the order of 30%. If they enter all at once the pool it would be a significant haircut for everyone else, but not the end. More significant risks are an 51% attack, a bug in the protocol, a bug in the implementation of a widely used client, or a major government making it illegal to trade them.
lurker456··on Prepack helps make JavaScript code more efficient
it's possible to do such optimizations for a (safe) subset of javascript, such as these pure functions.

Arguably java has a larger subset even today.

lurker456··on Intel platforms from 2008 onwards have a remotely exploitable security hole
why would 3 be unlikely ? The snowden leaks indicate that 3 letter agencies will use high value 0-days sparingly, to ensure they remain 0-days.

Also, there is a 5th (more likely) possibility: SA didn't find anything, but undiscovered holes do exist.

lurker456··on Intel platforms from 2008 onwards have a remotely exploitable security hole
Great news that this finally came to light.

After learning about remote management capabilities I've always suspected it had holes. Large attack surface, any exploit would have a high value, and closed source.

Perhaps one day we'll be able to buy CPU's without this "feature". I'm betting AMD and ARM are in the same boat.
