qyv··on Do not leave XPS laptop in any sleep/hibernate/standby mode when placed in a bag
You can force modern standby to disconnect from networks (connected standby vs. disconnected standby). This helps with stopping the system from waking up randomly.

qyv··on Coinbase S-1
Scarcity itself does not imply value, something can be scarce but if no one wants it it still has no value. So the question needs to be what really drives the value of something like Bitcoin?

In my opinion, I think that Bitcoin derives its value from the idea that one day it will become a widely used currency that can be exchanged universally for real-world goods and services. This has what has driven it to become a speculation tool; because at the end of the day when Bitcoin finally becomes a "universal" currency, everyone wants to be left holding a lot of it. But what if Bitcoin never becomes a currency, what happens to it's value then?

qyv··on JSON with Commas and Comments
Who is to say what to legitimate use and what is misuse of a creation if not the creator?
qyv··on Why traditional reinforcement learning will probably not yield AGI [pdf]
> But those heuristics and hardcoded biases were developed through brute force optimization over the course of billions of years, a massive amount of energy input and many organisms being devoured.

This is true in the context of the universe as a whole, not by the organism itself.

qyv··on Microsoft President: We Need a Hippocratic Oath for Software Engineers
"I was only following orders."

Edit to add: If you are being asked to perform illegal or unethical acts as part of your employment, then perhaps termination is an ideal course of action? Unless of course your personal enrichment outweighs legalities or ethics in your worldview?

qyv··on Evidence that the key assumption made in discovery of dark energy is in error
> However, as you go further and further out from our galaxy the metric expansion of spacetime begins to dominate the relative motion of all bodies, leading to observing progressively redder and redder light curves. A galaxy billions of light years away is perceived to be moving away from our reference frame at a significant percentage of the speed of light!

Is this not because there is simply more space between things that are farther away and therefore more expanding space? So, more space = more magnitude of expansion?

qyv··on Impossible Foods and Beyond Meat's plant-based burgers aren't healthier
Animals have killed other animals for food since the dawn of life. You can't get more"natural" than that. Eating meat is hardly a human invention.
qyv··on Impossible Foods and Beyond Meat's plant-based burgers aren't healthier
I know for a fact that McDonald's beef burgers, at least in North America, have a single ingredient: beef. They go directly from source grind to patty maker to freezer, nothing is added.
qyv··on Software Won’t Fix Boeing’s ‘Faulty’ Airframe
This can actually vary depending on where you are in the world. There are places, like Canada, where the term engineer has a specific definition under the law, and it includes things such as professional ethics and liability.
qyv··on Pilot Who Hitched a Ride Saved Lion Air 737 on the Day Before Deadly Crash
You are correct. And if two crews in 5 months had the same issue either identifying or dealing with the same problem, then perhaps there is an design or training problem error here.
qyv··on Is Matter Conscious? (2017)
What if we all share the same consciousness, but are simply unable to comprehend it? To me the idea that all concious entities are in fact shared is comforting, because it implies that what we do with our lives will always be remembered. Even after our lives end, our singular consciousness, with all of our memories, thoughts and feelings, remains.
qyv··on Design flaw behind MacBook Pro’s “stage light” effect
The question is actually "at what cost?" Sure, all things being equal thinner/lighter is great. BUT, what trade off's are being made in the name of thinness? If you need to sacrifice 50% expected lifetime to make something 0.5mm thinner, is that a good trade off?
qyv··on Happy Birthday, Ruby
IMO monkey-patching built-in classes is idiomatic Ruby!

Edit to add: Actually, now that I think about it, using method_missing would have been even better!

qyv··on Happy Birthday, Ruby
Ruby the Ruby way:

  module FizzBuzz
    def to_fb
      s = ''
      s << (self % 3 == 0 ? 'Fizz' : '')
      s << (self % 5 == 0 ? 'Buzz' : '')
      s << self.to_s if s.empty?
      return s
    end
  end

  Integer.include(FizzBuzz)

  1.upto(100) { |i| puts i.to_fb }
qyv··on What We Learned from a Year of Americans ‘Risking It’ Without Insurance
That is not how public healthcare works in Canada at all.
qyv··on Apple confirms some iPad Pros ship slightly bent, but says it’s normal
Really? So apple intended to ship non-flat tablets? What is the rational for intentionally making only some of these non-flat? What advantage or innovation does the non-flatness of a certain percentage of ipad's allow? I mean it totally seams plausible that they simply neglected to mention how non-flat tablets are the next big innovation when they were announced.

Or, perhaps this is just damage control because it is fucking embarrassing on a "premium" device.

qyv··on Blockchain study finds zero success rate and vendors don't call back
Trusted is the opposite of trustless.
qyv··on Blockchain study finds zero success rate and vendors don't call back
Replace the word blockchain with database and describe how your example works any differently. I'll give you a hint: it doesn't. There is nothing in your example that requires the use of a blockchain. If that beef was tracked in a standard database they would still need to buy beef that was "legit" as far as the database is concerned if they wanted to make a legit claim.

Tracking external assets requires trust, period. And that being the case, what advantage does blockchain bring to the solution?

qyv··on Amazon Quantum Ledger Database
Using a private blockchain has the same issue of trusting a third party. As soon as someone has control of who can write to the ledger, you need to trust them, period.
qyv··on Magnus Carlsen Beats Fabiano Caruana to Win World Chess Championship
Carlsen was a better player within the rules of this tournament. His strategy clearly shows he was playing to win the tournament, not beat the player.
qyv··on iPad Pro
Why are people so eager to leap from computer OS's (MacOS or even Windows) to these walled gardens like iOS? I can't imagine developing software on iOS, because you know the deployment procedure will be straight to the app store. This ends the ability to create, distribute and install software yourself. Is this really what we want???
qyv··on Crypto Coin Tether Defies Logic on Kraken’s Market, Raising Red Flags
The cynical view: there is more money to be made with scam's than legitimacy.
qyv··on Bitcoin’s Price Was Artificially Inflated Last Year, Researchers Say
People will simply look the other way on this as long as it benefits their worldview. Once things go south the cries will be "Tether lied to us, how could we have known?"
qyv··on Amazon device recorded private conversation, sent it out to random contact
No trashing it at all, just contrasting it. I do see the convenience (luxury) of home automation, but when you compare that against accurate mobile mapping, location finding and navigation, the difference in usefulness is orders of magnitude. One can literally save your life.
qyv··on Amazon device recorded private conversation, sent it out to random contact
There is a massive difference between walking a few steps to turn on a light switch (which is only useful when you are in close proximity) vs having a accurate real-time mapping functionality when on the go.

Similarly, there is a massive difference in the privacy implications of listening to every conversation everyone in your home (including guests) is having vs. having your current location known. Wiretapping laws exist for a reason.

qyv··on A blockchain is a specific set of choices suitable for a narrow set of use-cases
Immutable data storage does not require blockchain, period. Using blockchain because you need immutable storage is like using a helicopter to cross the street. Yes it works, but they are way more simple, efficient and straightforward technologies that will do the same job better and without introducing a bunch of unneeded features/complexity.
qyv··on Uber Is Ripping Off Frequent Riders and Here’s How to Avoid It
Companies understand this, that's why you get to pay them a little more for the convenience of not having to shop around.
qyv··on Was there ever really a “sugar conspiracy”?
The case against saturated fats is far from conclusive. Let alone coconut oil, with is mostly MCT's (medium chain triglycerides) as opposed to the more common LCT's (long chain triglycerides).
qyv··on Worries Grow That the Price of Bitcoin Is Being Propped Up
Is anyone actually paying dollars for Tether, or are they just using them to buy/sell other cryptocurrencies?
qyv··on Building for the Blockchain
Just because you use a blockchain doesn't make your implementation trustless, nor censorship resistant.
